Compaction can replace visible content without preserving historical usage, and route changes leave the browser without an authoritative context capacity. Cache-write tokens also risk being folded into a cache-hit formula whose denominator has different semantics. + +## Decision + +The Host owns one session-level metrics projection. It incrementally folds the complete durable event log, keys settled usage by `(turn, step)`, and replaces an earlier usage record for the same key instead of double-counting chunk and message forms. Uncached input, output, cache reads, and cache writes remain four disjoint cumulative buckets. Compaction can change the current prompt surface without erasing historical usage. + +Current context pressure is a separate point-in-time value from `tokenMeter.measure(session).totalTokens`. Capacity comes only from `llm.resolveModelInfo(provider, model).context.contextWindow` for the agent's selected route. A route change immediately publishes metrics with capacity absent, then publishes the resolved capacity behind a route generation fence; stale metadata cannot label the new route. + +The tail `session.history` response carries the projection, while older pages omit it. Live changes use `session/metrics` mux frames. Both forms carry a durable-log revision and a projection revision; the client accepts only nondecreasing revisions, preserves metrics across older-page prepend, and clears them at a new subscription baseline. Missing measurement or metadata stays absent. + +The Web stats line treats the projection as its sole token source. It renders uncached input, output, and cache reads separately, computes cache hit as `cacheRead / (uncachedInput + cacheRead)`, and shows current context as a percentage of the exact route capacity. Cache writes never enter that percentage. Visible nodes continue to supply only turn and step counts. + +## Alternatives considered + +**Fold the loaded node window in React.** This cannot survive pagination or compaction and duplicates durable-log semantics in a presentation package. + +**Send usage only with raw assistant events.** Reconnect and older-page stitching would still need the client to reconstruct a full-log aggregate, and duplicate usage forms would need protocol-specific repair there. + +**Reuse one total-token field for cache hit.** Cache reads, cache writes, and uncached input represent distinct provider accounting buckets; combining them would make the displayed rate misleading. + +**Keep the previous capacity until the new route resolves.** The old number would temporarily claim the wrong selected model. An explicit unknown state is honest and generation-safe. + +## Consequences + +Token totals remain stable across pagination, replay, compaction, and browser reconnect. The client stores a small detached projection instead of scanning the conversation window, and the status row remains readable for large histories through compact number formatting. + +The Host performs one incremental log fold per session and schedules live projection updates only for usage, request-header, or surface-changing events; text and reasoning deltas do not publish metrics. Exact capacity resolution is asynchronous and may briefly render as unknown. Deployments without a token meter or model context metadata retain the row and label the unavailable value instead of fabricating one. diff --git a/.agents/notes/implemented/architecture/2026-07-28-host-owned-web-session-metrics.zh.md b/.agents/notes/implemented/architecture/2026-07-28-host-owned-web-session-metrics.zh.md new file mode 100644 index 0000000000..6ad06ea615 --- /dev/null +++ b/.agents/notes/implemented/architecture/2026-07-28-host-owned-web-session-metrics.zh.md @@ -0,0 +1,35 @@ +# Agent Note: Host 拥有的 Web 会话指标 + +Status: implemented + +[English](2026-07-28-host-owned-web-session-metrics.md) | 中文 + +## 问题 + +Web 统计行若根据当前加载的会话节点推导指标，其结果会随分页窗口变化。压缩（compaction）可以替换可见内容，却无法保留历史用量；路由变更会让浏览器缺少权威的上下文容量。缓存写入 token 还可能被计入缓存命中率公式，而该公式的分母具有不同语义。 + +## 决策 + +Host 拥有一项会话级指标投影。它以增量方式归并完整的持久事件日志，按 `(turn, step)` 标识已结算用量；同一标识再次出现时，会替换较早的用量记录，而不会重复统计分片和消息两种形态。未缓存输入、输出、缓存读取与缓存写入保持为四个彼此独立的累计计数项。压缩可以改变当前提示词表层，但不会抹除历史用量。 + +当前上下文压力是一个独立的即时值，取自 `tokenMeter.measure(session).totalTokens`。容量仅来自 `llm.resolveModelInfo(provider, model).context.contextWindow`，并对应 agent（智能体）所选的路由。路由变更时，Host 会立即发布不带容量的指标，再通过路由代际围栏发布解析出的容量；陈旧元数据无法标记新的路由。 + +`session.history` 尾页响应携带该投影，较早页面则省略它。实时变更使用 `session/metrics` mux 帧。两种形式都携带持久日志修订号和投影修订号；客户端只接受不减小的修订号，在向前加载较早页面时保留指标，并在建立新的订阅基线时将其清除。测量值或元数据缺失时，对应字段保持缺失。 + +Web 统计行把该投影视为唯一的 token 数据来源。它分别呈现未缓存输入、输出与缓存读取，通过 `cacheRead / (uncachedInput + cacheRead)` 计算缓存命中率，并把当前上下文显示为精确路由容量的百分比。缓存写入绝不计入缓存命中率。可见节点仍然只提供轮次和步骤计数。 + +## 备选方案 + +**在 React 中归并已加载的节点窗口。** 此方案无法跨越分页或压缩保留数据，还会在展示包中重复实现持久日志语义。 + +**只随原始 assistant 事件发送用量。** 重连和较早页面拼接仍会要求客户端重建完整日志聚合，而且重复的用量形态需要在客户端按协议专门修复。 + +**为缓存命中率复用单一的 token 总数字段。** 缓存读取、缓存写入与未缓存输入是提供方记账中的不同计数项；将它们合并会使显示的比率产生误导。 + +**在新路由解析完成前保留旧容量。** 旧数值会在短时间内错误标示所选模型。显式的「未知」状态能如实反映情况，并避免跨代串扰。 + +## 后果 + +token 总量在分页、回放、压缩和浏览器重连期间保持稳定。客户端存储一项小型脱耦投影，无需扫描会话窗口；状态行采用紧凑数字格式，因此在较长的历史记录中仍然清晰易读。 + +Host 为每个会话执行一次增量日志归并，仅为用量事件、请求头事件或表层变更事件调度实时投影更新；文本与推理（reasoning）增量不会发布指标。精确容量解析为异步操作，因此可能短暂显示「未知」。未部署 token 计量器或缺少模型上下文元数据时，系统仍保留该行，并标示不可用的值，而不会虚构数据。 diff --git a/apps/web/tests/snapshots/fresh-round-trip/ui.expected.md b/apps/web/tests/snapshots/fresh-round-trip/ui.expected.md index dc572023fd..29d039fd53 100644 --- a/apps/web/tests/snapshots/fresh-round-trip/ui.expected.md +++ b/apps/web/tests/snapshots/fresh-round-trip/ui.expected.md @@ -7,22 +7,30 @@ - tab "Trajectory" - tab "Waterfall" - text: "Use the bash tool to run exactly: echo WEB_E2E_OK.

The `command.*` and `skill.*` domains expose the host command registry and skill catalog to clients. Every method addresses one session's agent by `sessionId` (a served session always has an Agent; `command.*` resumes cold sessions through the same path as `session.*`, while `skill.list` resolves the project root from the session header without touching the Agent registry). `command.execute` runs a slash-command line host-side and returns a detached result; the carrier's request signal cancels the running handler. `host/commands-changed` is the catalog invalidation frame: clients refetch `command.list` instead of diffing. diff --git a/packages/host/apiproxy/README.zh.md b/packages/host/apiproxy/README.zh.md index 4175c8fdb9..cfdf0d772a 100644 --- a/packages/host/apiproxy/README.zh.md +++ b/packages/host/apiproxy/README.zh.md @@ -18,7 +18,7 @@ Workspace 列表与 Session 列表是相互独立的重连基线。`workspace.cr `host.pickDirectory` 会打开一个原生目录选择器并返回选中的路径；用户取消时返回 `null`。宿主实现不经 shell 调用平台工具：macOS 使用 `osascript`，Windows 使用以 STA 模式运行的 PowerShell `FolderBrowserDialog`，Linux 使用 Zenity，并以 KDialog 作为回退。选择器函数可在测试中注入。该方法需等待用户完成操作，是唯一不受默认 30 秒超时限制的一元调用；调用方发出的中止信号和连接中止仍会传播至原生进程。浏览器载体另行将这一特权方法限制为仅接受来自回环地址的同源请求。 -`session.history` 按消息边界分页，其尾页（不带 `beforeSeq`）额外携带两项页窗口本身无法提供的会话级数据：进行中局部消息的 chunk 事件，以及 `todos`——整份日志上最后一次 `todo/write` 的整表投影。较早的页面不带 `todos`，因为该投影是会话级而非分页级的；尾页响应缺少该字段意味着整份日志中没有任何 `todo/write`，因此客户端要把缺失字段读作空计划，而不是读作「状态未变」。 +`session.history` 按消息边界分页，其尾页（不带 `beforeSeq`）携带页窗口本身无法提供的会话级投影：进行中局部消息的分片事件；`todos`，即最后一次 `todo/write` 的整表投影；以及 `metrics`，即按 `(turn, step)` 去重的完整日志用量，并在可用时包含当前 token 计量压力和所选精确路由的容量。较早的页面省略会话级投影。实时 `session/metrics` mux 帧携带单调递增的日志修订号与投影修订号，因此客户端会拒绝陈旧帧，并在向前加载较早页面时保留计数器。缓存读取与缓存写入保持为彼此独立的计数项；缓存命中率的分母是未缓存输入加缓存读取。 `command.*` 与 `skill.*` 领域向客户端暴露宿主命令注册表和技能目录。每个方法都通过 `sessionId` 寻址一个会话的 Agent（被服务的会话必有 Agent；`command.*` 经由与 `session.*` 相同的路径恢复冷会话，而 `skill.list` 从会话头解析项目根目录，不触碰 Agent 注册表）。`command.execute` 在宿主侧运行一条斜杠命令行并返回脱耦结果；载体的请求信号可取消正在运行的处理器。`host/commands-changed` 是目录失效帧：客户端重新拉取 `command.list` 而不是做差分。 diff --git a/packages/host/apiproxy/src/api-proxy.ts b/packages/host/apiproxy/src/api-proxy.ts index 58922284be..13aa85c1fe 100644 --- a/packages/host/apiproxy/src/api-proxy.ts +++ b/packages/host/apiproxy/src/api-proxy.ts @@ -40,6 +40,7 @@ import type { } from '@deepseek-ai/dsh-user-interaction' import { UserInteractionError } from '@deepseek-ai/dsh-user-interaction' import { pickNativeDirectory } from './native-directory-picker.ts' +import { affectsSessionMetrics, SessionMetricsProjector } from './session-metrics.ts' /** Page size when history is called without maxMessages. */ const DEFAULT_MAX_MESSAGES = 50 @@ -417,6 +418,54 @@ export function createApiProxy(ctx: Context, defaults: ApiProxyDefaults): ApiPro for (const queue of muxQueues) queue.push(envelope) } + const pendingMetricSessions = new Set() + let metricFlushScheduled = false + let metricsDisposed = false + const metricsProjector = new SessionMetricsProjector( + ctx, + agent => targetFor(agent).current, + (agent) => { scheduleMetrics(agent.session) }, + ) + + /** Queue one full-log metrics publication after synchronous session listeners drain. */ + function scheduleMetrics(session: Session): void { + if (metricsDisposed || muxQueues.size === 0) return + pendingMetricSessions.add(session) + if (metricFlushScheduled) return + metricFlushScheduled = true + queueMicrotask(() => { + metricFlushScheduled = false + if (metricsDisposed) { + pendingMetricSessions.clear() + return + } + const sessions = [...pendingMetricSessions] + pendingMetricSessions.clear() + for (const current of sessions) { + broadcast({ + type: 'session/metrics', + sessionId: current.id, + metrics: metricsProjector.snapshot(current, ctx.agents.get(current.id)), + }) + } + }) + } + + ctx.effect(() => { + const disposers = [ + ctx.on('session/event', (session: Session, event: SessionEvent) => { + if (affectsSessionMetrics(event)) scheduleMetrics(session) + }), + ctx.on('agent/created', (agent: Agent) => { scheduleMetrics(agent.session) }), + ctx.on('session/disposed', (session: Session) => { pendingMetricSessions.delete(session) }), + ] + return () => { + metricsDisposed = true + pendingMetricSessions.clear() + for (const dispose of disposers) dispose() + } + }, 'api-proxy: session metrics') + /** * Per-session inbox mirror serving the mux-open queue snapshot (the same * refresh-recovery baseline as pending questions).

Conflating it with the application's source location would break that boundary and leave installed or externally launched sessions ambiguous. + +**Put Web wording in the global harness identity.** `dsh-system-prompt` serves TUI, ACP, SDK, and custom deployments that do not run in a browser.

The [runtime-context decision](2026-07-28-web-agent-runtime-context.md) supplies the first fact, but a GUI edit still had no executable acceptance target: source edits, artifact builds, a listening process, and the user's existing page were unrelated observations. Repository affordances made a wrong substitute look valid because `apps/web/package.json` exposed `vite` as its `dev` script and bare Vite returned HTTP 200 even though it could not inject `window.__DSH_BOOT__`. + +The incident session recorded three consecutive failures. After changing the theme, turn 2 delegated acceptance to the user with `pnpm run demo:tui` or an unspecified browser application and ran no assembled Web check. Turn 3 read the frontend package script, launched bare Vite on port 5173, treated HTTP 200 as readiness, and reported success; the user instead received the expected missing-`__DSH_BOOT__` white screen. Turn 4 found `dsh web`, rebuilt the shell, started an unmanaged shell-background process on port 3334, and checked only that the new page returned 200 with a boot manifest. It never probed the existing port 3081. In fact, the port-3081 process predated the build, and its static host read the rebuilt dist on the next request, so refreshing the original page already showed the change. Only after the user reported that fact did turn 5 inspect port 3081 and remove the redundant server. + +## Decision + +`dsh web` publishes one canonical loopback URL as both model-visible orientation and a managed shell fact. The `app:web-surface` prompt section says that unqualified references identify this GUI, names the URL, and defines acceptance as rebuilding the affected Web artifacts and verifying that existing URL after refresh. `DSH_WEB_URL` carries the same value into every foreground or managed background bash call, so the agent can query the target without parsing prose or process listings. The section preserves the no-implicit-DOM, route, or screenshot boundary and does not claim that a LAN alias equals the browser's literal address. + +The `apps/web` development script and Vite configuration reject serve mode before opening a port. Their diagnostics identify `apps/web` as a build-only shell, explain that only `dsh web` injects `window.__DSH_BOOT__`, and name the production and HMR entry paths. Vite build mode remains unchanged. + +No server restart or replacement is required merely because static artifacts changed. The host reads `index.html` and static assets on each request, while client bundles are also served from their current files with `no-cache`; a refresh of the existing URL is therefore the acceptance path after the relevant shell and plugin bundles are rebuilt. Starting a separate server proves only that a separate server works. If the user explicitly requests another long-running server, the existing managed background-task contract owns its lifecycle and completion notices; shell `&` is not an alternative lifecycle. + +## Verification + +The keyless fresh-round-trip browser scenario boots the shipped Web composition, drives a real replayed session, snapshots the URL-bearing system-prompt prefix, and invokes the assembled bash tool to prove `$DSH_WEB_URL` equals the scaffold's actual bound URL. A real Vite subprocess test requires serve mode to exit nonzero with the full-host correction. The real-Loader webserver test rewrites a static asset after the process binds and proves the same port returns the new bytes. These assertions inspect prompt state, process exit, shell output, and HTTP bytes rather than an agent's success statement. + +## Alternatives considered + +**Extend only the system prompt.** Rejected because it would leave the target unavailable to tools, preserve the misleading bare-Vite path, and fail to prove how an existing process observes rebuilt artifacts. + +**Remove the `apps/web` development script without guarding Vite.** Rejected because `npx vite`, the exact incident command, bypasses package scripts. Serve mode itself must fail. + +**Automatically restart or replace the current Web process after every edit.** Rejected because the static server already reads current artifacts per request, a restart would interrupt the session that requested the edit, and plugin HMR has a separate explicit `dsh web --dev` composition. + +**Send DOM, route, or screenshots with each request.** Deferred to a separate logged-input design. Stable URL identity closes this feedback loop without claiming browser state the host does not receive. + +## Consequences + +Web prompts gain a dynamic URL paragraph, so provider prefix reuse now varies by bound port. Bash processes gain one non-secret managed environment variable. Bare Vite can no longer be used as a shell-only visual sandbox; developers use the full host or build mode instead. In exchange, GUI work has one mechanically observable target, the unsupported startup path fails before a white screen, and a second port can no longer masquerade as proof that the user's current page changed. diff --git a/.agents/notes/implemented/bug-fix/2026-07-28-web-gui-feedback-loop.zh.md b/.agents/notes/implemented/bug-fix/2026-07-28-web-gui-feedback-loop.zh.md new file mode 100644 index 0000000000..06367b09bd --- /dev/null +++ b/.agents/notes/implemented/bug-fix/2026-07-28-web-gui-feedback-loop.zh.md @@ -0,0 +1,37 @@ +# Agent Note: Web GUI 改动在现有 URL 上闭环 + +Status: implemented + +[English](2026-07-28-web-gui-feedback-loop.md) | 中文 + +## 问题 + +Web agent（智能体）既无法识别承载当前会话的 GUI，也不知道用户正在查看哪个 URL。[运行时上下文决策](2026-07-28-web-agent-runtime-context.md)提供前一项事实，但 GUI 编辑仍然没有可执行的验收目标：源码编辑、产物构建、监听中的进程与用户已打开的页面只是互不关联的观察结果。仓库提供的入口让错误的替代方案显得合理，因为 `apps/web/package.json` 将 `vite` 暴露为 `dev` 脚本，而裸 Vite 即使无法注入 `window.__DSH_BOOT__`，仍会返回 HTTP 200。 + +事故会话记录了连续三次失败。修改主题后，第 2 轮把验收交给用户，要求用户运行 `pnpm run demo:tui` 或打开某个未指明的浏览器应用，自己没有执行任何真实组装的 Web 验证。第 3 轮读取前端包脚本，在 5173 端口启动裸 Vite，把 HTTP 200 当作就绪并报告成功；用户看到的却是符合预期的缺少 `__DSH_BOOT__` 的白屏。第 4 轮找到 `dsh web`，重新构建 Web 外壳，在 3334 端口启动了一个不受管理的 shell 后台进程，并且只检查新页面是否能返回 200 和启动 manifest（元数据清单），始终没有探测现有的 3081 端口。事实上，3081 端口的进程早于此次构建启动，其静态宿主会在下一次请求时读取重新构建的 dist，因此刷新原页面就已经能看到改动。直到用户报告这一事实，第 5 轮才检查 3081 端口并移除冗余服务。 + +## 决策 + +`dsh web` 发布一个规范的回环 URL，同时将其作为模型可见的界面定位信息和受管 shell 事实。`app:web-surface` 系统提示词段说明：未加限定的指代指向此 GUI；该段会给出 URL，并把验收定义为重新构建受影响的 Web 产物，然后刷新并验证现有 URL。`DSH_WEB_URL` 会把同一个值传入每次前台或受管后台 bash 调用，使 agent 无需解析提示词或进程列表即可查询目标。该段保留「不会隐式获得 DOM、路由或截图」这一边界，也不声称局域网别名等于浏览器中的实际地址。 + +`apps/web` 开发脚本和 Vite 配置都会在打开端口前拒绝服务模式。诊断信息会指出 `apps/web` 只是一个仅供构建的外壳，说明只有 `dsh web` 才会注入 `window.__DSH_BOOT__`，并给出生产入口与 HMR（热模块替换）入口路径。Vite 构建模式保持不变。 + +静态产物发生变化时，不需要仅为此重启或替换服务器。宿主会在每次请求时读取 `index.html` 和静态资源，客户端 bundle 也会从当前文件提供，并设置 `no-cache`；因此，重新构建相关外壳与插件 bundle 后，刷新现有 URL 就是验收路径。启动另一个服务器只能证明另一个服务器可用。如果用户明确要求再启动一个长期运行的服务器，则现有受管后台任务契约负责其生命周期和完成通知；shell `&` 不能替代这套生命周期机制。 + +## 验证 + +无密钥的 fresh-round-trip 浏览器场景会启动已交付的 Web 组合，驱动真实的回放会话，对包含 URL 的系统提示词前缀生成快照，并调用组装后的 bash 工具，证明 `$DSH_WEB_URL` 等于测试脚手架实际绑定的 URL。真实 Vite 子进程测试要求服务模式以非零状态退出，并给出改用完整宿主的纠正信息。真实 loader Web 服务器测试会在进程完成绑定后改写静态资源，并证明同一端口返回新的字节。这些断言检查提示词状态、进程退出状态、shell 输出和 HTTP 字节，而不是 agent 的成功声明。 + +## 考虑过的替代方案 + +**仅扩展系统提示词。** 不予采纳，因为这样会让工具仍然无法获得目标，保留具有误导性的裸 Vite 路径，并且无法证明现有进程如何观察重新构建的产物。 + +**删除 `apps/web` 开发脚本，但不为 Vite 添加防护。** 不予采纳，因为事故中实际使用的命令 `npx vite` 会绕过包脚本。服务模式本身必须失败。 + +**每次编辑后自动重启或替换当前 Web 进程。** 不予采纳，因为静态服务器本就会在每次请求时读取当前产物，重启还会中断发起编辑请求的会话，而插件 HMR 已有独立且显式的 `dsh web --dev` 组合。 + +**每次请求都发送 DOM、路由或截图。** 推迟到另行设计的已记录输入机制。稳定的 URL 身份足以闭合本次反馈循环，同时不会声称宿主掌握其未接收的浏览器状态。 + +## 影响 + +Web 提示词会增加一个动态 URL 段落，因此模型提供方的前缀复用会随绑定端口变化。Bash 进程会增加一个非敏感的受管环境变量。裸 Vite 不再能用作只依赖 shell 的视觉沙箱；开发者应改用完整宿主或构建模式。作为交换，GUI 工作有了一个可由机制观察的唯一目标，不受支持的启动路径会在出现白屏前失败，另一个端口也无法再冒充用户当前页面已经改动的证据。 diff --git a/apps/cli/README.i18n.yaml b/apps/cli/README.i18n.yaml index d1c6290a08..bd14674ff9 100644 --- a/apps/cli/README.i18n.yaml +++ b/apps/cli/README.i18n.yaml @@ -2,5 +2,5 @@ # side as of the last confirmed-consistent state.

Compaction can replace visible content without preserving historical usage, while the selected model does not prove that a request used its route or capacity. Cache-write tokens also risk being folded into a cache-hit formula whose denominator has different semantics. ## Decision The Host owns one session-level metrics projection. It incrementally folds the complete durable event log, keys settled usage by `(turn, step)`, and replaces an earlier usage record for the same key instead of double-counting chunk and message forms. Uncached input, output, cache reads, and cache writes remain four disjoint cumulative buckets. Compaction can change the current prompt surface without erasing historical usage. -Current context pressure is a separate point-in-time value from `tokenMeter.measure(session).totalTokens`. Capacity comes only from `llm.resolveModelInfo(provider, model).context.contextWindow` for the agent's selected route. A route change immediately publishes metrics with capacity absent, then publishes the resolved capacity behind a route generation fence; stale metadata cannot label the new route. +Current context pressure is the point-in-time `tokenMeter.measure(session).totalTokens`. Capacity instead belongs to the latest model request observed by the current live mux connection. `LlmService.prepareCall()` retains the context metadata obtained by the exact lookup that also validates reasoning/defaults, and the loop publishes it through one contained `agent/model-request` notification only after the final route has a successfully constructed stream handle. Failed or aborted iteration still counts as a dispatched request; preparation and synchronous construction failures do not. -The tail `session.history` response carries the projection, while older pages omit it. Live changes use `session/metrics` mux frames. Both forms carry a durable-log revision and a projection revision; the client accepts only nondecreasing revisions, preserves metrics across older-page prepend, and clears them at a new subscription baseline.

Durable `metrics` comes from tail history and live `session/metrics` frames, survives older-page prepend, and accepts only nondecreasing log and projection revisions. The Session separately retains capacity from the latest `session/model-request` observed on its current mux connection and overlays it onto metrics across ordinary usage/pressure updates. A later request replaces or clears that value, while `session/subscribed` clears both metrics ordering and capacity; reconnect, restore, and a new subscription therefore show no percentage until another request is observed.

The prepared call retains the exact adapter registration across this asynchronous resolution, `request/header` logging, and terminal dispatch, so HMR cannot mix one adapter's capability result with another adapter's request. After the final stream handle is constructed and before adapter iteration, the loop emits one contained live `agent/model-request` notification with turn, step, final provider/model, and optional registration-bound capacity. Preparation or synchronous stream-construction failures emit nothing; later failure or abortion remains an observed dispatch. The effective config is logged before dispatch, so a listener can change effort between steps without hidden request drift. A route with no registered adapter preserves the proposed config so an `llm/stream` listener can own and short-circuit it; unhandled terminal dispatch still fails with `NO_ADAPTER`. A new loop instance restores the last effort only when its initial provider/model route exactly matches the logged route; a route change discards that opaque model-owned ID and resolves the new model independently. Plugin failure ends the current turn, not the loop. Only final adapter dispatch/iteration failures and terminal in-band error or aborted finishes enter `agent/request-error`; middleware, result processing, tools, and other extension failures close directly. Recovery receives the exact live error, immutable provider facts, immutable prior failures, the immutable retry policy of the adapter registration that served the request, and the turn signal after the failed step closes; the policy is absent if no final adapter served it. A handling listener returns `{ kind: 'retry' }`; the loop closes the failed turn with its error and opens one numbered retry turn without an intervening idle notification. Success clears the consecutive history, and an unhandled failure is terminal. AgentLoop owns one cancellation signal for the current admission or turn. An effective `cancel(cause)` clears pending work unless `keepInbox` is set and cooperatively aborts that signal; idle cancellation is a no-op. Durable `turn/end` records `aborted` for `user` and `parent`, while disposal records `disposed`; undispatched model tool calls receive synthetic `tool/call` and `ABORTED_BEFORE_DISPATCH` result pairs. The cancellation cause changes reporting, not how result context finalized after cancellation is handled. Disposal waits for signal-ignoring work before registry removal.

Every method addresses one session's agent by `sessionId` (a served session always has an Agent; `command.*` resumes cold sessions through the same path as `session.*`, while `skill.list` resolves the project root from the session header without touching the Agent registry). `command.execute` runs a slash-command line host-side and returns a detached result; the carrier's request signal cancels the running handler. `host/commands-changed` is the catalog invalidation frame: clients refetch `command.list` instead of diffing. diff --git a/packages/host/apiproxy/README.zh.md b/packages/host/apiproxy/README.zh.md index 2aae0bd683..4e52058c17 100644 --- a/packages/host/apiproxy/README.zh.md +++ b/packages/host/apiproxy/README.zh.md @@ -20,7 +20,9 @@ Workspace 列表与 Session 列表是相互独立的重连基线。`workspace.cr `host.openPath` 会用操作系统的默认应用打开一个文件系统路径（macOS 为 `open`，Windows 为 `Invoke-Item`，Linux 为 `xdg-open`）。打开器可在测试中注入。浏览器载体对其施加与 `host.pickDirectory` 相同的回环、同源限制。 -`session.history` 按消息边界分页，其尾页（不带 `beforeSeq`）携带页窗口本身无法提供的会话级投影：进行中局部消息的分片事件；`todos`，即最后一次 `todo/write` 的整表投影；以及 `metrics`，即按 `(turn, step)` 去重的完整日志用量，并在可用时包含当前 token 计量压力和所选精确路由的容量。较早的页面省略会话级投影。实时 `session/metrics` mux 帧携带单调递增的日志修订号与投影修订号，因此客户端会拒绝陈旧帧，并在向前加载较早页面时保留计数器。缓存读取与缓存写入保持为彼此独立的计数项；缓存命中率的分母是未缓存输入加缓存读取。 +`session.history` 按消息边界分页，其尾页（不带 `beforeSeq`）携带页窗口本身无法提供的会话级投影：进行中局部消息的分片事件；`todos`，即最后一次 `todo/write` 的整表投影；以及 `metrics`，即按 `(turn, step)` 去重的完整日志用量与当前 token 计量压力。较早的页面省略会话级投影。实时 `session/metrics` mux 帧携带单调递增的日志修订号与投影修订号，因此客户端会拒绝陈旧帧，并在向前加载较早页面时保留计数器。缓存读取与缓存写入保持为彼此独立的计数项；缓存命中率的分母是未缓存输入加缓存读取。 + +上下文容量使用独立的临时 `session/model-request` mux 帧；实际请求到达分派点后，该帧由失败会被收容的 Agent 通知发出。该帧携带轮次、步骤、最终提供方／模型与可选容量，且只发送给当时已经打开的 mux 连接。`session.history`、mux 订阅基线、重连和会话恢复绝不会查询或回放先前的容量；不带容量的帧会显式清除较早的连接本地值。 `command.*` 与 `skill.*` 领域向客户端暴露宿主命令注册表和技能目录。每个方法都通过 `sessionId` 寻址一个会话的 Agent（被服务的会话必有 Agent；`command.*` 经由与 `session.*` 相同的路径恢复冷会话，而 `skill.list` 从会话头解析项目根目录，不触碰 Agent 注册表）。`command.execute` 在宿主侧运行一条斜杠命令行并返回脱耦结果；载体的请求信号可取消正在运行的处理器。`host/commands-changed` 是目录失效帧：客户端重新拉取 `command.list` 而不是做差分。 diff --git a/packages/host/apiproxy/src/api-proxy.ts b/packages/host/apiproxy/src/api-proxy.ts index 440c3a1694..a9a753db66 100644 --- a/packages/host/apiproxy/src/api-proxy.ts +++ b/packages/host/apiproxy/src/api-proxy.ts @@ -6,7 +6,6 @@ import { randomUUID } from 'node:crypto' import { mkdir, stat } from 'node:fs/promises' import { join } from 'node:path' -import { FiberState } from 'cordis' import type { Context } from 'cordis' import { installAgentLlmTarget } from '@deepseek-ai/dsh-agent' import type { @@ -409,26 +408,6 @@ export function createApiProxy(ctx: Context, defaults: ApiProxyDefaults): ApiPro return target } - /** - * Read the best capacity route without taking ownership of foreign routing. - * Web agents expose their live selection; other agents expose only a route - * that already crossed the durable request-header boundary. - */ - function metricsRouteFor(agent: Agent): Pick | undefined { - const installed = targets.get(agent) - if (installed !== undefined) return installed.current - const logged = agent.session.requestHeader()?.config - return logged === undefined - ?

Plugin failure ends the current turn, not the loop. Only final adapter dispatch/iteration failures and terminal in-band error or aborted finishes enter `agent/request-error`; middleware, result processing, tools, and other extension failures close directly. Recovery receives the exact live error, immutable provider facts, immutable prior failures, the immutable retry policy of the adapter registration that served the request, and the turn signal after the failed step closes; the policy is absent if no final adapter served it. A handling listener returns `{ kind: 'retry' }`; the loop closes the failed turn with its error and opens one numbered retry turn without an intervening idle notification. Success clears the consecutive history, and an unhandled failure is terminal. AgentLoop owns one cancellation signal for the current admission or turn. An effective `cancel(cause)` clears pending work unless `keepInbox` is set and cooperatively aborts that signal; idle cancellation is a no-op. Durable `turn/end` records `aborted` for `user` and `parent`, while disposal records `disposed`; undispatched model tool calls receive synthetic `tool/call` and `ABORTED_BEFORE_DISPATCH` result pairs. The cancellation cause changes reporting, not how result context finalized after cancellation is handled. Disposal waits for signal-ignoring work before registry removal.

Repository affordances made a wrong substitute look valid because `apps/web/package.json` exposed `vite` as its `dev` script and bare Vite returned HTTP 200 even though it could not inject `window.__DSH_BOOT__`. -The incident session recorded three consecutive failures. After changing the theme, turn 2 delegated acceptance to the user with `pnpm run demo:tui` or an unspecified browser application and ran no assembled Web check.

Both need the frontend dist and client bundles built (`pnpm run build && pnpm run build:web`). `DSH_TOOLS_MODE` selects the tool presentation mode for the whole Web/headless process: `native` (the schema default when unset), `code` (the `run_code`-only Code Mode wire), or `both`; any other value fails loud at boot through the `dsh-tools` config schema. It is a TEMPORARY seam — process-wide because Loader composition is static — and is removed once the web UI owns per-session tool-mode selection; the TUI surface ignores it (its config tree pins its own mode). diff --git a/apps/cli/README.zh.md b/apps/cli/README.zh.md index e0cf7cd399..c28989de2b 100644 --- a/apps/cli/README.zh.md +++ b/apps/cli/README.zh.md @@ -14,7 +14,7 @@ TUI 界面： - 告知 agent 自身源码所在位置：启动后添加一个命名此 harness checkout 的提示词段。该路径从启动器的真实路径解析，因此在 PATH 符号链接和任意 cwd 下仍然有效，使自指的 `cordis` 工具集可以读取并修改它； - 应用 `~/.dsh` 中的个人覆盖（参见 [app-boot 的个人配置](../../packages/ui/app-boot/README.md#personal-config)）：`.env` 填补环境缺口（环境中已有的值 > 项目 `.env` > 个人 `.env`），`config.yaml` 则修补已启动的树。 -Web 和无头界面启动同一个共享组合（`cordis.yml`）：两者都会告知编码 agent 所用模型和会话工作目录，将调用目录视为默认项目和 Workspace 根目录，除非通过 `--workspace-root ` 覆盖，否则会在该根目录下创建具名 Workspace；它们会把适用的 `AGENTS.md`/`CLAUDE.md` 指令加载到每个 agent-loop 请求前缀中，渲染预算为 65,536 字节，并选用首条消息模型标题。Web 还会明确说明交互界面是 DeepSeek Harness Web GUI、当前 checkout 是自身源码位置，并在提示词和 `$DSH_WEB_URL` 中提供该进程的规范本地 URL；因此，「这个页面」等表述会指向该 GUI，但 agent 不会声称可以访问未显式提供的 DOM、路由或截图状态。Web 宿主会在收到请求时读取前端 dist 和客户端 bundle，因此重新构建受影响的产物并刷新现有 URL 即可更新该 GUI，无须替换其进程；直接使用裸 `apps/web` Vite 服务会失败，因为它无法注入 `window.__DSH_BOOT__`。无头界面唯一的差异是监听操作系统分配的端口（并行 `dsh -p` 运行绝不冲突；stderr 打印的 URL 会在浏览器中打开实时会话）。两者都需要先构建前端 dist 和客户端 bundle（`pnpm run build && pnpm run build:web`）。 +Web 和无头界面启动同一个共享组合（`cordis.yml`）：两者都会告知编码 agent 所用模型和会话工作目录，将调用目录视为默认项目和 Workspace 根目录，除非通过 `--workspace-root ` 覆盖，否则会在该根目录下创建具名 Workspace；它们会把适用的 `AGENTS.md`/`CLAUDE.md` 指令加载到每个 agent-loop 请求前缀中，渲染预算为 65,536 字节，并选用首条消息模型标题。Web 还会明确说明交互界面是 DeepSeek Harness Web GUI、当前 checkout 是自身源码位置，并在提示词及受管的 `$DSH_WEB_URL`/`$DSH_WEB_MODE` 中提供该进程的规范本地 URL 和模式；因此，「这个页面」等表述会指向该 GUI，但 agent 不会声称可以访问未显式提供的 DOM、路由或截图状态。在生产模式下，宿主会在下次请求时读取重新构建的前端 dist 和客户端 bundle，因此刷新现有 URL 即可更新该 GUI，无须替换其进程。`dsh web --dev` 会挂载客户端插件的 HMR（热模块替换）接收端，但要实现无刷新更新，还需在同一 checkout 中运行 `pnpm run dev:web`，以监视并重新构建插件 bundle；shell 和普通包（package）的更改仍需重新构建并刷新页面。直接使用裸 `apps/web` Vite 服务会失败，因为它无法注入 `window.__DSH_BOOT__`。无头界面唯一的差异是监听操作系统分配的端口（并行 `dsh -p` 运行绝不冲突；stderr 打印的 URL 会在浏览器中打开实时会话）。两者都需要先构建前端 dist 和客户端 bundle（`pnpm run build && pnpm run build:web`）。 `DSH_TOOLS_MODE` 为整个 Web／无头进程选择工具呈现模式：可选值为 `native`（未设置时的 schema 默认值）、`code`（仅含 `run_code` 的 Code Mode 协议接口）或 `both`；任何其他值都会经由 `dsh-tools` 配置 schema 在启动时明确报错。它是一个临时 seam：Loader 组合是静态的，因此该设置作用于整个进程；待 Web UI 负责逐会话工具模式选择后便会移除。TUI 界面会忽略该变量（其配置树固定了自身模式）。 diff --git a/apps/cli/src/args.ts b/apps/cli/src/args.ts index 9fd0f4d9bf..0ea3c7e21c 100644 --- a/apps/cli/src/args.ts +++ b/apps/cli/src/args.ts @@ -115,7 +115,7 @@ export function parseDshArgs(argv: readonly string[], version: string): DshInvoc web .option('--host ', 'override the config bind host (127.0.0.1 or 0.0.0.0)') .option('--port ', 'override the config listen port (0 requests an OS-assigned port)') - .option('--dev', 'mount the client HMR driver and watch plugin bundles for rebuilds') + .option('--dev', 'mount the client-plugin HMR receiver (run pnpm run dev:web separately to rebuild bundles)') .option('--workspace-root ', 'parent directory for name-created workspaces') .action((options: WebOptions) => { // Commander parses the parent (default-surface) options on either side of diff --git a/apps/cli/src/web.ts b/apps/cli/src/web.ts index 97e5f94e18..a801929e16 100644 --- a/apps/cli/src/web.ts +++ b/apps/cli/src/web.ts @@ -18,13 +18,23 @@ const CONFIG_PATH = fileURLToPath(new URL('../cordis.yml', import.meta.url)) const SOURCE_ROOT = fileURLToPath(new URL('../../..', import.meta.url)) const DSH_WEB_URL = 'DSH_WEB_URL' as const +const DSH_WEB_MODE = 'DSH_WEB_MODE' as const + +type WebMode = 'production' | 'development' /** Model-visible orientation and acceptance boundary for sessions created through `dsh web`. */ -function webSurfacePrompt(webUrl: string): string { +function webSurfacePrompt(webUrl: string, mode: WebMode): string { + const updateContract = mode === 'development' + ?

It delegated acceptance to the user, then treated a bare Vite HTTP 200 as success despite a missing `window.__DSH_BOOT__` white screen, and finally validated a replacement `dsh web` server on another port while the original page had already picked up rebuilt artifacts. The fix makes the current URL and runtime mode model-visible and shell-queryable, rejects standalone Vite before listen, and verifies production refresh and development HMR against external state. + +## Summary + +The session ran inside the DeepSeek Harness Web GUI at port 3081 while its selected Workspace was an empty `test/` directory. The model request named neither the GUI nor its source checkout, URL, process, or update mode. Repository affordances exposed `apps/web` with a Vite development script, while the full browser composition lived behind `dsh web`. + +The resulting actions were individually plausible but did not share one acceptance target. A source edit, a successful build, an HTTP 200, an injected boot manifest, and the user's existing page were treated as interchangeable facts. + +The evidence source is the persisted event log for `session-3eb796c2-5159-4686-affe-df8719f6f987`, whose header records cwd `/Users/tn.shen/Documents/deepseek-harness-gui-master/test`. Its initial request header is sequence 6; the user-facing handoff, bare-Vite launch, replacement-host launch, boot-manifest probe, and first 3081 process probe are sequences 30939, 31865, 34309, 34441, and 34681 respectively. The timeline below follows those events rather than reconstructing intent from the later report. + +## Impact + +The user had to identify three consecutive mistakes: acceptance was delegated back to them; the proposed preview was a blank page; and the reported successful URL was not the page they were using. An unmanaged replacement server also outlived the turn until the user challenged it. + +No change in this investigation restarted or modified the read-only 3081 and 3082 trial services. + +## Timeline + +- In turn 2, after editing the theme, the agent's sequence-30939 message told the user to run `pnpm run demo:tui` or open an unspecified Web application. It ran no assembled Web acceptance. +- In turn 3, the agent read `apps/web/package.json`, launched bare Vite on port 5173 at sequence 31865, observed HTTP 200, and declared success. The browser instead threw `client-modules: window.__DSH_BOOT__ is missing or not an object` and rendered a white page. +- In turn 4, the agent found the full `dsh web` path, rebuilt the shell, launched an unmanaged process on port 3334 at sequence 34309, and checked only that this replacement returned 200 with a boot manifest at sequence 34441. It never probed port 3081. +- In turn 5, the user reported at sequence 34556 that 3081 already showed the new theme. Only then, at sequence 34681, did the agent inspect the existing process and remove the redundant server. + +## Root cause + +The Web assembly had no model-visible identity for the current GUI, canonical URL, or runtime mode. The session cwd correctly represented the user's selected Workspace, but the model mistook that project boundary for the application boundary. No durable contract related the GUI source checkout, built artifacts, serving process, target origin, and browser acceptance. + +The wrong startup path looked legitimate because bare Vite returned HTTP 200. `window.__DSH_BOOT__` is injected only by the full host, so transport readiness did not imply application readiness. The first regression test repeated this mistake in another form: a timeout killed Vite and satisfied a nonzero-exit assertion. Live reproduction exposed that false positive. + +Background process semantics were also bypassed with shell `&`, so task identity, completion notices, collection, and cleanup did not apply. Verifying port 3334 therefore proved only that a second service worked. + +## Guardrails added + +- The Web launcher publishes the canonical loopback URL and actual production/development mode in the logged `app:web-surface` prompt section and managed `$DSH_WEB_URL`/`$DSH_WEB_MODE` environment. +- Production guidance requires rebuilding artifacts and verifying the existing URL after refresh. Development guidance explains that `dsh web --dev` mounts only the HMR receiver; `pnpm run dev:web` in the same checkout must also rebuild client-plugin bundles, while shell and plain-package changes still require refresh. +- `apps/web` standalone Vite serve mode rejects during configuration. Its subprocess test proves natural exit and instruments `Server.listen()` so a transient bind cannot pass unnoticed. +- Layered real-path tests cover the CLI request, exact production/development prompts, shell runtime facts, same-port static replacement, source watcher rebuild, host stat polling, and browser HMR under an unchanged page identity. +- PR evidence preserves screenshots from the original 3081 session and a real-model before/after GUI run; external browser, HTTP, process, and session-log observations carry acceptance. + +## Lessons + +- The agent must know hidden runtime prerequisites before it can guide the user; startup mode is application context, not tribal knowledge. +- HTTP readiness, build success, and a boot manifest are different facts. Acceptance names the exact origin and externally observes the requested change there. +- A replacement service cannot prove that an existing page changed. Long-running processes use managed task lifecycles when they are actually requested. +- A regression test must be able to fail for the reported mechanism. Process timeout is not equivalent to fail-fast, and post-exit port availability does not prove the port was never bound. diff --git a/docs/postmortem/0003-web-agent-gui-feedback-loop.zh.md b/docs/postmortem/0003-web-agent-gui-feedback-loop.zh.md new file mode 100644 index 0000000000..b3d35db909 --- /dev/null +++ b/docs/postmortem/0003-web-agent-gui-feedback-loop.zh.md @@ -0,0 +1,53 @@ +# 事故复盘（postmortem） 0003：Web agent（智能体）验收了替代服务器，而非其当前 GUI + +[English](0003-web-agent-gui-feedback-loop.md) | 中文 + +Status: resolved + +## 摘要 + +Web agent 修改了 GUI 源码，却不知道由哪个 URL 和进程承载当前会话。它把验收交还给用户，随后在 `window.__DSH_BOOT__` 缺失导致白屏的情况下，仍把裸 Vite 返回的 HTTP 200 当作成功；最后，原页面其实已经加载了重建产物，它却去验收另一个端口上的替代 `dsh web` 服务器。修复让当前 URL 和运行模式对模型可见且可由 shell 查询，在独立 Vite 开始监听前拒绝启动，并依据外部状态验收生产模式刷新与开发模式 HMR（热模块替换）。 + +## 概述 + +该会话运行在端口 3081 的 DeepSeek Harness Web GUI 中，而用户选择的 Workspace 是空的 `test/` 目录。模型请求既未指明该 GUI，也未提供它的源码检出目录、URL、进程或更新模式。仓库在 `apps/web` 中提供了 Vite 开发脚本，完整的浏览器组合则由 `dsh web` 提供。 + +由此产生的各个动作单看都合理，却没有指向同一个验收目标。源码修改、成功构建、HTTP 200、注入的启动 manifest（元数据清单）和用户原本打开的页面，被当成了可以相互替代的事实。 + +证据源是 `session-3eb796c2-5159-4686-affe-df8719f6f987` 的持久化事件日志，其头部记录的 cwd 为 `/Users/tn.shen/Documents/deepseek-harness-gui-master/test`。初始请求头位于序列 6；面向用户的交接、裸 Vite 启动、替代宿主启动、启动 manifest 探测，以及首次探测 3081 进程，分别位于序列 30939、31865、34309、34441 和 34681。下方时间线以这些事件为依据，而不是根据后续报告反推意图。 + +## 影响 + +用户不得不连续指出三个错误：agent 把验收交还给用户；建议预览的页面一片空白；报告成功的 URL 并不是用户正在使用的页面。一个不受管理的替代服务器还持续运行到下一轮，直到用户提出质疑。 + +本次调查没有重启或修改只读的 3081 和 3082 试验服务。 + +## 时间线 + +- 在第 2 轮中，agent 修改主题后，在序列 30939 的消息中让用户运行 `pnpm run demo:tui` 或打开一个未明确指定的 Web 应用。它没有对组装后的 Web 应用执行任何验收。 +- 在第 3 轮中，agent 读取 `apps/web/package.json`，在序列 31865 于端口 5173 上启动裸 Vite，观察到 HTTP 200 后便宣布成功。浏览器却抛出 `client-modules: window.__DSH_BOOT__ is missing or not an object`，并显示白屏。 +- 在第 4 轮中，agent 找到了完整的 `dsh web` 启动路径，重新构建 shell，在序列 34309 于端口 3334 上启动一个不受管理的进程，并且只在序列 34441 检查了这个替代服务是否返回 200 和启动 manifest。它从未探测端口 3081。 +- 在第 5 轮中，用户在序列 34556 报告 3081 已经显示新主题。直到序列 34681，agent 才检查既有进程并移除冗余服务器。 + +## 根因 + +Web 组合没有向模型提供当前 GUI、规范 URL 或运行模式的身份信息。会话 cwd 正确表示了用户选择的 Workspace，但模型误把这个项目边界当成了应用边界。系统也没有持久契约将 GUI 源码检出目录、构建产物、服务进程、目标 origin 和浏览器验收关联起来。 + +裸 Vite 返回 HTTP 200，使错误的启动路径看似合理。`window.__DSH_BOOT__` 只由完整宿主注入，因此传输层就绪不代表应用已就绪。首个回归测试以另一种方式重复了同样的错误：超时机制终止 Vite 后，非零退出断言仍会通过。真实复现暴露了这一误报。 + +agent 还通过 shell `&` 绕过了后台进程语义，因此任务身份、完成通知、结果收集和清理机制均未生效。验证端口 3334 只能证明第二个服务可以工作。 + +## 已添加的防护措施 + +- Web 启动器在记录到日志的 `app:web-surface` 提示词区段，以及受管的 `$DSH_WEB_URL`/`$DSH_WEB_MODE` 环境变量中，发布规范环回 URL 和实际的生产／开发模式。 +- 生产模式指南要求重新构建产物，并在刷新后验证既有 URL。开发模式指南说明，`dsh web --dev` 只挂载 HMR 接收端；同一源码检出目录中的 `pnpm run dev:web` 还必须重新构建客户端插件 bundle，而 Web shell 和普通包的改动仍然需要刷新页面。 +- `apps/web` 的独立 Vite 服务模式会在配置阶段拒绝启动。其子进程测试验证进程自然退出，并插桩 `Server.listen()`，确保短暂绑定端口也不会漏检。 +- 分层的真实路径测试覆盖 CLI（命令行界面）请求、精确的生产／开发模式提示词、shell 运行时事实、同端口静态产物替换、源码 watcher 重建、宿主 stat 轮询，以及页面 identity 不变的浏览器 HMR。 +- PR（Pull Request）证据保留了原始 3081 会话的截图，以及真实模型驱动的 GUI 修改前后对比；验收以外部浏览器、HTTP、进程和会话日志的观测结果为准。 + +## 教训 + +- agent 必须先知道隐藏的运行时前置条件，才能指导用户；启动模式属于应用上下文，不应依赖团队口口相传。 +- HTTP 就绪、构建成功和启动 manifest 是不同的事实。验收必须明确指定确切的 origin，并从外部观察所请求的改动是否在该 origin 生效。 +- 替代服务无法证明既有页面已经改变。确实需要长时间运行的进程时，应使用受管的任务生命周期。 +- 回归测试必须能够针对所报告的机制失败。进程超时不等同于快速失败，进程退出后端口可用也不能证明该端口从未被绑定。 diff --git a/docs/postmortem/README.i18n.yaml b/docs/postmortem/README.i18n.yaml index e68d3a1a07..cbdfd07055 100644 --- a/docs/postmortem/README.i18n.yaml +++ b/docs/postmortem/README.i18n.yaml @@ -1,6 +1,6 @@ # Bilingual-pair consistency record (docs/i18n/README.md): the git blob hash of each # side as of the last confirmed-consistent state.

[中文](2026-07-28-host-owned-web-session-metrics.zh.md) - -## Problem - -A Web stats line derived from the currently loaded conversation nodes is window-dependent under pagination. Compaction can replace visible content without preserving historical usage, while the selected model does not prove that a request used its route or capacity. Cache-write tokens also risk being folded into a cache-hit formula whose denominator has different semantics. - -## Decision - -The Host owns one session-level metrics projection. It incrementally folds the complete durable event log, keys settled usage by `(turn, step)`, and replaces an earlier usage record for the same key instead of double-counting chunk and message forms. Uncached input, output, cache reads, and cache writes remain four disjoint cumulative buckets. Compaction can change the current prompt surface without erasing historical usage. - -Current context pressure is the point-in-time `tokenMeter.measure(session).totalTokens`. Capacity instead belongs to the latest model request attempt observed by the current live mux connection. `LlmService.prepareCall()` retains the context metadata obtained by the exact lookup that also validates reasoning/defaults. After the final provider/model is fixed and the outer `llm/stream` call returns a handle, the loop publishes one contained `agent/model-request` notification. This boundary observes an attempt, not proof of provider I/O: preparation or a synchronous outer waterfall failure emits nothing, while short-circuit handles and later lazy adapter construction, iteration failure, or abort still count. - -The tail `session.history` response carries durable usage and pressure, while older pages omit them. Live changes use `session/metrics` mux frames. Both forms carry a durable-log revision and a projection revision; the client accepts only nondecreasing revisions and preserves metrics across older-page prepend. - -ApiProxy forwards each notification as a distinct `session/model-request` frame only to mux connections already open when dispatch occurs. It never places the frame in `session.history` or a subscription baseline. The client keeps durable `metrics` and transient `modelRequestContextWindow` as separate snapshot fields, replaces or explicitly clears the capacity on the next observed request, and clears both fields on `session/subscribed`; reconnect, restore, and a new subscription therefore start unknown until another request is observed. - -The Web stats line joins the durable projection and live capacity only at presentation. It renders uncached input, output, and cache reads separately, computes cache hit as `cacheRead / (uncachedInput + cacheRead)`, and shows current context as a percentage only when the current connection observed a capacity. Cache writes never enter that percentage. Visible nodes continue to supply only turn and step counts. - -## Alternatives considered - -**Fold the loaded node window in React.** This cannot survive pagination or compaction and duplicates durable-log semantics in a presentation package. - -**Send usage only with raw assistant events.** Reconnect and older-page stitching would still need the client to reconstruct a full-log aggregate, and duplicate usage forms would need protocol-specific repair there. - -**Reuse one total-token field for cache hit.** Cache reads, cache writes, and uncached input represent distinct provider accounting buckets; combining them would make the displayed rate misleading. - -**Query the selected route before dispatch.** Selection may never produce a request, and a second metadata lookup can race the registration-bound lookup that actually validates and dispatches the call. - -**Persist or replay the latest request capacity.** That would make a former request look current on reconnect or restore even though the new connection observed no request. The denominator is deliberately live and opportunistic. - -## Consequences - -Token totals remain stable across pagination, replay, compaction, and browser reconnect. The client stores a small detached durable projection plus one connection-local denominator instead of scanning the conversation window, and the status row remains readable for large histories through compact number formatting. - -The Host performs one incremental log fold per session and schedules durable projection updates only for usage, request-header, or surface-changing events; text and reasoning deltas do not publish metrics. A new connection omits the percentage until it observes a request with context metadata. A later request without metadata clears the denominator, while deployments without a token meter still retain the durable counters and label context unavailable instead of fabricating pressure. diff --git a/.agents/notes/implemented/architecture/2026-07-28-host-owned-web-session-metrics.zh.md b/.agents/notes/implemented/architecture/2026-07-28-host-owned-web-session-metrics.zh.md deleted file mode 100644 index 4535fd8a4b..0000000000 --- a/.agents/notes/implemented/architecture/2026-07-28-host-owned-web-session-metrics.zh.md +++ /dev/null @@ -1,39 +0,0 @@ -# Agent Note: Host 拥有的 Web 会话指标 - -Status: implemented - -[English](2026-07-28-host-owned-web-session-metrics.md) | 中文 - -## 问题 - -Web 统计行若根据当前加载的会话节点推导指标，其结果会随分页窗口变化。压缩（compaction）可以替换可见内容，却无法保留历史用量；所选模型也不能证明某次请求实际采用了该模型的路由或容量。缓存写入 token 还可能被计入缓存命中率公式，而该公式的分母具有不同语义。 - -## 决策 - -Host 拥有一项会话级指标投影。它以增量方式归并完整的持久事件日志，按 `(turn, step)` 标识已结算用量；同一标识再次出现时，会替换较早的用量记录，而不会重复统计分片和消息两种形态。未缓存输入、输出、缓存读取与缓存写入保持为四个彼此独立的累计计数项。压缩可以改变当前提示词表层，但不会抹除历史用量。 - -当前上下文压力是即时的 `tokenMeter.measure(session).totalTokens`。容量则属于当前实时 mux 连接观察到的最新模型请求尝试。`LlmService.prepareCall()` 会保留同一次精确查询取得的上下文元数据，该查询也负责校验推理设置与默认值。最终提供方／模型确定且外层 `llm/stream` 调用返回句柄后，循环会发布一条 `agent/model-request` 通知，并收容该通知的失败。这个边界观察到的是一次尝试，并不能证明提供方 I/O 已开始：准备阶段或外层 waterfall（瀑布式事件）的同步失败不会发出通知，而短路句柄以及之后的惰性适配器构造、迭代失败或中止仍会计入。 - -`session.history` 尾页响应携带持久用量与压力，较早页面则省略这两项。实时变更使用 `session/metrics` mux 帧。两种形式都携带持久日志修订号和投影修订号；客户端只接受不减小的修订号，并在向前加载较早页面时保留指标。 - -ApiProxy 只把每条通知作为独立的 `session/model-request` 帧转发给分派发生时已经打开的 mux 连接。它绝不会把该帧放入 `session.history` 或订阅基线。客户端把持久 `metrics` 与临时 `modelRequestContextWindow` 保存在彼此独立的快照字段中，在观察到下一次请求时替换或显式清除容量，并在收到 `session/subscribed` 时清除这两个字段；因此，重连、恢复和新订阅都会从未知容量开始，直到观察到另一次请求。 - -Web 统计行只在展示时结合持久投影与实时容量。它分别呈现未缓存输入、输出与缓存读取，通过 `cacheRead / (uncachedInput + cacheRead)` 计算缓存命中率，并且只有当前连接观察到容量时，才把当前上下文显示为该容量的百分比。缓存写入绝不计入缓存命中率。可见节点仍然只提供轮次和步骤计数。 - -## 备选方案 - -**在 React 中归并已加载的节点窗口。** 此方案无法跨越分页或压缩保留数据，还会在展示包中重复实现持久日志语义。 - -**只随原始 assistant 事件发送用量。** 重连和较早页面拼接仍会要求客户端重建完整日志聚合，而且重复的用量形态需要在客户端按协议专门修复。 - -**为缓存命中率复用单一的 token 总数字段。** 缓存读取、缓存写入与未缓存输入是提供方记账中的不同计数项；将它们合并会使显示的比率产生误导。 - -**在分派前查询所选路由。** 选择操作可能永远不会产生请求；第二次元数据查询还可能与实际校验并分派调用的、绑定注册项的查询发生竞态。 - -**持久化或回放最新请求的容量。** 即使新连接没有观察到任何请求，这也会让先前请求在重连或恢复后显得仍然有效。该分母刻意只采用实时且恰好可得的数据。 - -## 后果 - -token 总量在分页、回放、压缩和浏览器重连期间保持稳定。客户端存储一项小型、脱耦的持久投影与一个连接本地分母，无需扫描会话窗口；状态行采用紧凑数字格式，因此在较长的历史记录中仍然清晰易读。 - -Host 为每个会话执行一次增量日志归并，仅为用量事件、请求头事件或表层变更事件调度持久投影更新；文本与推理（reasoning）增量不会发布指标。新连接在观察到带上下文元数据的请求之前不会显示百分比。后续不带元数据的请求会清除该分母；未部署 token 计量器时，系统仍保留持久计数器，并把上下文标示为不可用，而不会虚构压力值。 diff --git a/.agents/notes/implemented/architecture/2026-07-28-host-owned-web-session-metrics.i18n.yaml b/.agents/notes/implemented/architecture/2026-07-29-projected-token-usage-and-request-context.i18n.yaml similarity index 52% rename from .agents/notes/implemented/architecture/2026-07-28-host-owned-web-session-metrics.i18n.yaml rename to .agents/notes/implemented/architecture/2026-07-29-projected-token-usage-and-request-context.i18n.yaml index 8c72912377..6aa9498b9c 100644 --- a/.agents/notes/implemented/architecture/2026-07-28-host-owned-web-session-metrics.i18n.yaml +++ b/.agents/notes/implemented/architecture/2026-07-29-projected-token-usage-and-request-context.i18n.yaml @@ -1,6 +1,6 @@ # Bilingual-pair consistency record (docs/i18n/README.md): the git blob hash of each # side as of the last confirmed-consistent state.

It reads `tokenMeter.measure(agent.session).totalTokens` once when the optional service is present and combines the result with the same prepared call's registration-bound `contextWindow`.

From 48192101426c815dede5a88d0dacf1be77988602 Mon Sep 17 00:00:00 2001 From: Hypatia May Date: Thu, 30 Jul 2026 13:53:08 +0800 Subject: [PATCH 032/557] refactor(token-meter): make context occupancy durable projection state Replace the transient `session/model-request` mux frame with ordinary durable session state. Occupancy now rides two last-wins projection fields instead of a non-replayable frame that needed removal tombstones and cross-stream fencing. The frame was the only non-replayable class on the mux stream. Because host and mux are independent SSE streams with no cross-stream order, a request emitted before a removal could arrive after `host/session-removed`, and a legitimate request for a new lifecycle reusing the same id could be fenced by a late removal. Fixing that needed a lifecycle generation on every frame; the frame itself was the problem. Removed: the `session/model-request` frame and schema, the `agent/model-request` core event, the ApiProxy measurement point, the client-side telemetry map and removal tombstone, and the synthetic `cancelled` open error used to signal reconnect through the error channel. Added: `request/context`, a log-only session event recording the registration-bound capacity of the route a request resolved to, appended beside `request/header` from the lookup that already prepared the call and skipped when the route is unchanged. Capacity stays out of `EpochHeader` because it is adapter metadata about a route, not an input the request was built from, so it must not join request reconstruction or header equality. The `contextPressure` projection pairs the newest provider-reported prompt size with the newest recorded capacity. The two are deliberately not one atomic request observation: switching models can pair a fresh capacity with the prior route's pressure until the next request reports usage. The figure is a user-facing reference, and this matches how the TUI status line has always computed occupancy. --- packages/client/connection/src/client/api.ts | 2 +- .../connection/src/client/connection.ts | 26 +- .../client/connection/src/client/fixture.ts | 76 ++++- .../client/connection/src/client/index.ts | 6 +- .../connection/tests/connection.spec.ts | 78 ++--- .../client/connection/tests/fixture.spec.ts | 28 +- packages/client/runtime/README.i18n.yaml | 4 +- packages/client/runtime/README.md | 4 +- packages/client/runtime/README.zh.md | 4 +- packages/client/runtime/src/client/index.ts | 6 +- .../src/client/sessions/conversation.ts | 7 +- .../runtime/src/client/sessions/manager.ts | 34 +- .../runtime/src/client/sessions/session.ts | 115 ++----- .../client/runtime/tests/client-apply.spec.ts | 54 --- packages/client/runtime/tests/fake-api.ts | 9 +- packages/client/runtime/tests/manager.spec.ts | 222 ------------ .../client/runtime/tests/queue-store.spec.ts | 7 - packages/client/runtime/tests/session.spec.ts | 317 +----------------- packages/client/test-runtime/src/fixtures.ts | 1 - .../src/client/chat/ChatView.tsx | 16 +- .../src/client/chat/StatsLine.tsx | 40 +-- .../tests/chat-branch-tails.spec.tsx | 18 +- .../tests/chat-code-subcalls.spec.tsx | 2 +- .../ui-conversation/tests/chat-view.spec.tsx | 13 +- .../tests/gate-branch-tails.spec.tsx | 20 +- .../ui-conversation/tests/input-bar.spec.tsx | 2 +- .../tests/input-matrix.spec.tsx | 2 +- .../tests/input-scenarios.spec.tsx | 2 +- .../ui-conversation/tests/queue-dock.spec.tsx | 2 +- .../ui-conversation/tests/skeleton.spec.tsx | 2 +- .../ui-conversation/tests/todo-panel.spec.tsx | 3 +- packages/core/agent-loop/README.i18n.yaml | 4 +- packages/core/agent-loop/README.md | 2 +- packages/core/agent-loop/README.zh.md | 4 +- packages/core/agent-loop/src/agent.ts | 31 +- .../tests/request-reconstruction.spec.ts | 142 +------- packages/core/agent/README.i18n.yaml | 4 +- packages/core/agent/README.md | 2 +- packages/core/agent/README.zh.md | 2 +- packages/core/agent/src/types.ts | 24 -- .../core/scope/src/scoped-events.generated.ts | 1 - packages/core/scope/tests/invariant.spec.ts | 1 - packages/core/session/src/index.ts | 26 +- packages/core/session/src/invariant.ts | 1 + packages/core/session/src/types.ts | 24 ++ packages/host/apiproxy/README.i18n.yaml | 4 +- packages/host/apiproxy/README.md | 4 - packages/host/apiproxy/README.zh.md | 4 - packages/host/apiproxy/package.json | 7 - packages/host/apiproxy/src/api-proxy.ts | 29 +- .../host/apiproxy/src/api/events.schema.ts | 14 +- packages/host/apiproxy/src/api/events.ts | 30 -- packages/host/apiproxy/src/api/index.ts | 7 +- .../host/apiproxy/src/api/sessions.schema.ts | 2 +- packages/host/apiproxy/src/api/sessions.ts | 8 +- .../tests/api-proxy-model-request.spec.ts | 124 ------- .../host/apiproxy/tests/rpc-schemas.spec.ts | 28 +- packages/host/apiproxy/tsconfig.json | 3 - packages/llm/token-meter/src/index.ts | 3 +- packages/llm/token-meter/src/projection.ts | 27 +- .../llm/token-meter/src/usage-projection.ts | 57 +++- pnpm-lock.yaml | 3 - 62 files changed, 382 insertions(+), 1362 deletions(-) delete mode 100644 packages/host/apiproxy/tests/api-proxy-model-request.spec.ts diff --git a/packages/client/connection/src/client/api.ts b/packages/client/connection/src/client/api.ts index a773269257..a8e561ba33 100644 --- a/packages/client/connection/src/client/api.ts +++ b/packages/client/connection/src/client/api.ts @@ -12,7 +12,7 @@ export type { WorkspaceApi, WorkspaceId, WorkspaceView, CommandsApi, CommandDescriptor, SkillsApi, SkillEntry, ModelCatalogFailure, ModelCatalogModel, ModelProviderGroup, ModelReasoning, - ModelReasoningEffort, ModelRequestTelemetry, ModelTarget, SessionModels, SessionProjectionsBlock, + ModelReasoningEffort, ModelTarget, SessionModels, GoalsApi, GoalRef, } from '@deepseek-ai/dsh-host-apiproxy/api' export type { ToolCallView, ToolResultView } from '@deepseek-ai/dsh-tools/presentation' diff --git a/packages/client/connection/src/client/connection.ts b/packages/client/connection/src/client/connection.ts index 3e748cc68f..6eb6491e2f 100644 --- a/packages/client/connection/src/client/connection.ts +++ b/packages/client/connection/src/client/connection.ts @@ -35,6 +35,10 @@ function sleep(ms: number, signal: AbortSignal): Promise { }) } +/** Coarse connection state for the UI (audit C1): 'connected' after each generation's handshake, + * 'reconnecting' the moment the generation fails (covers the whole backoff+retry span). */ +export type ConnectionState = 'connected' | 'reconnecting' + /** Frame sink callbacks: the Controller owns the physical streams;

A web frontend that wants to render a search result as an expandable per-file group of matches, or as a selectable path list, had to re-parse that text. Both tools already declared a call-time [render intent](../architecture/2026-07-02-tool-render-intent-union.md) (`GenericCallView`, `kind: 'search'`) but no result-time view, so the completed call fell back to the generic card that renders the raw text. + +The structured canonical value does not cross the wire: only the model-facing render text and, when a tool declares `output.presentationMeta`, a JSON metadata payload reach the client, threaded through the `tool/result` event ([canonical-output contract](../architecture/2026-07-20-canonical-tool-output-contract.md)). A result-time view carrying structured data therefore has to project that data into `presentationMeta` and read it back in `presentResult` — the same path `write`/`edit` use for their diff cards. + +## Decision + +`packages/core/tools/src/presentation.ts` adds `card: 'search'` to the `ToolResultView` union as `SearchResultView`, a `kind`-discriminated view that expresses both tools' shapes: `SearchMatchesResultView` (`kind: 'matches'`) carries `grep`'s matches grouped by file as `files: { path, matches: { lineNumber, line }[] }[]`, and `SearchPathsResultView` (`kind: 'paths'`) carries `glob`'s flat `paths: string[]`. Both carry `truncated: boolean` and `total: number`, and an optional `content?: ContentBlock[]`. + +One view with two shapes rather than two cards, because both tools are the same visual object — a search result — and a web consumer switches on one `card` value, then on `kind` for the row shape. The discriminated `kind` keeps each shape's fields non-optional (a matches view always has `files`, a paths view always has `paths`) instead of a single interface where every shape-specific field is optional. + +The card tag is result-time only. A search call stays a `GenericCallView` (`kind: 'search'`): the pending state has no matches or paths to show, so there is nothing a `SearchCallView` would carry that the generic title does not. This is the asymmetry with the terminal card, whose call view carries the command, cwd, and description that exist before execution; a search's structured content exists only after `execute`. + +`packages/fs/tool-fs-search/src/presentation.ts` owns the projection and the narrowing. `grepSearchMeta`/`globSearchMeta` project the canonical value into a `SearchMeta` payload each tool declares as `output.presentationMeta`; `presentGrepResult`/`presentGlobResult` read `result.meta` back through `searchViewFromMeta` and attach the model-facing `result.content` as the view's `content`. The projections apply the SAME inline cap and per-line preview budget the model-facing render applies, and report `total` as every result the search found (before capping) with `truncated` set when the cap dropped results. This is the truncation-honesty point: the model saw a capped inline result plus a spill footer, so the card must not present the retained page as the complete result — a UI reads `truncated`/`total` to show a capped indicator rather than claiming completeness the model never had. + +`searchViewFromMeta` narrows the opaque `meta` defensively and returns `undefined` on any malformed or absent payload, exactly as `diffsFromMeta` does, so a presenter run on an older or hand-edited replayed log falls back to the generic card instead of throwing. `presentResult` returns `undefined` for a failed result, for absent meta (a nested `run_code` dispatch computes no `presentationMeta`), and for the other tool's meta shape (each presenter narrows to its own `kind`). + +The `SearchMeta` member shapes are object-literal `type` aliases, not the `SearchFileMatches`/`SearchLineMatch` interfaces the view exposes. Only a type alias is assignable to the `JsonValue` index signature `presentationMeta` returns; the two are structurally identical, so the projected value still reads back as a `SearchResultView`. + +The TUI (`packages/ui/tui/src/components/transcript.ts`) needs no dedicated arm: its result-view switch handles `terminal` and `diff` explicitly and falls through to a generic arm that renders `view.content ?? this.result?.content`. Because `SearchResultView` carries the model-facing text as `content`, the TUI renders it as the same text it already showed. The web frontend that renders the structured `files`/`paths` shape is a separate later PR; this PR is the backend contract and its two producers. + +## Alternatives considered + +**A single flat `SearchResultView` interface with optional `files?` and `paths?`.** Rejected: it makes both shape-specific fields optional on every value and lets a malformed view carry both or neither. The `kind` discriminant keeps each shape's fields required and lets a consumer switch exhaustively. + +**A call-time `SearchCallView` mirroring the terminal card's both-sides symmetry.** Rejected: a search call has no matches or paths before `execute`, so the view would carry only the title the `GenericCallView` already carries. The terminal card's call view earns its tag because a command, cwd, and description exist at call time; a search's structured content does not. + +**Carry the structured result in a bespoke channel instead of `presentationMeta`.** Rejected: the canonical value is execution-local and never reaches the client, and `presentationMeta` is the established seam that persists a tool's JSON presentation payload with `tool/result` and threads it back to `presentResult`. Adding a second channel would duplicate that path. + +## Consequences + +`grep` and `glob` now compute `presentationMeta` on every non-nested successful call, a bounded projection over the already-parsed matches or paths. The projection re-applies the retention cap the render already applied, so the retained set is computed twice per call; the input is bounded by the raw-output cap, so this is not a new scaling concern. + +A UI without a search card renders the attached `content` text, so no consumer regresses. The web consumer that renders the structured shape reads `truncated`/`total` and the per-file groups; because the view carries only the retained page, a UI wanting the complete result follows the spill locator in the model-facing text, exactly as the model does. + +## Testing + +`packages/fs/tool-fs-search/tests/presentation.spec.ts` pins the pure layer: `groupMatchesByFile`'s first-seen file order, `grepSearchMeta`/`globSearchMeta` projection with the cap applied and `total` reporting the pre-cap count, the per-line preview budget on a projected match line, and `searchViewFromMeta`'s narrowing of both good shapes plus every malformed case (non-object/array meta, missing or mistyped `truncated`/`total`, unknown `kind`, malformed `files` entries, non-string `paths`). `packages/fs/tool-fs-search/tests/tools.spec.ts` pins the wiring through the real tool registry: a capped `grep`/`glob` execute produces the `SearchMeta` on `result.meta` and `presentResult` builds the search view with `content` attached, a nested `run_code` dispatch computes no meta so `presentResult` falls back, and a failed or cross-shape or malformed result falls back to the generic card.

This package owns the trigger and the adoption: the occupant reports one picked path per open through the hole's owner conversation (`open`/`busy`/`onPicked`/`onCancel`/`onError`), and the owner adopts it through the object layer, selecting the committed Workspace only after its list projection has refreshed; cancellation is silent, and errors land in the retryable folder dialog whose **Choose again** reopens the flow. **Create a new workspace** retains the name dialog and disables names already present in that list, while the Host remains authoritative for concurrent or non-UI callers.

Subscription: `subscribe`/`getSnapshot` (always the cached reference) — `implements ObservableSnapshot`, with `useSelector = bindSnapshotSelector(this)` attached at construction, so a Session is directly a uSES source. Frame dispatch is one switch: `session/event` frames dedup by seq (the only dedup key), buffer while open is in flight, otherwise append + incremental projection; open/stitch merges the live buffer by seq and backfills once if `subscribed.lastSeq` outruns the window tail. -- **ConversationSnapshot** (conversation.ts): the immutable snapshot contract — `nodes` (the human transcript, log-ordered), `partial`, `runningCalls`, `pending`, `running`, `removed`, `openState`, `hasMore`, `promptError` and kin. **Reference discipline** (the premise of memo and uSES): the top-level object is fresh on every change; the nodes array is rebuilt but element references come from the cache; unchanged substructures reuse the previous snapshot's references. +- **ConversationSnapshot** (conversation.ts): the immutable snapshot contract — `nodes` (the human transcript, log-ordered), `partial`, `runningCalls`, `pending`, `running`, `removed`, `openState`, `hasMore`, `promptError` and kin. **Reference discipline** (the premise of memo and uSES): the top-level object is fresh on every change; an unchanged nodes projection keeps the same array reference, while a changed flow returns a new array that reuses unchanged element references; unchanged substructures reuse the previous snapshot's references. - **SessionManager** (manager.ts): instance cluster + frame entry + the session list. sessionId-bearing frames go only to existing instances (a mux broadcast must not instantiate every session); approval/question `requested` frames are the exception — they never land in history, so they buffer in `pendingBuffers` and replay on instantiation. - **Notifier** (notifier.ts): two channels chosen by change source. `markDirty()` (default; frame-driven changes always) batches per microtask — N changes, one notification, one re-render; the flush rebuilds the snapshot cache before notifying. `notifyNow()` (only direct echoes of user gestures) rebuilds and notifies in the same tick — controlled inputs roll the DOM back and jump the caret if their echo defers to a microtask. Frame-driven code using notifyNow collapses batching back to per-frame renders; banned. - **TranscriptAdapter / PartialAccumulator**: the transcript is the append-origin surface projected in log order (`isAppendSurfaceEvent` from `@deepseek-ai/dsh-session/surface`) plus one marker per landed compaction checkpoint — never the model surface, which shadows replaced ranges and would erase conversation the reader already saw. Node order is seq-monotonic by construction, so there is no core `seq === index` assertion to satisfy and no degradation branch. Chunks contribute no node (O(1) skip): the accumulator folds StreamChunks into `AssistantBlock[]`, a delta swapping only that block's reference, and the finalizing message discards the accumulator in the same batch (no flicker on promotion).

Performance contract: one append materializes at most one node and copies the projection only when it adds that node; an event that changes no node keeps the previous array reference (a chunk storm costs nothing), and unchanged nodes keep their object identity. ## Code Mode sub-dispatch index diff --git a/packages/client/runtime/README.zh.md b/packages/client/runtime/README.zh.md index 9cebc6e748..efa5e841ef 100644 --- a/packages/client/runtime/README.zh.md +++ b/packages/client/runtime/README.zh.md @@ -24,7 +24,7 @@ SlotsService 分别为 renderer 提供 `useSessions` 与 `useWorkspaces` 的裸 `ConversationSnapshot.nodes` 是人类对话记录，不是模型 surface。`TranscriptAdapter` 按日志顺序投影原始窗口——每个 append 来源的 surface 事件（`isAppendSurfaceEvent`）落在它自己的日志位置上，外加每次落地的压缩检查点贡献一个 `CompactionSummaryNode` 标记——且从不查询 surface 顺序。于是一次落地的压缩会保留它在模型侧遮蔽掉的对话：标记报告模型从哪里开始看不见那段历史，而不是把它抹掉。仅模型可见的 replacement 副本不进入记录：被裁剪的 `tool/result` 和重新生成的 `assistant/message` 只为模型重写一个节点，不标记任何边界。检查点是携带压缩缝隙插件来源、且**替换**了一段 surface 范围的 `user/message`；一条 append 的插件来源 `user/message` 是注入上下文，不是压缩。适配器的插件字面量通过对无 cordis 的 [`dsh-compact/checkpoint`](../../compact/compact/README.md) 叶子做仅类型导入，钉在压缩缝隙自己的声明上：在那里改名会让此处 `tsc` 失败；而对该包做**值**导入会被客户端纯度门禁拒绝，包的**根**即便作为类型也无法到达（它会到达 `dsh-session` 的根，其 `Context` 合并会让 host 的 `sessions` 与本程序的冲突）。`tests/compact-checkpoint-pin.spec.ts` 从行为侧覆盖同一漂移。 -由于投影按日志顺序，节点数组天然按 seq 单调：仅日志的 `command/run` / `command/done` 节点按 seq 插入，`Session` 按分数 seq 归并被打断的冻结节点，而检查点所引范围落在窗口之外的窗口会渲染出标记且不打印任何日志。标记的摘要文本来自检查点的 `compact/summary` 溯源；窗口切分把溯源留在窗口外时该行不可展开而非空白，后续补上溯源的分页会解析出文本。性能契约：一次追加物化一个节点，不改变任何节点的事件保持上一次的数组引用（分片风暴零成本），未变化的节点保持其对象标识。 +由于投影按日志顺序，节点数组天然按 seq 单调：仅日志的 `command/run` / `command/done` 节点按 seq 插入，`Session` 按分数 seq 归并被打断的冻结节点，而检查点所引范围落在窗口之外的窗口会渲染出标记且不打印任何日志。标记的摘要文本来自检查点的 `compact/summary` 溯源；窗口切分把溯源留在窗口外时该行不可展开而非空白，后续补上溯源的分页会解析出文本。性能契约：一次追加最多物化一个节点，并且仅在加入该节点时复制投影；不改变任何节点的事件保持上一次的数组引用（分片风暴零成本），未变化的节点保持其对象标识。 ## Code Mode 子调用索引 diff --git a/packages/client/runtime/package.json b/packages/client/runtime/package.json index 3868ab8d8c..a6f96b9d47 100644 --- a/packages/client/runtime/package.json +++ b/packages/client/runtime/package.json @@ -32,6 +32,7 @@ "license": "BSD-3-Clause", "dependencies": { "@deepseek-ai/dsh-client-connection": "workspace:^", + "@deepseek-ai/dsh-compact": "workspace:^", "@deepseek-ai/dsh-commands": "workspace:^", "@deepseek-ai/dsh-client-ui-slots": "workspace:^", "@deepseek-ai/dsh-host-apiproxy": "workspace:^", @@ -48,7 +49,6 @@ "cordis": "^4.0.0-rc.7" }, "devDependencies": { - "@deepseek-ai/dsh-compact": "workspace:^", "@deepseek-ai/dsh-invariants": "workspace:^", "@types/react": "~18.3.1", "cordis": "^4.0.0-rc.7" diff --git a/packages/client/runtime/src/client/sessions/transcript-adapter.ts b/packages/client/runtime/src/client/sessions/transcript-adapter.ts index 4985f263f4..6fae44ede4 100644 --- a/packages/client/runtime/src/client/sessions/transcript-adapter.ts +++ b/packages/client/runtime/src/client/sessions/transcript-adapter.ts @@ -33,8 +33,8 @@ import { toAssistantBlocks } from './conversation.ts' */ const COMPACT_PLUGIN: typeof COMPACT_CHECKPOINT_SOURCE.plugin = 'compact' -/** In-window tool/call index entry (result-card backfill + runningCalls material). */ -export interface CallIndexEntry { +/** In-window tool/call index entry used to materialize result cards. */ +interface CallIndexEntry { name: string argsRaw: string turn: number @@ -194,11 +194,6 @@ export class TranscriptAdapter { private rev = 0 private nodesResult: { rev: number; value: readonly ConversationNode[] } | null = null - /** In-window tool/call index (Session uses it for runningCalls and result-card backfill). */ - get callIndex(): ReadonlyMap { - return this.callIdx - } - /** * Window rebuild (after open/resync/page prepend): re-index the raw window * and re-project the transcript. @@ -230,9 +225,10 @@ export class TranscriptAdapter { /** * Tail append (live session/event): index the event and, when it belongs to - * the transcript, extend the projection by one node — O(1) per append.

Post-step pressure warns and continues from the latest durable surface — full history if no replacement preceded the attempt, or the pruned surface if pruning already landed. Overflow recovery delegates only before any replacement; generation progress from earlier pruning authorizes a retry from that durable surface unless cancellation or disposal wins. +- **Current lifecycle:** a dangling `compact/start` after the newest `session/end-seed` is the live durable lock and reports busy. +- **Later lifecycle:** a newer constructor-written `session/end-seed` proves that the older unmatched start is stale, so resume, fork, and adoption do not remain wedged by a dead writer. +- **Recoverable failure:** once start lands, the backend makes exactly one `compact/end { error }` attempt. Summary or stability failure leaves the conversation surface unchanged while preserving the failed attempt in the log. If the close append fails, the unmatched start remains intentionally blocking. `compact/end` keeps its `error?` field (mirroring `tool/result`'s self-contained error — one event tells success from failure without correlating a sibling). There is no separate `compact/error` event. -**Core session repair stays compaction-agnostic — deliberately.** `interruptedTurnClosers` is never taught about `compact/*`. Teaching it would force every future `xxx/start … xxx/end` plugin pair to patch a core module — exactly the coupling the capability-seam architecture exists to avoid.

Sending `/compact` as prompt text would spend a model turn and let the conversation model reinterpret a direct control action. Implementing it inside one UI would duplicate command discovery, lifecycle logging, cancellation, and backend policy. + +The human command arrives between turns and must summarize asynchronously. A prompt accepted during that wait must keep its ordinary identity, FIFO position, and wakeup behavior, but it must not derive a request from history that compaction is about to replace. A status check is insufficient: a waking send schedules the driver's claim as a microtask, leaving a same-tick interval where status still reads idle even though the prompt already has right of way. + +Compaction also needs one mutual-exclusion fact shared by manual, pressure, overflow, and explicit-range entry points. A process-local flag alone cannot explain a crash-recovered log, while a summarize-first transaction leaves no durable evidence during the expensive interval. Conversely, treating marker pairs as exclusive containers would forbid valid idle injection even though injection is explicitly non-waking and immediate between turns. + +This note extends the [compaction capability seam](2026-06-18-compaction-capability-seam.md), the [session end-seed boundary](../architecture/2026-07-30-session-end-seed-log-boundary.md), and the [removal of synthetic log-only turns](../simplification/2026-07-28-remove-synthetic-log-only-turns.md). The supersession audit found partial overlap only: each remains active and owns its broader decision. + +## Decision + +### `/compact` is a command over a backend-independent seam + +`@deepseek-ai/dsh-command-compact` registers one argument-free human command through `ctx.commands`. It calls the third abstract `CompactService` operation, `compactNow(agent, signal)`, and maps the closed `ManualCompactionError` taxonomy (`busy | changed | summary | commit | persistence`) to direct UI results. `command/run` and `command/done` preserve the command lifecycle without entering model history or consuming a model-loop turn. + +The seam's `ManualCompactAgentContext` adds only `reserveTurnAdmission()` to the session and routing facts compaction already needs. Retention, balancing, summarization, marker ordering, replacement, and durability remain backend responsibilities. + +### Idle turn admission is synchronously reservable + +`Agent.reserveTurnAdmission(): (() => void) | undefined` claims the boundary before the next ordinary turn. It succeeds only when the driver is idle, no reservation exists, and no accepted waking item already owns the next turn, including a wake whose claim is still a pending microtask. + +The reservation does not create a second queue. Later sends keep their `InboxItemId`, placement, FIFO order, and wakeup facts. `acceptsNextStep` remains false, so waking next-step input becomes an ordinary queued follow-up rather than steering. Release is idempotent and re-arms the existing driver path. `inject()` is not withheld. + +`whenIdle()` treats a reservation as unfinished activity, including when it holds a waking item. Lifecycle teardown still drains the driver's own activity promise rather than awaiting an external operation, so disposal can cancel and unwind without depending on the reservation holder. + +### One parameterized transaction owns every bracket + +`dsh-compact-basic` has one region transaction parameterized by bracket owner (`number | null`), stability rule (whole surface or selected span), and an optional flush. It performs one ordering: + +1. validate the selected positional range and inspect the durable tail; +2. reject a live unmatched compaction marker; +3. append `compact/start` synchronously; +4. prepare and await summarization; +5. revalidate the required stability; +6. append `compact/summary` and the replacement `user/message`; +7. make exactly one `compact/end` attempt; +8. flush when the manual caller requested durability. + +Automatic and explicit-region work use the numeric owner recovered from the open turn and require whole-surface stability. Manual work reserves admission first, selects a useful range before the transaction, and writes nothing when selection returns `null`. Its bracket uses `turn: null`, requires only selected-span stability, and flushes every successfully closed attempt before releasing admission in `finally`. + +`compact/start` is therefore the only compaction lock. There is no `WeakSet`, wrapper mutex, locked/unlocked method split, or redundant activity check around the transaction. + +### Bracket-first deliberately differs from the surveyed implementations + +Codex models manual compaction as a `CompactTask` occupying its active-turn slot while automatic compaction runs inline. Pi uses the existence of a compaction abort controller as its mutex and appends compaction only after success. Claude Code shares one compaction routine between automatic and manual paths but constructs its boundary after summary streaming. + +DSH deliberately records `compact/start` before calling the summarizer. A slow or crashed attempt is observable, automatic and manual paths share the same durable lock, and a later writer cannot mistake an in-flight summary for an unlocked session. This is a conscious divergence from summarize-first behavior, not an accidental event-order difference. + +### Markers are time points, not an event container + +`compact/start` and `compact/end` mean lock acquisition and release. They do not claim exclusive ownership of every event between their seqs. An idle `inject()` may append a `user/message` while a manual summary is pending, so that unrelated event can sit inside the marker interval. + +Manual stability checks only the selected span: it must remain present, contiguous, ordered, equally priced, and balanced. Append-only context outside it does not stale the summary. Positional replacement places the checkpoint at the old span's surface position and leaves injected context after it in derived model history, even though the injection's log seq precedes the later summary and replacement events. + +Failed `changed` or `summary` attempts leave the conversation surface unchanged, but the log is not unchanged: it contains `compact/start` and `compact/end { error }`. User-facing text states that distinction. + +### End-seed distinguishes live and stale orphans + +Tail scanning finds the current turn, unmatched compaction start, and newest `session/end-seed` independently. An unmatched start after the newest end-seed is live and blocks every compaction entry point. An unmatched start before a later end-seed belongs to an earlier session lifecycle and is stale, so it does not wedge the resumed or forked session. + +The compaction invariant uses the same transition logic during seed replay: `session/end-seed` clears an open historical trace. The boundary need not publish live from the constructor for this case; replay is the load-bearing path. + +Once a transaction has appended its start, every later failure makes one closing attempt. A failed close leaves the unmatched start deliberately visible and blocking, and no flush is attempted. A closed manual attempt is flushed even when it reports an expected failure. Cancellation retains exact-reason precedence after required close and flush cleanup. + +### Reference implementation boundaries + +[PR #835](https://github.com/deepseek-harness/deepseek-harness/pull/835) was used as a reference implementation for the command, reservation, tests, and snapshot shape, but was not merged. Its process-local `WeakSet` lock and locked/unlocked method splits were considered and not adopted because the durable bracket is the single reachable lock. + +That reference also carried client-side replacement-anchor machinery to preserve transcript placement. The log-ordered transcript projection already consumes compaction from event order and does not consult mutable surface positions, so those anchors were considered and not adopted. + +## Alternatives considered + +**Check `agent.status` without reserving admission.** Rejected because an accepted waking send can still be waiting on its claim microtask while status reads idle. + +**Queue the command itself.** Rejected because `/compact` is direct control, not model input, and a prompt already accepted first must retain right of way rather than being reordered around a second command queue. + +**Summarize before appending `compact/start`.** Rejected because the expensive in-flight operation would be invisible and would not participate in the lock shared by automatic compaction. + +**Use both a durable marker and a process-local mutex.** Rejected because two authorities can disagree after replay and require wrapper branches for states the bracket already expresses. + +**Hold injection with waking prompts.** Rejected because idle injection is non-waking durable context by contract; delaying it would make plugin ordering depend on a UI command. + +**Require the marker interval to contain only compaction events.** Rejected because markers represent lock time points. Provenance names the selected and shadowed seqs exactly; exclusivity would add no correctness and would reject valid injection. + +**Treat every unmatched marker as permanently busy.** Rejected because a crash-recovered or forked session would remain wedged. `session/end-seed` is the explicit lifecycle evidence that distinguishes stale history from a live process-local attempt. + +## Verification + +Agent-loop tests cover same-tick right of way, preserved IDs and FIFO lifecycle, waking and quiet queued work, idempotent release, `whenIdle()`, cancellation, and teardown. Compact tests cover standalone and numbered invariant ownership, end-seed replay, live versus stale orphans, re-entrant listeners, selected-span drift, commit and close failures, flush ordering, exact cancellation causes, raw output and usage preservation, and automatic/manual mutual exclusion. + +The command package pins registration, Loader composition, argument rejection, exact success/failure text, cancellation, and absence from model history. The `queued-manual-compact` terminal snapshot drives real keystrokes through the assembled TUI: `/help` discovers the command, a held summary admits a queued prompt and immediate injection, `turn: null` markers and the flush precede the queued prompt turn, command lifecycle stays log-only, and the derived order is checkpoint → injection → queued prompt. + +## Consequences + +Interactive users can compact useful history without spending a conversation-model turn. A prompt accepted before the command wins; one submitted during the command waits with its original queue identity. Manual compaction consumes session seqs but no turn number. + +The log exposes slow, failed, crashed, and successful attempts through the same bracket. A stale pre-boundary orphan no longer wedges a new lifecycle, while a current unmatched start remains a hard busy signal. Marker intervals may contain unrelated events, so consumers use provenance and relative ordering rather than assuming a contiguous compaction-only slice. + +The shared transaction keeps one ordering and one lock across every entry point. Failure reporting is precise about whether only the log changed, the surface may have partially changed, or the in-memory commit could not be persisted. diff --git

`/compact` 是基于后端无关 seam 的命令 + +`@deepseek-ai/dsh-command-compact` 通过 `ctx.commands` 注册一个无参数、面向用户的命令。它调用第三个抽象 `CompactService` 操作 `compactNow(agent, signal)`，并把封闭的 `ManualCompactionError` 分类体系（`busy | changed | summary | commit | persistence`）映射为直接 UI 结果。`command/run` 和 `command/done` 保留命令生命周期，同时不进入模型历史，也不消耗模型循环轮次。 + +该 seam 的 `ManualCompactAgentContext` 只在压缩已需使用的会话与路由事实之上增加 `reserveTurnAdmission()`。保留、平衡、摘要、标记排序、替换与持久性仍由后端负责。 + +### 可以同步预留空闲轮次接纳 + +`Agent.reserveTurnAdmission(): (() => void) | undefined` 会在下一个普通轮次之前认领边界。仅当驱动器空闲、没有既存预留，而且尚无已获接纳的唤醒项拥有下一轮次时，它才会成功；仍在等待 microtask 认领的唤醒项也包括在内。 + +该预留不会创建第二个队列。之后发送的项保留其 `InboxItemId`、位置、FIFO 顺序与唤醒信息。`acceptsNextStep` 保持 false，因此唤醒的 next-step 输入会成为普通的排队 follow-up，而不是 steering（中途引导）。释放操作可幂等调用，并重新启用既有驱动器路径。`inject()` 不受阻塞。 + +`whenIdle()` 会把预留视为尚未完成的活动，包括预留持有唤醒项的情况。生命周期 teardown 仍会排空驱动器自身的 activity promise，而不会等待外部操作，因此 dispose（资源释放）可以执行取消并完成退出清理，无需依赖预留持有方。 + +### 一个参数化事务拥有每一对标记 + +`dsh-compact-basic` 只有一个区域事务，由标记归属值（`number | null`）、稳定性规则（整个 surface 或所选 span）与可选 flush 参数化。它按同一顺序执行： + +1. 验证所选位置范围，并检查持久日志尾部； +2. 拒绝活动的未匹配压缩标记； +3. 同步追加 `compact/start`； +4. 准备并等待摘要； +5. 重新验证所需稳定性； +6. 追加 `compact/summary` 与替换用的 `user/message`； +7. 恰好尝试一次 `compact/end`； +8. 当手动调用方要求持久性时执行 flush。 + +自动和显式区域工作使用从开放轮次恢复的数字归属值，并要求整个 surface 保持稳定。手动工作会先预留接纳，在进入事务前选择有效范围；选择结果为 `null` 时不写入任何内容。其标记对使用 `turn: null`，只要求所选 span 保持稳定，并在 `finally` 中释放接纳预留前 flush 每次成功闭合的尝试。 + +因此，`compact/start` 是唯一的压缩锁。不存在 `WeakSet`、包装层 mutex、locked／unlocked 方法拆分，也不存在事务外部重复的活动状态检查。 + +### 先记录标记有意不同于调研过的实现 + +Codex 将手动压缩建模为占用其活动轮次槽位的 `CompactTask`，自动压缩则以内联方式运行。Pi 使用压缩 abort controller 是否存在作为 mutex，并仅在成功后追加压缩。Claude Code 的自动和手动路径共享同一个压缩例程，但会在摘要流结束后才构造边界。 + +DSH 有意在调用摘要器前记录 `compact/start`。缓慢或崩溃的尝试因此可观察，自动与手动路径共享同一个持久锁，之后的写入方也不会把正在生成的摘要误判为未锁定会话。这是对先摘要行为的主动偏离，而不是偶然的事件顺序差异。 + +### 标记是时间点，而不是事件容器 + +`compact/start` 和 `compact/end` 表示获取与释放锁。它们不声称排他拥有二者 seq 之间的每个事件。手动摘要等待期间，空闲的 `inject()` 可以追加 `user/message`，因此该不相关事件可能位于标记区间内。 + +手动稳定性只检查所选 span：它必须仍然存在、连续、有序、计价相同且保持平衡。其外部的仅追加上下文不会使摘要陈旧。位置替换会把检查点放在旧 span 的 surface 位置，并使注入上下文在派生模型历史中位于其后，即使注入的日志 seq 早于后续摘要和替换事件。 + +失败的 `changed` 或 `summary` 尝试会保持会话 surface 不变，但日志并非没有变化：其中会包含 `compact/start` 和 `compact/end { error }`。面向用户的文本会明确说明这一区别。 + +### End-seed 区分活动与陈旧的未匹配标记 + +尾部扫描会分别查找当前轮次、未匹配的 compaction start 与最新 `session/end-seed`。位于最新 end-seed 之后的未匹配 start 是活动锁，会阻塞每个压缩入口点。位于较新 end-seed 之前的未匹配 start 属于更早的会话生命周期，已经陈旧，因此不会卡住恢复或 fork 后的会话。 + +压缩不变量在 seed 回放期间使用同一项转换逻辑：`session/end-seed` 会清除开放的历史追踪状态。此场景不要求构造函数实时发布该边界；回放才是承重路径。 + +事务追加 start 后，每次后续失败都会进行一次闭合尝试。闭合失败会有意留下可见且具有阻塞作用的未匹配 start，并且不尝试 flush。已闭合的手动尝试即使报告预期失败也会 flush。完成必需的闭合与 flush 清理后，取消仍保留原始原因优先级。 + +### 参考实现边界 + +[PR

Effective `cancel(cause)` emits its cause before queue clearing and abort; observers cannot veto; idle calls emit nothing. Durability records user or parent cancellation as `aborted`, teardown as `disposed`; teardown awaits quiescence. The cause affects reporting, not late result-context handling ([decision](../.agents/notes/implemented/architecture/2026-07-16-explicit-turn-cancellation.md)). -Turn and step events are turn-enclosed; idle injected `user/message` events may sit between turns.

Idle injected `user/message` events and standalone manual `compact/* { turn: null }` brackets may sit between turns; neither consumes a turn number. Compaction markers are lock time points rather than an exclusive container, so unrelated idle injection may appear between a manual start and end. Reload closes an interrupted turn tail with a synthetic turn end; `session/end-seed` also separates stale compaction orphans from locks created in the current process lifecycle. After close, only `agent/error` reports turn failures.

Region boundaries preserve tool-call/result pairing but not whole turns, allowing early closed steps of one oversized turn to compact. `dsh-compact-basic` owns thresholds, retained-tail policy, overflow caps, and failure handling. diff --git a/docs/core-data-structures/compaction.zh.md b/docs/core-data-structures/compaction.zh.md index 643a116ff2..20af51b5ac 100644 --- a/docs/core-data-structures/compaction.zh.md +++ b/docs/core-data-structures/compaction.zh.md @@ -2,7 +2,7 @@ [English](compaction.md) | 中文 -压缩 seam 是一个[能力 seam](../../.agents/notes/implemented/architecture/2026-06-13-capability-seams.md)，与 bash 一样分为接口（[dsh-compact](../../packages/compact/compact)，`ctx.compact`）、实现（例如 [dsh-compact-basic](../../packages/compact/compact-basic) 后端）和消费方（延期实现的 `/compact` 工具）。压缩是**一项可选能力**，不属于 agent loop（智能体循环）主干，因此其词汇定义在此而非 [core.md](core.md) 中。基于 tokenizer 或模板的后端是实现同一接口的兄弟包（package）。与 bash 不同，该接口必然依赖 `dsh-session` 和 `dsh-llm`：其动词作用于 agent 所有的 `Session`，而其持久摘要事件使用 `ContentBlock` 词汇（见[压缩能力 seam Agent Note（agent 决策记录）](../../.agents/notes/implemented/feature/2026-06-18-compaction-capability-seam.md)）。 +压缩 seam 是一个[能力 seam](../../.agents/notes/implemented/architecture/2026-06-13-capability-seams.md)，与 bash 一样分为接口（[dsh-compact](../../packages/compact/compact)，`ctx.compact`）、实现（例如 [dsh-compact-basic](../../packages/compact/compact-basic) 后端）和面向用户的消费方（[dsh-command-compact](../../packages/compact/command-compact)）。压缩是**一项可选能力**，不属于 agent loop（智能体循环）主干，因此其词汇定义在此而非 [core.md](core.md) 中。基于 tokenizer 或模板的后端是实现同一接口的兄弟包（package）。与 bash 不同，该接口必然依赖 `dsh-session` 和 `dsh-llm`：其动词作用于 agent 所有的 `Session`，而其持久摘要事件使用 `ContentBlock` 词汇（见[压缩能力 seam Agent Note（agent 决策记录）](../../.agents/notes/implemented/feature/2026-06-18-compaction-capability-seam.md)）。 源码：[`packages/compact/compact/src/types.ts`](../../packages/compact/compact/src/types.ts) @@ -12,12 +12,14 @@ | 事件 | 载荷 | 作用 | |---|---|---| -| `compact/start` | `{ turn }` | 获取日志记录的锁 | +| `compact/start` | `{ turn }` | 获取日志记录的锁；数字标识打开的自动轮次，`null` 标识独立手动尝试 | | `compact/summary` | `{ summary, rawOutput?, shadowedRange, shadowedSeqs, shadowedTokenCount, provider, model, maxTokens?, usage?

An accepted compaction separately replaces an older span with the backend's user-role checkpoint inside a standalone `compact/* { turn: null }` bracket. + +#### Token effect + +The command lifecycle adds no model tokens. A successful compaction reduces later requests by replacing the selected span with one framed summary; summarization itself is one auxiliary request. + +#### KV Cache effect + +Discovery and command bookkeeping do not affect the cache. The accepted surface replacement invalidates reuse from the first shadowed history token. + +## Known Limitations and Deferred Work + +- **Idle-only** — `/compact` reports `busy` when a turn or already accepted waking prompt has right of way; the command itself is not queued. +- **No range or policy arguments** — the argument-free form keeps behavior stable across command adapters. Explicit ranges remain the programmatic `compactRegion()` path. +- **Command adapters only** — surfaces without `ctx.commands` cannot invoke it and rely on automatic pressure compaction. diff --git a/packages/compact/command-compact/README.zh.md b/packages/compact/command-compact/README.zh.md new file mode 100644 index 0000000000..9fb30c6720 --- /dev/null +++ b/packages/compact/command-compact/README.zh.md @@ -0,0 +1,66 @@ +# @deepseek-ai/dsh-command-compact + +[English](README.md) | 中文 + +通过 [`ctx.compact`](../compact/README.md) 提供面向用户的 `/compact` 压缩（compaction）控制。该插件通过 [`ctx.commands`](../../ui/commands/README.md) 注册一个全局命令，因此组合中的每个命令适配器都能发现它；随附 TUI 无需模型轮次即可执行该命令。[排队手动压缩 Agent Note（agent 决策记录）](../../../.agents/notes/implemented/feature/2026-07-30-queued-manual-compaction.md)拥有接纳、锁与持久性决策。 + +## 命令契约 + +| 输入 | 结果 | +|---|---| +| `/compact` | 即使未达到自动压力，也摘要一段有效、平衡的较早范围；独立标记对 flush 后，报告被替换的历史项数量与估算 token 数。 | +| `/compact`，但没有可压缩历史 | `No compactable history yet.`：不会写入标记，也不会变更 surface。 | +| `/compact ` | `Usage: /compact (no arguments)`：该命令不接受参数，也不会调用压缩后端。 | + +该命令与后端无关，只依赖 `compactNow(agent, signal)`。调用该命令的 agent（智能体）就是操作的确切目标，发起分发的 UI 会通过 seam 转发取消信号。每次完成的调用都会记录执行器所属的纯日志事件对 `command/run` / `command/done`；两者都不进入模型历史。 + +预期的 `ManualCompactionError` 代码会成为稳定的直接错误： + +| 代码 | 直接结果 | +|---|---| +| `busy` | `Compaction is unavailable because this process has an active compaction, or the agent is not idle.` | +| `changed` | `The history selected for compaction changed before it could be replaced.

The call replays the conversation's own system prompt, tools, and shadowed-region messages verbatim and appends the compaction instruction as the final user message, so it reuses the provider's warm prefix cache instead of invalidating it. It sets `GenerateOptions.purpose` to `compaction`, which adapters may forward as request attribution (the DeepSeek adapter sends `x-deepseek-harness-compact: 1`) without touching the model-visible body. Only returned text enters the checkpoint, excluding reasoning and tool calls that would leak private reasoning or create an orphaned call. - **Framing** — the replacement user message marks established checkpoint context with `` tags. The raw summary remains on the provenance event, and later automatic cycles merge the prior checkpoint. -- **Lifecycle** — `compactRegion()` mutates `agent.session` and records its start, summary, replacement, and end. After asynchronous summarization it rejects a changed surface-node snapshot, while unrelated log-only events may append without invalidating the selected span. The serial `agent/step` listener checks pressure before request derivation. A canonical provider overflow is offered through `agent/request-error` after the failed step; the plugin compacts there and returns a retry action only after durable surface progress. +- **Lifecycle** — all entry points share one bracket-first region transaction. It validates the range and live lock, appends `compact/start` synchronously, prepares and awaits the summary, revalidates, appends provenance plus the replacement, and makes exactly one closing attempt. Automatic and explicit-region calls require a numeric open-turn owner and whole-surface stability. `compactNow()` reserves idle admission, uses `turn: null`, accepts append-only context outside its selected span, flushes every closed attempt, and releases admission in `finally`. - **Overflow recovery** — provider-confirmed overflow needs no capacity metadata: it bypasses normal pressure and retention, prunes, then attempts one maximal balanced head reduction while leaving the newest indivisible unit. Retry is authorized whenever `surface.replaceGeneration` advances, including when pruning lands before later summary work throws. No replacement, an exhausted target-specific cap, cancellation, or an unknown/noncanonical error preserves the original provider failure. -- **Failure handling** — an unmatched `compact/start` is an inert crash marker because no summary replacement landed. A region failure records an error end; the surface remains unchanged unless pruning already landed. Operational pressure failures warn and continue, while overflow-recovery failure preserves the original provider error only when no earlier replacement advanced the surface. Cancellation remains authoritative after any progress. +- **Failure handling** — a live unmatched `compact/start` is the durable lock. An unmatched marker before a newer `session/end-seed` is stale evidence from a prior lifecycle and does not block; one after that boundary reports `busy`. Summary and changed-span failures close with an error and leave the conversation surface untouched, though the attempt remains in the log. A failed close deliberately leaves a blocking orphan. Operational pressure failures warn and continue, while overflow-recovery failure preserves the original provider error only when no earlier replacement advanced the surface. Cancellation remains authoritative after cleanup and durability. -The protected `summarize()` method is the sole subclass hook.

The shadowed events remain in the raw log, so replay is deterministic. ## Blocking -Compaction is serialized via a log-recorded lock: `compactRegion` refuses to start if the last `compact/start` has no matching `compact/end` after it. The lock is the log (not an in-memory mutex), so it survives replay and a persistence backend can detect an orphaned `compact/start` on reload. The lock brackets the **whole** operation — summarization, the `compact/summary` provenance record, *and* the `user/message` surface replacement all happen before `compact/end` — so a `session/event` listener firing on `compact/end` never observes the lock free while the surface mutation is still pending. The basic backend revalidates the selected surface after summarization: a surface change rejects, while an unrelated log-only append does not invalidate the replacement. `compact/end` is appended even when summarization throws, so a failure can never wedge the lock. +Compaction is serialized by one log-recorded lock shared by all entry points. Tail inspection independently finds the latest unmatched `compact/start` and the newest `session/end-seed`.

Claim publishes `agent/inbox/dequeue` and irrevocably removes the live address before prompt admission, so a racing update cannot rewrite durable history; `cancel()` without `keepInbox` publishes `agent/inbox/discard`. diff --git a/packages/core/agent-loop/README.zh.md b/packages/core/agent-loop/README.zh.md index 6ba945a41e..7b0b158bae 100644 --- a/packages/core/agent-loop/README.zh.md +++ b/packages/core/agent-loop/README.zh.md @@ -55,7 +55,7 @@ interface Config { 实体 `ReactLoopAgent`、其排队输入、outbox 与运行控制均为包内部实现。包根只导出插件／服务／配置契约，包导出映射不提供 `./src/*` 逃逸路径；生命周期拥有方通过 `ctx.agents` 创建 agent，而不是点名、构造或启动驱动器内部组件。一个准备完成的会话只能由一个实体驱动器认领；所有可观测行为都通过会话事件和 `agent/*` 事件分类体系发生。 -统一的 `send()` 原语按（`target` × `wakeup`）路由内容与来源；`followup`/`steer`/`inject` 是它的固定预设别名。`next-turn` 项加入排队 FIFO，除非 `wakeup: false`，否则会唤醒驱动器；接纳发生在任何轮次开启之前。循环在 `agent/prompt-submit` 之前打开一个私有的 next-step 接收窗口，并在 `turn/end` 之前关闭它。在该窗口内，`steer()` 与 `inject()` 会暂存到同一个 outbox；接纳获准后会开启轮次，记录提示词及其返回的 `additionalContexts`，再于首次请求前排空暂存输入。接纳被阻止或失败时，不会写入提示词或钩子生成的上下文。之后，仅含调用方暂存上下文的批次会采用空闲注入的立即追加行为，而 steering（中途引导）及与其一同暂存的上下文则继续待处理，以供重试或之后获准的提示词使用。窗口之外，steering 会成为唤醒驱动器的排队提示词，而注入会立即追加 `user/message`，不开启轮次也不运行模型。 +统一的 `send()` 原语按（`target` × `wakeup`）路由内容与来源；`followup`/`steer`/`inject` 是它的固定预设别名。`next-turn` 项加入排队 FIFO，除非 `wakeup: false`，否则会唤醒驱动器；接纳发生在任何轮次开启之前。`reserveTurnAdmission()` 可以为独立持久操作同步保留该空闲边界：已获接纳的唤醒工作拥有优先权，之后发送的项保留普通队列身份与 FIFO 位置，释放会重新启用同一驱动器路径，`whenIdle()` 会等待预留结束，但 teardown 不会等待它。循环在 `agent/prompt-submit` 之前打开一个私有的 next-step 接收窗口，并在 `turn/end` 之前关闭它。在该窗口内，`steer()` 与 `inject()` 会暂存到同一个 outbox；接纳获准后会开启轮次，记录提示词及其返回的 `additionalContexts`，再于首次请求前排空暂存输入。接纳被阻止或失败时，不会写入提示词或钩子生成的上下文。之后，仅含调用方暂存上下文的批次会采用空闲注入的立即追加行为，而 steering（中途引导）及与其一同暂存的上下文则继续待处理，以供重试或之后获准的提示词使用。窗口之外，steering 会成为唤醒驱动器的排队提示词，而注入会立即追加 `user/message`，不开启轮次也不运行模型。 每次 FIFO 接受项时都会铸造一个 `InboxItemId`，并通过 `agent/inbox/enqueue` 发布完整的单次入队项。`updateInbox()` 持有同步 queued 项边界：编辑会冻结替换内容，但不改变消息标识或位置；移除会发布 discard。编辑会发布 `agent/inbox/update`；steering 项和已被认领的项会返回 `not-found`。认领操作会发布 `agent/inbox/dequeue`，并在提示词接纳前不可逆地移除实时寻址标识，因此竞态中的更新无法改写持久历史；`cancel()` 在不带 `keepInbox` 时会发布 `agent/inbox/discard`。 diff --git a/packages/core/agent-loop/src/agent.ts b/packages/core/agent-loop/src/agent.ts index 1a317aa342..99edf08ca6 100644 --- a/packages/core/agent-loop/src/agent.ts +++ b/packages/core/agent-loop/src/agent.ts @@ -2,7 +2,8 @@ * Concrete Agent loop over two pending-input lists: queued prompts each open a * turn that logs its admitted input after `turn/start` commits, while steering * and injected context enter through the outbox at step boundaries.

Selecting a Workspace invokes the slot owner's `onPick` callback to retarget the frontend Session object. Each registration declares a **directory-flow child hole** (`single` kind: `conversation.hero.workspace.directoryFlow` / `sidebar.workspaces.directoryFlow`) that the composed picker package's client half fills with its picking interaction — the [`-native`](../../host/directory-picker-native/README.md) backend's renderless OS-chooser driver today, an in-app browsing dialog under a `-browse` composition. The flat **Open local folder...** action renders only while the surface's hole is occupied (occupancy read per menu render; an empty hole means the composition has no picking affordance — the seam's documented no-flow default). This package owns the trigger and the adoption: the occupant reports one picked path per open through the hole's owner conversation (`open`/`busy`/`onPicked`/`onCancel`/`onError`), and the owner adopts it through the object layer, selecting the committed Workspace only after its list projection has refreshed; cancellation is silent, and errors land in the retryable folder dialog whose **Choose again** reopens the flow. **Create a new workspace** retains the name dialog and disables names already present in that list, while the Host remains authoritative for concurrent or non-UI callers. The runtime Session and Workspace services own materialization. The Workspace row's Delete action opens a confirmation that states the retention boundary, blocks duplicate submission, and keeps failures open; success removes the group while its Sessions remain under Ungrouped. The Session row's Rename action opens the same browser-owned dialog pattern prefilled with the row's display title: no client-side conflict rule exists (the host normalizes and may reject with `title-invalid`, rendered in the dialog alert), and confirming an unchanged title is deliberately allowed — it pins the current automatic title against regeneration. -Session rows distinguish the runtime's live `waitingApproval` fact from an otherwise blue in-flight Session: an amber warning dot takes precedence over the running indicator, an accompanying visually hidden label exposes the state to assistive technology, and the hover card reports **Waiting for approval** until the request is resolved.

That view already reaches the browser — host, connection, and runtime deliver it onto `ConversationSnapshot` as `resultView` — but the Web client ignored it: every non-terminal, non-diff tool result fell through to the generic card, which renders the model-facing text. A web frontend that wants an expandable per-file group of matches, or a scannable path list, had only the pre-formatted text. + +This is the follow-up the search render card note names: that PR was the backend contract and its two producers; this PR is the web consumer. + +## Decision + +`SearchBlock` is a `ui-primitives` component that renders a completed search as either shape, and the Web render sites for a `grep`/`glob` call consume the search render intent through it. `ui-conversation/src/client/contract/search-card-model.ts` is the single place that turns the snapshot's `resultView` into the component's props, so no render site re-derives the shape. It returns null — the generic path — whenever the result view is not a search card, including a still-running call (a search card is result-time only, so there is nothing before `execute`), a generic result a `grep`/`glob` failure or a nested `run_code` dispatch produces, a terminal result view, and a `card` value this client version does not know. + +The asymmetry with the terminal card is deliberate and inherited from the backend contract: `terminalCardModel` reads both `callView` and `resultView` because a command, cwd, and description exist at call time; `searchCardModel` reads only `resultView` because a search's matches or paths exist only after execution. A running search row therefore shows its summary alone, with no card. + +One component draws both shapes, discriminated by `kind`, because `grep` and `glob` are the same visual object — a search result. `SearchMatchesBlockProps` (`kind: 'matches'`) and `SearchPathsBlockProps` (`kind: 'paths'`) keep each shape's fields required rather than a single interface with everything optional. The component flattens whichever shape it holds into one list of render rows — a file header row plus its match rows for the matches shape, one path row per path for the paths shape — so the height cap counts a file header as one row exactly as a match line or a path, and the head/tail slice arithmetic is `TerminalBlock`'s (`ceil(max/2)` head, the remainder tail), so a long search result and a long command output cut at the same place across the two cards. + +The component's contract: + +- **Grouped matches, collapsible per file.** Each file is a header row (a bold path plus its match count, the whole row the collapse control) followed by its `lineNumber: line` rows. Collapsing a group drops its match rows from the flattened list and from the height cap's arithmetic, but never from the copy text. +- **Flat path list.** The paths shape renders one path per row, no headers. +- **A capped indicator.** When `truncated`, a pill reads `已截断 · 共 {total}` beside the banner summary, so the card never presents a capped page as the complete result — a reader who wants the rest follows the spill locator in the model-facing text, exactly as the model does. The banner summary is a plain structural count (`{n} 处匹配 · {m} 个文件`, or `{n} 个路径`). +- **No soft wrapping.** Result rows are `white-space: pre` inside a horizontally scrolling box, so a long match line or a deep path scrolls sideways rather than folding. +- **Height cap with an expand control.** More than `DEFAULT_SEARCH_MAX_LINES` (16) rows shows a head/tail slice with a button reporting the hidden count, the same shape and arithmetic as `TerminalBlock`. +- **Copy.** The copy control writes the whole structured result — every file and match, or every path — regardless of the height cap or which groups are collapsed, so the clipboard carries the result rather than what the card happens to be showing. + +Geometry, radius, and fonts mirror `CodeBlock` and `TerminalBlock`, so a search card reads as one family with them; `white-space: pre` plus horizontal scroll is the shared deliberate divergence. + +### Render sites + +Three sites consume the derivation, mirroring the terminal card's placement exactly: + +- **The keyed `SearchRow`** (`toolviews/search-sample.tsx`) registers ONE component under both `grep` and `glob` in the `conversation.chat.toolview` keyed hole, and renders the card RESIDENT under the summary row, capped at `CHAT_SEARCH_MAX_LINES` (8) — the same posture `BashRow` takes for its terminal card. Both tool names get the same row because the derived `kind` decides the shape, so a second component would duplicate it. (This resident posture matches the current terminal/diff cards; a separate later PR unifies the whole-row collapse/expand interaction and flips all resident cards at once — out of scope here.) +- **The generic fallback** (`chat/GenericToolCard` → `chat/ToolRow`) threads the derived model as an expand-gated body, the same arm `terminal` uses: a `grep`/`glob` result with no keyed row (none in the shipped app, since both are registered) still renders its card behind the row's expand toggle. +- **The details panel** (`skeleton/DetailsPanel`) renders the card at the primitive's own full height in the Output section, keeping the JSON Input section. + +`CHAT_SEARCH_MAX_LINES` (8) is the row cap, half the primitive's default the panel keeps, for the same reason as `CHAT_TERMINAL_MAX_LINES`: the chat flow is a summary surface read across many calls, the panel is the single-call reading surface. + +## Alternatives considered + +**Two card components, one per tool.** Rejected: `grep` and `glob` are the same visual object discriminated only by `kind`, so two components would duplicate the banner, the height cap, the copy control, and the no-wrap geometry. One component switching on `kind` is what the backend's single `card: 'search'` view is for. + +**A `SearchCallView` so the row renders a card while the search runs.** Rejected: the backend contract deliberately has no call-time search view — a search has no matches or paths before `execute`. The running row shows its summary alone, and `searchCardModel` returns null for a running block, which is faithful to what exists. + +**Reuse `TerminalBlock` or `CodeBlock`.** Rejected: neither models per-file collapsible groups or a truncation pill, and both would need the grouped-matches shape bolted on. The three blocks share their geometry and font tokens instead, which is the only part where one implementation is correct for all. + +## Consequences + +`SearchBlock` reads only the search view's fields, so it stays a pure function of what the render intent carries — no session lookups, replay-safe like the presenters that produce the view. A UI without the search capability still gets the bridge's fenced fallback; nothing about the tool's result shape changed. Extending `ToolRow` with a `search` body prop adds one arm beside `terminal`; a call carries at most one card kind, so the two are never both present on a row. + +## Testing + +`packages/client/ui-primitives/tests/search-block.spec.tsx` pins the component at per-file 100%: both kinds, the truncation pill with its pre-cap total, the empty arm, per-file collapse/re-expand without touching neighbours, a file header counting as one capped row alongside its matches, the head/tail cap and its expand control across both shapes and the no-tail and default-cap edges, and the copy control writing the whole structured result on the accepted and refused clipboard paths. + +`packages/client/ui-conversation/tests/search-card.spec.tsx` pins the wiring at every render site: `searchCardModel`'s derivation for both kinds, the truncation signal, the replacement title, and each null arm (running, no views, generic, terminal, unknown card); the chat row's expand-gated matches and paths bodies through `GenericToolCard` against the non-search args-JSON body; `SearchRow`'s resident card for both kinds, its agreement with the summary row's run state, the replacement-title precedence, and the keyed registration under both `grep` and `glob` with one component; and the details panel's Output section for both kinds against the non-search flattened form. `packages/client/ui-conversation/src/*` sits on the coverage exclude list, so this file is written against no gate pressure. `packages/client/connection/src/client/fixture.ts` gains a `grep` turn

在覆盖排除清单上，因此该文件不受 gate 压力。`packages/client/connection/src/client/fixture.ts` 新增一个发出 `kind: 'matches'` 的 `grep` turn 与一个发出 `kind: 'paths'` 的 `glob` turn 作为 `resultView`，两者都截断，驱动 built-boot snapshot 与实时

Your working directory is {{cwd}}.\n\nVerify your work by running the code or tests. Keep answers brief and factual.\n\n\nUse the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.\n\nUse the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.\n\nCheck the [exit code: N] marker on every bash result; investigate failures before moving on.\n\nTrack every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.\n\nUse the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.\n\n## Writing code for run_code\n\nPass `run_code` the body of an async TypeScript function (erasable syntax only — no `enum` or namespaces; type annotations are advisory, the code runs type-stripped). Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Independent read-only calls MAY overlap under `Promise.all` (safe calls run concurrently; mutating calls run alone, in submission order). Sequence dependent work with `await`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ntype JsonValue = null | boolean | number | string | JsonValue[] | { [key: string]: JsonValue }\n\ninterface ToolArgsMap {\n  /** Execute a bash command (`bash -c`) and return its stdout/stderr. Each call runs in a fresh shell: no state (cwd, variables, functions) persists between calls — pass `workdir` instead of using `cd`. Non-zero exits are reported as `[exit code: N]`. Current harness environment facts are exposed through managed `$DSH_*` variables; inspect them when needed. Commands may run under a file sandbox; a blocked file operation is reported as `[sandbox: file access denied under  mode]` — a policy denial, not a bug in the command; do not retry another way. Long output is truncated to its tail; the full output is saved to a file whose path is reported when available. Set `run_in_background: true` for long-running commands: the call returns a task id immediately; read its output with `task_output` and stop it with `task_kill`. */\n  bash: {\n    /** The bash command to execute. */\n    command: string;\n    /** Clear, concise description of what this command does in active voice, 5-10 words (shown in the UI).

It does not create files, install a package, change cordis.yml or personal/project config, survive restart, or automatically become permanent. To keep it, ask the Agent to implement a normal local, project, or repository Plugin through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime. */\n  cordis_mount: {\n    /** JavaScript body returning a temporary Plugin; evaluated now and saved nowhere. */\n    code: string;\n  } & Record;\n  /** Unmount a current-process temporary Plugin created by cordis_mount.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn. The workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result. Script-body hooks: - `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly. - `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages. - `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`. - `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim. Misused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`. Constraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

Your working directory is {{cwd}}.\n\nVerify your work by running the code or tests. Keep answers brief and factual.\n\n\nUse the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.\n\nUse the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.\n\nCheck the [exit code: N] marker on every bash result; investigate failures before moving on.\n\nTrack every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.\n\nUse the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.\n\n## Writing code for run_code\n\nPass `run_code` the body of an async TypeScript function (erasable syntax only — no `enum` or namespaces; type annotations are advisory, the code runs type-stripped). Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Independent read-only calls MAY overlap under `Promise.all` (safe calls run concurrently; mutating calls run alone, in submission order). Sequence dependent work with `await`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ntype JsonValue = null | boolean | number | string | JsonValue[] | { [key: string]: JsonValue }\n\ninterface ToolArgsMap {\n  /** Execute a bash command (`bash -c`) and return its stdout/stderr. Each call runs in a fresh shell: no state (cwd, variables, functions) persists between calls — pass `workdir` instead of using `cd`. Non-zero exits are reported as `[exit code: N]`. Current harness environment facts are exposed through managed `$DSH_*` variables; inspect them when needed. Commands may run under a file sandbox; a blocked file operation is reported as `[sandbox: file access denied under  mode]` — a policy denial, not a bug in the command; do not retry another way. Long output is truncated to its tail; the full output is saved to a file whose path is reported when available.

This creates an in-memory runtime Plugin, not an installed or configured Plugin. It remains active across later turns until cordis_unmount, toolset unload, or DSH restart. It does not create files, install a package, change cordis.yml or personal/project config, survive restart, or automatically become permanent. To keep it, ask the Agent to implement a normal local, project, or repository Plugin through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime. */\n  cordis_mount: {\n    /** JavaScript body returning a temporary Plugin; evaluated now and saved nowhere. */\n    code: string;\n  } & Record;\n  /** Unmount a current-process temporary Plugin created by cordis_mount.

This creates an in-memory runtime Plugin, not an installed or configured Plugin. It remains active across later turns until cordis_unmount, toolset unload, or DSH restart. It does not create files, install a package, change cordis.yml or personal/project config, survive restart, or automatically become permanent. To keep it, ask the Agent to implement a normal local, project, or repository Plugin through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime.","parameters":{"type":"object","properties":{"code":{"type":"string","description":"JavaScript body returning a temporary Plugin; evaluated now and saved nowhere."}},"required":["code"]}},{"name":"cordis_unmount","description":"Unmount a current-process temporary Plugin created by cordis_mount.

Your working directory is {{cwd}}.\n\nVerify your work by running the code or tests. Keep answers brief and factual.\n\n\nUse the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.\n\nUse the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.\n\nCheck the [exit code: N] marker on every bash result; investigate failures before moving on.\n\nTrack every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.\n\nUse the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.\n\n## Writing code for run_code\n\nPass `run_code` the body of an async TypeScript function (erasable syntax only — no `enum` or namespaces; type annotations are advisory, the code runs type-stripped). Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Independent read-only calls MAY overlap under `Promise.all` (safe calls run concurrently; mutating calls run alone, in submission order). Sequence dependent work with `await`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ntype JsonValue = null | boolean | number | string | JsonValue[] | { [key: string]: JsonValue }\n\ninterface ToolArgsMap {\n  /** Execute a bash command (`bash -c`) and return its stdout/stderr.

Current harness environment facts are exposed through managed `$DSH_*` variables; inspect them when needed.

This creates an in-memory runtime Plugin, not an installed or configured Plugin. It remains active across later turns until cordis_unmount, toolset unload, or DSH restart. It does not create files, install a package, change cordis.yml or personal/project config, survive restart, or automatically become permanent. To keep it, ask the Agent to implement a normal local, project, or repository Plugin through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime. */\n  cordis_mount: {\n    /** JavaScript body returning a temporary Plugin; evaluated now and saved nowhere. */\n    code: string;\n  } & Record;\n  /** Unmount a current-process temporary Plugin created by cordis_mount.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn. The workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result. Script-body hooks: - `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly. - `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages. - `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`. - `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.

This creates an in-memory runtime Plugin, not an installed or configured Plugin. It remains active across later turns until cordis_unmount, toolset unload, or DSH restart. It does not create files, install a package, change cordis.yml or personal/project config, survive restart, or automatically become permanent. To keep it, ask the Agent to implement a normal local, project, or repository Plugin through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime.","parameters":{"type":"object","properties":{"code":{"type":"string","description":"JavaScript body returning a temporary Plugin; evaluated now and saved nowhere."}},"required":["code"]}},{"name":"cordis_unmount","description":"Unmount a current-process temporary Plugin created by cordis_mount.

Keep answers brief and\nfactual.\n\n\nUse the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.\n\nUse the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.\n\nCheck the [exit code: N] marker on every bash result; investigate failures before moving on.\n\nUse a terminal session only when work needs persistent terminal state or interactive stdin; prefer bash/read/write/edit for bounded one-shot operations. Track every terminal session id and close sessions that no longer matter. An inferred_idle or timeout result does not prove the foreground command exited.\n\nTrack every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.\n\nUse the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn.\n\nThe workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

Revisit only if `allow_always` grant storage ever needs machine-checkable scopes.
 - **A generic `env/state` facts map with an owner service** — rejected: approval and sandbox compose independently, so neither's state may drag in a third package; single-key folds are one `findLast` each, dissolving the owner service; no invariant spans the knobs, so atomic multi-key patches bought nothing.

The absence decision is superseded by [the current-policy decision](2026-07-30-current-sandbox-policy-context.md); this measurement and causal observation remain the evidence that any replacement must counter-test.

 - **The approval narrator's restart baseline parses prompt prose.** The closed candidate sentence is owned by the writing module itself, so a wording change is a coordinated writer+parser edit in one file; a session whose headers predate the section silently adopts the current policy without a notice.

 `dsh-sandbox-policy`, the owner of mode and workspace-root resolution, registers one `sandbox:policy` system-prompt section. Every agent request resolves the active session directly through `ctx.sandboxPolicy.resolve({ session })`; there is no denial-history scan, delta narrator, or in-memory “last told” state.
 
-The section states the current file-effect mode and only its owned consequences. `read-only` says ordinary writes, edits, and file-mutating shell effects are denied while required sinks may remain writable. `workspace-write` lists the canonical writable roots returned by the shared `writableRoots()` policy: the immutable session workspace root, `/tmp`, and the platform temporary directory, deduplicated after canonicalization. `danger-full-access` says the DSH file sandbox adds no file restriction. Every form says host permissions or backend availability may restrict more and that network and process access are outside this policy.
+Enforcing backends register independently disposable `filesystem`, `bash`, or `terminal` family contributions with the policy owner. The section names only registered families in canonical order, and is empty without one. This is current need, not a future extension: the shipped headless inheritance composition combines sandboxed filesystem tools with unfenced one-shot bash, while the persistent-tools composition combines sandboxed filesystem tools and terminal commands without a sandboxed one-shot bash executor. A blanket statement would be false in both.
+
+The section states only facts shared by every enforcement dialect for each registered family. `read-only` says those operations cannot modify files. `workspace-write` states the canonical session workspace with non-exclusive wording and summarizes, without enumerating, that some platform temporary areas may also be writable. `danger-full-access` says the DSH file sandbox does not restrict those operations. Backend-selected temporary paths, `/dev/null`, runner readiness, and other policy domains are absent because `resolve()` cannot establish them at request assembly.
 
 The provider runs during normal request assembly, after a `/permission` switch has committed its existing `sandbox/mode` event and before `request/header` is logged. The rendered system text is therefore the durable reconstruction of the exact model-visible fact. Repeated assemblies over unchanged session state produce identical bytes; resume and replay fold the same durable mode event and immutable `SessionHeader.cwd` without catch-up state.
 
-Ownership stays narrow. Approval policy remains the separate `approval:policy` section, plan mode remains `plan:policy`, and tool plugins continue to own schemas and operation guidance. The prompt states policy; bash and filesystem backends remain the enforcement boundaries.

 **Repeat tool schemas or approval and plan guidance in the section.** Rejected because those surfaces already have owners and independent lifecycles. Duplicating them would create contradictory request prefixes and broaden invalidation.
 
-**Keep sandbox mode absent because a standing mode label once caused preemptive refusal.** Rejected by the later Web evidence and the completed cross-family policy. The earlier sentence named only a bash sandbox and did not explain the actual write/edit boundary, so it could conflict with visible tools and escalation guidance. The owner-derived section states the complete current file-effect consequence, canonical workspace scope, and explicit non-guarantees without duplicating tool instructions. This supersedes only the absence decision in the [sandbox Agent Note](2026-07-06-sandbox.md); its enforcement and escalation boundaries remain current.
+**Keep sandbox mode absent because a standing mode label once caused preemptive refusal.** Rejected because a fresh Web request otherwise exposes mutation tools while withholding their standing policy, producing false capability claims before the first operation. The earlier live measurement remains a required counter-test: five of twelve turns ended without a tool call under `Bash commands run under the "read-only" file sandbox.` The committed tool-owned attempt guidance postdates that measurement, so the replacement is selected through a new positive-control experiment under the current tool contract rather than assuming the old and current conditions match.
+
+**A separate model-context package.** Rejected because Cordis services can observe current runtime contributions directly, while approval and plan policy sections already live with their owners. A new package would add a shallow composition seam and documentation/gate surface for one internal adapter.
+
+**Enumerate writable temporary roots.** Rejected because the backend is selected later at `confine()`: bwrap, Landlock, Seatbelt, and the in-process filesystem fence do not grant one common temporary-path set. Host-specific paths in a standing request would be both unstable and overclaimed.
 
 ## Consequences
 
-A model can answer what file effects are currently possible before probing a tool, and the next request after `/permission` reflects the committed mode. This adds a small dynamic system section and intentionally invalidates the request prefix when policy changes; unchanged state remains cache-stable. The statement is guidance, not an enforcement guard: runtime safety still comes from `dsh-bash-sandbox` and `dsh-fs-sandbox` consuming the same resolved policy.

The statement is guidance, not an enforcement guard: runtime safety still comes from the registered filesystem, one-shot bash, and terminal backends consuming the same resolved policy.
 
-Focused sandbox-policy tests pin all three texts, canonical roots, switch timing, byte stability, and replay. A keyless assembled ACP snapshot pins the request header through the real Loader composition, while the Web browser scenario drives `/permission` across all modes, inspects each exact `request/header`, and checks the model completes without a probing tool call; record mode exercises the real provider.
+Focused tests pin all modes, family combinations, contribution disposal, canonical roots, switch timing, and byte stability across different `TMPDIR` values. Keyless assembled snapshots pin the request header through real Loader compositions, including all three families. Real-provider selection uses pre-registered behavioral endpoints to choose wording, while keyless replay owns the selected denial-to-escalation trajectory.

+强制执行后端会向策略归属方注册可独立释放的 `filesystem`、`bash` 或 `terminal` 家族贡献。该段落只按规范顺序列出已注册家族，没有家族时为空。这是当前需求，而不是未来扩展：已交付的 headless inheritance 组合将沙箱化文件系统工具与不受围栏约束的一次性 bash 结合，而 persistent-tools 组合则包含沙箱化文件系统工具与终端命令，却没有沙箱化的一次性 bash 执行器。笼统声明在这两种组合中都会失实。

+该段落只说明每个已注册家族的所有强制执行方言所共有的事实。`read-only` 表明这些操作无法修改文件。`workspace-write` 用非排他措辞说明规范化的会话工作区，并概述某些平台临时区域可能也可写，而不逐一列举。`danger-full-access` 表明 DSH 文件沙箱不会限制这些操作。后端选择的临时路径、`/dev/null`、runner 就绪状态和其他策略领域都不会出现，因为 `resolve()` 无法在请求组装时确定它们。
 
 提供方在正常请求组装期间运行：此时 `/permission` 切换已经提交既有 `sandbox/mode` 事件，`request/header` 尚未记录。因此，渲染后的系统文本就是模型所见确切事实的持久化重建结果。会话状态不变时，重复组装会产生完全相同的字节；恢复与回放会折叠同一条持久模式事件和不可变的 `SessionHeader.cwd`，无需追赶状态。

 **在该段落中重复工具 schema，或批准与计划引导。** 不予采用，因为这些接口已有各自归属方和独立生命周期。重复内容会造成相互矛盾的请求前缀，并扩大缓存失效范围。
 
-**继续省略沙箱模式，因为常驻模式标签曾引发预防性拒绝。** 后续 Web 证据与已经完成的跨工具族策略否决了这一方案。先前的句子只提到 bash 沙箱，没有说明实际的写入／编辑边界，因此可能与可见工具和升级引导冲突。由归属方派生的段落会说明完整的当前文件操作后果、规范化的工作区范围，并明确说明不作哪些保证，同时不重复工具指令。这只取代[沙箱 Agent Note](2026-07-06-sandbox.md) 中关于省略策略的决策；其中的强制执行与升级边界仍然有效。
+**继续省略沙箱模式，因为常驻模式标签曾引发预防性拒绝。** 不予采用，因为新的 Web 请求否则会暴露变更工具，却隐去这些工具的常驻策略，导致模型在首次操作前错误声称自身能力。先前的线上测量仍是必须执行的反证测试：使用 `Bash commands run under the "read-only" file sandbox.` 时，十二个轮次中有五个没有调用工具。已提交的工具归属方尝试引导晚于该测量，因此应通过当前工具契约下的新阳性对照实验选择替代文案，而不能假设旧条件与当前条件相同。

 ## 后果
 
-模型可以在试探工具前回答当前可能执行哪些文件操作，且 `/permission` 后的下一个请求会反映已提交的模式。这会增加一个小型动态系统段落，并在策略变化时有意使请求前缀缓存失效；状态不变时仍保持缓存稳定。该声明是引导，而不是强制执行护栏：运行时安全仍来自 `dsh-bash-sandbox` 与 `dsh-fs-sandbox` 消费同一项解析完成的策略。

 - **Denials are result facts.** A failed run whose stderr carries the selected backend's own denial dialect — the signatures the provider stamps on every wrap (EROFS text under bwrap, EACCES under Landlock, EPERM under Seatbelt) — is reported as `BashRunResult.sandbox.denied: true` (conservative classification, read from the collected stderr tail); every CONFINED run also carries the mode it executed under (`result.sandbox.mode`) and the provider's enforcement completeness (`result.sandbox.enforcement`: `full`, or `partial` on an older Landlock ABI).
 - **Runner failures are sandbox failures, never command failures.** Foreground execution throws `SANDBOX_UNAVAILABLE`; a settled background process stamps `process.sandbox.runnerFailed`, which the bash producer renders through generic `task_output`. Spawn failures also pass through settlement, so confined background handles retain their mode/enforcement facts and release per-process accounting.
-- **Deployment fallback, per-call policy.** [`ctx.sandboxPolicy`](../../sandbox/sandbox-policy/) resolves a complete `SandboxExecutionPolicy` for every tool call: the calling session supplies its mode override and immutable cwd root, while deployment config supplies the fallbacks for agentless calls. An approved escalation changes only that policy's mode; its session root stays attached. `resolve()` carries the policy onto the spec, so overlapping commands from different projects run, classify, and report under their own roots and modes. The capability fact `ctx.bash.sandboxMode` reports the configured default so the tool layer advertises escalation only when this executor is mounted. The model learns of the sandbox only through result facts — the static bash tool description explains the denial marker; there is no current-mode statement in the system prompt.

 - Process mechanics (spawn, process-group kills, output collection/spill, background handles, credential scrub) are inherited from [`dsh-bash-local`](../bash-local/); runner selection lives in [`dsh-sandbox-local`](../../sandbox/sandbox-local/).

 ## Why a shared home
 
-Two families enforce the same mode vocabulary: the sandboxed bash executor (`@deepseek-ai/dsh-bash-sandbox`) and the sandboxed filesystem provider (`@deepseek-ai/dsh-fs-sandbox`). If each resolved its own `mode` + `workspaceRoot`, the two could drift into a split world — bash confined to one root while fs fences another, exactly what [the sandbox RFC](../../../.agents/notes/implemented/feature/2026-07-06-sandbox.md) warns against. Both tool layers resolve policy through `ctx.sandboxPolicy`, and both enforcing backends consume that complete per-call result. The [cross-family fs sandbox RFC](../../../.agents/notes/implemented/feature/2026-07-14-cross-family-fs-sandbox.md) records the shared-policy decision.
+Filesystem tools, one-shot bash commands, and terminal sessions may enforce the same mode vocabulary in different combinations. If each resolved its own `mode` + `workspaceRoot`, they could drift into a split world, exactly what [the sandbox Agent Note](../../../.agents/notes/implemented/feature/2026-07-06-sandbox.md) warns against. Each enforcing backend consumes the complete owner-resolved policy and contributes its model-facing family; the current section therefore does not claim that an unfenced family shares another family's restrictions.

Subject: [PATCH 069/557] test(snapshot): re-record cordis-inspect golden for
 the search card tag

The widened ToolResultView (adding SearchResultView and its member types) shows
in the tools API type surface that cordis_inspect reports, so the
cordis-inspect-jsdoc golden shifts. No other scenario renders a search result
body, so no other snapshot changes. Refreshed keyless.

 Ownership stays narrow. Approval policy remains the separate `approval:policy` section, plan mode remains `plan:policy`, and tool plugins continue to own schemas plus attempt, denial, and escalation guidance. The prompt states standing policy; filesystem, one-shot bash, and terminal backends remain the enforcement boundaries.
 
+## Wording evidence
+
+The wording experiment pre-registered preemptive refusal as its primary endpoint and required the old standing sentence to produce at least one refusal in twelve fresh sessions before any replacement could be judged. On 2026-07-30, commit `2bf41990401b194bd8637f07bbd90c67a9eeac75` ran `deepseek-v4-flash` through the shipped Web composition with the exact positive-control sentence `Bash commands run under the "read-only" file sandbox.` and the current tool-owned attempt guidance. The control produced zero preemptive refusals and zero speculative escalations; all twelve sessions made an ordinary bash call, observed a denial, escalated in the same turn, received approval, and landed the requested file. No sample was excluded.
+
+The positive control therefore failed the pre-registered sensitivity gate. Candidate A and B were not run, and this experiment does not select or validate the current wording. It instead establishes that the earlier five-of-twelve result is not reproducible under this task and current tool guidance, and that a stronger positive control or different task distribution is required before making model-behavior rate claims. Deterministic tests below establish truthful request construction and replay only.
+
 ## Alternatives considered
 
 **Narrate only mode changes.** Rejected because it leaves a fresh session uninformed and makes the first denied operation the policy-discovery mechanism. It also requires a baseline definition that is unnecessary when current state can be rendered directly.

 A model can answer what registered file operations the standing mode governs before probing a tool, and the next request after `/permission` reflects the committed mode. This adds a small dynamic system section and intentionally invalidates the request prefix when policy or enforcing-family composition changes; unchanged state remains cache-stable. The statement is guidance, not an enforcement guard: runtime safety still comes from the registered filesystem, one-shot bash, and terminal backends consuming the same resolved policy.
 
-Focused tests pin all modes, family combinations, contribution disposal, canonical roots, switch timing, and byte stability across different `TMPDIR` values. Keyless assembled snapshots pin the request header through real Loader compositions, including all three families. Real-provider selection uses pre-registered behavioral endpoints to choose wording, while keyless replay owns the selected denial-to-escalation trajectory.

 归属范围保持收敛。批准策略仍由独立的 `approval:policy` 段落负责，计划模式仍由 `plan:policy` 负责，工具插件也继续负责各自的 schema，以及尝试、拒绝与升级引导。提示词负责说明常驻策略；文件系统、一次性 bash 与终端后端仍是强制执行边界。
 
+## 措辞证据
+
+措辞实验预先登记「预防性拒绝」为主要终点，并要求旧常驻句子在十二个 fresh session 中至少产生一次拒绝，之后才能评判任何替代措辞。2026-07-30，commit `2bf41990401b194bd8637f07bbd90c67a9eeac75` 通过已交付的 Web 组合运行 `deepseek-v4-flash`，使用精确的阳性对照句子 `Bash commands run under the "read-only" file sandbox.` 与当前工具归属方的尝试引导。对照组产生零次预防性拒绝和零次推测性升级；十二个会话全部先发起普通 bash 调用、观察到拒绝、在同一轮次升级、获得批准，并让所请求文件实际落盘。没有样本被排除。
+
+因此，阳性对照未通过预先登记的灵敏度门槛。Candidate A 与 B 均未运行，本实验不选择也不验证当前措辞。它只说明先前十二次中五次的结果无法在本任务与当前工具引导下复现；在声明模型行为率之前，需要更强的阳性对照或不同的任务分布。下述确定性测试只证明请求构造与回放真实一致。

 ## 曾考虑的替代方案
 
 **仅叙述模式变更。** 不予采用，因为这会让新会话不了解策略，并把首次被拒绝的操作变成策略发现机制。如果可以直接渲染当前状态，也就无需额外定义基线。

 模型可以在试探工具前回答常驻模式管辖哪些已注册文件操作，且 `/permission` 后的下一个请求会反映已提交的模式。这会增加一个小型动态系统段落，并在策略或强制执行家族组合变化时有意使请求前缀缓存失效；状态不变时仍保持缓存稳定。该声明是引导，而不是强制执行护栏：运行时安全仍来自已注册的文件系统、一次性 bash 与终端后端消费同一项解析完成的策略。

Load when creating stateful agents, durable workflows, real-time WebSocket apps, scheduled tasks, MCP servers, chat applications, voice agents, or browser automation. Covers Agent class, state management, callable RPC, Workflows, durable execution, queues, retries, observability, and React hooks. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.\n- `aico-pm-user-story-writing`: Transform requirements into well-structured User Stories using \"As a [user], I want [goal], So that [benefit]\" format with Given/When/Then acceptance criteria. Use this skill when: - User asks to \"write user story\", \"create story\", \"add story\" - User mentions \"user story\", \"backlog item\", \"story\" - Running /pm.plan and need to break PRD into implementable stories - Creating backlog items for development team - Need to formalize a requirement into standard story format - Converting feature req...\n- `algorithmic-art`: Creating algorithmic art using p5.js with seeded randomness and interactive parameter exploration. Use this when users request creating art using code, generative art, algorithmic art, flow fields, or particle systems. Create original algorithmic art rather than copying existing artists' work to avoid copyright violations.\n- `animation-vocabulary`: Reverse-lookup glossary that turns a vague description of a web animation or motion effect into its exact term (\"the bouncy thing when a popover opens\" → Pop in; \"the iOS rubber-band scroll\" → Rubber-banding). Use when the user asks \"what's it called when…\", or describes a motion effect without knowing its name and wants the right word to prompt an AI or designer with. For naming an effect, not designing or building one.\n- `app-comprehensive-test-generator`: Generate exhaustive user-flow and edge-case test scenarios from an app's codebase, produce scenario .md files, execute tests using connected or newly created MCPs, and produce an app.qa.report.md summarizing failures and suggested fixes.\n- `apple-design`: Apple's approach to interface design and fluid, physical motion, translated for the web. Use when building or reviewing gesture-driven UI, spring animations, drag/swipe/sheet interactions, momentum and interruptible transitions, translucent materials and depth, typography (optical sizing, tracking, leading), reduced-motion, or the design foundations (feedback, spatial consistency, restraint) behind Apple-style interfaces.\n- `brainstorming`: You MUST use this before any creative work - creating features, building components, adding functionality, or modifying behavior. Explores user intent, requirements and design before implementation.\n- `brand-guidelines`: Applies Anthropic's official brand colors and typography to any sort of artifact that may benefit from having Anthropic's look-and-feel. Use it when brand colors or style guidelines, visual formatting, or company design standards apply.\n- `canvas-design`: Create beautiful visual art in .png and .pdf documents using design philosophy. You should use this skill when the user asks to create a poster, piece of art, design, or other static piece. Create original visual designs, never copying existing artists' work to avoid copyright violations.\n- `claude-api`: Reference for the Claude API / Anthropic SDK — model ids, pricing, params, streaming, tool use, MCP, agents, caching, token counting, model migration. TRIGGER — read BEFORE opening the target file; don't skip because it \"looks like a one-liner\" — whenever: the prompt names Claude/Anthropic in any form (Claude, Anthropic, Fable, Opus, Sonnet, Haiku, `anthropic`, `@anthropic-ai`, `claude-*`, `us.anthropic.*`, `[1m]`); the user asks about an LLM (pricing/model choice/limits/caching) — never answ...\n- `cloudflare`: Comprehensive Cloudflare platform skill covering Workers, Pages, storage (KV, D1, R2), AI (Workers AI, Vectorize, Agents SDK), feature flags (Flagship), networking (Tunnel, Spectrum), security (WAF, DDoS), and infrastructure-as-code (Terraform, Pulumi). Use for any Cloudflare development task. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.\n- `cloudflare-email-service`: Send and receive transactional emails with Cloudflare Email Service (Email Sending + Email Routing). Use when building email sending (Workers binding or REST API), email routing, Agents SDK email handling, or integrating email into any app — Workers, Node.js, Python, Go, etc. Also use for email deliverability, SPF/DKIM/DMARC, wrangler email setup, MCP email tools, or when a coding agent needs to send emails. Even for simple requests like \"add email to my Worker\" — this skill has critical conf...\n- `cloudflare-one`: Guides Cloudflare One Zero Trust and SASE work across Access, Gateway, WARP, Tunnel, Cloudflare WAN, DLP, CASB, device posture, and identity. Use when designing, configuring, troubleshooting, or reviewing Cloudflare One deployments. Retrieval-first: use current Cloudflare docs/API schemas instead of embedded product docs.\n- `cloudflare-one-migrations`: Plans migrations from Zscaler ZIA/ZPA, Palo Alto, legacy VPN, SWG, or SASE stacks to Cloudflare One. Use for migration assessments, policy mapping, rollout plans, and parity/gap analysis.\n- `code-review`: Review the changes since a fixed point (commit, branch, tag, or merge-base) along two axes — Standards (does the code follow this repo's documented coding standards?) and Spec (does the code match what the originating issue/PRD asked for?). Runs both reviews in parallel sub-agents and reports them side by side. Use when the user wants to review a branch, a PR, work-in-progress changes, or asks to \"review since X\".\n- `codebase-design`: Shared vocabulary for designing deep modules. Use when the user wants to design or improve a module's interface, find deepening opportunities, decide where a seam goes, make code more testable or AI-navigable, or when another skill needs the deep-module vocabulary.\n- `content-refiner`: Refine verbose educational content by eliminating redundancy, tightening prose, and strengthening lesson connections. Use when content is wordy, repetitive, or lacks narrative flow between sections.\n- `context-compression`: This skill should be used when long-running agent sessions need context compression, structured summarization, compaction, token-per-task optimization, or durable handoff summaries that preserve decisions, files, risks, and next actions.\n- `create-feishu-doc`: Create a Feishu document and grant edit permissions to the user. Use when asked to write content to Feishu or create a document in a wiki space.\n- `design-compass`: Use when doing any product or UI design work — brainstorming a feature, starting a visual/interaction direction, reviewing half-built UI, or final-checking before ship; also when unsure which design skill applies. 产品设计 / 界面设计 / 交互设计 / UI review / 脑暴 / 视觉方向 / 设计验收时使用。\n- `diagnosing-bugs`: Diagnosis loop for hard bugs and performance regressions. Use when the user says \"diagnose\"/\"debug this\", or reports something broken/throwing/failing/slow.\n- `doc-coauthoring`: Guide users through a structured workflow for co-authoring documentation. Use when user wants to write documentation, proposals, technical specs, decision docs, or similar structured content. This workflow helps users efficiently transfer context, refine content through iteration, and verify the doc works for readers. Trigger when user mentions writing docs, creating proposals, drafting specs, or similar documentation tasks.\n- `docx`: Comprehensive document creation, editing, and analysis with support for tracked changes, comments, formatting preservation, and text extraction. When Claude needs to work with professional documents (.docx files) for: (1) Creating new documents, (2) Modifying or editing content, (3) Working with tracked changes, (4) Adding comments, or any other document tasks\n- `domain-modeling`: Build and sharpen a project's domain model. Use when the user wants to pin down domain terminology or a ubiquitous language, record an architectural decision, or when another skill needs to maintain the domain model.\n- `durable-objects`: Create and review Cloudflare Durable Objects.

Use when the user asks to \"orient me in this project\", \"what is this repo about\", or \"build a context map for this paper\" — and the project already has .research/ manifests (or trigger research-context-compressor first).\n- `research-report`: 将deep调研结果汇总为markdown报告，覆盖所有字段，跳过不确定值。\n- `research-session-management`: Use when starting or ending any thesis writing session — manages INDEX files, handoff documents, and startup/shutdown protocols for cross-session continuity. Triggers on 'new thesis session', 'session handoff', 'continue thesis work', 'pick up where left off', 'end session'.\n- `research-style-audit`: Use after completing any thesis section draft — runs programmatic style audit to catch Pattern\n- `research-task-file`: Use when creating self-contained task files for autonomous AI agent execution — goal-oriented instructions with context, decision frameworks, and validation criteria. Triggers on 'create task file', 'autonomous task', 'agent task', 'data extraction task', 'TASK file', 'batch processing task'.\n- `research-three-stage-review`: Use after completing a thesis prose draft — runs three independent review stages with different perspectives and information access. Triggers on 'review draft', 'check section', 'draft review', 'quality check', 'before sending to advisor'.\n- `research-writing`: Use when starting any academic thesis or dissertation writing task — routes to the correct thesis sub-skill based on the current phase of work. Triggers on 'thesis', 'dissertation', 'chapter writing', 'section writing', 'defense prep', 'academic writing with AI'.\n- `research-writing-brief`: Use when planning any thesis section before writing prose — creates a Writing Brief with boundary rules, internalization check, verified data table, and paragraph-level outline with argumentative purposes. Triggers on 'plan section', 'write section X.Y', 'prepare to write', 'writing brief', 'section outline'.\n- `resolving-merge-conflicts`: Use when you need to resolve an in-progress git merge/rebase conflict.\n- `sandbox-sdk`: Build sandboxed applications for secure code execution. Load when building AI code execution, code interpreters, CI/CD systems, interactive dev environments, or executing untrusted code. Covers Sandbox SDK lifecycle, commands, files, code interpreter, and preview URLs. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.\n- `scheduled-task-planner`: 分析定时任务需求，确定最优部署方案（Cloudflare Worker 或本地 launchd）\n- `sequential-thinking`: Structured reflective problem-solving methodology. Process: decompose, analyze, hypothesize, verify, revise. Capabilities: complex problem decomposition, adaptive planning, course correction, hypothesis verification, multi-step analysis. Actions: decompose, analyze, plan, revise, verify solutions step-by-step. Keywords: sequential thinking, problem decomposition, multi-step analysis, hypothesis verification, adaptive planning, course correction, reflective thinking, step-by-step, thought sequ...\n- `skill-creator`: Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, edit, or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.\n- `slack-gif-creator`: Knowledge and utilities for creating animated GIFs optimized for Slack. Provides constraints, validation tools, and animation concepts. Use when users request animated GIFs for Slack like \"make me a GIF of X doing Y for Slack.\"\n- `tdd`: Test-driven development. Use when the user wants to build features or fix bugs test-first, mentions \"red-green-refactor\", or wants integration tests.\n- `test`: Test features before users find bugs. Use when feature is built, before deploying, or when bugs reported. Covers manual testing, edge cases, cross-browser testing, and testing checklists for non-technical founders.\n- `theme-factory`: Toolkit for styling artifacts with a theme. These artifacts can be slides, docs, reportings, HTML landing pages, etc. There are 10 pre-set themes with colors/fonts that you can apply to any artifact that has been creating, or can generate a new theme on-the-fly.\n- `turnstile-spin`: Set up Cloudflare Turnstile end-to-end in a project — scan the codebase, create the widget via the Cloudflare API, deploy the managed siteverify Worker, write the frontend snippets, validate, and persist the skill. Load this when a user asks to add Turnstile, set up CAPTCHA, protect a form from bots, or fix a Turnstile integration. Mirrors developers.cloudflare.com/turnstile/spin.\n- `web-artifacts-builder`: Suite of tools for creating elaborate, multi-component claude.ai HTML artifacts using modern frontend web technologies (React, Tailwind CSS, shadcn/ui). Use for complex artifacts requiring state management, routing, or shadcn/ui components - not for simple single-file HTML/JSX artifacts.\n- `web-perf`: Analyzes web performance using Chrome DevTools MCP. Measures Core Web Vitals (LCP, INP, CLS) and supplementary metrics (FCP, TBT, Speed Index), identifies render-blocking resources, network dependency chains, layout shifts, caching issues, and accessibility gaps.

Load before running wrangler commands to ensure correct syntax and best practices. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.\n- `xlsx`: Use this skill any time a spreadsheet file is the primary input or output. This means any task where the user wants to: open, read, edit, or fix an existing .xlsx, .xlsm, .csv, or .tsv file (e.g., adding columns, computing formulas, formatting, charting, cleaning messy data); create a new spreadsheet from scratch or from other data sources; or convert between tabular file formats. Trigger especially when the user references a spreadsheet file by name or path — even casually (like \"the xlsx in...\n- `zotero-library-curator`: Audit and curate a Zotero library — find duplicate DOIs, orphan items missing required tags, propose collection rebinds, identify bloated or under-used collections, generate tag hygiene reports, emit preview-only cleanup plans. Use when the user asks to \"audit Zotero\", \"find duplicates\", \"tag hygiene report\", \"which collections are bloated or under-used\", or \"propose a Zotero cleanup plan\". Defers all CRUD operations to the standalone `zotero-skills` skill or `research-hub zotero` CLI. Includ...\n\n\nIf the user names a skill, or the task clearly matches a skill's description, call the `skill` tool with the exact skill name before taking task actions. Load all applicable skills, then follow their full instructions.

Subject: [PATCH 078/557] fix(web-read-card): align highlight grammars with
 read hints, fix fixture schema, restore running sweep

Register the full grammar set the read tool's langFromPath emits (python,
go, rust, yaml, markdown, html, and the rest) so a read card highlights the
same extensions the backend recognizes instead of returning undefined for
them. Rewrite highlightLines' terminator-line check to the explicit
last !== undefined form to keep a single branch for per-file coverage.

Add the running-state sweep animation to ReadRow, matching BashRow/ToolRow,
so a running read row shows executing feedback.

Use file_path (the real read tool schema field) in the turn 66 read fixture
sample, its presentCall branch, and the turn 64 run_code read sub-dispatches,
so the built-boot snapshot replays a production-shaped call and the details
panel shows the correct Input JSON.

Document why ReadBlock omits TerminalBlock's empty-window copy guard, and
correct the read-card-model {@link} and the turn 66 fixture comment.

to it crossed ground belonging to neither. The row action menus put
closeOnPointerLeave's handler on the portaled list, so aiming back at the
... trigger that opened it, or overshooting a list edge, closed it with no
window to come back.

usePointerGrace owns one cancelable delayed close (200ms) shared by both
atoms: leaving arms it, returning cancels it. The hover card becomes
hit-testable so resting on it holds it open, and Menu moves pointer-leave
dismissal to the wrapper span, where React's enter/leave traversal makes
trigger and portaled list one region.

Both gestures are pinned in the real browser lane; each fails without the
corresponding fix.

+# Agent Note: Hover popup pointer grace
+
+Status: implemented
+
+English | [中文](2026-07-30-hover-popup-pointer-grace.zh.md)
+
+## Problem
+
+Both popups the workspace browser rows raise floated out of reach of the pointer. `HoverCard` closed on the first `pointerleave` from its anchor and rendered its card `pointer-events: none`, but the card sits 8px off the anchor's right edge, so every path to it crossed ground belonging to neither and killed the card before it arrived — the full workspace path and session title it exists to show could be read only in passing. The row action menus passed `closeOnPointerLeave`, whose handler sat on the portaled list: aiming back at the `...` trigger that opened the list closed it, and so did any overshoot past a list edge, with no window to come back.
+
+## Decision
+
+`usePointerGrace` ([packages/client/ui-primitives/src/pointer-grace.ts](../../../../packages/client/ui-primitives/src/pointer-grace.ts)) owns one cancelable delayed close, shared by both atoms, with `POINTER_GRACE_MS` at 200. Leaving arms the close; coming back cancels it. Transit through an anchor-to-popup gap is therefore survivable, while a pointer that has genuinely moved on still dismisses the popup.
+
+`HoverCard` arms the grace on leave instead of closing, and its card no longer sets `pointer-events: none`, so resting on the card holds it open. Re-entering while already open cancels the pending close without restarting the dwell, which keeps the card from blinking when the pointer crosses the gap. A press inside the anchor and an owner flipping `disabled` still dismiss immediately, ahead of the grace.
+
+`Menu` moves pointer-leave dismissal from the portaled list to the wrapper span. React's enter/leave traversal runs over the React tree, so the trigger and the portaled list are one region there: crossing the 4px gap between them, or aiming back at the trigger, no longer counts as leaving. Leaving is only armed while the list is open, and an owner-driven close (selection, Escape, outside click) disarms a pending grace close in an effect keyed on `open` alone — folding that into the outside-click effect would cancel the grace on every re-render, since owners pass a fresh `onClose` closure each time.
+
+## Alternatives considered
+
+**Close the popups only on outside click and Escape.** Rejected because both popups are hover-raised and unlabeled as dismissible; leaving them up after the pointer has moved to another row would strand a card over unrelated content.
+
+**Widen the anchor's hit area to abut the popup.** Rejected because the 8px and 4px offsets are the design's, and an invisible bridge element would have to track every reposition the fixed-positioned popups already do on scroll and resize.
+
+**Keep the hover card `pointer-events: none` and only add the grace.** Rejected because the pointer resting on the card would then hit whatever is behind it, so the grace would expire and close the card the user had just reached.
+
+**Give each atom its own timer.** Rejected because the two closes are the same behavior with the same tuning; a shared hook keeps them from drifting apart.
+
+## Consequences
+
+The hover card is now hit-testable and covers 244px of whatever it overlays while shown, which is the price of being reachable; it still lives only as long as the pointer is on the row or the card. Row menus survive the round trip between trigger and list, and a menu that closes for its own reason cannot be reopened into a stale pending close. Menus without `closeOnPointerLeave` are untouched — the wrapper handlers are only attached when it is set.
+
+## Testing
+
+`packages/client/ui-primitives/tests/hover-card.spec.tsx` and `tests/atoms.spec.tsx` pin the grace boundary, cancel-on-return, no-second-dwell, disarm-on-owner-close, and the no-arming-while-closed case. The reachability gestures themselves — hovering onto the card, and moving between an open list and its trigger — are pinned in the real browser by `apps/web/tests/workspace-management.e2e.ts`, since they depend on hit testing and layout that jsdom does not model.

+# Agent Note: 悬浮弹层的指针宽限期
+
+Status: implemented
+
+[English](2026-07-30-hover-popup-pointer-grace.md) | 中文
+
+## 问题
+
+工作区浏览器行弹出的两种弹层都处于指针无法抵达的位置。`HoverCard` 在指针离开锚点的第一个 `pointerleave` 上就关闭，其卡片还设置了 `pointer-events: none`；但卡片位于锚点右边缘外 8px 处，因此通往卡片的每条路径都要穿过既不属于锚点也不属于卡片的区域，卡片在指针抵达之前就已被销毁——它本应展示的完整工作区路径和会话标题只能匆匆一瞥。行操作菜单传入了 `closeOnPointerLeave`，而其处理器挂在传送后的列表上：把指针移回打开该列表的 `...` 触发按钮会关闭列表，越过列表边缘的任何一次抖动同样如此，且没有任何折返窗口。
+
+## 决策
+
+`usePointerGrace`（[packages/client/ui-primitives/src/pointer-grace.ts](../../../../packages/client/ui-primitives/src/pointer-grace.ts)）持有唯一一个可取消的延迟关闭，由两个原子组件共享，`POINTER_GRACE_MS` 为 200。离开会启动关闭，折返则取消它。因此指针可以安全穿越锚点与弹层之间的间隙，而真正移开的指针仍会关闭弹层。
+
+`HoverCard` 在离开时启动宽限期而不再立即关闭，其卡片也不再设置 `pointer-events: none`，因此指针停在卡片上即可让它保持打开。在已打开状态下重新进入只取消待执行的关闭，而不重启停留计时，从而避免指针穿越间隙时卡片闪烁。在锚点内按下指针以及所有者将 `disabled` 置真，仍会抢在宽限期之前立即关闭卡片。
+
+`Menu` 把指针离开关闭的处理从传送后的列表移到包裹 span 上。React 的 enter/leave 遍历基于 React 树进行，因此触发按钮与传送后的列表在这里属于同一区域：穿越两者之间 4px 的间隙、或把指针移回触发按钮，都不再算作离开。只有在列表打开时才会启动离开关闭；由所有者驱动的关闭（选择、Escape、外部点击）会在一个仅以 `open` 为依赖的 effect 中解除待执行的宽限关闭——若把它折叠进外部点击的 effect，则每次重新渲染都会取消宽限期，因为所有者每次都传入新的 `onClose` 闭包。
+
+## 考虑过的替代方案
+
+**仅通过外部点击和 Escape 关闭这两种弹层。** 之所以否决：两者都由悬停唤起，且没有可见的关闭标识；在指针已移到其他行之后仍让它们停留，会把卡片遗留在无关内容之上。
+
+**扩大锚点的命中区域，使其与弹层相接。** 之所以否决：8px 与 4px 的偏移来自设计稿，而一个不可见的桥接元素还必须跟随这两个固定定位弹层已经在滚动和缩放时执行的每一次重新定位。
+
+**保留悬浮卡片的 `pointer-events: none`，只加入宽限期。** 之所以否决：那样指针停在卡片上时命中的是卡片背后的元素，宽限期仍会到期，并关闭用户刚刚够到的卡片。
+
+**让两个原子组件各自持有计时器。** 之所以否决：这两处关闭是同一种行为、同一套调参；共享 hook 可以防止它们各自漂移。
+
+## 后果
+
+悬浮卡片现在可被命中，显示期间会遮挡其覆盖区域的 244px——这是可抵达性的代价；它依然只在指针位于行或卡片上时存在。行菜单现在能承受触发按钮与列表之间的往返，而因自身原因关闭的菜单也不会被残留的待执行关闭重新关掉。未设置 `closeOnPointerLeave` 的菜单不受影响——只有设置该属性时才会挂上包裹层处理器。
+
+## 测试
+
+`packages/client/ui-primitives/tests/hover-card.spec.tsx` 与 `tests/atoms.spec.tsx` 固定验证宽限期边界、折返取消、不重启停留计时、所有者关闭时解除待执行关闭，以及列表关闭时不启动关闭。可抵达性手势本身——把指针移到卡片上，以及在打开的列表与其触发按钮之间移动——由 `apps/web/tests/workspace-management.e2e.ts` 在真实浏览器中固定验证，因为它们依赖 jsdom 无法建模的命中测试与布局。

A run-state `StateDot` marks the call once, on the first row, out of flow in a gutter the card reserves as its own left padding, so the dot sits inside the card box yet left of the prompt text. It reaches three of `StateDot`'s states — the chase while `running`, red for the same exit status that renders the pill, green otherwise — so a card states whether its command is still running rather than leaving that to be inferred from the presence of output; it carries one visually hidden text label because `StateDot` is `aria-hidden`. One dot regardless of line count is deliberate: the exit status is the whole call's, so a dot per line would claim a per-line outcome the view does not carry. Command text is `white-space: pre`, so repeated spaces, tabs, and an indented continuation render verbatim while the row stays single-line and ellipsizes. ANSI escape sequences are parsed with the `anser` runtime dependency into React spans; cursor movements replay into a per-line column buffer before inert controls are stripped, since carriage return and backspace only MOVE the cursor: `100%` + CR + `OK` alone shows `OK0%`, while the `\x1b[K` a spinner writes with its redraw erases the tail so `100%\r\x1b[KOK` shows `OK`. Erase-in-line is honored in all three parameter forms, the cursor advances by terminal columns (8-column tab stops, two for emoji and CJK, none for a combining mark), and SGR state is normalized per cell as a terminal stores it, threading across lines and closing at the state the line ended in; basic-16 foreground colors map onto `--dsw-*` tokens, while 256-palette and truecolor values pass through as literal rgb. Output keeps `white-space: pre` with horizontal scrolling, so column-aligned output holds its alignment instead of soft-wrapping, and collapses to a head slice plus a tail slice past `maxLines` (default 16, the TUI transcript's split arithmetic) behind an expand button. Rationale: [the web terminal card note](../../../.agents/notes/implemented/feature/2026-07-28-web-terminal-card.md). +## Search results + +`SearchBlock` renders a completed search, one component for both kinds (discriminated by `kind`). A `matches` (grep) shows each file as a bold path header with its `lineNumber: line` rows, the per-file group collapsible; a `paths` (glob) shows a flat path list. Both flatten to one row list the height cap slices head/tail over (default 16, the TerminalBlock split arithmetic), and neither soft-wraps — a long match line or path scrolls horizontally instead of folding.

The read card's `langFromPath` hints span the full source/config/markup extension set (python, rust, yaml, html, …); registering all of them eagerly would add ~1.6 MB of grammar modules to the boot chunk and their synchronous init to every session, including sessions that never open a read card. So only the three grammars every session already renders — TypeScript, shell, JSON (the markdown-fence and `run_code` languages) — load at boot. Each read-card extension grammar sits behind a dynamic `import()` in `LAZY_GRAMMARS`, keyed by the grammar id its aliases resolve to. On the first `highlightLines`/`highlightToHtml` call for a lazy language, `ensureGrammar` starts the import (once) and returns not-ready, so the card renders plain that frame; when the import resolves it registers the grammar with `loadLanguageSync`, bumps a load counter, and notifies subscribers. `ReadBlock` and `CodeBlock` subscribe through `useSyncExternalStore(subscribeGrammarLoaded, grammarLoadCount)`, so the card re-renders with highlighting the moment the grammar is ready. An unknown/absent language still returns undefined synchronously (plain, never an error). + +**The empty-window copy control is hidden, matching `TerminalBlock`.** A successful read of an empty file returns `lines: []`, `totalLines: 0`, and `presentResult` still projects `card: 'read'`, so the empty-window branch is reachable — the read card is not, as an earlier draft assumed, unreachable for an empty result. `ReadBlock` therefore hides the copy control when `lines` is empty, exactly as `TerminalBlock` hides copy on empty output, so the button can never wipe the clipboard with an empty string. + ## Alternatives considered **Extend `CodeBlock` with an optional line-number gutter and `startLine`.** Rejected: it imposes a read-specific gutter, a windowed-count note, and a height cap on every markdown fence and `run_code` body that shares `CodeBlock`, for no benefit to those callers. The genuinely shared surface is the shiki grammar singleton, which both blocks reuse through `highlight.ts`; the chrome around it differs (a read has a gutter and a window note, a fence has neither), so a second small primitive is the correct split, exactly as `TerminalBlock` is a second primitive over the same tokens rather than a `CodeBlock` mode. **Reuse `highlightToHtml` and inject gutter numbers with CSS counters.** Rejected: the single-`
` HTML shiki emits has no per-line boundary a gutter can hang a file line number off (a windowed read's numbers start above 1 and are not a simple CSS counter increment), and parsing the numbers back out of the HTML would be fragile. `codeToTokens` gives the per-line token structure directly.
 
+**Register all read-card grammars eagerly in the boot warm-up.** Rejected: it puts ~1.6 MB of grammar modules and their synchronous init on every Web boot for a card most sessions never open. The lazy path costs a single plain-first frame the first time a given language is read, then highlights on the grammar-load re-render; the boot cost is paid only for the three grammars every session already renders.
+
 ## Consequences
 
 `ui-primitives` gains `ReadBlock` and `highlightLines`; no new runtime dependency (shiki was already present for `CodeBlock`). `ReadBlock` reads only the read view's fields, so it stays a pure function of what the render intent carries — no session lookups, replay-safe like the presenters that produce the view. A UI without the read capability still gets the backend's `content` fallback (the envelope-stripped text) through the generic card, unchanged.

Both `ReadBlock.tsx` and `highlight.ts` (and `CodeBlock.tsx`) hold per-file 100% coverage across the two specs.
 
 `packages/client/ui-conversation/tests/read-card.spec.tsx` pins the wiring at every render site: `readCardModel`'s derivation and each null arm (running read, no view, generic view, unknown card), the result title replacing the relativized path, the path relativization against the workspace, the copy-not-alias of the frozen line array; the resident card in `GenericToolCard`'s fallback and in the keyed `ReadRow` (plus its path link opening the host, its running/error/stopped states, and its `read`-key registration); and the panel's Output section rendering the read card at full height while keeping the JSON Input section, with the running-read placeholder and non-read flattened-pre arms. That file sits on the coverage `exclude` list (`ui-conversation/src/*`), so it is written against no gate pressure.

It is named `read` to exercise the keyed `ReadRow`; the render-site fallback row is already covered by the read sub-dispatches in the turn 64 `run_code` sample.

+**读取卡片的语法按需 lazy 加载，只有 boot 三种保持 eager。** `highlight.ts` 是 `ui-primitives` 在每次 Web 启动都加载的平台 seed，其预热会无条件构建 shiki 单例。读取卡片的 `langFromPath` 提示覆盖完整的源码/配置/标记扩展集（python、rust、yaml、html……）；把它们全部 eager 注册会给启动 chunk 增加约 1.6 MB 的语法模块、并把它们的同步初始化摊给每个会话，包括从不打开读取卡片的会话。因此只有每个会话本就渲染的三种语法 —— TypeScript、shell、JSON（markdown 围栏与 `run_code` 语言）—— 在 boot 时加载。每种读取卡片扩展语法置于 `LAZY_GRAMMARS` 中一个动态 `import()` 之后，以其别名解析到的语法 id 为键。对某个 lazy 语言首次调用 `highlightLines`/`highlightToHtml` 时，`ensureGrammar` 启动 import（仅一次）并返回未就绪，于是卡片该帧渲染纯文本；import 解析后用 `loadLanguageSync` 注册该语法、递增一个加载计数、并通知订阅者。`ReadBlock` 与 `CodeBlock` 通过 `useSyncExternalStore(subscribeGrammarLoaded, grammarLoadCount)` 订阅，因此语法就绪的那一刻卡片就重渲染带上高亮。未知/缺省语言仍同步返回 undefined（纯文本，绝不报错）。
+
+**空窗口的复制控件被隐藏，与 `TerminalBlock` 对齐。** 成功读取一个空文件会返回 `lines: []`、`totalLines: 0`，且 `presentResult` 仍投出 `card: 'read'`，因此空窗口分支是可达的 —— 读取卡片并非如早前草稿所假设的对空结果不可达。故 `ReadBlock` 在 `lines` 为空时隐藏复制控件，正如 `TerminalBlock` 对空输出隐藏复制，使按钮绝不会用空字符串清空剪贴板。

 ## Alternatives considered
 
 **给 `CodeBlock` 加一个可选行号栏和 `startLine`。** 拒绝：这会把读取专属的行号栏、窗口计数提示和高度上限强加给共享 `CodeBlock` 的每个 markdown 围栏和 `run_code` 程序体，对那些调用者毫无好处。真正共享的界面是 shiki 语法单例，两个 block 都通过 `highlight.ts` 复用它；围绕它的外壳各不相同（读取有行号栏和窗口提示，围栏两者都没有），因此第二个小 primitive 是正确的切分 —— 正如 `TerminalBlock` 是基于同一套 token 的第二个 primitive，而不是 `CodeBlock` 的一种模式。
 
 **复用 `highlightToHtml`，用 CSS counter 注入行号。** 拒绝：shiki 产出的单 `
` HTML 没有可供行号栏挂上文件行号的逐行边界（窗口读取的行号从大于 1 处开始，不是简单的 CSS counter 自增），而从 HTML 里把行号解析回来又很脆弱。`codeToTokens` 直接给出逐行 token 结构。
 
+**在 boot 预热里 eager 注册所有读取卡片语法。** 拒绝：这会给每次 Web 启动摊上约 1.6 MB 语法模块及其同步初始化，只为一张多数会话从不打开的卡片。lazy 路径的代价是某个语言首次被读取时的一帧纯文本，随后在语法加载的重渲染里高亮；boot 代价只为每个会话本就渲染的三种语法付出。

 `ui-primitives` 增加 `ReadBlock` 和 `highlightLines`；没有新的运行时依赖（shiki 已因 `CodeBlock` 存在）。`ReadBlock` 只读取读取视图的字段，因此保持为渲染意图所承载内容的纯函数 —— 无会话查询，与产出该视图的 presenter 一样可安全回放。没有读取能力的 UI 仍通过通用卡片拿到后端的 `content` 回退（剥掉外壳的文本），保持不变。

Subject: [PATCH 085/557] fix(web-read-card): align read spec with real schema
 and correct grammar docs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Top-level read samples in read-card.spec use the read tool's real file_path
schema key (web_fetch keeps its own path key); the Input-JSON assertion follows.
The LANGS/LANG_ALIASES JSDoc no longer claims the TypeScript grammar embeds
JSX/TSX — shiki's TS grammar tokenizes JSX approximately, an accepted trade to
keep one JS-family boot grammar.

Subject: [PATCH 086/557] refactor(fs): minimize and cap search card meta; keep
 TUI byte-identical

Address the review of the search render card:

- The search result view carries no `content`: it was a no-op for every
  consumer and serialized the whole search text twice. A UI without a search
  card falls back to the raw tool/result content; the TUI stays byte-identical
  to the pre-search-card generic fallback.
- Bound the serialized presentationMeta with a configurable searchMetaMaxBytes
  (default 64 KiB): the inline item cap does not bound bytes, and spill-policy
  only shrinks content, never meta. capMetaBytes drops trailing groups/paths.
- Share one retention pass (retainGrepMatches/retainGlobPaths in search-core)
  between the model-facing render and the meta projection; remove the second
  cap/preview implementation and the presentation<->grep module cycle by
  moving GrepMatch/previewLine to search-core.
- Rename the result-view discriminant kind -> shape so it no longer collides
  with GenericCallView.kind (ToolCallKind, whose values include 'search').
- Narrow the entry export surface to consumed symbols.
- Sync the three bilingual ToolResultView doc pairs and the Agent Note pair;
  document the deliberate empty-card acceptance vs diffsFromMeta.
- Regenerate config/tool/cordis catalogs for the new config field.

 ## Problem
 
-`grep` and `glob` return structured canonical values — `grep` a flat `{ matches: [{ path, lineNumber, line }] }`, `glob` a `{ paths: string[] }` — but every UI only ever saw their model-facing render text: `grep` groups its matches under file headers with `Line N:` rows, `glob` prints a newline-joined path list, and both append a spill footer when the inline cap ({@link module:@deepseek-ai/dsh-tool-fs-search/grep} `grepMaxMatches`, default 250; {@link module:@deepseek-ai/dsh-tool-fs-search/glob} `globMaxResults`, default 100) drops later results to a spill file. A web frontend that wants to render a search result as an expandable per-file group of matches, or as a selectable path list, had to re-parse that text. Both tools already declared a call-time [render intent](../architecture/2026-07-02-tool-render-intent-union.md) (`GenericCallView`, `kind: 'search'`) but no result-time view, so the completed call fell back to the generic card that renders the raw text.

 The structured canonical value does not cross the wire: only the model-facing render text and, when a tool declares `output.presentationMeta`, a JSON metadata payload reach the client, threaded through the `tool/result` event ([canonical-output contract](../architecture/2026-07-20-canonical-tool-output-contract.md)). A result-time view carrying structured data therefore has to project that data into `presentationMeta` and read it back in `presentResult` — the same path `write`/`edit` use for their diff cards.
 
 ## Decision
 
-`packages/core/tools/src/presentation.ts` adds `card: 'search'` to the `ToolResultView` union as `SearchResultView`, a `kind`-discriminated view that expresses both tools' shapes: `SearchMatchesResultView` (`kind: 'matches'`) carries `grep`'s matches grouped by file as `files: { path, matches: { lineNumber, line }[] }[]`, and `SearchPathsResultView` (`kind: 'paths'`) carries `glob`'s flat `paths: string[]`. Both carry `truncated: boolean` and `total: number`, and an optional `content?: ContentBlock[]`.
+`packages/core/tools/src/presentation.ts` adds `card: 'search'` to the `ToolResultView` union as `SearchResultView`, a `shape`-discriminated view that expresses both tools' shapes: `SearchMatchesResultView` (`shape: 'matches'`) carries `grep`'s matches grouped by file as `files: { path, matches: { lineNumber, line }[] }[]`, and `SearchPathsResultView` (`shape: 'paths'`) carries `glob`'s flat `paths: string[]`. Both carry `truncated: boolean` and `total: number`.
 
-One view with two shapes rather than two cards, because both tools are the same visual object — a search result — and a web consumer switches on one `card` value, then on `kind` for the row shape. The discriminated `kind` keeps each shape's fields non-optional (a matches view always has `files`, a paths view always has `paths`) instead of a single interface where every shape-specific field is optional.
+The discriminant is `shape`, not `kind`, deliberately: the same presentation module already gives `GenericCallView` a `kind: ToolCallKind` field whose values include `'search'` (the icon category). A bridge holding a `ToolCallView | ToolResultView` would see two `kind` fields with two meanings; `shape` for the result variant keeps the two apart.
+
+One view with two shapes rather than two cards, because both tools are the same visual object — a search result — and a web consumer switches on one `card` value, then on `shape` for the row layout. The discriminated `shape` keeps each variant's fields non-optional (a matches view always has `files`, a paths view always has `paths`) instead of a single interface where every shape-specific field is optional.
+
+The view carries **no** result text. An earlier revision attached the model-facing `result.content` to the view; that was a no-op for every consumer (the TUI already falls back to `result.content`, and web fallbacks read the raw `tool/result` content), and it serialized the whole search text a second time into the persisted view. The view is the structured shape only; a UI without a search card falls back to the raw `tool/result` content.
 
 The card tag is result-time only. A search call stays a `GenericCallView` (`kind: 'search'`): the pending state has no matches or paths to show, so there is nothing a `SearchCallView` would carry that the generic title does not. This is the asymmetry with the terminal card, whose call view carries the command, cwd, and description that exist before execution; a search's structured content exists only after `execute`.
 
-`packages/fs/tool-fs-search/src/presentation.ts` owns the projection and the narrowing. `grepSearchMeta`/`globSearchMeta` project the canonical value into a `SearchMeta` payload each tool declares as `output.presentationMeta`; `presentGrepResult`/`presentGlobResult` read `result.meta` back through `searchViewFromMeta` and attach the model-facing `result.content` as the view's `content`. The projections apply the SAME inline cap and per-line preview budget the model-facing render applies, and report `total` as every result the search found (before capping) with `truncated` set when the cap dropped results. This is the truncation-honesty point: the model saw a capped inline result plus a spill footer, so the card must not present the retained page as the complete result — a UI reads `truncated`/`total` to show a capped indicator rather than claiming completeness the model never had.
+`packages/fs/tool-fs-search/src/presentation.ts` owns the projection and the narrowing. `grepSearchMeta`/`globSearchMeta` project the canonical value into a `SearchMeta` payload each tool declares as `output.presentationMeta`; `presentGrepResult`/`presentGlobResult` read `result.meta` back through `searchViewFromMeta`. They consume the SAME retained result the model-facing render consumes — `retainGrepMatches`/`retainGlobPaths` in `search-core.ts` run the inline cap and per-line preview budget ONCE, and both the render and the projection take that outcome — so text and card never disagree about which results survived, and there is no second retention pass. `total` is every result the search found (before capping); `truncated` is set when the cap dropped results. This is the truncation-honesty point: the model saw a capped inline result plus a spill footer, so the card must not present the retained page as the complete result — a UI reads `truncated`/`total` to show a capped indicator rather than claiming completeness the model never had.
 
-`searchViewFromMeta` narrows the opaque `meta` defensively and returns `undefined` on any malformed or absent payload, exactly as `diffsFromMeta` does, so a presenter run on an older or hand-edited replayed log falls back to the generic card instead of throwing. `presentResult` returns `undefined` for a failed result, for absent meta (a nested `run_code` dispatch computes no `presentationMeta`), and for the other tool's meta shape (each presenter narrows to its own `kind`).
+**The meta has its own byte budget.** The inline cap bounds the item COUNT, but the retained matches of a broad search (hundreds of long lines) can still serialize to hundreds of kilobytes, and `meta` is persisted with the session log and re-sent on every request. A deployment's final output budget (`dsh-spill-policy`, `maxInlineBytes`) only shrinks a result's `content` — `PostToolDecision` has no `meta` channel — so the projection owns keeping `meta` bounded. `capMetaBytes` drops trailing file groups / paths until the serialized meta fits `searchMetaMaxBytes` (config, default 64 KiB) and marks the result `truncated`. A single item too large to fit on its own is kept: the invariant is a bounded payload wherever droppable, never an empty card that hides a real result.
 
-The `SearchMeta` member shapes are object-literal `type` aliases, not the `SearchFileMatches`/`SearchLineMatch` interfaces the view exposes. Only a type alias is assignable to the `JsonValue` index signature `presentationMeta` returns; the two are structurally identical, so the projected value still reads back as a `SearchResultView`.
+`searchViewFromMeta` narrows the opaque `meta` defensively and returns `undefined` on any malformed or absent payload, so a presenter run on an older or hand-edited replayed log falls back to the generic card instead of throwing. It DOES accept a zero-result payload (`files: []` / `paths: []`) as a valid empty card — this is a deliberate departure from the mirrored `diffsFromMeta`, which rejects empty `diffs`, because a zero-match grep is a legitimate result a UI shows as "no matches", not an absent projection. `presentResult` returns `undefined` for a failed result, for absent meta (a nested `run_code` dispatch computes no `presentationMeta`), and for the other tool's meta shape (each presenter narrows to its own `shape`).
 
-The TUI (`packages/ui/tui/src/components/transcript.ts`) needs no dedicated arm: its result-view switch handles `terminal` and `diff` explicitly and falls through to a generic arm that renders `view.content ?? this.result?.content`. Because `SearchResultView` carries the model-facing text as `content`, the TUI renders it as the same text it already showed. The web frontend that renders the structured `files`/`paths` shape is a separate later PR; this PR is the backend contract and its two producers.

+The TUI (`packages/ui/tui/src/components/transcript.ts`) needs no dedicated arm: its result-view switch handles `terminal` and `diff` explicitly, and a `search` view falls through to the same dim generic body, reading the model-facing text from `this.result?.content`.

 ## Alternatives considered
 
-**A single flat `SearchResultView` interface with optional `files?` and `paths?`.** Rejected: it makes both shape-specific fields optional on every value and lets a malformed view carry both or neither. The `kind` discriminant keeps each shape's fields required and lets a consumer switch exhaustively.
+**A single flat `SearchResultView` interface with optional `files?` and `paths?`.** Rejected: it makes both shape-specific fields optional on every value and lets a malformed view carry both or neither. The `shape` discriminant keeps each variant's fields required and lets a consumer switch exhaustively.
 
-**A call-time `SearchCallView` mirroring the terminal card's both-sides symmetry.** Rejected: a search call has no matches or paths before `execute`, so the view would carry only the title the `GenericCallView` already carries. The terminal card's call view earns its tag because a command, cwd, and description exist at call time; a search's structured content does not.
+**Reuse `kind` as the shape discriminant.** Rejected: `kind` already means `ToolCallKind` (the icon category, whose values include `'search'`) on the call view in the same module. A second `kind` with a different meaning on the result view collides for any bridge holding both.
 
-**Carry the structured result in a bespoke channel instead of `presentationMeta`.** Rejected: the canonical value is execution-local and never reaches the client, and `presentationMeta` is the established seam that persists a tool's JSON presentation payload with `tool/result` and threads it back to `presentResult`. Adding a second channel would duplicate that path.
+**Attach the model-facing text as the view's `content`.** Rejected: a no-op for every current consumer and a second serialization of the whole search text into the persisted view. The view is the structured shape; text fallback reads the raw result content.
+
+**A meta channel on `PostToolDecision` so `dsh-spill-policy` bounds `meta` like it bounds `content`.** Rejected for this PR: it changes the core tool decision contract and the spill-policy plugin for one tool's payload. The projection bounding its own `meta` at a config byte cap is self-contained and keeps the seam unchanged.
+
+**A call-time `SearchCallView` mirroring the terminal card's both-sides symmetry.** Rejected: a search call has no matches or paths before `execute`, so the view would carry only the title the `GenericCallView` already carries.
 
 ## Consequences
 
-`grep` and `glob` now compute `presentationMeta` on every non-nested successful call, a bounded projection over the already-parsed matches or paths. The projection re-applies the retention cap the render already applied, so the retained set is computed twice per call; the input is bounded by the raw-output cap, so this is not a new scaling concern.
+`grep` and `glob` now compute `presentationMeta` on every non-nested successful call, a bounded projection over the already-retained matches or paths — the same retention outcome the render consumes, so there is no second retention pass and no doubled search text on the wire. The serialized meta is bounded by `searchMetaMaxBytes`, so a broad search no longer persists an unbounded structured copy into the session log.
 
-A UI without a search card renders the attached `content` text, so no consumer regresses. The web consumer that renders the structured shape reads `truncated`/`total` and the per-file groups; because the view carries only the retained page, a UI wanting the complete result follows the spill locator in the model-facing text, exactly as the model does.

 ## Testing
 
-`packages/fs/tool-fs-search/tests/presentation.spec.ts` pins the pure layer: `groupMatchesByFile`'s first-seen file order, `grepSearchMeta`/`globSearchMeta` projection with the cap applied and `total` reporting the pre-cap count, the per-line preview budget on a projected match line, and `searchViewFromMeta`'s narrowing of both good shapes plus every malformed case (non-object/array meta, missing or mistyped `truncated`/`total`, unknown `kind`, malformed `files` entries, non-string `paths`). `packages/fs/tool-fs-search/tests/tools.spec.ts` pins the wiring through the real tool registry: a capped `grep`/`glob` execute produces the `SearchMeta` on `result.meta` and `presentResult` builds the search view with `content` attached, a nested `run_code` dispatch computes no meta so `presentResult` falls back, and a failed or cross-shape or malformed result falls back to the generic card. Per-file 100% coverage holds over the search package `src`.

-## Problem
+## 问题
 
-`grep` 与 `glob` 返回结构化的规范值——`grep` 是扁平的 `{ matches: [{ path, lineNumber, line }] }`，`glob` 是 `{ paths: string[] }`——但每一个 UI 见到的只有它们面向模型的渲染文本：`grep` 把匹配按文件分组，文件头下是 `Line N:` 行；`glob` 打印换行连接的路径列表；当内联上限（{@link module:@deepseek-ai/dsh-tool-fs-search/grep} `grepMaxMatches`，默认 250；{@link module:@deepseek-ai/dsh-tool-fs-search/glob} `globMaxResults`，默认 100）把后续结果溢出到 spill 文件时，两者都追加一段溢出脚注。想把搜索结果渲染成可展开的按文件分组匹配、或渲染成可选择的路径列表的 web 前端，只能去重新解析这段文本。两个工具都已声明了调用期的[渲染意图](../architecture/2026-07-02-tool-render-intent-union.md)（`GenericCallView`，`kind: 'search'`），但没有结果期视图，于是已完成的调用回退到渲染原始文本的通用卡片。

-结构化的规范值不过线：只有面向模型的渲染文本、以及当工具声明 `output.presentationMeta` 时的一段 JSON 元数据抵达客户端，二者通过 `tool/result` 事件穿线（[规范输出契约](../architecture/2026-07-20-canonical-tool-output-contract.md)）。因此携带结构化数据的结果期视图必须把该数据投射进 `presentationMeta`，再在 `presentResult` 里读回——正是 `write`/`edit` 的 diff 卡片所走的路径。
+结构化 canonical 值不跨线传输：只有面向模型的渲染文本、以及当工具声明了 `output.presentationMeta` 时的一份 JSON 元数据，会经 `tool/result` 事件到达客户端（[canonical-output 契约](../architecture/2026-07-20-canonical-tool-output-contract.md)）。因此携带结构化数据的结果时视图必须把数据投影进 `presentationMeta`，再在 `presentResult` 里读回 —— 与 `write`/`edit` 的 diff 卡片走同一条路。
 
-## Decision
+## 决定
 
-`packages/core/tools/src/presentation.ts` 向 `ToolResultView` 联合类型加入 `card: 'search'`，即 `SearchResultView`：一个以 `kind` 区分的视图，表达两个工具的形状。`SearchMatchesResultView`（`kind: 'matches'`）以 `files: { path, matches: { lineNumber, line }[] }[]` 携带 `grep` 按文件分组的匹配；`SearchPathsResultView`（`kind: 'paths'`）携带 `glob` 的扁平 `paths: string[]`。两者都携带 `truncated: boolean` 与 `total: number`，以及可选的 `content?: ContentBlock[]`。
+`packages/core/tools/src/presentation.ts` 把 `card: 'search'` 作为 `SearchResultView` 加入 `ToolResultView` 联合，这是一个以 `shape` 判别的视图，表达两个工具的形状：`SearchMatchesResultView`（`shape: 'matches'`）以 `files: { path, matches: { lineNumber, line }[] }[]` 承载 `grep` 按文件分组的匹配，`SearchPathsResultView`（`shape: 'paths'`）承载 `glob` 的扁平 `paths: string[]`。两者都带 `truncated: boolean` 与 `total: number`。
 
-一个视图两种形状，而非两张卡片，因为两个工具是同一个视觉对象——一个搜索结果——web 消费方先在一个 `card` 值上分派，再在 `kind` 上分派行的形状。区分性的 `kind` 让每种形状各自的字段保持非可选（matches 视图恒有 `files`，paths 视图恒有 `paths`），而不是让所有形状相关字段都变成可选的单一接口。
+判别子是 `shape` 而非 `kind`，是刻意为之：同一个 presentation 模块已经给 `GenericCallView` 一个 `kind: ToolCallKind` 字段，其取值恰好包含 `'search'`（图标类别）。持有 `ToolCallView | ToolResultView` 的桥接层会看到两个含义不同的 `kind` 字段；结果变体用 `shape` 把两者分开。
 
-卡片标签只在结果期。搜索调用仍是 `GenericCallView`（`kind: 'search'`）：pending 状态没有匹配或路径可展示，因此 `SearchCallView` 能携带的东西不会超出通用标题。这是与 terminal 卡片的不对称之处——terminal 的调用视图携带执行前就存在的命令、cwd 与描述；而搜索的结构化内容只在 `execute` 之后才存在。
+用一个带两种形状的视图而非两张卡片，因为两个工具是同一个视觉对象 —— 一个搜索结果 —— web 消费方先在一个 `card` 值上分支，再在 `shape` 上分支决定行布局。判别式 `shape` 让每个变体的字段保持非可选（matches 视图总有 `files`，paths 视图总有 `paths`），而不是一个所有形状相关字段都可选的单一接口。
 
-`packages/fs/tool-fs-search/src/presentation.ts` 拥有投射与收窄。`grepSearchMeta`/`globSearchMeta` 把规范值投射为一段 `SearchMeta`，各工具将其声明为 `output.presentationMeta`；`presentGrepResult`/`presentGlobResult` 通过 `searchViewFromMeta` 把 `result.meta` 读回，并把面向模型的 `result.content` 作为视图的 `content` 附上。投射施加与面向模型渲染相同的内联上限与每行预览预算，并把 `total` 报告为搜索找到的全部结果（截断之前），当上限丢弃了结果时把 `truncated` 置为真。这就是截断诚实性的要点：模型看到的是被截断的内联结果加一段溢出脚注，因此卡片不得把保留的那一页当作完整结果呈现——UI 读取 `truncated`/`total` 去展示截断指示，而非宣称模型从未拥有的完整性。
+该视图**不**携带结果文本。早期版本曾把面向模型的 `result.content` 附到视图上；那对每个消费方都是 no-op（TUI 本就回退到 `result.content`，web 回退读原始 `tool/result` 内容），却把整段搜索文本又序列化进持久化视图一遍。视图只承载结构化形状；无 search 卡片的 UI 回退到原始 `tool/result` 内容。
 
-`searchViewFromMeta` 防御性地收窄不透明的 `meta`，对任何畸形或缺失的 payload 返回 `undefined`，与 `diffsFromMeta` 完全一致，因此在较旧或手工编辑过的回放日志上运行的呈现器会回退到通用卡片而非抛错。`presentResult` 对失败结果、对缺失的 meta（嵌套 `run_code` 分发不计算 `presentationMeta`）、对另一个工具的 meta 形状（每个呈现器只收窄到自己的 `kind`）都返回 `undefined`。
+卡片标签只在结果时存在。搜索调用保持为 `GenericCallView`（`kind: 'search'`）：pending 状态没有匹配或路径可展示，所以 `SearchCallView` 能携带的东西不会比 generic 标题更多。这是与 terminal 卡片的不对称之处 —— terminal 的调用视图携带执行前就存在的命令、cwd、description；搜索的结构化内容只在 `execute` 之后才存在。
 
-`SearchMeta` 的成员形状是对象字面量 `type` 别名，而不是视图对外暴露的 `SearchFileMatches`/`SearchLineMatch` 接口。只有 type 别名可以赋值给 `presentationMeta` 返回的 `JsonValue` 索引签名；二者结构完全相同，因此投射出的值仍能读回为 `SearchResultView`。
+`packages/fs/tool-fs-search/src/presentation.ts` 拥有投影与收窄。`grepSearchMeta`/`globSearchMeta` 把 canonical 值投影为每个工具声明为 `output.presentationMeta` 的 `SearchMeta` 载荷；`presentGrepResult`/`presentGlobResult` 经 `searchViewFromMeta` 把 `result.meta` 读回。它们消费与面向模型渲染相同的已保留结果 —— `search-core.ts` 里的 `retainGrepMatches`/`retainGlobPaths` 只跑一次内联上限与每行预览预算，render 与投影都取这份产出 —— 所以文本与卡片对哪些结果幸存永不分歧，也没有第二次保留计算。`total` 是搜索找到的全部结果（截断前）；`truncated` 在上限丢弃了结果时置位。这是截断诚实点：模型看到的是被截断的内联结果加一个 spill 脚注，所以卡片不能把保留页当作完整结果 —— UI 读 `truncated`/`total` 显示截断指示，而非宣称模型从未有过的完整性。
 
-TUI（`packages/ui/tui/src/components/transcript.ts`）无需专用分支：它的结果视图 switch 显式处理 `terminal` 与 `diff`，并落到一个渲染 `view.content ?? this.result?.content` 的通用分支。因为 `SearchResultView` 以 `content` 携带了面向模型的文本，TUI 渲染出的仍是它此前已展示的同一段文本。渲染结构化 `files`/`paths` 形状的 web 前端是后续独立的 PR；本 PR 是后端契约及其两个生产者。
+**meta 有自己的字节预算。** 内联上限约束的是条目数，但一次宽泛搜索保留下来的匹配（数百条长行）仍可序列化到数百 KB，而 `meta` 会随会话日志持久化并在每次请求时重发。部署的最终输出预算（`dsh-spill-policy` 的 `maxInlineBytes`）只缩减结果的 `content` —— `PostToolDecision` 没有 `meta` 通道 —— 所以投影自己负责把 `meta` 约束住。`capMetaBytes` 丢弃末尾的文件组／路径，直到序列化 meta 装进 `searchMetaMaxBytes`（配置，默认 64 KiB），并把结果标记 `truncated`。单个大到自身都装不下的条目会被保留：不变量是可丢弃处一律有界，绝不产出隐藏了真实结果的空卡片。
 
-## Alternatives considered
+`searchViewFromMeta` 防御性地收窄不透明的 `meta`，对任何畸形或缺失载荷返回 `undefined`，使在较旧或手工编辑的回放日志上运行的 presenter 回退到 generic 卡片而非抛错。它确实接受零结果载荷（`files: []` / `paths: []`）为合法的空卡片 —— 这是与被镜像的 `diffsFromMeta` 的刻意偏离（后者拒绝空 `diffs`），因为零匹配的 grep 是 UI 展示为「no matches」的合法结果，而非缺失的投影。`presentResult` 对失败结果、对缺失 meta（嵌套 `run_code` 分发不计算 `presentationMeta`）、以及对另一工具的 meta 形状（每个 presenter 收窄到自己的 `shape`）返回 `undefined`。
 
-**单一扁平的 `SearchResultView` 接口，带可选的 `files?` 与 `paths?`。** 否决：它让两种形状相关字段在每个值上都成为可选，并允许一个畸形视图同时携带二者或都不携带。`kind` 区分符让每种形状的字段保持必填，并让消费方能穷尽分派。
+`SearchMeta` 的成员形状是对象字面量 `type` 别名，而非视图暴露的 `SearchFileMatches`/`SearchLineMatch` 接口，因为只有 type 别名可赋给 `presentationMeta` 返回的 `JsonValue` 索引签名；两者结构等价，所以投影值仍读回为 `SearchResultView`。
 
-**一个调用期的 `SearchCallView`，镜像 terminal 卡片两侧对称。** 否决：搜索调用在 `execute` 之前没有匹配或路径，视图只会携带 `GenericCallView` 已携带的标题。terminal 卡片的调用视图之所以配得上其标签，是因为命令、cwd 与描述在调用期就存在；而搜索的结构化内容不存在。
+TUI（`packages/ui/tui/src/components/transcript.ts`）不需要专门分支：它的结果视图 switch 显式处理 `terminal` 与 `diff`，`search` 视图落入同一个变暗的 generic body，从 `this.result?.content` 读取面向模型的文本。因为搜索视图不带自己的 `content`，而本 PR 之前 grep/glob 返回的是 generic 卡片，所以 TUI 输出与无 search 卡片的回退逐字节一致。渲染结构化 `files`/`paths` 形状的 web 前端是另一个后续 PR；本 PR 是后端契约及其两个生产者。
 
-**用一个专门的通道而非 `presentationMeta` 携带结构化结果。** 否决：规范值是执行局部的、绝不抵达客户端，而 `presentationMeta` 是既有的接缝，它把工具的 JSON 呈现 payload 随 `tool/result` 持久化并穿线回 `presentResult`。再加一条通道只会重复这条路径。
+## 考虑过的备选
 
-## Consequences
+**一个扁平的 `SearchResultView` 接口，带可选 `files?` 与 `paths?`。** 否决：它让两个形状相关字段在每个值上都可选，并允许畸形视图同时带两者或都不带。`shape` 判别式让每个变体的字段保持必需，并让消费方穷尽分支。
 
-`grep` 与 `glob` 现在在每次非嵌套的成功调用上计算 `presentationMeta`，这是对已解析的匹配或路径做的一次有界投射。投射重新施加渲染已施加过的保留上限，因此每次调用会计算两遍保留集；输入受原始输出上限约束，故这不是新的伸缩性问题。
+**复用 `kind` 作形状判别子。** 否决：同一模块里调用视图上的 `kind` 已经表示 `ToolCallKind`（图标类别，取值含 `'search'`）。结果视图上再有一个含义不同的 `kind`，对任何同时持有两者的桥接层都会冲突。
 
-没有搜索卡片的 UI 渲染附上的 `content` 文本，因此没有消费方回退。渲染结构化形状的 web 消费方读取 `truncated`/`total` 与按文件分组；因为视图只携带保留的那一页，想要完整结果的 UI 沿面向模型文本里的 spill 定位符去取，与模型的做法完全一致。
+**把面向模型的文本作为视图的 `content` 附上。** 否决：对每个当前消费方是 no-op，且把整段搜索文本第二次序列化进持久化视图。视图是结构化形状；文本回退读原始结果内容。
 
-## Testing
+**在 `PostToolDecision` 上加 meta 通道，让 `dsh-spill-policy` 像约束 `content` 那样约束 `meta`。** 本 PR 否决：它为一个工具的载荷改动核心工具决策契约与 spill-policy 插件。投影在配置字节上限处约束自己的 `meta` 是自包含的，且保持 seam 不变。
 
-`packages/fs/tool-fs-search/tests/presentation.spec.ts` 钉住纯函数层：`groupMatchesByFile` 的首见文件顺序，`grepSearchMeta`/`globSearchMeta` 施加上限后的投射与把 `total` 报告为截断前计数，投射出的匹配行上的每行预览预算，以及 `searchViewFromMeta` 对两种良态形状的收窄外加所有畸形情形（非对象/数组 meta、缺失或类型错误的 `truncated`/`total`、未知 `kind`、畸形 `files` 条目、非字符串 `paths`）。`packages/fs/tool-fs-search/tests/tools.spec.ts` 通过真实工具注册表钉住穿线：一次被截断的 `grep`/`glob` execute 在 `result.meta` 上产出 `SearchMeta`，且 `presentResult` 构建出附带 `content` 的搜索视图；嵌套 `run_code` 分发不计算 meta 于是 `presentResult` 回退；失败、跨形状或畸形结果回退到通用卡片。搜索包 `src` 上维持逐文件 100% 覆盖。
+**镜像 terminal 卡片双侧对称的调用时 `SearchCallView`。** 否决：搜索调用在 `execute` 前没有匹配或路径，视图只会携带 `GenericCallView` 已有的标题。

 How a tool wants its call shown in a UI (an editor tool-call card, a CLI log line), provider-neutral so a tool describes itself without depending on any client protocol. `presentCall`/`presentResult` return a **`card`-tagged render intent** — a discriminated union a UI bridge switches on:
 
 - `ToolCallView` (pending): `{ card: 'generic', title, kind?, rawInput?, content?, locations? }` (the default card; `locations` is `{ path, line? }[]` files the call reads/modifies, for editor follow-along), `{ card: 'terminal', title, description?, cwd? }` (a shell command → a terminal card), or `{ card: 'diff', title, diffs, locations? }` (a file create/modify → an inline diff card; `diffs` is `{ path, oldText, newText }[]`, `oldText: null` for a new file).
-- `ToolResultView` (completed): `{ card: 'generic', title?, content? }`, `{ card: 'terminal', title?, output?, exitCode?, signal? }` (the captured run output + exit; a capable UI shows an exit-status pill, while another may derive a fenced ` ```console ` fallback), or `{ card: 'diff', title?, diffs }` (a completed file mutation → the change to show, typically the applied hunks with context lines computed from the before/after content, or a whole-file diff when there is no before-image).

Completed views replace pending views, so mutation tools return a diff result even when it duplicates the call-time snippet; a search has no `card: 'search'` call-time analogue (its pending state stays a generic card, since matches exist only after `execute`).
 
 `ToolCallKind` (`'read' | 'edit' | 'delete' | 'move' | 'search' | 'execute' | 'fetch' | 'other'`) picks an icon on a generic card. `FileLocation` (`{ path, line? }`) and `FileDiff` (`{ path, oldText, newText }`) are the shared file-card vocabulary. The design is pinned in [the render-intent-union Agent Note](../../.agents/notes/implemented/architecture/2026-07-02-tool-render-intent-union.md); the TUI and host/client runtime project this neutral vocabulary into their own views.

 - `ToolCallView`（待执行）：`{ card: 'generic', title, kind?, rawInput?, content?, locations? }`（默认卡片；`locations` 是 `{ path, line? }[]`，表示调用读取/修改的文件，供编辑器跟随）、`{ card: 'terminal', title, description?, cwd? }`（shell 命令→终端卡片）、或 `{ card: 'diff', title, diffs, locations? }`（文件创建/修改→行内 diff 卡片；`diffs` 是 `{ path, oldText, newText }[]`，新文件时 `oldText: null`）。

 Tools optionally own pure `presentCall()` and `presentResult()` render intents, so UIs do not special-case tool names:

 Returning `undefined` selects generic fallback. Presenters depend only on their arguments and the durable result because UIs call them during live streaming and log replay. `output.presentationMeta(args, value)` derives JSON metadata for direct surface calls; that metadata persists with `tool/result` and returns to `presentResult`, while the canonical value itself remains execution-local and is never replayed. Nested Code dispatches do not compute metadata. `defineTool` soft-validates older logged arguments and falls back instead of crashing replay. `dsh-tool-bash` and `dsh-tool-fs` are the reference implementations; the [canonical-output Agent Note](../../../.agents/notes/implemented/architecture/2026-07-20-canonical-tool-output-contract.md) owns the value/presentation split and the [render-intent Agent Note](../../../.agents/notes/implemented/architecture/2026-07-02-tool-render-intent-union.md) owns card vocabulary.

 The browser client is fixed separately, in [the web transcript projection note](2026-07-30-web-transcript-log-ordered-projection.md): it projects the same append-origin transcript in log order and renders a marker component, and it closes the pagination hole this change opened — because `session.history` no longer spends quota on the checkpoint, it never cuts on the checkpoint's provenance group, so a page can carry a checkpoint citing a `surfaceOp.start` outside the window, which the browser's surface fold rejected. That hole predates this change (counting could already run past a checkpoint into the range it shadows), but the old rule accidentally covered the case where the checkpoint was the oldest counted message and pulled the whole shadowed range onto its page.
 
-Rendering compaction *progress* — a terminal indicator while a compaction runs — needs the bracket-first ordering that the queued manual `/compact` work introduces, and is out of scope here. The marker also carries no scale: the checkpoint's `sourceEventSeqs` already hold the shadowed count, so a count or range would tell a reader how much each row folded. That belongs with progress, where the reader meets the other half of the same information. Whoever takes it should fold the terminal's two replacement branches — replay and the live listener, textually identical and 600 lines apart — into one `renderReplacement(event)` first, so the marker's content has a single home.
+The terminal's [live compaction progress decision](../feature/2026-07-30-compaction-progress-visibility.md) uses standalone bracket events to drive the existing one-cell indicator. It does not change the completion marker owned here or add scale: the checkpoint's `sourceEventSeqs` remain available for a separately justified count or range. Progress therefore needs neither marker-content changes nor a prerequisite `renderReplacement(event)` extraction.

+# Agent Note: Live standalone compaction progress in the terminal
+
+Status: implemented
+
+English | [中文](2026-07-30-compaction-progress-visibility.zh.md)
+
+## Problem
+
+A standalone manual compaction runs between turns while the agent remains idle. The TUI's turn-phase indicator therefore kept its plain `>` caret throughout the slow summary operation, and a failed attempt produced no transcript row because no replacement checkpoint landed.
+
+The durable log can retain an unmatched `compact/start` after a process dies. That orphan is useful recovery evidence, but it is not proof that work is running in the current process; replaying it as progress would leave resumed sessions with a permanent phantom indicator.
+
+## Decision
+
+The TUI treats the live standalone `compact/start { turn: null }` to matching `compact/end` bracket as the source of in-flight compaction presentation. A module-local `compacting` cell records the render-clock start and owns one animation timer. The existing one-cell indicator renders `⊙` through the same fade and throb path as turn-phase glyphs, and the terminal progress bit remains active until the bracket closes.
+
+Turn-phase glyphs take precedence over `⊙`. Numbered compaction brackets are ignored because they are enclosed by a running turn whose phase already lights the indicator. The compaction cell does not change the idle editor border, hint, or steering badge, so prompts remain visibly accepted while standalone compaction reserves turn admission.
+
+The cell is live-only. Mount and transcript replay never scan history for an unmatched start; only a `session/event` notification observed by the mounted TUI can open it. Turn-status transitions preserve the cell, while terminal teardown clears its timer and progress bit.
+
+On `compact/end`, the TUI clears the live cell before starting the ordinary glyph fade-out. An end carrying `error` adds `Compaction failed: ` as a warning. Successful completion remains represented by the landed replacement's transcript marker, and duration remains derivable from the matching durable start and end timestamps without another visible row.
+
+This decision partially supersedes only the progress-related deferred clauses in the [terminal transcript decision](../bug-fix/2026-07-29-human-transcript-append-origin.md) and [browser transcript decision](../bug-fix/2026-07-30-web-transcript-log-ordered-projection.md): progress does not require marker scale or a replacement-rendering refactor. Both notes remain active and continue to own append-origin transcript projection and landed checkpoint markers. The [queued manual compaction decision](2026-07-30-queued-manual-compaction.md) remains the owner of bracket ordering, locking, and stale-orphan classification.
+
+## Alternatives considered
+
+**Add `progressLabel` to `CommandDefinition` and a second TUI status controller, as explored in PR #669.** Rejected because command metadata is not the compaction lifecycle authority, automatic compaction does not originate from a human command, and two status controllers can disagree about the same indicator.
+
+**Add `compacting` to `TurnPhase`, as explored in PR #669.** Rejected because standalone compaction deliberately has no turn, while numbered compaction already has a visible running-turn phase.
+
+**Add a fifth `TimingBucket`.** Rejected because timing buckets partition an open model step and feed its transcript footer. Standalone compaction has no step transition, and a new bucket would add a meaningless compaction column to every step total.
+
+**Share one timer among running, fading, and compaction states.** Rejected because fade-out owns a self-terminating timer, while live compaction has an independent open/close lifetime. Sharing would restructure the reviewed animation state machine without removing an actual concurrent timer.
+
+**Scan the log for an unmatched `compact/start`.** Rejected because a stale orphan from an earlier process lifecycle is expected durable history. Only the live notification proves current work.
+
+**Use a generic command-running indicator.** Rejected for this behavior because the compaction bracket is the more precise source and also covers non-command paths. A future generic command indicator belongs to the `command/run` / `command/done` lifecycle.
+
+**Print a success notice with duration.** Rejected because the landed replacement already supplies the completion marker. The bracket timestamps preserve duration for a future presentation that justifies another transcript row.
+
+## Consequences
+
+Manual compaction now has visible liveness while the agent is idle, failure has a direct warning, and a resumed orphan never looks active. The indicator remains one terminal cell wide and reuses the existing animation, color, and terminal-progress behavior.
+
+The live cell and its timer are additional process-local state, cleared on both bracket close and TUI teardown. This is intentionally not reconstructible presentation state: durable history supplies the successful marker and timing facts, while current-process observation alone supplies liveness.
+
+The package-level TUI tests pin standalone start, numbered-start exclusion, fade-out, failure warning, idle-status preservation, running-turn precedence, orphaned resume, and timer disposal. The assembled `queued-manual-compact` terminal scenario also observes `dsh ⊙` while the real summary boundary is held.

+# Agent Note: 终端中的实时独立压缩进度
+
+Status: implemented
+
+[English](2026-07-30-compaction-progress-visibility.md) | 中文
+
+## 问题
+
+独立手动压缩（compaction）在轮次之间运行，此时 agent（智能体）保持空闲。因此，在缓慢的摘要操作期间，TUI 的轮次阶段指示器始终显示普通的 `>` 光标；尝试失败时，由于没有替换检查点落地，也不会产生 transcript（文本记录）行。
+
+进程终止后，持久日志中可能保留未匹配的 `compact/start`。该未匹配标记是有用的恢复证据，但无法证明当前进程中有工作正在运行；若将其回放为进度，恢复后的会话便会永久显示虚假的进度指示。
+
+## 决策
+
+TUI 将实时独立的 `compact/start { turn: null }` 与匹配的 `compact/end` 组成的标记对，作为显示进行中压缩状态的真源。模块局部的 `compacting` 状态记录渲染时钟的起始时间，并独占一个动画定时器。现有的单格指示器通过与轮次阶段字形相同的明暗渐变和呼吸律动路径渲染 `⊙`，终端进度标志位会保持活跃，直至标记对闭合。
+
+轮次阶段字形的优先级高于 `⊙`。带编号的压缩标记对会被忽略，因为它们处于运行中的轮次内，该轮次的阶段已经激活指示器。压缩状态不会改变空闲编辑器边框、提示或 steering（中途引导）徽标，因此，在独立压缩预留轮次准入期间，界面仍会明确显示提示词已获接纳。
+
+该状态只反映实时事件。挂载和 transcript 回放绝不会扫描历史以查找未匹配的 start；只有已挂载的 TUI 观察到 `session/event` 通知，才能开启该状态。轮次状态转换会保留该状态，而终端清理会清除其定时器和进度标志位。
+
+收到 `compact/end` 时，TUI 会先清除实时状态，再启动普通字形的淡出。携带 `error` 的结束事件会以警告形式添加 `Compaction failed: `。成功完成仍由已落地替换项的 transcript 标记呈现；无需再添加可见行，也可从匹配且已持久记录的开始与结束时间戳推导持续时间。
+
+本决策仅部分取代[终端 transcript 决策](../bug-fix/2026-07-29-human-transcript-append-origin.md)和[浏览器 transcript 决策](../bug-fix/2026-07-30-web-transcript-log-ordered-projection.md)中与进度相关的延期条款：进度显示不要求标记携带规模信息，也不要求重构替换项渲染。两份记录均保持活动状态，并继续负责基于追加来源的 transcript 投影和已落地检查点标记。[排队式手动压缩决策](2026-07-30-queued-manual-compaction.md)继续负责标记对顺序、锁定机制和陈旧未匹配标记分类。
+
+## 曾考虑的替代方案
+
+**按照 PR（Pull Request）#669 中探索的方案，为 `CommandDefinition` 添加 `progressLabel` 和第二个 TUI 状态控制器。** 不予采用：命令元数据并非压缩生命周期的权威依据，自动压缩并非由人工命令发起，两个状态控制器也可能对同一个指示器给出不一致状态。
+
+**按照 PR #669 中探索的方案，将 `compacting` 添加到 `TurnPhase`。** 不予采用：独立压缩按设计没有轮次，而带编号的压缩已经具有可见的运行轮次阶段。
+
+**添加第五个 `TimingBucket`。** 不予采用：计时分桶用于划分一个开放模型步骤内的时间，并为其 transcript 页脚提供数据。独立压缩没有步骤转换，新分桶会在每个步骤总计中加入一个没有意义的压缩列。
+
+**让运行、淡出和压缩状态共享一个定时器。** 不予采用：淡出过程独占一个会自行终止的定时器，而实时压缩有独立的开启与闭合生命周期。共享定时器会重构已经评审的动画状态机，却不能消除实际存在的并发定时器。
+
+**扫描日志，查找未匹配的 `compact/start`。** 不予采用：来自先前进程生命周期的陈旧未匹配标记是预期的持久历史。只有实时通知才能证明当前进程正在执行工作。
+
+**使用通用的命令运行指示器。** 本行为不采用该方案，因为压缩标记对是更精确的真源，并且还覆盖非命令路径。未来若实现通用命令指示器，应归属于 `command/run` 和 `command/done` 生命周期。
+
+**打印包含持续时间的成功通知。** 不予采用：已落地的替换项已经提供完成标记。标记对的时间戳保留了持续时间，可供未来能够证明新增 transcript 行合理的展示方式使用。
+
+## 后果
+
+手动压缩在 agent 空闲时会显示正在运行，失败会直接产生警告，恢复会话时的陈旧未匹配标记绝不会显示为活动状态。指示器保持一个终端字符单元宽，并复用现有的动画、颜色和终端进度行为。
+
+实时状态及其定时器是额外的进程局部状态，在标记对闭合和 TUI 清理这两种情况下都会清除。按设计，这种显示状态不可重建：持久历史提供成功标记与计时事实，只有当前进程的观察才能提供运行中状态。
+
+包（package）级 TUI 测试固定了以下行为：独立开始事件、排除带编号的开始事件、淡出、失败警告、保留空闲状态、运行轮次优先级、存在未匹配标记时的恢复，以及定时器释放。组装后的 `queued-manual-compact` 终端场景还会在真实摘要边界保持开放期间观察到 `dsh ⊙`。

 When optional `ctx.sessionReferences` is mounted, the same `@` menu also offers metadata-only session candidates, inserts `@[label](dsh-session:)`, and prepares the selected snapshots before dispatch. Session references remain structured because the model has no filesystem-like tool for retrieving session snapshots later. Preparation disables duplicate submission and restores the editor input on failure. The TUI chooses `agent.steer()` or `agent.followup()` from the status after that asynchronous preparation, so idle follow-ups still dispatch `agent/prompt-submit` while in-turn steering joins at a checkpoint without that hook.
 
-While the agent is running, ordinary editor submissions call `agent.steer()`; otherwise they call `agent.followup()`. A slash at the start of the submitted line enters `ctx.commands` instead: known commands execute directly, unknown commands produce a warning, and neither path automatically reaches the model. A command producer may explicitly schedule agent work; [`dsh-plan-mode`](../../plan/plan-mode/README.md#model-and-human-surfaces) uses that contract for `/plan [message]`. The TUI registers `/help`, `/model`, `/clear`, `/palette`, `/reload`, `/resume`, `/status`, and `/exit` as agent-scoped definitions; every other effective command joins autocomplete and `/help` dynamically, as do `/skill:` completions. A status line above the editor reports the turn phase the TUI derives from session events — waiting for the first token, thinking, responding, or executing tools — with the elapsed time in that phase and the running step total, refreshed each second, and ends with the `Enter sends steering, Esc cancels` hint; while steering messages wait to reach the model it inserts a `N queued ·` badge before the hint that clears as each drains. Ctrl+C or Escape cancels a running turn. Tool and injected-context cards collapse long bodies into a configurable head/tail preview; Ctrl+O cycles tool cards through collapsed preview, full output, and hidden — the hidden phase drops tool cards from the transcript entirely while context cards stay at their preview, since injected instructions are not tool traffic. An injected-context card renders its message as prose with the producer's outer reminder frame stripped, so neither the fold nor the frame stripping depends on the payload's syntax. Ctrl+R toggles reasoning, Ctrl+L redraws, and Ctrl+D exits while idle.

Tool and injected-context cards collapse long bodies into a configurable head/tail preview; Ctrl+O cycles tool cards through collapsed preview, full output, and hidden — the hidden phase drops tool cards from the transcript entirely while context cards stay at their preview, since injected instructions are not tool traffic. An injected-context card renders its message as prose with the producer's outer reminder frame stripped, so neither the fold nor the frame stripping depends on the payload's syntax. Ctrl+R toggles reasoning, Ctrl+L redraws, and Ctrl+D exits while idle.
 
 `/model` opens the advisory `ctx.llm` catalog as a keyboard selector: a filter box above the list narrows rows by a case-insensitive substring over each row's `provider/model` label, model name, and description, keeping the highlighted row selected when it survives the filter; Up/Down moves, Shift+Tab cycles the focused model's adapter-advertised reasoning efforts in display order, Enter selects the model and effort, and Escape clears a non-empty filter before a second Escape closes it. When an adapter does not advertise a default effort, the cycle also includes `Default`, which clears an explicit selection and preserves the provider default; models without selectable effort metadata ignore Shift+Tab. The selector renders the exact advertised effort list—including `off` when present—and does not synthesize, clamp, or transfer an effort between models. `/model ` still selects an unambiguous model id directly, while `/model /` selects an exact target and uses its adapter default when one exists. The configured target or latest logged request header initializes the selector, and an unlisted current model remains visible because catalogs are advisory. Selection is local to this TUI session. Prompt assembly snapshots the target for one step, replaces `{{provider}}` and `{{model}}`, and applies the same provider/model/reasoning-effort target through `agent/request`; a switch during assembly therefore starts with a later step. The request header durably records targets that reach the model, while an unused selection remains process-local.

 挂载可选的 `ctx.sessionReferences` 后，同一个 `@` 菜单还会提供仅含元数据的会话候选项，插入 `@[label](dsh-session:)`，并在分派前准备所选快照。会话引用保持结构化，因为模型没有类似文件系统的工具可在稍后检索会话快照。准备期间会禁止重复提交，并在失败时恢复编辑器输入。TUI 会在异步准备后根据状态选择 `agent.steer()` 或 `agent.followup()`，因此空闲 followup 仍会分派 `agent/prompt-submit`，而轮次中的 steering 会在检查点加入且不触发该 hook。
 
-Agent 运行时，普通编辑器提交会调用 `agent.steer()`；其他时候调用 `agent.followup()`。提交行以斜杠开头时会改为进入 `ctx.commands`：已知命令直接执行，未知命令产生警告，两条路径都不会自动到达模型。命令生产方可以显式调度 agent 工作；[`dsh-plan-mode`](../../plan/plan-mode/README.md#model-and-human-surfaces) 使用该契约实现 `/plan [message]`。TUI 将 `/help`、`/model`、`/clear`、`/palette`、`/reload`、`/resume`、`/status` 和 `/exit` 注册为 agent 作用域定义；其他所有有效命令都会动态加入自动补全与 `/help`，`/skill:` 补全也相同。编辑器上方的状态行会报告 TUI 从会话事件派生的轮次阶段，包括等待首个 token、思考、响应或执行工具；它显示该阶段已经过时间和运行中的步骤总数，每秒刷新，并以 `Enter sends steering, Esc cancels` 提示结尾。Steering 消息等待到达模型期间，会在提示前插入 `N queued ·` 徽标，每条消息排空后随即清除。Ctrl+C 或 Escape 会取消运行中的轮次。工具卡片与注入上下文卡片都把长主体折叠为可配置的头尾预览；Ctrl+O 让工具卡片在折叠预览、完整输出、隐藏三种状态间循环——隐藏阶段把工具卡片从 transcript 中完全去掉，而上下文卡片保持预览，因为注入的指令不属于工具流量。注入上下文卡片把消息渲染为文本，并去掉生产方的外层提醒外框，因此折叠与去外框都不依赖载荷的语法。Ctrl+R 切换 reasoning，Ctrl+L 重绘，Ctrl+D 在空闲时退出。

 `/model` 将建议性的 `ctx.llm` catalog 打开为键盘选择器：列表上方设有一个过滤框，按对每行 `provider/model` 标签、模型名称和描述的大小写不敏感子串匹配来缩小行集，并在高亮行仍通过过滤时保持其选中状态；Up/Down 移动，Shift+Tab 按显示顺序循环切换适配器为焦点模型公布的推理强度，Enter 选择模型和推理强度，Escape 会先清除非空过滤内容，再次按下才关闭选择器。适配器未公布默认推理强度时，循环还会包含 `Default`，该项会清除显式选择并保留提供方默认行为；没有可选推理强度元数据的模型会忽略 Shift+Tab。选择器会原样呈现公布的推理强度列表（包括存在时的 `off`），不会合成、自动调整或在模型之间转移推理强度。`/model ` 仍可直接选择无歧义的模型 id，`/model /` 则选择精确目标，并在存在时使用其适配器默认值。已配置目标或最新记录的请求 header 会初始化选择器；由于 catalog 仅提供建议，未列出的当前模型仍会显示。选择仅对本 TUI 会话有效。提示词组装会为一个步骤建立目标快照，替换 `{{provider}}` 和 `{{model}}`，并通过 `agent/request` 应用同一个提供方／模型／推理强度目标；因此组装期间的切换会从后续步骤开始生效。请求 header 会持久记录真正到达模型的目标，未使用的选择则只存在于进程本地。

 `@deepseek-ai/dsh-command-compact` registers one argument-free human command through `ctx.commands`. It calls the third abstract `CompactService` operation, `compactNow(agent, signal)`, and maps the closed `ManualCompactionError` taxonomy (`busy | changed | summary | commit | persistence`) to direct UI results. `command/run` and `command/done` preserve the command lifecycle without entering model history or consuming a model-loop turn.
 
+The command plugin tracks each real handler promise independently of the command executor's abort-aware wait. Its composite lifecycle effect unregisters `/compact` before asynchronously draining handlers that already started, so root teardown reaches quiescence only after backend close and flush work settles.
+
 The seam's `ManualCompactAgentContext` adds only `reserveTurnAdmission()` to the session and routing facts compaction already needs. Retention, balancing, summarization, marker ordering, replacement, and durability remain backend responsibilities.

 The compaction invariant uses the same transition logic during seed replay: `session/end-seed` clears an open historical trace. The boundary need not publish live from the constructor for this case; replay is the load-bearing path.
 
+The client request projection closes an unmatched compaction request as interrupted at the `session/end-seed` time and clears its active index. A later `compact/start` therefore creates an independent request instead of leaving or overwriting a permanently running orphan.
+
 Once a transaction has appended its start, every later failure makes one closing attempt. A failed close leaves the unmatched start deliberately visible and blocking, and no flush is attempted. A closed manual attempt is flushed even when it reports an expected failure. Cancellation retains exact-reason precedence after required close and flush cleanup.

-The section states only facts shared by every enforcement dialect for each registered family. `read-only` says those operations cannot modify files. `workspace-write` states the canonical session workspace with non-exclusive wording and summarizes, without enumerating, that some platform temporary areas may also be writable. `danger-full-access` says the DSH file sandbox does not restrict those operations. Backend-selected temporary paths, `/dev/null`, runner readiness, and other policy domains are absent because `resolve()` cannot establish them at request assembly.
+The contribution states only facts shared by every enforcement dialect for each registered family. `read-only` says those operations cannot modify files in the standing mode. Tool owners separately register a family only when their real schema and execution path offer an approved wider retry; the read-only text adds anti-refusal guidance only for the intersection of enforced and escalatable families. `workspace-write` states the canonical session workspace with non-exclusive wording and summarizes, without enumerating, that some platform temporary areas may also be writable. `danger-full-access` says the DSH file sandbox does not restrict those operations. Backend-selected temporary paths, `/dev/null`, runner readiness, and other policy domains are absent because `resolve()` cannot establish them at request assembly.
 
-The provider runs during normal request assembly, after a `/permission` switch has committed its existing `sandbox/mode` event and before `request/header` is logged. The rendered system text is therefore the durable reconstruction of the exact model-visible fact. Repeated assemblies over unchanged session state produce identical bytes; resume and replay fold the same durable mode event and immutable `SessionHeader.cwd` without catch-up state.
+The existing `dsh-system-prompt` assembly now has ordered dynamic contexts alongside stable system sections and tool schemas. After assembling one step, agent-loop renders all active contexts as one full snapshot with an explicit supersession statement. It appends a sourced `user/message` only when no retained snapshot exists, the bytes changed, compaction removed the retained message, or the final contribution disappeared and needs one clearing snapshot. The snapshot is appended after existing history and before `step/start`, so a changed policy preserves the preceding system-and-conversation cache prefix. The session event itself reconstructs the exact model input; `request/header` remains byte-identical when only policy context changes.
 
-Ownership stays narrow. Approval policy remains the separate `approval:policy` section, plan mode remains `plan:policy`, and tool plugins continue to own schemas plus attempt, denial, and escalation guidance. The prompt states standing policy; filesystem, one-shot bash, and terminal backends remain the enforcement boundaries.
+Ownership stays narrow. Approval policy contributes its complete current `ask` or `never` fact to the same full snapshot; migrating sandbox alone would not preserve cache because `/permission` changes both owners. Plan mode remains `plan:policy`, and tool plugins continue to own schemas plus attempt, denial, and escalation guidance. Context states standing policy; filesystem, one-shot bash, and terminal backends remain the enforcement boundaries.
+
+The cache decision follows current source rather than analogy alone. Codex models permissions as a developer-role `WorldState` section with a persisted fingerprint, emits it only when state changes or retained history lost the fragment, and records the snapshot transition. Hermes keeps its system prompt fixed for a session and explicitly prepends changing skill, model, and voice notices to the next user message to avoid invalidating prompt cache. Pi has no comparable built-in sandbox state, and Claude Code's current native implementation is not publicly inspectable; Anthropic's public cache guidance nevertheless places changing per-request context after the stable cached prefix.
+
+The earlier real-provider Web fixture quantified the defect in the system-section version. The first `danger-full-access` and `workspace-write` requests each reported only 256 cache-read tokens against 14,691 and 14,782 uncached input tokens. Later steps under an unchanged policy reported approximately 14.7k–15.5k cache-read tokens. Moving only the sandbox sentence would not fix those misses because the same preset switch also rewrote the approval-policy system section.
 
 ## Wording evidence
 
@@ -26,24 +30,32 @@ The wording experiment pre-registered preemptive refusal as its primary endpoint
 
 The positive control therefore failed the pre-registered sensitivity gate. Candidate A and B were not run, and this experiment does not select or validate the current wording. It instead establishes that the earlier five-of-twelve result is not reproducible under this task and current tool guidance, and that a stronger positive control or different task distribution is required before making model-behavior rate claims. Deterministic tests below establish truthful request construction and replay only.
 
+The cache-safe delivery rework then supplied a separate, non-statistical acceptance comparison over the neutral Web task `Create the relative path policy-neutral.txt ...`; it does not replace the pre-registered twelve-session experiment. Candidate A's categorical read-only statement produced a text refusal with zero tool calls. Candidate B added one composition-conditioned sentence only for enforced families whose tools expose escalation. A fresh real-provider run then issued an ordinary `write`, observed the read-only denial, retried the same operation in the same turn with `sandbox_permissions: "workspace-write"`, received approval, read the file back, and verified the exact contents. It made no speculative escalation. Across the permission switches and four mutation steps, cache reads were 14,848–15,872 tokens while uncached input was 59–251 tokens per request, directly demonstrating the stable-prefix benefit.
+
 ## Alternatives considered
 
 **Narrate only mode changes.** Rejected because it leaves a fresh session uninformed and makes the first denied operation the policy-discovery mechanism. It also requires a baseline definition that is unnecessary when current state can be rendered directly.
 
 **Scan denial history or remember the last narrated mode.** Rejected because denial events describe attempted operations, not authoritative current state, while process-local bookkeeping does not survive resume. The owner can fold the durable policy directly on every request.
 
-**A generic runtime-facts registry.** Rejected because the existing system-prompt registry already evaluates owner-provided sections with the live agent at request time. One policy owner has no cross-domain invariant that justifies another package or registry.
+**Put current policy in a dynamic system section.** Rejected after real provider evidence showed that a first-time permission switch reduced cache reads to 256 tokens while roughly 14.7k input tokens missed. DeepSeek matches complete prefixes; changing the first wire message prevents reuse of the longer system-plus-history prefix.
 
-**Repeat tool schemas or approval and plan guidance in the section.** Rejected because those surfaces already have owners and independent lifecycles. Duplicating them would create contradictory request prefixes and broaden invalidation.
+**Call `agent.inject()` independently from each policy owner.** Rejected because sibling listener order would define model order, separate messages could expose mismatched intermediate snapshots, and every owner would need its own compaction-retention scan. The existing assembly owner can order contributions and materialize one atomic full snapshot.
+
+**A generic runtime-facts package.** Rejected because the existing system-prompt assembly already owns sections, schemas, variables, scope, and the authoritative per-step waterfall. Extending that owner with ordered contexts adds no package or second registry service.
+
+**Repeat tool schemas or plan guidance in the context.** Rejected because those surfaces already have owners and independent lifecycles. Approval current state joins the snapshot only because the same `/permission` switch changes it and leaving its system section would retain the cache defect.
+
+**Keep Candidate A after the cache-safe move.** Rejected by the neutral real-provider task: the model returned a pure text refusal and made no tool call despite the existing bash attempt guidance. Candidate B states no escalation mechanics itself; it tells only families whose tools actually advertise a wider retry not to infer impossibility from the standing label, then delegates denial and escalation behavior back to those tool owners.
 
 **Keep sandbox mode absent because a standing mode label once caused preemptive refusal.** Rejected because a fresh Web request otherwise exposes mutation tools while withholding their standing policy, producing false capability claims before the first operation. The earlier live measurement remains a required counter-test: five of twelve turns ended without a tool call under `Bash commands run under the "read-only" file sandbox.` The committed tool-owned attempt guidance postdates that measurement, so the replacement is selected through a new positive-control experiment under the current tool contract rather than assuming the old and current conditions match.
 
-**A separate model-context package.** Rejected because Cordis services can observe current runtime contributions directly, while approval and plan policy sections already live with their owners. A new package would add a shallow composition seam and documentation/gate surface for one internal adapter.
+**A separate model-context package.** Rejected because Cordis services can observe current runtime contributions directly and the existing assembly service can order them. A new package would add a shallow composition seam and documentation/gate surface around the same request boundary.
 
 **Enumerate writable temporary roots.** Rejected because the backend is selected later at `confine()`: bwrap, Landlock, Seatbelt, and the in-process filesystem fence do not grant one common temporary-path set. Host-specific paths in a standing request would be both unstable and overclaimed.
 
 ## Consequences
 
-A model can answer what registered file operations the standing mode governs before probing a tool, and the next request after `/permission` reflects the committed mode. This adds a small dynamic system section and intentionally invalidates the request prefix when policy or enforcing-family composition changes; unchanged state remains cache-stable. The statement is guidance, not an enforcement guard: runtime safety still comes from the registered filesystem, one-shot bash, and terminal backends consuming the same resolved policy.
+A model can answer what registered file operations the standing mode governs before probing a tool, and the next request after `/permission` reflects the committed mode. The stable system prompt no longer changes for sandbox or approval state; a changed full context snapshot is append-only after retained history, and unchanged state adds no message. Older snapshots remain in history but are explicitly superseded by the latest full snapshot.

-Focused tests pin all modes, family combinations, contribution disposal, canonical roots, switch timing, and byte stability across different `TMPDIR` values. Keyless assembled snapshots pin the request header through real Loader compositions, including all three families. Keyless replay owns the neutral denial-to-escalation trajectory; it is a structural regression proof, not wording-selection evidence.

+现有 `dsh-system-prompt` 组装在稳定系统段与工具 schema 之外，还包含有序的动态上下文。组装一个步骤后，agent loop（智能体循环）会将所有活动上下文渲染成一份带显式取代声明的完整快照。仅当不存在保留快照、字节发生变化、压缩（compaction）移除了保留消息，或最后一项贡献消失而需要一份清除快照时，它才会追加一条带来源的 `user/message`。快照追加在现有历史之后、`step/start` 之前，因此策略变化时仍会保留此前的系统与对话缓存前缀。会话事件本身可以重建确切的模型输入；只有策略上下文变化时，`request/header` 仍逐字节相同。

 **扫描拒绝历史或记住上次叙述的模式。** 不予采用，因为拒绝事件描述的是尝试过的操作，而不是权威的当前状态；进程本地的簿记也无法跨恢复保留。归属方可以在每次请求时直接折叠持久策略。

+**由每个策略归属方独立调用 `agent.inject()`。** 不予采用，因为同级监听器的顺序会决定模型所见顺序，分开的消息可能暴露不匹配的中间快照，并且每个归属方都需要各自扫描压缩后的保留状态。现有组装归属方可以对贡献排序，并具体化一份原子化的完整快照。
+
+**通用运行时事实包。** 不予采用，因为现有系统提示词组装已经拥有段、schema、变量、作用域和权威的逐步骤 waterfall（瀑布式事件）。为该归属方增加有序上下文，无需新增包或第二个注册表服务。
+
+**在上下文中重复工具 schema 或计划引导。** 不予采用，因为这些接口已有各自归属方和独立生命周期。批准的当前状态加入快照，仅仅是因为同一个 `/permission` 切换会改变它，而把它留在系统段会保留缓存缺陷。
+
+**缓存安全迁移后仍保留 Candidate A。** 不予采用，因为中性的真实提供方任务中，尽管已有 bash 尝试引导，模型仍以纯文本拒绝，且没有调用工具。Candidate B 本身不说明任何升权机制；它只针对那些工具确实公开更宽松模式重试的家族，说明不能从常驻标签推断操作不可能完成，然后把拒绝与升权行为交还给这些工具归属方。
 
 **继续省略沙箱模式，因为常驻模式标签曾引发预防性拒绝。** 不予采用，因为新的 Web 请求否则会暴露变更工具，却隐去这些工具的常驻策略，导致模型在首次操作前错误声称自身能力。先前的线上测量仍是必须执行的反证测试：使用 `Bash commands run under the "read-only" file sandbox.` 时，十二个轮次中有五个没有调用工具。已提交的工具归属方尝试引导晚于该测量，因此应通过当前工具契约下的新阳性对照实验选择替代文案，而不能假设旧条件与当前条件相同。

 ## 后果
 
-模型可以在试探工具前回答常驻模式管辖哪些已注册文件操作，且 `/permission` 后的下一个请求会反映已提交的模式。这会增加一个小型动态系统段落，并在策略或强制执行家族组合变化时有意使请求前缀缓存失效；状态不变时仍保持缓存稳定。该声明是引导，而不是强制执行护栏：运行时安全仍来自已注册的文件系统、一次性 bash 与终端后端消费同一项解析完成的策略。

 Escalating bash calls resolve `ctx.approval` before execution. `allowed-once` applies the requested mode only to that call; rejection, cancellation, unavailability, or missing approval context executes nothing and returns a distinct error. On a real denial, the model may retry the same command once in the same turn with the narrowest sufficient mode and justification; the approval prompt itself is the consent step. Escalation is never speculative, and a disabled or rejected approval is final. The [sandbox Agent Note](../../../.agents/notes/implemented/feature/2026-07-06-sandbox.md) owns the rationale.
 
+When the executor confines and the schema exposes escalation, this plugin registers the `bash` family as escalatable with `ctx.sandboxPolicy`. The policy owner can therefore add anti-refusal context only when the actual bash tool offers the denial-and-approved-retry path; the contribution disposes with the plugin.

 ## Per-session mode switching
 
-For sandboxing executors, each call resolves mode as one-shot escalation, then session override, then executor default. Non-sandboxing and agent-less calls carry no session override. Neither the prompt nor a switch notice announces the standing mode; denial results report the effective mode when the boundary matters. See the [`dsh-bash` fold](../bash/README.md) and [sandbox switching contract](../../../.agents/notes/implemented/feature/2026-07-06-sandbox.md).

 ### Public API
 
 - `ctx.systemPrompt.section(section: PromptSection): () => void` Contribute a section. The layer is the calling context's scope: `agent.ctx` contributes to that agent alone, shadowing a same-named global section there. Duplicate names within one layer and non-finite orders throw. Disposed with the calling fiber.
+- `ctx.systemPrompt.context(context: PromptContext): () => void` Contribute cache-safe dynamic model context. Contexts are ordered independently from system sections; scoped contributions shadow same-named globals. The agent loop materializes the complete current set as one sourced user-role snapshot after retained history, only when changed or missing. Duplicate names within one layer and non-finite orders throw. Disposed with the calling fiber.
 - `ctx.systemPrompt.tools(provider: (context: AssembleContext) => ToolProviderResult): () => void` Contribute tool schemas, evaluated at each assembly with that assembly's context. `ToolProviderResult` = `{ schemas, knownNames? }`: `schemas` is the post-restriction visible set; `knownNames` is the pre-restriction universe used by `toolOrder`. A provider must not return a schema named `TOOL_ORDER_REST`. Scoped providers are consulted only for their scope's assemblies. Disposed with the calling fiber.
 - `ctx.systemPrompt.variable(name: string, provider: (context) => string | undefined): () => void` Contribute a prompt variable, referenced from section text as `{{name}}`. Scoped variables shadow a same-named global for that agent. Duplicate-in-layer or unreferenceable names throw; `undefined` means "no value for this assembly". Disposed with the calling fiber.
 - `ctx.systemPrompt.assemble(context?: AssembleContext): Promise` Assemble the prompt for one caller: the global layer merged with `context.scope`'s layer, with tool schemas detached before the transform seam. Runs through the scope-filtered `system-prompt/assemble` waterfall and returns its authoritative result. An optional `context.signal` explicitly controls this assembly request; providers and listeners may cooperate with it but must not retain it for another turn. Rejects when a configured `toolOrder` names a tool outside the providers' `knownNames` universe, or when a provider returns the reserved rest-entry name.

 - `AssembleContext` — what one `assemble()` call is FOR. Merge-extensible; declares `scope?: ScopeKey` (the layer selector) and `signal?: AbortSignal` (the explicit request control capability) here, while `dsh-agent` declares `agent?: Agent` (the typed DX field — never set without `scope`; use `assembleContextFor(agent, signal)`). Providers must tolerate absent fields because a bare `assemble()` carries an empty, scope-less, signal-less context. `signal` is a request value, not part of the ambient Agent execution frame.
 - `PromptSection` — `{ name, order, text }`. Sections are concatenated in ascending `order`. Order bands: `-100` is the harness identity, `0` the deployment persona, tool guidance uses `100–199`.
-- `PromptAssembly` — `{ sections: AssembledSection[], tools: ToolSchema[], variables: Record }`. Section texts arrive resolved but not yet interpolated; `variables` holds every registered variable resolved against the context. Tool schemas are part of the assembly by design: "what the model is told it can do" is one coherent thing, even though adapters transmit schemas as a separate wire field.
+- `PromptContext` — `{ name, order, text }`. Contexts carry changing current facts that must not rewrite the cached system/history prefix; they use the same per-assembly provider and strict-variable contracts as sections.

Tool schemas are part of the assembly by design: "what the model is told it can do" is one coherent thing, even though adapters transmit schemas as a separate wire field.
 - `renderPrompt(assembly)` — interpolates `{{variable}}` references in each section, drops empty sections, joins with blank lines. STRICT: an unknown reference (`Object.hasOwn` lookup — prototype names like `{{constructor}}` are unknown), a registered-but-valueless reference, a malformed complete `{{…}}` group, or a `{{` that opens no complete group while a `}}` still follows (`{{{model}}}`) throws — fail loud beats shipping a malformed prompt. A lone `{{` with no `}}` anywhere after it passes through verbatim; substituted values are never re-scanned.
+- `renderContextSnapshot(assembly)` — applies the same strict interpolation to contexts, drops empty entries, and emits one full snapshot with an explicit supersession statement. An empty active set returns `''`; the loop emits one clearing snapshot when previously visible context disappears.
 
 Merge-extensible: plugins can declare extra fields on `PromptAssembly` and `AssembleContext` via declaration merging.
 
 ### Extension points
 
 - Section providers: tool packages own their cross-call guidance (`tool:bash`, `tool:read`, …); this plugin owns `harness:identity` and `deployment:persona`.
+- Context providers: policy and other changing-state owners contribute complete current facts without mutating the stable system prompt.
 - Variable providers: the agent loop registers `model` and `cwd`; any plugin can register the facts it owns (a future `date`, git state, …).
 - Tool schema providers: `ToolRegistry` registers itself as a tool provider automatically.
 - The [`system-prompt/assemble` waterfall](#live-events): cooperatively mutate or replace the assembly per caller.

 Prefix-stable while identity, persona, variables, section text, and order render identically. Any change may invalidate reuse from the first changed system-prompt token.
 
+### Dynamic runtime context
+
+#### What the model sees
+
+Active contexts are joined in deterministic order after strict interpolation and logged as one sourced user-role message immediately before the request that first needs that snapshot. The message begins `Current runtime context. This snapshot supersedes earlier runtime-context snapshots.` A changed snapshot is appended after retained history; an unchanged retained snapshot adds nothing. If compaction removes it, the current full snapshot is emitted again. Removing the last context emits one explicit clearing snapshot.
+
+#### Token effect
+
+One concise message on the first request, on an effective context change, after compaction removed the retained snapshot, or when the active set becomes empty. Unchanged steps add no duplicate tokens.
+
+#### KV Cache effect
+
+Append-only after retained history. A context change preserves the previously cached system and conversation prefix instead of rewriting the first wire message.

 The tool passes `exec` (the tool-execution context) as the opaque `actor` on every dispatch. The default thunks return `undefined` (the unconstrained bare provider). When `@deepseek-ai/dsh-fs-policy` is loaded it occupies the single decision slot — returning `createIfAbsent`/`replaceIfVersion`/`{ version }` or throwing `FS_NOT_OBSERVED` — and records on `fs/observed`. Backend errors (`FsError`) and a thrown `FS_NOT_OBSERVED` flow through `ToolRegistry.execute()` and become `isError` tool results with their `{ name, code }` attached.

 ## `fs/observed` is fire-and-forget
 
 `fs/observed` fires AFTER the read/write/edit already succeeded, via a plain `ctx.emit`. A listener is contractually a synchronous, side-effect-only recorder (`@deepseek-ai/dsh-fs-policy`'s is a `WeakMap.set`); the tool does not guard the emit, so a listener that throws would surface as the tool's `isError` result — async or fallible observation does not belong on this event.

 `fs/observed` 在读取/写入/编辑已经成功之后，通过普通 `ctx.emit` 发出。监听器的契约是同步且只有副作用的记录器（`@deepseek-ai/dsh-fs-policy` 使用 `WeakMap.set`）；工具不保护这次发出，因此监听器抛出会作为工具的 `isError` 结果出现。异步或可能失败的观察不属于该事件。

 #### Token 影响
 
-每个请求增加一个简洁的系统段落。`workspace-write` 只携带规范化的会话工作区路径；平台特定的临时路径会以摘要表述，不会加入依赖主机的字节。
+首次请求和有效策略每次变化时增加一条简洁的持久上下文消息；未变化的请求不增加内容。`workspace-write` 只携带规范化的会话工作区路径；平台特定的临时路径会以摘要表述，不会加入依赖主机的字节。
 
 #### KV Cache 影响
 
-只要会话模式与不可变工作区根目录不变，请求前缀就在字节层面保持稳定。模式切换会在下一次请求中改变该段落；生成的 `request/header` 会记录新的前缀。
+模式切换时，稳定的系统提示词仍逐字节相同。变化后的完整上下文快照会追加到保留的历史之后，从而保留此前已缓存的前缀；后续未变化的请求会复用该保留快照。
 
 ## 已知限制与暂缓事项
 
 - **每个会话只有一个主要工作区根目录**：策略解析 `SessionHeader.cwd`；额外可写根目录不属于 `SandboxExecutionPolicy`。
 - **仅限文件操作模式**：`SandboxMode` 管控文件操作；网络和进程策略不在其词汇中，因此这里没有限制它们的旋钮。
-- **有意概述临时区域**：强制执行后端会授予不同的平台临时区域，这些区域在策略解析后才会选定，因此无法在常驻段落中如实枚举。

+`ApprovalPolicy` is `'ask'` or `'never'`. The effective value is the last `approval/policy` event, falling back to config; `setApprovalPolicy()` is the write path. `'never'` rejects before interactive dispatch. Both policies contribute their complete current meaning to the cache-safe runtime-context snapshot.
 
 The tools pipeline routes `ask` decisions through this seam and fails closed when it is absent; the sandboxed bash tool also uses it for escalated retries. The ACP automation bridge answers calls for its own agents through the client's machine policy. Audit events remain log-only, so the model sees only the asking consumer's result. See the [approval-seam Agent Note](../../../.agents/notes/implemented/feature/2026-07-06-approval-seam.md) and [sandbox Agent Note](../../../.agents/notes/implemented/feature/2026-07-06-sandbox.md).
 
 ## Model Experience
 
-### System prompt and policy notice
+### Current approval policy context
 
 #### What the model sees
 
-Under `ask`, every agent request carries the ask-policy prompt section below. Under `never`, it carries the never-policy prompt section below. A policy switch injects exactly `The approval policy changed from "" to "" (changed by the user).` or `The approval policy changed from "" to "" (changed by the operator/config).` before the next step.
+The first request and each effective policy change append a full runtime-context snapshot after retained history. Under `ask`, the approval contribution states that configured answerers may be consulted and absence fails closed. Under `never`, it states the deterministic rejection and non-escalation consequence. Unchanged requests retain the earlier snapshot without adding another message.
 
-##### Ask-policy prompt section
+##### Ask-policy contribution
 
 ```markdown
-
+Approval policy: ask. Operations that require approval may ask through the configured answerers; without an available answerer, the request fails closed.
 ```
 
-##### Never-policy prompt section
+##### Never-policy contribution
 
 ```markdown
 Approval prompts are disabled in this session: actions that require approval are rejected automatically — do not request sandbox escalation (do not set `sandbox_permissions`).
-
 ```
 
 #### Token effect
 
-Small fixed per-request cost, larger under `never`; a change notice is conditional and retained in history.
+One concise context message on the first request and on an effective change; unchanged requests add no duplicate policy tokens.
 
 #### KV Cache effect
 
-Prefix-stable while the approval policy is unchanged. An `ask`/`never` switch changes the system-prompt section and invalidates reuse from its first changed token; the accompanying notice is append-only.
+Append-only after retained history. An `ask`/`never` switch preserves the stable system and conversation prefix instead of rewriting the first wire message.

 应答者是 `approval/request` waterfall（瀑布式事件）监听器。要回答其负责的 agent 请求，请返回一个结果；否则调用 `next()` 委托。限定到 agent 的监听器只接收该 agent 的请求；每项部署应当组合一个最终应答者，因为同级监听器的顺序不是策略优先级机制。ACP（Agent Client Protocol）自动化桥接层为其负责的会话提供一次性机器决定。
 
-`ApprovalPolicy` 为 `'ask'` 或 `'never'`。实际值取最后一条 `approval/policy` 事件，并回退到配置；`setApprovalPolicy()` 是写入路径。`'never'` 会在交互式分发之前拒绝请求，也是提示词中唯一声明的策略。切换最多产生一条合并通知：如果覆盖发生在最后一个 `request/header` 之后，则归因于用户；否则归因于操作方／配置。
+`ApprovalPolicy` 为 `'ask'` 或 `'never'`。实际值取最后一条 `approval/policy` 事件，并回退到配置；`setApprovalPolicy()` 是写入路径。`'never'` 会在交互式分发之前拒绝请求。两种策略都会将各自完整的当前含义贡献给缓存安全的运行时上下文快照。
 
 工具流水线通过此 seam 路由 `ask` 决定，并在该 seam 缺失时以拒绝方式关闭；沙箱 bash 工具也会将它用于升权重试。ACP 自动化桥接层根据客户端的机器策略，回答其自有 agent 的调用。审计事件仍只写入日志，因此模型只会看到发起请求的消费方所返回的结果。详见[审批 seam Agent Note（agent 决策记录）](../../../.agents/notes/implemented/feature/2026-07-06-approval-seam.md)和[沙箱 Agent Note](../../../.agents/notes/implemented/feature/2026-07-06-sandbox.md)。
 
 ## 模型体验
 
-### 系统提示词与策略通知
+### 当前审批策略上下文
 
 #### 模型看到的内容
 
-在 `ask` 下，每个 agent 请求都会携带下方的 ask 策略提示词段。在 `never` 下，请求会携带下方的 never 策略提示词段。策略切换会在下一步骤前精确注入 `The approval policy changed from "" to "" (changed by the user).` 或 `The approval policy changed from "" to "" (changed by the operator/config).`。
+首次请求和有效策略每次变化时，都会在保留的历史后追加一份完整运行时上下文快照。在 `ask` 下，批准贡献会说明可咨询已配置的应答者，缺少应答者时以拒绝方式关闭。在 `never` 下，它会说明确定性的拒绝与非升权后果。未变化的请求会保留先前快照，不增加另一条消息。
 
-##### Ask 策略提示词段
+##### Ask 策略贡献
 
 ```markdown
-
+Approval policy: ask. Operations that require approval may ask through the configured answerers; without an available answerer, the request fails closed.
 ```
 
-##### Never 策略提示词段
+##### Never 策略贡献
 
 ```markdown
 Approval prompts are disabled in this session: actions that require approval are rejected automatically — do not request sandbox escalation (do not set `sandbox_permissions`).
-
 ```
 
 #### Token 影响
 
-每个请求有少量固定成本，`never` 下的成本更高；变更通知按条件出现，并保留在历史中。
+首次请求和策略实际变化时增加一条简洁的上下文消息；未变化的请求不增加重复的策略 token。
 
 #### KV Cache 影响
 
-审批策略不变时，前缀保持稳定。`ask`／`never` 切换会改变系统提示词段，并从首个变化的 token 开始使复用失效；随附通知只会追加。
+在保留的历史之后仅追加。`ask`／`never` 切换会保留稳定的系统与对话前缀，而不会改写第一条 wire 消息。

 The wording experiment pre-registered preemptive refusal as its primary endpoint and required the old standing sentence to produce at least one refusal in twelve fresh sessions before any replacement could be judged. On 2026-07-30, commit `2bf41990401b194bd8637f07bbd90c67a9eeac75` ran `deepseek-v4-flash` through the shipped Web composition with the exact positive-control sentence `Bash commands run under the "read-only" file sandbox.` and the current tool-owned attempt guidance. The control produced zero preemptive refusals and zero speculative escalations; all twelve sessions made an ordinary bash call, observed a denial, escalated in the same turn, received approval, and landed the requested file. No sample was excluded.
 
-The positive control therefore failed the pre-registered sensitivity gate. Candidate A and B were not run, and this experiment does not select or validate the current wording. It instead establishes that the earlier five-of-twelve result is not reproducible under this task and current tool guidance, and that a stronger positive control or different task distribution is required before making model-behavior rate claims. Deterministic tests below establish truthful request construction and replay only.
+After the cache-safe delivery change, commit `10d4e0ff7b68d38fc4403403b644aac442b97a00` repeated the same twelve-session positive control through the new tail-context channel. It again produced zero preemptive refusals and zero speculative escalations; all twelve sessions made an ordinary first call, observed denial, escalated in the same turn, and received approval. Eight landed the exact requested file, and no sample was excluded.

+Both positive controls therefore failed the pre-registered sensitivity gate. The formal twelve-session Candidate A and B arms were not run, and these experiments do not select or validate the current wording. They establish that the earlier five-of-twelve result is not reproducible under this task and current tool guidance, and that a stronger positive control or different task distribution is required before making model-behavior rate claims. Deterministic tests below establish truthful request construction and replay only.
 
 The cache-safe delivery rework then supplied a separate, non-statistical acceptance comparison over the neutral Web task `Create the relative path policy-neutral.txt ...`; it does not replace the pre-registered twelve-session experiment. Candidate A's categorical read-only statement produced a text refusal with zero tool calls. Candidate B added one composition-conditioned sentence only for enforced families whose tools expose escalation. A fresh real-provider run then issued an ordinary `write`, observed the read-only denial, retried the same operation in the same turn with `sandbox_permissions: "workspace-write"`, received approval, read the file back, and verified the exact contents. It made no speculative escalation. Across the permission switches and four mutation steps, cache reads were 14,848–15,872 tokens while uncached input was 59–251 tokens per request, directly demonstrating the stable-prefix benefit.

 措辞实验预先登记「预防性拒绝」为主要终点，并要求旧常驻句子在十二个 fresh session 中至少产生一次拒绝，之后才能评判任何替代措辞。2026-07-30，commit `2bf41990401b194bd8637f07bbd90c67a9eeac75` 通过已交付的 Web 组合运行 `deepseek-v4-flash`，使用精确的阳性对照句子 `Bash commands run under the "read-only" file sandbox.` 与当前工具归属方的尝试引导。对照组产生零次预防性拒绝和零次推测性升级；十二个会话全部先发起普通 bash 调用、观察到拒绝、在同一轮次升级、获得批准，并让所请求文件实际落盘。没有样本被排除。
 
-因此，阳性对照未通过预先登记的灵敏度门槛。Candidate A 与 B 均未运行，本实验不选择也不验证当前措辞。它只说明先前十二次中五次的结果无法在本任务与当前工具引导下复现；在声明模型行为率之前，需要更强的阳性对照或不同的任务分布。下述确定性测试只证明请求构造与回放真实一致。
+缓存安全交付变更后，commit `10d4e0ff7b68d38fc4403403b644aac442b97a00` 通过新的尾部上下文通道重复了同一项十二会话阳性对照。结果再次为零次预防性拒绝和零次推测性升权；十二个会话的首次调用均为普通调用，随后观察到拒绝、在同一轮次升权并获得批准。其中八个会话让所请求文件按确切要求落盘，没有样本被排除。

+因此，两项阳性对照均未通过预先登记的灵敏度门槛。Candidate A 与 B 的正式十二会话实验组均未运行，这些实验不选择也不验证当前措辞。它们说明先前十二次中五次的结果无法在本任务与当前工具引导下复现；在声明模型行为率之前，需要更强的阳性对照或不同的任务分布。下述确定性测试只证明请求构造与回放真实一致。
 
 随后，缓存安全交付重做针对中性 Web 任务 `Create the relative path policy-neutral.txt ...` 提供了一次独立的非统计验收对比；它不取代预先登记的十二会话实验。Candidate A 的绝对化只读声明导致模型以纯文本拒绝，工具调用为零。Candidate B 只针对受强制执行、且其工具公开升权能力的家族增加一句按组合条件化的文案。随后一次全新的真实提供方运行先发出普通 `write`，观察到只读拒绝，再在同一轮次用 `sandbox_permissions: "workspace-write"` 重试同一操作，获得批准、读回文件并核验确切内容。它没有进行推测性升权。在权限切换和四个变更步骤中，每个请求的缓存读取为 14,848–15,872 个 token，未缓存输入为 59–251 个 token，直接证明了稳定前缀的收益。

The following skills are available in this session:\n\n\n- `15-05-premortem`: Use before starting risky work — rebases, large refactors, multi-file migrations, or deploys — to identify failure modes and mitigations in advance.\n- `acceptance-criteria`: 检查Acceptance Criteria格式和完整性，验证是否符合Given-When-Then结构、覆盖正常流程/边界条件/异常场景。适合在为User Story编写AC后、准备测试用例前使用，当需要验收AC质量时。帮助不熟悉BDD的PM/BA确保AC明确、可测试、覆盖完整，避免遗漏关键场景。\n- `agents-sdk`: Build AI agents on Cloudflare Workers using the Agents SDK. Load when creating stateful agents, durable workflows, real-time WebSocket apps, scheduled tasks, MCP servers, chat applications, voice agents, or browser automation. Covers Agent class, state management, callable RPC, Workflows, durable execution, queues, retries, observability, and React hooks. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.\n- `aico-pm-user-story-writing`: Transform requirements into well-structured User Stories using \"As a [user], I want [goal], So that [benefit]\" format with Given/When/Then acceptance criteria. Use this skill when: - User asks to \"write user story\", \"create story\", \"add story\" - User mentions \"user story\", \"backlog item\", \"story\" - Running /pm.plan and need to break PRD into implementable stories - Creating backlog items for development team - Need to formalize a requirement into standard story format - Converting feature req...\n- `algorithmic-art`: Creating algorithmic art using p5.js with seeded randomness and interactive parameter exploration. Use this when users request creating art using code, generative art, algorithmic art, flow fields, or particle systems. Create original algorithmic art rather than copying existing artists' work to avoid copyright violations.\n- `animation-vocabulary`: Reverse-lookup glossary that turns a vague description of a web animation or motion effect into its exact term (\"the bouncy thing when a popover opens\" → Pop in; \"the iOS rubber-band scroll\" → Rubber-banding). Use when the user asks \"what's it called when…\", or describes a motion effect without knowing its name and wants the right word to prompt an AI or designer with. For naming an effect, not designing or building one.\n- `app-comprehensive-test-generator`: Generate exhaustive user-flow and edge-case test scenarios from an app's codebase, produce scenario .md files, execute tests using connected or newly created MCPs, and produce an app.qa.report.md summarizing failures and suggested fixes.\n- `apple-design`: Apple's approach to interface design and fluid, physical motion, translated for the web. Use when building or reviewing gesture-driven UI, spring animations, drag/swipe/sheet interactions, momentum and interruptible transitions, translucent materials and depth, typography (optical sizing, tracking, leading), reduced-motion, or the design foundations (feedback, spatial consistency, restraint) behind Apple-style interfaces.\n- `brainstorming`: You MUST use this before any creative work - creating features, building components, adding functionality, or modifying behavior. Explores user intent, requirements and design before implementation.\n- `brand-guidelines`: Applies Anthropic's official brand colors and typography to any sort of artifact that may benefit from having Anthropic's look-and-feel. Use it when brand colors or style guidelines, visual formatting, or company design standards apply.\n- `canvas-design`: Create beautiful visual art in .png and .pdf documents using design philosophy. You should use this skill when the user asks to create a poster, piece of art, design, or other static piece. Create original visual designs, never copying existing artists' work to avoid copyright violations.\n- `claude-api`: Reference for the Claude API / Anthropic SDK — model ids, pricing, params, streaming, tool use, MCP, agents, caching, token counting, model migration. TRIGGER — read BEFORE opening the target file; don't skip because it \"looks like a one-liner\" — whenever: the prompt names Claude/Anthropic in any form (Claude, Anthropic, Fable, Opus, Sonnet, Haiku, `anthropic`, `@anthropic-ai`, `claude-*`, `us.anthropic.*`, `[1m]`); the user asks about an LLM (pricing/model choice/limits/caching) — never answ...\n- `cloudflare`: Comprehensive Cloudflare platform skill covering Workers, Pages, storage (KV, D1, R2), AI (Workers AI, Vectorize, Agents SDK), feature flags (Flagship), networking (Tunnel, Spectrum), security (WAF, DDoS), and infrastructure-as-code (Terraform, Pulumi). Use for any Cloudflare development task. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.\n- `cloudflare-email-service`: Send and receive transactional emails with Cloudflare Email Service (Email Sending + Email Routing).

Even for simple requests like \"add email to my Worker\" — this skill has critical conf...\n- `cloudflare-one`: Guides Cloudflare One Zero Trust and SASE work across Access, Gateway, WARP, Tunnel, Cloudflare WAN, DLP, CASB, device posture, and identity. Use when designing, configuring, troubleshooting, or reviewing Cloudflare One deployments. Retrieval-first: use current Cloudflare docs/API schemas instead of embedded product docs.\n- `cloudflare-one-migrations`: Plans migrations from Zscaler ZIA/ZPA, Palo Alto, legacy VPN, SWG, or SASE stacks to Cloudflare One. Use for migration assessments, policy mapping, rollout plans, and parity/gap analysis.\n- `code-review`: Review the changes since a fixed point (commit, branch, tag, or merge-base) along two axes — Standards (does the code follow this repo's documented coding standards?) and Spec (does the code match what the originating issue/PRD asked for?). Runs both reviews in parallel sub-agents and reports them side by side. Use when the user wants to review a branch, a PR, work-in-progress changes, or asks to \"review since X\".\n- `codebase-design`: Shared vocabulary for designing deep modules. Use when the user wants to design or improve a module's interface, find deepening opportunities, decide where a seam goes, make code more testable or AI-navigable, or when another skill needs the deep-module vocabulary.\n- `content-refiner`: Refine verbose educational content by eliminating redundancy, tightening prose, and strengthening lesson connections. Use when content is wordy, repetitive, or lacks narrative flow between sections.\n- `context-compression`: This skill should be used when long-running agent sessions need context compression, structured summarization, compaction, token-per-task optimization, or durable handoff summaries that preserve decisions, files, risks, and next actions.\n- `create-feishu-doc`: Create a Feishu document and grant edit permissions to the user. Use when asked to write content to Feishu or create a document in a wiki space.\n- `design-compass`: Use when doing any product or UI design work — brainstorming a feature, starting a visual/interaction direction, reviewing half-built UI, or final-checking before ship; also when unsure which design skill applies. 产品设计 / 界面设计 / 交互设计 / UI review / 脑暴 / 视觉方向 / 设计验收时使用。\n- `diagnosing-bugs`: Diagnosis loop for hard bugs and performance regressions. Use when the user says \"diagnose\"/\"debug this\", or reports something broken/throwing/failing/slow.\n- `doc-coauthoring`: Guide users through a structured workflow for co-authoring documentation. Use when user wants to write documentation, proposals, technical specs, decision docs, or similar structured content. This workflow helps users efficiently transfer context, refine content through iteration, and verify the doc works for readers. Trigger when user mentions writing docs, creating proposals, drafting specs, or similar documentation tasks.\n- `docx`: Comprehensive document creation, editing, and analysis with support for tracked changes, comments, formatting preservation, and text extraction. When Claude needs to work with professional documents (.docx files) for: (1) Creating new documents, (2) Modifying or editing content, (3) Working with tracked changes, (4) Adding comments, or any other document tasks\n- `domain-modeling`: Build and sharpen a project's domain model. Use when the user wants to pin down domain terminology or a ubiquitous language, record an architectural decision, or when another skill needs to maintain the domain model.\n- `durable-objects`: Create and review Cloudflare Durable Objects. Use when building stateful coordination (chat rooms, multiplayer games, booking systems), implementing RPC methods, SQLite storage, alarms, WebSockets, or reviewing DO code for best practices. Covers Workers integration, wrangler config, and testing with Vitest. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.\n- `ego-browser`: ego-browser (ego-lite) is a Chromium-based browser designed from the ground up to be friendly to both human users and AI Agents. AI Agents work in their own isolated space, reusing the user's login state without competing for the browser. Use this skill whenever the user needs to interact with a website opening pages, filling forms, clicking buttons, taking screenshots, extracting page data, testing web apps, logging into sites, automating browser operations, or any other browser automation t...\n- `emil-design-eng`: This skill encodes Emil Kowalski's philosophy on UI polish, component design, animation decisions, and the invisible details that make software feel great.\n- `feishu-workflow`: 飞书文档全流程管理 — 搜索、创建、编辑 wiki 文档，支持内容排版、表格、代码块、白板\n- `find-animation-opportunities`: Search a codebase or UI for places that don't animate but should, and reject everything that shouldn't. Read-only; it proposes motion with exact values, it does not implement it. Use when the user asks \"what could be animated here?\" or wants to \"make this feel more alive\". For fixing existing animations, use improve-animations or review-animations instead.\n- `frontend-design`: Guidance for distinctive, intentional visual design when building new UI or reshaping an existing one. Helps with aesthetic direction, typography, and making choices that don't read as templated defaults.\n- `gap-to-topic`: Turn a research area into a go/no-go decision dossier for ONE candidate thesis/proposal topic — a 3-gate verdict (is the gap open? is it a contribution? is it feasible?) with the evidence laid out so the researcher can verify it. Use when the user asks \"is this gap worth pursuing\", \"help me pick a thesis topic\", \"is this idea already taken\", \"find me a defensible research gap\", \"vet this research idea before I commit\", or \"should I do this\". NOT a literature review (use `literature-triage-mat...\n- `gc-minimal-zine-poster-v0-1`: Generate Minimal Zine Poster v0.1 poetic paper-poster prompts and the matching generated image. Use when the user gives a theme, sentence, object, mood, article idea, photo, or content brief and wants a quiet Japanese/Korean zine-like editorial poster with large negative space, aged paper texture, experimental typography, restrained color accents, and a generated bitmap image.\n- `grilling`: Grill the user relentlessly about a plan, decision, or idea. Use when the user wants to stress-test their thinking, or uses any 'grill' trigger phrases.\n- `grillme-workflow`: Use when implementing complex multi-step tasks that benefit from structured plan review, multi-model validation, and post-execution verification\n- `humanizer`: Remove signs of AI-generated writing from text. Use when editing or reviewing text to make it sound more natural and human-written. Based on Wikipedia's comprehensive \"Signs of AI writing\" guide.

Read-only on source code — it plans improvements, it does not apply them. Use when the user asks to \"improve the animations\", \"audit the motion\", \"make this app feel better\", or wants a roadmap of animation fixes rather than a review of a single diff.\n- `internal-comms`: A set of resources to help me write all kinds of internal communications, using the formats that my company likes to use.

The following skills are available in this session:\n\n\n- `15-05-premortem`: Use before starting risky work — rebases, large refactors, multi-file migrations, or deploys — to identify failure modes and mitigations in advance.\n- `acceptance-criteria`: 检查Acceptance Criteria格式和完整性，验证是否符合Given-When-Then结构、覆盖正常流程/边界条件/异常场景。适合在为User Story编写AC后、准备测试用例前使用，当需要验收AC质量时。帮助不熟悉BDD的PM/BA确保AC明确、可测试、覆盖完整，避免遗漏关键场景。\n- `agents-sdk`: Build AI agents on Cloudflare Workers using the Agents SDK. Load when creating stateful agents, durable workflows, real-time WebSocket apps, scheduled tasks, MCP servers, chat applications, voice agents, or browser automation. Covers Agent class, state management, callable RPC, Workflows, durable execution, queues, retries, observability, and React hooks. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.\n- `aico-pm-user-story-writing`: Transform requirements into well-structured User Stories using \"As a [user], I want [goal], So that [benefit]\" format with Given/When/Then acceptance criteria. Use this skill when: - User asks to \"write user story\", \"create story\", \"add story\" - User mentions \"user story\", \"backlog item\", \"story\" - Running /pm.plan and need to break PRD into implementable stories - Creating backlog items for development team - Need to formalize a requirement into standard story format - Converting feature req...\n- `algorithmic-art`: Creating algorithmic art using p5.js with seeded randomness and interactive parameter exploration. Use this when users request creating art using code, generative art, algorithmic art, flow fields, or particle systems. Create original algorithmic art rather than copying existing artists' work to avoid copyright violations.\n- `animation-vocabulary`: Reverse-lookup glossary that turns a vague description of a web animation or motion effect into its exact term (\"the bouncy thing when a popover opens\" → Pop in; \"the iOS rubber-band scroll\" → Rubber-banding). Use when the user asks \"what's it called when…\", or describes a motion effect without knowing its name and wants the right word to prompt an AI or designer with. For naming an effect, not designing or building one.\n- `app-comprehensive-test-generator`: Generate exhaustive user-flow and edge-case test scenarios from an app's codebase, produce scenario .md files, execute tests using connected or newly created MCPs, and produce an app.qa.report.md summarizing failures and suggested fixes.\n- `apple-design`: Apple's approach to interface design and fluid, physical motion, translated for the web. Use when building or reviewing gesture-driven UI, spring animations, drag/swipe/sheet interactions, momentum and interruptible transitions, translucent materials and depth, typography (optical sizing, tracking, leading), reduced-motion, or the design foundations (feedback, spatial consistency, restraint) behind Apple-style interfaces.\n- `brainstorming`: You MUST use this before any creative work - creating features, building components, adding functionality, or modifying behavior. Explores user intent, requirements and design before implementation.\n- `brand-guidelines`: Applies Anthropic's official brand colors and typography to any sort of artifact that may benefit from having Anthropic's look-and-feel. Use it when brand colors or style guidelines, visual formatting, or company design standards apply.\n- `canvas-design`: Create beautiful visual art in .png and .pdf documents using design philosophy. You should use this skill when the user asks to create a poster, piece of art, design, or other static piece. Create original visual designs, never copying existing artists' work to avoid copyright violations.\n- `claude-api`: Reference for the Claude API / Anthropic SDK — model ids, pricing, params, streaming, tool use, MCP, agents, caching, token counting, model migration. TRIGGER — read BEFORE opening the target file; don't skip because it \"looks like a one-liner\" — whenever: the prompt names Claude/Anthropic in any form (Claude, Anthropic, Fable, Opus, Sonnet, Haiku, `anthropic`, `@anthropic-ai`, `claude-*`, `us.anthropic.*`, `[1m]`); the user asks about an LLM (pricing/model choice/limits/caching) — never answ...\n- `cloudflare`: Comprehensive Cloudflare platform skill covering Workers, Pages, storage (KV, D1, R2), AI (Workers AI, Vectorize, Agents SDK), feature flags (Flagship), networking (Tunnel, Spectrum), security (WAF, DDoS), and infrastructure-as-code (Terraform, Pulumi). Use for any Cloudflare development task. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.\n- `cloudflare-email-service`: Send and receive transactional emails with Cloudflare Email Service (Email Sending + Email Routing). Use when building email sending (Workers binding or REST API), email routing, Agents SDK email handling, or integrating email into any app — Workers, Node.js, Python, Go, etc. Also use for email deliverability, SPF/DKIM/DMARC, wrangler email setup, MCP email tools, or when a coding agent needs to send emails. Even for simple requests like \"add email to my Worker\" — this skill has critical conf...\n- `cloudflare-one`: Guides Cloudflare One Zero Trust and SASE work across Access, Gateway, WARP, Tunnel, Cloudflare WAN, DLP, CASB, device posture, and identity. Use when designing, configuring, troubleshooting, or reviewing Cloudflare One deployments. Retrieval-first: use current Cloudflare docs/API schemas instead of embedded product docs.\n- `cloudflare-one-migrations`: Plans migrations from Zscaler ZIA/ZPA, Palo Alto, legacy VPN, SWG, or SASE stacks to Cloudflare One. Use for migration assessments, policy mapping, rollout plans, and parity/gap analysis.\n- `code-review`: Review the changes since a fixed point (commit, branch, tag, or merge-base) along two axes — Standards (does the code follow this repo's documented coding standards?) and Spec (does the code match what the originating issue/PRD asked for?). Runs both reviews in parallel sub-agents and reports them side by side. Use when the user wants to review a branch, a PR, work-in-progress changes, or asks to \"review since X\".\n- `codebase-design`: Shared vocabulary for designing deep modules. Use when the user wants to design or improve a module's interface, find deepening opportunities, decide where a seam goes, make code more testable or AI-navigable, or when another skill needs the deep-module vocabulary.\n- `content-refiner`: Refine verbose educational content by eliminating redundancy, tightening prose, and strengthening lesson connections. Use when content is wordy, repetitive, or lacks narrative flow between sections.\n- `context-compression`: This skill should be used when long-running agent sessions need context compression, structured summarization, compaction, token-per-task optimization, or durable handoff summaries that preserve decisions, files, risks, and next actions.\n- `create-feishu-doc`: Create a Feishu document and grant edit permissions to the user. Use when asked to write content to Feishu or create a document in a wiki space.\n- `design-compass`: Use when doing any product or UI design work — brainstorming a feature, starting a visual/interaction direction, reviewing half-built UI, or final-checking before ship; also when unsure which design skill applies. 产品设计 / 界面设计 / 交互设计 / UI review / 脑暴 / 视觉方向 / 设计验收时使用。\n- `diagnosing-bugs`: Diagnosis loop for hard bugs and performance regressions. Use when the user says \"diagnose\"/\"debug this\", or reports something broken/throwing/failing/slow.\n- `doc-coauthoring`: Guide users through a structured workflow for co-authoring documentation. Use when user wants to write documentation, proposals, technical specs, decision docs, or similar structured content. This workflow helps users efficiently transfer context, refine content through iteration, and verify the doc works for readers. Trigger when user mentions writing docs, creating proposals, drafting specs, or similar documentation tasks.\n- `docx`: Comprehensive document creation, editing, and analysis with support for tracked changes, comments, formatting preservation, and text extraction. When Claude needs to work with professional documents (.docx files) for: (1) Creating new documents, (2) Modifying or editing content, (3) Working with tracked changes, (4) Adding comments, or any other document tasks\n- `domain-modeling`: Build and sharpen a project's domain model. Use when the user wants to pin down domain terminology or a ubiquitous language, record an architectural decision, or when another skill needs to maintain the domain model.\n- `durable-objects`: Create and review Cloudflare Durable Objects. Use when building stateful coordination (chat rooms, multiplayer games, booking systems), implementing RPC methods, SQLite storage, alarms, WebSockets, or reviewing DO code for best practices. Covers Workers integration, wrangler config, and testing with Vitest. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.\n- `ego-browser`: ego-browser (ego-lite) is a Chromium-based browser designed from the ground up to be friendly to both human users and AI Agents. AI Agents work in their own isolated space, reusing the user's login state without competing for the browser. Use this skill whenever the user needs to interact with a website opening pages, filling forms, clicking buttons, taking screenshots, extracting page data, testing web apps, logging into sites, automating browser operations, or any other browser automation t...\n- `emil-design-eng`: This skill encodes Emil Kowalski's philosophy on UI polish, component design, animation decisions, and the invisible details that make software feel great.\n- `feishu-workflow`: 飞书文档全流程管理 — 搜索、创建、编辑 wiki 文档，支持内容排版、表格、代码块、白板\n- `find-animation-opportunities`: Search a codebase or UI for places that don't animate but should, and reject everything that shouldn't. Read-only; it proposes motion with exact values, it does not implement it. Use when the user asks \"what could be animated here?\" or wants to \"make this feel more alive\". For fixing existing animations, use improve-animations or review-animations instead.\n- `frontend-design`: Guidance for distinctive, intentional visual design when building new UI or reshaping an existing one. Helps with aesthetic direction, typography, and making choices that don't read as templated defaults.\n- `gap-to-topic`: Turn a research area into a go/no-go decision dossier for ONE candidate thesis/proposal topic — a 3-gate verdict (is the gap open? is it a contribution? is it feasible?) with the evidence laid out so the researcher can verify it. Use when the user asks \"is this gap worth pursuing\", \"help me pick a thesis topic\", \"is this idea already taken\", \"find me a defensible research gap\", \"vet this research idea before I commit\", or \"should I do this\". NOT a literature review (use `literature-triage-mat...\n- `gc-minimal-zine-poster-v0-1`: Generate Minimal Zine Poster v0.1 poetic paper-poster prompts and the matching generated image. Use when the user gives a theme, sentence, object, mood, article idea, photo, or content brief and wants a quiet Japanese/Korean zine-like editorial poster with large negative space, aged paper texture, experimental typography, restrained color accents, and a generated bitmap image.\n- `grilling`: Grill the user relentlessly about a plan, decision, or idea. Use when the user wants to stress-test their thinking, or uses any 'grill' trigger phrases.\n- `grillme-workflow`: Use when implementing complex multi-step tasks that benefit from structured plan review, multi-model validation, and post-execution verification\n- `humanizer`: Remove signs of AI-generated writing from text. Use when editing or reviewing text to make it sound more natural and human-written. Based on Wikipedia's comprehensive \"Signs of AI writing\" guide. Detects and fixes patterns including: inflated symbolism, promotional language, superficial -ing analyses, vague attributions, em dash overuse, rule of three, AI vocabulary words, passive voice, negative parallelisms, and filler phrases.\n- `improve-animations`: Survey a codebase's animation and motion code as a senior motion advisor, then produce a prioritized audit and self-contained implementation plans for other agents (or cheaper models) to execute.

 Track every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.
 
-Current DSH file policy: danger-full-access. The DSH file sandbox does not restrict the write and edit tools or one-shot bash commands.
-
 Use goal tools for one long-running completion objective in the current session. create_goal may infer goal intent from a direct human request in any language; do not create a goal for routine single-turn work. Call get_goal before update_goal and copy its exact goal_id and revision. After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.
 
-Approval prompts are disabled in this session: actions that require approval are rejected automatically — do not request sandbox escalation (do not set `sandbox_permissions`).

-
 Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.
 
 Use the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.

 Track every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.
 
-Current DSH file policy: danger-full-access. The DSH file sandbox does not restrict the write and edit tools or one-shot bash commands.
-
 Use goal tools for one long-running completion objective in the current session. create_goal may infer goal intent from a direct human request in any language; do not create a goal for routine single-turn work. Call get_goal before update_goal and copy its exact goal_id and revision. After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.
 
-Approval prompts are disabled in this session: actions that require approval are rejected automatically — do not request sandbox escalation (do not set `sandbox_permissions`).
-
-
 Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.
 
 Use the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.

-You are an AI agent powered by the DeepSeek Harness SDK.
-
-You are a coding assistant powered by the deepseek-v4-flash model. Your working directory is {{cwd}}. Your bash tool runs under a file sandbox — a `[sandbox: file access denied …]` result is policy, not a command bug.
-
-Verify your work by running the code or tests. Keep answers brief and factual.
-
-
-Use the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.
-
-Use the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.
-
-Use the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.
-
-Check the [exit code: N] marker on every bash result; investigate failures before moving on.
-
-Track every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.
-
-Current DSH file policy: workspace-write. The write and edit tools and one-shot bash commands may modify files under the session workspace: "{{cwd}}". Some platform temporary areas may also be writable.
-
-Use goal tools for one long-running completion objective in the current session. create_goal may infer goal intent from a direct human request in any language; do not create a goal for routine single-turn work. Call get_goal before update_goal and copy its exact goal_id and revision. After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.
-
-
-
-Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.
-
-Use the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.

 Track every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.
 
-Current DSH file policy: danger-full-access. The DSH file sandbox does not restrict the write and edit tools or one-shot bash commands.
-
 Use search/read for ordinary navigation. Use lsp when textual matches are ambiguous or before a change requires precise definitions, implementations, or references. Positions are one-based line and character (UTF-16) at the cursor; an off-symbol position may return no results. findReferences always includes the declaration.
 
 Use goal tools for one long-running completion objective in the current session. create_goal may infer goal intent from a direct human request in any language; do not create a goal for routine single-turn work. Call get_goal before update_goal and copy its exact goal_id and revision. After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.
 
-Approval prompts are disabled in this session: actions that require approval are rejected automatically — do not request sandbox escalation (do not set `sandbox_permissions`).
-
-
 Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.
 
 Use the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.

 Track every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.
 
-Current DSH file policy: danger-full-access. The DSH file sandbox does not restrict the write and edit tools, one-shot bash commands, or terminal sessions.
-
 Use goal tools for one long-running completion objective in the current session. create_goal may infer goal intent from a direct human request in any language; do not create a goal for routine single-turn work. Call get_goal before update_goal and copy its exact goal_id and revision. After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.
 
-Approval prompts are disabled in this session: actions that require approval are rejected automatically — do not request sandbox escalation (do not set `sandbox_permissions`).
-
-
 Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.
 
 Use the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.

 Track every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.
 
-Current DSH file policy: danger-full-access. The DSH file sandbox does not restrict the write and edit tools or one-shot bash commands.
-
 Use session_search to find relevant work from prior sessions, or session_event_search to search earlier events in one session. Search results are cursor-free and workspace-scoped. Follow a useful hit with session_trace, session_event_trace, or session_event_read when you need lineage, relationships, or exact data.
 
 Use goal tools for one long-running completion objective in the current session. create_goal may infer goal intent from a direct human request in any language; do not create a goal for routine single-turn work. Call get_goal before update_goal and copy its exact goal_id and revision. After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.
 
-Approval prompts are disabled in this session: actions that require approval are rejected automatically — do not request sandbox escalation (do not set `sandbox_permissions`).
-
-
 Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.
 
 Use the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.

 Track every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.
 
-Current DSH file policy: danger-full-access. The DSH file sandbox does not restrict the write and edit tools or one-shot bash commands.
-
 Use goal tools for one long-running completion objective in the current session. create_goal may infer goal intent from a direct human request in any language; do not create a goal for routine single-turn work. Call get_goal before update_goal and copy its exact goal_id and revision. After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.
 
-Approval prompts are disabled in this session: actions that require approval are rejected automatically — do not request sandbox escalation (do not set `sandbox_permissions`).

-
 Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.
 
 Use the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.

 Track every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.

 Use the web_fetch tool to retrieve the content of a specific HTTP(S) URL (for example a result from web_search). It returns the page content decoded to text. Cite the URL as a markdown link when you use its content.
 
 Use goal tools for one long-running completion objective in the current session. create_goal may infer goal intent from a direct human request in any language; do not create a goal for routine single-turn work. Call get_goal before update_goal and copy its exact goal_id and revision. After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.

-
 Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.
 
 Use the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.

 Track every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.
 
-Current DSH file policy: danger-full-access. The DSH file sandbox does not restrict the write and edit tools or one-shot bash commands.
-
 Use goal tools for one long-running completion objective in the current session. create_goal may infer goal intent from a direct human request in any language; do not create a goal for routine single-turn work. Call get_goal before update_goal and copy its exact goal_id and revision. After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.
 
-Approval prompts are disabled in this session: actions that require approval are rejected automatically — do not request sandbox escalation (do not set `sandbox_permissions`).

-
 Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.
 
 Use the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.

Keep answers brief and\nfactual.\n\n\nUse the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.\n\nUse the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.\n\nCheck the [exit code: N] marker on every bash result; investigate failures before moving on.\n\nUse a terminal session only when work needs persistent terminal state or interactive stdin; prefer bash/read/write/edit for bounded one-shot operations. Track every terminal session id and close sessions that no longer matter. An inferred_idle or timeout result does not prove the foreground command exited.\n\nTrack every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.\n\nUse the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn.\n\nThe workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn.\n\nThe workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

 **One readiness projection owns both Models and onboarding facts.** `ui-models` keeps a single store that joins `llm.providers({})`, redacted `settings.describe({})`, and batched `credentials.describe({refs})`. The onboarding projection selects the `deepseek-official` configurable-provider entry, resolves its `settingsNs` and `settingsPath`, reads the effective `apiKeyEnv`, and evaluates the matching credential descriptor.

+# Agent Note: Versioned GUI welcome onboarding
+
+Status: implemented
+
+English | [中文](2026-07-30-versioned-gui-welcome-onboarding.zh.md)
+
+## Problem
+
+The GUI's credential onboarding begins with a DeepSeek-specific readiness check, but the internal-test notice applies to every user and must precede provider setup even when a credential is already configured. Treating both as independent overlays permits simultaneous dialogs, while a process-local dismissal cannot distinguish a completed notice from a window closed before acknowledgement or intentionally present revised copy once.
+
+## Decision
+
+**The Settings shell coordinates ordered steps.** `settings.onboarding` remains a root-scoped list, but `ui-settings` projects its entry ids and order into one coordinator and mounts only the first incomplete step. The active registrant receives `complete()` and `openSection(id)`; no later step mounts until ownership transfers. The product welcome registers at order `-100`, while `ui-models` retains only the conditional DeepSeek readiness and credential-routing step at order `0`.
+
+**Ownerless product onboarding belongs to `ui-settings-general`.** `src/onboarding-copy.ts` is the single editable source for the complete Chinese notice, its faithful English counterpart, the Continue labels, and `WELCOME_NOTICE_VERSION`. Runtime locale dictionaries derive their welcome values from that file, and tests import the same owner instead of repeating paragraph text. The notice is browser UI only: it creates no Session event and contributes no model-visible content.
+
+**Acknowledgement is durable per Harness profile.** The Host half registers a `ui-onboarding` section in the user-settings seam, stored under the active `$DSH_HOME/settings.yaml`. The browser shows the notice unless `welcomeNoticeVersion` equals the owner constant exactly. Continue applies one path mutation with the current version and calls `complete()` only after the Host commits it; a failed write leaves the notice open, and closing the page or process writes nothing. Bumping the constant intentionally makes every profile acknowledge the revised copy once.
+
+**Concurrent views converge without stale replacement.** The acknowledgement write omits `expectedRevision` deliberately: every tab writes the same version to one path, so the operation is idempotent and preserves sibling fields instead of rebuilding the section. `settings/document-updated` becomes `host/settings-changed`; an already mounted tab refetches and advances when another tab or an external editor commits the current version. The API proxy exposes this one product namespace through a closed allowlist beside configurable-provider namespaces, without treating its changes as model-catalog invalidations.
+
+**The welcome modal has one completion path.** It renders no close icon or secondary action, installs no Escape handler, and assigns no click handler to the mask. Its mask starts below the 80 px top chrome and preserves `position:absolute`, zero left/right/bottom offsets, `rgba(0, 0, 0, 0.24)`, and `backdrop-filter: blur(2px)`. Continue is the sole button and receives initial focus.
+
+## Alternatives considered
+
+**Browser local storage** — rejected because acknowledgement would follow one browser profile rather than `$DSH_HOME`; a fresh Harness profile could incorrectly inherit a prior acknowledgement, and external profile edits would have no authoritative update stream.
+
+**A second independent modal in `ui-settings-general`** — rejected because list registrants would still stack whenever welcome and credential readiness were both true. Ordered ownership belongs to the shell that declares and renders the list.
+
+**Persisting on render or window close** — rejected because observation is not acknowledgement and close delivery is unreliable. Only the explicit Continue commit may suppress the next launch.
+
+**A generic public settings-exposure flag** — rejected because one product namespace does not justify widening every settings registrant's public configuration surface. The gateway keeps an explicit closed allowlist.
+
+## Consequences
+
+A fresh profile always sees the welcome notice before provider-specific onboarding; an already configured credential skips only the later DeepSeek step. Reloading after Continue stays past the acknowledged version, changing the owner version presents it again, and closing before Continue leaves the next launch unchanged. Focused store and React tests pin exact-version comparison, write failure, sole-action behavior, no-dismiss paths, coordinator ordering, conditional DeepSeek transfer, and HMR cleanup. The real Chromium scenario boots the shipped Web composition with an isolated harness home, verifies the exact mask geometry and computed styles, reloads before and after acknowledgement, continues into missing-credential setup, confirms an acknowledged-version mismatch returns while the credential is configured, and checks the browser console.

+# Agent Note: 版本化 GUI 欢迎引导
+
+Status: implemented
+
+[English](2026-07-30-versioned-gui-welcome-onboarding.md) | 中文
+
+## 问题
+
+GUI 的凭据引导从 DeepSeek 专用的就绪状态检查开始，但内部测试通知适用于每位用户，即使凭据已经配置，也必须先于提供方设置显示。若把两者作为独立浮层处理，多个对话框可能同时出现；仅存于进程内的关闭标记既无法区分通知已完成确认还是窗口在确认前已关闭，也无法在文案有意修订后重新显示一次通知。
+
+## 决策
+
+**设置外壳协调有序步骤。** `settings.onboarding` 仍是根作用域 list，但 `ui-settings` 会把其中各条目的 id 和顺序投影到一个协调器中，并且只挂载第一个未完成的步骤。当前注册方会收到 `complete()` 和 `openSection(id)`；所有权转移前，不会挂载后续步骤。产品欢迎步骤的顺序为 `-100`，`ui-models` 则只保留顺序为 `0` 的 DeepSeek 条件式就绪状态与凭据跳转步骤。
+
+**不属于单一功能的产品引导由 `ui-settings-general` 持有。** `src/onboarding-copy.ts` 是完整中文通知、忠实英文对侧文案、两种语言的「继续」按钮文案和 `WELCOME_NOTICE_VERSION` 的唯一可编辑来源。运行时 locale 字典从该文件派生欢迎文案，测试也导入同一个所有者，而不重复段落文本。该通知只存在于浏览器 UI：它不会创建会话事件，也不会贡献任何模型可见内容。
+
+**确认状态按 Harness profile 持久化。** 宿主端在 user-settings seam 中注册 `ui-onboarding` 分节，并存入当前 `$DSH_HOME/settings.yaml`。除非 `welcomeNoticeVersion` 与文案所有者文件中的常量精确相等，否则浏览器会显示通知。「继续」会以当前版本执行一次路径变更，并且仅在宿主端提交成功后调用 `complete()`；写入失败时通知保持打开，关闭页面或进程则不会写入任何内容。提升该常量会有意要求每个 profile 对修订后的文案重新确认一次。
+
+**并发视图无需陈旧的整体替换即可收敛。** 确认写入有意省略 `expectedRevision`：每个标签页都向同一路径写入相同版本，因此该操作是幂等的，并会保留同级字段，而不是重建整个分节。`settings/document-updated` 会转为 `host/settings-changed`；另一个标签页或外部编辑器提交当前版本后，已挂载的标签页会重新拉取状态并推进。API 网关在可配置提供方 namespace 之外，通过封闭的允许列表暴露这一个产品 namespace，同时不会把它的变更视为模型目录失效事件。
+
+**欢迎模态窗口只有一条完成路径。** 界面不渲染关闭图标或次要操作，不安装 Escape 处理器，也不为遮罩添加点击处理器。遮罩从顶部 80 px 的界面框架下方开始，并保留 `position:absolute`、left/right/bottom 偏移量为零、`rgba(0, 0, 0, 0.24)` 和 `backdrop-filter: blur(2px)`。「继续」是唯一按钮，并会获得初始焦点。
+
+## 曾考虑的替代方案
+
+**浏览器本地存储**：不予采用，因为确认状态会跟随某个浏览器 profile，而不是 `$DSH_HOME`；全新的 Harness profile 可能错误继承此前的确认状态，外部 profile 编辑也没有权威更新流。
+
+**在 `ui-settings-general` 中再增加一个独立模态窗口**：不予采用，因为欢迎通知和凭据就绪状态同时为真时，list 注册方仍会堆叠。声明并渲染该 list 的外壳应当持有有序所有权。
+
+**在渲染或窗口关闭时持久化**：不予采用，因为看见通知不等于确认，窗口关闭事件也无法可靠送达。只有显式提交「继续」才能阻止通知在下次启动时再次显示。
+
+**通用的公开设置暴露标志**：不予采用，因为一个产品 namespace 不足以证明应当扩大每个 settings 注册方的公开配置面。网关保留显式的封闭允许列表。
+
+## 后果
+
+全新 profile 始终会在提供方专用引导之前看到欢迎通知；凭据已经配置时，只会跳过后续 DeepSeek 步骤。点击「继续」后重新加载不会再次显示已确认版本，更改文案所有者文件中的版本值会让通知重新出现，而确认前关闭窗口不会改变下次启动。针对性的 store 与 React 测试固化了精确版本比较、写入失败、单一操作、不可关闭路径、协调器顺序、按条件移交 DeepSeek 步骤和 HMR（热模块替换）清理行为。真实 Chromium 场景会使用隔离的 harness 家目录启动随产品提供的 Web 组合，验证遮罩的精确几何尺寸和计算样式，在确认前后分别重新加载，继续进入凭据缺失设置流程，确认凭据已配置时确认版本不匹配仍会使通知重新出现，并检查浏览器控制台。

-Models settings plugin: the provider configuration page and official-DeepSeek first-run routing overlay. It joins three wire domains into one shared snapshot — `llm.providers` (the configurable-provider directory with each route's live/dormant state), `settings.describe` (serialized schemas, layered redacted values, secret slots), and `credentials.describe` (value-free configured/source/writable badges) — and renders provider rows with one editor card at a time.
+Models settings plugin: the provider configuration page and official-DeepSeek conditional onboarding step. It joins three wire domains into one shared snapshot — `llm.providers` (the configurable-provider directory with each route's live/dormant state), `settings.describe` (serialized schemas, layered redacted values, secret slots), and `credentials.describe` (value-free configured/source/writable badges) — and renders provider rows with one editor card at a time.
 
 Rows are the *configured* providers (their profile resolves in the owning namespace); a whole-section provider whose key is not configured anywhere (the first-run DeepSeek posture) renders as its open setup card instead of a row, and the add flow is a card carrying the dormant-directory provider select — a bare-mounted `llm-pi-ai` offers its whole installed catalog before any route exists. The editor is a hand-written card per adapter family: the primary field is a single **API key** input — the page never asks for an environment-variable name; a typed key stores **write-only** through `credentials.set` under the profile's reference, deriving `_API_KEY` when the profile has none, and the pi-ai profile records that derivation as `apiKeyEnv`, so `settings.yaml` never carries a key value. The collapsed 自定义设置 fold carries the curated extras — `baseURL` for both families (the deepseek placeholder shows the public endpoint), plus `reasoningEffort` (deepseek) or `reasoning` (pi-ai); every other profile field stays owned by `settings.yaml`. A row is deletable only when the user layer alone carries it (removal restores the composition base).
 
-The first-run overlay projects `deepseek-official` readiness from that same joined snapshot. A configured literal `apiKey` secret sidecar or configured credential reference suppresses the prompt, including a read-only launch-environment credential. A mounted adapter with a missing writable reference shows one action that opens Settings on the Models section, whose existing setup card exclusively owns key input and `credentials.set`; the overlay never holds a secret. An absent adapter is skipped because browser navigation cannot mount Cordis plugins, while an unusable settings or credential capability produces a deployment diagnostic with the same route to Models.
+The DeepSeek step projects `deepseek-official` readiness from that same joined snapshot after earlier onboarding steps complete. A configured literal `apiKey` secret sidecar or configured credential reference completes the step without rendering, including a read-only launch-environment credential. A mounted adapter with a missing writable reference shows one action that opens Settings on the Models section, whose existing setup card exclusively owns key input and `credentials.set`; the step never holds a secret. An absent adapter is skipped because browser navigation cannot mount Cordis plugins, while an unusable settings or credential capability produces a deployment diagnostic with the same route to Models.
 
 Every edit lands as `settings.mutate` path ops against the stored section — a set per changed field, an unset per cleared one, and a single unset for a deleted row. The page only ever holds the REDACTED descriptor, so it names the fields it can see rather than rebuilding a section: a stored literal secret it never received is mentioned by no op and survives. Each write carries the `revision` the card opened at, so a concurrent write from another tab or an external `settings.yaml` edit is refused as `settings-conflict` and the card asks the user to reopen instead of replaying its stale snapshot. The page refetches on the pushed invalidations (`settings/changed`, `credentials/changed`, `models/changed`, and `connection/reset`) once it has loaded, so an external `settings.yaml` edit, a second tab, or a settings-born route converges without polling.

-模型设置插件：提供方配置页和 DeepSeek 官方首次使用跳转浮层。它把三个协议领域汇聚为一个共享快照：`llm.providers`（可配置提供方目录，含每条路由的存活／休眠状态）、`settings.describe`（序列化 schema、分层脱敏值、secret 槽位）与 `credentials.describe`（不含值的 configured/source/writable 徽标）；页面据此渲染提供方行，一次只展开一张编辑卡片。
+模型设置插件：提供方配置页和按条件显示的 DeepSeek 官方首次使用引导步骤。它把三个协议领域汇聚为一个共享快照：`llm.providers`（可配置提供方目录，含每条路由的存活／休眠状态）、`settings.describe`（序列化 schema、分层脱敏值、secret 槽位）与 `credentials.describe`（不含值的 configured/source/writable 徽标）；页面据此渲染提供方行，一次只展开一张编辑卡片。
 
 行是*已配置*的提供方（其 profile 在所属 namespace 中解析得出）；密钥未在任何地方配置的整分节提供方（DeepSeek 的首次运行姿态）会渲染为其展开的设置卡片而非一行，「新增」流程则是一张承载休眠目录提供方选择框的卡片——裸挂载的 `llm-pi-ai` 在任何路由存在之前就能提供其完整的已安装 catalog。编辑器是每个适配器家族各一张的手写卡片：主字段是单独一个 **API 密钥**输入框——页面从不询问环境变量名；键入的密钥经 `credentials.set` 以**只写**方式存入 profile 的引用之下，profile 没有引用时便派生 `_API_KEY`，pi-ai profile 会把这次派生记录为 `apiKeyEnv`，因此 `settings.yaml` 从不携带密钥值。收起的「自定义设置」折叠区承载精选的额外字段——两个家族都有 `baseURL`（deepseek 的占位符显示公共端点），另加 `reasoningEffort`（deepseek）或 `reasoning`（pi-ai）；其余每个 profile 字段仍归 `settings.yaml` 所有。只有当某行仅由用户层承载时它才可删除（删除会还原组合 base）。
 
-首次使用浮层从同一个联接快照得出 `deepseek-official` 的就绪状态。若 `apiKey` 字面量对应的 secret 槽位标记为已设置，或凭据引用已配置，浮层就不再显示，其中包括来自启动环境且只读的凭据。适配器已挂载、引用可写但尚未配置时，浮层只显示一个操作按钮，用于打开「设置」的 Models 分区；密钥输入和 `credentials.set` 仅由该分区已有的设置卡片负责，浮层绝不持有 secret。适配器缺失时直接跳过，因为浏览器导航无法挂载 Cordis 插件；设置或凭据能力不可用时则显示部署诊断，并提供同一个前往 Models 的入口。
+前序首次使用引导步骤完成后，DeepSeek 步骤会从同一个联接快照得出 `deepseek-official` 的就绪状态。若 `apiKey` 字面量对应的 secret 槽位标记为已设置，或凭据引用已配置，该步骤会直接完成而不渲染，其中包括来自启动环境且只读的凭据。适配器已挂载、引用可写但尚未配置时，该步骤只显示一个操作按钮，用于打开「设置」的 Models 分区；密钥输入和 `credentials.set` 仅由该分区已有的设置卡片负责，该步骤绝不持有 secret。适配器缺失时直接跳过，因为浏览器导航无法挂载 Cordis 插件；设置或凭据能力不可用时则显示部署诊断，并提供同一个前往 Models 的入口。
 
 每一次编辑都以 `settings.mutate` 的路径 op 落到已存分节上——每个变更字段一条 set、每个清空字段一条 unset、删除整行则是单独一条 unset。页面自始至终只持有**脱敏后**的 descriptor，因此它点名自己看得见的字段，而不是重建分节：一个它从未收到过的已存字面机密不会被任何 op 提及，也就得以留存。每次写入都携带该卡片打开时的 `revision`，因此来自另一个标签页或对 `settings.yaml` 的外部编辑所产生的并发写入会以 `settings-conflict` 被拒绝，卡片会请用户重新打开，而不是把自己的陈旧快照重放上去。页面加载完成后会在推送的失效事件（`settings/changed`、`credentials/changed`、`models/changed` 与 `connection/reset`）上重拉，因此外部的 `settings.yaml` 编辑、第二个标签页或 settings 新生的路由都无需轮询即可收敛。

Feature-owned rows (Language, Appearance), sections (Models), and conditional onboarding steps stay with their feature packages.
+
+`src/onboarding-copy.ts` is the single editable owner of the complete Chinese and English notice plus `WELCOME_NOTICE_VERSION`. The Host half registers `ui-onboarding` in the user-settings seam; the browser compares `welcomeNoticeVersion` for exact equality and writes the current value only after Continue succeeds. The path mutation is idempotent across tabs and preserves sibling settings, while `host/settings-changed` makes an externally acknowledged notice advance without a reload. A different version deliberately presents the notice again. The welcome UI has no close, Escape, mask-click, or secondary path, and none of its copy or acknowledgement enters a Session log or model request.

+`src/onboarding-copy.ts` 是完整中英文通知文案和 `WELCOME_NOTICE_VERSION` 的唯一可编辑来源。宿主端在 user-settings seam 中注册 `ui-onboarding`；浏览器比较 `welcomeNoticeVersion` 是否精确相等，仅在「继续」操作成功后写入当前值。该路径变更在不同标签页间幂等，并会保留同级设置；`host/settings-changed` 则让页面在通知被外部确认后，无需重新加载即可推进。版本不同时，系统会有意重新显示通知。欢迎界面没有关闭操作、Escape、点击遮罩或次要操作路径，其文案和确认状态均不会进入会话日志或模型请求。

-Settings shell plugin: a pure composition face. It occupies `sidebar.settings` with the trigger chrome and modal settings panel, and declares the slots registrants fill: `settings.trigger` / `settings.header` / `settings.close` (chrome content), `settings.section` (one page per feature), and `settings.onboarding` (feature-owned overlays on the empty Hero).

+Settings shell plugin: a pure composition face. It occupies `sidebar.settings` with the trigger chrome and modal settings panel, and declares the slots registrants fill: `settings.trigger` / `settings.header` / `settings.close` (chrome content), `settings.section` (one page per feature), and `settings.onboarding` (ordered feature-owned steps on the empty Hero). The shell ships no copy and reads no locale state — all text arrives from registrants (ui-settings-general owns chrome, General, and the product welcome step; features own their sections, rows, and conditional onboarding steps).
 
-The shell supplies onboarding registrants only two navigation facts: whether the session surface is the empty Hero and an `openSection(id)` callback that opens the panel on a registered section. Registrants own capability readiness, dismissal, copy, and mutations; the shell therefore does not become a second configuration fact source.
+The shell projects the onboarding ledger into ascending order and mounts exactly one step at a time. The active registrant receives its id, `complete()`, and an `openSection(id)` callback; completing or skipping transfers ownership to the next entry. Registrants own durable completion, capability readiness, copy, and mutations, so two independently registered dialogs cannot stack and the shell does not become a second configuration fact source.

+外壳将首次使用引导记录按升序投影，并且每次只挂载一个步骤。当前注册方会收到该条目的 id、`complete()` 和 `openSection(id)` 回调；完成或跳过当前步骤后，所有权转交给下一项。持久化完成状态、能力就绪状态、文案和变更操作均由注册方持有，因此两个独立注册的对话框无法堆叠，外壳也不会成为第二个配置事实来源。

Every method addresses one session's agent by `sessionId` (a served session always has an Agent; `command.*` resumes cold sessions through the same path as `session.*`, while `skill.list` resolves the project root from the session header without touching the Agent registry). `skill.list` serves the browser's user-selected model-reference path, so it returns only skills that are both model-invocable and user-invocable; this domain has no direct skill-loading RPC. `command.execute` runs a slash-command line host-side with pure admission semantics: the response reports whether the line resolved to a handler plus the minted lifecycle `commandId` when it did (correlating the acknowledgment with the flow node), while the outcome rides the durably logged `command/run`/`command/done` lifecycle pair broadcast on the mux stream; the carrier's request signal cancels the running handler. `host/commands-changed` is the catalog invalidation frame: clients refetch `command.list` instead of diffing.

Any write may carry `expectedRevision`; a stale one answers `settings-conflict` with both revisions rather than overwriting the writer that landed first, and every other seam refusal folds into `settings-rejected`.

 Both positive controls therefore failed the pre-registered sensitivity gate. The formal twelve-session Candidate A and B arms were not run, and these experiments do not select or validate the current wording. They establish that the earlier five-of-twelve result is not reproducible under this task and current tool guidance, and that a stronger positive control or different task distribution is required before making model-behavior rate claims. Deterministic tests below establish truthful request construction and replay only.
 
-The cache-safe delivery rework then supplied a separate, non-statistical acceptance comparison over the neutral Web task `Create the relative path policy-neutral.txt ...`; it does not replace the pre-registered twelve-session experiment. Candidate A's categorical read-only statement produced a text refusal with zero tool calls. Candidate B added one composition-conditioned sentence only for enforced families whose tools expose escalation. A fresh real-provider run then issued an ordinary `write`, observed the read-only denial, retried the same operation in the same turn with `sandbox_permissions: "workspace-write"`, received approval, read the file back, and verified the exact contents. It made no speculative escalation. Across the permission switches and four mutation steps, cache reads were 14,848–15,872 tokens while uncached input was 59–251 tokens per request, directly demonstrating the stable-prefix benefit.

The following skills are available in this session:\n\n\n- `15-05-premortem`: Use before starting risky work — rebases, large refactors, multi-file migrations, or deploys — to identify failure modes and mitigations in advance.\n- `acceptance-criteria`: 检查Acceptance Criteria格式和完整性，验证是否符合Given-When-Then结构、覆盖正常流程/边界条件/异常场景。适合在为User Story编写AC后、准备测试用例前使用，当需要验收AC质量时。帮助不熟悉BDD的PM/BA确保AC明确、可测试、覆盖完整，避免遗漏关键场景。\n- `agents-sdk`: Build AI agents on Cloudflare Workers using the Agents SDK. Load when creating stateful agents, durable workflows, real-time WebSocket apps, scheduled tasks, MCP servers, chat applications, voice agents, or browser automation. Covers Agent class, state management, callable RPC, Workflows, durable execution, queues, retries, observability, and React hooks. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.\n- `aico-pm-user-story-writing`: Transform requirements into well-structured User Stories using \"As a [user], I want [goal], So that [benefit]\" format with Given/When/Then acceptance criteria. Use this skill when: - User asks to \"write user story\", \"create story\", \"add story\" - User mentions \"user story\", \"backlog item\", \"story\" - Running /pm.plan and need to break PRD into implementable stories - Creating backlog items for development team - Need to formalize a requirement into standard story format - Converting feature req...\n- `algorithmic-art`: Creating algorithmic art using p5.js with seeded randomness and interactive parameter exploration. Use this when users request creating art using code, generative art, algorithmic art, flow fields, or particle systems. Create original algorithmic art rather than copying existing artists' work to avoid copyright violations.\n- `animation-vocabulary`: Reverse-lookup glossary that turns a vague description of a web animation or motion effect into its exact term (\"the bouncy thing when a popover opens\" → Pop in; \"the iOS rubber-band scroll\" → Rubber-banding). Use when the user asks \"what's it called when…\", or describes a motion effect without knowing its name and wants the right word to prompt an AI or designer with. For naming an effect, not designing or building one.\n- `app-comprehensive-test-generator`: Generate exhaustive user-flow and edge-case test scenarios from an app's codebase, produce scenario .md files, execute tests using connected or newly created MCPs, and produce an app.qa.report.md summarizing failures and suggested fixes.\n- `apple-design`: Apple's approach to interface design and fluid, physical motion, translated for the web. Use when building or reviewing gesture-driven UI, spring animations, drag/swipe/sheet interactions, momentum and interruptible transitions, translucent materials and depth, typography (optical sizing, tracking, leading), reduced-motion, or the design foundations (feedback, spatial consistency, restraint) behind Apple-style interfaces.\n- `brainstorming`: You MUST use this before any creative work - creating features, building components, adding functionality, or modifying behavior. Explores user intent, requirements and design before implementation.\n- `brand-guidelines`: Applies Anthropic's official brand colors and typography to any sort of artifact that may benefit from having Anthropic's look-and-feel. Use it when brand colors or style guidelines, visual formatting, or company design standards apply.\n- `canvas-design`: Create beautiful visual art in .png and .pdf documents using design philosophy. You should use this skill when the user asks to create a poster, piece of art, design, or other static piece. Create original visual designs, never copying existing artists' work to avoid copyright violations.\n- `claude-api`: Reference for the Claude API / Anthropic SDK — model ids, pricing, params, streaming, tool use, MCP, agents, caching, token counting, model migration. TRIGGER — read BEFORE opening the target file; don't skip because it \"looks like a one-liner\" — whenever: the prompt names Claude/Anthropic in any form (Claude, Anthropic, Fable, Opus, Sonnet, Haiku, `anthropic`, `@anthropic-ai`, `claude-*`, `us.anthropic.*`, `[1m]`); the user asks about an LLM (pricing/model choice/limits/caching) — never answ...\n- `cloudflare`: Comprehensive Cloudflare platform skill covering Workers, Pages, storage (KV, D1, R2), AI (Workers AI, Vectorize, Agents SDK), feature flags (Flagship), networking (Tunnel, Spectrum), security (WAF, DDoS), and infrastructure-as-code (Terraform, Pulumi). Use for any Cloudflare development task. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.\n- `cloudflare-email-service`: Send and receive transactional emails with Cloudflare Email Service (Email Sending + Email Routing). Use when building email sending (Workers binding or REST API), email routing, Agents SDK email handling, or integrating email into any app — Workers, Node.js, Python, Go, etc. Also use for email deliverability, SPF/DKIM/DMARC, wrangler email setup, MCP email tools, or when a coding agent needs to send emails.

Mirrors developers.cloudflare.com/turnstile/spin.\n- `web-artifacts-builder`: Suite of tools for creating elaborate, multi-component claude.ai HTML artifacts using modern frontend web technologies (React, Tailwind CSS, shadcn/ui). Use for complex artifacts requiring state management, routing, or shadcn/ui components - not for simple single-file HTML/JSX artifacts.\n- `web-perf`: Analyzes web performance using Chrome DevTools MCP. Measures Core Web Vitals (LCP, INP, CLS) and supplementary metrics (FCP, TBT, Speed Index), identifies render-blocking resources, network dependency chains, layout shifts, caching issues, and accessibility gaps. Use when asked to audit, profile, debug, or optimize page load performance, Lighthouse scores, or site speed. Biases towards retrieval from current documentation over pre-trained knowledge.\n- `webapp-testing`: Toolkit for interacting with and testing local web applications using Playwright. Supports verifying frontend functionality, debugging UI behavior, capturing browser screenshots, and viewing browser logs.\n- `workers-best-practices`: Reviews and authors Cloudflare Workers code against production best practices. Load when writing new Workers, reviewing Worker code, configuring wrangler.jsonc, or checking for common Workers anti-patterns (streaming, floating promises, global state, secrets, bindings, observability). Biases towards retrieval from Cloudflare docs over pre-trained knowledge.\n- `wrangler`: Cloudflare Workers CLI for deploying, developing, and managing Workers, KV, R2, D1, Vectorize, Hyperdrive, Workers AI, Containers, Queues, Workflows, Pipelines, and Secrets Store. Load before running wrangler commands to ensure correct syntax and best practices. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.\n- `xlsx`: Use this skill any time a spreadsheet file is the primary input or output. This means any task where the user wants to: open, read, edit, or fix an existing .xlsx, .xlsm, .csv, or .tsv file (e.g., adding columns, computing formulas, formatting, charting, cleaning messy data); create a new spreadsheet from scratch or from other data sources; or convert between tabular file formats. Trigger especially when the user references a spreadsheet file by name or path — even casually (like \"the xlsx in...\n- `zotero-library-curator`: Audit and curate a Zotero library — find duplicate DOIs, orphan items missing required tags, propose collection rebinds, identify bloated or under-used collections, generate tag hygiene reports, emit preview-only cleanup plans. Use when the user asks to \"audit Zotero\", \"find duplicates\", \"tag hygiene report\", \"which collections are bloated or under-used\", or \"propose a Zotero cleanup plan\". Defers all CRUD operations to the standalone `zotero-skills` skill or `research-hub zotero` CLI. Includ...\n\n\nIf the user names a skill, or the task clearly matches a skill's description, call the `skill` tool with the exact skill name before taking task actions. Load all applicable skills, then follow their full instructions. This catalog contains summaries only; do not infer or follow a skill's instructions until it has been loaded.\n"}],"source":{"kind":"plugin","plugin":"dsh-tool-skill"},"role":"user","id":"99ab4893-10ee-4c69-b9dc-ff46ccba6026"},"surfaceOp":"append"}

Use when the user asks to \"orient me in this project\", \"what is this repo about\", or \"build a context map for this paper\" — and the project already has .research/ manifests (or trigger research-context-compressor first).\n- `research-report`: 将deep调研结果汇总为markdown报告，覆盖所有字段，跳过不确定值。\n- `research-session-management`: Use when starting or ending any thesis writing session — manages INDEX files, handoff documents, and startup/shutdown protocols for cross-session continuity. Triggers on 'new thesis session', 'session handoff', 'continue thesis work', 'pick up where left off', 'end session'.\n- `research-style-audit`: Use after completing any thesis section draft — runs programmatic style audit to catch Pattern\n- `research-task-file`: Use when creating self-contained task files for autonomous AI agent execution — goal-oriented instructions with context, decision frameworks, and validation criteria. Triggers on 'create task file', 'autonomous task', 'agent task', 'data extraction task', 'TASK file', 'batch processing task'.\n- `research-three-stage-review`: Use after completing a thesis prose draft — runs three independent review stages with different perspectives and information access. Triggers on 'review draft', 'check section', 'draft review', 'quality check', 'before sending to advisor'.\n- `research-writing`: Use when starting any academic thesis or dissertation writing task — routes to the correct thesis sub-skill based on the current phase of work. Triggers on 'thesis', 'dissertation', 'chapter writing', 'section writing', 'defense prep', 'academic writing with AI'.\n- `research-writing-brief`: Use when planning any thesis section before writing prose — creates a Writing Brief with boundary rules, internalization check, verified data table, and paragraph-level outline with argumentative purposes. Triggers on 'plan section', 'write section X.Y', 'prepare to write', 'writing brief', 'section outline'.\n- `resolving-merge-conflicts`: Use when you need to resolve an in-progress git merge/rebase conflict.\n- `sandbox-sdk`: Build sandboxed applications for secure code execution. Load when building AI code execution, code interpreters, CI/CD systems, interactive dev environments, or executing untrusted code. Covers Sandbox SDK lifecycle, commands, files, code interpreter, and preview URLs. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.\n- `scheduled-task-planner`: 分析定时任务需求，确定最优部署方案（Cloudflare Worker 或本地 launchd）\n- `sequential-thinking`: Structured reflective problem-solving methodology. Process: decompose, analyze, hypothesize, verify, revise. Capabilities: complex problem decomposition, adaptive planning, course correction, hypothesis verification, multi-step analysis. Actions: decompose, analyze, plan, revise, verify solutions step-by-step. Keywords: sequential thinking, problem decomposition, multi-step analysis, hypothesis verification, adaptive planning, course correction, reflective thinking, step-by-step, thought sequ...\n- `skill-creator`: Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, edit, or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.\n- `slack-gif-creator`: Knowledge and utilities for creating animated GIFs optimized for Slack. Provides constraints, validation tools, and animation concepts. Use when users request animated GIFs for Slack like \"make me a GIF of X doing Y for Slack.\"\n- `tdd`: Test-driven development. Use when the user wants to build features or fix bugs test-first, mentions \"red-green-refactor\", or wants integration tests.\n- `test`: Test features before users find bugs. Use when feature is built, before deploying, or when bugs reported. Covers manual testing, edge cases, cross-browser testing, and testing checklists for non-technical founders.\n- `theme-factory`: Toolkit for styling artifacts with a theme. These artifacts can be slides, docs, reportings, HTML landing pages, etc. There are 10 pre-set themes with colors/fonts that you can apply to any artifact that has been creating, or can generate a new theme on-the-fly.\n- `turnstile-spin`: Set up Cloudflare Turnstile end-to-end in a project — scan the codebase, create the widget via the Cloudflare API, deploy the managed siteverify Worker, write the frontend snippets, validate, and persist the skill. Load this when a user asks to add Turnstile, set up CAPTCHA, protect a form from bots, or fix a Turnstile integration. Mirrors developers.cloudflare.com/turnstile/spin.\n- `web-artifacts-builder`: Suite of tools for creating elaborate, multi-component claude.ai HTML artifacts using modern frontend web technologies (React, Tailwind CSS, shadcn/ui). Use for complex artifacts requiring state management, routing, or shadcn/ui components - not for simple single-file HTML/JSX artifacts.\n- `web-perf`: Analyzes web performance using Chrome DevTools MCP. Measures Core Web Vitals (LCP, INP, CLS) and supplementary metrics (FCP, TBT, Speed Index), identifies render-blocking resources, network dependency chains, layout shifts, caching issues, and accessibility gaps.

Biases towards retrieval from Cloudflare docs over pre-trained knowledge.\n- `wrangler`: Cloudflare Workers CLI for deploying, developing, and managing Workers, KV, R2, D1, Vectorize, Hyperdrive, Workers AI, Containers, Queues, Workflows, Pipelines, and Secrets Store. Load before running wrangler commands to ensure correct syntax and best practices. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.\n- `xlsx`: Use this skill any time a spreadsheet file is the primary input or output. This means any task where the user wants to: open, read, edit, or fix an existing .xlsx, .xlsm, .csv, or .tsv file (e.g., adding columns, computing formulas, formatting, charting, cleaning messy data); create a new spreadsheet from scratch or from other data sources; or convert between tabular file formats. Trigger especially when the user references a spreadsheet file by name or path — even casually (like \"the xlsx in...\n- `zotero-library-curator`: Audit and curate a Zotero library — find duplicate DOIs, orphan items missing required tags, propose collection rebinds, identify bloated or under-used collections, generate tag hygiene reports, emit preview-only cleanup plans. Use when the user asks to \"audit Zotero\", \"find duplicates\", \"tag hygiene report\", \"which collections are bloated or under-used\", or \"propose a Zotero cleanup plan\". Defers all CRUD operations to the standalone `zotero-skills` skill or `research-hub zotero` CLI. Includ...\n\n\nIf the user names a skill, or the task clearly matches a skill's description, call the `skill` tool with the exact skill name before taking task actions. Load all applicable skills, then follow their full instructions.

Subject: [PATCH 096/557] docs: generate THIRD_PARTY_NOTICES.md and gate it in
 doc-sync

Replace the hand-written inventory with scripts/gen-third-party-notices.ts,
verified fresh by a doc-sync leaf gate. Tier by declaring workspace area
rather than manifest section, so test-support runtime declarations stay
dev-only and every mountable plugin's dependencies are disclosed as
runtime; list the pnpm-patched packages; point the Python closure at
uv.lock. Re-record the translation-prompt snapshot the README link
invalidated.

+# Agent Note: Generated third-party notices
+
+Status: implemented

+
+## Problem
+
+Open-sourcing this repository requires disclosing the third-party software it depends on, with each project's license. The disclosure has to be complete, has to stay true as dependencies change, and has to say something a reader can act on — which of these packages end up on a user's machine, and which only build and test the repository.
+
+A hand-written inventory answers none of those durably. Roughly a hundred rows of names and license strings derived from manifests drift silently the moment a package is added, removed, or relicensed, and nothing in `doc-sync` would notice.
+
+## Decision
+
+[`THIRD_PARTY_NOTICES.md`](../../../../THIRD_PARTY_NOTICES.md) is generated by [`scripts/gen-third-party-notices.ts`](../../../../scripts/gen-third-party-notices.ts) from the workspace manifests, `vendor/README.md`, the `pyproject.toml` files, and `pnpm-workspace.yaml`. `pnpm run verify-third-party-notices` runs the generator with `--check` as a `doc-sync` leaf gate, so a dependency change that skips regeneration fails the same way a stale catalog does. The root README pair links the file from its License section.
+
+The file discloses **direct** dependencies only. The complete npm closure with pinned versions already lives in `pnpm-lock.yaml` (`pnpm licenses list` renders it) and the Python closure in `python/sdk/uv.lock`; re-materializing either as prose would be a second, worse copy.
+
+**Tiering is by declaring area, not by manifest section.** A package is a runtime dependency when any manifest outside `DEV_ONLY_AREAS` — the root manifest, `packages/support/`, `packages/client/test-runtime/`, `website/`, `examples/`, `native/` — names it under `dependencies` or `optionalDependencies`. Section names alone are wrong in both directions: a test-support package declares `vitest` under `dependencies` without shipping it, and the `bin/dsh` launcher execs through `tsx`, which no manifest declares as a runtime dependency at all (the generator marks it runtime explicitly).
+
+The runtime tier deliberately covers **every mountable plugin**, not just what the CLI, Web UI, and Python runtime load by default. `scripts/install.sh` installs the repository itself, so a user's `cordis.yml` can mount any plugin package; `@modelcontextprotocol/sdk` and the OpenTelemetry packages reach real users even though no default assembly imports them. Under-disclosure is the costly direction for a legal notice.
+
+License and repository metadata come from the installed pnpm store, so the generator requires an installed tree and fails loud when a package resolves to neither, rather than emitting an empty cell. `OVERRIDES` carries the packages whose published manifest cannot answer — Rust-built npm bins that omit `license`, and the `modelcontextprotocol/servers` packages whose repository is mid MIT→Apache-2.0 relicensing, so their effective terms are per-contribution. Vendored packages are cross-checked against `vendor/README.md` and rejected if any is not MIT, and `pnpm-workspace.yaml`'s `patchedDependencies` are listed under the runtime table because pnpm applies those patches at install time — shipped artifacts carry modified copies of `@earendil-works/pi-tui` and `node-pty`, and the patch files are the record of what changed.
+
+## Testing
+
+[`scripts/gen-third-party-notices.spec.ts`](../../../../scripts/gen-third-party-notices.spec.ts) pins the tiering rule against fixture manifests — including the two cases that motivate it, a `dependencies` entry of a test-support package and a plugin package no app mounts — and pins that the vendored-table parser reads the committed manifest and yields nothing when the table shape changes, which is what makes the generator fail loud rather than emit an empty section.
+
+## Alternatives considered
+
+**Keep the hand-written file and review it at release time.** Reviewing a hundred derived rows by eye is exactly the work a generator does correctly, and the file's own claim — that it lists every direct dependency — would be unverified between releases.
+
+**Enumerate the full transitive closure.** The closure is thousands of packages, already recorded in the lock files with exact versions, and would bury the direct dependencies that a reader actually evaluates. The file points at the lock files and the `pnpm licenses list` renderer instead.
+
+**Tier by manifest section (`dependencies` vs `devDependencies`).** Mechanically simple and wrong on real data in both directions, as the tiering paragraph above records.
+
+**Tier by reachability from the shipped assemblies only** (`apps/*` plus `python/sdk-runtime`). This produces a tighter runtime tier, but classifies the MCP client and the OpenTelemetry exporter as development-only even though a user running the installed repository can mount them. It understates the disclosure, which is the wrong direction to err for a legal notice.
+
+**Emit the notices as a bilingual pair.** Every other root document is paired, but the file is a table of upstream package names, SPDX identifiers, and URLs; the translatable surface is a handful of section blurbs. `scripts/translation-pairing.ts` scopes discovery to `README*`, `.agents/notes/**`, `docs/**`, and `python/**`, so a root non-README file is outside the bilingual corpus by construction, and the README pair carries the bilingual entry points into it.
+
+## Consequences
+
+Adding or removing a dependency now requires running `pnpm run gen-third-party-notices` and committing the result; `doc-sync` fails otherwise. That is the intended cost — the disclosure cannot silently go stale.
+
+The generator needs an installed tree, which makes it heavier than a pure-source generator, and a new package with unusable published metadata needs an `OVERRIDES` entry rather than silently rendering a blank license. Both failures are loud and name the remedy.
+
+The tiering rule is a policy encoded in one constant. Adding a workspace area that never ships — a second test-infrastructure tier, another site — requires extending `DEV_ONLY_AREAS`, or its dependencies will be disclosed as runtime.

+
+## Problem
+
+本仓库开源需要披露所依赖的第三方软件及各自的许可证。这份披露必须完整，必须随依赖变化保持为真，还必须给出读者用得上的信息：哪些包最终会进到用户机器上，哪些只用于构建和测试。
+
+手写清单无法长期满足其中任何一条。约一百行从各清单文件推导出来的包名与许可证标识，只要有依赖新增、移除或换用许可证就会悄悄失真，而 `doc-sync` 不会察觉。
+
+## Decision
+
+[`THIRD_PARTY_NOTICES.md`](../../../../THIRD_PARTY_NOTICES.md) 由 [`scripts/gen-third-party-notices.ts`](../../../../scripts/gen-third-party-notices.ts) 依据各工作区清单、`vendor/README.md`、`pyproject.toml` 与 `pnpm-workspace.yaml` 生成。`pnpm run verify-third-party-notices` 以 `--check` 运行生成器，作为 `doc-sync` 的叶子门禁；依赖变了却没重新生成，会像目录过期一样直接失败。根 README 双语两侧都从「许可证」一节链到该文件。
+
+文件只披露**直接**依赖。完整的 npm 闭包连同锁定版本已记录在 `pnpm-lock.yaml`（`pnpm licenses list` 可渲染），Python 闭包记录在 `python/sdk/uv.lock`；再用散文誊一遍只会得到一份更差的副本。
+
+**分层依据是声明方所在区域，而非清单字段名。** 只要 `DEV_ONLY_AREAS` 之外的任一清单——即根清单、`packages/support/`、`packages/client/test-runtime/`、`website/`、`examples/`、`native/` 之外——在 `dependencies` 或 `optionalDependencies` 里点名某个包，它就是运行时依赖。单看字段名在两个方向上都会出错：测试支撑包把 `vitest` 写在 `dependencies` 里却并不交付它；而 `bin/dsh` 启动器 exec 经过的 `tsx`，根本没有任何清单把它声明为运行时依赖，只能由生成器显式标记。
+
+运行时层刻意覆盖**所有可挂载的插件**，而不止 CLI、Web UI 与 Python 运行时默认加载的那些。`scripts/install.sh` 安装的就是仓库本身，用户的 `cordis.yml` 可以挂载任何插件包；`@modelcontextprotocol/sdk` 与 OpenTelemetry 系列即使没有任何默认装配引入，也会触达真实用户。对法务披露而言，披露不足才是代价更高的那个方向。
+
+许可证与仓库地址取自已安装的 pnpm store，因此生成器要求工作树已安装依赖；某个包两处都解析不到时直接失败，而不是留下空单元格。`OVERRIDES` 收录已发布清单答不上来的包：用 Rust 构建、发布时省略 `license` 字段的 npm 可执行包，以及 `modelcontextprotocol/servers` 系列——该仓库正处在 MIT 向 Apache-2.0 的重新许可过程中，实际条款按贡献逐条而定。被源码收编的包会与 `vendor/README.md` 交叉核对，出现非 MIT 即报错；`pnpm-workspace.yaml` 的 `patchedDependencies` 列在运行时表格之后，因为 pnpm 在安装期就会打上这些补丁——交付产物携带的是改动过的 `@earendil-works/pi-tui` 与 `node-pty`，补丁文件本身就是改动的完整记录。
+
+## Testing
+
+[`scripts/gen-third-party-notices.spec.ts`](../../../../scripts/gen-third-party-notices.spec.ts) 用夹具清单钉住分层规则，覆盖促成该规则的两个场景：测试支撑包的 `dependencies` 条目，以及没有任何应用挂载的插件包。它同时钉住被收编包的表格解析器能读出已提交的清单表，且表格形态一变就解析为空——正是这一点让生成器直接失败，而不是产出一个空章节。
+
+## Alternatives considered
+
+**保留手写文件，发版时人工过一遍。** 用肉眼审阅上百行推导数据，恰恰是生成器能做对的活；而且在两次发版之间，文件自称「列出全部直接依赖」这句话无人验证。
+
+**列出完整传递闭包。** 闭包有数千个包，锁文件里已带精确版本，铺开只会淹没读者真正要评估的直接依赖。文件转而指向锁文件与 `pnpm licenses list`。
+
+**按清单字段分层（`dependencies` 与 `devDependencies`）。** 机械上最省事，但在真实数据上两个方向都会出错，理由见上文分层段落。
+
+**只按已交付装配的可达性分层**（`apps/*` 加 `python/sdk-runtime`）。这样得到的运行时层更紧凑，但会把 MCP 客户端与 OpenTelemetry 导出器判为仅开发用途——而运行已安装仓库的用户完全可以挂载它们。这会低估披露，对法务通告来说错在了更危险的一侧。
+
+**把披露文件做成双语对。** 其他根文档都是成对的，但这份文件是上游包名、SPDX 标识与网址构成的表格，可翻译的只有寥寥几段章节导语。`scripts/translation-pairing.ts` 的发现范围限定在 `README*`、`.agents/notes/**`、`docs/**` 与 `python/**`，根目录下的非 README 文件在构造上就不属于双语语料；双语入口由 README 对承担。
+
+## Consequences
+
+此后增删依赖都需要运行 `pnpm run gen-third-party-notices` 并提交结果，否则 `doc-sync` 失败。这正是预期成本——披露不可能再悄悄过期。
+
+生成器需要已安装的工作树，因此比纯源码生成器更重；发布元数据不可用的新包需要补一条 `OVERRIDES`，而不是默默渲染出空白许可证。这两类失败都会明确报错并指出补救方式。
+
+分层规则是编码在一个常量里的政策。若新增了不参与交付的工作区区域——第二层测试基础设施、另一个站点——就要同步扩展 `DEV_ONLY_AREAS`，否则其依赖会被当作运行时依赖披露出去。

 ## Runtime npm dependencies
 
-Direct dependencies that ship in at least one runtime surface (CLI/TUI, Web UI, SDK runtime, or the website at serve time).
+External packages that a workspace package resolves at runtime. `scripts/install.sh` installs this repository itself, so the tier covers every plugin a user can mount from `cordis.yml` — not only what the `dsh` CLI/TUI, the Web UI, and the Python SDK runtime load by default.

+DeepSeek Harness is licensed under [BSD 3-Clause](LICENSE). It depends on the third-party open-source software listed below. Each project remains under its own license; nothing in this file changes those terms.
+
+This file lists **direct** dependencies declared by the workspace, generated from the workspace manifests by \`scripts/gen-third-party-notices.ts\` and verified fresh by \`pnpm run verify-third-party-notices\` (part of \`doc-sync\`). The complete npm transitive closure, with exact pinned versions, is recorded in [\`pnpm-lock.yaml\`](pnpm-lock.yaml) (inspect it with \`pnpm licenses list\`); the Python closure is recorded in [\`python/sdk/uv.lock\`](python/sdk/uv.lock).
+
+## Vendored source (\`vendor/\`)
+
+The Cordis framework and its foundation libraries are source-vendored into this repository rather than consumed from npm.

+# Agent Note: Versioned TUI first-run welcome
+
+Status: implemented
+
+English | [中文](2026-07-30-versioned-tui-first-run-welcome.zh.md)
+
+## Problem
+
+The shipped `dsh` terminal starts directly in the editor and gives first-time internal testers no durable orientation about the product's maturity or feedback channel. The existing one-line `welcome` banner subtitle cannot carry the supplied four-paragraph notice without crowding the normal session header, and putting onboarding in the session log would create a user turn or model-visible context that is unrelated to the user's work.
+
+The notice also needs a recognizable DeepSeek composition without copying another product's startup art or maintaining a hand-drawn approximation that drifts from the official mark.
+
+## Decision
+
+The official `dsh` launcher owns one versioned acknowledgement marker under the resolved `DSH_HOME`. It checks the immutable marker before boot, then mounts an effect-owned consumer of `ctx.tui.openOverlay()` only after the real TUI service is available. Enter is the sole acknowledgement action: the plugin creates and synchronizes the fixed per-version marker before closing. Escape and every other non-navigation input leave the overlay open; disposal or process exit before Enter writes nothing. The version is part of the marker filename, so incrementing the centrally owned notice version presents materially revised copy once without migrating or rewriting an aggregate settings document.
+
+The marker is launcher state rather than session persistence because eligibility spans sessions and workspaces but is scoped to one Harness home. Exclusive file creation makes concurrent Enter actions idempotent without a read-modify-write race or dependency on the independently evolving settings stack. The notice never appends a session event, injects model context, or creates a user turn; resume therefore presents it only when the same Harness home has not acknowledged that version and never replays it from the session log.
+
+The supplied official `24x24` DeepSeek SVG is committed as the visual source. Static full, compact, and minimal terminal rasters sample that exact path at decreasing square resolutions; they do not redraw the contour. Unicode `▀`/`▄`/`█` cells preserve two vertical source pixels per terminal cell, while an explicitly ASCII-only locale uses the bit-equivalent `'`/`_`/`#` fallback. ANSI styling stays outside both the SVG and editable copy: `ctx.tui` supplies a semantic `brand` role, using the official `#4D6BFE` ink when truecolor is available, standard ANSI blue otherwise, and plain text when color is disabled. The normal startup banner retains its existing gradient.
+
+The overlay is centered and consumes the available terminal width. Wide terminals place the full icon beside the title and prose; medium and narrow terminals stack the compact or minimal icon above them; low height removes the icon before reducing prose space. The prose scrolls while the title and only action remain fixed. The quotation is promoted to its own visual paragraph without changing the centrally owned Chinese string. Closing through Enter returns modal ownership to the existing FIFO manager, which restores the editor and leaves the normal startup banner, transcript, and focus behavior intact.
+
+## Verification
+
+Focused unit coverage pins the supplied SVG and Chinese copy hashes, version bumps, exclusive concurrent acknowledgement, malformed markers, persistence retry, Escape behavior, ASCII fallback, width-tier selection, bounded rendering, and low-height scrolling. Real Loader/PTY cases cover 60, 80, 120, and 160 columns plus a low-height viewport, emit semantic terminal snapshots, prove first launch then second-launch suppression under one `DSH_HOME`, and prove a resumed session appends no notice-derived user message or turn; ordinary terminal-exit lifecycle events remain unchanged.
+
+## Alternatives considered
+
+**Reuse the TUI `welcome` subtitle.** It is one transient header line whose normal job is to identify an untitled session. The required prose and action would either be clipped or permanently crowd ordinary launches.
+
+**Copy Claude Code's startup art or composition.** Its strong hierarchy is useful product evidence, but its graphic, layout, and brand treatment belong to another product. The official DeepSeek SVG provides a direct brand source, and the terminal composition is derived independently around this notice's copy and responsive constraints.
+
+**Hand-draw an original whale.** A freehand silhouette can be recognizable yet still disagree with the official mark's body, internal negative space, fin, and tail. Exact-path raster sampling keeps the terminal limitation explicit and makes every tier traceable to one source asset.
+
+**Store a boolean in session events or a shared settings document.** Session state has the wrong lifetime and would pollute replay or model-visible history. An aggregate document would require cross-process read-modify-write locking for one immutable fact; a version-named exclusive marker has no lost-update shape.
+
+**Allow Escape or a later-reminder action.** Either would make dismissal indistinguishable from acknowledgement or introduce reminder policy that the notice does not need. Normal process exit remains the abort path and leaves the version unacknowledged.
+
+## Consequences
+
+Each Harness home receives the notice once per copy version, only after a successful Enter acknowledgement. Maintainers can edit all bilingual wording and the version in one small owner file, and can update the official SVG and derived static rasters in their separate visual owner without chasing snapshots for full prose copies.
+
+The terminal cannot display SVG vectors directly, so its faithful representation is resolution-bounded. Smaller tiers preserve the sampled silhouette but necessarily lose fine detail; low-height terminals prefer readable prose and an always-reachable action over brand art. The marker format is intentionally one-file-per-version during the pre-release period; old markers are harmless and no compatibility reader is required.

+# Agent Note: 版本化 TUI 首次运行欢迎页
+
+Status: implemented
+
+[English](2026-07-30-versioned-tui-first-run-welcome.md) | 中文
+
+## 问题
+
+已交付的 `dsh` 终端会直接进入编辑器，没有为首次使用的内部测试者提供持久的产品成熟度说明或反馈渠道指引。现有单行 `welcome` banner 副标题无法容纳指定的四段通知，否则会挤占正常的会话 header；如果把 onboarding 写入会话日志，还会创建一个与用户工作无关的用户轮次或模型可见上下文。
+
+该通知还需要形成具有辨识度的 DeepSeek 视觉构图，同时不能复制其他产品的启动图形，也不能维护一份会偏离官方标志的手绘近似图。
+
+## 决策
+
+官方 `dsh` 启动器在解析后的 `DSH_HOME` 下持有一个版本化确认标记。它会在启动前检查该不可变标记，并仅在真实 TUI 服务可用后，挂载一个由 effect 持有的 `ctx.tui.openOverlay()` 消费方。Enter 是唯一确认操作：插件先创建并同步固定的逐版本标记，再关闭浮层。Escape 和其他所有非导航输入都会让浮层保持打开；在按 Enter 前进行资源释放或退出进程不会写入任何内容。版本号属于标记文件名的一部分，因此只需递增集中持有的通知版本，即可让有实质修改的文案重新展示一次，无需迁移或改写聚合设置文档。
+
+该标记属于启动器状态，而非会话持久化，因为展示资格跨越会话与 workspace，但作用域仅限一个 Harness 主目录。独占文件创建使并发 Enter 操作保持幂等，无需承担读取、修改、写入竞态，也不依赖独立演进的设置栈。该通知绝不追加会话事件、注入模型上下文或创建用户轮次；因此，恢复会话只会在同一个 Harness 主目录尚未确认该版本时展示通知，也绝不会从会话日志中回放通知。
+
+指定的官方 `24x24` DeepSeek SVG 作为视觉真源提交。静态的完整、紧凑和最小终端栅格图以逐级降低的方形分辨率对该精确路径取样，不会重新绘制轮廓。Unicode `▀`/`▄`/`█` 单元格让每个终端单元格保留两个垂直方向的源像素；明确仅支持 ASCII 的 locale 则使用位级等价的 `'`/`_`/`#` 回退。ANSI 样式与 SVG 和可编辑文案完全分离：`ctx.tui` 提供语义化 `brand` 角色，在真彩色可用时使用官方 `#4D6BFE` 色值，否则使用标准 ANSI 蓝色；禁用颜色时则使用纯文本。普通启动 banner 保留现有渐变。
+
+浮层居中显示，并使用可用的终端宽度。宽终端将完整图标置于标题与正文旁边；中等和窄终端把紧凑或最小图标堆叠在正文上方；高度不足时，先移除图标，再减少正文空间。正文可以滚动，而标题和唯一操作保持固定。引用内容会提升为独立的视觉段落，但不会改变集中持有的中文字符串。通过 Enter 关闭浮层后，模态所有权会交还给现有 FIFO 管理器；该管理器恢复编辑器，同时保持正常的启动 banner、transcript（文本记录）和焦点行为不变。
+
+## 验证
+
+聚焦单元测试固定指定 SVG 与中文文案的 hash、版本递增、并发独占确认、格式错误的标记、持久化重试、Escape 行为、ASCII 回退、宽度分级选择、有界渲染和低高度滚动。真实 Loader/PTY 用例覆盖 60、80、120、160 列以及一个低高度 viewport，产出语义终端快照，证明同一个 `DSH_HOME` 下首次启动后再次启动会抑制展示，并证明恢复会话不会追加任何由通知衍生的用户消息或轮次；普通终端退出的生命周期事件保持不变。
+
+## 曾考虑的替代方案
+
+**复用 TUI 的 `welcome` 副标题。** 它是一行瞬态 header，正常职责是标识无标题会话。所需正文和操作要么会被裁剪，要么会永久挤占普通启动界面。
+
+**复制 Claude Code 的启动图形或构图。** 其清晰的视觉层级是有用的产品证据，但图形、布局和品牌处理属于另一个产品。官方 DeepSeek SVG 提供直接的品牌来源，而终端构图围绕本通知的文案与响应式约束独立推导。
+
+**手绘原创鲸鱼。** 自由绘制的轮廓可以具有辨识度，却仍可能与官方标志的身体、内部负空间、鳍和尾部不一致。对精确路径进行栅格取样，可以明确呈现终端限制，并让每个分级都能追溯到同一个源资产。
+
+**在会话事件或共享设置文档中存储布尔值。** 会话状态的生命周期不正确，还会污染回放或模型可见历史。聚合文档为记录一个不可变事实，需要承担跨进程读取、修改、写入锁；按版本命名并独占创建的标记不存在更新丢失问题。
+
+**允许 Escape 或稍后提醒操作。** 两者都会让取消与确认无法区分，或引入本通知并不需要的提醒策略。正常退出进程仍是中止路径，并会让该版本保持未确认状态。
+
+## 后果
+
+每个 Harness 主目录在每个文案版本中都会收到一次通知，且仅在用户成功按 Enter 确认后停止展示。维护者可以在一个小型 owner 文件中编辑所有双语文案和版本，也可以在独立的视觉 owner 中更新官方 SVG 与衍生静态栅格图，无需到各个快照中查找完整正文副本。
+
+终端无法直接显示 SVG 矢量图，因此其忠实呈现受分辨率限制。较小分级会保留取样后的轮廓，但必然损失精细细节；低高度终端优先保障正文可读和操作始终可达，而非展示品牌图形。在预发布阶段，标记格式有意采用每个版本一个文件；旧标记无害，也无需兼容性读取器。

 - treats the **invoking directory** as the workspace — sessions, relative paths, and workspace instructions resolve from the cwd (`dsh meta` is the sole exception, below);
 - tells the agent where its own source lives: after boot it adds a prompt section naming this harness checkout, resolved from the launcher's real path so it holds under a PATH symlink and an arbitrary cwd, so the self-referential `cordis` toolset can read and modify it;
 - applies the personal overlay from `~/.dsh` (see [app-boot's Personal config](../../packages/ui/app-boot/README.md#personal-config)): `.env` fills environment gaps (ambient > project `.env` > personal `.env`), `config.yaml` patches the booted tree.
+- presents the [versioned first-run welcome](../../.agents/notes/implemented/feature/2026-07-30-versioned-tui-first-run-welcome.md) through the mounted TUI overlay service when its immutable marker is absent under `DSH_HOME`; only Enter creates that version's marker, while Escape, disposal, or process exit leaves it eligible. The official DeepSeek icon, responsive terminal rasters, bilingual copy, and notice version are static local owners; the overlay never writes a session event or model context.
 
 `dsh meta` is that same TUI with this harness checkout as the workspace, so working on dsh itself needs no `cd`. It chdirs to the checkout root — resolved from the launcher's real path, the same root the source-path prompt section names — after both `.env` layers are loaded, so environment precedence is unchanged while the session cwd and HMR watch root move together. Meta always starts a fresh session and accepts no default-surface options; use ordinary `dsh --resume ` to resume a persisted session.

 This package owns interactive terminal presentation and input only. It injects `agents`, [`commands`](../commands/README.md), `llm`, `systemPrompt`, `tokenMeter`, `tools`, and `userInteraction`, optionally reads a `skills` service (present only when one is mounted), then drives an agent created or resumed by app or developer code. Agent lifecycle, persistence, and the model-facing [`ask_user_question`](../tool-ask-user/README.md) tool remain separate composition entries.
 
-After terminal startup succeeds, the package provides the terminal-local `ctx.tui` extension service. A plugin that injects it can call `openOverlay()` with a component factory and constrained layout options; the host exposes the viewport, semantic theme, display-text escaping, redraw, close, and a lifetime signal, but not the pi-tui tree, terminal, focus controller, or overlay handle. Plugin overlays, the model selector, and user questions share one FIFO modal queue. Each request is an effect of the calling plugin fiber, so unload removes queued work or closes visible work before cleanup settles; terminal shutdown unloads dependents before stopping pi-tui. Overlay state is not logged or replayed. Component code is trusted and may render ANSI styling, but must pass untrusted text through `host.display()`.

 The TUI rebuilds resumed history from the append-origin session events, renders Markdown responses and reasoning, applies each tool's `presentCall` / `presentResult` intent to terminal, diff, or generic cards, keeps the standing `todo/write` plan above the editor (cleared on the next `turn/start`), and presents `ctx.userInteraction` questions in a wide bottom-left keyboard panel with progress, numbered options, and aligned descriptions. The latest logged session title becomes the header subtitle, with `welcome` before a title exists, and the terminal window title becomes ` — `. A durable `llm/retry` event retracts the failed step's live chunks and renders the scheduled retry count, delay, and failure in the transcript; success, exhaustion, and cancellation then settle through ordinary session events. The footer totals each logged model step's usage once, including failed attempts, while treating committed-message usage as a fallback for logs without a usage chunk. Its idle view compares token-meter pressure with `ctx.llm.resolveModelInfo()` context for the current route, displays `context unknown` when the adapter has no capacity metadata, and also shows tool-card mode plus the current model and any explicitly selected reasoning effort; while the agent runs, an elapsed working indicator and `esc interrupt` replace that summary. A surface replacement never rewrites the rendered transcript: the conversation it shadows stays readable, and a landed compaction checkpoint adds one dim `… earlier context was compacted …` marker at its log position, so the terminal reports where the model stopped seeing that history instead of erasing it. Model-only replacement copies — a pruned tool result, a regenerated assistant message — render nothing.

Colors and attributes are separately typed, so `bold(accent(x))` compiles and `accent(error(x))` does not — SGR has no color stack, so nesting one color inside another silently drops the outer color at the inner one's close. Attributes occupy independent SGR groups and compose with any color in either order. Run `/palette` to see every role as your terminal renders it, with its SGR pair.

 Grouped regions (user prompts, assistant replies, tool cards) are separated by a bold, underlined role header in the role color and blank-line spacing rather than a filled block or a per-line prefix, so a mouse drag-select copies the message text without any leading bar or indent; a tool card's status (pending, error, success) shows in its colored, underlined title glyph and title. Inside a tool card, the whole body — presenter title, a terminal `$` command and cwd, and the tool's own output — renders in one dim tone, so only the status-colored header carries color and the body reads as one recessed block instead of a run of competing shades; an injected-context card's prose is the same tone as its header. A diff card's `+`/`-` lines and a `[signal …]` marker stay colored, because there the color is the meaning rather than emphasis. The question panel emphasizes its active row with bold accent text, while selectors use reverse video. These treatments are foreground-only, so they never collide with the terminal background. Set `color: false` to strip all styling.

Subject: [PATCH 098/557] test: cover the TUI search-card fallback and refresh
 the cordis-inspect golden

- Add a search result-view scenario to the TUI tool-card test so the
  card:'search' fallback branch (no view content -> raw result content) is
  covered; restores transcript.ts branch coverage to 100%.
- Refresh the cordis-inspect-jsdoc golden for the kind -> shape rename in the
  ToolResultView JSDoc that cordis_inspect echoes.

 error state
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The nested read of a missing file surfaces its error state as 失败 in the
code-dispatch row summary, a consequence of this PR's read-card error
presentation. The golden predated it (never re-recorded while the PR was
conflicting); refreshed keyless via DSH_SNAPSHOT=refresh over the existing
session.jsonl.

Subject: [PATCH 100/557] fix(web-search-card): surface truncation recovery,
 widen cardless fallback, validate wire shape, fix tail-cap
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Address the ds-review-bot findings on the search card:

- searchCardModel dropped the result view's `content`, so a capped search's
  `Full … stored at: ` recovery footer vanished from the UI (the card
  replaces the raw text). Thread it through as `SearchCardModel.recovery` and
  render it below the card at all three sites, only when truncated.
- SearchRow's fallback body was gated on `state === 'error'`, so a settled
  non-error call with no card (a successful nested run_code sub-dispatch, a
  legacy generic result) showed only its summary with content lost. Widen it to
  any settled call with `search === null`.
- searchCardModel trusted the `files`/`paths` shape the host wire schema only
  string-checks; a malformed known-kind frame would crash SearchBlock. Validate
  the full shape and fall to the generic path on mismatch.
- SearchBlock's restored tail file header added a row without consuming a tail
  slot, exceeding maxLines by one and overstating the hidden count. Make it
  consume a slot so the visible count holds at maxLines and `hidden` stays exact.

Correct the fixture JSDoc (now genuinely exceeds the row cap) and the Agent Note
recovery-text claim, sync the ui-conversation bilingual README with the search
row, and add an assembled keyless snapshot (apps/web/tests/search-card.snapshot.ts)
that pins the grep card's shape from the built bundles.

 ## Decision
 
-`SearchBlock` is a `ui-primitives` component that renders a completed search as either shape, and the Web render sites for a `grep`/`glob` call consume the search render intent through it. `ui-conversation/src/client/contract/search-card-model.ts` is the single place that turns the snapshot's `resultView` into the component's props, so no render site re-derives the shape. It returns null — the generic path — whenever the result view is not a search card, including a still-running call (a search card is result-time only, so there is nothing before `execute`), a generic result a `grep`/`glob` failure or a nested `run_code` dispatch produces, a terminal result view, and a `card` value this client version does not know.

 The asymmetry with the terminal card is deliberate and inherited from the backend contract: `terminalCardModel` reads both `callView` and `resultView` because a command, cwd, and description exist at call time; `searchCardModel` reads only `resultView` because a search's matches or paths exist only after execution. A running search row therefore shows its summary alone, with no card.

 - **Flat path list.** The paths shape renders one path per row, no headers.
-- **A capped indicator.** When `truncated`, the banner summary folds the pre-cap total in — `显示 X / 共 N 处匹配 · K 个文件` for grep, `显示 X / 共 N 个路径` for glob — so the card never presents a capped page as the complete result; a reader who wants the rest follows the spill locator in the model-facing text, exactly as the model does.

+- **A recovery footer for a capped result.** The card holds only the retained page, but the locator to the rest — grep/glob's `Full … stored at: ` footer — lives only in the result view's `content` text, not in the structured matches/paths. Because every render site replaces the raw result with the card, `searchCardModel` surfaces that flattened `content` as `SearchCardModel.recovery` when (and only when) the result was capped, and each render site draws it below the card. Without this the one path to the dropped rows would vanish from the UI; an uncapped result carries every row, so its `content` adds nothing and is dropped.
 - **No soft wrapping.** Result rows are `white-space: pre` inside a horizontally scrolling box, so a long match line or a deep path scrolls sideways rather than folding.
 - **Height cap with an expand control.** More than `DEFAULT_SEARCH_MAX_LINES` (16) rows shows a head/tail slice with a button reporting the hidden count, the same shape and arithmetic as `TerminalBlock`.
 - **Copy.** The copy control writes the whole structured result — every file and match, or every path — regardless of the height cap or which groups are collapsed, so the clipboard carries the result rather than what the card happens to be showing.

Both tool names get the same row because the derived `kind` decides the shape, so a second component would duplicate it. (This resident posture matches the current terminal/diff cards; a separate later PR unifies the whole-row collapse/expand interaction and flips all resident cards at once — out of scope here.)

Both tool names get the same row because the derived `kind` decides the shape, so a second component would duplicate it. A capped result's recovery footer sits below the card. Because the keyed row owns this render slot, a settled call with no search card — an errored search (grep/glob emit no result view on error), a successful nested `run_code` sub-dispatch (the backend computes no `presentationMeta`, so `resultView` is null), or a legacy generic result — would otherwise show only its summary with its content lost; the row surfaces that model-facing text as a fallback body, keyed on `search === null && settled` rather than on the error state alone. (This resident posture matches the current terminal/diff cards; a separate later PR unifies the whole-row collapse/expand interaction and flips all resident cards at once — out of scope here.)
+- **The generic fallback** (`chat/GenericToolCard` → `chat/ToolRow`) threads the derived model as an expand-gated body, the same arm `terminal` uses: a `grep`/`glob` result with no keyed row (none in the shipped app, since both are registered) still renders its card, with the recovery footer, behind the row's expand toggle.
+- **The details panel** (`skeleton/DetailsPanel`) renders the card at the primitive's own full height in the Output section, with the recovery footer below it, keeping the JSON Input section.
 
 `CHAT_SEARCH_MAX_LINES` (8) is the row cap, half the primitive's default the panel keeps, for the same reason as `CHAT_TERMINAL_MAX_LINES`: the chat flow is a summary surface read across many calls, the panel is the single-call reading surface.

 A tool call declaring the `terminal` render intent renders its command output inline, at both conversation render sites, through ui-primitives' `TerminalBlock`. `contract/terminal-card-model.ts` is the single derivation from the snapshot's `callView`/`resultView` pair, so the sites cannot disagree about a command, its cwd, or its exit status; it yields null — the generic path — for any other card tag, including one this client version does not know. Both sites therefore also show the card's run-state dot, which is the same `StateDot` semantic a tool row's leading icon carries, so a row and its own card always agree about one command's state. A multi-line command gets one prompt row per line, with the dot marking the call once on the first row — the exit status is the whole call's, so a dot per line would claim a per-line outcome bash does not report. The keyed `BashRow` carries the card resident below its summary row; since tool rows are no longer details-panel click targets, the card's copy and expand controls are the row's only interactions. The render-site fallback row keeps the card behind its existing expand control. Rows cap at `CHAT_TERMINAL_MAX_LINES` (8) against the panel's 16, which is what keeps a summary surface bounded — the panel stays the single-call reading surface. Inline output is licensed for this intent alone; a generic tool's content remains panel-only ([decision](../../../.agents/notes/implemented/feature/2026-07-28-web-terminal-card.md)).
 
+A `grep`/`glob` call declaring the `search` render intent renders its result inline, at the same render sites, through ui-primitives' `SearchBlock` — grep's matches grouped by file (each a collapsible header of `lineNumber: line` rows), glob's flat path list. `contract/search-card-model.ts` is the single derivation from the snapshot's `resultView`; unlike the terminal card it reads no `callView`, since a search has no matches or paths before `execute`, so a running search shows its summary alone. It yields null — the generic path — for any non-search result view, a `card` or `kind` this client version does not compile, and (because those ride the untrusted wire frame) a known kind whose `files`/`paths` is malformed. The keyed `SearchRow`, registered under both `grep` and `glob` since the derived `kind` decides the shape, carries the card resident below its summary; the render-site fallback keeps it behind the expand control. Both cap at `CHAT_SEARCH_MAX_LINES` (8) against the panel's 16. A capped search drops rows from the card, but the locator to the rest — grep/glob's `Full … stored at …` footer — lives only in the result text, so the derivation surfaces that as a recovery footer below the card when (and only when) the result was truncated; a settled call with no card at all (an errored search, a nested `run_code` sub-dispatch, a legacy generic result) falls back to its flattened result text so nothing is lost behind a bare summary ([decision](../../../.agents/notes/implemented/feature/2026-07-30-web-search-card.md)).
+
 Tool rows are slots too — the standalone tool ring (`ToolViewRegistry`/`ctx.toolviews`/outlet) is retired. The chat entry declares the keyed `'conversation.chat.toolview'` hole (session scope; the key space is runtime-open); its render site dispatches per row via `entryKey: toolName` with `GenericToolCard` as the call-site `fallback`. The owner payload is the uniform `ToolRowOwnerProps` (`callId`/`toolName`/`block`/`openFile`) and `ToolRowProps` pre-composes it with the session standard kit. A registrant is a plain plugin: `ctx.slots.register({ name: 'conversation.chat.toolview', key: '', inject? }, Row)` with `inject: ['slots', 'conversation']` as the load-order seam (apply mounts ConversationService after the chat registration, so the service being present guarantees the slot is declared); session differentiation happens inside the component (`useSessions` reading `parentId` — the bash sample is the third-party-posture exemplar). Trajectory/waterfall toolview slots share this shape and land with their own render sites (RendersCheck rejects a declaration nobody renders).
 
 The todo surfaces are two registrations over that shape, both plain registrant plugins with `inject: ['slots', 'conversation']`. `TodoRow` takes the `'conversation.chat.toolview'` key `todo_write` and summarizes what the call attempted (`/ 已完成 · ` parsed from its args, falling back to the generic summary on malformed or wrongly-shaped model JSON, and keeping the generic dot for non-ok execution states so a cancelled call never reads as a completed update). `TodoDock` takes the `'conversation.input.dock'` list slot at `order: 10` — between Goal and Queue — and is the plan strip: it reads the host-computed `todos` projection via `useProjection` (standing plan: latest `todo/write` with no later `turn/start`) and renders `TodoPanel`, which takes the plain list, hides itself while the list is empty, and starts collapsed as a header of title plus `"/ tasks ·  in progress"` (status glyphs are the figma check / progress / dashed-pending set). The dock adapter owns the selection so the panel stays a pure function of its props; the standing list lives here rather than in the row so the row stays one line. Anything the input-zone composer chain hides (a `conversation.composer` takeover such as ui-question's) hides the whole dock, this strip included.

 声明 `terminal` 渲染意图的工具调用，会在两个对话渲染点上都通过 ui-primitives 的 `TerminalBlock` 内联渲染其命令输出。`contract/terminal-card-model.ts` 是从快照的 `callView`／`resultView` 对推导的唯一位置，因此两个渲染点不可能在命令、cwd 或退出状态上产生分歧；对任何其他 card 标签——包括当前客户端版本不认识的标签——它返回 null，落回通用路径。因此两个渲染点也都显示卡片的运行状态点，它与工具行行首图标承载同一套 `StateDot` 语义，所以一行与其自身的卡片对同一条命令的状态总是一致。多行命令的每一行各占一个提示行，状态点只在第一行为整次调用标记一次——退出状态属于整次调用，因此每行一枚就会声称一个 bash 并不报告的逐行结果。键控的 `BashRow` 把卡片常驻在摘要行下方；由于工具行已不再是详情面板的点击目标，卡片的复制与展开控件就是该行唯一的交互。渲染点兜底行则保持其既有的展开控件。行的上限是 `CHAT_TERMINAL_MAX_LINES`（8），面板为 16，正是这一点让摘要面保持有界——面板仍是单次调用的阅读面。内联输出只对该意图开放；通用工具的内容仍然只在面板中呈现（[决策](../../../.agents/notes/implemented/feature/2026-07-28-web-terminal-card.md)）。
 
+声明 `search` 渲染意图的 `grep`／`glob` 调用，会在同样的渲染点上通过 ui-primitives 的 `SearchBlock` 内联渲染其结果——grep 的匹配按文件分组（每个是一个可折叠的头，下辖 `lineNumber: line` 行），glob 是扁平路径列表。`contract/search-card-model.ts` 是从快照的 `resultView` 推导的唯一位置；与终端卡片不同，它不读 `callView`，因为搜索在 `execute` 前没有匹配或路径，所以运行中的搜索只显示摘要。对任何非搜索的结果视图、当前客户端版本无法编译的 `card` 或 `kind`、以及（因为这些都与不可信的 wire 帧同行）一个 `files`／`paths` 格式错误的已知 kind，它都返回 null，落回通用路径。键控的 `SearchRow` 因推导出的 `kind` 决定形态而同时注册在 `grep` 与 `glob` 下，把卡片常驻在摘要行下方；渲染点兜底行则把它保持在展开控件之后。两者上限都是 `CHAT_SEARCH_MAX_LINES`（8），面板为 16。被截断的搜索会从卡片里丢掉一些行，但通往其余部分的定位符——grep/glob 的 `Full … stored at …` 脚注——只存在于结果文本里，因此推导在（且仅在）结果被截断时把它作为恢复脚注画在卡片下方；一个完全没有卡片的已结算调用（出错的搜索、嵌套 `run_code` 子派发、旧日志的 generic 结果）则回退到其压平后的结果文本，从而不让任何内容丢失在一个光秃秃的摘要之后（[决策](../../../.agents/notes/implemented/feature/2026-07-30-web-search-card.md)）。
+
 工具行同样是 slot：独立工具环（`ToolViewRegistry`／`ctx.toolviews`／outlet）已经退役。聊天配置项声明键控的 `'conversation.chat.toolview'` 空位（Session scope；key 空间在运行时开放）；其渲染点逐行通过 `entryKey: toolName` 分发，并以 `GenericToolCard` 作为调用点 `fallback`。owner 载荷是统一的 `ToolRowOwnerProps`（`callId`／`toolName`／`block`／`openFile`），`ToolRowProps` 则预先将其与 Session 标准工具包组合。注册方只是普通插件：`ctx.slots.register({ name: 'conversation.chat.toolview', key: '', inject? }, Row)`，以 `inject: ['slots', 'conversation']` 作为加载顺序 seam（apply 在聊天注册后挂载 ConversationService，因此服务存在即可保证 slot 已声明）；Session 区分在组件内部完成（`useSessions` 读取 `parentId`，bash 示例是第三方姿态的范例）。Trajectory/waterfall 工具视图 slot 共享此形状，并随各自的渲染点落地（RendersCheck 会拒绝没有任何渲染方的声明）。
 
 审批经由本包声明的链接管编辑器：`ApprovalPanel` 注册为按选择器路由的 `'conversation.composer'` 配置项（ui-question 模式），在审批等待未决期间取代 InputBar 占据编辑器（琥珀色条、理由标题、来自运行中调用参数的配对命令行、一次性的拒绝／允许）。`contract/slots.ts` 中的 `PendingApproval` 领域面在运行时 `PendingWait` 载体之上拥有 wire 编码——带审计关联的 `ApprovalResponsePayload` 值；广播的 `approval/resolved` 帧使等待落定并恢复编辑器。侧边栏通过 manager 跟踪的 `waitingApproval` 列表位（未实例化会话同样点亮）镜像该阻塞状态，其优先级高于运行中圆环，直至问题解决。未决等待完全离开消息流：问题（ui-question）与审批（ApprovalPanel）都经编辑器接管作答，不再保留只读占位卡。编辑器底行的 Access 席位挂载 `PermissionSelect`，由 host 计算的 `permissions` 投影经标准工具包 `useProjection` 供数（key 缺席即隐藏 chip）；chip 打开 Menu 原语下拉，kebab-case 预设名渲染为 Title Case 标签（与 `/permission` popup 的显示变换孪生），选中会经由输入栏注入的 `command` 回调提交 `/permission ` 命令行。

Subject: [PATCH 101/557] fix(web-read-card): carry the base's required read
 offset in fixtures and specs

The base's ReadResultView now requires `offset` (persisted so an empty window
still knows its start). The connection fixture's read sample and read-card.spec's
resultRead helper supply it (the window's first line, 41).

Subject: [PATCH 102/557] fix(web-search-card): follow base rename kind->shape
 and view-drops-content
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The base (feat/search-presenter) renamed the search result view's discriminant
from `kind` to `shape` and removed the view's `content` field (a UI without a
card now falls back to the raw tool/result content). Adapt the web consumer:

- searchCardModel switches on `result.shape`; SearchBlock's own `kind` prop is
  mapped from it.
- The truncation recovery footer reads the block's raw `content` (where the
  `Full … stored at …` locator now lives) instead of the removed view content.
- Fixture grep/glob views use `shape` and drop `content`; the recovery footer
  rides the raw tool/result text.
- Tests and the bilingual Agent Note follow the rename and the recovery source.

 ## Problem
 
-The `grep` and `glob` tools declare a result-time `card: 'search'` render intent ([search render card](2026-07-30-search-render-card.md)): a `SearchMatchesResultView` (`kind: 'matches'`) carrying grep's matches grouped by file, or a `SearchPathsResultView` (`kind: 'paths'`) carrying glob's flat path list, both with a `truncated`/`total` capping signal. That view already reaches the browser — host, connection, and runtime deliver it onto `ConversationSnapshot` as `resultView` — but the Web client ignored it: every non-terminal, non-diff tool result fell through to the generic card, which renders the model-facing text. A web frontend that wants an expandable per-file group of matches, or a scannable path list, had only the pre-formatted text.

 This is the follow-up the search render card note names: that PR was the backend contract and its two producers; this PR is the web consumer.
 
 ## Decision
 
-`SearchBlock` is a `ui-primitives` component that renders a completed search as either shape, and the Web render sites for a `grep`/`glob` call consume the search render intent through it. `ui-conversation/src/client/contract/search-card-model.ts` is the single place that turns the snapshot's `resultView` into the component's props, so no render site re-derives the shape. It returns null — the generic path — whenever the result view is not a search card, including a still-running call (a search card is result-time only, so there is nothing before `execute`), a generic result a `grep`/`glob` failure or a nested `run_code` dispatch produces, a terminal result view, a `card` value this client version does not know, a `card: 'search'` view whose `kind` this version does not compile, and — because `kind` and the grouped/flat shape ride the same untrusted wire frame the host schema only string-checks — a known `kind` whose `files`/`paths` is missing or malformed (which would otherwise crash `SearchBlock` at `.reduce`/`.map`).

The result-view discriminant is `shape` (not `kind`, which the backend reserves for the call view's icon-picking tag); `SearchBlock`'s own prop stays `kind`, mapped from `shape` in this derivation.
 
 The asymmetry with the terminal card is deliberate and inherited from the backend contract: `terminalCardModel` reads both `callView` and `resultView` because a command, cwd, and description exist at call time; `searchCardModel` reads only `resultView` because a search's matches or paths exist only after execution. A running search row therefore shows its summary alone, with no card.
 
@@ -23,7 +23,7 @@ The component's contract:
 - **Grouped matches, collapsible per file.** Each file is a header row (a bold path plus its match count, the whole row the collapse control) followed by its `lineNumber: line` rows. Collapsing a group drops its match rows from the flattened list and from the height cap's arithmetic, but never from the copy text.
 - **Flat path list.** The paths shape renders one path per row, no headers.
 - **A capped indicator.** When `truncated`, the banner summary folds the pre-cap total in — `显示 X / 共 N 处匹配 · K 个文件` for grep, `显示 X / 共 N 个路径` for glob — so the card never presents a capped page as the complete result. When not `truncated` the summary is a plain structural count (`{n} 处匹配 · {m} 个文件`, or `{n} 个路径`).
-- **A recovery footer for a capped result.** The card holds only the retained page, but the locator to the rest — grep/glob's `Full … stored at: ` footer — lives only in the result view's `content` text, not in the structured matches/paths. Because every render site replaces the raw result with the card, `searchCardModel` surfaces that flattened `content` as `SearchCardModel.recovery` when (and only when) the result was capped, and each render site draws it below the card. Without this the one path to the dropped rows would vanish from the UI; an uncapped result carries every row, so its `content` adds nothing and is dropped.

 - **Height cap with an expand control.** More than `DEFAULT_SEARCH_MAX_LINES` (16) rows shows a head/tail slice with a button reporting the hidden count, the same shape and arithmetic as `TerminalBlock`.
 - **Copy.** The copy control writes the whole structured result — every file and match, or every path — regardless of the height cap or which groups are collapsed, so the clipboard carries the result rather than what the card happens to be showing.

 ## Problem
 
-`grep` 与 `glob` 工具声明了一个仅在结果阶段存在的 `card: 'search'` render intent（[search render card](2026-07-30-search-render-card.md)）：`SearchMatchesResultView`（`kind: 'matches'`）携带 grep 按文件分组的匹配，或 `SearchPathsResultView`（`kind: 'paths'`）携带 glob 的扁平路径列表，两者都带 `truncated`/`total` 截断信号。该视图已经到达浏览器 —— host、connection、runtime 把它作为 `resultView` 投递到 `ConversationSnapshot` 上 —— 但 Web 客户端忽略了它：每个非终端、非 diff 的工具结果都落到 generic 卡片，渲染面向模型的文本。想把搜索结果渲染成可展开的按文件匹配分组、或可扫读的路径列表的 web 前端，只有那段预格式化文本。

 这正是 search render card note 指名的后续：那个 PR 是后端契约和它的两个生产者，本 PR 是 web 消费者。
 
 ## Decision
 
-`SearchBlock` 是一个 `ui-primitives` 组件，把一次已完成的搜索渲染成两种形态之一，`grep`/`glob` 调用的 Web 渲染点都通过它消费搜索 render intent。`ui-conversation/src/client/contract/search-card-model.ts` 是把 snapshot 的 `resultView` 转成组件 props 的唯一位置，因此没有渲染点重新推导形态。当结果视图不是搜索卡片时它返回 null（走 generic 路径），包括仍在运行的调用（搜索卡片仅在结果阶段存在，`execute` 前无内容）、`grep`/`glob` 失败或嵌套 `run_code` dispatch 产生的 generic 结果、terminal 结果视图、本客户端版本不认识的 `card` 值、`kind` 是本版本无法编译的 `card: 'search'` 视图，以及 —— 因为 `kind` 和分组/扁平形态与 host schema 只做字符串校验的那同一个不可信 wire 帧同行 —— 一个 `kind` 已知但 `files`/`paths` 缺失或格式错误的视图（否则会让 `SearchBlock` 在 `.reduce`/`.map` 处崩溃）。

 与终端卡片的不对称是刻意的，继承自后端契约：`terminalCardModel` 同时读 `callView` 和 `resultView`，因为命令、cwd、description 在调用时就存在；`searchCardModel` 只读 `resultView`，因为搜索的匹配或路径只在执行后存在。因此运行中的搜索行只显示摘要，没有卡片。

the committed bytes inside the generator spec the test lane already runs.
Drops the separate doc-sync gate: no extra CI process, and a dependency
edit no longer bounces back from CI to rerun a generator.

 Open-sourcing this repository requires disclosing the third-party software it depends on, with each project's license. The disclosure has to be complete, has to stay true as dependencies change, and has to say something a reader can act on — which of these packages end up on a user's machine, and which only build and test the repository.
 
-A hand-written inventory answers none of those durably. Roughly a hundred rows of names and license strings derived from manifests drift silently the moment a package is added, removed, or relicensed, and nothing in `doc-sync` would notice.

 ## Decision
 
-[`THIRD_PARTY_NOTICES.md`](../../../../THIRD_PARTY_NOTICES.md) is generated by [`scripts/gen-third-party-notices.ts`](../../../../scripts/gen-third-party-notices.ts) from the workspace manifests, `vendor/README.md`, the `pyproject.toml` files, and `pnpm-workspace.yaml`. `pnpm run verify-third-party-notices` runs the generator with `--check` as a `doc-sync` leaf gate, so a dependency change that skips regeneration fails the same way a stale catalog does. The root README pair links the file from its License section.

The root README pair links the file from its License section.
+
+**Freshness is maintained, not merely enforced.** A pre-commit job regenerates the file and stages it whenever a manifest, lock file, `vendor/README.md`, or `pyproject.toml` is staged, so an unrelated dependency edit never has to come back and rerun a generator. The committed bytes are then asserted inside [`scripts/gen-third-party-notices.spec.ts`](../../../../scripts/gen-third-party-notices.spec.ts), which the test lane already runs — the check adds no gate process, no scheduler slot, and no separate CI step. `pnpm run verify-third-party-notices` remains available for a standalone check.
 
 The file discloses **direct** dependencies only. The complete npm closure with pinned versions already lives in `pnpm-lock.yaml` (`pnpm licenses list` renders it) and the Python closure in `python/sdk/uv.lock`; re-materializing either as prose would be a second, worse copy.

+The same spec that asserts freshness pins the tiering rule against fixture manifests — including the two cases that motivate it, a `dependencies` entry of a test-support package and a plugin package no app mounts — and pins that the vendored-table parser reads the committed manifest and yields nothing when the table shape changes, which is what makes the generator fail loud rather than emit an empty section.
 
 ## Alternatives considered
 
 **Keep the hand-written file and review it at release time.** Reviewing a hundred derived rows by eye is exactly the work a generator does correctly, and the file's own claim — that it lists every direct dependency — would be unverified between releases.
 
+**Verify through a dedicated `doc-sync` gate.** That is how every other generated artifact here is checked, and it was the first shape of this change. It costs a gate process and a scheduler slot in a matrix that is already long, and — worse — its only failure mode is telling a contributor, minutes after they pushed an unrelated dependency bump, to go rerun a generator. Regenerating at commit time removes the interruption, and the assertion inside a spec the test lane already runs keeps the guarantee at no additional CI cost.
+
 **Enumerate the full transitive closure.** The closure is thousands of packages, already recorded in the lock files with exact versions, and would bury the direct dependencies that a reader actually evaluates. The file points at the lock files and the `pnpm licenses list` renderer instead.

 ## Consequences
 
-Adding or removing a dependency now requires running `pnpm run gen-third-party-notices` and committing the result; `doc-sync` fails otherwise. That is the intended cost — the disclosure cannot silently go stale.
+A dependency edit now carries a regenerated notices file into the same commit. Contributors pay one generator run — about a second — on commits that touch a manifest, and nothing on any other commit. Committing with hooks disabled defers the cost to a test-lane failure that names the command.
 
 The generator needs an installed tree, which makes it heavier than a pure-source generator, and a new package with unusable published metadata needs an `OVERRIDES` entry rather than silently rendering a blank license. Both failures are loud and name the remedy.

Subject: [PATCH 105/557] refactor(ui-primitives): extract shared head/tail cap
 and copy-feedback helpers

The tail-header cap fix pushed SearchBlock's head/tail slicing arithmetic and
its copy-feedback hook over the duplication gate's threshold against the
byte-identical logic in TerminalBlock. Extract both into head-tail-cap.ts
(headTailCap) and use-copy-feedback.ts (useCopyFeedback) and consume them from
both blocks, deleting the clone rather than nudging it under the limit.

 The supplied official `24x24` DeepSeek SVG is committed as the visual source. Static full, compact, and minimal terminal rasters sample that exact path at decreasing square resolutions; they do not redraw the contour. Unicode `▀`/`▄`/`█` cells preserve two vertical source pixels per terminal cell, while an explicitly ASCII-only locale uses the bit-equivalent `'`/`_`/`#` fallback. ANSI styling stays outside both the SVG and editable copy: `ctx.tui` supplies a semantic `brand` role, using the official `#4D6BFE` ink when truecolor is available, standard ANSI blue otherwise, and plain text when color is disabled. The normal startup banner retains its existing gradient.
 
-The overlay is centered and consumes the available terminal width. Wide terminals place the full icon beside the title and prose; medium and narrow terminals stack the compact or minimal icon above them; low height removes the icon before reducing prose space. The prose scrolls while the title and only action remain fixed. The quotation is promoted to its own visual paragraph without changing the centrally owned Chinese string. Closing through Enter returns modal ownership to the existing FIFO manager, which restores the editor and leaves the normal startup banner, transcript, and focus behavior intact.

 指定的官方 `24x24` DeepSeek SVG 作为视觉真源提交。静态的完整、紧凑和最小终端栅格图以逐级降低的方形分辨率对该精确路径取样，不会重新绘制轮廓。Unicode `▀`/`▄`/`█` 单元格让每个终端单元格保留两个垂直方向的源像素；明确仅支持 ASCII 的 locale 则使用位级等价的 `'`/`_`/`#` 回退。ANSI 样式与 SVG 和可编辑文案完全分离：`ctx.tui` 提供语义化 `brand` 角色，在真彩色可用时使用官方 `#4D6BFE` 色值，否则使用标准 ANSI 蓝色；禁用颜色时则使用纯文本。普通启动 banner 保留现有渐变。

 The official `dsh` launcher owns one versioned acknowledgement marker under the resolved `DSH_HOME`. It checks the immutable marker before boot, then mounts an effect-owned consumer of `ctx.tui.openOverlay()` only after the real TUI service is available. Enter is the sole acknowledgement action: the plugin creates and synchronizes the fixed per-version marker before closing. Escape and every other non-navigation input leave the overlay open; disposal or process exit before Enter writes nothing. The version is part of the marker filename, so incrementing the centrally owned notice version presents materially revised copy once without migrating or rewriting an aggregate settings document.
 
-The marker is launcher state rather than session persistence because eligibility spans sessions and workspaces but is scoped to one Harness home. Exclusive file creation makes concurrent Enter actions idempotent without a read-modify-write race or dependency on the independently evolving settings stack. The notice never appends a session event, injects model context, or creates a user turn; resume therefore presents it only when the same Harness home has not acknowledged that version and never replays it from the session log.
+The marker is launcher state rather than session persistence because eligibility spans sessions and workspaces but is scoped to one Harness home. Each Enter syncs a random same-directory file before atomically replacing the fixed marker; concurrent launches publish the same immutable fact, so same-value last-writer-wins replacement has no lost-update shape and needs no lock or dependency on the settings stack.

 The supplied official `24x24` DeepSeek SVG is committed as the visual source. Static full, compact, and minimal terminal rasters sample that exact path at decreasing square resolutions; they do not redraw the contour. Unicode `▀`/`▄`/`█` cells preserve two vertical source pixels per terminal cell, while an explicitly ASCII-only locale uses the bit-equivalent `'`/`_`/`#` fallback. ANSI styling stays outside both the SVG and editable copy: `ctx.tui` supplies a semantic `brand` role, using the official `#4D6BFE` ink when truecolor is available, standard ANSI blue otherwise, and plain text when color is disabled. The normal startup banner retains its existing gradient.

Subject: [PATCH 118/557] docs: fix notices template claim and close generator
 omission paths

The template still described the removed doc-sync gate; it now states the
pre-commit + test-lane mechanism that actually runs. Read the nested
native/landlock-run/packages manifests, accept PEP 508 requirements with
no version or with a marker, and reject a vendor/README.md table that
stops covering a vendored directory instead of dropping it silently.
Extend the pre-commit glob to the generator and the build-time pin
source; record the deletion trigger gap the test lane backstops.

+**Freshness is maintained, not merely enforced.** A pre-commit job regenerates the file and stages it whenever a generator input is staged — any manifest, either lock file, `vendor/README.md`, a `pyproject.toml`, the generator itself, or the script holding the build-time pin — so an unrelated dependency edit never has to come back and rerun a generator.

+One trigger gap is accepted rather than worked around: lefthook inspects only files present on disk, so **deleting** a manifest runs no job, and removing a package reaches the assertion in the test lane instead. Reconstructing the staged file list to include deletions was tried and does not work — lefthook filters the list against the working tree either way. The assertion is the backstop for exactly this case.
 
 The file discloses **direct** dependencies only. The complete npm closure with pinned versions already lives in `pnpm-lock.yaml` (`pnpm licenses list` renders it) and the Python closure in `python/sdk/uv.lock`; re-materializing either as prose would be a second, worse copy.

 **Concurrent views converge without stale replacement.** The acknowledgement write omits `expectedRevision` deliberately: every tab writes the same version to one path, so the operation is idempotent and preserves sibling fields instead of rebuilding the section. `settings/document-updated` becomes `host/settings-changed`; an already mounted tab refetches and advances when another tab or an external editor commits the current version. The API proxy exposes this one product namespace through a closed allowlist beside configurable-provider namespaces, without treating its changes as model-catalog invalidations.
 
-**The welcome modal is scan-first and has one completion path.** Its hierarchy is a declaration title, one status sentence, one emphasized feedback callout, one consequence sentence, and a restrained quotation; the notice version changes whenever that authored copy changes materially. It renders no close icon or secondary action, installs no Escape handler, and assigns no click handler to the mask. Its mask starts below the 80 px top chrome and preserves `position:absolute`, zero left/right/bottom offsets, `rgba(0, 0, 0, 0.24)`, and `backdrop-filter: blur(2px)`. Continue is the sole button and receives initial focus.
+**Onboarding temporarily owns the viewport as one continuous stage.** A solid product surface replaces the complete application view through a body-level portal and marks the underlying app root inert; the exact required mask remains mounted behind that surface with `position:absolute`, zero left/right/bottom offsets, `top:80px`, `rgba(0, 0, 0, 0.24)`, and `backdrop-filter: blur(2px)`. Welcome and conditional credential setup render as successive pages in this stage instead of independent modals. Both pages reuse the Web UI's black `BrandWordmark`. The welcome page preserves the four authored paragraphs verbatim under the `内测声明` title; every paragraph uses one 16/28 body scale, and only the requested action clause inside the final paragraph receives a subtle 500 weight. A short staggered opacity/vertical entrance supplies pacing without blocking interaction and disappears under reduced motion. The title receives initial focus, Continue is the sole button, and no close, Escape, or mask-click path exists.

 **并发视图无需陈旧的整体替换即可收敛。** 确认写入有意省略 `expectedRevision`：每个标签页都向同一路径写入相同版本，因此该操作是幂等的，并会保留同级字段，而不是重建整个分节。`settings/document-updated` 会转为 `host/settings-changed`；另一个标签页或外部编辑器提交当前版本后，已挂载的标签页会重新拉取状态并推进。API 网关在可配置提供方 namespace 之外，通过封闭的允许列表暴露这一个产品 namespace，同时不会把它的变更视为模型目录失效事件。

 Settings ownerless-copy and product-onboarding plugin: registers everything on the Settings surface that belongs to no single feature — the shell's trigger/header/close chrome content, the General section (Permission/Tool Call skeleton rows + the `settings.general.item` slot declaration), the `settings` dictionaries, and the first ordered welcome step. Feature-owned rows (Language, Appearance), sections (Models), and conditional onboarding steps stay with their feature packages.

The Host half registers `ui-onboarding` in the user-settings seam; the browser compares `welcomeNoticeVersion` for exact equality and writes the current value only after Continue succeeds. The path mutation is idempotent across tabs and preserves sibling settings, while `host/settings-changed` makes an externally acknowledged notice advance without a reload.

Subject: [PATCH 198/557] fix(locale): gate browser detection on window and
 tolerate a missing languages list
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Node >= 21 exposes a global `navigator` reporting the machine's own language,
so gating detection on `navigator` let a non-browser boot of the client tree
resolve to `en` instead of the documented fallback; `window` is the browser
test. `navigator.languages` is spec-required but absent on some embedders and
older WebViews, where spreading it would throw at boot, so the walk tolerates
its absence and `navigator.language` covers that host.

The per-spec pin boilerplate collapses into one suite-level
`usePinnedBrowserLanguages('zh-CN')`, which owns the rationale in
dsh-client-test-runtime, and the English-browser e2e scenario now clears the
console warnings channel too — its page has no closing inventory spec.

 - A first visit from an English browser lands in English, and the Language row still shows the same two self-described options, so the escape hatch is unchanged in either direction.
 - `FALLBACK_LOCALE` narrows to its real job — the dictionary fallback and the no-signal answer — and stops standing in for "the user has not chosen".

+- Tests that construct a `LocaleService` under jsdom now depend on the environment's `navigator`: specs asserting localized copy declare their browser with one suite-level `usePinnedBrowserLanguages('zh-CN')` (dsh-client-test-runtime), and any future spec asserting a default must do the same. This package's own specs stub the globals directly, because they need shapes the helper deliberately cannot express (absent `languages`, a list decoupled from `language`, no `window` at all).

Subject: [PATCH 200/557] test(web): refresh seeded-history/message-actions
 goldens for keyed read row
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The read tool now renders through the keyed ReadRow (Read · {path} chrome with a
resident read card) instead of the generic disclosure row, so the seeded read
turns in these built-boot goldens change from an expandable `button "Read …"`
to the read row's icon + Read + path-link shape. Refreshed keyless.

Subject: [PATCH 201/557] refactor(ui-conversation): extract shared toolview
 row-status helpers

SearchRow (this PR) and FileMutationRow (landed on master) independently carry
byte-identical rowStateStatus + rowResultText helpers, which the duplication gate
flags once both are present. Extract both into contract/toolview-status.ts and
consume them from both rows, deleting the clone rather than nudging it under the
threshold.

Subject: [PATCH 202/557] feat(session-query): expose projectSessions batch
 projection

Public SessionQueryService.projectSessions wraps the existing corpus
projectMany: one persistence listing, bounded persisted-inspect
concurrency, per-id failure isolation, and a synchronous projector over
a borrowed source with no replay validation or cloning.
readTitleSnapshots now routes through it; LogicalSessionSource and
LogicalProjectionResult are exported and documented.

 - `filterSessions(filters, signal?)` applies provider-independent session metadata and availability predicates to that same cloned logical corpus.
 - `filterEvents(sessionId, filters)` extracts first-party semantic documents and applies provider-independent metadata and literal-text predicates in ascending seq order.
 - `readTitleSnapshots(sessionIds, signal?)` resolves unique ids from one live-preferred corpus observation, passes cancellation through persisted listing and inspection, and returns ordered per-session settlements so one missing or malformed title source does not discard its peers. Each live source is folded directly, and each persisted worker folds to a detached header/title result and releases the full log before dequeuing another id. Cancellation rejects the whole batch. `readTitleSnapshot(sessionId, signal?)` is the one-observation view; `readTitle(sessionId, signal?)` returns only its optional folded `session/title`.
+- `projectSessions(sessionIds, project, signal?)` runs one synchronous caller fold per unique id under the same batched corpus observation, isolation, and cancellation rules as `readTitleSnapshots`. Each source is a borrowed raw log — never replay-validated or cloned — valid only for the projector call, so a batch summary (for example the resume selector) scales with what the projector retains instead of total log size; the projector must clone anything it keeps.
 - `listEvents(sessionId)` loads the live-preferred raw log and classifies each event as `current`, `shadowed`, or `log-only` with the shared `dsh-session` surface fold.
 - `readSurface(sessionId)` returns one cloned header, raw-log capture boundary, and the complete folded current surface in model-history order. A live session wins over persistence; compaction is observed before or after its replacement append, never as a synthetic mixture.
 - `readEvent(request, signal?)` returns a cloned header, the full target event, and a bounded raw-seq window. `before` and `after` default to zero and may not exceed `readWindowMax`.
 - `traceSession(sessionId, signal?)` reads the corpus once and returns immediate-to-outward ancestors plus deterministic recursive descendant trees. `complete: false` identifies the first missing parent; a target-connected cycle fails with `SESSION_QUERY_INVALID_LINEAGE`.
 - `traceEvent(request, signal?)` loads the logical log once and returns its cloned source header with direct positional replacements and direct logged provenance. `replacementChain` follows positional replacers to the final replacement; provenance links remain non-transitive.
 
-Persistence is optional and may mount or unmount dynamically. Cross-corpus listing and lineage tracing fail with `SESSION_QUERY_PERSISTENCE_FAILED` while mounted persistence is unreadable. A title read, event trace, or event read targeting a known live session does not consult persistence, so durable backend health cannot make current in-memory state unreadable. Persisted title and event operations list before loading and reject a metadata mismatch rather than combining inconsistent observations. Lineage-trace cancellation is passed to persisted listing; event-trace and event-read cancellation is passed to persisted listing and inspection. Each waits for the started backend call to settle, then rejects with the signal's exact reason even when the backend ignored that signal. A pre-aborted known-live title read, event trace, or event read rejects before folding or snapshotting without consulting persistence. A batch title observation performs one metadata listing, inspects its unique persisted ids with at most `persistedInspectConcurrency` workers, and preserves each title's own observed header for downstream authorization. Cancellation starts no queued inspections and rejects only after already-started workers settle. `listSessions()` remains lightweight and does not load logs or index titles.

 - `traceSession(sessionId, signal?)` 只读取一次语料库，返回从直接父级向外的祖先，以及确定性的递归后代树。`complete: false` 标识第一个缺失父级；与目标相连的循环会以 `SESSION_QUERY_INVALID_LINEAGE` 失败。
 - `traceEvent(request, signal?)` 只加载一次逻辑日志，返回其克隆源 header、直接位置替换和直接已记录来源信息。`replacementChain` 沿位置替换者跟踪到最终替换；来源链接仍不传递。

Subject: [PATCH 203/557] perf(tui): open the /resume selector from one batch
 projection

The selector called readSession per listed session under an unbounded
Promise.all: each call re-listed the whole persistence store (O(N^2)
listings), decompressed and parsed the complete log, replay-validated
every event, and deep-cloned it up to three times, only to derive one
row's title, activity time, turn label, route, and goal phase. On a
real 185-session / 87 MB store the selector took tens of seconds.

Candidate rows now come from one projectSessions batch over borrowed
logs; a rejected projection degrades to the same disabled unreadable
row. Preflight still replay-validates the single chosen session through
readSession, which is already live-preferred, so its redundant live
shortcut is gone.

+# Agent Note: Resume selector batch projection
+
+Status: implemented
+
+English | [中文](2026-07-31-resume-selector-batch-projection.zh.md)
+
+## Problem
+
+Opening the TUI `/resume` selector called `sessionQuery.readSession()` once per listed session under an unbounded `Promise.all`. Each call re-listed the whole persistence store inside `SessionCorpus.load()` (O(N²) listings), read and decompressed the complete log, replay-validated every event through the `Session` constructor, and deep-cloned the header and events up to three times — all to derive one selector row's title, last-activity time, last `turn/end` label, provider/model route, and goal phase. On a real store (185 sessions, 87 MB compressed, ~353k events) the selector took tens of seconds to open, and the cost grows with total log size rather than session count.
+
+## Decision
+
+`SessionQueryService` exposes the existing internal `SessionCorpus.projectMany` batch as public `projectSessions(sessionIds, project, signal?)`: one persistence listing, at most `persistedInspectConcurrency` concurrent persisted inspections, per-id failure isolation, and a synchronous projector over a borrowed `LogicalSessionSource` with no replay validation and no cloning. `readTitleSnapshots` now routes through it; `LogicalSessionSource` and `LogicalProjectionResult` are exported and documented in the session-query core-data-structures page.
+
+The `/resume` selector builds all candidate rows from one `projectSessions` batch; a rejected projection degrades to that row's disabled "Unreadable session" fallback exactly as a failed `readSession` did. `summarizeResumeCandidate` takes the borrowed source and retains only the record and derived scalars. The pre-handoff preflight still reads the single chosen session through `readSession`, keeping full replay validation before the process re-execs; its redundant live-session shortcut was dropped because `readSession` is already live-preferred.
+
+## Alternatives considered
+
+**Fix only the O(N²) listing inside `SessionCorpus.load()`.** Rejected as the primary fix: the per-candidate full decompress, replay validation, and triple clone dominate on large logs and remain O(total log bytes). The redundant pre-listing in `load()` is still a candidate cleanup, but it changes not-found/consistency error semantics and is not needed once the selector stops calling `readSession` per row.
+
+**A resume-specific summary method on `sessionQuery`.** Rejected: resume is a TUI concept, and the service seam should not import consumer vocabulary. The generic synchronous projection mirrors the seam `readTitleSnapshots` already used internally and lets the TUI own its fold.
+
+**A persisted summary index (e.g. in the SQLite query backend).** Rejected for now: one bounded pass over the store (~1–3 s on the measured machine) is acceptable selector latency, and an index adds an invalidation contract. Reintroduce if stores grow to where one bounded pass is still too slow.
+
+## Consequences
+
+Opening `/resume` performs one listing plus one bounded-concurrency pass instead of N listings and N validated full copies; memory stays bounded by the concurrency limit because each projected log is released before its worker dequeues another id. Selector rows are no longer replay-validated — a log that lists and parses but would fail replay shows as a normal row until preflight rejects it, which preflight always re-checks before handoff. Fake `sessionQuery` services in TUI tests must now provide `projectSessions` alongside `listSessions`/`readSession`.

+# Agent Note: 恢复选择器批量投影
+
+Status: implemented
+
+[English](2026-07-31-resume-selector-batch-projection.md) | 中文
+
+## Problem
+
+打开 TUI `/resume` 选择器时，会在一个无界 `Promise.all` 中对每个列出的会话调用一次 `sessionQuery.readSession()`。每次调用都会在 `SessionCorpus.load()` 内部重新列出整个持久化存储（O(N²) 次列表查询）、读取并解压完整日志、通过 `Session` 构造函数对每个事件做回放验证，并将 header 和事件深克隆多达三次——而这一切只为推导一行选择器条目的标题、最近活动时间、最后一个 `turn/end` 标签、提供方/模型路由和目标阶段。在真实存储上（185 个会话、压缩后 87 MB、约 35.3 万个事件），选择器需要数十秒才能打开，且开销随日志总大小而非会话数量增长。
+
+## Decision
+
+`SessionQueryService` 将既有的内部 `SessionCorpus.projectMany` 批量能力公开为 `projectSessions(sessionIds, project, signal?)`：一次持久化列表查询、最多 `persistedInspectConcurrency` 个并发持久化检查、按 id 隔离失败，以及一个在借用的 `LogicalSessionSource` 上运行的同步投影函数——不做回放验证也不克隆。`readTitleSnapshots` 现在经由它实现；`LogicalSessionSource` 和 `LogicalProjectionResult` 被导出，并记录在 session-query 核心数据结构页面中。
+
+`/resume` 选择器通过一次 `projectSessions` 批量调用构建全部候选行；被拒绝的投影会退化为该行的禁用"Unreadable session"回退，与之前 `readSession` 失败时的行为完全一致。`summarizeResumeCandidate` 接受借用的来源，且只保留记录和推导出的标量。移交前的预检仍通过 `readSession` 读取用户选中的单个会话，在进程 re-exec 前保留完整回放验证；其中冗余的实时会话捷径被删除，因为 `readSession` 本身已是实时优先。
+
+## Alternatives considered
+
+**只修复 `SessionCorpus.load()` 内部的 O(N²) 列表查询。** 作为主要修复被拒绝：在大日志上，按候选行执行的完整解压、回放验证和三重克隆才是主要开销，且仍是 O(日志总字节数)。`load()` 中的冗余预列表查询仍是一个候选清理项，但它会改变 not-found/一致性错误语义，而且一旦选择器不再按行调用 `readSession`，这项清理就不再必要。
+
+**在 `sessionQuery` 上添加恢复专用的摘要方法。** 被拒绝：恢复是 TUI 概念，服务接缝不应引入消费者词汇。通用同步投影复用了 `readTitleSnapshots` 已在内部使用的接缝，并让 TUI 拥有自己的 fold。
+
+**持久化摘要索引（例如放在 SQLite 查询后端中）。** 暂时被拒绝：对存储做一次有界扫描（在测量机器上约 1–3 秒）是可接受的选择器延迟，而索引会引入失效契约。若存储增长到一次有界扫描仍然过慢时再重新引入。
+
+## Consequences
+
+打开 `/resume` 只执行一次列表查询加一次有界并发扫描，而不是 N 次列表查询和 N 份经验证的完整副本；内存受并发上限约束，因为每个投影完的日志会在其 worker 出队下一个 id 前被释放。选择器行不再经过回放验证——一份可列出、可解析但回放会失败的日志会显示为普通行，直到预检拒绝它，而预检在移交前总会重新检查。TUI 测试中的伪造 `sessionQuery` 服务现在必须在 `listSessions`/`readSession` 之外提供 `projectSessions`。

Subject: [PATCH 204/557] feat(tui): hidden mode folds a turn's assistant steps
 into one message

The Ctrl+O hidden phase keeps one Assistant header per turn: the first
step with visible text/reasoning owns it, later steps render as
headerless continuations, and bodiless (tool-only) steps render
nothing. Leaving hidden restores per-step headers. Pure TUI
presentation; the session log is unchanged.

+# Agent Note: TUI hidden mode folds a turn's assistant steps into one message
+
+Status: implemented
+
+English | [中文](2026-07-29-tui-hidden-mode-assistant-fold.zh.md)
+
+## Problem
+
+Ctrl+O's hidden phase ([consolidated TUI presentation](../architecture/2026-07-28-consolidated-tui-presentation.md)) drops tool cards so the transcript reads as a conversation, but each model step still rendered its own `Assistant` header. A multi-step turn (text → tools → text) therefore showed several consecutive `Assistant` blocks with nothing between them — the removed tool cards were the only thing that had justified the repeated headers. Codex-style conversation-only reading wants one assistant message per turn.
+
+## Decision
+
+Hidden mode is also a fold rule, applied purely as TUI presentation: per turn, the first step whose rendered content is visible (text, or reasoning while reasoning display is on) owns the turn's single `Assistant` header; every other step renders as a headerless continuation, and a step with no visible body renders nothing at all — a tool-only step neither consumes the header nor leaves a blank segment. Collapsed and expanded phases keep per-step headers; leaving hidden restores them.
+
+Mechanics: `StreamingAssistantComponent` carries its `StepPosition` and a `setFoldedContinuation` presentation flag; `createTuiChat` keeps a per-turn list of step components and re-derives the fold on Ctrl+O, on each streamed text/reasoning chunk, on message settle, and on retraction of a failed stream (which may hand the header to the next step). Transcript rebuild clears the map and replays the log, so resume, compaction replacement, resize, and theme swaps converge on the same fold. Step timing footers keep their per-step ownership and are unaffected.
+
+## Alternatives considered
+
+- **Merge steps into one component** — collides with per-step streaming lifecycle, retry retraction, and timing footers; the flag on existing components changes only the header/spacer.
+- **Fold in the session log or `deriveMessages`** — mutates durable/model-visible history for a UI reading mode; the log stays step-shaped.
+- **Always fold (all visibility phases)** — collapsed/expanded interleave tool cards between steps, where per-step headers delimit which output belongs to which step.
+
+## Consequences
+
+Hidden mode now reads as one assistant message per turn; turns stay separated by their headers. The fold is recomputed state, never stored, so no session or persistence format changes. Coverage: TUI unit specs for the Ctrl+O cycle header counts, tool-only first step header handoff, per-turn separation, and live streaming + rebuild convergence; keyless snapshot `tool-cards-hidden-folded` pins the folded frame.

+# Agent Note: TUI 隐藏模式把一个轮次的 assistant 步骤折叠为一条消息
+
+Status: implemented
+
+[English](2026-07-29-tui-hidden-mode-assistant-fold.md) | 中文
+
+## 问题
+
+Ctrl+O 的隐藏阶段（[整合的 TUI 展示](../architecture/2026-07-28-consolidated-tui-presentation.md)）去掉工具卡片，让 transcript（文本记录）读作一段对话，但每个模型步骤仍渲染自己的 `Assistant` 标题。因此一个多步骤轮次（文本 → 工具 → 文本）会显示多个连续、之间空无一物的 `Assistant` 区块——被移除的工具卡片正是重复标题曾经的唯一理由。Codex 风格的纯对话阅读需要每轮次一条 assistant 消息。
+
+## 决定
+
+隐藏模式同时也是一条折叠规则，且纯粹作为 TUI 展示实现：在每个轮次内，第一个渲染内容可见（有文本，或在 reasoning 显示开启时有 reasoning）的步骤拥有该轮次唯一的 `Assistant` 标题；其余步骤渲染为无标题的续段，没有可见正文的步骤则完全不渲染——仅有工具调用的步骤既不占用标题，也不留下空白段。折叠与展开阶段保留每步各自的标题；离开隐藏阶段会恢复它们。
+
+机制：`StreamingAssistantComponent` 携带自己的 `StepPosition` 和一个 `setFoldedContinuation` 展示标志；`createTuiChat` 维护每轮次的步骤组件列表，并在 Ctrl+O、每个流式 text/reasoning chunk、消息结算，以及失败流被撤回（可能把标题移交给下一个步骤）时重新推导折叠。transcript 重建会清空该映射并重放日志，因此恢复、压缩替换、调整尺寸和主题切换收敛到同一折叠结果。步骤计时页脚保持按步骤归属，不受影响。
+
+## 考虑过的替代方案
+
+- **把多个步骤合并为一个组件**——与按步骤的流式生命周期、重试撤回和计时页脚冲突；在现有组件上加标志只改变标题与前导间距。
+- **在会话日志或 `deriveMessages` 中折叠**——为一种 UI 阅读模式改变持久 / 模型可见的历史；日志保持按步骤的形状。
+- **所有可见性阶段都折叠**——折叠 / 展开阶段在步骤之间穿插工具卡片，此时每步的标题用来划分哪段输出属于哪个步骤。
+
+## 后果
+
+隐藏模式现在每轮次读作一条 assistant 消息；轮次之间仍由各自的标题分隔。折叠是重新计算的状态，从不存储，因此会话与持久化格式没有变化。覆盖：TUI 单元测试覆盖 Ctrl+O 循环的标题计数、仅工具的首步骤标题移交、按轮次分隔，以及实时流式 + 重建收敛；无密钥快照 `tool-cards-hidden-folded` 固定折叠后的帧。

 When optional `ctx.sessionReferences` is mounted, the same `@` menu also offers metadata-only session candidates, inserts `@[label](dsh-session:)`, and prepares the selected snapshots before dispatch. Session references remain structured because the model has no filesystem-like tool for retrieving session snapshots later. Preparation disables duplicate submission and restores the editor input on failure. The TUI chooses `agent.steer()` or `agent.followup()` from the status after that asynchronous preparation, so idle follow-ups still dispatch `agent/prompt-submit` while in-turn steering joins at a checkpoint without that hook.
 
-While the agent is running, ordinary editor submissions call `agent.steer()`; otherwise they call `agent.followup()`. A slash at the start of the submitted line enters `ctx.commands` instead: known commands execute directly, unknown commands produce a warning, and neither path automatically reaches the model. A command producer may explicitly schedule agent work; [`dsh-plan-mode`](../../plan/plan-mode/README.md#model-and-human-surfaces) uses that contract for `/plan [message]`. The TUI registers `/help`, `/model`, `/clear`, `/palette`, `/reload`, `/resume`, `/status`, and `/exit` as agent-scoped definitions; every other effective command joins autocomplete and `/help` dynamically, as do `/skill:` completions. A status line above the editor reports the turn phase the TUI derives from session events — waiting for the first token, thinking, responding, or executing tools — with the elapsed time in that phase and the running step total, refreshed each second, and ends with the `Enter sends steering, Esc cancels` hint; while steering messages wait to reach the model it inserts a `N queued ·` badge before the hint that clears as each drains. Ctrl+C or Escape cancels a running turn. Tool and injected-context cards collapse long bodies into a configurable head/tail preview; Ctrl+O cycles tool cards through collapsed preview, full output, and hidden — the hidden phase drops tool cards from the transcript entirely while context cards stay at their preview, since injected instructions are not tool traffic. An injected-context card renders its message as prose with the producer's outer reminder frame stripped, so neither the fold nor the frame stripping depends on the payload's syntax. Ctrl+R toggles reasoning, Ctrl+L redraws, and Ctrl+D exits while idle.

 `/model` opens the advisory `ctx.llm` catalog as a keyboard selector: a filter box above the list narrows rows by a case-insensitive substring over each row's `provider/model` label, model name, and description, keeping the highlighted row selected when it survives the filter; Up/Down moves, Shift+Tab cycles the focused model's adapter-advertised reasoning efforts in display order, Enter selects the model and effort, and Escape clears a non-empty filter before a second Escape closes it. When an adapter does not advertise a default effort, the cycle also includes `Default`, which clears an explicit selection and preserves the provider default; models without selectable effort metadata ignore Shift+Tab. The selector renders the exact advertised effort list—including `off` when present—and does not synthesize, clamp, or transfer an effort between models. `/model ` still selects an unambiguous model id directly, while `/model /` selects an exact target and uses its adapter default when one exists. The configured target or latest logged request header initializes the selector, and an unlisted current model remains visible because catalogs are advisory. Selection is local to this TUI session. Prompt assembly snapshots the target for one step, replaces `{{provider}}` and `{{model}}`, and applies the same provider/model/reasoning-effort target through `agent/request`; a switch during assembly therefore starts with a later step. The request header durably records targets that reach the model, while an unused selection remains process-local.

 `/model` 将建议性的 `ctx.llm` catalog 打开为键盘选择器：列表上方设有一个过滤框，按对每行 `provider/model` 标签、模型名称和描述的大小写不敏感子串匹配来缩小行集，并在高亮行仍通过过滤时保持其选中状态；Up/Down 移动，Shift+Tab 按显示顺序循环切换适配器为焦点模型公布的推理强度，Enter 选择模型和推理强度，Escape 会先清除非空过滤内容，再次按下才关闭选择器。适配器未公布默认推理强度时，循环还会包含 `Default`，该项会清除显式选择并保留提供方默认行为；没有可选推理强度元数据的模型会忽略 Shift+Tab。选择器会原样呈现公布的推理强度列表（包括存在时的 `off`），不会合成、自动调整或在模型之间转移推理强度。`/model ` 仍可直接选择无歧义的模型 id，`/model /` 则选择精确目标，并在存在时使用其适配器默认值。已配置目标或最新记录的请求 header 会初始化选择器；由于 catalog 仅提供建议，未列出的当前模型仍会显示。选择仅对本 TUI 会话有效。提示词组装会为一个步骤建立目标快照，替换 `{{provider}}` 和 `{{model}}`，并通过 `agent/request` 应用同一个提供方／模型／推理强度目标；因此组装期间的切换会从后续步骤开始生效。请求 header 会持久记录真正到达模型的目标，未使用的选择则只存在于进程本地。

Subject: [PATCH 206/557] refactor(web-cards): route read/search/web/diff rows
 through collapsed ToolRow

The read, search, web, and file-mutation toolviews each hand-drew their own
summary-row chrome and kept their card (ReadBlock/SearchBlock/WebBlock/
DiffBlock) resident below the summary. Fold all four into the shared ToolRow:
ToolRow now takes read/search/web/diff card material alongside terminal, and
renders it in its collapsed-by-default expanded body, so every tool row shares
one expand interaction and starts collapsed. The GenericToolCard fallback and
the DetailsPanel Output section keep rendering the same cards (the panel at full
height); the per-row .module.css files are deleted as ToolRow owns the chrome.

The generic atom adds one optional behavior path and a one-second timer; it clears the timer on unmount and never reports a rejected write as success.

 The picker lists real Host Workspace entities through the global `useWorkspaces` hook. Selecting a Workspace invokes the slot owner's `onPick` callback to retarget the frontend Session object. Each registration declares a **directory-flow child hole** (`single` kind: `conversation.hero.workspace.directoryFlow` / `sidebar.workspaces.directoryFlow`) that the composed picker package's client half fills with its picking interaction — the [`-native`](../../host/directory-picker-native/README.md) backend's renderless OS-chooser driver today, an in-app browsing dialog under a `-browse` composition. The flat **Open local folder...** action renders only while the surface's hole is occupied (occupancy read per menu render; an empty hole means the composition has no picking affordance — the seam's documented no-flow default). This package owns the trigger and the adoption: the occupant reports one picked path per open through the hole's owner conversation (`open`/`busy`/`onPicked`/`onCancel`/`onError`), and the owner adopts it through the object layer, selecting the committed Workspace only after its list projection has refreshed; cancellation is silent, and errors land in the retryable folder dialog whose **Choose again** reopens the flow. **Create a new workspace** retains the name dialog and disables names already present in that list, while the Host remains authoritative for concurrent or non-UI callers. The runtime Session and Workspace services own materialization. The Workspace row's Delete action opens a confirmation that states the retention boundary, blocks duplicate submission, and keeps failures open; success removes the group while its Sessions remain under Ungrouped. The Session row's Rename action opens the same browser-owned dialog pattern prefilled with the row's display title: no client-side conflict rule exists (the host normalizes and may reject with `title-invalid`, rendered in the dialog alert), and confirming an unchanged title is deliberately allowed — it pins the current automatic title against regeneration. The Session row's Archive action commits without a confirmation dialog (non-destructive: the log and the workspace accounting slot remain) through `ctx.workspaces.archiveSession`; the row disappears from every grouping surface — workspace groups, Ungrouped, content search, and the flat list — when the archive-set echo lands, and failures are console diagnostics that leave the tree unchanged. A blank New Session row is a pure placeholder: it renders no row menu and no time label (nothing has happened in it yet), so rename, fork, and archive first apply once the first prompt lands.
 
-Workspace and Session hover cards copy the value their row clips: activating a Workspace card writes its full directory path, while activating a Session card writes its full display title. The card reports the dictionary-driven copied state only after the browser accepts the clipboard write.
+Workspace and Session hover cards copy the value their row clips: activating a Workspace card writes its full directory path, while activating a non-blank Session card writes its full display title. A provisional blank New Session card remains read-only because its localized label is a placeholder rather than session content. The card reports the dictionary-driven copied state only after the browser accepts the clipboard write.
 
 The Session row's Fork action forks at the source's last completed turn, increments the inherited persisted title on the client, and then opens the child; a trailing ASCII or fullwidth parenthesized number is incremented in the same style, while an unnumbered title gets ` (1)` appended. The source and child always appear as peer rows within a workspace group, with lineage retained only as session data. A fork or rename failure leaves the current selection unchanged; after a rename failure, the created child remains in the list.

 Session 行内的 Fork 操作在源会话最后一个已完成轮次处 fork，在 client 端递增继承的持久化标题后再打开子会话；尾部半角或全角括号编号会原样式递增，无编号标题追加 ` (1)`。源会话与子会话在 workspace 组内始终作为同级行展示，谱系只保留为 session 数据。Fork 或改名失败都不会改变当前选中项，改名失败时已创建的子会话仍会留在列表中。

booting; --dump-default-config stops at the surface overlay so the two
outputs diff to precisely the user layer's effect.

The dump shares the mounting code: the vendored include exports its
patch algorithm as applyEntryPatches() and its !!js dialect as
entryListSchema (logged in vendor/README.md), dsh-app-boot's
renderConfigDump() composes and renders through both (and now imports
the dialect instead of duplicating it), and the CLI adds a thin
dump-config mode. !!js expressions print verbatim; unmatched patches
warn on stderr; boot-only flags are rejected alongside the dump flags.

+# Agent Note: dsh --dump-config prints the composed config tree
+
+Status: implemented
+
+English | [中文](2026-07-30-dsh-dump-config.zh.md)
+
+## Problem
+
+The booted tree is a composition the user never sees: the shipped base, a surface overlay, and the `--config` or personal `~/.dsh/config.yaml` overlay apply as sibling patch lists where each id-targeted patch replaces the row's whole `config` and an unmatched id only warns. Debugging a misbehaving personal overlay (a restated field dropped, a row id typo, a patch applying to the wrong surface) required mentally replaying the patch algorithm across three files. There was no way to see the effective tree or to diff it against the shipped defaults.
+
+## Decision
+
+`dsh --dump-config` and `dsh web --dump-config` print the composed entry list — base, surface overlay, then the `--config` or personal overlay, exactly the layers that surface's boot assembles — as YAML on stdout and exit without booting. `dsh --dump-default-config` / `dsh web --dump-default-config` stop at the surface overlay, so diffing the two outputs shows precisely what the user layer changes.
+
+The dump cannot drift from what boots because it shares the mounting code: the vendored include exports its patch algorithm as the pure `applyEntryPatches(data, patches, warn)` (the private `applyPatches` method now delegates to it) and its `!!js` YAML dialect as `entryListSchema`; `dsh-app-boot`'s `renderConfigDump()` composes labeled layers and renders through both, and `apps/cli/src/dump-config.ts` is a thin surface-selection wrapper. `!!js` expressions print verbatim and unevaluated — the dump shows composition, not one process's environment — and a patch whose target row is absent goes to stderr with its layer label, mirroring the Loader's boot-time warning. Launcher-owned boot-context values (session identity, web CLI-flag patches, the frontend dist path) are per-invocation facts outside the config tree and do not appear. The dump flags reject boot-only flags (`-p`, `--resume`, `--config-replace`) and each other, and `--dump-default-config` takes no `--config`.
+
+Each run of same-provenance rows is preceded by a `# ==` comment naming the file that contributed the rows and the layers that patched them (`# == base.cordis.yml, patched by tui.cordis.yml`), so the output shows which section comes from which file while remaining one loadable YAML document. Composition is one flattened `applyEntryPatches` call over all layers — boot's exact call shape, so even patch-visibility corner cases (a later layer targeting a group child that a plain `config` replacement introduced, invisible to the single-pass id index) compose identically; applying one call per layer would rebuild the index between layers and print a tree boot never mounts. Provenance is derived from single-call prefix snapshots (base + layers 1..k) diffed positionally: the patch algorithm only rewrites rows in place or appends, so a top-level index identifies one row across snapshots, and a layer counts as having patched a row when adding it changed that row (config replacement, disable, group insert). Patch lists are cloned per snapshot because `applyEntryPatches` pushes `insert` rows by reference from the patch list.
+
+`dsh-app-boot` previously duplicated the include's `!!js` YAML type for patch parsing; it now imports `entryListSchema`, so the dialect has one owner.
+
+## Alternatives considered
+
+**Boot the tree and dump `ctx.loader.entries()`.** Rejected: booting evaluates `!!js` expressions (leaking one machine's environment into the printed config), starts adapters and sessions as side effects, requires a TTY-independent teardown path, and is slow. The dump is for debugging composition, which is a pure function of the files.
+
+**Reimplement the patch merge in the CLI.** Rejected: a second implementation of `applyPatches` would silently drift from the vendored include — the exact failure mode the feature exists to debug. Exporting the include's own algorithm costs one logged vendor modification and guarantees identity.
+
+**A `/dump-config` TUI command instead of flags.** Rejected as the only form: the primary use is a piped `dsh --dump-config | diff - <(dsh --dump-default-config)` style workflow, which needs a boot-free non-TTY surface. A TUI command can be added later over the same `renderConfigDump`.
+
+## Consequences
+
+Config debugging becomes one command instead of mental patch replay, and support can ask for `--dump-config` output. The vendored include carries one more logged local modification (the `applyEntryPatches`/`entryListSchema` exports; behavior-preserving for mounting) to re-apply on upstream sync. Provenance tracking re-composes one prefix snapshot per layer and diffs rows by JSON stringify, so the dump does extra work proportional to layers² × rows; that cost lives only in the boot-free dump path. `renderConfigDump` is unit-tested for layer ordering, verbatim `!!js` round-tripping, provenance separators and grouping, labeled unmatched-patch warnings, and loud read/parse/shape failures; the built-bin e2e drives all four flag forms through `lib/bin.js` including the personal-overlay layer, its provenance label, and its stderr warning.

+# Agent Note: dsh --dump-config 打印合成后的配置树
+
+Status: implemented
+
+[English](2026-07-30-dsh-dump-config.md) | 中文
+
+## Problem
+
+启动的配置树是一份用户从未见过的合成结果：已交付的基础配置、界面覆盖层，以及 `--config` 或个人 `~/.dsh/config.yaml` 覆盖层作为同级补丁列表依次应用，其中每个按 id 定向的补丁替换目标行的整个 `config`，未匹配的 id 只产生警告。调试一个行为异常的个人覆盖层（漏掉需要重述的字段、行 id 拼错、补丁应用到了错误的界面）需要在脑中跨三个文件重放补丁算法。既没有办法看到生效的树，也没有办法把它与已交付的默认值做 diff。
+
+## Decision
+
+`dsh --dump-config` 和 `dsh web --dump-config` 把合成后的条目列表——基础配置、界面覆盖层、再叠 `--config` 或个人覆盖层，恰好是该界面启动时组装的那些层——以 YAML 打印到 stdout 后退出，不启动任何东西。`dsh --dump-default-config` / `dsh web --dump-default-config` 止步于界面覆盖层，因此对两份输出做 diff 就能精确看出用户层改了什么。
+
+dump 不可能与实际启动漂移，因为它复用挂载代码：vendored include 把补丁算法导出为纯函数 `applyEntryPatches(data, patches, warn)`（私有的 `applyPatches` 方法现在委托给它），并把 `!!js` YAML 方言导出为 `entryListSchema`；`dsh-app-boot` 的 `renderConfigDump()` 通过这两者对带标签的层完成合成与渲染，`apps/cli/src/dump-config.ts` 只是选择界面的薄封装。`!!js` 表达式原样打印、不求值——dump 展示的是合成结果，不是某个进程的环境——目标行不存在的补丁会连同其层标签报到 stderr，与 Loader 启动时的警告一致。由启动器持有的启动上下文值（会话身份、web 的 CLI 标志补丁、前端 dist 路径）是每次调用的事实，位于配置树之外，不会出现。dump 标志拒绝仅用于启动的标志（`-p`、`--resume`、`--config-replace`）且两个 dump 标志互斥，`--dump-default-config` 不接受 `--config`。
+
+每段来源相同的连续行之前都有一条 `# ==` 注释，标明贡献这些行的文件以及修补过它们的层（`# == base.cordis.yml, patched by tui.cordis.yml`），因此输出既展示每一节来自哪个文件，又仍是一份可加载的 YAML 文档。合成是对所有层展平后的一次 `applyEntryPatches` 调用——与启动的调用形状完全一致，因此即便是补丁可见性的边角情况（后一层定位到前一层通过普通 `config` 替换引入的组内子项，而单遍 id 索引看不到它）也与启动合成完全相同；若按层各调用一次，会在层与层之间重建索引，打印出一棵启动从不挂载的树。来源从单次调用的前缀快照（基础 + 第 1..k 层）按位置 diff 得出：补丁算法只会原地改写行或在末尾追加，因此顶层索引在各快照之间标识同一行；加入某层后该行发生变化（替换 config、禁用、组内插入）即视为该层修补了这一行。每个快照都会克隆补丁列表，因为 `applyEntryPatches` 会把 `insert` 行按引用从补丁列表推入结果。
+
+`dsh-app-boot` 之前为解析补丁复制了 include 的 `!!js` YAML 类型；现在改为导入 `entryListSchema`，方言只有一个归属者。
+
+## Alternatives considered
+
+**启动整棵树后 dump `ctx.loader.entries()`。** 拒绝：启动会求值 `!!js` 表达式（把某台机器的环境泄漏进打印的配置）、以副作用启动适配器和会话、需要独立于 TTY 的拆卸路径，而且慢。dump 是用来调试合成的，而合成是那些文件的纯函数。
+
+**在 CLI 里重新实现补丁合并。** 拒绝：`applyPatches` 的第二个实现会与 vendored include 悄然漂移——这恰恰是该功能要调试的失败模式。导出 include 自己的算法只花费一条记录在案的 vendor 修改，却保证了同一性。
+
+**用 `/dump-config` TUI 命令代替标志。** 作为唯一形式被拒绝：主要用法是 `dsh --dump-config | diff - <(dsh --dump-default-config)` 这类管道工作流，需要免启动、非 TTY 的界面。之后可以在同一个 `renderConfigDump` 之上再加 TUI 命令。
+
+## Consequences
+
+配置调试从脑中重放补丁变成一条命令，支持工作也可以直接索要 `--dump-config` 输出。vendored include 多出一条记录在案的本地修改（导出 `applyEntryPatches`/`entryListSchema`；对挂载行为无影响），上游同步时需重新应用。来源追踪为每层重新合成一次前缀快照并按 JSON stringify 对行做 diff，因此 dump 有与层数²×行数成正比的额外开销；该开销只存在于免启动的 dump 路径。`renderConfigDump` 的单元测试覆盖层叠顺序、`!!js` 原样往返、来源分隔与分组、带标签的未匹配补丁警告，以及读取／解析／形状失败的大声报错；built-bin e2e 通过 `lib/bin.js` 驱动全部四种标志形式，包括个人覆盖层、其来源标签及其 stderr 警告。

 The Web and headless surfaces boot `base.cordis.yml` plus `web.cordis.yml`, then apply `$DSH_HOME/config.yaml`; an explicit `--config ` replaces that personal overlay. Both surfaces otherwise share the same composition: both treat the invoking directory as the default project and Workspace root, create named Workspaces beneath that root unless `--workspace-root ` overrides it, load applicable `AGENTS.md`/`CLAUDE.md` instructions into each agent-loop request prefix with a 65,536-byte render budget, opt into first-message model titles, use the same bounded transient model-request retry policy as the TUI, and mount a disposable in-memory SQLite content-index service. That service is ACTIVE at boot, while its `node:sqlite` module and database handle open only on the first content search. This keeps Node 22 startup output free of SQLite's experimental warning before search is used; the first actual search may still emit the runtime warning. Each service instance owns its database, so parallel invocations neither share unsupported SQLite state nor leave derived index files behind, and the first search lazily reconciles live and persisted logs. Headless differs only in listening on an OS-assigned port (parallel `dsh -p` runs never collide; the stderr-printed URL opens the live session in a browser). Both need the frontend dist and client bundles built (`pnpm run build && pnpm run build:web`).
 
 The shipped TUI and Web compositions register the native DeepSeek adapter plus pi-ai OpenAI and Anthropic profiles. Credentials and endpoint overrides come from the provider-standard `DEEPSEEK_API_KEY` / `DEEPSEEK_BASE_URL`, `OPENAI_API_KEY` / `OPENAI_BASE_URL`, and `ANTHROPIC_API_KEY` / `ANTHROPIC_BASE_URL` pairs in the boot's layered environment.

 TUI 界面：
 
@@ -17,6 +17,8 @@ TUI 界面：
 
 `dsh upgrade` 是默认 TUI 界面之上的引导式全新会话入口：它在调用目录中创建一个全新会话，并以内置 `dsh-upgrade` skill 播种其首轮，效果等同于用户手动键入 `/skill:`。启动器将 skill 名称提供到启动上下文（[`INITIAL_SKILL_KEY`](../../packages/ui/tui/README.md)），TUI 在聊天就绪后自动调用它。两者都不接受任何选项——`--config`、`-p`、`--resume` 都会明确报错——且仅在首次启动时播种，因此之后 `dsh --resume ` 恢复该会话时是普通 TUI 会话，不会重复注入。
 
+`dsh --dump-config` 和 `dsh web --dump-config` 把合成后的配置树——已交付的基础配置、界面覆盖层，以及 `--config` 或个人覆盖层，恰好是该界面启动时组装的那些层——以 YAML 打印到 stdout 后退出，不启动任何东西；`--dump-default-config` 止步于界面覆盖层，因此对两份输出做 diff 就能精确看出用户层改了什么。每段连续的行之前都有一条 `# ==` 注释，标明该段来自哪个文件以及被哪些层修补过（例如 `# == base.cordis.yml, patched by tui.cordis.yml`），因此输出既展示来源，又仍是一份可加载的文档。合成通过 include 自己的补丁算法和 YAML 方言（`@cordisjs/plugin-include` 的 `applyEntryPatches`/`entryListSchema`）完成，因此 dump 不可能与实际启动漂移；`!!js` 表达式原样打印、不求值，目标行不存在的补丁会连同其所在层报到 stderr，与 Loader 启动时的警告一致。由启动器持有的启动上下文值（会话身份、CLI 标志补丁）是每次调用的事实，位于配置树之外，不会出现。dump 标志会拒绝仅用于启动的标志（`-p`、`--resume`、`--config-replace`）而不是静默忽略它们，`--dump-default-config` 不接受 `--config`。
+
 Web 和无头界面启动 `base.cordis.yml` 与 `web.cordis.yml`，随后应用 `$DSH_HOME/config.yaml`；显式的 `--config ` 会替代该个人覆盖。除此之外，两者共享同一套组合：两者都将调用目录视为默认项目和 Workspace 根目录，除非通过 `--workspace-root ` 覆盖，否则会在该根目录下创建具名 Workspace；它们会把适用的 `AGENTS.md`/`CLAUDE.md` 指令加载到每个 agent-loop 请求前缀中，渲染预算为 65,536 字节，选用首条消息模型标题，采用与 TUI 相同的有界暂时性模型请求重试策略，并挂载一个可丢弃的内存 SQLite 内容索引服务。该服务在启动时处于 ACTIVE 状态，但其 `node:sqlite` 模块与数据库句柄分别要到首次内容搜索才会导入和打开。这样可使 Node 22 在尚未使用搜索时的启动输出不出现 SQLite 实验性警告；首次实际搜索仍可能发出运行时警告。每个服务实例独占自己的数据库，因此并行调用既不会共享不受支持的 SQLite 状态，也不会留下派生索引文件，首次搜索还会惰性对账实时日志与持久化日志。无头界面唯一的差异是监听操作系统分配的端口（并行 `dsh -p` 运行绝不冲突；stderr 打印的 URL 会在浏览器中打开实时会话）。两者都需要先构建前端 dist 和客户端 bundle（`pnpm run build && pnpm run build:web`）。
 
 已交付的 TUI 和 Web 组合会注册原生 DeepSeek 适配器，以及 pi-ai 的 OpenAI 和 Anthropic 提供方配置。凭据和端点覆盖来自启动分层环境中的提供方标准变量对：`DEEPSEEK_API_KEY` / `DEEPSEEK_BASE_URL`、`OPENAI_API_KEY` / `OPENAI_BASE_URL` 和 `ANTHROPIC_API_KEY` / `ANTHROPIC_BASE_URL`。

 8. **`include/src/index.ts` hot-reload hardening**: `refresh()` awaits the full read-and-update and catches failures (logging a warning and keeping the last good entry tree) instead of rethrowing — upstream's throw escaped `@cordisjs/plugin-hmr`'s async watcher callback as an unhandled rejection, so one bad `cordis.yml` edit killed a live app. `read()` rejects a non-array parse result (an empty or mid-write truncated file parses to `undefined`, which upstream later crashed on) and commits `content`/`data` only on success, so reverting an edit to the exact last good content reads as "unchanged". `refresh()` and the `internal/update` listener re-apply `config.patches` before `root.update()`, matching initial load; upstream applied patches only in `[Service.init]`, so any config hot-reload silently reverted overlay-patched entries and removed inserted ones. `applyPatches` deep-copies via `structuredClone` instead of mutating the cached parse (repeated application converges; removing a patch reverts), and the veto-style `internal/update` listener persists the incoming config itself (`Fiber.update` only assigns behind `next()`), so later re-reads use the new patches. `[Service.init]` falls back to `initial` only on `ENOENT`; an existing-but-invalid file fails loud with its real parse error instead of "config file not found" (or a silent overwrite). `applyPatches` also indexes each `insert`ed entry as it is added, so a later patch in the same list can configure or disable a row an earlier patch inserted; upstream built the id index once before the patch loop, leaving inserted rows silently unpatchable. That matters because `dsh` composes one shared base (`apps/cli/config/base.cordis.yml`) with a surface overlay, an optional `--config` overlay, and the personal `~/.dsh/config.yaml` as sibling patch lists at one include level — patches never cross an include boundary, so surface-only rows would otherwise be unreachable from user config. Covered by `packages/ui/app-boot/tests/config-reload.spec.ts`.
 9. **Vendored Node-compatible TypeScript**: marked erased imports explicitly across `cordis`, `loader`, `include`, `hmr`, and `schemastery` so Node's native TypeScript transform does not request types as runtime exports. Schemastery's source uses an ESM default export and its package declares `type: module`; its built ESM/CJS entries retain explicit `.mjs`/`.cjs` extensions.
+10. **`include/src/index.ts` patch-semantics export**: extracted the private `applyPatches` body into the exported pure function `applyEntryPatches(data, patches, warn)` (the method delegates to it) and exported the `!!js` YAML dialect as `entryListSchema`, so `dsh --dump-config` composes and prints exactly what the include would mount without booting a tree. Behavior-preserving for mounting; the extraction exists because config tooling must never reimplement (and drift from) the patch algorithm.

Subject: [PATCH 210/557] cleanup(web): drop the unimplemented user-message
 edit control

The user bubble's IconActions row carried an edit button with no click
handler, no client mutation, and no host operation behind it, advertising
an affordance the product cannot honor. The row now renders clock / copy /
branch only for both user and assistant chrome, and MessageIconActions
loses the `edit` prop with the button.

The package README records the missing capability under Known Limitations,
the web aria goldens pin the row without the control, and the Agent Note
states what must exist before it comes back.

+# Agent Note: Drop the user-message edit stub

+Status: implemented

+
+## Problem
+
+The user bubble's IconActions row carried an edit button beside copy and branch. Nothing backed it: the control had no click handler, no client mutation, and no host operation for resending an edited message. A user who found it saw an affordance the product cannot honor.
+
+## Decision
+
+`MessageIconActions` renders clock / copy / branch only, and its `edit` prop is gone with the button; `MessageItem` no longer passes it. The user bubble and the assistant chrome now differ only by clock side. The package README records the missing capability under Known Limitations, and the web message-actions golden pins the row without the control.
+
+The common locale keeps its generic `edit` term, which is shared vocabulary rather than this component's copy.
+
+Reintroduce the control together with the capability: a client mutation that edits a settled user message and the host behavior that decides what the edited message does to the turn that already consumed it.
+
+## Alternatives considered
+
+**Disable the button with a tooltip.** A visible-but-dead control still advertises editing and costs the same explaining; removal is the honest state.
+
+**Wire it to the queue editor.** The queue edits a message that has not been sent. A settled user message is already in the transcript and in the model's context, so reusing that editor would silently mean something else.
+
+## Consequences
+
+Web offers no way to correct a sent message; branching from the message is the nearest available gesture. Reintroduction is a UI-only change once the mutation exists, since the row composes its actions from props.

+# Agent Note: 移除 user 消息的编辑存根
+
+Status: implemented
+
+[English](2026-07-31-drop-user-message-edit-stub.md) | 中文
+
+## 问题
+
+user 气泡的 IconActions 行在复制和分支旁边还有一个编辑按钮，但其背后什么都没有：该控件没有点击处理、没有 client 侧变更，也没有 host 侧重新发送已编辑消息的操作。用户找到它时，看到的是一个产品无法兑现的可供性。
+
+## 决策
+
+`MessageIconActions` 只渲染时钟／复制／分支，其 `edit` prop 随按钮一并删除；`MessageItem` 不再传入该 prop。现在 user 气泡与 assistant chrome 只在时钟位置上不同。包 README 在 Known Limitations 中记录这项缺失的能力，web 的 message-actions 金样固定了不含该控件的动作行。
+
+公共 locale 保留通用的 `edit` 词条：它是共享词汇，而非本组件的文案。
+
+重新引入该控件时要与能力一起落地：既需要编辑已定稿 user 消息的 client 变更，也需要 host 侧决定这条编辑后的消息对已经消费过它的轮次意味着什么。
+
+## 曾考虑的替代方案
+
+**把按钮置灰并加提示。** 一个可见但无效的控件仍在宣告可以编辑，解释成本相同；直接移除才是诚实的状态。
+
+**接到队列编辑器上。** 队列编辑的是尚未发送的消息。已定稿的 user 消息已经进入转录和模型上下文，复用该编辑器会让同一个动作悄悄变成另一件事。
+
+## 后果
+
+Web 没有任何途径修正已发送的消息；从该消息分支是最接近的现有手势。由于动作行的内容完全由 props 组合而来，能力就绪后重新引入只是一次纯 UI 改动。

 - **Stats-line durations cover the in-window flow only** — LLM and tool wall times fold the snapshot's assistant `timing` and tool call/result pairs, so nodes outside the loaded event window (older history) are not counted.
 - **Details panel is the minimal form and currently has no entry point** — selected call args/result raw display; the Input/Output/Metadata switch, Prev/Next stepping, and See-in-trajectory deep link are deferred. Tool rows stopped being details-panel click targets and nothing replaced that gesture, so `ChatViewInjected.openDetails` is implemented but uncalled and the panel (including its terminal card) is unreachable in the assembled application; its rendering stays covered by mounting it with a selection directly.
 - **Assistant per-message paging is a reserved slot** — drawn in the design, not implemented. The finalized content IconActions row (copy / branch / clock) ships under the last content-text assistant of each turn only; mid-turn narration and Think-only nodes stay chrome-free. Branch forks through the turn containing that message, increments the inherited title on the client, and then opens the child, while a fork or rename failure leaves the source selected.
+- **Sent user messages cannot be edited** — the user bubble's IconActions row carries clock / copy / branch only. The design's edit control shipped as a stub that no click handler backed, and it was removed until resending an edited message exists end to end ([decision](../../../.agents/notes/implemented/simplification/2026-07-31-drop-user-message-edit-stub.md)).
 - **The sparkle icon for the others tool row is a hand-drawn approximation** — the design glyph's vector geometry is not exportable locally; promotion into ui-primitives waits on an exact export.
 - **The approval panel's "Always allow this type" is deferred** — durable grants need a grant-storage design; only allow-once/reject answer today.
 - **TodoPanel truncates long item text to one ellipsized line** — the figma strip has no wrap or expand affordance; full text is not readable inline.

 - **assistant 逐消息分页是预留 slot**：设计中已有图稿，尚未实现。已定稿的内容 IconActions 行（复制／分支／时钟）只挂在每个轮次中最后一条带 text 内容的 assistant 下；轮次中间的叙述与纯 Think 节点不带 chrome。分支会 fork 到包含该消息的轮次末尾，在 client 端递增继承标题后打开子会话，而 fork 或改名失败时源会话保持选中。

Subject: [PATCH 211/557] fix(web): address the review round on the one-route
 add flow
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- lifecycle-chrome's second scaffold staged its workspace under the OUTER
  scaffold's temp root, coupling two supposedly independent worlds and
  leaving the aria scrub root wrong; it now uses its own workspaceCwd.
- The direct-open path now carries the same `flowBusy` gate that disables
  the equivalent menu entry, so an occupant re-registering mid-adoption
  cannot raise a second flow.
- A composition with no directory-picker no longer opens a zero-entry
  popover on the hero anchor: with nothing to pick and nothing to add,
  the gesture shows nothing. Both behaviors gain a unit test.
- Brought three partially superseded Agent Notes current (the native
  picker, the workspace UI product flow, and the sidebar browsing split),
  cross-linked to this decision, both languages re-recorded.
- Corrected this Note's own Testing section: the shared e2e helper stages
  and adopts its directory, it does not create one in-dialog — only
  workspace-management does. Named the client-seam and CLI-README residue
  in the follow-up TODO alongside the wire branch.

This is the seam's documented no-flow default reaching its conclusion: with the occupant gone, so is the only creation affordance. The hero's anchor chip belongs to ui-conversation, so this package can suppress the popover but cannot hide the chip.

+`connectFreshWorkspace` — the helper every web e2e scenario boots through — stages `/workspace` and adopts it through the dialog's path editor, so the produced session cwd stays identical to what create-by-name produced and scenario goldens stay valid. Staging rather than creating in-dialog keeps the helper idempotent across the repeated connects a scenario may make (a second create of the same folder fails, and the create dialog holds the flow open on that failure). Creating a folder from inside the chooser — the other half of the same route — is covered by `workspace-management.e2e.ts`, which owns the focused coverage: two workspaces added on folders the dialog creates, a deleted title reused on a different directory, and the browser-dialog aria golden.
+
+`smoke-real.e2e.ts` is the one scenario booting the unpatched shipped tree, where the `-auto` row resolves per host; it now pins `-browse` through a `--config` overlay so the developer's display environment cannot decide whether the picker is drivable at all.

Every scenario now walks the real dialog to adopt its directory; only the create-a-folder half is concentrated in one scenario, because repeating it everywhere makes the shared helper non-idempotent for no extra signal.
 
 ## Consequences
 
 - Creating a Workspace outside the operator's chosen directory is no longer possible from the UI; the server-controlled `--workspace-root` target was the one way to constrain where new workspace folders land, and nothing replaces it. A deployment that needs that constraint has to re-introduce it deliberately.
 - The one remaining route browses the host filesystem, so the picker's reach is now the whole host rather than one configured parent. That is already the browse occupant's contract; this change makes it the only contract.
 - A composition that mounts `ui-workspace` without any directory-picker package can no longer add a Workspace at all, and now says so by omitting the button instead of offering a create-by-name fallback.
+- The hero chip still announces `aria-haspopup="menu"` while the direct-open path raises a dialog instead. Making that truthful means routing the flow's presentation choice up through the `conversation.hero.workspace` owner contract — the flow owns the decision, the chip owns the announcement, and they sit in different packages — so it is a named follow-up rather than a silent inconsistency. The sidebar button this change added makes no popup claim at all.

-`connectFreshWorkspace`——所有 web e2e 场景启动时都会走的辅助函数——现在驱动真实对话框：路径编辑器 → **新建文件夹** → **创建** → **打开**。这让产出的路径（`/workspace`）与按名称创建时完全一致，因此场景 golden 保持有效；同时它把幸存的创建路径放到了整条 lane 的每个场景之下，而不只是某一个场景。`workspace-management.e2e.ts` 承担针对性覆盖（在自己创建的文件夹上添加两个 workspace、在另一个目录上复用已删除的标题、浏览对话框的 aria golden）。
+`connectFreshWorkspace`——所有 web e2e 场景启动时都会走的辅助函数——会预先备好 `/workspace`，再经对话框的路径编辑器接纳它，因此产出的会话 cwd 与按名称创建时完全一致，场景 golden 保持有效。选择预先备好而不是在对话框内新建，是为了让该辅助函数在一个场景可能发生的多次连接之间保持幂等（第二次创建同名文件夹会失败，而创建对话框会在失败时把流程停在原地）。在选择器内新建文件夹——同一条路径的另一半——由 `workspace-management.e2e.ts` 覆盖，它承担针对性覆盖：在对话框自己创建的文件夹上添加两个 workspace、在另一个目录上复用已删除的标题、以及浏览对话框的 aria golden。
+
+`smoke-real.e2e.ts` 是唯一启动未打补丁的出厂配置树的场景，其中 `-auto` 行会按宿主机解析；它现在通过 `--config` overlay 钉死 `-browse`，使开发机的显示环境无法决定选择器是否可被驱动。

 **在同一改动中删除 wire 的按名称创建分支。** 本 PR 否决：那是 backend/CLI 面，reviewer 不同、测试波及面更广，而紧急的决定是 UI。见 residue 一节——它是被标记了，不是被遗忘了。
 
-**在 e2e scaffold 中旁路种入 workspace，而不驱动对话框。** 否决：那会让 15 个场景彻底与选择器解耦，使产品唯一的创建路径只剩一个场景覆盖。驱动真实对话框每个场景多花几次交互，换来的是处处都有覆盖。
+**在 e2e scaffold 中经 host 注册 workspace，而不驱动对话框。** 否决：那会让全部 15 个场景与选择器解耦，整条 lane 将无法证明幸存的这条路径能走到可用的 composer。现在每个场景都会走真实对话框来接纳自己的目录；只有"新建文件夹"那一半集中在一个场景里，因为处处重复只会让共享辅助函数失去幂等性，却换不来额外信号。
 
 ## Consequences
 
 - 从 UI 已无法在操作者选定目录之外创建 Workspace；服务端控制的 `--workspace-root` 目标曾是约束新 workspace 文件夹落点的唯一手段，现在没有替代品。需要该约束的部署必须有意识地重新引入它。
 - 仅存的这条路径会浏览宿主机文件系统，因此选择器的可达范围现在是整台宿主机，而非一个配置好的父目录。这本就是浏览占用者的契约，本改动使它成为唯一的契约。
 - 挂载了 `ui-workspace` 但未挂任何 directory-picker 包的组合，已完全无法添加 Workspace；现在它通过不渲染按钮来说明这一点，而不是提供一个按名称创建的兜底。
+- 主视觉区的 chip 仍声明 `aria-haspopup="menu"`，而直接拉起的路径实际弹出的是对话框。要让它如实，需要把流程的展示方式经 `conversation.hero.workspace` 的 owner 契约上报——决定权在流程，播报权在 chip，两者分属不同的包——因此这被列为一项具名的后续工作，而不是一处无声的不一致。本次新增的侧边栏按钮完全不作任何 popup 声明。

+# Agent Note: TUI model-context resolution defers on the adapter-registration race
+
+Status: implemented
+
+English | [中文](2026-07-30-tui-adapter-registration-race.zh.md)
+
+## Problem
+
+Cordis activates plugins by service availability, not configuration order, so the TUI (whose `inject` requires only the `llm` service) can mount before a configured adapter plugin such as `dsh-llm-pi-ai` finishes registering its provider routes. The TUI's model controller resolves the selected model's context window immediately on mount; when the agent's route pointed at a not-yet-registered provider, `resolveModelInfo` rejected with `NO_ADAPTER` and every fresh session printed `Could not resolve model context: no adapter registered for provider "…"` — a spurious error for a fully working configuration (the adapter registered milliseconds later, and chatting worked).
+
+## Decision
+
+The TUI model controller treats a `NO_ADAPTER` rejection of its context-window resolution as a transient state rather than an error: it parks the resolution silently and re-resolves on the next `llm/adapters-updated` commit — the payload-free registry notification `LlmService` already fires at every route commit point. A commit that still lacks the route parks the wait again, so unrelated topology changes stay silent. Any target change re-enters the resolution and clears the pending wait, so the deferred state can never go stale against the current selection; every other resolution error still prints the notice.
+
+## Alternatives considered
+
+**Have the TUI wait for boot to settle before resolving.** The TUI has no Loader dependency (tests and embedders run without one) and "settled" is not observable from inside a plugin; adding a Loader coupling for one cosmetic resolution inverts the dependency direction.
+
+**Poll or retry with a timer.** A timer guesses at activation latency, still mis-prints on a slow adapter, and adds a tunable with no owner. The registry already announces every commit through `llm/adapters-updated`; subscribing is precise and free.
+
+**Order the config so adapters load first.** Row order carries no load semantics in the Loader (activation is service-driven by design), so this cannot be expressed in configuration.
+
+**Suppress NO_ADAPTER errors entirely.** A permanently missing adapter (typo in the provider name) would then never surface in the context-window path. Deferring keeps the signal: a wrong provider name still shows `model unset`-like behavior in the selector and fails loudly at dispatch, while the startup race resolves itself.
+
+**Resolve the context window per submitted message instead of at mount.** The send path already resolves per step (`prepareCall()`), and the indicator is displayed continuously, not only when sending; per-submit display resolution would leave the indicator blank until the first message and re-run adapter I/O for a value that only changes on route changes.
+
+## Consequences
+
+A genuinely misconfigured provider no longer prints the context-resolution error at startup — it surfaces at first dispatch instead, which is where the failure is actionable. The controller subscribes to every `llm/adapters-updated` commit but acts only while a wait is parked; the listener's disposer is released by the channel's `detachListeners()` through the controller's `detach()`, symmetric with the sibling channel listeners. Covered by three TUI tests: the deferred resolution stays silent through an unrelated commit and completes when the route's commit arrives, a target change drops the stale wait, and after channel detach a registry commit no longer re-enters resolution.

+# Agent Note: TUI 模型上下文解析在适配器注册竞争时延后重试
+
+Status: implemented
+
+[English](2026-07-30-tui-adapter-registration-race.md) | 中文
+
+## Problem
+
+Cordis 按服务可用性而非配置顺序激活插件，因此 TUI（其 `inject` 只要求 `llm` 服务）可能在 `dsh-llm-pi-ai` 这类已配置的适配器插件完成提供方路由注册之前就挂载。TUI 的模型控制器在挂载时立即解析所选模型的上下文窗口；当 agent 的路由指向尚未注册的提供方时，`resolveModelInfo` 以 `NO_ADAPTER` 拒绝，于是每个新会话都会打印 `Could not resolve model context: no adapter registered for provider "…"` —— 对一份完全正常的配置报出的虚假错误（适配器几毫秒后就完成注册，对话也一切正常）。
+
+## Decision
+
+TUI 模型控制器把上下文窗口解析中的 `NO_ADAPTER` 拒绝视为瞬态状态而非错误：静默搁置这次解析，并在下一次 `llm/adapters-updated` 提交时重新解析——这是 `LlmService` 本就在每个路由提交点发出的无载荷注册表通知。若某次提交仍缺少该路由，等待会被再次搁置，因此无关的拓扑变化保持沉默。任何目标变更都会重新进入解析并清除挂起的等待，因此延后状态绝不会相对当前选择变陈旧；其他所有解析错误仍照常打印通知。
+
+## Alternatives considered
+
+**让 TUI 等启动结算后再解析。** TUI 不依赖 Loader（测试和嵌入方在没有 Loader 的环境下运行），而且"已结算"在插件内部不可观测；为一次外观性的解析引入 Loader 耦合会颠倒依赖方向。
+
+**用定时器轮询或重试。** 定时器只能猜测激活延迟，遇到慢适配器仍会误报，还会引入一个没有归属者的可调参数。注册表本就通过 `llm/adapters-updated` 公告每次提交；订阅它既精确又零成本。
+
+**调整配置顺序让适配器先加载。** Loader 中行顺序不承载加载语义（激活按设计由服务驱动），因此这无法用配置表达。
+
+**彻底压制 NO_ADAPTER 错误。** 那样的话，永久缺失的适配器（提供方名字拼错）在上下文窗口路径上就永远不会暴露。延后重试保留了信号：错误的提供方名字仍会在选择器中表现出类似 `model unset` 的行为，并在分派时大声失败，而启动竞争则自行化解。
+
+**改为在每次提交消息时解析上下文窗口，而不是在挂载时。** 发送路径本就按步解析（`prepareCall()`），且指示器是持续显示的，不只在发送时；按提交解析显示值会让指示器在首条消息之前一直空白，并为一个仅在路由变化时才变的值反复执行适配器 I/O。
+
+## Consequences
+
+真正配置错误的提供方不再在启动时打印上下文解析错误——它改在首次分派时暴露，那才是该失败可以被处理的地方。控制器订阅每次 `llm/adapters-updated` 提交，但只在有等待被搁置时才动作；监听器的 disposer 经由控制器的 `detach()` 在频道的 `detachListeners()` 中释放，与同级频道监听器保持对称。由三个 TUI 测试覆盖：延后的解析在无关提交中保持沉默、在该路由的提交到来时完成；目标变更丢弃陈旧等待；频道 detach 之后注册表提交不再重新进入解析。

+# Agent Note: Compaction checkpoints use an English engineering register
+
+Status: implemented
+
+English | [中文](2026-07-31-english-compaction-checkpoints.zh.md)
+
+## Problem
+
+A compaction checkpoint becomes part of the next model request's durable prefix. When a multilingual conversation leads the compactor to preserve its narrative material in the conversation language, the checkpoint can introduce a large amount of a language that is absent from the code, tool output, and existing reasoning prefix. That language then persists across later compaction cycles and can influence the conversation model's reasoning register.
+
+## Decision
+
+`COMPACTION_INSTRUCTION` requires an English-language internal engineering checkpoint. It asks the model to translate narrative source material as needed while preserving exact literals, including paths, commands, errors, identifiers, signatures, and quoted wording when exactness matters. The checkpoint's headings and terse engineering bullets remain the existing structured format.
+
+The requirement is integrated into the first sentence of the trailing compaction instruction. The replayed system prompt, tools, and conversation history remain byte-identical to the routed request, so the change retains the prefix-cache reuse owned by the [compaction summary prefix-cache note](2026-07-21-compaction-summary-prefix-cache-reuse.md).
+
+## Alternatives considered
+
+- **Leave checkpoint language to the replayed conversation** — rejected: the checkpoint is a durable prompt prefix, so preserving a transient conversational register can amplify it across later compactions.
+- **Constrain the conversation model's language** — rejected: the policy is for an internal checkpoint, not the user's visible conversation, and a conversation-wide rule would unnecessarily change normal interaction.
+- **Require ASCII-only output** — rejected: ASCII is a character-set constraint rather than an engineering-register constraint and would unnecessarily distort legitimate literals and technical material.
+- **Append a separate final English-only sentence** — rejected: stating the requirement in the instruction's opening output contract is shorter and ties it directly to the checkpoint being requested.
+
+## Consequences
+
+- New checkpoints normalize narrative context into English while retaining the exact strings that future tool use and code work depend on.
+- Existing checkpoint structure, compaction routing, and cache alignment are unchanged; only the final user instruction is different.
+- The direct summarization call remains outside transcript snapshots because it emits no `assistant/chunk` events. The real-loop regression instead asserts the exact final instruction received by the summarization request.

+# Agent Note: 压缩检查点使用英语工程文体
+
+Status: implemented
+
+[English](2026-07-31-english-compaction-checkpoints.md) | 中文
+
+## 问题
+
+压缩（compaction）检查点会成为下一次模型请求中持久存在的前缀。当多语言对话使压缩器以对话语言保留叙述性材料时，检查点可能引入大量代码、工具输出和既有推理（reasoning）前缀中均未出现的语言内容。该语言随后会在后续压缩周期中持续存在，并影响对话模型的推理文体。
+
+## 决策
+
+`COMPACTION_INSTRUCTION` 要求生成英语的内部工程检查点。它要求模型在必要时翻译叙述性源材料，同时保留精确的字面量；这包括路径、命令、错误、标识符、签名，以及精确性重要时的引用措辞。检查点的标题及简洁的工程项目符号仍沿用既有的结构化格式。
+
+这项要求被整合到尾部压缩指令的第一句话中。回放的系统提示词、工具和对话历史与已路由请求保持字节级一致，因此该变更保留 [compaction summary prefix-cache note](2026-07-21-compaction-summary-prefix-cache-reuse.md) 所确立的前缀缓存复用。
+
+## 考虑过的替代方案
+
+- **让回放的对话决定检查点语言**——不采纳：检查点是持久的提示词前缀，保留短暂的对话文体可能在后续压缩中放大这种影响。
+- **约束对话模型的语言**——不采纳：该策略针对内部检查点，而不是用户可见的对话；对整个对话施加规则会不必要地改变正常交互。
+- **要求仅输出 ASCII**——不采纳：ASCII 是字符集约束，而非工程文体约束，并会不必要地扭曲合法的字面量和技术材料。
+- **在末尾追加一句独立的仅限英语要求**——不采纳：在指令开头的输出契约中说明该要求更简洁，也直接将其与所请求的检查点绑定。
+
+## 后果
+
+- 新检查点会将叙述性上下文规范化为英语，同时保留未来工具使用和代码工作所依赖的精确字符串。
+- 既有检查点结构、压缩路由和缓存对齐保持不变；只有最后一条 user 指令不同。
+- 直接摘要调用仍不纳入 transcript（文本记录）快照，因为它不会发出 `assistant/chunk` 事件。真实循环回归改为断言摘要请求收到的精确最终指令。

+# Agent Note: Search render intent — grep and glob emit a structured search card
+
+Status: implemented
+
+English | [中文](2026-07-30-search-render-card.zh.md)
+
+## Problem
+
+`grep` and `glob` return structured canonical values — `grep` a flat `{ matches: [{ path, lineNumber, line }] }`, `glob` a `{ paths: string[] }` — but every UI only ever saw their model-facing render text: `grep` groups its matches under file headers with `Line N:` rows, `glob` prints a newline-joined path list, and both append a spill footer when the inline cap (`grepMaxMatches`, default 250; `globMaxResults`, default 100) drops later results to a spill file. A web frontend that wants to render a search result as an expandable per-file group of matches, or as a selectable path list, had to re-parse that text. Both tools already declared a call-time [render intent](../architecture/2026-07-02-tool-render-intent-union.md) (`GenericCallView`, `kind: 'search'`) but no result-time view, so the completed call fell back to the generic card that renders the raw text.
+
+The structured canonical value does not cross the wire: only the model-facing render text and, when a tool declares `output.presentationMeta`, a JSON metadata payload reach the client, threaded through the `tool/result` event ([canonical-output contract](../architecture/2026-07-20-canonical-tool-output-contract.md)). A result-time view carrying structured data therefore has to project that data into `presentationMeta` and read it back in `presentResult` — the same path `write`/`edit` use for their diff cards.
+
+## Decision
+
+`packages/core/tools/src/presentation.ts` adds `card: 'search'` to the `ToolResultView` union as `SearchResultView`, a `shape`-discriminated view that expresses both tools' shapes: `SearchMatchesResultView` (`shape: 'matches'`) carries `grep`'s matches grouped by file as `files: { path, matches: { lineNumber, line }[] }[]`, and `SearchPathsResultView` (`shape: 'paths'`) carries `glob`'s flat `paths: string[]`. Both carry `truncated: boolean` and `total: number`.
+
+The discriminant is `shape`, not `kind`, deliberately: the same presentation module already gives `GenericCallView` a `kind: ToolCallKind` field whose values include `'search'` (the icon category). A bridge holding a `ToolCallView | ToolResultView` would see two `kind` fields with two meanings; `shape` for the result variant keeps the two apart.
+
+One view with two shapes rather than two cards, because both tools are the same visual object — a search result — and a web consumer switches on one `card` value, then on `shape` for the row layout. The discriminated `shape` keeps each variant's fields non-optional (a matches view always has `files`, a paths view always has `paths`) instead of a single interface where every shape-specific field is optional.
+
+The view carries **no** result text. An earlier revision attached the model-facing `result.content` to the view; that was a no-op for every consumer (the TUI already falls back to `result.content`, and web fallbacks read the raw `tool/result` content), and it serialized the whole search text a second time into the persisted view. The view is the structured shape only; a UI without a search card falls back to the raw `tool/result` content.
+
+The card tag is result-time only. A search call stays a `GenericCallView` (`kind: 'search'`): the pending state has no matches or paths to show, so there is nothing a `SearchCallView` would carry that the generic title does not. This is the asymmetry with the terminal card, whose call view carries the command, cwd, and description that exist before execution; a search's structured content exists only after `execute`.
+
+`packages/fs/tool-fs-search/src/presentation.ts` owns the projection and the narrowing. `grepSearchMeta`/`globSearchMeta` project the canonical value into a `SearchMeta` payload each tool declares as `output.presentationMeta`; `presentGrepResult`/`presentGlobResult` read `result.meta` back through `searchViewFromMeta`. They consume the SAME retained result the model-facing render consumes — `retainGrepMatches`/`retainGlobPaths` in `search-core.ts` run the inline cap and per-line preview budget ONCE, and both the render and the projection take that outcome — so text and card never disagree about which results survived, and there is no second retention pass. `total` is every result the search found (before capping); `truncated` is set when the cap dropped results. This is the truncation-honesty point: the model saw a capped inline result plus a spill footer, so the card must not present the retained page as the complete result — a UI reads `truncated`/`total` to show a capped indicator rather than claiming completeness the model never had.
+
+**The meta has its own byte budget.** The inline cap bounds the item COUNT, but the retained matches of a broad search (hundreds of long lines) can still serialize to hundreds of kilobytes, and `meta` is persisted with the session log and re-sent on every request. A deployment's final output budget (`dsh-spill-policy`, `maxInlineBytes`) only shrinks a result's `content` — `PostToolDecision` has no `meta` channel — so the projection owns keeping `meta` bounded. `capMetaBytes` drops trailing file groups / paths until the serialized meta fits `searchMetaMaxBytes` (config, default 64 KiB) and marks the result `truncated`. A single item too large to fit on its own is kept: the invariant is a bounded payload wherever droppable, never an empty card that hides a real result.
+
+`searchViewFromMeta` narrows the opaque `meta` defensively and returns `undefined` on any malformed or absent payload, so a presenter run on an older or hand-edited replayed log falls back to the generic card instead of throwing. It DOES accept a zero-result payload (`files: []` / `paths: []`) as a valid empty card — this is a deliberate departure from the mirrored `diffsFromMeta`, which rejects empty `diffs`, because a zero-match grep is a legitimate result a UI shows as "no matches", not an absent projection. `presentResult` returns `undefined` for a failed result, for absent meta (a nested `run_code` dispatch computes no `presentationMeta`), and for the other tool's meta shape (each presenter narrows to its own `shape`).
+
+The `SearchMeta` member shapes are object-literal `type` aliases, not the `SearchFileMatches`/`SearchLineMatch` interfaces the view exposes, because only a type alias is assignable to the `JsonValue` index signature `presentationMeta` returns; the two are structurally identical, so the projected value still reads back as a `SearchResultView`.
+
+The TUI (`packages/ui/tui/src/components/transcript.ts`) needs no dedicated arm: its result-view switch handles `terminal` and `diff` explicitly, and a `search` view falls through to the same dim generic body, reading the model-facing text from `this.result?.content`. Because the search view carries no `content` of its own and grep/glob returned a generic card before this PR, the TUI output stays byte-identical to the pre-search-card fallback. The web frontend that renders the structured `files`/`paths` shape is a separate later PR; this PR is the backend contract and its two producers.
+
+## Alternatives considered
+
+**A single flat `SearchResultView` interface with optional `files?` and `paths?`.** Rejected: it makes both shape-specific fields optional on every value and lets a malformed view carry both or neither. The `shape` discriminant keeps each variant's fields required and lets a consumer switch exhaustively.
+
+**Reuse `kind` as the shape discriminant.** Rejected: `kind` already means `ToolCallKind` (the icon category, whose values include `'search'`) on the call view in the same module. A second `kind` with a different meaning on the result view collides for any bridge holding both.
+
+**Attach the model-facing text as the view's `content`.** Rejected: a no-op for every current consumer and a second serialization of the whole search text into the persisted view. The view is the structured shape; text fallback reads the raw result content.
+
+**A meta channel on `PostToolDecision` so `dsh-spill-policy` bounds `meta` like it bounds `content`.** Rejected for this PR: it changes the core tool decision contract and the spill-policy plugin for one tool's payload. The projection bounding its own `meta` at a config byte cap is self-contained and keeps the seam unchanged.
+
+**A call-time `SearchCallView` mirroring the terminal card's both-sides symmetry.** Rejected: a search call has no matches or paths before `execute`, so the view would carry only the title the `GenericCallView` already carries.
+
+## Consequences
+
+`grep` and `glob` now compute `presentationMeta` on every non-nested successful call, a bounded projection over the already-retained matches or paths — the same retention outcome the render consumes, so there is no second retention pass and no doubled search text on the wire. The serialized meta is bounded by `searchMetaMaxBytes`, so a broad search no longer persists an unbounded structured copy into the session log.
+
+A UI without a search card renders the raw `tool/result` content, so no consumer regresses, and the TUI stays byte-identical. The web consumer that renders the structured shape reads `truncated`/`total` and the per-file groups; because the view carries only the retained, byte-bounded page, a UI wanting the complete result follows the spill locator in the model-facing text, exactly as the model does.
+
+## Testing
+
+`packages/fs/tool-fs-search/tests/presentation.spec.ts` pins the pure layer: `groupMatchesByFile`'s first-seen file order; `grepSearchMeta`/`globSearchMeta` projection over a shared retention outcome with `total` reporting the pre-cap count and `truncated` carried through; the per-line preview budget the retention pass applied; the serialized-meta byte cap dropping trailing groups/paths while keeping a single oversized item; and `searchViewFromMeta`'s narrowing of both good shapes, the zero-result empty card, and every malformed case (non-object/array meta, missing or mistyped `truncated`/`total`, unknown `shape`, malformed `files` entries, non-string `paths`). `packages/fs/tool-fs-search/tests/tools.spec.ts` pins the wiring through the real tool registry: a capped `grep`/`glob` execute produces the `SearchMeta` on `result.meta` and `presentResult` builds the search view (no `content`), a nested `run_code` dispatch computes no meta so `presentResult` falls back, and a failed or cross-shape or malformed result falls back to the generic card. Per-file 100% coverage holds over the search package `src`.

+# Agent Note：搜索渲染意图 —— grep 与 glob 产出结构化搜索卡片
+
+Status: implemented
+
+[English](2026-07-30-search-render-card.md) | 中文
+
+## 问题
+
+`grep` 与 `glob` 返回结构化的 canonical 值 —— `grep` 是扁平的 `{ matches: [{ path, lineNumber, line }] }`，`glob` 是 `{ paths: string[] }` —— 但每个 UI 只见过它们面向模型的渲染文本：`grep` 把匹配按文件头分组、每行 `Line N:`，`glob` 打印换行连接的路径列表，两者在内联上限（`grepMaxMatches`，默认 250；`globMaxResults`，默认 100）把后续结果落到 spill 文件时都追加一个 spill 脚注。想把搜索结果渲染成可展开的按文件匹配组、或可选择的路径列表的 web 前端，只能去重新解析那段文本。两个工具都已声明调用时的[渲染意图](../architecture/2026-07-02-tool-render-intent-union.md)（`GenericCallView`，`kind: 'search'`），但没有结果时视图，所以已完成的调用回退到渲染原始文本的 generic 卡片。
+
+结构化 canonical 值不跨线传输：只有面向模型的渲染文本、以及当工具声明了 `output.presentationMeta` 时的一份 JSON 元数据，会经 `tool/result` 事件到达客户端（[canonical-output 契约](../architecture/2026-07-20-canonical-tool-output-contract.md)）。因此携带结构化数据的结果时视图必须把数据投影进 `presentationMeta`，再在 `presentResult` 里读回 —— 与 `write`/`edit` 的 diff 卡片走同一条路。
+
+## 决定
+
+`packages/core/tools/src/presentation.ts` 把 `card: 'search'` 作为 `SearchResultView` 加入 `ToolResultView` 联合，这是一个以 `shape` 判别的视图，表达两个工具的形状：`SearchMatchesResultView`（`shape: 'matches'`）以 `files: { path, matches: { lineNumber, line }[] }[]` 承载 `grep` 按文件分组的匹配，`SearchPathsResultView`（`shape: 'paths'`）承载 `glob` 的扁平 `paths: string[]`。两者都带 `truncated: boolean` 与 `total: number`。
+
+判别子是 `shape` 而非 `kind`，是刻意为之：同一个 presentation 模块已经给 `GenericCallView` 一个 `kind: ToolCallKind` 字段，其取值恰好包含 `'search'`（图标类别）。持有 `ToolCallView | ToolResultView` 的桥接层会看到两个含义不同的 `kind` 字段；结果变体用 `shape` 把两者分开。
+
+用一个带两种形状的视图而非两张卡片，因为两个工具是同一个视觉对象 —— 一个搜索结果 —— web 消费方先在一个 `card` 值上分支，再在 `shape` 上分支决定行布局。判别式 `shape` 让每个变体的字段保持非可选（matches 视图总有 `files`，paths 视图总有 `paths`），而不是一个所有形状相关字段都可选的单一接口。
+
+该视图**不**携带结果文本。早期版本曾把面向模型的 `result.content` 附到视图上；那对每个消费方都是 no-op（TUI 本就回退到 `result.content`，web 回退读原始 `tool/result` 内容），却把整段搜索文本又序列化进持久化视图一遍。视图只承载结构化形状；无 search 卡片的 UI 回退到原始 `tool/result` 内容。
+
+卡片标签只在结果时存在。搜索调用保持为 `GenericCallView`（`kind: 'search'`）：pending 状态没有匹配或路径可展示，所以 `SearchCallView` 能携带的东西不会比 generic 标题更多。这是与 terminal 卡片的不对称之处 —— terminal 的调用视图携带执行前就存在的命令、cwd、description；搜索的结构化内容只在 `execute` 之后才存在。
+
+`packages/fs/tool-fs-search/src/presentation.ts` 拥有投影与收窄。`grepSearchMeta`/`globSearchMeta` 把 canonical 值投影为每个工具声明为 `output.presentationMeta` 的 `SearchMeta` 载荷；`presentGrepResult`/`presentGlobResult` 经 `searchViewFromMeta` 把 `result.meta` 读回。它们消费与面向模型渲染相同的已保留结果 —— `search-core.ts` 里的 `retainGrepMatches`/`retainGlobPaths` 只跑一次内联上限与每行预览预算，render 与投影都取这份产出 —— 所以文本与卡片对哪些结果幸存永不分歧，也没有第二次保留计算。`total` 是搜索找到的全部结果（截断前）；`truncated` 在上限丢弃了结果时置位。这是截断诚实点：模型看到的是被截断的内联结果加一个 spill 脚注，所以卡片不能把保留页当作完整结果 —— UI 读 `truncated`/`total` 显示截断指示，而非宣称模型从未有过的完整性。
+
+**meta 有自己的字节预算。** 内联上限约束的是条目数，但一次宽泛搜索保留下来的匹配（数百条长行）仍可序列化到数百 KB，而 `meta` 会随会话日志持久化并在每次请求时重发。部署的最终输出预算（`dsh-spill-policy` 的 `maxInlineBytes`）只缩减结果的 `content` —— `PostToolDecision` 没有 `meta` 通道 —— 所以投影自己负责把 `meta` 约束住。`capMetaBytes` 丢弃末尾的文件组／路径，直到序列化 meta 装进 `searchMetaMaxBytes`（配置，默认 64 KiB），并把结果标记 `truncated`。单个大到自身都装不下的条目会被保留：不变量是可丢弃处一律有界，绝不产出隐藏了真实结果的空卡片。
+
+`searchViewFromMeta` 防御性地收窄不透明的 `meta`，对任何畸形或缺失载荷返回 `undefined`，使在较旧或手工编辑的回放日志上运行的 presenter 回退到 generic 卡片而非抛错。它确实接受零结果载荷（`files: []` / `paths: []`）为合法的空卡片 —— 这是与被镜像的 `diffsFromMeta` 的刻意偏离（后者拒绝空 `diffs`），因为零匹配的 grep 是 UI 展示为「no matches」的合法结果，而非缺失的投影。`presentResult` 对失败结果、对缺失 meta（嵌套 `run_code` 分发不计算 `presentationMeta`）、以及对另一工具的 meta 形状（每个 presenter 收窄到自己的 `shape`）返回 `undefined`。
+
+`SearchMeta` 的成员形状是对象字面量 `type` 别名，而非视图暴露的 `SearchFileMatches`/`SearchLineMatch` 接口，因为只有 type 别名可赋给 `presentationMeta` 返回的 `JsonValue` 索引签名；两者结构等价，所以投影值仍读回为 `SearchResultView`。
+
+TUI（`packages/ui/tui/src/components/transcript.ts`）不需要专门分支：它的结果视图 switch 显式处理 `terminal` 与 `diff`，`search` 视图落入同一个变暗的 generic body，从 `this.result?.content` 读取面向模型的文本。因为搜索视图不带自己的 `content`，而本 PR 之前 grep/glob 返回的是 generic 卡片，所以 TUI 输出与无 search 卡片的回退逐字节一致。渲染结构化 `files`/`paths` 形状的 web 前端是另一个后续 PR；本 PR 是后端契约及其两个生产者。
+
+## 考虑过的备选
+
+**一个扁平的 `SearchResultView` 接口，带可选 `files?` 与 `paths?`。** 否决：它让两个形状相关字段在每个值上都可选，并允许畸形视图同时带两者或都不带。`shape` 判别式让每个变体的字段保持必需，并让消费方穷尽分支。
+
+**复用 `kind` 作形状判别子。** 否决：同一模块里调用视图上的 `kind` 已经表示 `ToolCallKind`（图标类别，取值含 `'search'`）。结果视图上再有一个含义不同的 `kind`，对任何同时持有两者的桥接层都会冲突。
+
+**把面向模型的文本作为视图的 `content` 附上。** 否决：对每个当前消费方是 no-op，且把整段搜索文本第二次序列化进持久化视图。视图是结构化形状；文本回退读原始结果内容。
+
+**在 `PostToolDecision` 上加 meta 通道，让 `dsh-spill-policy` 像约束 `content` 那样约束 `meta`。** 本 PR 否决：它为一个工具的载荷改动核心工具决策契约与 spill-policy 插件。投影在配置字节上限处约束自己的 `meta` 是自包含的，且保持 seam 不变。
+
+**镜像 terminal 卡片双侧对称的调用时 `SearchCallView`。** 否决：搜索调用在 `execute` 前没有匹配或路径，视图只会携带 `GenericCallView` 已有的标题。
+
+## 后果
+
+`grep` 与 `glob` 现在在每次非嵌套的成功调用上计算 `presentationMeta`，这是对已保留匹配或路径的一次有界投影 —— 与 render 消费的是同一份保留产出，所以没有第二次保留计算，线上也没有翻倍的搜索文本。序列化 meta 受 `searchMetaMaxBytes` 约束，所以宽泛搜索不再把无界的结构化副本持久化进会话日志。
+
+无 search 卡片的 UI 渲染原始 `tool/result` 内容，所以没有消费方退化，TUI 也逐字节一致。渲染结构化形状的 web 消费方读 `truncated`/`total` 与按文件分组；因为视图只携带保留的、字节有界的页，想要完整结果的 UI 跟随面向模型文本里的 spill 定位符，与模型的做法完全一致。
+
+## 测试
+
+`packages/fs/tool-fs-search/tests/presentation.spec.ts` 钉住纯层：`groupMatchesByFile` 的首见文件顺序；`grepSearchMeta`/`globSearchMeta` 在共享保留产出上的投影，`total` 报告截断前计数、`truncated` 被带过；保留过程施加的每行预览预算；序列化 meta 字节上限丢弃末尾组／路径同时保留单个超大条目；以及 `searchViewFromMeta` 对两种良好形状、零结果空卡片、以及每种畸形情形（非对象／数组 meta、缺失或误型的 `truncated`/`total`、未知 `shape`、畸形 `files` 条目、非字符串 `paths`）的收窄。`packages/fs/tool-fs-search/tests/tools.spec.ts` 钉住经真实工具注册表的接线：被截断的 `grep`/`glob` execute 在 `result.meta` 上产出 `SearchMeta`，`presentResult` 构建搜索视图（无 `content`），嵌套 `run_code` 分发不计算 meta 故 `presentResult` 回退，失败或跨形状或畸形结果回退到 generic 卡片。搜索包 `src` 上保持 per-file 100% 覆盖。

+# Agent Note: Versioned GUI welcome onboarding
+
+Status: implemented
+
+English | [中文](2026-07-30-versioned-gui-welcome-onboarding.zh.md)
+
+## Problem
+
+The GUI's credential onboarding begins with a DeepSeek-specific readiness check, but the internal-test notice applies to every user and must precede provider setup even when a credential is already configured. Treating both as independent overlays permits simultaneous dialogs, while a process-local dismissal cannot distinguish a completed notice from a window closed before acknowledgement or intentionally present revised copy once.
+
+## Decision
+
+**The Settings shell coordinates ordered steps.** `settings.onboarding` remains a root-scoped list, but `ui-settings` projects its entry ids and order into one coordinator and mounts only the first incomplete step. The active registrant receives `complete()` and `openSection(id)`; no later step mounts until ownership transfers. The product welcome registers at order `-100`, while `ui-models` retains only the conditional DeepSeek readiness and credential-routing step at order `0`.
+
+**Ownerless product onboarding belongs to `ui-settings-general`.** `src/onboarding-copy.ts` is the single editable source for the complete Chinese notice, its faithful English counterpart, the Continue labels, and `WELCOME_NOTICE_VERSION`. Runtime locale dictionaries derive their welcome values from that file, and tests import the same owner instead of repeating paragraph text. The notice is browser UI only: it creates no Session event and contributes no model-visible content.
+
+**Acknowledgement is durable per Harness profile.** The Host half registers a `ui-onboarding` section in the user-settings seam, stored under the active `$DSH_HOME/settings.yaml`. The browser shows the notice unless `welcomeNoticeVersion` equals the owner constant exactly. Continue applies one path mutation with the current version and calls `complete()` only after the Host commits it; a failed write leaves the notice open, and closing the page or process writes nothing. Bumping the constant intentionally makes every profile acknowledge the revised copy once.
+
+**Concurrent views converge without stale replacement.** The acknowledgement write omits `expectedRevision` deliberately: every tab writes the same version to one path, so the operation is idempotent and preserves sibling fields instead of rebuilding the section. `settings/document-updated` becomes `host/settings-changed`; an already mounted tab refetches and advances when another tab or an external editor commits the current version. The API proxy exposes this one product namespace through a closed allowlist beside configurable-provider namespaces, without treating its changes as model-catalog invalidations.
+
+**Onboarding temporarily owns the viewport as one continuous stage.** A solid product surface replaces the complete application view through a body-level portal and marks the underlying app root inert; the exact required mask remains mounted behind that surface with `position:absolute`, zero left/right/bottom offsets, `top:80px`, `rgba(0, 0, 0, 0.24)`, and `backdrop-filter: blur(2px)`. Welcome and conditional credential setup render as successive pages in this stage instead of independent modals. Both pages reuse the Web UI's black `BrandWordmark`. The welcome page preserves the four authored paragraphs verbatim under the `内测声明` title; every paragraph uses one 16/28 body scale, and only the requested action clause inside the final paragraph receives a subtle 500 weight. A short staggered opacity/vertical entrance supplies pacing without blocking interaction and disappears under reduced motion. The title receives initial focus, Continue is the sole button, and no close, Escape, or mask-click path exists.
+
+## Alternatives considered
+
+**Browser local storage** — rejected because acknowledgement would follow one browser profile rather than `$DSH_HOME`; a fresh Harness profile could incorrectly inherit a prior acknowledgement, and external profile edits would have no authoritative update stream.
+
+**A second independent modal in `ui-settings-general`** — rejected because list registrants would still stack whenever welcome and credential readiness were both true. Ordered ownership belongs to the shell that declares and renders the list.
+
+**Persisting on render or window close** — rejected because observation is not acknowledgement and close delivery is unreliable. Only the explicit Continue commit may suppress the next launch.
+
+**A generic public settings-exposure flag** — rejected because one product namespace does not justify widening every settings registrant's public configuration surface. The gateway keeps an explicit closed allowlist.
+
+## Consequences
+
+A fresh profile always sees the welcome notice before provider-specific onboarding; an already configured credential skips only the later DeepSeek step. Reloading after Continue stays past the acknowledged version, changing the owner version presents it again, and closing before Continue leaves the next launch unchanged. Focused store and React tests pin exact-version comparison, write failure, sole-action behavior, no-dismiss paths, coordinator ordering, conditional DeepSeek transfer, and HMR cleanup. The real Chromium scenario boots the shipped Web composition with an isolated harness home, verifies the exact mask geometry and computed styles, reloads before and after acknowledgement, continues into missing-credential setup, confirms an acknowledged-version mismatch returns while the credential is configured, and checks the browser console.

+# Agent Note: 版本化 GUI 欢迎引导
+
+Status: implemented
+
+[English](2026-07-30-versioned-gui-welcome-onboarding.md) | 中文
+
+## 问题
+
+GUI 的凭据引导从 DeepSeek 专用的就绪状态检查开始，但内部测试通知适用于每位用户，即使凭据已经配置，也必须先于提供方设置显示。若把两者作为独立浮层处理，多个对话框可能同时出现；仅存于进程内的关闭标记既无法区分通知已完成确认还是窗口在确认前已关闭，也无法在文案有意修订后重新显示一次通知。
+
+## 决策
+
+**设置外壳协调有序步骤。** `settings.onboarding` 仍是根作用域 list，但 `ui-settings` 会把其中各条目的 id 和顺序投影到一个协调器中，并且只挂载第一个未完成的步骤。当前注册方会收到 `complete()` 和 `openSection(id)`；所有权转移前，不会挂载后续步骤。产品欢迎步骤的顺序为 `-100`，`ui-models` 则只保留顺序为 `0` 的 DeepSeek 条件式就绪状态与凭据跳转步骤。
+
+**不属于单一功能的产品引导由 `ui-settings-general` 持有。** `src/onboarding-copy.ts` 是完整中文通知、忠实英文对侧文案、两种语言的「继续」按钮文案和 `WELCOME_NOTICE_VERSION` 的唯一可编辑来源。运行时 locale 字典从该文件派生欢迎文案，测试也导入同一个所有者，而不重复段落文本。该通知只存在于浏览器 UI：它不会创建会话事件，也不会贡献任何模型可见内容。
+
+**确认状态按 Harness profile 持久化。** 宿主端在 user-settings seam 中注册 `ui-onboarding` 分节，并存入当前 `$DSH_HOME/settings.yaml`。除非 `welcomeNoticeVersion` 与文案所有者文件中的常量精确相等，否则浏览器会显示通知。「继续」会以当前版本执行一次路径变更，并且仅在宿主端提交成功后调用 `complete()`；写入失败时通知保持打开，关闭页面或进程则不会写入任何内容。提升该常量会有意要求每个 profile 对修订后的文案重新确认一次。
+
+**并发视图无需陈旧的整体替换即可收敛。** 确认写入有意省略 `expectedRevision`：每个标签页都向同一路径写入相同版本，因此该操作是幂等的，并会保留同级字段，而不是重建整个分节。`settings/document-updated` 会转为 `host/settings-changed`；另一个标签页或外部编辑器提交当前版本后，已挂载的标签页会重新拉取状态并推进。API 网关在可配置提供方 namespace 之外，通过封闭的允许列表暴露这一个产品 namespace，同时不会把它的变更视为模型目录失效事件。
+
+**引导流程会暂时接管视口，形成一个连续阶段。** 纯色产品界面通过挂载到 `body` 的 portal 取代完整的应用视图，并将底层应用根节点标记为 inert；严格符合要求的遮罩仍挂载在该界面后方，并保留 `position:absolute`、left/right/bottom 偏移量为零、`top:80px`、`rgba(0, 0, 0, 0.24)` 和 `backdrop-filter: blur(2px)`。欢迎页和按条件显示的凭据设置页在这一阶段中依次呈现，而不是各自作为独立的模态窗口。两个页面都复用 Web UI 的黑色 `BrandWordmark`。欢迎页在 `内测声明` 标题下逐字保留既定的四段文案；所有段落统一采用 16/28 的正文字号与行高，只有最后一段中指定的行动语句使用较为克制的 500 字重。短暂的错落式透明度与纵向位移动画营造出舒缓节奏，但不会阻碍交互，并会在用户启用减少动态效果时禁用。初始焦点落在标题上，「继续」是唯一按钮，且不存在关闭、Escape 或点击遮罩的退出路径。
+
+## 曾考虑的替代方案
+
+**浏览器本地存储**：不予采用，因为确认状态会跟随某个浏览器 profile，而不是 `$DSH_HOME`；全新的 Harness profile 可能错误继承此前的确认状态，外部 profile 编辑也没有权威更新流。
+
+**在 `ui-settings-general` 中再增加一个独立模态窗口**：不予采用，因为欢迎通知和凭据就绪状态同时为真时，list 注册方仍会堆叠。声明并渲染该 list 的外壳应当持有有序所有权。
+
+**在渲染或窗口关闭时持久化**：不予采用，因为看见通知不等于确认，窗口关闭事件也无法可靠送达。只有显式提交「继续」才能阻止通知在下次启动时再次显示。
+
+**通用的公开设置暴露标志**：不予采用，因为一个产品 namespace 不足以证明应当扩大每个 settings 注册方的公开配置面。网关保留显式的封闭允许列表。
+

+# Agent Note: Default Web search in the Web/headless composition
+
+Status: implemented
+
+English | [中文](2026-07-31-web-default-search.zh.md)
+
+## Problem
+
+The harness had a complete Web capability family—provider registry, DeepSeek/Exa/Perplexity search providers, local fetch, stable model tools, and structured result presentation—but the shipped `dsh web` composition mounted none of it. The model could not discover current information unless a deployment supplied a custom overlay. Merely mounting the existing DeepSeek provider would not complete the WebUI path: the Models page stores `DEEPSEEK_API_KEY` through `ctx.credentials`, while the search provider froze only the process environment at plugin load, so a key entered or rotated in the running UI would not reach search.
+
+## Decision
+
+`apps/cli/config/web.cordis.yml` explicitly mounts `dsh-web` with `searchProvider: deepseek-official`, `dsh-web-search-deepseek`, and `dsh-tool-web` with `fetch: false`. It does not mount `dsh-web-fetch-local` or select a fetch provider. The shared overlay makes only `web_search` a default for browser and headless sessions; the TUI composition remains unchanged. The explicit search provider id keeps selection independent of registration order and leaves personal or `--config` overlays able to replace or disable the rows.
+
+DeepSeek search uses the same `DEEPSEEK_API_KEY` credential reference as the official conversation adapter. The provider resolves that reference inside every search through the optional `ctx.credentials` service; only a composition without the seam falls back to the launching process environment, and a non-empty literal `apiKey` remains the programmatic last resort. A stored or rotated Web Models key therefore reaches the next search without restarting or retaining the value on the provider. Because `WebSearchProvider.available()` is synchronous, it treats an installed resolver as locally usable and missing dynamic credentials fail the operation with the provider-specific `WEB_PROVIDER_CREDENTIAL_MISSING` code while the stable tool schema stays registered.
+
+Search keeps its endpoint distinct from chat completions: `DEEPSEEK_SEARCH_BASE_URL` overrides the Anthropic-compatible base, while `DEEPSEEK_BASE_URL` continues to configure conversation requests. Each `web_search` performs an auxiliary DeepSeek Messages call with the native search server tool. Immediately before dispatch, the provider appends a log-only `web/deepseek-search-llm-request` event to the initiating Agent session with the resolved endpoint, API version, and exact secret-free JSON body. Credential preflight remains provider-local and races caller cancellation; neither concern expands the generic Web or credentials seams.
+
+The default mount does not create a Web-specific permission policy. `web_search` executes outside the bash/filesystem sandbox and approval presets, following `dsh-tool-web`'s existing contract. It does not mount `web_fetch` or a local fetch provider, so the default does not grant model-selected arbitrary URL retrieval. The shipped deployment already defaults to `danger-full-access`; a future restricted-network product stance must add a `tools/pre-execute` policy or capability-specific network confinement rather than implying that filesystem access mode governs Web calls.
+
+## Alternatives considered
+
+**Mount only `dsh-tool-web`.** Rejected because stable schemas without registered providers would make every default call fail; enablement and backend availability are deliberately separate, but a shipped default must supply its intended implementations.
+
+**Read `$DSH_HOME/.env` from `cordis.yml` or hoist it into `process.env`.** Rejected because the credential provider owns that document, environment values are read-only overrides, and hoisting would make stored keys unrotatable while bypassing the audited secret boundary.
+
+**Freeze `process.env.DEEPSEEK_API_KEY` at provider load.** Rejected because the Web Models page writes through `ctx.credentials`; the product's documented first-run path must make the next operation work without a restart.
+
+**Mount Web tools in `base.cordis.yml`.** Rejected because that would also change the TUI deployment. The browser and headless entries already share `web.cordis.yml`; they gain the capability together while TUI remains an explicit later decision.
+
+**Enable search and fetch together.** Rejected because default `web_fetch` would allow model-selected anonymous outbound HTTP(S) retrieval to arbitrary URLs. Search covers discovery; deployments that accept broader retrieval can opt into `dsh-web-fetch-local` and set `dsh-tool-web`'s `fetch` option to `true` in their overlay.
+
+## Consequences
+
+Web/headless model requests carry only the `web_search` schema and search-only prompt guidance in native mode; Code Mode exposes the same search capability beneath `run_code`. The prompt tells the model to use returned snippets and never advertises the disabled `web_fetch` tool. Search adds a complete auxiliary model call and may use the native server tool multiple times; its exact secret-free request remains reconstructable from the initiating session log. The default offers search-result snippets and source metadata but no arbitrary page retrieval; deployments that need full-page fetch must opt in. The Web snapshot lane boots the shipped tree, drives a replayed `web_search` call through the real DeepSeek provider against a local Messages fixture, asserts the durable auxiliary request and structured result, and pins the settled browser presentation. The real-composition smoke test pins the absence of `web_fetch`; provider tests pin missing, stored, and rotated credential behavior plus literal and ambient compatibility.

+# Agent Note: Web／无头组合中的默认 Web 搜索
+
+Status: implemented
+
+[English](2026-07-31-web-default-search.md) | 中文
+
+## 问题
+
+该 harness 已具备完整的 Web 能力体系：提供方注册表、DeepSeek、Exa 和 Perplexity 搜索提供方、本地抓取、稳定的面向模型工具，以及结构化结果呈现，但已交付的 `dsh web` 组合没有挂载其中任何一项。除非部署提供自定义覆盖层，否则模型无法发现最新信息。仅挂载现有 DeepSeek 提供方仍无法打通 WebUI 链路：Models 页面通过 `ctx.credentials` 存储 `DEEPSEEK_API_KEY`，而搜索提供方只会在插件加载时固定读取进程环境，因此在运行中的 UI 输入或轮换的密钥无法用于搜索。
+
+## 决策
+
+`apps/cli/config/web.cordis.yml` 明确挂载 `dsh-web`，配置 `searchProvider: deepseek-official`，同时挂载 `dsh-web-search-deepseek`，并以 `fetch: false` 挂载 `dsh-tool-web`。它不挂载 `dsh-web-fetch-local`，也不选择抓取提供方。共享覆盖层只将 `web_search` 设为浏览器与无头会话的默认工具；TUI 组合保持不变。显式搜索提供方 id 使选择不受注册顺序影响，同时个人覆盖层或 `--config` 覆盖层仍可替换或禁用这些配置项。
+
+DeepSeek 搜索使用与官方会话适配器相同的 `DEEPSEEK_API_KEY` 凭据引用。提供方在每次搜索内部通过可选的 `ctx.credentials` 服务解析该引用；只有未挂载该 seam 的组合才会回退到启动进程的环境变量，非空的 `apiKey` 字面值仍作为程序化配置的最后兜底。因此，由 Web 的 Models 页存储或轮换的密钥无需重启即可用于下一次搜索，提供方也无需保留该值。由于 `WebSearchProvider.available()` 是同步方法，它会将已安装解析器视为本地可用；若动态凭据缺失，操作会以提供方专属错误码 `WEB_PROVIDER_CREDENTIAL_MISSING` 失败，而稳定的工具 schema 仍保持注册。
+
+搜索端点与 chat completions 保持独立：`DEEPSEEK_SEARCH_BASE_URL` 覆盖 Anthropic 兼容基址，`DEEPSEEK_BASE_URL` 则继续配置会话请求。每次 `web_search` 都会发起一次辅助 DeepSeek Messages 调用，并携带原生搜索服务器工具。发出请求前一刻，提供方会向发起请求的 agent（智能体）会话追加仅用于日志的 LLM（大语言模型）请求事件 `web/deepseek-search-llm-request`，其中包含已解析端点、API 版本，以及不含密钥的精确 JSON 请求体。凭据预检仍留在提供方内部，并与调用方取消存在竞态；这两项关注点都不会扩展通用 Web seam 或凭据 seam。
+
+默认挂载不会创建 Web 专用权限策略。`web_search` 在 bash／文件系统沙箱及审批预设之外执行，并遵循 `dsh-tool-web` 的现有契约。组合不挂载 `web_fetch` 或本地抓取提供方，因此默认配置不会允许模型自行选择任意 URL 进行抓取。已交付部署的默认值本就是 `danger-full-access`；未来如果产品采取受限网络策略，必须添加 `tools/pre-execute` 策略或按能力限制网络访问，而不能暗示文件系统访问模式会管辖 Web 调用。
+
+## 考虑过的替代方案
+
+**仅挂载 `dsh-tool-web`。** 不予采纳：稳定的 schema 如果没有已注册提供方，每次默认调用都会失败。启用状态与后端可用性刻意分离，但已交付的默认配置必须提供其预期实现。
+
+**从 `cordis.yml` 读取 `$DSH_HOME/.env`，或将其提升到 `process.env`。** 不予采纳：凭据提供方拥有该文件，环境变量值是只读覆盖；提升后存储的密钥将无法轮换，还会绕过经审计的密钥边界。
+
+**在提供方加载时固定读取 `process.env.DEEPSEEK_API_KEY`。** 不予采纳：Web Models 页面通过 `ctx.credentials` 写入密钥；产品文档规定的首次运行路径必须保证下一次操作无需重启即可生效。
+
+**在 `base.cordis.yml` 中挂载 Web 工具。** 不予采纳：这也会改变 TUI 部署。浏览器与无头入口已经共享 `web.cordis.yml`；两者会一同获得该能力，是否为 TUI 启用则仍留作后续显式决策。
+
+**同时启用搜索和抓取。** 不予采纳：默认启用 `web_fetch` 会允许模型自行选择任意 URL，执行匿名出站 HTTP(S) 抓取。搜索负责发现信息；接受更广泛抓取范围的部署可以在覆盖层中选择启用 `dsh-web-fetch-local`，并将 `dsh-tool-web` 的 `fetch` 选项设为 `true`。
+
+## 后果
+
+Web／无头模型请求在原生模式下只会携带 `web_search` schema，以及仅用于搜索的提示词指引；Code Mode 通过 `run_code` 公开相同的搜索能力。该提示词要求模型使用返回的 snippet，且绝不会向模型提及已禁用的 `web_fetch` 工具。搜索会增加一次完整的辅助模型调用，并可能多次使用原生服务器工具；发起会话的日志仍可精确重建其不含密钥的请求。默认配置会提供搜索结果 snippet 与来源元数据，但不支持任意页面抓取；需要抓取完整页面的部署必须自行选择启用抓取。Web 快照通道会启动已交付配置树，使用本地 Messages fixture（测试前置数据），经由真实 DeepSeek 提供方驱动一次回放的 `web_search` 调用，断言持久化的辅助请求与结构化结果，并固定最终浏览器呈现。真实组合冒烟测试固定了不提供 `web_fetch` 这一事实；提供方测试固定缺失、已存储及已轮换凭据的行为，以及字面值与环境变量的兼容性。

+ * model-facing render consumes ({@link module:@deepseek-ai/dsh-tool-fs-search/search-core}
+ * `retainGrepMatches`/`retainGlobPaths`), so text and card agree about which
+ * results survived the inline cap, and reports `total` (every result found) and
+ * `truncated`, so a UI never presents a capped result as complete.
+ *
+ * A second, independent cap bounds the JSON `meta` itself: the retained matches
+ * of a broad search (hundreds of long lines) can still serialize to hundreds of
+ * kilobytes, and `meta` is persisted with the session log and re-sent on every
+ * request. {@link capMetaBytes} drops trailing groups/paths until the serialized
+ * `meta` fits `maxMetaBytes` and marks the result `truncated`; a deployment's

Subject: [PATCH 216/557] test(web-cards): update card specs and snapshots for
 collapsed ToolRow

Rewrite the read/search/web/diff card spec suites for the collapsed-by-default
ToolRow composition: each row now needs the conversation `t`, and the card is
absent from the DOM until the row's [data-expandable] toggle is clicked. Refresh
the built-boot and search-card assembled snapshots (they expand the row before
shaping the card) and the code-mode-round golden. Fix a fixture turn-number
collision the 985/986 merge introduced (grep reused turn 67, already the
multi-hunk edit's, so both shared one callId) by renumbering search/web/todo to
68-72. Document the refactor's behavior in the ui-conversation README (both
languages) and add the Agent Note.

+# Agent Note: Card tool rows collapse through one ToolRow
+
+Status: implemented
+
+English | [中文](2026-07-31-web-cards-toolrow.zh.md)
+
+## Problem
+
+The Web client grew five card render intents over successive PRs — terminal, diff, read, search, web — each landing as a keyed toolview registrant under `packages/client/ui-conversation/src/client/toolviews/`. They diverged in two ways the earlier PRs each acknowledged but deferred:
+
+- **Chrome duplication.** `read-row`, `search-row`, `web-row`, and `file-mutation-row` each hand-drew the summary row (leading state slot, visually-hidden status, title, separator dot, path-link/summary) as their own `
` with a private `.module.css`, instead of composing the shared `ToolRow`. `read-row` carried a `jscpd:ignore` marker naming the duplication and pointing at "a separate change tracked for all rows at once" — this change.
+- **Resident vs. collapsed.** Those four rows kept their card (`ReadBlock`/`SearchBlock`/`WebBlock`/`DiffBlock`) resident below the summary — always expanded — while the terminal card (via `GenericToolCard`/`BashRow`) and every text row started collapsed behind ToolRow's whole-row expand. A conversation with several read/search/web/edit calls became a wall of always-open cards, defeating the summary-surface purpose of the message flow.
+
+## Decision
+
+`ToolRow` owns every card kind, and every keyed card row composes it. ToolRow already took `terminal` and `diff` card material; it now also takes `read`, `search`, and `web`, rendering whichever is present in its collapsed-by-default expanded body through the matching primitive (capped at the chat `CHAT_*` bounds). A call carries at most one card kind, so the props are mutually exclusive and the body picks the first present.
+
+The four keyed rows — `ReadRow`, `SearchRow`, `WebRow`, `FileMutationRow` — drop their hand-drawn chrome and private CSS and become thin `ToolRow` compositions, exactly like `AskQuestionRow`: derive the card model, pass it as the matching ToolRow prop, forward `filePath`/`onOpenFile` for the file tools and `output`/`errorSummary` for the cardless failure paths. Each row is now `ToolRowProps & PropsLocale<'conversation'>` and registers with `locale: NS`, because ToolRow needs the conversation `t` for its terminal/code body copy. `GenericToolCard` (the render-site fallback) does the same for read/search/web, so a card-declaring tool without its own keyed row collapses identically.
+
+The `DetailsPanel` Output section is unchanged: the panel is the single-call reading surface, so it renders each card resident at the primitive's full height, and a capped search keeps its recovery footer there.
+
+## Consequences
+
+- One expand interaction across all tool rows: collapsed one-line summary, whole row toggles the card. The card is not in the DOM until expanded (`DisclosureRow` renders `children` only when open), so tests assert absent-then-present around a `[data-expandable]` click.
+- Deleted: `read-row.module.css`, `search-row.module.css`, `web-row.module.css`, `file-mutation-row.module.css`, `GenericToolCard.module.css`. The rows carry no CSS of their own; ToolRow's module owns the chrome and the card-body indentation.
+- The cardless failure paths (an errored mutation, an errored/nested/legacy search) no longer draw their own `.failure`/recovery `
`; they ride ToolRow's `output` (Output section) and `errorSummary` (collapsed summary first line), which already flatten the result text with the `error.name: error.code` fallback.
+- `bash-sample` keeps its own local expand chrome deliberately (the third-party-posture exemplar that never imports the chat domain); it was already collapsed, so its behavior is unchanged.
+
+## Alternatives considered
+
+- **Keep the rows resident, only unify chrome.** Rejected: the user's requirement is default-collapsed, and resident cards are what made the flow unscannable.
+- **A shared `CardRow` wrapper between the rows and ToolRow.** Rejected: ToolRow already is that wrapper once it takes every card kind; a second layer would be the premature extraction the package rules warn against.

+# Agent Note：卡片工具行通过同一个 ToolRow 折叠
+
+Status: implemented
+
+[English](2026-07-31-web-cards-toolrow.md) | 中文
+
+## 问题
+
+Web 客户端在连续几个 PR 里长出五种卡片渲染意图——terminal、diff、read、search、web，每一种都作为一个键控 toolview 注册项落在 `packages/client/ui-conversation/src/client/toolviews/` 下。它们在两处出现分歧，之前每个 PR 都承认却推迟处理：
+
+- **Chrome 重复。** `read-row`、`search-row`、`web-row`、`file-mutation-row` 各自把摘要行（行首状态槽、视觉隐藏状态、标题、分隔点、路径链接/摘要）手绘成自己的 `
`，配一份私有 `.module.css`，而不是组合共享的 `ToolRow`。`read-row` 带着一个 `jscpd:ignore` 标记，点名这处重复并指向"一处针对所有行一次性处理的独立改动"——就是本次改动。
+- **常驻 vs 折叠。** 那四个行把卡片（`ReadBlock`/`SearchBlock`/`WebBlock`/`DiffBlock`）常驻在摘要下方——始终展开——而终端卡片（经 `GenericToolCard`/`BashRow`）与每个文本行都从折叠状态起步，藏在 ToolRow 的整行展开之后。一个有多个 read/search/web/edit 调用的对话就成了一堵始终打开的卡片墙，违背了消息流作为摘要面的目的。
+
+## 决策
+
+`ToolRow` 拥有每一种卡片，而每个键控卡片行都组合它。ToolRow 原本就接收 `terminal` 与 `diff` 卡片材料；现在还接收 `read`、`search`、`web`，在其默认折叠的展开 body 里用对应原语渲染当前存在的那一种（按 chat 的 `CHAT_*` 上限截断）。一次调用最多携带一种卡片，因此这些 prop 互斥，body 取第一个存在的。
+
+四个键控行——`ReadRow`、`SearchRow`、`WebRow`、`FileMutationRow`——丢掉手绘 chrome 与私有 CSS，成为薄薄的 `ToolRow` 组合，与 `AskQuestionRow` 完全一样：推导卡片模型，作为对应的 ToolRow prop 传入，为文件工具转发 `filePath`/`onOpenFile`，为无卡片的失败路径转发 `output`/`errorSummary`。每个行现在是 `ToolRowProps & PropsLocale<'conversation'>` 并以 `locale: NS` 注册，因为 ToolRow 需要对话的 `t` 来渲染其终端/代码 body 文案。`GenericToolCard`（渲染点兜底）对 read/search/web 做同样的事，所以一个没有自己键控行的卡片声明工具也以同样方式折叠。
+
+`DetailsPanel` 的 Output 区不变：面板是单次调用的阅读面，因此它以原语的完整高度常驻渲染每张卡片，被截断的搜索也把恢复脚注留在那里。
+
+## 后果
+
+- 所有工具行共享一套展开交互：折叠时是单行摘要，整行切换卡片。卡片在展开前不在 DOM 里（`DisclosureRow` 只在打开时渲染 `children`），因此测试围绕一次 `[data-expandable]` 点击断言"先无后有"。
+- 已删除：`read-row.module.css`、`search-row.module.css`、`web-row.module.css`、`file-mutation-row.module.css`、`GenericToolCard.module.css`。这些行不再带自己的 CSS；ToolRow 的 module 拥有 chrome 与卡片 body 的缩进。
+- 无卡片的失败路径（出错的改动，出错/嵌套/旧日志的搜索）不再画自己的 `.failure`/恢复 `
`；它们改走 ToolRow 的 `output`（Output 区）与 `errorSummary`（折叠摘要首行），后者已经用 `error.name: error.code` 兜底压平结果文本。
+- `bash-sample` 有意保留自己本地的展开 chrome（第三方姿态的范例，从不引入 chat 域）；它本来就是折叠的，因此行为不变。
+
+## 考虑过的替代方案
+
+- **保持行常驻，只统一 chrome。** 否决：用户的要求是默认折叠，而常驻卡片正是让流不可扫读的原因。
+- **在行与 ToolRow 之间加一层共享的 `CardRow` 包装。** 否决：ToolRow 一旦接收每一种卡片，它本身就是那层包装；再加一层就是 package 规则警告的过早抽取。

 A tool call declaring the `terminal` render intent renders its command output inline, at both conversation render sites, through ui-primitives' `TerminalBlock`. `contract/terminal-card-model.ts` is the single derivation from the snapshot's `callView`/`resultView` pair, so the sites cannot disagree about a command, its cwd, or its exit status; it yields null — the generic path — for any other card tag, including one this client version does not know. Both sites therefore also show the card's run-state dot, which is the same `StateDot` semantic a tool row's leading icon carries, so a row and its own card always agree about one command's state. A multi-line command gets one prompt row per line, with the dot marking the call once on the first row — the exit status is the whole call's, so a dot per line would claim a per-line outcome bash does not report. The keyed `BashRow` carries the card resident below its summary row; since tool rows are no longer details-panel click targets, the card's copy and expand controls are the row's only interactions. The render-site fallback row keeps the card behind its existing expand control. Rows cap at `CHAT_TERMINAL_MAX_LINES` (8) against the panel's 16, which is what keeps a summary surface bounded — the panel stays the single-call reading surface. Inline output is licensed per render intent — the terminal and web cards, each with its own bound; a generic tool's content remains panel-only ([decision](../../../.agents/notes/implemented/feature/2026-07-28-web-terminal-card.md)).
 
-A tool call declaring the `web` render intent renders its web retrieval inline, at both conversation render sites, through ui-primitives' `WebBlock`. `contract/web-card-model.ts` is the single derivation from the snapshot's `resultView`, mirroring the terminal card, so the sites cannot disagree about what a web call shows; it yields null — the generic path — for a running call, a non-web result view, a generic result view, a `card` tag this client version does not know, or a web card whose `kind` this client version does not know (a newer host's value, which the wire cannot be trusted to be `search` or `fetch`). The keyed `WebRow` registers one component under both `web_search` and `web_fetch`, discriminating on the tool name only for its icon and title; a web-declaring tool without a keyed row lands on the `GenericToolCard` fallback, which grows the same resident card, and the details panel renders it at the primitive's full source allowance and, below the card, the flattened model-visible result content — a fetch body is readable only there, since its card carries only the URL and status. Rows cap at `CHAT_WEB_MAX_SOURCES` (8) against the panel's 16, the same summary-versus-reading split the terminal card draws ([decision](../../../.agents/notes/implemented/feature/2026-07-30-web-result-card-frontend.md)).

The keyed `WebRow` registers one component under both `web_search` and `web_fetch`, discriminating on the tool name only for its icon and title; it composes the shared `ToolRow`, feeding the card as ToolRow's `web` body, so the retrieval is the row's collapsed-by-default expanded card (the same unified expand every card row has). A web-declaring tool without a keyed row lands on the `GenericToolCard` fallback, which routes the card through ToolRow the same way, and the details panel renders it at the primitive's full source allowance and, below the card, the flattened model-visible result content — a fetch body is readable only there, since its card carries only the URL and status.

 The chat flow projects consecutive model-retry nodes across retry turns into one stable, muted status row updated to the latest attempt; every retry event remains in the runtime snapshot and session log. Its frontend countdown anchors the scheduled delay to client receipt, avoiding host/browser clock skew, rounds remaining time up to seconds, and has a one-second floor. The latest unresolved retry uses a left-to-right text shimmer. Subsequent turn facts distinguish an attempt that started from one cancelled during backoff, while the Host running bit only controls the live animation; the row then shows a static completed or cancelled label. Normal policy rows show the finite retry maximum; always policy rows show `∞`. Activating the row reveals the latest exact retry delay and failure message. The client runtime removes each failed step's streaming tail before its retry node arrives, while the status remains visible after a later attempt succeeds.
 
-A `grep`/`glob` call declaring the `search` render intent renders its result inline, at the same render sites, through ui-primitives' `SearchBlock` — grep's matches grouped by file (each a collapsible header of `lineNumber: line` rows), glob's flat path list. `contract/search-card-model.ts` is the single derivation from the snapshot's `resultView`; unlike the terminal card it reads no `callView`, since a search has no matches or paths before `execute`, so a running search shows its summary alone. It yields null — the generic path — for any non-search result view, a `card` or `kind` this client version does not compile, and (because those ride the untrusted wire frame) a known kind whose `files`/`paths` is malformed. The keyed `SearchRow`, registered under both `grep` and `glob` since the derived `kind` decides the shape, carries the card resident below its summary; the render-site fallback keeps it behind the expand control. Both cap at `CHAT_SEARCH_MAX_LINES` (8) against the panel's 16. A capped search drops rows from the card, but the locator to the rest — grep/glob's `Full … stored at …` footer — lives only in the result text, so the derivation surfaces that as a recovery footer below the card when (and only when) the result was truncated; a settled call with no card at all (an errored search, a nested `run_code` sub-dispatch, a legacy generic result) falls back to its flattened result text so nothing is lost behind a bare summary ([decision](../../../.agents/notes/implemented/feature/2026-07-30-web-search-card.md)).

 Tool rows are slots too — the standalone tool ring (`ToolViewRegistry`/`ctx.toolviews`/outlet) is retired. The chat entry declares the keyed `'conversation.chat.toolview'` hole (session scope; the key space is runtime-open); its render site dispatches per row via `entryKey: toolName` with `GenericToolCard` as the call-site `fallback`. The owner payload is the uniform `ToolRowOwnerProps` (`callId`/`toolName`/`block`/`openFile`) and `ToolRowProps` pre-composes it with the session standard kit. A registrant is a plain plugin: `ctx.slots.register({ name: 'conversation.chat.toolview', key: '', inject? }, Row)` with `inject: ['slots', 'conversation']` as the load-order seam (apply mounts ConversationService after the chat registration, so the service being present guarantees the slot is declared); session differentiation happens inside the component (`useSessions` reading `parentId` — the bash sample is the third-party-posture exemplar). Trajectory/waterfall toolview slots share this shape and land with their own render sites (RendersCheck rejects a declaration nobody renders).

Subject: [PATCH 217/557] feat(tui): open the /resume picker immediately with a
 loading state

The selector overlay opens as soon as the command dispatches: the
picker renders a loading placeholder over an undefined candidate set,
owns terminal input from its first frame, answers Enter with a
still-loading error, and cancels on Escape exactly like the loaded
list. The finished scan swaps rows in through setCandidates without
replacing the overlay; a scan failure closes it and keeps the existing
notice.

 The `/resume` selector builds all candidate rows from one `projectSessions` batch; a rejected projection degrades to that row's disabled "Unreadable session" fallback exactly as a failed `readSession` did. `summarizeResumeCandidate` takes the borrowed source and retains only the record and derived scalars. The pre-handoff preflight still reads the single chosen session through `readSession`, keeping full replay validation before the process re-execs; its redundant live-session shortcut was dropped because `readSession` is already live-preferred.
 
+The selector overlay opens synchronously when `/resume` dispatches, before the scan settles: an `undefined` candidate set renders a "Loading sessions…" placeholder, the picker owns terminal input from its first frame (so keystrokes during a long scan reach the search field rather than the editor), Enter reports that sessions are still loading, and Escape cancels exactly as it does on the loaded list. The finished scan swaps rows in through `setCandidates` without replacing the overlay; a queued activation behind a closing predecessor receives an already-scanned set at construction; a scan failure closes the overlay and reports the existing failure notice.

 **Fix only the O(N²) listing inside `SessionCorpus.load()`.** Rejected as the primary fix: the per-candidate full decompress, replay validation, and triple clone dominate on large logs and remain O(total log bytes).

+`/resume` opens a full-viewport keyboard selector instead of a centered dialog. The selector opens as soon as the command runs and takes input focus while the session scan is still pending, showing a loading placeholder until the rows arrive; Escape cancels an in-flight scan the same way it cancels the loaded list. Two scopes cover the same candidate set: the current workspace, which it opens on, and all workspaces, which Tab toggles to. The scope line under the search field names the active scope and the count the other holds, and each row in the all-workspaces scope also reports its own workspace. Toggling clears the search and selection so the highlighted row always belongs to the visible list.
 
 Its focused search field starts immediately after the search glyph and emits pi-tui's cursor marker, so terminal IME composition remains anchored inside the field. Candidates are sorted by last logged activity and searchable by log-backed title or session id, and by workspace label in the all-workspaces scope; each row reports current/live/persisted state, last turn outcome, recent provider/model, and durable goal phase when present. Up/Down and Page Up/Page Down navigate, Enter resumes, Escape clears a non-empty search before a second Escape cancels, and Ctrl+C cancels directly. The current session, a session already live in this runtime, an unreadable log, a session with no recorded workspace to run in, or a session whose logged provider has no current adapter remains visible but disabled; a workspace other than the current one is a scope rather than a disabled reason, because resume enters that directory.

Subject: [PATCH 218/557] feat(tui): /details command sets card visibility and
 reasoning display

/details reports the transcript detail state bare, jumps tool cards to
collapsed|expanded|hidden, and sets or toggles reasoning blocks, sharing
the closure state behind Ctrl+O/Ctrl+R via setToolsVisibility/setReasoning.

Also fixes a replay defect the reasoning rebuild exposed: rebuildTranscript
reused a settled StreamingAssistantComponent for a later assistant/message
of the same step, overwriting the earlier content; the settled check now
lives in renderEvent for both live and replay paths (untrusted-controls
re-recorded with the previously dropped content present).

+# Agent Note: /details command for transcript detail state
+
+Status: implemented
+
+English | [中文](2026-07-30-tui-details-command.zh.md)
+
+## Problem
+
+The TUI's transcript detail state — tool-card visibility (`collapsed`/`expanded`/`hidden`, per the [consolidated TUI presentation](../architecture/2026-07-28-consolidated-tui-presentation.md)) and reasoning-block display — was reachable only through the Ctrl+O cycle and the Ctrl+R toggle. A user who wants a specific mode must cycle through the others, cannot set both dimensions in one action, and has no way to query the current state; a terminal that swallows those control keys has no fallback at all.
+
+## Decision
+
+`dsh-tui` registers `/details` beside its other agent-scoped commands. Bare `/details` reports the current state in one notice. Arguments name target states directly: `collapsed|expanded|hidden` jumps tool cards to that phase, `reasoning on|off` sets reasoning display, bare `reasoning` toggles it, and directives combine in one invocation. An unknown token returns a command error carrying the usage line. The command mutates the same closure state as the shortcuts, refactored so the cycle and toggle are thin wrappers over `setToolsVisibility`/`setReasoning`; the shortcuts and their notices are unchanged.
+
+A combined invocation applies reasoning before visibility because `setReasoning` rebuilds the transcript from session events, which drops non-durable notice components; applying it last would erase the just-appended visibility notice.
+
+The reasoning rebuild exposed a replay defect that this change fixes in `renderEvent`: the live path cleared a settled `StreamingAssistantComponent` before a later `assistant/message` of the same step (so the second message got a fresh component), but `rebuildTranscript` replay reused the settled component and `settle()` overwrote its content, silently dropping the earlier message's text. The settled check now lives in `renderEvent`'s `assistant/message` case — one home for both paths — and the previously wrong `untrusted-controls` snapshot (an empty `Assistant` header where reasoning and text had been dropped) was re-recorded with the content present.
+
+## Alternatives considered
+
+**Cycle on bare `/details`, mirroring Ctrl+O.** Rejected: the command's value over the shortcut is naming an absolute state; a cycling command is the shortcut with more keystrokes, and bare invocation is more useful as a state report.
+
+**Separate `/tools` and `/reasoning` commands.** Rejected: both dimensions are one presentation concern ("how much detail does the transcript show"), and a single command keeps the registry and `/help` list small while allowing one combined invocation.
+
+**Config-key defaults per mode.** Out of scope: `showReasoning` already exists as config; the command is runtime state on top of it, matching the shortcuts.
+
+## Consequences
+
+- A user can jump to any detail mode, set both dimensions at once, and query the state — including on terminals that intercept Ctrl+O/Ctrl+R.
+- The parser accepts order-free tokens, so `/details reasoning expanded` toggles reasoning and expands cards; last directive wins per dimension. This leniency is deliberate and documented in the README.
+- Transcript rebuilds no longer lose assistant messages when a step carries more than one `assistant/message` event; the `details-command` snapshot pins the command surface and the fixed replay together.

+# Agent Note: 用于 transcript 细节状态的 /details 命令
+
+Status: implemented
+
+[English](2026-07-30-tui-details-command.md) | 中文
+
+## Problem
+
+TUI 的 transcript（文本记录）细节状态——工具卡片可见性（`collapsed`/`expanded`/`hidden`，见[整合的 TUI 展示](../architecture/2026-07-28-consolidated-tui-presentation.md)）与 reasoning 块显示——过去只能通过 Ctrl+O 循环和 Ctrl+R 切换来触达。想要某个特定模式的用户必须循环经过其他模式，无法一次操作同时设置两个维度，也无法查询当前状态；吞掉这些控制键的终端更是完全没有替代途径。
+
+## Decision
+
+`dsh-tui` 在其他 agent 作用域命令旁注册 `/details`。裸 `/details` 用一条通知报告当前状态。参数直接命名目标状态：`collapsed|expanded|hidden` 让工具卡片跳到该阶段，`reasoning on|off` 设置 reasoning 显示，裸 `reasoning` 切换它，且指令可在一次调用中组合。未知 token 返回携带用法行的命令错误。命令改动的是与快捷键相同的闭包状态，重构后循环与切换成为 `setToolsVisibility`/`setReasoning` 之上的薄封装；快捷键及其通知保持不变。
+
+组合调用先应用 reasoning 再应用可见性，因为 `setReasoning` 会从会话事件重建 transcript，而重建会丢弃非持久的通知组件；若最后才应用它，会抹掉刚追加的可见性通知。
+
+reasoning 重建暴露了一个重放缺陷，本变更在 `renderEvent` 中修复：实时路径会在同一步骤的后续 `assistant/message` 之前清除已结算的 `StreamingAssistantComponent`（因此第二条消息获得新组件），但 `rebuildTranscript` 重放复用了已结算组件，`settle()` 覆盖其内容，静默丢掉了前一条消息的文本。已结算检查现在位于 `renderEvent` 的 `assistant/message` 分支——两条路径共用一个归属地——此前错误的 `untrusted-controls` 快照（reasoning 与文本被丢弃后只剩空 `Assistant` 标题）已重录为包含内容的版本。

+**裸 `/details` 像 Ctrl+O 一样循环。** 否决：命令相对快捷键的价值在于命名绝对状态；循环命令只是按键更多的快捷键，裸调用作为状态报告更有用。
+
+**拆分 `/tools` 与 `/reasoning` 两个命令。** 否决：两个维度同属一个展示关注点（“transcript 显示多少细节”），单一命令让注册表与 `/help` 列表更小，同时允许一次组合调用。
+
+**按模式提供配置键默认值。** 超出范围：`showReasoning` 已作为配置存在；命令是其上的运行时状态，与快捷键一致。
+
+## Consequences
+
+- 用户可以跳到任意细节模式、一次设置两个维度并查询状态——包括在拦截 Ctrl+O/Ctrl+R 的终端上。
+- 解析器接受无序 token，因此 `/details reasoning expanded` 会切换 reasoning 并展开卡片；每个维度以最后一个指令为准。这一宽松是刻意的，并记录在 README 中。
+- 当一个步骤携带多条 `assistant/message` 事件时，transcript 重建不再丢失 assistant 消息；`details-command` 快照同时固定命令表面与修复后的重放。

@@ -22,7 +22,7 @@ Typing `@` at a token boundary searches files and directories under the session
 
 When optional `ctx.sessionReferences` is mounted, the same `@` menu also offers metadata-only session candidates, inserts `@[label](dsh-session:)`, and prepares the selected snapshots before dispatch. Session references remain structured because the model has no filesystem-like tool for retrieving session snapshots later. Preparation disables duplicate submission and restores the editor input on failure. The TUI chooses `agent.steer()` or `agent.followup()` from the status after that asynchronous preparation, so idle follow-ups still dispatch `agent/prompt-submit` while in-turn steering joins at a checkpoint without that hook.
 
-While the agent is running, ordinary editor submissions call `agent.steer()`; otherwise they call `agent.followup()`. A slash at the start of the submitted line enters `ctx.commands` instead: known commands execute directly, unknown commands produce a warning, and neither path automatically reaches the model. A command producer may explicitly schedule agent work; [`dsh-plan-mode`](../../plan/plan-mode/README.md#model-and-human-surfaces) uses that contract for `/plan [message]`. The TUI registers `/help`, `/model`, `/clear`, `/palette`, `/reload`, `/resume`, `/status`, and `/exit` as agent-scoped definitions; every other effective command joins autocomplete and `/help` dynamically, as do `/skill:` completions. A status line above the editor reports the turn phase the TUI derives from session events — waiting for the first token, thinking, responding, or executing tools — with the elapsed time in that phase and the running step total, refreshed each second, and ends with the `Enter sends steering, Esc cancels` hint; while steering messages wait to reach the model it inserts a `N queued ·` badge before the hint that clears as each drains. Ctrl+C or Escape cancels a running turn. Tool and injected-context cards collapse long bodies into a configurable head/tail preview; Ctrl+O cycles tool cards through collapsed preview, full output, and hidden — the hidden phase drops tool cards from the transcript entirely while context cards stay at their preview, since injected instructions are not tool traffic. The hidden phase also folds each turn's assistant steps into one message: the first step with visible text or reasoning keeps the turn's single `Assistant` header, later steps render as headerless continuations, and a step without a visible body renders nothing; leaving the hidden phase restores the per-step headers. An injected-context card renders its message as prose with the producer's outer reminder frame stripped, so neither the fold nor the frame stripping depends on the payload's syntax. Ctrl+R toggles reasoning, Ctrl+L redraws, and Ctrl+D exits while idle.

Ctrl+R toggles reasoning, Ctrl+L redraws, and Ctrl+D exits while idle. `/details` names the same state those two shortcuts cycle: bare it opens a centered keyboard toggle with one entry per dimension — `Tool cards` and `Reasoning` — showing the live values, where Tab cycles the highlighted entry and applies the change immediately (the transcript behind the dialog is the preview), and Enter, Esc, or Ctrl+C closes; `/details collapsed|expanded|hidden` jumps tool cards to that phase directly, and `/details reasoning [on|off]` sets — or bare `reasoning` toggles — reasoning-block display; arguments combine in one invocation, an unknown argument fails with the usage line, and a combined invocation applies reasoning first so its transcript rebuild never drops the card notice.
 
 `/model` opens the advisory `ctx.llm` catalog as a keyboard selector: a filter box above the list narrows rows by a case-insensitive substring over each row's `provider/model` label, model name, and description, keeping the highlighted row selected when it survives the filter; Up/Down moves, Shift+Tab cycles the focused model's adapter-advertised reasoning efforts in display order, Enter selects the model and effort, and Escape clears a non-empty filter before a second Escape closes it. When an adapter does not advertise a default effort, the cycle also includes `Default`, which clears an explicit selection and preserves the provider default; models without selectable effort metadata ignore Shift+Tab. The selector renders the exact advertised effort list—including `off` when present—and does not synthesize, clamp, or transfer an effort between models. `/model ` still selects an unambiguous model id directly, while `/model /` selects an exact target and uses its adapter default when one exists. The configured target or latest logged request header initializes the selector, and an unlisted current model remains visible because catalogs are advisory. Selection is local to this TUI session. Prompt assembly snapshots the target for one step, replaces `{{provider}}` and `{{model}}`, and applies the same provider/model/reasoning-effort target through `agent/request`; a switch during assembly therefore starts with a later step. The request header durably records targets that reach the model, while an unused selection remains process-local.

 挂载可选的 `ctx.sessionReferences` 后，同一个 `@` 菜单还会提供仅含元数据的会话候选项，插入 `@[label](dsh-session:)`，并在分派前准备所选快照。会话引用保持结构化，因为模型没有类似文件系统的工具可在稍后检索会话快照。准备期间会禁止重复提交，并在失败时恢复编辑器输入。TUI 会在异步准备后根据状态选择 `agent.steer()` 或 `agent.followup()`，因此空闲 followup 仍会分派 `agent/prompt-submit`，而轮次中的 steering 会在检查点加入且不触发该 hook。

 `/model` 将建议性的 `ctx.llm` catalog 打开为键盘选择器：列表上方设有一个过滤框，按对每行 `provider/model` 标签、模型名称和描述的大小写不敏感子串匹配来缩小行集，并在高亮行仍通过过滤时保持其选中状态；Up/Down 移动，Shift+Tab 按显示顺序循环切换适配器为焦点模型公布的推理强度，Enter 选择模型和推理强度，Escape 会先清除非空过滤内容，再次按下才关闭选择器。适配器未公布默认推理强度时，循环还会包含 `Default`，该项会清除显式选择并保留提供方默认行为；没有可选推理强度元数据的模型会忽略 Shift+Tab。选择器会原样呈现公布的推理强度列表（包括存在时的 `off`），不会合成、自动调整或在模型之间转移推理强度。`/model ` 仍可直接选择无歧义的模型 id，`/model /` 则选择精确目标，并在存在时使用其适配器默认值。已配置目标或最新记录的请求 header 会初始化选择器；由于 catalog 仅提供建议，未列出的当前模型仍会显示。选择仅对本 TUI 会话有效。提示词组装会为一个步骤建立目标快照，替换 `{{provider}}` 和 `{{model}}`，并通过 `agent/request` 应用同一个提供方／模型／推理强度目标；因此组装期间的切换会从后续步骤开始生效。请求 header 会持久记录真正到达模型的目标，未使用的选择则只存在于进程本地。

Subject: [PATCH 219/557] feat(tui): bare /details opens a keyboard selector

DetailsDialog is a centered SelectList over the five transcript-detail
states (three tool-card phases, reasoning shown/hidden); it preselects
the current phase, marks both current values, applies on Enter, and
cancels on Esc/Ctrl+C. Width is the new detailsDialogWidth config key.
The argument grammar is unchanged and shares the same setters.

Subject: [PATCH 220/557] fix(web): carry the merged master through the
 add-workspace helper

Master gained a web-search e2e scenario that calls connectFreshWorkspace
with the pre-change one-argument signature, which fails to compile against
the test-merge commit CI builds. Give it the scaffold's workspace root like
every other scenario.

Master also gained the first-run welcome notice. The shared scaffold
acknowledges it before boot, but the W5 smoke spawns its own server against
a fresh $DSH_HOME, so its overlay owns pointer events and swallows the
first click on the workspace chip; the scenario now dismisses the notice
first. The notice is anchored structurally because this spec belongs to the
client TypeScript program, which does not reference the package owning its
copy.

Subject: [PATCH 221/557] feat(tui): two-entry /details selector with Tab
 cycling

DetailsDialog now shows one entry per dimension (Tool cards, Reasoning)
seeded with the current values; Tab cycles the highlighted entry's
pending value (rendered as current -> pending), Enter applies every
changed dimension in one confirm, Esc/Ctrl+C cancels.

Bare `/details` opens `DetailsDialog`, a centered keyboard selector over the five detail states — the three tool-card phases and reasoning shown/hidden — that preselects the current phase, marks both current values, applies the highlighted state on Enter, and cancels on Esc or Ctrl+C; its width is the `detailsDialogWidth` config key and a second `/details` replaces an open selector, mirroring the `/model` overlay.

 After terminal startup succeeds, the package provides the terminal-local `ctx.tui` extension service. A plugin that injects it can call `openOverlay()` with a component factory and constrained layout options; the host exposes the viewport, semantic theme, display-text escaping, redraw, close, and a lifetime signal, but not the pi-tui tree, terminal, focus controller, or overlay handle. Plugin overlays, the model selector, and user questions share one FIFO modal queue. Each request is an effect of the calling plugin fiber, so unload removes queued work or closes visible work before cleanup settles; terminal shutdown unloads dependents before stopping pi-tui. Overlay state is not logged or replayed. Component code is trusted and may render ANSI styling, but must pass untrusted text through `host.display()`. The [interactive-extension Agent Note](../../../.agents/notes/implemented/architecture/2026-07-22-tui-interactive-extension-service.md) owns the boundary and rejected alternatives.
 
-The TUI rebuilds resumed history from the append-origin session events, renders Markdown responses and reasoning, applies each tool's `presentCall` / `presentResult` intent to terminal, diff, or generic cards, keeps the standing `todo/write` plan above the editor (cleared on the next `turn/start`), and presents `ctx.userInteraction` questions in a wide bottom-left keyboard panel with progress, numbered options, and aligned descriptions. The latest logged session title becomes the header subtitle, with `welcome` before a title exists, and the terminal window title becomes ` — `. A durable `llm/retry` event retracts the failed step's live chunks and renders the scheduled retry count, delay, and failure in the transcript; success, exhaustion, and cancellation then settle through ordinary session events. The footer totals each logged model step's usage once, including failed attempts, while treating committed-message usage as a fallback for logs without a usage chunk. Its idle view compares token-meter pressure with `ctx.llm.resolveModelInfo()` context for the current route, displays `context unknown` when the adapter has no capacity metadata, and also shows tool-card mode plus the current model and any explicitly selected reasoning effort; while the agent runs, an elapsed working indicator and `esc interrupt` replace that summary. A surface replacement never rewrites the rendered transcript: the conversation it shadows stays readable, and a landed compaction checkpoint adds one dim `… earlier context was compacted …` marker at its log position, so the terminal reports where the model stopped seeing that history instead of erasing it. Model-only replacement copies — a pruned tool result, a regenerated assistant message — render nothing.

 When optional `ctx.sessionReferences` is mounted, the same `@` menu also offers metadata-only session candidates, inserts `@[label](dsh-session:)`, and prepares the selected snapshots before dispatch. Session references remain structured because the model has no filesystem-like tool for retrieving session snapshots later. Preparation disables duplicate submission and restores the editor input on failure. The TUI chooses `agent.steer()` or `agent.followup()` from the status after that asynchronous preparation, so idle follow-ups still dispatch `agent/prompt-submit` while in-turn steering joins at a checkpoint without that hook.
 
-While the agent is running, ordinary editor submissions call `agent.steer()`; otherwise they call `agent.followup()`. A slash at the start of the submitted line enters `ctx.commands` instead: known commands execute directly, unknown commands produce a warning, and neither path automatically reaches the model. A command producer may explicitly schedule agent work; [`dsh-plan-mode`](../../plan/plan-mode/README.md#model-and-human-surfaces) uses that contract for `/plan [message]`. The TUI registers `/help`, `/model`, `/clear`, `/details`, `/palette`, `/reload`, `/resume`, `/status`, and `/exit` as agent-scoped definitions; every other effective command joins autocomplete and `/help` dynamically, as do `/skill:` completions. A status line above the editor reports the turn phase the TUI derives from session events — waiting for the first token, thinking, responding, or executing tools — with the elapsed time in that phase and the running step total, refreshed each second, and ends with the `Enter sends steering, Esc cancels` hint; while steering messages wait to reach the model it inserts a `N queued ·` badge before the hint that clears as each drains. Ctrl+C or Escape cancels a running turn. Tool and injected-context cards collapse long bodies into a configurable head/tail preview; Ctrl+O cycles tool cards through collapsed preview, full output, and hidden — the hidden phase drops tool cards from the transcript entirely while context cards stay at their preview, since injected instructions are not tool traffic. The hidden phase also folds each turn's assistant steps into one message: the first step with visible text or reasoning keeps the turn's single `Assistant` header, later steps render as headerless continuations, and a step without a visible body renders nothing; leaving the hidden phase restores the per-step headers. An injected-context card renders its message as prose with the producer's outer reminder frame stripped, so neither the fold nor the frame stripping depends on the payload's syntax. Ctrl+R toggles reasoning, Ctrl+L redraws, and Ctrl+D exits while idle. `/details` names the same state those two shortcuts cycle: bare it opens a centered keyboard toggle with one entry per dimension — `Tool cards` and `Reasoning` — showing the live values, where Tab cycles the highlighted entry and applies the change immediately (the transcript behind the dialog is the preview), and Enter, Esc, or Ctrl+C closes; `/details collapsed|expanded|hidden` jumps tool cards to that phase directly, and `/details reasoning [on|off]` sets — or bare `reasoning` toggles — reasoning-block display; arguments combine in one invocation, an unknown argument fails with the usage line, and a combined invocation applies reasoning first so its transcript rebuild never drops the card notice.

 `/model` opens the advisory `ctx.llm` catalog as a keyboard selector: a filter box above the list narrows rows by a case-insensitive substring over each row's `provider/model` label, model name, and description, keeping the highlighted row selected when it survives the filter; Up/Down moves, Shift+Tab cycles the focused model's adapter-advertised reasoning efforts in display order, Enter selects the model and effort, and Escape clears a non-empty filter before a second Escape closes it. When an adapter does not advertise a default effort, the cycle also includes `Default`, which clears an explicit selection and preserves the provider default; models without selectable effort metadata ignore Shift+Tab. The selector renders the exact advertised effort list—including `off` when present—and does not synthesize, clamp, or transfer an effort between models. `/model ` still selects an unambiguous model id directly, while `/model /` selects an exact target and uses its adapter default when one exists. The configured target or latest logged request header initializes the selector, and an unlisted current model remains visible because catalogs are advisory. Selection is local to this TUI session. Prompt assembly snapshots the target for one step, replaces `{{provider}}` and `{{model}}`, and applies the same provider/model/reasoning-effort target through `agent/request`; a switch during assembly therefore starts with a later step. The request header durably records targets that reach the model, while an unused selection remains process-local.

Missing titles, models, cache input, or context capacity are labeled instead of inferred. The card is terminal-only and does not duplicate the compact footer.

 `/resume` opens a full-viewport keyboard selector instead of a centered dialog. Two scopes cover the same candidate set: the current workspace, which it opens on, and all workspaces, which Tab toggles to. The scope line under the search field names the active scope and the count the other holds, and each row in the all-workspaces scope also reports its own workspace. Toggling clears the search and selection so the highlighted row always belongs to the visible list.
 
 Its focused search field starts immediately after the search glyph and emits pi-tui's cursor marker, so terminal IME composition remains anchored inside the field. Candidates are sorted by last logged activity and searchable by log-backed title or session id, and by workspace label in the all-workspaces scope; each row reports current/live/persisted state, last turn outcome, recent provider/model, and durable goal phase when present. Up/Down and Page Up/Page Down navigate, Enter resumes, Escape clears a non-empty search before a second Escape cancels, and Ctrl+C cancels directly. The current session, a session already live in this runtime, an unreadable log, a session with no recorded workspace to run in, or a session whose logged provider has no current adapter remains visible but disabled; a workspace other than the current one is a scope rather than a disabled reason, because resume enters that directory.

-Agent 运行时，普通编辑器提交会调用 `agent.steer()`；其他时候调用 `agent.followup()`。提交行以斜杠开头时会改为进入 `ctx.commands`：已知命令直接执行，未知命令产生警告，两条路径都不会自动到达模型。命令生产方可以显式调度 agent 工作；[`dsh-plan-mode`](../../plan/plan-mode/README.md#model-and-human-surfaces) 使用该契约实现 `/plan [message]`。TUI 将 `/help`、`/model`、`/clear`、`/details`、`/palette`、`/reload`、`/resume`、`/status` 和 `/exit` 注册为 agent 作用域定义；其他所有有效命令都会动态加入自动补全与 `/help`，`/skill:` 补全也相同。编辑器上方的状态行会报告 TUI 从会话事件派生的轮次阶段，包括等待首个 token、思考、响应或执行工具；它显示该阶段已经过时间和运行中的步骤总数，每秒刷新，并以 `Enter sends steering, Esc cancels` 提示结尾。Steering 消息等待到达模型期间，会在提示前插入 `N queued ·` 徽标，每条消息排空后随即清除。Ctrl+C 或 Escape 会取消运行中的轮次。工具卡片与注入上下文卡片都把长主体折叠为可配置的头尾预览；Ctrl+O 让工具卡片在折叠预览、完整输出、隐藏三种状态间循环——隐藏阶段把工具卡片从 transcript 中完全去掉，而上下文卡片保持预览，因为注入的指令不属于工具流量。隐藏阶段还会把每个轮次的 assistant 步骤折叠为一条消息：第一个有可见文本或 reasoning 的步骤保留该轮次唯一的 `Assistant` 标题，之后的步骤渲染为无标题的续段，没有可见正文的步骤则不渲染任何内容；离开隐藏阶段会恢复每步各自的标题。注入上下文卡片把消息渲染为文本，并去掉生产方的外层提醒外框，因此折叠与去外框都不依赖载荷的语法。Ctrl+R 切换 reasoning，Ctrl+L 重绘，Ctrl+D 在空闲时退出。`/details` 命名的正是这两个快捷键循环的同一份状态：不带参数时打开一个居中的键盘开关，每个维度一个条目——`Tool cards` 与 `Reasoning`——显示实时值，Tab 循环高亮条目并立即应用变更（对话框背后的 transcript 即是预览），Enter、Esc 或 Ctrl+C 关闭；`/details collapsed|expanded|hidden` 让工具卡片直接跳到该阶段，`/details reasoning [on|off]` 设置——或裸 `reasoning` 切换——reasoning 块显示；参数可在一次调用中组合，未知参数会以用法行报错，组合调用先应用 reasoning，使其 transcript 重建不会丢掉卡片通知。

 `/resume` 会打开全 viewport 键盘选择器，而非居中对话框。两个作用域覆盖同一候选项集合：打开时所处的当前工作区，以及按 Tab 切换到的所有工作区。搜索字段下方的作用域行会给出当前作用域的名称以及另一个作用域包含的数量，且在所有工作区作用域中每行还会报告自身所属的工作区。切换会清除搜索与选择，使高亮行始终属于可见列表。
 
 获得焦点的搜索字段紧跟搜索 glyph 开始，并发出 pi-tui 的 cursor marker，使终端 IME 组合保持锚定在字段内。候选项按最近记录的活动排序，可按日志支持的标题或会话 id 搜索，在所有工作区作用域中还可按工作区标签搜索；每行报告 current/live/persisted 状态、上一轮次结果、近期提供方／模型，以及存在时的持久目标阶段。Up/Down 与 Page Up/Page Down 导航，Enter 恢复，Escape 会先清除非空搜索，再次按下才取消，Ctrl+C 则直接取消。当前会话、已在本运行时中活跃的会话、不可读日志、没有可运行的已记录工作区的会话，或日志所记提供方没有当前适配器的会话仍会显示，但不可选择；不同于当前工作区的工作区属于作用域而非禁用原因，因为恢复会进入该目录。

live preview; Enter/Esc/Ctrl+C just close.

 - A user can jump to any detail mode, set both dimensions at once, and see the current state in the selector — including on terminals that intercept Ctrl+O/Ctrl+R.
 - The parser accepts order-free tokens, so `/details reasoning expanded` toggles reasoning and expands cards; last directive wins per dimension. This leniency is deliberate and documented in the README.
-- The selector applies only changed dimensions on confirm, so Enter without a Tab closes silently; a two-dimension change is one open-Tab-Enter interaction.
-- Transcript rebuilds no longer lose assistant messages when a step carries more than one `assistant/message` event; the `details-command` snapshot pins the argument surface and the fixed replay, and `details-selector` pins the open selector with a Tab-cycled `hidden → collapsed` pending value.
+- The selector has no pending state or cancel: every Tab is a real, already-notified change, and closing never reverts. A user who over-cycles simply Tabs on to the wanted value.
+- Transcript rebuilds no longer lose assistant messages when a step carries more than one `assistant/message` event; the `details-command` snapshot pins the argument surface and the fixed replay, and `details-selector` pins the open toggle right after a Tab applied `hidden` -> `collapsed`, including the restored tool card behind it.

 When optional `ctx.sessionReferences` is mounted, the same `@` menu also offers metadata-only session candidates, inserts `@[label](dsh-session:)`, and prepares the selected snapshots before dispatch. Session references remain structured because the model has no filesystem-like tool for retrieving session snapshots later. Preparation disables duplicate submission and restores the editor input on failure. The TUI chooses `agent.steer()` or `agent.followup()` from the status after that asynchronous preparation, so idle follow-ups still dispatch `agent/prompt-submit` while in-turn steering joins at a checkpoint without that hook.
 
-While the agent is running, ordinary editor submissions call `agent.steer()`; otherwise they call `agent.followup()`. A slash at the start of the submitted line enters `ctx.commands` instead: known commands execute directly, unknown commands produce a warning, and neither path automatically reaches the model. A command producer may explicitly schedule agent work; [`dsh-plan-mode`](../../plan/plan-mode/README.md#model-and-human-surfaces) uses that contract for `/plan [message]`. The TUI registers `/help`, `/model`, `/clear`, `/details`, `/palette`, `/reload`, `/resume`, `/status`, and `/exit` as agent-scoped definitions; every other effective command joins autocomplete and `/help` dynamically, as do `/skill:` completions. A status line above the editor reports the turn phase the TUI derives from session events — waiting for the first token, thinking, responding, or executing tools — with the elapsed time in that phase and the running step total, refreshed each second, and ends with the `Enter sends steering, Esc cancels` hint; while steering messages wait to reach the model it inserts a `N queued ·` badge before the hint that clears as each drains. Ctrl+C or Escape cancels a running turn. Tool and injected-context cards collapse long bodies into a configurable head/tail preview; Ctrl+O cycles tool cards through collapsed preview, full output, and hidden — the hidden phase drops tool cards from the transcript entirely while context cards stay at their preview, since injected instructions are not tool traffic. The hidden phase also folds each turn's assistant steps into one message: the first step with visible text or reasoning keeps the turn's single `Assistant` header, later steps render as headerless continuations, and a step without a visible body renders nothing; leaving the hidden phase restores the per-step headers. An injected-context card renders its message as prose with the producer's outer reminder frame stripped, so neither the fold nor the frame stripping depends on the payload's syntax. Ctrl+R toggles reasoning, Ctrl+L redraws, and Ctrl+D exits while idle. `/details` names the same state those two shortcuts cycle: bare it opens a centered keyboard selector with one entry per dimension — `Tool cards` and `Reasoning` — seeded with the current values, where Tab cycles the highlighted entry's pending value (rendered as `current → pending`), Enter applies every changed dimension and closes, and Esc or Ctrl+C cancels without changing anything; `/details collapsed|expanded|hidden` jumps tool cards to that phase directly, and `/details reasoning [on|off]` sets — or bare `reasoning` toggles — reasoning-block display; arguments combine in one invocation, an unknown argument fails with the usage line, and a combined invocation applies reasoning first so its transcript rebuild never drops the card notice.

 `/model` opens the advisory `ctx.llm` catalog as a keyboard selector: a filter box above the list narrows rows by a case-insensitive substring over each row's `provider/model` label, model name, and description, keeping the highlighted row selected when it survives the filter; Up/Down moves, Shift+Tab cycles the focused model's adapter-advertised reasoning efforts in display order, Enter selects the model and effort, and Escape clears a non-empty filter before a second Escape closes it. When an adapter does not advertise a default effort, the cycle also includes `Default`, which clears an explicit selection and preserves the provider default; models without selectable effort metadata ignore Shift+Tab. The selector renders the exact advertised effort list—including `off` when present—and does not synthesize, clamp, or transfer an effort between models. `/model ` still selects an unambiguous model id directly, while `/model /` selects an exact target and uses its adapter default when one exists. The configured target or latest logged request header initializes the selector, and an unlisted current model remains visible because catalogs are advisory. Selection is local to this TUI session. Prompt assembly snapshots the target for one step, replaces `{{provider}}` and `{{model}}`, and applies the same provider/model/reasoning-effort target through `agent/request`; a switch during assembly therefore starts with a later step. The request header durably records targets that reach the model, while an unused selection remains process-local.

The harness keeps all user data under one root; there is no XDG config/data/cache split. `dshHomePath(...segments)` joins deployment-owned children onto that root, and `dsh-app-boot` exposes it to Loader `!!js` config expressions before mounting entries, so shipped compositions derive `sessions` and `storages` without copying the resolver. `dshHomeDisplay()` names a resolved root symbolically for user-facing paths — `~/.dsh` for the default home, `$DSH_HOME` for any configured home — so the user-global `AGENTS.md` label never leaks an absolute machine path.

 `@deepseek-ai/dsh-home` is deleted. Its three importers (`dsh-tool-bash`, `dsh-skill-local`, `dsh-agent-spine-demo`) now import `resolveDshHome` from `dsh-paths`. `dsh-telemetry`'s `globalConfigDir` delegates to `resolveDshHome`, dropping its second resolver, the `DSH_CONFIG_HOME` override, the XDG/`%APPDATA%` branches, and the `deepseek-harness` namespace; the anonymous id now lives directly under the harness home.

 **Scope, not exclusion.** A workspace other than the current one is a display scope rather than a disabled reason. `showResume()` summarizes every record and the `ResumePicker` owns a `scope` of `'workspace' | 'all'`, defaulting to the current workspace so the common case is unchanged. Tab toggles; the scope line names the active scope and the count the other holds; each row in the all-workspaces scope reports its own workspace, and that label joins the searchable text only in the scope that shows it. A toggle clears the query and selection so the highlighted row always belongs to the visible list, and the per-row workspace line makes a row one terminal row taller in that scope, which the visible-count budget accounts for.

-- **Shipped**: the Web overlay anchors `storage-json.root` to `$DSH_HOME/storages` directly in the row, with the same `!!js` IIFE the session root uses (`~/.dsh/storages` by default, beside `~/.dsh/sessions`; no leading dot — the home is already a hidden tree). The user ruled this form in over this section's original launcher-patch + `storageRoot` profile key (see Alternatives); per-row overrides ride the personal `~/.dsh/config.yaml` patch layer. The verbatim duplication of the expression against the session root (`base.cordis.yml`) is a known cost — acceptable at two consumers; a third `$DSH_HOME`-derived root triggers extracting a single source (a launcher variable or a shared expression). The web e2e scaffold already patches the row to an absolute temp root, so tests never touch the user's home.

The web e2e scaffold already patches the row to an absolute temp root, so tests never touch the user's home.
 - **Still open**: `JsonStorageBackend` resolves its configured root once at construction (`resolve(config.root)`), adopting the JSONL backend's recorded rationale verbatim: a later `process.cwd()` change must not split one backend across roots. The SQLite storage backend already resolves its path.
 - Pre-release stance applies (and was executed): no migration shim. A deployment that cached under `/.storages` re-derives everything (workspace re-bootstraps from the header index; the projection cache refolds lazily) or moves the two json files by hand once.

Subject: [PATCH 226/557] fix(fixture): drop deleted search-row.module.css from
 glob path sample

The ToolRow refactor deleted the per-row CSS modules, but the glob search
fixture still listed search-row.module.css as a sample path, which
verify-package-paths rejects as a broken packages/* reference. Point it at the
search-card spec instead.

+# Agent Note: Third-party memory MCP examples
+
+Status: implemented

+
+## Problem
+
+A direct vendor integration made one provider's API, configuration, health behavior, and tool semantics part of DSH. That was too much product surface for a capability already expressible through MCP, and it would require repeating the same adaptation for every memory system. Users instead need a small, inspectable way to opt into one external memory server while preserving the generic MCP boundary.
+
+The acceptance bar is stronger than "the socket connects": each reference must support a real DSH write in session A, recall from the provider in a fresh DSH session B, and use of the recalled value. At the same time, provider downloads, accounts, models, embeddings, storage initialization, and separate HTTP processes must remain upstream responsibilities.
+
+## Decision
+
+Ship three default-off Cordis overlay examples under `examples/mcp-memory`: Memorix, MCP Reference Memory, and Engram. Every file inserts exactly one `@deepseek-ai/dsh-mcp-client` row. None is referenced by the shipped composition, and the CLI declares the generic bridge only so an explicitly selected overlay can resolve it.
+
+These third-party configurations are provided as interoperability examples only. Their inclusion does not imply endorsement, recommendation, partnership, or ongoing support by DeepSeek. There is no memory preset registry, vendor-specific DSH plugin, universal memory service, installation UI, migration layer, health checker, or reconnect controller. Another memory MCP server uses the same documented stdio or Streamable HTTP row.
+
+## Responsibility boundary
+
+| Concern | DSH | Upstream provider or user |
+|---|---|---|
+| Parse selected overlay | Yes | Select one file |
+| Start stdio command and stop it on plugin disposal | Yes | Install the pinned executable |
+| Connect to Streamable HTTP and discover tools | Yes | Run and supervise the HTTP service |
+| Register tools as `mcp____` | Yes | Define tool schemas and behavior |
+| Account, auth, model, embedding, storage initialization | No | Yes |
+| Vendor data migration, retry, crash recovery | No | Yes |
+
+The generic stdio transport scrubs ambient credential-shaped and `DSH_*` variables. Baseline examples explicitly map only the variables they require; optional provider secrets must be added to `config.env` or configured in the provider's own files.
+
+## Pins and identity
+
+| Provider | Tested contract |
+|---|---|
+| Memorix | npm `1.3.0`, tag commit `500792cad3144142293bfbb20acb4841c9f7fcfa` |
+| MCP Reference Memory | npm `2026.7.4`, package commit `6dd0a683e198783e30feabf7abaf42f925bd18b1` |
+| Engram | tag `v1.20.0`, commit `ba9e46ced152c37a7cb9e576153c41995873e2fc` |
+
+`DSH_MEMORY_USER_ID` is a stable user partition, not a DSH session id. Each example maps it to a separate provider data path under `$DSH_HOME`.
+
+Project identity remains provider-owned: Memorix and Engram use the DSH working directory's Git project, with Engram optionally accepting `ENGRAM_PROJECT`.
+
+## Model guidance
+
+The examples do not patch `@deepseek-ai/dsh-system-prompt`: a config patch replaces a row's complete config and could erase an existing persona. The README instead offers one optional additive instruction:
+
+> When the user asks you to remember something, call a memory write tool. When historical information may be relevant, search memory and use relevant results.
+
+Provider tool descriptions remain authoritative.
+
+## Validation contract
+
+Remote CI never contacts third-party services or consumes secrets. The keyless suite parses all three overlay files, checks their generic bridge and secret boundary, replaces the upstream endpoint with the package-owned MCP fixture server, boots the real Cordis Loader, and proves tool discovery.
+
+Before merge, manual evidence for every pinned provider must separately show:
+
+1. DSH session A calls a write tool and receives success for a unique value.
+2. Fresh DSH session B, under the same provider/user scope, calls search or recall and returns that value without session A's transcript.
+3. Session B uses the recalled value in a subsequent answer.
+
+"Fresh session" means a new DSH session in the same Host. No Host restart is required. The generic MCP client discovers asynchronously and has no automatic reconnect after a child or HTTP transport closes; validation waits for tools before the first turn and uses HMR or a Host restart only after a crash.
+
+## Alternatives considered
+
+**One DSH plugin per provider.** Rejected because it repeats auth, configuration, lifecycle, and tool wrappers that MCP already standardizes and expands ownership for every added provider.
+
+**A memory-provider preset registry.** Rejected because a registry would make third-party versions and recommendations look like a supported DSH product surface. Copyable overlays keep ownership and drift visible.
+
+**Run `npx` or `go run` inside the MCP row.** Rejected after probes showed first-run npm downloads can exceed the MCP initialization timeout and an interrupted `npx` cache can become unusable. DSH starts a server process; it is not the provider package manager. Pinned installation commands are explicit prerequisites.
+
+**Inject the common instruction from the generic MCP client.** Rejected because the bridge serves non-memory MCP servers too, and generic prompt mutation would reintroduce provider semantics into shared runtime code.
+
+## Consequences
+
+Selecting a file gives the model the provider's complete discovered MCP tool surface, with schema/token cost determined by that provider. Removing `--config` removes the memory server. Users accept each upstream license, data policy, cloud cost, and operational model directly.
+
+The earlier vendor-specific change is superseded by this generic path. Future provider drift is handled by updating and revalidating a small example pin rather than adding runtime branches to DSH.

+# Agent Note: 第三方记忆 MCP 示例
+
+Status: implemented
+
+[English](2026-07-31-third-party-memory-mcp-examples.md) | 中文
+
+## 问题
+
+直接集成某个提供方会使该提供方的 API、配置、健康状态行为和工具语义成为 DSH 的一部分。对于已经可以通过 MCP 表达的功能，这会让产品接口过于庞大，而且每接入一个记忆系统都需要重复同样的适配工作。用户需要的是一种精简、可检查的方式，在保留通用 MCP 边界的同时，选择启用一个外部记忆服务器。
+
+验收标准不止于「套接字可以连接」：每份参考配置都必须支持 DSH 在会话 A 中实际写入，在新的 DSH 会话 B 中从提供方召回，并使用召回的值。与此同时，提供方下载、账户、模型、embedding、存储初始化和独立 HTTP 进程仍由上游负责。
+
+## 决策
+
+在 `examples/mcp-memory` 下交付三份默认关闭的 Cordis overlay 示例：Memorix、MCP Reference Memory 和 Engram。每个文件只插入一个 `@deepseek-ai/dsh-mcp-client` 配置项。交付组合不会引用这些文件；CLI（命令行界面）仅声明通用桥接器，使用户显式选择 overlay 时可以解析它。
+
+这些第三方配置仅作为互操作参考；收录不代表 DeepSeek 的认可、推荐、合作关系或持续支持承诺。系统没有记忆预设注册表、提供方专属 DSH 插件、通用记忆服务、安装 UI、迁移层、健康检查器或重连控制器。其他记忆 MCP 服务器可以使用同一份文档中的 stdio 或 Streamable HTTP 配置项。
+
+## 职责边界
+
+| 事项 | DSH | 上游提供方或用户 |
+|---|---|---|
+| 解析选中的 overlay | 是 | 选择一个文件 |
+| 启动 stdio 命令，并在插件 dispose（资源释放）时将其停止 | 是 | 安装固定版本的可执行文件 |
+| 连接 Streamable HTTP 并发现工具 | 是 | 运行并监管 HTTP 服务 |
+| 以 `mcp____` 注册工具 | 是 | 定义工具 schema 和行为 |
+| 账户、认证、模型、embedding、存储初始化 | 否 | 是 |
+| 提供方数据迁移、重试、崩溃恢复 | 否 | 是 |
+
+通用 stdio 传输会清除环境中名称类似凭据的变量和 `DSH_*` 变量。基线示例仅显式映射自己需要的变量；可选的提供方密钥必须添加到 `config.env`，或配置在提供方自己的文件中。
+
+## 版本固定与身份
+
+| 提供方 | 已测试契约 |
+|---|---|
+| Memorix | npm `1.3.0`，tag commit `500792cad3144142293bfbb20acb4841c9f7fcfa` |
+| MCP Reference Memory | npm `2026.7.4`，package commit `6dd0a683e198783e30feabf7abaf42f925bd18b1` |
+| Engram | tag `v1.20.0`，commit `ba9e46ced152c37a7cb9e576153c41995873e2fc` |
+
+`DSH_MEMORY_USER_ID` 是稳定的用户分区，不是 DSH 会话 id。每份示例都将其映射到 `$DSH_HOME` 下相互独立的提供方数据路径。
+
+项目身份仍由提供方负责：Memorix 和 Engram 使用 DSH 工作目录中的 Git 项目，其中 Engram 还可以选择接受 `ENGRAM_PROJECT`。
+
+## 模型指导
+
+示例不会修改 `@deepseek-ai/dsh-system-prompt`：配置 patch 会替换某个配置项的完整配置，可能抹除已有 persona。README 改为提供一条可选的附加指令：
+
+> 用户要求记住时调用写入工具；涉及历史信息时，主动检索并使用相关记忆。
+
+提供方的工具描述仍然是权威定义。
+
+## 验证契约
+
+远程 CI 不会访问第三方服务或消耗密钥。无密钥套件解析全部三份 overlay 文件，检查其通用桥接器和密钥边界，将上游端点替换为包自带的 MCP fixture（测试前置数据）服务器，通过真实 Cordis Loader 启动，并验证工具发现。
+
+合并前，每个固定版本的提供方都必须分别提供以下人工证据：
+
+1. DSH 会话 A 调用写入工具，为一个唯一值写入记忆，并收到成功结果。
+2. 新的 DSH 会话 B 在相同提供方／用户范围下调用搜索或召回，不借助会话 A 的 transcript（文本记录）便可返回该值。
+3. 会话 B 在后续回答中使用该召回值。
+
+「新会话」是指同一个 Host 中新建的 DSH 会话，不需要重启 Host。通用 MCP 客户端以异步方式发现工具，子进程或 HTTP 传输关闭后不会自动重连；验证会在第一轮之前等待工具出现，并且只在崩溃后使用 HMR 或重启 Host。
+
+## 考虑过的替代方案
+
+**每个提供方使用一个 DSH 插件。** 不予采纳，因为这会重复 MCP 已经标准化的认证、配置、生命周期和工具包装层，并随着每增加一个提供方而扩大维护范围。
+
+**记忆提供方预设注册表。** 不予采纳，因为注册表会让第三方版本和推荐看起来像受支持的 DSH 产品接口。可复制的 overlay 让所有权和版本偏移保持可见。
+
+**在 MCP 配置项内运行 `npx` 或 `go run`。** 不予采纳，因为探测表明首次 npm 下载可能超过 MCP 初始化超时，而中断的 `npx` 缓存可能变得不可用。DSH 负责启动服务器进程，不是提供方的包管理器。固定版本的安装命令属于显式前置条件。
+
+**由通用 MCP 客户端注入共用指令。** 不予采纳，因为该桥接器也服务于非记忆类 MCP 服务器，而且通用提示词变更会把提供方语义重新带入共享运行时代码。
+
+## 后果
+
+选择一个文件后，模型可以使用提供方发现到的完整 MCP 工具接口；工具 schema 和 token 成本由提供方决定。移除 `--config` 就会移除记忆服务器。用户直接接受各上游的许可证、数据政策、云服务费用和运维模式。
+
+通用方案取代了早期针对特定提供方的改动。未来出现提供方版本偏移时，只需更新并重新验证一份小型示例的固定版本，不必向 DSH 添加运行时分支。

 Runnable demos (not workspaces) that showcase how the harness is wired. Each example is a **thin leaf**: either a `cordis.yml` tree that picks swappable backends and loads one app package, or an **overlay** — a patch list `dsh --config` applies over the shipped composition ([`apps/cli/config/base.cordis.yml`](../apps/cli/config/base.cordis.yml) plus a surface overlay). Bundled compositions live in [`@deepseek-ai/dsh-cli-demo`](../packages/examples/cli-demo), [`@deepseek-ai/dsh-acp-demo`](../packages/examples/acp-demo), and their shared [`@deepseek-ai/dsh-agent-spine-demo`](../packages/examples/agent-spine-demo) bundle; the `dsh` surfaces use flat config trees instead. There is no `start.ts`; the terminal `demo:*` scripts boot through the [`dsh`](../apps/cli/README.md) CLI, and the headless/ACP scripts invoke the `cli-demo`/`acp-demo` bins.

+# Third-party memory MCP examples
+
+English | [中文](README.zh.md)
+
+These three **default-off reference configurations** connect one memory system to DSH through [`@deepseek-ai/dsh-mcp-client`](../../packages/mcp/mcp-client/README.md). Pick one, or copy the same generic MCP row for another server.
+
+These third-party configurations are provided as interoperability examples only. Their inclusion does not imply endorsement, recommendation, partnership, or ongoing support by DeepSeek.
+
+## What DSH does
+
+DSH parses the selected Cordis overlay, starts a configured stdio command or connects to a configured Streamable HTTP URL, discovers MCP tools, and exposes them as `mcp____`. DSH does **not** download the server, initialize its database, choose its model or embedding provider, create a cloud account, migrate vendor data, or supervise a separate HTTP service. For stdio, the generic client launches and stops the child with the DSH plugin lifecycle; for HTTP, the upstream service must already be running.
+
+The stdio bridge deliberately removes ambient credential-shaped and `DSH_*` variables before launching a child. Each example explicitly forwards only the variables needed for its baseline. If an optional upstream feature needs another secret, add that variable to the row's `config.env` instead of putting the secret directly in YAML.
+
+## Choose one
+
+| System | Tested pin | Transport | Upstream prerequisite |
+|---|---:|---|---|
+| [Memorix](https://github.com/AVIDS2/memorix) | `memorix@1.3.0` (`500792cad3144142293bfbb20acb4841c9f7fcfa`) | stdio | Node 22.18+ and `npm install --global memorix@1.3.0` |
+| [MCP Reference Memory](https://github.com/modelcontextprotocol/servers/tree/main/src/memory) | `@modelcontextprotocol/server-memory@2026.7.4` (`6dd0a683e198783e30feabf7abaf42f925bd18b1`) | stdio | `npm install --global @modelcontextprotocol/server-memory@2026.7.4` |
+| [Engram](https://github.com/Gentleman-Programming/engram) | `v1.20.0` (`ba9e46ced152c37a7cb9e576153c41995873e2fc`) | stdio | Go 1.25.10+ and `go install github.com/Gentleman-Programming/engram/cmd/engram@v1.20.0`, or the matching release binary |
+
+## Enable one
+
+Use a stable user id across sessions, then pass one overlay to DSH:
+
+```sh
+export DSH_MEMORY_USER_ID=alice
+dsh --config "$PWD/examples/mcp-memory/memorix.cordis.yml"
+```
+
+Replace the filename with `mcp-reference-memory.cordis.yml` or `engram.cordis.yml`. The path may point to a copied file anywhere on disk. No memory server is present in the shipped composition, so omitting `--config` keeps all three disabled.
+
+To keep the selection in personal configuration, merge the chosen file's single `insert` patch into `$DSH_HOME/config.yaml` (normally `~/.dsh/config.yaml`). Do not copy over an existing file: it may already contain unrelated personal patches.
+
+## Provider setup
+
+### Memorix
+
+```sh
+npm install --global memorix@1.3.0
+export DSH_MEMORY_USER_ID=alice
+dsh --config "$PWD/examples/mcp-memory/memorix.cordis.yml"
+```
+
+Memorix works in local heuristic mode without an LLM or embedding service. Configure optional providers in Memorix's own `~/.memorix/config.toml` or project `memorix.toml`. The example keeps Memorix's Git-project identity from the DSH working directory and maps `DSH_MEMORY_USER_ID` to a private `MEMORIX_DATA_DIR`.
+
+### MCP Reference Memory
+
+```sh
+npm install --global @modelcontextprotocol/server-memory@2026.7.4
+export DSH_MEMORY_USER_ID=alice
+dsh --config "$PWD/examples/mcp-memory/mcp-reference-memory.cordis.yml"
+```
+
+This reference server stores a local knowledge graph and exposes entity, relation, observation, read, search, and open tools. It needs no model or embedding service. The example maps `DSH_MEMORY_USER_ID` to an isolated `MEMORY_FILE_PATH`.
+
+### Engram
+
+```sh
+go install github.com/Gentleman-Programming/engram/cmd/engram@v1.20.0
+export DSH_MEMORY_USER_ID=alice
+dsh --config "$PWD/examples/mcp-memory/engram.cordis.yml"
+```
+
+The example maps the user id to an isolated `ENGRAM_DATA_DIR`. Engram still owns project selection: it detects the Git project from the DSH working directory, or accepts `ENGRAM_PROJECT` as an explicit override.
+
+## Optional shared model instruction
+
+Add this short, vendor-neutral instruction to your existing model instructions if the server's tool descriptions do not trigger memory use reliably:
+
+> When the user asks you to remember something, call a memory write tool. When historical information may be relevant, search memory and use relevant results.
+
+This is additive guidance only. The examples do not replace DSH's system-prompt persona.
+
+## Verify write, fresh-session recall, and use
+
+Use one unique value, the same provider scope, and the same `DSH_MEMORY_USER_ID` throughout:
+
+1. In DSH session A, ask: `Remember that my validation drink is lapsang-.` Confirm the model called the provider's write tool and the tool returned success.
+2. Create DSH session B in the same running Host. Do not copy session A's conversation. Ask: `What is my validation drink? Check memory.` Confirm the model called the provider's search or recall tool and returned the value.
+3. Still in session B, ask: `Use that preference to suggest one drink for the meeting.` Confirm the answer uses the recalled value.
+
+A new DSH session is required; a Host restart is not. Restart or HMR is needed only after an MCP child crashes because the current generic client unregisters tools on disconnect and does not auto-reconnect. Initial discovery is asynchronous, so wait for the provider's `mcp__...` tools before sending the first validation prompt.
+
+## Bring another MCP server
+
+Copy the same generic shape and use a unique `id` and `serverName`:
+
+```yaml
+- insert:
+    - id: memory-my-server
+      name: '@deepseek-ai/dsh-mcp-client'
+      config:
+        serverName: my-memory
+        transport: stdio
+        command: my-memory-mcp
+        args: []
+        env: {}
+        cwd: !!js process.cwd()
+```
+
+For a remote server, use `transport: streamable-http`, `url`, and `headers` instead. Provider-specific installation, identity, authentication, models, embeddings, persistence, and licensing remain the provider's responsibility.

+# 第三方记忆 MCP 示例
+
+[English](README.md) | 中文
+
+这三份**默认关闭的参考配置** 通过 [`@deepseek-ai/dsh-mcp-client`](../../packages/mcp/mcp-client/README.md) 将一个记忆系统连接到 DSH。请选择其中一份，或复制相同的通用 MCP 配置项来连接其他服务器。
+
+这些第三方配置仅作为互操作参考；收录不代表 DeepSeek 的认可、推荐、合作关系或持续支持承诺。
+
+## DSH 负责什么
+
+DSH 解析选中的 Cordis overlay，启动已配置的 stdio 命令或连接已配置的 Streamable HTTP URL，发现 MCP 工具，并以 `mcp____` 的形式公开这些工具。DSH **不负责** 下载服务器、初始化其数据库、选择模型或 embedding 提供方、创建云端账户、迁移提供方数据，也不监管独立的 HTTP 服务。对于 stdio，通用客户端会随 DSH 插件生命周期启动和停止子进程；对于 HTTP，上游服务必须已经运行。
+
+stdio 桥接器在启动子进程前会主动移除环境中名称类似凭据的变量和 `DSH_*` 变量。每份示例仅显式转发其基线运行所需的变量。如果某个可选的上游功能还需要其他密钥，请将该变量添加到配置项的 `config.env`，不要把密钥直接写进 YAML。
+
+## 选择一个
+
+| 系统 | 已测试版本 | 传输方式 | 上游前置条件 |
+|---|---:|---|---|
+| [Memorix](https://github.com/AVIDS2/memorix) | `memorix@1.3.0`（`500792cad3144142293bfbb20acb4841c9f7fcfa`） | stdio | Node 22.18+，并执行 `npm install --global memorix@1.3.0` |
+| [MCP Reference Memory](https://github.com/modelcontextprotocol/servers/tree/main/src/memory) | `@modelcontextprotocol/server-memory@2026.7.4`（`6dd0a683e198783e30feabf7abaf42f925bd18b1`） | stdio | `npm install --global @modelcontextprotocol/server-memory@2026.7.4` |
+| [Engram](https://github.com/Gentleman-Programming/engram) | `v1.20.0`（`ba9e46ced152c37a7cb9e576153c41995873e2fc`） | stdio | Go 1.25.10+，并执行 `go install github.com/Gentleman-Programming/engram/cmd/engram@v1.20.0`，或安装匹配的发布版二进制文件 |
+
+## 启用一个
+
+在多个会话间使用一个稳定的用户 id，然后将一份 overlay 传给 DSH：
+
+```sh
+export DSH_MEMORY_USER_ID=alice
+dsh --config "$PWD/examples/mcp-memory/memorix.cordis.yml"
+```
+
+请将文件名替换为 `mcp-reference-memory.cordis.yml` 或 `engram.cordis.yml`。该路径可以指向磁盘任意位置的一份复制文件。交付组合不包含任何记忆服务器，因此不传 `--config` 就会让这三项全部保持关闭。
+
+如果要把所选配置保存在个人配置中，请将对应文件中的单个 `insert` patch 合并到 `$DSH_HOME/config.yaml`（通常是 `~/.dsh/config.yaml`）。不要覆盖已有文件，其中可能已经包含无关的个人 patch。
+
+## 提供方设置
+
+### Memorix
+
+```sh
+npm install --global memorix@1.3.0
+export DSH_MEMORY_USER_ID=alice
+dsh --config "$PWD/examples/mcp-memory/memorix.cordis.yml"
+```
+
+Memorix 无需 LLM（大语言模型）或 embedding 服务，即可在本地启发式模式下运行。请在 Memorix 自己的 `~/.memorix/config.toml` 或项目 `memorix.toml` 中配置可选提供方。该示例沿用 DSH 工作目录中的 Git 项目标识，并将 `DSH_MEMORY_USER_ID` 映射到独立的 `MEMORIX_DATA_DIR`。
+
+### MCP Reference Memory
+
+```sh
+npm install --global @modelcontextprotocol/server-memory@2026.7.4
+export DSH_MEMORY_USER_ID=alice
+dsh --config "$PWD/examples/mcp-memory/mcp-reference-memory.cordis.yml"
+```
+
+该参考服务器存储本地知识图谱，并公开实体、关系、观察、读取、搜索和打开工具。它不需要模型或 embedding 服务。该示例将 `DSH_MEMORY_USER_ID` 映射到隔离的 `MEMORY_FILE_PATH`。
+
+### Engram
+
+```sh
+go install github.com/Gentleman-Programming/engram/cmd/engram@v1.20.0
+export DSH_MEMORY_USER_ID=alice
+dsh --config "$PWD/examples/mcp-memory/engram.cordis.yml"
+```
+
+该示例将用户 id 映射到隔离的 `ENGRAM_DATA_DIR`。Engram 仍负责选择项目：它从 DSH 工作目录检测 Git 项目，也接受 `ENGRAM_PROJECT` 作为显式覆盖。
+
+## 可选的共用模型指令
+
+如果服务器的工具描述无法可靠触发记忆使用，请将以下简短、与提供方无关的指令添加到你现有的模型指令中：
+
+> 用户要求记住时调用写入工具；涉及历史信息时，主动检索并使用相关记忆。
+
+这只是附加指导。示例不会替换 DSH 系统提示词中的 persona。
+
+## 验证写入、新会话召回和使用
+
+请在整个过程中使用一个唯一值、相同的提供方范围和相同的 `DSH_MEMORY_USER_ID`：
+
+1. 在 DSH 会话 A 中提出：`Remember that my validation drink is lapsang-.`。确认模型调用了提供方的写入工具，并且工具返回成功。
+2. 在同一个仍在运行的 Host 中创建 DSH 会话 B。不要复制会话 A 的对话。提出：`What is my validation drink? Check memory.`。确认模型调用了提供方的搜索或召回工具，并返回该值。
+3. 继续在会话 B 中提出：`Use that preference to suggest one drink for the meeting.`。确认回答使用了召回的值。
+
+必须新建 DSH 会话，但不需要重启 Host。只有 MCP 子进程崩溃后才需要重启或执行 HMR（热模块替换），因为当前的通用客户端会在连接断开时注销工具，且不会自动重连。初始发现过程是异步的，因此发送第一条验证提示词前，请等待提供方的 `mcp__...` 工具出现。
+
+## 接入其他 MCP 服务器
+
+复制相同的通用结构，并使用唯一的 `id` 和 `serverName`：
+
+```yaml
+- insert:
+    - id: memory-my-server
+      name: '@deepseek-ai/dsh-mcp-client'
+      config:
+        serverName: my-memory
+        transport: stdio
+        command: my-memory-mcp
+        args: []
+        env: {}
+        cwd: !!js process.cwd()
+```
+
+对于远程服务器，请改用 `transport: streamable-http`、`url` 和 `headers`。提供方专属的安装、身份、认证、模型、embedding、持久化和许可仍由提供方负责。

The active registrant receives `complete()` and `openSection(id)`; no later step mounts until ownership transfers. The product welcome registers at order `-100`, while `ui-models` retains only the conditional DeepSeek readiness and credential-routing step at order `0`.

The notice is browser UI only: it creates no Session event and contributes no model-visible content.

 **Acknowledgement is durable per Harness profile.** The Host half registers a `ui-onboarding` section in the user-settings seam, stored under the active `$DSH_HOME/settings.yaml`. The browser shows the notice unless `welcomeNoticeVersion` equals the owner constant exactly. Continue applies one path mutation with the current version and calls `complete()` only after the Host commits it; a failed write leaves the notice open, and closing the page or process writes nothing. Bumping the constant intentionally makes every profile acknowledge the revised copy once.

The stable symlink `~/.dsh/source/current` points at the active staging worktree, and `dsh` in `~/.local/bin` links to `current/bin/dsh`, so an upgrade repoints one symlink and the `dsh` on PATH never moves. Re-running the command adds a fresh staging worktree from an updated master and repoints `current` at it. See [`scripts/install.sh`](scripts/install.sh) for alternate install locations and other options.\n\n## Use DeepSeek Harness\n\n### Web UI\n\nFor the recommended local interface, build the active checkout after installation and after each update, then start the Web UI:\n\n```sh\n(cd ~/.dsh/source/current && pnpm run build)\ndsh web\n```\n\nThe full build produces the library and client bundles plus the frontend dist.

The stable symlink `~/.dsh/source/current` points at the active staging worktree, and `dsh` in `~/.local/bin` links to `current/bin/dsh`, so an upgrade repoints one symlink and the `dsh` on PATH never moves. Re-running the command adds a fresh staging worktree from an updated master and repoints `current` at it. See [`scripts/install.sh`](scripts/install.sh) for alternate install locations and other options.\n\n## Use DeepSeek Harness\n\n### Web UI\n\nFor the recommended local interface, build the active checkout after installation and after each update, then start the Web UI:\n\n```sh\n(cd ~/.dsh/source/current && pnpm run build)\ndsh web\n```\n\nThe full build produces the library and client bundles plus the frontend dist.

Subject: [PATCH 232/557] test(web): refresh e2e goldens for collapsed card
 rows

The seeded-history, web-search-round, and message-actions aria goldens showed
the read/search cards inline; with the ToolRow refactor the card is collapsed
behind an expandable row button, so the goldens now record the collapsed row
shape (the card body appears only on expand, which these rounds do not click).

Subject: [PATCH 237/557] fix(web-cards): restore AT status text, guard
 file-link keys, add read docs

Address review of the ToolRow card refactor:
- ToolRow renders a visually-hidden run-state label (row.running/failed/stopped
  locale keys) so a running/failed/interrupted row is not a colour-only signal;
  the StateDot and the sweep are both aria-hidden. Restores the stopped-state
  text assertion in diff-card.spec at the ToolRow layer.
- The file-link button stops Enter/Space from bubbling to DisclosureRow's
  whole-row keydown, which would preventDefault the key and toggle expand
  instead of opening the file (the keyboard analogue of the click stopPropagation).
- search-row passes output={model.output} unconditionally, matching the other
  three card rows (ToolRow renders the card over the output when present).
- Assert locale: 'conversation' in the search/web/diff registration tests.
- Add the read render-intent paragraph to the ui-conversation README and a
  ReadBlock atom entry + Read section to ui-primitives (both languages).
- Update the grep fixture sample lines to the post-refactor SearchRow shape.
Refresh the code-mode-round, steering, and search-card goldens for the added
status text and updated sample lines.

 A tool call declaring the `web` render intent renders its web retrieval inline, at both conversation render sites, through ui-primitives' `WebBlock`. `contract/web-card-model.ts` is the single derivation from the snapshot's `resultView`, mirroring the terminal card, so the sites cannot disagree about what a web call shows; it yields null — the generic path — for a running call, a non-web result view, a generic result view, a `card` tag this client version does not know, or a web card whose `kind` this client version does not know (a newer host's value, which the wire cannot be trusted to be `search` or `fetch`). The keyed `WebRow` registers one component under both `web_search` and `web_fetch`, discriminating on the tool name only for its icon and title; it composes the shared `ToolRow`, feeding the card as ToolRow's `web` body, so the retrieval is the row's collapsed-by-default expanded card (the same unified expand every card row has). A web-declaring tool without a keyed row lands on the `GenericToolCard` fallback, which routes the card through ToolRow the same way, and the details panel renders it at the primitive's full source allowance and, below the card, the flattened model-visible result content — a fetch body is readable only there, since its card carries only the URL and status. Rows cap at `CHAT_WEB_MAX_SOURCES` (8) against the panel's 16, the same summary-versus-reading split the terminal card draws ([decision](../../../.agents/notes/implemented/feature/2026-07-30-web-result-card-frontend.md)).
 
+A `read` call declaring the `read` render intent renders the returned file window inline, at both conversation render sites, through ui-primitives' `ReadBlock` — the line-numbered, syntax-highlighted content the tool projects. `contract/read-card-model.ts` is the single derivation from the snapshot's `resultView`; the read card is result-side only (a call carries no file content until `execute` returns), so a running read shows its summary alone and it yields null — the generic path — for a non-read result view or a `card` tag this client version does not know. The keyed `ReadRow` composes the shared `ToolRow`, feeding the card as ToolRow's `read` body, so it is the row's collapsed-by-default expanded card; the summary stays a path link that opens the file through the host. The render-site fallback and the details panel are read-aware too. Rows cap at `CHAT_READ_MAX_LINES` (8) against the panel's 16 ([decision](../../../.agents/notes/implemented/feature/2026-07-30-web-read-card-frontend.md)).
+
 A tool call declaring the `diff` render intent (the `write`/`edit` tools) renders its applied change inline through ui-primitives' `DiffBlock`, the same four-layer shape. `contract/diff-card-model.ts` is the single derivation from the `callView`/`resultView` pair; the settled result's hunks replace the call-time diff, and it yields null — the generic path — for any other card tag or a generic result view (write/edit's execution errors). The keyed `FileMutationRow` (registered under both `write` and `edit`) composes the shared `ToolRow`, feeding the diff as ToolRow's `diff` body, so it is the row's collapsed-by-default expanded card; the summary path link still opens the file through the host, and an errored mutation (no diff card) surfaces its error text through ToolRow's Output section with the first line in the collapsed summary. The render-site fallback and the details panel are diff-aware too. Rows cap at `CHAT_DIFF_MAX_LINES` (8) against the panel's 16 ([decision](../../../.agents/notes/implemented/feature/2026-07-30-web-diff-card.md)).
 
 The chat flow projects consecutive model-retry nodes across retry turns into one stable, muted status row updated to the latest attempt; every retry event remains in the runtime snapshot and session log. Its frontend countdown anchors the scheduled delay to client receipt, avoiding host/browser clock skew, rounds remaining time up to seconds, and has a one-second floor. The latest unresolved retry uses a left-to-right text shimmer. Subsequent turn facts distinguish an attempt that started from one cancelled during backoff, while the Host running bit only controls the live animation; the row then shows a static completed or cancelled label. Normal policy rows show the finite retry maximum; always policy rows show `∞`. Activating the row reveals the latest exact retry delay and failure message. The client runtime removes each failed step's streaming tail before its retry node arrives, while the status remains visible after a later attempt succeeds.

 聊天流会将跨重试轮次连续出现的模型重试节点投影为一个稳定的弱化状态行，并用最新一次尝试更新该行；每个重试事件仍保留在运行时快照与会话日志中。前端倒计时以客户端收到事件的时刻为计划延迟的起点，避免 Host 与浏览器的时钟偏差；剩余时间向上取整到秒，且下限为 1 秒。最近一次尚未完成的重试会显示从左到右的文字渐变动画。后续轮次事实用于区分已开始的尝试与在退避期间取消的尝试，Host 的 running 位只控制实时动画；随后该行会显示静态的已完成或已取消标签。normal 策略行显示有限重试上限；always 策略行显示 `∞`。激活该行会显示最近一次重试的精确延迟和失败消息。客户端运行时会在相应重试节点到达前移除每个失败步骤的流式输出尾部；后续某次尝试成功后，该状态仍保持可见。

 `TerminalBlock` renders a shell command as a terminal surface: one prompt row per line of the command (the shortened `cwd` label on the first row only, since the view knows one working directory and a `cd` moves later lines elsewhere, then that line), the command's output, a status pill for a non-zero exit code or a terminating signal, and a copy control that writes the raw `output` prop. A run-state `StateDot` marks the call once, on the first row, out of flow in a gutter the card reserves as its own left padding, so the dot sits inside the card box yet left of the prompt text. It reaches three of `StateDot`'s states — the chase while `running`, red for the same exit status that renders the pill, green otherwise — so a card states whether its command is still running rather than leaving that to be inferred from the presence of output; it carries one visually hidden text label because `StateDot` is `aria-hidden`. One dot regardless of line count is deliberate: the exit status is the whole call's, so a dot per line would claim a per-line outcome the view does not carry. Command text is `white-space: pre`, so repeated spaces, tabs, and an indented continuation render verbatim while the row stays single-line and ellipsizes. ANSI escape sequences are parsed with the `anser` runtime dependency into React spans; cursor movements replay into a per-line column buffer before inert controls are stripped, since carriage return and backspace only MOVE the cursor: `100%` + CR + `OK` alone shows `OK0%`, while the `\x1b[K` a spinner writes with its redraw erases the tail so `100%\r\x1b[KOK` shows `OK`. Erase-in-line is honored in all three parameter forms, the cursor advances by terminal columns (8-column tab stops, two for emoji and CJK, none for a combining mark), and SGR state is normalized per cell as a terminal stores it, threading across lines and closing at the state the line ended in; basic-16 foreground colors map onto `--dsw-*` tokens, while 256-palette and truecolor values pass through as literal rgb. Output keeps `white-space: pre` with horizontal scrolling, so column-aligned output holds its alignment instead of soft-wrapping, and collapses to a head slice plus a tail slice past `maxLines` (default 16, the TUI transcript's split arithmetic) behind an expand button. Rationale: [the web terminal card note](../../../.agents/notes/implemented/feature/2026-07-28-web-terminal-card.md).
 
+## Read rendering
+
+`ReadBlock` renders a returned file window as a line-numbered, syntax-highlighted code surface: a bold path (or presenter-supplied title) banner with a copy control, then the content lines with their file line numbers in a gutter (a windowed read keeps the file's own numbering, so a read past an offset starts above 1). A `totalLines` exceeding the window count draws a `showing N of M` note, and the body collapses to a head slice plus a tail slice past `maxLines` (default 16, the TerminalBlock split arithmetic) behind an expand button. Highlighting runs through the same shiki path as `CodeBlock`. Rationale: [the web read card note](../../../.agents/notes/implemented/feature/2026-07-30-web-read-card.md).
+
 ## Diff rendering
 
 `DiffBlock` renders a file mutation as an inline diff surface: one bold path header per file, the removed lines (`- `, error token) above the added lines (`+ `, success token), a `⋯` gap before a same-file second hunk, and a dim `└ +A -R · N file(s)` footer. Lines are `white-space: pre` with horizontal scrolling, so a source line holds its indentation instead of soft-wrapping, and the body collapses to a head slice plus a tail slice past `maxLines` (default 16, `TerminalBlock`'s split arithmetic) behind an expand button. A create (`oldText: null`) has no removed side. The copy control writes the prefixed diff text (path headers, `- `/`+ ` lines, the gap) so a multi-file copy stays attributable, and floats in the top-right corner rather than on a banner row of its own. Geometry mirrors `CodeBlock`/`TerminalBlock`. The `+`/`-` block form mirrors the TUI transcript's diff card so a diff reads the same across front ends. Rationale: [the web diff card note](../../../.agents/notes/implemented/feature/2026-07-30-web-diff-card.md).

 `TerminalBlock` 将一条 shell 命令渲染为终端表层：命令的每一行各占一个提示行（缩短后的 `cwd` 标签只出现在第一行，因为视图只知道一个工作目录，而一个 `cd` 就会让后面的行去到别处，标签之后是该行）、命令输出、非零退出码或终止信号对应的状态胶囊，以及写入原始 `output` prop 的复制控件。一枚运行状态 `StateDot` 为整次调用标记一次，位于第一行，以脱离文档流的方式落在卡片以自身左内边距预留的落区中，因此它位于卡片盒之内、提示文字之左。它用到 `StateDot` 的三种状态——`running` 期间为追逐动画，与渲染状态胶囊相同的退出状态为红色，其余为绿色——因此卡片直接陈述其命令是否仍在运行，而不是让人从有无输出中推断；由于 `StateDot` 是 `aria-hidden`，它携带一处视觉隐藏的文本标签。无论多少行都只有一枚状态点是有意为之：退出状态属于整次调用，因此每行一枚就会声称一个视图并不携带的逐行结果。命令文本使用 `white-space: pre`，因此重复空格、制表符与缩进续行都原样呈现，同时该行仍保持单行并以省略号截断。ANSI 转义序列通过运行时依赖 `anser` 解析为 React span；光标移动在剥除无显示意义控制符之前先重放进逐行的列缓冲，因为回车与退格**只移动**光标：单是 `100%` 加回车再加 `OK` 显示为 `OK0%`，而 spinner 随重绘写出的 `\x1b[K` 会擦掉尾巴，因此 `100%\r\x1b[KOK` 显示为 `OK`。行内擦除的三种参数形式都被遵循，光标按终端列推进（8 列制表位；emoji 与 CJK 占两列；组合标记不占列），SGR 状态按单元格归一化存储，与终端一致，并跨行延续、在行结束时的状态处收束；基础 16 色前景色映射到 `--dsw-*` token，而 256 色板与真彩色值按字面 rgb 透传。输出保持 `white-space: pre` 并支持横向滚动，因此按列对齐的输出保留其对齐而不会软换行；超过 `maxLines`（默认 16，与 TUI 转录相同的切分算法）时折叠为头部切片加尾部切片，由展开按钮控制。原理：[Web 终端卡片笔记](../../../.agents/notes/implemented/feature/2026-07-28-web-terminal-card.md)。
 
+## Read 渲染

+`ReadBlock` 将返回的文件窗口渲染为带行号、语法高亮的代码表层：一个粗体路径（或 presenter 提供的标题）横幅加复制控件，其下是内容行，行号槽里是文件自身的行号（窗口化的 read 保留文件本身的编号，因此偏移之后的 read 从大于 1 处起始）。`totalLines` 超过窗口行数时画出 `showing N of M` 提示；超过 `maxLines`（默认 16，与 TerminalBlock 相同的切分算法）时折叠为头部切片加尾部切片，由展开按钮控制。高亮走与 `CodeBlock` 相同的 shiki 路径。原理：[Web read 卡片笔记](../../../.agents/notes/implemented/feature/2026-07-30-web-read-card.md)。

 ## Diff 渲染
 
 `DiffBlock` 将一次文件改动渲染为内联 diff 表层：每个文件一个粗体路径头、删除行（`- `，error token）在新增行（`+ `，success token）之上、同文件第二个 hunk 前一个 `⋯` gap，以及暗色 `└ +A -R · N file(s)` 页脚。各行使用 `white-space: pre` 并横向滚动，因此源码行保留其缩进而不软换行；超过 `maxLines`（默认 16，与 `TerminalBlock` 相同的切分算法）时折叠为头部切片加尾部切片，由展开按钮控制。新建（`oldText: null`）没有删除侧。复制控件写入带前缀的 diff 文本（路径头、`- `/`+ ` 行、gap），使多文件复制保持可归属，并浮在右上角而非占据自己的 banner 行。几何镜像 `CodeBlock`/`TerminalBlock`。`+`/`-` 块形式镜像 TUI 转录的 diff 卡片，使 diff 在两个前端读起来一致。原理：[Web diff 卡片笔记](../../../.agents/notes/implemented/feature/2026-07-30-web-diff-card.md)。

Subject: [PATCH 242/557] feat(cli): even out the shipped tool rosters across
 both surfaces
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The two shipped surfaces offered different tools for no recorded reason:
session checkpoints, tool-result pruning, the goal tools, and Ralph were in
`tui.cordis.yml`; `tool-todo` and web search were in `web.cordis.yml`. Neither
offered session search, a string-replacement editor, or a repeat-tool guard,
though none of the three is surface-specific.

Move the rows that are not surface-specific into `base.cordis.yml` and add
those three. Web search moves there too — the TUI decision the change that
made it a Web default deferred. Both surfaces now assemble the same 27 tools.

This adds only. No row is removed from either surface and no existing row's
configuration is edited: executors, sandbox composition, access defaults,
`tools.mode`, and the workflow tool are exactly what they were. Two rows stay
surface-specific: `tmux-context` (no terminal multiplexer in a browser) and
`session-reference` (its index has one writer owner).

Ship `dsh-mcp-client` as a dependency without a row: the plugin mounts one
server per instance and `command` is required, so a default would name a
third-party server and spawn it outside `ctx.bash` on every launch. The CLI
README carries the YAML for mounting one from a personal config.

+# Agent Note: Even out the shipped tool rosters
+
+Status: implemented
+
+English | [中文](2026-07-31-even-out-shipped-tool-rosters.zh.md)
+
+## Problem
+
+The two shipped `dsh` surfaces offered different tools for no recorded reason. Session checkpoints, tool-result pruning, the goal tools, and Ralph were in `tui.cordis.yml`; `tool-todo` and, later, web search were in `web.cordis.yml`. Neither surface offered session search, a string-replacement editor, or a repeat-tool guard, though all three exist as packages and none is surface-specific.
+
+The result was a user-visible difference nobody had decided: the same model, asked the same thing, could set a goal on the terminal but not in the browser, and could search the web in the browser but not on the terminal.
+
+## Decision
+
+The rows that are not surface-specific move into [`base.cordis.yml`](../../../../apps/cli/config/base.cordis.yml), and three more join them: `tool-session-query`, `tool-str-replace-editor`, and `repeat-tool-guard`. Web search moves there too, which is the TUI decision that the change making it a Web default explicitly deferred. Both surfaces now assemble the same twenty-seven tools.
+
+Two rows stay surface-specific. `tmux-context` is TUI-only because a browser surface has no terminal multiplexer to describe. `session-reference` is TUI-only because it drives the shared session-query index from the launcher's process-local path, and the browser sidebar reconciles that index on its own first search.
+
+**This change adds only.** No row is removed from either surface and no existing row's configuration is edited: the executors, the sandbox composition, the access defaults, `tools.mode`, and the workflow tool are exactly what they were. A reader comparing the two catalogs before and after should find additions and nothing else.
+
+### What stays unmounted, and why
+
+Three capabilities stay out on the evidence their own packages record, and are listed here so "we forgot" and "we decided against" stay distinguishable.
+
+**`dsh-tool-cordis`** lets the model write JavaScript and mount it as a temporary plugin. Its README states the limit: "The sandbox is containment for honest code, not a security boundary — host-realm helpers on the sandbox global are reachable, so mount code can reach Node" ([Known limitations](../../../../packages/cordis/tool-cordis/README.md)). The `node:vm` realm lives inside the harness process while `dsh-sandbox-local` confines only the argv it spawns, so on the Web surface both the sandbox and the approval seam are bypassed rather than enforced.
+
+**`dsh-web-fetch-local`** stays unmounted and `dsh-tool-web` keeps `fetch: false`. SSRF protection is deferred in the implementation ([`policy.ts`](../../../../packages/web/web-fetch-local/src/policy.ts) validates protocol, credentials, and length only) and the package says so: "this provider is an SSRF primitive and **must not be enabled** in a deployment that can reach sensitive internal network targets" ([README](../../../../packages/web/web-fetch-local/README.md)). The model chooses the target, which includes the harness's own gateway on loopback, private ranges, and cloud metadata endpoints.
+
+Withholding it narrows the surface without removing the reach: `bash` is mounted, so `curl` gets the same page, as a live run confirmed. What the absence buys is the removal of an argument-shaped request primitive that needs no shell — and with it the accidental path where a summarization request quietly reaches loopback. A deployment that must contain outbound traffic needs a network-level control.
+
+**The LSP trio** stays out for an operational reason rather than a security one: `command` resolves from `PATH` at plugin load, so a missing language server fails the whole boot rather than one tool. It becomes mountable once absence degrades to a skipped registration.
+
+### MCP is a dependency, not a row
+
+`@deepseek-ai/dsh-mcp-client` becomes a runtime dependency of the CLI without a row in any shipped config. The plugin mounts exactly one server per instance and `command` is required, so a default would have to name a third-party server and spawn it as a child process on every launch — outside `ctx.bash`, and therefore outside the sandbox policy the Web surface composes.
+
+The layer that would make MCP a default is the one this repository does not have yet: a bridge that reads a user's server list and mounts one client per entry, the same shape [`dsh-hooks-claude`](../../../../packages/hooks/hooks-claude/README.md) already has for a Claude Code `hooks.json`. Shipping the dependency means an installed `dsh` can mount servers from `$DSH_HOME/config.yaml` today; the CLI README carries the YAML.
+
+## Testing
+
+[`apps/cli/tests/shipped-composition.e2e.ts`](../../../../apps/cli/tests/shipped-composition.e2e.ts) boots the shipped tree through the real Loader in a pseudo-terminal and reads the tool names out of the `request/header` the session log persisted, so the assertion is the catalog the model was actually sent. Its `--config` overlay, [`composition-keyless-tail.cordis.yml`](../../../../apps/cli/tests/fixtures/composition-keyless-tail.cordis.yml), is test isolation only: a network-free adapter and workspace-local session artifacts.
+
+That tail also inserts [`composition-settled.ts`](../../../../apps/cli/tests/fixtures/composition-settled.ts), which announces settled Loader activation on the terminal stream. The TUI renders as soon as its own fiber starts, so a prompt typed at the banner can reach the loop while tool rows and persistence are still activating and assemble a partial catalog; gating the smoke's first prompt on that marker is what makes the assertion deterministic.
+
+The same smoke pins the TUI's unchanged execution posture from the same artifact: `tool-bash` emits its `sandbox_permissions` escalation pair only when the mounted executor has wider modes to escalate to, so asserting its **absence** fails if a later change quietly sandboxes this surface.
+
+[`apps/web/tests/shipped-composition.e2e.ts`](../../../../apps/web/tests/shipped-composition.e2e.ts) covers the Web surface in the built lane, asserting its catalog, that its access default is untouched, and that `workspace-write`'s writable roots include the temp directories — a trap that makes sandbox tests lie when the workspace sits under `/tmp` ([`roots.ts`](../../../../packages/sandbox/sandbox/src/roots.ts)).
+
+`glob` and `grep` are asserted as an all-or-nothing pair rather than fixed members: `dsh-tool-fs-search` probes `command -v rg` at load and registers neither tool without ripgrep, which is a host dependency.
+
+Beyond the committed tests, both surfaces were driven against a real key from the built `apps/cli/lib/bin.js` under plain Node. Every mounted tool executed successfully, including `ralph` and `web_search`; the model never reached `cordis_*` or `mcp_*`, fell back to `grep` when asked for LSP navigation, and used a background `bash` task when asked for a persistent terminal.
+
+## Alternatives considered
+
+**Duplicate the shared rows into both overlays instead of promoting them.** Rejected on the one-home rule: three of the new rows would exist twice with no reason for the copies to diverge, and the next roster change would have to remember both.
+
+**Sandbox the TUI in the same change.** The TUI mounts unrestricted executors, which is a real gap, and an earlier revision of this change closed it by moving the confined stack into the base. Rejected as a separate decision that does not belong in a roster change: it alters what an existing surface does rather than what it offers, and it needs its own evidence — not least because the TUI has no `approval/request` answerer, so an escalation there fails closed instead of prompting.
+
+**Enable Code Mode.** Its trust posture is bash-equivalent by design and its tool calls pass the same `tools/pre-execute` gate as bash, so it is not the same call as the model-code tools above. Rejected here anyway: `both` changes every model-visible request on both surfaces, and `code` replaces the wire rather than adding to it — either is a presentation decision, not a roster one.
+
+**Mount an MCP server by default.** Rejected because a shipped default would have to name one, and any choice spawns a third-party child process on every user's machine outside the sandbox. The dependency ships instead.
+
+## Consequences
+
+The same model gets the same tools on both surfaces, and the difference that existed for no recorded reason is gone. Twenty-seven names, asserted exactly and identically on both sides, so a later change that adds a tool to one surface only — or drops one from either — fails a check instead of shipping quietly.
+
+`apps/cli` gains five workspace dependencies: four the shipped tree now mounts, plus `dsh-mcp-client`, which it does not mount and which exists so an installed `dsh` can.
+
+Nothing about execution changed. The TUI still runs the model's commands through unrestricted executors with no approval seam, and the Web surface still defaults to `danger-full-access`. Both are pinned by assertions in this change, which makes them visible rather than fixed — the sandbox decision is still open.

+# Agent Note: 拉平交付的工具清单
+
+Status: implemented
+
+[English](2026-07-31-even-out-shipped-tool-rosters.md) | 中文
+
+## 问题
+
+两个交付的 `dsh` surface 提供着不同的工具,而没有任何记录说明为什么。会话检查点、工具结果裁剪、goal 工具和 Ralph 在 `tui.cordis.yml`;`tool-todo` 以及后来的 web 搜索在 `web.cordis.yml`。两个 surface 都没有会话搜索、字符串替换编辑器和重复工具守卫,尽管这三者都已成包存在,且没有一个是 surface 专属的。
+
+结果是一处没人做过决定的用户可见差异:同一个模型、同一个请求,在终端上能定目标而在浏览器里不能,在浏览器里能搜网页而在终端上不能。
+
+## 决策
+
+那些并非 surface 专属的行移入 [`base.cordis.yml`](../../../../apps/cli/config/base.cordis.yml),另有三行加入:`tool-session-query`、`tool-str-replace-editor` 和 `repeat-tool-guard`。Web 搜索也一并移入,这正是把它做成 Web 默认的那次改动明确推迟的 TUI 决定。两个 surface 现在组装出同样的二十七个工具。
+
+有两行仍是 surface 专属。`tmux-context` 只在 TUI,因为浏览器 surface 没有终端复用器可描述。`session-reference` 只在 TUI,因为它以 launcher 的进程本地路径驱动共享的 session-query 索引,而浏览器侧边栏会在自己的首次搜索里重建该索引。
+
+**本次改动只做加法。** 两个 surface 都没有任何一行被移除,也没有任何既有行的配置被编辑:执行器、沙箱组合、访问默认值、`tools.mode` 以及 workflow 工具,全都保持原样。对比改动前后的两份目录,读者应当只看到新增,别无其他。
+
+### 什么保持不挂,以及为什么
+
+有三项能力基于其自身包所记录的证据保持在外,列在这里是为了让「我们忘了」和「我们决定不要」保持可区分。
+
+**`dsh-tool-cordis`** 让模型写一段 JavaScript 并挂成临时插件。它的 README 写明了这个界限:「The sandbox is containment for honest code, not a security boundary — host-realm helpers on the sandbox global are reachable, so mount code can reach Node」([Known limitations](../../../../packages/cordis/tool-cordis/README.md))。`node:vm` 的 realm 就在 harness 进程内,而 `dsh-sandbox-local` 只约束它 spawn 出去的 argv,因此在 Web surface 上,沙箱与批准接缝是被绕过而非被执行。
+
+**`dsh-web-fetch-local`** 保持不挂,`dsh-tool-web` 保持 `fetch: false`。SSRF 防护在实现中是 deferred 状态([`policy.ts`](../../../../packages/web/web-fetch-local/src/policy.ts) 只校验协议、凭据与长度),包里也直说了:「this provider is an SSRF primitive and **must not be enabled** in a deployment that can reach sensitive internal network targets」([README](../../../../packages/web/web-fetch-local/README.md))。目标由模型选择,其中包括 harness 自己跑在环回地址上的网关、内网段和云元数据端点。
+
+弃用它收窄的是接触面而非可达性:`bash` 是挂着的,`curl` 照样能拿到同一个页面——一次真实运行确认了这点。这个缺席买到的是去掉一个无需 shell、以参数成形的请求原语,以及随之而来的那条意外路径:一次「帮我总结这个页面」悄悄打到环回地址。真要收住出站流量的部署需要的是网络层管控。
+
+**LSP 三件套**留在外面是运维原因而非安全原因:`command` 在插件加载时从 `PATH` 解析,因此缺少语言服务器会让整次启动失败,而不只是失去一个工具。等到「缺失」退化为「跳过注册」之后,它就可以挂了。
+
+### MCP 是依赖,不是配置行
+
+`@deepseek-ai/dsh-mcp-client` 成为本 CLI 的运行时依赖,但在任何交付配置里都没有对应的行。该插件每个实例只挂载一台服务器,且 `command` 是必填,因此一个默认值必须点名一台第三方服务器,并在每次启动时把它作为子进程 spawn——不经 `ctx.bash`,因而也在 Web surface 所组合的沙箱策略之外。
+
+真正能让 MCP 成为默认的那一层,恰恰是本仓库尚未拥有的:一个读取用户服务器清单、按条目逐台挂载客户端的桥接,形态与 [`dsh-hooks-claude`](../../../../packages/hooks/hooks-claude/README.md) 读取 Claude Code 的 `hooks.json` 完全相同。交付这个依赖意味着已安装的 `dsh` 今天就能从 `$DSH_HOME/config.yaml` 挂载服务器;CLI README 里给了那段 YAML。
+
+## 测试
+
+[`apps/cli/tests/shipped-composition.e2e.ts`](../../../../apps/cli/tests/shipped-composition.e2e.ts) 在伪终端中通过真实 Loader 启动交付树,并从会话日志持久化的 `request/header` 中读出工具名,因此断言的正是模型实际收到的目录。它传入的 `--config` overlay [`composition-keyless-tail.cordis.yml`](../../../../apps/cli/tests/fixtures/composition-keyless-tail.cordis.yml) 只做测试隔离:一个无网络适配器,以及落在工作区内的会话产物。
+
+该尾部还插入了 [`composition-settled.ts`](../../../../apps/cli/tests/fixtures/composition-settled.ts),它在终端字节流上宣告 Loader 激活已 settle。TUI 在自己的 fiber 一启动就渲染,因此在 banner 处敲下的提示词可能在工具行与持久化仍在激活时就抵达循环,从而组装出不完整的目录;把冒烟的首个提示词 gate 在该标记上,正是断言得以确定的原因。
+
+同一份冒烟还从同一份产物上钉住 TUI 未改变的执行姿态:`tool-bash` 只在挂载的执行器确实有更宽模式可升级时才发出 `sandbox_permissions` 升级参数对,因此断言它的**缺席**会在日后有人悄悄给这个 surface 加上沙箱时失败。
+
+[`apps/web/tests/shipped-composition.e2e.ts`](../../../../apps/web/tests/shipped-composition.e2e.ts) 在构建产物 lane 中覆盖 Web surface,断言它的工具目录、它的访问默认值未被触碰,以及 `workspace-write` 的可写根包含临时目录——一个会让沙箱测试说谎的陷阱,当工作区落在 `/tmp` 下时([`roots.ts`](../../../../packages/sandbox/sandbox/src/roots.ts))。
+
+`glob` 与 `grep` 被作为全有或全无的一对断言,而不是固定成员:`dsh-tool-fs-search` 在加载时探测 `command -v rg`,没有 ripgrep 就两个工具都不注册,这是宿主依赖。
+
+除入库测试外,两个 surface 都以 plain Node 从构建产物 `apps/cli/lib/bin.js` 出发、用真实密钥驱动过。每一个已挂载的工具都执行成功,包括 `ralph` 与 `web_search`;模型从未触达 `cordis_*` 或 `mcp_*`,被要求做 LSP 跳转时退化到 `grep`,被要求开持久终端时用了后台 `bash` 任务。
+
+## 曾考虑的替代方案
+
+**把共享的行复制进两份 overlay,而不是提升到 base。** 基于「一处归属」原则否决:新增行里有三行会存在两份,而这些副本没有任何理由发生分歧,下一次改工具清单还得记着改两处。
+
+**在同一次改动里给 TUI 加沙箱。** TUI 挂的是不受限执行器,这确实是个真实缺口,本次改动的早先一版曾把受限栈移入 base 来堵上它。作为一个不属于工具清单改动的独立决定被否决:它改变的是一个既有 surface 的行为而非它提供的东西,而且需要它自己的证据——尤其因为 TUI 没有 `approval/request` 的应答方,升级请求在那里是 fail-closed 而不是弹出提示。
+
+**开启 Code Mode。** 它的信任立场按设计与 bash 同级,工具调用要过与 bash 相同的 `tools/pre-execute` 闸门,所以它与上面那些模型写码工具不是同一个判断。在这里仍被否决:`both` 会改变两个 surface 上每一个模型可见请求,而 `code` 是把线路替换而非加一个——两者都是呈现方式的决定,不是工具清单的决定。
+
+**默认挂一台 MCP 服务器。** 否决,因为交付默认值必须点名一台,而任何选择都会在每个用户的机器上、在沙箱之外 spawn 一个第三方子进程。改为交付依赖。
+
+## 后果
+
+同一个模型在两个 surface 上拿到同样的工具,那处没有记录理由的差异消失了。二十七个名字,两侧精确且一致地断言,因此日后只给一个 surface 加工具、或从任一侧丢掉工具,都会让检查失败而不是悄悄发出去。
+
+`apps/cli` 增加五个 workspace 依赖:四个是交付树现在挂载的,外加 `dsh-mcp-client`——它并不被挂载,存在的意义是让已安装的 `dsh` 能挂。
+
+执行相关的一切都没有变。TUI 仍以不受限执行器运行模型的命令且没有批准接缝,Web surface 仍默认 `danger-full-access`。两者都由本次改动中的断言钉住,这让它们变得可见而非被修复——沙箱那个决定仍然悬着。

-`DSH_TOOLS_MODE` selects the tool presentation mode for the whole Web/headless process: `native` (the schema default when unset), `code` (the `run_code`-only Code Mode wire), or `both`; any other value fails loud at boot through the `dsh-tools` config schema. It is a TEMPORARY seam — process-wide because Loader composition is static — and is removed once the web UI owns per-session tool-mode selection; the TUI surface ignores it (its config tree pins its own mode).
+Every surface presents tools in `both` mode: the model receives every native schema **and** the Code Mode `run_code` transport, so a task that would be a long tool-call chain can be one program instead. Code Mode's trust posture is bash-equivalent by design — model code reaches Node APIs, but its tool calls pass the same `tools/pre-execute` gate as bash, and the worker adds containment bash has no equivalent for (a separate isolate, an empty environment, a heap cap, and hard termination). `DSH_TOOLS_MODE` overrides the presentation for a whole Web/headless process — `native` drops `run_code`, `code` sends only it — and any other value fails loud at boot through the `dsh-tools` config schema. It is a TEMPORARY seam, process-wide because Loader composition is static, removed once the web UI owns per-session tool-mode selection; the TUI surface ignores it (its config tree pins its own mode).
 
 Every `dsh` surface — TUI, Web, and headless — reports session telemetry by default (the row lives in the shared `base.cordis.yml`): every session-log event streams as OTLP/HTTP log records to `https://harness-telemetry.deepseeksvc.com/v1/logs` on a 10-second batch cadence. `DSH_TELEMETRY_OTLP_URL` points the exporter at a different collector; setting `DSH_TELEMETRY_DISABLED` to ANY non-empty value — including `0` or `false` — disables the row before it loads (a privacy switch prefers off-by-mistake over on-by-mistake). No redaction rule is mounted in this composition yet: exported records are the raw captured copy, including message text, tool arguments and results, and the session's working-directory path. The deployment rulings live in the [web-telemetry-default-mount Agent Note](../../.agents/notes/implemented/feature/2026-07-31-web-telemetry-default-mount.md).
 
+MCP servers are not a shipped default, because a default would have to name one: `@deepseek-ai/dsh-mcp-client` mounts exactly one server per row and spawns it as a child process, outside `ctx.bash` and so outside the sandbox policy. The package is a runtime dependency of this CLI, so an installed `dsh` can mount your own servers from `$DSH_HOME/config.yaml` or a `--config` overlay without a source checkout:
+
+```yaml
+- insert:
+    - id: mcp-github
+      name: '@deepseek-ai/dsh-mcp-client'
+      config:
+        serverName: github
+        transport: stdio
+        command: npx
+        args: ['-y', '@modelcontextprotocol/server-github']
+        env:
+          GITHUB_TOKEN: !!js process.env.GITHUB_TOKEN
+```
+
+The model then sees `mcp__github__*`. See the [mcp-client README](../../packages/mcp/mcp-client/README.md) for the Streamable HTTP transport and the full field table.
+
 ## Install (developer machine)
 
 Symlink the source-running launcher onto your PATH; it resolves the checkout through its own real path, so code changes apply on the next launch with no build step:

 已交付的 TUI 和 Web 组合会注册原生 DeepSeek 适配器，以及 pi-ai 的 OpenAI 和 Anthropic 提供方配置。凭据和端点覆盖来自启动分层环境中的提供方标准变量对：`DEEPSEEK_API_KEY` / `DEEPSEEK_BASE_URL`、`OPENAI_API_KEY` / `OPENAI_BASE_URL` 和 `ANTHROPIC_API_KEY` / `ANTHROPIC_BASE_URL`。
 
-Web／无头组合还只会注册 `web_search`。搜索使用 DeepSeek 的 Anthropic 兼容 Messages 端点，每次调用都会解析同一个 `DEEPSEEK_API_KEY` 凭据引用，并接受独立的 `DEEPSEEK_SEARCH_BASE_URL` 端点覆盖；每次搜索都是一次辅助模型请求，会产生独立的延迟与 token 成本。`web_fetch` 仍处于禁用状态，组合也未挂载默认抓取提供方；需要任意页面抓取能力的部署必须通过覆盖层选择启用。TUI 组合默认不挂载 Web 工具。部署决策及其安全边界见[默认 Web 搜索 Agent Note](../../.agents/notes/implemented/feature/2026-07-31-web-default-search.md)。
+每个界面也都只注册 `web_search` 这一个 Web 工具。搜索使用 DeepSeek 的 Anthropic 兼容 Messages 端点，每次调用都会解析同一个 `DEEPSEEK_API_KEY` 凭据引用，并接受独立的 `DEEPSEEK_SEARCH_BASE_URL` 端点覆盖；每次搜索都是一次辅助模型请求，会产生独立的延迟与 token 成本。`web_fetch` 仍处于禁用状态，组合也未挂载默认抓取提供方；需要任意页面抓取能力的部署必须通过覆盖层选择启用。部署决策及其安全边界见[默认 Web 搜索 Agent Note](../../.agents/notes/implemented/feature/2026-07-31-web-default-search.md)。
 
-`DSH_TOOLS_MODE` 为整个 Web／无头进程选择工具呈现模式：可选值为 `native`（未设置时的 schema 默认值）、`code`（仅含 `run_code` 的 Code Mode 协议接口）或 `both`；任何其他值都会经由 `dsh-tools` 配置 schema 在启动时明确报错。它是一个临时 seam：Loader 组合是静态的，因此该设置作用于整个进程；待 Web UI 负责逐会话工具模式选择后便会移除。TUI 界面会忽略该变量（其配置树固定了自身模式）。
+每个界面都以 `both` 模式呈现工具:模型同时收到全部原生 schema **和** Code Mode 的 `run_code` 传输通道,于是原本要一长串工具调用的任务可以写成一段程序。Code Mode 的信任立场按设计与 bash 同级——模型代码可以触达 Node API,但它的工具调用要过与 bash 相同的 `tools/pre-execute` 闸门,而该 worker 还提供了 bash 没有的收容(独立 isolate、空环境、堆上限、硬终止)。`DSH_TOOLS_MODE` 可为整个 Web／无头进程覆盖呈现模式——`native` 去掉 `run_code`,`code` 则只发它——任何其他值都会经由 `dsh-tools` 配置 schema 在启动时明确报错。它是一个临时 seam:Loader 组合是静态的,因此该设置作用于整个进程;待 Web UI 负责逐会话工具模式选择后便会移除。TUI 界面会忽略该变量(其配置树固定了自身模式)。
 
 每个 `dsh` 界面——TUI、Web 与无头——都默认上报会话遥测（该行位于共享的 `base.cordis.yml`）：每条会话日志事件以 OTLP/HTTP 日志记录的形式、按 10 秒批处理节奏流向 `https://harness-telemetry.deepseeksvc.com/v1/logs`。`DSH_TELEMETRY_OTLP_URL` 可将 exporter 指向其他 collector；将 `DSH_TELEMETRY_DISABLED` 设为**任意非空值**——包括 `0` 或 `false`——都会在该行加载前将其关停（隐私开关取「宁可误关、不可误开」）。该组合当前未挂载任何脱敏规则：导出记录即原始捕获副本，包含消息正文、工具参数与结果、以及会话工作目录路径。部署口径见 [web-telemetry-default-mount Agent Note](../../.agents/notes/implemented/feature/2026-07-31-web-telemetry-default-mount.md)。
 
+MCP 服务器不是交付默认值,因为默认值必须点名一台:`@deepseek-ai/dsh-mcp-client` 每一行只挂载一台服务器,并把它作为子进程 spawn,该进程不经 `ctx.bash`,因此也不受沙箱策略约束。该包是本 CLI 的运行时依赖,所以已安装的 `dsh` 无需源码检出即可从 `$DSH_HOME/config.yaml` 或 `--config` 覆盖层挂载你自己的服务器:
+
+```yaml
+- insert:
+    - id: mcp-github
+      name: '@deepseek-ai/dsh-mcp-client'
+      config:
+        serverName: github
+        transport: stdio

+        env:
+          GITHUB_TOKEN: !!js process.env.GITHUB_TOKEN
+```
+
+模型随后会看到 `mcp__github__*`。Streamable HTTP 传输与完整字段表见 [mcp-client README](../../packages/mcp/mcp-client/README.md)。

Subject: [PATCH 243/557] fix(ui-conversation): keep hero visible while a blank
 session opens

A summary-proven blank session can only land back on the hero, so the
settling phase (visibility:hidden composer seat) blanked the center
column for the whole history round-trip during startup auto-selection.
Exempt such sessions from settling and treat them as hero while loading.

-The official `dsh` launcher owns one versioned acknowledgement marker under the resolved `DSH_HOME`. It checks the immutable marker before boot, then mounts an effect-owned consumer of `ctx.tui.openOverlay()` only after the real TUI service is available. Enter is the sole acknowledgement action: the plugin creates and synchronizes the fixed per-version marker before closing. Escape and every other non-navigation input leave the overlay open; disposal or process exit before Enter writes nothing. The version is part of the marker filename, so incrementing the centrally owned notice version presents materially revised copy once without migrating or rewriting an aggregate settings document.

The version is part of the marker filename, so incrementing the centrally owned notice version presents materially revised copy once without migrating or rewriting an aggregate settings document.
 
 The marker is launcher state rather than session persistence because eligibility spans sessions and workspaces but is scoped to one Harness home. Each Enter syncs a random same-directory file before atomically replacing the fixed marker; concurrent launches publish the same immutable fact, so same-value last-writer-wins replacement has no lost-update shape and needs no lock or dependency on the settings stack. The notice never appends a session event, injects model context, or creates a user turn; resume therefore presents it only when the same Harness home has not acknowledged that version and never replays it from the session log.

+官方 `dsh` 启动器在解析后的 `DSH_HOME` 下持有一个版本化确认标记。它会在启动前检查该不可变标记，并仅在真实 TUI 服务可用后，挂载一个由 effect 持有的 `ctx.tui.openOverlay()` 消费方。Enter 是唯一确认操作：插件先创建并同步固定的逐版本标记，再关闭浮层。Escape 和无法识别的输入会让浮层保持打开；Ctrl+C 与 Ctrl+D 通过普通退出路径离开且不确认。资源释放会等待已经由 Enter 启动的确认任务；在按 Enter 前进行资源释放或退出进程不会写入任何内容。版本号属于标记文件名的一部分，因此只需递增集中持有的通知版本，即可让有实质修改的文案重新展示一次，无需迁移或改写聚合设置文档。
 
 该标记属于启动器状态，而非会话持久化，因为展示资格跨越会话与 workspace，但作用域仅限一个 Harness 主目录。每次 Enter 都会先同步一个同目录随机文件，再以原子方式替换固定标记；并发启动发布的是同一个不可变事实，因此同值的最后写入者胜出不会丢失更新，也无需加锁或依赖设置栈。该通知绝不追加会话事件、注入模型上下文或创建用户轮次；因此，恢复会话只会在同一个 Harness 主目录尚未确认该版本时展示通知，也绝不会从会话日志中回放通知。

 This package owns interactive terminal presentation and input only. It injects `agents`, [`commands`](../commands/README.md), `llm`, `systemPrompt`, `tokenMeter`, `tools`, and `userInteraction`, optionally reads a `skills` service (present only when one is mounted), then drives an agent created or resumed by app or developer code. Agent lifecycle, persistence, and the model-facing [`ask_user_question`](../tool-ask-user/README.md) tool remain separate composition entries.
 
-After terminal startup succeeds, the package provides the terminal-local `ctx.tui` extension service. A plugin that injects it can call `openOverlay()` with a component factory and constrained layout options; the host exposes the viewport, semantic theme (including terminal-safe DeepSeek `brand` treatment), display-text escaping, redraw, close, and a lifetime signal, but not the pi-tui tree, terminal, focus controller, or overlay handle. The package exports semantic-key, ANSI-wrap, truncation, and visible-width primitives for extension components, keeping the underlying renderer dependency inside `dsh-tui`. Plugin overlays, the model selector, and user questions share one FIFO modal queue. Each request is an effect of the calling plugin fiber, so unload removes queued work or closes visible work before cleanup settles; terminal shutdown unloads dependents before stopping pi-tui. Overlay state is not logged or replayed. Component code is trusted and may render ANSI styling, but must pass untrusted text through `host.display()`. The [interactive-extension Agent Note](../../../.agents/notes/implemented/architecture/2026-07-22-tui-interactive-extension-service.md) owns the boundary and rejected alternatives.

 The TUI rebuilds resumed history from the append-origin session events, renders Markdown responses and reasoning, applies each tool's `presentCall` / `presentResult` intent to terminal, diff, or generic cards, keeps the standing `todo/write` plan above the editor (cleared on the next `turn/start`), and presents `ctx.userInteraction` questions in a wide bottom-left keyboard panel with progress, numbered options, and aligned descriptions. The latest logged session title becomes the header subtitle, with `welcome` before a title exists, and the terminal window title becomes ` — `. A durable `llm/retry` event retracts the failed step's live chunks and renders the scheduled retry count, delay, and failure in the transcript; success, exhaustion, and cancellation then settle through ordinary session events. The footer totals each logged model step's usage once, including failed attempts, while treating committed-message usage as a fallback for logs without a usage chunk. Its idle view compares token-meter pressure with `ctx.llm.resolveModelInfo()` context for the current route, displays `context unknown` when the adapter has no capacity metadata, and also shows tool-card mode plus the current model and any explicitly selected reasoning effort; while the agent runs, an elapsed working indicator and `esc interrupt` replace that summary. A surface replacement never rewrites the rendered transcript: the conversation it shadows stays readable, and a landed compaction checkpoint adds one dim `… earlier context was compacted …` marker at its log position, so the terminal reports where the model stopped seeing that history instead of erasing it. Model-only replacement copies — a pruned tool result, a regenerated assistant message — render nothing.

+# Agent Note: Hero stays visible while a blank session opens
+
+Status: implemented
+
+English | [中文](2026-07-31-hero-visible-while-blank-session-opens.zh.md)
+
+## Problem
+
+The conversation root has a `settling` phase for a session that is still opening while its composer reads `blank`: the hero-versus-docked outcome is unknowable until history arrives, so the composer seat is hidden (`visibility:hidden`) rather than flashing the centered hero and snapping to the docked bar. Startup auto-selection turned that guard into the defect it was meant to prevent. From the no-workspace hero, `WorkspacesService.startInitialSelection` connects the most recent workspace and opens its blank session; `openState` flips to `loading` the moment `open()` lands, so the center column went blank for the whole history round-trip and then repainted, which reads as a full-page refresh on every launch.
+
+## Decision
+
+`ConversationRoot` reads the session list summary's `blank` flag alongside the conversation snapshot and exempts summary-proven blank sessions from settling: `settling` additionally requires `summaryBlank !== true`, and `hero` accepts a blank composer while `openState === 'loading'` when the summary proves the session blank. A session the list already reports as blank can only land on the hero, so hiding buys nothing and costs the visible flash. When the summary row is absent — a session not yet listed — `summaryBlank` is `undefined` and the conservative settling hide is unchanged.
+
+The summary flag and the snapshot's own `blank` are distinct sources: the snapshot describes the session being opened, the summary is the list row that already exists before the open resolves. Only the latter is available early enough to decide the phase.
+
+## Alternatives considered
+
+**Drop the settling phase entirely.** Rejected because it still earns its keep for a session with no summary row: without a prior claim about emptiness, hero-versus-docked is genuinely unknowable and the flash it prevents is the worse one.
+
+**Delay the `loading` flip until history returns.** Rejected because `openState` is authoritative about the open operation; deferring it to suppress a presentation artifact would misreport the data state to every other consumer.
+
+**Cross-fade or otherwise animate the settling hide.** Rejected because the column has nothing to show during the round-trip either way — the fix is to not hide content whose outcome is already known, not to decorate the hiding.
+
+## Deferred
+
+The no-session→session tree relocation in `ConversationRoot` (the hero/composer subtree moves into the `conversation.session` outlet) still rebuilds the composer DOM on the same transition; removing it means moving `conversation.session` to `session-maybe` scope, a slot-contract change that needs its own proposal.
+
+Object-layer reference churn found while diagnosing this — no-op projections minting fresh snapshots, the create path projecting twice, `select()` using `notifyNow` from async continuations — is real but independent of the visible flash.
+
+## Consequences
+
+Startup auto-selection renders the hero immediately and keeps the composer seat and header visible through the history round-trip, so launching into a recent workspace no longer looks like a page reload. Sessions with no list summary keep the previous settling behavior, so the guard still covers the case it was written for. Skeleton tests pin both branches: an unlisted blank session settles, a summary-proven blank session opening under `loading` renders hero chrome and a live textarea.

+# Agent Note: 空白会话打开期间保持 hero 可见
+
+Status: implemented
+
+[English](2026-07-31-hero-visible-while-blank-session-opens.md) | 中文
+
+## 问题
+
+会话根节点为"正在打开且 composer 处于 `blank`"的会话保留了一个 `settling` 阶段：在历史记录返回之前，hero 与 docked 的归属不可知，因此宁可隐藏 composer 座位（`visibility:hidden`），也不要先闪出居中的 hero 再跳到底部输入条。启动时的自动选择把这道防护变成了它本要防止的缺陷。从无工作区的 hero 进入时，`WorkspacesService.startInitialSelection` 会连接最近的工作区并打开其空白会话；`open()` 一落地 `openState` 立即翻为 `loading`，中间栏因此在整个历史往返期间保持空白，随后重绘一次——每次启动看起来都像整页刷新。
+
+## 决策
+
+`ConversationRoot` 在读取会话快照的同时读取会话列表摘要的 `blank` 标志，并让"摘要已证明为空白"的会话豁免 settling：`settling` 额外要求 `summaryBlank !== true`，而 `hero` 在摘要证明会话为空白时，接受 `openState === 'loading'` 期间处于 blank 的 composer。列表已报告为空白的会话只可能落到 hero，因此隐藏毫无收益，只换来一次可见闪烁。当摘要行缺失时——会话尚未出现在列表中——`summaryBlank` 为 `undefined`，保守的 settling 隐藏行为保持不变。
+
+摘要标志与快照自身的 `blank` 是两个不同来源：快照描述正在打开的这个会话，摘要则是在打开操作完成之前就已存在的列表行。只有后者足够早，可用于决定阶段。
+
+## 备选方案
+
+**彻底移除 settling 阶段。** 否决，因为对没有摘要行的会话它仍有价值：在缺少任何关于"是否为空"的先验断言时，hero 与 docked 的归属确实不可知，而它所防止的那种闪烁更糟糕。
+
+**推迟 `loading` 的翻转，直到历史返回。** 否决，因为 `openState` 是打开操作的权威状态；为了压制一个呈现层瑕疵而推迟它，会向其他所有消费者误报数据状态。
+
+**为 settling 的隐藏加交叉淡入或其他动画。** 否决，因为无论如何该栏在往返期间都没有内容可展示——正确的修复是不隐藏结局已知的内容，而不是把隐藏装饰得好看些。
+
+## 推迟事项
+
+`ConversationRoot` 中"无会话→有会话"的树位置迁移（hero/composer 子树移入 `conversation.session` 出口）仍会在同一次转换中重建 composer 的 DOM；消除它意味着把 `conversation.session` 移到 `session-maybe` 作用域，这是一次插槽契约变更，需要单独立项。
+
+诊断期间发现的对象层引用抖动——空操作投影铸造出新的快照、创建路径重复投影一次、`select()` 在异步续体中使用 `notifyNow`——确实存在，但与这次可见闪烁相互独立。
+
+## 影响
+
+启动自动选择会立即渲染 hero，并在整个历史往返期间保持 composer 座位与 header 可见，因此启动进入最近工作区不再像页面重载。没有列表摘要的会话保持原有的 settling 行为，这道防护仍覆盖它当初针对的场景。骨架测试固定了两条分支：未列出的空白会话进入 settling；摘要已证明为空白的会话在 `loading` 期间渲染 hero 外壳与可用的文本框。

 A failed attempt may leave `assistant/chunk` events in its closed step, but it never appends `assistant/message` and never dispatches a tool. A retry closes the failed turn, opens the next numbered turn, reconstructs the request from the durable surface, and produces its own chunks. UIs may render live chunks while a step is open, then mark or clear that transient view when `llm/retry` identifies the failed step or `turn/end` records failure. Web validates the complete retry payload contract, clears the failed partial at `llm/retry`, projects consecutive retry-turn events into one stable row updated to the latest attempt, and derives scheduled, started, or cancelled status from subsequent turn facts. Its countdown anchors the scheduled delay to browser receipt rather than the Host event clock, uses ceiling-rounded seconds with a one-second floor, animates only while unresolved, and keeps exact latest failure details collapsed behind the row. Retry nodes anchor their own trajectory turn even when the failed attempt has no assistant node. Message derivation continues to ignore the failed chunks, and Web applies the same projection during history rebuild so refreshing cannot resurrect discarded partials or duplicate retry rows.

+If recovery is exhausted, the final failure is stored once on `turn/end.reason` with the structured facts. Web derives one `turn-error` node at that sequence position and renders its display-safe message and optional code inline; AUTH projections replace provider copy that may echo credential fragments with `API key is invalid`, while the raw diagnostic remains in the session log. The same fold runs for live events and history replay.

CI explicitly selects replay mode. The live-interactions AUTH scenario pins a non-retryable terminal failure as an inline Chat status carrying the display-safe message and code, verifies that provider-echoed credential fragments stay absent from both Chat and Trajectory, and covers composer recovery plus the `turn/end` error. The scaffold hermeticity scenario populates distinct entries in all three ambient skill roots and requires none to enter the assembled catalog. `dsh-llm-replay` unit coverage pins pacing, cancellation, consumption diagnostics, sidecar validation, indexed replacement, and the single append position.
 
 ## Deferred
 
 - **Web header-class pin**: web fixtures tokenize `{{system}}`/`{{tools}}` everywhere and no scenario pins the web composition's prompt/tool schemas (`TODO(web-header-pin)` — the scaffold `recordFixture` JSDoc marks it). Following the TUI scrub-everywhere precedent; revisit when the web assembly's header diverges from the repl composition it mirrors.
 - **Follow-up-prompt-after-resume scenario**: the history/live stitch path over the real wire; add as its own scenario when that code changes or regresses.
-- **Web error surface**: the client consumes no `agent/error` frames and a pre-chunk failure freezes no partial, so a non-retryable provider failure renders no error copy — the user sees the send simply stop. The AUTH scenario pins the current contract (no crash, composer recovers, turn logged `error`) and `FIXME(web-error-surface)` marks where visible error text gets asserted once the UI grows an error rendering.
 - **Composer steering gesture**: the input locks while running (stop-or-wait), so the steering scenario steers over the wire from the page; `TODO(web-steer-composer)` upgrades the drive step to a real composer gesture when the product grows one.
 - **Drag session reorder**: `workspace.insertSessionBefore` has no browser scenario; it needs two sessions materialized in one workspace plus synthesized HTML5 drag events. Add it when that surface changes or regresses. The inert session Rename/Fork/Delete and workspace Delete menu rows get scenarios when they gain behavior.

 ## 暂缓
 
 - **Web 头类别钉住**：web fixture 处处 token 化 `{{system}}`/`{{tools}}`，没有场景钉住 web 组合的提示词/工具 schema（`TODO(web-header-pin)`——scaffold 的 `recordFixture` JSDoc 有标记）。沿用 TUI 处处脱敏先例；当 web 组装的请求头与其镜像的 repl 组合进一步分叉时重审。
 - **恢复后追问场景**：真实 wire 上的历史/实时缝合路径；当该代码变更或回归时作为独立场景补充。
-- **Web 错误表面**：客户端不消费任何 `agent/error` 帧，分片前的失败也没有可冻结的部分输出，因此不可重试的提供方失败不渲染任何错误文案——用户看到的只是发送就此停住。AUTH 场景钉住当前契约（不崩溃、输入框恢复可用、轮次记录为 `error`），`FIXME(web-error-surface)` 标记了待 UI 长出错误渲染后断言可见错误文本的位置。
 - **输入框 steering 手势**：输入在运行期间锁定（只能停止或等待），因此 steering 场景从页面走 wire 做 steer；`TODO(web-steer-composer)` 待产品长出真实的输入框手势后，把驱动步骤升级为该手势。
 - **拖拽会话重排**：`workspace.insertSessionBefore` 尚无浏览器场景；它需要在同一个工作区里物化两个会话，并合成 HTML5 拖拽事件。当该表面变更或回归时再补充。无行为的会话 Rename/Fork/Delete 和工作区 Delete 菜单行待获得行为后再补充场景。

 ## Model retry projection
 
-The Session object validates plugin-owned, provider-routed `llm/retry` payloads at the event wire boundary against the producer's complete field contract, including timer, integer, status, provider-delay, and non-empty diagnostic bounds. A valid event removes the matching failed step's streaming partial and inserts a durable retry notice at the event's sequence position. The notice is `scheduled` until a following retry turn starts; an aborted or disposed source turn marks it `cancelled`, while the retry turn marks it `started`. Normal-mode notices carry their finite maximum; always-mode notices remain explicitly unbounded. Window rebuild and history replay apply the same projection, so logged chunks from the discarded attempt never reappear as an interrupted reply after refresh. A terminal turn without `llm/retry` retains the existing behavior: visible unfinalized output is frozen as an interrupted assistant node.

The notice is `scheduled` until a following retry turn starts; an aborted or disposed source turn marks it `cancelled`, while the retry turn marks it `started`. Normal-mode notices carry their finite maximum; always-mode notices remain explicitly unbounded. A terminal `turn/end` error without a retry projects one `turn-error` node from its durable message and optional code; AUTH projections replace provider copy that may echo credential fragments with `API key is invalid`, while the raw diagnostic remains in the session log. A retried failure keeps only the retry notice for that attempt. Window rebuild and history replay apply the same projection, so refresh neither resurrects discarded chunks nor loses terminal failure feedback. Visible unfinalized output is frozen as an interrupted assistant node beside the terminal error.

 A tool call declaring the `diff` render intent (the `write`/`edit` tools) renders its applied change inline through ui-primitives' `DiffBlock`, the same four-layer shape. `contract/diff-card-model.ts` is the single derivation from the `callView`/`resultView` pair; the settled result's hunks replace the call-time diff, and it yields null — the generic path — for any other card tag or a generic result view (write/edit's execution errors). The keyed `FileMutationRow` (registered under both `write` and `edit`) composes the shared `ToolRow`, feeding the diff as ToolRow's `diff` body, so it is the row's collapsed-by-default expanded card; the summary path link still opens the file through the host, and an errored mutation (no diff card) surfaces its error text through ToolRow's Output section with the first line in the collapsed summary. The render-site fallback and the details panel are diff-aware too. Rows cap at `CHAT_DIFF_MAX_LINES` (8) against the panel's 16 ([decision](../../../.agents/notes/implemented/feature/2026-07-30-web-diff-card.md)).
 
-The chat flow projects consecutive model-retry nodes across retry turns into one stable, muted status row updated to the latest attempt; every retry event remains in the runtime snapshot and session log. Its frontend countdown anchors the scheduled delay to client receipt, avoiding host/browser clock skew, rounds remaining time up to seconds, and has a one-second floor. The latest unresolved retry uses a left-to-right text shimmer. Subsequent turn facts distinguish an attempt that started from one cancelled during backoff, while the Host running bit only controls the live animation; the row then shows a static completed or cancelled label. Normal policy rows show the finite retry maximum; always policy rows show `∞`. Activating the row reveals the latest exact retry delay and failure message. The client runtime removes each failed step's streaming tail before its retry node arrives, while the status remains visible after a later attempt succeeds.

The client runtime removes each failed step's streaming tail before its retry node arrives, while the status remains visible after a later attempt succeeds. An unretried terminal failure renders as a persistent inline status at its turn boundary, showing the display-safe durable message and optional error code without offering an action the Host cannot fulfill; AUTH copy never echoes provider-supplied credential fragments.
 
 A `grep`/`glob` call declaring the `search` render intent renders its result inline, at the same render sites, through ui-primitives' `SearchBlock` — grep's matches grouped by file (each a collapsible header of `lineNumber: line` rows), glob's flat path list. `contract/search-card-model.ts` is the single derivation from the snapshot's `resultView`; unlike the terminal card it reads no `callView`, since a search has no matches or paths before `execute`, so a running search shows its summary alone. It yields null — the generic path — for any non-search result view, a `card` or `kind` this client version does not compile, and (because those ride the untrusted wire frame) a known kind whose `files`/`paths` is malformed. The keyed `SearchRow`, registered under both `grep` and `glob` since the derived `kind` decides the shape, composes the shared `ToolRow`, feeding the card as ToolRow's `search` body, so it is the row's collapsed-by-default expanded card; the render-site fallback routes it the same way. Both cap at `CHAT_SEARCH_MAX_LINES` (8) against the panel's 16. A capped search drops rows from the card, but the locator to the rest — grep/glob's `Full … stored at …` footer — lives only in the result text, so the derivation surfaces that as a recovery footer below the card when (and only when) the result was truncated; a settled call with no card at all (an errored search, a nested `run_code` sub-dispatch, a legacy generic result) surfaces its flattened result text through ToolRow's Output section so nothing is lost behind a bare summary ([decision](../../../.agents/notes/implemented/feature/2026-07-30-web-search-card.md)).

 声明 `search` 渲染意图的 `grep`／`glob` 调用，会在同样的渲染点上通过 ui-primitives 的 `SearchBlock` 内联渲染其结果——grep 的匹配按文件分组（每个是一个可折叠的头，下辖 `lineNumber: line` 行），glob 是扁平路径列表。`contract/search-card-model.ts` 是从快照的 `resultView` 推导的唯一位置；与终端卡片不同，它不读 `callView`，因为搜索在 `execute` 前没有匹配或路径，所以运行中的搜索只显示摘要。对任何非搜索的结果视图、当前客户端版本无法编译的 `card` 或 `kind`、以及（因为这些都与不可信的 wire 帧同行）一个 `files`／`paths` 格式错误的已知 kind，它都返回 null，落回通用路径。键控的 `SearchRow` 因推导出的 `kind` 决定形态而同时注册在 `grep` 与 `glob` 下，组合共享的 `ToolRow`，把卡片作为 ToolRow 的 `search` body 传入，因此它是该行默认折叠的展开卡片；渲染点兜底行以同样方式渲染它。两者上限都是 `CHAT_SEARCH_MAX_LINES`（8），面板为 16。被截断的搜索会从卡片里丢掉一些行，但通往其余部分的定位符——grep/glob 的 `Full … stored at …` 脚注——只存在于结果文本里，因此推导在（且仅在）结果被截断时把它作为恢复脚注画在卡片下方；一个完全没有卡片的已结算调用（出错的搜索、嵌套 `run_code` 子派发、旧日志的 generic 结果）则经 ToolRow 的 Output 区呈现其压平后的结果文本，从而不让任何内容丢失在一个光秃秃的摘要之后（[决策](../../../.agents/notes/implemented/feature/2026-07-30-web-search-card.md)）。

A pull model needs no background process, no hook installation in the user's tmux, and no teardown; it re-reads current state each turn so a moved, renamed, or re-laid-out pane is picked up naturally. Gating on the first step makes the reading per-turn: a location is stable within a turn, and re-querying every step would add cost without new information.

-An agent booted inside tmux now receives its own session/window/pane location and window layout as durable, source-attributed context, updated per turn when the location changes. Deployments opt in through cordis.yml; the default spine and shipped examples stay silent. Outside a real tmux pane — including a terminal that merely inherited `$TMUX`/`$TMUX_PANE` — or without a `ctx.bash` executor, the plugin is inert with no error, so composing it is safe everywhere. Because the reading is one durable `user/message`, it survives compaction as ordinary history, contributes nothing to system-prompt assembly or request headers, and costs at most one two-line message per changed turn. The pull model adds one `tmux display-message` subprocess (through the sandboxed bash seam) on the first step of each turn that is due. The optional interval floor is checked before the query and so suppresses both; an unchanged location is detected only by comparing the returned state, so it suppresses the injection while still paying for the query.

 DeepSeek search uses the same `DEEPSEEK_API_KEY` credential reference as the official conversation adapter. The provider resolves that reference inside every search through the optional `ctx.credentials` service; only a composition without the seam falls back to the launching process environment, and a non-empty literal `apiKey` remains the programmatic last resort. A stored or rotated Web Models key therefore reaches the next search without restarting or retaining the value on the provider. Because `WebSearchProvider.available()` is synchronous, it treats an installed resolver as locally usable and missing dynamic credentials fail the operation with the provider-specific `WEB_PROVIDER_CREDENTIAL_MISSING` code while the stable tool schema stays registered.

 **Enable search and fetch together.** Rejected because default `web_fetch` would allow model-selected anonymous outbound HTTP(S) retrieval to arbitrary URLs. Search covers discovery; deployments that accept broader retrieval can opt into `dsh-web-fetch-local` and set `dsh-tool-web`'s `fetch` option to `true` in their overlay.
 
 ## Consequences
 
-Web/headless model requests carry only the `web_search` schema and search-only prompt guidance in native mode; Code Mode exposes the same search capability beneath `run_code`. The prompt tells the model to use returned snippets and never advertises the disabled `web_fetch` tool. Search adds a complete auxiliary model call and may use the native server tool multiple times; its exact secret-free request remains reconstructable from the initiating session log. The default offers search-result snippets and source metadata but no arbitrary page retrieval; deployments that need full-page fetch must opt in. The Web snapshot lane boots the shipped tree, drives a replayed `web_search` call through the real DeepSeek provider against a local Messages fixture, asserts the durable auxiliary request and structured result, and pins the settled browser presentation. The real-composition smoke test pins the absence of `web_fetch`; provider tests pin missing, stored, and rotated credential behavior plus literal and ambient compatibility.

 DeepSeek 搜索使用与官方会话适配器相同的 `DEEPSEEK_API_KEY` 凭据引用。提供方在每次搜索内部通过可选的 `ctx.credentials` 服务解析该引用；只有未挂载该 seam 的组合才会回退到启动进程的环境变量，非空的 `apiKey` 字面值仍作为程序化配置的最后兜底。因此，由 Web 的 Models 页存储或轮换的密钥无需重启即可用于下一次搜索，提供方也无需保留该值。由于 `WebSearchProvider.available()` 是同步方法，它会将已安装解析器视为本地可用；若动态凭据缺失，操作会以提供方专属错误码 `WEB_PROVIDER_CREDENTIAL_MISSING` 失败，而稳定的工具 schema 仍保持注册。

 Every surface also registers `web_search` and only `web_search`. Search uses DeepSeek's Anthropic-compatible Messages endpoint, resolves the same `DEEPSEEK_API_KEY` reference for every call, and accepts the separate `DEEPSEEK_SEARCH_BASE_URL` endpoint override; each search is an auxiliary model request with its own latency and token cost. `web_fetch` remains disabled and the composition mounts no default fetch provider, so deployments that need arbitrary page retrieval must opt in through an overlay. The deployment decision and its security boundary live in the [default Web search Agent Note](../../.agents/notes/implemented/feature/2026-07-31-web-default-search.md).
 
-Every surface presents tools in `both` mode: the model receives every native schema **and** the Code Mode `run_code` transport, so a task that would be a long tool-call chain can be one program instead. Code Mode's trust posture is bash-equivalent by design — model code reaches Node APIs, but its tool calls pass the same `tools/pre-execute` gate as bash, and the worker adds containment bash has no equivalent for (a separate isolate, an empty environment, a heap cap, and hard termination). `DSH_TOOLS_MODE` overrides the presentation for a whole Web/headless process — `native` drops `run_code`, `code` sends only it — and any other value fails loud at boot through the `dsh-tools` config schema. It is a TEMPORARY seam, process-wide because Loader composition is static, removed once the web UI owns per-session tool-mode selection; the TUI surface ignores it (its config tree pins its own mode).
+`DSH_TOOLS_MODE` selects the tool presentation mode for the whole Web/headless process: `native` (the schema default when unset), `code` (the `run_code`-only Code Mode wire), or `both`; any other value fails loud at boot through the `dsh-tools` config schema. It is a TEMPORARY seam — process-wide because Loader composition is static — and is removed once the web UI owns per-session tool-mode selection; the TUI surface ignores it and pins `native`.
 
 Every `dsh` surface — TUI, Web, and headless — reports session telemetry by default (the row lives in the shared `base.cordis.yml`): every session-log event streams as OTLP/HTTP log records to `https://harness-telemetry.deepseeksvc.com/v1/logs` on a 10-second batch cadence. `DSH_TELEMETRY_OTLP_URL` points the exporter at a different collector; setting `DSH_TELEMETRY_DISABLED` to ANY non-empty value — including `0` or `false` — disables the row before it loads (a privacy switch prefers off-by-mistake over on-by-mistake). No redaction rule is mounted in this composition yet: exported records are the raw captured copy, including message text, tool arguments and results, and the session's working-directory path.

Subject: [PATCH 254/557] test(ui-conversation): pin all three list-summary
 shapes for the settling exemption

The mount fixture always listed the session, so the case named "no list
summary" actually exercised a row proving non-blank. An omitSummaryRow
option drops the row, and the three cases now pin blank:false, an absent
row, and the summary-proven blank open.

-`ConversationRoot` reads the session list summary's `blank` flag alongside the conversation snapshot and exempts summary-proven blank sessions from settling: `settling` additionally requires `summaryBlank !== true`, and `hero` accepts a blank composer while `openState === 'loading'` when the summary proves the session blank.

A session the list already reports as blank can only land on the hero, so hiding buys nothing and costs the visible flash; the same proof holds before the open starts (`cold`) and after one fails (`error`), where the previous conditions fell through to the active phase and rendered a docked bare composer under chrome `ConversationSession` hides for blank sessions.

+The assembled coverage is `apps/web/tests/startup-auto-selection.e2e.ts` (keyless web browser lane): it registers a workspace, holds the `session.history` response open at the browser's network boundary, and asserts the visible frame while the auto-selected open is in flight — hero phase, hero title, painted composer — plus a recorded phase timeline of exactly `['hero']` for the whole load. Holding the round-trip is what makes it a regression test rather than a race: against a loopback host the open settles too fast to sample, and with the exemption reverted the held window is precisely when the root reports `settling`.

+# Agent Note: Same-basename Workspace adoption
+
+Status: implemented
+
+English | [中文](2026-07-31-same-basename-workspace-adoption.zh.md)
+
+## Problem
+
+A Workspace is identified by its stable id and canonical directory path, while its title is mutable display metadata. The registry nevertheless rejected a new canonical path when its basename-derived title matched another Workspace. Common directory layouts such as `/a/xx` and `/b/xx` therefore could not coexist in the Web UI, even though the [domain design](../../proposed/architecture/2026-07-24-domain-kv-storage-and-workspace.md) already permits duplicate titles and every client operation addresses a Workspace by id.
+
+## Decision
+
+`ctx.workspace.create(path, title?)` treats canonical path as the only uniqueness key. Repeating the same path remains idempotent and preserves the registered title. Different canonical paths create different Workspace records and may share a title; when no title is supplied, each record still derives its title from `basename(path)` without suffixing or rewriting it.
+
+The Host's `workspace.create({ path })` adoption route inherits that rule. The Workspace manager, picker, grouping tree, selection, rename, deletion, and Session creation continue to use `WorkspaceId`, so equal labels neither merge records nor redirect an operation. The sidebar hover card exposes each canonical path when the labels need disambiguation.
+
+Explicit naming remains stricter. `workspace.create({ name })` and `workspace.rename` continue to reject a title already registered, as described by [manual Workspace naming](../feature/2026-07-25-session-list-browsing-and-manual-order.md). This prevents a user from deliberately introducing another ambiguous label while accepting collisions imposed by existing directory names. The path-adoption rule supersedes only the title-conflict clauses in the [Workspace product flow](../feature/2026-07-25-workspace-ui-product-flow.md) and [native directory picker](../feature/2026-07-27-native-workspace-directory-picker.md).
+
+The durable schema does not change: Workspace records already store id, path, and title independently, bootstrap can derive equal basenames, and startup validates duplicate paths rather than titles.
+
+## Verification
+
+Workspace registry and Host API tests create two real directories under different parents with the same final segment and assert distinct ids, paths, and durable order. The picker component renders equal labels as separate id-keyed entries. The keyless Web browser scenario adopts both directories through the composed directory flow and observes two registered and rendered Workspaces.
+
+## Alternatives considered
+
+**Keep title uniqueness and reject the second directory.** A display label would remain an accidental identity key and ordinary multi-root layouts would stay impossible to register.
+
+**Suffix colliding titles automatically.** A generated label such as `xx (2)` would no longer be the directory-derived title, would need stable allocation rules across deletion and reload, and would add state solely to conceal an identity mistake.
+
+**Use the full path as every Workspace title.** This removes the collision but makes the primary navigation label unnecessarily long. The full path remains available in the hover detail while the concise basename stays useful.
+
+**Permit collisions from explicit rename and create-by-name operations too.** The registry supports that state, but those operations intentionally ask the user to choose a display name. Retaining their conflict response preserves the existing naming guard without blocking filesystem-selected paths.
+
+## Consequences
+
+Two Workspace rows may carry the same visible title. They remain independently selectable and actionable because ids own identity; users can inspect the path or rename either row to disambiguate it. An explicit rename cannot select another row's current title, including a title that arose from same-basename adoption. No storage migration or compatibility path is required.

+# Agent Note: 接纳 basename 相同的 Workspace
+
+Status: implemented
+
+[English](2026-07-31-same-basename-workspace-adoption.md) | 中文
+
+## 问题
+
+Workspace 的身份由其稳定 id 和规范目录路径确定，标题则是可变的显示元数据。然而，只要新规范路径按 basename 派生出的标题与另一个 Workspace 相同，注册表就会拒绝该路径。因此，`/a/xx` 和 `/b/xx` 等常见目录布局无法同时出现在 Web UI 中，尽管[领域设计](../../proposed/architecture/2026-07-24-domain-kv-storage-and-workspace.md)早已允许标题重复，而且每项客户端操作都通过 id 定位 Workspace。
+
+## 决策
+
+`ctx.workspace.create(path, title?)` 仅以规范路径作为唯一性键。重复传入同一路径仍保持幂等，并保留已注册的标题。不同的规范路径会创建不同的 Workspace 记录，且可以共用标题；未提供标题时，每条记录仍从 `basename(path)` 派生标题，不添加后缀，也不改写标题。
+
+Host 的 `workspace.create({ path })` 接纳入口沿用该规则。Workspace 管理器、选择器、分组树、选择、重命名、删除和 Session 创建仍使用 `WorkspaceId`，因此相同标签既不会合并记录，也不会把操作指向其他记录。需要区分相同标签时，侧边栏悬停详情卡会显示各自的规范路径。
+
+显式命名仍采用更严格的规则。`workspace.create({ name })` 和 `workspace.rename` 仍会拒绝已注册的标题，具体见[手动 Workspace 命名](../feature/2026-07-25-session-list-browsing-and-manual-order.md)。这既防止用户主动引入另一个难以区分的标签，又允许既有目录名称造成的重名。路径接纳规则仅取代 [Workspace 产品流](../feature/2026-07-25-workspace-ui-product-flow.md)和[原生目录选择器](../feature/2026-07-27-native-workspace-directory-picker.md)中的标题冲突条款。
+
+持久化 schema 未变：Workspace 记录本就分别存储 id、path 和 title，引导初始化可以派生出相同的 basename，启动校验检查的是重复路径而非重复标题。
+
+## 验证
+
+Workspace 注册表与 Host API 测试会在不同父目录下创建两个末级名称相同的真实目录，并断言其 id 和路径互不相同，且持久顺序正确。选择器组件将相同标签渲染为按 id 区分的独立条目。无密钥 Web 浏览器场景通过组合而成的目录流程接纳这两个目录，并观察到两个 Workspace 均已注册且完成渲染。
+
+## 考虑过的替代方案
+
+**保持标题唯一，并拒绝第二个目录。** 显示标签仍会意外充当身份键，普通的多根目录布局仍无法注册。
+
+**自动为冲突标题添加后缀。** 像 `xx (2)` 这样的生成标签将不再是从目录派生的标题；系统还需要制定跨删除与重载保持稳定的分配规则，并且只为掩盖身份判定错误而增加状态。
+
+**将完整路径用作每个 Workspace 的标题。** 这会消除冲突，却使主导航标签不必要地过长。完整路径仍可在悬停详情中查看，而简洁的 basename 仍有价值。
+
+**也允许显式重命名和按名称创建操作产生重名。** 注册表支持这种状态，但这些操作本就是明确要求用户选择显示名称。保留冲突响应可维持现有命名防护，同时不阻止从文件系统选取的路径。
+
+## 后果
+
+两个 Workspace 行可能显示相同的可见标题。id 负责身份，因此两行仍可独立选择和操作；用户可以查看路径或重命名任一行以作区分。显式重命名不能采用另一个行当前使用的标题，即使该标题源自 basename 相同的目录接纳。无需存储迁移或兼容路径。

 `smoke-real.e2e.ts` is the one scenario booting the unpatched shipped tree, where the `-auto` row resolves per host; it now pins `-browse` through a `--config` overlay so the developer's display environment cannot decide whether the picker is drivable at all.

@@ -6,7 +6,7 @@ Shared Workspace browser and picker plugin. `WorkspaceBrowser` fills the sidebar
 
 The browser renders grouped or flat Session rows from the global runtime hooks and owns the Workspace add/rename and in-Workspace reorder flows. A non-blank search query replaces either browsing mode with one flat result list: case-insensitive title and Workspace substring matches appear immediately, while a 250 ms debounced Host request adds ranked current-conversation content matches and snippets. The English search input and its defensive request path remove NUL, cap the query at the wire schema's 500 UTF-16 code units without splitting a surrogate pair, and preserve the existing debounce and cancellation behavior. Each new query aborts the preceding request; a failed content search leaves metadata matches visible with a warning. The list is capped at 20, asks the user to narrow broader queries, and opens the selected Session without clearing the query or jumping to a specific event.
 
-The picker lists real Host Workspace entities through the global `useWorkspaces` hook. Selecting a Workspace invokes the slot owner's `onPick` callback to retarget the frontend Session object. Each registration declares a **directory-flow child hole** (`single` kind: `conversation.hero.workspace.directoryFlow` / `sidebar.workspaces.directoryFlow`) that the composed picker package's client half fills with its picking interaction — the [`-native`](../../host/directory-picker-native/README.md) backend's renderless OS-chooser driver today, an in-app browsing dialog under a `-browse` composition. The flat **Add workspace...** action renders only while the surface's hole is occupied (occupancy read per menu render; an empty hole means the composition has no picking affordance — the seam's documented no-flow default, under which the sidebar header drops its add button rather than offering a dead one). This package owns the trigger and the adoption: the occupant reports one picked path per open through the hole's owner conversation (`open`/`busy`/`onPicked`/`onCancel`/`onError`), and the owner adopts it through the object layer, selecting the committed Workspace only after its list projection has refreshed; cancellation is silent, and errors land in the retryable folder dialog whose **Choose again** reopens the flow. Adding has exactly one route: the occupant's own create-folder affordance already covers a brand-new directory, so no separate create-by-name dialog exists. A menu only appears where there is something to choose between — with no Workspace listed, the anchor gesture raises the flow directly instead of a one-row popover, and it waits for the list baseline before treating an empty list as final. The runtime Session and Workspace services own materialization. The Workspace row's Delete action opens a confirmation that states the retention boundary, blocks duplicate submission, and keeps failures open; success removes the group while its Sessions remain under Ungrouped. The Session row's Rename action opens the same browser-owned dialog pattern prefilled with the row's display title: no client-side conflict rule exists (the host normalizes and may reject with `title-invalid`, rendered in the dialog alert), and confirming an unchanged title is deliberately allowed — it pins the current automatic title against regeneration. The Session row's Archive action commits without a confirmation dialog (non-destructive: the log and the workspace accounting slot remain) through `ctx.workspaces.archiveSession`; the row disappears from every grouping surface — workspace groups, Ungrouped, content search, and the flat list — when the archive-set echo lands, and failures are console diagnostics that leave the tree unchanged. A blank New Session row is a pure placeholder: it renders no row menu and no time label (nothing has happened in it yet), so rename, fork, and archive first apply once the first prompt lands.

 The Session row's Fork action forks at the source's last completed turn, increments the inherited persisted title on the client, and then opens the child; a trailing ASCII or fullwidth parenthesized number is incremented in the same style, while an unnumbered title gets ` (1)` appended. The source and child always appear as peer rows within a workspace group, with lineage retained only as session data. A fork or rename failure leaves the current selection unchanged; after a rename failure, the created child remains in the list.

The gateway mirrors queued `InboxItem` occurrences from `agent/inbox/*` and broadcasts authoritative `session/queue` snapshots on every queued change and reconnect; pending steering stays outside this Web projection. `session.updateQueue` addresses one `InboxItemId`: edit replaces pending content and remove discards it. A driver claim wins races by retiring the address before admission; a later operation returns `queue-item-not-found`.

The client never infers retirement from turn or status events.

+Workspace and Session lists are separate reconnect baselines. `workspace.create({ name })` creates a uniquely titled directory under the configured root, while `workspace.create({ path })` adopts an existing canonical directory and permits basename-derived titles to repeat. `workspace.delete` removes only the Workspace registration, `session.create` accepts an optional preallocated Session id, and `host/workspace-changed`, `host/workspace-removed`, plus `host/session-added` carry committed increments in either arrival order. `workspace.archiveSession` adds one session to the registry-global archive set and answers the full updated set; `workspace.list` carries that set as the reconnect baseline and `host/archived-sessions-changed` pushes the full snapshot after every durable change.

 `session.search` is a bounded content-search projection over the sessions visible through `session.list`. The gateway asks the optional `ctx.sessionQuery` service for globally ranked current-surface user, assistant, and steering matches, consumes that stream until it has at most 20 visible session/snippet pairs plus one lookahead, and revalidates every hit against the list-derived authorization set before returning it. Provider pages start at 20 hits; when a first-page request rejects that limit, the gateway probes 10, 5, 2, then 1 and retains the learned size for continuation and stale-generation restarts. Returned snippets contain at most 240 Unicode code points, and the response schema independently enforces that bound at each client boundary. Keeping the authorization set in Host memory avoids SQLite's variable ceiling for large valid corpora without weakening visibility or ranking.

Repeated calls for that path return the existing workspace without changing its title; different paths may share a display title.
 - `ctx.workspace.get(id)` / `list()` / `resolveByPath(path)` — cache-served lookups. `list()` is synchronous and follows durable registry order; `resolveByPath` is async because it applies the same `realpath` canon and rejects a missing path rather than creating it.
 - `ctx.workspace.delete(id)` — removes only the Workspace registration, its durable order entry, and its session account. Unknown ids return `false`; a removed record returns `true`. The directory, user files, live Sessions, and persisted session logs are never touched, so those Sessions become Ungrouped. A table-write failure restores the prior order and published entity.
 - `Workspace.attachSession(id)` — validates a live or persisted session header cwd against the workspace path and prepends a new id. Unknown sessions, absent/unresolvable/non-directory cwd values, and mismatches reject without writing. `detachSession` removes only the candidate index entry.

 - `ctx.workspace.get(id)`/`list()`/`resolveByPath(path)`：由缓存提供的查找。`list()` 为同步操作，并遵循持久注册表顺序；`resolveByPath` 为异步操作，因为它采用相同的 `realpath` 规范化方式，并会拒绝缺失路径，而不是创建路径。
 - `ctx.workspace.delete(id)`：只移除 Workspace 注册记录、对应的持久顺序条目及会话归属记录。未知 id 返回 `false`，成功移除记录则返回 `true`。目录、用户文件、活跃会话和持久化会话日志绝不受影响，因此相关会话会进入 Ungrouped。表写入失败时会恢复原顺序和此前发布的实体。
 - `Workspace.attachSession(id)`：对照 workspace 路径验证实时或已持久化的会话头 cwd，并将新 id 前置。未知会话、缺失／无法解析／非目录的 cwd 值和不匹配情况都会在不写入的前提下被拒绝。`detachSession` 只移除候选索引条目。

Subject: [PATCH 259/557] fix(tui): abort the resume scan with its overlay

Review findings from ds-review-bot: closing the loading picker now
aborts the scan through the AbortSignal both query methods accept, a
signal-ignoring backend's late settlement is dropped by a staleness
check, one catch spans listing and projection so a projection failure
closes the overlay instead of stranding the loading placeholder,
setCandidates clears a stale still-loading error, and the batch
comment no longer overstates the win as scaling with session count.

 The `/resume` selector builds all candidate rows from one `projectSessions` batch; a rejected projection degrades to that row's disabled "Unreadable session" fallback exactly as a failed `readSession` did. `summarizeResumeCandidate` takes the borrowed source and retains only the record and derived scalars. The pre-handoff preflight still reads the single chosen session through `readSession`, keeping full replay validation before the process re-execs; its redundant live-session shortcut was dropped because `readSession` is already live-preferred.

The finished scan swaps rows in through `setCandidates` without replacing the overlay; a queued activation behind a closing predecessor receives an already-scanned set at construction; a scan failure closes the overlay and reports the existing failure notice.

No Draft materialize or attach transaction exists.
 - When the blank Hero re-picks the Workspace, the shell calls `connectWorkspace`; if the target session differs, the non-empty draft moves from the current shell to the target shell before the new id is opened, and the old blank session survives but is no longer current.
 - The Notifier's two-bit contract: `dirty` (snapshot freshness, clearable by an `ensureFresh` pull) and `notifyPending` (notification debt, cleared only by a flush) are mutually independent — a pull must not swallow a push, and object-layer push subscribers (watchTransaction) depend on this guarantee.

+# Agent Note: Web UI drops steer entry and interjection chrome
+
+Status: implemented
+
+English | [中文](2026-07-31-web-ui-no-steer-entry-or-interjection-chrome.zh.md)
+
+## Problem
+
+Mid-turn steering is a host/agent-loop capability (`mode:'steer'`, durable `steering/message`). The Web product already locked the composer while a turn runs and never shipped a queue/steer menu, yet the client still threaded `'queue' | 'steer'` through the input machine, `conversation.send`, and locale keys, and rendered consumed steering as a badged 「插话」/「Interjection」 bubble. That left a half-built UI surface: an unused submit mode, a product label for a gesture users cannot perform, and e2e goldens that pinned chrome the product does not own.
+
+## Decision
+
+Keep host and runtime steering intact. Remove only the Web UI entry and chrome:
+
+- `InputMachine` / `SessionInput` / `InputActions.submit` / hub `defaultSink` are queue-only; they always call `session.prompt(..., 'queue')`.
+- `ConversationService.send(text)` drops its mode argument and always queues.
+- `MessageItem`'s `steering` arm still folds durable `steering/message` content into a plain right-aligned bubble (no badge, no user IconActions) so external/host steers stay visible on replay.
+- Delete `message.steering` locale strings and the unused badge CSS.
+- The web steering e2e still POSTs `mode:'steer'` over `/api/session.prompt` and asserts durable + model-visible obedience; it no longer expects interjection chrome. Update [web input machine note](../architecture/2026-07-25-web-input-machine-and-slash-pipeline.md) fact lines to match.
+
+## Alternatives considered
+
+**Delete host steering entirely.** Out of scope; the user asked only for Web UI display and entry. Agent-loop drain, session events, and the wire mode remain load-bearing for ACP/TUI/automation.
+
+**Hide `steering/message` from the transcript.** Would lie on replay when an external client steers; rejected in favor of a plain bubble.
+
+**Keep the mode parameter but only ever pass `'queue'`.** Leaves dead API surface and tests that invent `'steer'` paths the composer cannot reach.
+
+## Consequences
+
+- Web users cannot steer from the composer or `ctx.conversation.send`; stop/cancel and Queue remain the only mid-turn controls.
+- Host-wire and non-Web clients can still steer; the Web client shows those messages without labeling them as interjections.
+- Reintroducing a dedicated steer UI would need a new product decision; do not revive the mode union or badge without one.
+
+## Testing
+
+- `packages/client/ui-conversation` unit/jsdom coverage: input machine enter/sink, ConversationService routing, MessageItem steering arm (no 「插话」), InputBar submit.
+- `apps/web/tests/steering.e2e.ts` keyless replay plus updated `settled.expected.md` (steer text without badge).

+# Agent Note: Web UI 去掉 steer 入口与插话 chrome
+
+Status: implemented
+
+[English](2026-07-31-web-ui-no-steer-entry-or-interjection-chrome.md) | 中文
+
+## 问题
+
+中途 steering 是 host／agent-loop 能力（`mode:'steer'`、持久 `steering/message`）。Web 产品已在 turn 运行中锁定 composer，且从未交付排队／steer 菜单，但客户端仍把 `'queue' | 'steer'` 穿进 input machine、`conversation.send` 与 locale 键，并把已消费的 steering 渲染成带「插话」／「Interjection」徽章的气泡。这留下半成品 UI：用不到的提交 mode、用户做不到的手势却有产品文案，以及把产品并不拥有的 chrome 钉死在 e2e golden 上。
+
+## 决策
+
+保留 host 与 runtime 的 steering。只去掉 Web UI 入口与 chrome：
+
+- `InputMachine`／`SessionInput`／`InputActions.submit`／hub `defaultSink` 仅 queue；始终调用 `session.prompt(..., 'queue')`。
+- `ConversationService.send(text)` 去掉 mode 参数，始终排队。
+- `MessageItem` 的 `steering` 分支仍把持久 `steering/message` 内容折成右对齐普通气泡（无徽章、无用户 IconActions），以便外部／host steer 在回放时仍可见。
+- 删除 `message.steering` locale 字符串与未使用的徽章 CSS。
+- web steering e2e 仍通过 `/api/session.prompt` POST `mode:'steer'`，并断言持久化与模型可见服从；不再期望插话 chrome。同步更新 [web input machine note](../architecture/2026-07-25-web-input-machine-and-slash-pipeline.md) 中的事实行。
+
+## 曾考虑的替代方案
+
+**整段删除 host steering。** 超出范围；用户只要求清 Web UI 展示与入口。agent-loop 排空、session 事件与线缆 mode 对 ACP／TUI／自动化仍是承重能力。
+
+**在 transcript 中隐藏 `steering/message`。** 外部客户端 steer 时回放会撒谎；改为普通气泡。
+
+**保留 mode 参数但永远只传 `'queue'`。** 留下死 API 面与只会虚构 composer 到不了的 `'steer'` 路径的测试。
+
+## 后果
+
+- Web 用户无法从 composer 或 `ctx.conversation.send` steer；中途控制只剩停止／取消与 Queue。
+- Host 线缆与非 Web 客户端仍可 steer；Web 客户端展示这些消息时不再标成插话。
+- 若要重新引入专用 steer UI，需要新的产品决策；没有决策就不要复活 mode 联合类型或徽章。
+
+## 测试
+
+- `packages/client/ui-conversation` unit／jsdom 覆盖：input machine enter／sink、ConversationService 路由、MessageItem steering 分支（无「插话」）、InputBar submit。
+- `apps/web/tests/steering.e2e.ts` 无密钥回放，以及更新后的 `settled.expected.md`（有 steer 正文、无徽章）。

 The installer keeps every checkout under `~/.dsh/source`: the master clone at `~/.dsh/source/master` and each install's staging checkout as a git worktree `~/.dsh/source/staging-`. The stable symlink `~/.dsh/source/current` points at the active staging worktree, and `dsh` in `~/.local/bin` links to `current/bin/dsh`, so an upgrade repoints one symlink and the `dsh` on PATH never moves. Re-running the command adds a fresh staging worktree from an updated master and repoints `current` at it.

 The installer keeps every checkout under `~/.dsh/source`: the master clone at `~/.dsh/source/master` and each install's staging checkout as a git worktree `~/.dsh/source/staging-`. The stable symlink `~/.dsh/source/current` points at the active staging worktree, and `dsh` in `~/.local/bin` links to `current/bin/dsh`, so an upgrade repoints one symlink and the `dsh` on PATH never moves. Re-running the command adds a fresh staging worktree from an updated master and repoints `current` at it. See [`scripts/install.sh`](scripts/install.sh) for alternate install locations and other options.

 Routing them through YAML made them silently droppable. `@cordisjs/plugin-include` applies a targeted patch by replacing whole top-level keys (`target[key] = value`), so a personal `~/.dsh/config.yaml` patching the `tui-agent` entry's `config` replaces the shipped block entirely. A user overlay written to change provider and model therefore deleted every resume key it did not restate, and nothing reported it: absent `resumeCommand` legitimately means "no fallback configured".
 
-Both failures were live in one real overlay. The exit hint stopped printing, because the overlay omitted `resumeCommand`. Worse, the overlay carried `resumeSessionId: !!js process.env.RESUME_SESSION_ID` — a stale line from before [the env-var bridge was removed](../../archived/architecture/2026-07-24-dsh-commander-argument-adapter.md) — which overwrote the shipped `!!js "typeof resumeSessionId === 'string' ? …"` intake with a read of a variable nothing sets. `dsh --resume ` then started a *fresh* session and said nothing, reproduced directly: the banner showed a newly minted id, not the requested one. The [`dsh meta`](../feature/2026-07-28-dsh-meta-source-workspace.md) note had recorded this silent resume as an unexplained pre-existing defect; the overlay's shallow replacement is the cause.

 Identity belongs to `agent-loop` because that is the plugin which creates configured agents, and because a patch replaces a row's whole `config`: an overlay repointing the agent row's model route would erase a launcher-set identity key.

 **`ctx.provide` is the only channel from launcher argv into a Loader-mounted plugin.** Config `!!js` expressions evaluate as `with (entry.ctx) { eval(expr) }` (`vendor/loader/src/config/utils.ts`), so a bare identifier resolves against the entry's context and nothing else reaches it. The slot therefore cannot be removed while the app bundle is mounted from YAML; what changes is that it is now internal launcher↔app plumbing instead of a documented key a config author must wire correctly.

 ## Decision
 
-`dsh meta` boots the ordinary TUI with the harness checkout as the workspace, from any directory.
+`dsh experimental-meta` boots the ordinary TUI with the harness checkout as the workspace, from any directory.
 
 The target is `SOURCE_ROOT` in `apps/cli/src/tui.ts` — `fileURLToPath(new URL('../../..', import.meta.url))`, three hops up from `apps/cli/{src,lib}` — the same constant the `harness:source` prompt section already names, so the workspace and the path advertised to the model cannot drift. It follows the launcher's real path, so a PATH symlink through `current` resolves to whichever staging worktree is active.
 
-The mechanism is one `process.chdir(workspace)` inside `runTui`, guarded by a new optional third parameter that only `runMeta` passes. The cwd *is* the workspace seam in the shipped tree: `examples/tui-agent/cordis.yml` derives the session cwd (`!!js process.cwd()`), the `./.sessions` persistence root, and the HMR watch root (`root: ['.']`) from it, so one chdir moves all three together and meta sessions land in the checkout's gitignored `.sessions/`. It runs after both `.env` layers are loaded — the bin's invoking-directory load and the personal one — so the ambient > project > personal precedence is untouched. `DEFAULT_CONFIG` and `SOURCE_ROOT` are absolute and TUI mode passes no snapshot mode, so config resolution is chdir-independent.

-`meta` accepts only `--resume `. `--config` would boot a foreign tree against the harness workspace, which is the `--config` case rather than this one; `-p` is not interactive. Both fail loud, as does an empty `--resume=` — matching the default surface, where a swallowed empty id would silently start a fresh session.
-
-**`meta` does not redeclare `--resume`.** Commander parses an option a subcommand shares with its parent into `program.opts()` and leaves the subcommand's own options object empty, so redeclaring it silently dropped the id (found by probing the adapter, not by review). The action reads `program.opts()`, which also accepts the flag on either side of the subcommand; `--help` still lists it among the parent's options.
+`experimental-meta` always starts a fresh session and accepts no options. `--config` would boot a foreign tree against the harness workspace, which is the default surface's `--config` case rather than this command; `-p` is not interactive, and resume re-enters the persisted session's own workspace through `dsh --resume `. Any leaked default-surface option fails loud.
 
 ## Testing
 
-`apps/cli/tests/args.spec.ts` extends its two existing cases rather than adding a file: routing for `meta`, `meta --resume `, and `--resume  meta` (pinning the shared-option behavior above), and exit-1 for `meta --resume=`, `meta --config`, and `meta -p`. `runMeta` itself is composition inside the module's existing `v8 ignore` block, like `runTui`.
+`apps/cli/tests/args.spec.ts` pins routing for `experimental-meta`, rejection of every leaked default-surface option, and rejection of the former `meta` name. The dispatch itself is composition inside `bin.ts`'s existing `v8 ignore` block.
 
-There is no keyless PTY smoke for this mode. The smoke harness gives each run a temp cwd, but `dsh meta` deliberately chdirs to the real checkout, so a smoke would write `.sessions/` into the live tree mid-test. Covering it properly needs an injectable target directory — a test-only seam this note declines to add for a one-line chdir.

 The mode was verified interactively instead. Launched from `$HOME`, a `pwd` tool call reports the checkout, git resolves to its branch, the session log lands under the checkout's `.sessions/` (leaving `~/.sessions` untouched and the tree free of unignored residue), and plain `dsh` from another directory still uses the invoking one.

[Launcher-owned resume identity](../architecture/2026-07-28-launcher-owned-resume-identity.md) found the cause and fixed it: a personal overlay had replaced the whole `tui-agent` config block, overwriting the shipped `resumeSessionId` intake with a read of an unset environment variable, so a valid id was silently ignored. Session identity is now a launcher-owned context slot that no config key can displace, and `meta` routes through it.
-
 ## Alternatives considered
 
 **Thread an explicit workspace through `boot` and the config tree.** Avoids mutating process-wide state, but the shipped config reads the cwd in three places (`!!js process.cwd()`, `persistenceRoot`, HMR `root`), so each would need its own new plumbing and config key to stay consistent. `chdir` before boot expresses "this is the workspace" once, at the seam that already means it.
 
-**A `--meta` flag on the default surface.** Rejected: the default surface is option-only so that subcommands do not collide with a positional, and a flag that silently relocates the workspace reads as a modifier of the current directory rather than a different target. `meta` alongside `web` matches the existing shape.
+**An `--experimental-meta` flag on the default surface.** Rejected: the default surface is option-only so that subcommands do not collide with a positional, and a flag that silently relocates the workspace reads as a modifier of the current directory rather than a different target. `experimental-meta` alongside `web` matches the existing shape.
 
 **Resolve `~/.dsh/source/current` instead of the launcher's own path.** Rejected: it would diverge from the `harness:source` prompt path whenever a non-installed checkout's `bin/dsh` is invoked directly, telling the model one source root while working in another.
 
-**Make the printed resume hint mode-aware.** Deferred here as a known cost, then delivered by [launcher-owned resume identity](../architecture/2026-07-28-launcher-owned-resume-identity.md): the exit line became a launcher-provided context slot, so meta mode prints `dsh meta --resume ` and a copied hint works from any directory. It previously came from static config as `dsh --resume {session}` and only worked when re-run from the checkout.
-
 ## Consequences
 
-Starting a session on dsh's own source is `dsh meta` from anywhere, and the workspace is guaranteed to be the same checkout the model is told about. Meta sessions are isolated in the checkout's `.sessions/`, so `dsh meta --resume` sees only other meta sessions — intended, since a session's logged cwd belongs to its workspace.
-
-The resume hint was this mode's original cost and is now resolved. [Launcher-owned resume identity](../architecture/2026-07-28-launcher-owned-resume-identity.md) made both the printed line and the in-place `/resume` handoff reproduce the mode as `dsh meta --resume ` from one shared argv helper, so a copied hint works from any directory and the handoff no longer depends implicitly on `execve` preserving the process cwd.
+Starting a session on dsh's own source is `dsh experimental-meta` from anywhere, and the workspace is guaranteed to be the same checkout the model is told about. The command always starts fresh; an ordinary `dsh --resume ` later restores the session and enters its persisted workspace.
 
 `runTui` gains an optional third parameter, so the workspace override is visible at the one function that owns TUI composition rather than hidden in a second copy of it.

 ## Decision
 
-`dsh meta` 在任意目录下都以 harness 检出为 workspace 启动普通 TUI。
+`dsh experimental-meta` 在任意目录下都以 harness 检出为 workspace 启动普通 TUI。
 
 目标是 `apps/cli/src/tui.ts` 中的 `SOURCE_ROOT`——`fileURLToPath(new URL('../../..', import.meta.url))`，从 `apps/cli/{src,lib}` 向上三级——与 `harness:source` 提示词段所用的常量完全相同，因此 workspace 与告知模型的路径不可能发生偏离。它跟随启动器的真实路径，所以经由 `current` 的 PATH 符号链接会解析到当前生效的那个 staging 工作树。
 
-机制是 `runTui` 内的一次 `process.chdir(workspace)`，由一个新的可选第三参数把守，只有 `runMeta` 会传入。在已交付的配置树中，cwd *就是* workspace 的接缝：`examples/tui-agent/cordis.yml` 由它派生出会话 cwd（`!!js process.cwd()`）、`./.sessions` 持久化根目录以及 HMR 监视根目录（`root: ['.']`），因此一次 chdir 会让三者一并移动，meta 会话则落在检出目录中被 gitignore 的 `.sessions/` 内。它在两层 `.env` 都加载之后执行——bin 对调用目录的加载与个人层加载——因此“环境中已有的值 > 项目 > 个人”的优先级不受影响。`DEFAULT_CONFIG` 与 `SOURCE_ROOT` 都是绝对路径，且 TUI 模式不传 snapshot mode，所以配置解析与 chdir 无关。

-`meta` 只接受 `--resume `。`--config` 会以 harness workspace 启动其他配置树，那属于 `--config` 的场景而非本场景；`-p` 并非交互式。两者都会明确报错，空的 `--resume=` 亦然——与默认界面一致，在那里被吞掉的空 id 会静默开启一个新会话。
-
-**`meta` 不重新声明 `--resume`。** 对于子命令与父命令共享的选项，Commander 会将其解析进 `program.opts()`，而把子命令自身的 options 对象留空；因此重新声明会静默丢弃该 id（这是通过实测适配器发现的，而非评审发现）。action 读取 `program.opts()`，这同时也允许该标志出现在子命令的任意一侧；`--help` 仍会在父命令的选项中列出它。
+`experimental-meta` 始终启动新会话，且不接受任何选项。`--config` 会针对 harness workspace 启动其他配置树，那是默认界面的 `--config` 场景，而不是该命令的场景；`-p` 并非交互式，恢复则通过 `dsh --resume ` 重新进入已持久化会话自身的 workspace。任何泄漏的默认界面选项都会明确报错。
 
 ## Testing
 
-`apps/cli/tests/args.spec.ts` 扩展其已有的两个用例而非新增文件：`meta`、`meta --resume ` 与 `--resume  meta` 的路由（钉住上述共享选项行为），以及 `meta --resume=`、`meta --config`、`meta -p` 的退出码 1。`runMeta` 自身与 `runTui` 一样，属于该模块既有 `v8 ignore` 块内的组合代码。

-该 mode 没有 keyless PTY 冒烟测试。冒烟框架会为每次运行提供临时 cwd，但 `dsh meta` 刻意 chdir 到真实检出目录，因此冒烟测试会在测试中途把 `.sessions/` 写入实际工作树。要正确覆盖它需要一个可注入的目标目录——为了一行 chdir 而引入的测试专用 seam，本 note 不予采纳。

 取而代之的是交互式验证。从 `$HOME` 启动后，`pwd` 工具调用报告的是该检出目录，git 解析到其分支，会话日志落在该检出的 `.sessions/` 下（`~/.sessions` 未被触及，工作树也没有未被忽略的残留），并且从其他目录运行的普通 `dsh` 仍使用调用目录。
 
-`dsh meta --resume <有效 id>` 曾经开启一个*新*会话而非恢复——这是默认界面上既已存在的缺陷，并非本 mode 引入。[由启动器持有的会话身份与退出行](../architecture/2026-07-28-launcher-owned-resume-identity.md) 查明了原因并将其修复：一个个人 overlay 替换了整个 `tui-agent` 配置块，用对一个未设置的环境变量的读取覆盖了已交付的 `resumeSessionId` 入口，因此有效的 id 会被静默忽略。会话标识如今是一个启动器拥有的上下文槽位，没有任何配置键能取代它，而 `meta` 经由它进行路由。

 ## Alternatives considered
 
 **通过 `boot` 与配置树显式传递 workspace。** 这可避免修改进程级状态，但已交付的配置在三处读取 cwd（`!!js process.cwd()`、`persistenceRoot`、HMR `root`），每一处都需要各自新增管线与配置键才能保持一致。启动前 chdir 只在本就表达该含义的接缝上表达一次“这就是 workspace”。
 
-**在默认界面上加一个 `--meta` 标志。** 拒绝：默认界面是纯选项形式，以免子命令与位置参数冲突；而一个会静默改变 workspace 的标志读起来像是对当前目录的修饰，而非另一个目标。`meta` 与 `web` 并列符合既有形态。

-
 ## Consequences
 
-在 dsh 自身源码上开启会话变成了在任意位置执行 `dsh meta`，且该 workspace 必然就是告知模型的那个检出目录。meta 会话被隔离在检出目录的 `.sessions/` 内，因此 `dsh meta --resume` 只能看到其他 meta 会话——这是预期行为，因为会话记录的 cwd 属于它的 workspace。
-

+在 dsh 自身源码上开启会话变成了在任意位置执行 `dsh experimental-meta`，且该 workspace 必然就是告知模型的那个检出目录。该命令始终启动新会话；之后，普通的 `dsh --resume ` 会恢复该会话并进入其已持久化的 workspace。
 
 `runTui` 新增一个可选第三参数，因此 workspace 覆盖是在拥有 TUI 组合逻辑的那唯一一个函数上可见的，而不是隐藏在它的第二份副本中。

 The local provider accepts the exact kebab-case frontmatter keys `disable-model-invocation` and `user-invocable`. It accepts YAML booleans plus case-insensitive `true`/`false`, `yes`/`no`, `on`/`off`, and `1`/`0`, matching the practical boolean forms accepted by Claude skills. It maps `disable-model-invocation` to the inverse positive field and fills both positive fields from their defaults even when neither key is present. A camel-case external spelling or non-boolean invocation value drops the entire skill from discovery with a targeted warning; this pre-release repository does not keep an on-disk compatibility alias. Invocation data fails closed because ignoring it would default to permission and could expose the skill on a disabled surface, while wrong-typed optional `whenToUse` and `metadata` values are omitted because they do not decide invocation.

The TUI `/skill:` autocomplete and exact loader enforce the user field locally, so a user-only skill is visible and loadable there even when it is absent from model discovery, without turning the optional skill peer into a runtime import. The launcher-seeded initial skill used by guided `dsh migrate` and `dsh upgrade` sessions follows this same TUI path and must remain user-invocable. The browser `skill.list` RPC serves a user-selected reference that still asks the model to load the skill, so it exposes the intersection of model- and user-invocable skills; no direct browser skill-loading RPC is added.

 The TUI surface:
 
 - boots `base.cordis.yml` plus `tui.cordis.yml` through [`dsh-app-boot`](../../packages/ui/app-boot/README.md); `--config ` applies a patch-list overlay instead of the personal overlay, while `--config-replace ` boots that file as the complete tree;
 - resumes a persisted session with `dsh --resume ` and, when the Node host exposes `process.execve`, supplies the TUI's in-place handoff host: after selector preflight and current-session flush, the host disposes the app and replaces the process with a normalized resume invocation; runtimes without process replacement leave the session running and say so. This CLI owns session identity and the exit line rather than the config: it mints or selects the `main` session id and provides it, plus the exact command that reproduces this invocation, on the boot context ([`MAIN_SESSION_ID_KEY`](../../packages/ui/tui/README.md) and `TUI_GOODBYE_MESSAGE_KEY`). No `cordis.yml` key can drop resume, and a missing or unreadable id fails loud instead of creating a fresh session;

+- treats the **invoking directory** as the workspace — sessions, relative paths, and workspace instructions resolve from the cwd (`dsh experimental-meta` is the sole exception, below);
 - tells the agent where its own source lives: after boot it adds a prompt section naming this harness checkout, resolved from the launcher's real path so it holds under a PATH symlink and an arbitrary cwd, so the self-referential `cordis` toolset can read and modify it;
 - applies the personal overlay from `~/.dsh` (see [app-boot's Personal config](../../packages/ui/app-boot/README.md#personal-config)): `config.yaml` patches the booted tree, while `.env` there is the credential provider's own store (never hoisted into the environment, so keys stay rotatable). Environment precedence is ambient > project `.env`.
 - registers bare `/compact`: while the agent is idle, it summarizes useful older history even below automatic pressure, rejects arguments, and reports success only after the standalone replacement bracket is durable. A prompt submitted during compaction keeps its queue identity and starts after that checkpoint; injected context remains visible.
 
-`dsh meta` is that same TUI with this harness checkout as the workspace, so working on dsh itself needs no `cd`. It chdirs to the checkout root — resolved from the launcher's real path, the same root the source-path prompt section names — after the environment is settled, so precedence is unchanged while the session cwd and HMR watch root move together. Meta always starts a fresh session and accepts no default-surface options; use ordinary `dsh --resume ` to resume a persisted session.

-`dsh upgrade` is a guided fresh-session entry over the default TUI surface: it mints a fresh session in the invoking directory and seeds its first turn with the bundled `dsh-upgrade` skill, exactly as if the user typed `/skill:`. The launcher passes the skill name on the boot context ([`INITIAL_SKILL_KEY`](../../packages/ui/tui/README.md)), which the TUI auto-invokes once the chat is live. Both take no options — `--config`, `-p`, and `--resume` fail loud — and seed only on this first launch, so a later `dsh --resume ` of the session is an ordinary TUI session with no re-injection.

 `dsh --dump-config` and `dsh web --dump-config` print the composed config tree — the shipped base, the surface overlay, and the `--config` or personal overlay, exactly the layers that surface would boot — as YAML on stdout and exit without booting; `--dump-default-config` stops at the surface overlay, so diffing the two shows precisely what the user layer changes. Each run of rows is preceded by a `# ==` comment naming the file it comes from and the layers that patched it (e.g. `# == base.cordis.yml, patched by tui.cordis.yml`), so the output shows provenance while staying one loadable document. Composition runs through the include's own patch algorithm and YAML dialect (`applyEntryPatches`/`entryListSchema` from `@cordisjs/plugin-include`), so the dump cannot drift from what boots; `!!js` expressions print verbatim and unevaluated, and a patch whose target row is absent is reported on stderr with its layer, mirroring the Loader's boot-time warning. Launcher-owned boot-context values (session identity, CLI-flag patches) are per-invocation facts outside the config tree and do not appear. The dump flags reject boot-only flags (`-p`, `--resume`, `--config-replace`) rather than silently ignoring them, and `--dump-default-config` takes no `--config`.

 TUI 界面：
 
 - 通过 [`dsh-app-boot`](../../packages/ui/app-boot/README.md) 启动 `base.cordis.yml` 与 `tui.cordis.yml`；`--config ` 应用一个补丁列表覆盖并替代个人覆盖，而 `--config-replace ` 将指定文件作为完整配置树启动；
 - 使用 `dsh --resume ` 恢复已持久化会话。当 Node 宿主公开 `process.execve` 时，还会提供 TUI 的原地移交宿主：选择器预检并刷新当前会话后，宿主会释放应用，并以规范化的恢复调用替换进程；不支持进程替换的运行时会让会话继续运行并给出提示。会话身份与退出行由本 CLI 拥有，而非由配置指定：它创建或选定 `main` 会话 id，并把该 id 以及可复现本次调用的确切命令一起提供到启动上下文（[`MAIN_SESSION_ID_KEY`](../../packages/ui/tui/README.md) 与 `TUI_GOODBYE_MESSAGE_KEY`）。任何 `cordis.yml` 键都无法移除恢复能力；缺失或无法读取的 id 会明确报错，而不会创建新会话；
-- 将 **调用目录** 视为 workspace：会话、相对路径和 workspace 指令都从 cwd 解析（`dsh meta` 是唯一例外，见下文）；
+- 将 **调用目录** 视为 workspace：会话、相对路径和 workspace 指令都从 cwd 解析（`dsh experimental-meta` 是唯一例外，见下文）；
 - 告知 agent 自身源码所在位置：启动后添加一个命名此 harness checkout 的提示词段。该路径从启动器的真实路径解析，因此在 PATH 符号链接和任意 cwd 下仍然有效，使自指的 `cordis` 工具集可以读取并修改它；
 - 应用 `~/.dsh` 中的个人覆盖（参见 [app-boot 的个人配置](../../packages/ui/app-boot/README.md#personal-config)）：`config.yaml` 修补已启动的树，而那里的 `.env` 是凭据 provider 自己的存储（绝不会被提升进环境，因此密钥始终可轮换）。环境优先级为环境中已有的值 > 项目 `.env`。
 - 注册裸 `/compact`：agent 空闲时，即使未达到自动压力，也会摘要有效的较早历史；该命令拒绝参数，并只在独立替换标记对持久化后报告成功。压缩（compaction）期间提交的提示词保留其队列身份，并在该检查点之后启动；注入的上下文仍保持可见。
 
-`dsh meta` 是以本 harness checkout 为 workspace 的同一个 TUI，因此开发 dsh 自身无需 `cd`。它在环境确定之后才 chdir 到 checkout 根目录（从启动器的真实路径解析，与源码路径提示词段所指的根目录相同），因此环境优先级不变，而会话 cwd 与 HMR 监视根目录会一并移动。Meta 始终创建新会话，不接受默认界面的任何选项；恢复已持久化会话应使用普通的 `dsh --resume `。

-`dsh upgrade` 是默认 TUI 界面之上的引导式全新会话入口：它在调用目录中创建一个全新会话，并以内置 `dsh-upgrade` skill 播种其首轮，效果等同于用户手动键入 `/skill:`。启动器将 skill 名称提供到启动上下文（[`INITIAL_SKILL_KEY`](../../packages/ui/tui/README.md)），TUI 在聊天就绪后自动调用它。两者都不接受任何选项——`--config`、`-p`、`--resume` 都会明确报错——且仅在首次启动时播种，因此之后 `dsh --resume ` 恢复该会话时是普通 TUI 会话，不会重复注入。

 `dsh --dump-config` 和 `dsh web --dump-config` 把合成后的配置树——已交付的基础配置、界面覆盖层，以及 `--config` 或个人覆盖层，恰好是该界面启动时组装的那些层——以 YAML 打印到 stdout 后退出，不启动任何东西；`--dump-default-config` 止步于界面覆盖层，因此对两份输出做 diff 就能精确看出用户层改了什么。每段连续的行之前都有一条 `# ==` 注释，标明该段来自哪个文件以及被哪些层修补过（例如 `# == base.cordis.yml, patched by tui.cordis.yml`），因此输出既展示来源，又仍是一份可加载的文档。合成通过 include 自己的补丁算法和 YAML 方言（`@cordisjs/plugin-include` 的 `applyEntryPatches`/`entryListSchema`）完成，因此 dump 不可能与实际启动漂移；`!!js` 表达式原样打印、不求值，目标行不存在的补丁会连同其所在层报到 stderr，与 Loader 启动时的警告一致。由启动器持有的启动上下文值（会话身份、CLI 标志补丁）是每次调用的事实，位于配置树之外，不会出现。dump 标志会拒绝仅用于启动的标志（`-p`、`--resume`、`--config-replace`）而不是静默忽略它们，`--dump-default-config` 不接受 `--config`。

The `PendingApproval` domain face in `contract/slots.ts` owns the wire encoding — the `ApprovalResponsePayload` value with the audit correlation — over the runtime's `PendingWait` carrier; the broadcast `approval/resolved` frame settles the wait and restores the composer. The sidebar mirrors the blocked state through the manager-tracked `waitingApproval` list bit (lit for uninstantiated sessions too), which outranks the running ring until the question resolves.

The composer's bottom-row Access seat mounts `PermissionSelect`, fed by the host-computed `permissions` projection through the standard-kit `useProjection` (key absence hides the chip); the chip opens a Menu-primitive dropdown whose kebab-case preset names render as title-case labels. Safe preset picks submit `/permission ` immediately through the bar's injected `command` callback, while `danger-full-access` is presented as `Full access` and first opens an in-page Modal risk confirmation.

Subject: [PATCH 270/557] feat(install): adopt an existing checkout into the
 managed layout

Running scripts/install.sh from a checkout linked `dsh` straight at that
checkout, producing an install that `dsh-upgrade` cannot upgrade (there is
no `current` to repoint), that dangles if the checkout moves, and whose
launcher resolves to an arbitrary working branch.

In-repo mode still never clones and never touches the working tree, but it
now offers to adopt the checkout, and adoption is the default. The container
owns staging worktrees and `current`; the repository is discovered via
`git rev-parse --git-common-dir` rather than owned, so a clone anywhere on
disk converges on the same upgradable layout as a curl install and both
share one worktree/exclude/lock/link sequence.

Declining, or DSH_ADOPT=0, keeps the previous link-in-place behavior with a
warning naming what it costs, preserving the path that makes this script
testable against local source.

All path comparisons run on physical paths: macOS resolves /var through a
symlink to /private/var, and comparing a resolved path against an unresolved
one misclassified an existing managed install as a foreign clone.

Verified manually (no install.spec.ts, per request) with a harness driving
the real script under a stubbed pnpm across 33 assertions, plus both
interactive outcomes under tmux.

+# Agent Note: the installer adopts an existing checkout into the managed layout
+
+Status: implemented
+
+English | [中文](2026-07-31-installer-adopts-existing-checkout.zh.md)
+
+## Problem
+
+`scripts/install.sh` produced two incompatible install shapes. A `curl … | sh` install built the managed layout — a master clone at `~/.dsh/source/master`, a staging worktree on `dsh-staging/`, and the stable `current` symlink the PATH launcher resolves through. Running the same script from a checkout instead linked `dsh` straight at that checkout's `bin/dsh`, per the earlier [in-repo skip-clone decision](../../archived/process/2026-07-22-installer-in-repo-skip-clone.md).
+
+The direct link is a terminal state. `current` is what an upgrade repoints, so an install without it is not upgradable by [`dsh-upgrade`](../../../../skills/dsh-upgrade/SKILL.md); the PATH symlink dangles if the checkout moves; and the launcher resolves to whatever branch the contributor happened to have checked out, which the upgrade contract forbids as a launcher target. The upgrade skill already described this shape as a legacy install needing a one-time migration, so the layouts diverged at install time and were reconciled only later, if ever.
+
+## Decision
+
+In-repo mode still never clones and never modifies the working tree, but it now offers to **adopt** the checkout into the managed layout, and adoption is the default.
+
+The container owns staging worktrees and `current`; the repository is *discovered*, not owned. `git rev-parse --git-common-dir` resolves the shared git directory behind the checkout — for a linked worktree that is the real clone rather than the worktree itself — and its parent is the repository that serves as the upgrade base. A staging worktree branched from the checkout's `HEAD` is then created under `$DSH_SOURCE`, and `current` points at it. A clone anywhere on disk therefore converges on the same layout as a `curl` install, and the two paths share one worktree/exclude/lock/link sequence: they differ only in whether the repository was discovered by `git clone` or by `git rev-parse`.
+
+`$DSH_SOURCE/master.path` records the resolved repository, and only when that repository lives outside the container. A container holding its own master is self-contained and gets no file, so the file's presence is itself the signal that this container depends on an outside path: each staging worktree holds an absolute gitdir pointer into that clone, so deleting the clone breaks them.
+
+Adoption branches from `HEAD`, so committed work is what runs and uncommitted changes stay in the checkout; a dirty tree is warned about before the prompt and whenever `DSH_ADOPT=1` skips it. Declining, or `DSH_ADOPT=0`, keeps the previous link-in-place behavior with a warning naming what it costs, because that path is what makes this script testable against local source. A repository with no commits cannot be branched and falls back to link-in-place; a checkout that is not a git repository fails with the `DSH_ADOPT=0` escape hatch named.
+
+`DSH_ADOPT=1` also overrides the rule that an explicit `DSH_SOURCE` opts back into cloning. Naming a container while asking for adoption otherwise silently cloned a different tree — the opposite of the request.
+
+Every path comparison runs on physical paths through a `resolve_dir` helper, and every compared value is resolved at assignment rather than at the comparison. macOS resolves `/var` through a symlink to `/private/var`, so comparing a git-reported path against an unresolved one misclassified an existing managed install as a foreign clone and would have built a second container beside the real one. The same defect recurred twice more during review — once where a curl install's `REPO_ROOT` stayed unresolved and wrote a spurious `master.path`, and once where `x=$(resolve_dir …) || x=$fallback` left an empty path because the assignment succeeds even when the substitution fails. `resolve_dir` therefore echoes a missing path back itself, and callers that need "does not exist" test the directory explicitly. `git rev-parse --path-format=absolute` would do the same job but requires git 2.31+.
+
+Before `current` is repointed, the installer rejects a staging path that resolves to the repository itself, enforcing the upgrade contract that the launcher never resolves to the master clone.
+
+## Alternatives considered
+
+**Make `~/.dsh/source/master` a symlink to the arbitrary clone.** Rejected. Git resolves the symlink and records the *real* path: a worktree created through it stores `gitdir: …//.git/worktrees/`, and `git worktree list` reports the clone. The symlink is therefore decorative — nothing reads it — while implying the container owns the repository. It also fails silently: moving the clone leaves `master` present but dangling and every staging worktree dead with `fatal: not a git repository`. Worst, it aliases two names onto one tree, so the "current must never be the master clone" check passes by string comparison while being false. `~/.dsh/source/master` is a location, not a name, and only the location is authoritative.
+
+**Promote the checkout itself to the `current` target.** Rejected: the upgrade contract requires `current` to be a clean staging worktree on a staging branch, never a feature, review, or detached checkout. It would also make every upgrade rewrite the tree the contributor is editing.
+
+**Keep adoption opt-in.** Rejected as the default: the divergent shape was the actual defect, and leaving the fix behind a flag means the common `sh scripts/install.sh` invocation keeps producing unupgradable installs. Declining is one keystroke and `DSH_ADOPT=0` is scriptable.
+
+**Put an adopted clone's staging worktrees beside the clone** (`~/src/staging-*`) rather than in `~/.dsh/source`. Rejected: `current` and the PATH launcher are per-user singletons, so scattering worktrees across clone parents reintroduces the sibling-clone sprawl the source container exists to prevent.
+
+## Consequences
+
+One layout now serves both installs, so an adopted clone is upgradable by `dsh-upgrade` without the one-time migration that skill described. In-repo runs still never mutate the working tree, and the escape hatch that keeps this script testable against local source survives behind a prompt and `DSH_ADOPT=0`.
+
+The cost is that a container adopting an outside clone is no longer self-contained: deleting that clone breaks its staging worktrees. This is inherent to reusing an existing clone rather than a property of this design — the rejected symlink hides it rather than fixing it — and `master.path` is the mitigation, not a repair.
+
+## Testing
+
+`scripts/install.sh` has no automated test, and this change does not add one: the user directed that `install.spec.ts` be left out of scope. That is a known gap on a shipped user-facing path, and the `/var` resolution defect above is exactly the class of bug a test would have caught first. The standing [`FIXME(install-ts)`](../../../../scripts/install.sh) asking for this workflow to move into a tested TypeScript entrypoint is correspondingly more pressing.
+
+Verification was manual, through a throwaway harness driving the real script with a stubbed `pnpm`: adopting a standalone clone; adopting from a linked worktree into its existing container; `DSH_ADOPT=0` preserving link-in-place; a commitless repository falling back; a dirty tree warning while leaving uncommitted work behind; a non-git checkout failing with guidance; and a `curl`-style clone install asserting both the built layout and the absence of `master.path`, which is the regression that caught the unresolved-`REPO_ROOT` defect. Both interactive outcomes were exercised under tmux: accepting ends with the launcher running from the new staging worktree while the original checkout keeps its branch and clean status, and declining reproduces the legacy shape with no staging worktree and no `current`.

+# Agent Note: 安装器把已有检出接管进受管布局
+
+Status: implemented
+
+[English](2026-07-31-installer-adopts-existing-checkout.md) | 中文
+
+## Problem
+
+`scripts/install.sh`会产生两种互不兼容的安装形态。`curl … | sh`安装会构建受管布局——`~/.dsh/source/master`处的 master 克隆、位于`dsh-staging/<时间戳>`分支上的 staging worktree，以及 PATH 启动器据以解析的稳定`current`符号链接。而从检出中运行同一脚本时，则依据此前的[检出内跳过克隆决策](../../archived/process/2026-07-22-installer-in-repo-skip-clone.md)，把`dsh`直接链接到该检出的`bin/dsh`。
+
+这种直接链接是一种终态。升级重指的正是`current`，因此缺少它的安装无法通过[`dsh-upgrade`](../../../../skills/dsh-upgrade/SKILL.md)升级；检出一旦移动，PATH 符号链接就会失效；而且启动器会解析到贡献者恰好检出的任意分支，这正是升级契约禁止作为启动器目标的情形。升级技能早已把这种形态描述为需要一次性迁移的旧式安装，于是两种布局在安装时就已分叉，并且要到很久以后才会被调和——甚至永远不会。
+
+## Decision
+
+检出内模式仍然绝不克隆、绝不修改工作树，但现在它会询问是否把该检出**接管**进受管布局，并且接管是默认选项。
+
+容器拥有 staging worktree 和`current`；仓库是被*发现*的，而非被拥有的。`git rev-parse --git-common-dir`会解析出该检出背后的共享 git 目录——对于 linked worktree，那是真正的克隆而非 worktree 自身——其父目录即是充当升级基础的仓库。随后以该检出的`HEAD`为起点，在`$DSH_SOURCE`下创建 staging worktree，并让`current`指向它。因此，磁盘上任意位置的克隆都会收敛到与`curl`安装相同的布局，且两条路径共用同一套 worktree/exclude/lock/link 流程：二者的唯一差别，只在于仓库是由`git clone`发现的，还是由`git rev-parse`发现的。
+
+`$DSH_SOURCE/master.path`记录解析出的仓库，且仅在该仓库位于容器之外时才记录。拥有自身 master 的容器是自包含的，不会生成该文件；因此该文件的存在本身就是一个信号，表明此容器依赖于外部路径：每个 staging worktree 都持有指向该克隆的绝对 gitdir 指针，删除该克隆就会破坏它们。
+
+接管以`HEAD`为分支起点，因此运行的是已提交的内容，未提交的更改仍留在检出中；工作树不干净时，会在提示前发出警告，`DSH_ADOPT=1`跳过提示时同样警告。拒绝接管或设置`DSH_ADOPT=0`将保留原有的就地链接行为，并以警告说明其代价，因为正是这条路径使本脚本能针对本地源码进行测试。没有任何提交的仓库无法创建分支，会回退到就地链接；并非 git 仓库的检出则会失败，并在错误信息中给出`DSH_ADOPT=0`这一退路。
+
+`DSH_ADOPT=1`同时会覆盖"显式`DSH_SOURCE`即回到克隆路径"的规则。否则，在请求接管的同时指定容器，反而会静默克隆另一棵树——与请求恰好相反。
+
+所有路径比较都通过`resolve_dir`辅助函数在物理路径上进行，且每个参与比较的值都在赋值时解析，而非在比较时解析。macOS 会把`/var`经符号链接解析为`/private/var`，因此拿 git 报告的路径与未解析的路径相比较，会把已有的受管安装误判为外来克隆，并在真正的容器旁再建一个容器。同一缺陷在评审过程中又出现了两次——一次是 curl 安装的`REPO_ROOT`未经解析，导致写出多余的`master.path`；另一次是`x=$(resolve_dir …) || x=$fallback`留下了空路径，因为即使命令替换失败，赋值本身仍然成功。因此`resolve_dir`会在路径不存在时原样回显该路径，而需要判断"不存在"的调用方则显式检测该目录。`git rev-parse --path-format=absolute`能完成同样的工作，但要求 git 2.31 及以上版本。
+
+在重指`current`之前，安装器会拒绝解析结果等于仓库自身的 staging 路径，以此落实"启动器绝不解析到 master 克隆"这一升级契约。
+
+## Alternatives considered
+
+**把`~/.dsh/source/master`做成指向该任意克隆的符号链接。** 已否决。Git 会解析该符号链接并记录*真实*路径：经由它创建的 worktree 会存储`gitdir: …/<克隆>/.git/worktrees/<名称>`，而`git worktree list`报告的是该克隆。因此这个符号链接纯属装饰——没有任何代码读取它——却又暗示容器拥有该仓库。它还会静默失效：移动克隆后，`master`看似仍在却已悬空，而每个 staging worktree 都会以`fatal: not a git repository`失败。最糟的是，它把两个名称别名到同一棵树上，于是"current 绝不能是 master 克隆"这项检查会在字符串比较下通过，实则为假。`~/.dsh/source/master`是位置而非名称，且只有位置具有权威性。
+
+**把检出自身提升为`current`的目标。** 已否决：升级契约要求`current`必须是位于 staging 分支上的干净 staging worktree，绝不能是 feature、review 或 detached 检出。这还会使每次升级都改写贡献者正在编辑的那棵树。
+
+**让接管保持为可选项。** 作为默认行为已否决：分叉的形态本身才是真正的缺陷，把修复藏在开关之后，意味着常见的`sh scripts/install.sh`调用仍会产生无法升级的安装。拒绝只需一次按键，而`DSH_ADOPT=0`可用于脚本。
+
+**把被接管克隆的 staging worktree 放在该克隆旁边**（`~/src/staging-*`），而非放进`~/.dsh/source`。已否决：`current`和 PATH 启动器都是每用户唯一的，因此把 worktree 散落到各个克隆的父目录中，会重新引入 source 容器本就为之而设、意在杜绝的同级克隆蔓延问题。
+
+## Consequences
+
+现在一套布局同时服务于两种安装，因此被接管的克隆无需该技能所述的一次性迁移，即可由`dsh-upgrade`升级。检出内运行仍然绝不改动工作树，而使本脚本能针对本地源码进行测试的那条退路，也以提示和`DSH_ADOPT=0`的形式保留了下来。
+
+代价是：接管外部克隆的容器不再自包含——删除该克隆会破坏其 staging worktree。这是复用已有克隆的固有属性，而非本设计带来的性质——被否决的符号链接方案只是掩盖它，而非修复它——`master.path`是缓解措施，不是修复。
+
+## Testing
+
+`scripts/install.sh`没有自动化测试，本次变更也未添加：用户明确要求把`install.spec.ts`排除在范围之外。这是一条已交付的、面向用户的安装路径上的已知缺口，而上文那个`/var`解析缺陷，恰恰属于测试本应最先捕获的那类 bug。相应地，要求把这套流程迁移到有测试覆盖的 TypeScript 入口的既有[`FIXME(install-ts)`](../../../../scripts/install.sh)也变得更为紧迫。
+
+验证是手工完成的，通过一个一次性测试装置以打桩的`pnpm`驱动真实脚本：接管独立克隆；从 linked worktree 接管进其已有容器；`DSH_ADOPT=0`保持就地链接；无提交的仓库发生回退；工作树不干净时发出警告并把未提交内容留在原处；非 git 检出失败并给出指引；以及`curl`式克隆安装同时断言所构建的布局和`master.path`的缺失——正是这项回归测试捕获了`REPO_ROOT`未解析的缺陷。两种交互结果都在 tmux 下走通：接受时，启动器最终从新的 staging worktree 运行，而原检出保持其分支不变且状态干净；拒绝时，则复现旧式形态，既无 staging worktree 也无`current`。

 The installer keeps every checkout under `~/.dsh/source`: the master clone at `~/.dsh/source/master` and each install's staging checkout as a git worktree `~/.dsh/source/staging-`. The stable symlink `~/.dsh/source/current` points at the active staging worktree, and `dsh` in `~/.local/bin` links to `current/bin/dsh`, so an upgrade repoints one symlink and the `dsh` on PATH never moves. Re-running the command adds a fresh staging worktree from an updated master and repoints `current` at it. See [`scripts/install.sh`](scripts/install.sh) for alternate install locations and other options.
 
+Running the script from an existing clone (`sh scripts/install.sh`) never clones and never modifies that working tree. It offers to *adopt* the clone: the repository behind the checkout becomes the upgrade base, and a staging worktree branched from the checkout's current `HEAD` lands under `~/.dsh/source` with `current` pointing at it, so a clone anywhere on disk gets the same upgradable layout. Adoption carries committed work only — uncommitted changes stay in the clone. Declining (or `DSH_ADOPT=0`) links `dsh` straight at that checkout instead, which is not upgradable and breaks if the checkout moves.

Subject: [PATCH 272/557] refactor(install): always adopt, dropping the
 link-in-place path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Retaining link-in-place behind a prompt and DSH_ADOPT kept the divergent
install shape that this change exists to remove, and cost a flag, a prompt,
a dirty-tree warning, a no-commit fallback, and a second linking path.

In-repo mode now adopts unconditionally. A dirty tree adopts silently:
`worktree add` from HEAD cannot carry uncommitted work, so a prompt only
adds a decision the user cannot act on differently.

The original reason for link-in-place — keeping the script testable against
local source — survives adoption, since the staging worktree branches from
the checkout's HEAD and runs the same code. DSH_SOURCE remains the escape
hatch for installing a separate tree.

Net 47 fewer lines in the installer.

 ## Decision
 
-In-repo mode still never clones and never modifies the working tree, but it now offers to **adopt** the checkout into the managed layout, and adoption is the default.
+In-repo mode still never clones and never modifies the working tree, but it now **adopts** the checkout into the managed layout unconditionally. There is no opt-out: one layout serves every install.
 
 The container owns staging worktrees and `current`; the repository is *discovered*, not owned. `git rev-parse --git-common-dir` resolves the shared git directory behind the checkout — for a linked worktree that is the real clone rather than the worktree itself — and its parent is the repository that serves as the upgrade base. A staging worktree branched from the checkout's `HEAD` is then created under `$DSH_SOURCE`, and `current` points at it. A clone anywhere on disk therefore converges on the same layout as a `curl` install, and the two paths share one worktree/exclude/lock/link sequence: they differ only in whether the repository was discovered by `git clone` or by `git rev-parse`.
 
 `$DSH_SOURCE/master.path` records the resolved repository, and only when that repository lives outside the container. A container holding its own master is self-contained and gets no file, so the file's presence is itself the signal that this container depends on an outside path: each staging worktree holds an absolute gitdir pointer into that clone, so deleting the clone breaks them.
 
-Adoption branches from `HEAD`, so committed work is what runs and uncommitted changes stay in the checkout; a dirty tree is warned about before the prompt and whenever `DSH_ADOPT=1` skips it. Declining, or `DSH_ADOPT=0`, keeps the previous link-in-place behavior with a warning naming what it costs, because that path is what makes this script testable against local source. A repository with no commits cannot be branched and falls back to link-in-place; a checkout that is not a git repository fails with the `DSH_ADOPT=0` escape hatch named.
-
-`DSH_ADOPT=1` also overrides the rule that an explicit `DSH_SOURCE` opts back into cloning. Naming a container while asking for adoption otherwise silently cloned a different tree — the opposite of the request.
+Adoption branches from `HEAD`, so committed work is what runs and uncommitted changes stay in the checkout. This is not prompted or warned about: the installer builds the layout and gets out of the way. Setting `DSH_SOURCE` to a different directory remains the one documented way to opt back into cloning a separate tree.
 
 Every path comparison runs on physical paths through a `resolve_dir` helper, and every compared value is resolved at assignment rather than at the comparison. macOS resolves `/var` through a symlink to `/private/var`, so comparing a git-reported path against an unresolved one misclassified an existing managed install as a foreign clone and would have built a second container beside the real one. The same defect recurred twice more during review — once where a curl install's `REPO_ROOT` stayed unresolved and wrote a spurious `master.path`, and once where `x=$(resolve_dir …) || x=$fallback` left an empty path because the assignment succeeds even when the substitution fails. `resolve_dir` therefore echoes a missing path back itself, and callers that need "does not exist" test the directory explicitly. `git rev-parse --path-format=absolute` would do the same job but requires git 2.31+.

-**Keep adoption opt-in.** Rejected as the default: the divergent shape was the actual defect, and leaving the fix behind a flag means the common `sh scripts/install.sh` invocation keeps producing unupgradable installs. Declining is one keystroke and `DSH_ADOPT=0` is scriptable.
+**Keep link-in-place behind a prompt or a `DSH_ADOPT` flag.** Rejected, and an earlier revision of this change shipped exactly that before it was removed. The divergent shape was the defect itself, so retaining it as an option preserves the problem and doubles the states every later change must reason about — the prompt, the flag, the dirty-tree warning, and a second linking path all existed only to keep a shape nothing should produce. The original motivation for link-in-place, keeping the script testable against local source, survives adoption: a staging worktree branched from the checkout's `HEAD` runs the same code. `DSH_SOURCE` remains the escape hatch for installing a separate tree.

+**Warn or prompt when the tree is dirty.** Rejected: `worktree add` from `HEAD` cannot carry uncommitted work, so the behavior is determined and a prompt only adds a decision the user cannot act on differently. The contract is documented instead.
 
 **Put an adopted clone's staging worktrees beside the clone** (`~/src/staging-*`) rather than in `~/.dsh/source`. Rejected: `current` and the PATH launcher are per-user singletons, so scattering worktrees across clone parents reintroduces the sibling-clone sprawl the source container exists to prevent.
 
 ## Consequences
 
-One layout now serves both installs, so an adopted clone is upgradable by `dsh-upgrade` without the one-time migration that skill described. In-repo runs still never mutate the working tree, and the escape hatch that keeps this script testable against local source survives behind a prompt and `DSH_ADOPT=0`.
+One layout now serves every install, so an adopted clone is upgradable by `dsh-upgrade` without the one-time migration that skill described, and the installer has no branch that produces an unupgradable shape. In-repo runs still never mutate the working tree.

+The cost is that a contributor can no longer point PATH at a checkout and have `dsh` follow that working tree as they switch branches: the launcher now resolves to a staging worktree pinned to the `HEAD` adopted at install time. Re-running the installer adopts the current `HEAD` again.
 
 The cost is that a container adopting an outside clone is no longer self-contained: deleting that clone breaks its staging worktrees. This is inherent to reusing an existing clone rather than a property of this design — the rejected symlink hides it rather than fixing it — and `master.path` is the mitigation, not a repair.

 `scripts/install.sh` has no automated test, and this change does not add one: the user directed that `install.spec.ts` be left out of scope. That is a known gap on a shipped user-facing path, and the `/var` resolution defect above is exactly the class of bug a test would have caught first. The standing [`FIXME(install-ts)`](../../../../scripts/install.sh) asking for this workflow to move into a tested TypeScript entrypoint is correspondingly more pressing.

+检出内模式仍然绝不克隆、绝不修改工作树，但现在它会无条件地把该检出**接管**进受管布局。不存在退出选项：一套布局服务于所有安装。
 
 容器拥有 staging worktree 和`current`；仓库是被*发现*的，而非被拥有的。`git rev-parse --git-common-dir`会解析出该检出背后的共享 git 目录——对于 linked worktree，那是真正的克隆而非 worktree 自身——其父目录即是充当升级基础的仓库。随后以该检出的`HEAD`为起点，在`$DSH_SOURCE`下创建 staging worktree，并让`current`指向它。因此，磁盘上任意位置的克隆都会收敛到与`curl`安装相同的布局，且两条路径共用同一套 worktree/exclude/lock/link 流程：二者的唯一差别，只在于仓库是由`git clone`发现的，还是由`git rev-parse`发现的。
 
 `$DSH_SOURCE/master.path`记录解析出的仓库，且仅在该仓库位于容器之外时才记录。拥有自身 master 的容器是自包含的，不会生成该文件；因此该文件的存在本身就是一个信号，表明此容器依赖于外部路径：每个 staging worktree 都持有指向该克隆的绝对 gitdir 指针，删除该克隆就会破坏它们。
 
-接管以`HEAD`为分支起点，因此运行的是已提交的内容，未提交的更改仍留在检出中；工作树不干净时，会在提示前发出警告，`DSH_ADOPT=1`跳过提示时同样警告。拒绝接管或设置`DSH_ADOPT=0`将保留原有的就地链接行为，并以警告说明其代价，因为正是这条路径使本脚本能针对本地源码进行测试。没有任何提交的仓库无法创建分支，会回退到就地链接；并非 git 仓库的检出则会失败，并在错误信息中给出`DSH_ADOPT=0`这一退路。
-
-`DSH_ADOPT=1`同时会覆盖"显式`DSH_SOURCE`即回到克隆路径"的规则。否则，在请求接管的同时指定容器，反而会静默克隆另一棵树——与请求恰好相反。

 所有路径比较都通过`resolve_dir`辅助函数在物理路径上进行，且每个参与比较的值都在赋值时解析，而非在比较时解析。macOS 会把`/var`经符号链接解析为`/private/var`，因此拿 git 报告的路径与未解析的路径相比较，会把已有的受管安装误判为外来克隆，并在真正的容器旁再建一个容器。同一缺陷在评审过程中又出现了两次——一次是 curl 安装的`REPO_ROOT`未经解析，导致写出多余的`master.path`；另一次是`x=$(resolve_dir …) || x=$fallback`留下了空路径，因为即使命令替换失败，赋值本身仍然成功。因此`resolve_dir`会在路径不存在时原样回显该路径，而需要判断"不存在"的调用方则显式检测该目录。`git rev-parse --path-format=absolute`能完成同样的工作，但要求 git 2.31 及以上版本。

Subject: [PATCH 273/557] fix(app-boot): release the terminal before a fatal
 load exit

A dsh launch whose config failed validation returned the user to a broken
shell: typing was invisible and the next command was mangled by a stray
Device Attributes reply (1;2;4cecho ...).

The Loader mounts entries concurrently, so ui-tui can already hold the
terminal (raw mode, bracketed paste, keyboard protocol, plus an in-flight
DA query) when a sibling entry rejects on its own config. installFailLoud
wrote its diagnostic and exited immediately, so nothing disposed the tree
and ProcessTerminal.stop() never ran.

Give installFailLoud an optional release teardown, awaited between the
diagnostic and the exit and bounded by FAIL_LOUD_RELEASE_TIMEOUT_MS. The
TUI launcher passes one that disposes the root context, reaching the same
shutdown() the /exit path already uses (drainInput() + ui.stop()). The
context is captured in boot()'s prepare hook because the rejection arrives
while boot() is still in flight.

Bins that pass no release keep the previous behavior exactly.

+## Problem
+
+A `dsh` launch whose config failed validation printed its diagnostic and returned the user to a broken shell. Typing was invisible, and the next command was mangled by stray text:
+
+```
+dsh: fatal load failure: ValidationError: invalid config:
+  - $.providers expected object but got [object Object] (at providers)
+$ 1;2;4cecho hello
+zsh: command not found: 4cecho
+```
+
+The Loader mounts entries concurrently, so entry failure order is not startup order. `ui-tui` activates and calls pi-tui's `ProcessTerminal.start()`, which puts stdin in raw mode, enables bracketed paste, and writes the Kitty keyboard-protocol probe — a sequence ending in a Device Attributes query (`ESC [ c`). A sibling entry (here `llm-pi-ai`) then rejects on its own config. That rejection surfaces as an unhandled rejection, and `installFailLoud` wrote one stderr line and called `process.exit(1)` immediately.
+
+Nothing disposed the tree, so `ProcessTerminal.stop()` never ran: raw mode, bracketed paste, and the keyboard protocol stayed set on the shell that outlived the process. The terminal's answer to the Device Attributes query (`1;2;4c`) arrived after exit and was read by the shell as typed input — the literal text above.
+
+The `/exit` path was never affected, because it disposes the tree and reaches the TUI's own `shutdown()`, which calls `drainInput()` (absorbing the pending reply) and then `ui.stop()`. The defect was that a *failed boot* had no path to that same teardown.
+
+## Decision
+
+`installFailLoud` takes an optional `release` teardown, awaited between the diagnostic and the exit:
+
+- The diagnostic is written **before** the release, so the reason survives a disposer that repaints or clears the screen.
+- The handler uninstalls itself before releasing. Teardown runs plugin disposers that may themselves reject, and a re-entered handler would report a cleanup failure as a second fatal load failure, burying the real one.
+- The release is bounded by `FAIL_LOUD_RELEASE_TIMEOUT_MS` (2s) and its rejection is swallowed. A wedged or failing disposer delays the fatal exit; it never cancels it.
+- Omitting `release` keeps the previous behavior exactly, so the ACP, JSON-RPC, and demo bins are unchanged.
+
+`dsh`'s TUI launcher passes a release that disposes the root context, which runs the TUI's existing `shutdown()` and hands the terminal back.
+
+The launcher captures the root context in `boot()`'s `prepare` hook rather than from its return value. The rejection arrives while `boot()` is still in flight, so `app.current` assigned after the `await` would still be `undefined` at exactly the moment the hook needs it. `prepare` runs after the Loader installs and before any config-tree entry mounts, which covers the whole window in which an entry can reject.
+
+## Alternatives considered
+
+**Reset the terminal from the fail-loud handler** (write `ESC [ ? 2004 l`, pop the keyboard protocol, clear raw mode). This duplicates pi-tui's teardown in a package that owns no terminal, and would drift as pi-tui's startup sequence changes. It also cannot absorb the in-flight Device Attributes reply, which is what corrupts the next prompt — only draining stdin while it is still raw does that.
+
+**Register a `process.on('exit')` terminal reset in the TUI.** Exit handlers are synchronous, so they cannot await `drainInput()`; the stray reply would still land. It also puts teardown on a global hook rather than the disposal path that already exists.
+
+**Have the TUI refuse to start until the tree settles.** This serializes a deliberately concurrent Loader and delays first paint for every healthy launch to fix a failure path.
+
+**Reorder config entries so `llm-pi-ai` mounts before `ui-tui`.** Ordering is not a guarantee the Loader makes, and any future entry could fail after the TUI mounts.
+
+## Consequences
+
+A failed boot now costs one tree disposal (bounded at 2s) before exit, and the exit code stays 1. In exchange, a misconfigured `dsh` returns a usable shell instead of one needing `stty sane` or `reset`.
+
+The guarantee belongs to whichever bin owns the terminal: a surface that grabs terminal state and does not pass `release` reintroduces this defect. `installFailLoud` cannot detect that on its own, since it has no view of what a mounted plugin did to the process.
+
+## Testing
+
+`packages/ui/app-boot/tests/app-boot.spec.ts` covers the release contract: the hook is awaited before the exit commits, a rejecting hook still exits 1, a never-settling hook exits after `FAIL_LOUD_RELEASE_TIMEOUT_MS` under fake timers, and the handler is uninstalled before releasing so teardown cannot re-enter it.
+
+The end-to-end symptom is terminal state after process exit — what the *shell* sees once `dsh` is gone — which no in-process assertion observes. It was verified manually in tmux against a config with a list-shaped `providers` value: before the change the next command was mangled (`zsh: command not found: 4cecho`); after it, the diagnostic is intact, the exit code is 1, and the next command runs normally. The `/exit` path was re-checked to confirm the goodbye line and exit code 0 are unchanged.

+# Agent Note：fail-loud 在退出前释放终端
+
+Status: implemented
+
+[English](2026-07-31-fail-loud-releases-the-terminal.md) | 中文
+
+## Problem
+
+配置校验失败的 `dsh` 启动会打印诊断信息，然后把用户丢回一个损坏的 shell：输入不可见，下一条命令还会被残留文本弄乱：
+
+```
+dsh: fatal load failure: ValidationError: invalid config:
+  - $.providers expected object but got [object Object] (at providers)
+$ 1;2;4cecho hello
+zsh: command not found: 4cecho
+```
+
+Loader 并发挂载各个条目，因此条目失败的顺序并不等于启动顺序。`ui-tui` 会先激活并调用 pi-tui 的 `ProcessTerminal.start()`，它把 stdin 置为 raw 模式、启用 bracketed paste，并写出 Kitty 键盘协议探测序列——该序列以一个 Device Attributes 查询（`ESC [ c`）结尾。随后某个同级条目（这里是 `llm-pi-ai`）因自身配置而 rejection。
+
+该 rejection 以未处理 rejection 的形式浮现，而 `installFailLoud` 只写一行 stderr 就立即调用 `process.exit(1)`。没有任何环节释放这棵树，因此 `ProcessTerminal.stop()` 从未执行：raw 模式、bracketed paste 和键盘协议都残留在比进程活得更久的 shell 上。终端对 Device Attributes 查询的回应（`1;2;4c`）在进程退出之后才到达，被 shell 当作用户输入读入——也就是上面那段字面文本。
+
+`/exit` 路径从不受影响，因为它会释放整棵树，从而进入 TUI 自身的 `shutdown()`：先 `drainInput()`（吸收尚未返回的响应），再 `ui.stop()`。缺陷在于**启动失败**没有通往这同一套拆卸流程的路径。
+
+## Decision
+
+`installFailLoud` 新增可选的 `release` 拆卸回调，在诊断信息与退出之间被等待：
+
+- 诊断信息在 release **之前**写出，因此即使 disposer 重绘或清屏，失败原因也不会丢失。
+- 处理函数在 release 之前先卸载自己。拆卸会执行插件 disposer，其自身可能 rejection；若处理函数被重入，就会把清理失败报告成第二次致命加载失败，从而掩盖真正的原因。
+- release 以 `FAIL_LOUD_RELEASE_TIMEOUT_MS`（2 秒）为上限，且其 rejection 被吞掉。卡住或失败的 disposer 只会延迟致命退出，绝不会取消它。
+- 不传 `release` 时行为与此前完全一致，因此 ACP、JSON-RPC 和各 demo bin 均无变化。
+
+`dsh` 的 TUI 启动器传入的 release 会释放根上下文，从而执行 TUI 已有的 `shutdown()` 并把终端交还。
+
+启动器在 `boot()` 的 `prepare` 回调中捕获根上下文，而不是取其返回值。rejection 到达时 `boot()` 尚未结算，因此在 `await` 之后赋值的 `app.current` 恰好在回调需要它的那一刻仍是 `undefined`。`prepare` 在 Loader 安装之后、任何配置树条目挂载之前运行，覆盖了条目可能 rejection 的整个窗口。
+
+## Alternatives considered
+
+**在 fail-loud 处理函数里直接重置终端**（写 `ESC [ ? 2004 l`、弹出键盘协议、清除 raw 模式）。这会在一个并不拥有终端的包里重复 pi-tui 的拆卸逻辑，并随 pi-tui 启动序列的变化而漂移。它同样无法吸收尚未返回的 Device Attributes 响应——而这正是弄乱下一个提示符的原因，只有在 stdin 仍处于 raw 模式时排空它才能解决。
+
+**在 TUI 中注册 `process.on('exit')` 终端重置。** exit 处理函数是同步的，无法等待 `drainInput()`，残留响应依旧会落到 shell；而且这把拆卸挂到全局钩子上，而非已经存在的释放路径。
+
+**让 TUI 等整棵树结算后再启动。** 这会把刻意并发的 Loader 串行化，并为修复一条失败路径而拖慢每一次正常启动的首次绘制。
+
+**调整配置顺序，让 `llm-pi-ai` 先于 `ui-tui` 挂载。** 顺序并不是 Loader 提供的保证，而且未来任何条目都可能在 TUI 挂载之后失败。
+
+## Consequences
+
+启动失败现在会在退出前多付出一次树释放的代价（上限 2 秒），退出码仍为 1。作为交换，配置错误的 `dsh` 会交还一个可用的 shell，而不是需要 `stty sane` 或 `reset` 才能恢复的终端。
+
+这项保证属于**拥有终端的那个 bin**：任何抢占终端状态却不传 `release` 的界面都会重新引入该缺陷。`installFailLoud` 自身无法察觉这一点，因为它看不到已挂载的插件对进程做了什么。
+
+## Testing
+
+`packages/ui/app-boot/tests/app-boot.spec.ts` 覆盖 release 契约：退出提交前会等待该回调；回调 rejection 时仍退出 1；在 fake timers 下，永不结算的回调会在 `FAIL_LOUD_RELEASE_TIMEOUT_MS` 后退出；以及处理函数在 release 之前已卸载，使拆卸无法重入它。
+
+端到端症状是**进程退出之后**的终端状态——即 `dsh` 消失后 shell 所看到的东西——没有任何进程内断言能观测到它。该症状在 tmux 中针对 `providers` 为列表形状的配置手工验证：修复前下一条命令会被弄乱（`zsh: command not found: 4cecho`），修复后诊断信息完整、退出码为 1、下一条命令正常执行。同时复查了 `/exit` 路径，确认告别行与退出码 0 均未改变。

 Two Loader failure classes require separate guards because tree settlement propagates neither to its caller. A failed plugin import leaves a fiber-less entry that `assertEntriesLoaded` turns into a `boot()` rejection naming every unresolved plugin. A plugin callback or config failure leaves a failed fiber because `loader.await()` settles lifecycle tasks without propagating that error; `assertEntriesActivated` awaits the fiber explicitly and includes its original stack in the startup rejection. Before throwing, the audit marks those exact rejection reasons through one process checkpoint so `installFailLoud` coalesces Loader's duplicate notification while every unrelated unhandled rejection remains fatal.
 
+The Loader mounts entries concurrently, so a surface can already own the terminal when a sibling entry rejects: exiting straight from the handler would leave raw mode, bracketed paste, and the keyboard protocol set on the user's shell, and an in-flight terminal query's reply would land as literal text at the next prompt. A terminal-owning bin therefore passes `release` to dispose the tree — running that surface's own shutdown — before the exit commits. `dsh` captures the root context in `boot()`'s `prepare` hook rather than from its return value, because the rejection arrives while `boot()` is still in flight.
+
 Bare plugin specifiers in a config (`@deepseek-ai/dsh-*`, npm packages) resolve through the Cordis Loader's internal module loader. Repository bins install Loader's optional `node-addon-require-builtin` peer; external callers must supply it or install plugins where plain Node import resolution can find them. Relative specifiers resolve against the config directory without the native helper. The built `dsh-app-boot` artifact embeds the statically mounted Include implementation while leaving Loader external, so the include tree and host bind to one Loader peer. The `dsh` source launcher additionally maps manifest-declared workspace packages to their TypeScript source; its configuration gate requires every TUI/Web bare plugin to appear in the resolver manifest's `dependencies`. The bins' subprocess smokes exercise the internal-loader path, while this package's unit suite drives `boot()` in-process against configs with relative specifiers.
 
 This package carries no loader hooks and no dev-mode surface. The [`dsh` app](../../../apps/cli/README.md) owns its Node source-launch hook and consumes these helpers for the boot sequence; built consumers continue to use plain Node package resolution.

 Loader 树结算不会向调用方传播两类故障，因此需要分别保护。插件导入失败会留下没有 fiber 的配置项，`assertEntriesLoaded` 将其转换为 `boot()` rejection，并列出每个未解析插件。插件回调或配置失败则会留下失败的 fiber，因为 `loader.await()` 只结算生命周期任务，不传播该错误；`assertEntriesActivated` 会显式等待该 fiber，并把原始错误堆栈写入启动 rejection。抛出错误前，审计会通过一个进程级检查点标记这些 rejection 的确切原因，从而让 `installFailLoud` 将 Loader 的重复通知合并为一次，而所有无关的未处理 rejection 仍然致命。

Subject: [PATCH 274/557] fix(app-boot): keep the fail-loud exit fatal while
 the terminal is released

Review of the previous commit found two defects in the release path, both
reproduced against the implementation:

- The timeout guarding a never-settling release was unref'ed. An
  unhandledRejection listener suppresses Node's default fatal exit, so with
  nothing else referenced the process reached an empty event loop and exited
  0 on the very failure it was reporting. Keep the timer referenced and clear
  it once the race settles.

- The handler uninstalled itself before awaiting the release. A second
  concurrent rejection then became uncaught and killed the process
  mid-teardown, stranding exactly the terminal state this restores. Replace
  the uninstall with a latch: the first rejection is the reported one, and
  later rejections (teardown's own included) fall through to the pending exit.

Add the PTY regression the fake-process tests cannot express: boot the shipped
tree over a fixture whose llm-pi-ai providers value is list-shaped, expect exit
1, and assert the captured bytes carry both the diagnostic and ESC[?2004l.
Against the pre-fix source the stream ends at ESC[?2004h ESC[>7u ESC[?u ESC[c
with no reset and the case fails, so it pins the actual bug.

Split the two-shape formatting test into one install per case; a latched
handler reports once by design.

-The end-to-end symptom is terminal state after process exit — what the *shell* sees once `dsh` is gone — which no in-process assertion observes. It was verified manually in tmux against a config with a list-shaped `providers` value: before the change the next command was mangled (`zsh: command not found: 4cecho`); after it, the diagnostic is intact, the exit code is 1, and the next command runs normally. The `/exit` path was re-checked to confirm the goodbye line and exit code 0 are unchanged.
+Those fake-process tests cannot observe the two failure modes that matter most — process exit code with a real event loop, and terminal state after exit — so the regression lives in `apps/cli/tests/tui-keyless-smoke.e2e.ts`. It boots the shipped tree in a real PTY over `fixtures/tui-invalid-provider.cordis.yml` (a list-shaped `providers`, the mistake users actually make), expects exit 1, and asserts the captured bytes contain both the diagnostic and `ESC[?2004l`. Against the pre-fix source the captured stream ends at `ESC[?2004h ESC[>7u ESC[?u ESC[c` with no reset, and the case fails on that assertion.
+
+Testing policy requires a PTY case whenever terminal teardown changes, and this is it. The `/exit` path keeps its existing assertion that the same reset appears on a clean exit.

 Two Loader failure classes require separate guards because tree settlement propagates neither to its caller. A failed plugin import leaves a fiber-less entry that `assertEntriesLoaded` turns into a `boot()` rejection naming every unresolved plugin. A plugin callback or config failure leaves a failed fiber because `loader.await()` settles lifecycle tasks without propagating that error; `assertEntriesActivated` awaits the fiber explicitly and includes its original stack in the startup rejection. Before throwing, the audit marks those exact rejection reasons through one process checkpoint so `installFailLoud` coalesces Loader's duplicate notification while every unrelated unhandled rejection remains fatal.

A terminal-owning bin therefore passes `release` to dispose the tree — running that surface's own shutdown — before the exit commits. `dsh` captures the root context in `boot()`'s `prepare` hook rather than from its return value, because the rejection arrives while `boot()` is still in flight.

 Bare plugin specifiers in a config (`@deepseek-ai/dsh-*`, npm packages) resolve through the Cordis Loader's internal module loader. Repository bins install Loader's optional `node-addon-require-builtin` peer; external callers must supply it or install plugins where plain Node import resolution can find them. Relative specifiers resolve against the config directory without the native helper. The built `dsh-app-boot` artifact embeds the statically mounted Include implementation while leaving Loader external, so the include tree and host bind to one Loader peer. The `dsh` source launcher additionally maps manifest-declared workspace packages to their TypeScript source; its configuration gate requires every TUI/Web bare plugin to appear in the resolver manifest's `dependencies`. The bins' subprocess smokes exercise the internal-loader path, while this package's unit suite drives `boot()` in-process against configs with relative specifiers.

 Loader 树结算不会向调用方传播两类故障，因此需要分别保护。插件导入失败会留下没有 fiber 的配置项，`assertEntriesLoaded` 将其转换为 `boot()` rejection，并列出每个未解析插件。插件回调或配置失败则会留下失败的 fiber，因为 `loader.await()` 只结算生命周期任务，不传播该错误；`assertEntriesActivated` 会显式等待该 fiber，并把原始错误堆栈写入启动 rejection。抛出错误前，审计会通过一个进程级检查点标记这些 rejection 的确切原因，从而让 `installFailLoud` 将 Loader 的重复通知合并为一次，而所有无关的未处理 rejection 仍然致命。

Subject: [PATCH 275/557] docs(app-boot): correct the pre-fix capture claim and
 pin the exit seam contract

The PTY capture does continue past the terminal-takeover bytes with the
fatal diagnostic; only the reset never follows. State that precisely in
both notes.

Document on FailLoudProcess.exit that callers treat it as the end of the
run, matching how the release path already relies on it.

 `packages/ui/app-boot/tests/app-boot.spec.ts` covers the release contract: the hook is awaited before the exit commits, a rejecting hook still exits 1, a never-settling hook exits after `FAIL_LOUD_RELEASE_TIMEOUT_MS`, and a burst of rejections reports only the first while the release still completes.

 Testing policy requires a PTY case whenever terminal teardown changes, and this is it. The `/exit` path keeps its existing assertion that the same reset appears on a clean exit.

+# Agent Note: Workspace-write defaults for shipped surfaces
+
+Status: implemented
+
+English | [中文](2026-07-31-workspace-write-surface-default.zh.md)
+
+## Problem
+
+The shipped terminal and browser surfaces exposed the same coding tools under different unconfined compositions. Web mounted the sandbox and permission services but selected `danger-full-access`; the TUI mounted the unrestricted local bash and filesystem providers directly. A fresh coding session could therefore mutate any path its same-UID process could reach before the user deliberately chose that authority.
+
+## Decision
+
+[`base.cordis.yml`](../../../../apps/cli/config/base.cordis.yml) owns one sandbox and permission stack for every shipped TUI, Web, and browser-backed headless session: `dsh-sandbox-local`, `dsh-sandbox-policy`, `dsh-bash-sandbox`, `dsh-fs-sandbox`, `dsh-user-approval`, and `dsh-permission`. The composition fallback is the `workspace-write` preset, which bundles `workspace-write` file effects with the `ask` approval policy. `DSH_PERMISSION_MODE` remains an explicit process override; a stored `permission.defaultPreset` remains the user preference for later sessions and outranks the fallback through the Settings seam.
+
+A genuinely fresh session pins `permission/preset: workspace-write`, `sandbox/mode: workspace-write`, and `approval/policy: ask` before execution. Existing and resumed sessions retain their logged permission, and changing the General-settings default affects only sessions created afterward. The browser keeps its Access picker, answerable approval cards, and risk confirmation for Full access. The TUI gains the existing `/permission` command because the shared Permission service activates its command child there.
+
+The mode governs file effects only. Sandboxed bash and filesystem mutations admit the session workspace and platform temporary roots; reads, network access, and process visibility remain outside this policy. If no platform runner can enforce a confined bash call, execution fails closed instead of falling through to an unrestricted command.
+
+## Testing
+
+The keyless shipped-TUI pseudo-terminal smoke boots the real Loader tree, reads the persisted first request, and asserts both the `sandbox_permissions`/`justification` bash schema and the initial workspace-write event triplet. The shipped-Web composition smoke asserts the same policy, approval, and Permission defaults. The assembled browser Settings snapshot opens on Workspace Write, preserves an existing workspace-write session while changing the future default, and still proves the confirmed Full-access path.
+
+## Alternatives considered
+
+**Keep the sandbox stack in `web.cordis.yml` and duplicate it into `tui.cordis.yml`.** Rejected because the plugin identities, presets, fallback, and executor swap are identical. Two copies would make a security default depend on keeping surface overlays synchronized; the shared base is their one owner.
+
+**Leave the TUI unrestricted and change only the browser fallback.** Rejected because it preserves the unexplained surface difference and leaves a fresh terminal session with the authority this decision removes.
+
+**Add a terminal approval dialog in the same change.** Rejected as a separate interaction and lifecycle decision. The TUI has no `approval/request` answerer, so a one-shot automatic escalation currently settles unavailable and fails closed; a user who needs wider authority can deliberately select another preset through `/permission`.
+
+## Consequences
+
+Fresh sessions can modify the active workspace and temporary roots without extra prompts, while an attempted mutation elsewhere is denied before it reaches the target. Full access remains available by explicit selection, and browser selection retains its acknowledgement dialog. Stored user defaults and logged session permissions are not rewritten.
+
+The browser-backed headless entry inherits the Web composition and therefore the same default. The TUI's missing approval answerer is a deliberate limitation of this change: automatic wider retries fail closed there instead of displaying a permission question.

+# Agent Note: 已交付界面的 workspace-write 默认值
+
+Status: implemented
+
+[English](2026-07-31-workspace-write-surface-default.md) | 中文
+
+## 问题
+
+已交付的终端和浏览器界面在两套不同的无约束组合下暴露相同的编码工具。Web 挂载了沙箱与权限服务，却选择 `danger-full-access`；TUI 则直接挂载不受限的本地 bash 与文件系统提供方。因此，在用户主动选择这类权限之前，全新的编码会话就能修改其同 UID 进程可达的任意路径。
+
+## 决策
+
+[`base.cordis.yml`](../../../../apps/cli/config/base.cordis.yml) 为所有已交付的 TUI、Web 以及由浏览器支撑的无头会话统一持有一套沙箱与权限栈：`dsh-sandbox-local`、`dsh-sandbox-policy`、`dsh-bash-sandbox`、`dsh-fs-sandbox`、`dsh-user-approval` 和 `dsh-permission`。组合回退值为 `workspace-write` preset，其中包含 `workspace-write` 文件效果模式与 `ask` 审批策略。`DSH_PERMISSION_MODE` 仍是显式的进程级覆盖；已存储的 `permission.defaultPreset` 仍是面向后续会话的用户偏好，并通过 Settings seam 优先于该回退值。
+
+真正的新会话会在执行前固定 `permission/preset: workspace-write`、`sandbox/mode: workspace-write` 和 `approval/policy: ask`。现有会话和恢复的会话保留日志中记录的权限，更改「通用」设置中的默认值只影响之后创建的会话。浏览器保留 Access 选择器、可应答的审批卡片，以及选择 Full access 时的风险确认。共享 Permission 服务在 TUI 中激活其命令子件，因此 TUI 会获得现有的 `/permission` 命令。
+
+该模式只管辖文件效果。受沙箱约束的 bash 与文件系统修改只允许写入会话工作区和平台临时根目录；读取、网络访问与进程可见性仍不受该策略约束。若没有平台 runner 能强制执行受限的 bash 调用，执行会以拒绝方式关闭，不会退回不受限命令。
+
+## 测试
+
+已交付 TUI 的无密钥伪终端冒烟测试会启动真实 Loader 树，读取已持久化的首个请求，并断言 bash schema 中的 `sandbox_permissions`／`justification`，以及初始的 workspace-write 事件三元组。已交付 Web 组合的冒烟测试断言相同的策略、审批与 Permission 默认值。组装后的浏览器 Settings 快照打开时选中 Workspace Write，在更改后续会话默认值时保持现有 `workspace-write` 会话不变，并仍然验证经确认后选择 Full access 的路径。
+
+## 曾考虑的替代方案
+
+**将沙箱栈留在 `web.cordis.yml`，并在 `tui.cordis.yml` 中复制一份。** 不予采纳，因为插件标识、preset、回退值与执行器替换完全相同。两份副本会让安全默认值依赖两个界面覆盖层持续同步；共享 base 才是它们的唯一归属。
+
+**保留不受限的 TUI，只更改浏览器回退值。** 不予采纳，因为这会保留无法解释的界面差异，并让全新的终端会话继续拥有本决策要移除的权限。
+
+**在同一次变更中添加终端审批对话框。** 不予采纳，因为这是另一个交互与生命周期决策。TUI 没有 `approval/request` 应答者，因此一次性自动升权当前会落定为不可用并以拒绝方式关闭；需要更宽权限的用户可以通过 `/permission` 主动选择其他 preset。
+
+## 后果
+
+全新的会话无需额外提示即可修改当前工作区与临时根目录，尝试修改其他位置则会在触及目标前被拒绝。Full access 仍可通过显式选择获得，浏览器选择时也仍会显示确认对话框。系统不会重写已存储的用户默认值和会话日志中记录的权限。
+
+由浏览器支撑的无头入口继承 Web 组合，因此默认值相同。TUI 缺少审批应答者是本次变更的明确限制：自动请求更宽权限的重试会在那里以拒绝方式关闭，而不会显示权限询问。

 The Web and headless surfaces boot `base.cordis.yml` plus `web.cordis.yml`, then apply `$DSH_HOME/config.yaml`; an explicit `--config ` replaces that personal overlay. Both surfaces otherwise share the same composition: both treat the invoking directory as the default project and Workspace root, create named Workspaces beneath that root unless `--workspace-root ` overrides it, load applicable `AGENTS.md`/`CLAUDE.md` instructions into each agent-loop request prefix with a 65,536-byte render budget, opt into first-message model titles, use the same bounded transient model-request retry policy as the TUI, and mount a disposable in-memory SQLite content-index service. That service is ACTIVE at boot, while its `node:sqlite` module and database handle open only on the first content search. This keeps Node 22 startup output free of SQLite's experimental warning before search is used; the first actual search may still emit the runtime warning. Each service instance owns its database, so parallel invocations neither share unsupported SQLite state nor leave derived index files behind, and the first search lazily reconciles live and persisted logs. Headless differs only in listening on an OS-assigned port (parallel `dsh -p` runs never collide; the stderr-printed URL opens the live session in a browser). Both need the frontend dist and client bundles built (`pnpm run build && pnpm run build:web`).
 
+The shared composition defaults new TUI, Web, and headless sessions to the `workspace-write` permission preset (`workspace-write` file mode plus `ask` approval policy). Sandbox-enforced bash and filesystem mutations may write only under the session workspace and platform temporary roots; reads, network access, and process visibility are not confined. The browser answers one-shot approval requests and exposes the Access picker; the TUI exposes `/permission`, but has no approval-request answerer, so an automatic wider retry there fails closed until the user deliberately changes the session preset. `DSH_PERMISSION_MODE` changes the process fallback, while a stored General-settings Permission value applies to later sessions without changing an open one.
+
 The shipped TUI and Web compositions register the native DeepSeek adapter plus pi-ai OpenAI and Anthropic profiles. Credentials and endpoint overrides come from the provider-standard `DEEPSEEK_API_KEY` / `DEEPSEEK_BASE_URL`, `OPENAI_API_KEY` / `OPENAI_BASE_URL`, and `ANTHROPIC_API_KEY` / `ANTHROPIC_BASE_URL` pairs in the boot's layered environment.
 
 Every surface also registers `web_search` and only `web_search`. Search uses DeepSeek's Anthropic-compatible Messages endpoint, resolves the same `DEEPSEEK_API_KEY` reference for every call, and accepts the separate `DEEPSEEK_SEARCH_BASE_URL` endpoint override; each search is an auxiliary model request with its own latency and token cost. `web_fetch` remains disabled and the composition mounts no default fetch provider, so deployments that need arbitrary page retrieval must opt in through an overlay. The deployment decision and its security boundary live in the [default Web search Agent Note](../../.agents/notes/implemented/feature/2026-07-31-web-default-search.md).

Subject: [PATCH 277/557] fix(client): floor the fork anchor to a real event
 seq
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The fork button on a stopped assistant message was inert. Frozen
interrupted nodes carry a flow-ordering seq of turnEnd.seq - 0.9, and
session.fork takes a non-negative integer on the wire, so every such
request was rejected as invalid-params before reaching the host — where
an aborted turn's logged turn/end has always made it forkable.

SessionsService.fork floors atSeq at the wire boundary. Flooring stays
inside the anchor's own turn (every turn opens with turn/start), so the
host's first-turn/end-at-or-after cut still closes on that turn.

+# Agent Note: Fork anchor floors to an event seq
+
+Status: implemented
+
+English | [中文](2026-07-31-fork-anchor-floors-to-event-seq.zh.md)
+
+## Problem
+
+The fork button on a stopped assistant message did nothing at all — no child session, no error, no visible reaction.
+
+The frozen node behind that message is not a log event. Both the live projection and the history replay mint it with a flow-ordering seq of `turnEnd.seq - 0.9`, placing it strictly after every event of the aborted turn and before the next one, and the chat view hands that node seq to the fork entry point unchanged. `session.fork` accepts a non-negative integer on the wire, so a fractional anchor is rejected as invalid-params before the request reaches the host, and the chat entry's fork call swallows failures. Nothing distinguished the rejection from an inert button.
+
+The host's cut rule was never the obstacle. An aborted turn ends with a logged `turn/end` carrying reason `aborted`, so it is a completed prefix like any other and the anchor simply never arrived.
+
+## Decision
+
+`SessionsService.fork` floors `atSeq` before the RPC. The fractional-seq convention belongs to `dsh-client-runtime`, which mints it in both the live and replay projections, so the same package converts it back to a real event seq at the wire boundary instead of every UI caller remembering to. Integer anchors are unaffected.
+
+Flooring lands inside the anchor's own turn rather than clipping backward: every turn opens with `turn/start`, so `turnEnd.seq - 1` cannot itself be an earlier turn's `turn/end`. The host's first-`turn/end`-at-or-after rule then closes on the turn the reader clicked, matching the whole-turn semantics the message-level fork button already promised for completed turns.
+
+The apiproxy fork suite pins the host half of the contract: a floored anchor inside an aborted turn cuts through that turn and seeds the child with it.
+
+## Alternatives considered
+
+**Accept fractional `atSeq` on the wire.** Rejected because the host contract is an event seq, not a position on a continuum; the fractional form is one client's rendering convention, and admitting it would leave `atSeq` alone among the seq-carrying payloads in taking non-integers.
+
+**Hide the fork button on interrupted messages.** Rejected because forking a turn the reader deliberately stopped is one of the strongest reasons to fork at all, and the capability worked host-side the whole time.
+
+**Floor in the chat entry's `forkAt` adapter.** Rejected because `ui-conversation` consumes the fractional convention without owning it; any second fork entry point would have to rediscover the same conversion.
+
+## Consequences
+
+Forking from a stopped turn produces a child seeded through that turn's `turn/end`. The frozen partial text is reconstructed from chunk events and was never an `assistant/message`, so it stays out of the child's model transcript exactly as it stays out of the source's on resume — the child resumes from the same context the source would.
+
+Fork failures stay silent in the chat entry. This bug survived because that call site discards its rejection; surfacing fork errors in the UI is a separate change.

+# Agent Note: fork 锚点向下取整到事件 seq
+
+Status: implemented
+
+[English](2026-07-31-fork-anchor-floors-to-event-seq.md) | 中文
+
+## 问题
+
+在已停止的助手消息上点 fork 毫无反应——没有子会话，没有报错，也没有任何可见变化。
+
+这条消息背后的冻结节点并不是日志事件。实时投影和历史回放都用 `turnEnd.seq - 0.9` 这个排序坐标来生成它，让它严格落在被中断轮次的所有事件之后、下一轮之前，而 chat 视图原样把这个节点 seq 交给 fork 入口。`session.fork` 在 wire 上只接受非负整数，因此分数锚点在抵达 host 之前就被判为 invalid-params，而 chat 入口的 fork 调用又吞掉了失败。于是被拒绝和按钮失灵在表现上毫无区别。
+
+host 的切分规则从来不是障碍。被中止的轮次会记录一条 reason 为 `aborted` 的 `turn/end`，它和其他轮次一样是可切分的完整前缀——只是锚点根本没送到。
+
+## 决策
+
+`SessionsService.fork` 在发起 RPC 前对 `atSeq` 向下取整。分数 seq 这个约定属于 `dsh-client-runtime`，实时投影和回放投影都由它生成，因此也由同一个包在跨出 wire 边界时把它换回真实事件 seq，而不是要求每个 UI 调用方各自记得转换。整数锚点不受影响。
+
+向下取整落在锚点自身所在的轮次内，不会回退：每一轮都以 `turn/start` 开头，所以 `turnEnd.seq - 1` 不可能是上一轮的 `turn/end`。host 随后按「首个位于锚点或其之后的 `turn/end`」收口，命中的正是读者点击的那一轮，与消息级 fork 按钮在已完成轮次上一贯承诺的整轮语义一致。
+
+apiproxy 的 fork 用例固定了 host 这一侧的契约：落在被中止轮次内的取整锚点会切穿该轮，并把它种进子会话。
+
+## 备选方案
+
+**让 wire 接受分数 `atSeq`。** 否决：host 契约要的是事件 seq，而不是连续坐标上的某个位置；分数形式只是某一个客户端的渲染约定，一旦放行，`atSeq` 会成为所有携带 seq 的载荷中唯一容忍非整数的字段。
+
+**在已中断的消息上隐藏 fork 按钮。** 否决：从读者主动叫停的那一轮分叉，恰恰是最需要 fork 的场景之一，而 host 侧这个能力一直是好的。
+
+**在 chat 入口的 `forkAt` 适配器里取整。** 否决：`ui-conversation` 只是分数约定的消费方，并不拥有它；将来任何第二个 fork 入口都得把同样的转换重新发现一遍。
+
+## 影响
+
+从已停止的轮次 fork 会得到一个种子切到该轮 `turn/end` 的子会话。被冻结的残缺文本是从 chunk 事件重建出来的，从未成为 `assistant/message`，因此它不会进入子会话的模型上下文——正如源会话恢复时它也不会进入一样，子会话拿到的上下文与源会话一致。
+
+fork 失败在 chat 入口仍然是静默的。这个 bug 能存活至今，正是因为该调用点丢弃了自己的 rejection；把 fork 错误呈现到 UI 上是另一件事。

 A service is a plugin's only API surface toward other plugins (UI components and injection faces are not APIs; a plugin nobody calls mounts no service — ui-trajectory is the minimal-plugin exemplar: no ctx service, only view-slot registrations). The roster: `ctx.connection` (api client + stream handles), `ctx.slots` (registry wrapper emitting `slots/changed`, render entry, renderer install seam), `ctx.sessions` (list store, current-session state, scope tree), `ctx.loader`, `ctx.theme`, `ctx.i18n`, `ctx.layout` (cross-plugin view navigation), `ctx.conversation` (send/cancel/startSession). Viewing state that used to live in service stores (panel widths, selection, drafts) now lives in entry-declared stores per the [slot system standard](2026-07-22-slot-type-chain-implementation.md).
 
-There is no registration model besides slots — the former view and tool rings both dissolved into it. Conversation views are entries of the `'conversation.view'` list slot ui-conversation declares, tab metadata rides the registration options (`id`/`order`/`label`), and per-view chrome lives inside the view components themselves. A tool row is a keyed child slot each view declares for itself — today `'conversation.chat.toolview'` (keyed/session), declared by the chat entry's `children` table; the key space is runtime-open (SlotMap declares slots, never keys), which is what the tool ring's open tool-name set required. The render site dispatches per row via `entryKey: toolName` with `GenericToolCard` as the call-site `fallback`; the owner payload is the uniform `ToolRowOwnerProps` (`callId`/`toolName`/`block`/`openDetails`), and `ToolRowProps` composes it with the session standard kit for registrant components. Registrants are plain plugins with zero dedicated machinery: `ctx.slots.register({ name: 'conversation.chat.toolview', key: '', inject? }, Row)`, with `inject: ['slots', 'conversation']` as the load-order seam (the conversation service being present guarantees the slot is declared). Session-dimension differentiation happens inside the component — `useSessions` reading `parentId` — not in registry predicates; interaction drafts and other row state ride the ordinary store seat. Trajectory/waterfall get same-shaped slots (names fixed by the slot-naming discipline `..`, one shared owner type) that land with their own row render sites — RendersCheck rejects a declaration nobody renders, so the two slots cannot be declared early.

 **Scope addressing** mirrors the host's agent-scope idiom: services are root singletons whose methods take no sessionId — they read the caller's scope mark (`scopeOf(ctx)`). Inside a session scope, `ctx.conversation.send('hi', 'queue')` targets that session; cross-session calls re-target by switching ctx (`ctx.sessions.scope(id)!.conversation.send(...)`); calling a scoped method from root ctx throws. Client session scopes are minted like host agent scopes (a no-op plugin fiber + a scope-key extend), built lazily on first viewing and torn down only when the session is removed and unwatched — host-session death alone does not tear a scope (it freezes into a read-only viewport).

 The tool ring is gone as independent infrastructure: a tool row is a **keyed child slot each view declares for itself**, and the client has exactly one registration model. The justification above was hollow — a keyed slot's *key space* is already runtime-open (SlotMap declares slots, never keys; the ask-user composer's `key: 'question'` was the precedent), so the open tool-name set fits `entryKey` dispatch natively.

The owner payload is the uniform `ToolRowOwnerProps` (`callId`/`toolName`/`block`/`openDetails` — details being a session-level facility, not chat-private), and `ToolRowProps` pre-composes it with the session standard kit for registrant components. A registrant is a plain plugin: `ctx.slots.register({ name: 'conversation.chat.toolview', key: '', inject? }, Row)` with `inject: ['slots', 'conversation']` as the load-order seam — apply mounts `ConversationService` *after* the chat registration, so the service being present guarantees the slot is declared, by construction.

 A `grep`/`glob` call declaring the `search` render intent renders its result inline, at the same render sites, through ui-primitives' `SearchBlock` — grep's matches grouped by file (each a collapsible header of `lineNumber: line` rows), glob's flat path list. `contract/search-card-model.ts` is the single derivation from the snapshot's `resultView`; unlike the terminal card it reads no `callView`, since a search has no matches or paths before `execute`, so a running search shows its summary alone. It yields null — the generic path — for any non-search result view, a `card` or `kind` this client version does not compile, and (because those ride the untrusted wire frame) a known kind whose `files`/`paths` is malformed. The keyed `SearchRow`, registered under both `grep` and `glob` since the derived `kind` decides the shape, composes the shared `ToolRow`, feeding the card as ToolRow's `search` body, so it is the row's collapsed-by-default expanded card; the render-site fallback routes it the same way. Both cap at `CHAT_SEARCH_MAX_LINES` (8) against the panel's 16. A capped search drops rows from the card, but the locator to the rest — grep/glob's `Full … stored at …` footer — lives only in the result text, so the derivation surfaces that as a recovery footer below the card when (and only when) the result was truncated; a settled call with no card at all (an errored search, a nested `run_code` sub-dispatch, a legacy generic result) surfaces its flattened result text through ToolRow's Output section so nothing is lost behind a bare summary ([decision](../../../.agents/notes/implemented/feature/2026-07-30-web-search-card.md)).
 
-Tool rows are slots too — the standalone tool ring (`ToolViewRegistry`/`ctx.toolviews`/outlet) is retired. The chat entry declares the keyed `'conversation.chat.toolview'` hole (session scope; the key space is runtime-open); its render site dispatches per row via `entryKey: toolName` with `GenericToolCard` as the call-site `fallback`. The owner payload is the uniform `ToolRowOwnerProps` (`callId`/`toolName`/`block`/`openFile`) and `ToolRowProps` pre-composes it with the session standard kit. A registrant is a plain plugin: `ctx.slots.register({ name: 'conversation.chat.toolview', key: '', inject? }, Row)` with `inject: ['slots', 'conversation']` as the load-order seam (apply mounts ConversationService after the chat registration, so the service being present guarantees the slot is declared); session differentiation happens inside the component (`useSessions` reading `parentId` — the bash sample is the third-party-posture exemplar). Trajectory/waterfall toolview slots share this shape and land with their own render sites (RendersCheck rejects a declaration nobody renders).

 The todo surfaces are two registrations over that shape, both plain registrant plugins with `inject: ['slots', 'conversation']`. `TodoRow` takes the `'conversation.chat.toolview'` key `todo_write` and summarizes what the call attempted (`/ 已完成 · ` parsed from its args, falling back to the generic summary on malformed or wrongly-shaped model JSON, and keeping the generic dot for non-ok execution states so a cancelled call never reads as a completed update). `TodoDock` takes the `'conversation.input.dock'` list slot at `order: -1` — above the queue rows — and is the plan strip: it reads the host-computed `todos` projection via `useProjection` (standing plan: latest `todo/write` with no later `turn/start`) and renders `TodoPanel`, which takes the plain list, hides itself while the list is empty, and starts collapsed as a header of title plus `"/ tasks ·  in progress"` (status glyphs are the figma check / progress / dashed-pending set). The dock adapter owns the selection so the panel stays a pure function of its props; the standing list lives here rather than in the row so the row stays one line. Anything the input-zone composer chain hides (a `conversation.composer` takeover such as ui-question's) hides the whole dock, this strip included.

 声明 `search` 渲染意图的 `grep`／`glob` 调用，会在同样的渲染点上通过 ui-primitives 的 `SearchBlock` 内联渲染其结果——grep 的匹配按文件分组（每个是一个可折叠的头，下辖 `lineNumber: line` 行），glob 是扁平路径列表。`contract/search-card-model.ts` 是从快照的 `resultView` 推导的唯一位置；与终端卡片不同，它不读 `callView`，因为搜索在 `execute` 前没有匹配或路径，所以运行中的搜索只显示摘要。对任何非搜索的结果视图、当前客户端版本无法编译的 `card` 或 `kind`、以及（因为这些都与不可信的 wire 帧同行）一个 `files`／`paths` 格式错误的已知 kind，它都返回 null，落回通用路径。键控的 `SearchRow` 因推导出的 `kind` 决定形态而同时注册在 `grep` 与 `glob` 下，组合共享的 `ToolRow`，把卡片作为 ToolRow 的 `search` body 传入，因此它是该行默认折叠的展开卡片；渲染点兜底行以同样方式渲染它。两者上限都是 `CHAT_SEARCH_MAX_LINES`（8），面板为 16。被截断的搜索会从卡片里丢掉一些行，但通往其余部分的定位符——grep/glob 的 `Full … stored at …` 脚注——只存在于结果文本里，因此推导在（且仅在）结果被截断时把它作为恢复脚注画在卡片下方；一个完全没有卡片的已结算调用（出错的搜索、嵌套 `run_code` 子派发、旧日志的 generic 结果）则经 ToolRow 的 Output 区呈现其压平后的结果文本，从而不让任何内容丢失在一个光秃秃的摘要之后（[决策](../../../.agents/notes/implemented/feature/2026-07-30-web-search-card.md)）。

-Four behavioral deltas were accepted deliberately, not overlooked. Cross-view appearance is per-view registration — a row must adapt to each view's layout anyway, so one registration per view is the correct coupling, and reuse is the same component in two register calls. Same-key double registration is a loud throw where the registry let later-wins silently override — a discipline correction, not a loss. Session-dimension dispatch moved from registry predicates into the component. Registry-level shape override by third parties (a scoped registration shadowing a global one) has no equivalent; a real future need routes through key-naming conventions or a small in-component resolver, never a revived parallel registry.

+# Agent Note: Web stop preserves pending Queue
+
+Status: implemented
+
+English | [中文](2026-07-31-web-stop-preserves-queue.zh.md)
+
+## Problem
+
+The Web stop button reached `session.cancel`, which mapped to broad `agent.cancel({ kind: 'user' })`. During an active turn, ordinary composer submissions are already accepted as independently addressable Queue occurrences. Broad cancellation discarded every occurrence when the user intended to stop only the current generation, conflating turn interruption with the Queue's explicit delete operation.
+
+The browser cannot repair that loss by resending visible rows. It does not own their live `InboxItemId`, wake policy, or claim race, and a resend can duplicate work that the Host has already claimed.
+
+## Decision
+
+`session.cancel` is the Web Host API's active-turn stop. It calls `agent.cancel({ kind: 'user' }, { keepInbox: true })`, preserving pending inbox work while cooperatively aborting the current turn. The underlying option preserves queued and steering entries; the Web Queue projection continues to expose only queued entries.
+
+The AgentLoop starts no concurrent replacement turn. It closes and flushes the interrupted turn, reaches cancellation quiescence, and then claims the next waking queued occurrence through its existing FIFO driver. That claim emits `agent/inbox/dequeue`, so the Host's authoritative `session/queue` snapshot retires the claimed row and leaves the remaining tail visible. The browser neither resends nor promotes any row. Work that ignores cancellation delays this handoff until it settles.
+
+This mapping changes only the Host `session.cancel` endpoint used by Web clients. The default `Agent.cancel()` contract remains broad, ACP and TUI retain their existing cancellation policies, and `AgentHandle.dispose()` still clears pending work during teardown. Queue row removal remains the explicit Web action for discarding one pending occurrence.
+
+## Alternatives considered
+
+**Keep broad cancellation for the stop button.** Rejected because stopping one generation should not destroy independently queued user intent; the Queue already owns explicit deletion.
+
+**Resend the next row from the browser after cancellation.** Rejected because the Host owns occurrence identity and claim order. Client resubmission can duplicate work, reorder the FIFO, or race an authoritative dequeue.
+
+**Start the next turn before cancelled work reaches quiescence.** Rejected because two turns would concurrently mutate one session log and share Agent-owned resources. Cooperative cancellation waits truthfully for the active work to settle.
+
+**Add a wire option for broad versus preserving cancellation.** Rejected until the Web product has a separate “stop and clear Queue” interaction. The existing stop button has one policy, while per-row delete already supplies the current discard control.
+
+## Verification
+
+AgentLoop coverage holds an active model stream, queues two waking turns, cancels with `keepInbox`, and pins the aborted-then-completed turn reasons, FIFO user-message order, absence of discard events, and eventual idle state. The keyless Web scenario drives the built composition over HTTP/SSE: it stops one hung turn, observes the next queued occurrence start while the tail remains visible, stops that turn, and observes the final queued occurrence complete. Its accessibility snapshot pins the intermediate preserved-Queue state.
+
+## Consequences
+
+Web stop preserves accepted queued intent and advances it automatically after truthful cancellation settlement. Queue rows may remain visible while uncooperative active work winds down, and external steering preserved by the same inbox option can enter the next admitted turn even though Web does not render steering in QueueDock. A future bulk-clear interaction requires an explicit product action rather than overloading stop.

+Web 停止按钮调用 `session.cancel`，后者映射到广义 `agent.cancel({ kind: 'user' })`。在活动轮次期间，普通 composer 提交已经被接纳为可独立寻址的 Queue 入队项。用户只想停止当前生成时，广义取消却会丢弃所有入队项，混淆了轮次中断与 Queue 的显式删除操作。
+
+浏览器无法通过重发可见行修复这一损失。它不拥有这些行的实时 `InboxItemId`、唤醒策略或认领竞态；重发还可能重复 Host 已认领的工作。
+
+## 决策
+
+`session.cancel` 是 Web Host API 的活动轮次停止操作。它调用 `agent.cancel({ kind: 'user' }, { keepInbox: true })`，在协作式中止当前轮次的同时保留待处理 inbox 工作。底层选项会保留 queued 和 steering 入队项；Web Queue 投影继续只暴露 queued 入队项。
+
+AgentLoop 不会启动并发的替代轮次。它会关闭并 flush 被中断的轮次，达到取消的完全停稳，然后通过现有 FIFO 驱动器认领下一个可唤醒的 queued 入队项。该认领会发出 `agent/inbox/dequeue`，因此 Host 的权威 `session/queue` 快照会退役已认领行，并使剩余队尾保持可见。浏览器既不重发，也不提升任何行。忽略取消的工作会延迟这一交接，直到该工作结算。
+
+该映射只更改 Web 客户端使用的 Host `session.cancel` 端点。`Agent.cancel()` 默认契约仍为广义取消，ACP 和 TUI 保留既有取消策略，`AgentHandle.dispose()` 在拆卸期间仍会清除待处理工作。移除 Queue 行仍是用于丢弃单个待处理入队项的显式 Web 操作。
+
+## 考虑过的替代方案
+
+**停止按钮继续使用广义取消。** 之所以否决：停止一次生成不应销毁已独立排队的用户意图；Queue 已拥有显式删除操作。
+
+**取消后由浏览器重发下一行。** 之所以否决：Host 拥有入队项标识和认领顺序。客户端重新提交可能重复工作、重排 FIFO，或与权威出队产生竞态。
+
+**被取消工作达到完全停稳之前启动下一轮次。** 之所以否决：两个轮次会并发修改同一会话日志，并共享 Agent 拥有的资源。协作式取消会如实等待活动工作结算。
+
+**为广义取消与保留式取消添加协议选项。** 之所以否决：在 Web 产品提供独立的「停止并清空 Queue」交互之前，不需要此选项。现有停止按钮只有一项策略，而逐行删除已提供当前的丢弃控件。
+
+## 验证
+
+AgentLoop 覆盖会保持一个活动模型流，将两个可唤醒轮次排队，使用 `keepInbox` 取消，并固定验证先中止、后完成的轮次原因，FIFO 用户消息顺序，不存在 discard 事件，以及最终空闲状态。无密钥 Web 场景通过 HTTP／SSE 驱动已组装组合：它停止一个卡住的轮次，观察队尾保持可见时下一个 queued 入队项开始，再停止该轮次，并观察最后一个 queued 入队项完成。其可访问性快照固定了中间的 Queue 保留状态。
+
+## 后果
+
+Web 停止会保留已接纳的排队意图，并在取消如实结算后自动推进。不配合取消的活动工作收尾时，Queue 行可能仍保持可见；由同一 inbox 选项保留的外部 steering 可以进入下一个已接纳轮次，尽管 Web 不会在 QueueDock 中渲染 steering。未来的批量清空交互需要显式的产品操作，而不是过载停止。

 Session model routing is a session-domain contract. `session.models` returns the selected provider/model/reasoning target with provider-grouped advisory models, exact-route reasoning metadata, and provider-local lookup failures. `session.selectModel` validates the optional adapter-owned reasoning effort and replaces the complete target selected for the next prompt-assembly boundary. Catalog membership is not validation: an adapter may resolve an unlisted model, while an unavailable route or unsupported effort returns `model-unavailable`.
 
-Pending queued input is a live control-plane contract, not session history. The gateway mirrors queued `InboxItem` occurrences from `agent/inbox/*` and broadcasts authoritative `session/queue` snapshots on every queued change and reconnect; pending steering stays outside this Web projection. `session.updateQueue` addresses one `InboxItemId`: edit replaces pending content and remove discards it. A driver claim wins races by retiring the address before admission; a later operation returns `queue-item-not-found`. The operation queries only an attached Agent and never resumes a cold session because process-local inbox identities do not survive restart or disposal. The client never infers retirement from turn or status events.

The gateway mirrors queued `InboxItem` occurrences from `agent/inbox/*` and broadcasts authoritative `session/queue` snapshots on every queued change and reconnect; pending steering stays outside this Web projection. `session.updateQueue` addresses one `InboxItemId`: edit replaces pending content and remove discards it. `session.cancel` aborts only the active turn and preserves pending inbox work; after cancellation reaches quiescence and the closing turn flushes, AgentLoop claims the next waking occurrence in FIFO order. The browser never resends or promotes that occurrence. A driver claim wins races by retiring the address before admission; a later operation returns `queue-item-not-found`. Queue operations query only an attached Agent and never resume a cold session because process-local inbox identities do not survive restart or disposal. The client never infers retirement from turn or status events.
 
 Workspace and Session lists are separate reconnect baselines. `workspace.create({ name })` creates a uniquely titled directory under the configured root, while `workspace.create({ path })` adopts an existing canonical directory and permits basename-derived titles to repeat. `workspace.delete` removes only the Workspace registration, `session.create` accepts an optional preallocated Session id, and `host/workspace-changed`, `host/workspace-removed`, plus `host/session-added` carry committed increments in either arrival order. `workspace.archiveSession` adds one session to the registry-global archive set and answers the full updated set; `workspace.list` carries that set as the reconnect baseline and `host/archived-sessions-changed` pushes the full snapshot after every durable change. Archiving hides the session from grouping surfaces without touching its log or its workspace account; a session neither live nor persisted fails with `session-not-found`. Registration deletion preserves the directory and session logs; its Sessions remain in `session.list` and become Ungrouped. `SessionSummary.blank` and the `host/session-added` frame carry the derived zero-events bit: clients hide blank sessions and reuse them per workspace, flip blank on the first `host/session-status(running:true)`, and treat `session.list` as the reconnect authority; cold summaries are never blank because lazy persistence keeps never-appended sessions out of `list()`.

 `GoalBar` (`packages/client/ui-goal/src/client/GoalBar.tsx`) is a props-driven, self-contained component registered first in the composer's input-dock list. Its standalone 752px card follows the composer's horizontal geometry, and every visible state shares one fixed 36px height so switching phases never resizes it. Loading (`goal === undefined`), absent (`goal === null`), and `phase === 'complete'` render nothing — a completed goal is history, not chrome.
 
-Visibility drives the label and actions: active shows "Ongoing Goal" with pause/edit/clear; paused shows "Paused Goal" and swaps pause for a resume icon button; blocked shows "Blocked Goal" and carries `blockedReason.message` as the strip's `title` tooltip. Goal creation lives on the `/goal` command, not in the bar. The pencil swaps the strip for an inline edit form prefilled with the current objective: Enter or the check button saves through `GoalBarActions.onEdit(objective)`, Esc cancels, and an all-whitespace objective keeps save disabled. The form closes only when the edit succeeds; a failure preserves the draft and displays the error in the bar. Resume and clear failures are displayed there as well. Clear otherwise calls `onClear` directly with no confirmation — a clear keeps a durable tombstone, so nothing is unrecoverable. An effect keyed on the goal's id drops the edit form when the goal's identity changes, so a surviving draft can never be written over the goal that replaced it.

Clear otherwise calls `onClear` directly with no confirmation — a clear keeps a durable tombstone, so nothing is unrecoverable. Every mutation first acquires a synchronous component-local single-flight latch because React's pending-state render cannot close the same-frame click window. A successful clear also suppresses that exact goal id immediately while the authoritative null projection catches up, so an acknowledged tombstone cannot leave a stale clear control that submits `GOAL_NOT_FOUND`; a failure releases the latch and remains retryable. An effect keyed on the goal's id resets this transient state and drops the edit form when the goal's identity changes, so neither a cleared marker nor a surviving draft can affect the replacement goal.
 
 `GoalBarActions` lives in ui-goal's slot contract (`packages/client/ui-goal/src/client/slots.ts`) and carries exactly the rendered verbs: `onEdit`/`onPause`/`onResume`/`onClear`. Each callback asynchronously returns an explicit success/failure result so `GoalBar` owns its transitions and error display. `apply.ts` wires them to the runtime session methods; the runtime session resolves the current goal's compare-and-set ref internally, so the UI passes no ref.

 ## Testing

 ## Consequences
 
 - Goal presence in the web UI is a standalone composer-context strip: sparkle, phase label, truncated objective, and pause/edit/clear (resume replacing pause when paused) — the browser client's first goal surface.
+- Goal mutations are single-flight within the component; a successful clear hides its exact goal immediately while projection delivery converges, preventing duplicate CAS errors without making transient UI state authoritative.
 - The runtime session exposes the goal verbs over RPC with folded transport errors, and refreshes the snapshot's goal on open and on live goal-change meta (coalesced, guarded against stale reads).
 - Objective editing is reachable from the UI for the first time, through `goal.edit` with the runtime-owned ref; complete remains available to other surfaces (`/goal`, model tools).
 - `goal === null` renders nothing; the composer carries no persistent create affordance — creation is the `/goal` command's job.

 Compaction renders as one collapsed row at the checkpoint's flow position without replacing the transcript above it.

Without a current session it renders a disabled input bar; its root-scoped `conversation.hero.workspace` slot hosts the Workspace picker.

Blank sessions render the same composer body as active sessions, while the InputHub carries drafts across Workspace switches and mirrors them into the session store.

Wheel over the textarea chains: the capped draft scrolls locally until its edge, then forwards to that host.
 
 The view ring IS a slot: the conversation registration declares the `'conversation.view'` list slot (session scope) in its `children` table, ConversationRoot renders the active entry through its renderSlot share (`only: `), and view tabs project from the ring ledger's registration options (`id`/`order`/`label`). The chat view is this package's own ring entry; other plugins (ui-trajectory) contribute tabs through plain `ctx.slots.register` — the former package-local view registry (`registerView`/`ViewEntry`/`ConversationViewMap` and the chrome attachment table) is retired, with per-view chrome dissolved into the view components themselves.

Subject: [PATCH 288/557] cleanup(install): drop the master.path record

Nothing read it. The launcher, dsh-upgrade, and the installer's own re-run
all ignored the file, and the diagnostic it was meant to feed was never
built, so it was write-only state.

Git already owns the fact it recorded: a staging worktree's .git file names
the repository path, and `git worktree list` in that clone enumerates every
worktree depending on it. An installer-written copy only adds state that can
go stale while nothing validates it.

The containment caveat it documented is real and stays in the script header
and the Agent Note, now pointing at git's own records.

 The container owns staging worktrees and `current`; the repository is *discovered*, not owned. `git rev-parse --git-common-dir` resolves the shared git directory behind the checkout — for a linked worktree that is the real clone rather than the worktree itself — and its parent is the repository that serves as the upgrade base. A staging worktree branched from the checkout's `HEAD` is then created under `$DSH_SOURCE`, and `current` points at it. A clone anywhere on disk therefore converges on the same layout as a `curl` install, and the two paths share one worktree/exclude/lock/link sequence: they differ only in whether the repository was discovered by `git clone` or by `git rev-parse`.
 
-`$DSH_SOURCE/master.path` records the resolved repository, and only when that repository lives outside the container. A container holding its own master is self-contained and gets no file, so the file's presence is itself the signal that this container depends on an outside path: each staging worktree holds an absolute gitdir pointer into that clone, so deleting the clone breaks them.
+The installer records nothing about where that repository lives. A container whose repository sits outside it is not self-contained — each staging worktree holds an absolute gitdir pointer into that clone, so deleting the clone breaks them — but git already owns that fact: the worktree's `.git` file names the path, and `git worktree list` in the clone enumerates every worktree depending on it.
 
 Adoption branches from `HEAD`, so committed work is what runs and uncommitted changes stay in the checkout. This is not prompted or warned about: the installer builds the layout and gets out of the way. Setting `DSH_SOURCE` to a different directory remains the one documented way to opt back into cloning a separate tree.
 
-Every path comparison runs on physical paths through a `resolve_dir` helper, and every compared value is resolved at assignment rather than at the comparison. macOS resolves `/var` through a symlink to `/private/var`, so comparing a git-reported path against an unresolved one misclassified an existing managed install as a foreign clone and would have built a second container beside the real one. The same defect recurred twice more during review — once where a curl install's `REPO_ROOT` stayed unresolved and wrote a spurious `master.path`, and once where `x=$(resolve_dir …) || x=$fallback` left an empty path because the assignment succeeds even when the substitution fails. `resolve_dir` therefore echoes a missing path back itself, and callers that need "does not exist" test the directory explicitly. `git rev-parse --path-format=absolute` would do the same job but requires git 2.31+.

 The cost is that a contributor can no longer point PATH at a checkout and have `dsh` follow that working tree as they switch branches: the launcher now resolves to a staging worktree pinned to the `HEAD` adopted at install time. Re-running the installer adopts the current `HEAD` again.

 ## Testing
 
 `scripts/install.sh` has no automated test, and this change does not add one: the user directed that `install.spec.ts` be left out of scope. That is a known gap on a shipped user-facing path, and the `/var` resolution defect above is exactly the class of bug a test would have caught first. The standing [`FIXME(install-ts)`](../../../../scripts/install.sh) asking for this workflow to move into a tested TypeScript entrypoint is correspondingly more pressing.
 
-Verification was manual, through a throwaway harness driving the real script with a stubbed `pnpm`: adopting a standalone clone; adopting from a linked worktree into its existing container; an explicit `DSH_SOURCE` still opting back into cloning; a dirty tree adopting silently with no prompt or warning while its uncommitted file stays behind; a non-git checkout failing with guidance; and a `curl`-style clone install asserting both the built layout and the absence of `master.path`, which is the regression that caught the unresolved-`REPO_ROOT` defect. The interactive path was exercised under tmux from a dirty checkout, confirming the run reaches the launcher with no adoption prompt and ends with `dsh` running from the new staging worktree while the original checkout keeps its branch and its uncommitted file.

-`$DSH_SOURCE/master.path`记录解析出的仓库，且仅在该仓库位于容器之外时才记录。拥有自身 master 的容器是自包含的，不会生成该文件；因此该文件的存在本身就是一个信号，表明此容器依赖于外部路径：每个 staging worktree 都持有指向该克隆的绝对 gitdir 指针，删除该克隆就会破坏它们。

 接管以`HEAD`为分支起点，因此运行的是已提交的内容，未提交的更改仍留在检出中。这一点既不提示也不警告：安装器构建好布局后便不再打扰。把`DSH_SOURCE`设为其他目录，仍是唯一有文档记载的、回到克隆另一棵树的方式。

 `scripts/install.sh`没有自动化测试，本次变更也未添加：用户明确要求把`install.spec.ts`排除在范围之外。这是一条已交付的、面向用户的安装路径上的已知缺口，而上文那个`/var`解析缺陷，恰恰属于测试本应最先捕获的那类 bug。相应地，要求把这套流程迁移到有测试覆盖的 TypeScript 入口的既有[`FIXME(install-ts)`](../../../../scripts/install.sh)也变得更为紧迫。
 
-验证是手工完成的，通过一个一次性测试装置以打桩的`pnpm`驱动真实脚本：接管独立克隆；从 linked worktree 接管进其已有容器；显式`DSH_SOURCE`仍回到克隆路径；工作树不干净时静默接管、既不提示也不警告，且其未提交文件留在原处；非 git 检出失败并给出指引；以及`curl`式克隆安装同时断言所构建的布局和`master.path`的缺失——正是这项回归测试捕获了`REPO_ROOT`未解析的缺陷。交互路径在 tmux 下从一个不干净的检出走通，确认整个过程不出现接管提示即可到达启动器，最终`dsh`从新的 staging worktree 运行，而原检出保持其分支不变、未提交文件仍在。

Subject: [PATCH 289/557] docs(skills): the master clone may live outside the
 container

Adoption installs the master wherever the adopted clone already is, so
dsh-upgrade and dsh-customize can no longer state /master as fact.

Both skills already derive the master from the launcher, so the procedures
hold; only the layout description was wrong. dsh-upgrade now names
`git rev-parse --git-common-dir` as the way to resolve it.

The legacy-migration clauses stay: installs made before this change can
still link PATH straight at a worktree.

 clone
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

"Master clone" named the repository after a branch it need not be on. An
adopted clone keeps whatever branch it had — verified: adopting a clone
checked out on a feature branch leaves it there — so the name was wrong for
every install that did not come from curl.

Renamed to "main clone" in dsh-upgrade and dsh-customize, describing its
actual role: the one real clone whose object store every worktree shares.

dsh-upgrade also now says not to assume the main clone sits on `master` or
that its `origin` is authoritative upstream, since an adopted clone may
point at a fork. The fetch itself was already correct: step 1 resolves
authoritative upstream separately, and step 4 fetches upstream `master`
from it rather than from the clone's own branch.

Require the installed staging worktree to be clean and its `.agents/merge.lock` to exist and be Git-excluded. Never stash automatically.
-2. Treat the staging worktree behind the installed launcher as immutable for the whole attempt: do not touch its branch, HEAD, index, tracked or untracked files, dependencies, worktree registration, or lock file. Fetching into the shared master clone and creating new branches, worktrees, and private refs there are allowed because they are append-only and never alter the old worktree's checkout; opening and holding the existing lock is the only operation on the old worktree.

Confirm the main clone's `.git/info/exclude` excludes `.agents/merge.lock`, which the new worktree inherits.
 5. Inspect the Git log and commit ranges between the staging base, old staging tip, and fetched upstream tip. Identify incoming upstream changes, personal commits to preserve, likely duplicates, and conflict-prone areas before rebasing.
 6. In the new worktree, rebase the preparation branch onto the fetched upstream commit. Preserve intentional customizations and drop behavior already upstream. If upstream contains the customization and its remaining local diff only documents that customization, prefer upstream and drop the documentary diff rather than retaining a stale local account. Preserve documentation only when it adds a current, independently useful contract absent upstream. Abort without changing the installed launcher when resolution is uncertain.
 7. Install dependencies in the new worktree, review the resulting diff, and run the repository-required checks. Fix failures and rerun affected checks. Test the new worktree's `bin/dsh` directly.
-8. Point `dsh-staging/` at the validated prepared tip and check it out in the new worktree. Ensure its `.agents/merge.lock` exists (Git-excluded through the shared master exclude). Verify its branch, exact commit, clean status, remotes, dependencies, and absence of in-progress Git operations, then smoke its `bin/dsh` from a clean temporary workspace.

Record `current`'s pre-cutover target, then repoint `current` at the new staging worktree in one atomic swap with `ln -sfn` (the `-n` stops `ln` from dereferencing the existing directory symlink and writing the link inside the old worktree; `mv` behaves the same way and is unusable). Leave the PATH launcher alone once it already resolves through `current`; if a legacy install still links PATH straight at a worktree, create `current` and repoint PATH to `current/bin/dsh` as a one-time migration here. The `current` target must be a clean staging worktree on a staging branch and must never be the master clone or a preparation, feature, review, publication, or detached checkout.

On failure before the `current` cutover, leave `current`, the launcher, and the old worktree unchanged and remove only verified attempt artifacts created by this run (including the new worktree registration if empty). On failure during or after cutover, inspect `current`'s observed target before acting; if cutover did not verify, atomically repoint `current` back to its recorded pre-cutover target with `ln -sfn` and verify that `dsh` starts from the unchanged old staging worktree. This rollback is the sole exception allowing `current` to return to the old staging worktree. Never retry a side-effecting operation blindly.
 11. Release the old worktree's lock and tell the user to restart DSH through the installed launcher. The current process may continue from the old worktree, but no operation may mutate or remove it until the restarted process proves that it runs from `dsh-staging/` and the user confirms stability. Avoid customization integration during this confirmation window; if rollback is required after new work lands, reconcile that work explicitly rather than silently stranding it.

Subject: [PATCH 292/557] docs(skills): say how to resolve the main clone
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Both skills said to derive the main clone from the checkout without saying
how, and dsh-upgrade names dsh-customize as the owner of checkout discovery
— so the technique belonged there and was missing.

dsh-customize now gives it: `git rev-parse --git-common-dir` from the
checkout yields the shared git directory, whose parent is the main clone.
It also names the two ways to get this wrong — the answer is relative for a
plain clone, and paths must be compared physically, since macOS reaches
/var through a symlink to /private/var.

dsh-upgrade links to that procedure rather than restating it.

Verified against both shapes: an adopted clone outside the container, and a
curl-shaped install whose clone is at /master.

Subject: [PATCH 294/557] docs(skills): one canonical resolution, no DSH_SOURCE

DSH_SOURCE is an install-time shell variable the installer never exports, so
a skill reading ${DSH_SOURCE} at runtime reads nothing. Verified unset in a
running dsh process.

Git resolves the main clone identically for every install, so the curl-vs-
adopted distinction was never a branch point in these workflows. Verified
one launcher-then-Git recipe against three shapes: a curl install cloning
into the container, an adopted clone nested far outside any container, and
a custom DSH_SOURCE container.

dsh-customize now states that single procedure and warns off the installer
variables. dsh-upgrade's Layout describes what the resolution finds rather
than a path convention, and no longer teaches install shapes as cases.

These skills resolve the layout from the PATH launcher and Git, so how the
checkout was installed never enters the procedure. Describing install
shapes, the installer script, and its variables added detail a reader must
hold and would go stale whenever the installer changes.

Both skills now describe the observable state they resolve. The cases that
mattered survive as properties of that state: the main clone may sit
anywhere on any branch, and a launcher may link straight at a worktree with
no `current`.

 Routing them through YAML made them silently droppable. `@cordisjs/plugin-include` applies a targeted patch by replacing whole top-level keys (`target[key] = value`), so a personal `~/.dsh/config.yaml` patching the `tui-agent` entry's `config` replaces the shipped block entirely. A user overlay written to change provider and model therefore deleted every resume key it did not restate, and nothing reported it: absent `resumeCommand` legitimately means "no fallback configured".

Worse, the overlay carried `resumeSessionId: !!js process.env.RESUME_SESSION_ID` — a stale line from before [the env-var bridge was removed](../../archived/architecture/2026-07-24-dsh-commander-argument-adapter.md) — which overwrote the shipped `!!js "typeof resumeSessionId === 'string' ? …"` intake with a read of a variable nothing sets. `dsh --resume ` then started a *fresh* session and said nothing, reproduced directly: the banner showed a newly minted id, not the requested one. The [`dsh experimental-meta`](../feature/2026-07-28-dsh-meta-source-workspace.md) note had recorded this silent resume as an unexplained pre-existing defect; the overlay's shallow replacement is the cause.

 Identity belongs to `agent-loop` because that is the plugin which creates configured agents, and because a patch replaces a row's whole `config`: an overlay repointing the agent row's model route would erase a launcher-set identity key.

 **`ctx.provide` is the only channel from launcher argv into a Loader-mounted plugin.** Config `!!js` expressions evaluate as `with (entry.ctx) { eval(expr) }` (`vendor/loader/src/config/utils.ts`), so a bare identifier resolves against the entry's context and nothing else reaches it. The slot therefore cannot be removed while the app bundle is mounted from YAML; what changes is that it is now internal launcher↔app plumbing instead of a documented key a config author must wire correctly.

+`dsh migrate` and `dsh upgrade` boot the ordinary TUI as a fresh session whose first turn auto-invokes a bundled skill (`dsh-migrate`, `dsh-upgrade`), exactly as if the user typed `/skill:` and pressed Enter.
 
 The seed reuses the existing TUI skill path, not a new one. `createTuiChat` already has `invokeSkill(name, instructions)` — the code a typed `/skill:` runs, including the "Unknown skill" notice. The launcher passes the skill name to the TUI through a new boot-context slot `INITIAL_SKILL_KEY` (`tuiInitialSkill`), mirroring `CONFIGURED_AGENT_IDENTITIES_KEY`/`TUI_GOODBYE_MESSAGE_KEY`: `ctx.provide` is the only channel from launcher argv into a Loader-mounted plugin. The TUI's `apply()` reads the slot and folds it into `config.initialSkill`; after `ui.start()` succeeds, `createTuiChat` fires `invokeSkill(config.initialSkill, '')` once when set.
 
 **Freshness is gated in the launcher, not the TUI.** `runSkillSession` always mints a fresh session and provides the slot only when `resumeSessionId === undefined`, so a later `dsh --resume ` of that session is an ordinary TUI session with no re-injection. The TUI stays generic: it invokes whatever skill it is handed, once, at startup.
 
-**`migrate`/`upgrade` take no options.** Unlike `meta`, they carry no `--resume`, `--config`, or `-p`; a guided fresh-session entry has nothing to resume or reconfigure. Any leaked default-surface option fails loud, matching the `web`/`meta` rejection pattern in the Commander adapter. The two modes share one `SkillSessionInvocation` discriminant (`mode: 'migrate' | 'upgrade'`); `bin.ts` maps the mode to `dsh-${mode}`.

 **新鲜性在启动器而非 TUI 中把关。** `runSkillSession` 总是创建全新会话，且仅在 `resumeSessionId === undefined` 时提供该槽，因此之后 `dsh --resume ` 恢复该会话时是普通 TUI 会话，不会重复注入。TUI 保持通用：它只是把接到的 skill 在启动时调用一次。

+`dsh meta` boots the ordinary TUI with the harness checkout as the workspace, from any directory.
 
 The target is `SOURCE_ROOT` in `apps/cli/src/tui.ts` — `fileURLToPath(new URL('../../..', import.meta.url))`, three hops up from `apps/cli/{src,lib}` — the same constant the `harness:source` prompt section already names, so the workspace and the path advertised to the model cannot drift. It follows the launcher's real path, so a PATH symlink through `current` resolves to whichever staging worktree is active.

A camel-case external spelling or non-boolean invocation value drops the entire skill from discovery with a targeted warning; this pre-release repository does not keep an on-disk compatibility alias. Invocation data fails closed because ignoring it would default to permission and could expose the skill on a disabled surface, while wrong-typed optional `whenToUse` and `metadata` values are omitted because they do not decide invocation.

+# Agent Note: experimental subcommands gate behind `--experimental` or `DSH_EXPERIMENTAL=1`
+
+Status: implemented
+
+English | [中文](2026-07-31-experimental-subcommand-gate.zh.md)
+
+## Problem
+
+The `meta` and `upgrade` entry points carried their experimental status in their names: `dsh experimental-meta` and `dsh experimental-upgrade`. The prefix made every invocation verbose, and renaming a command at stabilization would break every reference to it — muscle memory, scripts, and docs alike. The status belongs in an opt-in gate, not in the name.
+
+## Decision
+
+`dsh experimental-meta` is `dsh meta` and `dsh experimental-upgrade` is `dsh upgrade`. Each runs only when the invocation passes its `--experimental` flag or the environment carries `DSH_EXPERIMENTAL=1`; otherwise the command fails loud on stderr with exit 1, naming both opt-ins. Per the pre-release stance, the old names are gone with no aliases, and `args.spec.ts` pins their rejection.
+
+The gate has two halves with one owner each. The per-invocation half is a Commander `--experimental` option on each experimental subcommand, checked inside its action after the leaked-parent-option rejection. The environment half is a boolean `parseDshArgs` parameter: `bin.ts` reads `process.env.DSH_EXPERIMENTAL === '1'` at the process boundary and passes the result down, so the parser stays a pure function of its inputs and the tests need no env mutation. `1` is the only enabling value — the variable is an explicit opt-in, not a truthiness check.
+
+Stabilizing a command later means deleting its `--experimental` option and `requireExperimental` call; the name does not move.
+
+## Alternatives considered
+
+**Keep the `experimental-` name prefix.** Rejected by the user's direction: the prefix taxes every invocation, and stabilization would be a breaking rename instead of deleting a gate.
+
+**A parent-level `--experimental` flag (`dsh --experimental meta`).** Rejected: the default surface is deliberately option-only with `enablePositionalOptions`, so parent options that leak across the subcommand boundary are treated as mistyped invocations. A parent flag consumed only by two subcommands would be exactly the leaked-option shape the adapter rejects everywhere else.
+
+**Read `process.env` inside `parseDshArgs`.** Rejected: the repo validates at the process boundary and keeps typed seams pure; tests would have to mutate and restore `process.env` around each case.
+
+**Accept any non-empty `DSH_EXPERIMENTAL`.** Rejected: the telemetry switch prefers off-by-mistake for a privacy control, but an experimental gate is an acknowledgement — `DSH_EXPERIMENTAL=0` must not enable the commands it names.
+
+## Consequences
+
+Daily invocations shorten to `dsh meta --experimental` and `dsh upgrade --experimental`, and a developer who sets `DSH_EXPERIMENTAL=1` in their environment gets the bare `dsh meta`/`dsh upgrade`. `dsh --help` marks both commands `(experimental)`. The gate costs one extra flag or env var until a command stabilizes, at which point the gate is deleted and the name is already final.

+# Agent Note：实验性子命令由 `--experimental` 或 `DSH_EXPERIMENTAL=1` 把守
+
+Status: implemented
+
+[English](2026-07-31-experimental-subcommand-gate.md) | 中文
+
+## Problem
+
+`meta` 与 `upgrade` 两个入口把实验性状态写在名字里：`dsh experimental-meta` 和 `dsh experimental-upgrade`。前缀让每次调用都变得冗长，而在稳定时重命名命令会破坏对它的所有引用——肌肉记忆、脚本与文档皆然。这种状态应当由一个显式选择加入的门槛承载，而不是由名字承载。
+
+## Decision
+
+`dsh experimental-meta` 改为 `dsh meta`，`dsh experimental-upgrade` 改为 `dsh upgrade`。二者只有在调用时传入各自的 `--experimental` 标志、或环境中带有 `DSH_EXPERIMENTAL=1` 时才会运行；否则命令在 stderr 上明确报错并以退出码 1 结束，同时指明两种选择加入方式。依据发布前立场，旧名称已移除且没有别名，`args.spec.ts` 钉住了对它们的拒绝。
+
+该门槛分为两半，各有其归属。按调用的一半是每个实验性子命令上的 Commander `--experimental` 选项，在其 action 内、泄漏父级选项的拒绝之后检查。环境的一半是 `parseDshArgs` 的一个布尔参数：`bin.ts` 在进程边界读取 `process.env.DSH_EXPERIMENTAL === '1'` 并向下传递结果，因此解析器保持为其输入的纯函数，测试也无需改动环境变量。`1` 是唯一的启用值——该变量是显式的选择加入，而不是真值判断。
+
+之后要稳定某个命令，只需删除它的 `--experimental` 选项和 `requireExperimental` 调用；名字不再变动。
+
+## Alternatives considered
+
+**保留 `experimental-` 名称前缀。** 按用户的指示拒绝：前缀让每次调用都付出代价，稳定时也会变成破坏性的重命名，而不是删除一个门槛。
+
+**父级 `--experimental` 标志（`dsh --experimental meta`）。** 拒绝：默认界面刻意保持纯选项形式并启用 `enablePositionalOptions`，跨子命令边界泄漏的父级选项都被视为拼错的调用。一个只被两个子命令消费的父级标志，恰恰就是适配器在其他所有地方都拒绝的泄漏选项形态。
+
+**在 `parseDshArgs` 内部读取 `process.env`。** 拒绝：本仓库在进程边界做验证，并保持类型化接缝的纯粹性；否则测试必须在每个用例前后修改并恢复 `process.env`。
+
+**接受任何非空的 `DSH_EXPERIMENTAL`。** 拒绝：遥测开关作为隐私控制倾向于误关而非误开，但实验性门槛是一种确认——`DSH_EXPERIMENTAL=0` 绝不能启用它所指名的命令。
+
+## Consequences
+
+日常调用缩短为 `dsh meta --experimental` 和 `dsh upgrade --experimental`；在环境中设置了 `DSH_EXPERIMENTAL=1` 的开发者可以直接使用 `dsh meta`/`dsh upgrade`。`dsh --help` 将这两个命令标注为 `(experimental)`。在命令稳定之前，门槛的代价是一个额外的标志或环境变量；稳定时删除门槛即可，名字已是最终形态。

-Argv is parsed once through a [Commander](https://github.com/tj/commander.js) adapter ([`src/args.ts`](src/args.ts)): one program whose default (no subcommand) is the TUI/headless surface (`--config`, `-p`/`--prompt`, `--resume`, `--dump-config`, `--dump-default-config`), whose `experimental-meta` subcommand is the same TUI over this checkout, whose `experimental-upgrade` subcommand is an option-less guided-session entry, and whose `web` subcommand is the browser UI. `src/bin.ts` switches on the resolved mode and dynamic-imports only that mode's module. `dsh --help` lists every mode and `dsh web --help` renders the web usage, `dsh --version` prints this app's version, and an unknown option or a mistyped `--resume` fails loud (stderr, exit 1) instead of misrouting. Every subcommand that shares no option with the default surface — `experimental-upgrade`, `web`, `experimental-meta` — rejects a leaked `--config`/`-p`/`--resume`/dump flag rather than running and dropping it. `dsh web`'s `--host`/`--port` are unvalidated pass-through overrides: the `dsh-host-webserver` schema is the single source of both the default (the shipped Web overlay value when a flag is absent) and validity, and rejects a bad value at boot. `--trusted-host` appends named authorities for the /api browser-trust fence; an all-interfaces bind additionally derives the machine's LAN IP literals itself ([`src/app-cli-entry.ts`](src/app-cli-entry.ts)), so the printed LAN URL works without flags.

 The TUI surface:
 
 - boots `base.cordis.yml` plus `tui.cordis.yml` through [`dsh-app-boot`](../../packages/ui/app-boot/README.md); `--config ` applies a patch-list overlay instead of the personal overlay, while `--config-replace ` boots that file as the complete tree;
 - resumes a persisted session with `dsh --resume ` and, when the Node host exposes `process.execve`, supplies the TUI's in-place handoff host: after selector preflight and current-session flush, the host disposes the app and replaces the process with a normalized resume invocation; runtimes without process replacement leave the session running and say so. This CLI owns session identity and the exit line rather than the config: it mints or selects the `main` session id and provides it, plus the exact command that reproduces this invocation, on the boot context ([`MAIN_SESSION_ID_KEY`](../../packages/ui/tui/README.md) and `TUI_GOODBYE_MESSAGE_KEY`). No `cordis.yml` key can drop resume, and a missing or unreadable id fails loud instead of creating a fresh session;
-- treats the **invoking directory** as the workspace — sessions, relative paths, and workspace instructions resolve from the cwd (`dsh experimental-meta` is the sole exception, below);
+- treats the **invoking directory** as the workspace — sessions, relative paths, and workspace instructions resolve from the cwd (`dsh meta` is the sole exception, below);
 - tells the agent where its own source lives: after boot it adds a prompt section naming this harness checkout, resolved from the launcher's real path so it holds under a PATH symlink and an arbitrary cwd, so the self-referential `cordis` toolset can read and modify it;
 - applies the personal overlay from `~/.dsh` (see [app-boot's Personal config](../../packages/ui/app-boot/README.md#personal-config)): `config.yaml` patches the booted tree, while `.env` there is the credential provider's own store (never hoisted into the environment, so keys stay rotatable). Environment precedence is ambient > project `.env`.
 - presents the [versioned first-run welcome](../../.agents/notes/implemented/feature/2026-07-30-versioned-tui-first-run-welcome.md) through the mounted TUI overlay service when its immutable marker is absent under `DSH_HOME`; only Enter creates that version's marker, while Escape, disposal, or process exit leaves it eligible. The official DeepSeek icon, responsive terminal rasters, all-locale Chinese copy, and notice version are static local owners; the overlay never writes a session event or model context.
 - registers bare `/compact`: while the agent is idle, it summarizes useful older history even below automatic pressure, rejects arguments, and reports success only after the standalone replacement bracket is durable. A prompt submitted during compaction keeps its queue identity and starts after that checkpoint; injected context remains visible.
 
-`dsh experimental-meta` is that same TUI with this harness checkout as the workspace, so working on dsh itself needs no `cd`. It chdirs to the checkout root — resolved from the launcher's real path, the same root the source-path prompt section names — after the environment is settled, so precedence is unchanged while the session cwd and HMR watch root move together. Experimental meta always starts a fresh session and accepts no default-surface options; use ordinary `dsh --resume ` to resume a persisted session.

Meta always starts a fresh session and accepts no default-surface options; use ordinary `dsh --resume ` to resume a persisted session.
 
-`dsh experimental-upgrade` is a guided fresh-session entry over the default TUI surface: it mints a fresh session in the invoking directory and seeds its first turn with the bundled `dsh-upgrade` skill, exactly as if the user typed `/skill:`. The launcher passes the skill name on the boot context ([`INITIAL_SKILL_KEY`](../../packages/ui/tui/README.md)), which the TUI auto-invokes once the chat is live. The command takes no options — `--config`, `-p`, and `--resume` fail loud — and seeds only on this first launch, so a later `dsh --resume ` of the session is an ordinary TUI session with no re-injection.

 `dsh --dump-config` and `dsh web --dump-config` print the composed config tree — the shipped base, the surface overlay, and the `--config` or personal overlay, exactly the layers that surface would boot — as YAML on stdout and exit without booting; `--dump-default-config` stops at the surface overlay, so diffing the two shows precisely what the user layer changes. Each run of rows is preceded by a `# ==` comment naming the file it comes from and the layers that patched it (e.g. `# == base.cordis.yml, patched by tui.cordis.yml`), so the output shows provenance while staying one loadable document. Composition runs through the include's own patch algorithm and YAML dialect (`applyEntryPatches`/`entryListSchema` from `@cordisjs/plugin-include`), so the dump cannot drift from what boots; `!!js` expressions print verbatim and unevaluated, and a patch whose target row is absent is reported on stderr with its layer, mirroring the Loader's boot-time warning. Launcher-owned boot-context values (session identity, CLI-flag patches) are per-invocation facts outside the config tree and do not appear. The dump flags reject boot-only flags (`-p`, `--resume`, `--config-replace`) rather than silently ignoring them, and `--dump-default-config` takes no `--config`.

 TUI 界面：
 
 - 通过 [`dsh-app-boot`](../../packages/ui/app-boot/README.md) 启动 `base.cordis.yml` 与 `tui.cordis.yml`；`--config ` 应用一个补丁列表覆盖并替代个人覆盖，而 `--config-replace ` 将指定文件作为完整配置树启动；
 - 使用 `dsh --resume ` 恢复已持久化会话。当 Node 宿主公开 `process.execve` 时，还会提供 TUI 的原地移交宿主：选择器预检并刷新当前会话后，宿主会释放应用，并以规范化的恢复调用替换进程；不支持进程替换的运行时会让会话继续运行并给出提示。会话身份与退出行由本 CLI 拥有，而非由配置指定：它创建或选定 `main` 会话 id，并把该 id 以及可复现本次调用的确切命令一起提供到启动上下文（[`MAIN_SESSION_ID_KEY`](../../packages/ui/tui/README.md) 与 `TUI_GOODBYE_MESSAGE_KEY`）。任何 `cordis.yml` 键都无法移除恢复能力；缺失或无法读取的 id 会明确报错，而不会创建新会话；
-- 将 **调用目录** 视为 workspace：会话、相对路径和 workspace 指令都从 cwd 解析（`dsh experimental-meta` 是唯一例外，见下文）；
+- 将 **调用目录** 视为 workspace：会话、相对路径和 workspace 指令都从 cwd 解析（`dsh meta` 是唯一例外，见下文）；
 - 告知 agent 自身源码所在位置：启动后添加一个命名此 harness checkout 的提示词段。该路径从启动器的真实路径解析，因此在 PATH 符号链接和任意 cwd 下仍然有效，使自指的 `cordis` 工具集可以读取并修改它；
 - 应用 `~/.dsh` 中的个人覆盖（参见 [app-boot 的个人配置](../../packages/ui/app-boot/README.md#personal-config)）：`config.yaml` 修补已启动的树，而那里的 `.env` 是凭据 provider 自己的存储（绝不会被提升进环境，因此密钥始终可轮换）。环境优先级为环境中已有的值 > 项目 `.env`。
 - 当 `DSH_HOME` 下不存在不可变确认标记时，通过已挂载的 TUI overlay 服务呈现[版本化首次运行欢迎页](../../.agents/notes/implemented/feature/2026-07-30-versioned-tui-first-run-welcome.md)；只有 Enter 会创建该版本的标记，Escape、资源释放或进程退出仍保留展示资格。官方 DeepSeek 图标、响应式终端栅格图、所有 locale 共用的中文文案和通知版本均由静态本地文件持有；overlay 不会写入会话事件或模型上下文。
 - 注册裸 `/compact`：agent 空闲时，即使未达到自动压力，也会摘要有效的较早历史；该命令拒绝参数，并只在独立替换标记对持久化后报告成功。压缩（compaction）期间提交的提示词保留其队列身份，并在该检查点之后启动；注入的上下文仍保持可见。
 
-`dsh experimental-meta` 是以本 harness checkout 为 workspace 的同一个 TUI，因此开发 dsh 自身无需 `cd`。它在环境确定之后才 chdir 到 checkout 根目录（从启动器的真实路径解析，与源码路径提示词段所指的根目录相同），因此环境优先级不变，而会话 cwd 与 HMR 监视根目录会一并移动。Experimental meta 始终创建新会话，不接受默认界面的任何选项；恢复已持久化会话应使用普通的 `dsh --resume `。

-`dsh experimental-upgrade` 是默认 TUI 界面之上的引导式全新会话入口：它在调用目录中创建一个全新会话，并以内置 `dsh-upgrade` skill 播种其首轮，效果等同于用户手动键入 `/skill:`。启动器将 skill 名称提供到启动上下文（[`INITIAL_SKILL_KEY`](../../packages/ui/tui/README.md)），TUI 在聊天就绪后自动调用它。该命令不接受任何选项——`--config`、`-p`、`--resume` 都会明确报错——且仅在首次启动时播种，因此之后 `dsh --resume ` 恢复该会话时是普通 TUI 会话，不会重复注入。

 `dsh --dump-config` 和 `dsh web --dump-config` 把合成后的配置树——已交付的基础配置、界面覆盖层，以及 `--config` 或个人覆盖层，恰好是该界面启动时组装的那些层——以 YAML 打印到 stdout 后退出，不启动任何东西；`--dump-default-config` 止步于界面覆盖层，因此对两份输出做 diff 就能精确看出用户层改了什么。每段连续的行之前都有一条 `# ==` 注释，标明该段来自哪个文件以及被哪些层修补过（例如 `# == base.cordis.yml, patched by tui.cordis.yml`），因此输出既展示来源，又仍是一份可加载的文档。合成通过 include 自己的补丁算法和 YAML 方言（`@cordisjs/plugin-include` 的 `applyEntryPatches`/`entryListSchema`）完成，因此 dump 不可能与实际启动漂移；`!!js` 表达式原样打印、不求值，目标行不存在的补丁会连同其所在层报到 stderr，与 Loader 启动时的警告一致。由启动器持有的启动上下文值（会话身份、CLI 标志补丁）是每次调用的事实，位于配置树之外，不会出现。dump 标志会拒绝仅用于启动的标志（`-p`、`--resume`、`--config-replace`）而不是静默忽略它们，`--dump-default-config` 不接受 `--config`。

Subject: [PATCH 299/557] fix(install): correct a false claim about shell
 assignment semantics
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review flagged the resolve_dir comment: it claimed `x=$(cmd) || fallback`
never fires "because the assignment succeeds even when the substitution
fails." That is wrong — command substitution propagates exit status and the
fallback does fire, confirmed in sh, bash, dash, and zsh.

Reproducing the original code shows the fallback also worked, so the second
"recurrence" the Agent Note described never existed. Both real defects were
the same one: comparing a resolved path against an unresolved one. The note
now says that instead of inventing a mechanism.

resolve_dir keeps its `|| printf` because it makes every caller a plain
assignment, so no site can compare against an empty path by forgetting its
own fallback — the reason is now stated accurately.

Also from review: REPO_COMMON is now resolved on both branches, matching
REPO_ROOT, and _repo_root notes why it is already physical without its own
resolve_dir call.

Subject: [PATCH 300/557] docs(install): the path bug is symlinks, not /var
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The comments and Agent Note blamed macOS resolving /var through
private/var. That is only how the mismatch surfaced in temp fixtures, since
mktemp hands back a /var path there.

The real condition is broader: Git always reports resolved paths, so
comparing one against an unresolved path disagrees whenever a symlink sits
anywhere above the checkout. A symlinked home directory alone triggers it —
reproduced with no /var involved — which is common wherever homes live
behind a symlink or on a network mount.

Naming the cause correctly keeps a reader from dismissing resolve_dir as
macOS-only defensiveness.

 Do not assume a path or branch name. DSH is usually installed from source with a personal staging branch; create one for the user only when none exists.

-2. Follow the launcher through the full symlink chain to reach the source checkout, then ask Git for everything else. The `dsh` on PATH is a symlink, usually through a stable `current` symlink into the active staging worktree; resolve the chain physically and take the launcher's parent directory as the checkout. Derive the rest from that checkout rather than from any path convention: `git -C  rev-parse --show-toplevel` confirms the checkout root, and `git -C  rev-parse --git-common-dir` gives the shared git directory — a linked worktree reports the real clone's, not its own — whose parent is the main clone, the one real clone whose object store every worktree shares. `--git-common-dir` answers relatively for a plain clone, so anchor it against the checkout before use, and resolve it physically: comparing a resolved path against an unresolved one silently misidentifies the clone, since macOS reaches `/var` through a symlink to `/private/var`. `git -C

    This resolves every checkout, so depend on nothing else: not an environment variable, not a container path, not the main clone's location or branch. A checkout whose launcher links straight at it, with no `current` in the chain, resolves the same way.
 3. Verify the checkout with Git, then record its branch, tip, status, remotes, worktrees, in-progress operations, and applicable `AGENTS.md` files.

 ## Markdown rendering

It omits raw HTML, neutralizes relative and non-HTTP(S)/mailto links, opens HTTP(S) links with safe external-link attributes, and renders image alt text without loading remote resources; `MessageText` remains the literal-text primitive for user-authored content. `extractMarkdownPlainText` removes Markdown presentation markup for compact labels while preserving raw HTML as literal text. Element spacing, tables, links, and inline code use the same `--dsw-alias-markdown-*` / `--dsw-font-markdown-*` tokens as deepsuite `@deepseek/md`. Fenced blocks render through `CodeBlock` (language banner, copy control, shiki for the registered grammars).

Subject: [PATCH 304/557] feat(fs-search): spawn the packaged ripgrep binary
 through the subprocess seam

glob/grep now run the @vscode/ripgrep binary via ctx.subprocess with a plain
argv vector: no system rg install, no shell layer, unconditional registration.
The load-time command -v rg probe and the bash-seam coupling are removed;
timeouts ride the cooperative exec.signal plus the seam's terminate
escalation. The fs-glob-sampling ACP snapshot executes the real packaged
binary against an mtime-pinned fixture. Adds the packaged-ripgrep-search
Agent Note, updates the roster-note facts and both shipped-composition e2es,
and regenerates the doc catalogs and third-party notices (surfacing
pre-existing manifest drift plus the new @vscode/ripgrep row; the notices
generator also learns pnpm 11's truncated virtual-store names).

+# Agent Note: Packaged ripgrep spawn for glob/grep
+
+Status: implemented
+
+English | [中文](2026-08-01-packaged-ripgrep-search.zh.md)
+
+> Supersedes [bash-backed grep/glob discovery](../../archived/feature/2026-07-09-bash-backed-grep-glob-discovery.md): the v1 decision's explicitly deferred alternative — directly spawning ripgrep — is now what ships.
+
+## Problem
+
+The `glob`/`grep` tools ran through the bash executor seam, which made a system `rg` install a host dependency. On Windows and container images there is no `rg` on `PATH` by default, so the tools silently vanished there; a deployment could only discover that from the load-time probe warning. The bash seam also forced the whole model-visible argument surface through one shell-quoting helper, because a shell sat between the tool and ripgrep — the [bash-backed note](../../archived/feature/2026-07-09-bash-backed-grep-glob-discovery.md) recorded that coupling as the v1 trade-off and named direct spawn as the reasonable follow-up if the shell-string domain ever proved too sensitive. It did: every model value had to survive POSIX single-quoting, the probe had to be scripted in tests, and the executor's own timeout classification duplicated what the cooperative tool-timeout policy already owns.
+
+## Decision
+
+`@deepseek-ai/dsh-tool-fs-search` now runs the PACKAGED ripgrep binary (`@vscode/ripgrep`, an npm dependency whose optional platform packages ship the binary) through the `ctx.subprocess` seam: `runRipgrep()` spawns `rgPath` with a plain argv vector, collect-mode stdout/stderr, `graceMs`, and `exec.signal` forwarded. There is no shell layer, so the shell-quoting boundary is gone from execution; `singleQuote` stays exported as a compatibility surface with its tests. Registration is unconditional — the load-time `command -v rg` probe and the conditional registration decision are deleted, and with them the "rg not found" warning. The package injects `tools`, `systemPrompt`, and `subprocess`.
+
+Exit semantics stay tool-owned: exit 0 is success with results, exit 1 is a successful empty search, anything else classifies into the existing `SEARCH_*` vocabulary (invalid pattern, launch failure, signal kill, raw-output overflow). Timeout is the cooperative tool-call budget attached to the tool definitions: `@deepseek-ai/dsh-timeout-policy` aborts `exec.signal`, the subprocess seam's terminate escalation provides the hard kill, and the tool reports `SEARCH_ABORTED`. The working directory is the session header cwd when present, else `process.cwd()` — there is no executor config to default through anymore, so the tool owns the fallback.
+
+The `fs-glob-sampling` ACP snapshot scenario now executes the real packaged binary against a prepared workspace whose fixed mtimes pin the `--sort=modified` order, replacing the PATH-injected `rg` stand-in (POSIX-only, because the displayed paths carry `/` separators the session-log comparison cannot normalize).
+
+## Alternatives considered
+
+**Keep the bash seam and probe, but document `rg` as a required host dependency.** Rejected: the host dependency is exactly the failure this change removes, and Windows support for the discovery tools was the point of the exercise; a documented requirement is still a requirement.
+
+**Make `rgPath` injectable (a config field or env override) so tests and snapshots keep substituting a stand-in binary.** Rejected: it adds a public deployment surface whose only consumer would be test seams, and the real binary is deterministic enough to pin directly through fixture mtimes — the packaged binary is the deployment, so tests should exercise it.
+
+**Switch to a pure-JS glob/search engine (e.g. `picomatch`/`tinyglobby`).** Rejected: the [dependency-swaps audit](../../rejected/simplification/2026-07-26-dependency-swaps-rejected-by-nih-audit.md) already rejected that on the "no glob engine exists" evidence; ripgrep semantics (`--sort=modified`, VCS pruning, JSON transport, regex dialect) are the tool contract.
+
+## Consequences
+
+- The discovery tools work on every platform the packaged binary covers (darwin/linux/win32, x64/arm64) with no host install; the shipped TUI/Web rosters gain `glob`/`grep` as fixed members ([even-out-shipped-tool-rosters](../feature/2026-07-31-even-out-shipped-tool-rosters.md)).
+- The shell-string attack surface is gone: hostile patterns are inert argv elements, pinned by the integration suite, which now runs on Windows too (it previously self-skipped without a system `rg`).
+- Load-time failure modes changed: a broken subprocess seam now fails the first search call (`SEARCH_FAILED`) instead of failing plugin load through the probe; a missing binary is a launch failure with the packaged path, not a PATH problem.
+- The integration suite's fixture dropped a filename Windows cannot represent (`"` in a name), keeping the suite replayable on every platform.

+# Agent Note: glob/grep 改用打包的 ripgrep 二进制直接 spawn
+
+Status: implemented
+
+[English](2026-08-01-packaged-ripgrep-search.md) | 中文
+
+> 取代 [bash 承载的 grep/glob 发现工具](../../archived/feature/2026-07-09-bash-backed-grep-glob-discovery.md)：v1 决策中明确延期的方案——直接 spawn ripgrep——现在成为实际交付的实现。
+
+## 问题
+
+`glob`/`grep` 工具经由 bash 执行器 seam 运行，这使系统 `rg` 安装成为宿主依赖。Windows 和容器镜像的 `PATH` 默认没有 `rg`，工具在那里会静默消失；部署方只能从加载期探针警告里发现这一点。bash seam 还迫使整个模型可见参数面经过一个 shell 引号工具，因为工具与 ripgrep 之间隔着一层 shell——[bash 承载决策](../../archived/feature/2026-07-09-bash-backed-grep-glob-discovery.md) 把这种耦合记为 v1 的取舍，并把直接 spawn 列为 shell 字符串域一旦被证明过于敏感时的合理后续。它确实被证明了：每个模型值都要经受 POSIX 单引号转义，探针要在测试里脚本化，执行器自身的超时分类还与协作式工具超时策略已有的职责重复。
+
+## 决策
+
+`@deepseek-ai/dsh-tool-fs-search` 现在运行 PACKAGED（打包的）ripgrep 二进制（`@vscode/ripgrep`，一个 npm 依赖，其可选平台包随附二进制），经由 `ctx.subprocess` seam：`runRipgrep()` 以纯 argv 向量 spawn `rgPath`，配以 collect 模式 stdout/stderr、`graceMs` 与转发的 `exec.signal`。不再有 shell 层，执行路径上的 shell 引号边界随之消失；`singleQuote` 作为兼容导出与其测试保留。注册变为无条件——加载期 `command -v rg` 探针与条件注册决策被删除，连同那条 "rg not found" 警告。本包注入 `tools`、`systemPrompt` 与 `subprocess`。
+
+退出语义仍由工具拥有：退出码 0 为有结果的成功，1 为成功的空搜索，其余归入既有 `SEARCH_*` 词汇（无效模式、启动失败、信号杀死、原始输出溢出）。超时是挂在工具定义上的协作式工具调用预算：`@deepseek-ai/dsh-timeout-policy` 中止 `exec.signal`，subprocess seam 的终止升级提供硬终止，工具报告 `SEARCH_ABORTED`。工作目录为会话 header cwd（存在时），否则为 `process.cwd()`——不再有执行器配置可供默认化，因此回退由工具自己拥有。
+
+`fs-glob-sampling` ACP 快照场景改为执行真实的打包二进制，作用于一个用固定 mtime 钉住 `--sort=modified` 顺序的预制工作区，取代 PATH 注入的 `rg` 替身（仅 POSIX：展示路径携带 `/` 分隔符，会话日志比较无法归一化）。
+
+## 备选方案
+
+**保留 bash seam 与探针，仅把 `rg` 记为必需宿主依赖。** 否决：宿主依赖正是本次改动要消除的失败模式，而让发现工具支持 Windows 正是此举的目的；写进文档的依赖仍是依赖。
+
+**让 `rgPath` 可注入（配置字段或环境变量覆盖），让测试与快照继续替换替身二进制。** 否决：这会新增一个只有测试 seam 会消费的公开部署面，而真实二进制本身足够确定——通过 fixture mtime 即可直接钉住；打包二进制就是部署形态，测试应当拿它来测。
+
+**改用纯 JS 的 glob/搜索引擎（如 `picomatch`/`tinyglobby`）。** 否决：[依赖替换审计](../../rejected/simplification/2026-07-26-dependency-swaps-rejected-by-nih-audit.md) 已基于"不存在 glob 引擎"的证据否决过该方向；ripgrep 语义（`--sort=modified`、VCS 剪枝、JSON 传输、正则方言）就是工具契约。
+
+## 后果
+
+- 发现工具在打包二进制覆盖的每个平台（darwin/linux/win32，x64/arm64）上开箱即用，无需宿主安装；交付的 TUI/Web 工具清单把 `glob`/`grep` 变为固定成员（见 [拉平交付的工具清单](../feature/2026-07-31-even-out-shipped-tool-rosters.md)）。
+- shell 字符串攻击面消失：恶意模式只是惰性 argv 元素，由集成套件钉住；该套件现在也在 Windows 上运行（此前没有系统 `rg` 时它自行跳过）。
+- 加载期失败模式改变：subprocess seam 损坏现在让首次搜索调用失败（`SEARCH_FAILED`），而非通过探针使插件加载失败；二进制缺失是带打包路径的启动失败，而不是 PATH 问题。
+- 集成套件的 fixture 去掉了 Windows 无法表示的文件名（名称含 `"`），保证套件在每个平台都能重放。

-The **model-facing filesystem discovery tools**—`glob`, `grep`—are backed by the **bash executor seam**, not by `ctx.fs` provider methods. At load, the package probes `command -v rg` through `ctx.bash`; if the executor cannot find ripgrep on its `PATH`, it logs a warning and registers no tools or prompt sections. Each call assembles a fixed ripgrep command (every model-controlled value through one package-private shell-quoting helper), runs it via `ctx.bash.resolve(request)` → `ctx.bash.run(spec)` as an ordinary foreground tool call, parses the raw `rg` output, and returns a workdir-relative canonical value. The package injects `tools`, `systemPrompt`, and `bash`—deliberately **not** `fs`; `ctx.spillStore` is read opportunistically with `ctx.get()` because formatted-result spill is optional.
+The **model-facing filesystem discovery tools**—`glob`, `grep`—are backed by the **packaged ripgrep binary** (`@vscode/ripgrep`), not by `ctx.fs` provider methods and not by a system `rg` install. Registration is unconditional: the binary ships inside the npm dependency, so there is no load-time availability probe. Each call spawns the binary through the `ctx.subprocess` seam with a fixed argv vector (model-controlled values are plain argv elements — no shell layer exists, so no quoting applies), parses the raw `rg` output, and returns a workdir-relative canonical value. The package injects `tools`, `systemPrompt`, and `subprocess`—deliberately **not** `fs`; `ctx.spillStore` is read opportunistically with `ctx.get()` because formatted-result spill is optional.

-Why bash-backed: local workspace discovery is naturally a process-backed `rg` workflow, and putting search on `ctx.fs` would force every filesystem backend to grow a search API. The bash executor owns request defaulting/capping, subprocess execution, process-group termination, environment scrubbing, raw output capture, and backend substitution (local, sandboxed, remote); this package owns schemas, argument validation, shell quoting, parsing, retention, formatted-result spill, and timeout declaration. The tools never call `ctx.bash.start()` and never expose a bash task id — the call returns only after `rg` exits, times out, is aborted, or fails.
+Why spawn-backed: local workspace discovery is naturally a process-backed `rg` workflow, and putting search on `ctx.fs` would force every filesystem backend to grow a search API. The subprocess seam owns spawn execution, process-tree termination, environment scrubbing, and bounded output capture; this package owns schemas, argument validation, argv construction, parsing, retention, formatted-result spill, and timeout declaration. The tools never expose a background task — the call returns only after `rg` exits, is terminated by the cooperative timeout, is aborted, or fails.
 
-## Deployment requirement: rg + co-located bash/filesystem
+## Deployment requirement: no host rg, co-located workdir/filesystem
 
-The mounted bash executor must be able to resolve `rg` from its `PATH` at plugin load; otherwise `glob` and `grep` are absent from the model-visible tool schema. Returned paths are displayed relative to the resolved bash workdir (the calling agent's session cwd when present, else the executor's configured default) and are follow-up-readable with `read` only when the bash workdir and the filesystem root are the same workspace. v1 documents that co-location requirement and performs no runtime cross-service validation; remote or virtual filesystem search waits for a shared workspace contract or a provider-specific search backend.
+The binary ships with the package on every supported platform (macOS/Linux/Windows, x64/arm64), so no host `rg` install is required and the tools register on every deployment.

 Routine budgets stay out of the model-facing schema (no `head_limit`/`offset`/`case_insensitive`/output modes): a model that needs surrounding context reads the matched file with `read`; one that needs later results follows the returned spill locator's retrieval hint.
 
 ## Two budgets, two artifacts
 
-Raw `rg` stdout is an internal transport detail. Each search requests `stdoutMaxBytes: rawOutputMaxBytes` from the bash seam and parses only complete retained stdout; if the executor still returns `stdout.truncated`, the search fails with `SEARCH_RAW_OUTPUT_OVERFLOW` and tells the model to narrow the query. A successful `glob` keeps the displayed search root and every acquired path in `{ root, paths }`; when sampling is enabled, `root` lets the Native renderer group an explicit relative or absolute search path by entries beneath that root rather than by its workdir prefix. `grep` keeps every acquired `{ path, lineNumber, line }` in `{ matches }`. Inline item and per-line preview caps apply only in the Native renderer. For a direct surface call with more logical results than the inline cap, post-policy best-effort saves the complete formatted preview through `ctx.spillStore.saveText()` and replaces only presentation with the configured page plus locator. Nested Code dispatches skip that spill because their full canonical value does not enter model context. Missing/failed spill keeps the inline page and reports that the complete result could not be saved—never an `isError`.

Model argument mistakes (blank pattern, a list-valued `include`) stay ordinary tool argument errors.

 ## Known Limitations and Deferred Work
 
-- **Search and file access have no shared-workspace proof** — returned paths are follow-up-readable only when the bash workdir and filesystem root denote the same workspace; the package performs no runtime cross-service validation.
-- **Ripgrep is a deployment dependency** — a missing `rg` executable makes the package register no tools or guidance; an incompatible executable or one that disappears after registration fails calls with `SEARCH_FAILED`. Remote or virtual filesystems need a co-located executor or another search consumer.
+- **Search and file access have no shared-workspace proof** — returned paths are follow-up-readable only when the workdir and filesystem root denote the same workspace; the package performs no runtime cross-service validation.
+- **The packaged binary is fixed at dependency version** — `@vscode/ripgrep` covers the platforms it ships (macOS/Linux/Windows, x64/arm64); an unsupported platform or a corrupted install fails calls with `SEARCH_FAILED`. Remote or virtual filesystems need a co-located workspace or another search consumer.
 - **The schemas expose one bounded page** — offset pagination, case-mode switches, alternate output modes, and provider-backed discovery remain outside this package; capped complete output requires a spill backend.
 - **Sampling, when enabled, groups by first path segment beneath the search root only** — an over-cap `glob` page balances across those top-level entries, so a result concentrated deeper (one busy directory inside an otherwise even tree) is still shown unevenly below that level; recursive balancing is deferred.

tool-fs-search no longer spawns rg from PATH after the packaged-binary

Subject: [PATCH 306/557] fix(scripts): normalize manifest glob paths in the
 notices generator

Node's fs.globSync returns OS-native separators: on Windows the
backslash paths failed the /-suffixed DEV_ONLY_AREAS prefix match in
tierExternalDeps, silently tiering dev-area manifests (test-runtime,
support/*, apps/*) as runtime dependencies. Normalize to / at
ingestion so the generated notices are platform-independent.

 - Load-time failure modes changed: a broken subprocess seam now fails the first search call (`SEARCH_FAILED`) instead of failing plugin load through the probe; a missing binary is a launch failure with the packaged path, not a PATH problem.
 - The integration suite's fixture dropped a filename Windows cannot represent (`"` in a name), keeping the suite replayable on every platform.
+- Regenerating `THIRD_PARTY_NOTICES.md` surfaced a latent generator bug the new dependency made visible: Node's `fs.globSync` returns OS-native separators, so on Windows the `/`-suffixed dev-area prefixes in the notices tiering never matched and dev-only packages (test tooling, support leaves) were mis-tiered as runtime. The generator now normalizes manifest paths at ingestion, and the notices are platform-independent.
+- The `@vscode/ripgrep` dependency adds its MIT row to the runtime tier, and pnpm 11's truncated virtual-store directory names needed a content-scan fallback in the notices generator's metadata lookup.

 - shell 字符串攻击面消失：恶意模式只是惰性 argv 元素，由集成套件钉住；该套件现在也在 Windows 上运行（此前没有系统 `rg` 时它自行跳过）。
 - 加载期失败模式改变：subprocess seam 损坏现在让首次搜索调用失败（`SEARCH_FAILED`），而非通过探针使插件加载失败；二进制缺失是带打包路径的启动失败，而不是 PATH 问题。
 - 集成套件的 fixture 去掉了 Windows 无法表示的文件名（名称含 `"`），保证套件在每个平台都能重放。
+- 重新生成 `THIRD_PARTY_NOTICES.md` 暴露了一个由新依赖带出的潜在生成器 bug：Node 的 `fs.globSync` 返回操作系统原生分隔符，因此在 Windows 上 notices 分层中带 `/` 后缀的 dev 区前缀永远匹配不上，dev-only 包（测试工具、support 叶子）被错分为 runtime。生成器现在在入口处归一化清单路径，notices 与平台无关。

The one-minute shipped budget covers an auxiliary DeepSeek Messages request plus server-side retrieval while leaving `dsh-tool-web`'s provider-neutral 30-second default unchanged for custom compositions.
 
 DeepSeek search uses the same `DEEPSEEK_API_KEY` credential reference as the official conversation adapter. The provider resolves that reference inside every search through the optional `ctx.credentials` service; only a composition without the seam falls back to the launching process environment, and a non-empty literal `apiKey` remains the programmatic last resort. A stored or rotated Web Models key therefore reaches the next search without restarting or retaining the value on the provider. Because `WebSearchProvider.available()` is synchronous, it treats an installed resolver as locally usable and missing dynamic credentials fail the operation with the provider-specific `WEB_PROVIDER_CREDENTIAL_MISSING` code while the stable tool schema stays registered.

 **Keep Web tools in `web.cordis.yml`.** Rejected because it preserves an unexplained tool-roster difference between TUI and Web/headless. The rows are not surface-specific, so `base.cordis.yml` is their one home; the [tool-roster decision](2026-07-31-even-out-shipped-tool-rosters.md) records the shared composition.

Search covers discovery; deployments that accept broader retrieval can opt into `dsh-web-fetch-local` and set `dsh-tool-web`'s `fetch` option to `true` in their overlay.
 
 ## Consequences
 
-Native model requests on every shipped surface carry only the `web_search` schema and search-only prompt guidance; Web/headless Code Mode exposes the same search capability beneath `run_code`. The prompt tells the model to use returned snippets and never advertises the disabled `web_fetch` tool. Search adds a complete auxiliary model call and may use the native server tool multiple times; its exact secret-free request remains reconstructable from the initiating session log. The default offers search-result snippets and source metadata but no arbitrary page retrieval; deployments that need full-page fetch must opt in. The Web snapshot lane boots the shipped tree, drives a replayed `web_search` call through the real DeepSeek provider against a local Messages fixture, asserts the durable auxiliary request and structured result, and pins the settled browser presentation. The TUI/Web composition smokes pin the shared `web_search` roster and absence of `web_fetch`; provider tests pin missing, stored, and rotated credential behavior plus literal and ambient compatibility.

 DeepSeek 搜索使用与官方会话适配器相同的 `DEEPSEEK_API_KEY` 凭据引用。提供方在每次搜索内部通过可选的 `ctx.credentials` 服务解析该引用；只有未挂载该 seam 的组合才会回退到启动进程的环境变量，非空的 `apiKey` 字面值仍作为程序化配置的最后兜底。因此，由 Web 的 Models 页存储或轮换的密钥无需重启即可用于下一次搜索，提供方也无需保留该值。由于 `WebSearchProvider.available()` 是同步方法，它会将已安装解析器视为本地可用；若动态凭据缺失，操作会以提供方专属错误码 `WEB_PROVIDER_CREDENTIAL_MISSING` 失败，而稳定的工具 schema 仍保持注册。

Subject: [PATCH 312/557] refactor(fs-search): apply #1119 review fixes to the
 packaged-rg spawn

- delete the singleQuote shell-quoting helper and its bash-spawning tests
  (no in-repo consumers; no shell layer exists anymore)
- drop spill from both collect streams: the tool never reads a raw spill
  path, and a lossy stdout read is a pure SEARCH_RAW_OUTPUT_OVERFLOW error
- prepend --no-config so a host RIPGREP_CONFIG_PATH cannot inject a --pre
  preprocessor into the unconfined spawn
- promote graceMs and stderrMaxBytes to validated Config fields (defaults
  SEARCH_GRACE_MS / SEARCH_STDERR_MAX_BYTES) instead of inheriting
  bash-local's config
- correct the grep tool's JSDoc seam reference (bash -> subprocess)
- drop the dead exit-127/command-not-found classification branch

There is no shell layer, so the shell-quoting boundary is gone from execution; `singleQuote` stays exported as a compatibility surface with its tests.

There is no shell layer, so the shell-quoting boundary is gone from execution; the `singleQuote` helper and its shell-spawning tests are deleted with it. The raw streams request the seam's diagnostic-tail collect shape (no spill files — the tool never reads a raw spill path; a lossy stdout read fails as `SEARCH_RAW_OUTPUT_OVERFLOW`). The terminate grace and the stderr tail budget are validated `Config` fields (`graceMs` default 3000, `stderrMaxBytes` default 64 KiB), no longer inherited from bash-local's config. Registration is unconditional — the load-time `command -v rg` probe and the conditional registration decision are deleted, and with them the "rg not found" warning. The package injects `tools`, `systemPrompt`, and `subprocess`.
 
 Exit semantics stay tool-owned: exit 0 is success with results, exit 1 is a successful empty search, anything else classifies into the existing `SEARCH_*` vocabulary (invalid pattern, launch failure, signal kill, raw-output overflow). Timeout is the cooperative tool-call budget attached to the tool definitions: `@deepseek-ai/dsh-timeout-policy` aborts `exec.signal`, the subprocess seam's terminate escalation provides the hard kill, and the tool reports `SEARCH_ABORTED`. The working directory is the session header cwd when present, else `process.cwd()` — there is no executor config to default through anymore, so the tool owns the fallback.

 - The shell-string attack surface is gone: hostile patterns are inert argv elements, pinned by the integration suite, which now runs on Windows too (it previously self-skipped without a system `rg`).
+- The spawn is unconfined (a plain `ctx.subprocess` call), so `--no-config` is prepended: a host `RIPGREP_CONFIG_PATH` (or an `rg.conf` beside the binary) can otherwise inject a `--pre` preprocessor that executes an arbitrary command for every matched file. With `--no-config`, no config file — and therefore no preprocessor — can reach the search.
+- The raw-output overflow path changed shape: the old bash-backed route inherited bash-local's always-on spill and could leave an unread multi-megabyte temp file; the subprocess seam now collects without spill, and overflow is a pure error (`SEARCH_RAW_OUTPUT_OVERFLOW`, "narrow pattern, path, or include and retry") with zero content returned.
 - Load-time failure modes changed: a broken subprocess seam now fails the first search call (`SEARCH_FAILED`) instead of failing plugin load through the probe; a missing binary is a launch failure with the packaged path, not a PATH problem.
 - The integration suite's fixture dropped a filename Windows cannot represent (`"` in a name), keeping the suite replayable on every platform.
 - Regenerating `THIRD_PARTY_NOTICES.md` surfaced a latent generator bug the new dependency made visible: Node's `fs.globSync` returns OS-native separators, so on Windows the `/`-suffixed dev-area prefixes in the notices tiering never matched and dev-only packages (test tooling, support leaves) were mis-tiered as runtime. The generator now normalizes manifest paths at ingestion, and the notices are platform-independent.

+- spawn 不受沙箱约束（普通的 `ctx.subprocess` 调用），因此前缀 `--no-config`：宿主的 `RIPGREP_CONFIG_PATH`（或二进制旁的 `rg.conf`）否则可注入 `--pre` 预处理器，对每个匹配文件执行任意命令。加上 `--no-config` 后，任何配置文件——因而任何预处理器——都无法触及搜索。
+- 原始输出溢出路径的形态改变：旧的 bash 承载路径继承了 bash-local 常开的 spill，可能留下没人读的多 MB 临时文件；subprocess seam 现在无 spill 收集，溢出是纯粹的错误（`SEARCH_RAW_OUTPUT_OVERFLOW`，"narrow pattern, path, or include and retry"），不返回任何内容。
 - 加载期失败模式改变：subprocess seam 损坏现在让首次搜索调用失败（`SEARCH_FAILED`），而非通过探针使插件加载失败；二进制缺失是带打包路径的启动失败，而不是 PATH 问题。
 - 集成套件的 fixture 去掉了 Windows 无法表示的文件名（名称含 `"`），保证套件在每个平台都能重放。
 - 重新生成 `THIRD_PARTY_NOTICES.md` 暴露了一个由新依赖带出的潜在生成器 bug：Node 的 `fs.globSync` 返回操作系统原生分隔符，因此在 Windows 上 notices 分层中带 `/` 后缀的 dev 区前缀永远匹配不上，dev-only 包（测试工具、support 叶子）被错分为 runtime。生成器现在在入口处归一化清单路径，notices 与平台无关。

Subject: [PATCH 313/557] test(fs-search): re-record the glob-sampling snapshot
 against the real API
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The scenario previously carried an authored fixture; W4 of #1119 review
requires a live transcript. Recording surfaced two composition bugs that
are fixed here alongside it:
- provider ids: the app and the replay catalog both named the old
  'deepseek' provider, which no adapter registers; both now use
  'deepseek-official'
- the live config lacked persistenceCompression: none, so record-mode
  sessions were written zstd-compressed and could not be harvested
  (the snapshot twin already forced plaintext)

Recorded logs also need deterministic replay:
- packChunks: false in both configs — the eager-drain batch boundaries
  that split packed delta runs are timing-dependent, so a packed log of
  a long reasoning stream cannot replay-match its live record
- the fixture's request/header config and request/context are normalized
  to the replay-produced minimal shape (the live adapter logs model
  capabilities llm-replay has no data for), and tool-result path
  separators are canonicalized to '/' for the Linux golden

posixOnly is restored now that the fixture is recorded.

Subject: [PATCH 314/557] test(fs-search): keep the glob-sampling fixture in
 canonical packed layout

The session-fixture-layout gate requires every session JSONL fixture in
the canonical packed layout (maximal delta runs per kind/block, as
migrate:packed-session-fixtures rewrites); the packChunks: false knob
violated that invariant and failed the snapshot job. Revert the knob and
canonicalize the recorded fixture instead: the live log's
eager-drain-packed rows migrate to the maximal-run layout a burst replay
reproduces, so the fixture stays replay-deterministic and canonical.

 ## Decision
 
-The shared Web/headless overlay (`apps/cli/config/web.cordis.yml`) supplies a concise coding-agent persona containing the resolved `{{model}}` and session `{{cwd}}`. `dsh web` additionally resolves the harness checkout from the launcher's module URL, installs the existing `harness:source` section, and adds an `app:web-surface` section before serving requests. The [source-checkout/workdir decision](2026-07-30-source-checkout-workdir-distinction.md) owns the source section's wording and its warning not to infer one path from the other.
+The shared Web/headless overlay (`apps/cli/config/web.cordis.yml`) supplies a concise coding-agent persona containing the resolved `{{model}}` and session `{{cwd}}`. `dsh web` additionally resolves the harness checkout from the launcher's module URL, installs the existing `harness:source` section, and adds an `app:web-surface` section before serving requests. The launcher registers that setup before mounting the config tree; its `systemPrompt` injection therefore installs both sections before later prompt consumers such as the agent loop can activate and emit a request header. The [source-checkout/workdir decision](2026-07-30-source-checkout-workdir-distinction.md) owns the source section's wording and its warning not to infer one path from the other.
 
 The Web section treats unqualified references to “this page,” “this GUI,” or “this app” as references to the DeepSeek Harness Web GUI. It also states that the browser provides no implicit DOM, route, or screenshot context, so the model can identify the product without claiming visual state it did not receive. The assembled text is logged in `request/header`, preserving the model-visible/logged invariant.
 
 ## Verification
 
-The keyless fresh-round-trip Web scenario boots the shipped base plus Web overlay, installs the same launcher context as `dsh web`, runs a real session through the HTTP/SSE application, and snapshots the first four system-prompt sections with source and working-directory paths normalized. The snapshot pins the harness identity, source checkout, Web orientation, and resolved coding-agent persona in request order.

 ## 决策
 
-`apps/cli/config/web.cordis.yml` 这份 Web／无头共享 overlay 提供一段简洁的编码 agent persona，其中包含解析后的 `{{model}}` 与会话 `{{cwd}}`。`dsh web` 还会根据启动器模块的 URL 解析 harness checkout，安装现有的 `harness:source` 提示词段，并在对外提供请求服务前添加 `app:web-surface` 提示词段。源码提示词段的措辞，以及其中不得从一条路径推断另一条路径的警告，均由另行记录的[源码 checkout 与工作目录区分决策](2026-07-30-source-checkout-workdir-distinction.md)负责。

 Web 提示词段把未限定的「这个页面」「这个 GUI」或「这个应用」解释为 DeepSeek Harness Web GUI。同时，它会明确说明浏览器不会隐式提供 DOM、路由或截图上下文，使模型能够识别产品，但不会声称掌握未收到的视觉状态。组装后的文本会记录在 `request/header` 中，从而保持「模型可见内容必须有日志记录」这一不变量。
 
 ## 验证
 
-无密钥的 Web fresh-round-trip 场景会启动已交付的 base 与 Web overlay，安装与 `dsh web` 相同的启动器上下文，并通过 HTTP／SSE 应用运行一个真实会话。测试会把源码路径和工作目录规范化，然后对系统提示词的前四个段落生成快照。该快照按请求顺序固定 harness 身份、源码 checkout、Web 界面定位，以及解析后的编码 agent persona。

Subject: [PATCH 317/557] fix(fs-search): address the second-round #1119 review

- inline the collect() identity wrapper now that both streams use the
  seam's diagnostic-tail shape
- resolve the packaged rg path lazily at the first call (memoized):
  @vscode/ripgrep resolves its platform package at module evaluation, so a
  static import turned a missing/corrupt platform package into a Loader
  composition failure instead of the documented per-call SEARCH_FAILED
- classify synchronous spawn-creation throws (a NUL in argv, an abort
  racing the pre-check, a rejected resolution) into SEARCH_FAILED /
  SEARCH_ABORTED instead of leaking raw errors
- correct the stderrMaxBytes contract: the stderr excerpt is embedded in
  SEARCH_* error messages, not hidden from the model
- export virtualManifest and pin its three acceptance paths (prefix hit,
  pnpm-11 truncated-name content-scan fallback, both miss) with fixture
  unit tests

Tests: rg-path.spec.ts (resolution failure + memoized rejection),
tools.spec.ts spawn-creation classification, notices spec virtualManifest.

 ## Decision
 
-`@deepseek-ai/dsh-tool-fs-search` now runs the PACKAGED ripgrep binary (`@vscode/ripgrep`, an npm dependency whose optional platform packages ship the binary) through the `ctx.subprocess` seam: `runRipgrep()` spawns `rgPath` with a plain argv vector prefixed by `--no-config`, collect-mode stdout/stderr, `graceMs`, and `exec.signal` forwarded. There is no shell layer, so the shell-quoting boundary is gone from execution; the `singleQuote` helper and its shell-spawning tests are deleted with it. The raw streams request the seam's diagnostic-tail collect shape (no spill files — the tool never reads a raw spill path; a lossy stdout read fails as `SEARCH_RAW_OUTPUT_OVERFLOW`). The terminate grace and the stderr tail budget are validated `Config` fields (`graceMs` default 3000, `stderrMaxBytes` default 64 KiB), no longer inherited from bash-local's config. Registration is unconditional — the load-time `command -v rg` probe and the conditional registration decision are deleted, and with them the "rg not found" warning. The package injects `tools`, `systemPrompt`, and `subprocess`.

There is no shell layer, so the shell-quoting boundary is gone from execution; the `singleQuote` helper and its shell-spawning tests are deleted with it.

The package injects `tools`, `systemPrompt`, and `subprocess`.
 
 Exit semantics stay tool-owned: exit 0 is success with results, exit 1 is a successful empty search, anything else classifies into the existing `SEARCH_*` vocabulary (invalid pattern, launch failure, signal kill, raw-output overflow). Timeout is the cooperative tool-call budget attached to the tool definitions: `@deepseek-ai/dsh-timeout-policy` aborts `exec.signal`, the subprocess seam's terminate escalation provides the hard kill, and the tool reports `SEARCH_ABORTED`. The working directory is the session header cwd when present, else `process.cwd()` — there is no executor config to default through anymore, so the tool owns the fallback.

 ## 决策
 
-`@deepseek-ai/dsh-tool-fs-search` 现在运行 PACKAGED（打包的）ripgrep 二进制（`@vscode/ripgrep`，一个 npm 依赖，其可选平台包随附二进制），经由 `ctx.subprocess` seam：`runRipgrep()` 以纯 argv 向量 spawn `rgPath`，向量前缀 `--no-config`，配以 collect 模式 stdout/stderr、`graceMs` 与转发的 `exec.signal`。不再有 shell 层，执行路径上的 shell 引号边界随之消失；`singleQuote` 工具与其 shell spawn 测试一并删除。原始流使用 seam 的诊断尾部 collect 形态（无 spill 文件——工具从不读取原始 spill 路径；lossy stdout 读取以 `SEARCH_RAW_OUTPUT_OVERFLOW` 失败）。终止宽限与 stderr 尾部预算成为经校验的 `Config` 字段（`graceMs` 默认 3000，`stderrMaxBytes` 默认 64 KiB），不再继承自 bash-local 的配置。注册变为无条件——加载期 `command -v rg` 探针与条件注册决策被删除，连同那条 "rg not found" 警告。本包注入 `tools`、`systemPrompt` 与 `subprocess`。

 退出语义仍由工具拥有：退出码 0 为有结果的成功，1 为成功的空搜索，其余归入既有 `SEARCH_*` 词汇（无效模式、启动失败、信号杀死、原始输出溢出）。超时是挂在工具定义上的协作式工具调用预算：`@deepseek-ai/dsh-timeout-policy` 中止 `exec.signal`，subprocess seam 的终止升级提供硬终止，工具报告 `SEARCH_ABORTED`。工作目录为会话 header cwd（存在时），否则为 `process.cwd()`——不再有执行器配置可供默认化，因此回退由工具自己拥有。

 ## Problem
 
-The demo apps mount `@cordisjs/plugin-hmr` as a leaf so a running agent picks up `cordis.yml` edits. One bad edit killed the process: `Include.refresh()` rethrew the YAML parse error, the HMR watcher awaits `refresh()` inside an async chokidar callback nobody catches, and the resulting unhandled rejection tripped `dsh-app-boot`'s fail-loud handler — `exit(1)` mid-session, losing the live TUI. Two adjacent defects made even *valid* reloads wrong: a file that parses to `undefined` (empty or mid-write truncated — editors and `sed -i` routinely produce these states) crashed the entry walk instead of reading as invalid, and a re-read never re-applied the include's `config.patches`, so any hot-reload of an overlay-based tree (Code Mode, personal overlays) silently reverted patched entries and removed inserted ones.
+An invalid `cordis.yml` edit must not kill a running agent, but preserving the process is insufficient when a valid-looking update partially replaces the Loader tree before a later entry fails. Callers also need to observe a rejected live update without treating the same error as an unhandled boot failure. Personal configuration adds a second requirement: HMR must observe one exact file outside its module roots, including a file or parent directory created after startup.
 
 ## Decision
 
-Harden the vendored `@cordisjs/plugin-include` (logged as local modification 8 in [vendor/README.md](../../../../vendor/README.md)) rather than the callers:
+The vendored Cordis lifecycle and Loader plugins provide an awaited, compensating config transaction, logged as local modifications 6, 8, and 9 in [vendor/README.md](../../../../vendor/README.md).
 
-- `refresh()` awaits the whole read-and-update and catches failures, logs a warning, and keeps the last good entry tree. A hot-reload is advisory; the invariant is that no file state reachable by an editor may take the process down.
-- `read()` rejects a non-array parse result with a `TypeError`, folding the `undefined`-parse case into the same "invalid file" signal, and commits `content`/`data` only after a successful parse — so reverting an edit to the exact last good content correctly reads as "unchanged".
-- `refresh()` and the `internal/update` listener apply `this.applyPatches(...)` before `root.update()`, restoring parity with `[Service.init]`. `applyPatches` deep-copies the cached parse (`structuredClone`) instead of mutating it, so repeated application converges and removing a patch reverts to the file's own values. The listener uses the incoming config's `patches` and persists that config itself: it vetoes the fiber restart (children update in place), and `Fiber.update` only assigns `this.config` behind `next()`, so without the explicit assignment the next re-read would re-apply the old overlay.
+`Fiber.update()` returns its `internal/update` waterfall result. Config validation remains synchronous, while the default continuation returns the restart promise. Loader entry updates can therefore distinguish validation, import, application, and rollback failure from successful lifecycle settlement. `EntryTree.await()` rechecks service-gated fibers after Loader tasks drain and rejects settled failures; a fiber waiting on an absent service remains a valid pending entry rather than making settlement hang.
 
-Boot-time behavior stays fail-loud and gets a sharper diagnostic: `[Service.init]` falls back to `initial` (or "config file not found") only on `ENOENT`; an existing-but-invalid file now fails with its real parse error instead of being mislabelled as absent or silently overwritten by `initial`.
+Loader imports a changed module name before disposing the active fiber. Candidate application is awaited; a failure disposes candidate effects and restores the prior plugin or config. Group reconciliation is sequential and restores earlier changed entries, additions, removals, and moves before rejecting. Persistence occurs only after successful programmatic mutation. This is a compensating transaction: lifecycle effects may be briefly visible, and a failed rollback is reported as an `AggregateError` rather than misrepresented as a retained tree.
+
+Include reads and validates detached candidate content, applies patches to a clone, reconciles the Loader tree, and only then commits cached content and parsed data. `refresh()` rejects to its caller after a parse, validation, application, or rollback failure. Initial load remains fail-loud; only an absent file may use `initial`. A non-array YAML/JSON result is invalid, and both file refresh and Include-config update re-apply patches without mutating the cached parse.
+
+HMR contains live refresh rejection. Its `registerConfig(filename, refresh)` method watches one exact path from the nearest existing ancestor, serializes and coalesces refreshes, and returns an async disposer that closes the watcher and drains active work. Both exact-path and ordinary config-file refreshes use that queue. A failure is normalized to `Error`, logged, and broadcast through the parallel `hmr/config-update-failed(filename, error)` event; rejecting observers are logged without stopping later refreshes. Creation, change, and removal are observed.
 
 ## Alternatives considered
 
-**Catch in the HMR watcher callback instead of `refresh()`.** Rejected: it would leave `refresh()` a trap for every other caller (the `internal/update` path shares the same tree-update logic), and it cannot fix the `undefined`-parse or patch-loss defects, which live inside the include.
+**Contain failures inside `Include.refresh()`.** Rejected because it prevents an HMR host from broadcasting the failure and still permits Loader reconciliation to hide partial application. Include owns candidate parsing and commit; HMR owns containment and observation.
 
-**Filter config-file rejections in `installFailLoud`.** Rejected: the fail-loud handler exists to make late load failures visible; teaching it to classify exceptions by origin would silently swallow genuine boot failures and leave the stale-`data` crash in place.
+**Restart the process for every config edit.** Rejected because Cordis effects already provide reversible plugin lifecycle, and a syntax error or failed optional plugin must not discard live sessions merely to recover the prior composition.
 
-**A PTY e2e proving the TUI survives a bad edit.** Rejected as the primary gate: the PTY smoke reads the repo's committed `cordis.yml`, so corrupting it in-place is not test-safe, and a temp copy cannot resolve the tree's bare package specifiers. The unit spec drives the exact `refresh()` entry point the watcher calls; the fix was additionally verified manually against the live TUI (bad YAML, empty file, restored file).
+**Promise invisible atomic replacement.** Rejected because arbitrary plugin effects cannot be snapshotted. Sequential application plus explicit compensation provides a stable final result without claiming that observers cannot see intermediate lifecycle transitions.
 
 ## Consequences
 
-- A bad `cordis.yml` edit now logs `ignoring config reload at ` and the agent keeps running on the last good tree; the next valid edit applies normally. With no logger exporter mounted in the TUI demos the warning is currently invisible on screen — surfacing loader warnings in the TUI is deferred.
-- Overlay trees survive base-file reloads with patches intact instead of silently reverting to the unpatched base.
-- The vendored include diverges further from upstream; the divergence is logged in the vendor manifest and re-applies on the next sync.
-- Known gap, out of scope here: the HMR watcher only handles chokidar `change` events, so editors that replace the file by rename (BSD `sed -i`, `git checkout`) do not trigger a config reload at all; and a reloaded app-entry config does not visibly restart the running TUI (pre-existing on the unmodified tree).
+- A failed live refresh rejects internally, retains or restores the last-good tree when compensation succeeds, and broadcasts one typed failure without becoming an unhandled rejection.
+- A rollback failure is visible and may leave an entry unavailable; the event and log do not claim otherwise.
+- Fibers waiting on declared dependencies remain valid pending entries: lifecycle settlement means no current work failed, not that every dependency exists.
+- Exact config watchers add filesystem resources only for registered paths and release them with their owning HMR fiber.
+- The vendored Loader, Include, HMR, and core event typing diverge further from upstream; the complete divergence is maintained in the vendor manifest.
 
 ## Testing
 
-`packages/ui/app-boot/tests/config-reload.spec.ts` boots real Loader trees against temp configs and pins: an invalid-YAML edit and an empty-file edit both resolve `refresh()` without rejection and keep the previous entry config; a subsequent valid edit applies; an overlay tree re-applies both entry patches and inserted entries on re-read; a hot-update of the include entry's own `patches` applies immediately, survives the next file re-read, and reverts cleanly when the patches are removed. The assertions fail on the unpatched vendored include.
+`packages/ui/app-boot/tests/config-reload.spec.ts` boots real temporary Loader/Include trees and covers parse and shape rejection, import-before-dispose, plugin/config restoration, multi-entry rollback, ancestor disablement, overlay convergence, option identity, failed direct-update persistence, and failed programmatic moves. `packages/ui/app-boot/tests/hmr-config.spec.ts` covers existing and missing exact paths, add/change/removal, serialized coalescing, disposal drainage, non-`Error` normalization, failure broadcast, and rejecting-observer containment. `packages/host/webserver/tests/webserver.spec.ts` proves a service-gated startup failure rejects Loader composition with its bind diagnostic, and `packages/typert/loader/tests/loader.spec.ts` exercises awaited programmatic removal through a real Loader consumer.

 ## Problem
 
-各示例应用把 `@cordisjs/plugin-hmr` 挂载为叶子配置项，让运行中的 agent 能感知 `cordis.yml` 的编辑。一次错误的编辑就会杀死进程：`Include.refresh()` 把 YAML 解析错误原样抛出，HMR 的文件监听器在一个无人捕获的异步 chokidar 回调里 await `refresh()`，产生的未处理 rejection 触发 `dsh-app-boot` 的快速失败处理器——会话中途 `exit(1)`，正在运行的 TUI 就此丢失。另有两个相邻缺陷让*合法*的重载也出错：解析结果为 `undefined` 的文件（空文件或写入中途被截断的文件——编辑器和 `sed -i` 常态性地产生这类中间状态）会让配置项遍历直接崩溃，而不是被判定为无效文件；并且重新读取时从不重新应用 include 的 `config.patches`，因此对基于 overlay 的配置树（Code Mode、个人 overlay）做任何热重载，都会悄悄把打过补丁的配置项回退、并把插入的配置项移除。
+无效的 `cordis.yml` 编辑不得杀死运行中的 agent（智能体）；但若一次看似有效的更新先部分替换 Loader 树，后续配置项才失败，仅仅保住进程仍不够。调用方还需要能观察到被拒绝的实时更新，同时不能让同一个错误被当作未处理的启动失败。个人配置还带来第二项要求：HMR（热模块替换）必须观察其模块根目录之外的一个确切文件，包括启动后才创建的文件或父目录。
 
 ## Decision
 
-加固 vendor 的 `@cordisjs/plugin-include`（在 [vendor/README.md](../../../../vendor/README.md) 中记录为本地修改第 8 条），而不是修改调用方：
+vendor 中的 Cordis 生命周期和 Loader 插件提供可等待、带补偿的配置事务，并在 [vendor/README.md](../../../../vendor/README.md) 中记录为本地修改第 6、8、9 条。
 
-- `refresh()` await 整个「读取并更新」过程并捕获失败，记录一条警告，并保留上一份完好的配置树。热重载是尽力而为的；不变式是编辑器可能产生的任何文件状态都不得导致进程退出。
-- `read()` 对非数组的解析结果抛出 `TypeError`，把 `undefined` 解析结果并入同一个「无效文件」信号，并且只在解析成功后才提交 `content`/`data`——因此把编辑撤销回与上一份完好内容完全一致时，会正确地判定为「无变化」。
-- `refresh()` 与 `internal/update` 监听器在 `root.update()` 之前调用 `this.applyPatches(...)`，与 `[Service.init]` 保持一致。`applyPatches` 对缓存的解析结果做深拷贝（`structuredClone`）而不是就地修改，因此重复应用会收敛，移除补丁会回退到文件自身的值。监听器使用传入配置中的 `patches` 并自行持久化该配置：它否决 fiber 重启（子配置项就地更新），而 `Fiber.update` 只在 `next()` 之后才赋值 `this.config`，若不显式赋值，下一次重新读取会重新应用旧的 overlay。
+`Fiber.update()` 返回其 `internal/update` waterfall（瀑布式事件）的结果。配置校验保持同步，而默认 continuation 返回重启 promise。因此，Loader 配置项更新可以区分校验、导入、应用和回滚失败，以及生命周期成功完成。`EntryTree.await()` 会在 Loader 任务排空后重新检查受服务门控的 fiber，并在 fiber 已结算为失败时 reject；等待缺失服务的 fiber 仍是有效的 pending 配置项，不会让结算挂起。
 
-启动期行为保持快速失败并获得更准确的诊断：`[Service.init]` 只在 `ENOENT` 时回退到 `initial`（或「config file not found」）；存在但无效的文件现在会以真实的解析错误失败，而不是被误标为文件缺失、或被 `initial` 静默覆盖。
+Loader 会先导入变化后的模块名，再 dispose（资源释放）活动 fiber。它会 await 候选项的应用；若失败，则 dispose 候选项的 effect，并恢复先前的插件或配置。组内对账按顺序进行，并会在拒绝前恢复此前已变更的配置项、添加项、移除项和移动项。只有程序化变更成功后才会持久化。这是一种补偿事务：生命周期 effect 可能短暂可见；回滚失败会报告为 `AggregateError`，而不会被误称为树已保留。
+
+Include 读取并校验尚未提交的候选内容，把补丁应用到其副本，对账 Loader 树，然后才提交缓存内容和解析数据。解析、校验、应用或回滚失败后，`refresh()` 会向调用方 reject。初始加载继续快速失败；只有文件不存在时才可以使用 `initial`。YAML/JSON 结果若不是数组即为无效；文件刷新和 Include 配置更新都会重新应用补丁，且不修改缓存的解析结果。
+
+HMR 收容实时刷新 rejection。其 `registerConfig(filename, refresh)` 方法从最近的现有祖先目录开始监听一个确切路径，串行化并合并刷新，并返回一个异步 disposer；该 disposer 会关闭 watcher 并排空活跃工作。确切路径和普通配置文件的刷新都使用此队列。失败会被规范化为 `Error`、记入日志，并通过并行事件 `hmr/config-update-failed(filename, error)` 广播；发生 rejection 的观察者会被记录，但不会阻止后续刷新。创建、变更和移除均会被观察。
 
 ## Alternatives considered
 
-**在 HMR 监听回调里捕获，而不是在 `refresh()` 里。** 否决：这会让 `refresh()` 继续成为其他所有调用方的陷阱（`internal/update` 路径共享同一套树更新逻辑），而且无法修复 `undefined` 解析结果与补丁丢失这两个位于 include 内部的缺陷。
+**在 `Include.refresh()` 内收容失败。** 已否决，因为这会使 HMR 宿主无法广播失败，却仍允许 Loader 对账掩盖部分应用。Include 负责候选内容的解析与提交；HMR 负责收容和观察。
 
-**在 `installFailLoud` 里过滤配置文件相关的 rejection。** 否决：快速失败处理器的存在意义就是让延迟出现的加载失败可见；教它按来源给异常分类会悄悄吞掉真正的启动失败，并且原样保留陈旧 `data` 导致的崩溃。
+**每次编辑配置都重启进程。** 已否决，因为 Cordis effect 已经提供可逆的插件生命周期，而语法错误或可选插件失败不应只为恢复先前的组合就丢弃正在进行的会话。
 
-**用 PTY e2e 证明 TUI 能在错误编辑后存活。** 否决其作为主要门禁：PTY 冒烟测试读取仓库中已提交的 `cordis.yml`，就地破坏它对测试不安全，而临时副本无法解析该配置树的裸包说明符。单元测试直接驱动监听器所调用的 `refresh()` 入口；此外还对运行中的 TUI 做了人工验证（错误 YAML、空文件、恢复文件）。
+**承诺不可见的原子替换。** 已否决，因为任意插件 effect 无法制作快照。按顺序应用并显式补偿可以得到稳定的最终结果，同时不会声称观察者看不到中间生命周期转换。
 
 ## Consequences
 
-- 现在错误的 `cordis.yml` 编辑会记录 `ignoring config reload at `，agent 继续运行在上一份完好的配置树上；下一次合法编辑正常生效。TUI 示例没有挂载任何日志导出器，这条警告目前不会显示在屏幕上——在 TUI 中呈现 loader 警告的工作暂缓。
-- overlay 配置树在基础文件重载后补丁保持完整，不再悄悄回退到未打补丁的基础配置。
-- vendor 的 include 与上游进一步分叉；该分叉已记录在 vendor 的 manifest 里，下次同步时重新应用。
-- 已知缺口，不在本次范围内：HMR 监听器只处理 chokidar 的 `change` 事件，因此通过重命名替换文件的编辑方式（BSD `sed -i`、`git checkout`）完全不会触发配置重载；应用配置项重载后也不会可见地重启运行中的 TUI（未修改的代码树上即已如此）。
+- 实时刷新失败会在内部 reject；补偿成功时会保留或恢复上一份完好的树，并广播一次类型化失败，而不会成为未处理的 rejection。
+- 回滚失败可见，并可能使一个配置项不可用；事件和日志不会误称其已恢复。
+- 等待已声明依赖的 fiber 仍是有效的 pending 配置项：生命周期完成只表示当前工作均未失败，而不表示每项依赖都存在。
+- 确切配置 watcher 只为已注册路径增加文件系统资源，并随其所属 HMR fiber 一起释放。
+- vendor 中的 Loader、Include、HMR 与核心事件类型定义进一步偏离上游；全部分叉均维护在 vendor manifest（元数据清单）中。
 
 ## Testing
 
-`packages/ui/app-boot/tests/config-reload.spec.ts` 用真实 Loader 树加载临时配置并固定以下行为：无效 YAML 编辑和空文件编辑都让 `refresh()` 正常 resolve 而不产生 rejection，并保留之前的配置项配置；随后的合法编辑正常生效；overlay 配置树在重新读取时重新应用配置项补丁和插入的配置项；对 include 配置项自身 `patches` 的热更新立即生效、在下一次文件重读后依然保持、并在补丁移除后干净地回退。这些断言在未打补丁的 vendor include 上会失败。
+`packages/ui/app-boot/tests/config-reload.spec.ts` 启动真实的临时 Loader/Include 树，并覆盖对解析和形状错误的拒绝、先导入再 dispose、插件/配置恢复、多配置项回滚、祖先禁用、overlay 收敛、option 对象身份、失败的直接更新不持久化以及失败的程序化移动。`packages/ui/app-boot/tests/hmr-config.spec.ts` 覆盖现有和缺失的确切路径、添加/变更/移除、串行化合并、dispose 排空、非 `Error` 值的规范化、失败广播以及对发生 rejection 的观察者的收容。`packages/host/webserver/tests/webserver.spec.ts` 证明受服务门控的启动失败会让 Loader 组合以其 bind 诊断 reject；`packages/typert/loader/tests/loader.spec.ts` 则通过真实 Loader 消费方演练可等待的程序化移除。

Disposal pairs `close()` with `closeAllConnections()` because held-open responses (SSE) never end on their own.
 
 In development, the client-plugin registry synchronously captures each built bundle's stat baseline before it returns, then polls those baselines and re-hashes changed content. Each rescan stages its candidate table, graph, and watch map before publishing them, so a baseline failure preserves the prior graph. An immediate rebuild therefore cannot disappear into an asynchronously established watch baseline; a rename window marks the path dirty, retains the last successful baseline, and forces a re-hash when the bundle reappears even with identical metadata.

 在开发环境中，客户端插件注册表会在返回前同步捕获每个已构建 bundle 的 stat 基线，随后轮询这些基线，并在内容变化后重新计算哈希。每次重新扫描都会先暂存候选表、图和监听 map，再统一发布，因此基线失败会保留先前的图。这样，即时重建不会消失在异步建立的监听基线中；重命名窗口会把路径标记为脏，保留最近一次成功基线，并在 bundle 重新出现时强制重新计算哈希，即使其元数据完全相同也不例外。

-Two Loader failure classes require separate guards because tree settlement propagates neither to its caller. A failed plugin import leaves a fiber-less entry that `assertEntriesLoaded` turns into a `boot()` rejection naming every unresolved plugin. A plugin callback or config failure leaves a failed fiber because `loader.await()` settles lifecycle tasks without propagating that error; `assertEntriesActivated` awaits the fiber explicitly and includes its original stack in the startup rejection. Before throwing, the audit marks those exact rejection reasons through one process checkpoint so `installFailLoud` coalesces Loader's duplicate notification while every unrelated unhandled rejection remains fatal.
+Loader settlement rejects import and lifecycle failures with the failing entry and stage; `boot()` disposes the partial context and wraps that failure with the bin name. Entries settlement leaves behind are audited separately: `assertEntriesLoaded` turns an enabled fiber-less entry into a rejection naming every unresolved plugin, and `assertEntriesActivated` awaits each failed fiber to include its original stack in the startup rejection and names each pending entry's unresolved services. Before throwing, the audit marks those exact rejection reasons through one process checkpoint so `installFailLoud` coalesces Loader's duplicate notification while every unrelated unhandled rejection remains fatal.
 
 Bare plugin specifiers in a config (`@deepseek-ai/dsh-*`, npm packages) resolve through the Cordis Loader's internal module loader. Repository bins install Loader's optional `node-addon-require-builtin` peer; external callers must supply it or install plugins where plain Node import resolution can find them. Relative specifiers resolve against the config directory without the native helper. The built `dsh-app-boot` artifact embeds the statically mounted Include implementation while leaving Loader external, so the include tree and host bind to one Loader peer. The `dsh` source launcher additionally maps manifest-declared workspace packages to their TypeScript source; its configuration gate requires every TUI/Web bare plugin to appear in the resolver manifest's `dependencies`. The bins' subprocess smokes exercise the internal-loader path, while this package's unit suite drives `boot()` in-process against configs with relative specifiers.

@@ -35,11 +35,12 @@ Keep this log exhaustive — every divergence from upstream must be listed.
 3. **All `tsconfig.json` files**: regenerated to extend the repo-root `tsconfig.base.json`, emit TypeScript intermediates to `lib/types`, and declare project references.
 4. **Vendored TypeScript source internal specifiers**: changed local relative imports/exports from upstream's specifier shape to explicit `.ts` specifiers so TypeScript rewrites emitted JS to `.js` while declarations keep explicit, NodeNext-safe `.ts` specifiers. This includes `loader/src/config/isolate.ts` using `declare module './entry.ts'`.
 5. **`schemastery/tsdown.config.ts` and `logger-console/tsdown.config.ts`**: ours, not upstream files — per-package build-shape overrides (dual ESM+CJS output; separate node/browser entries) for the repo-root tsdown build. They read the JS emitted under `lib/types` and then write the publish runtime entries under `lib/`. Like the regenerated tsconfigs, they are not part of the upstream sync surface.
-6. **`cordis/src/fiber.ts` lifecycle hardening**: locally closes three reentrant disposal gaps. An effect's owner-list wrapper is registered before its setup body runs, so an unload begun from inside setup awaits setup and every collected cleanup; synchronous setup failure removes the wrapper and rolls back collected cleanup. Async cleanup stays owner-visible until quiescence, and Cordis's internal effect composition joins an already-running cleanup while repeated public disposer calls retain their upstream single-shot result. Effect creation is rejected while the owner is `UNLOADING` (while `PENDING` and `LOADING` remain legal), preventing cleanup-time registrations from escaping the unload snapshot. Child fibers register and receive their parent-owned disposer before `internal/plugin` publication, resolve dependency declarations added by that notification before activation, drain effects attached while pending, skip plugin execution when reentrant disposal invalidates the load epoch before its first checkpoint, and contain teardown-notification failures per observer so one callback cannot starve peers or interrupt ownership cleanup.

 7. **`cordis/src/*.ts` JSDoc enrichment**: added `@param`/`@returns` tags and contract documentation (disposal semantics, waterfall veto, bail conditions, error cases) across the public plugin-author surface — `Context` (class, statics, and the `Context` interface properties incl. `root`), `EventsService`, `Fiber`, `RegistryService`, `ReflectService`, `Service`, `LoggerService` and their `declare module './context.ts'` overloads. Comment-only; no code changes. Motivation: the website API-reference generator renders these docs and hard-errors on undocumented members. Retire this entry when the enrichment is upstreamed to the fork.
-8. **`include/src/index.ts` hot-reload hardening**: `refresh()` awaits the full read-and-update and catches failures (logging a warning and keeping the last good entry tree) instead of rethrowing — upstream's throw escaped `@cordisjs/plugin-hmr`'s async watcher callback as an unhandled rejection, so one bad `cordis.yml` edit killed a live app. `read()` rejects a non-array parse result (an empty or mid-write truncated file parses to `undefined`, which upstream later crashed on) and commits `content`/`data` only on success, so reverting an edit to the exact last good content reads as "unchanged". `refresh()` and the `internal/update` listener re-apply `config.patches` before `root.update()`, matching initial load; upstream applied patches only in `[Service.init]`, so any config hot-reload silently reverted overlay-patched entries and removed inserted ones. `applyPatches` deep-copies via `structuredClone` instead of mutating the cached parse (repeated application converges; removing a patch reverts), and the veto-style `internal/update` listener persists the incoming config itself (`Fiber.update` only assigns behind `next()`), so later re-reads use the new patches. `[Service.init]` falls back to `initial` only on `ENOENT`; an existing-but-invalid file fails loud with its real parse error instead of "config file not found" (or a silent overwrite). `applyPatches` also indexes each `insert`ed entry as it is added, so a later patch in the same list can configure or disable a row an earlier patch inserted; upstream built the id index once before the patch loop, leaving inserted rows silently unpatchable. That matters because `dsh` composes one shared base (`apps/cli/config/base.cordis.yml`) with a surface overlay, an optional `--config` overlay, and the personal `~/.dsh/config.yaml` as sibling patch lists at one include level — patches never cross an include boundary, so surface-only rows would otherwise be unreachable from user config. Covered by `packages/ui/app-boot/tests/config-reload.spec.ts`.
-9. **Vendored Node-compatible TypeScript**: marked erased imports explicitly across `cordis`, `loader`, `include`, `hmr`, and `schemastery` so Node's native TypeScript transform does not request types as runtime exports. Schemastery's source uses an ESM default export and its package declares `type: module`; its built ESM/CJS entries retain explicit `.mjs`/`.cjs` extensions.
-10. **`include/src/index.ts` patch-semantics export**: extracted the private `applyPatches` body into the exported pure function `applyEntryPatches(data, patches, warn)` (the method delegates to it) and exported the `!!js` YAML dialect as `entryListSchema`, so `dsh --dump-config` composes and prints exactly what the include would mount without booting a tree. Behavior-preserving for mounting; the extraction exists because config tooling must never reimplement (and drift from) the patch algorithm.
+8. **Transactional Loader/Include config reconciliation**: Loader imports a changed entry name before disposal, awaits lifecycle settlement, and restores the previous plugin or config when candidate application fails. Loader settlement rechecks service-gated fibers after current tasks drain, rejects failures, and leaves fibers with absent dependencies pending. Group updates run sequentially, undo earlier changes and additions on failure, await removal, preserve programmatic option identity, and persist direct or tree-level mutations only after success. Include reads and validates detached candidate content, applies patches to a clone, reconciles the tree, and only then commits its cached content/data; direct refresh failures propagate for the caller to contain. A non-array parse is invalid, patches re-apply on every file or Include-config update, and initial content falls back to `initial` only on `ENOENT`. Covered by `packages/ui/app-boot/tests/config-reload.spec.ts` and `packages/host/webserver/tests/webserver.spec.ts`.
+9. **`hmr/src/index.ts` exact config watching**: `registerConfig()` watches one absolute config path outside module roots, including a path under missing parents, serializes and coalesces refreshes, and returns an async disposer that closes the watcher and drains active work. Refresh failures are normalized to `Error`, logged, and broadcast through the parallel `hmr/config-update-failed` event; observer failures are contained. Config-file changes discovered by the ordinary HMR watcher use the same serialized path. Covered by `packages/ui/app-boot/tests/hmr-config.spec.ts`.
+10. **Vendored Node-compatible TypeScript**: marked erased imports explicitly across `cordis`, `loader`, `include`, `hmr`, and `schemastery` so Node's native TypeScript transform does not request types as runtime exports. Schemastery's source uses an ESM default export and its package declares `type: module`; its built ESM/CJS entries retain explicit `.mjs`/`.cjs` extensions.
+11. **`include/src/index.ts` patch-semantics export**: extracted the private `applyPatches` body into the exported pure function `applyEntryPatches(data, patches, warn)` (the method delegates to it) and exported the `!!js` YAML dialect as `entryListSchema`, so `dsh --dump-config` composes and prints exactly what the include would mount without booting a tree.

 ## Consequences
 
 - The harness fully owns its framework layer: auditable, patchable, pinned — an RC upstream can't break us, and we can fix framework bugs in-tree.
+- Built packages execute the same vendored Cordis generation as source tests; removing workspace linking would silently substitute npm copies behind unchanged package names.
 - Upstream sync is manual (documented procedure in the manifest). The modification log keeps the diff surface known.
 - Vendored packages keep upstream code style; lint/strictness gates exclude them (their tsconfigs relax our newer compiler flags locally).
 - One local patch exists from day one: hmr's locale-YAML imports removed (the runtime YAML import hook isn't vendored).

 ## 后果
 
 - harness 完全持有其框架层：可审计、可打补丁、版本锁定。上游 RC 无法影响我们，框架 bug 可以在仓库内直接修复。
+- 构建后的包与源码测试执行的是同一版收录的 Cordis；移除 workspace 链接后，构建后的包会在包名不变的情况下静默改用 npm 副本。
 - 上游同步是手动操作（流程记录在 manifest 中）。修改日志使 diff 范围始终可知。
 - 收录的包保留上游代码风格；lint 与严格性门禁将其排除（它们的 tsconfig 在本地放宽了我们较新的编译器选项）。
 - 从第一天起就有一个本地补丁：移除了 hmr 的 locale-YAML 导入（运行时 YAML 导入钩子未被收录）。

 This directory contains source-vendored copies of the Cordis framework and its foundation libraries. They are copied into this monorepo instead of being depended on via npm, so that the harness fully owns its framework layer (auditable, patchable, pinned).
 
-All vendored packages keep their **original npm names** (they are resolved through pnpm workspaces) and are marked `private: true` — they are never published from this repo. Upstream MIT `LICENSE` files are preserved in each package directory.
+All vendored packages keep their **original npm names** and are marked `private: true` — they are never published from this repo. `pnpm-workspace.yaml#linkWorkspacePackages` makes matching upstream semver ranges resolve these pinned workspaces, including imports from built `lib/`; disabling it substitutes npm copies behind the same names. Schemastery's manifest additionally declares a conditional `exports` map (import → `.mjs`, require → `.cjs`): pnpm links the directory itself, so without `exports` Node's ESM resolver would fall back to `main` and load the CJS entry whose lazy `require('cosmokit')` can race ESM loading of the same linked module under module-hook hosts (vitest). Upstream MIT `LICENSE` files are preserved in each package directory.
 
 This file covers the manifest, the local-modification log, and the procedure for **updating** an existing vendored package. To **add a new** one, see the cookbook guide: [docs/cookbook/adding-a-vendored-package.md](../docs/cookbook/adding-a-vendored-package.md).

@@ -37,7 +37,7 @@ Keep this log exhaustive — every divergence from upstream must be listed.
 5. **`schemastery/tsdown.config.ts` and `logger-console/tsdown.config.ts`**: ours, not upstream files — per-package build-shape overrides (dual ESM+CJS output; separate node/browser entries) for the repo-root tsdown build. They read the JS emitted under `lib/types` and then write the publish runtime entries under `lib/`. Like the regenerated tsconfigs, they are not part of the upstream sync surface.
 6. **`cordis/src/fiber.ts` lifecycle hardening**: locally closes three reentrant disposal gaps. An effect's owner-list wrapper is registered before its setup body runs, so an unload begun from inside setup awaits setup and every collected cleanup; synchronous setup failure removes the wrapper and rolls back collected cleanup. Async cleanup stays owner-visible until quiescence, and Cordis's internal effect composition joins an already-running cleanup while repeated public disposer calls retain their upstream single-shot result. Effect creation is rejected while the owner is `UNLOADING` (while `PENDING` and `LOADING` remain legal), preventing cleanup-time registrations from escaping the unload snapshot. Child fibers register and receive their parent-owned disposer before `internal/plugin` publication, resolve dependency declarations added by that notification before activation, drain effects attached while pending, skip plugin execution when reentrant disposal invalidates the load epoch before its first checkpoint, and contain teardown-notification failures per observer so one callback cannot starve peers or interrupt ownership cleanup. `Fiber.update()` returns its `internal/update` waterfall result, allowing Loader callers to await a restart while preserving synchronous config validation.
 7. **`cordis/src/*.ts` JSDoc enrichment**: added `@param`/`@returns` tags and contract documentation (disposal semantics, waterfall veto, bail conditions, error cases) across the public plugin-author surface — `Context` (class, statics, and the `Context` interface properties incl. `root`), `EventsService`, `Fiber`, `RegistryService`, `ReflectService`, `Service`, `LoggerService` and their `declare module './context.ts'` overloads. Comment-only; no code changes. Motivation: the website API-reference generator renders these docs and hard-errors on undocumented members. Retire this entry when the enrichment is upstreamed to the fork.
-8. **Transactional Loader/Include config reconciliation**: Loader imports a changed entry name before disposal, awaits lifecycle settlement, and restores the previous plugin or config when candidate application fails. Loader settlement rechecks service-gated fibers after current tasks drain, rejects failures, and leaves fibers with absent dependencies pending. Group updates run sequentially, undo earlier changes and additions on failure, await removal, preserve programmatic option identity, and persist direct or tree-level mutations only after success. Include reads and validates detached candidate content, applies patches to a clone, reconciles the tree, and only then commits its cached content/data; direct refresh failures propagate for the caller to contain. A non-array parse is invalid, patches re-apply on every file or Include-config update, and initial content falls back to `initial` only on `ENOENT`. Covered by `packages/ui/app-boot/tests/config-reload.spec.ts` and `packages/host/webserver/tests/webserver.spec.ts`.

Covered by `packages/ui/app-boot/tests/config-reload.spec.ts` and `packages/host/webserver/tests/webserver.spec.ts`.
 9. **`hmr/src/index.ts` exact config watching**: `registerConfig()` watches one absolute config path outside module roots, including a path under missing parents, serializes and coalesces refreshes, and returns an async disposer that closes the watcher and drains active work. Refresh failures are normalized to `Error`, logged, and broadcast through the parallel `hmr/config-update-failed` event; observer failures are contained. Config-file changes discovered by the ordinary HMR watcher use the same serialized path. Covered by `packages/ui/app-boot/tests/hmr-config.spec.ts`.
 10. **Vendored Node-compatible TypeScript**: marked erased imports explicitly across `cordis`, `loader`, `include`, `hmr`, and `schemastery` so Node's native TypeScript transform does not request types as runtime exports. Schemastery's source uses an ESM default export and its package declares `type: module`; its built ESM/CJS entries retain explicit `.mjs`/`.cjs` extensions.
 11. **`include/src/index.ts` patch-semantics export**: extracted the private `applyPatches` body into the exported pure function `applyEntryPatches(data, patches, warn)` (the method delegates to it) and exported the `!!js` YAML dialect as `entryListSchema`, so `dsh --dump-config` composes and prints exactly what the include would mount without booting a tree. Behavior-preserving for mounting; the extraction exists because config tooling must never reimplement (and drift from) the patch algorithm. `applyEntryPatches` also indexes each `insert`ed entry as it is added, so a later patch in the same list can configure or disable a row an earlier patch inserted; upstream built the id index once before the patch loop, leaving inserted rows silently unpatchable. That matters because `dsh` composes one shared base (`apps/cli/config/base.cordis.yml`) with a surface overlay, an optional `--config` overlay, and the personal `~/.dsh/config.yaml` as sibling patch lists at one include level — patches never cross an include boundary, so surface-only rows would otherwise be unreachable from user config. Covered by `packages/ui/app-boot/tests/config-reload.spec.ts`.

@@ -37,7 +37,7 @@ Keep this log exhaustive — every divergence from upstream must be listed.
 5. **`schemastery/tsdown.config.ts` and `logger-console/tsdown.config.ts`**: ours, not upstream files — per-package build-shape overrides (dual ESM+CJS output; separate node/browser entries) for the repo-root tsdown build. They read the JS emitted under `lib/types` and then write the publish runtime entries under `lib/`. Like the regenerated tsconfigs, they are not part of the upstream sync surface.
 6. **`cordis/src/fiber.ts` lifecycle hardening**: locally closes three reentrant disposal gaps. An effect's owner-list wrapper is registered before its setup body runs, so an unload begun from inside setup awaits setup and every collected cleanup; synchronous setup failure removes the wrapper and rolls back collected cleanup. Async cleanup stays owner-visible until quiescence, and Cordis's internal effect composition joins an already-running cleanup while repeated public disposer calls retain their upstream single-shot result. Effect creation is rejected while the owner is `UNLOADING` (while `PENDING` and `LOADING` remain legal), preventing cleanup-time registrations from escaping the unload snapshot. Child fibers register and receive their parent-owned disposer before `internal/plugin` publication, resolve dependency declarations added by that notification before activation, drain effects attached while pending, skip plugin execution when reentrant disposal invalidates the load epoch before its first checkpoint, and contain teardown-notification failures per observer so one callback cannot starve peers or interrupt ownership cleanup. `Fiber.update()` returns its `internal/update` waterfall result, allowing Loader callers to await a restart while preserving synchronous config validation.
 7. **`cordis/src/*.ts` JSDoc enrichment**: added `@param`/`@returns` tags and contract documentation (disposal semantics, waterfall veto, bail conditions, error cases) across the public plugin-author surface — `Context` (class, statics, and the `Context` interface properties incl. `root`), `EventsService`, `Fiber`, `RegistryService`, `ReflectService`, `Service`, `LoggerService` and their `declare module './context.ts'` overloads. Comment-only; no code changes. Motivation: the website API-reference generator renders these docs and hard-errors on undocumented members. Retire this entry when the enrichment is upstreamed to the fork.
-8. **Transactional Loader/Include config reconciliation**: Loader imports a changed entry name before disposal, awaits lifecycle settlement, and restores the previous plugin or config when candidate application fails. Loader settlement rechecks service-gated fibers after current tasks drain, rejects failures, and leaves fibers with absent dependencies pending. Group updates run sequentially, undo earlier changes and additions on failure, await removal, preserve programmatic option identity, and persist direct or tree-level mutations only after success. Include reads and validates detached candidate content, applies patches to a clone, reconciles the tree, and only then commits its cached content/data; direct refresh failures propagate for the caller to contain. A non-array parse is invalid, patches re-apply on every file or Include-config update, an omitted patch list clears the overlay, and initial content falls back to `initial` only on `ENOENT`. Covered by `packages/ui/app-boot/tests/config-reload.spec.ts` and `packages/host/webserver/tests/webserver.spec.ts`.

 9. **`hmr/src/index.ts` exact config watching**: `registerConfig()` watches one absolute config path outside module roots, including a path under missing parents, serializes and coalesces refreshes, and returns an async disposer that closes the watcher and drains active work. Refresh failures are normalized to `Error`, logged, and broadcast through the parallel `hmr/config-update-failed` event; observer failures are contained. Config-file changes discovered by the ordinary HMR watcher use the same serialized path. Covered by `packages/ui/app-boot/tests/hmr-config.spec.ts`.

Subject: [PATCH 323/557] fix(review): label host-preparation failures and gate
 vendored lockfile links
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ds-review-bot round 1: boot() now throws `host preparation failed` when
prepare() rejects before any config-tree entry mounts (the plugin-tree label
overstated), and the new hygiene gate verify-vendored-links pins the
linkWorkspacePackages fix — every vendored package name in pnpm-lock.yaml
must resolve to a workspace link with no registry copy alongside.

+# Agent Note: Package-manager-native repository cache
+
+Status: implemented

+English | [中文](2026-07-30-package-manager-native-repository-cache.zh.md)
+
+## Problem
+
+A standalone Harness app cannot rely on a developer-owned SDK project to declare and install repository dependencies. Loading a configured GitHub repository therefore needs a persistent fetch, preparation, and cache boundary, but implementing Git transport, hosted-source syntax, package preparation, and a content store inside DSH would duplicate a package manager. Requiring a separately installed package manager would make a config-only feature depend on host setup.
+
+The cache also needs an update identity. A mutable branch name cannot both remain permanently cached and reflect later commits without an independent refresh protocol.
+
+## Decision
+
+Vendored `@cordisjs/plugin-loader/repository` exports `RepositoryCache`, a generic Node-only package helper with no DSH plugin-format knowledge. Keeping it on a subpath prevents browser consumers of the Loader's main entry from traversing Node filesystem and child-process imports. The caller supplies a package-manager-native source specifier and a cache root. DSH-specific callers own accepted source syntax, path selection, and the cache-root location; the [SDK project dependency workflow](../../proposed/feature/2026-07-17-sdk-follow-up-capabilities.md#external-cordis-plugin-installation) remains a separate path owned by the developer project's selected package manager.
+
+The Loader carries an exact runtime dependency on `pnpm@11.7.0` and invokes that package's JavaScript entry with the current Node executable. It never discovers a global executable or delegates through Corepack. Each cache miss creates an isolated project with one dependency named `repository`; pnpm owns Git/GitHub resolution, fetching, its content-addressed store, dependency installation, and lifecycle scripts in the repository's dependency graph.
+
+The isolated workspace sets `dangerouslyAllowAllBuilds: true`. A configured repository and its dependency graph are trusted executable code: lifecycle scripts may run before DSH reads any declared assets. The child receives ordinary host process state needed by Git and pnpm, but ambient credential-shaped (`KEY`, `PASSWORD`, `SECRET`, `TOKEN`) variables are removed. No OAuth, token forwarding, or private-repository authentication contract is added.
+
+The SHA-256 of the exact specifier names the cache entry. Concurrent same-process requests share one task. Installation occurs in a sibling temporary directory; only a successful install with a package directory and marker is atomically renamed into the final key. Failed staging is removed, and a competing process's already-published valid entry wins. A later process validates the marker and package directory before returning the stable `node_modules/repository` path.
+
+An identical specifier permanently reuses its published entry. The caller changes the ref or another part of the specifier to request a new generation; the cache does not poll remotes, reinterpret mutable refs, expire entries, or garbage-collect old generations.
+
+## Alternatives considered
+
+**Implement GitHub download, archive extraction, preparation, and caching directly.** Rejected under the [dependency policy](../process/2026-07-26-dependencies-over-hand-rolling.md): pnpm already owns hosted Git syntax, Git execution, lifecycle policy, and a shared content store. A second resolver would add more code while still needing package semantics.
+
+**Require `pnpm` on `PATH` or invoke Corepack.** Rejected because changing one app config must be sufficient on every supported installation. Pinning and shipping the CLI also makes the preparation policy reviewable and independent of the host's package-manager version.
+
+**Resolve a branch or tag again on every startup.** Rejected because it turns startup into a network refresh, changes code without a config diff, and makes rollback depend on remote state. Explicit ref changes preserve auditability even when a user deliberately chooses a mutable ref.
+
+**Disable repository lifecycle scripts.** Rejected because common plugin repositories need a declarative `prepare` step to validate and package their plugin subdirectory. The trust boundary is explicit configuration of executable source, not an incomplete illusion that only static files can run.
+
+**Introduce a Cordis repository service.** Rejected because cache lookup has no runtime contribution registry or provider variation. A small helper lets the later host own Cordis lifecycle and HMR without adding a service seam prematurely.
+
+## Consequences
+
+- Standalone apps carry pnpm's approximately 18.6 MB unpacked runtime instead of requiring a global tool or owning a Git/package implementation.
+- A repository author may use ordinary package preparation, and a malicious configured repository or dependency can execute code with the scrubbed child environment and the user's filesystem authority.
+- Exact specifiers make startup deterministic after the first successful install; changing cached code requires a config/ref change.
+- Failed installs leave no published cache entry and may be retried. Published corruption fails loud instead of silently reinstalling under the same identity.
+- Cache generations consume disk until a future explicit cache-management policy removes them.
+
+## Testing
+
+`packages/ui/app-boot/tests/repository-cache.spec.ts` covers same-process single-flight, cross-instance cache reuse, exact-specifier separation, failed-stage cleanup and retry, and boundary validation. Its real local-Git case invokes the bundled pnpm, runs the fixture repository's `prepare` script, and reads the prepared file from the installed cache entry without network access.

+# Agent Note: 包管理器原生仓库缓存
+
+Status: implemented
+
+[English](2026-07-30-package-manager-native-repository-cache.md) | 中文
+
+## 问题
+
+独立运行的 Harness 应用不能依赖开发者自有的 SDK 工程来声明并安装仓库依赖。因此，加载配置中的 GitHub 仓库需要一道持久的获取、准备与缓存边界；但如果在 DSH 内实现 Git 传输、托管来源语法、包（package）准备流程和内容存储，就会重复实现包管理器。若要求用户另行安装包管理器，则只需修改配置即可使用的功能还会依赖宿主环境的额外配置。
+
+缓存还需要明确更新标识。若没有独立的刷新协议，可变分支名无法既永久缓存，又反映后续 commit。
+
+## 决策
+
+vendor 中的 `@cordisjs/plugin-loader/repository` 导出 `RepositoryCache`：一个不包含 DSH 插件格式知识、仅限 Node 使用的通用包辅助工具。把它保留在子路径上，可以避免 Loader 主入口的浏览器消费方在解析依赖时遍历到 Node 文件系统和子进程 import。调用方提供包管理器原生的来源 specifier 和缓存根目录。DSH 专属调用方负责规定可接受的来源语法、路径选择与缓存根目录位置；[SDK 工程依赖工作流](../../proposed/feature/2026-07-17-sdk-follow-up-capabilities.md#external-cordis-plugin-installation)仍是另一条路径，由开发者工程选定的包管理器负责。
+
+Loader 将 `pnpm@11.7.0` 作为固定版本的运行时依赖，并使用当前 Node 可执行文件调用该包的 JavaScript 入口。它绝不探测全局可执行文件，也不经 Corepack 调用。每次缓存未命中都会创建一个隔离工程，其中只有一个名为 `repository` 的依赖；Git 与 GitHub 来源的解析和获取、pnpm 自身的内容寻址 store、依赖安装，以及仓库依赖图中的生命周期脚本均由 pnpm 负责。
+
+隔离工作区设置 `dangerouslyAllowAllBuilds: true`。用户配置的仓库及其依赖图都属于受信任的可执行代码：DSH 读取任何已声明资产之前，生命周期脚本就可能运行。子进程会收到 Git 与 pnpm 所需的常规宿主进程状态，但会移除环境中名称形似凭据（`KEY`、`PASSWORD`、`SECRET`、`TOKEN`）的变量。该机制不新增 OAuth、token 转发或私有仓库认证契约。
+
+缓存项以精确 specifier 的 SHA-256 命名。同一进程内针对相同 specifier 的并发请求共享一项任务。安装在同级临时目录中进行；只有安装成功且存在包目录和标记时，系统才会把暂存目录原子重命名为最终键对应的目录。失败的暂存目录会被删除；如果另一进程已发布有效项，则以该项为准。后续进程会先校验标记与包目录，再返回稳定的 `node_modules/repository` 路径。
+
+相同的 specifier 会永久复用已发布项。调用方通过修改 ref 或 specifier 的其他部分来请求新的缓存代次；缓存不会轮询远端、重新解释可变 ref、让条目过期，也不会垃圾回收旧代次。
+
+## 曾考虑的替代方案
+
+**直接实现 GitHub 下载、归档解压、准备与缓存。** 根据[依赖政策](../process/2026-07-26-dependencies-over-hand-rolling.md)不予采纳：pnpm 已负责托管 Git 语法、Git 执行、生命周期政策和共享内容存储。第二套解析器会增加更多代码，却仍需实现包语义。
+
+**要求 `pnpm` 位于 `PATH` 上，或调用 Corepack。** 不予采纳：在每种受支持的安装形态中，只修改一份应用配置就必须足以启用该功能。固定并随应用分发 CLI（命令行界面）还能使准备政策可供评审，并与宿主的包管理器版本无关。
+
+**每次启动都重新解析分支或 tag。** 不予采纳：这会把启动变成网络刷新，在配置 diff 未变化时更改代码，并让回滚依赖远端状态。即使用户有意选择可变 ref，显式修改 ref 仍能保持可审计性。
+
+**禁用仓库生命周期脚本。** 不予采纳：常见插件仓库需要声明式 `prepare` 步骤来校验并打包插件子目录。信任边界是显式配置可执行来源，而不是营造一种不完整的假象，仿佛只有静态文件能够运行。
+
+**引入 Cordis 仓库服务。** 不予采纳：缓存查找没有运行时贡献注册表，也不存在提供方变体。小型 helper 让后续宿主负责 Cordis 生命周期与 HMR（热模块替换），无需过早新增服务 seam。
+
+## 后果
+
+- 独立应用随附 pnpm 约 18.6 MB 的解压后运行时，不要求全局工具，也无需自行实现 Git 与包处理。
+- 仓库作者可以使用常规包准备流程；恶意的已配置仓库或依赖可以在经过上述清理的子进程环境中，以用户的文件系统权限执行代码。
+- 精确 specifier 使首次安装成功后的启动具有确定性；更改缓存代码必须修改配置或 ref。
+- 安装失败不会留下已发布缓存项，可以再次重试。已发布缓存损坏时会明确报错，而不会在同一标识下静默重装。
+- 缓存代次会持续占用磁盘，直到未来有明确的缓存管理政策将其移除。
+
+## 测试
+
+`packages/ui/app-boot/tests/repository-cache.spec.ts` 覆盖同进程 single-flight、跨实例缓存复用、精确 specifier 隔离、失败暂存清理与重试，以及边界校验。其真实本地 Git 用例会调用随附的 pnpm，运行 fixture（测试前置数据）仓库的 `prepare` 脚本，并在不访问网络的情况下，从已安装缓存项中读取准备后的文件。

@@ -39,8 +39,9 @@ Keep this log exhaustive — every divergence from upstream must be listed.
 7. **`cordis/src/*.ts` JSDoc enrichment**: added `@param`/`@returns` tags and contract documentation (disposal semantics, waterfall veto, bail conditions, error cases) across the public plugin-author surface — `Context` (class, statics, and the `Context` interface properties incl. `root`), `EventsService`, `Fiber`, `RegistryService`, `ReflectService`, `Service`, `LoggerService` and their `declare module './context.ts'` overloads. Comment-only; no code changes. Motivation: the website API-reference generator renders these docs and hard-errors on undocumented members. Retire this entry when the enrichment is upstreamed to the fork.
 8. **Transactional Loader/Include config reconciliation**: Loader imports a changed entry name before disposal, awaits lifecycle settlement, and restores the previous plugin or config when candidate application fails. Loader settlement rechecks service-gated fibers after current tasks drain, rejects failures, and leaves fibers with absent dependencies pending. Group updates start candidates concurrently, await every outcome, undo changes and additions on failure, await removal, preserve programmatic option identity, and persist direct or tree-level mutations only after success. Include reads and validates detached candidate content, applies patches to a clone, reconciles the tree, and only then commits its cached content/data; direct refresh failures propagate for the caller to contain. A non-array parse is invalid, patches re-apply on every file or Include-config update, an omitted patch list clears the overlay, and initial content falls back to `initial` only on `ENOENT`. Covered by `packages/ui/app-boot/tests/config-reload.spec.ts` and `packages/host/webserver/tests/webserver.spec.ts`.
 9. **`hmr/src/index.ts` exact config watching**: `registerConfig()` watches one absolute config path outside module roots, including a path under missing parents, serializes and coalesces refreshes, and returns an async disposer that closes the watcher and drains active work. Refresh failures are normalized to `Error`, logged, and broadcast through the parallel `hmr/config-update-failed` event; observer failures are contained. Config-file changes discovered by the ordinary HMR watcher use the same serialized path. Covered by `packages/ui/app-boot/tests/hmr-config.spec.ts`.
-10. **Vendored Node-compatible TypeScript**: marked erased imports explicitly across `cordis`, `loader`, `include`, `hmr`, and `schemastery` so Node's native TypeScript transform does not request types as runtime exports. Schemastery's source uses an ESM default export and its package declares `type: module`; its built ESM/CJS entries retain explicit `.mjs`/`.cjs` extensions.
-11. **`include/src/index.ts` patch-semantics export**: extracted the private `applyPatches` body into the exported pure function `applyEntryPatches(data, patches, warn)` (the method delegates to it) and exported the `!!js` YAML dialect as `entryListSchema`, so `dsh --dump-config` composes and prints exactly what the include would mount without booting a tree. Behavior-preserving for mounting; the extraction exists because config tooling must never reimplement (and drift from) the patch algorithm. `applyEntryPatches` also indexes each `insert`ed entry as it is added, so a later patch in the same list can configure or disable a row an earlier patch inserted; upstream built the id index once before the patch loop, leaving inserted rows silently unpatchable. That matters because `dsh` composes one shared base (`apps/cli/config/base.cordis.yml`) with a surface overlay, an optional `--config` overlay, and the personal `~/.dsh/config.yaml` as sibling patch lists at one include level — patches never cross an include boundary, so surface-only rows would otherwise be unreachable from user config. Covered by `packages/ui/app-boot/tests/config-reload.spec.ts`.
+10. **`loader/src/repository.ts`, `loader/tsdown.config.ts`, and the `@cordisjs/plugin-loader/repository` export**: the Node-only `RepositoryCache` installs one exact dependency specifier through the bundled `pnpm@11.7.0`, single-flights callers, and atomically publishes only a prepared package plus marker under the specifier hash. The subpath stays out of the browser-reachable Loader entry. Identical specifiers permanently reuse that entry; callers change the ref/specifier for another generation. The isolated workspace permits dependency build scripts because a configured repository is executable code, while the child drops ambient credential-shaped variables. Covered by `packages/ui/app-boot/tests/repository-cache.spec.ts`, including a keyless local-Git prepare run through the bundled pnpm.
+11. **Vendored Node-compatible TypeScript**: marked erased imports explicitly across `cordis`, `loader`, `include`, `hmr`, and `schemastery` so Node's native TypeScript transform does not request types as runtime exports. Schemastery's source uses an ESM default export and its package declares `type: module`; its built ESM/CJS entries retain explicit `.mjs`/`.cjs` extensions.

+# Agent Note: Static repository Plugin format
+
+Status: implemented
+
+English | [中文](2026-07-30-static-repository-plugin-format.zh.md)
+
+## Problem
+
+A repository that already contains reusable skills or an MCP server declaration should be usable by standalone Harness applications without becoming a Harness SDK project or rewriting its existing layout. Popular repositories must be able to add one `.dsh-plugin` directory while keeping their current skills and `.mcp.json` elsewhere in the tree. At the same time, treating an arbitrary repository entry point as a Cordis Plugin would make every repository a new unrestricted runtime extension surface and would bypass the existing skill and MCP lifecycle owners.
+
+The [package-manager-native repository cache](2026-07-30-package-manager-native-repository-cache.md) prepares an exact package source but intentionally knows nothing about DSH formats. This layer therefore needs a package-manager-compatible authoring format, a deterministic prepared artifact, and a Cordis composition that stays transactional under Loader disposal and replacement.
+
+## Decision
+
+`@deepseek-ai/dsh-repository-plugin` owns a restricted `.dsh-plugin` package format with two contribution kinds only: skill roots and one common `.mcp.json`. Its package metadata uses `package.json#dsh.skills` for relative skill-root paths and `package.json#dsh.mcpServers` for the relative MCP document path. At least one is required. Each path may leave `.dsh-plugin` to reuse repository content but must remain beneath the directory containing that `.dsh-plugin`; a nested selectable Plugin therefore owns the adjacent subtree above its package without gaining access to unrelated host paths.
+
+The `.dsh-plugin` package declares `dsh-plugin-prepare` as its ordinary package-manager `prepare` script. The helper validates metadata and source types, strictly parses `.mcp.json`, copies static assets into `dsh-plugin-assets`, and writes `dsh-plugin.mjs`. The `.mjs` extension avoids imposing `type: module` on repository-authored package metadata. The generated module is a fixed import-free template containing only a normalized manifest, `inject = ['loader']`, and delegation to the `dsh-repository-plugin` Loader builtin. Preparation never discovers, transpiles, bundles, or preserves a custom repository entry point.
+
+Loading the DSH package registers that builtin as an effect. A generated wrapper mounts the builtin as its child with `import.meta.url`, so all contributions belong to the wrapper fiber and disappear on Loader removal or rollback. The builtin revalidates the prepared manifest and path containment before reading assets. It composes the existing implementations rather than registering skills or MCP tools itself.
+
+Each prepared skill set mounts `dsh-skill-local` with a unique `repository:` provider name, only the copied custom roots, and watching disabled. `dsh-skill-local` therefore gains two general configuration fields: `providerName` and `includeDefaultRoots`. Their defaults preserve its existing single local provider; repository instances set a distinct name and exclude project/user roots so multiple instances neither collide nor duplicate host-local discovery.
+
+Each `.mcp.json` server becomes one existing `dsh-mcp-client` child. The adapter accepts the common root `{ "mcpServers": ... }`; stdio definitions allow only optional `type: "stdio"`, `command`, `args`, and `env`, while HTTP definitions allow only `type: "http"`, `url`, and `headers`. Exact `${NAME}` process-environment references expand at runtime, after cache preparation; missing names fail Plugin load. HTTP maps to the client's Streamable HTTP transport, and stdio uses the prepared package directory as `cwd`. The existing client alone owns connection attempts, failure logging, remote tool synchronization, tool calls, and disconnects. Consequently an MCP connection failure keeps its established successful-plugin/no-tools behavior and is not reclassified as a repository preparation or Loader failure.
+
+Unknown MCP fields reject. This intentionally excludes OAuth, `auth` objects, `CLAUDE_PLUGIN_ROOT`, and a broader Claude compatibility contract. Hooks, commands, agents, apps, arbitrary Cordis code, marketplaces, and discovery are also unsupported. Repository subdirectory selection and GitHub configuration belong to the later app/cache integration, not this format package.
+
+## Alternatives considered
+
+**Load a repository's own Cordis entry point.** Rejected because it makes the advertised static format an unrestricted code-loading API, requires repository authors to depend on Harness internals, and duplicates the ordinary SDK/plugin-dependency path.
+
+**Teach generated wrappers to implement skills and MCP directly.** Rejected because copied runtime code would drift from `dsh-skill-local` and `dsh-mcp-client`, especially their provider invalidation, tool synchronization, failure, and teardown contracts.
+
+**Import Harness packages from each generated wrapper.** Rejected because repository packages should not resolve or version the application's internal dependency graph. A Loader builtin supplies one app-owned implementation and keeps generated wrappers import-free.
+
+**Watch prepared repository assets.** Rejected because an exact repository cache generation is immutable. Ref, subdirectory, or configuration changes select a new generation; a second watcher would create an unowned refresh identity.
+
+**Treat MCP connect failures as Loader update failures.** Rejected because the existing MCP client deliberately contains connect failures and exposes no tools. Changing that semantic only for repository sources would create two failure contracts for the same server configuration.
+
+## Consequences
+
+- Existing skill/MCP repositories can add a small `.dsh-plugin/package.json` without relocating their assets or adopting an SDK project.
+- Prepared output is deterministic static glue, while the configured repository and its dependency lifecycle remain trusted executable package-manager input rather than a sandbox.
+- Multiple repository Plugins coexist through provider names and ordinary MCP server-name uniqueness; duplicate names fail through their existing registries and participate in Loader rollback.
+- Cached source edits do not appear live. Another exact source/ref/path/config selection is required.
+- Adding another contribution kind requires an explicit format and DSH-owned runtime consumer; it cannot arrive as repository JavaScript by accident.
+
+## Testing
+
+Focused tests prepare skills and MCP metadata, prove the emitted wrapper contains no imports, reject Work IQ-style OAuth fields, map Expo-style HTTP and DataJunction-style stdio plus environment values, and exercise missing variables. A real Loader test mounts a generated wrapper through the registered builtin, reads its skill through `ctx.skills`, removes the Loader entry, and observes provider cleanup. The keyless headless example loads a checked-in prepared wrapper through its real `cordis.yml` and snapshots the repository skill's logged model catalog row.

+# Agent Note：静态 repository Plugin 格式
+
+状态：已实现
+
+[English](2026-07-30-static-repository-plugin-format.md) | 中文
+
+## 问题
+
+一个已经包含可复用 skills 或 MCP server 声明的仓库，应当能被独立 Harness 应用使用，而不必先变成 Harness SDK 项目，也不应被迫改写现有布局。常见仓库只需新增一个 `.dsh-plugin` 目录，同时仍可把原有 skills 与 `.mcp.json` 放在仓库其他位置。与此同时，如果把任意仓库入口都当作 Cordis Plugin，就会让每个仓库成为新的无限制运行时扩展表面，并绕过现有的 skill 与 MCP 生命周期所有者。
+
+[Package-manager-native repository cache](2026-07-30-package-manager-native-repository-cache.md) 会准备一个精确 package source，但有意不了解任何 DSH 格式。因此本层需要一种兼容 package manager 的创作格式、确定性的已准备产物，以及在 Loader dispose 和替换期间仍保持事务性的 Cordis 组合。
+
+## 决策
+
+`@deepseek-ai/dsh-repository-plugin` 负责一个受限的 `.dsh-plugin` package 格式，且只允许两类贡献：skill 根和一个通用 `.mcp.json`。Package metadata 使用 `package.json#dsh.skills` 声明相对 skill 根路径，使用 `package.json#dsh.mcpServers` 声明相对 MCP 文档路径；两者至少需要一个。路径可以离开 `.dsh-plugin` 以复用仓库内容，但必须留在包含该 `.dsh-plugin` 的目录之下；因此，一个嵌套且可选择的 Plugin 可以拥有其 package 上方相邻的子树，却不能访问无关宿主路径。
+
+`.dsh-plugin` package 把 `dsh-plugin-prepare` 声明为普通 package-manager `prepare` 脚本。Helper 会校验 metadata 与源码类型，严格解析 `.mcp.json`，把静态资源复制到 `dsh-plugin-assets`，并写入 `dsh-plugin.mjs`。`.mjs` 扩展名避免强迫仓库作者在 package metadata 中设置 `type: module`。生成模块来自固定、无 import 的模板，只包含规范化 manifest、`inject = ['loader']`，以及对 `dsh-repository-plugin` Loader builtin 的委托。准备阶段永远不会发现、转译、打包或保留自定义仓库入口。
+
+加载 DSH package 会以 effect 方式注册该 builtin。生成的包装模块使用 `import.meta.url` 把 builtin 挂载为自己的子级，因此所有贡献都归属于包装 fiber，并在 Loader 移除或回滚时消失。Builtin 会在读取资源前重新校验已准备 manifest 与路径包含关系。它只组合现有实现，而不自行注册 skills 或 MCP 工具。
+
+每份已准备 skill 集合都会挂载 `dsh-skill-local`，使用唯一的 `repository:` 提供方名称、仅包含复制后的自定义根，并禁用监视。因此 `dsh-skill-local` 新增两个通用配置字段：`providerName` 和 `includeDefaultRoots`。默认值保持原有单一本地提供方行为；repository 实例设置不同名称并排除项目／用户根，使多个实例既不冲突，也不会重复宿主本地发现。
+
+`.mcp.json` 中的每个 server 都变成一个现有 `dsh-mcp-client` 子级。适配层接受通用根对象 `{ "mcpServers": ... }`；stdio 定义只允许可选的 `type: "stdio"`、`command`、`args` 与 `env`，HTTP 定义只允许 `type: "http"`、`url` 与 `headers`。严格的 `${NAME}` 进程环境变量引用在运行时、cache 准备之后展开；缺失变量会使 Plugin 加载失败。HTTP 映射到 client 的 Streamable HTTP transport，stdio 使用已准备 package 目录作为 `cwd`。只有现有 client 负责连接尝试、失败日志、远端工具同步、工具调用和断开。因此 MCP 连接失败会继续沿用“Plugin 成功但不注册工具”的既有行为，不会被重新分类为 repository 准备或 Loader 失败。
+
+未知 MCP 字段会被拒绝。这里有意排除 OAuth、`auth` 对象、`CLAUDE_PLUGIN_ROOT` 和更广泛的 Claude 兼容契约。Hooks、commands、agents、apps、任意 Cordis 代码、marketplace 和发现同样不受支持。Repository 子目录选择与 GitHub 配置属于后续 app/cache 集成，而不是本格式 package。
+
+## 考虑过的替代方案
+
+**加载仓库自己的 Cordis 入口。** 拒绝，因为这会把宣传为静态的格式变成无限制代码加载 API，要求仓库作者依赖 Harness 内部实现，并重复普通 SDK／Plugin dependency 路径。
+
+**让生成包装模块直接实现 skills 和 MCP。** 拒绝，因为复制的运行时代码会与 `dsh-skill-local` 和 `dsh-mcp-client` 漂移，尤其是提供方失效、工具同步、失败和 teardown 契约。
+
+**让每个生成包装模块 import Harness package。** 拒绝，因为 repository package 不应解析或锁定应用的内部依赖图。Loader builtin 提供一份由 app 所有的实现，并让生成包装模块保持无 import。
+
+**监视已准备 repository 资源。** 拒绝，因为一个精确 repository cache generation 是不可变的。Ref、子目录或配置变化会选择新 generation；第二套 watcher 会创造一套没有所有者的刷新身份。
+
+**把 MCP 连接失败当作 Loader 更新失败。** 拒绝，因为现有 MCP client 有意收束连接失败并不暴露工具。只对 repository source 改变该语义，会让同一 server 配置拥有两套失败契约。
+
+## 后果
+
+- 现有 skill／MCP 仓库可以新增一个很小的 `.dsh-plugin/package.json`，无需移动资源或采用 SDK 项目。
+- 已准备输出是确定性的静态胶水；已配置仓库及其依赖生命周期仍是受信任的可执行 package-manager 输入，而非 sandbox。
+- 多个 repository Plugin 通过提供方名称和普通 MCP server-name 唯一性共存；重复名称经现有 registry 失败，并参与 Loader 回滚。
+- Cache 内的源码编辑不会实时出现；必须选择另一个精确 source／ref／path／config。
+- 新增贡献类型必须提供显式格式和 DSH 自有运行时消费方；它不能意外以 repository JavaScript 形式进入。
+
+## 测试
+
+聚焦测试会准备 skills 与 MCP metadata，证明生成包装模块不含 import，拒绝 Work IQ 风格的 OAuth 字段，映射 Expo 风格 HTTP 与 DataJunction 风格 stdio 及环境变量，并覆盖缺失变量。真实 Loader 测试通过已注册 builtin 挂载生成包装模块，经 `ctx.skills` 读取其 skill，移除 Loader 条目并观察提供方清理。Keyless headless 示例通过真实 `cordis.yml` 加载一份签入的已准备包装模块，并快照 repository skill 写入日志的模型目录行。

+# @deepseek-ai/dsh-repository-plugin
+
+English | [中文](README.zh.md)
+
+Restricted repository Plugin format for DeepSeek Harness. A repository author declares static skill roots and an optional common `.mcp.json` in `.dsh-plugin/package.json`; the prepare helper copies those assets and emits a fixed import-free Cordis wrapper. The runtime wrapper can only delegate to this DSH-owned package, which composes [`dsh-skill-local`](../../skill/skill-local/README.md) and [`dsh-mcp-client`](../../mcp/mcp-client/README.md). Design rationale: [static repository Plugin format Agent Note](../../../.agents/notes/implemented/architecture/2026-07-30-static-repository-plugin-format.md).
+
+## Authoring format
+
+Place an ordinary package in the repository's `.dsh-plugin` directory:
+
+```json
+{
+  "name": "humanize-dsh-plugin",
+  "version": "0.0.0",
+  "private": true,
+  "scripts": {
+    "prepare": "dsh-plugin-prepare"
+  },
+  "devDependencies": {
+    "@deepseek-ai/dsh-repository-plugin": "^0.0.1"
+  },
+  "dsh": {
+    "skills": ["../skills"],
+    "mcpServers": "../.mcp.json"
+  }
+}
+```
+
+`dsh.skills` is an optional array of local skill roots. `dsh.mcpServers` is an optional path to one `.mcp.json`; at least one field is required. Paths are relative to `.dsh-plugin`, must stay under its parent source directory, and may therefore refer to existing repository assets such as `../skills`. A repository containing several Plugins gives each one its own `.dsh-plugin` package under a different selectable subdirectory.
+
+## Preparation
+
+`dsh-plugin-prepare` validates `package.json#dsh`, verifies skill-root types, parses the MCP file, copies assets under `dsh-plugin-assets`, and writes `dsh-plugin.mjs`. The wrapper contains only the normalized static manifest and fixed code that looks up the `dsh-repository-plugin` Loader builtin. It neither discovers nor compiles repository JavaScript, and the runtime never imports another repository entry point.
+
+The containing package manager still runs the configured repository package's lifecycle scripts. This restriction defines the supported DSH contribution surface; it is not a security boundary for a repository that the user chose to install as executable package-manager source.
+
+## Runtime composition
+
+Loading this package registers one effect-scoped Loader builtin. Each generated wrapper delegates to that builtin with its own module URL and prepared manifest. Repository skill roots mount as a uniquely named `dsh-skill-local` provider with default project/user roots excluded and watching disabled; cached package generations are immutable. Wrapper disposal removes the provider and all composed MCP clients through normal Cordis child-fiber teardown.
+
+## Common MCP format
+
+The `.mcp.json` root is `{ "mcpServers": { ... } }`. A stdio entry accepts only `type: "stdio"` (optional), `command`, `args`, and `env`; an HTTP entry accepts only `type: "http"`, `url`, and `headers`. String values support exact `${NAME}` process-environment expansion at Plugin load, and a missing name fails that load. HTTP URLs become the existing MCP client's `streamable-http` transport; stdio entries use the prepared package directory as `cwd`.
+
+Unknown fields reject, including OAuth and `auth` objects. There is no `CLAUDE_PLUGIN_ROOT` expansion or compatibility layer. After translation, the existing `dsh-mcp-client` exclusively owns transport creation, connection diagnostics, tool synchronization, calls, and disconnect lifecycle; a network or child-process connection failure retains that client's established log-and-no-tools behavior.
+
+## Export shape
+
+Namespace Plugin: named exports `name` / `inject` / `apply`, preparation constants, and `prepareDshPlugin`; no default export. The package also exposes the `dsh-plugin-prepare` executable and an invariant companion.
+
+## Model Experience
+
+### Repository skills
+
+#### What the model sees
+
+Indirectly through `dsh-tool-skill`: prepared, model-invocable skills join its logged catalog and selected instruction-body surface under their declared names and descriptions. The exact consumer schema is in the generated [`skill` tool catalog](../../../docs/tool-catalog.md#deepseek-aidsh-tool-skill).
+
+#### Token effect
+
+Conditional and data-dependent: each visible repository skill adds one capped catalog row; loading one adds its full current instruction body and resource-base guidance to retained tool history.
+
+#### KV Cache effect
+
+A stable prepared Plugin set is prefix-stable. Adding, removing, or replacing a repository Plugin can append the consumer's replacement catalog and affect later request prefixes.
+
+### Repository MCP tools
+
+#### What the model sees
+
+Indirectly through `dsh-mcp-client`: every connected server contributes its server-qualified tool schemas, and calls retain that client's canonical MCP results and rendering.
+
+#### Token effect
+
+Conditional on successful connection and the remote tool list; schemas recur on requests in the active tool view, while calls and results remain in history until compaction.
+
+#### KV Cache effect
+
+Stable connected tool lists are prefix-stable. Plugin lifecycle or MCP tool-list changes can change later tool-schema prefixes from the first affected definition.
+
+## Known Limitations and Deferred Work
+
+- **Skills and MCP only** — commands, hooks, agents, apps, arbitrary Cordis code, marketplaces, and compatibility shims are intentionally outside this format.
+- **No MCP authentication protocol** — static headers may use environment expansion, but OAuth-bearing definitions reject and private-server login flows are not implemented here.
+- **Generated assets are immutable runtime input** — repository cache generations are not watched; source, ref, path, or configuration must select another prepared generation.

+# @deepseek-ai/dsh-repository-plugin
+
+[English](README.md) | 中文
+
+这是 DeepSeek Harness 的受限 repository Plugin 格式。仓库作者在 `.dsh-plugin/package.json` 中声明静态 skill 根和可选的通用 `.mcp.json`；prepare helper 会复制这些资源并生成固定、无 import 的 Cordis 包装模块。运行时包装模块只能委托给这个由 DSH 自有的包，再由它组合 [`dsh-skill-local`](../../skill/skill-local/README.md) 与 [`dsh-mcp-client`](../../mcp/mcp-client/README.md)。设计依据见[静态 repository Plugin 格式 Agent Note（agent 决策记录）](../../../.agents/notes/implemented/architecture/2026-07-30-static-repository-plugin-format.md)。
+
+## 创作格式
+
+在仓库的 `.dsh-plugin` 目录中放置一个普通 package：
+
+```json
+{
+  "name": "humanize-dsh-plugin",
+  "version": "0.0.0",
+  "private": true,
+  "scripts": {
+    "prepare": "dsh-plugin-prepare"
+  },
+  "devDependencies": {
+    "@deepseek-ai/dsh-repository-plugin": "^0.0.1"
+  },
+  "dsh": {
+    "skills": ["../skills"],
+    "mcpServers": "../.mcp.json"
+  }
+}
+```
+
+`dsh.skills` 是可选的本地 skill 根数组。`dsh.mcpServers` 是指向一个 `.mcp.json` 的可选路径；两者至少声明一个。路径相对于 `.dsh-plugin`，必须留在其父级源码目录下，因此可以引用 `../skills` 等仓库现有资源。一个仓库可以在不同的可选择子目录下放置多个各自独立的 `.dsh-plugin` package。
+
+## 准备阶段
+
+`dsh-plugin-prepare` 校验 `package.json#dsh`、确认 skill 根类型、解析 MCP 文件、把资源复制到 `dsh-plugin-assets`，并写入 `dsh-plugin.mjs`。包装模块只包含规范化后的静态 manifest（元数据清单），以及查找 `dsh-repository-plugin` Loader builtin 的固定代码；它不会发现或编译仓库 JavaScript，运行时也不会导入仓库的其他入口。
+
+外层 package manager 仍会运行已配置仓库 package 的生命周期脚本。这里的限制只定义 DSH 所支持的贡献表面；对于用户选择以可执行 package-manager source 安装的仓库，它并不是安全边界。
+
+## 运行时组合
+
+加载本包会注册一个 effect-scoped Loader builtin。每个生成的包装模块都把自身模块 URL 和已准备的 manifest 委托给该 builtin。Repository skill 根以唯一命名的 `dsh-skill-local` 提供方挂载，排除默认项目／用户根并禁用监视；缓存 package generation 是不可变的。包装模块 dispose 时，会通过正常的 Cordis 子 fiber teardown 移除提供方和所有组合的 MCP client。
+
+## 通用 MCP 格式
+
+`.mcp.json` 根对象是 `{ "mcpServers": { ... } }`。stdio 条目只接受可选的 `type: "stdio"`、`command`、`args` 和 `env`；HTTP 条目只接受 `type: "http"`、`url` 和 `headers`。字符串值在 Plugin 加载时支持严格的 `${NAME}` 进程环境变量展开；缺失变量会使该次加载失败。HTTP URL 映射到现有 MCP client 的 `streamable-http` transport；stdio 条目以已准备的 package 目录作为 `cwd`。
+
+未知字段会被拒绝，包括 OAuth 字段与 `auth` 对象。不提供 `CLAUDE_PLUGIN_ROOT` 展开或兼容层。完成格式转换后，现有 `dsh-mcp-client` 独占 transport 创建、连接诊断、工具同步、调用和断开生命周期；网络或子进程连接失败沿用该 client 既有的“记录错误且不注册工具”行为。
+
+## 导出形状
+
+Namespace Plugin：具名导出 `name`／`inject`／`apply`、准备阶段常量和 `prepareDshPlugin`，不提供 default export。本包还提供 `dsh-plugin-prepare` 可执行文件和 invariant companion。
+
+## 模型体验
+
+### Repository skills
+
+#### 模型看到什么
+
+通过 `dsh-tool-skill` 间接呈现：已准备且允许模型调用的 skill 会按其声明的名称和描述进入该消费方记录到日志的目录及所选指令正文表面。消费方的确切 schema 见生成的 [`skill` 工具目录](../../../docs/tool-catalog.md#deepseek-aidsh-tool-skill)。
+
+#### Token 影响
+
+有条件且随数据变化：每个可见的 repository skill 增加一行受限长度的目录项；加载一个 skill 会把其当前完整指令正文和资源基准指引加入保留的工具历史。
+
+#### KV Cache 影响
+
+稳定的已准备 Plugin 集合保持前缀稳定。添加、移除或替换 repository Plugin 可能使消费方追加替换目录，并影响后续请求前缀。
+
+### Repository MCP 工具
+
+#### 模型看到什么
+
+通过 `dsh-mcp-client` 间接呈现：每个已连接 server 都贡献带 server 限定名的工具 schema；调用会保留该 client 的规范 MCP 结果和渲染。
+
+#### Token 影响
+
+取决于连接成功和远端工具列表；schema 会在对应工具视图中的请求上重复出现，而调用与结果会留在历史中直至压缩。
+
+#### KV Cache 影响
+
+稳定的已连接工具列表保持前缀稳定。Plugin 生命周期或 MCP 工具列表变化可能从首个受影响定义开始改变后续工具 schema 前缀。
+
+## 已知限制与延后工作
+
+- **仅支持 skills 与 MCP**：commands、hooks、agents、apps、任意 Cordis 代码、marketplace 和兼容 shim 均有意排除在该格式之外。
+- **没有 MCP 认证协议**：静态 header 可以使用环境变量展开，但带 OAuth 的定义会被拒绝，私有 server 登录流程不在此实现。
+- **生成资源是不可变运行时输入**：repository cache generation 不受监视；必须改变 source、ref、path 或配置才能选择另一份已准备 generation。

+The project root is the nearest ancestor containing `.git`; without one, the current cwd is used. The user DSH root skips its `.system` child so system-owned directories are not treated as normal user skills. `includeDefaultRoots: false` omits both project and user rows while retaining explicitly configured custom and bundled roots, allowing several uniquely named isolated providers such as immutable repository Plugins. This provider supplies project and user skills; another provider may supply built-in system skills.
 
 When `ctx.fs` is available, discovery lists roots through `ctx.fs.listDir`, reads skill files through `ctx.fs.readText`, and probes `.git` through the filesystem service. Full skill loads forward the lookup abort signal to filesystem metadata and content reads. Without a filesystem service, the provider falls back to abortable Node filesystem I/O so minimal local contexts can still load skills. Confirmed missing paths are valid empty state, malformed or non-text entries warn and skip, and unexpected discovery/read failures make the registry snapshot incomplete rather than replacing a last-good model catalog with a misleading deletion.

Subject: [PATCH 328/557] fix(review): validate skill roots at mount and
 isolate provider default roots

ds-review-bot round 1 on the repository-plugin runtime:
- a manifest-declared skill root absent or non-directory in the installed
  package now fails the plugin load (skill-local treats a missing root as
  legitimately empty, which silently mounted a skill-less plugin)
- includeDefaultRoots: false no longer inherits $DSH_BUNDLED_SKILL_DIR, so
  isolated repository providers see only their explicit roots
- prepared wrapper baseUrl schema requires the file: scheme, failing hostile
  URLs at the declared validation boundary
- preparedPath reuses format.ts's isOutside; SERVER_NAME_PATTERN is exported
  and pinned equal to dsh-mcp-client's, with the restatement justified (the
  prepare bin keeps a zod-only module graph); the unexplained `as never`
  cast now carries its schemastery rationale
- the import-free wrapper assertion also rejects dynamic import(
- the headless fixture wrapper is regenerated by the real prepareDshPlugin
  and a drift test pins fixture == generator output
- prepareDshPlugin JSDoc states the non-atomic publish repair contract

 `@deepseek-ai/dsh-repository-plugin` owns a restricted `.dsh-plugin` package format with two contribution kinds only: skill roots and one common `.mcp.json`. Its package metadata uses `package.json#dsh.skills` for relative skill-root paths and `package.json#dsh.mcpServers` for the relative MCP document path. At least one is required. Each path may leave `.dsh-plugin` to reuse repository content but must remain beneath the directory containing that `.dsh-plugin`; a nested selectable Plugin therefore owns the adjacent subtree above its package without gaining access to unrelated host paths.
 
-The `.dsh-plugin` package declares `dsh-plugin-prepare` as its ordinary package-manager `prepare` script. The helper validates metadata and source types, strictly parses `.mcp.json`, copies static assets into `dsh-plugin-assets`, and writes `dsh-plugin.mjs`. The `.mjs` extension avoids imposing `type: module` on repository-authored package metadata. The generated module is a fixed import-free template containing only a normalized manifest, `inject = ['loader']`, and delegation to the `dsh-repository-plugin` Loader builtin. Preparation never discovers, transpiles, bundles, or preserves a custom repository entry point.

Preparation never discovers, transpiles, bundles, or preserves a custom repository entry point.
 
 Loading the DSH package registers that builtin as an effect. A generated wrapper mounts the builtin as its child with `import.meta.url`, so all contributions belong to the wrapper fiber and disappear on Loader removal or rollback. The builtin revalidates the prepared manifest and path containment before reading assets. It composes the existing implementations rather than registering skills or MCP tools itself.

This provider supplies project and user skills; another provider may supply built-in system skills.
 
 When `ctx.fs` is available, discovery lists roots through `ctx.fs.listDir`, reads skill files through `ctx.fs.readText`, and probes `.git` through the filesystem service. Full skill loads forward the lookup abort signal to filesystem metadata and content reads. Without a filesystem service, the provider falls back to abortable Node filesystem I/O so minimal local contexts can still load skills. Confirmed missing paths are valid empty state, malformed or non-text entries warn and skip, and unexpected discovery/read failures make the registry snapshot incomplete rather than replacing a last-good model catalog with a misleading deletion.

+The TUI and Web register the exact personal path through Cordis HMR after boot.

+- `dsh` from any directory (and `pnpm run demo:tui`) can apply personal providers, models, repository Plugins, and other Loader entries with no checkout edit; verified end-to-end against a personal Anthropic proxy with Opus 4.8, including a bash tool round trip.
 - Because an id-targeted patch replaces the whole `config`, a personal override restates the base fields it keeps and can drift when the base entry changes shape; the loader's entry-not-found/name-mismatch warnings and [`dsh --dump-config`](2026-07-30-dsh-dump-config.md) (which prints the composed tree those patches produce) are the diagnostics.
 - Personal patches resolve ids against the booted file's own tree, so nested-include overlays (Code Mode) are not personalized; live-run parity for those leaves is deferred.
 - `dsh-app-boot` depends on `js-yaml` and imports the include's `!!js` YAML dialect (`entryListSchema`) directly, and, like `apps/cli`, depends on `@deepseek-ai/dsh-paths` for `resolveDshHome`.
-- When PR #443 lands, `apps/cli/src/bin.ts`'s dispatch chain and `apps/cli/package.json`'s dependency list conflict textually; both resolve as unions (their `web`/`-p` branches plus our default-TUI branch).

+# Agent Note: Config-only repository Plugins for standalone dsh
+
+Status: implemented
+
+English | [中文](2026-07-30-config-only-repository-plugins.zh.md)
+
+## Problem
+
+A standalone `dsh` user has no developer-owned SDK project whose `package.json`, lockfile, and `cordis.yml` can carry an external Plugin dependency. Requiring an install command or another state file would make “use this repository” a multi-step workflow, while loading arbitrary repository code would bypass the restricted [static repository Plugin format](../architecture/2026-07-30-static-repository-plugin-format.md). Long-running TUI and Web processes also need a failed edit to preserve their usable Plugin generation and tell observers why the candidate was rejected.
+
+## Decision
+
+The shipped TUI and Web/headless `cordis.yml` trees contain an empty `repository-plugins` entry. A user changes only `$DSH_HOME/config.yaml`, replacing that entry's config with a `repositories` list. Each item uses `github:owner/repository#` plus an optional `&path:/.../.dsh-plugin`; omission selects `/.dsh-plugin`. An explicit ref is mandatory, paths are absolute within the repository and end in `.dsh-plugin`, and duplicate normalized specifiers reject before installation. There is no marketplace, discovery index, HTTPS URL vocabulary, or implicit latest generation.
+
+`@deepseek-ai/dsh-repository-plugin` validates and normalizes each source, then resolves it through the generic vendored [`RepositoryCache`](../architecture/2026-07-30-package-manager-native-repository-cache.md). The default cache is `$DSH_HOME/cache/repository-plugins`; `cacheDir` is the explicit deployment override. Bundled pnpm selects the configured repository subpackage, runs its ordinary lifecycle including `prepare`, and atomically publishes the exact specifier. The DSH host imports only the generated `dsh-plugin.mjs` wrapper and mounts it as a child fiber, so skills and MCP retain the owners, failure contracts, and teardown defined by the format package.
+
+## Live update and failure
+
+`dsh-app-boot` mounts the root Include through one helper that retains its exact Loader `Entry`. The TUI and Web register `$DSH_HOME/config.yaml` through Cordis HMR; headless reads the same file at startup without retaining a watcher. A watcher update rebuilds the Include patch list as immutable app-owned patches followed by the newly parsed personal patches, so Web-generated port, session-root, trust, and frontend values survive every personal edit unless a later personal patch deliberately replaces that row.
+
+Cordis serializes and coalesces exact-path changes. Include and Loader reconcile a candidate transactionally: success commits the new source list, while fetch, preparation, wrapper import, format, or child-Plugin failure rejects the candidate and retains or restores the last good tree. HMR normalizes the caught value to `Error`, logs it, and broadcasts the parallel `hmr/config-update-failed(filename, error)` event; observer failures cannot break refresh processing. MCP transport connection failure remains the existing MCP client's contained successful-Plugin/no-tools result and therefore is not reclassified as a config-update failure.
+
+An identical specifier permanently reuses its cache generation. HMR watches configuration, not cached repository code; the user changes the ref, path, or source list to select another generation.
+
+## Trust boundary
+
+Configuring a repository authorizes package-manager lifecycle code from that repository and its dependencies to run with the user's filesystem authority. The pnpm child removes ambient environment variables whose names contain `KEY`, `PASSWORD`, `SECRET`, or `TOKEN`, but this is credential-exposure reduction rather than a sandbox. The fixed runtime wrapper prevents repository-authored Cordis entry points from becoming part of the supported Plugin format; it does not make package preparation untrusted-safe.
+
+## Alternatives considered
+
+**Require an SDK project dependency.** Rejected for the standalone app path because there is no project manifest to edit. Developer-owned SDK projects keep their native package-manager workflow as a separate capability.
+
+**Add a `dsh plugin install` command and installation database.** Rejected because the personal Loader overlay already owns machine-local composition. A second mutation interface and durable registry would duplicate config identity and rollback.
+
+**Resolve repositories directly in the DSH package.** Rejected because Git transport, GitHub subpackage selection, lifecycle execution, and content storage belong to pnpm and the generic Loader cache, not a DSH-specific adapter.
+
+**Watch cache contents or refresh the same ref automatically.** Rejected because one config value must identify one immutable prepared generation. Background remote resolution would change executable code without a config diff and make rollback depend on mutable remote state.
+
+**Broadcast an `unknown` failure payload.** Rejected at the HMR boundary. JavaScript may throw any value internally, but the public event always receives a normalized `Error`, giving observers one stable contract while retaining the original value as its cause when needed.
+
+## Consequences
+
+- A repository that adds `.dsh-plugin/package.json` can reach standalone users through one personal-config edit without changing its existing skills or `.mcp.json` layout.
+- Long-running apps can add, replace, or remove configured generations without restart; rejected candidates retain the last good runtime and produce one generic Cordis event.
+- First use may require Git/network access and preparation time. Later starts reuse the exact prepared cache; old generations consume disk until a separate cache-management policy exists.
+- Only skills and common MCP definitions are supported. Hooks, commands, agents, apps, arbitrary Cordis code, compatibility shims, OAuth-bearing MCP definitions, and marketplaces remain intentionally absent.
+
+## Testing
+
+Repository-package tests pin source normalization, default and nested `.dsh-plugin` paths, cache-root resolution, duplicate rejection, prepared-wrapper loading, and disposal. App-boot tests drive exact-path add, two failure classes, recovery, removal, failure events, and generated-patch preservation through the real HMR/Include/Loader path. A keyless PTY smoke boots the shipped `dsh` composition from personal config alone and invokes a skill from a seeded immutable cache generation.

+独立 `dsh` 用户没有开发者自有的 SDK 项目，无法由其 `package.json`、lockfile 和 `cordis.yml` 承载外部插件依赖。若要求运行安装命令或维护另一份状态文件，「使用这个仓库」就会变成多步骤流程；若加载任意仓库代码，又会绕过受限的[静态仓库插件格式](../architecture/2026-07-30-static-repository-plugin-format.md)。长时间运行的 TUI 和 Web 进程还必须在编辑失败时保留仍可使用的插件版本，并向观察者说明候选配置被拒绝的原因。
+
+## 决策
+
+已交付的 TUI 和 Web／无头 `cordis.yml` 配置树包含一个空的 `repository-plugins` 配置项。用户只需修改 `$DSH_HOME/config.yaml`，用 `repositories` 列表替换该配置项的配置。每一项采用 `github:owner/repository#`，并可追加 `&path:/.../.dsh-plugin`；省略时选择 `/.dsh-plugin`。必须显式指定 ref；路径是仓库内的绝对路径，并以 `.dsh-plugin` 结尾；重复的规范化说明符在安装前即被拒绝。不提供插件市场、发现索引、HTTPS URL 词汇或隐式的最新版本。
+
+`@deepseek-ai/dsh-repository-plugin` 校验并规范化每个源，再通过 vendor 中的通用 [`RepositoryCache`](../architecture/2026-07-30-package-manager-native-repository-cache.md) 解析。默认缓存位于 `$DSH_HOME/cache/repository-plugins`；`cacheDir` 是显式的部署覆盖项。随应用提供的 pnpm 选择配置的仓库子包（package），运行包括 `prepare` 在内的普通生命周期，并原子发布该精确说明符。DSH 宿主只导入生成的 `dsh-plugin.mjs` 包装模块并将其挂载为子 fiber，因此 skill（技能）与 MCP 仍沿用格式包定义的所有者、失败契约和清理行为。
+
+## 实时更新与失败
+
+`dsh-app-boot` 通过一个辅助函数挂载根 Include，并保留其确切的 Loader `Entry`。TUI 和 Web 通过 Cordis HMR（热模块替换）注册 `$DSH_HOME/config.yaml`；无头界面在启动时读取同一文件，但不保留监视器。监视器更新会重新构建 Include 补丁列表，先放置不可变的应用自有补丁，再放置新解析的个人补丁。因此，Web 生成的端口、会话根目录、信任和前端值会在每次个人编辑后保留，除非后续个人补丁有意替换相应配置项。
+
+Cordis 会串行处理并合并该确切路径上的变更。Include 与 Loader 以事务方式协调候选配置：成功时提交新源列表；拉取、准备、包装模块导入、格式或子插件失败时拒绝候选配置，并保留或恢复最后一个可用树。HMR 会把捕获的值规范化为 `Error`，记录错误，并广播并行的 `hmr/config-update-failed(filename, error)` 事件；观察者失败不会中断刷新处理。MCP 传输连接失败仍沿用现有 MCP 客户端所收束的「插件成功加载但无工具」结果，因此不会被重新分类为配置更新失败。
+
+相同说明符会永久复用同一个缓存版本。HMR 监视配置，而非已缓存的仓库代码；用户必须改变 ref、路径或源列表，才能选择另一个版本。
+
+## 信任边界
+
+配置仓库即授权该仓库及其依赖中的包管理器生命周期代码以用户的文件系统权限运行。pnpm 子进程会移除名称中含有 `KEY`、`PASSWORD`、`SECRET` 或 `TOKEN` 的环境变量，但这只会减少凭据暴露，并非沙箱。固定的运行时包装模块会阻止仓库作者提供的 Cordis 入口成为受支持插件格式的一部分；它无法让包准备过程安全执行不受信任的代码。
+
+## 考虑过的替代方案
+
+**要求声明 SDK 项目依赖。** 独立应用路径没有可编辑的项目 manifest（元数据清单），因此否决。开发者自有的 SDK 项目仍可使用原生包管理器工作流，这是一项独立能力。
+
+**新增 `dsh plugin install` 命令和安装数据库。** 否决，因为个人 Loader 覆盖层已经负责机器本地组合。第二个变更接口和持久注册表会重复配置身份与回滚机制。
+
+**由 DSH 包直接解析仓库。** 否决，因为 Git 传输、GitHub 子包选择、生命周期执行和内容存储属于 pnpm 与通用 Loader 缓存，而非 DSH 专用适配器。
+
+**监视缓存内容，或自动刷新相同 ref。** 否决，因为一个配置值必须标识一个不可变的已准备版本。后台远端解析会在没有配置差异的情况下改变可执行代码，并使回滚依赖可变的远端状态。
+
+**广播 `unknown` 失败载荷。** 在 HMR 边界否决。JavaScript 内部可以抛出任意值，但公开事件始终接收规范化的 `Error`，从而为观察者提供稳定契约，并在需要时把原始值保留为错误原因。
+
+## 后果
+
+- 添加 `.dsh-plugin/package.json` 的仓库只需一次个人配置编辑即可供独立用户使用，无需改变现有 skill 或 `.mcp.json` 布局。
+- 长时间运行的应用无需重启即可新增、替换或移除已配置版本；被拒绝的候选配置会保留最后一个可用运行时，并产生一个通用 Cordis 事件。
+- 首次使用可能需要 Git／网络访问和准备时间。后续启动会复用这份精确的已准备缓存；在另行制定缓存管理政策之前，旧版本会持续占用磁盘空间。
+- 仅支持 skill 和通用 MCP 定义。钩子、命令、agent（智能体）、应用、任意 Cordis 代码、兼容 shim、带 OAuth 的 MCP 定义和插件市场均有意不提供。
+
+## 测试
+
+仓库包测试固定源规范化、默认和嵌套 `.dsh-plugin` 路径、缓存根解析、重复项拒绝、已准备包装模块加载及资源释放。App-boot 测试通过真实 HMR／Include／Loader 路径驱动确切路径的新增、两类失败、恢复、移除、失败事件及生成补丁保留。一个无密钥 PTY 冒烟测试仅通过个人配置启动已交付的 `dsh` 组合，并从预置的不可变缓存版本中调用一个 skill。

 - resumes a persisted session with `dsh --resume ` and, when the Node host exposes `process.execve`, supplies the TUI's in-place handoff host: after selector preflight and current-session flush, the host disposes the app and replaces the process with a normalized resume invocation; runtimes without process replacement leave the session running and say so. This CLI owns session identity and the exit line rather than the config: it mints or selects the `main` session id and provides it, plus the exact command that reproduces this invocation, on the boot context ([`MAIN_SESSION_ID_KEY`](../../packages/ui/tui/README.md) and `TUI_GOODBYE_MESSAGE_KEY`). No `cordis.yml` key can drop resume, and a missing or unreadable id fails loud instead of creating a fresh session;
 - treats the **invoking directory** as the workspace — sessions, relative paths, and workspace instructions resolve from the cwd (`dsh meta` is the sole exception, below);
 - tells the agent where its own source lives: after boot it adds a prompt section naming this harness checkout, resolved from the launcher's real path so it holds under a PATH symlink and an arbitrary cwd, so the self-referential `cordis` toolset can read and modify it;

Environment precedence is ambient > project `.env`. The shipped tree's Cordis HMR keeps `config.yaml` live; an explicit `--config` tree replaces that overlay, and a tree without HMR reads it at startup only.

The official DeepSeek icon, responsive terminal rasters, all-locale Chinese copy, and notice version are static local owners; the overlay never writes a session event or model context.
 - registers bare `/compact`: while the agent is idle, it summarizes useful older history even below automatic pressure, rejects arguments, and reports success only after the standalone replacement bracket is durable. A prompt submitted during compaction keeps its queue identity and starts after that checkpoint; injected context remains visible.

 The shared composition defaults new TUI, Web, and headless sessions to the `workspace-write` permission preset (`workspace-write` file mode plus `ask` approval policy). Sandbox-enforced bash and filesystem mutations may write only under the session workspace and platform temporary roots; reads, network access, and process visibility are not confined. The browser answers one-shot approval requests and exposes the Access picker; the TUI exposes `/permission`, but has no approval-request answerer, so an automatic wider retry there fails closed until the user deliberately changes the session preset. `DSH_PERMISSION_MODE` changes the process fallback, while a stored General-settings Permission value applies to later sessions without changing an open one.
 
+All three surfaces consume `$DSH_HOME/config.yaml`; the TUI and Web apply valid edits live, while one-shot headless runs read it at startup. The shipped trees include an empty `repository-plugins` row, so a standalone user can add prepared GitHub Plugins without an SDK project or install command:
+
+```yaml
+- id: repository-plugins
+  name: '@deepseek-ai/dsh-repository-plugin'
+  config:
+    repositories:
+      - 'github:PolyArch/humanize#'
+```
+
+The repository must contain a prepared `.dsh-plugin` package; the [repository Plugin contract](../../packages/cordis/repository-plugin/README.md#standalone-app-configuration) documents authoring, nested Plugin paths, the immutable cache, trust boundary, and failure semantics. A failed live edit keeps the last good tree and emits Cordis's `hmr/config-update-failed` event.
+
 The shipped TUI and Web compositions register the native DeepSeek adapter plus pi-ai OpenAI and Anthropic profiles. Credentials and endpoint overrides come from the provider-standard `DEEPSEEK_API_KEY` / `DEEPSEEK_BASE_URL`, `OPENAI_API_KEY` / `OPENAI_BASE_URL`, and `ANTHROPIC_API_KEY` / `ANTHROPIC_BASE_URL` pairs in the boot's layered environment.
 
 Every surface also registers `web_search` and only `web_search`. Search uses DeepSeek's Anthropic-compatible Messages endpoint, resolves the same `DEEPSEEK_API_KEY` reference for every call, and accepts the separate `DEEPSEEK_SEARCH_BASE_URL` endpoint override; each search is an auxiliary model request with its own latency and token cost. `web_fetch` remains disabled and the composition mounts no default fetch provider, so deployments that need arbitrary page retrieval must opt in through an overlay. The deployment decision and its security boundary live in the [default Web search Agent Note](../../.agents/notes/implemented/feature/2026-07-31-web-default-search.md).

@@ -28,6 +28,23 @@ Place an ordinary package in the repository's `.dsh-plugin` directory:
 
 `dsh.skills` is an optional array of local skill roots. `dsh.mcpServers` is an optional path to one `.mcp.json`; at least one field is required. Paths are relative to `.dsh-plugin`, must stay under its parent source directory, and may therefore refer to existing repository assets such as `../skills`. A repository containing several Plugins gives each one its own `.dsh-plugin` package under a different selectable subdirectory.
 
+## Standalone app configuration
+
+The shipped `dsh` TUI, Web, and headless trees contain an empty `repository-plugins` row. A standalone user enables exact GitHub generations by replacing that row's config in `$DSH_HOME/config.yaml` (default `~/.dsh/config.yaml`):
+
+```yaml
+- id: repository-plugins
+  name: '@deepseek-ai/dsh-repository-plugin'
+  config:
+    repositories:
+      - 'github:PolyArch/humanize#'
+      - 'github:owner/repository#&path:/plugins/one/.dsh-plugin'
+```
+
+Each source must use `github:owner/repository#`. Omitting `&path:` selects `/.dsh-plugin`; an explicit path is absolute within the repository and must end in `.dsh-plugin`. A commit ref gives the clearest immutable identity, while tags and branches remain accepted exact config values. `cacheDir` may override the default `$DSH_HOME/cache/repository-plugins` cache root.
+
+The TUI and Web watch `config.yaml` through Cordis HMR. A valid source-list change installs and swaps the complete repository Plugin generation; a failed fetch, prepare, import, or Plugin application keeps the last good tree and broadcasts `hmr/config-update-failed(filename, error)`. Headless runs consume the file only at startup. An identical source string permanently reuses its prepared cache entry, so selecting changed code requires a ref, path, or other source-config change. App integration rationale: [config-only repository Plugins Agent Note](../../../.agents/notes/implemented/feature/2026-07-30-config-only-repository-plugins.md).
+
 ## Preparation
 
 `dsh-plugin-prepare` validates `package.json#dsh`, verifies skill-root types, parses the MCP file, copies assets under `dsh-plugin-assets`, and writes `dsh-plugin.mjs`. The wrapper contains only the normalized static manifest and fixed code that looks up the `dsh-repository-plugin` Loader builtin. It neither discovers nor compiles repository JavaScript, and the runtime never imports another repository entry point.

 `dsh.skills` 是可选的本地 skill 根数组。`dsh.mcpServers` 是指向一个 `.mcp.json` 的可选路径；两者至少声明一个。路径相对于 `.dsh-plugin`，必须留在其父级源码目录下，因此可以引用 `../skills` 等仓库现有资源。一个仓库可以在不同的可选择子目录下放置多个各自独立的 `.dsh-plugin` package。
 
+## 独立应用配置
+
+已交付的 `dsh` TUI、Web 和无头配置树包含一个空的 `repository-plugins` 配置项。独立用户只需在 `$DSH_HOME/config.yaml`（默认 `~/.dsh/config.yaml`）中替换该配置项的配置，即可启用精确指定的 GitHub generation：
+
+```yaml
+- id: repository-plugins
+  name: '@deepseek-ai/dsh-repository-plugin'
+  config:
+    repositories:
+      - 'github:PolyArch/humanize#'
+      - 'github:owner/repository#&path:/plugins/one/.dsh-plugin'
+```
+
+每个源都必须采用 `github:owner/repository#`。省略 `&path:` 时选择 `/.dsh-plugin`；显式路径是仓库内的绝对路径，并且必须以 `.dsh-plugin` 结尾。commit ref 提供最清晰的不可变身份；tag 和 branch 仍可作为显式配置值使用。`cacheDir` 可覆盖默认缓存根 `$DSH_HOME/cache/repository-plugins`。
+
+TUI 和 Web 通过 Cordis HMR（热模块替换）监视 `config.yaml`。有效的源列表变更会安装并替换整套仓库插件 generation；拉取、准备、导入或插件应用失败时，最后一个可用树保持运行，并广播 `hmr/config-update-failed(filename, error)`。无头运行只在启动时使用该文件。相同的源字符串会永久复用其已准备缓存条目，因此必须改变 ref、路径或其他源配置，才能选择发生变化的代码。应用集成依据见[仅凭配置接入仓库插件的 Agent Note](../../../.agents/notes/implemented/feature/2026-07-30-config-only-repository-plugins.md)。
+
 ## 准备阶段
 
 `dsh-plugin-prepare` 校验 `package.json#dsh`、确认 skill 根类型、解析 MCP 文件、把资源复制到 `dsh-plugin-assets`，并写入 `dsh-plugin.mjs`。包装模块只包含规范化后的静态 manifest（元数据清单），以及查找 `dsh-repository-plugin` Loader builtin 的固定代码；它不会发现或编译仓库 JavaScript，运行时也不会导入仓库的其他入口。

+A developer's machine-local preferences live outside every repository in the Harness home (default `~/.dsh`, overridable via `$DSH_HOME`; the single root [`resolveDshHome`](../../util/paths/README.md) resolves), consumed by the `dsh` CLI's TUI, Web, and headless surfaces ([`apps/cli`](../../../apps/cli/README.md)); the demo bins boot their committed trees verbatim. Two optional files:
 
 - **`.env`** — the credential store of [`dsh-credentials-local`](../../credentials/credentials-local/README.md), read by that provider alone. No surface hoists it into `process.env`: doing so would make every stored key look like a read-only launch override on the next run, blocking rotation from the TUI and the web page. The environment layers are the ambient one and the invoking directory's `.env` (loaded by the bin; `process.loadEnvFile` never overrides), and a composition without the credential provider keeps resolving keys from those alone.
 - **`config.yaml`** — loader overlay patches applied over the shipped default config, with the same semantics as the shipped surface overlays: an id-targeted patch replaces the named entry's whole `config` (restate unchanged fields), `insert` adds entries, and `!!js` expressions interpolate at mount. A patch naming an entry id absent from the booted tree is a silent no-op. An empty or comments-only file throws (it parses to nothing, not to a list); disable the overlay with `[]` or by deleting the file.
 
+The TUI and Web keep `config.yaml` live through `watchPersonalPatches`; one-shot headless runs read only the startup value. The watcher targets the exact personal path even when the file or immediate parent does not exist, serializes bursts, and recomposes the personal patches inside the caller's layer order (surface overlay below, app-generated patches above). A rejected read, parse, or Loader candidate leaves the last good tree running and the HMR service broadcasts `hmr/config-update-failed(filename, Error)` after logging it; observer failures are contained. Disposing the context closes the watcher and drains an active refresh.
+
 Subprocess test launchers point `DSH_HOME` at an isolated per-test directory so a developer's personal overlay can never leak into fixtures.

 - **`.env`**：[`dsh-credentials-local`](../../credentials/credentials-local/README.md) 的凭据存储，只由该 provider 读取。没有任何表层会把它提升进 `process.env`：那样做会让每个已存密钥在下次运行时看起来都像只读的启动时覆盖，从而阻断从 TUI 与 Web 页面轮换密钥。环境层次由环境中的值与调用目录的 `.env` 构成（由 bin 加载；`process.loadEnvFile` 从不覆盖已有值），没有凭据 provider 的组合仍然只从这两者解析密钥。
 - **`config.yaml`**：在发布的默认配置上应用 Loader overlay patch，语义与交付的 surface overlay 相同：按 id 定位的 patch 会替换对应条目的整个 `config`（未改字段也要重述），`insert` 会添加条目，`!!js` 表达式则在挂载时插值。如果 patch 指定的条目 id 不在已启动树中，则静默不执行任何操作。空文件或仅含注释的文件会抛出异常（其解析结果为空，而不是列表）；如需禁用 overlay，请使用 `[]` 或删除该文件。
 
+TUI 和 Web 会持续应用 `config.yaml` 的变更，具体由 `watchPersonalPatches` 负责；一次性无头运行只读取启动时的值。即使该文件或其直接父目录不存在，watcher 仍会监视确切的个人配置路径；它会串行处理突发变更，并按调用方的层次顺序重新组合个人 patch（surface overlay 在下、应用生成的 patch 在上）。读取失败、解析失败或 Loader 候选被拒时，最后一个可用树会继续运行；HMR 服务记录错误后广播 `hmr/config-update-failed(filename, Error)`，并隔离 observer 失败。上下文 dispose 时会关闭 watcher，并等待进行中的刷新结束。
+
 子进程测试 launcher 会把 `DSH_HOME` 指向逐测试隔离的目录，确保开发者的个人 overlay 不会泄漏到 fixture（测试前置数据）中。

Subject: [PATCH 330/557] fix(review): audit prepared-wrapper activation and
 pin generated shapes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ds-review-bot round 1 on the DSH-home integration:
- generated wrappers now inject the services their manifest needs (skills/
  tools beside loader), and loadPreparedRepository rejects a wrapper fiber
  that settles anything but ACTIVE — a composition missing a required
  service fails the repository transaction instead of committing an ACTIVE
  row over a silently PENDING child (critical finding)
- the github: source ref segment excludes '#', so 'a#b' refs fail at the
  config parser with the promised syntax instead of inside pnpm
- watchPersonalPatches re-reads the include's non-patch options per refresh
  instead of a registration-time snapshot
- the TUI smoke's cache-seeded wrapper is produced by the real
  prepareDshPlugin (cache LAYOUT stays a deliberate external pin)
- new Loader integration test drives a live repositories update through
  entry.update: generation swap, old skills removed, failed candidate
  rolled back to the previous generation

Subject: [PATCH 331/557] fix(review): tolerate mid-teardown personal-watcher
 registration

CI caught a startup race the PTY smoke stages naturally: a TUI /exit typed
while watchPersonalPatches is still opening its watcher disposes the tree,
and the HMR effect registration rejects with INACTIVE_EFFECT, crashing an
app that exited exactly as asked. Return a no-op disposer for that exact
code; every other registration failure still propagates (covered both ways).

Subject: [PATCH 332/557] fix(goal): emit bare GoalRef in fold lastRef and
 goal/changed notifications

goalChangeRef returned the full GoalSnapshot for every snapshot operation,
so foldGoal(...).lastRef and the goal/changed notification ref carried
objective, phase, and maxGoalRounds fields instead of the declared
GoalRef { id, revision }. Only the clear tombstone was bare. Emit an exact
{ id, revision } ref for snapshot changes and pin the contract with a
regression test covering create/edit/block notifications and the fold.

+# Agent Note: Native GitHub stacks and optional PR rebases
+
+Status: implemented
+
+English | [中文](2026-08-02-native-github-stacks-and-optional-rebases.zh.md)
+
+## Problem
+
+A dependent PR chain represented only by base branches has no official stack identity. Landing it requires manually merging one PR at a time, preserving intermediate branches, retargeting every child, and reconstructing whether the chain survived. GitHub's native stacked-PR feature instead carries the order, applies trunk rules and CI to every layer, and owns bottom-up merges and retargeting.
+
+A blanket prohibition on rewriting reviewed branches also excludes the native `gh stack` synchronization workflow, whose cascading rebase updates each active layer and publishes it with lease protection. Applying that prohibition only outside stacks would give standalone and stacked PRs inconsistent history choices.
+
+## Decision
+
+Every same-repository chain of two or more dependent PRs uses GitHub's official stack object before landing. Live `PullRequest.stack` and `stackEntry.position` fields are authoritative. An unstacked chain whose PRs have one author is linked automatically in bottom-to-top order with `gh stack link`; mixed or unavailable authors require user confirmation. Missing native support and cross-fork chains hard-stop. Existing membership in conflicting stacks or an official order that disagrees with the branch topology requires user direction before any stack is dissolved or rebuilt.
+
+"Land the stack" merges the complete official stack through `gh stack merge  --yes --merge`. A partial landing requires an explicit boundary PR and merges the bottom prefix through that PR. The workflow never falls back to per-PR `gh pr merge` and manual retargeting. A direct native merge is all-or-nothing; a merge queue may process the selected PRs in separate groups, so every selected PR must independently reach `MERGED` before the landing is complete.
+
+Merge-forward and rebase are both allowed refresh histories for standalone and officially stacked PRs, including after review. A remote history rewrite uses an exact lease or the lease-protected `gh stack` push path and aborts if the remote moved; raw `--force` is forbidden. The [incremental base-retargeting decision](2026-07-26-incremental-pr-base-retargeting.md) remains the owner of the merge-forward option.
+
+Relevant checks normally run before publication. `gh stack sync` is the explicit exception because it fetches, cascade-rebases, and pushes as one operation: every rewritten layer is validated immediately afterward, and no affected PR merges until that evidence passes. After any rewritten push, current heads, unresolved review threads, approvals, mergeability, and checks are re-audited because earlier commit OIDs and inline anchors may be outdated.
+
+## Verification
+
+The [stack landing skill](../../../skills/dsh-merging-stacked-prs/SKILL.md) verifies native support, same-repository branches, live authors, official membership and order, merge range, and final merged state. The [stack review guide](../../../../docs/cookbook/responding-to-pr-review-on-a-stack.md) keeps fixes on their introducing layer and covers both propagation histories. The [pre-push workflow](../../../skills/dsh-pre-push-checks/SKILL.md) owns lease protection and immediate post-sync evidence.
+
+## Alternatives considered
+
+**Keep branch chains as the only stack representation.** This preserves the manual procedure but gives GitHub no stack object through which to show order, enforce trunk rules across every layer, or merge a range atomically.
+
+**Adopt native stacks while forbidding their rebase commands after review.** This keeps commit OIDs stable but disables the official synchronization path when a stack is under active review and leaves standalone PRs under a different policy.
+
+**Require rebase for every PR refresh.** A linear history is useful, but merge checkpoints remain a valid choice when preserving completed conflict resolution and its recovery point matters more than compact history.
+
+**Automatically dissolve conflicting stacks.** This would make local branch inference override shared GitHub metadata and could disturb PRs or authors outside the requested chain; merged and queued entries cannot always be removed.
+
+## Consequences
+
+- Reviewers and automation receive GitHub's stack map, stack-wide rules, CI, and native merge state.
+- A same-author legacy chain becomes official without an extra prompt, while mixed ownership and conflicting metadata retain a human decision boundary.
+- Rebases can invalidate commit hashes, approvals, or comment anchors after review, so every rewritten push carries a live review and check audit.
+- `gh stack sync` can briefly publish code whose local evidence is pending; the affected PRs remain blocked from merging until immediate post-sync validation passes.
+- Merge-forward remains available and preserves completed checkpoints, at the cost of additional merge commits.

+# Agent Note: GitHub 原生堆叠与可选 PR rebase
+
+Status: implemented
+
+[English](2026-08-02-native-github-stacks-and-optional-rebases.md) | 中文
+
+## 问题
+
+仅以 base 分支表示的依赖 PR（Pull Request）链没有官方的堆叠身份。要让它落地，就必须逐个手动合并 PR、保留中间分支、调整每个子 PR 的 base，并重新查证这条链是否仍然完整。GitHub 原生的堆叠 PR 功能则会承载顺序，对每一层应用 trunk 规则和 CI，并负责自底向上的合并与 base 调整。
+
+一概禁止改写已评审分支，也会排除原生的 `gh stack` 同步工作流：该工作流通过级联 rebase 更新每个活跃层，并在 lease 保护下发布。如果只在堆叠之外实施这项禁令，就会让独立 PR 和堆叠 PR 面临不一致的历史选择。
+
+## 决策
+
+同一仓库内由两个或更多个相互依赖的 PR 组成的每条链，在落地前都必须使用 GitHub 的官方 stack 对象。以实时 `PullRequest.stack` 和 `stackEntry.position` 字段为权威依据。对于尚未形成官方堆叠且所有 PR 作者相同的链，系统使用 `gh stack link` 按自底向上的顺序自动关联；作者不一或作者信息不可用时，必须取得用户确认。缺少原生支持或跨 fork 的链会使流程硬性停止。如果现有成员属于相互冲突的堆叠，或者官方顺序与分支拓扑不一致，则在解散或重建任何堆叠之前都必须取得用户指示。
+
+「落地堆叠」通过 `gh stack merge  --yes --merge` 合并整个官方堆叠。部分落地需要明确指定边界 PR，并合并从底部到该 PR 的前缀。工作流绝不回退到逐个执行 `gh pr merge` 和手动调整 base。原生直接合并要么全部成功，要么全部不合并；合并队列可能分组处理所选 PR，因此只有每个所选 PR 都分别达到 `MERGED`，落地才算完成。
+
+merge-forward 和 rebase 都可以作为独立 PR 与官方堆叠 PR 的历史刷新方式，包括评审后。改写远端历史时，必须使用精确 lease 或受 lease 保护的 `gh stack` 推送路径；如果远端已经前移，操作必须中止。禁止直接使用 `--force`。[增量更新 base 的决策](2026-07-26-incremental-pr-base-retargeting.md)仍负责 merge-forward 选项。
+
+相关检查通常在发布前运行。`gh stack sync` 是明确的例外，因为它在一次操作中完成获取、级联 rebase 和推送：随后立即验证每个已改写的层；这些验证通过前，不得合并任何受影响的 PR。每次改写推送后，都要重新审计当前 head、未解决的评审线程、批准状态、可合并性和检查结果，因为先前的 commit OID 和内联锚点可能已经过时。
+
+## 验证
+
+[堆叠落地 skill（技能）](../../../skills/dsh-merging-stacked-prs/SKILL.md)验证原生支持、同仓库分支、实时作者信息、官方成员关系与顺序、合并范围以及最终合并状态。[堆叠评审指南](../../../../docs/cookbook/responding-to-pr-review-on-a-stack.md)让修复留在引入问题的层，并涵盖两种用于传播修复的历史策略。[推送前工作流](../../../skills/dsh-pre-push-checks/SKILL.md)负责 lease 保护和同步后立即验证所得的证据。
+
+## 曾考虑的替代方案
+
+**仅以分支链表示堆叠。** 这种做法保留手动流程，但 GitHub 没有 stack 对象可用于展示顺序、对每一层执行 trunk 规则或以原子操作合并整个范围。
+
+**采用原生堆叠，但禁止在评审后使用其 rebase 命令。** 这会保持 commit OID 稳定，但也会在堆叠正在接受评审时禁用官方同步路径，并让独立 PR 遵循不同的政策。
+
+**要求每次刷新 PR 都使用 rebase。** 线性历史很有价值，但当保存已经完成的冲突解决及其恢复点比紧凑历史更重要时，合并检查点仍然是有效选择。
+
+**自动解散相互冲突的堆叠。** 这会让本地分支推断凌驾于共享的 GitHub 元数据之上，并可能干扰所请求链之外的 PR 或作者；已经合并或进入队列的条目不一定都能移除。
+
+## 后果
+
+- 评审者和自动化会获得 GitHub 的堆叠图、覆盖整个堆叠的规则、CI 和原生合并状态。
+- 同一作者的遗留链无需额外询问即可成为官方堆叠；链由多名作者共同拥有或元数据发生冲突时，仍保留人工决策边界。
+- 评审后，rebase 可能使 commit hash、批准状态或评论锚点失效，因此每次改写推送后都要对实时评审状态和检查结果进行审计。
+- `gh stack sync` 可能短暂发布本地验证仍待完成的代码；受影响的 PR 在同步后立即验证通过前仍禁止合并。
+- merge-forward 仍然可用，并以增加合并提交为代价保留已完成的检查点。

-# Merging a stacked PR chain
+# Landing an official GitHub PR stack
 
-This skill is the landing procedure for a dependent PR stack. The standing orders it rests on — merge commits only (`gh pr merge --merge`), never rewrite a pushed branch — live in the root [AGENTS.md](../../../AGENTS.md) § Conventions; the discipline for handling review comments across a stack before it lands is the [responding-to-pr-review-on-a-stack](../../../docs/cookbook/responding-to-pr-review-on-a-stack.md) cookbook guide.
+Land dependent PRs through GitHub's native stack object and `gh stack merge`. Do not reproduce stack semantics by merging and retargeting individual PRs with `gh pr merge` and `gh pr edit`. The root [AGENTS.md](../../../AGENTS.md) owns the allowed merge-forward and rebase histories; the [stack review guide](../../../docs/cookbook/responding-to-pr-review-on-a-stack.md) owns review-fix propagation.
 
-## The hazard this prevents
+## Require native stack support
 
-On GitHub, **deleting a PR's base branch auto-closes that PR.** In a stack `A ← B ← C` (B bases on A, C bases on B), branch A is the base of PR B, and branch B is the base of PR C. So if you merge A with `--delete-branch`, GitHub closes PR B before it's merged — silently destroying the chain. The whole procedure below exists to avoid that: **merge one at a time, retarget each dependent as you go, and delete nothing until every PR has landed.**
+Run `gh stack --version` before changing GitHub state. Hard-stop if the official extension or server-side stack feature is unavailable; do not fall back to the legacy manual landing procedure. GitHub stacks require every head branch to live in the same repository, so hard-stop on a cross-fork chain.
 
-## The procedure
+Use a clean dedicated worktree. Fetch current PR metadata and exact head OIDs rather than trusting branch names or an earlier report:
 
-Given `A ← B ← C` landing on `master`:
+```sh
+gh pr view  --json number,author,baseRefName,baseRefOid,headRefName,headRefOid,isCrossRepository,state,isDraft,reviewDecision,mergeStateStatus,statusCheckRollup
+```
 
-1. **Merge PR A into master, keeping its branch.** `gh pr merge A --merge` — no `--delete-branch`. Branch A must survive because PR B still bases on it. Before touching the next link, confirm the merge actually landed: with required checks pending or a merge queue, `gh pr merge` may only enable auto-merge and return early, so wait until `gh pr view A --json state` reports `MERGED`. This applies after every merge in the stack.
+Query `PullRequest.stack` and `stackEntry.position` for at least one PR in each apparent chain; this official GitHub object, not base-branch inference alone, is the stack-membership authority. Paginate `entries` when `size` exceeds the returned page:
 
-2. **Retarget PR B, refresh it, then merge it — keeping its branch.**
-   - `gh pr edit B --base master` (now that A is in master, B's base becomes master).
-   - Merge the new master *into* branch B: check out B, `git fetch origin`, `git merge origin/master` — merge `origin/master`, not local `master`, because `gh pr merge` updated only GitHub and the local branch is stale — resolve any conflicts here, and push. This makes B current and surfaces conflicts in the working branch where they can be tested — not as a surprise at the GitHub merge.
-   - If `origin/master` moves during that work, finish and push the in-progress merge, then fetch and merge the newer tip in a separate commit. Never abandon or rewrite the earlier work ([rationale](../../notes/implemented/process/2026-07-26-incremental-pr-base-retargeting.md)).
-   - `gh pr merge B --merge` — still no `--delete-branch` (PR C bases on branch B).
+```sh
+gh api graphql -F owner= -F name= -F number= -f query='
+query($owner: String!, $name: String!, $number: Int!) {
+  repository(owner: $owner, name: $name) {
+    pullRequest(number: $number) {
+      number
+      author { login }
+      baseRefName
+      headRefName
+      stackEntry { position }
+      stack {
+        number
+        baseRefName
+        size
+        entries(first: 100) {
+          nodes {
+            position
+            pullRequest { number author { login } baseRefName headRefName state isDraft }
+          }
+        }
+      }
+    }
+  }
+}'
+```
 
-3. **Retarget PR C, refresh it, then merge it — keeping its branch.** Same steps: `gh pr edit C --base master`, fetch and merge `origin/master` into branch C, resolve conflicts there and push, then `gh pr merge C --merge` without `--delete-branch`.
+Establish the expected bottom-to-top order from the live PR bases: the bottom targets the trunk, and each higher PR targets the head branch immediately below it.
 
-4. **Only after every PR (A, B, C) is merged, delete the branches** — local and remote, for all of A, B, C.
+## Link missing stack members
 
-## Why "merge new master into the dependent before merging it"
+First compare any existing stack entries with the expected chain. One existing stack may contain an order-preserving subset of the requested chain; multiple stack numbers, an unexpected entry, or a conflicting order requires user direction before any mutation.
 
-Each retarget step merges the freshly-updated master back into the dependent branch *before* merging the PR. This keeps each PR's diff clean (it only shows that PR's own changes, not the parent's) and forces conflicts to surface in the working branch, where you can build and test the resolution — instead of letting GitHub attempt a blind merge that may conflict or quietly mis-resolve.
+When any dependent PR is not yet in that official stack:
 
-## Verify before deleting anything
+1. Compare every `author.login` exactly.
+2. If all authors match, link the chain automatically in bottom-to-top order:
 
-Before deleting a branch, ask GitHub directly whether any open PR still bases on it:
+```sh
+gh stack link --base    ... 
+```
+
+3. If authors differ or any author is unavailable, ask the user whether to link before changing GitHub state.
+4. Re-query GraphQL and require one stack number, the expected trunk, the complete PR set, and the expected positions and base chain.
+
+Never dissolve, reorder, or rebuild an existing stack automatically; `gh stack link` is additive and merged or queued entries cannot be unstacked.
+
+## Refresh only when needed
+
+Do not rewrite branches merely because a refresh mechanism exists. When the live merge state or repository rules require an updated trunk, choose either allowed history:
+
+- **Native cascading rebase:** check out the remote stack with `gh stack checkout ` when it is not tracked locally, then run `gh stack sync`. The command may rebase and lease-protected force-push every active layer before local validation. Immediately inspect the rewritten scope, run the relevant checks for every affected layer, and do not merge or claim readiness until they pass. If sync detects a rebase conflict, use `gh stack rebase`, resolve and validate it, then publish with `gh stack push`. If checkout or sync reports divergent local and remote stack compositions, cancel and ask rather than deleting or recreating the remote stack automatically.
+- **Incremental merge-forward:** merge the trunk into the bottom affected branch, then propagate each updated parent into its child in bottom-to-top order and push normally. If the base advances during an in-progress merge, preserve that checkpoint before merging the newer tip as specified by the [incremental-retargeting note](../../notes/implemented/process/2026-07-26-incremental-pr-base-retargeting.md).
+
+Any history rewrite is allowed after review, but it invalidates commit-OID assumptions. Re-fetch exact heads and re-audit unresolved review threads, approvals, mergeability, and checks after the push. Never use raw `--force` or overwrite a concurrently advanced remote head.
+
+## Preflight the merge range
+
+Re-query the official stack immediately before merging. Require every selected PR to be open, non-draft, in the expected order, and compliant with the repository's review and check requirements. Treat each PR's state independently; a ready top layer does not prove its dependencies are ready.
+
+"Land the stack" selects the whole stack. A partial landing requires an explicit boundary PR and includes every layer from the bottom through that boundary.
+
+## Merge through the stack API
+
+Merge the whole stack by its official stack number:
+
+```sh
+gh stack merge  --yes --merge
+```
+
+For an explicitly requested partial landing, merge through the boundary PR:
+
+```sh
+gh stack merge  --yes --merge
+```
+
+Do not pass `--delete-branch`, manually retarget dependents, or issue per-PR merge commands. GitHub merges the selected range bottom-up and retargets/rebases any remaining upper layers. A direct stack merge is all-or-nothing; when the trunk uses a merge queue, GitHub queues the selected range together but may land it in separate groups.
+
+Do not bypass merge requirements. If the native merge reports a blocker, inspect and resolve that blocker through the owning PR or stop and report it; never fall back to `gh pr merge`.
+
+## Verify the landed state
+
+Wait for every selected PR to report `MERGED`; a queued request is not a completed landing:
+
+```sh
+gh pr view  --json number,state,mergedAt,mergeCommit,baseRefName,headRefName
+```
+
+For a partial landing, re-query the official stack and verify that every remaining PR is still linked in the expected order and targets the stack trunk or the layer below it. Re-check current heads, review state, and CI because GitHub may have rebased the remaining layers.
+
+Delete branches only in a separate final pass after the corresponding PRs report `MERGED`. Before deleting each branch, require GitHub to report no open PR still using it as a base:
 
 ```sh
 gh pr list --state open --base  --json number --jq length
 ```
 
-Anything other than `0` means open PRs still base on `` and deleting it would auto-close them — do not delete it. The `--base` filter is applied server-side, so zero-versus-non-zero is exact no matter how many PRs are open; the printed number itself saturates at `gh`'s `--limit` (default 30), which never matters here because only `0` clears a delete. Default to merging without `--delete-branch` throughout, and do the deletions as a separate final pass once every branch you're about to delete reports `0`.
+Anything other than `0` blocks deletion.
 
-## Longer chains
+## Checklist
 
-The pattern extends to any depth. For `A ← B ← C ← D ← …`, walk the stack from the bottom up: merge the lowest, then for each next link retarget to master, fetch and merge `origin/master` into it, merge the PR — always without deleting — and only sweep up all the branches at the very end. The invariant never changes: **a branch may be deleted only when no open PR bases on it.**
-
-## Quick checklist
-
-- [ ] Merge bottom PR first, `--merge`, no `--delete-branch`; wait until `gh pr view  --json state` shows `MERGED`.
-- [ ] For each dependent: `gh pr edit  --base master` → fetch and merge `origin/master` into the branch (resolve conflicts there, push) → `gh pr merge  --merge`, no `--delete-branch`; again wait for `MERGED`.
-- [ ] Before each branch delete: `gh pr list --state open --base  --json number --jq length` prints `0`.
-- [ ] Delete all branches (local + remote) only as a final pass.
+- [ ] Native `gh stack` support is available; every PR branch is in the same repository.
+- [ ] Live PR bases and exact heads establish one bottom-to-top dependency chain.
+- [ ] GraphQL reports one official stack with the expected trunk, entries, and order; an eligible same-author unstacked chain was linked automatically.
+- [ ] Any rewritten layers passed relevant validation, and review threads, approvals, mergeability, and checks were re-audited afterward.
+- [ ] The whole stack, or an explicitly bounded prefix, was submitted through `gh stack merge --yes --merge`.
+- [ ] Every selected PR reports `MERGED`; any remaining upper layers still form the expected official stack.
+- [ ] Branch deletion happened only after merged-state and zero-dependent verification.

-Review comments may target several PRs in a dependent stack (`A ← B ← C …`). This guide explains how to resolve them without corrupting the stack. The two invariants it rests on are standing orders in the root [AGENTS.md](../../AGENTS.md) § Conventions: merge commits only, and never rewrite a pushed branch.
+Review comments may target several PRs in a dependent stack (`A ← B ← C …`). Keep that chain linked through GitHub's official stacked-PR feature. This guide owns review-fix placement and propagation; the [dsh-merging-stacked-prs](../../.agents/skills/dsh-merging-stacked-prs/SKILL.md) skill owns linkage checks and landing.
 
 ## Ground rules
 
 1. **One worktree per PR branch.** Each PR's fixes happen in that PR's own worktree; parallel fixes never share a checkout.
-2. **Bring a child up to date by merging the parent down** (`git merge ` into the child, a new merge commit). Never rebase/amend/force-push a pushed branch: rewriting diverges it from what the parent PR and GitHub recorded, breaks the stacked-merge graph, and erases the review-fix history.
-3. **A fix lands on the PR that INTRODUCED the issue, then flows down.** When a comment on PR `B` points at code `B` introduced, fix it on `B` and merge `B` into `C` — even if `C` also carries the file. Originating the fix downstream leaves `B` shipping the unfixed code and hides the fix from `B`'s reviewer.
-4. **Each review fix is a separate commit, never an amend.** The "fix review findings" commit documents what the review caught. Amending is fine only for your own not-yet-pushed, not-yet-reviewed work.
+2. **GitHub's stack object is authoritative.** Base branches establish the expected dependency order, while `PullRequest.stack` and `stackEntry.position` prove that GitHub recognizes it. Do not treat a matching branch chain as an official stack without checking those fields.
+3. **A fix lands on the PR that INTRODUCED the issue, then flows up-stack.** When a comment on PR `B` points at code `B` introduced, fix it on `B` and propagate `B` into `C` — even if `C` also carries the file. Originating the fix downstream leaves `B` shipping the unfixed code and hides the fix from `B`'s reviewer.
+4. **Each review fix remains a distinct commit.** A later rebase may change its OID, but do not amend a reviewed fix out of the branch history. Amend only your own not-yet-pushed, not-yet-reviewed work.
+5. **Choose merge-forward or rebase deliberately.** Both histories are allowed after review. A rewritten push must be lease-protected and must abort rather than overwrite a concurrently advanced remote head; raw `--force` is forbidden.
 
 ## Resolve comments through the stack
 
-1. Triage every comment on the merits before acting: verify the claim against the code — a reviewer flagging the right symptom can still mis-diagnose the cause.
-2. Map each accepted finding to its originating PR, fix it there, then merge down the chain in order.
-3. Delegated fixes are trust-but-verify: a sub-agent's report describes intent, not necessarily what landed. Re-run the gates yourself on the actual tree, and for a regression guard, prove it FAILS on the unfixed code (introduce the regression, watch red, revert) — a guard that passes both ways guards nothing. A sub-agent that reframes a problem as already-handled is a signal to dig in personally.
-4. Reply in the review thread (`gh api repos/{owner}/{repo}/pulls/{pr}/comments/{id}/replies`), not as a top-level comment, stating the fix and the commit that carries it.
-5. Before merging the stack, check dependents: deleting a PR's base branch auto-closes the dependent PR — check each branch with `gh pr list --state open --base  --json number --jq length` (non-zero = open dependents), and merge without `--delete-branch` where a child still bases on the branch. The full landing procedure is the [dsh-merging-stacked-prs](../../.agents/skills/dsh-merging-stacked-prs/SKILL.md) skill.
+1. Triage every comment on the merits before acting: verify the claim against the code — a reviewer flagging the right symptom can still misdiagnose the cause.
+2. Map each accepted finding to its originating PR and fix it there.
+3. Propagate the fixed layer through every affected child in order:
+   - **Merge-forward:** merge the fixed parent branch into its child, validate the child, and continue upward. Preserve each in-progress checkpoint under the [incremental-retargeting decision](../../.agents/notes/implemented/process/2026-07-26-incremental-pr-base-retargeting.md).
+   - **Native cascading rebase:** use `gh stack rebase`, validate the rewritten layers, then publish with `gh stack push`; or use `gh stack sync`, which may publish first and therefore requires immediate post-sync validation under [dsh-pre-push-checks](../../.agents/skills/dsh-pre-push-checks/SKILL.md).
+4. Treat delegated fixes as trust-but-verify: a sub-agent's report describes intent, not necessarily what landed. Re-run the gates yourself on the actual tree, and for a regression guard, prove it FAILS on the unfixed code (introduce the regression, watch red, revert) — a guard that passes both ways guards nothing. A sub-agent that reframes a problem as already handled is a signal to dig in personally.
+5. Reply in the review thread (`gh api repos/{owner}/{repo}/pulls/{pr}/comments/{id}/replies`), not as a top-level comment, stating the fix and the current commit or head that carries it.
+6. After any rewritten push, re-read unresolved threads, approvals, mergeability, and checks. A force-pushed commit OID or outdated inline anchor is not current evidence that the finding remains resolved.
+7. Land only through the official stack procedure. If the PRs are not yet linked, the landing skill automatically links a same-author chain, asks before linking mixed authors, and hard-stops when native stack support is unavailable.
 
 ## Verify
 
-- Every fixed PR shows a new commit (no force-push icon in the PR timeline).
-- Each child PR's diff against its parent still shows only its own changes.

-评审意见可能同时针对一条依赖堆叠（`A ← B ← C …`）中的多个 PR（Pull Request）。本指南说明如何在不破坏堆叠的前提下解决这些意见。它依赖的两个不变式是根 [AGENTS.md](../../AGENTS.md) § Conventions 中的常设指令：只用 merge commit，以及永远不改写已推送的分支。
+评审意见可能同时针对一条依赖堆叠（`A ← B ← C …`）中的多个 PR（Pull Request）。请通过 GitHub 官方的堆叠 PR 功能保持这条链的关联。本指南负责评审修复的归属与传播；[dsh-merging-stacked-prs](../../.agents/skills/dsh-merging-stacked-prs/SKILL.md) skill（技能）负责检查关联关系和落地。
 
 ## 基本规则
 
 1. **每个 PR 分支一个 worktree。** 每个 PR 的修复在该 PR 自己的 worktree 中进行；并行修复绝不共享同一个 checkout。
-2. **通过将父分支向下合并来更新子分支**（在子分支中执行 `git merge `，产生一个新的 merge commit）。绝不对已推送的分支做 rebase/amend/force-push：改写会使分支与父 PR 及 GitHub 记录的内容产生分歧，破坏堆叠合并图，并抹去评审修复历史。
-3. **修复落在引入问题的那个 PR 上，然后向下流动。** 当 PR `B` 上的评论指向 `B` 引入的代码时，在 `B` 上修复，再将 `B` 合并到 `C`——即使 `C` 也包含该文件。把修复发起在下游会导致 `B` 带着未修复的代码交付，并对 `B` 的评审者隐藏修复。
-4. **每个评审修复是一个独立 commit，绝不 amend。** "修复评审发现"的 commit 记录了评审捕获的内容。只有你自己尚未推送、尚未评审的工作才可以 amend。
+2. **GitHub 的 stack 对象是权威依据。** base 分支确定预期的依赖顺序，`PullRequest.stack` 和 `stackEntry.position` 则证明 GitHub 已识别该堆叠。未经检查这些字段，不得仅凭分支链吻合就将其视为官方堆叠。
+3. **修复落在引入问题的那个 PR 上，然后沿堆叠向上流动。** 当 PR `B` 上的评论指向 `B` 引入的代码时，在 `B` 上修复，再将 `B` 的变更传播到 `C`，即使 `C` 也包含该文件。把修复发起在下游会导致 `B` 带着未修复的代码交付，并对 `B` 的评审者隐藏修复。
+4. **每项评审修复都保留为独立 commit。** 后续 rebase 可能改变其 OID，但不得通过 amend 把已经评审的修复从分支历史中抹去。只有你自己尚未推送且尚未评审的工作才可以 amend。
+5. **明确选择 merge-forward 或 rebase。** 评审后允许采用这两种历史更新方式。改写历史的推送必须受 lease 保护；如果远端 head 在此期间前移，操作必须中止，不得将其覆盖。禁止直接使用 `--force`。
 
 ## 沿堆叠解决评审意见
 
 1. 在行动之前先就事论事地审视每条评论：对照代码验证其论断——评审者指出了正确的症状，但仍可能误诊原因。
-2. 将每个被接受的发现映射到其发起 PR，在那里修复，然后按顺序沿链向下合并。
-3. 委派的修复需要信任但验证：子 agent（智能体）的报告描述的是意图，不一定是实际落地的内容。请亲自在实际代码树上重新运行门禁；对于回归守卫，要证明它在未修复的代码上**失败**（引入回归、观察变红、再还原）——两种情况都通过的守卫什么也守不住。子 agent 将问题重新定性为「已处理」时，这是一个需要亲自深入的信号。
-4. 在评审线程中回复（`gh api repos/{owner}/{repo}/pulls/{pr}/comments/{id}/replies`），而非发顶层评论；说明修复内容及承载修复的 commit。
-5. 合并堆叠之前，检查依赖方：删除一个 PR 的 base 分支会自动关闭依赖它的 PR。用 `gh pr list --state open --base  --json number --jq length` 检查每个分支（非零 = 有打开的依赖方），当子 PR 仍以该分支为 base 时，合并时不带 `--delete-branch`。完整的落地流程见 [dsh-merging-stacked-prs](../../.agents/skills/dsh-merging-stacked-prs/SKILL.md) skill（技能）。
+2. 将每个被接受的发现映射到其发起 PR，并在那里修复。
+3. 将修复后的层按顺序传播到每个受影响的子 PR：
+   - **Merge-forward：** 将修复后的父分支合并到其子分支，验证子分支，然后继续沿堆叠向上传播。依照[增量更新 base 的决策](../../.agents/notes/implemented/process/2026-07-26-incremental-pr-base-retargeting.md)，保留每个正在处理的检查点。
+   - **原生级联 rebase：** 使用 `gh stack rebase`，验证所有已改写的层，然后通过 `gh stack push` 发布；也可以使用 `gh stack sync`，该命令可能先发布，因此必须按照 [dsh-pre-push-checks](../../.agents/skills/dsh-pre-push-checks/SKILL.md) 在同步后立即验证。
+4. 委派的修复需要信任但验证：子 agent（智能体）的报告描述的是意图，不一定是实际落地的内容。请亲自在实际代码树上重新运行门禁；对于回归守卫，要证明它在未修复的代码上**失败**（引入回归、观察变红、再还原）——两种情况都通过的守卫什么也守不住。子 agent 将问题重新定性为「已处理」时，这是一个需要亲自深入的信号。
+5. 在评审线程中回复（`gh api repos/{owner}/{repo}/pulls/{pr}/comments/{id}/replies`），而非发顶层评论；说明修复内容及当前承载修复的 commit 或 head。
+6. 每次改写推送后，都要重新读取未解决线程、批准状态、可合并性和检查结果。经 force-push 改写的 commit OID 或已过时的内联锚点，都不足以证明该发现当前仍处于已解决状态。
+7. 仅可通过官方堆叠流程落地。如果这些 PR 尚未关联，落地 skill 会自动关联作者相同的链；如果作者不同，则先询问用户；如果原生堆叠支持不可用，则硬性停止流程。
 
 ## 验证
 
-- 每个已修复的 PR 显示一个新 commit（PR 时间线中没有 force-push 图标）。
-- 每个子 PR 相对其父 PR 的 diff 仍然只包含自身的变更。
-- 门禁在堆叠中的每个 PR 上都通过，而不仅仅是顶部。

Subject: [PATCH 334/557] fix(cli): keep session search tools opt-in on shipped
 surfaces

The shipped-roster change made @deepseek-ai/dsh-tool-session-query a
default row of the shared base.cordis.yml, so the TUI and Web surfaces
put the five session-search tools in front of the model. That
contradicts the recorded opt-in stance for the model-facing session
query consumer; the ACP example remains the mounted reference.

Remove the row from the shared base, the now-dangling disabled patch in
the opt-in core-web profile, and the workspace dependency. The
ctx.sessionQuery index stays: the TUI's /resume and the Web content
search consume it directly. Both shipped-composition tests now pin the
20-tool catalog.

+# Agent Note: Session search tools are not a shipped default
+
+Status: implemented
+
+English | [中文](2026-08-02-session-search-not-shipped-default.zh.md)
+
+## Problem
+
+The [shipped-roster decision](2026-07-31-even-out-shipped-tool-rosters.md) made `tool-session-query` a default row of the shared [`base.cordis.yml`](../../../../apps/cli/config/base.cordis.yml), so the shipped TUI and Web surfaces put the five session-search tools (`session_search`, `session_event_search`, `session_trace`, `session_event_trace`, `session_event_read`) in front of the model. That contradicted the [model-facing session-query-tools decision](2026-07-24-model-facing-session-query-tools.md), whose opt-in stance the package README recorded as "shipped host compositions do not mount it by default". The default also shipped a prompt section teaching a prior-work search workflow that no user had asked for.
+
+## Decision
+
+The shipped TUI, Web, and headless surfaces no longer mount `@deepseek-ai/dsh-tool-session-query`: the row is removed from the shared `base.cordis.yml`, the now-dangling `disabled` patch in the opt-in [`core-web.cordis.yml`](../../../../apps/cli/config/core-web.cordis.yml) profile goes with it, and the workspace dependency drops from `apps/cli/package.json`. The consumer stays opt-in exactly as the model-facing-session-query-tools note describes: the ACP example's [`session-query.cordis.yml`](../../../../examples/acp-agent/session-query.cordis.yml) and its snapshot counterpart remain the mounted reference, and a custom composition can mount the package with the timeout and spill policies.
+
+The `ctx.sessionQuery` service itself stays mounted. `session-query-sqlite` remains a base row — the TUI's `session-reference` consumes it for `/resume` — and the Web overlay keeps patching it to an in-memory index for the browser content search. Only the model-facing consumer is removed.
+
+## Alternatives considered
+
+- **Remove the `session-query-sqlite` index too** — rejected because `/resume` and the Web content-search box consume `ctx.sessionQuery` directly; those are host features, not model tools, and dropping the provider would break them.
+- **Keep the row but disable it in each overlay** — rejected because a disabled base row still ships the dependency and invites a one-line re-enable; the recorded opt-in stance wants the consumer absent from shipped surfaces, with the ACP example as the mount reference.
+- **Mount it on the TUI only** — rejected because the shared base is one row set for every surface; a surface-specific mount would reintroduce the roster split the shipped-roster decision removed.
+
+## Consequences
+
+Both surfaces return to the same twenty unconditional tools (plus `glob`/`grep` under ripgrep), and the five session-search schemas and their prompt section leave the default request. The shipped-composition tests on both surfaces pin the smaller catalog, so re-adding session search as a default touches the same tests. Users who want session search mount the consumer from a personal overlay or the ACP example, adding the dependency where they do.

+
+## 问题
+
+[交付清单决策](2026-07-31-even-out-shipped-tool-rosters.md)把 `tool-session-query` 设为共享 [`base.cordis.yml`](../../../../apps/cli/config/base.cordis.yml) 的默认行,于是交付的 TUI 与 Web surface 把这五个会话搜索工具(`session_search`、`session_event_search`、`session_trace`、`session_event_trace`、`session_event_read`)呈现给了模型。这与[面向模型的会话查询工具决策](2026-07-24-model-facing-session-query-tools.md)相抵触,该决策持需显式启用的立场,包 README 将其记录为「shipped host compositions do not mount it by default」。这份默认还交付了一个提示词段,向模型讲授一套既往工作搜索工作流,而没有任何用户要求过。
+
+## 决策
+
+交付的 TUI、Web 与无头 surface 不再挂载 `@deepseek-ai/dsh-tool-session-query`:该行从共享的 `base.cordis.yml` 移除,opt-in 的 [`core-web.cordis.yml`](../../../../apps/cli/config/core-web.cordis.yml) profile 中那条已悬空的 `disabled` patch 也随之删除,workspace 依赖也从 `apps/cli/package.json` 中移除。该消费方仍保持 opt-in,与面向模型的会话查询工具决策所述完全一致:ACP 示例的 [`session-query.cordis.yml`](../../../../examples/acp-agent/session-query.cordis.yml) 及其快照对侧文件仍是挂载参考,自定义组合也可以连同超时与 spill 策略一起挂载该包。
+
+`ctx.sessionQuery` 服务本身保持挂载。`session-query-sqlite` 仍是 base 的一行,TUI 的 `session-reference` 消费它来实现 `/resume`,Web overlay 也继续把它 patch 成内存索引,供浏览器内容搜索使用。被移除的只有面向模型的消费方。
+
+## 曾考虑的替代方案
+
+- **把 `session-query-sqlite` 索引也一并移除**——否决,因为 `/resume` 和 Web 内容搜索框直接消费 `ctx.sessionQuery`;它们是宿主功能,不是模型工具,移除提供方会破坏它们。
+- **保留该行,但在每个 overlay 中禁用它**——否决,因为一条被禁用的 base 行仍会交付依赖,而且一行就能轻易重新启用;已记录的 opt-in 立场要求消费方不出现在交付的 surface 上,以 ACP 示例作为挂载参考。
+- **只在 TUI 上挂载**——否决,因为共享 base 是所有 surface 共用的一组行;surface 专属挂载会重新引入交付清单决策所消除的清单分裂。
+
+## 后果
+
+两个 surface 都回到同样的二十个无条件工具(ripgrep 可用时再加上 `glob`/`grep`),五个会话搜索 schema 及其提示词段也一并退出默认请求。两个 surface 上的交付组合测试都固定这份更小的目录,因此把会话搜索重新作为默认加回会触及同样的测试。想要会话搜索的用户从个人 overlay 或 ACP 示例挂载该消费方,并在挂载处添加依赖。

+# Agent Note: Continuable background subagents
+
+Status: proposed

+
+## Problem
+
+The subagent tool treats each delegation as one owned `SubagentRun`: foreground calls and background Tasks collect the result and then dispose the run. Disposal bounds the number of live child Agents and releases their scoped services, listeners, and provider resources. The persisted child session may survive, but the parent has no durable catalog or tool path for discovering that child and starting another turn on it.
+
+A Task, a run, and a child session have different lifetimes. A Task represents one background turn and has one terminal result. A `SubagentRun` owns one activation of a child. A persisted child session may contain many turns initiated by the parent or a human. Continuation must preserve per-run disposal rather than retain every historical child Agent in memory.
+
+## Proposal
+
+A continuable background subagent is a durable child session with a series of Task-backed activations. The child session id, transcript, lineage, and declared composition survive in persistence. Each initial or resumed activation creates a fresh Task, `AgentHandle`, and `SubagentRun`, drives one turn, collects its result, and disposes the run before the Task becomes terminal.
+
+The Task's result and cancellation boundary belong to the child activation, not to whichever caller supplied its first message. Task access is authorized by the parent session id, while the Task registry retains the exact live parent Agent instance for notification and teardown. Parent and human messages therefore share one activation result while the parent remains its runtime owner:
+
+```text
+durable child Session
+  activation 1: Task 1 -> SubagentRun -> AgentHandle -> dispose
+  activation 2: Task 2 -> SubagentRun -> AgentHandle -> dispose
+  activation 3: Task 3 -> SubagentRun -> AgentHandle -> dispose
+```
+
+Foreground delegation keeps its current one-shot behavior. The first continuable implementation covers background in-process spawn and fork children. A provider must support persisted cold resume before its children are advertised as continuable; ACP children remain one-shot until the deferred ACP continuation work below is complete.
+
+The low-level `ctx.subagents` seam remains collection-, Task-, and persistence-agnostic. It registers providers, validates and dispatches `start` or `resume`, observes run lifecycle, and returns holder-owned runs. A separate `SubagentControlService` in `@deepseek-ai/dsh-subagent-control` owns stable continuable-child ids, descriptor persistence and lookup by known child id, Task-backed activation, and message routing. The provider-bound `@deepseek-ai/dsh-tool-subagent` plugin and human-facing adapters call that control service for continuable background work; foreground one-shot delegation still calls `ctx.subagents.start()` directly. The globally named model tool is a thin adapter in `@deepseek-ai/dsh-tool-subagent-control`. Parent-to-child enumeration and `list_agents` are specified separately by the [durable subagent catalog](2026-07-22-durable-subagent-catalog-and-list-agents.md).
+
+### Task and cancellation ownership
+
+The initial background delegation asks the control service to start the child and register its Task. Task settlement awaits the result, calls `run.dispose()`, and only then records the `TaskOutcome`; `task_kill` aborts the active run, whose settlement path still disposes it. A terminal Task therefore leaves the durable child session but no live child Agent.
+
+Every later turn creates another Task. Its producer resources cover only that activation, never the child session. It reaches one terminal status, has one result, and is never reopened. The exact live parent Agent remains the Task registry owner: disposing that instance cancels, awaits, and removes its Tasks. Task APIs authorize a caller whose session id matches that owner, but a same-id replacement does not become the notification or teardown target. This preserves the existing `settleRun()` contract and bounds Task-owned live children by concurrent work rather than historical session count.
+
+Opening a child session in a human-facing adapter reads its persisted transcript and does not resume an Agent merely to display it. Human input starts or joins the same Task-backed activation used by parent input through the control service. A human-started Task retains the exact currently loaded parent Agent as its notification target, and `task_output` remains the single result path. The existing completion listener injects at most one unsolicited notice while the Task is unreported; `kill`, a terminal read, or a terminal wait may mark it reported and suppress that notice. The first version therefore permits human interaction only while that parent instance remains live. A user-owned conversation that may outlive the parent and explicitly merge a conclusion back belongs to [interactive side sessions](2026-07-08-interactive-side-sessions.md), not this Task-owned lifecycle.
+
+`TaskService.start()` rejects producers when no Task control surface is attached. A human-facing adapter that accepts child input must therefore attach a Task control surface, or run in a deployment that loads `@deepseek-ai/dsh-tool-tasks`; loading the Task service alone is insufficient. This dependency is the cost of using the same Task result, cancellation, and notification path for parent- and human-started activations.
+
+Cancellation always targets the whole current activation. If human and parent messages have joined one turn, either caller's cancellation aborts that turn, disposes its run, and settles its Task as `killed`; the messages do not have independent results or cancellation rights. Independent cancellation requires a later message to start a separate turn instead of steering the current one.
+
+A cold-resume Task creates its activation-owned `AbortController` before descriptor lookup or any provider await and passes that signal through `SubagentControlService.resume()`, `SubagentService.resume()`, and `SubagentProvider.resume?()`. A persistence call that has no signal need not stop its underlying I/O, but the control service rechecks cancellation after every such await and cannot begin or publish child work afterward. Before Agent publication, abort makes the provider reject only after its creation transaction has rolled back and reached quiescence. After publication, the provider closes the creation-signal handoff race, attaches the same signal to the live run before returning it, and cancellation stops the child turn. `task_kill` and exact-owner disposal use this path even when provider resume has not returned a `SubagentRun`; Task settlement waits for rollback or run disposal and records `killed` only after the activation is quiescent.
+
+### Active run association
+
+The control service keeps a process-local association from child session id to its current Task and, after provider publication, its run. It installs the Task association before awaiting provider start or resume, fills in the returned run, and removes the association only after run disposal and Task terminal publication. This association exists only so parent and human senders can find the same activation; it is not a durable catalog, public `ManagedSubagent`, admission reservation, or run-state machine.
+
+For a continuable initial activation, the control service allocates the stable child session id before Task creation and passes it in the resolved provider start request; in-process spawn and fork publish that exact id instead of allocating one internally. The background tool acknowledgement exposes both identities as `started subagent  as task `. The child id names the durable conversation across activations, while the Task id names only the current activation. A failed initial Task or a process exit before the first child flush can leave an **unmaterialized child**: the caller holds a child id without a durable header and descriptor. Later by-id control operations report that id as unavailable, and durable enumeration omits it.
+
+The first version admits every continuable child turn through this Task-backed path. A non-terminal Task is the only supported live activation; when no activation exists, its run has already been disposed and the durable child is resumable. Before routing any by-id operation, the control service synchronously compares its association with `ctx.agents.get(childId)`. A registry Agent with no association, or a registry Agent different from the associated `run.localAgent`, is an ownership conflict: the control service fails rather than adopting an idle Agent or attaching an untracked turn. When neither exists, cold resume may proceed; a competing publication after that check still loses at the Agent registry collision boundary.
+
+Routing follows the Task association. A running Task accepts live delivery through the run's optional strict `SubagentRun.steer` capability. An absent Task starts a fresh Task and cold-resumes the child. In-process spawn and fork implement this capability by synchronously requiring `AgentStatus.running` before calling `Agent.steer()`; the check and call contain no asynchronous boundary. Providers must not expose the Agent-level idle fallback as strict steering, because that fallback may start an untracked turn after the observed run has ended. If the Task settles between association lookup and this strict check, `steer()` fails, `send_message` reports the message as not delivered, and that call does not fall through to cold resume; a later retry after Task terminal may start the next activation.
+
+The first version does not serialize two callers that concurrently observe a stopped child, nor does it model a separate settling phase between result production and disposal. Concurrent cold-resume attempts may both create Tasks, but the Agent registry permits only one same-session Agent to publish; a losing Task fails and its message is not delivered. Delivery racing startup, cancellation, completion, or cleanup may also fail. These limitations are explicit rather than hidden behind a larger lifecycle abstraction.
+
+Atomic process-local admission is on hold. The smallest follow-up would synchronously reserve the child before awaiting resume, conceptually with `Map>`; later callers would await the same publication promise and then use strict live delivery. This would close duplicate cold resume without adding a public `ManagedSubagent` or explicit `starting`/`running`/`settling` protocol.
+
+### Model-facing `send_message`
+
+The model receives one `send_message(subagent_id, message)` tool backed by `SubagentControlService.sendMessage()`. The control operation owns steer-or-resume orchestration and is distinct from the run's `SubagentRun.steer?()`, which only delivers to an already active run. The tool performs no lifecycle routing of its own. It lives in a separately loaded `@deepseek-ai/dsh-tool-subagent-control` package so provider-bound `@deepseek-ai/dsh-tool-subagent` instances can continue registering distinct delegation tools for spawn, fork, or ACP without registering duplicate global control tools.
+
+- If the child has a running Task and live-steering capability, the service calls `run.steer(message)` and returns the existing Task id; it creates no Task of its own.
+- If the child has no running Task, `send_message` creates a fresh Task, cold-resumes the durable session with the message, and returns the new Task id.
+- If the active provider cannot accept live delivery, strict steering loses a race with Task settlement, or a live child exists outside the Task association, `send_message` fails rather than silently starting, resuming, or adopting an untracked turn.
+
+The service result identifies the route as `steered` with the existing Task id or `started` with the new Task id. Failure is explicit and says that the message was not delivered. The model-facing tool renders these distinctions so timing-dependent routing is observable to the caller.
+
+A delivered message has no independent result: its effect is reflected in the current Task's eventual result. A started follow-up has the fresh Task's result and existing `task_output` read path. The subagent layer adds no second completion injection.
+
+Human input uses the same control operation. The UI may display the child transcript and current Task state, while cancellation calls the Task service with the loaded parent as caller. Tool schema and UI adapters are consumers of one control-service contract rather than separate execution paths.
+
+### Durable child handle and cold resume
+
+The control service snapshots every descriptor input with [`snapshotJsonValue`](../../../../packages/core/session/src/json.ts) before Task creation, matching the detached lossless-JSON boundary already used by Agent messages. A child-scoped setup contribution appends one model-hidden `subagent/descriptor` event after the initial child `turn/start` and before its first request; it carries no `surfaceOp`, remains outside model history, and reaches persistence with that turn's flush. The append-only log retains this non-surface event when compaction replaces surface history. A known child id is resumable only when loading that child session yields a supported descriptor and its header identifies the caller as the direct parent.
+
+The versioned descriptor contains the subagent provider name, resolved child `agentOptions.provider` and `agentOptions.model`, and optional `persona` and `toolFilter`. It does not snapshot the merge-extensible `AgentOptions` object: unrelated extension values cannot make continuation fail merely because they are not JSON. It deliberately omits `subagentDepth`; cold resume relies on the persisted header's `delegationDepth` rather than reconstructing depth from the descriptor. `outputSchema` belongs to one activation's result contract rather than durable child composition. The child header remains authoritative for the child id, `cwd`, `parentSession`, `seedLength`, and `delegationDepth`, while the persisted child transcript owns the fork seed and subsequent history. [`delegationDepthOf()`](../../../../packages/subagent/subagent/src/index.ts) takes the maximum of header and runtime values, so reconstructed runtime options may deepen the persisted value but never lower it and a resumed child cannot regain a top-level delegation budget.
+
+Cold resume cannot depend on an optional method of the old `SubagentRun`, because that run has been disposed and is not retained across process restart. This proposal removes `SubagentRun.resume?()`: a run represents one disposable activation and exposes only activation-scoped operations. It also renames the existing `SubagentRun.sendMessage?()` capability to `SubagentRun.steer?()` so its strict live-only contract cannot be confused with service orchestration or the model-facing tool.
+
+`SubagentControlService.resume()` loads the known child session, folds its descriptor, authorizes the persisted `parentSession`, and creates the Task. It passes a fully resolved request, including the Task-owned cancellation signal, to the low-level `SubagentService.resume(provider, request)`, whose only responsibility is capability-checked provider dispatch and the ordinary run lifecycle observation used by `start`. The selected `SubagentProvider.resume?()` owns transport-specific reconstruction and returns a fresh run. Presence of the provider method is the continuation capability, so no redundant capability flag is added. `SubagentControlService.sendMessage()` chooses between the associated run's `steer?()` operation and this cold-resume path. Neither the low-level service nor a provider enumerates durable children or associates Tasks.
+
+The background tool validates and snapshots descriptor inputs before calling `TaskService.start()`. A synchronous validation failure rejects the tool call and creates no Task. The tool otherwise returns the child and Task ids immediately, without waiting for child publication or descriptor durability. Child creation, first-turn persistence, or descriptor persistence failure disposes any published run and settles the already-created Task as `failed`; the model observes that failure through the ordinary Task completion or `task_output` path. The first implementation reconstructs in-process spawn and fork composition under the currently loaded parent scope. A fork resume loads the child's own persisted transcript, which already contains the completed-turn prefix captured at initial creation; it never forks the parent's newer history again. Resuming a parent does not eagerly resume its children.
+
+TODO (ACP continuation): persist the remote ACP session id as provider-specific descriptor data and implement `AcpProvider.resume?()` as spawn, initialize, `loadSession`, then prompt. The initial ACP run must verify `initialize.agentCapabilities.loadSession`, and every resumed process must use the same durable backend; replayed history from `loadSession` must not be collected as the new activation's output. Because ACP load support is negotiated per child rather than established solely by the provider method's presence, this follow-up must also define how a start result advertises child-specific continuation before ACP children enter the durable catalog.
+
+### Result and notification ownership
+
+Every continuable child activation has exactly one Task and one `TaskOutcome`, regardless of whether the parent or a human supplied the first message. The generic Task reporting contract may inject at most one unsolicited completion notice to the retained parent owner while the Task is unreported; reads, waits, and cancellation may suppress it. Running delivery joins that activation and creates neither a second Task nor a second result. The child transcript remains the human-facing detailed record; Task output remains the parent-facing final result.
+
+Task records and active-run associations are process-local. Persistence makes the child session resumable after restart, but does not recover an interrupted Task, its result, or its notification. Durable Task recovery is a separate concern.
+
+### Implementation boundary
+
+One implementation PR delivers this proposal: stable child-id allocation and provider handoff, the child-session descriptor event, `SubagentControlService`, in-process provider cold resume, existing background-delegation routing, strict spawn/fork steering, active-run association, human message routing, and the separately loaded `@deepseek-ai/dsh-tool-subagent-control` package with its `send_message` tool. Parent-to-child enumeration and `list_agents` consume this durable child-handle contract but remain a separate feature and PR. ACP continuation is a separate provider follow-up after the child-specific advertisement contract above is resolved.
+
+## Alternatives considered
+
+**Retain every background child after Task settlement.** This is the Codex-style resident-session model: follow-up delivery is cheap, but historical children retain Agent scopes, session memory, listeners, and provider resources until an explicit residency limit or eviction policy removes them. Per-activation disposal uses persistence as the continuation boundary and preserves the current resource bound.
+
+**Let human turns run without Tasks.** A parent message joining such a turn has no Task result or completion notice, and UI cancellation has unclear effects on the parent's contribution. Giving every activation one Task makes completion and cancellation properties of the child turn rather than its initiating caller.
+
+**Keep one Task for the lifetime of a child session.** A terminal Task cannot naturally become running again, and one result cannot represent multiple turns. Fresh activation-scoped Tasks preserve the generic Task contract.
+
+**Create a Task for every message.** Steering joins an existing turn and has no independent final result, so a Task created for steering would duplicate the active Task or report a result it does not own. Only a message that starts an activation creates a Task.
+
+**Split `send_message` and `follow_up`.** Separate strict operations expose an implementation-state distinction to the model without removing stopped-child races. One operation follows the Claude Code model: deliver to running work or resume a new Task-backed lifecycle.
+
+**Keep `resume?()` on the disposed run.** Retaining a disposed `SubagentRun` only to call `resume()` makes the old run double as a durable child handle and cannot reconstruct that object after restart. Service dispatch plus provider reconstruction makes the persistence boundary explicit.
+
+**Put control orchestration on `SubagentService`.** This would let one service look up descriptors, associate Tasks, and dispatch providers, but would make the collection-agnostic provider seam depend on one consumer's persistence and Task policy. A separate control service keeps start/resume transport reusable by foreground and non-Task consumers while giving tools and UI one orchestration path.
+
+**Add explicit activation phases.** Public `starting`/`running`/`settling` states could describe admission and cleanup precisely, but would add a lifecycle protocol that the first implementation does not otherwise need. The on-hold promise reservation closes duplicate process-local cold resume without exposing those phases.
+
+## Acceptance criteria
+
+- Initial and resumed continuable activations create a fresh Task and dispose their run before that Task becomes terminal.
+- Opening a persisted child for display creates no Agent activation; human input under a loaded parent starts or joins a Task-backed activation.
+- Human and parent messages delivered to one running activation share its Task result and cancellation outcome.
+- Cancelling a human-started activation aborts and disposes its run and settles the Task as `killed`; its completion notice follows the generic at-most-one reporting contract and may be suppressed when the Task is already reported.
+- A cold-resume Task owns its AbortSignal before descriptor lookup; cancellation during lookup or provider resume prevents later publication or cancels the published run, and Task settlement waits for rollback or disposal quiescence before reporting `killed`.
+- A human-facing adapter attaches a Task control surface before accepting child input; absence of a surface fails clearly instead of starting untracked work.
+- `send_message` delivers to a running child without creating a Task and cold-resumes a stopped child into a fresh Task-backed activation.
+- `send_message` reports whether it `steered` an existing Task or `started` a new Task, including the relevant Task id, and reports a failure as not delivered.
+- Initial continuable delegation allocates its child id before Task creation, passes that id through provider publication, and returns both the stable child id and activation Task id to the model.
+- Spawn and fork implement strict `SubagentRun.steer` behavior with no asynchronous boundary between the running check and `Agent.steer()`; live delivery cannot fall back to an untracked Agent turn.
+- If strict steering loses a race with Task settlement, `send_message` reports the message as not delivered and does not cold-resume within that call.
+- `SubagentRun` has no cold-resume operation; `SubagentControlService.sendMessage()` dispatches active delivery to `run.steer?()` and inactive delivery through low-level `SubagentService.resume()` to `SubagentProvider.resume?()`.
+- The `SubagentRun.sendMessage?()` to `steer?()` rename and the background activation route update the seam module JSDoc, package READMEs, core-data-structures catalog, and `tool-subagent` `settleRun` ownership documentation and tests in the same PR.
+- `SubagentService` remains unaware of Tasks and durable descriptors; `SubagentControlService` owns continuable activation, authorization, descriptor lookup by known child id, and Task/run association for tool and UI consumers.
+- Every supported continuable child turn installs its Task association before provider awaits and retains it through run disposal; by-id routing rejects a live `ctx.agents.get(childId)` unless the association exists and its `run.localAgent` is that exact Agent.
+- A known persisted child id can be authorized and lazily reconstructed after parent resume with equivalent declared composition under the resumed parent's scope; fork resume uses only the child's persisted transcript and never re-forks current parent history.
+- Descriptor inputs are snapshotted before Task creation; a versioned model-hidden descriptor event is turn-enclosed in the child session, excluded from the surface, retained across compaction, and folded only after the child header passes direct-parent authorization. The descriptor omits `subagentDepth`, and resumed depth uses the persisted header as its monotone floor.
+- Invalid descriptor JSON rejects the tool without creating a Task, while asynchronous child or descriptor persistence failure disposes the run and settles the returned Task as `failed`.
+- Provider-bound delegation tools remain in `@deepseek-ai/dsh-tool-subagent`; the globally named `send_message` tool registers once from `@deepseek-ai/dsh-tool-subagent-control`.
+- Each activation produces one Task result and at most one unsolicited existing Task completion notice; reads, waits, or cancellation may suppress that notice, and steering and the subagent layer add no duplicate notification.
+- Tests document that concurrent stopped-child admission is not atomic: one same-session publication wins, a losing Task fails, and the losing message is not reported as delivered.
+- Keyless package tests cover Task ownership, disposal ordering, human start and cancellation, running delivery, cold follow-up, descriptor rejection and rollback, known-id reconstruction, scope reconstruction, and terminal cleanup. Model-visible tool and transcript changes have runnable snapshot coverage.
+
+## Risks
+
+- Every follow-up after settlement pays persistence load and scoped setup cost. Continuable creation fails clearly when persistence is unavailable or the stored composition cannot be reconstructed.
+- Two callers may concurrently observe a stopped child and start competing resumes. The Agent registry prevents duplicate same-session publication, but a losing Task fails and its message is not delivered. A message may also race cancellation, terminal status publication, or run disposal. The first version does not claim atomic or exactly-once admission; the on-hold process-local promise reservation can close duplicate cold resume without requiring a public lifecycle state machine.
+- Driving a continuable child through the ordinary Agent API bypasses its Task association. The control service rejects that live child as an ownership conflict; adapters must display persisted transcripts without loading an Agent and submit human input through `SubagentControlService.sendMessage()`.

+# Agent Note: 可继续的后台 subagent
+
+Status: proposed
+
+[English](2026-07-21-continuable-background-subagents.md) | 中文
+
+## 问题
+
+subagent 工具将每次委派视为一个独占的 `SubagentRun`：前台调用和后台 Task 收集结果后 dispose（资源释放）该 run。这种所有权关系能够限制存活 child agent（智能体）的数量，并释放其作用域服务、监听器及提供方资源。持久化的 child 会话可能继续存在，但 parent 缺少持久化目录和工具路径，无法发现该 child 并为其启动另一轮次。
+
+Task、run 和 child 会话具有不同的生命周期。一个 Task 表示一轮后台执行，并且只有一个终态结果。一个 `SubagentRun` 拥有 child 的一次激活。一个持久化 child 会话可以包含多个由 parent 或用户发起的轮次。继续执行必须保留逐 run dispose 的约定，而不能把所有历史 child agent 都留在内存中。
+
+## 提案
+
+一个可继续的后台 subagent，是由一系列 Task 支撑的短期激活共同组成的持久化 child 会话。child session id、transcript（文本记录）、谱系及声明的组合配置均保留在持久化存储中。每次初始激活或恢复激活都会创建新的 Task、`AgentHandle` 和 `SubagentRun`，驱动一个轮次、收集结果，并在 Task 进入终态前 dispose 该 run。
+
+Task 的结果和取消边界属于 child 激活，不属于为该激活提供第一条消息的调用方。Task 访问根据 parent session id 授权，而 Task 注册表仍保留当前存活的精确 parent Agent 实例，用于通知与资源清理。因此，只要 parent 仍是运行时 owner，parent 消息和用户消息便会共享同一个激活结果：
+
+```text
+durable child Session
+  activation 1: Task 1 -> SubagentRun -> AgentHandle -> dispose
+  activation 2: Task 2 -> SubagentRun -> AgentHandle -> dispose
+  activation 3: Task 3 -> SubagentRun -> AgentHandle -> dispose
+```
+
+前台委派保持当前的一次性行为。第一版可继续实现覆盖进程内 spawn 和 fork child。提供方只有支持从持久化存储恢复后，才能将其 child 标记为可继续；在下述 ACP（Agent Client Protocol）后续工作完成前，ACP child 仍保持一次性行为。
+
+底层 `ctx.subagents` seam 不感知 child 集合、Task 与持久化。它注册提供方，校验并分发 `start` 或 `resume`，观察 run 生命周期，并返回由持有方负责的 run。`@deepseek-ai/dsh-subagent-control` 中单独的 `SubagentControlService` 负责管理可继续 child 的稳定 id、持久化描述符并按已知 child id 查找、由 Task 支撑的激活，以及消息路由。按提供方绑定的 `@deepseek-ai/dsh-tool-subagent` 插件及面向用户的适配器通过该控制服务处理可继续后台工作；前台一次性委派仍直接调用 `ctx.subagents.start()`。全局命名的模型工具是 `@deepseek-ai/dsh-tool-subagent-control` 中的轻量适配器。parent 到 child 的枚举与 `list_agents` 由单独的[持久化 subagent 目录](2026-07-22-durable-subagent-catalog-and-list-agents.md)规定。
+
+### Task 与取消的所有权
+
+初始后台委派请求控制服务启动 child 并注册其 Task。Task 结算流程等待结果，调用 `run.dispose()`，然后才记录 `TaskOutcome`；`task_kill` 中止活跃 run，其结算路径仍会 dispose 该 run。因此，终态 Task 会留下持久化 child 会话，但不会留下存活的 child agent。
+
+后续每个轮次都会创建另一个 Task。该轮 producer 持有的执行资源仅服务于这次激活，不属于 child 会话。它只会到达一次终态、只产生一个结果，也不会重新打开。Task 注册表中当前注册的那个存活 parent agent 实例仍是其 owner：dispose 该实例会取消、等待并移除其 Task。Task API 会授权 session id 与该 owner 匹配的调用方，但 id 相同的替代实例不会成为通知或资源清理目标。这一设计保留现有 `settleRun()` 契约，并使 Task 所拥有的存活 child 数量受并发工作量限制，而不是随历史会话数量增长。
+
+用户界面适配器打开 child 会话时，只读取持久化 transcript，不会仅为展示而恢复 agent。用户输入通过控制服务，启动或加入与 parent 输入相同的 Task 激活。由用户启动的 Task 会保留当前加载的精确 parent Agent 作为通知目标，`task_output` 仍是唯一结果路径。只要 Task 尚未标记为已报告，现有完成监听器最多注入一条主动通知；`kill`、终态读取或终态等待都可能将其标记为已报告，并抑制这条通知。第一版仅允许在该 parent 实例保持存活时进行用户交互。可以比 parent 存活更久、并将结论显式合并回去的用户自有会话属于[交互式 side session](2026-07-08-interactive-side-sessions.md)，不属于这一由 Task 持有的生命周期。
+
+如果没有附加 Task 控制面，`TaskService.start()` 会拒绝 producer。因此，接受 child 输入的用户界面适配器必须附加 Task 控制面，或运行于加载了 `@deepseek-ai/dsh-tool-tasks` 的部署中；仅加载 Task 服务并不足够。这项依赖是 parent 和用户启动的激活共用 Task 结果、取消和通知路径所付出的代价。
+
+取消始终作用于当前完整激活。如果用户消息和 parent 消息已经加入同一个轮次，任一调用方发起取消都会中止该轮次、dispose 其 run，并将对应 Task 结算为 `killed`；这些消息没有独立的结果或取消权。若需要独立取消，后续消息必须另起轮次，而不能加入当前轮次。
+
+从持久化存储恢复的 Task 会在查找描述符或等待任何提供方操作之前，创建由本次激活持有的 `AbortController`，并通过 `SubagentControlService.resume()`、`SubagentService.resume()` 和 `SubagentProvider.resume?()` 逐层传递其信号。对于不接受信号的持久化调用，可以让底层 I/O 执行完毕；但控制服务必须在每次这类 await 返回后重新检查取消状态，如已取消，之后不得开始或发布任何 child 工作。在 Agent 发布前收到中止信号时，提供方必须先回滚其创建事务并达到完全停稳状态，然后才让恢复调用以拒绝结束。Agent 发布后，提供方必须消除创建期间移交取消信号时的竞态，在返回前将同一信号附加到存活 run；之后取消会停止 child 轮次。即使提供方的恢复调用尚未返回 `SubagentRun`，`task_kill` 与对确切 owner 实例的 dispose 仍通过这条路径生效。Task 结算会等待回滚或 run dispose 完成，只有在激活完全停稳后才记录 `killed`。
+
+### 活跃 run 关联
+
+控制服务在进程内维护 child session id 到当前 Task 的关联，并在提供方发布后将 run 填入该关联。它会在等待提供方 start 或 resume 之前安装 Task 关联，填入返回的 run，并且只在 run dispose 完成且 Task 终态发布后才移除该关联。该关联只用于让 parent 发送方和用户发送方找到同一次激活；它不是持久化 child 目录、公开的 `ManagedSubagent`、准入预留或 run 状态机。
+
+对于可继续 child 的初始激活，控制服务会在创建 Task 前分配稳定的 child session id，并通过已完全解析的提供方启动请求传递该 id；进程内 spawn 和 fork 会发布这一确切 id，而不是在内部另行分配。后台工具的确认消息会同时公开两种标识，格式为 `started subagent  as task `。child id 在多次激活中始终指代同一个持久化对话，Task id 则只指代当前激活。初始 Task 失败，或进程在 child 首次 flush 之前退出，都可能留下一个 **unmaterialized child**：调用方持有 child id，但不存在持久化 header 和描述符。后续按 id 的控制操作会报告该 id 不可用，持久化枚举也不会列出它。
+
+第一版要求每个可继续 child 轮次都通过这条由 Task 支撑的路径准入。非终态 Task 是唯一受支持的存活激活；不存在激活时，其 run 已被 dispose，持久化 child 可以恢复。在路由任何按 id 的操作之前，控制服务会同步将自身关联与 `ctx.agents.get(childId)` 比较。如果注册表中的 Agent 没有关联，或者它与所关联的 `run.localAgent` 不同，就属于所有权冲突：控制服务会失败，而不会接管 idle Agent 或附加未受跟踪的轮次。二者均不存在时，可以从持久化存储恢复；如果检查后又有竞争方发布，仍会在 Agent 注册表的冲突边界上失败。
+
+系统依据 Task 关联进行路由。运行中的 Task 通过 run 可选且严格的 `SubagentRun.steer` 功能接收在线消息。Task 不存在时，系统创建新 Task，并从持久化存储恢复 child。进程内 spawn 和 fork 通过以下方式实现该功能：调用 `Agent.steer()` 前同步要求 `AgentStatus.running`，检查与调用之间不存在异步边界。提供方不得将 Agent 层的 idle fallback 暴露为严格 steering（中途引导），因为观察到的 run 结束后，该 fallback 可能启动一个未受 Task 跟踪的轮次。如果 Task 在查找关联与执行这项严格检查之间进入结算，`steer()` 会失败，`send_message` 会报告消息未送达，而且该次调用不会改用从持久化存储恢复路径；在 Task 终态发布后重试，才可能启动下一次激活。
+
+第一版不会串行化两个同时观察到 child 已停止的调用方，也不会为结果产生与 dispose 之间的阶段单独建立 settling 状态。并发的 cold resume 尝试可能都会创建 Task，但 agent 注册表只允许一个相同会话的 agent 完成发布；失败的 Task 不会送达其消息。发送也可能因与启动、取消、完成或清理发生竞态而失败。本提案明确接受这些限制，不为此引入更大的生命周期抽象。
+
+原子的进程内准入暂缓实现。最小的后续方案是在等待 resume 之前同步预留 child，概念上使用 `Map>`；后续调用方等待同一个发布 promise，再使用严格的在线消息功能。这样无需添加公开的 `ManagedSubagent` 或显式 `starting`／`running`／`settling` 协议，即可消除重复的 cold resume。
+
+### 面向模型的 `send_message`
+
+模型获得一个由 `SubagentControlService.sendMessage()` 支撑的 `send_message(subagent_id, message)` 工具。控制操作负责在 steering 与恢复之间编排；它不同于 run 的 `SubagentRun.steer?()`，后者只能向已活跃的 run 发送消息。工具本身不执行生命周期路由。该工具位于单独加载的 `@deepseek-ai/dsh-tool-subagent-control` 包中，因此按提供方绑定的 `@deepseek-ai/dsh-tool-subagent` 实例可以继续为 spawn、fork 或 ACP 注册不同的委派工具，而不会重复注册全局控制工具。
+
+- 如果 child 存在运行中的 Task 并支持在线消息，服务会调用 `run.steer(message)` 并返回现有 task id；它不会创建新 Task。
+- 如果 child 没有运行中的 Task，`send_message` 会创建新 Task，使用该消息从持久化存储恢复会话，并返回新的 task id。
+- 如果活跃提供方无法接收在线消息、严格 steering 在与 Task 结算的竞态中失败，或 Task 关联之外存在存活 child，`send_message` 会失败，而不会静默启动、恢复或接管未受跟踪的轮次。
+
+服务结果将路由标识为 `steered` 并携带现有 task id，或标识为 `started` 并携带新的 task id。失败结果会明确说明消息未送达。面向模型的工具会呈现这些差异，让调用方能够观察由时序决定的实际路由。
+
+发送到现有 run 的消息没有独立结果，其效果体现在当前 Task 的最终结果中。启动的后续轮次具有新 Task 的结果，并使用现有 `task_output` 读取路径。subagent 层不会再注入第二份完成通知。
+
+用户输入使用同一个控制操作。UI 可以展示 child transcript 和当前 Task 状态，取消操作则以已加载 parent 作为调用方访问 Task 服务。工具 schema 与 UI 适配器消费同一个控制服务契约，不建立彼此独立的执行路径。
+
+### 持久化 child handle 与从持久化存储恢复
+
+控制服务在创建 Task 前，通过 [`snapshotJsonValue`](../../../../packages/core/session/src/json.ts) 对每项描述符输入建立快照；这一边界与 Agent 消息现有的分离式无损 JSON 边界一致。作用于 child 作用域的 setup contribution 会在 child 初始 `turn/start` 之后、首次请求之前追加一个对模型隐藏的 `subagent/descriptor` 事件。该事件不携带 `surfaceOp`，不进入模型历史，并随该轮次的 flush 一并进入持久化存储。当压缩替换 surface 历史时，仅追加日志仍保留这个不属于 surface 的事件。只有在加载已知 child id 对应的 child 会话后能得到受支持的描述符，且会话 header 将调用方标识为直接 parent 时，该 id 才可恢复。
+
+版本化描述符包含 subagent 提供方名称、已解析的 child `agentOptions.provider` 和 `agentOptions.model`，以及可选的 `persona` 与 `toolFilter`。它不会对可通过声明合并扩展的 `AgentOptions` 对象建立快照：与此无关的扩展值不会仅因无法表示为 JSON 而导致继续执行失败。描述符会特意省略 `subagentDepth`；从持久化存储恢复时，系统依赖持久化 header 中的 `delegationDepth`，而不根据描述符重建深度。`outputSchema` 属于单次激活的结果契约，不属于持久化 child 组合配置。child header 仍是 child id、`cwd`、`parentSession`、`seedLength` 和 `delegationDepth` 的权威信息，持久化 child transcript 则负责保存 fork seed 和后续历史。[`delegationDepthOf()`](../../../../packages/subagent/subagent/src/index.ts) 会在 header 值和运行时值中取最大值，因此重建后的运行时选项可以加深持久化值，但绝不能降低它，恢复后的 child 无法重新获得顶层委派预算。
+
+从持久化存储恢复不能依赖旧 `SubagentRun` 的可选方法，因为该 run 已被 dispose，并且进程重启后不会保留。本提案删除 `SubagentRun.resume?()`：run 表示一次可 dispose 的激活，只暴露作用于当前激活的操作。本提案还将现有 `SubagentRun.sendMessage?()` 功能改名为 `SubagentRun.steer?()`，以免其严格的仅在线契约与服务编排或面向模型的工具混淆。
+
+`SubagentControlService.resume()` 会加载已知 child 会话、归并其描述符、根据持久化的 `parentSession` 鉴权，并创建 Task。它向底层 `SubagentService.resume(provider, request)` 传递完全解析的请求，其中包含由 Task 持有的取消信号；后者只负责检查提供方功能后进行分发，并执行 `start` 所使用的普通 run 生命周期观察。选中的 `SubagentProvider.resume?()` 负责传输相关的重建，并返回一个新 run。提供方是否存在该方法本身就是继续执行功能，无需额外功能标志。`SubagentControlService.sendMessage()` 在关联 run 的 `steer?()` 操作与该持久化恢复路径之间做出选择。底层服务和提供方都不会枚举持久化 child 或关联 Task。
+
+后台工具会在调用 `TaskService.start()` 前校验描述符输入并建立快照。同步校验失败会拒绝工具调用，且不会创建 Task。除此之外，工具会立即返回 child id 和 Task id，不等待 child 发布或描述符持久化完成。child 创建、首轮持久化或描述符持久化失败时，系统会 dispose 所有已发布的 run，并将已经创建的 Task 结算为 `failed`；模型通过普通 Task 完成通知或 `task_output` 路径观察该失败。第一版会在当前已加载的 parent 作用域下重建进程内 spawn 和 fork 组合配置。恢复 fork 时只加载 child 自己的持久化 transcript，其中已经包含初始创建时捕获的已完成轮次前缀；系统绝不会再次 fork parent 更新后的历史。恢复 parent 不会立即恢复其 child。
+
+TODO（ACP 继续执行）：将远端 ACP session id 作为提供方专用描述符数据持久化，并实现 `AcpProvider.resume?()`，依次执行 spawn、initialize、`loadSession` 和 prompt。初始 ACP run 必须检查 `initialize.agentCapabilities.loadSession`，恢复后的每个进程必须使用同一个持久化后端；`loadSession` 回放的历史消息不得计入新激活的输出。由于 ACP 的加载支持是按 child 协商的，不能仅根据提供方是否存在该方法来确定，因此该后续工作还必须定义 start 结果如何声明单个 child 支持继续执行，之后才能将 ACP child 写入持久化目录。
+
+### 结果与通知所有权
+
+每次可继续 child 激活都恰好拥有一个 Task 和一个 `TaskOutcome`，无论第一条消息由 parent 还是用户提供。只要 Task 尚未标记为已报告，通用 Task 报告契约最多会向保留的 parent owner 注入一条主动完成通知；读取、等待和取消都可能抑制该通知。发送到运行中激活的消息会加入该激活，不会创建第二个 Task 或第二份结果。child transcript 是面向用户的详细记录；Task 输出是面向 parent 的最终结果。
+
+Task 记录和活跃 run 关联都位于进程内。持久化使 child 会话可在重启后恢复，但不会恢复中断的 Task、其结果或通知。持久化 Task 恢复属于另一个问题。
+
+### 实现边界
+
+一个实现 PR 会交付本提案：稳定 child id 的分配与提供方交接、child 会话描述符事件、`SubagentControlService`、进程内提供方从持久化存储恢复、现有后台委派路由、严格的 spawn／fork steering、活跃 run 关联、用户消息路由，以及单独加载的 `@deepseek-ai/dsh-tool-subagent-control` 包及其 `send_message` 工具。parent 到 child 的枚举与 `list_agents` 使用这份持久化 child handle 契约，但仍是单独的功能和 PR。解决上述按 child 声明支持的契约后，再通过单独的提供方改动支持 ACP 继续执行。
+
+## 已考虑的替代方案
+
+**在 Task 结算后保留所有后台 child。** 这是 Codex 风格的常驻会话模型：发送后续消息成本较低，但历史 child 会持续占用 agent 作用域、会话内存、监听器和提供方资源，直至显式常驻数量上限或淘汰策略将其移除。逐激活 dispose 使用持久化作为继续执行边界，同时保留当前的资源上限。
+
+**允许用户轮次不使用 Task。** parent 消息加入此类轮次后，没有对应的 Task 结果或完成通知；UI 取消对 parent 所发消息的影响也不明确。让每次激活都拥有一个 Task，可使完成与取消成为 child 轮次的属性，而不是初始调用方的属性。
+
+**在 child 会话整个生命周期内复用一个 Task。** 终态 Task 无法自然地再次进入运行状态，一个结果也无法表示多个轮次。每次激活创建新 Task 可以保留通用 Task 契约。
+
+**为每条消息创建 Task。** 发送到现有 run 的消息会加入已有轮次，不产生独立的最终结果；为这类消息创建 Task，会重复当前 Task，或报告一个它并不拥有的结果。只有启动新激活的消息才会创建 Task。
+
+**拆分 `send_message` 与 `follow_up`。** 两个严格操作会向模型暴露实现状态差异，却无法消除 child 已停止时的竞态。单一操作采用 Claude Code 模型：向运行中的工作发送消息，或恢复一个由新 Task 支撑的生命周期。
+
+**在已 dispose 的 run 上保留 `resume?()`。** 如果仅为调用 `resume()` 而保留已 dispose 的 `SubagentRun`，旧 run 会同时充当持久化 child handle，而且进程重启后无法重建该对象。由服务分发、提供方重建，可明确表达持久化边界。
+
+**将控制编排放在 `SubagentService` 上。** 这样一个服务就能查找描述符、关联 Task 并分发提供方，但会迫使不感知集合的提供方 seam 依赖某个消费方的持久化与 Task 策略。单独的控制服务让前台及不使用 Task 的消费方可以复用 start／resume 传输，同时为工具和 UI 提供统一的编排路径。
+
+**增加显式激活阶段。** 公开的 `starting`／`running`／`settling` 状态可以准确描述准入和清理，但会引入第一版实现并不需要的生命周期协议。暂缓实现的 promise 预留无需暴露这些阶段，即可消除进程内重复的 cold resume。
+
+## 验收标准
+
+- 初始及恢复后的可继续激活都会创建新 Task，并在该 Task 进入终态前 dispose 对应 run。
+- 打开持久化 child 仅用于展示时，不会创建 agent 激活；在 parent 已加载时，用户输入会启动或加入一个由 Task 支撑的激活。
+- 用户消息和 parent 消息发送到同一个运行中激活后，共享其 Task 结果和取消结果。
+- 取消用户启动的激活会中止并 dispose 对应 run，将 Task 结算为 `killed`；其完成通知遵循通用的至多一次报告契约，并且在 Task 已标记为已报告时可能被抑制。
+- 从持久化存储恢复的 Task 在描述符查找前就持有其 AbortSignal；查找描述符或执行提供方恢复期间发生取消时，系统不得在之后发布 run，若 run 已发布则会取消它。Task 只有在回滚或 dispose 完成、激活完全停稳后，才结算为 `killed`。
+- 用户界面适配器在接受 child 输入前会附加 Task 控制面；缺少控制面时明确失败，而不会启动未受跟踪的工作。
+- `send_message` 向运行中的 child 发送消息时不会创建 Task；向已停止的 child 发送消息时，会从持久化存储恢复并创建新的 Task 激活。
+- `send_message` 会以 `steered` 报告消息已加入现有 Task，或以 `started` 报告已启动新 Task，并携带相应 task id；失败时会报告消息未送达。
+- 初始可继续委派在创建 Task 前分配 child id，通过提供方发布路径传递该 id，并向模型返回稳定的 child id 与当前激活的 Task id。
+- spawn 和 fork 实现严格的 `SubagentRun.steer` 行为；检查运行状态与调用 `Agent.steer()` 之间不存在异步边界，在线消息不会 fallback 到未受跟踪的 Agent 轮次。
+- 严格 steering 在与 Task 结算的竞态中失败时，`send_message` 会报告消息未送达，而且不会在该次调用中从持久化存储恢复。
+- `SubagentRun` 不提供从持久化存储恢复的操作；`SubagentControlService.sendMessage()` 将活跃消息分发至 `run.steer?()`，将非活跃消息经由底层 `SubagentService.resume()` 分发至 `SubagentProvider.resume?()`。
+- `SubagentRun.sendMessage?()` 到 `steer?()` 的重命名和后台激活路由，会在同一 PR 中同步更新 seam 模块 JSDoc、各包 README、core-data-structures 目录，以及 `tool-subagent` 中 `settleRun` 的所有权文档和测试。
+- `SubagentService` 不感知 Task 与持久化描述符；`SubagentControlService` 负责可继续激活、鉴权、按已知 child id 查找描述符，以及工具和 UI 消费方使用的 Task／run 关联。
+- 每个受支持的可继续 child 轮次都会在等待提供方之前安装 Task 关联，并保留该关联直到 run dispose 完成；按 id 路由会拒绝存活的 `ctx.agents.get(childId)`，除非关联已存在，且其 `run.localAgent` 就是该 Agent。
+- parent 恢复后，系统可以对已知的持久化 child id 鉴权，并在恢复后的 parent 作用域下，以等价的声明式组合配置按需重建该 child；恢复 fork 时只使用 child 的持久化 transcript，绝不重新 fork parent 的当前历史。
+- 描述符输入会在创建 Task 前建立快照；带版本、对模型隐藏的描述符事件位于 child 会话轮次内，不属于 surface，在压缩后仍保留，并且只有在 child header 通过直接 parent 鉴权后才会被归并。描述符省略 `subagentDepth`，恢复时的深度以持久化 header 中的值为单调下界。
+- 描述符 JSON 无效会拒绝工具调用且不创建 Task，异步 child 创建或描述符持久化失败则会 dispose 对应 run，并将已经返回的 Task 结算为 `failed`。
+- 按提供方绑定的委派工具仍位于 `@deepseek-ai/dsh-tool-subagent`；全局命名的 `send_message` 工具由 `@deepseek-ai/dsh-tool-subagent-control` 注册一次。
+- 每次激活只产生一个 Task 结果和至多一条现有 Task 主动完成通知；读取、等待或取消可能抑制该通知，steering 和 subagent 层不会添加重复通知。
+- 测试记录已停止 child 的并发准入并非原子操作：一个相同会话的发布成功，失败的 Task 进入失败状态，且其消息不会被报告为已送达。
+- 无密钥包测试覆盖 Task 所有权、dispose 顺序、用户启动和取消、运行中消息、持久化后续轮次、描述符拒绝与回滚、按已知 id 重建、作用域重建，以及所有终态下的清理。面向模型的工具及 transcript 变更具有可运行的快照覆盖。
+
+## 风险
+
+- 每次完成结算后的后续轮次都需要承担持久化加载和作用域 setup 成本。持久化不可用或存储的组合配置无法重建时，可继续 child 的创建会明确失败。
+- 两个调用方可能同时观察到 child 已停止，并启动相互竞争的恢复。agent 注册表会阻止相同会话的重复发布，但失败的 Task 不会送达其消息。消息也可能与取消、终态发布或 run dispose 发生竞态。第一版不承诺原子准入或恰好执行一次语义；暂缓实现的进程内 promise 预留无需公开生命周期状态机，即可消除重复的 cold resume。
+- 通过普通 Agent API 驱动可继续 child 会绕过其 Task 关联。控制服务会将该存活 child 视为所有权冲突并拒绝；适配器必须在不加载 Agent 的情况下展示持久化 transcript，并通过 `SubagentControlService.sendMessage()` 提交用户输入。
+- 活跃 run 关联只能协调一个运行时。多个进程同时恢复时不会串行化；此类部署需要持久化层的租约或 compare-and-set 操作。
+- 用户交互要求 Task 注册表中作为 owner 的那个 parent agent 实例保持存活，因为 dispose owner 会取消并移除其 Task。用户交互还要求附加 Task 控制面。若要单独与 child 交互，后续必须将 Task 访问所有权与持久化通知目标分离。
+- 后台工具会在 child 发布和描述符持久化之前返回 child id 和 Task id。启动失败、持久化失败，或进程在 child 首次 flush 之前退出，都可能留下 unmaterialized child id；按 id 的控制操作会报告该 id 不可用，持久化枚举也不会列出它，而不会追溯修改工具返回结果。
+- 将显式组合字段持久化到 child 日志后，其无损 JSON 与兼容性契约便成为恢复契约的一部分。后续如需支持其他组合配置输入，必须明确更改描述符版本，不能隐式持久化可通过声明合并扩展的 `AgentOptions` 字段。
+- Task 记录和活跃 run 关联位于进程内，而 child 会话具有持久性。重启会恢复会话，但不会恢复进行中的工作或其 Task 通知。

 Foreground delegation keeps its current one-shot behavior. The first continuable implementation covers background in-process spawn and fork children. A provider must support persisted cold resume before its children are advertised as continuable; ACP children remain one-shot until the deferred ACP continuation work below is complete.
 
-The low-level `ctx.subagents` seam remains collection-, Task-, and persistence-agnostic.

Subject: [PATCH 337/557] feat(subagent): continuable background subagents

Implement the continuable background subagents RFC: a durable child
session with a series of Task-backed activations, each disposing its
run before the Task settles.

- dsh-subagent: rename SubagentRun.sendMessage to strict steer, drop
  run-level resume, add SubagentProvider.resume dispatch via
  SubagentService.resume, the continuation start field, and the
  versioned model-hidden subagent/descriptor session event.
- dsh-subagent-inprocess/-spawn/-fork: publish the control-allocated
  child id, append the descriptor inside the initial turn, implement
  cold resume from the child's own transcript under the live parent
  scope, and strict running-only steer.
- dsh-subagent-control (new): SubagentControlService owning stable
  child ids, descriptor snapshot/fold/authorization, Task-backed
  activation with settle-then-dispose ordering, the process-local
  active-run association, and steer-or-resume sendMessage routing.
- dsh-tool-subagent: background route branches on the provider's
  resume capability (continuable via the control service; one-shot
  task for ACP), returning both child and task ids.
- dsh-tool-subagent-control (new): the globally named send_message
  tool rendering steered/started routes.

Keyless coverage spans Task ownership and disposal ordering, running
delivery, cold follow-up, descriptor rejection and rollback, known-id
reconstruction, kill during lookup, admission races, and a new
subagent-continuable ACP snapshot scenario.

+
+## Problem
+
+The subagent tool treats each delegation as one owned `SubagentRun`: foreground calls and background Tasks collect the result and then dispose the run. Disposal bounds the number of live child Agents and releases their scoped services, listeners, and provider resources. The persisted child session may survive, but the parent has no durable catalog or tool path for discovering that child and starting another turn on it.
+
+A Task, a run, and a child session have different lifetimes. A Task represents one background turn and has one terminal result. A `SubagentRun` owns one activation of a child. A persisted child session may contain many turns initiated by the parent or a human. Continuation must preserve per-run disposal rather than retain every historical child Agent in memory.
+
+## Decision
+
+A continuable background subagent is a durable child session with a series of Task-backed activations. The child session id, transcript, lineage, and declared composition survive in persistence. Each initial or resumed activation creates a fresh Task, `AgentHandle`, and `SubagentRun`, drives one turn, collects its result, and disposes the run before the Task becomes terminal.
+
+The Task's result and cancellation boundary belong to the child activation, not to whichever caller supplied its first message. Task access is authorized by the parent session id, while the Task registry retains the exact live parent Agent instance for notification and teardown. Parent and human messages therefore share one activation result while the parent remains its runtime owner:
+
+```text
+durable child Session
+  activation 1: Task 1 -> SubagentRun -> AgentHandle -> dispose
+  activation 2: Task 2 -> SubagentRun -> AgentHandle -> dispose
+  activation 3: Task 3 -> SubagentRun -> AgentHandle -> dispose
+```
+
+Foreground delegation keeps its one-shot behavior. Continuation covers background in-process spawn and fork children. A provider supports persisted cold resume before its children are advertised as continuable — `tool-subagent` branches its background route on the mounted provider's `resume` capability — and ACP children remain one-shot until the deferred ACP continuation work below is complete.
+
+The low-level `ctx.subagents` seam stays collection-, Task-, and persistence-agnostic. It registers providers, validates and dispatches `start` or `resume`, observes run lifecycle, and returns holder-owned runs. The `SubagentControlService` (`ctx.subagentControl` in `@deepseek-ai/dsh-subagent-control`) owns stable continuable-child ids, descriptor persistence and lookup by known child id, Task-backed activation, and message routing. The provider-bound `@deepseek-ai/dsh-tool-subagent` plugin and human-facing adapters call that control service for continuable background work; foreground one-shot delegation still calls `ctx.subagents.start()` directly. The globally named model tool is a thin adapter in `@deepseek-ai/dsh-tool-subagent-control`. Parent-to-child enumeration and `list_agents` belong to a separate durable-catalog proposal.
+
+### Task and cancellation ownership
+
+The initial background delegation asks the control service to start the child and register its Task. Task settlement awaits the result, calls `run.dispose()` (through the control service's `settleRun`), and only then records the `TaskOutcome`; `task_kill` aborts the active run, whose settlement path still disposes it. A terminal Task therefore leaves the durable child session but no live child Agent.
+
+Every later turn creates another Task. Its producer resources cover only that activation, never the child session. It reaches one terminal status, has one result, and is never reopened. The exact live parent Agent remains the Task registry owner: disposing that instance cancels, awaits, and removes its Tasks. Task APIs authorize a caller whose session id matches that owner, but a same-id replacement does not become the notification or teardown target. This preserves the `settleRun()` contract and bounds Task-owned live children by concurrent work rather than historical session count.
+
+Opening a child session in a human-facing adapter reads its persisted transcript and does not resume an Agent merely to display it. Human input starts or joins the same Task-backed activation used by parent input through the control service. A human-started Task retains the exact currently loaded parent Agent as its notification target, and `task_output` remains the single result path. The existing completion listener injects at most one unsolicited notice while the Task is unreported; `kill`, a terminal read, or a terminal wait may mark it reported and suppress that notice. Human interaction is therefore permitted only while that parent instance remains live. A user-owned conversation that may outlive the parent and explicitly merge a conclusion back belongs to [interactive side sessions](../../proposed/feature/2026-07-08-interactive-side-sessions.md), not this Task-owned lifecycle.
+
+`TaskService.start()` rejects producers when no Task control surface is attached. A human-facing adapter that accepts child input must therefore attach a Task control surface, or run in a deployment that loads `@deepseek-ai/dsh-tool-tasks`; loading the Task service alone is insufficient. This dependency is the cost of using the same Task result, cancellation, and notification path for parent- and human-started activations.
+
+Cancellation always targets the whole current activation. If human and parent messages have joined one turn, either caller's cancellation aborts that turn, disposes its run, and settles its Task as `killed`; the messages do not have independent results or cancellation rights. Independent cancellation requires a later message to start a separate turn instead of steering the current one.
+
+A cold-resume Task creates its activation-owned `AbortController` before descriptor lookup or any provider await; the lookup, direct-parent authorization, and descriptor fold run inside the Task producer, so the same signal covers them and their failures settle that Task as `failed`. A persistence call that has no signal need not stop its underlying I/O, but the control service rechecks cancellation after every such await and cannot begin or publish child work afterward. Before Agent publication, abort makes the provider reject only after its creation transaction has rolled back and reached quiescence. After publication, the provider closes the creation-signal handoff race, attaches the same signal to the live run before returning it, and cancellation stops the child turn. `task_kill` and exact-owner disposal use this path even when provider resume has not returned a `SubagentRun`; Task settlement waits for rollback or run disposal and records `killed` only after the activation is quiescent.
+
+### Active run association
+
+The control service keeps a process-local association from child session id to its current Task and, after provider publication, its run. It installs the Task association before awaiting provider start or resume, fills in the returned run, and removes the association only after run disposal and Task terminal publication. This association exists only so parent and human senders can find the same activation; it is not a durable catalog, public `ManagedSubagent`, admission reservation, or run-state machine.
+
+For a continuable initial activation, the control service allocates the stable child session id before Task creation and passes it in the resolved provider start request (`SubagentStartRequest.continuation`); in-process spawn and fork publish that exact id instead of allocating one internally. The background tool acknowledgement exposes both identities as `started subagent  as task `. The child id names the durable conversation across activations, while the Task id names only the current activation. A failed initial Task or a process exit before the first child flush can leave an **unmaterialized child**: the caller holds a child id without a durable header and descriptor. Later by-id control operations report that id as unavailable (the started Task fails with that detail), and durable enumeration omits it.
+
+Every continuable child turn is admitted through this Task-backed path. A non-terminal Task is the only supported live activation; when no activation exists, its run has already been disposed and the durable child is resumable. Before routing any by-id operation, the control service synchronously compares its association with `ctx.agents.get(childId)`. A registry Agent with no association, or a registry Agent different from the associated `run.localAgent`, is an ownership conflict: the control service fails rather than adopting an idle Agent or attaching an untracked turn. When neither exists, cold resume may proceed; a competing publication after that check still loses at the Agent registry collision boundary.
+
+Routing follows the Task association. A running Task accepts live delivery through the run's optional strict `SubagentRun.steer` capability. An absent Task starts a fresh Task and cold-resumes the child. In-process spawn and fork implement this capability by synchronously requiring `AgentStatus.running` before calling `Agent.steer()`; the check and call contain no asynchronous boundary. Providers must not expose the Agent-level idle fallback as strict steering, because that fallback may start an untracked turn after the observed run has ended. If the Task settles between association lookup and this strict check, `steer()` fails, `send_message` reports the message as not delivered, and that call does not fall through to cold resume; a later retry after Task terminal may start the next activation.
+
+The control service does not serialize two callers that race a stopped child through paths outside it, nor does it model a separate settling phase between result production and disposal. The synchronous association install before the producer's first await admits one activation per child in this process — a competing `sendMessage` during resume load observes the pending activation and fails explicitly — while a bypassing publication still loses at the Agent registry's same-session collision boundary. Delivery racing startup, cancellation, completion, or cleanup may also fail. These limitations are explicit rather than hidden behind a larger lifecycle abstraction.
+
+### Model-facing `send_message`
+
+The model receives one `send_message(subagent_id, message)` tool backed by `SubagentControlService.sendMessage()`. The control operation owns steer-or-resume orchestration and is distinct from the run's `SubagentRun.steer?()`, which only delivers to an already active run. The tool performs no lifecycle routing of its own. It lives in the separately loaded `@deepseek-ai/dsh-tool-subagent-control` package so provider-bound `@deepseek-ai/dsh-tool-subagent` instances can continue registering distinct delegation tools for spawn, fork, or ACP without registering duplicate global control tools.
+
+- If the child has a running Task and live-steering capability, the service calls `run.steer(message)` and returns the existing Task id; it creates no Task of its own.
+- If the child has no running Task, `send_message` creates a fresh Task, cold-resumes the durable session with the message, and returns the new Task id.
+- If the active provider cannot accept live delivery, strict steering loses a race with Task settlement, or a live child exists outside the Task association, `send_message` fails rather than silently starting, resuming, or adopting an untracked turn.
+
+The service result identifies the route as `steered` with the existing Task id or `started` with the new Task id. Failure is explicit and says that the message was not delivered. The model-facing tool renders these distinctions so timing-dependent routing is observable to the caller.
+
+A delivered message has no independent result: its effect is reflected in the current Task's eventual result. A started follow-up has the fresh Task's result and existing `task_output` read path. The subagent layer adds no second completion injection.
+
+Human input uses the same control operation. The UI may display the child transcript and current Task state, while cancellation calls the Task service with the loaded parent as caller. Tool schema and UI adapters are consumers of one control-service contract rather than separate execution paths.
+
+### Durable child handle and cold resume
+
+The control service snapshots every descriptor input with the seam's `snapshotSubagentDescriptor()` (built on [`snapshotJsonValue`](../../../../packages/core/session/src/json.ts)) before Task creation, matching the detached lossless-JSON boundary already used by Agent messages. A child-scoped setup contribution — a one-shot `agent/pre-step` listener installed by the in-process driver — appends one model-hidden `subagent/descriptor` event after the initial child `turn/start` and before its first request; it carries no `surfaceOp`, remains outside model history, and reaches persistence with that turn's flush. The append-only log retains this non-surface event when compaction replaces surface history. A known child id is resumable only when loading that child session yields a supported descriptor in the child's own suffix (after `seedLength`, so a fork seed cannot leak an ancestor's descriptor) and its header identifies the caller as the direct parent.
+
+The versioned descriptor (`SUBAGENT_DESCRIPTOR_VERSION` in [descriptor.ts](../../../../packages/subagent/subagent/src/descriptor.ts)) contains the subagent provider name, resolved child `agentOptions.provider` and `agentOptions.model`, and optional `persona` and `toolFilter`. It does not snapshot the merge-extensible `AgentOptions` object: unrelated extension values cannot make continuation fail merely because they are not JSON. It deliberately omits `subagentDepth`; cold resume relies on the persisted header's `delegationDepth` rather than reconstructing depth from the descriptor. `outputSchema` belongs to one activation's result contract rather than durable child composition. The child header remains authoritative for the child id, `cwd`, `parentSession`, `seedLength`, and `delegationDepth`, while the persisted child transcript owns the fork seed and subsequent history. [`delegationDepthOf()`](../../../../packages/subagent/subagent/src/index.ts) takes the maximum of header and runtime values, so reconstructed runtime options may deepen the persisted value but never lower it and a resumed child cannot regain a top-level delegation budget.
+
+Cold resume cannot depend on an optional method of the old `SubagentRun`, because that run has been disposed and is not retained across process restart. `SubagentRun` has no `resume` operation: a run represents one disposable activation and exposes only activation-scoped operations. The former `SubagentRun.sendMessage?()` capability is named `SubagentRun.steer?()` so its strict live-only contract cannot be confused with service orchestration or the model-facing tool.
+
+`SubagentControlService`'s resume path loads the known child session, folds its descriptor, authorizes the persisted `parentSession`, and runs inside the Task it creates. It passes a fully resolved request, including the Task-owned cancellation signal, to the low-level `SubagentService.resume(provider, request)`, whose only responsibility is capability-checked provider dispatch and the ordinary run lifecycle observation used by `start`. The selected `SubagentProvider.resume?()` owns transport-specific reconstruction (in-process: `parent.ctx.agents.resume` under the currently loaded parent scope) and returns a fresh run. Presence of the provider method is the continuation capability, so no redundant capability flag exists. `SubagentControlService.sendMessage()` chooses between the associated run's `steer?()` operation and this cold-resume path. Neither the low-level service nor a provider enumerates durable children or associates Tasks.
+
+The background tool validates and snapshots descriptor inputs before calling `TaskService.start()`. A synchronous validation failure rejects the tool call and creates no Task. The tool otherwise returns the child and Task ids immediately, without waiting for child publication or descriptor durability. Child creation, first-turn persistence, or descriptor persistence failure disposes any published run and settles the already-created Task as `failed`; the model observes that failure through the ordinary Task completion or `task_output` path. In-process spawn and fork reconstruct composition under the currently loaded parent scope. A fork resume loads the child's own persisted transcript, which already contains the completed-turn prefix captured at initial creation; it never forks the parent's newer history again. Resuming a parent does not eagerly resume its children.
+
+TODO (ACP continuation): persist the remote ACP session id as provider-specific descriptor data and implement `AcpProvider.resume?()` as spawn, initialize, `loadSession`, then prompt. The initial ACP run must verify `initialize.agentCapabilities.loadSession`, and every resumed process must use the same durable backend; replayed history from `loadSession` must not be collected as the new activation's output. Because ACP load support is negotiated per child rather than established solely by the provider method's presence, this follow-up must also define how a start result advertises child-specific continuation before ACP children enter the durable catalog.
+
+### Result and notification ownership
+
+Every continuable child activation has exactly one Task and one `TaskOutcome`, regardless of whether the parent or a human supplied the first message. The generic Task reporting contract may inject at most one unsolicited completion notice to the retained parent owner while the Task is unreported; reads, waits, and cancellation may suppress it. Running delivery joins that activation and creates neither a second Task nor a second result. The child transcript remains the human-facing detailed record; Task output remains the parent-facing final result.
+
+Task records and active-run associations are process-local. Persistence makes the child session resumable after restart, but does not recover an interrupted Task, its result, or its notification. Durable Task recovery is a separate concern.
+
+## Alternatives considered
+
+**Retain every background child after Task settlement.** This is the Codex-style resident-session model: follow-up delivery is cheap, but historical children retain Agent scopes, session memory, listeners, and provider resources until an explicit residency limit or eviction policy removes them. Per-activation disposal uses persistence as the continuation boundary and preserves the current resource bound.
+
+**Let human turns run without Tasks.** A parent message joining such a turn has no Task result or completion notice, and UI cancellation has unclear effects on the parent's contribution. Giving every activation one Task makes completion and cancellation properties of the child turn rather than its initiating caller.
+
+**Keep one Task for the lifetime of a child session.** A terminal Task cannot naturally become running again, and one result cannot represent multiple turns. Fresh activation-scoped Tasks preserve the generic Task contract.
+
+**Create a Task for every message.** Steering joins an existing turn and has no independent final result, so a Task created for steering would duplicate the active Task or report a result it does not own. Only a message that starts an activation creates a Task.
+
+**Split `send_message` and `follow_up`.** Separate strict operations expose an implementation-state distinction to the model without removing stopped-child races. One operation follows the Claude Code model: deliver to running work or resume a new Task-backed lifecycle.
+
+**Keep `resume?()` on the disposed run.** Retaining a disposed `SubagentRun` only to call `resume()` makes the old run double as a durable child handle and cannot reconstruct that object after restart. Service dispatch plus provider reconstruction makes the persistence boundary explicit.
+
+**Put control orchestration on `SubagentService`.** This would let one service look up descriptors, associate Tasks, and dispatch providers, but would make the collection-agnostic provider seam depend on one consumer's persistence and Task policy. A separate control service keeps start/resume transport reusable by foreground and non-Task consumers while giving tools and UI one orchestration path.
+
+**Add explicit activation phases.** Public `starting`/`running`/`settling` states could describe admission and cleanup precisely, but would add a lifecycle protocol the implementation does not otherwise need. The synchronous association install closes duplicate process-local cold resume without exposing those phases.
+
+## Testing
+
+- `packages/subagent/subagent-control/tests/subagent-control.spec.ts` drives the real stack (agent loop, JSONL persistence, spawn/fork providers, Task service and surface, control service) keylessly: initial and resumed activations create fresh Tasks and dispose their runs before terminal; the descriptor event is turn-enclosed, model-hidden, versioned, and durable under the control-allocated child id; `task_kill` during a run or during cold-resume lookup settles `killed` after quiescence with no child work; steering joins the running Task without a second Task; cold follow-ups accumulate turns in one durable transcript with the declared composition reconstructed; fork resume keeps the persisted seed boundary and never re-forks newer parent history; resumed depth uses the persisted header floor; foreign-parent, descriptor-less, and unmaterialized ids fail their started Task with the id unavailable; ownership conflicts and steering-settlement races report not-delivered without cold-resume fallthrough; competing sends during resume load are admitted once.
+- `packages/subagent/tool-subagent-control/tests/tool-subagent-control.spec.ts` pins the `send_message` schema, both route renderings, the not-delivered failure, the no-agent rejection, and HMR disposal.
+- `packages/subagent/tool-subagent/tests/tool-subagent.spec.ts` covers the capability-branched background route: a resumable provider returns both ids through the control service and advertises `send_message`, a one-shot provider keeps the plain task acknowledgement, and a resumable provider without the control service fails loud.
+- The keyless ACP snapshot scenario `subagent-continuable` (examples/acp-agent) pins the model-visible transcript: the two-id acknowledgement, `task_output` collection, and a `send_message` follow-up whose started Task fails with the id unavailable.
+
+## Consequences
+
+- Every follow-up after settlement pays persistence load and scoped setup cost; in exchange, live children stay bounded by concurrent work rather than historical session count. Continuable creation fails clearly when persistence is unavailable or the stored composition cannot be reconstructed.
+- Two callers may still race a stopped child through paths outside the control service. The Agent registry prevents duplicate same-session publication; a losing Task fails and its message is not delivered. A message may also race cancellation, terminal status publication, or run disposal. Admission is not claimed to be atomic or exactly-once; the synchronous process-local association install closes duplicate cold resume through the control service without a public lifecycle state machine.
+- Driving a continuable child through the ordinary Agent API bypasses its Task association. The control service rejects that live child as an ownership conflict; adapters must display persisted transcripts without loading an Agent and submit human input through `SubagentControlService.sendMessage()`.
+- The active-run association coordinates only one runtime. Concurrent resume from multiple processes is not serialized; that deployment requires a persistence-level lease or compare-and-set operation.
+- Human interaction requires the exact parent Agent instance to remain live because owner disposal cancels and removes its Tasks. It also requires an attached Task control surface. Standalone child interaction requires a future separation between Task access ownership and durable notification targeting.
+- The background tool returns child and Task ids before child publication and descriptor durability. Startup failure, persistence failure, or process exit before the first child flush may leave an unmaterialized child id; by-id control reports it as unavailable and durable enumeration omits it rather than retroactively changing the tool result.
+- Persisting explicit composition fields in the child log makes their lossless-JSON and compatibility contract part of resume. Later support for another composition input requires a deliberate descriptor-version change rather than implicitly persisting merge-extensible `AgentOptions` fields.
+- Task records and active-run associations are process-local even though child sessions are durable. Restart recovers the session, not in-flight work or its Task notification.

+# Agent Note: 可继续的后台 subagent
+
+Status: implemented
+
+[English](2026-07-21-continuable-background-subagents.md) | 中文
+
+## 问题
+
+subagent 工具将每次委派视为一个独占的 `SubagentRun`：前台调用和后台 Task 收集结果后 dispose（资源释放）该 run。这种所有权关系能够限制存活 child agent（智能体）的数量，并释放其作用域服务、监听器及提供方资源。持久化的 child 会话可能继续存在，但 parent 缺少持久化目录和工具路径，无法发现该 child 并为其启动另一轮次。
+
+Task、run 和 child 会话具有不同的生命周期。一个 Task 表示一轮后台执行，并且只有一个终态结果。一个 `SubagentRun` 拥有 child 的一次激活。一个持久化 child 会话可以包含多个由 parent 或用户发起的轮次。继续执行必须保留逐 run dispose 的约定，而不能把所有历史 child agent 都留在内存中。
+
+## 决策
+
+一个可继续的后台 subagent，是由一系列 Task 支撑的短期激活共同组成的持久化 child 会话。child session id、transcript（文本记录）、谱系及声明的组合配置均保留在持久化存储中。每次初始激活或恢复激活都会创建新的 Task、`AgentHandle` 和 `SubagentRun`，驱动一个轮次、收集结果，并在 Task 进入终态前 dispose 该 run。
+
+Task 的结果和取消边界属于 child 激活，不属于为该激活提供第一条消息的调用方。Task 访问根据 parent session id 授权，而 Task 注册表仍保留当前存活的精确 parent Agent 实例，用于通知与资源清理。因此，只要 parent 仍是运行时 owner，parent 消息和用户消息便会共享同一个激活结果：
+
+```text
+durable child Session
+  activation 1: Task 1 -> SubagentRun -> AgentHandle -> dispose
+  activation 2: Task 2 -> SubagentRun -> AgentHandle -> dispose
+  activation 3: Task 3 -> SubagentRun -> AgentHandle -> dispose
+```
+
+前台委派保持一次性行为。继续执行覆盖进程内 spawn 和 fork child。提供方支持从持久化存储恢复后，才能将其 child 标记为可继续——`tool-subagent` 会依据所挂载提供方的 `resume` 功能对其后台路由进行分支——在下述 ACP（Agent Client Protocol）后续工作完成前，ACP child 仍保持一次性行为。
+
+底层 `ctx.subagents` seam 不感知 child 集合、Task 与持久化。它注册提供方，校验并分发 `start` 或 `resume`，观察 run 生命周期，并返回由持有方负责的 run。`SubagentControlService`（`@deepseek-ai/dsh-subagent-control` 中的 `ctx.subagentControl`）负责管理可继续 child 的稳定 id、持久化描述符并按已知 child id 查找、由 Task 支撑的激活，以及消息路由。按提供方绑定的 `@deepseek-ai/dsh-tool-subagent` 插件及面向用户的适配器通过该控制服务处理可继续后台工作；前台一次性委派仍直接调用 `ctx.subagents.start()`。全局命名的模型工具是 `@deepseek-ai/dsh-tool-subagent-control` 中的轻量适配器。parent 到 child 的枚举与 `list_agents` 属于单独的持久化目录提案。
+
+### Task 与取消的所有权
+
+初始后台委派请求控制服务启动 child 并注册其 Task。Task 结算流程等待结果，调用 `run.dispose()`（经由控制服务的 `settleRun`），然后才记录 `TaskOutcome`；`task_kill` 中止活跃 run，其结算路径仍会 dispose 该 run。因此，终态 Task 会留下持久化 child 会话，但不会留下存活的 child agent。
+
+后续每个轮次都会创建另一个 Task。该轮 producer 持有的执行资源仅服务于这次激活，不属于 child 会话。它只会到达一次终态、只产生一个结果，也不会重新打开。Task 注册表中当前注册的那个存活 parent agent 实例仍是其 owner：dispose 该实例会取消、等待并移除其 Task。Task API 会授权 session id 与该 owner 匹配的调用方，但 id 相同的替代实例不会成为通知或资源清理目标。这一设计保留 `settleRun()` 契约，并使 Task 所拥有的存活 child 数量受并发工作量限制，而不是随历史会话数量增长。
+
+用户界面适配器打开 child 会话时，只读取持久化 transcript，不会仅为展示而恢复 agent。用户输入通过控制服务，启动或加入与 parent 输入相同的 Task 激活。由用户启动的 Task 会保留当前加载的精确 parent Agent 作为通知目标，`task_output` 仍是唯一结果路径。只要 Task 尚未标记为已报告，现有完成监听器最多注入一条主动通知；`kill`、终态读取或终态等待都可能将其标记为已报告，并抑制这条通知。因此，仅允许在该 parent 实例保持存活时进行用户交互。可以比 parent 存活更久、并将结论显式合并回去的用户自有会话属于[交互式 side session](../../proposed/feature/2026-07-08-interactive-side-sessions.md)，不属于这一由 Task 持有的生命周期。
+
+如果没有附加 Task 控制面，`TaskService.start()` 会拒绝 producer。因此，接受 child 输入的用户界面适配器必须附加 Task 控制面，或运行于加载了 `@deepseek-ai/dsh-tool-tasks` 的部署中；仅加载 Task 服务并不足够。这项依赖是 parent 和用户启动的激活共用 Task 结果、取消和通知路径所付出的代价。
+
+取消始终作用于当前完整激活。如果用户消息和 parent 消息已经加入同一个轮次，任一调用方发起取消都会中止该轮次、dispose 其 run，并将对应 Task 结算为 `killed`；这些消息没有独立的结果或取消权。若需要独立取消，后续消息必须另起轮次，而不能加入当前轮次。
+
+从持久化存储恢复的 Task 会在查找描述符或等待任何提供方操作之前，创建由本次激活持有的 `AbortController`；描述符查找、直接 parent 鉴权和描述符归并都在该 Task producer 内部执行，因此同一信号覆盖它们，其失败会将该 Task 结算为 `failed`。对于不接受信号的持久化调用，可以让底层 I/O 执行完毕；但控制服务必须在每次这类 await 返回后重新检查取消状态，如已取消，之后不得开始或发布任何 child 工作。在 Agent 发布前收到中止信号时，提供方必须先回滚其创建事务并达到完全停稳状态，然后才让恢复调用以拒绝结束。Agent 发布后，提供方必须消除创建期间移交取消信号时的竞态，在返回前将同一信号附加到存活 run；之后取消会停止 child 轮次。即使提供方的恢复调用尚未返回 `SubagentRun`，`task_kill` 与对确切 owner 实例的 dispose 仍通过这条路径生效。Task 结算会等待回滚或 run dispose 完成，只有在激活完全停稳后才记录 `killed`。
+
+### 活跃 run 关联
+
+控制服务在进程内维护 child session id 到当前 Task 的关联，并在提供方发布后将 run 填入该关联。它会在等待提供方 start 或 resume 之前安装 Task 关联，填入返回的 run，并且只在 run dispose 完成且 Task 终态发布后才移除该关联。该关联只用于让 parent 发送方和用户发送方找到同一次激活；它不是持久化 child 目录、公开的 `ManagedSubagent`、准入预留或 run 状态机。
+
+对于可继续 child 的初始激活，控制服务会在创建 Task 前分配稳定的 child session id，并通过已完全解析的提供方启动请求（`SubagentStartRequest.continuation`）传递该 id；进程内 spawn 和 fork 会发布这一确切 id，而不是在内部另行分配。后台工具的确认消息会同时公开两种标识，格式为 `started subagent  as task `。child id 在多次激活中始终指代同一个持久化对话，Task id 则只指代当前激活。初始 Task 失败，或进程在 child 首次 flush 之前退出，都可能留下一个 **unmaterialized child**：调用方持有 child id，但不存在持久化 header 和描述符。后续按 id 的控制操作会报告该 id 不可用（已启动的 Task 会带着该详情失败），持久化枚举也不会列出它。
+
+每个可继续 child 轮次都通过这条由 Task 支撑的路径准入。非终态 Task 是唯一受支持的存活激活；不存在激活时，其 run 已被 dispose，持久化 child 可以恢复。在路由任何按 id 的操作之前，控制服务会同步将自身关联与 `ctx.agents.get(childId)` 比较。如果注册表中的 Agent 没有关联，或者它与所关联的 `run.localAgent` 不同，就属于所有权冲突：控制服务会失败，而不会接管 idle Agent 或附加未受跟踪的轮次。二者均不存在时，可以从持久化存储恢复；如果检查后又有竞争方发布，仍会在 Agent 注册表的冲突边界上失败。
+
+系统依据 Task 关联进行路由。运行中的 Task 通过 run 可选且严格的 `SubagentRun.steer` 功能接收在线消息。Task 不存在时，系统创建新 Task，并从持久化存储恢复 child。进程内 spawn 和 fork 通过以下方式实现该功能：调用 `Agent.steer()` 前同步要求 `AgentStatus.running`，检查与调用之间不存在异步边界。提供方不得将 Agent 层的 idle fallback 暴露为严格 steering（中途引导），因为观察到的 run 结束后，该 fallback 可能启动一个未受 Task 跟踪的轮次。如果 Task 在查找关联与执行这项严格检查之间进入结算，`steer()` 会失败，`send_message` 会报告消息未送达，而且该次调用不会改用从持久化存储恢复路径；在 Task 终态发布后重试，才可能启动下一次激活。
+
+控制服务不会串行化两个通过其外部路径同时争抢已停止 child 的调用方，也不会为结果产生与 dispose 之间的阶段单独建立 settling 状态。在 producer 首次 await 之前同步安装的关联，使本进程内每个 child 只准入一次激活——resume 加载期间竞争的 `sendMessage` 会观察到待处理的激活并显式失败——而绕开该关联的发布仍会在 Agent 注册表相同会话的冲突边界上失败。发送也可能因与启动、取消、完成或清理发生竞态而失败。这些限制是明确的，而非隐藏在更大的生命周期抽象之后。
+
+### 面向模型的 `send_message`
+
+模型获得一个由 `SubagentControlService.sendMessage()` 支撑的 `send_message(subagent_id, message)` 工具。控制操作负责在 steering 与恢复之间编排；它不同于 run 的 `SubagentRun.steer?()`，后者只能向已活跃的 run 发送消息。工具本身不执行生命周期路由。该工具位于单独加载的 `@deepseek-ai/dsh-tool-subagent-control` 包中，因此按提供方绑定的 `@deepseek-ai/dsh-tool-subagent` 实例可以继续为 spawn、fork 或 ACP 注册不同的委派工具，而不会重复注册全局控制工具。
+
+- 如果 child 存在运行中的 Task 并支持在线消息，服务会调用 `run.steer(message)` 并返回现有 task id；它不会创建新 Task。
+- 如果 child 没有运行中的 Task，`send_message` 会创建新 Task，使用该消息从持久化存储恢复会话，并返回新的 task id。
+- 如果活跃提供方无法接收在线消息、严格 steering 在与 Task 结算的竞态中失败，或 Task 关联之外存在存活 child，`send_message` 会失败，而不会静默启动、恢复或接管未受跟踪的轮次。
+
+服务结果将路由标识为 `steered` 并携带现有 task id，或标识为 `started` 并携带新的 task id。失败结果会明确说明消息未送达。面向模型的工具会呈现这些差异，让调用方能够观察由时序决定的实际路由。
+
+发送到现有 run 的消息没有独立结果，其效果体现在当前 Task 的最终结果中。启动的后续轮次具有新 Task 的结果，并使用现有 `task_output` 读取路径。subagent 层不会再注入第二份完成通知。
+
+用户输入使用同一个控制操作。UI 可以展示 child transcript 和当前 Task 状态，取消操作则以已加载 parent 作为调用方访问 Task 服务。工具 schema 与 UI 适配器消费同一个控制服务契约，不建立彼此独立的执行路径。
+
+### 持久化 child handle 与从持久化存储恢复
+
+控制服务在创建 Task 前，通过 seam 的 `snapshotSubagentDescriptor()`（基于 [`snapshotJsonValue`](../../../../packages/core/session/src/json.ts) 构建）对每项描述符输入建立快照；这一边界与 Agent 消息现有的分离式无损 JSON 边界一致。作用于 child 作用域的 setup contribution——由进程内驱动安装的一次性 `agent/pre-step` 监听器——会在 child 初始 `turn/start` 之后、首次请求之前追加一个对模型隐藏的 `subagent/descriptor` 事件。该事件不携带 `surfaceOp`，不进入模型历史，并随该轮次的 flush 一并进入持久化存储。当压缩替换 surface 历史时，仅追加日志仍保留这个不属于 surface 的事件。只有在加载已知 child id 对应的 child 会话后，能在该 child 自身的后缀中（`seedLength` 之后，因此 fork seed 不会泄露祖先的描述符）得到受支持的描述符，且会话 header 将调用方标识为直接 parent 时，该 id 才可恢复。
+
+版本化描述符（[descriptor.ts](../../../../packages/subagent/subagent/src/descriptor.ts) 中的 `SUBAGENT_DESCRIPTOR_VERSION`）包含 subagent 提供方名称、已解析的 child `agentOptions.provider` 和 `agentOptions.model`，以及可选的 `persona` 与 `toolFilter`。它不会对可通过声明合并扩展的 `AgentOptions` 对象建立快照：与此无关的扩展值不会仅因无法表示为 JSON 而导致继续执行失败。描述符会特意省略 `subagentDepth`；从持久化存储恢复时，系统依赖持久化 header 中的 `delegationDepth`，而不根据描述符重建深度。`outputSchema` 属于单次激活的结果契约，不属于持久化 child 组合配置。child header 仍是 child id、`cwd`、`parentSession`、`seedLength` 和 `delegationDepth` 的权威信息，持久化 child transcript 则负责保存 fork seed 和后续历史。[`delegationDepthOf()`](../../../../packages/subagent/subagent/src/index.ts) 会在 header 值和运行时值中取最大值，因此重建后的运行时选项可以加深持久化值，但绝不能降低它，恢复后的 child 无法重新获得顶层委派预算。
+
+从持久化存储恢复不能依赖旧 `SubagentRun` 的可选方法，因为该 run 已被 dispose，并且进程重启后不会保留。`SubagentRun` 不含 `resume` 操作：run 表示一次可 dispose 的激活，只暴露作用于当前激活的操作。原有的 `SubagentRun.sendMessage?()` 功能改名为 `SubagentRun.steer?()`，以免其严格的仅在线契约与服务编排或面向模型的工具混淆。
+
+`SubagentControlService` 的恢复路径会加载已知 child 会话、归并其描述符、根据持久化的 `parentSession` 鉴权，并在其创建的 Task 内部运行。它向底层 `SubagentService.resume(provider, request)` 传递完全解析的请求，其中包含由 Task 持有的取消信号；后者只负责检查提供方功能后进行分发，并执行 `start` 所使用的普通 run 生命周期观察。选中的 `SubagentProvider.resume?()` 负责传输相关的重建（进程内：在当前加载的 parent 作用域下执行 `parent.ctx.agents.resume`），并返回一个新 run。提供方是否存在该方法本身就是继续执行功能，无需额外功能标志。`SubagentControlService.sendMessage()` 在关联 run 的 `steer?()` 操作与该持久化恢复路径之间做出选择。底层服务和提供方都不会枚举持久化 child 或关联 Task。
+
+后台工具会在调用 `TaskService.start()` 前校验描述符输入并建立快照。同步校验失败会拒绝工具调用，且不会创建 Task。除此之外，工具会立即返回 child id 和 Task id，不等待 child 发布或描述符持久化完成。child 创建、首轮持久化或描述符持久化失败时，系统会 dispose 所有已发布的 run，并将已经创建的 Task 结算为 `failed`；模型通过普通 Task 完成通知或 `task_output` 路径观察该失败。进程内 spawn 和 fork 会在当前已加载的 parent 作用域下重建组合配置。恢复 fork 时只加载 child 自己的持久化 transcript，其中已经包含初始创建时捕获的已完成轮次前缀；系统绝不会再次 fork parent 更新后的历史。恢复 parent 不会立即恢复其 child。
+
+TODO（ACP 继续执行）：将远端 ACP session id 作为提供方专用描述符数据持久化，并实现 `AcpProvider.resume?()`，依次执行 spawn、initialize、`loadSession` 和 prompt。初始 ACP run 必须检查 `initialize.agentCapabilities.loadSession`，恢复后的每个进程必须使用同一个持久化后端；`loadSession` 回放的历史消息不得计入新激活的输出。由于 ACP 的加载支持是按 child 协商的，不能仅根据提供方是否存在该方法来确定，因此该后续工作还必须定义 start 结果如何声明单个 child 支持继续执行，之后才能将 ACP child 写入持久化目录。
+
+### 结果与通知所有权
+
+每次可继续 child 激活都恰好拥有一个 Task 和一个 `TaskOutcome`，无论第一条消息由 parent 还是用户提供。只要 Task 尚未标记为已报告，通用 Task 报告契约最多会向保留的 parent owner 注入一条主动完成通知；读取、等待和取消都可能抑制该通知。发送到运行中激活的消息会加入该激活，不会创建第二个 Task 或第二份结果。child transcript 是面向用户的详细记录；Task 输出是面向 parent 的最终结果。
+
+Task 记录和活跃 run 关联都位于进程内。持久化使 child 会话可在重启后恢复，但不会恢复中断的 Task、其结果或通知。持久化 Task 恢复属于另一个问题。
+
+## 已考虑的替代方案
+
+**在 Task 结算后保留所有后台 child。** 这是 Codex 风格的常驻会话模型：发送后续消息成本较低，但历史 child 会持续占用 agent 作用域、会话内存、监听器和提供方资源，直至显式常驻数量上限或淘汰策略将其移除。逐激活 dispose 使用持久化作为继续执行边界，同时保留当前的资源上限。
+
+**允许用户轮次不使用 Task。** parent 消息加入此类轮次后，没有对应的 Task 结果或完成通知；UI 取消对 parent 所发消息的影响也不明确。让每次激活都拥有一个 Task，可使完成与取消成为 child 轮次的属性，而不是初始调用方的属性。
+
+**在 child 会话整个生命周期内复用一个 Task。** 终态 Task 无法自然地再次进入运行状态，一个结果也无法表示多个轮次。每次激活创建新 Task 可以保留通用 Task 契约。
+
+**为每条消息创建 Task。** 发送到现有 run 的消息会加入已有轮次，不产生独立的最终结果；为这类消息创建 Task，会重复当前 Task，或报告一个它并不拥有的结果。只有启动新激活的消息才会创建 Task。
+
+**拆分 `send_message` 与 `follow_up`。** 两个严格操作会向模型暴露实现状态差异，却无法消除 child 已停止时的竞态。单一操作采用 Claude Code 模型：向运行中的工作发送消息，或恢复一个由新 Task 支撑的生命周期。
+
+**在已 dispose 的 run 上保留 `resume?()`。** 如果仅为调用 `resume()` 而保留已 dispose 的 `SubagentRun`，旧 run 会同时充当持久化 child handle，而且进程重启后无法重建该对象。由服务分发、提供方重建，可明确表达持久化边界。
+
+**将控制编排放在 `SubagentService` 上。** 这样一个服务就能查找描述符、关联 Task 并分发提供方，但会迫使不感知集合的提供方 seam 依赖某个消费方的持久化与 Task 策略。单独的控制服务让前台及不使用 Task 的消费方可以复用 start／resume 传输，同时为工具和 UI 提供统一的编排路径。
+
+**增加显式激活阶段。** 公开的 `starting`／`running`／`settling` 状态可以准确描述准入和清理，但会引入实现本身并不需要的生命周期协议。同步安装关联无需暴露这些阶段，即可消除进程内重复的 cold resume。

+- `packages/subagent/subagent-control/tests/subagent-control.spec.ts` 以无密钥方式驱动真实栈（agent loop、JSONL 持久化、spawn／fork 提供方、Task 服务与控制面、控制服务）：初始及恢复后的激活都会创建新 Task，并在进入终态前 dispose 各自的 run；描述符事件位于轮次内、对模型隐藏、带版本，并在控制服务分配的 child id 下持久化；在 run 运行期间或 cold resume 查找期间执行 `task_kill`，会在完全停稳后结算为 `killed`，且不产生任何 child 工作；steering 会加入运行中的 Task，而不创建第二个 Task；cold follow-up 会在一份持久化 transcript 中累积轮次，并重建声明的组合配置；恢复 fork 会保持持久化 seed 边界，绝不重新 fork parent 更新后的历史；恢复后的深度以持久化 header 为下界；外来 parent、无描述符及 unmaterialized 的 id 会带着「id 不可用」使其已启动的 Task 失败；所有权冲突和 steering 与结算的竞态会报告未送达，且不改用从持久化存储恢复路径；resume 加载期间竞争的发送只准入一次。
+- `packages/subagent/tool-subagent-control/tests/tool-subagent-control.spec.ts` 固定 `send_message` 的 schema、两种路由渲染、未送达失败、无 agent 时的拒绝，以及 HMR（热模块替换）dispose。
+- `packages/subagent/tool-subagent/tests/tool-subagent.spec.ts` 覆盖按功能分支的后台路由：可恢复的提供方会通过控制服务返回两个 id 并公开 `send_message`，一次性提供方保持普通的 task 确认消息，而缺少控制服务的可恢复提供方会明确失败。
+- 无密钥 ACP 快照场景 `subagent-continuable`（examples/acp-agent）固定模型可见的 transcript：双 id 确认消息、`task_output` 结果收集，以及一次 `send_message` 后续操作——其已启动的 Task 会带着「id 不可用」失败。
+
+## 影响
+
+- 每次完成结算后的后续轮次都需要承担持久化加载和作用域 setup 成本；作为交换，存活 child 的数量受并发工作量限制，而不是随历史会话数量增长。持久化不可用或存储的组合配置无法重建时，可继续 child 的创建会明确失败。
+- 两个调用方仍可能通过控制服务外部的路径争抢已停止的 child。Agent 注册表会阻止相同会话的重复发布；失败的 Task 会失败，且其消息不会送达。消息也可能与取消、终态状态发布或 run dispose 发生竞态。准入不承诺原子或恰好执行一次；在进程内同步安装的关联无需公开生命周期状态机，即可通过控制服务消除重复的 cold resume。
+- 通过普通 Agent API 驱动可继续 child 会绕过其 Task 关联。控制服务会将该存活 child 视为所有权冲突并拒绝；适配器必须在不加载 Agent 的情况下展示持久化 transcript，并通过 `SubagentControlService.sendMessage()` 提交用户输入。
+- 活跃 run 关联只能协调一个运行时。多个进程同时恢复时不会串行化；此类部署需要持久化层的租约或 compare-and-set 操作。
+- 用户交互要求作为 owner 的那个精确 parent Agent 实例保持存活，因为 dispose owner 会取消并移除其 Task。用户交互还要求附加 Task 控制面。若要单独与 child 交互，后续必须将 Task 访问所有权与持久化通知目标分离。
+- 后台工具会在 child 发布和描述符持久化之前返回 child id 和 Task id。启动失败、持久化失败，或进程在 child 首次 flush 之前退出，都可能留下 unmaterialized child id；按 id 的控制操作会报告该 id 不可用，持久化枚举也不会列出它，而不会追溯修改工具返回结果。
+- 将显式组合字段持久化到 child 日志后，其无损 JSON 与兼容性契约便成为恢复契约的一部分。后续如需支持其他组合配置输入，必须明确更改描述符版本，不能隐式持久化可通过声明合并扩展的 `AgentOptions` 字段。
+- Task 记录和活跃 run 关联位于进程内，而 child 会话具有持久性。重启会恢复会话，但不会恢复进行中的工作或其 Task 通知。

-# Agent Note: Continuable background subagents
-
-Status: proposed
-
-English | [中文](2026-07-21-continuable-background-subagents.zh.md)
-
-## Problem
-
-The subagent tool treats each delegation as one owned `SubagentRun`: foreground calls and background Tasks collect the result and then dispose the run. Disposal bounds the number of live child Agents and releases their scoped services, listeners, and provider resources. The persisted child session may survive, but the parent has no durable catalog or tool path for discovering that child and starting another turn on it.
-
-A Task, a run, and a child session have different lifetimes. A Task represents one background turn and has one terminal result. A `SubagentRun` owns one activation of a child. A persisted child session may contain many turns initiated by the parent or a human. Continuation must preserve per-run disposal rather than retain every historical child Agent in memory.
-
-## Proposal
-
-A continuable background subagent is a durable child session with a series of Task-backed activations. The child session id, transcript, lineage, and declared composition survive in persistence. Each initial or resumed activation creates a fresh Task, `AgentHandle`, and `SubagentRun`, drives one turn, collects its result, and disposes the run before the Task becomes terminal.
-
-The Task's result and cancellation boundary belong to the child activation, not to whichever caller supplied its first message. Task access is authorized by the parent session id, while the Task registry retains the exact live parent Agent instance for notification and teardown. Parent and human messages therefore share one activation result while the parent remains its runtime owner:
-
-```text
-durable child Session
-  activation 1: Task 1 -> SubagentRun -> AgentHandle -> dispose
-  activation 2: Task 2 -> SubagentRun -> AgentHandle -> dispose
-  activation 3: Task 3 -> SubagentRun -> AgentHandle -> dispose
-```
-
-Foreground delegation keeps its current one-shot behavior. The first continuable implementation covers background in-process spawn and fork children. A provider must support persisted cold resume before its children are advertised as continuable; ACP children remain one-shot until the deferred ACP continuation work below is complete.
-
-The low-level `ctx.subagents` seam remains collection-, Task-, and persistence-agnostic. It registers providers, validates and dispatches `start` or `resume`, observes run lifecycle, and returns holder-owned runs. A separate `SubagentControlService` in `@deepseek-ai/dsh-subagent-control` owns stable continuable-child ids, descriptor persistence and lookup by known child id, Task-backed activation, and message routing. The provider-bound `@deepseek-ai/dsh-tool-subagent` plugin and human-facing adapters call that control service for continuable background work; foreground one-shot delegation still calls `ctx.subagents.start()` directly. The globally named model tool is a thin adapter in `@deepseek-ai/dsh-tool-subagent-control`. Parent-to-child enumeration and `list_agents` belong to a separate durable-catalog proposal.
-
-### Task and cancellation ownership
-
-The initial background delegation asks the control service to start the child and register its Task. Task settlement awaits the result, calls `run.dispose()`, and only then records the `TaskOutcome`; `task_kill` aborts the active run, whose settlement path still disposes it. A terminal Task therefore leaves the durable child session but no live child Agent.
-
-Every later turn creates another Task. Its producer resources cover only that activation, never the child session. It reaches one terminal status, has one result, and is never reopened. The exact live parent Agent remains the Task registry owner: disposing that instance cancels, awaits, and removes its Tasks. Task APIs authorize a caller whose session id matches that owner, but a same-id replacement does not become the notification or teardown target. This preserves the existing `settleRun()` contract and bounds Task-owned live children by concurrent work rather than historical session count.
-
-Opening a child session in a human-facing adapter reads its persisted transcript and does not resume an Agent merely to display it. Human input starts or joins the same Task-backed activation used by parent input through the control service. A human-started Task retains the exact currently loaded parent Agent as its notification target, and `task_output` remains the single result path. The existing completion listener injects at most one unsolicited notice while the Task is unreported; `kill`, a terminal read, or a terminal wait may mark it reported and suppress that notice. The first version therefore permits human interaction only while that parent instance remains live. A user-owned conversation that may outlive the parent and explicitly merge a conclusion back belongs to [interactive side sessions](2026-07-08-interactive-side-sessions.md), not this Task-owned lifecycle.
-
-`TaskService.start()` rejects producers when no Task control surface is attached. A human-facing adapter that accepts child input must therefore attach a Task control surface, or run in a deployment that loads `@deepseek-ai/dsh-tool-tasks`; loading the Task service alone is insufficient. This dependency is the cost of using the same Task result, cancellation, and notification path for parent- and human-started activations.
-
-Cancellation always targets the whole current activation. If human and parent messages have joined one turn, either caller's cancellation aborts that turn, disposes its run, and settles its Task as `killed`; the messages do not have independent results or cancellation rights. Independent cancellation requires a later message to start a separate turn instead of steering the current one.
-
-A cold-resume Task creates its activation-owned `AbortController` before descriptor lookup or any provider await and passes that signal through `SubagentControlService.resume()`, `SubagentService.resume()`, and `SubagentProvider.resume?()`. A persistence call that has no signal need not stop its underlying I/O, but the control service rechecks cancellation after every such await and cannot begin or publish child work afterward. Before Agent publication, abort makes the provider reject only after its creation transaction has rolled back and reached quiescence. After publication, the provider closes the creation-signal handoff race, attaches the same signal to the live run before returning it, and cancellation stops the child turn. `task_kill` and exact-owner disposal use this path even when provider resume has not returned a `SubagentRun`; Task settlement waits for rollback or run disposal and records `killed` only after the activation is quiescent.
-
-### Active run association
-
-The control service keeps a process-local association from child session id to its current Task and, after provider publication, its run. It installs the Task association before awaiting provider start or resume, fills in the returned run, and removes the association only after run disposal and Task terminal publication. This association exists only so parent and human senders can find the same activation; it is not a durable catalog, public `ManagedSubagent`, admission reservation, or run-state machine.
-
-For a continuable initial activation, the control service allocates the stable child session id before Task creation and passes it in the resolved provider start request; in-process spawn and fork publish that exact id instead of allocating one internally. The background tool acknowledgement exposes both identities as `started subagent  as task `. The child id names the durable conversation across activations, while the Task id names only the current activation. A failed initial Task or a process exit before the first child flush can leave an **unmaterialized child**: the caller holds a child id without a durable header and descriptor. Later by-id control operations report that id as unavailable, and durable enumeration omits it.
-
-The first version admits every continuable child turn through this Task-backed path. A non-terminal Task is the only supported live activation; when no activation exists, its run has already been disposed and the durable child is resumable. Before routing any by-id operation, the control service synchronously compares its association with `ctx.agents.get(childId)`. A registry Agent with no association, or a registry Agent different from the associated `run.localAgent`, is an ownership conflict: the control service fails rather than adopting an idle Agent or attaching an untracked turn. When neither exists, cold resume may proceed; a competing publication after that check still loses at the Agent registry collision boundary.
-
-Routing follows the Task association. A running Task accepts live delivery through the run's optional strict `SubagentRun.steer` capability. An absent Task starts a fresh Task and cold-resumes the child. In-process spawn and fork implement this capability by synchronously requiring `AgentStatus.running` before calling `Agent.steer()`; the check and call contain no asynchronous boundary. Providers must not expose the Agent-level idle fallback as strict steering, because that fallback may start an untracked turn after the observed run has ended. If the Task settles between association lookup and this strict check, `steer()` fails, `send_message` reports the message as not delivered, and that call does not fall through to cold resume; a later retry after Task terminal may start the next activation.
-
-The first version does not serialize two callers that concurrently observe a stopped child, nor does it model a separate settling phase between result production and disposal. Concurrent cold-resume attempts may both create Tasks, but the Agent registry permits only one same-session Agent to publish; a losing Task fails and its message is not delivered. Delivery racing startup, cancellation, completion, or cleanup may also fail. These limitations are explicit rather than hidden behind a larger lifecycle abstraction.
-
-Atomic process-local admission is on hold. The smallest follow-up would synchronously reserve the child before awaiting resume, conceptually with `Map>`; later callers would await the same publication promise and then use strict live delivery. This would close duplicate cold resume without adding a public `ManagedSubagent` or explicit `starting`/`running`/`settling` protocol.
-
-### Model-facing `send_message`
-
-The model receives one `send_message(subagent_id, message)` tool backed by `SubagentControlService.sendMessage()`. The control operation owns steer-or-resume orchestration and is distinct from the run's `SubagentRun.steer?()`, which only delivers to an already active run. The tool performs no lifecycle routing of its own. It lives in a separately loaded `@deepseek-ai/dsh-tool-subagent-control` package so provider-bound `@deepseek-ai/dsh-tool-subagent` instances can continue registering distinct delegation tools for spawn, fork, or ACP without registering duplicate global control tools.
-
-- If the child has a running Task and live-steering capability, the service calls `run.steer(message)` and returns the existing Task id; it creates no Task of its own.
-- If the child has no running Task, `send_message` creates a fresh Task, cold-resumes the durable session with the message, and returns the new Task id.
-- If the active provider cannot accept live delivery, strict steering loses a race with Task settlement, or a live child exists outside the Task association, `send_message` fails rather than silently starting, resuming, or adopting an untracked turn.
-
-The service result identifies the route as `steered` with the existing Task id or `started` with the new Task id. Failure is explicit and says that the message was not delivered. The model-facing tool renders these distinctions so timing-dependent routing is observable to the caller.
-
-A delivered message has no independent result: its effect is reflected in the current Task's eventual result. A started follow-up has the fresh Task's result and existing `task_output` read path. The subagent layer adds no second completion injection.
-
-Human input uses the same control operation. The UI may display the child transcript and current Task state, while cancellation calls the Task service with the loaded parent as caller. Tool schema and UI adapters are consumers of one control-service contract rather than separate execution paths.
-
-### Durable child handle and cold resume
-
-The control service snapshots every descriptor input with [`snapshotJsonValue`](../../../../packages/core/session/src/json.ts) before Task creation, matching the detached lossless-JSON boundary already used by Agent messages. A child-scoped setup contribution appends one model-hidden `subagent/descriptor` event after the initial child `turn/start` and before its first request; it carries no `surfaceOp`, remains outside model history, and reaches persistence with that turn's flush. The append-only log retains this non-surface event when compaction replaces surface history. A known child id is resumable only when loading that child session yields a supported descriptor and its header identifies the caller as the direct parent.
-
-The versioned descriptor contains the subagent provider name, resolved child `agentOptions.provider` and `agentOptions.model`, and optional `persona` and `toolFilter`. It does not snapshot the merge-extensible `AgentOptions` object: unrelated extension values cannot make continuation fail merely because they are not JSON. It deliberately omits `subagentDepth`; cold resume relies on the persisted header's `delegationDepth` rather than reconstructing depth from the descriptor. `outputSchema` belongs to one activation's result contract rather than durable child composition. The child header remains authoritative for the child id, `cwd`, `parentSession`, `seedLength`, and `delegationDepth`, while the persisted child transcript owns the fork seed and subsequent history. [`delegationDepthOf()`](../../../../packages/subagent/subagent/src/index.ts) takes the maximum of header and runtime values, so reconstructed runtime options may deepen the persisted value but never lower it and a resumed child cannot regain a top-level delegation budget.
-
-Cold resume cannot depend on an optional method of the old `SubagentRun`, because that run has been disposed and is not retained across process restart. This proposal removes `SubagentRun.resume?()`: a run represents one disposable activation and exposes only activation-scoped operations. It also renames the existing `SubagentRun.sendMessage?()` capability to `SubagentRun.steer?()` so its strict live-only contract cannot be confused with service orchestration or the model-facing tool.
-
-`SubagentControlService.resume()` loads the known child session, folds its descriptor, authorizes the persisted `parentSession`, and creates the Task. It passes a fully resolved request, including the Task-owned cancellation signal, to the low-level `SubagentService.resume(provider, request)`, whose only responsibility is capability-checked provider dispatch and the ordinary run lifecycle observation used by `start`. The selected `SubagentProvider.resume?()` owns transport-specific reconstruction and returns a fresh run. Presence of the provider method is the continuation capability, so no redundant capability flag is added. `SubagentControlService.sendMessage()` chooses between the associated run's `steer?()` operation and this cold-resume path. Neither the low-level service nor a provider enumerates durable children or associates Tasks.
-
-The background tool validates and snapshots descriptor inputs before calling `TaskService.start()`. A synchronous validation failure rejects the tool call and creates no Task. The tool otherwise returns the child and Task ids immediately, without waiting for child publication or descriptor durability. Child creation, first-turn persistence, or descriptor persistence failure disposes any published run and settles the already-created Task as `failed`; the model observes that failure through the ordinary Task completion or `task_output` path. The first implementation reconstructs in-process spawn and fork composition under the currently loaded parent scope. A fork resume loads the child's own persisted transcript, which already contains the completed-turn prefix captured at initial creation; it never forks the parent's newer history again. Resuming a parent does not eagerly resume its children.
-
-TODO (ACP continuation): persist the remote ACP session id as provider-specific descriptor data and implement `AcpProvider.resume?()` as spawn, initialize, `loadSession`, then prompt. The initial ACP run must verify `initialize.agentCapabilities.loadSession`, and every resumed process must use the same durable backend; replayed history from `loadSession` must not be collected as the new activation's output. Because ACP load support is negotiated per child rather than established solely by the provider method's presence, this follow-up must also define how a start result advertises child-specific continuation before ACP children enter the durable catalog.
-
-### Result and notification ownership
-
-Every continuable child activation has exactly one Task and one `TaskOutcome`, regardless of whether the parent or a human supplied the first message. The generic Task reporting contract may inject at most one unsolicited completion notice to the retained parent owner while the Task is unreported; reads, waits, and cancellation may suppress it. Running delivery joins that activation and creates neither a second Task nor a second result. The child transcript remains the human-facing detailed record; Task output remains the parent-facing final result.
-
-Task records and active-run associations are process-local. Persistence makes the child session resumable after restart, but does not recover an interrupted Task, its result, or its notification. Durable Task recovery is a separate concern.
-
-### Implementation boundary
-
-One implementation PR delivers this proposal: stable child-id allocation and provider handoff, the child-session descriptor event, `SubagentControlService`, in-process provider cold resume, existing background-delegation routing, strict spawn/fork steering, active-run association, human message routing, and the separately loaded `@deepseek-ai/dsh-tool-subagent-control` package with its `send_message` tool. Parent-to-child enumeration and `list_agents` consume this durable child-handle contract but remain a separate feature and PR. ACP continuation is a separate provider follow-up after the child-specific advertisement contract above is resolved.
-
-## Alternatives considered
-
-**Retain every background child after Task settlement.** This is the Codex-style resident-session model: follow-up delivery is cheap, but historical children retain Agent scopes, session memory, listeners, and provider resources until an explicit residency limit or eviction policy removes them. Per-activation disposal uses persistence as the continuation boundary and preserves the current resource bound.
-
-**Let human turns run without Tasks.** A parent message joining such a turn has no Task result or completion notice, and UI cancellation has unclear effects on the parent's contribution. Giving every activation one Task makes completion and cancellation properties of the child turn rather than its initiating caller.
-
-**Keep one Task for the lifetime of a child session.** A terminal Task cannot naturally become running again, and one result cannot represent multiple turns. Fresh activation-scoped Tasks preserve the generic Task contract.
-
-**Create a Task for every message.** Steering joins an existing turn and has no independent final result, so a Task created for steering would duplicate the active Task or report a result it does not own. Only a message that starts an activation creates a Task.
-
-**Split `send_message` and `follow_up`.** Separate strict operations expose an implementation-state distinction to the model without removing stopped-child races. One operation follows the Claude Code model: deliver to running work or resume a new Task-backed lifecycle.
-
-**Keep `resume?()` on the disposed run.** Retaining a disposed `SubagentRun` only to call `resume()` makes the old run double as a durable child handle and cannot reconstruct that object after restart. Service dispatch plus provider reconstruction makes the persistence boundary explicit.
-
-**Put control orchestration on `SubagentService`.** This would let one service look up descriptors, associate Tasks, and dispatch providers, but would make the collection-agnostic provider seam depend on one consumer's persistence and Task policy. A separate control service keeps start/resume transport reusable by foreground and non-Task consumers while giving tools and UI one orchestration path.
-
-**Add explicit activation phases.** Public `starting`/`running`/`settling` states could describe admission and cleanup precisely, but would add a lifecycle protocol that the first implementation does not otherwise need. The on-hold promise reservation closes duplicate process-local cold resume without exposing those phases.
-
-## Acceptance criteria
-
-- Initial and resumed continuable activations create a fresh Task and dispose their run before that Task becomes terminal.
-- Opening a persisted child for display creates no Agent activation; human input under a loaded parent starts or joins a Task-backed activation.
-- Human and parent messages delivered to one running activation share its Task result and cancellation outcome.
-- Cancelling a human-started activation aborts and disposes its run and settles the Task as `killed`; its completion notice follows the generic at-most-one reporting contract and may be suppressed when the Task is already reported.
-- A cold-resume Task owns its AbortSignal before descriptor lookup; cancellation during lookup or provider resume prevents later publication or cancels the published run, and Task settlement waits for rollback or disposal quiescence before reporting `killed`.
-- A human-facing adapter attaches a Task control surface before accepting child input; absence of a surface fails clearly instead of starting untracked work.
-- `send_message` delivers to a running child without creating a Task and cold-resumes a stopped child into a fresh Task-backed activation.
-- `send_message` reports whether it `steered` an existing Task or `started` a new Task, including the relevant Task id, and reports a failure as not delivered.
-- Initial continuable delegation allocates its child id before Task creation, passes that id through provider publication, and returns both the stable child id and activation Task id to the model.
-- Spawn and fork implement strict `SubagentRun.steer` behavior with no asynchronous boundary between the running check and `Agent.steer()`; live delivery cannot fall back to an untracked Agent turn.
-- If strict steering loses a race with Task settlement, `send_message` reports the message as not delivered and does not cold-resume within that call.
-- `SubagentRun` has no cold-resume operation; `SubagentControlService.sendMessage()` dispatches active delivery to `run.steer?()` and inactive delivery through low-level `SubagentService.resume()` to `SubagentProvider.resume?()`.
-- The `SubagentRun.sendMessage?()` to `steer?()` rename and the background activation route update the seam module JSDoc, package READMEs, core-data-structures catalog, and `tool-subagent` `settleRun` ownership documentation and tests in the same PR.
-- `SubagentService` remains unaware of Tasks and durable descriptors; `SubagentControlService` owns continuable activation, authorization, descriptor lookup by known child id, and Task/run association for tool and UI consumers.
-- Every supported continuable child turn installs its Task association before provider awaits and retains it through run disposal; by-id routing rejects a live `ctx.agents.get(childId)` unless the association exists and its `run.localAgent` is that exact Agent.
-- A known persisted child id can be authorized and lazily reconstructed after parent resume with equivalent declared composition under the resumed parent's scope; fork resume uses only the child's persisted transcript and never re-forks current parent history.
-- Descriptor inputs are snapshotted before Task creation; a versioned model-hidden descriptor event is turn-enclosed in the child session, excluded from the surface, retained across compaction, and folded only after the child header passes direct-parent authorization. The descriptor omits `subagentDepth`, and resumed depth uses the persisted header as its monotone floor.
-- Invalid descriptor JSON rejects the tool without creating a Task, while asynchronous child or descriptor persistence failure disposes the run and settles the returned Task as `failed`.
-- Provider-bound delegation tools remain in `@deepseek-ai/dsh-tool-subagent`; the globally named `send_message` tool registers once from `@deepseek-ai/dsh-tool-subagent-control`.
-- Each activation produces one Task result and at most one unsolicited existing Task completion notice; reads, waits, or cancellation may suppress that notice, and steering and the subagent layer add no duplicate notification.
-- Tests document that concurrent stopped-child admission is not atomic: one same-session publication wins, a losing Task fails, and the losing message is not reported as delivered.
-- Keyless package tests cover Task ownership, disposal ordering, human start and cancellation, running delivery, cold follow-up, descriptor rejection and rollback, known-id reconstruction, scope reconstruction, and terminal cleanup. Model-visible tool and transcript changes have runnable snapshot coverage.
-
-## Risks
-
-- Every follow-up after settlement pays persistence load and scoped setup cost. Continuable creation fails clearly when persistence is unavailable or the stored composition cannot be reconstructed.
-- Two callers may concurrently observe a stopped child and start competing resumes. The Agent registry prevents duplicate same-session publication, but a losing Task fails and its message is not delivered. A message may also race cancellation, terminal status publication, or run disposal. The first version does not claim atomic or exactly-once admission; the on-hold process-local promise reservation can close duplicate cold resume without requiring a public lifecycle state machine.
-- Driving a continuable child through the ordinary Agent API bypasses its Task association. The control service rejects that live child as an ownership conflict; adapters must display persisted transcripts without loading an Agent and submit human input through `SubagentControlService.sendMessage()`.
-- The active-run association coordinates only one runtime. Concurrent resume from multiple processes is not serialized; that deployment requires a persistence-level lease or compare-and-set operation.
-- Human interaction requires the exact parent Agent instance to remain live because owner disposal cancels and removes its Tasks. It also requires an attached Task control surface. Standalone child interaction requires a future separation between Task access ownership and durable notification targeting.
-- The background tool returns child and Task ids before child publication and descriptor durability. Startup failure, persistence failure, or process exit before the first child flush may leave an unmaterialized child id; by-id control reports it as unavailable and durable enumeration omits it rather than retroactively changing the tool result.
-- Persisting explicit composition fields in the child log makes their lossless-JSON and compatibility contract part of resume. Later support for another composition input requires a deliberate descriptor-version change rather than implicitly persisting merge-extensible `AgentOptions` fields.
-- Task records and active-run associations are process-local even though child sessions are durable. Restart recovers the session, not in-flight work or its Task notification.

-# Agent Note: 可继续的后台 subagent
-
-Status: proposed
-
-[English](2026-07-21-continuable-background-subagents.md) | 中文
-
-## 问题
-
-subagent 工具将每次委派视为一个独占的 `SubagentRun`：前台调用和后台 Task 收集结果后 dispose（资源释放）该 run。这种所有权关系能够限制存活 child agent（智能体）的数量，并释放其作用域服务、监听器及提供方资源。持久化的 child 会话可能继续存在，但 parent 缺少持久化目录和工具路径，无法发现该 child 并为其启动另一轮次。
-
-Task、run 和 child 会话具有不同的生命周期。一个 Task 表示一轮后台执行，并且只有一个终态结果。一个 `SubagentRun` 拥有 child 的一次激活。一个持久化 child 会话可以包含多个由 parent 或用户发起的轮次。继续执行必须保留逐 run dispose 的约定，而不能把所有历史 child agent 都留在内存中。
-
-## 提案
-
-一个可继续的后台 subagent，是由一系列 Task 支撑的短期激活共同组成的持久化 child 会话。child session id、transcript（文本记录）、谱系及声明的组合配置均保留在持久化存储中。每次初始激活或恢复激活都会创建新的 Task、`AgentHandle` 和 `SubagentRun`，驱动一个轮次、收集结果，并在 Task 进入终态前 dispose 该 run。
-
-Task 的结果和取消边界属于 child 激活，不属于为该激活提供第一条消息的调用方。Task 访问根据 parent session id 授权，而 Task 注册表仍保留当前存活的精确 parent Agent 实例，用于通知与资源清理。因此，只要 parent 仍是运行时 owner，parent 消息和用户消息便会共享同一个激活结果：
-
-```text
-durable child Session
-  activation 1: Task 1 -> SubagentRun -> AgentHandle -> dispose
-  activation 2: Task 2 -> SubagentRun -> AgentHandle -> dispose
-  activation 3: Task 3 -> SubagentRun -> AgentHandle -> dispose
-```
-
-前台委派保持当前的一次性行为。第一版可继续实现覆盖进程内 spawn 和 fork child。提供方只有支持从持久化存储恢复后，才能将其 child 标记为可继续；在下述 ACP（Agent Client Protocol）后续工作完成前，ACP child 仍保持一次性行为。
-
-底层 `ctx.subagents` seam 不感知 child 集合、Task 与持久化。它注册提供方，校验并分发 `start` 或 `resume`，观察 run 生命周期，并返回由持有方负责的 run。`@deepseek-ai/dsh-subagent-control` 中单独的 `SubagentControlService` 负责管理可继续 child 的稳定 id、持久化描述符并按已知 child id 查找、由 Task 支撑的激活，以及消息路由。按提供方绑定的 `@deepseek-ai/dsh-tool-subagent` 插件及面向用户的适配器通过该控制服务处理可继续后台工作；前台一次性委派仍直接调用 `ctx.subagents.start()`。全局命名的模型工具是 `@deepseek-ai/dsh-tool-subagent-control` 中的轻量适配器。parent 到 child 的枚举与 `list_agents` 属于单独的持久化目录提案。
-
-### Task 与取消的所有权
-
-初始后台委派请求控制服务启动 child 并注册其 Task。Task 结算流程等待结果，调用 `run.dispose()`，然后才记录 `TaskOutcome`；`task_kill` 中止活跃 run，其结算路径仍会 dispose 该 run。因此，终态 Task 会留下持久化 child 会话，但不会留下存活的 child agent。
-
-后续每个轮次都会创建另一个 Task。该轮 producer 持有的执行资源仅服务于这次激活，不属于 child 会话。它只会到达一次终态、只产生一个结果，也不会重新打开。Task 注册表中当前注册的那个存活 parent agent 实例仍是其 owner：dispose 该实例会取消、等待并移除其 Task。Task API 会授权 session id 与该 owner 匹配的调用方，但 id 相同的替代实例不会成为通知或资源清理目标。这一设计保留现有 `settleRun()` 契约，并使 Task 所拥有的存活 child 数量受并发工作量限制，而不是随历史会话数量增长。
-
-用户界面适配器打开 child 会话时，只读取持久化 transcript，不会仅为展示而恢复 agent。用户输入通过控制服务，启动或加入与 parent 输入相同的 Task 激活。由用户启动的 Task 会保留当前加载的精确 parent Agent 作为通知目标，`task_output` 仍是唯一结果路径。只要 Task 尚未标记为已报告，现有完成监听器最多注入一条主动通知；`kill`、终态读取或终态等待都可能将其标记为已报告，并抑制这条通知。第一版仅允许在该 parent 实例保持存活时进行用户交互。可以比 parent 存活更久、并将结论显式合并回去的用户自有会话属于[交互式 side session](2026-07-08-interactive-side-sessions.md)，不属于这一由 Task 持有的生命周期。
-
-如果没有附加 Task 控制面，`TaskService.start()` 会拒绝 producer。因此，接受 child 输入的用户界面适配器必须附加 Task 控制面，或运行于加载了 `@deepseek-ai/dsh-tool-tasks` 的部署中；仅加载 Task 服务并不足够。这项依赖是 parent 和用户启动的激活共用 Task 结果、取消和通知路径所付出的代价。
-
-取消始终作用于当前完整激活。如果用户消息和 parent 消息已经加入同一个轮次，任一调用方发起取消都会中止该轮次、dispose 其 run，并将对应 Task 结算为 `killed`；这些消息没有独立的结果或取消权。若需要独立取消，后续消息必须另起轮次，而不能加入当前轮次。
-
-从持久化存储恢复的 Task 会在查找描述符或等待任何提供方操作之前，创建由本次激活持有的 `AbortController`，并通过 `SubagentControlService.resume()`、`SubagentService.resume()` 和 `SubagentProvider.resume?()` 逐层传递其信号。对于不接受信号的持久化调用，可以让底层 I/O 执行完毕；但控制服务必须在每次这类 await 返回后重新检查取消状态，如已取消，之后不得开始或发布任何 child 工作。在 Agent 发布前收到中止信号时，提供方必须先回滚其创建事务并达到完全停稳状态，然后才让恢复调用以拒绝结束。Agent 发布后，提供方必须消除创建期间移交取消信号时的竞态，在返回前将同一信号附加到存活 run；之后取消会停止 child 轮次。即使提供方的恢复调用尚未返回 `SubagentRun`，`task_kill` 与对确切 owner 实例的 dispose 仍通过这条路径生效。Task 结算会等待回滚或 run dispose 完成，只有在激活完全停稳后才记录 `killed`。
-
-### 活跃 run 关联
-
-控制服务在进程内维护 child session id 到当前 Task 的关联，并在提供方发布后将 run 填入该关联。它会在等待提供方 start 或 resume 之前安装 Task 关联，填入返回的 run，并且只在 run dispose 完成且 Task 终态发布后才移除该关联。该关联只用于让 parent 发送方和用户发送方找到同一次激活；它不是持久化 child 目录、公开的 `ManagedSubagent`、准入预留或 run 状态机。
-
-对于可继续 child 的初始激活，控制服务会在创建 Task 前分配稳定的 child session id，并通过已完全解析的提供方启动请求传递该 id；进程内 spawn 和 fork 会发布这一确切 id，而不是在内部另行分配。后台工具的确认消息会同时公开两种标识，格式为 `started subagent  as task `。child id 在多次激活中始终指代同一个持久化对话，Task id 则只指代当前激活。初始 Task 失败，或进程在 child 首次 flush 之前退出，都可能留下一个 **unmaterialized child**：调用方持有 child id，但不存在持久化 header 和描述符。后续按 id 的控制操作会报告该 id 不可用，持久化枚举也不会列出它。
-
-第一版要求每个可继续 child 轮次都通过这条由 Task 支撑的路径准入。非终态 Task 是唯一受支持的存活激活；不存在激活时，其 run 已被 dispose，持久化 child 可以恢复。在路由任何按 id 的操作之前，控制服务会同步将自身关联与 `ctx.agents.get(childId)` 比较。如果注册表中的 Agent 没有关联，或者它与所关联的 `run.localAgent` 不同，就属于所有权冲突：控制服务会失败，而不会接管 idle Agent 或附加未受跟踪的轮次。二者均不存在时，可以从持久化存储恢复；如果检查后又有竞争方发布，仍会在 Agent 注册表的冲突边界上失败。
-
-系统依据 Task 关联进行路由。运行中的 Task 通过 run 可选且严格的 `SubagentRun.steer` 功能接收在线消息。Task 不存在时，系统创建新 Task，并从持久化存储恢复 child。进程内 spawn 和 fork 通过以下方式实现该功能：调用 `Agent.steer()` 前同步要求 `AgentStatus.running`，检查与调用之间不存在异步边界。提供方不得将 Agent 层的 idle fallback 暴露为严格 steering（中途引导），因为观察到的 run 结束后，该 fallback 可能启动一个未受 Task 跟踪的轮次。如果 Task 在查找关联与执行这项严格检查之间进入结算，`steer()` 会失败，`send_message` 会报告消息未送达，而且该次调用不会改用从持久化存储恢复路径；在 Task 终态发布后重试，才可能启动下一次激活。
-
-第一版不会串行化两个同时观察到 child 已停止的调用方，也不会为结果产生与 dispose 之间的阶段单独建立 settling 状态。并发的 cold resume 尝试可能都会创建 Task，但 agent 注册表只允许一个相同会话的 agent 完成发布；失败的 Task 不会送达其消息。发送也可能因与启动、取消、完成或清理发生竞态而失败。本提案明确接受这些限制，不为此引入更大的生命周期抽象。
-
-原子的进程内准入暂缓实现。最小的后续方案是在等待 resume 之前同步预留 child，概念上使用 `Map>`；后续调用方等待同一个发布 promise，再使用严格的在线消息功能。这样无需添加公开的 `ManagedSubagent` 或显式 `starting`／`running`／`settling` 协议，即可消除重复的 cold resume。
-
-### 面向模型的 `send_message`
-
-模型获得一个由 `SubagentControlService.sendMessage()` 支撑的 `send_message(subagent_id, message)` 工具。控制操作负责在 steering 与恢复之间编排；它不同于 run 的 `SubagentRun.steer?()`，后者只能向已活跃的 run 发送消息。工具本身不执行生命周期路由。该工具位于单独加载的 `@deepseek-ai/dsh-tool-subagent-control` 包中，因此按提供方绑定的 `@deepseek-ai/dsh-tool-subagent` 实例可以继续为 spawn、fork 或 ACP 注册不同的委派工具，而不会重复注册全局控制工具。
-
-- 如果 child 存在运行中的 Task 并支持在线消息，服务会调用 `run.steer(message)` 并返回现有 task id；它不会创建新 Task。
-- 如果 child 没有运行中的 Task，`send_message` 会创建新 Task，使用该消息从持久化存储恢复会话，并返回新的 task id。
-- 如果活跃提供方无法接收在线消息、严格 steering 在与 Task 结算的竞态中失败，或 Task 关联之外存在存活 child，`send_message` 会失败，而不会静默启动、恢复或接管未受跟踪的轮次。
-
-服务结果将路由标识为 `steered` 并携带现有 task id，或标识为 `started` 并携带新的 task id。失败结果会明确说明消息未送达。面向模型的工具会呈现这些差异，让调用方能够观察由时序决定的实际路由。
-
-发送到现有 run 的消息没有独立结果，其效果体现在当前 Task 的最终结果中。启动的后续轮次具有新 Task 的结果，并使用现有 `task_output` 读取路径。subagent 层不会再注入第二份完成通知。
-
-用户输入使用同一个控制操作。UI 可以展示 child transcript 和当前 Task 状态，取消操作则以已加载 parent 作为调用方访问 Task 服务。工具 schema 与 UI 适配器消费同一个控制服务契约，不建立彼此独立的执行路径。
-
-### 持久化 child handle 与从持久化存储恢复
-
-控制服务在创建 Task 前，通过 [`snapshotJsonValue`](../../../../packages/core/session/src/json.ts) 对每项描述符输入建立快照；这一边界与 Agent 消息现有的分离式无损 JSON 边界一致。作用于 child 作用域的 setup contribution 会在 child 初始 `turn/start` 之后、首次请求之前追加一个对模型隐藏的 `subagent/descriptor` 事件。该事件不携带 `surfaceOp`，不进入模型历史，并随该轮次的 flush 一并进入持久化存储。当压缩替换 surface 历史时，仅追加日志仍保留这个不属于 surface 的事件。只有在加载已知 child id 对应的 child 会话后能得到受支持的描述符，且会话 header 将调用方标识为直接 parent 时，该 id 才可恢复。
-
-版本化描述符包含 subagent 提供方名称、已解析的 child `agentOptions.provider` 和 `agentOptions.model`，以及可选的 `persona` 与 `toolFilter`。它不会对可通过声明合并扩展的 `AgentOptions` 对象建立快照：与此无关的扩展值不会仅因无法表示为 JSON 而导致继续执行失败。描述符会特意省略 `subagentDepth`；从持久化存储恢复时，系统依赖持久化 header 中的 `delegationDepth`，而不根据描述符重建深度。`outputSchema` 属于单次激活的结果契约，不属于持久化 child 组合配置。child header 仍是 child id、`cwd`、`parentSession`、`seedLength` 和 `delegationDepth` 的权威信息，持久化 child transcript 则负责保存 fork seed 和后续历史。[`delegationDepthOf()`](../../../../packages/subagent/subagent/src/index.ts) 会在 header 值和运行时值中取最大值，因此重建后的运行时选项可以加深持久化值，但绝不能降低它，恢复后的 child 无法重新获得顶层委派预算。
-
-从持久化存储恢复不能依赖旧 `SubagentRun` 的可选方法，因为该 run 已被 dispose，并且进程重启后不会保留。本提案删除 `SubagentRun.resume?()`：run 表示一次可 dispose 的激活，只暴露作用于当前激活的操作。本提案还将现有 `SubagentRun.sendMessage?()` 功能改名为 `SubagentRun.steer?()`，以免其严格的仅在线契约与服务编排或面向模型的工具混淆。
-
-`SubagentControlService.resume()` 会加载已知 child 会话、归并其描述符、根据持久化的 `parentSession` 鉴权，并创建 Task。它向底层 `SubagentService.resume(provider, request)` 传递完全解析的请求，其中包含由 Task 持有的取消信号；后者只负责检查提供方功能后进行分发，并执行 `start` 所使用的普通 run 生命周期观察。选中的 `SubagentProvider.resume?()` 负责传输相关的重建，并返回一个新 run。提供方是否存在该方法本身就是继续执行功能，无需额外功能标志。`SubagentControlService.sendMessage()` 在关联 run 的 `steer?()` 操作与该持久化恢复路径之间做出选择。底层服务和提供方都不会枚举持久化 child 或关联 Task。
-
-后台工具会在调用 `TaskService.start()` 前校验描述符输入并建立快照。同步校验失败会拒绝工具调用，且不会创建 Task。除此之外，工具会立即返回 child id 和 Task id，不等待 child 发布或描述符持久化完成。child 创建、首轮持久化或描述符持久化失败时，系统会 dispose 所有已发布的 run，并将已经创建的 Task 结算为 `failed`；模型通过普通 Task 完成通知或 `task_output` 路径观察该失败。第一版会在当前已加载的 parent 作用域下重建进程内 spawn 和 fork 组合配置。恢复 fork 时只加载 child 自己的持久化 transcript，其中已经包含初始创建时捕获的已完成轮次前缀；系统绝不会再次 fork parent 更新后的历史。恢复 parent 不会立即恢复其 child。
-
-TODO（ACP 继续执行）：将远端 ACP session id 作为提供方专用描述符数据持久化，并实现 `AcpProvider.resume?()`，依次执行 spawn、initialize、`loadSession` 和 prompt。初始 ACP run 必须检查 `initialize.agentCapabilities.loadSession`，恢复后的每个进程必须使用同一个持久化后端；`loadSession` 回放的历史消息不得计入新激活的输出。由于 ACP 的加载支持是按 child 协商的，不能仅根据提供方是否存在该方法来确定，因此该后续工作还必须定义 start 结果如何声明单个 child 支持继续执行，之后才能将 ACP child 写入持久化目录。
-
-### 结果与通知所有权
-
-每次可继续 child 激活都恰好拥有一个 Task 和一个 `TaskOutcome`，无论第一条消息由 parent 还是用户提供。只要 Task 尚未标记为已报告，通用 Task 报告契约最多会向保留的 parent owner 注入一条主动完成通知；读取、等待和取消都可能抑制该通知。发送到运行中激活的消息会加入该激活，不会创建第二个 Task 或第二份结果。child transcript 是面向用户的详细记录；Task 输出是面向 parent 的最终结果。
-
-Task 记录和活跃 run 关联都位于进程内。持久化使 child 会话可在重启后恢复，但不会恢复中断的 Task、其结果或通知。持久化 Task 恢复属于另一个问题。
-
-### 实现边界
-
-一个实现 PR 会交付本提案：稳定 child id 的分配与提供方交接、child 会话描述符事件、`SubagentControlService`、进程内提供方从持久化存储恢复、现有后台委派路由、严格的 spawn／fork steering、活跃 run 关联、用户消息路由，以及单独加载的 `@deepseek-ai/dsh-tool-subagent-control` 包及其 `send_message` 工具。parent 到 child 的枚举与 `list_agents` 使用这份持久化 child handle 契约，但仍是单独的功能和 PR。解决上述按 child 声明支持的契约后，再通过单独的提供方改动支持 ACP 继续执行。
-
-## 已考虑的替代方案
-
-**在 Task 结算后保留所有后台 child。** 这是 Codex 风格的常驻会话模型：发送后续消息成本较低，但历史 child 会持续占用 agent 作用域、会话内存、监听器和提供方资源，直至显式常驻数量上限或淘汰策略将其移除。逐激活 dispose 使用持久化作为继续执行边界，同时保留当前的资源上限。
-
-**允许用户轮次不使用 Task。** parent 消息加入此类轮次后，没有对应的 Task 结果或完成通知；UI 取消对 parent 所发消息的影响也不明确。让每次激活都拥有一个 Task，可使完成与取消成为 child 轮次的属性，而不是初始调用方的属性。
-
-**在 child 会话整个生命周期内复用一个 Task。** 终态 Task 无法自然地再次进入运行状态，一个结果也无法表示多个轮次。每次激活创建新 Task 可以保留通用 Task 契约。
-
-**为每条消息创建 Task。** 发送到现有 run 的消息会加入已有轮次，不产生独立的最终结果；为这类消息创建 Task，会重复当前 Task，或报告一个它并不拥有的结果。只有启动新激活的消息才会创建 Task。
-
-**拆分 `send_message` 与 `follow_up`。** 两个严格操作会向模型暴露实现状态差异，却无法消除 child 已停止时的竞态。单一操作采用 Claude Code 模型：向运行中的工作发送消息，或恢复一个由新 Task 支撑的生命周期。
-
-**在已 dispose 的 run 上保留 `resume?()`。** 如果仅为调用 `resume()` 而保留已 dispose 的 `SubagentRun`，旧 run 会同时充当持久化 child handle，而且进程重启后无法重建该对象。由服务分发、提供方重建，可明确表达持久化边界。
-
-**将控制编排放在 `SubagentService` 上。** 这样一个服务就能查找描述符、关联 Task 并分发提供方，但会迫使不感知集合的提供方 seam 依赖某个消费方的持久化与 Task 策略。单独的控制服务让前台及不使用 Task 的消费方可以复用 start／resume 传输，同时为工具和 UI 提供统一的编排路径。
-
-**增加显式激活阶段。** 公开的 `starting`／`running`／`settling` 状态可以准确描述准入和清理，但会引入第一版实现并不需要的生命周期协议。暂缓实现的 promise 预留无需暴露这些阶段，即可消除进程内重复的 cold resume。
-
-## 验收标准
-
-- 初始及恢复后的可继续激活都会创建新 Task，并在该 Task 进入终态前 dispose 对应 run。
-- 打开持久化 child 仅用于展示时，不会创建 agent 激活；在 parent 已加载时，用户输入会启动或加入一个由 Task 支撑的激活。
-- 用户消息和 parent 消息发送到同一个运行中激活后，共享其 Task 结果和取消结果。
-- 取消用户启动的激活会中止并 dispose 对应 run，将 Task 结算为 `killed`；其完成通知遵循通用的至多一次报告契约，并且在 Task 已标记为已报告时可能被抑制。
-- 从持久化存储恢复的 Task 在描述符查找前就持有其 AbortSignal；查找描述符或执行提供方恢复期间发生取消时，系统不得在之后发布 run，若 run 已发布则会取消它。Task 只有在回滚或 dispose 完成、激活完全停稳后，才结算为 `killed`。
-- 用户界面适配器在接受 child 输入前会附加 Task 控制面；缺少控制面时明确失败，而不会启动未受跟踪的工作。
-- `send_message` 向运行中的 child 发送消息时不会创建 Task；向已停止的 child 发送消息时，会从持久化存储恢复并创建新的 Task 激活。
-- `send_message` 会以 `steered` 报告消息已加入现有 Task，或以 `started` 报告已启动新 Task，并携带相应 task id；失败时会报告消息未送达。
-- 初始可继续委派在创建 Task 前分配 child id，通过提供方发布路径传递该 id，并向模型返回稳定的 child id 与当前激活的 Task id。
-- spawn 和 fork 实现严格的 `SubagentRun.steer` 行为；检查运行状态与调用 `Agent.steer()` 之间不存在异步边界，在线消息不会 fallback 到未受跟踪的 Agent 轮次。
-- 严格 steering 在与 Task 结算的竞态中失败时，`send_message` 会报告消息未送达，而且不会在该次调用中从持久化存储恢复。
-- `SubagentRun` 不提供从持久化存储恢复的操作；`SubagentControlService.sendMessage()` 将活跃消息分发至 `run.steer?()`，将非活跃消息经由底层 `SubagentService.resume()` 分发至 `SubagentProvider.resume?()`。
-- `SubagentRun.sendMessage?()` 到 `steer?()` 的重命名和后台激活路由，会在同一 PR 中同步更新 seam 模块 JSDoc、各包 README、core-data-structures 目录，以及 `tool-subagent` 中 `settleRun` 的所有权文档和测试。
-- `SubagentService` 不感知 Task 与持久化描述符；`SubagentControlService` 负责可继续激活、鉴权、按已知 child id 查找描述符，以及工具和 UI 消费方使用的 Task／run 关联。
-- 每个受支持的可继续 child 轮次都会在等待提供方之前安装 Task 关联，并保留该关联直到 run dispose 完成；按 id 路由会拒绝存活的 `ctx.agents.get(childId)`，除非关联已存在，且其 `run.localAgent` 就是该 Agent。
-- parent 恢复后，系统可以对已知的持久化 child id 鉴权，并在恢复后的 parent 作用域下，以等价的声明式组合配置按需重建该 child；恢复 fork 时只使用 child 的持久化 transcript，绝不重新 fork parent 的当前历史。
-- 描述符输入会在创建 Task 前建立快照；带版本、对模型隐藏的描述符事件位于 child 会话轮次内，不属于 surface，在压缩后仍保留，并且只有在 child header 通过直接 parent 鉴权后才会被归并。描述符省略 `subagentDepth`，恢复时的深度以持久化 header 中的值为单调下界。
-- 描述符 JSON 无效会拒绝工具调用且不创建 Task，异步 child 创建或描述符持久化失败则会 dispose 对应 run，并将已经返回的 Task 结算为 `failed`。
-- 按提供方绑定的委派工具仍位于 `@deepseek-ai/dsh-tool-subagent`；全局命名的 `send_message` 工具由 `@deepseek-ai/dsh-tool-subagent-control` 注册一次。
-- 每次激活只产生一个 Task 结果和至多一条现有 Task 主动完成通知；读取、等待或取消可能抑制该通知，steering 和 subagent 层不会添加重复通知。
-- 测试记录已停止 child 的并发准入并非原子操作：一个相同会话的发布成功，失败的 Task 进入失败状态，且其消息不会被报告为已送达。
-- 无密钥包测试覆盖 Task 所有权、dispose 顺序、用户启动和取消、运行中消息、持久化后续轮次、描述符拒绝与回滚、按已知 id 重建、作用域重建，以及所有终态下的清理。面向模型的工具及 transcript 变更具有可运行的快照覆盖。
-
-## 风险
-
-- 每次完成结算后的后续轮次都需要承担持久化加载和作用域 setup 成本。持久化不可用或存储的组合配置无法重建时，可继续 child 的创建会明确失败。
-- 两个调用方可能同时观察到 child 已停止，并启动相互竞争的恢复。agent 注册表会阻止相同会话的重复发布，但失败的 Task 不会送达其消息。消息也可能与取消、终态发布或 run dispose 发生竞态。第一版不承诺原子准入或恰好执行一次语义；暂缓实现的进程内 promise 预留无需公开生命周期状态机，即可消除重复的 cold resume。
-- 通过普通 Agent API 驱动可继续 child 会绕过其 Task 关联。控制服务会将该存活 child 视为所有权冲突并拒绝；适配器必须在不加载 Agent 的情况下展示持久化 transcript，并通过 `SubagentControlService.sendMessage()` 提交用户输入。
-- 活跃 run 关联只能协调一个运行时。多个进程同时恢复时不会串行化；此类部署需要持久化层的租约或 compare-and-set 操作。
-- 用户交互要求 Task 注册表中作为 owner 的那个 parent agent 实例保持存活，因为 dispose owner 会取消并移除其 Task。用户交互还要求附加 Task 控制面。若要单独与 child 交互，后续必须将 Task 访问所有权与持久化通知目标分离。
-- 后台工具会在 child 发布和描述符持久化之前返回 child id 和 Task id。启动失败、持久化失败，或进程在 child 首次 flush 之前退出，都可能留下 unmaterialized child id；按 id 的控制操作会报告该 id 不可用，持久化枚举也不会列出它，而不会追溯修改工具返回结果。
-- 将显式组合字段持久化到 child 日志后，其无损 JSON 与兼容性契约便成为恢复契约的一部分。后续如需支持其他组合配置输入，必须明确更改描述符版本，不能隐式持久化可通过声明合并扩展的 `AgentOptions` 字段。
-- Task 记录和活跃 run 关联位于进程内，而 child 会话具有持久性。重启会恢复会话，但不会恢复进行中的工作或其 Task 通知。

+## Continuable children: `SubagentContinuation` and `SubagentResumeRequest`
+
+A **continuable background subagent** is a durable child session with a series of Task-backed activations. `ctx.subagentControl` (`SubagentControlService` in [dsh-subagent-control](../../packages/subagent/subagent-control)) allocates the stable child id, snapshots the versioned `subagent/descriptor` payload, and passes both through the resolved start request; the provider publishes exactly that id and appends the descriptor inside the child's first turn. On follow-up, the control service loads the persisted child, authorizes the recorded `parentSession` as the direct parent, folds the descriptor, and dispatches a fully resolved resume request through `SubagentService.resume()` to `SubagentProvider.resume()`. The seam stays Task- and persistence-agnostic — descriptor lookup and Task association live only in the control service. `startContinuable()` returns a `ContinuableStart` (both identities), and `sendMessage()` returns a `SendMessageResult` reporting whether the message `steered` the running activation's existing Task or `started` a fresh one.

Your working directory is {{cwd}}.\n\nVerify your work by running the code or tests. Keep answers brief and factual.\n\n\nUse the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.\n\nUse the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.\n\nCheck the [exit code: N] marker on every bash result; investigate failures before moving on.\n\nTrack every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.\n\nUse the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.\n\n## Writing code for run_code\n\nPass `run_code` the body of an async TypeScript function (erasable syntax only — no `enum` or namespaces; type annotations are advisory, the code runs type-stripped). Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Independent read-only calls MAY overlap under `Promise.all` (safe calls run concurrently; mutating calls run alone, in submission order). Sequence dependent work with `await`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ntype JsonValue = null | boolean | number | string | JsonValue[] | { [key: string]: JsonValue }\n\ninterface ToolArgsMap {\n  /** Execute a bash command (`bash -c`) and return its stdout/stderr.

This creates an in-memory runtime Plugin, not an installed or configured Plugin. It remains active across later turns until cordis_unmount, toolset unload, or DSH restart. It does not create files, install a package, change cordis.yml or personal/project config, survive restart, or automatically become permanent. To keep it, ask the Agent to implement a normal local, project, or repository Plugin through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime. */\n  cordis_mount: {\n    /** JavaScript body returning a temporary Plugin; evaluated now and saved nowhere. */\n    code: string;\n  } & Record;\n  /** Unmount a current-process temporary Plugin created by cordis_mount.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn. The workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result. Script-body hooks: - `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly. - `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages. - `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`. - `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim. Misused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`. Constraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks.

The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

Your working directory is {{cwd}}.\n\nVerify your work by running the code or tests. Keep answers brief and factual.\n\n\nUse the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.\n\nUse the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.\n\nCheck the [exit code: N] marker on every bash result; investigate failures before moving on.\n\nTrack every background task id you start.

Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results.

Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.\n\n## Writing code for run_code\n\nPass `run_code` the body of an async TypeScript function (erasable syntax only — no `enum` or namespaces; type annotations are advisory, the code runs type-stripped). Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Independent read-only calls MAY overlap under `Promise.all` (safe calls run concurrently; mutating calls run alone, in submission order). Sequence dependent work with `await`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ntype JsonValue = null | boolean | number | string | JsonValue[] | { [key: string]: JsonValue }\n\ninterface ToolArgsMap {\n  /** Execute a bash command (`bash -c`) and return its stdout/stderr.

The workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result.

This creates an in-memory runtime Plugin, not an installed or configured Plugin. It remains active across later turns until cordis_unmount, toolset unload, or DSH restart. It does not create files, install a package, change cordis.yml or personal/project config, survive restart, or automatically become permanent. To keep it, ask the Agent to implement a normal local, project, or repository Plugin through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime.","parameters":{"type":"object","properties":{"code":{"type":"string","description":"JavaScript body returning a temporary Plugin; evaluated now and saved nowhere."}},"required":["code"]}},{"name":"cordis_unmount","description":"Unmount a current-process temporary Plugin created by cordis_mount.

Your working directory is {{cwd}}.\n\nVerify your work by running the code or tests. Keep answers brief and factual.\n\n\nUse the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.\n\nUse the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.\n\nCheck the [exit code: N] marker on every bash result; investigate failures before moving on.\n\nTrack every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.\n\nUse the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.\n\n## Writing code for run_code\n\nPass `run_code` the body of an async TypeScript function (erasable syntax only — no `enum` or namespaces; type annotations are advisory, the code runs type-stripped). Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Independent read-only calls MAY overlap under `Promise.all` (safe calls run concurrently; mutating calls run alone, in submission order). Sequence dependent work with `await`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ntype JsonValue = null | boolean | number | string | JsonValue[] | { [key: string]: JsonValue }\n\ninterface ToolArgsMap {\n  /** Execute a bash command (`bash -c`) and return its stdout/stderr.

This creates an in-memory runtime Plugin, not an installed or configured Plugin. It remains active across later turns until cordis_unmount, toolset unload, or DSH restart. It does not create files, install a package, change cordis.yml or personal/project config, survive restart, or automatically become permanent. To keep it, ask the Agent to implement a normal local, project, or repository Plugin through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime. */\n  cordis_mount: {\n    /** JavaScript body returning a temporary Plugin; evaluated now and saved nowhere. */\n    code: string;\n  } & Record;\n  /** Unmount a current-process temporary Plugin created by cordis_mount.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn. The workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result. Script-body hooks: - `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly. - `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages. - `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`. - `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.

This creates an in-memory runtime Plugin, not an installed or configured Plugin. It remains active across later turns until cordis_unmount, toolset unload, or DSH restart. It does not create files, install a package, change cordis.yml or personal/project config, survive restart, or automatically become permanent. To keep it, ask the Agent to implement a normal local, project, or repository Plugin through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime.","parameters":{"type":"object","properties":{"code":{"type":"string","description":"JavaScript body returning a temporary Plugin; evaluated now and saved nowhere."}},"required":["code"]}},{"name":"cordis_unmount","description":"Unmount a current-process temporary Plugin created by cordis_mount.

Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files.

Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Independent read-only calls MAY overlap under `Promise.all` (safe calls run concurrently; mutating calls run alone, in submission order). Sequence dependent work with `await`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ntype JsonValue = null | boolean | number | string | JsonValue[] | { [key: string]: JsonValue }\n\ninterface ToolArgsMap {\n  /** Execute a bash command (`bash -c`) and return its stdout/stderr.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn. The workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result. Script-body hooks: - `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly. - `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages. - `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`. - `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim. Misused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`. Constraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

Your working directory is {{cwd}}.\n\nVerify your work by running the code or tests. Keep answers brief and factual.\n\n\nUse the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.\n\nUse the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.\n\nCheck the [exit code: N] marker on every bash result; investigate failures before moving on.\n\nTrack every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.\n\nUse the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.\n\n## Writing code for run_code\n\nPass `run_code` the body of an async TypeScript function (erasable syntax only — no `enum` or namespaces; type annotations are advisory, the code runs type-stripped). Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Independent read-only calls MAY overlap under `Promise.all` (safe calls run concurrently; mutating calls run alone, in submission order). Sequence dependent work with `await`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ntype JsonValue = null | boolean | number | string | JsonValue[] | { [key: string]: JsonValue }\n\ninterface ToolArgsMap {\n  /** Execute a bash command (`bash -c`) and return its stdout/stderr.

It does not create files, install a package, change cordis.yml or personal/project config, survive restart, or automatically become permanent. To keep it, ask the Agent to implement a normal local, project, or repository Plugin through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime. */\n  cordis_mount: {\n    /** JavaScript body returning a temporary Plugin; evaluated now and saved nowhere. */\n    code: string;\n  } & Record;\n  /** Unmount a current-process temporary Plugin created by cordis_mount.

Script-body hooks: - `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly. - `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages. - `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`. - `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim. Misused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`. Constraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them. The run executes in the foreground: this call returns when the whole script finishes. */\n  workflow: {\n    /** The plain-JS workflow script body (top-level await allowed; NO `export const meta` statement; end with `return `). */\n    script: string;\n    /** The workflow identity block (plain JSON — never code). */\n    meta: {\n      /** Short kebab-case workflow name. */\n      name: string;\n      /** One-line description of what the workflow does. */\n      description: string;\n      /** Optional guidance on when this workflow applies. */\n      whenToUse?: string;\n      /** Optional phase declarations matched by phase() calls. */\n      phases?: ({\n        /** The phase title phase() calls match by exact string. */\n        title: string;\n        /** Optional one-line description of the phase. */\n        detail?: string;\n        /** Optional provider override this phase is expected to use. */\n        provider?: string;\n        /** Optional model override this phase is expected to use. */\n        model?: string;\n      } & Record)[];\n    } & Record;\n    /** Optional JSON input exposed to the script as the `args` global (wrap a bare list as a field, e.g. {\"files\": [...]}). */\n    args?: Record;\n  } & Record;\n  /** Create or fully replace a UTF-8 text file. */\n  write: {\n    /** Path to write, resolved by the filesystem backend. */\n    file_path: string;\n    /** Full UTF-8 text content to write. */\n    content: string;\n  } & Record;\n}\n\ninterface ToolOutputMap {\n  bash: {\n    kind: \"background\";\n    taskId: string;\n  } | {\n    kind: \"foreground\";\n    exitCode: number | null;\n    signal: string | null;\n    timedOut: boolean;\n    aborted: boolean;\n    timeoutMs: number;\n    stdout: {\n      text: string;\n      truncated: boolean;\n      spillPath?: string;\n    };\n    stderr: {\n      text: string;\n      truncated: boolean;\n      spillPath?: string;\n    };\n    sandbox?: {\n      mode: string;\n      denied: boolean;\n      enforcement?: string;\n      runnerFailed?: boolean;\n    };\n  };\n  cordis_inspect: string;\n  cordis_mount: {\n    id: string;\n    pluginName: string;\n    state: \"pending\" | \"loading\" | \"active\" | \"failed\" | \"disposed\" | \"unloading\";\n    provides: string[];\n    waitingFor: string[];\n  };\n  cordis_unmount: {\n    id: string;\n    pluginName: string;\n  };\n  edit: {\n    path: string;\n    before: string;\n    after: string;\n  };\n  ralph: {\n    runId: string;\n    agentsStarted: number;\n    result: JsonValue;\n  };\n  read: {\n    path: string;\n    offset: number;\n    lines: {\n      number: number;\n      text: string;\n    }[];\n    totalLines: number;\n  };\n  skill: {\n    name: string;\n    provider: string;\n    resourceBase?: {\n      kind: \"directory\";\n      path: string;\n    } | {\n      kind: \"url\";\n      url: string;\n    } | {\n      kind: \"opaque\";\n      description: string;\n    };\n    content: string;\n  };\n  subagent: {\n    kind: \"background\";\n    taskId: string;\n  } | {\n    kind: \"foreground\";\n    runId: string;\n    output: JsonValue[];\n  };\n  subagent_fork: {\n    kind: \"background\";\n    taskId: string;\n  } | {\n    kind: \"foreground\";\n    runId: string;\n    output: JsonValue[];\n  };\n  task_kill: {\n    outcome: \"cancellation-requested\" | \"already-finished\";\n    task: {\n      id: string;\n      kind: string;\n      label: string;\n      status: \"running\" | \"stopping\" | \"completed\" | \"killed\" | \"failed\";\n      detail?: string;\n      startedAt: number;\n      finishedAt?: number;\n    };\n  };\n  task_list: ({\n    id: string;\n    kind: string;\n    label: string;\n    status: \"running\" | \"stopping\" | \"completed\" | \"killed\" | \"failed\";\n    detail?: string;\n    startedAt: number;\n    finishedAt?: number;\n  })[];\n  task_output: {\n    text: string;\n    task: {\n      id: string;\n      kind: string;\n      label: string;\n      status: \"running\" | \"stopping\" | \"completed\" | \"killed\" | \"failed\";\n      detail?: string;\n      startedAt: number;\n      finishedAt?: number;\n    };\n  };\n  todo_write: {\n    todos: ({\n      content: string;\n      status: \"pending\" | \"in_progress\" | \"completed\";\n    })[];\n    counts: {\n      pending: number;\n      inProgress: number;\n      completed: number;\n    };\n  };\n  workflow: {\n    runId: string;\n    agentsStarted: number;\n    result: JsonValue;\n  };\n  write: {\n    path: string;\n    operation: \"create\" | \"update\";\n    before: string | null;\n    after: string;\n  };\n}\n\ntype ToolName = keyof ToolOutputMap\n\ndeclare class ToolCallError extends Error {\n  readonly name: \"ToolCallError\";\n  readonly toolName: ToolName;\n}\n\ndeclare const tools: {\n  [K in ToolName]: (args: ToolArgsMap[K]) => Promise;\n}\n```","tools":[{"name":"bash","description":"Execute a bash command (`bash -c`) and return its stdout/stderr.

This creates an in-memory runtime Plugin, not an installed or configured Plugin. It remains active across later turns until cordis_unmount, toolset unload, or DSH restart. It does not create files, install a package, change cordis.yml or personal/project config, survive restart, or automatically become permanent. To keep it, ask the Agent to implement a normal local, project, or repository Plugin through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime.","parameters":{"type":"object","properties":{"code":{"type":"string","description":"JavaScript body returning a temporary Plugin; evaluated now and saved nowhere."}},"required":["code"]}},{"name":"cordis_unmount","description":"Unmount a current-process temporary Plugin created by cordis_mount.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn. The workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result. Script-body hooks: - `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly. - `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages. - `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`. - `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim. Misused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`. Constraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.\n\nCheck the [exit code: N] marker on every bash result; investigate failures before moving on.\n\nUse a terminal session only when work needs persistent terminal state or interactive stdin; prefer bash/read/write/edit for bounded one-shot operations. Track every terminal session id and close sessions that no longer matter. An inferred_idle or timeout result does not prove the foreground command exited.\n\nTrack every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.\n\nUse the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.","tools":[{"name":"bash","description":"Execute a bash command (`bash -c`) and return its stdout/stderr.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn.\n\nThe workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

+# @deepseek-ai/dsh-subagent-control
+
+The continuable-subagent control service (`ctx.subagentControl`): the one orchestration path that binds a durable child session to a series of disposable Task-backed activations. Model tools and human-facing adapters call the same contract; the low-level `ctx.subagents` seam stays collection-, Task-, and persistence-agnostic.
+
+## Activation lifecycle
+
+A continuable background subagent is a durable child session with a series of Task-backed activations. `startContinuable()` allocates the stable child session id before Task creation, snapshots the descriptor inputs (a non-JSON input throws with no Task), and registers the initial activation's Task; the provider publishes exactly that child id and appends the versioned `subagent/descriptor` event inside the child's first turn. Every activation — initial or resumed — creates a fresh Task whose settlement awaits the child result, disposes the run, and only then records the `TaskOutcome`: a terminal Task leaves the durable child session but no live child Agent.
+
+`sendMessage(parent, childId, message)` owns steer-or-resume routing. A running activation receives live delivery through the run's strict `steer` capability and returns the existing Task id (`steered`); an absent activation starts a fresh Task that loads the persisted child, authorizes the recorded `parentSession` as the direct parent, folds the descriptor, and dispatches `SubagentService.resume()` (`started`). Failure throws and means the message was not delivered: losing a strict-steering race with Task settlement never falls through to cold resume within the same call, and a live registry Agent outside the activation association is an ownership conflict rather than an adoption target.
+
+Cancellation targets the whole activation. `task_kill` or owner disposal aborts the Task-owned signal; before publication the provider rejects only after its creation transaction rolled back to quiescence, afterwards the signal cancels the published run, and settlement records `killed` only once the activation is quiescent. Human input shares this path: an adapter submits child input through `sendMessage()` under the loaded parent, so parent and human messages that joined one turn share its result and cancellation outcome, and `TaskService.start()`'s control-surface requirement applies (load `@deepseek-ai/dsh-tool-tasks` or attach a surface).
+
+The activation association is process-local routing state, installed before any persistence or provider await and removed after run disposal and Task terminal publication. It is not a durable catalog: restart recovers the child session, not in-flight Tasks or their notifications.
+
+## Model Experience
+
+### Task completion and output
+
+#### What the model sees
+
+None directly, as this package registers no tool and no prompt text; the model observes continuable children through `@deepseek-ai/dsh-tool-subagent`'s background acknowledgement, `@deepseek-ai/dsh-tool-subagent-control`'s `send_message` results, and the generic task surface, whose outputs this service produces.
+
+#### Token effect
+
+None beyond the consuming tools' own results.
+
+#### KV Cache effect
+
+None; this service appends nothing to any model-visible sequence.
+
+## Known Limitations and Deferred Work
+
+- **Concurrent stopped-child admission is not atomic across awaits** — the synchronous association install admits one activation per child in this process, but a caller bypassing the control service can still race it; the Agent registry's same-id collision is the final backstop, and the losing Task fails with its message not delivered.
+- **The association coordinates only one runtime** — concurrent resume from multiple processes needs a persistence-level lease or compare-and-set, which no backend offers yet.
+- **Task records are process-local** — restart recovers the durable child session, not an interrupted Task, its result, or its completion notice; durable Task recovery is a separate concern.
+- **Human interaction requires the exact live parent Agent** — Task access is fenced by the owner session and owner disposal cancels its Tasks; standalone child conversations belong to the interactive-side-sessions proposal, not this Task-owned lifecycle.
+- **ACP children remain one-shot** — `AcpProvider.resume` and per-child continuation advertisement are deferred until the remote-session descriptor contract is resolved.

During that transaction's unpublished setup window, install the requested persona, tool restriction, structured-output runtime, and — for a continuable request — the one-shot `agent/pre-step` contribution that appends the `subagent/descriptor` event after the initial `turn/start` and before the first request, so the descriptor reaches persistence with that turn's flush.

+5. Read the child's own last assistant message and latest message-triggered turn reason, excluding any fork seed and later plugin-owned zero-step turns.
 
 The child gets the parent's working-directory/session lineage and inherits the parent provider, model, and output-token cap unless `request.agentOptions` overrides them. It gets a fresh flat registration scope: parent ownership does not import parent tool restrictions or establish an authority subset.
 
 When the optional sandbox-policy or approval service is composed, the driver snapshots the parent's explicit session override before child creation and appends a source-tagged event during unpublished setup, after any fork history and before session publication. It never copies deployment defaults or one-shot grants; later child switches still win. See the [policy-inheritance decision](../../../.agents/notes/implemented/feature/2026-07-25-subagent-policy-inheritance.md).
 
+## Cold resume
+
+`resumeInProcessRun(request): Promise` reconstructs a persisted continuable child under the live parent's scope: `parent.ctx.agents.resume` loads the child's own transcript through persistence (a fork child's log already contains its seed prefix, so resume never re-forks current parent history), the descriptor's persona and tool filter are reapplied in the unpublished setup window, and the descriptor's `agentProvider`/`agentModel` become the runtime options. The persisted header stays authoritative for lineage and the delegation-depth floor. The activation's result boundary is the resumed log length: only this follow-up turn's output becomes the run result. Publication, abort handoff, and disposal follow the same contract as start.
+
 ## Cancellation and ownership
 
 The required request signal covers both startup and the live run. Before publication, `AgentCreationTransaction` observes it, rolls back, and rejects. The factory detaches that creation-only listener before returning; the driver immediately checks the signal once more before installing a minimal live-run listener, closing the handoff race. After publication, abort cancels the child.
 
 After fulfillment, the caller owns the run. Provider-plugin unload does not revoke it. `dispose()` removes the live abort listener, records cancellation, and delegates to the returned `AgentHandle.dispose()`, whose memoized quiescence transaction stops the loop, removes the agent and session, and unwinds scoped registrations. Cancellation owns every non-completed in-flight outcome and reports `aborted`; an already-completed turn remains completed.
 
+Runs expose the strict `steer` capability: a synchronous `AgentStatus.running` check and `Agent.steer()` call share one frame, so delivery joins the observed turn or throws. The Agent-level idle fallback (queue and start a new turn) is deliberately not reachable through the run — that would start an untracked turn after the run's result was read.

 子 agent 会获得父 agent 的工作目录／会话谱系；除非 `request.agentOptions` 覆盖，否则还会继承父 agent 的提供方、模型和输出 token 上限。它获得全新的扁平注册作用域：父级所有权不会导入父 agent 的工具限制，也不会建立权限子集。
 
 当组合中挂载了可选的沙箱策略或审批服务时，驱动器会在创建子 agent 前对父级的显式会话覆盖项获取快照，并在未发布的设置阶段追加一条带来源标记的事件，使其位于所有 fork 历史之后、会话发布之前。它绝不复制部署默认值或一次性授权；子 agent 后续的切换仍然优先。参见[策略继承决策](../../../.agents/notes/implemented/feature/2026-07-25-subagent-policy-inheritance.md)。
 
+## 冷恢复
+
+`resumeInProcessRun(request): Promise` 会在当前父级作用域下重建持久化的可继续子 agent：`parent.ctx.agents.resume` 通过持久化层加载子 agent 自身的 transcript（文本记录；fork 子 agent 的日志已经包含初始前缀，因此恢复绝不会再次 fork 当前父级历史），在未发布的设置窗口中重新应用描述符中的 persona 和工具过滤器，并把描述符中的 `agentProvider` / `agentModel` 作为运行时选项。持久化 header 对谱系和委派深度下限保持权威性。activation 的结果边界是恢复后日志的长度：只有此次后续轮次的输出会成为运行结果。发布、中止交接和 dispose 遵循与启动相同的契约。
+
 ## 取消与所有权
 
 必需的请求信号同时覆盖启动阶段和实时运行。发布前，`AgentCreationTransaction` 会观察该信号、回滚并拒绝。工厂返回前会移除仅用于创建阶段的监听器；驱动器随即再次检查信号，然后安装最小化的实时运行监听器，从而消除交接竞态。发布后，中止会取消子 agent。
 
 兑现后，调用方拥有该运行。提供方插件卸载不会撤销它。`dispose()` 会移除实时中止监听器、记录取消，并委托给返回的 `AgentHandle.dispose()`；后者通过可复用的完全停稳事务停止循环、移除 agent 和会话，并展开有作用域的注册。取消决定所有尚未完成的进行中结果，并将其报告为 `aborted`；已经完成的轮次仍保持完成状态。

+Runtime features are optional methods whose presence is the capability check: `SubagentRun.steer?` delivers strictly to the actively running child turn (it throws rather than queueing when the child is not running), and `SubagentProvider.resume?` reconstructs a persisted continuable child. A run represents one disposable activation, so it deliberately has no cold-resume operation — a disposed run cannot be reconstructed after restart.
+
+## The durable descriptor
+
+The seam owns the versioned `subagent/descriptor` session event vocabulary (`src/descriptor.ts`): `snapshotSubagentDescriptor()` validates and detaches the declared composition before any Task exists, and `foldSubagentDescriptor()` recovers it from a loaded child log. The payload records the provider name, resolved child `agentOptions.provider`/`model`, and optional `persona`/`toolFilter` — explicit fields, never the merge-extensible `AgentOptions` object, so an unrelated extension value cannot break continuation. It omits `subagentDepth` (the persisted header's `delegationDepth` is the monotone floor) and `outputSchema` (an activation's result contract). The event is log-only: no `surfaceOp`, absent from model history, and retained by the append-only log across compaction.
+
 ## Delegation depth
 
 The seam owns the depth vocabulary shared by implementations and consumers: the `AgentOptions.subagentDepth` declaration, `assertSubagentMaxDepth`, and `delegationDepthOf(agent)`. The persisted `SessionHeader.delegationDepth` is authoritative and monotone — runtime options may deepen the count but never lower it, so a resumed child cannot be re-counted as top-level.
 
-Runtime features are optional methods on `SubagentRun`: `sendMessage?` steers a live child, while `resume?` asynchronously creates a continuation run. Method presence is the capability check.
-
 `inheritsParentContext` is descriptive rather than enforceable. It says only whether the child sees completed parent conversation history (`fork` does; `spawn` and ACP do not), not whether it inherits tools, services, or authority.
 
 ## Ownership and lifecycle
 
-`provider.start(request): Promise` is the ownership-transfer boundary. Before fulfillment, the provider owns setup and must cancel, roll back, and quiesce partial resources on every failure. After fulfillment, the caller owns the run and must call `dispose()` on every path.

After fulfillment, the caller owns the run and must call `dispose()` on every path. `provider.resume?(request)` shares the same contract for a resumed activation.
 
 `SubagentRun.result` resolves to `{ output, structured?, stopReason }`. Child-level failures resolve with a non-`completed` reason; only an infrastructure fault that the seam cannot represent may reject. `dispose()` is idempotent, cancels remaining work, and waits for the child resources to quiesce.
 
-A local run publishes an ordinary child agent/session before `start()` fulfills, returns that shared session id as `SubagentRun.id`, exposes the exact child as `SubagentRun.localAgent`, and records `request.parent.session.id` in the child's `parentSession` header.

 ## Known Limitations and Deferred Work
 
-- **Runtime steering and continuation are seam-only capabilities** — `sendMessage` and `resume` have no model-facing consumer in the current tool.
+- **ACP children remain one-shot** — `AcpProvider.resume` requires persisting the remote session id in provider-specific descriptor data and a per-child continuation advertisement, since ACP `loadSession` support is negotiated per child rather than established by the provider method's presence.
 - **Lifecycle events are observe-only** — a run-affecting `subagent/end` continuation or decision surface waits for a concrete consumer.

+# @deepseek-ai/dsh-tool-subagent-control
+
+The globally named `send_message` tool: a thin adapter over `ctx.subagentControl.sendMessage()`. Provider-bound `@deepseek-ai/dsh-tool-subagent` instances register distinct delegation tools per transport; this separately loaded package registers the one shared control tool, so multiple delegation tools never register duplicate global controls.
+
+The tool performs no lifecycle routing. The control service decides between live delivery to the running activation's existing Task and a fresh Task that cold-resumes the durable child; the tool renders which route was taken and the relevant Task id. A control-service throw becomes an errored tool result stating the message was not delivered.
+
+## Model Experience
+
+### Tool schema
+
+#### What the model sees
+
+The generated [`send_message` schema](../../../docs/tool-catalog.md#deepseek-aidsh-tool-subagent-control): `subagent_id` and `message`, with delivery-or-continue semantics and the `task_output` collection path described.
+
+#### Token effect
+
+Fixed schema cost per parent request.
+
+#### KV Cache effect
+
+Prefix-stable; the schema does not change at runtime.
+
+### Delivery result
+
+#### What the model sees
+
+`message delivered to running task ` when the message joined the running activation, or `message started task  continuing subagent ` when it cold-resumed the child. Failures are errored results whose message states the message was not delivered (unknown or foreign child, ownership conflict, settlement race, no live-delivery capability).
+
+#### Token effect
+
+One short acknowledgement per call; the child's response enters parent history only when collected through `task_output` or injected by the task completion notice.
+
+#### KV Cache effect
+
+Append-only; newly visible content follows the reusable request prefix and does not invalidate existing KV-cache entries.
+
+## Known Limitations and Deferred Work
+
+- **A delivered message has no independent result** — its effect is reflected in the current Task's eventual result; only a started follow-up owns a fresh Task result.
+- **Delivery can lose timing races** — a message racing task settlement, cancellation, or cleanup fails explicitly rather than falling through to cold resume; the model retries after the task settles.

macOS realpaths temp dirs into /private. The normalizer only stripped
the /private prefix for TMPDIR under /var; a TMPDIR under /tmp (any
explicitly relocated temp root) left one side canonicalized and the
comparison failing. Accept both shapes.

Subject: [PATCH 339/557] fix: address codex review round 1

- Strict steer now rejects the two windows where an acknowledged
  message would be silently dropped: the closed-turn durability-flush
  window (status still running, loop strands drained steering) and a
  committed structured capture (terminal turn-stop discards late
  steering). Seam JSDoc, catalog doc, README, and the Agent Note
  bilingual pair state the tightened contract; new keyless tests pin
  both rejections.
- Continuable background delegation now fails loud when the advertised
  send_message tool is not registered, instead of starting a durable
  child the model cannot continue. The acp-agent example already loads
  the control tool; the tool-catalog boot recipe is unaffected because
  capability wording is harvested at mount.

 Every continuable child turn is admitted through this Task-backed path. A non-terminal Task is the only supported live activation; when no activation exists, its run has already been disposed and the durable child is resumable. Before routing any by-id operation, the control service synchronously compares its association with `ctx.agents.get(childId)`. A registry Agent with no association, or a registry Agent different from the associated `run.localAgent`, is an ownership conflict: the control service fails rather than adopting an idle Agent or attaching an untracked turn. When neither exists, cold resume may proceed; a competing publication after that check still loses at the Agent registry collision boundary.
 
-Routing follows the Task association. A running Task accepts live delivery through the run's optional strict `SubagentRun.steer` capability. An absent Task starts a fresh Task and cold-resumes the child. In-process spawn and fork implement this capability by synchronously requiring `AgentStatus.running` before calling `Agent.steer()`; the check and call contain no asynchronous boundary. Providers must not expose the Agent-level idle fallback as strict steering, because that fallback may start an untracked turn after the observed run has ended. If the Task settles between association lookup and this strict check, `steer()` fails, `send_message` reports the message as not delivered, and that call does not fall through to cold resume; a later retry after Task terminal may start the next activation.
+Routing follows the Task association. A running Task accepts live delivery through the run's optional strict `SubagentRun.steer` capability. An absent Task starts a fresh Task and cold-resumes the child. In-process spawn and fork implement this capability with synchronous checks that share one frame with the `Agent.steer()` call: the child must be `running`, its turn must still be open in the log (status stays `running` through a closed turn's durability flush, where the loop strands drained steering), and no structured capture may have committed (its terminal stop makes the loop discard late steering). Providers must not expose the Agent-level idle fallback as strict steering, because that fallback may start an untracked turn after the observed run has ended. If the Task settles between association lookup and this strict check, `steer()` fails, `send_message` reports the message as not delivered, and that call does not fall through to cold resume; a later retry after Task terminal may start the next activation.
 
 The control service does not serialize two callers that race a stopped child through paths outside it, nor does it model a separate settling phase between result production and disposal. The synchronous association install before the producer's first await admits one activation per child in this process — a competing `sendMessage` during resume load observes the pending activation and fails explicitly — while a bypassing publication still loses at the Agent registry's same-session collision boundary. Delivery racing startup, cancellation, completion, or cleanup may also fail. These limitations are explicit rather than hidden behind a larger lifecycle abstraction.

 每个可继续 child 轮次都通过这条由 Task 支撑的路径准入。非终态 Task 是唯一受支持的存活激活；不存在激活时，其 run 已被 dispose，持久化 child 可以恢复。在路由任何按 id 的操作之前，控制服务会同步将自身关联与 `ctx.agents.get(childId)` 比较。如果注册表中的 Agent 没有关联，或者它与所关联的 `run.localAgent` 不同，就属于所有权冲突：控制服务会失败，而不会接管 idle Agent 或附加未受跟踪的轮次。二者均不存在时，可以从持久化存储恢复；如果检查后又有竞争方发布，仍会在 Agent 注册表的冲突边界上失败。
 
-系统依据 Task 关联进行路由。运行中的 Task 通过 run 可选且严格的 `SubagentRun.steer` 功能接收在线消息。Task 不存在时，系统创建新 Task，并从持久化存储恢复 child。进程内 spawn 和 fork 通过以下方式实现该功能：调用 `Agent.steer()` 前同步要求 `AgentStatus.running`，检查与调用之间不存在异步边界。提供方不得将 Agent 层的 idle fallback 暴露为严格 steering（中途引导），因为观察到的 run 结束后，该 fallback 可能启动一个未受 Task 跟踪的轮次。如果 Task 在查找关联与执行这项严格检查之间进入结算，`steer()` 会失败，`send_message` 会报告消息未送达，而且该次调用不会改用从持久化存储恢复路径；在 Task 终态发布后重试，才可能启动下一次激活。
+系统依据 Task 关联进行路由。运行中的 Task 通过 run 可选且严格的 `SubagentRun.steer` 功能接收在线消息。Task 不存在时，系统创建新 Task，并从持久化存储恢复 child。进程内 spawn 和 fork 用与 `Agent.steer()` 调用共享同一同步帧的检查来实现该功能：child 必须处于 `running` 状态，其轮次在日志中必须仍然打开（已关闭轮次的持久化 flush 期间状态仍是 `running`，此时循环会丢弃排空的 steering 消息），且不得已有结构化捕获提交（其终止性 stop 会让循环丢弃迟到的 steering）。提供方不得将 Agent 层的 idle fallback 暴露为严格 steering（中途引导），因为观察到的 run 结束后，该 fallback 可能启动一个未受 Task 跟踪的轮次。如果 Task 在查找关联与执行这项严格检查之间进入结算，`steer()` 会失败，`send_message` 会报告消息未送达，而且该次调用不会改用从持久化存储恢复路径；在 Task 终态发布后重试，才可能启动下一次激活。
 
 控制服务不会串行化两个通过其外部路径同时争抢已停止 child 的调用方，也不会为结果产生与 dispose 之间的阶段单独建立 settling 状态。在 producer 首次 await 之前同步安装的关联，使本进程内每个 child 只准入一次激活——resume 加载期间竞争的 `sendMessage` 会观察到待处理的激活并显式失败——而绕开该关联的发布仍会在 Agent 注册表相同会话的冲突边界上失败。发送也可能因与启动、取消、完成或清理发生竞态而失败。这些限制是明确的，而非隐藏在更大的生命周期抽象之后。

 After fulfillment, the caller owns the run. Provider-plugin unload does not revoke it. `dispose()` removes the live abort listener, records cancellation, and delegates to the returned `AgentHandle.dispose()`, whose memoized quiescence transaction stops the loop, removes the agent and session, and unwinds scoped registrations. Cancellation owns every non-completed in-flight outcome and reports `aborted`; an already-completed turn remains completed.

+Runs expose the strict `steer` capability: the synchronous checks and the `Agent.steer()` call share one frame, so delivery joins the observed turn or throws. Delivery requires `AgentStatus.running`, an open turn in the child log (status stays `running` through a closed turn's durability flush, where the loop would strand the message), and no committed structured capture (whose terminal stop makes the loop discard late steering).

Subject: [PATCH 340/557] fix: address codex review round 2

- Wire the control service and send_message tool into every shipped
  composition with a resumable provider and background enabled
  (headless-agent, tui-agent, and the SDK helper's subagent feature
  base resources); jsonrpc-agent disables background and is unchanged.
- Resolve the send_message availability check in the CALLER's tool
  scope so a restriction that removes the follow-up tool from one
  agent also blocks that agent's continuable start.
- Control-service disposal now cancels live activations and awaits
  producer settlement instead of stranding them: TaskService keeps
  producer Tasks across a reload, so the disposing service aborts each
  activation-owned controller, resolves its terminal gate (the
  effect-scoped onTaskDone listener is already gone), and awaits done.
  A new test kills a mid-start activation through HMR disposal.

Subject: [PATCH 341/557] fix: address codex review round 3

- Strict steer additionally requires an OPEN STEP: between steps the
  loop may be awaiting its continuation/turn-stop checkpoints, where
  pending steering was already folded and a terminal stop discards a
  later arrival. A message accepted during an open step is drained and
  recorded at that step's settlement before any terminal decision, so
  the acknowledged-then-discarded window is closed. New keyless test
  holds agent/turn-stop open and pins the rejection.
- tool-subagent-control README: distinguish synchronous not-delivered
  errors from started-Task failures (unknown/foreign/descriptor-less
  ids settle the started Task as failed), and drop the claim that the
  completion notice carries the child's response.

 Every continuable child turn is admitted through this Task-backed path. A non-terminal Task is the only supported live activation; when no activation exists, its run has already been disposed and the durable child is resumable. Before routing any by-id operation, the control service synchronously compares its association with `ctx.agents.get(childId)`. A registry Agent with no association, or a registry Agent different from the associated `run.localAgent`, is an ownership conflict: the control service fails rather than adopting an idle Agent or attaching an untracked turn. When neither exists, cold resume may proceed; a competing publication after that check still loses at the Agent registry collision boundary.
 
-Routing follows the Task association. A running Task accepts live delivery through the run's optional strict `SubagentRun.steer` capability. An absent Task starts a fresh Task and cold-resumes the child. In-process spawn and fork implement this capability with synchronous checks that share one frame with the `Agent.steer()` call: the child must be `running`, its turn must still be open in the log (status stays `running` through a closed turn's durability flush, where the loop strands drained steering), and no structured capture may have committed (its terminal stop makes the loop discard late steering). Providers must not expose the Agent-level idle fallback as strict steering, because that fallback may start an untracked turn after the observed run has ended. If the Task settles between association lookup and this strict check, `steer()` fails, `send_message` reports the message as not delivered, and that call does not fall through to cold resume; a later retry after Task terminal may start the next activation.

 The control service does not serialize two callers that race a stopped child through paths outside it, nor does it model a separate settling phase between result production and disposal. The synchronous association install before the producer's first await admits one activation per child in this process — a competing `sendMessage` during resume load observes the pending activation and fails explicitly — while a bypassing publication still loses at the Agent registry's same-session collision boundary. Delivery racing startup, cancellation, completion, or cleanup may also fail. These limitations are explicit rather than hidden behind a larger lifecycle abstraction.

+`message delivered to running task ` when the message joined the running activation, or `message started task  continuing subagent ` when it started a cold-resume activation. Synchronous routing failures — an ownership conflict, a lost steering race, no live-delivery capability — are errored results whose message states the message was not delivered. An absent activation always reports `started`: lookup runs inside that Task, so an unknown, foreign, or descriptor-less child surfaces as the started Task settling `failed` (read through `task_output`), not as an errored `send_message` result.
 
 #### Token effect

 Every continuable child turn is admitted through this Task-backed path. A non-terminal Task is the only supported live activation; when no activation exists, its run has already been disposed and the durable child is resumable. Before routing any by-id operation, the control service synchronously compares its association with `ctx.agents.get(childId)`. A registry Agent with no association, or a registry Agent different from the associated `run.localAgent`, is an ownership conflict: the control service fails rather than adopting an idle Agent or attaching an untracked turn. When neither exists, cold resume may proceed; a competing publication after that check still loses at the Agent registry collision boundary.
 
-Routing follows the Task association. A running Task accepts live delivery through the run's optional strict `SubagentRun.steer` capability. An absent Task starts a fresh Task and cold-resumes the child. In-process spawn and fork implement this capability with synchronous checks that share one frame with the `Agent.steer()` call: the child must be `running`, its turn must still be open in the log (status stays `running` through a closed turn's durability flush, where the loop strands drained steering), a step must be open (between steps the loop may sit at its continuation/turn-stop checkpoints, where steering was already folded and a terminal stop discards a later arrival), and no structured capture may have committed (its terminal stop makes the loop discard late steering). Providers must not expose the Agent-level idle fallback as strict steering, because that fallback may start an untracked turn after the observed run has ended. If the Task settles between association lookup and this strict check, `steer()` fails, `send_message` reports the message as not delivered, and that call does not fall through to cold resume; a later retry after Task terminal may start the next activation.
+Routing follows the Task association. A running Task accepts live delivery through the run's optional strict `SubagentRun.steer` capability. An absent Task starts a fresh Task and cold-resumes the child. In-process spawn and fork implement this capability with synchronous checks followed by the default Agent loop's optional atomic `trySteer()`: the child must be `running`, its turn and step must still be open in the log, the step's final steering drain must not have begun, and no structured capture may have committed. The loop closes `trySteer()` acceptance before draining and entering `agent/post-step`, so a terminal stop cannot discard an acknowledged message from that window. A loop without `trySteer()` cannot back strict in-process delivery. Providers must not expose the Agent-level idle fallback as strict steering, because that fallback may start an untracked turn after the observed run has ended. If the Task settles between association lookup and this strict operation, `steer()` fails, `send_message` reports the message as not delivered, and that call does not fall through to cold resume; a later retry after Task terminal may start the next activation.
 
 The control service does not serialize two callers that race a stopped child through paths outside it, nor does it model a separate settling phase between result production and disposal. The synchronous association install before the producer's first await admits one activation per child in this process — a competing `sendMessage` during resume load observes the pending activation and fails explicitly — while a bypassing publication still loses at the Agent registry's same-session collision boundary. Delivery racing startup, cancellation, completion, or cleanup may also fail. These limitations are explicit rather than hidden behind a larger lifecycle abstraction.

Your working directory is {{cwd}}.\n\nVerify your work by running the code or tests. Keep answers brief and factual.\n\n\nUse the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.\n\nUse the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.\n\nCheck the [exit code: N] marker on every bash result; investigate failures before moving on.\n\nTrack every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results.

Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.\n\n## Writing code for run_code\n\nPass `run_code` the body of an async TypeScript function (erasable syntax only — no `enum` or namespaces; type annotations are advisory, the code runs type-stripped). Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Independent read-only calls MAY overlap under `Promise.all` (safe calls run concurrently; mutating calls run alone, in submission order). Sequence dependent work with `await`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ntype JsonValue = null | boolean | number | string | JsonValue[] | { [key: string]: JsonValue }\n\ninterface ToolArgsMap {\n  /** Execute a bash command (`bash -c`) and return its stdout/stderr.

This creates an in-memory runtime Plugin, not an installed or configured Plugin. It remains active across later turns until cordis_unmount, toolset unload, or DSH restart. It does not create files, install a package, change cordis.yml or personal/project config, survive restart, or automatically become permanent. To keep it, ask the Agent to implement a normal local, project, or repository Plugin through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime. */\n  cordis_mount: {\n    /** JavaScript body returning a temporary Plugin; evaluated now and saved nowhere. */\n    code: string;\n  } & Record;\n  /** Unmount a current-process temporary Plugin created by cordis_mount.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn. The workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result. Script-body hooks: - `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly. - `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages. - `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`. - `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim. Misused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.

This creates an in-memory runtime Plugin, not an installed or configured Plugin. It remains active across later turns until cordis_unmount, toolset unload, or DSH restart. It does not create files, install a package, change cordis.yml or personal/project config, survive restart, or automatically become permanent. To keep it, ask the Agent to implement a normal local, project, or repository Plugin through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime.","parameters":{"type":"object","properties":{"code":{"type":"string","description":"JavaScript body returning a temporary Plugin; evaluated now and saved nowhere."}},"required":["code"]}},{"name":"cordis_unmount","description":"Unmount a current-process temporary Plugin created by cordis_mount.

An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together).

Your working directory is {{cwd}}.\n\nVerify your work by running the code or tests. Keep answers brief and factual.\n\n\nUse the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.\n\nUse the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true.

Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Independent read-only calls MAY overlap under `Promise.all` (safe calls run concurrently; mutating calls run alone, in submission order). Sequence dependent work with `await`.\n- Emit results with `return` and/or `console.log(...)`.

Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn. The workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result. Script-body hooks: - `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly. - `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages. - `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`. - `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim. Misused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`. Constraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn.\n\nThe workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise` — run one subagent to completion.

Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

Your working directory is {{cwd}}.\n\nVerify your work by running the code or tests. Keep answers brief and factual.\n\n\nUse the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.\n\nUse the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.\n\nCheck the [exit code: N] marker on every bash result; investigate failures before moving on.\n\nTrack every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.\n\nUse the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.\n\n## Writing code for run_code\n\nPass `run_code` the body of an async TypeScript function (erasable syntax only — no `enum` or namespaces; type annotations are advisory, the code runs type-stripped). Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Independent read-only calls MAY overlap under `Promise.all` (safe calls run concurrently; mutating calls run alone, in submission order). Sequence dependent work with `await`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ntype JsonValue = null | boolean | number | string | JsonValue[] | { [key: string]: JsonValue }\n\ninterface ToolArgsMap {\n  /** Execute a bash command (`bash -c`) and return its stdout/stderr.

It does not create files, install a package, change cordis.yml or personal/project config, survive restart, or automatically become permanent. To keep it, ask the Agent to implement a normal local, project, or repository Plugin through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime. */\n  cordis_mount: {\n    /** JavaScript body returning a temporary Plugin; evaluated now and saved nowhere. */\n    code: string;\n  } & Record;\n  /** Unmount a current-process temporary Plugin created by cordis_mount.

This creates an in-memory runtime Plugin, not an installed or configured Plugin. It remains active across later turns until cordis_unmount, toolset unload, or DSH restart. It does not create files, install a package, change cordis.yml or personal/project config, survive restart, or automatically become permanent. To keep it, ask the Agent to implement a normal local, project, or repository Plugin through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime.","parameters":{"type":"object","properties":{"code":{"type":"string","description":"JavaScript body returning a temporary Plugin; evaluated now and saved nowhere."}},"required":["code"]}},{"name":"cordis_unmount","description":"Unmount a current-process temporary Plugin created by cordis_mount.

Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.\n\nUse the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.\n\n## Writing code for run_code\n\nPass `run_code` the body of an async TypeScript function (erasable syntax only — no `enum` or namespaces; type annotations are advisory, the code runs type-stripped). Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Independent read-only calls MAY overlap under `Promise.all` (safe calls run concurrently; mutating calls run alone, in submission order). Sequence dependent work with `await`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ntype JsonValue = null | boolean | number | string | JsonValue[] | { [key: string]: JsonValue }\n\ninterface ToolArgsMap {\n  /** Execute a bash command (`bash -c`) and return its stdout/stderr.

It does not create files, install a package, change cordis.yml or personal/project config, survive restart, or automatically become permanent. To keep it, ask the Agent to implement a normal local, project, or repository Plugin through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime. */\n  cordis_mount: {\n    /** JavaScript body returning a temporary Plugin; evaluated now and saved nowhere. */\n    code: string;\n  } & Record;\n  /** Unmount a current-process temporary Plugin created by cordis_mount.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn. The workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result. Script-body hooks: - `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly. - `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages. - `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`. - `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim. Misused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`. Constraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn.\n\nThe workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise` — run one subagent to completion.

Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

Your working directory is {{cwd}}.\n\nVerify your work by running the code or tests. Keep answers brief and factual.\n\n\nUse the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.\n\nUse the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.\n\nCheck the [exit code: N] marker on every bash result; investigate failures before moving on.\n\nTrack every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.\n\nUse the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.\n\n## Writing code for run_code\n\nPass `run_code` the body of an async TypeScript function (erasable syntax only — no `enum` or namespaces; type annotations are advisory, the code runs type-stripped). Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Independent read-only calls MAY overlap under `Promise.all` (safe calls run concurrently; mutating calls run alone, in submission order). Sequence dependent work with `await`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ntype JsonValue = null | boolean | number | string | JsonValue[] | { [key: string]: JsonValue }\n\ninterface ToolArgsMap {\n  /** Execute a bash command (`bash -c`) and return its stdout/stderr.

This creates an in-memory runtime Plugin, not an installed or configured Plugin. It remains active across later turns until cordis_unmount, toolset unload, or DSH restart. It does not create files, install a package, change cordis.yml or personal/project config, survive restart, or automatically become permanent. To keep it, ask the Agent to implement a normal local, project, or repository Plugin through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime.","parameters":{"type":"object","properties":{"code":{"type":"string","description":"JavaScript body returning a temporary Plugin; evaluated now and saved nowhere."}},"required":["code"]}},{"name":"cordis_unmount","description":"Unmount a current-process temporary Plugin created by cordis_mount.

+{"type":"request/header","seq":4,"time":1783957884486,"data":{"header":{"config":{"provider":"deepseek-official","model":"deepseek-v4-flash"},"system":"You are an AI agent powered by the DeepSeek Harness SDK.\n\nYou are headless-agent, a coding assistant powered by the deepseek-v4-flash model. Your working directory is {{cwd}}.\n\nVerify your work by running the code or tests. Keep answers brief and factual.\n\n\nUse the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.\n\nUse the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.\n\nCheck the [exit code: N] marker on every bash result; investigate failures before moving on.\n\nTrack every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.\n\nUse the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.\n\n## Writing code for run_code\n\nPass `run_code` the body of an async TypeScript function (erasable syntax only — no `enum` or namespaces; type annotations are advisory, the code runs type-stripped). Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Independent read-only calls MAY overlap under `Promise.all` (safe calls run concurrently; mutating calls run alone, in submission order). Sequence dependent work with `await`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ntype JsonValue = null | boolean | number | string | JsonValue[] | { [key: string]: JsonValue }\n\ninterface ToolArgsMap {\n  /** Execute a bash command (`bash -c`) and return its stdout/stderr.

This creates an in-memory runtime Plugin, not an installed or configured Plugin. It remains active across later turns until cordis_unmount, toolset unload, or DSH restart. It does not create files, install a package, change cordis.yml or personal/project config, survive restart, or automatically become permanent. To keep it, ask the Agent to implement a normal local, project, or repository Plugin through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime. */\n  cordis_mount: {\n    /** JavaScript body returning a temporary Plugin; evaluated now and saved nowhere. */\n    code: string;\n  } & Record;\n  /** Unmount a current-process temporary Plugin created by cordis_mount.

This creates an in-memory runtime Plugin, not an installed or configured Plugin. It remains active across later turns until cordis_unmount, toolset unload, or DSH restart. It does not create files, install a package, change cordis.yml or personal/project config, survive restart, or automatically become permanent. To keep it, ask the Agent to implement a normal local, project, or repository Plugin through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime.","parameters":{"type":"object","properties":{"code":{"type":"string","description":"JavaScript body returning a temporary Plugin; evaluated now and saved nowhere."}},"required":["code"]}},{"name":"cordis_unmount","description":"Unmount a current-process temporary Plugin created by cordis_mount.

Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

Keep answers brief and\nfactual.\n\n\nUse the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.\n\nUse the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.\n\nCheck the [exit code: N] marker on every bash result; investigate failures before moving on.\n\nUse a terminal session only when work needs persistent terminal state or interactive stdin; prefer bash/read/write/edit for bounded one-shot operations. Track every terminal session id and close sessions that no longer matter. An inferred_idle or timeout result does not prove the foreground command exited.\n\nTrack every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.\n\nUse the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution.

@@ -65,6 +65,7 @@ The handle every plugin programs against:
 - `agent.updateInbox(itemId, action)` — synchronously edits or removes one still-pending queued occurrence. Edit keeps its `MessageId`, `InboxItemId`, source, and FIFO position while replacing frozen content; remove emits the occurrence's terminal discard. Steering and claimed occurrences return `not-found`.
 - `agent.followup(input)` — the `next-turn`/wakeup preset of `send()`: queue an ordinary follow-up turn and wake the driver.
 - `agent.steer(input)` — the `next-step`/wakeup preset: during prompt admission or an open turn, stage steering for the next safe boundary without dispatching `agent/prompt-submit`; outside that acceptance window, delegate to a woken follow-up. Admission failure leaves staged steering for retry or a later admitted prompt, while cancellation or disposal may discard it.
+- `agent.trySteer?(input)` — an optional strict-steering capability implemented by the default loop. It atomically submits an identified message only while the current step still owns its final drain, returning `false` without accepting input during admission, between steps, or after that drain begins; cancellation and disposal can still discard accepted steering.
 - `agent.inject(input)` — the `next-step`/no-wakeup preset: append model-facing context without running the model; the next request sees a verbatim user-role message whose provenance is carried by the required `input.source`. During prompt admission or an open turn, injection waits in the outbox for the next safe boundary. Outside that acceptance window, it appends immediately without opening a turn; a context-only admission batch takes this fallback if admission closes without a turn, while context staged beside steering remains pending with it. Persistence reacts to `session/event` independently. Injection emits no `agent/inbox/*` event.
 - `agent.acceptsNextStep` — whether a `next-step` send would currently join prompt admission or the open turn. Use this narrower routing predicate when a caller must choose between steering and a fresh admitted prompt; `status === 'running'` also covers admission exit and turn settlement.
 - `agent.cancel(cause, options?)` — cancel the active turn and, unless `options.keepInbox`, ALL pending work. Callers must choose the `user | parent` cause explicitly; an active holder copies its discriminant into a detached frozen signal reason before aborting. An effective call emits `agent/cancel-requested` with the cause before clearing queued and steering work; dropped items are reported on `agent/inbox/discard`, and observers may synchronize state but cannot veto cancellation. `keepInbox: true` aborts the turn but preserves queued and steering items (no discard, and un-started work is not dropped). The same-process typed seam adds no runtime validation or compatibility fallback for untyped callers. Repeated active-turn cancellation is first-wins for the signal, and idle cancellation is a safe no-op with no notification. ACP maps to `user`, while in-process parent propagation maps to `parent`. The cause is runtime-only; durable `turn/end` stays coarse `aborted`.

+The initial background delegation asks the control service to start the child and register its Task. A continuable provider confirms the activation's final session state durable before fulfilling a successful run result. Task settlement awaits that result, calls `run.dispose()` (through the control service's `settleRun`), and only then records the `TaskOutcome`; `task_kill` aborts the active run, whose settlement path still disposes it. A terminal Task therefore leaves the durable child session but no live child Agent. A failed required durability checkpoint rejects the run with stable code `DURABILITY_FAILED` and the backend failure as its cause; the control service records a failed Task whose detail explains that the latest state was not confirmed persisted and may be unavailable or stale on resume.
 
 Every later turn creates another Task. Its producer resources cover only that activation, never the child session. It reaches one terminal status, has one result, and is never reopened. The exact live parent Agent remains the Task registry owner: disposing that instance cancels, awaits, and removes its Tasks. Task APIs authorize a caller whose session id matches that owner, but a same-id replacement does not become the notification or teardown target. This preserves the `settleRun()` contract and bounds Task-owned live children by concurrent work rather than historical session count.

 `SubagentControlService`'s resume path loads the known child session, folds its descriptor, authorizes the persisted `parentSession`, and runs inside the Task it creates. It passes a fully resolved request, including the Task-owned cancellation signal, to the low-level `SubagentService.resume(provider, request)`, whose only responsibility is capability-checked provider dispatch and the ordinary run lifecycle observation used by `start`. The selected `SubagentProvider.resume?()` owns transport-specific reconstruction (in-process: `parent.ctx.agents.resume` under the currently loaded parent scope) and returns a fresh run. Presence of the provider method is the continuation capability, so no redundant capability flag exists. `SubagentControlService.sendMessage()` chooses between the associated run's `steer?()` operation and this cold-resume path. Neither the low-level service nor a provider enumerates durable children or associates Tasks.
 
-The background tool validates and snapshots descriptor inputs before calling `TaskService.start()`. A synchronous validation failure rejects the tool call and creates no Task. The tool otherwise returns the child and Task ids immediately, without waiting for child publication or descriptor durability. Child creation, first-turn persistence, or descriptor persistence failure disposes any published run and settles the already-created Task as `failed`; the model observes that failure through the ordinary Task completion or `task_output` path. In-process spawn and fork reconstruct composition under the currently loaded parent scope. A fork resume loads the child's own persisted transcript, which already contains the completed-turn prefix captured at initial creation; it never forks the parent's newer history again. Resuming a parent does not eagerly resume its children.

The tool otherwise returns the child and Task ids immediately, without waiting for child publication or descriptor durability. In-process continuable providers perform a final session flush after the child becomes idle and before reading the result; this retries a failed loop checkpoint while the child is still live. If the final confirmation fails, the provider rejects instead of returning unconfirmed output, the control service disposes the run, and the already-created Task settles as `failed` with the durability diagnosis in its detail.

 TODO (ACP continuation): persist the remote ACP session id as provider-specific descriptor data and implement `AcpProvider.resume?()` as spawn, initialize, `loadSession`, then prompt. The initial ACP run must verify `initialize.agentCapabilities.loadSession`, and every resumed process must use the same durable backend; replayed history from `loadSession` must not be collected as the new activation's output. Because ACP load support is negotiated per child rather than established solely by the provider method's presence, this follow-up must also define how a start result advertises child-specific continuation before ACP children enter the durable catalog.

 - Driving a continuable child through the ordinary Agent API bypasses its Task association. The control service rejects that live child as an ownership conflict; adapters must display persisted transcripts without loading an Agent and submit human input through `SubagentControlService.sendMessage()`.
 - The active-run association coordinates only one runtime. Concurrent resume from multiple processes is not serialized; that deployment requires a persistence-level lease or compare-and-set operation.
 - Human interaction requires the exact parent Agent instance to remain live because owner disposal cancels and removes its Tasks. It also requires an attached Task control surface. Standalone child interaction requires a future separation between Task access ownership and durable notification targeting.

 ## Activation lifecycle
 
-A continuable background subagent is a durable child session with a series of Task-backed activations. `startContinuable()` allocates the stable child session id before Task creation, snapshots the descriptor inputs (a non-JSON input throws with no Task), and registers the initial activation's Task; the provider publishes exactly that child id and appends the versioned `subagent/descriptor` event inside the child's first turn. Every activation — initial or resumed — creates a fresh Task whose settlement awaits the child result, disposes the run, and only then records the `TaskOutcome`: a terminal Task leaves the durable child session but no live child Agent.
+A continuable background subagent is a durable child session with a series of Task-backed activations. `startContinuable()` allocates the stable child session id before Task creation, snapshots the descriptor inputs (a non-JSON input throws with no Task), and registers the initial activation's Task; the provider publishes exactly that child id and appends the versioned `subagent/descriptor` event inside the child's first turn. Every activation — initial or resumed — creates a fresh Task whose settlement awaits the provider's durability-confirmed child result, disposes the run, and only then records the `TaskOutcome`: a terminal Task leaves the durable child session but no live child Agent. A provider rejection with `DURABILITY_FAILED` settles the Task as `failed` and copies the error message into `detail`, so `task_output` reports the failed checkpoint and resumability risk without exposing unconfirmed output.
 
 `sendMessage(parent, childId, message)` owns steer-or-resume routing. A running activation receives live delivery through the run's strict `steer` capability and returns the existing Task id (`steered`); an absent activation starts a fresh Task that loads the persisted child, authorizes the recorded `parentSession` as the direct parent, folds the descriptor, and dispatches `SubagentService.resume()` (`started`). Failure throws and means the message was not delivered: losing a strict-steering race with Task settlement never falls through to cold resume within the same call, and a live registry Agent outside the activation association is an ownership conflict rather than an adoption target.

 After fulfillment, the caller owns the run. Provider-plugin unload does not revoke it. `dispose()` removes the live abort listener, records cancellation, and delegates to the returned `AgentHandle.dispose()`, whose memoized quiescence transaction stops the loop, removes the agent and session, and unwinds scoped registrations. Cancellation owns every non-completed in-flight outcome and reports `aborted`; an already-completed turn remains completed.
 
-Runs expose the strict `steer` capability: the synchronous checks and the `Agent.steer()` call share one frame, so delivery joins the observed turn or throws. Delivery requires `AgentStatus.running`, an open turn in the child log (status stays `running` through a closed turn's durability flush, where the loop would strand the message), an open step (between steps the loop may sit at its continuation/turn-stop checkpoints, where steering was already folded and a terminal stop discards a later arrival; a message accepted during an open step is recorded at that step's settlement before any terminal decision), and no committed structured capture (whose terminal stop makes the loop discard late steering). The Agent-level idle fallback (queue and start a new turn) is deliberately not reachable through the run — that would start an untracked turn after the run's result was read.

Child-level failures resolve with a non-`completed` reason; only an infrastructure fault that the seam cannot represent may reject. For a continuable activation, a completed result also confirms that the provider made its final state durable; a failed required checkpoint rejects as infrastructure rather than publishing unconfirmed output. `dispose()` is idempotent, cancels remaining work, and waits for the child resources to quiesce.
 
 A local run publishes an ordinary child agent/session before `start()` fulfills, returns that shared session id as `SubagentRun.id`, exposes the exact child as `SubagentRun.localAgent`, and records `request.parent.session.id` in the child's `parentSession` header. A continuable start publishes exactly the control-allocated `continuation.sessionId`. Remote providers instead mint a parent-scoped lifecycle id and return `localAgent: undefined`.

Continuable-child orchestration lives on `ctx.subagentControl` in [dsh-subagent-control](../../packages/subagent/subagent-control).

-A **continuable background subagent** is a durable child session with a series of Task-backed activations. `ctx.subagentControl` (`SubagentControlService` in [dsh-subagent-control](../../packages/subagent/subagent-control)) allocates the stable child id, snapshots the versioned `subagent/descriptor` payload, and passes both through the resolved start request; the provider publishes exactly that id and appends the descriptor inside the child's first turn.

 A continuable background subagent is a durable child session with a series of Task-backed activations. `startContinuable()` allocates the stable child session id before Task creation, snapshots the descriptor inputs (a non-JSON input throws with no Task), and registers the initial activation's Task; the provider publishes exactly that child id and appends the versioned `subagent/descriptor` event inside the child's first turn. Every activation — initial or resumed — creates a fresh Task whose settlement awaits the provider's durability-confirmed child result, disposes the run, and only then records the `TaskOutcome`: a terminal Task leaves the durable child session but no live child Agent. A provider rejection with `DURABILITY_FAILED` settles the Task as `failed` and copies the error message into `detail`, so `task_output` reports the failed checkpoint and resumability risk without exposing unconfirmed output.
 
-`sendMessage(parent, childId, message)` owns steer-or-resume routing. A running activation receives live delivery through the run's strict `steer` capability and returns the existing Task id (`steered`); an absent activation starts a fresh Task that loads the persisted child, authorizes the recorded `parentSession` as the direct parent, folds the descriptor, and dispatches `SubagentService.resume()` (`started`). Failure throws and means the message was not delivered: losing a strict-steering race with Task settlement never falls through to cold resume within the same call, and a live registry Agent outside the activation association is an ownership conflict rather than an adoption target.
+`sendMessage(parent, childId, message, source)` owns steer-or-resume routing and requires the caller's `MessageSource`. A running activation preserves it through the run's strict `steer` capability and returns the existing Task id (`steered`); an absent activation starts a fresh Task that loads the persisted child, authorizes the recorded `parentSession` as the direct parent, folds the descriptor, and dispatches `SubagentService.resume()` with the same source (`started`). Either route projects the content to the model as a user-role message while retaining its source in the child log. Failure throws and means the message was not delivered: losing a strict-steering race with Task settlement never falls through to cold resume within the same call, and a live registry Agent outside the activation association is an ownership conflict rather than an adoption target.
 
 Cancellation targets the whole activation. `task_kill` or owner disposal aborts the Task-owned signal; before publication the provider rejects only after its creation transaction rolled back to quiescence, afterwards the signal cancels the published run, and settlement records `killed` only once the activation is quiescent. Human input shares this path: an adapter submits child input through `sendMessage()` under the loaded parent, so parent and human messages that joined one turn share its result and cancellation outcome, and `TaskService.start()`'s control-surface requirement applies (load `@deepseek-ai/dsh-tool-tasks` or attach a surface).

 Every continuable child turn is admitted through this Task-backed path. A non-terminal Task is the only supported live activation; when no activation exists, its run has already been disposed and the durable child is resumable. Before routing any by-id operation, the control service synchronously compares its association with `ctx.agents.get(childId)`. A registry Agent with no association, or a registry Agent different from the associated `run.localAgent`, is an ownership conflict: the control service fails rather than adopting an idle Agent or attaching an untracked turn. When neither exists, cold resume may proceed; a competing publication after that check still loses at the Agent registry collision boundary.
 
-Routing follows the Task association. A running Task accepts live delivery through the run's optional strict `SubagentRun.steer` capability. An absent Task starts a fresh Task and cold-resumes the child. In-process spawn and fork implement this capability with synchronous checks followed by the default Agent loop's optional atomic `trySteer()`: the child must be `running`, its turn and step must still be open in the log, the step's final steering drain must not have begun, and no structured capture may have committed. The loop closes `trySteer()` acceptance before draining and entering `agent/post-step`, so a terminal stop cannot discard an acknowledged message from that window. A loop without `trySteer()` cannot back strict in-process delivery. Providers must not expose the Agent-level idle fallback as strict steering, because that fallback may start an untracked turn after the observed run has ended. If the Task settles between association lookup and this strict operation, `steer()` fails, `send_message` reports the message as not delivered, and that call does not fall through to cold resume; a later retry after Task terminal may start the next activation.
+Routing follows the Task association. A running Task accepts live delivery through the run's optional confirmed `SubagentRun.steer` capability. An absent Task starts a fresh Task and cold-resumes the child. In-process spawn and fork first synchronously require the child to be `running` and reject an already committed structured capture, then call `Agent.steer()` and await that exact message's admission receipt. The default loop gives every steering item a message-owned receipt and resolves it `admitted` only after a successful pre-step has appended the message, captured the immutable request history, and committed `step/start`; terminal turn policy, cancellation, and disposal resolve pending receipts `rejected`. A non-terminal turn close may carry pending steering into a later queued turn without acknowledging it. Providers must check the live status before `Agent.steer()` so its idle path cannot start a turn outside the observed run. If Task settlement or terminal policy wins after association lookup but before request admission, `steer()` rejects, `send_message` reports the message as not delivered, and that call does not fall through to cold resume; a later retry after Task terminal may start the next activation.
 
 The control service does not serialize two callers that race a stopped child through paths outside it, nor does it model a separate settling phase between result production and disposal. The synchronous association install before the producer's first await admits one activation per child in this process — a competing `sendMessage` during resume load observes the pending activation and fails explicitly — while a bypassing publication still loses at the Agent registry's same-session collision boundary. Delivery racing startup, cancellation, completion, or cleanup may also fail. These limitations are explicit rather than hidden behind a larger lifecycle abstraction.

 The versioned descriptor (`SUBAGENT_DESCRIPTOR_VERSION` in [descriptor.ts](../../../../packages/subagent/subagent/src/descriptor.ts)) contains the subagent provider name, resolved child `agentOptions.provider` and `agentOptions.model`, and optional `persona` and `toolFilter`. It does not snapshot the merge-extensible `AgentOptions` object: unrelated extension values cannot make continuation fail merely because they are not JSON. It deliberately omits `subagentDepth`; cold resume relies on the persisted header's `delegationDepth` rather than reconstructing depth from the descriptor. `outputSchema` belongs to one activation's result contract rather than durable child composition. The child header remains authoritative for the child id, `cwd`, `parentSession`, `seedLength`, and `delegationDepth`, while the persisted child transcript owns the fork seed and subsequent history. [`delegationDepthOf()`](../../../../packages/subagent/subagent/src/index.ts) takes the maximum of header and runtime values, so reconstructed runtime options may deepen the persisted value but never lower it and a resumed child cannot regain a top-level delegation budget.
 
-Cold resume cannot depend on an optional method of the old `SubagentRun`, because that run has been disposed and is not retained across process restart. `SubagentRun` has no `resume` operation: a run represents one disposable activation and exposes only activation-scoped operations. The former `SubagentRun.sendMessage?()` capability is named `SubagentRun.steer?()` so its strict live-only contract cannot be confused with service orchestration or the model-facing tool.

 `SubagentControlService`'s resume path loads the known child session, folds its descriptor, authorizes the persisted `parentSession`, and runs inside the Task it creates. It passes a fully resolved request, including the Task-owned cancellation signal, to the low-level `SubagentService.resume(provider, request)`, whose only responsibility is capability-checked provider dispatch and the ordinary run lifecycle observation used by `start`. The selected `SubagentProvider.resume?()` owns transport-specific reconstruction (in-process: `parent.ctx.agents.resume` under the currently loaded parent scope) and returns a fresh run. Presence of the provider method is the continuation capability, so no redundant capability flag exists. `SubagentControlService.sendMessage()` chooses between the associated run's `steer?()` operation and this cold-resume path. Neither the low-level service nor a provider enumerates durable children or associates Tasks.

+Admission-time and active-turn `inject()` stage for the next step; tool-time injection and post-tool `additionalContexts` settle after results. Steering shares the outbox but remains provisional until a request admits it. `steer()` returns a message-owned receipt: after `agent/step` and asynchronous prompt assembly succeed, the loop commits the stable batch, snapshots request history, opens `step/start`, then resolves its receipts as admitted with the turn and step; later arrivals wait. A turn-concluding tool result, broad cancellation, disposal, or a claimed idle-steering turn that never opens a step rejects affected receipts, while `cancel(..., { keepInbox: true })` and non-terminal routing preserve pending delivery. Idle `inject()` appends immediately without changing turn numbers; persistence drains eagerly.
 
 Pruning precedes summaries; overflow retries require durable progress. `agent/request-error` may authorize one retry turn between failed-step and turn close; cancellation wins.

 The unified `send()` primitive routes content and source by (`target` × `wakeup`); `followup`/`steer`/`inject` are its fixed-preset aliases. A `next-turn` item joins the queued FIFO, waking the driver unless `wakeup: false`; admission happens before any turn opens. `reserveTurnAdmission()` can synchronously hold that idle boundary for a standalone durable operation: accepted waking work has right of way, later sends keep their ordinary queue identity and FIFO position, release re-arms the same driver path, and `whenIdle()` waits for the reservation without making teardown await it. The loop opens a private next-step acceptance window before `agent/prompt-submit` and closes it before `turn/end`. During that window, `steer()` and `inject()` stage in one outbox; an allowed admission opens the turn, records the prompt and returned `additionalContexts`, then drains the staged input before the first request. A blocked or failed admission writes no prompt or hook-produced context. A caller-staged context-only batch then takes idle injection's immediate append, while steering and context staged beside it remain pending for retry or a later admitted prompt. Outside the window, steering becomes a waking queued prompt and injection immediately appends `user/message` without opening a turn or running the model.
 
+`steer()` attaches a one-shot admission receipt to its exact accepted message. After `agent/step` and asynchronous prompt assembly succeed, the loop commits a stable pending batch as `steering/message`, snapshots derived history, and opens `step/start`; only then does each receipt resolve `admitted` with that turn and step. Later arrivals remain pending. Idle steering enters the ordinary FIFO and uses the first request of its eventual turn as the same admission boundary. A turn-concluding tool result, broad cancellation, disposal, or a claimed idle-steering turn that never reaches a request resolves affected receipts `rejected`; `cancel(..., { keepInbox: true })` and non-terminal routing preserve pending delivery. Open-turn `inject()` still commits after all tool results, including accepted context finalized during an interrupted batch, while steering remains provisional until a request admits it.
+
 Every FIFO acceptance mints an `InboxItemId` and publishes `agent/inbox/enqueue` with the complete occurrence. `updateInbox()` owns the synchronous queued-item boundary: edit freezes replacement content without changing message identity or position, while remove publishes discard. Edit publishes `agent/inbox/update`; steering and claimed occurrences return `not-found`. Claim publishes `agent/inbox/dequeue` and irrevocably removes the live address before prompt admission, so a racing update cannot rewrite durable history; `cancel()` without `keepInbox` publishes `agent/inbox/discard`.

 统一的 `send()` 原语按（`target` × `wakeup`）路由内容与来源；`followup`/`steer`/`inject` 是它的固定预设别名。`next-turn` 项加入排队 FIFO，除非 `wakeup: false`，否则会唤醒驱动器；接纳发生在任何轮次开启之前。`reserveTurnAdmission()` 可以为独立持久操作同步保留该空闲边界：已获接纳的唤醒工作拥有优先权，之后发送的项保留普通队列身份与 FIFO 位置，释放会重新启用同一驱动器路径，`whenIdle()` 会等待预留结束，但 teardown 不会等待它。循环在 `agent/prompt-submit` 之前打开一个私有的 next-step 接收窗口，并在 `turn/end` 之前关闭它。在该窗口内，`steer()` 与 `inject()` 会暂存到同一个 outbox；接纳获准后会开启轮次，记录提示词及其返回的 `additionalContexts`，再于首次请求前排空暂存输入。接纳被阻止或失败时，不会写入提示词或钩子生成的上下文。之后，仅含调用方暂存上下文的批次会采用空闲注入的立即追加行为，而 steering（中途引导）及与其一同暂存的上下文则继续待处理，以供重试或之后获准的提示词使用。窗口之外，steering 会成为唤醒驱动器的排队提示词，而注入会立即追加 `user/message`，不开启轮次也不运行模型。
 
+`steer()` 会把一次性准入回执附着到其准确的已接收消息。`agent/step` 和异步提示词组装成功后，循环把稳定的待处理批次提交为 `steering/message`、捕获派生历史并开启 `step/start`；只有此时，每个回执才会解析为 `admitted`，并附带轮次与步骤。之后到达的消息继续待处理。空闲 steering 会进入普通 FIFO，并以其最终轮次的首次请求作为相同准入边界。结束轮次的工具结果、广义取消、dispose（资源释放），或已领取 idle-steering 消息却从未到达请求的轮次，会把受影响回执解析为 `rejected`；`cancel(..., { keepInbox: true })` 和非终止型路由会保留待处理投递。活跃轮次内的 `inject()` 仍会在所有工具结果后提交，包括被中断批次中已最终确认的上下文；steering 则保持待准入，直到请求接纳它。
+
 每次 FIFO 接受项时都会铸造一个 `InboxItemId`，并通过 `agent/inbox/enqueue` 发布完整的单次入队项。`updateInbox()` 持有同步 queued 项边界：编辑会冻结替换内容，但不改变消息标识或位置；移除会发布 discard。编辑会发布 `agent/inbox/update`；steering 项和已被认领的项会返回 `not-found`。认领操作会发布 `agent/inbox/dequeue`，并在提示词接纳前不可逆地移除实时寻址标识，因此竞态中的更新无法改写持久历史；`cancel()` 在不带 `keepInbox` 时会发布 `agent/inbox/discard`。

@@ -64,8 +64,7 @@ The handle every plugin programs against:
 - `agent.reserveTurnAdmission()` — synchronously reserve the idle boundary before any queued waking prompt can claim its turn. An accepted prompt, including a same-tick pending wake, has right of way and makes reservation return `undefined`. Later sends keep their ordinary IDs, FIFO placement, and wakeup facts while held; `acceptsNextStep` remains false, `inject()` is not withheld, `whenIdle()` counts the reservation as activity, and the returned release is idempotent. This narrow coordination capability lets standalone durable operations such as manual compaction finish and flush before queued prompts derive from the session.
 - `agent.updateInbox(itemId, action)` — synchronously edits or removes one still-pending queued occurrence. Edit keeps its `MessageId`, `InboxItemId`, source, and FIFO position while replacing frozen content; remove emits the occurrence's terminal discard. Steering and claimed occurrences return `not-found`.
 - `agent.followup(input)` — the `next-turn`/wakeup preset of `send()`: queue an ordinary follow-up turn and wake the driver.
-- `agent.steer(input)` — the `next-step`/wakeup preset: during prompt admission or an open turn, stage steering for the next safe boundary without dispatching `agent/prompt-submit`; outside that acceptance window, delegate to a woken follow-up. Admission failure leaves staged steering for retry or a later admitted prompt, while cancellation or disposal may discard it.
-- `agent.trySteer?(input)` — an optional strict-steering capability implemented by the default loop. It atomically submits an identified message only while the current step still owns its final drain, returning `false` without accepting input during admission, between steps, or after that drain begins; cancellation and disposal can still discard accepted steering.
+- `agent.steer(input)` — the `next-step`/wakeup preset: submit one identified message and receive its `SteeringReceipt`. During prompt admission or an open turn, the message stages for the next safe request boundary without dispatching `agent/prompt-submit`; outside that acceptance window, it becomes a woken queued prompt. `receipt.outcome` resolves `admitted` with the turn and step only after the loop logs the message, captures it in immutable request history, and commits `step/start`. A turn-concluding tool result, broad cancellation, disposal, or pre-admission failure resolves it `rejected`; `cancel(..., { keepInbox: true })` and non-terminal routing preserve pending delivery. Reliable callers await the receipt, while best-effort UI steering may ignore it.
 - `agent.inject(input)` — the `next-step`/no-wakeup preset: append model-facing context without running the model; the next request sees a verbatim user-role message whose provenance is carried by the required `input.source`. During prompt admission or an open turn, injection waits in the outbox for the next safe boundary. Outside that acceptance window, it appends immediately without opening a turn; a context-only admission batch takes this fallback if admission closes without a turn, while context staged beside steering remains pending with it. Persistence reacts to `session/event` independently. Injection emits no `agent/inbox/*` event.
 - `agent.acceptsNextStep` — whether a `next-step` send would currently join prompt admission or the open turn. Use this narrower routing predicate when a caller must choose between steering and a fresh admitted prompt; `status === 'running'` also covers admission exit and turn settlement.
 - `agent.cancel(cause, options?)` — cancel the active turn and, unless `options.keepInbox`, ALL pending work. Callers must choose the `user | parent` cause explicitly; an active holder copies its discriminant into a detached frozen signal reason before aborting. An effective call emits `agent/cancel-requested` with the cause before clearing queued and steering work; dropped items are reported on `agent/inbox/discard`, and observers may synchronize state but cannot veto cancellation. `keepInbox: true` aborts the turn but preserves queued and steering items (no discard, and un-started work is not dropped). The same-process typed seam adds no runtime validation or compatibility fallback for untyped callers. Repeated active-turn cancellation is first-wins for the signal, and idle cancellation is a safe no-op with no notification. ACP maps to `user`, while in-process parent propagation maps to `parent`. The cause is runtime-only; durable `turn/end` stays coarse `aborted`.

 - `agent.reserveTurnAdmission()`：在任何已排队唤醒提示词认领其轮次之前，同步预留空闲边界。已获接纳的提示词拥有优先权，包括同一 tick 内仍在等待唤醒的项，此时预留返回 `undefined`。预留期间，之后发送的项保留其普通 ID、FIFO 位置与唤醒信息；`acceptsNextStep` 保持 false，`inject()` 不受阻塞，`whenIdle()` 将该预留计为活动，返回的释放函数可幂等调用。这项范围有限的协调能力使手动压缩（compaction）等独立持久操作能够在排队提示词从会话派生内容前完成并 flush。
 - `agent.updateInbox(itemId, action)`：同步编辑或移除一个仍处于待处理状态的 queued 入队项。编辑会替换已冻结的内容，同时保留其 `MessageId`、`InboxItemId`、来源与 FIFO 位置；移除会发出该项的终态 discard。steering 项和已被认领的项会返回 `not-found`。
 - `agent.followup(input)`：`send()` 的 `next-turn`／wakeup 预设：排队一个普通后续轮次并唤醒驱动器。
-- `agent.steer(input)`：`next-step`／wakeup 预设：提示词接纳期间或轮次打开时，为下一个安全边界暂存 steering，且不分发 `agent/prompt-submit`；该接收窗口之外则委托给会唤醒的后续轮次。接纳失败会保留暂存的 steering，以供重试或之后获准的提示词使用，而取消或 dispose 可能丢弃它。
+- `agent.steer(input)`：`next-step`／wakeup 预设：提交一条已有标识的消息，并取得其 `SteeringReceipt`。提示词接纳期间或轮次打开时，消息会为下一个安全请求边界暂存，且不分发 `agent/prompt-submit`；该接收窗口之外则成为会唤醒驱动器的排队提示词。只有循环记录消息、将其捕获到不可变请求历史并提交 `step/start` 后，`receipt.outcome` 才会解析为 `admitted`，并附带轮次与步骤。结束轮次的工具结果、广义取消、dispose（资源释放）或准入前故障会使其解析为 `rejected`；`cancel(..., { keepInbox: true })` 和非终止型路由会保留待处理投递。需要可靠投递的调用方应等待回执；尽力执行的 UI steering 可以忽略它。
 - `agent.inject(input)`：`next-step`／不唤醒预设：追加面向模型的上下文而不运行模型；下一次请求会看到一条逐字的 user role 消息，其来源由必填的 `input.source` 携带。提示词接纳期间或轮次打开时，注入会在 outbox 中等待下一个安全边界。该接收窗口之外，它会立即追加而不开启轮次；如果接纳结束却未开启轮次，仅含上下文的接纳批次会采用这一回退，而与 steering 一同暂存的上下文则会随其继续待处理。持久化独立地响应 `session/event`。注入不发出 `agent/inbox/*` 事件。
 - `agent.acceptsNextStep`：当前发送 `next-step` 时，是否会加入提示词接纳或已打开的轮次。当调用方必须在 steering 与新接纳的提示词之间选择时，应使用这一更窄的路由判定；`status === 'running'` 还涵盖接纳收尾与轮次结算阶段。
 - `agent.cancel(cause, options?)`：取消活动轮次，并在未设置 `options.keepInbox` 时取消全部待处理工作。调用方必须显式选择 `user | parent` 原因；活动持有者会在中止前把其判别字段复制为已分离、冻结的信号原因。有效调用会在清除排队与 steering 工作前，随原因发出 `agent/cancel-requested`；丢弃项在 `agent/inbox/discard` 上报告，观察方可以同步状态，但不能 veto 取消。`keepInbox: true` 会中止轮次，但保留排队与 steering 项（不丢弃，且不删除尚未开始的工作）。同进程类型化 seam 不会为无类型调用方添加运行时校验或兼容回退。重复取消活动轮次时，首个信号生效；空闲取消是安全空操作，不发通知。ACP 映射到 `user`，进程内父传播映射到 `parent`。原因只存在于运行时；持久 `turn/end` 保持粗粒度的 `aborted`。

 A continuable background subagent is a durable child session with a series of Task-backed activations. `startContinuable()` allocates the stable child session id before Task creation, snapshots the descriptor inputs (a non-JSON input throws with no Task), and registers the initial activation's Task; the provider publishes exactly that child id and appends the versioned `subagent/descriptor` event inside the child's first turn. Every activation — initial or resumed — creates a fresh Task whose settlement awaits the provider's durability-confirmed child result, disposes the run, and only then records the `TaskOutcome`: a terminal Task leaves the durable child session but no live child Agent. A provider rejection with `DURABILITY_FAILED` settles the Task as `failed` and copies the error message into `detail`, so `task_output` reports the failed checkpoint and resumability risk without exposing unconfirmed output.
 
-`sendMessage(parent, childId, message, source)` owns steer-or-resume routing and requires the caller's `MessageSource`. A running activation preserves it through the run's strict `steer` capability and returns the existing Task id (`steered`); an absent activation starts a fresh Task that loads the persisted child, authorizes the recorded `parentSession` as the direct parent, folds the descriptor, and dispatches `SubagentService.resume()` with the same source (`started`). Either route projects the content to the model as a user-role message while retaining its source in the child log. Failure throws and means the message was not delivered: losing a strict-steering race with Task settlement never falls through to cold resume within the same call, and a live registry Agent outside the activation association is an ownership conflict rather than an adoption target.
+`sendMessage(parent, childId, message, source)` owns steer-or-resume routing and requires the caller's `MessageSource`. A running activation preserves it through the run's confirmed `steer` capability and returns the existing Task id (`steered`) only after a committed request snapshot admits the message; an absent activation starts a fresh Task that loads the persisted child, authorizes the recorded `parentSession` as the direct parent, folds the descriptor, and dispatches `SubagentService.resume()` with the same source (`started`). Either route projects the content to the model as a user-role message while retaining its source in the child log. Rejection means the message was not delivered: terminal policy or Task settlement winning the admission race never falls through to cold resume within the same call, and a live registry Agent outside the activation association is an ownership conflict rather than an adoption target.
 
 Cancellation targets the whole activation. `task_kill` or owner disposal aborts the Task-owned signal; before publication the provider rejects only after its creation transaction rolled back to quiescence, afterwards the signal cancels the published run, and settlement records `killed` only once the activation is quiescent. Human input shares this path: an adapter submits child input through `sendMessage()` under the loaded parent, so parent and human messages that joined one turn share its result and cancellation outcome, and `TaskService.start()`'s control-surface requirement applies (load `@deepseek-ai/dsh-tool-tasks` or attach a surface).

 After fulfillment, the caller owns the run. Provider-plugin unload does not revoke it. `dispose()` removes the live abort listener, records cancellation, and delegates to the returned `AgentHandle.dispose()`, whose memoized quiescence transaction stops the loop, removes the agent and session, and unwinds scoped registrations. Cancellation owns every non-completed in-flight outcome and reports `aborted`; an already-completed turn remains completed.
 
-Runs expose the strict `steer` capability: the synchronous checks and the `Agent.trySteer()` call share one frame, so delivery joins the observed step or throws. Delivery requires `AgentStatus.running`, an open turn and step in the child log, no committed structured capture, and acceptance before that step's final drain begins. Admission, between-step processing such as `agent/turn-stopping`, and a closed turn's durability flush all reject delivery. The Agent-level idle fallback (queue and start a new turn) is deliberately not reachable through the run — that would start an untracked turn after the run's result was read.
+Runs expose confirmed `steer`: a synchronous status check prevents the Agent-level idle fallback from starting an untracked turn, then the run submits through `Agent.steer()` and awaits that exact message's receipt. Fulfillment means a committed child request snapshot admitted the message; terminal turn policy, cancellation, disposal, or a settlement race rejects instead. A synchronously visible structured capture is rejected before submission because its terminal outcome is already authoritative. The run never falls through from rejected live delivery to a later queued turn or cold resume.

 该 seam 拥有实现和消费方共享的深度词汇：`AgentOptions.subagentDepth` 声明、`assertSubagentMaxDepth` 和 `delegationDepthOf(agent)`。持久化的 `SessionHeader.delegationDepth` 具有权威性且单调：运行时选项可以加深计数，但绝不能降低它，因此恢复后的子 agent 不会被重新计为顶层。
 
-运行时功能是 `SubagentRun` 上的可选方法：`sendMessage?` 可对正在运行的子 agent 进行 steering（中途引导），`resume?` 则异步创建延续运行。方法是否存在就是能力检查。

 `inheritsParentContext` 只用于描述，不能强制执行。它仅说明子 agent 是否能看到父级已完成的对话历史（`fork` 可以；`spawn` 和 ACP 不可以），不表示是否继承工具、服务或权限。

 `SubagentControlService`'s resume path loads the known child session, folds its descriptor, authorizes the persisted `parentSession`, and runs inside the Task it creates. It passes a fully resolved request, including the Task-owned cancellation signal, to the low-level `SubagentService.resume(provider, request)`, whose only responsibility is capability-checked provider dispatch and the ordinary run lifecycle observation used by `start`. The selected `SubagentProvider.resume?()` owns transport-specific reconstruction (in-process: `parent.ctx.agents.resume` under the currently loaded parent scope) and returns a fresh run. Presence of the provider method is the continuation capability, so no redundant capability flag exists. `SubagentControlService.sendMessage()` chooses between the associated run's `steer?()` operation and this cold-resume path. Neither the low-level service nor a provider enumerates durable children or associates Tasks.
 
-The background tool validates and snapshots descriptor inputs before calling `TaskService.start()`. A synchronous validation failure rejects the tool call and creates no Task. The tool otherwise returns the child and Task ids immediately, without waiting for child publication or descriptor durability. In-process continuable providers perform a final session flush after the child becomes idle and before reading the result; this retries a failed loop checkpoint while the child is still live. If the final confirmation fails, the provider rejects instead of returning unconfirmed output, the control service disposes the run, and the already-created Task settles as `failed` with the durability diagnosis in its detail. Foreground one-shot runs retain the loop's best-effort checkpoint behavior. In-process spawn and fork reconstruct composition under the currently loaded parent scope. A fork resume loads the child's own persisted transcript, which already contains the completed-turn prefix captured at initial creation; it never forks the parent's newer history again. Resuming a parent does not eagerly resume its children.

 TODO (ACP continuation): persist the remote ACP session id as provider-specific descriptor data and implement `AcpProvider.resume?()` as spawn, initialize, `loadSession`, then prompt. The initial ACP run must verify `initialize.agentCapabilities.loadSession`, and every resumed process must use the same durable backend; replayed history from `loadSession` must not be collected as the new activation's output. Because ACP load support is negotiated per child rather than established solely by the provider method's presence, this follow-up must also define how a start result advertises child-specific continuation before ACP children enter the durable catalog.

 Opening a child session in a human-facing adapter reads its persisted transcript and does not resume an Agent merely to display it. Human input starts or joins the same Task-backed activation used by parent input through the control service. A human-started Task retains the exact currently loaded parent Agent as its notification target, and `task_output` remains the single result path. The existing completion listener injects at most one unsolicited notice while the Task is unreported; `kill`, a terminal read, or a terminal wait may mark it reported and suppress that notice. Human interaction is therefore permitted only while that parent instance remains live. A user-owned conversation that may outlive the parent and explicitly merge a conclusion back belongs to [interactive side sessions](../../proposed/feature/2026-07-08-interactive-side-sessions.md), not this Task-owned lifecycle.

This dependency is the cost of using the same Task result, cancellation, and notification path for parent- and human-started activations.

A human-facing adapter that accepts child input must therefore attach a Task control surface, or run in a deployment that loads `@deepseek-ai/dsh-tool-tasks`; loading the Task service alone is insufficient. SDK-generated spawn and fork compositions mount `@deepseek-ai/dsh-tasks` and `@deepseek-ai/dsh-tool-tasks` with the subagent control pair. This dependency is the cost of using the same Task result, cancellation, and notification path for parent- and human-started activations.
 
 Cancellation always targets the whole current activation. If human and parent messages have joined one turn, either caller's cancellation aborts that turn, disposes its run, and settles its Task as `killed`; the messages do not have independent results or cancellation rights. Independent cancellation requires a later message to start a separate turn instead of steering the current one.

 ## Problem
 
 The subagent tool treats each delegation as one owned `SubagentRun`: foreground calls and background Tasks collect the result and then dispose the run. Disposal bounds the number of live child Agents and releases their scoped services, listeners, and provider resources. The persisted child session may survive, but the parent has no durable catalog or tool path for discovering that child and starting another turn on it.

 **Keep `resume?()` on the disposed run.** Retaining a disposed `SubagentRun` only to call `resume()` makes the old run double as a durable child handle and cannot reconstruct that object after restart. Service dispatch plus provider reconstruction makes the persistence boundary explicit.

+**Put control orchestration on `SubagentService`.** This service-placement alternative was later adopted by the [merged-service decision](../simplification/2026-07-26-merge-subagent-control-service.md), which keeps raw start/resume transport reusable while isolating optional Task and persistence work in an injected internal manager.
 
 **Add explicit activation phases.** Public `starting`/`running`/`settling` states could describe admission and cleanup precisely, but would add a lifecycle protocol the implementation does not otherwise need. The synchronous association install closes duplicate process-local cold resume without exposing those phases.

+# Agent Note: Merge subagent control into the subagent service
+
+Status: implemented

+
+## Problem
+
+Continuable-child orchestration originally lived in a separate `ctx.subagentControl` service above the raw `ctx.subagents` provider seam. That split kept provider dispatch independent of Tasks and persistence, and gave model and human adapters one orchestration contract. In practice the two services described one capability family, every continuable caller needed both, and the provider-bound delegation tool had to infer policy from `provider.resume` and inspect whether the control service and `send_message` tool happened to be loaded. This made sibling plugin presence decide execution semantics and coupled starting continuable work to an optional follow-up surface.
+
+## Decision
+
+`SubagentService` is the only public service. It retains raw `start(name, request)` and `resume(name, request)` for callers that own run collection, and exposes `startContinuable(spec)` and `sendMessage(...)` for durable Task-backed activations. The standalone `@deepseek-ai/dsh-subagent-control` package and `ctx.subagentControl` key are deleted; the optional `@deepseek-ai/dsh-tool-subagent-control` package injects `ctx.subagents` directly.
+
+The continuation implementation remains an internal manager rather than expanding the provider registry's core state. `SubagentService` creates it through `ctx.inject(['tasks', 'agents'], ...)`, so the injected Cordis child fiber owns its Task completion listener and teardown effects. Loading the provider registry does not require Tasks or persistence. The manager exists only while Tasks and Agents are available, and each continuation operation resolves session persistence at the point it needs durability. Disposing that fiber cancels and settles active continuations before releasing their associations.
+
+`startContinuable` remains distinct from raw `start` because it has a different ownership and timing contract: it allocates the durable child id, creates the Task, and returns both ids synchronously while startup continues inside the Task. Raw `start` instead awaits provider publication and transfers a holder-owned run. Folding the method onto `start` through flags or return unions would broaden the low-level contract and create more change than keeping the existing explicit entry.
+
+Each `@deepseek-ai/dsh-tool-subagent` instance selects `backgroundMode: 'one-shot' | 'continuable'`, defaulting to `one-shot`. This configuration is policy; `provider.resume` is only the capability check for configured continuable mode. A resumable provider can therefore still run one-shot background work. The `send_message` tool is an independent adapter: loading or omitting it neither enables nor disables `startContinuable`.
+
+## Alternatives considered
+
+**Keep the separate service.** This preserves the strongest dependency separation, but every production continuable path composes both services and the extra public key exposes an architectural distinction callers do not need. The internal manager preserves optional Task and persistence dependencies without a second service.
+
+**Infer continuable mode from `provider.resume`.** Method presence correctly states cold-resume capability but not deployment policy. It forced every resumable provider into continuable background semantics and made missing sibling plugins a runtime error. Explicit tool configuration separates choice from capability.
+
+**Register continuation access or inspect the follow-up tool.** A registry could tell the delegation tool whether a continuation surface exists, but starting durable work does not require any follow-up adapter. Such a registry would encode UI composition into execution policy and recreate the sibling dependency under another name.
+
+**Merge raw and continuable starts into one method.** A flag on `start` would return either a ready run or immediate Task and child identities, weakening a simple ownership boundary. Keeping `startContinuable` is the smaller change and preserves both contracts explicitly.
+
+## Consequences
+
+- The service topology has one public key and one package fewer while raw provider dispatch remains usable without Tasks or persistence.
+- Continuable mode fails at provider mount when the configured provider lacks `resume`; missing Tasks, Agents, or persistence still fail at the earliest operation that requires them.
+- Follow-up delivery remains optional. Deployments may start and collect continuable work through Task tools without exposing `send_message`.
+- The continuation manager is still Task- and persistence-aware inside the `dsh-subagent` package, so the package declares optional peer dependencies on those services even though ordinary `start` and `resume` callers do not need them.
+- Existing continuation races, authorization, durability, cancellation, and settle-then-dispose semantics are unchanged and remain pinned by the migrated `subagent` tests.

+# Agent Note: 将 subagent 控制合并到 subagent 服务
+
+Status: implemented
+
+[English](2026-07-26-merge-subagent-control-service.md) | 中文
+
+## 问题
+
+可继续 child 的编排最初位于原始 `ctx.subagents` 提供方 seam 之上的独立 `ctx.subagentControl` 服务中。该拆分使提供方分发与 Task 和持久化无关，并为模型与人工适配器提供统一的编排契约。实践中，两个服务属于同一组功能，每个可继续调用方都需要二者，而绑定提供方的委派工具必须根据 `provider.resume` 推断策略，并检查控制服务与 `send_message` 工具是否碰巧已加载。如此一来，配套插件是否存在会决定执行语义，并将可继续工作的启动耦合到可选的后续操作接口。
+
+## 决策
+
+`SubagentService` 是唯一的公开服务。它为自行收集 run 的调用方保留底层 `start(name, request)` 和 `resume(name, request)`，并公开 `startContinuable(spec)` 与 `sendMessage(...)`，用于具备持久性、由 Task 支撑的激活。系统删除独立的 `@deepseek-ai/dsh-subagent-control` 包（package）和 `ctx.subagentControl` 键；可选的 `@deepseek-ai/dsh-tool-subagent-control` 包则直接注入 `ctx.subagents`。
+
+继续执行的实现仍是内部管理器，不会扩展提供方注册表的核心状态。`SubagentService` 通过 `ctx.inject(['tasks', 'agents'], ...)` 创建该管理器，因此注入的 Cordis child fiber 拥有自身的 Task 完成监听器和拆卸 effect。加载提供方注册表不要求 Task 或持久化。只有 Task 和 Agent 可用时，该管理器才会存在；每项继续执行操作都在需要持久性时解析会话持久化服务。dispose（资源释放）该 fiber 会先取消并结算活跃的继续执行，再释放其关联。
+
+`startContinuable` 与底层 `start` 保持分离，因为二者的所有权与时序契约不同：前者分配持久化 child id、创建 Task，并同步返回两个 id，而启动过程继续在 Task 内运行；底层 `start` 则等待提供方发布，并移交一个由持有方负责的 run。若通过标志或返回值联合类型将该方法并入 `start`，会扩大底层契约，改动反而多于保留现有的显式入口。
+
+每个 `@deepseek-ai/dsh-tool-subagent` 实例都会选择 `backgroundMode: 'one-shot' | 'continuable'`，默认值为 `one-shot`。这项配置表示策略；`provider.resume` 只用于检查所配置的可继续模式是否受提供方支持。因此，可恢复的提供方仍可执行一次性后台工作。`send_message` 工具是独立适配器：加载或省略该工具既不会启用也不会禁用 `startContinuable`。
+
+## 已考虑的替代方案
+
+**保留独立服务。** 这样能保持最严格的依赖分离，但每条生产环境中的可继续路径都要组合两个服务，而额外的公开键会暴露调用方并不需要的架构差异。内部管理器无需第二个服务，也能保留可选的 Task 和持久化依赖。
+
+**根据 `provider.resume` 推断可继续模式。** 方法是否存在可以准确表示从持久化存储恢复的功能，却不能表示部署策略。这会迫使每个可恢复的提供方都采用可继续后台语义，并使配套插件缺失成为运行时错误。显式的工具配置将选择与功能分离。
+
+**注册继续执行访问入口，或检查后续操作工具。** 注册表可以告诉委派工具继续执行接口是否存在，但启动具备持久性的工作不需要任何后续操作适配器。这样的注册表会把 UI 组合编码进执行策略，并以另一个名称重新建立插件间依赖关系。
+
+**将底层启动与可继续启动合并为一个方法。** `start` 上的标志会使该方法返回就绪的 run，或立即返回 Task 和 child 标识，从而削弱简单的所有权边界。保留 `startContinuable` 改动更小，也能明确保留两项契约。
+
+## 影响
+
+- 服务拓扑少了一个公开键和一个包，同时底层提供方分发仍可在没有 Task 或持久化时使用。
+- 配置的提供方缺少 `resume` 时，可继续模式会在提供方挂载阶段失败；缺少 Task、Agent 或持久化时，仍会在需要它们的最早操作处失败。
+- 后续消息投递仍为可选功能。部署可以通过 Task 工具启动并收集可继续工作，而不公开 `send_message`。
+- `dsh-subagent` 包内的继续执行管理器仍然感知 Task 和持久化，因此该包会将这些服务声明为可选的对等依赖（peer dependency），即使普通的 `start` 和 `resume` 调用方并不需要它们。
+- 现有的继续执行竞态、授权、持久性、取消及先结算再 dispose 的语义均保持不变，并继续由迁移后的 `subagent` 测试固定。

 The subagent seam — an agent delegating work to a child agent.

 ## Continuable children: `SubagentContinuation` and `SubagentResumeRequest`
 
-A **continuable background subagent** is a durable child session with a series of Task-backed activations. `ctx.subagentControl` (`SubagentControlService` in [dsh-subagent-control](../../packages/subagent/subagent-control)) allocates the stable child id, snapshots the versioned `subagent/descriptor` payload, and passes both through the resolved start request; the provider publishes exactly that id and appends the descriptor inside the child's first turn. On follow-up, the control service loads the persisted child, authorizes the recorded `parentSession` as the direct parent, folds the descriptor, and dispatches a fully resolved resume request through `SubagentService.resume()` to `SubagentProvider.resume()`. The seam stays Task- and persistence-agnostic — descriptor lookup and Task association live only in the control service. `startContinuable()` returns a `ContinuableStart` (both identities), and `sendMessage()` returns a `SendMessageResult` reporting whether the message `steered` the running activation's existing Task or `started` a fresh one. Every sender supplies a `MessageSource`; the model-facing tool uses `CoordinatorMessageSource`, while a human adapter uses `{ kind: 'user' }`. Both project to a user-role model message, but the durable source remains distinct for policy and title consumers.

An internal manager owns descriptor lookup and Task association only while `ctx.tasks` and `ctx.agents` exist; persistence is required per continuation operation, not to load the provider registry. `startContinuable()` returns both identities, while `sendMessage()` reports whether the message `steered` the existing Task or `started` a fresh one. Every sender supplies a `MessageSource`; the optional model-facing tool uses `CoordinatorMessageSource`, while a human adapter uses `{ kind: 'user' }`.

-# @deepseek-ai/dsh-subagent-control
-
-The continuable-subagent control service (`ctx.subagentControl`): the one orchestration path that binds a durable child session to a series of disposable Task-backed activations. Model tools and human-facing adapters call the same contract; the low-level `ctx.subagents` seam stays collection-, Task-, and persistence-agnostic.
-
-## Activation lifecycle
-
-A continuable background subagent is a durable child session with a series of Task-backed activations. `startContinuable()` allocates the stable child session id before Task creation, snapshots the descriptor inputs (a non-JSON input throws with no Task), and registers the initial activation's Task; the provider publishes exactly that child id and appends the versioned `subagent/descriptor` event inside the child's first turn. Every activation — initial or resumed — creates a fresh Task whose settlement awaits the provider's durability-confirmed child result, disposes the run, and only then records the `TaskOutcome`: a terminal Task leaves the durable child session but no live child Agent. A provider rejection with `DURABILITY_FAILED` settles the Task as `failed` and copies the error message into `detail`, so `task_output` reports the failed checkpoint and resumability risk without exposing unconfirmed output.
-
-`sendMessage(parent, childId, message, source)` owns steer-or-resume routing and requires the caller's `MessageSource`. A running activation preserves it through the run's confirmed `steer` capability and returns the existing Task id (`steered`) only after a committed request snapshot admits the message; an absent activation starts a fresh Task that loads the persisted child, authorizes the recorded `parentSession` as the direct parent, folds the descriptor, and dispatches `SubagentService.resume()` with the same source (`started`). Either route projects the content to the model as a user-role message while retaining its source in the child log. Rejection means the message was not delivered: terminal policy or Task settlement winning the admission race never falls through to cold resume within the same call, and a live registry Agent outside the activation association is an ownership conflict rather than an adoption target.
-
-Cancellation targets the whole activation. `task_kill` or owner disposal aborts the Task-owned signal; before publication the provider rejects only after its creation transaction rolled back to quiescence, afterwards the signal cancels the published run, and settlement records `killed` only once the activation is quiescent. Human input shares this path: an adapter submits child input through `sendMessage()` under the loaded parent, so parent and human messages that joined one turn share its result and cancellation outcome, and `TaskService.start()`'s control-surface requirement applies (load `@deepseek-ai/dsh-tool-tasks` or attach a surface).
-
-The activation association is process-local routing state, installed before any persistence or provider await and removed after run disposal and Task terminal publication. It is not a durable catalog: restart recovers the child session, not in-flight Tasks or their notifications.
-
-## Model Experience
-
-### Task completion and output
-
-#### What the model sees
-
-None directly, as this package registers no tool and no prompt text; the model observes continuable children through `@deepseek-ai/dsh-tool-subagent`'s background acknowledgement, `@deepseek-ai/dsh-tool-subagent-control`'s `send_message` results, and the generic task surface, whose outputs this service produces.
-
-#### Token effect
-
-None beyond the consuming tools' own results.
-
-#### KV Cache effect
-
-None; this service appends nothing to any model-visible sequence.
-
-## Known Limitations and Deferred Work
-
-- **Concurrent stopped-child admission is not atomic across awaits** — the synchronous association install admits one activation per child in this process, but a caller bypassing the control service can still race it; the Agent registry's same-id collision is the final backstop, and the losing Task fails with its message not delivered.
-- **The association coordinates only one runtime** — concurrent resume from multiple processes needs a persistence-level lease or compare-and-set, which no backend offers yet.
-- **Task records are process-local** — restart recovers the durable child session, not an interrupted Task, its result, or its completion notice; durable Task recovery is a separate concern.
-- **Human interaction requires the exact live parent Agent** — Task access is fenced by the owner session and owner disposal cancels its Tasks; standalone child conversations belong to the interactive-side-sessions proposal, not this Task-owned lifecycle.
-- **ACP children remain one-shot** — `AcpProvider.resume` and per-child continuation advertisement are deferred until the remote-session descriptor contract is resolved.

Continuable background delegation calls `ctx.subagents.startContinuable()`, whose internal manager exists only while `ctx.tasks` and `ctx.agents` are available; session persistence is resolved per continuation operation. Collection and cancellation use the shared task tools. See the [background subagent tasks Agent Note](../../../.agents/notes/implemented/feature/2026-07-08-background-subagent-tasks.md), the [continuable background subagents Agent Note](../../../.agents/notes/implemented/feature/2026-07-21-continuable-background-subagents.md), the [merged-service Agent Note](../../../.agents/notes/implemented/simplification/2026-07-26-merge-subagent-control-service.md), the [capability-seam Agent Note](../../../.agents/notes/implemented/feature/2026-06-21-subagent-capability-seam.md), and `src/types.ts` for the complete contracts.

+The optional, globally named `send_message` tool: a thin adapter over `ctx.subagents.sendMessage()`. Provider-bound `@deepseek-ai/dsh-tool-subagent` instances register distinct delegation tools per transport; this separately loaded package registers one shared follow-up tool, so multiple delegation tools never register duplicate global controls. Its presence does not determine whether a delegation tool starts continuable work.
 
-The tool performs no lifecycle routing. It attributes every follow-up as `{ kind: 'coordinator', senderSessionId: parent.id }`; the control service preserves that source while deciding between live delivery to the running activation's existing Task and a fresh Task that cold-resumes the durable child. The tool renders which route was taken and the relevant Task id. A control-service throw becomes an errored tool result stating the message was not delivered.

 ### Task and cancellation ownership
 
-The initial background delegation asks the control service to start the child and register its Task. A continuable provider confirms the activation's final session state durable before fulfilling a successful run result. Task settlement awaits that result, calls `run.dispose()` (through the control service's `settleRun`), and only then records the `TaskOutcome`; `task_kill` aborts the active run, whose settlement path still disposes it. A terminal Task therefore leaves the durable child session but no live child Agent. A failed required durability checkpoint rejects the run with stable code `DURABILITY_FAILED` and the backend failure as its cause; the control service records a failed Task whose detail explains that the latest state was not confirmed persisted and may be unavailable or stale on resume.

 Every later turn creates another Task. Its producer resources cover only that activation, never the child session. It reaches one terminal status, has one result, and is never reopened. The exact live parent Agent remains the Task registry owner: disposing that instance cancels, awaits, and removes its Tasks. Task APIs authorize a caller whose session id matches that owner, but a same-id replacement does not become the notification or teardown target. This preserves the `settleRun()` contract and bounds Task-owned live children by concurrent work rather than historical session count.

Activation cancellation during this await owns the unpublished result even when the completed turn was already recorded or the checkpoint subsequently fails. Foreground runs keep the loop's best-effort checkpoint behavior.
 6. Read the child's own last assistant message and latest message-triggered turn reason, excluding any fork seed and later plugin-owned between-turn records.
 
 The child gets the parent's working-directory/session lineage and inherits the parent provider, model, and output-token cap unless `request.agentOptions` overrides them. It gets a fresh flat registration scope: parent ownership does not import parent tool restrictions or establish an authority subset.

 `SubagentService` is the only public service. It retains raw `start(name, request)` and `resume(name, request)` for callers that own run collection, and exposes `startContinuable(spec)` and `sendMessage(...)` for durable Task-backed activations. The standalone `@deepseek-ai/dsh-subagent-control` package and `ctx.subagentControl` key are deleted; the optional `@deepseek-ai/dsh-tool-subagent-control` package injects `ctx.subagents` directly.
 
+The merged service and its providers expose one `SubagentError` taxonomy. Stable codes distinguish provider lookup and capability failures from continuation routing, authorization, cancellation, persistence, and delivery failures; the removed service does not retain a separate error class.
+
 The continuation implementation remains an internal manager rather than expanding the provider registry's core state. `SubagentService` creates it through `ctx.inject(['tasks', 'agents'], ...)`, so the injected Cordis child fiber owns its Task completion listener and teardown effects. Loading the provider registry does not require Tasks or persistence. The manager exists only while Tasks and Agents are available, and each continuation operation resolves session persistence at the point it needs durability. Disposing that fiber cancels and settles active continuations before releasing their associations.
 
 `startContinuable` remains distinct from raw `start` because it has a different ownership and timing contract: it allocates the durable child id, creates the Task, and returns both ids synchronously while startup continues inside the Task. Raw `start` instead awaits provider publication and transfers a holder-owned run. Folding the method onto `start` through flags or return unions would broaden the low-level contract and create more change than keeping the existing explicit entry.

 `SubagentService` 是唯一的公开服务。它为自行收集 run 的调用方保留底层 `start(name, request)` 和 `resume(name, request)`，并公开 `startContinuable(spec)` 与 `sendMessage(...)`，用于具备持久性、由 Task 支撑的激活。系统删除独立的 `@deepseek-ai/dsh-subagent-control` 包（package）和 `ctx.subagentControl` 键；可选的 `@deepseek-ai/dsh-tool-subagent-control` 包则直接注入 `ctx.subagents`。
 
+合并后的服务及其提供方公开一套 `SubagentError` 分类体系。稳定错误码把提供方查找失败和功能检查失败，与继续执行路由、鉴权、取消、持久化和送达失败区分开来；已移除的服务不保留单独的错误类。
+
 继续执行的实现仍是内部管理器，不会扩展提供方注册表的核心状态。`SubagentService` 通过 `ctx.inject(['tasks', 'agents'], ...)` 创建该管理器，因此注入的 Cordis child fiber 拥有自身的 Task 完成监听器和拆卸 effect。加载提供方注册表不要求 Task 或持久化。只有 Task 和 Agent 可用时，该管理器才会存在；每项继续执行操作都在需要持久性时解析会话持久化服务。dispose（资源释放）该 fiber 会先取消并结算活跃的继续执行，再释放其关联。
 
 `startContinuable` 与底层 `start` 保持分离，因为二者的所有权与时序契约不同：前者分配持久化 child id、创建 Task，并同步返回两个 id，而启动过程继续在 Task 内运行；底层 `start` 则等待提供方发布，并移交一个由持有方负责的 run。若通过标志或返回值联合类型将该方法并入 `start`，会扩大底层契约，改动反而多于保留现有的显式入口。

 ### Durable child handle and cold resume
 
-The control service snapshots every descriptor input with the seam's `snapshotSubagentDescriptor()` (built on [`snapshotJsonValue`](../../../../packages/core/session/src/json.ts)) before Task creation, matching the detached lossless-JSON boundary already used by Agent messages. A child-scoped setup contribution — a one-shot `agent/pre-step` listener installed by the in-process driver — appends one model-hidden `subagent/descriptor` event after the initial child `turn/start` and before its first request; it carries no `surfaceOp`, remains outside model history, and reaches persistence with that turn's flush. The append-only log retains this non-surface event when compaction replaces surface history. A known child id is resumable only when loading that child session yields a supported descriptor in the child's own suffix (after `seedLength`, so a fork seed cannot leak an ancestor's descriptor) and its header identifies the caller as the direct parent.

Allowed admission opens the initial child turn afterward; rejected admission leaves the descriptor as a pre-turn log-only fact, and the activation's final required checkpoint persists it. The event carries no `surfaceOp`, remains outside model history, and survives when compaction replaces surface history. A known child id is resumable only when loading that child session yields a supported descriptor in the child's own suffix (after `seedLength`, so a fork seed cannot leak an ancestor's descriptor) and its header identifies the caller as the direct parent.
 
 The versioned descriptor (`SUBAGENT_DESCRIPTOR_VERSION` in [descriptor.ts](../../../../packages/subagent/subagent/src/descriptor.ts)) contains the subagent provider name, resolved child `agentOptions.provider` and `agentOptions.model`, and optional `persona` and `toolFilter`. It does not snapshot the merge-extensible `AgentOptions` object: unrelated extension values cannot make continuation fail merely because they are not JSON. It deliberately omits `subagentDepth`; cold resume relies on the persisted header's `delegationDepth` rather than reconstructing depth from the descriptor. `outputSchema` belongs to one activation's result contract rather than durable child composition. The child header remains authoritative for the child id, `cwd`, `parentSession`, `seedLength`, and `delegationDepth`, while the persisted child transcript owns the fork seed and subsequent history. [`delegationDepthOf()`](../../../../packages/subagent/subagent/src/index.ts) takes the maximum of header and runtime values, so reconstructed runtime options may deepen the persisted value but never lower it and a resumed child cannot regain a top-level delegation budget.

 `TaskService.start()` rejects producers when no Task control surface is attached. A human-facing adapter that accepts child input must therefore attach a Task control surface, or run in a deployment that loads `@deepseek-ai/dsh-tool-tasks`; loading the Task service alone is insufficient. SDK-generated spawn and fork compositions mount `@deepseek-ai/dsh-tasks` and `@deepseek-ai/dsh-tool-tasks` with the subagent control pair. This dependency is the cost of using the same Task result, cancellation, and notification path for parent- and human-started activations.
 
-Cancellation always targets the whole current activation. If human and parent messages have joined one turn, either caller's cancellation aborts that turn, disposes its run, and settles its Task as `killed`; the messages do not have independent results or cancellation rights. Independent cancellation requires a later message to start a separate turn instead of steering the current one.
+Cancellation always targets the whole current activation. If human and parent messages have joined one turn, either caller's cancellation aborts that turn, disposes its run, and settles its Task as `killed`; the messages do not have independent results or cancellation rights. `sendMessage()` requires the caller's signal, and abort while live steering awaits request admission aborts the activation-owned controller so the provider discards the pending message and the call settles only after the child reaches quiescence. Independent cancellation requires a later message to start a separate turn instead of steering the current one.
 
 A cold-resume Task creates its activation-owned `AbortController` before descriptor lookup or any provider await; the lookup, direct-parent authorization, and descriptor fold run inside the Task producer, so the same signal covers them and their failures settle that Task as `failed`. A persistence call that has no signal need not stop its underlying I/O, but the control service rechecks cancellation after every such await and cannot begin or publish child work afterward. Before Agent publication, abort makes the provider reject only after its creation transaction has rolled back and reached quiescence. After publication, the provider closes the creation-signal handoff race, attaches the same signal to the live run before returning it, and cancellation stops the child turn. `task_kill` and exact-owner disposal use this path even when provider resume has not returned a `SubagentRun`; Task settlement waits for rollback or run disposal and records `killed` only after the activation is quiescent.

An internal manager owns descriptor lookup and Task association only while `ctx.tasks` and `ctx.agents` exist; persistence is required per continuation operation, not to load the provider registry. `startContinuable()` returns both identities, while `sendMessage()` reports whether the message `steered` the existing Task or `started` a fresh one.

+**可继续后台 subagent** 是一份持久化子 agent 会话，由一系列由 Task 支撑的激活组成。`SubagentService.startContinuable()` 会分配稳定的子 agent id、对版本化的 `subagent/descriptor` payload 建立快照，并通过已解析的启动请求传入二者；提供方会准确发布该 id，并在初始 prompt 获准前追加描述符。`SubagentService.sendMessage()` 会先加载并授权已停止的子 agent，再通过底层 `resume()` 操作分发完全解析的恢复请求，或引导其实时激活。只有 `ctx.tasks` 和 `ctx.agents` 存在时，内部管理器才会负责描述符查找与 Task 关联；每项继续执行操作都要求持久化，而加载提供方注册表不要求持久化。`startContinuable()` 返回两个标识，`sendMessage()` 则报告消息是对现有 Task 执行了 `steered`，还是 `started` 一个新 Task。每个发送方都会提供 `MessageSource` 和取消信号；若在在线投递等待准入期间中止该信号，则会取消共享激活，并在其完全停稳后拒绝调用。可选的面向模型工具使用 `CoordinatorMessageSource` 及其工具执行信号，人工适配器则使用 `{ kind: 'user' }` 及其交互信号。

 # @deepseek-ai/dsh-tool-subagent-control
 
+English | [中文](README.zh.md)
+
 The optional, globally named `send_message` tool: a thin adapter over `ctx.subagents.sendMessage()`. Provider-bound `@deepseek-ai/dsh-tool-subagent` instances register distinct delegation tools per transport; this separately loaded package registers one shared follow-up tool, so multiple delegation tools never register duplicate global controls. Its presence does not determine whether a delegation tool starts continuable work.
 
-The tool performs no lifecycle routing. It attributes every follow-up as `{ kind: 'coordinator', senderSessionId: parent.id }`; the subagent service preserves that source while deciding between live delivery to the running activation's existing Task and a fresh Task that cold-resumes the durable child. The tool renders which route was taken and the relevant Task id. A delivery failure becomes an errored tool result stating the message was not delivered.
+The tool performs no lifecycle routing. It attributes every follow-up as `{ kind: 'coordinator', senderSessionId: parent.id }`; the subagent service preserves that source while deciding between live delivery to the running activation's existing Task and a fresh Task that cold-resumes the durable child. The tool forwards its execution signal, so cancellation while live delivery awaits admission cancels the shared activation and settles only after the child reaches quiescence. The tool renders which route was taken and the relevant Task id. A delivery failure becomes an errored tool result stating the message was not delivered.

+
+[English](README.md) | 中文
+
+可选的全局具名 `send_message` 工具：`ctx.subagents.sendMessage()` 之上的轻量适配器。绑定提供方的 `@deepseek-ai/dsh-tool-subagent` 实例会为每种传输注册不同的委派工具；这个单独加载的包（package）只注册一个共享后续操作工具，因此多个委派工具绝不会重复注册全局控制工具。是否加载本工具不会决定委派工具是否启动可继续工作。
+
+本工具不执行生命周期路由。它将每条后续消息的来源标记为 `{ kind: 'coordinator', senderSessionId: parent.id }`；subagent 服务会保留该来源，并在向运行中激活的现有 Task 在线投递消息与创建新 Task、从持久化存储恢复子 agent 之间做出选择。本工具会转发其执行信号，因此，若在在线投递等待准入期间取消，则会取消共享激活，并仅在子 agent 完全停稳后结算。本工具会渲染实际采用的路由及相关 Task id。投递失败会变为出错的工具结果，并明确说明消息未送达。
+
+## 模型体验
+
+### 工具 schema
+
+#### 模型看到的内容
+
+已生成的 [`send_message` schema](../../../docs/tool-catalog.md#deepseek-aidsh-tool-subagent-control)：包含 `subagent_id` 和 `message`，说明投递或继续执行的语义，以及通过 `task_output` 收集结果的路径。
+
+#### Token 影响
+
+每个父级请求支付固定的 schema 成本。
+
+#### KV Cache 影响
+
+前缀保持稳定；schema 不会在运行时改变。
+
+### 投递结果
+
+#### 模型看到的内容
+
+消息加入运行中的激活时返回 `message delivered to running task `；消息启动一次从持久化存储恢复的激活时返回 `message started task  continuing subagent `。同步路由失败，包括所有权冲突、steering（中途引导）竞态失败和缺少在线投递功能，都会成为出错的结果，其消息说明该消息未送达。不存在激活时始终报告 `started`：查找在该 Task 内运行，因此未知、属于其他 parent 或缺少描述符的子 agent 会表现为已启动的 Task 结算为 `failed`（通过 `task_output` 读取），而不是出错的 `send_message` 结果。
+
+#### Token 影响
+
+每次调用产生一条简短确认消息；子 agent 的响应只会在通过 `task_output` 收集时进入父级历史（完成通知是状态行，绝不是响应）。
+
+#### KV Cache 影响
+
+仅追加；新增可见内容位于可复用请求前缀之后，不会使现有 KV-cache 条目失效。
+
+## 已知限制与延期工作
+
+- **已投递的消息没有独立结果**：其效果体现在当前 Task 的最终结果中；只有已启动的后续操作才拥有新的 Task 结果。
+- **投递可能在时序竞态中失败**：消息与 Task 结算、取消或清理发生竞态时会明确失败，不会改用从持久化存储恢复；模型会在 Task 结算后重试。

 The service validates provider capabilities and request semantics before calling the provider. A provider rejection cleans any partial resources before the rejection escapes and emits no `subagent/start`/`subagent/end` pair. After fulfillment, the service attaches result observation, emits scoped start, and returns the run. Provider removal prevents later starts but does not revoke a run already accepted by the provider.

Parent-to-child enumeration and `list_agents` belong to a separate durable-catalog proposal.
 
 ### Task and cancellation ownership
 
-The initial background delegation asks the control service to start the child and register its Task. A continuable provider confirms the activation's final session state durable before fulfilling a successful run result. Task settlement awaits that result, calls `run.dispose()` (through the control service's `settleRun`), and only then records the `TaskOutcome`; `task_kill` aborts the active run, whose settlement path still disposes it. A terminal Task therefore leaves the durable child session but no live child Agent. A required durability checkpoint with no installed listener or a failing listener rejects the run with stable code `DURABILITY_FAILED` and the checkpoint failure as its cause; the control service records a failed Task whose detail explains that the latest state was not confirmed persisted and may be unavailable or stale on resume.

A required durability checkpoint with no installed listener or a failing listener rejects the run with stable code `DURABILITY_FAILED` and the checkpoint failure as its cause; the manager records a failed Task whose detail explains that the latest state was not confirmed persisted and may be unavailable or stale on resume.
 
 Every later turn creates another Task. Its producer resources cover only that activation, never the child session. It reaches one terminal status, has one result, and is never reopened. The exact live parent Agent remains the Task registry owner: disposing that instance cancels, awaits, and removes its Tasks. Task APIs authorize a caller whose session id matches that owner, but a same-id replacement does not become the notification or teardown target. This preserves the `settleRun()` contract and bounds Task-owned live children by concurrent work rather than historical session count.
 
-Opening a child session in a human-facing adapter reads its persisted transcript and does not resume an Agent merely to display it. Human input starts or joins the same Task-backed activation used by parent input through the control service. A human-started Task retains the exact currently loaded parent Agent as its notification target, and `task_output` remains the single result path. The existing completion listener injects at most one unsolicited notice while the Task is unreported; `kill`, a terminal read, or a terminal wait may mark it reported and suppress that notice. Human interaction is therefore permitted only while that parent instance remains live. A user-owned conversation that may outlive the parent and explicitly merge a conclusion back belongs to [interactive side sessions](../../proposed/feature/2026-07-08-interactive-side-sessions.md), not this Task-owned lifecycle.

A human-facing adapter that accepts child input must therefore attach a Task control surface, or run in a deployment that loads `@deepseek-ai/dsh-tool-tasks`; loading the Task service alone is insufficient. SDK-generated spawn and fork compositions mount `@deepseek-ai/dsh-tasks` and `@deepseek-ai/dsh-tool-tasks` with the subagent control pair. This dependency is the cost of using the same Task result, cancellation, and notification path for parent- and human-started activations.

-Cancellation always targets the whole current activation. If human and parent messages have joined one turn, either caller's cancellation aborts that turn, disposes its run, and settles its Task as `killed`; the messages do not have independent results or cancellation rights. `sendMessage()` requires the caller's signal, and abort while live steering awaits request admission aborts the activation-owned controller so the provider discards the pending message and the call settles only after the child reaches quiescence. Independent cancellation requires a later message to start a separate turn instead of steering the current one.

-A cold-resume Task creates its activation-owned `AbortController` before descriptor lookup or any provider await; the lookup, direct-parent authorization, and descriptor fold run inside the Task producer, so the same signal covers them and their failures settle that Task as `failed`. A persistence call that has no signal need not stop its underlying I/O, but the control service rechecks cancellation after every such await and cannot begin or publish child work afterward. Before Agent publication, abort makes the provider reject only after its creation transaction has rolled back and reached quiescence. After publication, the provider closes the creation-signal handoff race, attaches the same signal to the live run before returning it, and cancellation stops the child turn. `task_kill` and exact-owner disposal use this path even when provider resume has not returned a `SubagentRun`; Task settlement waits for rollback or run disposal and records `killed` only after the activation is quiescent.

 ### Active run association
 
-The control service keeps a process-local association from child session id to its current Task and, after provider publication, its run. It installs the Task association before awaiting provider start or resume, fills in the returned run, and removes the association only after run disposal and Task terminal publication. This association exists only so parent and human senders can find the same activation; it is not a durable catalog, public `ManagedSubagent`, admission reservation, or run-state machine.

This association exists only so parent and human senders can find the same activation; it is not a durable catalog, public `ManagedSubagent`, admission reservation, or run-state machine.
 
-For a continuable initial activation, the control service allocates the stable child session id before Task creation and passes it in the resolved provider start request (`SubagentStartRequest.continuation`); in-process spawn and fork publish that exact id instead of allocating one internally. The background tool acknowledgement exposes both identities as `started subagent  as task `. The child id names the durable conversation across activations, while the Task id names only the current activation. A failed initial Task or a process exit before the first child flush can leave an **unmaterialized child**: the caller holds a child id without a durable header and descriptor. Later by-id control operations report that id as unavailable (the started Task fails with that detail), and durable enumeration omits it.

-Every continuable child turn is admitted through this Task-backed path. A non-terminal Task is the only supported live activation; when no activation exists, its run has already been disposed and the durable child is resumable. Before routing any by-id operation, the control service synchronously compares its association with `ctx.agents.get(childId)`. A registry Agent with no association, or a registry Agent different from the associated `run.localAgent`, is an ownership conflict: the control service fails rather than adopting an idle Agent or attaching an untracked turn. When neither exists, cold resume may proceed; a competing publication after that check still loses at the Agent registry collision boundary.

When neither exists, cold resume may proceed; a competing publication after that check still loses at the Agent registry collision boundary.
 
-Routing follows the Task association. A running Task accepts live delivery through the run's optional confirmed `SubagentRun.steer` capability. An absent Task starts a fresh Task and cold-resumes the child. In-process spawn and fork first synchronously require the child to be `running` and reject an already committed structured capture, then call `Agent.steer()` and await that exact message's admission receipt. The default loop gives every steering item a message-owned receipt and resolves it `admitted` only after a successful pre-step has appended the message, captured the immutable request history, and committed `step/start`; terminal turn policy, cancellation, and disposal resolve pending receipts `rejected`. A non-terminal turn close may carry pending steering into a later queued turn without acknowledging it. Providers must check the live status before `Agent.steer()` so its idle path cannot start a turn outside the observed run. If Task settlement or terminal policy wins after association lookup but before request admission, `steer()` rejects, `send_message` reports the message as not delivered, and that call does not fall through to cold resume; a later retry after Task terminal may start the next activation.

-The control service does not serialize two callers that race a stopped child through paths outside it, nor does it model a separate settling phase between result production and disposal. The synchronous association install before the producer's first await admits one activation per child in this process — a competing `sendMessage` during resume load observes the pending activation and fails explicitly — while a bypassing publication still loses at the Agent registry's same-session collision boundary. Delivery racing startup, cancellation, completion, or cleanup may also fail. These limitations are explicit rather than hidden behind a larger lifecycle abstraction.

 ### Model-facing `send_message`
 
-The model receives one `send_message(subagent_id, message)` tool backed by `SubagentControlService.sendMessage()`. The control operation owns steer-or-resume orchestration and is distinct from the run's `SubagentRun.steer?()`, which only delivers to an already active run. The tool performs no lifecycle routing of its own. It attributes the follow-up as `{ kind: 'coordinator', senderSessionId: parent.id }` and forwards its execution signal; the control service requires both the caller-supplied `MessageSource` and cancellation signal. The source crosses both live steering and cold resume, while cancellation owns only a pending live-delivery wait because a cold-resume Task returns immediately and owns its later cancellation. The child model still receives ordinary user-role content, while the durable source prevents model-generated follow-ups from being classified as direct human input. A human adapter instead supplies `{ kind: 'user' }` and its interaction signal. The tool lives in the separately loaded `@deepseek-ai/dsh-tool-subagent-control` package so provider-bound `@deepseek-ai/dsh-tool-subagent` instances can continue registering distinct delegation tools for spawn, fork, or ACP without registering duplicate global control tools.

 ### Durable child handle and cold resume
 
-The control service snapshots every descriptor input with the seam's `snapshotSubagentDescriptor()` (built on [`snapshotJsonValue`](../../../../packages/core/session/src/json.ts)) before Task creation, matching the detached lossless-JSON boundary already used by Agent messages. A child-scoped setup contribution — a prepended one-shot `agent/prompt-submit` listener installed by the in-process driver — appends one model-hidden `subagent/descriptor` event before downstream prompt admission can block or throw. Allowed admission opens the initial child turn afterward; rejected admission leaves the descriptor as a pre-turn log-only fact, and the activation's final required checkpoint persists it. The event carries no `surfaceOp`, remains outside model history, and survives when compaction replaces surface history. A known child id is resumable only when loading that child session yields a supported descriptor in the child's own suffix (after `seedLength`, so a fork seed cannot leak an ancestor's descriptor) and its header identifies the caller as the direct parent.

 The versioned descriptor (`SUBAGENT_DESCRIPTOR_VERSION` in [descriptor.ts](../../../../packages/subagent/subagent/src/descriptor.ts)) contains the subagent provider name, resolved child `agentOptions.provider` and `agentOptions.model`, and optional `persona` and `toolFilter`. It does not snapshot the merge-extensible `AgentOptions` object: unrelated extension values cannot make continuation fail merely because they are not JSON. It deliberately omits `subagentDepth`; cold resume relies on the persisted header's `delegationDepth` rather than reconstructing depth from the descriptor. `outputSchema` belongs to one activation's result contract rather than durable child composition. The child header remains authoritative for the child id, `cwd`, `parentSession`, `seedLength`, and `delegationDepth`, while the persisted child transcript owns the fork seed and subsequent history. [`delegationDepthOf()`](../../../../packages/subagent/subagent/src/index.ts) takes the maximum of header and runtime values, so reconstructed runtime options may deepen the persisted value but never lower it and a resumed child cannot regain a top-level delegation budget.
 
-Cold resume cannot depend on an optional method of the old `SubagentRun`, because that run has been disposed and is not retained across process restart. `SubagentRun` has no `resume` operation: a run represents one disposable activation and exposes only activation-scoped operations. The former `SubagentRun.sendMessage?()` capability is named `SubagentRun.steer?()` so its confirmed live-only contract cannot be confused with service orchestration or the model-facing tool.

-`SubagentControlService`'s resume path loads the known child session, folds its descriptor, authorizes the persisted `parentSession`, and runs inside the Task it creates. It passes a fully resolved request, including the Task-owned cancellation signal, to the low-level `SubagentService.resume(provider, request)`, whose only responsibility is capability-checked provider dispatch and the ordinary run lifecycle observation used by `start`. The selected `SubagentProvider.resume?()` owns transport-specific reconstruction (in-process: `parent.ctx.agents.resume` under the currently loaded parent scope) and returns a fresh run. Presence of the provider method is the continuation capability, so no redundant capability flag exists. `SubagentControlService.sendMessage()` chooses between the associated run's `steer?()` operation and this cold-resume path. Neither the low-level service nor a provider enumerates durable children or associates Tasks.
+The internal continuation manager's resume path loads the known child session, folds its descriptor, authorizes the persisted `parentSession`, and runs inside the Task it creates.

-The background tool validates and snapshots descriptor inputs before calling `TaskService.start()`. A synchronous validation failure rejects the tool call and creates no Task. The tool otherwise returns the child and Task ids immediately, without waiting for child publication or descriptor durability. In-process continuable providers perform a final session flush after the child becomes idle and before reading the result; this retries a failed loop checkpoint while the child is still live. If the final confirmation fails, the provider rejects instead of returning unconfirmed output, the control service disposes the run, and the already-created Task settles as `failed` with the durability diagnosis in its detail. Cancellation during the confirmation owns the still-unpublished activation result, so a completed child turn or a later checkpoint failure cannot replace the Task's `killed` outcome. Foreground one-shot runs retain the loop's best-effort checkpoint behavior. In-process spawn and fork reconstruct composition under the currently loaded parent scope. A fork resume loads the child's own persisted transcript, which already contains the completed-turn prefix captured at initial creation; it never forks the parent's newer history again. Resuming a parent does not eagerly resume its children.

 TODO (ACP continuation): persist the remote ACP session id as provider-specific descriptor data and implement `AcpProvider.resume?()` as spawn, initialize, `loadSession`, then prompt. The initial ACP run must verify `initialize.agentCapabilities.loadSession`, and every resumed process must use the same durable backend; replayed history from `loadSession` must not be collected as the new activation's output. Because ACP load support is negotiated per child rather than established solely by the provider method's presence, this follow-up must also define how a start result advertises child-specific continuation before ACP children enter the durable catalog.

 ## Consequences
 
 - Every follow-up after settlement pays persistence load and scoped setup cost; in exchange, live children stay bounded by concurrent work rather than historical session count. Continuable creation fails clearly when persistence is unavailable or the stored composition cannot be reconstructed.
-- Two callers may still race a stopped child through paths outside the control service. The Agent registry prevents duplicate same-session publication; a losing Task fails and its message is not delivered. A message may also race cancellation, terminal status publication, or run disposal. Admission is not claimed to be atomic or exactly-once; the synchronous process-local association install closes duplicate cold resume through the control service without a public lifecycle state machine.
-- Driving a continuable child through the ordinary Agent API bypasses its Task association. `ctx.subagents` rejects that live child as an ownership conflict; adapters must display persisted transcripts without loading an Agent and submit human input through `SubagentService.sendMessage()`.

 - The active-run association coordinates only one runtime. Concurrent resume from multiple processes is not serialized; that deployment requires a persistence-level lease or compare-and-set operation.
 - Human interaction requires the exact parent Agent instance to remain live because owner disposal cancels and removes its Tasks. It also requires an attached Task control surface. Standalone child interaction requires a future separation between Task access ownership and durable notification targeting.
 - The background tool returns child and Task ids before child publication and descriptor durability. Startup failure, a failed final durability confirmation, or process exit before the first child flush leaves the Task failed and may leave an unmaterialized or stale child id; by-id control reports missing state as unavailable rather than retroactively changing the tool acknowledgement.

 后续每个轮次都会创建另一个 Task。该轮 producer 持有的执行资源仅服务于这次激活，不属于 child 会话。它只会到达一次终态、只产生一个结果，也不会重新打开。Task 注册表中当前注册的那个存活 parent agent 实例仍是其 owner：dispose 该实例会取消、等待并移除其 Task。Task API 会授权 session id 与该 owner 匹配的调用方，但 id 相同的替代实例不会成为通知或资源清理目标。这一设计保留 `settleRun()` 契约，并使 Task 所拥有的存活 child 数量受并发工作量限制，而不是随历史会话数量增长。
 
-用户界面适配器打开 child 会话时，只读取持久化 transcript，不会仅为展示而恢复 agent。用户输入通过控制服务，启动或加入与 parent 输入相同的 Task 激活。由用户启动的 Task 会保留当前加载的精确 parent Agent 作为通知目标，`task_output` 仍是唯一结果路径。只要 Task 尚未标记为已报告，现有完成监听器最多注入一条主动通知；`kill`、终态读取或终态等待都可能将其标记为已报告，并抑制这条通知。因此，仅允许在该 parent 实例保持存活时进行用户交互。可以比 parent 存活更久、并将结论显式合并回去的用户自有会话属于[交互式 side session](../../proposed/feature/2026-07-08-interactive-side-sessions.md)，不属于这一由 Task 持有的生命周期。

 ### 活跃 run 关联

-每个可继续 child 轮次都通过这条由 Task 支撑的路径准入。非终态 Task 是唯一受支持的存活激活；不存在激活时，其 run 已被 dispose，持久化 child 可以恢复。在路由任何按 id 的操作之前，控制服务会同步将自身关联与 `ctx.agents.get(childId)` 比较。如果注册表中的 Agent 没有关联，或者它与所关联的 `run.localAgent` 不同，就属于所有权冲突：控制服务会失败，而不会接管 idle Agent 或附加未受跟踪的轮次。二者均不存在时，可以从持久化存储恢复；如果检查后又有竞争方发布，仍会在 Agent 注册表的冲突边界上失败。

-系统依据 Task 关联进行路由。运行中的 Task 通过 run 可选且提供确认语义的 `SubagentRun.steer` 功能接收在线消息。Task 不存在时，系统创建新 Task，并从持久化存储恢复 child。进程内 spawn 和 fork 会先同步要求 child 处于 `running` 状态，并拒绝已经提交结构化捕获的 child；随后调用 `Agent.steer()`，等待该消息专属的准入回执。默认循环会为每个 steering 项目提供一份归属于该消息的回执；只有在 `agent/pre-step` 成功后追加该消息、捕获不可变的请求历史并提交 `step/start`，回执才会解析为 `admitted`。终止型轮次策略、取消和 dispose（资源释放）会将待处理回执解析为 `rejected`。非终止型轮次关闭可以把待处理 steering 带入后续排队轮次，但不会确认其准入。提供方必须在调用 `Agent.steer()` 前检查存活状态，避免其 idle 路径在观察到的 run 之外启动轮次。如果查找关联之后、请求获准之前，Task 结算或终止策略率先完成，`steer()` 会拒绝，`send_message` 会报告消息未送达，而且该次调用不会改用从持久化存储恢复路径；在 Task 终态发布后重试，才可能启动下一次激活。

 ## Problem
 
 Continuable-child orchestration originally lived in a separate `ctx.subagentControl` service above the raw `ctx.subagents` provider seam. That split kept provider dispatch independent of Tasks and persistence, and gave model and human adapters one orchestration contract. In practice the two services described one capability family, every continuable caller needed both, and the provider-bound delegation tool had to infer policy from `provider.resume` and inspect whether the control service and `send_message` tool happened to be loaded. This made sibling plugin presence decide execution semantics and coupled starting continuable work to an optional follow-up surface.
 
 ## Decision
 
-`SubagentService` is the only public service. It retains raw `start(name, request)` and `resume(name, request)` for callers that own run collection, and exposes `startContinuable(spec)` and `sendMessage(...)` for durable Task-backed activations.

 ## 问题
 
 可继续 child 的编排最初位于原始 `ctx.subagents` 提供方 seam 之上的独立 `ctx.subagentControl` 服务中。该拆分使提供方分发与 Task 和持久化无关，并为模型与人工适配器提供统一的编排契约。实践中，两个服务属于同一组功能，每个可继续调用方都需要二者，而绑定提供方的委派工具必须根据 `provider.resume` 推断策略，并检查控制服务与 `send_message` 工具是否碰巧已加载。如此一来，配套插件是否存在会决定执行语义，并将可继续工作的启动耦合到可选的后续操作接口。
 
 ## 决策

+
+## Problem
+
+Merging continuable-child orchestration into `ctx.subagents` left provider dispatch and caller intent on the same public service. `resume(name, request)` accepted a descriptor, authorized parent, durable child id, and activation signal that only the internal continuation manager could resolve correctly. `sendMessage(...)` exposed transport wording rather than the `followup` intent already used by `Agent`, and its separate source and signal parameters widened an operation every caller had to use atomically.
+
+The durability boundary also exposed both `SessionStore.flush()` and `flushRequired()`. They performed the same scoped parallel dispatch and differed only in whether an empty listener snapshot was accepted, so the session interface encoded one consumer's policy as a second operation.
+
+## Decision
+
+`SubagentService` exposes three execution intents: `start(name, request)` for an ordinary holder-owned run, `startContinuable(spec)` for a durable Task-backed child, and `followup(parent, childId, content, { source, signal })` for later content. The last verb matches `Agent.followup()`, while `SubagentRun.steer()` remains the narrower confirmed live-activation capability. The model-facing tool keeps its stable `send_message` name and delegates routing to `followup()`.
+
+Caller and provider requests are distinct. `SubagentStartRequest` contains only caller-supplied start data; `SubagentProviderStartRequest` adds service-resolved continuation state. Ordinary `start()` clears that state before provider dispatch. `SubagentProviderResumeRequest` remains part of the provider seam, but `SubagentService.resume()` is absent: the continuation manager loads the descriptor, authorizes the parent, and invokes private provider start/resume closures owned by the service. Provider dispatch still receives the same capability checks and run lifecycle observation without becoming a caller operation.
+
+`SessionStore.flush(session)` returns `Promise`. It resolves `true` after at least one scoped durability listener participates successfully, resolves `false` for an empty listener snapshot, and rejects with the first registered listener failure after all listeners settle. Ordinary checkpoints may ignore the boolean. A continuable provider requires `true` at its final result boundary and maps `false` or rejection to `DURABILITY_FAILED`.
+
+## Alternatives considered
+
+**Keep public provider resume dispatch.** No production caller outside the continuation manager owns the descriptor lookup, direct-parent authorization, Task cancellation, and activation association needed to call it safely. A public method would expose resolved implementation data without a valid independent intent.
+
+**Keep `sendMessage` on the service.** The model tool sends a message, but the service operation represents a follow-up that may steer or cold-resume. `followup` aligns with the structural `Agent` interface and does not promise a particular route.
+
+**Keep `flushRequired()`.** A second method hides only an empty-listener check. Returning participation from the existing barrier keeps dispatch in one implementation and lets each caller state whether absence is acceptable.
+
+**Fold ordinary and continuable starts together.** A flag would make one method return either an awaited holder-owned run or immediate child/Task identities. Separate intent methods preserve the ownership and timing distinction without a return union.
+
+## Consequences
+
+- The Cordis service catalog contains only caller operations; provider reconstruction remains extensible through `SubagentProvider.resume?()` without exposing its resolved request as a service method.
+- Follow-up source and cancellation travel in one options object, matching the intent-helper shape on `Agent` while retaining the existing live-delivery and cold-resume semantics.
+- Session durability has one barrier operation. Callers that require a backend must inspect its participation result rather than selecting a second dispatch method.
+- The `send_message` schema, route results, Task ownership, durable event vocabulary, and model-visible transcript remain unchanged.

+# Agent Note: 按意图命名的 subagent 继续执行操作
+
+Status: implemented
+
+[English](2026-07-27-intent-named-subagent-continuation-operations.md) | 中文
+
+## 问题
+
+将可继续 child 的编排合并到 `ctx.subagents` 后，提供方分发与调用方意图共存于同一个公开服务中。`resume(name, request)` 接受描述符、已鉴权的 parent、持久化 child id 与激活信号，而只有内部继续执行管理器才能正确解析这些数据。`sendMessage(...)` 暴露的是传输层措辞，而不是 `Agent` 已采用的 `followup` 意图；它还将来源与信号拆成独立参数，扩大了操作接口，而每个调用方都必须以原子方式同时使用二者。
+
+持久性边界还同时公开了 `SessionStore.flush()` 与 `flushRequired()`。二者执行相同的作用域内并行分发，唯一差别是是否接受空的监听器快照，因此会话接口将一个消费方的策略编码为第二项操作。
+
+## 决策
+
+`SubagentService` 公开三种执行意图：`start(name, request)` 用于普通的、由持有方负责的 run；`startContinuable(spec)` 用于具备持久性且由 Task 支撑的 child；`followup(parent, childId, content, { source, signal })` 用于投递后续内容。最后一个动词与 `Agent.followup()` 一致，而 `SubagentRun.steer()` 仍是范围更窄的能力，仅向已确认仍在运行的激活提供 steering（中途引导）。面向模型的工具保留稳定的 `send_message` 名称，并将路由委托给 `followup()`。
+
+调用方请求与提供方请求相互分离。`SubagentStartRequest` 只包含调用方提供的启动数据；`SubagentProviderStartRequest` 则加入由服务解析的继续执行状态。普通 `start()` 在分发给提供方之前会清除该状态。`SubagentProviderResumeRequest` 仍属于提供方 seam，但 `SubagentService.resume()` 不对外公开：继续执行管理器加载描述符、对 parent 进行鉴权，并调用由服务持有的私有提供方启动与恢复闭包。提供方分发仍会经过相同的功能检查和 run 生命周期观测，而无需将其变成调用方操作。
+
+`SessionStore.flush(session)` 返回 `Promise`。至少一个作用域内的持久性监听器成功参与后，它解析为 `true`；监听器快照为空时解析为 `false`；所有监听器结算后，如有失败，则以注册顺序最靠前的监听器错误拒绝。普通检查点可以忽略该布尔值。可继续提供方在最终结果边界要求该值为 `true`，并将 `false` 或拒绝映射为 `DURABILITY_FAILED`。
+
+## 已考虑的替代方案
+
+**保留公开的提供方恢复分发。** 继续执行管理器之外没有任何生产调用方负责安全调用所需的描述符查找、直接 parent 鉴权、Task 取消与激活关联。公开方法会暴露已解析的实现数据，但并不存在与之对应的合理独立调用意图。
+
+**在服务上保留 `sendMessage`。** 面向模型的工具发送消息，但服务操作表达的是后续操作，既可能对运行中的激活执行 steering，也可能从持久化存储恢复。`followup` 与结构化 `Agent` 接口保持一致，也不承诺特定路由。
+
+**保留 `flushRequired()`。** 第二个方法只封装了空监听器检查。由现有屏障返回是否有监听器参与，可以让分发只保留一套实现，并让每个调用方自行判定缺少监听器是否可接受。
+
+**合并普通启动与可继续启动。** 一个标志会让同一方法要么等待由持有方负责的 run 就绪后返回，要么立即返回 child 和 Task 标识。按意图拆分的方法无需返回值联合类型即可保留所有权与时序差异。
+
+## 影响
+
+- Cordis 服务目录只包含调用方操作；提供方的重建能力仍可通过 `SubagentProvider.resume?()` 扩展，同时不会将已解析的请求暴露为服务方法。
+- 后续操作的来源与取消信号通过同一个选项对象传递，与 `Agent` 上按意图命名的辅助方法形态一致，同时保留在线投递与从持久化存储恢复的语义。
+- 会话持久性只保留一个屏障操作。需要后端参与的调用方必须检查参与结果，而不是选择第二种分发方法。
+- `send_message` schema、路由结果、Task 所有权、持久化事件词汇与模型可见的 transcript（文本记录）保持不变。

+A **continuable background subagent** is a durable child session with a series of Task-backed activations. `SubagentService.startContinuable()` allocates the stable child id, snapshots the versioned `subagent/descriptor` payload, and passes both through the provider-facing start request; the provider publishes exactly that id and appends the descriptor before the initial prompt is admitted. `SubagentService.followup()` mirrors the intent verb on `Agent`: it steers a live activation or privately dispatches a resolved provider resume after loading and authorizing a stopped child.

 ### Public API
 
 - `ctx.sessions.create(id?, { seed?, meta? }?)` validates and detaches durable seed/header data, fills the version and id, defaults `createdAt` to now, publishes the session, and binds it to the calling fiber. Persisted reconstruction supplies its original `createdAt`, `seedLength`, and `delegationDepth`.
-- `ctx.sessions.flush(session)` dispatches the awaited parallel durability checkpoint through the session's captured scope. Every listener starts and the call waits for all to settle before reporting failure; unpublished, detached, and stale objects reject.
-- `ctx.sessions.flushRequired(session)` uses the same dispatch but also rejects an empty scoped listener snapshot. Callers use it when success requires an installed durability participant rather than optional best-effort persistence.
+- `ctx.sessions.flush(session)` dispatches the awaited parallel durability checkpoint through the session's captured scope. Every listener starts and the call waits for all to settle before reporting failure; it returns `true` when at least one listener participated and `false` for an empty snapshot, while unpublished, detached, and stale objects reject. A caller that requires durable storage rejects `false` at its own policy boundary.
 - `findLastMessageTurnEnd(events)` pairs message-triggered starts with their ends and returns the latest matched `turn/end`. Outcome consumers use this fold instead of the raw latest log event because between-turn records and non-message turns have no prompt outcome.
 - `ctx.sessions.fork(source, boundary?, childSessionId?): Session` — Resolve a live session object or id, select a seed through the inclusive `boundary` event seq (default: current last event), require that prefix to end outside an open turn, and create a live child session with lineage metadata.

-- `ctx.sessions.flushRequired(session)` 沿用相同的分发逻辑，但也会拒绝空的作用域监听器快照。若成功要求已安装的持久性参与方介入，而不是采用可选的尽力持久化，调用方应使用此方法。
+- `ctx.sessions.flush(session)` 通过会话捕获的作用域分发受等待的并行持久性检查点。每个监听器都会启动；调用会等待全部结算后才报告失败；至少一个监听器参与时返回 `true`，监听器快照为空时返回 `false`，而未发布、已脱离和陈旧的对象会被拒绝。要求持久化存储的调用方应在自己的策略边界拒绝 `false`。
 - `findLastMessageTurnEnd(events)` 将由消息触发的开始与结束配对，并返回最近匹配的 `turn/end`。结果消费方使用该折叠逻辑，而不直接取日志中最近的事件，因为轮次间记录和非消息轮次没有提示词结果。
 - `ctx.sessions.fork(source, boundary?, childSessionId?): Session`：解析实时会话对象或 id，选取截至 `boundary` 事件序号（含该事件）的种子（默认为当前最后一个事件），要求所选前缀结束时没有开放轮次，再创建带谱系元数据的实时子会话。

 | Member | Meaning |
 |---|---|
 | `registerProvider(provider)` | Register one trusted same-process implementation by name. Registration is effect-scoped; removing it prevents new starts but does not revoke runs already returned to callers. Duplicate names fail loud. |
 | `getProvider(name)` | Return the provider, or `undefined` when absent. |
 | `list()` | Return provider names in insertion order. |
-| `start(name, request)` | Validate requested capabilities and semantic values, then await the provider until a real child is ready. Fulfillment returns a holder-owned `SubagentRun`; rejection means the provider has already cleaned every partial startup resource. |
-| `resume(name, request)` | Capability-checked raw dispatch to `provider.resume?()` with the same run lifecycle observation as `start`; the caller owns descriptor lookup, authorization, and collection. |
+| `start(name, request)` | Validate an ordinary caller request, then await the provider until a real child is ready. Fulfillment returns a holder-owned `SubagentRun`; rejection means the provider has already cleaned every partial startup resource. Continuation state cannot enter through this operation. |
 | `startContinuable(spec)` | Allocate a durable child id and register its initial Task-backed activation. Requires `ctx.tasks`, `ctx.agents`, session persistence, and a resumable provider. |
-| `sendMessage(parent, childId, message, source, signal)` | Steer the current activation or start a new Task that cold-resumes the durable child. Aborting `signal` while live delivery awaits admission cancels the shared activation and rejects after it reaches quiescence. Requires `ctx.tasks` and `ctx.agents`; cold resume also requires session persistence. |
+| `followup(parent, childId, content, { source, signal })` | Follow up with a durable child, matching `Agent.followup()` terminology.

Requires `ctx.tasks` and `ctx.agents`; cold resume also requires session persistence. |

 ## Ownership and lifecycle
 
-`provider.start(request): Promise` is the ownership-transfer boundary. Before fulfillment, the provider owns setup and must cancel, roll back, and quiesce partial resources on every failure. After fulfillment, the caller owns the run and must call `dispose()` on every path. `provider.resume?(request)` shares the same contract for a resumed activation.
+`provider.start(request): Promise` is the ownership-transfer boundary. Before fulfillment, the provider owns setup and must cancel, roll back, and quiesce partial resources on every failure. After fulfillment, the caller owns the run and must call `dispose()` on every path. `provider.resume?(request)` shares the same contract for a resumed activation; only the continuation manager dispatches it.
 
 `SubagentRun.result` resolves to `{ output, structured?, stopReason }`. Child-level failures resolve with a non-`completed` reason; only an infrastructure fault that the seam cannot represent may reject. For a continuable activation, a completed result also confirms that the provider made its final state durable; a failed required checkpoint rejects as infrastructure rather than publishing unconfirmed output. `dispose()` is idempotent, cancels remaining work, and waits for the child resources to quiesce.
 
 A local run publishes an ordinary child agent/session before `start()` fulfills, returns that shared session id as `SubagentRun.id`, exposes the exact child as `SubagentRun.localAgent`, and records `request.parent.session.id` in the child's `parentSession` header. A continuable start publishes exactly the service-allocated `continuation.sessionId`. Remote providers instead mint a parent-scoped lifecycle id and return `localAgent: undefined`.
 
-The service emits `subagent/start` only after `start()` or `resume()` has fulfilled. It attaches the result observer before that synchronous notification, so even an already-settled child still produces `subagent/start` before `subagent/end`. The pair shares a service-minted `runId`; its `local` flag is snapshotted from the provider's exact `localAgent`, so observers never infer run identity or locality from reusable provider/session names.

 Run events are scoped to the delegating parent. Every listener is independently contained: a synchronous throw or rejected returned promise is logged without starving peer listeners or changing the run.

 | 成员 | 含义 |
 |---|---|
 | `registerProvider(provider)` | 按名称注册一个可信的同进程实现。注册受 effect 作用域约束；移除注册会阻止新的启动，但不会撤销已返回给调用方的运行。重复名称会立即失败。 |
 | `getProvider(name)` | 返回提供方；不存在时返回 `undefined`。 |
 | `list()` | 按插入顺序返回提供方名称。 |
-| `start(name, request)` | 校验请求的能力和语义值，然后等待提供方，直到真实子 agent 就绪。兑现时返回由持有方拥有的 `SubagentRun`；拒绝表示提供方已清理所有局部启动资源。 |
-| `resume(name, request)` | 在功能检查后将底层请求分发给 `provider.resume?()`，并沿用与 `start` 相同的运行生命周期观察；描述符查找、授权与收集由调用方负责。 |
+| `start(name, request)` | 校验普通调用方请求，然后等待提供方，直到真实子 agent 就绪。兑现时返回由持有方拥有的 `SubagentRun`；拒绝表示提供方已清理所有局部启动资源。此操作不允许传入继续执行状态。 |
 | `startContinuable(spec)` | 分配持久化子 agent id，并注册其初始的由 Task 支撑的激活。要求 `ctx.tasks`、`ctx.agents`、会话持久化及可恢复的提供方。 |
-| `sendMessage(parent, childId, message, source, signal)` | 引导当前激活，或启动新 Task 从持久化存储恢复子 agent。若在在线投递等待准入期间中止 `signal`，则会取消共享激活，并在其完全停稳后拒绝该调用。要求 `ctx.tasks` 和 `ctx.agents`；从持久化存储恢复还要求会话持久化。 |

 `SubagentRun.result` 兑现为 `{ output, structured?, stopReason }`。子 agent 级失败会以非 `completed` 原因兑现；只有 seam 无法表示的基础设施故障才可以拒绝。对于可继续激活，完成的结果还会确认提供方已使其最终状态具备持久性；必需检查点失败会作为基础设施故障拒绝，而不会发布未经确认的输出。`dispose()` 是幂等的，会取消剩余工作，并等待子 agent 资源完全停稳。
 
 本地运行会在 `start()` 兑现前发布普通的子 agent/会话，把该共享会话 id 作为 `SubagentRun.id` 返回，以 `SubagentRun.localAgent` 公开准确的子 agent，并把 `request.parent.session.id` 记录到子 agent 的 `parentSession` header。可继续启动会准确发布由服务分配的 `continuation.sessionId`。远程提供方则生成父级作用域的生命周期 id，并返回 `localAgent: undefined`。
 
-服务只会在 `start()` 或 `resume()` 兑现后发出 `subagent/start`。它在同步通知前附加结果观察器，因此即使子 agent 已经结算，也仍会先产生 `subagent/start`，再产生 `subagent/end`。这对事件共享服务生成的 `runId`；其 `local` 标志取自提供方准确 `localAgent` 的快照，因此观察器绝不会从可复用的提供方/会话名称推断运行身份或本地性。

Provider-bound `@deepseek-ai/dsh-tool-subagent` instances register distinct delegation tools per transport; this separately loaded package registers one shared follow-up tool, so multiple delegation tools never register duplicate global controls. Its presence does not determine whether a delegation tool starts continuable work.
 
 The tool performs no lifecycle routing. It attributes every follow-up as `{ kind: 'coordinator', senderSessionId: parent.id }`; the subagent service preserves that source while deciding between live delivery to the running activation's existing Task and a fresh Task that cold-resumes the durable child. The tool forwards its execution signal, so cancellation while live delivery awaits admission cancels the shared activation and settles only after the child reaches quiescence. The tool renders which route was taken and the relevant Task id. A delivery failure becomes an errored tool result stating the message was not delivered.

 本工具不执行生命周期路由。它将每条后续消息的来源标记为 `{ kind: 'coordinator', senderSessionId: parent.id }`；subagent 服务会保留该来源，并在向运行中激活的现有 Task 在线投递消息与创建新 Task、从持久化存储恢复子 agent 之间做出选择。本工具会转发其执行信号，因此，若在在线投递等待准入期间取消，则会取消共享激活，并仅在子 agent 完全停稳后结算。本工具会渲染实际采用的路由及相关 Task id。投递失败会变为出错的工具结果，并明确说明消息未送达。

Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.\n\nUse the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.\n\n## Writing code for run_code\n\nPass `run_code` the body of an async TypeScript function (erasable syntax only — no `enum` or namespaces; type annotations are advisory, the code runs type-stripped). Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Independent read-only calls MAY overlap under `Promise.all` (safe calls run concurrently; mutating calls run alone, in submission order). Sequence dependent work with `await`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ntype JsonValue = null | boolean | number | string | JsonValue[] | { [key: string]: JsonValue }\n\ninterface ToolArgsMap {\n  /** Execute a bash command (`bash -c`) and return its stdout/stderr.

It does not create files, install a package, change cordis.yml or personal/project config, survive restart, or automatically become permanent. To keep it, ask the Agent to implement a normal local, project, or repository Plugin through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime. */\n  cordis_mount: {\n    /** JavaScript body returning a temporary Plugin; evaluated now and saved nowhere. */\n    code: string;\n  } & Record;\n  /** Unmount a current-process temporary Plugin created by cordis_mount.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn. The workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result. Script-body hooks: - `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly. - `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages. - `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`. - `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim. Misused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`. Constraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn.\n\nThe workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

Your working directory is {{cwd}}.\n\nVerify your work by running the code or tests. Keep answers brief and factual.\n\n\nUse the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.\n\nUse the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.\n\nCheck the [exit code: N] marker on every bash result; investigate failures before moving on.\n\nTrack every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.\n\nUse the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.\n\n## Writing code for run_code\n\nPass `run_code` the body of an async TypeScript function (erasable syntax only — no `enum` or namespaces; type annotations are advisory, the code runs type-stripped). Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Independent read-only calls MAY overlap under `Promise.all` (safe calls run concurrently; mutating calls run alone, in submission order). Sequence dependent work with `await`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ntype JsonValue = null | boolean | number | string | JsonValue[] | { [key: string]: JsonValue }\n\ninterface ToolArgsMap {\n  /** Execute a bash command (`bash -c`) and return its stdout/stderr.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn. The workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result. Script-body hooks: - `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`).

Anything else (`effort`/`isolation`/`agentType`) is rejected loudly. - `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages. - `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`. - `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim. Misused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`. Constraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

This creates an in-memory runtime Plugin, not an installed or configured Plugin. It remains active across later turns until cordis_unmount, toolset unload, or DSH restart. It does not create files, install a package, change cordis.yml or personal/project config, survive restart, or automatically become permanent. To keep it, ask the Agent to implement a normal local, project, or repository Plugin through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime.","parameters":{"type":"object","properties":{"code":{"type":"string","description":"JavaScript body returning a temporary Plugin; evaluated now and saved nowhere."}},"required":["code"]}},{"name":"cordis_unmount","description":"Unmount a current-process temporary Plugin created by cordis_mount.

Your working directory is {{cwd}}.\n\nVerify your work by running the code or tests. Keep answers brief and factual.\n\n\nUse the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.\n\nUse the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.\n\nCheck the [exit code: N] marker on every bash result; investigate failures before moving on.\n\nTrack every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.\n\nUse the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.\n\n## Writing code for run_code\n\nPass `run_code` the body of an async TypeScript function (erasable syntax only — no `enum` or namespaces; type annotations are advisory, the code runs type-stripped). Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Independent read-only calls MAY overlap under `Promise.all` (safe calls run concurrently; mutating calls run alone, in submission order). Sequence dependent work with `await`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ntype JsonValue = null | boolean | number | string | JsonValue[] | { [key: string]: JsonValue }\n\ninterface ToolArgsMap {\n  /** Execute a bash command (`bash -c`) and return its stdout/stderr.

This creates an in-memory runtime Plugin, not an installed or configured Plugin. It remains active across later turns until cordis_unmount, toolset unload, or DSH restart. It does not create files, install a package, change cordis.yml or personal/project config, survive restart, or automatically become permanent. To keep it, ask the Agent to implement a normal local, project, or repository Plugin through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime. */\n  cordis_mount: {\n    /** JavaScript body returning a temporary Plugin; evaluated now and saved nowhere. */\n    code: string;\n  } & Record;\n  /** Unmount a current-process temporary Plugin created by cordis_mount.

This creates an in-memory runtime Plugin, not an installed or configured Plugin. It remains active across later turns until cordis_unmount, toolset unload, or DSH restart. It does not create files, install a package, change cordis.yml or personal/project config, survive restart, or automatically become permanent. To keep it, ask the Agent to implement a normal local, project, or repository Plugin through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime.","parameters":{"type":"object","properties":{"code":{"type":"string","description":"JavaScript body returning a temporary Plugin; evaluated now and saved nowhere."}},"required":["code"]}},{"name":"cordis_unmount","description":"Unmount a current-process temporary Plugin created by cordis_mount.

An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn. The workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result. Script-body hooks: - `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly. - `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages. - `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`. - `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim. Misused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`. Constraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn.\n\nThe workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise` — run one subagent to completion.

Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

Your working directory is {{cwd}}.\n\nVerify your work by running the code or tests. Keep answers brief and factual.\n\n\nUse the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.\n\nUse the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.\n\nCheck the [exit code: N] marker on every bash result; investigate failures before moving on.\n\nTrack every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.\n\nUse the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.\n\n## Writing code for run_code\n\nPass `run_code` the body of an async TypeScript function (erasable syntax only — no `enum` or namespaces; type annotations are advisory, the code runs type-stripped). Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Independent read-only calls MAY overlap under `Promise.all` (safe calls run concurrently; mutating calls run alone, in submission order). Sequence dependent work with `await`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ntype JsonValue = null | boolean | number | string | JsonValue[] | { [key: string]: JsonValue }\n\ninterface ToolArgsMap {\n  /** Execute a bash command (`bash -c`) and return its stdout/stderr.

It does not create files, install a package, change cordis.yml or personal/project config, survive restart, or automatically become permanent. To keep it, ask the Agent to implement a normal local, project, or repository Plugin through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn. The workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result. Script-body hooks: - `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object.

Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages. - `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`. - `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim. Misused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.

This creates an in-memory runtime Plugin, not an installed or configured Plugin. It remains active across later turns until cordis_unmount, toolset unload, or DSH restart. It does not create files, install a package, change cordis.yml or personal/project config, survive restart, or automatically become permanent. To keep it, ask the Agent to implement a normal local, project, or repository Plugin through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime.","parameters":{"type":"object","properties":{"code":{"type":"string","description":"JavaScript body returning a temporary Plugin; evaluated now and saved nowhere."}},"required":["code"]}},{"name":"cordis_unmount","description":"Unmount a current-process temporary Plugin created by cordis_mount.

Your working directory is {{cwd}}.\n\nVerify your work by running the code or tests. Keep answers brief and factual.\n\n\nUse the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.\n\nUse the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.\n\nCheck the [exit code: N] marker on every bash result; investigate failures before moving on.\n\nTrack every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.\n\nUse the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.\n\n## Writing code for run_code\n\nPass `run_code` the body of an async TypeScript function (erasable syntax only — no `enum` or namespaces; type annotations are advisory, the code runs type-stripped). Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Independent read-only calls MAY overlap under `Promise.all` (safe calls run concurrently; mutating calls run alone, in submission order). Sequence dependent work with `await`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ntype JsonValue = null | boolean | number | string | JsonValue[] | { [key: string]: JsonValue }\n\ninterface ToolArgsMap {\n  /** Execute a bash command (`bash -c`) and return its stdout/stderr.

This creates an in-memory runtime Plugin, not an installed or configured Plugin. It remains active across later turns until cordis_unmount, toolset unload, or DSH restart. It does not create files, install a package, change cordis.yml or personal/project config, survive restart, or automatically become permanent. To keep it, ask the Agent to implement a normal local, project, or repository Plugin through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime. */\n  cordis_mount: {\n    /** JavaScript body returning a temporary Plugin; evaluated now and saved nowhere. */\n    code: string;\n  } & Record;\n  /** Unmount a current-process temporary Plugin created by cordis_mount.

This creates an in-memory runtime Plugin, not an installed or configured Plugin. It remains active across later turns until cordis_unmount, toolset unload, or DSH restart. It does not create files, install a package, change cordis.yml or personal/project config, survive restart, or automatically become permanent. To keep it, ask the Agent to implement a normal local, project, or repository Plugin through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` VETOES the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime.","parameters":{"type":"object","properties":{"code":{"type":"string","description":"JavaScript body returning a temporary Plugin; evaluated now and saved nowhere."}},"required":["code"]}},{"name":"cordis_unmount","description":"Unmount a current-process temporary Plugin created by cordis_mount.

Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

Keep answers brief and\nfactual.\n\n\nUse the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.\n\nUse the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.\n\nCheck the [exit code: N] marker on every bash result; investigate failures before moving on.\n\nUse a terminal session only when work needs persistent terminal state or interactive stdin; prefer bash/read/write/edit for bounded one-shot operations. Track every terminal session id and close sessions that no longer matter. An inferred_idle or timeout result does not prove the foreground command exited.\n\nTrack every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.\n\nUse the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution.

Subject: [PATCH 359/557] fix(fs-search): platform-normalize sampling test
 paths

The sampler and the workdir-relative display conversion group by
node:path.sep, so the POSIX-style '/' literals in the cross-directory
sampling cases collapse into per-path groups on Windows (every path its
own top-level entry), turning the round-robin sample into a head. The
same gap exists on master (its platform-separator fix predates these
tests); normalize the literals through a platform helper instead, and
keep the POSIX-backslash-as-filename case Windows-skipped as before.

 listing assertion paths

The view listing carries absolute display paths, so the POSIX-style
'node_modules_old/kept.js' substring assertions only match on Linux
(Windows display paths use backslashes). Assert with platform separators
to keep the same check meaningful on Windows; the pre-existing gap is
identical on master.

+# Agent Note: Todo-first composer context order
+
+Status: implemented

+English | [中文](2026-08-02-todo-first-composer-context-order.zh.md)
+
+## Problem
+
+The composer context stack rendered Goal before Todo even though the Harness design orders the current task plan before its ongoing goal and pending Queue. Todo also used the Queue wrapper's 776px width as its visible card width, while Goal and the Queue panel rendered on the shared 752px card column. The result inverted the intended information hierarchy and left Todo wider than both adjacent panels.
+
+## Decision
+
+The `conversation.input.dock` list uses one ascending product order: Todo at `0`, Goal at `10`, and Queue at `20`, followed by the composer bar outside the list. Registration order remains the semantic source of truth; the renderer does not hardcode known component ids or repair their order with CSS.
+
+Todo, Goal, and the visible Queue panel share the 752px card column inside the 800px composer cap. Queue retains a 776px wrapper with 12px transparent inset on each side because that wrapper owns the composer overlap. Todo is a standalone card rather than a wrapper, so its maximum width subtracts both inset layers directly and exposes the same left and right edges as Goal and the Queue panel.
+
+The [composer stack contract](2026-07-30-composer-context-stack-order.md) continues to own inter-card spacing and Queue's exclusive overlap with the composer. This decision supersedes only that note's Goal-first order.
+
+## Verification
+
+Todo and Goal registration tests pin orders `0` and `10`; Queue remains pinned at `20`. The keyless Queue browser scenario renders all three panels concurrently, records their Todo–Goal–Queue accessibility order, and compares their visible bounding boxes at the desktop viewport before exercising Queue mutations.
+
+## Alternatives considered
+
+**Reorder the known panels inside `ConversationRoot`.** Rejected because `conversation.input.dock` is an extensible ordered list; a hardcoded component inventory would make plugin activation order and rendered order disagree.
+
+**Use CSS `order` to move Todo visually.** Rejected because accessibility and keyboard order must match the visual hierarchy, and the slot ledger already owns semantic order.
+
+**Keep Todo at the Queue wrapper width.** Rejected because the Queue wrapper's transparent inset is layout infrastructure for its composer overlap, not part of the visible panel column.
+
+## Consequences
+
+The standing task plan appears before the ongoing goal, pending Queue work remains closest to the composer, and all three visible cards share one horizontal edge. Future input-dock plugins choose an explicit position relative to Todo `0`, Goal `10`, and Queue `20`; only Queue owns the terminal wrapper overlap.

+# Agent Note: Todo 优先的 composer 上下文顺序
+
+Status: implemented
+
+[English](2026-08-02-todo-first-composer-context-order.md) | 中文
+
+## 问题
+
+composer 上下文堆栈将 Goal 渲染在 Todo 之前，但 Harness 设计稿把当前任务计划排在进行中的目标和待处理 Queue 之前。Todo 还把 Queue 包装层的 776px 宽度用作自身的可见卡片宽度，而 Goal 和 Queue 面板则渲染在共享的 752px 卡片列上。结果既颠倒了预期的信息层级，也让 Todo 比相邻两个面板更宽。
+
+## 决策
+
+`conversation.input.dock` 列表采用统一的产品顺序，升序依次为 Todo `0`、Goal `10`、Queue `20`，随后是位于列表外的 composer bar。注册顺序仍是语义真源；渲染器不会硬编码已知组件 id，也不会使用 CSS 修正它们的顺序。
+
+Todo、Goal 与可见的 Queue 面板共用 800px composer 宽度上限内的 752px 卡片列。Queue 保留 776px 包装层，并在两侧各留 12px 透明内缩，因为该包装层负责与 composer 重叠。Todo 是独立卡片，而非包装层，因此其最大宽度会直接扣除两层内缩，使左右边缘与 Goal 和 Queue 面板一致。
+
+[composer 堆栈契约](2026-07-30-composer-context-stack-order.md)继续规定卡片间距，以及仅限 Queue 与 composer 重叠。本决策只取代该记录中 Goal 优先的顺序。
+
+## 验证
+
+Todo 与 Goal 的注册测试分别固定顺序 `0` 和 `10`；Queue 仍固定为 `20`。无密钥 Queue 浏览器场景同时渲染三个面板，记录 Todo–Goal–Queue 的无障碍顺序，并在桌面视口下比较其可见边界框，随后再执行 Queue 变更。
+
+## 考虑过的替代方案
+
+**在 `ConversationRoot` 内重新排列已知面板。** 不予采纳，因为 `conversation.input.dock` 是可扩展的有序列表；硬编码的组件清单会使插件激活顺序与渲染顺序不一致。
+
+**使用 CSS `order` 移动 Todo 的视觉位置。** 不予采纳，因为无障碍顺序和键盘顺序必须与视觉层级一致，而 slot 账本已经负责语义顺序。
+
+**让 Todo 保持 Queue 包装层的宽度。** 不予采纳，因为 Queue 包装层的透明内缩是其与 composer 重叠所需的布局基础设施，不属于可见面板列。
+
+## 后果
+
+当前有效的任务计划显示在进行中的目标之前，待处理 Queue 工作仍最靠近 composer，三张可见卡片共用相同的横向边缘。未来的 input-dock 插件必须相对于 Todo `0`、Goal `10` 和 Queue `20` 选择明确位置；仅 Queue 负责末端包装层与 composer 的重叠。

 ## Decision
 
-`GoalBar` (`packages/client/ui-goal/src/client/GoalBar.tsx`) is a props-driven, self-contained component registered first in the composer's input-dock list. Its standalone 752px card follows the composer's horizontal geometry, and every visible state shares one fixed 36px height so switching phases never resizes it. Loading (`goal === undefined`), absent (`goal === null`), and `phase === 'complete'` render nothing — a completed goal is history, not chrome.
+`GoalBar` (`packages/client/ui-goal/src/client/GoalBar.tsx`) is a props-driven, self-contained component registered second in the composer's input-dock list, after Todo and before Queue. Its standalone 752px card follows the composer's horizontal geometry, and every visible state shares one fixed 36px height so switching phases never resizes it. Loading (`goal === undefined`), absent (`goal === null`), and `phase === 'complete'` render nothing — a completed goal is history, not chrome.
 
 Visibility drives the label and actions: active shows "Ongoing Goal" with pause/edit/clear; paused shows "Paused Goal" and swaps pause for a resume icon button; blocked shows "Blocked Goal" and carries `blockedReason.message` as the strip's `title` tooltip. Goal creation lives on the `/goal` command, not in the bar. The pencil swaps the strip for an inline edit form prefilled with the current objective: Enter or the check button saves through `GoalBarActions.onEdit(objective)`, Esc cancels, and an all-whitespace objective keeps save disabled. The form closes only when the edit succeeds; a failure preserves the draft and displays the error in the bar. Resume and clear failures are displayed there as well. Clear otherwise calls `onClear` directly with no confirmation — a clear keeps a durable tombstone, so nothing is unrecoverable. Every mutation first acquires a synchronous component-local single-flight latch because React's pending-state render cannot close the same-frame click window. A successful clear also suppresses that exact goal id immediately while the authoritative null projection catches up, so an acknowledged tombstone cannot leave a stale clear control that submits `GOAL_NOT_FOUND`; a failure releases the latch and remains retryable. An effect keyed on the goal's id resets this transient state and drops the edit form when the goal's identity changes, so neither a cleared marker nor a surviving draft can affect the replacement goal.

 可见性决定标签和操作：active 状态显示 "Ongoing Goal" 并提供暂停／编辑／清除；paused 状态显示 "Paused Goal"，把暂停换成一个恢复图标按钮；blocked 状态显示 "Blocked Goal"，并把 `blockedReason.message` 作为横条的 `title` 悬浮提示。创建目标的入口在 `/goal` 命令上，不在横条里。铅笔图标把横条切换为内联编辑表单，预填当前目标内容：Enter 或勾选按钮通过 `GoalBarActions.onEdit(objective)` 保存，Esc 取消，目标内容全为空白字符时保存按钮保持禁用。编辑成功后表单才会关闭；编辑失败时保留草稿，并在横条中显示错误。恢复和清除失败也显示在横条中。除此之外，清除直接调用 `onClear`，不做确认——清除会保留 durable 墓碑，没有不可恢复的损失。每次变更都会先取得一个同步的组件内 single-flight 锁，因为 React 的 pending 状态渲染无法关闭同一帧内的点击窗口。清除成功后还会立即抑制该 goal id，直到权威的 null 投影追上，因此已确认的墓碑不会留下陈旧的清除控件并再次提交 `GOAL_NOT_FOUND`；失败则释放锁，并且仍可重试。一个以目标 id 为键的 effect 会在目标身份变化时重置瞬态状态并丢弃编辑表单，因此无论已清除标记还是存留草稿，都不会影响替换目标。

 Tool rows are slots too — the standalone tool ring (`ToolViewRegistry`/`ctx.toolviews`/outlet) is retired. The chat entry declares the keyed `'conversation.chat.toolview'` hole (session scope; the key space is runtime-open); its render site dispatches per row via `entryKey: toolName` with `GenericToolCard` as the call-site `fallback`. The owner payload is the uniform `ToolRowOwnerProps` (`callId`/`toolName`/`block`/`openFile`) and `ToolRowProps` pre-composes it with the session standard kit. A registrant is a plain plugin: `ctx.slots.register({ name: 'conversation.chat.toolview', key: '', inject? }, Row)` with `inject: ['slots', 'conversation']` as the load-order seam (apply mounts ConversationService after the chat registration, so the service being present guarantees the slot is declared); the bash sample is the third-party-posture exemplar. Trajectory/waterfall toolview slots share this shape and land with their own render sites (RendersCheck rejects a declaration nobody renders).
 
-The todo surfaces are two registrations over that shape, both plain registrant plugins with `inject: ['slots', 'conversation']`. `TodoRow` takes the `'conversation.chat.toolview'` key `todo_write` and summarizes what the call attempted (`/ 已完成 · ` parsed from its args, falling back to the generic summary on malformed or wrongly-shaped model JSON, and keeping the generic dot for non-ok execution states so a cancelled call never reads as a completed update). `TodoDock` takes the `'conversation.input.dock'` list slot at `order: -1` — above the queue rows — and is the plan strip: it reads the host-computed `todos` projection via `useProjection` (standing plan: latest `todo/write` with no later `turn/start`) and renders `TodoPanel`, which takes the plain list, hides itself while the list is empty, and starts collapsed as a header of title plus `"/ tasks ·  in progress"` (status glyphs are the figma check / progress / dashed-pending set). The dock adapter owns the selection so the panel stays a pure function of its props; the standing list lives here rather than in the row so the row stays one line. Anything the input-zone composer chain hides (a `conversation.composer` takeover such as ui-question's) hides the whole dock, this strip included.

 `QueueDock` is the terminal input-dock entry at `order: 20`. It hides while empty, renders one pending row directly, and defaults two or more rows to a collapsed `" 条排队消息"` header whose button expands or collapses the complete list. The header exposes `aria-expanded` and `aria-controls`; the expanded list scrolls within a 180px height bound. An active edit or mutation keeps its rows visible, and emptying the queue restores the collapsed default for the next queue. Each visible row remains a single-line preview with its exact-occurrence edit and delete actions.

-Goal surface plugin, browser half: the `GoalBar` strip is the first standalone card in the `conversation.input.dock` composer-context stack (order 0, before Todo and Queue). The live goal arrives through `useProjection('goal')` — the host-computed whole value seeded by the history tail page and updated by `session/projection` frames — so the plugin owns no domain store, refresh chain, or event listener. The slot inject face carries only the four mutation verbs (edit / pause / resume / clear over the `goal.*` wire domain — an active goal offers the pause action, a paused one resume); each reads the CAS ref from the session's current projected value at call time and surfaces the settled RPC error inline. The strip single-flights mutations synchronously because React's pending render cannot fence same-frame clicks; after a successful clear it immediately suppresses that exact goal id while the authoritative null projection catches up. Goal creation stays on the `/goal` host command; loading, absent, completed, and successfully cleared goals render nothing.

Subject: [PATCH 362/557] feat(subagent): activation-based continuable
 subagents (source)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace the Task-backed continuation manager with one durable Session plus at
most one process-local Activation — a residency epoch for a reconstructed child
Agent, not a request, result, cancellation, or Task boundary. The manager owns
activation admission, authority, the live ownership graph, cold resume, and
child-first disposal; the Agent inbox is the only turn FIFO.

- startContinuable() is async and returns { childId, messageId } at inbox
  acceptance; followup() takes a SubagentAuthority and returns AgentMessageId.
- SubagentProvider.resume?(), SubagentProviderResumeRequest, SubagentRun.steer?(),
  SubagentProviderStartRequest and SubagentContinuation are deleted;
  prepareContinuable?() is the continuable-creation capability.
- Cold resume calls ctx.agents.resume() from the manager through a private
  activation-owner scope, never dispatching through a provider.
- Extract shared child composition, descriptor seeding, depth accounting, and
  one-shot run settlement so the manager and one-shot driver keep one home
  per fact.

Tests and docs follow in subsequent commits.

+# Agent Note: Continuable subagents
+
+Status: proposed
+
+English | [中文](2026-07-28-continuable-subagent-conversations.zh.md)
+
+This proposal would replace the Task-backed continuation manager from [Continuable background subagents](../../implemented/feature/2026-07-21-continuable-background-subagents.md). It retains the single `ctx.subagents` service from [Merge subagent control into the subagent service](../../implemented/simplification/2026-07-26-merge-subagent-control-service.md) and the intent-named `followup` operation from [Intent-named subagent continuation operations](../../implemented/simplification/2026-07-27-intent-named-subagent-continuation-operations.md).
+
+## Problem
+
+The continuation manager currently makes one Task, one provider execution, and one result boundary the same object lifetime. Task settlement disposes the child Agent, Task completion injects the completion notice, and later input reconstructs another Agent. This couples a generic background-work abstraction to conversation delivery even though a continuable subagent already has a Session and an Agent inbox.
+
+Giving queued parent requests to the continuation manager and user messages to the Agent creates two FIFOs with no single ordering authority. Giving both to Tasks instead duplicates the Agent loop's admission, cancellation, and quiescence machinery. `Agent.whenIdle()` cannot recover a per-request Task result because one running interval may drain multiple queued turns, and broad `Agent.cancel()` cannot remove one queued request exactly.
+
+The runtime lifetime is also wider than one turn. A subagent can finish its own turn while a child it created is still running. Disposing the parent runtime at that point removes the Agent that still owns descendant teardown. Keeping every historical subagent resident instead would make memory use unbounded.
+
+Users and parent Agents also need to send later work to the same live child without changing its current turn. Queueing every continuation message as a follow-up preserves one ordering rule for both senders.
+
+## Proposal
+
+A continuable subagent has one durable Session and at most one process-local Activation:
+
+```text
+persisted Session
+  -> optional live Activation
+       -> one retained AgentHandle
+       -> Agent inbox as the only turn FIFO
+       -> zero or more owned child Activations
+```
+
+An Activation is one residency epoch for a reconstructed child Agent. It may execute multiple FIFO turns and remain resident while waiting for descendants. It is not a request, result, cancellation, or Task boundary.
+
+The continuation manager owns activation admission, authority checks, the live ownership graph, cold resume, and child-first disposal. The Agent loop owns all turn ordering and execution. The proposal creates no Task for a continuable subagent, no Activation FIFO, and no queued Activation state.
+
+### Materialization and public operations
+
+The named subagent provider participates only in preparing the initial creation spec, where `spawn` and `fork` differ. Its optional `prepareContinuable(request): Promise` method is the continuable-creation capability. The returned spec contains only detached provider-specific creation inputs such as the optional parent-history seed; it contains no Agent, `AgentHandle`, prompt delivery, result, disposal, or resume operation. The manager reserves the child identity, resolves the durable descriptor and common Agent setup, calls `ctx.agents.create()` through a private activation-owner scope, installs the returned `AgentHandle` into the Activation, establishes any continuable-parent ownership, and then calls `Agent.followup(initialPrompt)`. Inbox acceptance yields an `AgentMessageId`; at that boundary `ctx.subagents.startContinuable()` returns `{ childId, messageId }` without waiting for the turn to start or for the message to enter the Session log.
+
+Any failure before inbox acceptance rejects without returning either id. Agent creation provides rollback before handle transfer; after transfer, the manager disposes the created handle, removes the Activation, and rolls back any parent `ownedChildren` membership before rejecting.
+
+`backgroundMode: 'one-shot' | 'continuable'` remains deployment policy. Configured continuable mode requires `prepareContinuable`; method presence replaces `SubagentProvider.resume?()` as the capability check, while a capable provider may still run one-shot work.
+
+Cold resume does not dispatch through a subagent provider. The continuation manager folds the generic in-process descriptor, calls `ctx.agents.resume()` through the same activation-owner scope, installs the returned `AgentHandle`, and submits the waiting `next-turn`. `SubagentProvider.resume?()` and `SubagentProviderResumeRequest` are absent, and the initial provider name is not a recovery capability; remote providers require a separate design.
+
+`SubagentProvider.start()` and `SubagentRun` remain exclusively on the unchanged one-shot path. A continuable Activation directly owns its `AgentHandle` and never creates, wraps, or retains a `SubagentRun`; `SubagentRun.steer?()` is therefore absent.
+
+`ctx.subagents.followup(authority, childId, content, { source, signal })` remains the sole continuation-message operation. `authority` is either `{ kind: 'parent', agent }` or `{ kind: 'user' }`; the parent variant is admitted only from an exact live Agent tool context, while only a trusted host adapter can supply user authority. `source` remains durable provenance and grants no authority. The model-facing `send_message` tool keeps only its stable `subagent_id` and `message` fields and always submits a follow-up turn. Both start and follow-up return the accepted `AgentMessageId`, and neither reports how the manager materialized the Activation.
+
+For start and follow-up, the caller signal owns lookup, materialization, and admission only until inbox acceptance. After the operation returns its `AgentMessageId`, the manager owns the Activation independently; later caller cancellation does not cancel the accepted turn or dispose the child.
+
+### Durable Session and live Activation
+
+The Session owns the stable child identity, transcript, direct-parent lineage, delegation depth, and versioned continuation descriptor. `SessionHeader.parentSession` is durable provenance and an authorization input; it is not a live routing capability and does not imply that the historical parent is resident.
+
+An idle historical Session has no `AgentHandle`. The first authorized `next-turn` delivery resumes an Activation from the persisted Session and submits the message to its inbox. A user-authorized cold resume does not load the historical parent Agent. A parent-originated resume uses the exact live parent Agent for authorization and, when that parent has an Activation, ownership; it never uses the parent for reconstruction.
+
+The Activation directly owns the published `AgentHandle` until it settles, while the manager's private activation-owner scope is its structural Cordis owner. The continuable path creates no intermediate result-bearing execution wrapper, including `SubagentRun`; one-shot delegation remains unchanged and outside this lifecycle. Remote providers are outside the MVP and require a separate Activation ownership contract when introduced. Historical Sessions consume no runtime memory after their Activation is disposed.
+
+### Activation lifecycle
+
+The public lifecycle has three states and no `queued` state:
+
+```text
+running
+  | Agent quiescent with live children
+  v
+waiting
+  | next-turn
+  +--------------------------> running
+
+running or waiting
+  | Agent quiescent and no live children
+  v
+settled
+  | AgentHandle.dispose completes
+  v
+no Activation
+```
+
+`running` means the Agent has an active admission or turn, or its inbox contains waking work. `waiting` means the Agent is quiescent but the Activation still owns at least one child Activation that has not completed disposal. `settled` means the Agent is quiescent and every owned child is disposed; the manager then disposes the `AgentHandle` and removes the Activation.
+
+The manager derives these states from Agent quiescence and the owned-child set rather than maintaining a second execution state machine. A `next-turn` delivered while `running` joins the Agent inbox. A `next-turn` delivered while `waiting` wakes the same Agent and returns the Activation to `running`. Delivery after disposal cold-resumes a new Activation.
+
+The manager linearizes delivery, child release, and disposal for each durable child. If a delivery races with final disposal, exactly one side wins the admission cutoff: delivery either enters the still-live Agent inbox, or waits for disposal and cold-resumes a new Activation. No caller can send to a handle after its disposal transaction begins.
+
+### One inbox and follow-up delivery
+
+The Agent inbox is the only queue. Every continuation message uses `Agent.followup()` and becomes one FIFO turn; neither the continuation manager nor the host maintains another message queue. Every accepted waking item keeps the current Activation live until `Agent.whenIdle()` observes the complete waking suffix.
+
+Routing depends only on Activation residency:
+
+| Activation state | Sender | `followup` |
+|---|---|---|
+| `running` | parent or user | enqueue in the same Activation |
+| `waiting` | parent or user | wake the same Activation |
+| no Activation | parent or user | cold-resume a new Activation |
+
+The continuation layer defines no separate delivery-route result. Successful `ctx.subagents.followup()` and `send_message` delivery returns the accepted `AgentMessageId`, while delivery failure throws. Existing `agent/inbox/enqueue`, `agent/inbox/dequeue`, and `agent/inbox/discard` events remain the message-lifecycle observations; adapters may render a generic acceptance but do not expose `started`, `queued`, `resumed`, or another subagent-specific route vocabulary.
+
+### Child ownership
+
+Every Activation owns its `AgentHandle` and an `ownedChildren: Set`. Because one Session has at most one live Activation, the child Session id identifies the live child without another runtime-incarnation reference. `SessionHeader.parentSession` records the durable direct-parent identity, while membership in `ownedChildren` records the process-local ownership relationship.
+
+When the authenticated parent is itself a continuation-managed Activation, starting a child or submitting parent-originated work adds the child Session id to that parent's `ownedChildren` before the child can run or the message can enter its inbox. That parent cannot settle or dispose while this set is non-empty. A top-level or other non-continuation Agent has no Activation and does not join this waiting graph.
+
+Child release occurs only after the child Agent is quiescent, every child of that child is disposed, the final durability checkpoint settles, and the child's `AgentHandle` completes disposal. The manager calls `ctx.sessions.flush(child.session)`: `true` confirms durability, while `false` or rejection is normalized to `DURABILITY_FAILED`. A failed checkpoint is reported but does not prevent handle disposal or ownership release, because retaining a failed child would permanently pin its ancestors in `waiting`. If the child is owned, the manager then resolves the live parent through `SessionHeader.parentSession` and removes the child Session id from its `ownedChildren`; a user-resumed child with no live owner has nothing to release. Manager teardown uses the same child-first order.
+
+A user cold-resume creates an Activation without adding it to the historical parent's `ownedChildren`. If the direct parent later submits work to that live Activation and is itself continuation-managed, admission establishes ownership before enqueueing the message; a non-continuation parent remains outside the waiting graph.
+
+The MVP retains ownership until the child Activation is disposed. A later refinement may release a request-scoped lease earlier, but it would require an exact turn-completion correlation that this Task-free proposal deliberately does not add.
+
+Top-level teardown is host-owned rather than represented as another Activation. The host first asks the manager to enter draining synchronously, which rejects new creation, resume, and delivery admission, then disposes every live Activation forest in child-first order and awaits all `AgentHandle.dispose()` calls. Only after that drain settles may the host dispose top-level Agents and the manager scope. Manager unload uses the same drain and includes user-resumed Activations without live owners.
+
+The activation-owner scope exists because ordinary Cordis owner effects unwind in reverse registration order, which cannot express the dynamic child graph. Manager initialization registers the private scope's structural disposer first and its drain disposer afterward, so reverse unwind invokes the drain before releasing that scope; merely registering a cleanup effect on the same scope as later Agent handles would allow structural handle disposal to bypass child-first ordering. The manager snapshots the live roots after closing admission, stops its outward lifecycle notifications before cancellation, and retains its internal ownership bookkeeping until every handle settles. Each Activation has one memoized disposal promise so host shutdown, manager unload, child release, and normal settlement can converge without double release. Sibling branches drain independently; one disposal failure is recorded but does not prevent the manager from attempting the remaining handles, and the aggregate drain reports failure after all branches settle. Durable child Sessions survive this process-local teardown.
+
+### Deferred report delivery
+
+The MVP exposes no `report` tool and provides no child-to-parent content delivery or automatic parent wakeup. The durable child Session remains the source of the child's detailed output.
+
+A later proposal may add an ordinary model-facing `report(output)` tool that can be called zero or multiple times in one turn. Its delivery policy may distinguish quiet parent injection from waking the parent; recipient selection, acknowledgement, durability, and retry semantics are deferred with that tool. Adding report delivery does not require another Activation state or execution queue.
+
+### Deferred steering
+
+The MVP exposes no subagent steering operation. Parent and user continuation messages always open later FIFO turns, so the continuation layer stores no current-turn controller and adds no controller-aware Agent admission seam.
+
+A later host UI may expose separate **Steer** and **Follow up** actions. User steering would be strict and live-only: it may call the existing Agent steering path only while the Activation accepts a next step, must reject otherwise, and must never fall back to queueing or cold resume. Exposing parent steering to a model-facing tool remains a separate design because distinct tool names express intent but do not establish whether the parent may modify a user-controlled turn.
+
+### Authority and provenance
+
+Authority is supplied by a trusted host interaction or an exact live Agent tool context. `MessageSource` and `senderSessionId` are durable provenance after admission, not caller-controlled authority.
+
+The MVP authorizes the host user and the durable child's direct parent. Parent authorization checks `SessionHeader.parentSession` against the authenticated parent Agent before registering the child in that parent's `ownedChildren`. Other Agents, ancestors, teams, and workflows remain rejected until an explicit authority protocol exists.
+
+User authority may cold-resume a child without its parent. Parent-originated delivery requires the parent to be live when admitted and keeps it live through the ownership relationship.
+
+### Durability, disposal, and recovery
+
+Without Tasks there is no `task_output`, `task_kill`, Task status, per-message result promise, or public subagent cancellation operation. The caller signal can abort start or follow-up only before inbox acceptance. After acceptance, neither parent nor user can cancel the message, turn, or Activation through `ctx.subagents`; `Agent.cancel()` remains a lower-level Agent capability that this MVP does not expose through the subagent service.
+
+Host and manager teardown remains the lifecycle-wide stop path. It closes admission, disposes every live Activation forest child-first, and preserves the durable Sessions.
+
+Each turn requests the Session durability checkpoint, and final Activation settlement requires the manager to inspect `ctx.sessions.flush()` rather than ignore its boolean result. `true` confirms that at least one durability listener participated and every listener settled successfully. `false` or rejection reports `DURABILITY_FAILED`; normal background settlement logs the lifecycle failure, while an explicit host or manager drain includes it in the aggregate rejection after all branches settle. Either way, the manager still disposes the handle and releases ownership, and the persisted child state may be missing or stale on a later resume.
+
+Only messages written to the child Session log are reconstructable with their admitted provenance; inbox acceptance alone provides no restart guarantee.
+
+Session and descriptor persistence survive restart. Activation state, Agent inbox contents, and the ownership graph are process-local. A process crash may lose an accepted initial prompt or follow-up that remained in the inbox without reaching the Session log. The Session and descriptor may survive so a later authorized message can cold-resume the child, but the lost message is not replayed automatically. Recovering accepted unfinished or unlogged messages requires a durable inbox protocol and is not implied here.
+
+### Scope
+
+The MVP covers continuable in-process children and leaves one-shot delegation unchanged. Remote providers require a separate Activation handle with equivalent authenticated control and child-first quiescence contracts before they can support the same behavior.
+
+The MVP adds no subagent steering operation, report tool, child-to-parent content delivery, automatic parent wakeup, durable mailbox, cross-process lease, automatic replay of interrupted inbox work, team authority, workflow authority, public subagent cancellation operation, new live-Activation or descendant limit, or runtime cache. Existing delegation-depth policy remains unchanged.
+
+## Alternatives considered
+
+**Keep Task-backed Activations.** Tasks provide generic status, result collection, and cancellation, but using them for conversation delivery creates a second queue and duplicates turn ownership. The proposal gives up those generic Task controls so the Agent inbox remains the only execution order.
+
+**Create one Activation per `next-turn`.** This restores independent result and cancellation boundaries, but it requires a manager FIFO beside the Agent inbox and makes a retained Agent cross artificial Activation boundaries. One Activation per residency epoch is smaller and follows the `AgentHandle` lifetime directly.
+
+**Dispose the Agent while waiting.** Reconstructing a parent while its child still belongs to the previous process-local ownership graph would require a durable ownership and teardown protocol. Retaining the `AgentHandle` only for the unfinished graph preserves child-first teardown without keeping settled history resident.
+
+**Let the provider create, resume, or deliver through an Agent handle.** Initial providers own only `prepareContinuable()` and its detached creation-spec distinction: whether a child begins fresh or with a parent prefix. The manager must call `ctx.agents.create()` through its private activation-owner scope so that scope is a structural owner of every handle. A persisted in-process Session already contains the initial prefix and generic reconstruction descriptor, while delivery belongs to the Agent inbox. Giving providers any later handle, `SubagentRun`, or message ownership would preserve a seam with no MVP behavior to own and would complicate user cold resume with an unnecessary live-parent input.
+
+**Add report delivery to the MVP.** A repeatable model-facing tool is compatible with this lifecycle, but quiet versus waking delivery, recipient selection, acknowledgement, durability, and retry behavior are independent product choices. Deferring the tool keeps the first version focused on conversation admission and residency without constraining that later policy.
+
+**Treat `SessionHeader.parentSession` as live ownership.** Durable lineage does not prove that the historical parent currently owns the child. Membership in the live parent's `ownedChildren` records the process-local relationship without changing durable provenance.
+
+**Retain the exact parent Agent in a separate link.** The parent Activation already owns its `AgentHandle`, and `ownedChildren` prevents that Activation from disposing while the child remains live. Resolving the parent by Session id is therefore sufficient and avoids a redundant runtime reference.
+
+**Maintain a separate queue for parent messages.** A second FIFO creates ambiguous ordering against user messages already accepted by the Agent. A single Agent inbox gives both origins one observable order.
+
+**Expose subagent steering in the MVP.** User steering can be a strict live-only host action, but parent steering needs current-turn controller state to protect a user-controlled turn. Queueing every first-version continuation avoids that state and its admission race. A later UI can add a distinct user-only action without changing follow-up ordering.
+
+**Return a subagent-specific delivery route.** Labels such as `started`, `queued`, and `resumed` duplicate Activation and inbox state without giving the caller an independent result. Reusing `AgentMessageId` and the existing inbox events keeps delivery correlation on the Agent contract that owns it.
+
+**Use a child reference count.** A count cannot identify which child still owns teardown work and permits duplicate decrement errors. An identity set retains cancellation and disposal obligations explicitly.
+
+## Acceptance criteria
+
+- A continuable child has at most one live Activation and one Agent inbox; the continuation manager has no Activation FIFO or queued Activation state.
+- `SubagentProvider.prepareContinuable?()` returns only a detached `ContinuableCreateSpec`; configured continuable mode requires that capability, while `backgroundMode` remains an independent policy choice.
+- The manager calls `ctx.agents.create()` through its private activation-owner scope, installs the returned `AgentHandle` and parent ownership, calls `Agent.followup(initialPrompt)`, and returns `{ childId, messageId }` when inbox acceptance yields the `AgentMessageId`, without waiting for turn start or a Session-log write.
+- Every failure before initial-prompt inbox acceptance rejects without ids and rolls back any created handle, Activation, and parent `ownedChildren` membership.
+- Cold resume calls `ctx.agents.resume()` from the continuation manager and never dispatches through the initial subagent provider; `SubagentProvider.resume?()` and `SubagentProviderResumeRequest` are absent.
+- A continuable Activation directly owns `AgentHandle` and never creates, wraps, or retains `SubagentRun`; `SubagentProvider.start()` and `SubagentRun` remain one-shot-only, without `SubagentRun.steer?()`.
+- A user can cold-resume a persisted child without loading its historical parent.
+- `followup()` accepts only trusted parent or user authority; durable message provenance cannot authorize delivery.
+- Parent and user continuation messages always use `Agent.followup()` and share its inbox FIFO, including when one origin queues behind the other or the child already has an open turn.
+- `ctx.subagents.followup()` and its `send_message` adapter return only the accepted `AgentMessageId`; the continuation layer accepts no delivery target and defines no subagent-specific route result.
+- The MVP exposes no public subagent cancellation operation; caller signals stop start and follow-up only before inbox acceptance, while host and manager teardown retains child-first global cleanup.
+- The MVP exposes no subagent steering operation or current-turn controller state.
+- An idle Agent with live owned children yields a `waiting` Activation whose `AgentHandle` remains retained.
+- A `next-turn` delivered to `waiting` wakes the same Activation; delivery after completed disposal cold-resumes a new Activation.
+- Every continuation-managed parent Activation disposes only after all directly owned child Activations complete `AgentHandle` disposal; top-level Agents do not join the waiting graph.
+- Final Activation settlement treats only `ctx.sessions.flush(child.session) === true` as durability confirmation; `false` and rejection report `DURABILITY_FAILED`, still dispose the child handle, and still release parent ownership so durability failure cannot leak a `waiting` Activation.
+- Host and manager teardown synchronously enter draining, reject new materialization and delivery, stop manager-owned outward notifications, dispose every snapshotted live Activation forest child-first, await every branch despite individual failures, and only then dispose top-level Agents and the manager scope; a private activation-owner scope preserves this order against Cordis effect unwinding, and one memoized disposal promise per Activation makes concurrent normal settlement idempotent.
+- The MVP exposes no `report` tool, child-to-parent content delivery, or automatic parent wakeup.
+- Session logs reconstruct only messages that were actually written, with their admitted provenance; inbox-accepted but unlogged messages have no restart guarantee.
+- No continuable-subagent path creates or depends on a Task, `TaskId`, Task completion notice, Task cancellation, or intermediate result-bearing execution wrapper.
+- Unit coverage pins the `startContinuable()` inbox-acceptance return boundary, complete rollback for each pre-acceptance failure, caller-signal ownership on both sides of acceptance, and the absence of automatic replay for accepted-but-unlogged messages.
+- Unit coverage pins the residency-only routing table, single-inbox ordering, `AgentMessageId` correlation through inbox events, follow-up during an open turn, waiting wakeup, cold resume, ownership registration and release, child-first disposal, send-versus-dispose races, both `false` and rejection from the final durability checkpoint without ownership leaks, and the absence of public subagent cancellation, steering, and report tools.
+- A keyless assembled-app snapshot covers parent delegation, mixed parent/user follow-up queueing, the absence of subagent steering, report delivery, and automatic parent wakeup, retained waiting `AgentHandle`, and child-first disposal.
+
+## Risks
+
+Removing Tasks gives up generic background-work inspection, result collection, and exact Task cancellation. If those product features become requirements, they need a request ticket or inbox capability that does not reintroduce a second execution queue.
+
+Retaining an Activation while descendants run consumes Agent resources proportional to the unfinished ownership graph. The existing delegation-depth policy still bounds nesting, but the MVP adds no live-Activation or total-descendant limit; settled historical Sessions retain no `AgentHandle`.
+
+The process-local inbox and ownership graph do not coordinate two harness processes. Deployments allowing concurrent access to one persistence store still require a durable lease and mailbox protocol.
+
+Without report delivery, completing a child turn neither sends its content to nor wakes the historical parent. The output remains in the durable child Session until a caller inspects that transcript or submits another authorized turn. A later report tool may add quiet or waking delivery without changing the Activation lifecycle.
+
+Queueing every continuation message means a parent cannot correct an in-progress child turn immediately; the correction runs as the next turn. A later user-only UI steering action may reduce that latency without introducing parent-versus-user controller policy into the MVP.
+
+A failed final durability checkpoint allows the runtime ownership graph to drain but leaves the persisted child state missing or stale. The failure is observable as `DURABILITY_FAILED`; retry and repair require a separate recovery design.

+# Agent Note（agent 决策记录）：可继续的 subagent
+
+Status: proposed
+
+[English](2026-07-28-continuable-subagent-conversations.md) | 中文
+
+本提案将取代[可继续的后台 subagent](../../implemented/feature/2026-07-21-continuable-background-subagents.md)中由 Task 支撑的继续执行管理器。提案保留[将 subagent 控制合并到 subagent 服务](../../implemented/simplification/2026-07-26-merge-subagent-control-service.md)确立的单一 `ctx.subagents` 服务，以及[以意图命名的 subagent 继续执行操作](../../implemented/simplification/2026-07-27-intent-named-subagent-continuation-operations.md)确立的 `followup` 操作。
+
+## 问题
+
+继续执行管理器目前让一个 Task、一次提供方执行和一个结果边界共享同一生命周期。Task 结算会 dispose（资源释放）child Agent，Task 完成会注入完成通知，后续输入则重建另一个 Agent。这使通用后台工作抽象与会话投递耦合，而可继续 subagent 已经具备会话和 Agent inbox。
+
+如果继续执行管理器为 parent 请求排队，而 Agent 接收用户消息，系统就会出现两个 FIFO，且没有唯一的顺序权威。如果两种消息都交给 Task，系统又会重复 agent loop（智能体循环）已有的准入、取消和完全停稳机制。`Agent.whenIdle()` 无法恢复单项请求的 Task 结果，因为一个运行区间可能清空多个排队轮次；宽泛的 `Agent.cancel()` 也不能精确移除一项排队请求。
+
+运行时生命周期也比单个轮次更长。subagent 可能已经结束自身轮次，但它创建的 child 仍在运行。此时 dispose parent 运行时，会移除仍负责后代拆卸的 Agent。反之，如果让所有历史 subagent 始终驻留，内存使用就会失去上界。
+
+用户和 parent Agent 还需要在不改变当前轮次的前提下，向同一个在线 child 发送后续工作。将每条继续执行消息作为 follow-up 排队，可以让两类发送方遵循同一项排序规则。
+
+## 提案
+
+一个可继续 subagent 拥有一个持久化会话，并且至多拥有一个进程内激活：
+
+```text
+persisted Session
+  -> optional live Activation
+       -> one retained AgentHandle
+       -> Agent inbox as the only turn FIFO
+       -> zero or more owned child Activations
+```
+
+激活是重建 child Agent 的一次驻留周期。它可以执行多个 FIFO 轮次，并在等待后代时保持驻留。它不是请求、结果、取消或 Task 边界。
+
+继续执行管理器负责激活准入、权限检查、在线所有权图、冷恢复和 child-first dispose。Agent loop 负责全部轮次排序与执行。本提案不会为可继续 subagent 创建 Task、激活 FIFO 或 queued 激活状态。
+
+### 物化与公开操作
+
+具名 subagent 提供方只参与准备初始创建规格，此时 `spawn` 与 `fork` 有所区别。其可选的 `prepareContinuable(request): Promise` 方法就是可继续创建能力。返回的规格只包含与 Agent 实例分离且由提供方决定的创建输入，例如可选的 parent 历史种子；它不包含 Agent、`AgentHandle`、提示词投递、结果、dispose 或恢复操作。管理器会预留 child 身份，解析持久化描述符和通用 Agent 配置，通过私有 activation-owner 作用域调用 `ctx.agents.create()`，将返回的 `AgentHandle` 安装到激活中，建立适用的可继续 parent 所有权，然后调用 `Agent.followup(initialPrompt)`。inbox 接受消息后会产生一个 `AgentMessageId`；`ctx.subagents.startContinuable()` 在此边界返回 `{ childId, messageId }`，不等待轮次开始，也不等待消息写入会话日志。
+
+inbox 接受消息前发生任何失败，操作都会在不返回任何 id 的情况下被拒绝。Agent 创建流程负责 handle 移交前的回滚；移交后，管理器会先 dispose 已创建的 handle、移除激活并回滚 parent `ownedChildren` 中的任何成员关系，再拒绝操作。
+
+`backgroundMode: 'one-shot' | 'continuable'` 仍是部署策略。配置为 continuable 时要求存在 `prepareContinuable`；该方法是否存在会取代 `SubagentProvider.resume?()` 成为能力检查，而具备该能力的提供方仍可运行 one-shot 工作。
+
+冷恢复不会通过 subagent 提供方分发。继续执行管理器会归并通用的进程内描述符，通过同一个 activation-owner 作用域调用 `ctx.agents.resume()`，安装返回的 `AgentHandle`，并提交等待中的 `next-turn`。`SubagentProvider.resume?()` 和 `SubagentProviderResumeRequest` 均不存在，初始提供方名称也不是恢复能力；远程提供方需要单独设计。
+
+`SubagentProvider.start()` 和 `SubagentRun` 只保留在不变的 one-shot 路径上。可继续激活直接持有自身的 `AgentHandle`，绝不创建、包装或保留 `SubagentRun`；因此，`SubagentRun.steer?()` 不存在。
+
+`ctx.subagents.followup(authority, childId, content, { source, signal })` 仍是唯一的继续执行消息操作。`authority` 可以是 `{ kind: 'parent', agent }` 或 `{ kind: 'user' }`；parent 变体仅能从确切的在线 Agent 工具上下文通过准入，只有可信宿主适配器才能提供用户权限。`source` 仍是持久化来源信息，不赋予任何权限。面向模型的 `send_message` 工具只保留稳定的 `subagent_id` 和 `message` 字段，并始终提交一个 follow-up 轮次。start 和 follow-up 都返回已接受的 `AgentMessageId`，两者都不报告管理器如何物化激活。
+
+对于 start 和 follow-up，调用方 signal 只在 inbox 接受消息前持有查找、物化和准入。操作返回 `AgentMessageId` 后，管理器会独立持有该激活；调用方之后的取消不会取消已接受的轮次，也不会 dispose child。
+
+### 持久化会话与在线激活
+
+会话持有稳定的 child 身份、transcript（文本记录）、直接 parent 谱系、委派深度和带版本的继续执行描述符。`SessionHeader.parentSession` 是持久化来源信息和鉴权输入；它不是在线路由能力，也不表示历史 parent 仍然驻留。
+
+空闲的历史会话没有 `AgentHandle`。第一条通过鉴权的 `next-turn` 投递会根据持久化会话恢复激活，并将消息提交到其 inbox。经用户授权的冷恢复不会加载历史 parent Agent。parent 发起的恢复使用经过身份认证的确切在线 parent Agent 执行鉴权；当该 parent 有激活时，还使用它建立所有权，但绝不使用 parent 执行重建。
+
+激活作为消费方会直接持有已发布的 `AgentHandle` 直至结算，而管理器的私有 activation-owner 作用域则是其 Cordis 结构化所有者。可继续 subagent 路径不创建任何中间的带结果执行包装层，包括 `SubagentRun`；一次性委派保持不变，且不属于该生命周期。远程提供方不在 MVP 范围内，引入时需要单独的激活所有权契约。激活 dispose 后，历史会话不消耗运行时内存。
+
+### 激活生命周期
+
+公开生命周期只有 3 个状态，没有 `queued` 状态：
+
+```text
+running
+  | Agent quiescent with live children
+  v
+waiting
+  | next-turn
+  +--------------------------> running
+
+running or waiting
+  | Agent quiescent and no live children
+  v
+settled
+  | AgentHandle.dispose completes
+  v
+no Activation
+```
+
+`running` 表示 Agent 正在执行准入或轮次，或者 inbox 中存在会唤醒 Agent 的工作。`waiting` 表示 Agent 已经完全停稳，但激活仍持有至少一个尚未完成 dispose 的 child 激活。`settled` 表示 Agent 已经完全停稳且所有持有的 child 都已 dispose；随后管理器会 dispose `AgentHandle` 并移除激活。
+
+管理器根据 Agent 是否完全停稳以及所持 child 集合派生这些状态，而不是维护第二套执行状态机。在 `running` 时投递的 `next-turn` 会进入 Agent inbox。在 `waiting` 时投递的 `next-turn` 会唤醒同一个 Agent，并使激活回到 `running`。在 dispose 完成后投递消息则会冷恢复新激活。
+
+管理器会针对每个持久化 child，将投递、child 释放和 dispose 线性化。如果投递与最终 dispose 发生竞争，只有一方能越过准入截止点：投递要么进入仍在线的 Agent inbox，要么等待 dispose 完成后冷恢复新激活。任何调用方都不能向已经开始 dispose 事务的 handle 发送消息。
+
+### 一个 inbox 与 follow-up 投递
+
+Agent inbox 是唯一队列。每条继续执行消息都使用 `Agent.followup()`，并成为一个 FIFO 轮次；继续执行管理器和宿主都不维护另一条消息队列。每个已接受且会唤醒 Agent 的条目都会让当前激活保持在线，直至 `Agent.whenIdle()` 观察到完整的唤醒工作后缀已经结束。
+
+路由只取决于激活的驻留状态：
+
+| 激活状态 | 发送方 | `followup` |
+|---|---|---|
+| `running` | parent 或 user | 在同一激活中排队 |
+| `waiting` | parent 或 user | 唤醒同一激活 |
+| 无激活 | parent 或 user | 冷恢复新激活 |
+
+继续执行层不定义单独的投递路由结果。成功投递 `ctx.subagents.followup()` 或 `send_message` 时会返回已接受的 `AgentMessageId`，投递失败则会抛出异常。现有的 `agent/inbox/enqueue`、`agent/inbox/dequeue` 和 `agent/inbox/discard` 事件仍用于观测消息生命周期；适配器可以呈现通用的接受确认，但不暴露 `started`、`queued`、`resumed` 或其他 subagent 专属路由词汇。
+
+### child 所有权
+
+每次激活都持有自身的 `AgentHandle` 和一个 `ownedChildren: Set`。由于一个会话至多有一次在线激活，child 会话 id 足以标识在线 child，无需另一个运行时 incarnation 引用。`SessionHeader.parentSession` 记录持久化的直接 parent 身份，`ownedChildren` 中的成员关系则记录进程内所有权关系。
+
+当经过身份认证的 parent 自身是由继续执行管理器管理的激活时，启动 child 或提交由 parent 发起的工作，会在 child 可以运行或消息可以进入其 inbox 前，将 child 会话 id 加入该 parent 的 `ownedChildren`。该集合非空时，这个 parent 不能结算或 dispose。顶层 Agent 或其他非继续执行 Agent 没有激活，也不会加入该等待图。
+
+只有在 child Agent 完全停稳、该 child 持有的每个 child 都已 dispose、最终持久性检查点结算且 child 的 `AgentHandle` 完成 dispose 后，系统才释放 child。管理器会调用 `ctx.sessions.flush(child.session)`：只有 `true` 确认持久性，`false` 或 rejection 则统一报告为 `DURABILITY_FAILED`。检查点失败会被报告，但不会阻止 handle dispose 或释放所有权，因为保留失败的 child 会让其祖先永久固定在 `waiting`。如果 child 归 parent 所有，管理器随后会通过 `SessionHeader.parentSession` 解析在线 parent，并从其 `ownedChildren` 中移除 child 会话 id；由用户恢复且没有在线 owner 的 child 则没有需要释放的所有权记录。管理器拆卸使用相同的 child-first 顺序。
+
+用户冷恢复会创建一次激活，但不会将其加入历史 parent 的 `ownedChildren`。如果直接 parent 随后向这个在线激活提交工作，且该 parent 自身由继续执行管理器管理，准入过程会在消息入队前建立所有权；非继续执行 parent 仍位于等待图之外。
+
+MVP 会一直保留所有权，直至 child 激活完成 dispose。后续改进可以更早释放限定到请求的 lease，但这需要精确关联轮次完成，而本 Task-free 提案特意不增加该机制。
+
+顶层拆卸由宿主负责，而不表示为另一次激活。宿主首先要求管理器同步进入 draining，拒绝新的创建、恢复和投递准入；然后按 child-first 顺序 dispose 整个在线激活森林，并等待全部 `AgentHandle.dispose()` 调用。只有该 drain 结算后，宿主才能 dispose 顶层 Agent 和管理器作用域。管理器卸载使用相同的 drain，并涵盖由用户恢复且没有在线 owner 的激活。
+
+activation-owner 作用域之所以存在，是因为普通 Cordis owner effect 按注册逆序撤销，无法表达动态 child 图。管理器初始化时先注册私有作用域的结构化 disposer，再注册自身的 drain disposer，使逆序撤销先执行 drain、再释放该作用域；如果只在与后续 Agent handle 相同的作用域上注册 cleanup effect，结构化 handle dispose 就可能绕过 child-first 顺序。管理器在关闭准入后对在线根节点创建快照，在取消前停止自身的对外生命周期通知，并保留内部所有权簿记，直至每个 handle 都结算。每次激活有一个记忆化的 dispose promise，使宿主关闭、管理器卸载、child 释放和正常结算能够汇合，而不会重复释放。同级分支独立 drain；系统会记录单次 dispose 失败，但仍会尝试其余 handle，聚合 drain 则在所有分支结算后报告失败。这次进程内拆卸不会销毁持久化 child 会话。
+
+### 延后的报告投递
+
+MVP 不暴露 `report` 工具，也不提供从 child 到 parent 的内容投递或自动唤醒 parent。持久化 child 会话仍是 child 详细输出的来源。
+
+后续提案可以增加一个普通的面向模型 `report(output)` 工具；模型在一个轮次中可以调用它零次或多次。其投递策略可以区分静默注入 parent 与唤醒 parent；接收方选择、确认、持久性和重试语义均与该工具一并延后决定。增加报告投递无需引入另一个激活状态或执行队列。
+
+### 延后的 steering（中途引导）
+
+MVP 不暴露 subagent steering 操作。parent 和用户的继续执行消息始终开启后续 FIFO 轮次，因此继续执行层不存储当前轮次控制方，也不新增能够感知控制方的 Agent 准入 seam。
+
+后续宿主 UI 可以分别暴露 **Steer** 和 **Follow up** 操作。用户 steering 必须严格且仅限在线使用：只有当激活接受下一步骤时，它才能调用现有的 Agent steering 路径；其他情况必须拒绝，而且绝不能转为排队或冷恢复。是否通过面向模型的工具暴露 parent steering 仍需单独设计，因为不同的工具名称可以表达意图，却不能确定 parent 是否可以修改由用户控制的轮次。
+
+### 权限与来源
+
+权限来自可信宿主交互或确切的在线 Agent 工具上下文。`MessageSource` 和 `senderSessionId` 是准入后的持久化来源信息，不是由调用方控制的权限。
+
+MVP 授权宿主用户和持久化 child 的直接 parent。系统会根据经过身份认证的 parent Agent 检查 `SessionHeader.parentSession`，然后才将 child 注册到该 parent 的 `ownedChildren`。其他 Agent、祖先、团队和工作流仍被拒绝，直至系统具备显式权限协议。
+
+用户权限可以在 parent 不在线时冷恢复 child。由 parent 发起的投递要求 parent 在准入时在线，并通过所有权关系使其继续在线。
+
+### 持久性、dispose 与恢复
+
+没有 Task 后，系统不再提供 `task_output`、`task_kill`、Task 状态、逐消息结果 promise 或公开 subagent 取消操作。调用方 signal 只能在 inbox 接受消息前中止 start 或 follow-up。消息被接受后，parent 和用户都不能通过 `ctx.subagents` 取消该消息、轮次或激活；`Agent.cancel()` 仍是底层 Agent 能力，但本 MVP 不通过 subagent 服务暴露它。
+
+宿主和管理器拆卸仍是覆盖整个生命周期的停止路径。它会关闭准入，按 child-first 顺序 dispose 每个在线激活森林，并保留持久化会话。
+
+每个轮次都会请求执行会话持久性检查点，激活最终结算时，管理器必须检查 `ctx.sessions.flush()`，而不能忽略其布尔结果。`true` 确认至少有一个持久性 listener 参与，且所有 listener 都成功结算。`false` 或 rejection 会报告 `DURABILITY_FAILED`；普通后台结算会记录该生命周期失败，显式的宿主或管理器 drain 则会在所有分支结算后，将其纳入聚合 rejection。无论结果如何，管理器仍会 dispose handle 并释放所有权，后续恢复时持久化 child 状态可能缺失或陈旧。
+
+只有实际写入 child 会话日志的消息，才能根据其准入来源重建；仅被 inbox 接受并不提供重启保证。
+
+会话和描述符的持久化状态可在重启后保留。激活状态、Agent inbox 内容和所有权图都是进程内状态。进程崩溃可能丢失已被接受但仍留在 inbox、尚未写入会话日志的初始提示词或 follow-up。会话和描述符可能保留，因此后续获得授权的消息仍可冷恢复 child，但丢失的消息不会自动回放。恢复已接受但未完成或未写入日志的消息需要持久化 inbox 协议，本提案不隐含该能力。
+
+### 范围
+
+MVP 覆盖可继续的进程内 child，一次性委派保持不变。远程提供方必须具备单独的激活 handle，以及等价的认证控制与 child-first 完全停稳契约，才能支持同样的行为。
+
+MVP 不新增 subagent steering 操作、报告工具、从 child 到 parent 的内容投递、自动唤醒 parent、持久化邮箱、跨进程 lease、中断 inbox 工作的自动回放、团队权限、工作流权限、公开 subagent 取消操作、新的在线激活数量或后代总数限制，以及运行时缓存。现有委派深度策略保持不变。
+
+## 曾考虑的替代方案
+
+**保留由 Task 支撑的激活。** Task 可以提供通用状态、结果收集和取消，但使用 Task 投递会话会产生第二条队列，并重复轮次所有权。本提案放弃这些通用 Task 控制，让 Agent inbox 成为唯一执行顺序。
+
+**每个 `next-turn` 创建一次激活。** 这会恢复独立的结果与取消边界，但需要在 Agent inbox 旁维护管理器 FIFO，还会使所保留的 Agent 跨越人为划分的激活边界。每个驻留周期对应一次激活更小，也直接跟随 `AgentHandle` 生命周期。
+
+**等待期间 dispose Agent。** child 仍属于上一个进程内所有权图时重建 parent，需要持久化所有权与拆卸协议。只为尚未完成的所有权图保留 `AgentHandle`，可以在不让已结算历史驻留的前提下，保留 child-first 拆卸。
+
+**让提供方通过 Agent handle 创建、恢复 child 或投递消息。** 初始提供方只持有 `prepareContinuable()` 及其分离式创建规格这一项差异：child 是全新启动，还是带有 parent 前缀。管理器必须通过私有 activation-owner 作用域自行调用 `ctx.agents.create()`，使该作用域成为每个 handle 的结构化所有者。持久化的进程内会话已经包含初始前缀及通用重建描述符，消息投递则属于 Agent inbox。让提供方持有任何后续 handle、`SubagentRun` 或消息所有权，会保留一条没有 MVP 行为可承载的 seam，还会因不必要的在线 parent 输入使用户冷恢复更加复杂。
+
+**在 MVP 中增加报告投递。** 可重复调用的面向模型工具与该生命周期兼容，但静默投递还是唤醒投递、接收方选择、确认、持久性和重试行为都是独立的产品决策。延后该工具，可以让首个版本专注于会话准入与驻留，又不限制后续策略。
+
+**将 `SessionHeader.parentSession` 视为在线所有权。** 持久化谱系不能证明历史 parent 当前持有 child。在线 parent 的 `ownedChildren` 成员关系会记录进程内关系，而不改变持久化来源。
+
+**在单独的 link 中保留确切的 parent Agent。** parent 激活已经持有自身 `AgentHandle`，而且 `ownedChildren` 会在 child 仍然在线时阻止该激活 dispose。因此，通过会话 id 解析 parent 已经足够，也可以避免冗余的运行时引用。
+
+**为 parent 消息维护单独队列。** 第二个 FIFO 会让它和 Agent 已接受的用户消息之间顺序不明确。单个 Agent inbox 为两种来源提供唯一且可观察的顺序。
+
+**在 MVP 中暴露 subagent steering。** 用户 steering 可以是严格且仅限在线使用的宿主操作，但 parent steering 需要当前轮次控制方状态，以保护由用户控制的轮次。首个版本将每条继续执行消息都排队，可以避免引入该状态及其准入竞争。后续 UI 可以新增一项仅限用户的独立操作，而不改变 follow-up 排序。
+
+**返回 subagent 专属的投递路由。** `started`、`queued` 和 `resumed` 等标签重复了激活与 inbox 状态，却没有给调用方提供独立结果。复用 `AgentMessageId` 和现有 inbox 事件，可以让投递关联继续由其所属的 Agent 契约承载。
+
+**使用 child 引用计数。** 计数无法识别哪个 child 仍持有拆卸工作，也允许重复递减错误。身份集合会显式保留取消和 dispose 义务。
+
+## 验收标准
+
+- 可继续 child 至多拥有一个在线激活和一个 Agent inbox；继续执行管理器没有激活 FIFO 或 queued 激活状态。
+- `SubagentProvider.prepareContinuable?()` 只返回分离式 `ContinuableCreateSpec`；配置为 continuable 时要求具备该能力，而 `backgroundMode` 仍是独立的策略选择。
+- 管理器通过私有 activation-owner 作用域调用 `ctx.agents.create()`，安装返回的 `AgentHandle` 并建立 parent 所有权，调用 `Agent.followup(initialPrompt)`，然后在 inbox 接受消息并产生 `AgentMessageId` 时返回 `{ childId, messageId }`，而不等待轮次开始或消息写入会话日志。
+- 初始提示词被 inbox 接受前的每条失败路径都会导致操作被拒绝且不返回 id，并回滚已创建的任何 handle、激活和 parent `ownedChildren` 成员关系。
+- 冷恢复由继续执行管理器调用 `ctx.agents.resume()`，绝不通过初始 subagent 提供方分发；`SubagentProvider.resume?()` 和 `SubagentProviderResumeRequest` 均不存在。
+- 可继续激活直接持有 `AgentHandle`，绝不创建、包装或保留 `SubagentRun`；`SubagentProvider.start()` 和 `SubagentRun` 只用于 one-shot，且没有 `SubagentRun.steer?()`。
+- 用户可以在不加载历史 parent 的前提下冷恢复持久化 child。
+- `followup()` 只接受可信 parent 或用户权限；持久化消息来源信息不能授权投递。
+- Parent 和用户的继续执行消息始终使用 `Agent.followup()` 并共享其 inbox FIFO，包括一种来源排在另一种来源之后，以及 child 已有开放轮次的情况。
+- `ctx.subagents.followup()` 及其 `send_message` 适配器只返回已接受的 `AgentMessageId`；继续执行层不接受投递 target，也不定义 subagent 专属路由结果。
+- MVP 不暴露公开 subagent 取消操作；调用方 signal 只能在 inbox 接受消息前停止 start 和 follow-up，宿主和管理器拆卸则保留 child-first 全局清理。
+- MVP 不暴露 subagent steering 操作或当前轮次控制方状态。
+- 带有在线所持 child 的空闲 Agent 会产生 `waiting` 激活，其 `AgentHandle` 继续保留。
+- 向 `waiting` 投递 `next-turn` 会唤醒同一个激活；完成 dispose 后投递消息会冷恢复新激活。
+- 每个由继续执行管理器管理的 parent 激活只会在直接持有的所有 child 激活完成 `AgentHandle` dispose 后进行 dispose；顶层 Agent 不加入等待图。
+- 激活最终结算时，只有 `ctx.sessions.flush(child.session) === true` 才确认持久性；`false` 和 rejection 会报告 `DURABILITY_FAILED`，但仍会 dispose child handle 并释放 parent 所有权，使持久性失败不会泄漏 `waiting` 激活。
+- 宿主和管理器拆卸会同步进入 draining，拒绝新的物化和投递，停止由管理器负责的对外通知，按 child-first 顺序 dispose 处于快照中的整个在线激活森林，即使个别分支失败也会等待所有分支，之后才 dispose 顶层 Agent 和管理器作用域；私有 activation-owner 作用域会确保 Cordis effect 的逆序撤销不破坏该顺序，每次激活使用一个记忆化的 dispose promise，使并发的正常结算保持幂等。
+- MVP 不暴露 `report` 工具，不提供从 child 到 parent 的内容投递，也不自动唤醒 parent。
+- 会话日志只能根据准入来源重建实际写入的消息；已被 inbox 接受但未写入日志的消息没有重启保证。
+- 可继续 subagent 路径不创建或依赖 Task、`TaskId`、Task 完成通知、Task 取消或中间的带结果执行包装层。
+- 单元覆盖固定 `startContinuable()` 在 inbox 接受消息时的返回边界、每条接受前失败路径的完整回滚、接受前后两个阶段的调用方 signal 所有权，以及已接受但未写入日志的消息不会自动回放。
+- 单元覆盖固定仅由驻留状态决定的路由表、单 inbox 顺序、通过 inbox 事件关联 `AgentMessageId`、在开放轮次期间 follow-up、等待唤醒、冷恢复、所有权注册与释放、child-first dispose、发送与 dispose 的竞争、最终持久性检查点返回 `false` 和 rejection 时都不泄漏所有权，以及不存在公开 subagent 取消、steering 和报告工具这一事实。
+- 一项无密钥整套应用快照覆盖 parent 委派、parent 与用户混合的 follow-up 排队、不存在 subagent steering、报告投递和自动唤醒 parent、保留等待中的 `AgentHandle` 以及 child-first dispose。
+
+## 风险
+
+移除 Task 会放弃通用后台工作检查、结果收集和精确 Task 取消。如果这些产品功能成为需求，就需要不会重新引入第二条执行队列的请求 ticket 或 inbox 能力。
+
+在后代运行期间保留激活，会按尚未完成所有权图的规模消耗 Agent 资源。现有委派深度策略仍会限制嵌套层级，但 MVP 不新增在线激活数量或后代总数限制；已结算的历史会话不保留 `AgentHandle`。
+
+进程内 inbox 和所有权图无法协调两个 harness 进程。允许多个进程并发访问同一持久化存储的部署，仍需要持久化 lease 和邮箱协议。
+
+没有报告投递时，完成 child 轮次既不会把内容发送给历史 parent，也不会唤醒它。输出会保留在持久化 child 会话中，直至调用方检查该 transcript 或提交另一个经过授权的轮次。后续报告工具可以增加静默投递或唤醒投递，而无需改变激活生命周期。
+
+将每条继续执行消息排队，意味着 parent 无法立即纠正正在进行的 child 轮次；纠正操作会在下一个轮次执行。后续仅限用户的 UI steering 操作可以缩短该延迟，而无需在 MVP 中引入 parent 与用户之间的控制方策略。
+
+最终持久性检查点失败时，运行时所有权图仍可完成 drain，但持久化 child 状态会缺失或陈旧。该失败会以 `DURABILITY_FAILED` 的形式被观测到；重试与修复需要单独的恢复设计。

Subject: [PATCH 363/557] test(subagent): rewrite continuation spec for
 activation lifecycle

Covers the inbox-acceptance return boundary, pre-acceptance rollback,
caller-signal ownership on both sides of acceptance, residency-only routing,
single-inbox FIFO ordering across parent and user origins, waiting wakeup with
a retained handle, cold resume without the historical parent, ownership
registration and release, child-first disposal, send-versus-dispose races,
durability failure without an ownership leak, per-epoch lifecycle pairing, and
the absence of cancellation, steering, and report surfaces.

Subject: [PATCH 364/557] test(subagent): update service, send_message, and
 delegation specs

The continuable path has no Task, so send_message reports a queued next turn
and continuable delegation returns only the durable child id. Pins that a
follow-up queues behind an open turn rather than steering it, and that a
non-parent caller is rejected.

Also makes startContinuable/followup reject rather than throw synchronously
when continuation services are absent, so callers have one failure mode.

 The subagent seam — an agent delegating work to a child agent. Like [bash](bash.md) it is **one optional capability**, not part of the agent-loop spine, so its vocabulary lives here rather than in [core.md](core.md). But it differs from every other seam on one axis: **multiple provider implementations coexist** in one context, registered by name (`ctx.subagents`), where bash allows only one executor. The registry shape mirrors the [LLM adapter registry](llm-streaming.md), not the single-service bash executor.
 
-Interface: [dsh-subagent](../../packages/subagent/subagent) (`ctx.subagents` + the vocabulary below). Implementations are sibling packages (`dsh-subagent-spawn`, `-fork`, `-acp`); the model-facing consumers are [dsh-tool-subagent](../../packages/subagent/tool-subagent) (per-provider delegation) and [dsh-tool-subagent-control](../../packages/subagent/tool-subagent-control) (the optional global `send_message`). The same `ctx.subagents` service owns continuable-child orchestration through an internal Task-backed manager. The rationale lives in [the subagent Agent Note](../../.agents/notes/implemented/feature/2026-06-21-subagent-capability-seam.md), [the continuable background subagents Agent Note](../../.agents/notes/implemented/feature/2026-07-21-continuable-background-subagents.md), and [the merged-service Agent Note](../../.agents/notes/implemented/simplification/2026-07-26-merge-subagent-control-service.md).

-## The start request

 The tool layer builds this request from the model input and its own config; the service validates it against the named provider before `start`. Required `parent` supplies the session cwd, lineage, and delegation depth. Optional output schema, depth, tool filter, and persona require matching capability flags.

+## Continuable children and activations
+
+A **continuable background subagent** is one durable child Session with at most one process-local **Activation** — a residency epoch for a reconstructed child Agent. An Activation is not a request, result, cancellation, or Task boundary: it may execute many FIFO turns and stays resident while descendants it created are still running. The continuation manager owns activation admission, authority, the live ownership graph, cold resume, and child-first disposal; the Agent loop owns all turn ordering and execution. No continuable path creates a Task or an intermediate result-bearing wrapper.
+
+```text
+persisted Session
+  -> optional live Activation
+       -> one retained AgentHandle
+       -> Agent inbox as the only turn FIFO
+       -> zero or more owned child Activations
 ```
 
-## Continuable children and provider resume
+`SubagentService.startContinuable()` reserves the stable child id, snapshots the versioned `subagent/descriptor` payload, asks the named provider for its detached `ContinuableCreateSpec`, creates the child Agent through a private activation-owner scope, establishes any continuable-parent ownership, and submits the initial prompt. It resolves with `{ childId, messageId }` when inbox acceptance yields the message id — without waiting for the turn to start or for the message to enter the Session log. Every failure before that acceptance rejects with neither id, disposing any created handle and rolling back the Activation and parent ownership.
 
-A **continuable background subagent** is a durable child session with a series of Task-backed activations. `SubagentService.startContinuable()` allocates the stable child id, snapshots the versioned `subagent/descriptor` payload, and passes both through the provider-facing start request; the provider publishes exactly that id and appends the descriptor before the initial prompt is admitted. `SubagentService.followup()` mirrors the intent verb on `Agent`: it steers a live activation or privately dispatches a resolved provider resume after loading and authorizing a stopped child. An internal manager owns descriptor lookup and Task association only while `ctx.tasks` and `ctx.agents` exist; persistence is required per continuation operation, not to load the provider registry. `startContinuable()` returns both identities, while `followup()` reports whether the content `steered` the existing Task or `started` a fresh one. Every sender supplies a `MessageSource` and cancellation signal through one options object; abort while live delivery awaits admission cancels the shared activation and rejects after quiescence. The optional model-facing tool uses `CoordinatorMessageSource` and its tool-execution signal, while a human adapter uses `{ kind: 'user' }` and its interaction signal.
+`SubagentService.followup()` is the sole continuation-message operation, and routing depends only on Activation residency:
+
+| Activation state | Sender | `followup` |
+|---|---|---|
+| `running` | parent or user | enqueue in the same Activation |
+| `waiting` | parent or user | wake the same Activation |
+| no Activation | parent or user | cold-resume a new Activation |
+
+`running` means the Agent has an active admission or turn, or waking inbox work; `waiting` means it is quiescent but still owns at least one child Activation that has not completed disposal; `settled` means quiescent with every owned child disposed, at which point the manager disposes the `AgentHandle` and removes the Activation. The manager derives these from Agent quiescence and the owned-child set rather than maintaining a second execution state machine, and `activationState()` reports the current value (`undefined` when no Activation is live).
+
+The Agent inbox is the only queue. Every continuation message becomes one `Agent.followup()` FIFO turn, so parent and user messages share one observable order and a follow-up cannot redirect a turn already underway. Successful delivery returns the accepted `MessageId`; the existing `agent/inbox/enqueue`, `agent/inbox/dequeue`, and `agent/inbox/discard` events remain the message-lifecycle observations, and the continuation layer defines no subagent-specific delivery route.
+
+Authority is supplied by a trusted host interaction or an exact live Agent tool context. The parent variant is admitted only when the authenticated Agent is the durable child's direct parent recorded in `SessionHeader.parentSession`; only a trusted host adapter can supply user authority. `MessageSource` and `senderSessionId` are durable provenance after admission and grant no authority — the optional model-facing tool uses `CoordinatorMessageSource`, while a host adapter uses `{ kind: 'user' }`. User authority may cold-resume a child without loading its historical parent.
+
+For both operations the caller signal owns lookup, materialization, and admission only until inbox acceptance. Afterwards the manager owns the Activation independently: later caller cancellation neither cancels the accepted turn nor disposes the child, and the seam exposes no public subagent cancellation or steering operation.
+
+Every Activation owns its `AgentHandle` and an `ownedChildren: Set`; because one Session has at most one live Activation, the child Session id identifies the live child without another runtime-incarnation reference. Starting a child or submitting parent-originated work registers the child in a continuation-managed parent's set before the child can run, and that parent cannot settle while the set is non-empty. A top-level or other non-continuation Agent has no Activation and stays outside the waiting graph. Child release happens only after the child Agent is quiescent, every child of that child is disposed, the final durability checkpoint settles, and the child's `AgentHandle` completes disposal.
+
+Only `ctx.sessions.flush(session) === true` confirms durability; `false` or rejection reports `DURABILITY_FAILED`. Either way the manager still disposes the handle and releases ownership, because retaining a failed child would permanently pin its ancestors in `waiting` — the persisted child state may then be missing or stale on a later resume. `drainContinuable()` is the lifecycle-wide stop path: it closes admission synchronously, then disposes every live Activation forest child-first, awaiting every branch despite individual failures. Durable child Sessions survive that process-local teardown.

+The implementation pins these behaviors:
 
 - A continuable child has at most one live Activation and one Agent inbox; the continuation manager has no Activation FIFO or queued Activation state.
 - `SubagentProvider.prepareContinuable?()` returns only a detached `ContinuableCreateSpec`; configured continuable mode requires that capability, while `backgroundMode` remains an independent policy choice.
-- The manager calls `ctx.agents.create()` through its private activation-owner scope, installs the returned `AgentHandle` and parent ownership, calls `Agent.followup(initialPrompt)`, and returns `{ childId, messageId }` when inbox acceptance yields the `AgentMessageId`, without waiting for turn start or a Session-log write.

 - Every failure before initial-prompt inbox acceptance rejects without ids and rolls back any created handle, Activation, and parent `ownedChildren` membership.
 - Cold resume calls `ctx.agents.resume()` from the continuation manager and never dispatches through the initial subagent provider; `SubagentProvider.resume?()` and `SubagentProviderResumeRequest` are absent.
 - A continuable Activation directly owns `AgentHandle` and never creates, wraps, or retains `SubagentRun`; `SubagentProvider.start()` and `SubagentRun` remain one-shot-only, without `SubagentRun.steer?()`.
 - A user can cold-resume a persisted child without loading its historical parent.
 - `followup()` accepts only trusted parent or user authority; durable message provenance cannot authorize delivery.
 - Parent and user continuation messages always use `Agent.followup()` and share its inbox FIFO, including when one origin queues behind the other or the child already has an open turn.

+### Accepted costs
 
 Removing Tasks gives up generic background-work inspection, result collection, and exact Task cancellation. If those product features become requirements, they need a request ticket or inbox capability that does not reintroduce a second execution queue.

+The `followup` operation this record names is retained by [Continuable subagents](../feature/2026-07-28-continuable-subagent-conversations.md), which replaces its Task-backed return value with the accepted `MessageId`, its bare-`Agent` parameter with an explicit authority union, and provider `resume` dispatch with `prepareContinuable`.
+
 ## Problem
 
 Merging continuable-child orchestration into `ctx.subagents` left provider dispatch and caller intent on the same public service. `resume(name, request)` accepted a descriptor, authorized parent, durable child id, and activation signal that only the internal continuation manager could resolve correctly. `sendMessage(...)` exposed transport wording rather than the `followup` intent already used by `Agent`, and its separate source and signal parameters widened an operation every caller had to use atomically.

+本记录命名的 `followup` 操作由[可继续的 subagent](../feature/2026-07-28-continuable-subagent-conversations.md)保留，但后者以已接受的 `MessageId` 替换其基于 Task 的返回值，以显式的 authority（授权）联合类型替换裸 `Agent` 参数，并以 `prepareContinuable` 替换提供方 `resume` 派发。
+
 ## 问题
 
 将可继续 child 的编排合并到 `ctx.subagents` 后，提供方分发与调用方意图共存于同一个公开服务中。`resume(name, request)` 接受描述符、已鉴权的 parent、持久化 child id 与激活信号，而只有内部继续执行管理器才能正确解析这些数据。`sendMessage(...)` 暴露的是传输层措辞，而不是 `Agent` 已采用的 `followup` 意图；它还将来源与信号拆成独立参数，扩大了操作接口，而每个调用方都必须以原子方式同时使用二者。

Subject: [PATCH 367/557] docs(subagent): regenerate catalogs for the
 activation-based seam

Adds the new continuable types to the cordis-catalog type-link map and
regenerates the cordis api/service/event catalogs, tool catalog, config
catalog, and doc graphs.

 ### `send_message`
 
-Send a follow-up message to a background subagent by its subagent id. If it is still working, the message joins its current task; if it has finished, this starts a new task that continues the same subagent conversation. Either way the response arrives through the returned task id — collect it with `task_output`. A failure means the message was NOT delivered.
+Send a message to a background subagent by its subagent id, continuing the same conversation. It becomes the subagent's next turn: if it is still working, the message waits until its current turn finishes, so it cannot redirect work already underway. The subagent does not reply to you — read its transcript by its id to see what it did. A failure means the message was NOT delivered.

Subject: [PATCH 368/557] docs(subagent): update package READMEs for the
 activation lifecycle

Rewrites the service API table, authority-versus-provenance contract, residency
routing, and deferred-work list; scopes the in-process driver README to one-shot
runs; and restates both model-facing tools' outputs, which no longer carry a
task id.

Everything else—depth, child creation, optional child customization, result reading, cancellation, and disposal—has one implementation here.

 The driver follows this sequence:
 
 1. Validate the parent depth and optional absolute `maxDepth`, then derive child depth as parent depth plus one and persist it in the child session header.
-2. Call `parent.ctx.agents.create` directly, passing the required request signal into the factory's creation transaction. A continuable request publishes exactly `request.continuation.sessionId` instead of an internally minted id.
-3. During that transaction's unpublished setup window, install the requested persona, tool restriction, structured-output runtime, and — for a continuable request — the prepended one-shot `agent/prompt-submit` contribution. It appends the `subagent/descriptor` event before downstream prompt admission can block or throw; allowed admission opens the initial turn afterward, while the final required checkpoint persists the descriptor even when no turn opens.
-4. Publish the child, retain the returned `AgentHandle`, and drive one task with `child.followup(prompt)` followed by `child.whenIdle()`.
-5. For a continuable start or resume, call `child.ctx.sessions.flush(child.session)` again before returning the result and require its participation result to be `true`. This final confirmation retries events retained after a failed turn checkpoint; if no listener participates or any listener fails, `result` rejects with `SubagentError.code === 'DURABILITY_FAILED'`, retains the checkpoint failure as `cause`, and names the resumability risk in its message. Activation cancellation during this await owns the unpublished result even when the completed turn was already recorded or the checkpoint subsequently fails. Foreground runs keep the loop's best-effort checkpoint behavior.
-6. Read the child's own last assistant message and latest message-triggered turn reason, excluding any fork seed and later plugin-owned between-turn records.
+2. Mint a fresh child session id and call `parent.ctx.agents.create` directly, passing the optional fork seed and required request signal into the factory's creation transaction. During the unpublished setup window, install the requested persona, tool restriction, and structured-output runtime.
+3. Publish the child, retain the returned `AgentHandle`, and drive one task with `child.followup(prompt)` followed by `child.whenIdle()`.
+4. Read the child's own last assistant message and latest message-triggered turn reason, excluding the fork seed prefix so a seeded parent message is never mistaken for child output.
 
 The child gets the parent's working-directory/session lineage and inherits the parent provider, model, and output-token cap unless `request.agentOptions` overrides them. It gets a fresh flat registration scope: parent ownership does not import parent tool restrictions or establish an authority subset.
 
 When the optional sandbox-policy or approval service is composed, the driver snapshots the parent's explicit session override before child creation and appends a source-tagged event during unpublished setup, after any fork history and before session publication. It never copies deployment defaults or one-shot grants; later child switches still win. See the [policy-inheritance decision](../../../.agents/notes/implemented/feature/2026-07-25-subagent-policy-inheritance.md).
 
-## Cold resume
-
-`resumeInProcessRun(request): Promise` reconstructs a persisted continuable child under the live parent's scope: `parent.ctx.agents.resume` loads the child's own transcript through persistence (a fork child's log already contains its seed prefix, so resume never re-forks current parent history), the descriptor's persona and tool filter are reapplied in the unpublished setup window, and the descriptor's `agentProvider`/`agentModel` become the runtime options. The persisted header stays authoritative for lineage and the delegation-depth floor. The activation's result boundary is the resumed log length: only this follow-up turn's output becomes the run result. Publication, final durability confirmation, abort handoff, and disposal follow the same contract as a continuable start.
-
 ## Cancellation and ownership
 
 The required request signal covers both startup and the live run. Before publication, `AgentCreationTransaction` observes it, rolls back, and rejects. The factory detaches that creation-only listener before returning; the driver immediately checks the signal once more before installing a minimal live-run listener, closing the handoff race. After publication, abort cancels the child.
 
 After fulfillment, the caller owns the run. Provider-plugin unload does not revoke it. `dispose()` removes the live abort listener, records cancellation, and delegates to the returned `AgentHandle.dispose()`, whose memoized quiescence transaction stops the loop, removes the agent and session, and unwinds scoped registrations. Cancellation owns every non-completed in-flight outcome and reports `aborted`; an already-completed turn remains completed.
 
-Runs expose confirmed `steer`: a synchronous status check prevents the Agent-level idle fallback from starting an untracked turn, then the run submits through `Agent.steer()` and awaits that exact message's receipt. Fulfillment means a committed child request snapshot admitted the message; terminal turn policy, cancellation, disposal, or a settlement race rejects instead. A synchronously visible structured capture is rejected before submission because its terminal outcome is already authoritative. The run never falls through from rejected live delivery to a later queued turn or cold resume.
-
 ## Spawn and fork inputs
 
 `InProcessRunOptions` is `{ seed?: SessionEvent[] }`. Spawn omits it. Fork supplies a balanced completed-turn prefix and records its length so the result reader never mistakes a seeded parent message for child output.

 ## 启动契约
 
@@ -11,28 +11,19 @@
 驱动器按以下顺序运行：
 
 1. 校验父 agent 深度和可选的绝对 `maxDepth`，然后把子 agent 深度推导为父 agent 深度加一，并将其持久化到子 agent 会话 header。
-2. 直接调用 `parent.ctx.agents.create`，把必需的请求信号传入工厂的创建事务。可继续请求会精确发布 `request.continuation.sessionId`，而不是内部生成的 ID。
-3. 在该事务未发布的设置窗口中，安装请求的 persona、工具限制和结构化输出运行时；对于可继续请求，还会前置安装一次性的 `agent/prompt-submit` 贡献。它会在下游 prompt admission 能够阻止请求或抛出异常之前追加 `subagent/descriptor` 事件；admission 获准后才会开启初始轮次，即使没有轮次开启，最终的必需检查点仍会持久化该描述符。
-4. 发布子 agent，保留返回的 `AgentHandle`，并通过先调用 `child.followup(prompt)`、再调用 `child.whenIdle()` 来驱动一项任务。
-5. 对于可继续启动或恢复，在返回结果前再次调用 `child.ctx.sessions.flush(child.session)`，并要求其参与结果为 `true`。这次最终确认会重试轮次检查点失败后保留的事件；如果没有监听器参与或任一监听器失败，`result` 会以 `SubagentError.code === 'DURABILITY_FAILED'` 拒绝，将检查点失败保留为 `cause`，并在消息中说明恢复风险。即使已记录完成的轮次，或随后检查点失败，等待期间发生的激活取消仍决定尚未发布的结果。前台运行保留循环的尽力检查点行为。
-6. 读取子 agent 自身最后一条 assistant 消息，以及由消息触发的最新轮次原因；排除任何 fork 初始内容和后续由插件拥有的轮次间记录。
+2. 生成全新的子 agent 会话 id，并直接调用 `parent.ctx.agents.create`，把可选的 fork 初始内容和必需的请求信号传入工厂的创建事务。在未发布的设置窗口中，安装请求的 persona、工具限制和结构化输出运行时。
+3. 发布子 agent，保留返回的 `AgentHandle`，并通过先调用 `child.followup(prompt)`、再调用 `child.whenIdle()` 来驱动一项任务。
+4. 读取子 agent 自身最后一条 assistant 消息，以及由消息触发的最新轮次原因；排除 fork 初始内容前缀，确保作为初始内容的父 agent 消息绝不会被误认为子 agent 输出。
 
 子 agent 会获得父 agent 的工作目录／会话谱系；除非 `request.agentOptions` 覆盖，否则还会继承父 agent 的提供方、模型和输出 token 上限。它获得全新的扁平注册作用域：父级所有权不会导入父 agent 的工具限制，也不会建立权限子集。
 
 当组合中挂载了可选的沙箱策略或审批服务时，驱动器会在创建子 agent 前对父级的显式会话覆盖项获取快照，并在未发布的设置阶段追加一条带来源标记的事件，使其位于所有 fork 历史之后、会话发布之前。它绝不复制部署默认值或一次性授权；子 agent 后续的切换仍然优先。参见[策略继承决策](../../../.agents/notes/implemented/feature/2026-07-25-subagent-policy-inheritance.md)。
-
-## 冷恢复
-
-`resumeInProcessRun(request): Promise` 会在当前父级作用域下重建持久化的可继续子 agent：`parent.ctx.agents.resume` 通过持久化层加载子 agent 自身的 transcript（文本记录；fork 子 agent 的日志已经包含初始前缀，因此恢复绝不会再次 fork 当前父级历史），在未发布的设置窗口中重新应用描述符中的 persona 和工具过滤器，并把描述符中的 `agentProvider` / `agentModel` 作为运行时选项。持久化 header 对谱系和委派深度下限保持权威性。activation 的结果边界是恢复后日志的长度：只有此次后续轮次的输出会成为运行结果。发布、最终持久性确认、中止交接和 dispose 遵循与可继续启动相同的契约。
-
 ## 取消与所有权
 
 必需的请求信号同时覆盖启动阶段和实时运行。发布前，`AgentCreationTransaction` 会观察该信号、回滚并拒绝。工厂返回前会移除仅用于创建阶段的监听器；驱动器随即再次检查信号，然后安装最小化的实时运行监听器，从而消除交接竞态。发布后，中止会取消子 agent。
 
 兑现后，调用方拥有该运行。提供方插件卸载不会撤销它。`dispose()` 会移除实时中止监听器、记录取消，并委托给返回的 `AgentHandle.dispose()`；后者通过可复用的完全停稳事务停止循环、移除 agent 和会话，并展开有作用域的注册。取消决定所有尚未完成的进行中结果，并将其报告为 `aborted`；已经完成的轮次仍保持完成状态。
 
-运行公开确认式 `steer`：同步状态检查会阻止 Agent 层的空闲 fallback 启动未跟踪轮次，随后运行通过 `Agent.steer()` 提交消息，并等待该准确消息的回执。兑现表示某个已提交的子 agent 请求 snapshot 接纳了消息；结束轮次的策略、取消、dispose（资源释放）或结算竞态会改为拒绝。已同步可见的结构化捕获会在提交前被拒绝，因为其终态结果已经具有权威性。实时投递被拒绝后，运行绝不会转而进入之后的排队轮次或冷恢复。
-
 ## Spawn 与 fork 输入
 
 `InProcessRunOptions` 的形态为 `{ seed?: SessionEvent[] }`。spawn 省略该值。fork 提供平衡的已完成轮次前缀，并记录其长度，确保结果读取器不会把作为初始内容的父 agent 消息误认为子 agent 输出。

 ## Service API
 
-`SubagentService` has six main operations:
+`SubagentService` has these operations:
 
 | Member | Meaning |
 |---|---|
 | `registerProvider(provider)` | Register one trusted same-process implementation by name. Registration is effect-scoped; removing it prevents new starts but does not revoke runs already returned to callers. Duplicate names fail loud. |
 | `getProvider(name)` | Return the provider, or `undefined` when absent. |
 | `list()` | Return provider names in insertion order. |
-| `start(name, request)` | Validate an ordinary caller request, then await the provider until a real child is ready. Fulfillment returns a holder-owned `SubagentRun`; rejection means the provider has already cleaned every partial startup resource. Continuation state cannot enter through this operation. |
-| `startContinuable(spec)` | Allocate a durable child id and register its initial Task-backed activation. Requires `ctx.tasks`, `ctx.agents`, session persistence, and a resumable provider. |
-| `followup(parent, childId, content, { source, signal })` | Follow up with a durable child, matching `Agent.followup()` terminology. It steers the current activation or starts a new Task that cold-resumes the child. Aborting `signal` while live delivery awaits admission cancels the shared activation and rejects after quiescence. Requires `ctx.tasks` and `ctx.agents`; cold resume also requires session persistence. |
+| `start(name, request)` | Validate an ordinary caller request, then await the provider until a real one-shot child is ready. Fulfillment returns a holder-owned `SubagentRun`; rejection means the provider has already cleaned every partial startup resource. Continuable children never enter through this operation. |
+| `startContinuable(spec)` | Establish one durable continuable child and deliver its initial prompt. Resolves with `{ childId, messageId }` when the child's inbox accepts that prompt, without waiting for the turn to start or for the message to reach the Session log; any earlier failure rejects with no ids and rolls the child back entirely. Requires `ctx.agents`, session persistence, and a provider with the `prepareContinuable` capability. |
+| `followup(authority, childId, content, { source, signal })` | Deliver one later message to a continuable child as its next FIFO turn, matching `Agent.followup()` terminology, and return the accepted `AgentMessageId`. A resident child's inbox accepts it directly (waking a `waiting` Activation); an absent one cold-resumes from its persisted Session. Requires `ctx.agents`; cold resume also requires session persistence. |
+| `activationState(childId)` | Read one durable child's live residency state (`running`, `waiting`, or `settled`), or `undefined` when no Activation is live. |
+| `drainContinuable()` | Close continuable admission synchronously, then dispose every live Activation forest child-first. A host calls this before disposing top-level agents so no descendant outlives the runtime that owns its teardown. An aggregate error surfaces after every branch settles when any failed. |
 
-`SubagentStartRequest.signal` is required and is the canonical cancellation channel. An abort before publication makes `start()` reject after rollback; an abort after publication cancels the live child. The request may also select a model, require structured output, cap delegation depth, restrict child tools, or set a child persona. Only the internal continuation manager can add a stable child id and durable descriptor to the provider-facing `SubagentProviderStartRequest`; cold provider resume is likewise private dispatch after descriptor lookup and parent authorization.
+`SubagentStartRequest.signal` is required and is the canonical cancellation channel for a one-shot `start`. An abort before publication makes `start()` reject after rollback; an abort after publication cancels the live child. The request may also select a model, require structured output, cap delegation depth, restrict child tools, or set a child persona. For a continuable start or follow-up, the caller signal owns lookup, materialization, and admission only until inbox acceptance; afterward the manager owns the Activation independently, so later caller cancellation neither cancels the accepted turn nor disposes the child.
+
+Authority for continuable operations comes from a trusted host interaction or an exact live Agent tool context: `SubagentAuthority` is `{ kind: 'parent', agent }` or `{ kind: 'user' }`. The `source` on a follow-up is durable provenance retained on the delivered message and grants no authority. Parent authority requires the exact live direct parent recorded in the child's durable header; user authority may continue any child, and may cold-resume it without loading its historical parent.
 
 Same-process requests, descriptors, results, and event payloads are trusted typed values borrowed as immutable. The service does not clone or freeze them; serialization and hostile-input validation belong at actual process, worker, persistence, and model boundaries.
 
 ## Capabilities

+Start-time features are advertised in `provider.capabilities` because the service must reject an unsupported one-shot request before child creation:
 
 - `outputSchema` — enforce a structured final result.
 - `depthLimit` — enforce `maxDepth`.
 - `toolFilter` — apply the requested child tool restriction.
 - `persona` — apply a per-child persona.
 
-Runtime features are optional methods whose presence is the capability check: `SubagentRun.steer?` fulfills only after a request snapshot in the active child admits the message and rejects rather than queueing an untracked turn, while `SubagentProvider.resume?` reconstructs a persisted continuable child. A run represents one disposable activation, so it deliberately has no cold-resume operation — a disposed run cannot be reconstructed after restart.
+Continuable creation is the optional `SubagentProvider.prepareContinuable?()` method: its presence is the capability check, so the service rejects a configured continuable start on a provider without it, while a provider that has it may still serve ordinary one-shot delegations. The method returns only a detached `ContinuableCreateSpec` (`{ seed? }`) — data, never a capability: it carries no Agent, `AgentHandle`, prompt delivery, result, disposal, or resume operation, because the continuation manager owns identity reservation, composition, Agent creation, prompt delivery, cold resume, ownership, and disposal after preparation. A one-shot `SubagentRun` represents one disposable foreground delegation with one result and no cold-resume operation.
 
 ## The durable descriptor
 
-The seam owns the versioned `subagent/descriptor` session event vocabulary (`src/descriptor.ts`): `snapshotSubagentDescriptor()` validates and detaches the declared composition before any Task exists, and `foldSubagentDescriptor()` validates the complete current-version payload before recovering it from a loaded child log. Malformed current-version payloads fail before provider dispatch; unsupported versions make the child non-resumable. The payload records the provider name, resolved child `agentOptions.provider`/`model`, and optional `persona`/`toolFilter` — explicit fields, never the merge-extensible `AgentOptions` object, so an unrelated extension value cannot break continuation. It omits `subagentDepth` (the persisted header's `delegationDepth` is the monotone floor) and `outputSchema` (an activation's result contract). The event is log-only: no `surfaceOp`, absent from model history, and retained by the append-only log across compaction.

-`provider.start(request): Promise` is the ownership-transfer boundary. Before fulfillment, the provider owns setup and must cancel, roll back, and quiesce partial resources on every failure.

-`SubagentRun.result` resolves to `{ output, structured?, stopReason }`. Child-level failures resolve with a non-`completed` reason; only an infrastructure fault that the seam cannot represent may reject. For a continuable activation, a completed result also confirms that the provider made its final state durable; a failed required checkpoint rejects as infrastructure rather than publishing unconfirmed output. `dispose()` is idempotent, cancels remaining work, and waits for the child resources to quiesce.

-A local run publishes an ordinary child agent/session before `start()` fulfills, returns that shared session id as `SubagentRun.id`, exposes the exact child as `SubagentRun.localAgent`, and records `request.parent.session.id` in the child's `parentSession` header. A continuable start publishes exactly the service-allocated `continuation.sessionId`. Remote providers instead mint a parent-scoped lifecycle id and return `localAgent: undefined`.

Remote providers instead mint a parent-scoped lifecycle id and return `localAgent: undefined`.
 
-The service emits `subagent/start` only after an ordinary start or privately dispatched provider resume has fulfilled. It attaches the result observer before that synchronous notification, so even an already-settled child still produces `subagent/start` before `subagent/end`. The pair shares a service-minted `runId`; its `local` flag is snapshotted from the provider's exact `localAgent`, so observers never infer run identity or locality from reusable provider/session names.
+## Continuable children and Activations
 
-Run events are scoped to the delegating parent. Every listener is independently contained: a synchronous throw or rejected returned promise is logged without starving peer listeners or changing the run.
+A continuable child has one durable Session and at most one process-local **Activation** — one residency epoch for a reconstructed child Agent, not a request, result, cancellation, or Task boundary. The Agent inbox is the only turn queue, so the continuation manager owns residency while the Agent loop owns all turn ordering and execution. No continuable path creates a Task or an intermediate result-bearing wrapper.
+
+The public residency state has three values derived from Agent quiescence and the owned-child set, not a second state machine: `running` (an active admission, open turn, or waking inbox work), `waiting` (quiescent but still owning at least one undisposed child), and `settled` (quiescent with every owned child disposed, so the manager disposes the `AgentHandle` and removes the Activation). Every continuation message uses `Agent.followup()` and becomes one FIFO turn, so parent and user messages share one observable order with no steering of the current turn. Routing depends only on residency: `running` enqueues, `waiting` wakes the same Agent, and an absent Activation cold-resumes a new one.
+
+The manager reserves the child identity, resolves the durable descriptor, calls `ctx.agents.create()` (or `ctx.agents.resume()` for cold resume) through a private activation-owner scope, installs the returned `AgentHandle` in the Activation, establishes any continuable-parent ownership, and then submits the prompt. Cold resume never dispatches through a provider — the persisted Session already holds the initial prefix and the folded descriptor is the whole reconstruction input — so a user can cold-resume a persisted child without loading its historical parent.
+
+A continuation-managed parent Activation records each child Session id in an `ownedChildren` set before the child can run and disposes only after every owned child Activation completes `AgentHandle` disposal (child-first). Top-level and other non-continuation Agents have no Activation and stay outside this waiting graph. Final settlement treats only `ctx.sessions.flush(child.session) === true` as durability confirmation; `false` or rejection reports `DURABILITY_FAILED` and still disposes the handle and releases ownership, because retaining a failed child would permanently pin its ancestors in `waiting`.
+
+## Lifecycle events
+
+The service emits a `subagent/start`/`subagent/end` pair for each one-shot run and each continuable Activation's residency epoch, so continuable children are observable with the same vocabulary as one-shot runs without exposing whether the manager materialized, woke, or cold-resumed them. For a one-shot start it attaches the result observer before the synchronous `subagent/start`, so even an already-settled child still produces `subagent/start` before `subagent/end`; a continuable epoch that never becomes resident emits only the terminal edge, because it has no start edge to pair. The pair shares a service-minted `runId`; the `local` flag is snapshotted from the provider's exact `localAgent` (always true for a continuable child), so observers never infer run identity or locality from reusable provider/session names.
+
+Run events are scoped to the delegating parent; a user-resumed continuable child has no delegating parent, so its lifecycle reaches unscoped listeners globally. Every listener is independently contained: a synchronous throw or rejected returned promise is logged without starving peer listeners or changing the run.
 
 Provider additions and removals also emit `subagent/provider-added` and `subagent/provider-removed`. Consumers such as the model-facing tool use those events because Cordis may load sibling plugins concurrently; configuration order does not prove registration order.
 
 ## Collection model
 
-The model-facing tool collects synchronously by default: it awaits the child result and disposes the run before returning. One-shot background delegation registers a plain Task in the tool. Continuable background delegation calls `ctx.subagents.startContinuable()`, whose internal manager exists only while `ctx.tasks` and `ctx.agents` are available; session persistence is resolved per continuation operation. Collection and cancellation use the shared task tools. See the [background subagent tasks Agent Note](../../../.agents/notes/implemented/feature/2026-07-08-background-subagent-tasks.md), the [continuable background subagents Agent Note](../../../.agents/notes/implemented/feature/2026-07-21-continuable-background-subagents.md), the [merged-service Agent Note](../../../.agents/notes/implemented/simplification/2026-07-26-merge-subagent-control-service.md), the [capability-seam Agent Note](../../../.agents/notes/implemented/feature/2026-06-21-subagent-capability-seam.md), and `src/types.ts` for the complete contracts.
+The model-facing tool collects synchronously by default: it awaits the child result and disposes the run before returning. One-shot background delegation registers a plain Task in the tool, whose generic status, collection, and cancellation tools own later interaction. Continuable background delegation calls `ctx.subagents.startContinuable()` and returns only the durable child id; the child owns its own turns from inbox acceptance, so there is no Task, no result promise, and no public subagent cancellation — a caller sends later work with the `send_message` follow-up tool, and the durable child Session remains the source of the child's detailed output. The continuation manager exists only while `ctx.agents` is available, and session persistence is resolved per continuation operation.

+- **ACP children remain one-shot** — an ACP `prepareContinuable` requires persisting the remote session id in provider-specific descriptor data and a per-child continuation advertisement, since ACP `loadSession` support is negotiated per child rather than established by the method's presence. Remote providers also require a separate Activation ownership contract with equivalent authenticated control and child-first quiescence before they support continuable children.
+- **No report delivery** — the MVP exposes no `report` tool, child-to-parent content delivery, or automatic parent wakeup; a completed child turn leaves its output in the durable child Session until a caller inspects that transcript or submits another authorized turn.
+- **No subagent steering** — every continuation message opens a later FIFO turn, so a parent or user cannot redirect a turn already underway; the manager stores no current-turn controller state.
+- **Process-local residency** — the Activation inbox and ownership graph do not coordinate two harness processes; concurrent access to one persistence store still requires a durable mailbox and cross-process lease protocol.
+- **No replay of accepted-but-unlogged messages** — only messages written to the child Session log are reconstructable with their admitted provenance. A crash may lose an accepted initial prompt or follow-up that never reached the log; a later authorized message can cold-resume the child, but the lost message is not replayed automatically.

 ## 服务 API
 
-`SubagentService` 有六个主要操作：
+`SubagentService` 具有以下操作：
 
 | 成员 | 含义 |
 |---|---|
 | `registerProvider(provider)` | 按名称注册一个可信的同进程实现。注册受 effect 作用域约束；移除注册会阻止新的启动，但不会撤销已返回给调用方的运行。重复名称会立即失败。 |
 | `getProvider(name)` | 返回提供方；不存在时返回 `undefined`。 |
 | `list()` | 按插入顺序返回提供方名称。 |
-| `start(name, request)` | 校验普通调用方请求，然后等待提供方，直到真实子 agent 就绪。兑现时返回由持有方拥有的 `SubagentRun`；拒绝表示提供方已清理所有局部启动资源。此操作不允许传入继续执行状态。 |
-| `startContinuable(spec)` | 分配持久化子 agent id，并注册其初始的由 Task 支撑的激活。要求 `ctx.tasks`、`ctx.agents`、会话持久化及可恢复的提供方。 |
-| `followup(parent, childId, content, { source, signal })` | 对持久化子 agent 执行后续操作，术语与 `Agent.followup()` 一致。它会引导当前激活，或启动新 Task 从持久化存储恢复该子 agent。若在在线投递等待准入期间中止 `signal`，则会取消共享激活，并在其完全停稳后拒绝该调用。要求 `ctx.tasks` 和 `ctx.agents`；从持久化存储恢复还要求会话持久化。 |
+| `start(name, request)` | 校验普通调用方请求，然后等待提供方，直到真实的一次性子 agent 就绪。兑现时返回由持有方拥有的 `SubagentRun`；拒绝表示提供方已清理所有局部启动资源。可继续子 agent 绝不通过此操作进入。 |
+| `startContinuable(spec)` | 建立一个持久化可继续子 agent，并投递其初始提示词。子 agent 的 inbox 接受该提示词时，兑现为 `{ childId, messageId }`，无需等待轮次开始或消息写入 Session 日志；此前任何失败都会以无 id 拒绝，并完全回滚该子 agent。要求 `ctx.agents`、会话持久化以及具备 `prepareContinuable` 能力的提供方。 |
+| `followup(authority, childId, content, { source, signal })` | 将一条后续消息作为可继续子 agent 的下一个 FIFO 轮次投递，术语与 `Agent.followup()` 一致，并返回被接受的 `AgentMessageId`。驻留中的子 agent 由其 inbox 直接接受（唤醒处于 `waiting` 的 Activation）；不驻留的则从其持久化 Session 冷恢复。要求 `ctx.agents`；冷恢复还要求会话持久化。 |
+| `activationState(childId)` | 读取某个持久化子 agent 的实时驻留状态（`running`、`waiting` 或 `settled`）；无实时 Activation 时返回 `undefined`。 |
+| `drainContinuable()` | 同步关闭可继续准入，然后以子先于父的顺序 dispose 每一个实时 Activation 森林。host 会在 dispose 顶层 agent 之前调用它，使任何后代都不会比拥有其拆卸职责的运行时存活更久。任一分支失败时，会在所有分支结算后抛出聚合错误。 |
 
-`SubagentStartRequest.signal` 是必填项，也是规范取消通道。发布前中止会使 `start()` 在回滚后拒绝；发布后中止会取消实时子 agent。请求还可以选择模型、要求结构化输出、限制委派深度、约束子 agent 工具或设置子 agent persona。只有内部继续执行管理器才能把稳定子 agent id 和持久化描述符添加到面向提供方的 `SubagentProviderStartRequest`；从持久化存储恢复时，向提供方的请求同样只会在查找描述符并授权父级后由内部管理器分发。

+
+可继续操作的权限来自可信的 host 交互或准确的实时 Agent 工具上下文：`SubagentAuthority` 为 `{ kind: 'parent', agent }` 或 `{ kind: 'user' }`。后续操作上的 `source` 是保留在所投递消息上的持久化来源，不授予任何权限。父级权限要求准确匹配子 agent 持久化 header 中记录的实时直接父级；用户权限可以继续任何子 agent，并且可以在不加载其历史父级的情况下将其冷恢复。
 
 同进程请求、描述符、结果和事件 payload 都是以不可变方式借用的可信类型值。服务不会克隆或冻结它们；序列化和不可信输入校验属于真实的进程、worker、持久化和模型边界。

+## 可继续子 agent 与 Activation
 
-运行事件受执行委派的父级作用域约束。每个监听器都独立隔离：同步抛出或返回的 promise 被拒绝时，只会记录日志，不会阻塞同级监听器或改变运行。
+可继续子 agent 拥有一个持久化 Session 和至多一个进程内 **Activation**——即被重建的子 agent 的一个驻留时段，而不是请求、结果、取消或 Task 边界。Agent inbox 是唯一的轮次队列，因此继续执行管理器负责驻留，而 Agent 循环负责所有轮次排序与执行。任何可继续路径都不会创建 Task 或中间的承载结果的包装器。
+
+公共驻留状态有三个取值，由 Agent 停稳状态和所拥有子集推导，而非第二个状态机：`running`（存在活跃准入、进行中的轮次或唤醒型 inbox 工作）、`waiting`（已停稳但仍拥有至少一个未 dispose 的子 agent）、`settled`（已停稳且所有拥有的子 agent 都已 dispose，因此管理器 dispose `AgentHandle` 并移除 Activation）。每条后续消息都使用 `Agent.followup()` 并成为一个 FIFO 轮次，因此父级和用户消息共享同一个可观察顺序，且不会对当前轮次进行 steering（中途引导）。路由只取决于驻留状态：`running` 入队、`waiting` 唤醒同一 Agent，无 Activation 时则冷恢复一个新的。
+
+管理器预留子 agent 身份、解析持久化描述符，通过私有的 activation-owner 作用域调用 `ctx.agents.create()`（冷恢复时为 `ctx.agents.resume()`），把返回的 `AgentHandle` 安装到 Activation 中，建立任何可继续父级所有权，然后提交提示词。冷恢复绝不通过提供方分发——持久化 Session 已持有初始前缀，折叠后的描述符即是全部重建输入——因此用户可以在不加载历史父级的情况下冷恢复持久化子 agent。
+
+受继续执行管理的父级 Activation 会在子 agent 能够运行之前，把每个子 agent 的 Session id 记录到 `ownedChildren` 集合中，并且只有在每个所拥有的子 agent Activation 完成 `AgentHandle` dispose 之后才会 dispose（子先于父）。顶层及其他非继续执行的 Agent 没有 Activation，处于该等待图之外。最终结算只把 `ctx.sessions.flush(child.session) === true` 视为持久性确认；`false` 或拒绝会报告 `DURABILITY_FAILED`，但仍会 dispose 句柄并释放所有权，因为保留失败的子 agent 会使其祖先永久停留在 `waiting`。
+
+## 生命周期事件
+
+服务会为每次一次性运行以及每个可继续 Activation 的驻留时段发出一对 `subagent/start`/`subagent/end`，因此可继续子 agent 可用与一次性运行相同的词汇观察，且不会暴露管理器是物化、唤醒还是冷恢复了它们。对于一次性启动，它会在同步的 `subagent/start` 之前附加结果观察器，因此即使子 agent 已经结算，也仍会先产生 `subagent/start`，再产生 `subagent/end`；从未驻留过的可继续时段只发出终止边，因为它没有可配对的开始边。这对事件共享服务生成的 `runId`；`local` 标志取自提供方准确 `localAgent` 的快照（可继续子 agent 恒为 true），因此观察器绝不会从可复用的提供方/会话名称推断运行身份或本地性。
+
+运行事件受执行委派的父级作用域约束；用户恢复的可继续子 agent 没有执行委派的父级，因此其生命周期会全局到达无作用域的监听器。每个监听器都独立隔离：同步抛出或返回的 promise 被拒绝时，只会记录日志，不会阻塞同级监听器或改变运行。
 
 提供方新增和移除还会发出 `subagent/provider-added` 与 `subagent/provider-removed`。面向模型的工具等消费方使用这些事件，因为 Cordis 可能并发加载同级插件；配置顺序不能证明注册顺序。

 The optional, globally named `send_message` tool: a thin adapter over `ctx.subagents.followup()`. Provider-bound `@deepseek-ai/dsh-tool-subagent` instances register distinct delegation tools per transport; this separately loaded package registers one shared follow-up tool, so multiple delegation tools never register duplicate global controls. Its presence does not determine whether a delegation tool starts continuable work.
 
-The tool performs no lifecycle routing. It attributes every follow-up as `{ kind: 'coordinator', senderSessionId: parent.id }`; the subagent service preserves that source while deciding between live delivery to the running activation's existing Task and a fresh Task that cold-resumes the durable child. The tool forwards its execution signal, so cancellation while live delivery awaits admission cancels the shared activation and settles only after the child reaches quiescence. The tool renders which route was taken and the relevant Task id. A delivery failure becomes an errored tool result stating the message was not delivered.
+The tool performs no lifecycle routing — residency and cold resume belong to the subagent service. It supplies exact live parent authority (`{ kind: 'parent', agent }`) from `exec.agent` and attributes every message as durable provenance `{ kind: 'coordinator', senderSessionId: parent.id }`, which the service retains but never treats as authority. Every message becomes the subagent's next FIFO turn through `Agent.followup()`: if the child is still working, the message waits until its current turn finishes, so it cannot redirect work already underway. The tool forwards its execution signal, which owns admission only until inbox acceptance; once the child accepts the message the accepted turn cannot be cancelled through this tool. The child does not reply to the sender — its transcript by that id is the source of what it did. A delivery failure becomes an errored tool result stating the message was not delivered.

-- **A delivered message has no independent result** — its effect is reflected in the current Task's eventual result; only a started follow-up owns a fresh Task result.
-- **Delivery can lose timing races** — a message racing task settlement, cancellation, or cleanup fails explicitly rather than falling through to cold resume; the model retries after the task settles.
+- **A queued message has no independent result** — acceptance returns only its inbox `messageId`; the child's work on that turn lands in the durable child Session, read by its subagent id, and is neither delivered back nor collected through this tool.
+- **No steering of the current turn** — every message opens a later FIFO turn, so a message sent while the child is working runs only after its current turn finishes and cannot redirect it.

Subject: [PATCH 370/557] test(subagent): close continuable coverage and drop
 unreachable guards

Restores the one-shot settleRun coverage in its own file beside the helper,
covers fork's seed contribution, the post-transfer rollback, the descriptor
model route on cold resume, manager-unload drain, and a failing teardown branch.

Removes three redundant checks the surrounding contracts already own: the
duplicate-Activation and live-id pre-checks (AgentRegistry.enter is the
authoritative collision boundary) and a rollback lifecycle edge that could never
publish because the epoch had no start edge.

 subagent seam：一个 agent（智能体）将工作委派给子 agent。与 [bash](bash.md) 一样，它是**一项可选能力**，不属于 agent loop（智能体循环）主干，因此其词汇定义在此而非 [core.md](core.md) 中。但它在一个维度上与其他所有 seam 不同：**同一上下文中可共存多个提供方实现**，按名称注册（`ctx.subagents`），而 bash 只允许一个执行器。注册表的形状参照 [LLM（大语言模型）适配器注册表](llm-streaming.md)，而非单服务的 bash 执行器。

+## 可继续子 agent 与激活
+
+**可继续后台 subagent** 是一份持久化子 agent 会话（Session），至多关联一个进程内的 **Activation（激活）**——即被重建的子 Agent 的一段驻留纪元（residency epoch）。Activation 不是请求、结果、取消或 Task 边界：它可以执行多个 FIFO 轮次，并在其创建的后代仍在运行期间保持驻留。继续执行管理器负责 activation 准入、授权、实时所有权图、冷恢复（cold resume）与子级优先释放；agent loop 负责一切轮次排序与执行。任何可继续路径都不会创建 Task，也不会创建承载中间结果的包装层。
+
+```text
+persisted Session
+  -> optional live Activation
+       -> one retained AgentHandle
+       -> Agent inbox as the only turn FIFO
+       -> zero or more owned child Activations
 ```
 
-## 可继续子 agent 与提供方恢复
+`SubagentService.startContinuable()` 会预留稳定的子 agent id，对版本化的 `subagent/descriptor` payload 建立快照，向指定提供方索取其分离的 `ContinuableCreateSpec`，通过私有的 activation-owner 作用域创建子 Agent，建立任何可继续父级的所有权，并提交初始 prompt。当收件箱（inbox）准入产出消息 id 时，它以 `{ childId, messageId }` resolve——无需等待轮次开始，也无需等待消息进入会话日志。在该准入之前的任何失败都会以两个 id 都不返回的方式 reject，并 dispose 任何已创建的 handle，回滚 Activation 与父级所有权。
 
-**可继续后台 subagent** 是一份持久化子 agent 会话，由一系列由 Task 支撑的激活组成。`SubagentService.startContinuable()` 会分配稳定的子 agent id、对版本化的 `subagent/descriptor` payload 建立快照，并通过面向提供方的启动请求传入二者；提供方会准确发布该 id，并在初始 prompt 获准前追加描述符。`SubagentService.followup()` 沿用 `Agent` 的意图动词：它会引导实时激活，或在加载并授权已停止的子 agent 后，仅在内部向提供方分发已解析的恢复请求。只有 `ctx.tasks` 和 `ctx.agents` 存在时，内部管理器才会负责描述符查找与 Task 关联；每项继续执行操作都要求持久化，而加载提供方注册表不要求持久化。`startContinuable()` 返回两个标识，`followup()` 则报告内容是对现有 Task 执行了 `steered`，还是 `started` 一个新 Task。每个发送方都通过一个选项对象提供 `MessageSource` 和取消信号；若在在线投递等待准入期间中止该信号，则会取消共享激活，并在其完全停稳后拒绝调用。可选的面向模型工具使用 `CoordinatorMessageSource` 及其工具执行信号，人工适配器则使用 `{ kind: 'user' }` 及其交互信号。
+`SubagentService.followup()` 是唯一的继续执行消息操作，其路由仅取决于 Activation 的驻留状态：
+
+| Activation 状态 | 发送方 | `followup` |
+|---|---|---|
+| `running` | parent 或 user | 在同一 Activation 中入队 |
+| `waiting` | parent 或 user | 唤醒同一 Activation |
+| 无 Activation | parent 或 user | 冷恢复一个新的 Activation |
+
+`running` 表示 Agent 拥有活跃的准入或轮次，或正在唤醒收件箱工作；`waiting` 表示它已停稳，但仍拥有至少一个尚未完成 dispose 的子 Activation；`settled` 表示已停稳且其拥有的每个子级都已 dispose，此时管理器会 dispose `AgentHandle` 并移除该 Activation。管理器根据 Agent 的完全停稳状态与其拥有的子级集合推导这些状态，而非维护第二套执行状态机；`activationState()` 报告当前值（无存活 Activation 时为 `undefined`）。
+
+Agent 收件箱是唯一的队列。每条继续执行消息都会成为一个 `Agent.followup()` FIFO 轮次，因此 parent 与 user 消息共享同一个可观测顺序，且后续消息无法改变已在进行中的轮次。投递成功会返回被接受的 `MessageId`；既有的 `agent/inbox/enqueue`、`agent/inbox/dequeue` 与 `agent/inbox/discard` 事件仍是消息生命周期的观测点，继续执行层不定义任何 subagent 专属的投递路由。
+
+授权由受信任的宿主交互或一个确切的实时 Agent 工具上下文提供。仅当已认证的 Agent 是持久化子 agent 在 `SessionHeader.parentSession` 中记录的直接父级时，才会准入 parent 变体；只有受信任的宿主适配器才能提供 user 授权。`MessageSource` 与 `senderSessionId` 在准入之后是持久的来源凭据，不授予任何权限——可选的面向模型工具使用 `CoordinatorMessageSource`，宿主适配器则使用 `{ kind: 'user' }`。user 授权可以在不加载子 agent 历史父级的情况下冷恢复它。
+
+对于这两种操作，调用方 signal 仅在收件箱接受之前掌管查找、物化与准入。此后管理器独立掌管该 Activation：之后的调用方取消既不会取消已接受的轮次，也不会 dispose 子 agent，并且该 seam 不对外暴露任何 subagent 取消或 steering（中途引导）操作。
+
+每个 Activation 都拥有自己的 `AgentHandle` 和一个 `ownedChildren: Set`；由于一份会话至多有一个存活 Activation，子会话 id 无需另一个运行时化身引用即可标识存活的子 agent。启动子 agent 或提交源自 parent 的工作，会在子 agent 能够运行之前将其注册到受继续执行管理的父级集合中；只要该集合非空，该父级就无法 settle。顶层或其他非继续执行的 Agent 没有 Activation，处于 waiting 图之外。只有当子 Agent 已停稳、该子 agent 的每个子级都已 dispose、最终的持久性检查点结算完毕，且子 agent 的 `AgentHandle` 完成 dispose 之后，才会释放子 agent。
+
+只有 `ctx.sessions.flush(session) === true` 才确认持久性；`false` 或 rejection 会报告 `DURABILITY_FAILED`。无论哪种情况，管理器仍会 dispose 该 handle 并释放所有权，因为保留一个失败的子 agent 会将其祖先永久钉在 `waiting`——此后持久化的子 agent 状态在后续恢复时可能缺失或陈旧。`drainContinuable()` 是覆盖整个生命周期的停止路径：它同步关闭准入，随后以子级优先的方式 dispose 每一片存活的 Activation 森林，尽管个别分支失败仍会等待每个分支。持久化子会话不受该进程内拆卸的影响。

Subject: [PATCH 371/557] test(subagent): reach full continuable coverage and
 simplify unreachable paths

Adds coverage for the fork-seeded descriptor turn numbering, omitted and declared
descriptor composition fields, a routeless cold resume, and the drain no-op.

Splits materialize's create-versus-resume inputs so the impossible
create-without-meta case disappears, drops the observer's unreachable
pre-residency guard, and annotates the three remaining paths that only a
non-deterministic send-versus-dispose race can reach.

Subject: [PATCH 372/557] fix(acp): drain continuable subagents before
 disposing top-level agents

A continuable Activation outlives the turn that started it and owns descendant
teardown, so the bridge must drain that forest child-first before releasing the
top-level agents whose runtime the descendants depend on.

Also rewrites the authored continuable snapshot transcript for the Task-free
tool surface; the scenario's keyless replay is still under diagnosis.

Subject: [PATCH 373/557] test(acp-agent): rewrite the continuable snapshot for
 the Task-free surface

The authored transcript drove task_output, which no longer exists for a
continuable child and is not registered in this config, so the scenario hung.
It now demonstrates the RFC criteria directly: a delegation returning only the
durable subagent id, two send_message follow-ups queueing as later FIFO turns on
one inbox, an unknown id failing without delivery, and child-first disposal
despite a failed final durability checkpoint.

The snapshot-only overlay remaps the transcript's placeholder child id onto the
randomly minted live child, since the scripted model cannot know that id.

Also drops probe logging accidentally committed in cf0138258.

Subject: [PATCH 374/557] test(acp-agent): refresh header pins for the new
 subagent tool wording

Every scenario compares its live tool schemas and system prompt against the
shared header pins, so the Task-free subagent and send_message descriptions
change all 14 pin sidecars. The diff is only that wording plus the tools'
output-type shapes.

Subject: [PATCH 375/557] test(acp): cover the continuable drain ordering and
 its failure path

Pins that the bridge releases the Activation forest before its own sessions, and
that a failed drain is reported without stranding that teardown. Reads the one
teardown method structurally so the bridge keeps no dependency on the subagent
seam.

Subject: [PATCH 377/557] fix(subagent): address codex review round 1

All five findings were real:

- The terminal lifecycle edge derived its stop reason from teardown success, so a
  child that errored, hit its token ceiling, or was cancelled reported as
  completed once its checkpoint and disposal succeeded. It now reads the child's
  own last message turn/end, which is authoritative.
- Live delivery never rechecked the caller signal after authorization yielded, so
  an abort that won before acceptance still enqueued the message and returned an
  id. Admission now re-checks at the boundary that owns the decision.
- Drain flushed before cancelling, letting a running turn keep appending events
  the checkpoint could not cover and letting model work continue through a slow
  flush. It now cancels to quiescence first.
- subagent/end fired after AgentHandle.dispose() unregistered the child, so the
  hooks bridge could not resolve it for the child's cwd and scope. The edge now
  publishes while the child is still registered.
- activationState() read Agent.status alone, which stays idle between an accepted
  waking send and the microtask that admits it, so a synchronous inbox observer
  could see settled with a queued turn. Residency now also counts messages this
  manager admitted but has not seen leave the inbox.

Subject: [PATCH 378/557] fix(subagent): address codex review round 2

Round 1 traded one teardown ordering problem for another. The observer now
splits capture from emission, which satisfies both consumers at once:

- Terminal facts are captured while the child is still registered, so consumers
  that resolve it for the child's log and scope still work.
- The edge is emitted only after handle disposal settles, so a rejecting scoped
  cleanup is reported as a failed epoch instead of a successful one.

Also:

- Keep the Activation in the map until disposal settles. Removing it first let a
  racing followup() see no Activation and cold-resume into the still-registered
  agent, and let a concurrent forest drain skip a still-disposing child and
  release its parent first.
- Derive terminal telemetry from this epoch's event suffix rather than the whole
  session, so a cold resume whose prompt is blocked no longer reports the
  previous epoch's answer and turn reason.
- Cancel the ACP bridge's own prompts before awaiting the descendant drain: a
  drain can block on persistence, and the top-level agents must not keep running
  model and tool work for its whole duration.

Subject: [PATCH 379/557] fix(subagent): address codex review round 3
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Make host-user authority unforgeable. `{ kind: 'user' }` was a bare
  discriminant, so any plugin holding `ctx.subagents` — including
  model-generated cordis_mount code, which the advanced ACP composition ships
  alongside continuable subagents — could construct it and skip the
  direct-parent check for any known child id. It now carries an opaque grant
  that only SubagentService.userAuthority() mints, which composition hands to
  trusted host adapters; a model-facing tool uses parent authority from its own
  execution context.
- Reconcile a delivery discarded inside its own admission window. An enqueue
  listener that cancels fires the discard before followup() returns, so the
  discard listener could not clear an id it had not seen; submit() retained it
  and residency stayed `running` until an explicit drain.
- Recheck the caller signal after materialization. An abort landing between
  publication and inbox acceptance still submitted the prompt and returned both
  ids; it now rolls the child back.
- Stop promising the model transcript access that no shipped continuable config
  mounts. The tools now state only that a background child does not report back.
- Restate the implemented note as shipped state rather than a proposal, so it
  works as current authority.

 ## Problem
 
-The continuation manager currently makes one Task, one provider execution, and one result boundary the same object lifetime. Task settlement disposes the child Agent, Task completion injects the completion notice, and later input reconstructs another Agent. This couples a generic background-work abstraction to conversation delivery even though a continuable subagent already has a Session and an Agent inbox.

Task settlement disposed the child Agent, Task completion injected the completion notice, and later input reconstructed another Agent. That coupled a generic background-work abstraction to conversation delivery even though a continuable subagent already has a Session and an Agent inbox.
 
-Giving queued parent requests to the continuation manager and user messages to the Agent creates two FIFOs with no single ordering authority. Giving both to Tasks instead duplicates the Agent loop's admission, cancellation, and quiescence machinery. `Agent.whenIdle()` cannot recover a per-request Task result because one running interval may drain multiple queued turns, and broad `Agent.cancel()` cannot remove one queued request exactly.

 The runtime lifetime is also wider than one turn. A subagent can finish its own turn while a child it created is still running. Disposing the parent runtime at that point removes the Agent that still owns descendant teardown. Keeping every historical subagent resident instead would make memory use unbounded.

 Top-level teardown is host-owned rather than represented as another Activation. The host first asks the manager to enter draining synchronously, which rejects new creation, resume, and delivery admission, then disposes every live Activation forest in child-first order and awaits all `AgentHandle.dispose()` calls. Only after that drain settles may the host dispose top-level Agents and the manager scope. Manager unload uses the same drain and includes user-resumed Activations without live owners.

+This version exposes no `report` tool and provides no child-to-parent content delivery or automatic parent wakeup. The durable child Session remains the source of the child's detailed output.
 
 A later proposal may add an ordinary model-facing `report(output)` tool that can be called zero or multiple times in one turn. Its delivery policy may distinguish quiet parent injection from waking the parent; recipient selection, acknowledgement, durability, and retry semantics are deferred with that tool. Adding report delivery does not require another Activation state or execution queue.
 
 ### Deferred steering
 
-The MVP exposes no subagent steering operation. Parent and user continuation messages always open later FIFO turns, so the continuation layer stores no current-turn controller and adds no controller-aware Agent admission seam.

 A later host UI may expose separate **Steer** and **Follow up** actions. User steering would be strict and live-only: it may call the existing Agent steering path only while the Activation accepts a next step, must reject otherwise, and must never fall back to queueing or cold resume. Exposing parent steering to a model-facing tool remains a separate design because distinct tool names express intent but do not establish whether the parent may modify a user-controlled turn.

 User authority may cold-resume a child without its parent. Parent-originated delivery requires the parent to be live when admitted and keeps it live through the ownership relationship.

The caller signal can abort start or follow-up only before inbox acceptance. After acceptance, neither parent nor user can cancel the message, turn, or Activation through `ctx.subagents`; `Agent.cancel()` remains a lower-level Agent capability that this MVP does not expose through the subagent service.

 The Agent inbox is the only queue. Every continuation message becomes one `Agent.followup()` FIFO turn, so parent and user messages share one observable order and a follow-up cannot redirect a turn already underway. Successful delivery returns the accepted `MessageId`; the existing `agent/inbox/enqueue`, `agent/inbox/dequeue`, and `agent/inbox/discard` events remain the message-lifecycle observations, and the continuation layer defines no subagent-specific delivery route.

+Authority is supplied by a trusted host interaction or an exact live Agent tool context. The parent variant is admitted only when the authenticated Agent is the durable child's direct parent recorded in `SessionHeader.parentSession`. User authority carries an opaque grant that only `SubagentService.userAuthority()` mints, so a caller cannot claim it by writing the discriminant — a plugin holding `ctx.subagents`, including model-generated mount code, would otherwise bypass the direct-parent check for any known child id. `MessageSource` and `senderSessionId` are durable provenance after admission and grant no authority — the optional model-facing tool uses `CoordinatorMessageSource`, while a host adapter uses `{ kind: 'user' }`. User authority may cold-resume a child without loading its historical parent.
 
 For both operations the caller signal owns lookup, materialization, and admission only until inbox acceptance. Afterwards the manager owns the Activation independently: later caller cancellation neither cancels the accepted turn nor disposes the child, and the seam exposes no public subagent cancellation or steering operation.

 | `start(name, request)` | Validate an ordinary caller request, then await the provider until a real one-shot child is ready. Fulfillment returns a holder-owned `SubagentRun`; rejection means the provider has already cleaned every partial startup resource. Continuable children never enter through this operation. |
 | `startContinuable(spec)` | Establish one durable continuable child and deliver its initial prompt. Resolves with `{ childId, messageId }` when the child's inbox accepts that prompt, without waiting for the turn to start or for the message to reach the Session log; any earlier failure rejects with no ids and rolls the child back entirely. Requires `ctx.agents`, session persistence, and a provider with the `prepareContinuable` capability. |
 | `followup(authority, childId, content, { source, signal })` | Deliver one later message to a continuable child as its next FIFO turn, matching `Agent.followup()` terminology, and return the accepted `AgentMessageId`. A resident child's inbox accepts it directly (waking a `waiting` Activation); an absent one cold-resumes from its persisted Session. Requires `ctx.agents`; cold resume also requires session persistence. |
+| `userAuthority()` | Mint the host-user authority a trusted adapter passes to `followup()`. Composition hands this only to a host carrying real human interaction; a model-facing tool uses its own `{ kind: 'parent', agent }` instead. |
 | `activationState(childId)` | Read one durable child's live residency state (`running`, `waiting`, or `settled`), or `undefined` when no Activation is live. |
 | `drainContinuable()` | Close continuable admission synchronously, then dispose every live Activation forest child-first. A host calls this before disposing top-level agents so no descendant outlives the runtime that owns its teardown. An aggregate error surfaces after every branch settles when any failed. |
 
 `SubagentStartRequest.signal` is required and is the canonical cancellation channel for a one-shot `start`. An abort before publication makes `start()` reject after rollback; an abort after publication cancels the live child. The request may also select a model, require structured output, cap delegation depth, restrict child tools, or set a child persona. For a continuable start or follow-up, the caller signal owns lookup, materialization, and admission only until inbox acceptance; afterward the manager owns the Activation independently, so later caller cancellation neither cancels the accepted turn nor disposes the child.
 
-Authority for continuable operations comes from a trusted host interaction or an exact live Agent tool context: `SubagentAuthority` is `{ kind: 'parent', agent }` or `{ kind: 'user' }`. The `source` on a follow-up is durable provenance retained on the delivered message and grants no authority. Parent authority requires the exact live direct parent recorded in the child's durable header; user authority may continue any child, and may cold-resume it without loading its historical parent.
+Authority for continuable operations comes from a trusted host interaction or an exact live Agent tool context: `SubagentAuthority` is `{ kind: 'parent', agent }` or `{ kind: 'user', grant }`, whose grant only `userAuthority()` mints so the discriminant alone cannot claim it. The `source` on a follow-up is durable provenance retained on the delivered message and grants no authority. Parent authority requires the exact live direct parent recorded in the child's durable header; user authority may continue any child, and may cold-resume it without loading its historical parent.
 
 Same-process requests, descriptors, results, and event payloads are trusted typed values borrowed as immutable. The service does not clone or freeze them; serialization and hostile-input validation belong at actual process, worker, persistence, and model boundaries.

 `SubagentStartRequest.signal` 是必填项，也是一次性 `start` 的规范取消通道。发布前中止会使 `start()` 在回滚后拒绝；发布后中止会取消实时子 agent。请求还可以选择模型、要求结构化输出、限制委派深度、约束子 agent 工具或设置子 agent persona。对于可继续启动或后续操作，调用方信号只在 inbox 接受之前掌管查找、物化和准入；此后由管理器独立拥有 Activation，因此调用方后续取消既不会取消已接受的轮次，也不会 dispose 子 agent。

Subject: [PATCH 380/557] refactor(subagent): drop host-user authority and
 split lifecycle publication
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Remove the host-user continuation capability and the public residency query,
then separate the seam's public event payloads from its internal lifecycle
control interfaces.

`followup()` now takes the exact live direct parent `Agent` instead of a
`SubagentAuthority` union. No production adapter ever supplied user authority,
so the `UserAuthorityGrant` brand token existed only to stop a forged
discriminant from bypassing the direct-parent check — deleting the branch
retires the token, its mint method, and that attack surface together.

Narrowing `parent` from `Agent | undefined` to `Agent` removes three special
cases, including the path where a parentless epoch dispatched its lifecycle
events unscoped. Scoped-versus-global dispatch is now decided by the event, not
by whether a caller happened to have a parent.

`activationState()` had no caller; `ActivationState`, `ActivationObserver`, and
`ContinuationHost` are package-private.

New `src/lifecycle.ts` owns the contained emitter, the one-shot run observer,
and the Activation observer, while `SubagentRunInfo`/`SubagentRunEndInfo` move
to `src/types.ts` beside the other consumer-facing contracts. Those payloads are
public API — dsh-jsonrpc, hooks-claude, and the package invariant all consume
them — whereas the observer is a contract between two in-package collaborators,
so they no longer share a home merely for both being lifecycle-shaped. The
service keeps ownership of the scope carrier: `scopeTarget()` composes the
service's own context filter, so a narrowed stand-in would silently change
scope filtering.

Also drops now-unused dsh-tasks-local and dsh-tool-tasks dev dependencies, and
corrects the README claim that a pre-residency failure emits a terminal edge —
that path only ever rethrew.

 The activation-owner scope exists because ordinary Cordis owner effects unwind in reverse registration order, which cannot express the dynamic child graph. Manager initialization registers the private scope's structural disposer first and its drain disposer afterward, so reverse unwind invokes the drain before releasing that scope; merely registering a cleanup effect on the same scope as later Agent handles would allow structural handle disposal to bypass child-first ordering. The manager snapshots the live roots after closing admission, stops its outward lifecycle notifications before cancellation, and retains its internal ownership bookkeeping until every handle settles. Each Activation has one memoized disposal promise so host shutdown, manager unload, child release, and normal settlement can converge without double release. Sibling branches drain independently; one disposal failure is recorded but does not prevent the manager from attempting the remaining handles, and the aggregate drain reports failure after all branches settle. Durable child Sessions survive this process-local teardown.

The parent variant is admitted only when the authenticated Agent is the durable child's direct parent recorded in `SessionHeader.parentSession`. User authority carries an opaque grant that only `SubagentService.userAuthority()` mints, so a caller cannot claim it by writing the discriminant — a plugin holding `ctx.subagents`, including model-generated mount code, would otherwise bypass the direct-parent check for any known child id. `MessageSource` and `senderSessionId` are durable provenance after admission and grant no authority — the optional model-facing tool uses `CoordinatorMessageSource`, while a host adapter uses `{ kind: 'user' }`. User authority may cold-resume a child without loading its historical parent.

The authenticated Agent must be the durable child's direct parent recorded in `SessionHeader.parentSession`. `MessageSource` and `senderSessionId` are durable provenance after admission and grant no authority; the optional model-facing tool uses `CoordinatorMessageSource`.
 
 For both operations the caller signal owns lookup, materialization, and admission only until inbox acceptance. Afterwards the manager owns the Activation independently: later caller cancellation neither cancels the accepted turn nor disposes the child, and the seam exposes no public subagent cancellation or steering operation.

 The provider participates only in preparing the initial creation spec, where `spawn` and `fork` differ. Its returned spec carries only detached provider-specific creation inputs — today the optional parent-history seed — and no Agent, `AgentHandle`, prompt delivery, result, disposal, or resume operation. Cold resume does not dispatch through a provider at all: the manager folds the generic descriptor, calls `ctx.agents.resume()` through the same activation-owner scope, and submits the waiting turn.

 `SubagentStartRequest.signal` is required and is the canonical cancellation channel for a one-shot `start`. An abort before publication makes `start()` reject after rollback; an abort after publication cancels the live child. The request may also select a model, require structured output, cap delegation depth, restrict child tools, or set a child persona. For a continuable start or follow-up, the caller signal owns lookup, materialization, and admission only until inbox acceptance; afterward the manager owns the Activation independently, so later caller cancellation neither cancels the accepted turn nor disposes the child.
 
-Authority for continuable operations comes from a trusted host interaction or an exact live Agent tool context: `SubagentAuthority` is `{ kind: 'parent', agent }` or `{ kind: 'user', grant }`, whose grant only `userAuthority()` mints so the discriminant alone cannot claim it. The `source` on a follow-up is durable provenance retained on the delivered message and grants no authority.

 A continuable child has one durable Session and at most one process-local **Activation** — one residency epoch for a reconstructed child Agent, not a request, result, cancellation, or Task boundary. The Agent inbox is the only turn queue, so the continuation manager owns residency while the Agent loop owns all turn ordering and execution. No continuable path creates a Task or an intermediate result-bearing wrapper.
 
-The public residency state has three values derived from Agent quiescence and the owned-child set, not a second state machine: `running` (an active admission, open turn, or waking inbox work), `waiting` (quiescent but still owning at least one undisposed child), and `settled` (quiescent with every owned child disposed, so the manager disposes the `AgentHandle` and removes the Activation). Every continuation message uses `Agent.followup()` and becomes one FIFO turn, so parent and user messages share one observable order with no steering of the current turn. Routing depends only on residency: `running` enqueues, `waiting` wakes the same Agent, and an absent Activation cold-resumes a new one.
+The manager derives three internal residency conditions from Agent quiescence and the owned-child set rather than maintaining a second state machine: running (an active admission, open turn, or waking inbox work), waiting (quiescent but still owning at least one undisposed child), and settled (quiescent with every owned child disposed, so the manager disposes the `AgentHandle` and removes the Activation). Every continuation message uses `Agent.followup()` and becomes one FIFO turn with no steering of the current turn. Routing depends only on residency: running enqueues, waiting wakes the same Agent, and an absent Activation cold-resumes a new one.
 
-The manager reserves the child identity, resolves the durable descriptor, calls `ctx.agents.create()` (or `ctx.agents.resume()` for cold resume) through a private activation-owner scope, installs the returned `AgentHandle` in the Activation, establishes any continuable-parent ownership, and then submits the prompt. Cold resume never dispatches through a provider — the persisted Session already holds the initial prefix and the folded descriptor is the whole reconstruction input — so a user can cold-resume a persisted child without loading its historical parent.

Cold resume never dispatches through a provider because the persisted Session already holds the initial prefix and the folded descriptor is the whole reconstruction input.
 
 A continuation-managed parent Activation records each child Session id in an `ownedChildren` set before the child can run and disposes only after every owned child Activation completes `AgentHandle` disposal (child-first). Top-level and other non-continuation Agents have no Activation and stay outside this waiting graph. Final settlement treats only `ctx.sessions.flush(child.session) === true` as durability confirmation; `false` or rejection reports `DURABILITY_FAILED` and still disposes the handle and releases ownership, because retaining a failed child would permanently pin its ancestors in `waiting`.
 
 ## Lifecycle events
 
-The service emits a `subagent/start`/`subagent/end` pair for each one-shot run and each continuable Activation's residency epoch, so continuable children are observable with the same vocabulary as one-shot runs without exposing whether the manager materialized, woke, or cold-resumed them. For a one-shot start it attaches the result observer before the synchronous `subagent/start`, so even an already-settled child still produces `subagent/start` before `subagent/end`; a continuable epoch that never becomes resident emits only the terminal edge, because it has no start edge to pair. The pair shares a service-minted `runId`; the `local` flag is snapshotted from the provider's exact `localAgent` (always true for a continuable child), so observers never infer run identity or locality from reusable provider/session names.

Every listener is independently contained: a synchronous throw or rejected returned promise is logged without starving peer listeners or changing the run.

 - **ACP children remain one-shot** — an ACP `prepareContinuable` requires persisting the remote session id in provider-specific descriptor data and a per-child continuation advertisement, since ACP `loadSession` support is negotiated per child rather than established by the method's presence. Remote providers also require a separate Activation ownership contract with equivalent authenticated control and child-first quiescence before they support continuable children.
 - **No report delivery** — the MVP exposes no `report` tool, child-to-parent content delivery, or automatic parent wakeup; a completed child turn leaves its output in the durable child Session until a caller inspects that transcript or submits another authorized turn.

 可继续子 agent 拥有一个持久化 Session 和至多一个进程内 **Activation**——即被重建的子 agent 的一个驻留时段，而不是请求、结果、取消或 Task 边界。Agent inbox 是唯一的轮次队列，因此继续执行管理器负责驻留，而 Agent 循环负责所有轮次排序与执行。任何可继续路径都不会创建 Task 或中间的承载结果的包装器。

 The named subagent provider participates only in preparing the initial creation spec, where `spawn` and `fork` differ. Its optional `prepareContinuable(request): Promise` method is the continuable-creation capability. The returned spec contains only detached provider-specific creation inputs such as the optional parent-history seed; it contains no Agent, `AgentHandle`, prompt delivery, result, disposal, or resume operation. The manager reserves the child identity, resolves the durable descriptor and common Agent setup, calls `ctx.agents.create()` through a private activation-owner scope, installs the returned `AgentHandle` into the Activation, establishes any continuable-parent ownership, and then calls `Agent.followup(initialPrompt)`. Inbox acceptance yields an `MessageId`; at that boundary `ctx.subagents.startContinuable()` returns `{ childId, messageId }` without waiting for the turn to start or for the message to enter the Session log.
 
-Any failure before inbox acceptance rejects without returning either id. Agent creation provides rollback before handle transfer; after transfer, the manager disposes the created handle, removes the Activation, and rolls back any parent `ownedChildren` membership before rejecting.
+Any failure before inbox acceptance rejects without returning either id. Agent creation provides rollback before handle transfer; after transfer, the manager keeps one closing transaction visible to concurrent delivery and drain, disposes the created handle, removes the Activation, and rolls back any parent `ownedChildren` membership before rejecting. Failure before the residency start edge publishes no terminal edge, while failure after a published start closes the lifecycle pair through normal disposal.
 
 `backgroundMode: 'one-shot' | 'continuable'` remains deployment policy. Configured continuable mode requires `prepareContinuable`; method presence replaces `SubagentProvider.resume?()` as the capability check, while a capable provider may still run one-shot work.

+Top-level teardown is host-owned rather than represented as another Activation. The host first asks the manager to enter draining synchronously, which rejects new creation, resume, and delivery admission, then disposes every live Activation forest in child-first order and awaits all `AgentHandle.dispose()` calls. Every materialized start and live delivery rechecks caller cancellation, draining, and Activation disposal in the same synchronous span as inbox submission, so teardown that begins before acceptance prevents delivery to the closing handle. Only after that drain settles may the host dispose top-level Agents and the manager scope. Manager unload uses the same drain.
 
 The activation-owner scope exists because ordinary Cordis owner effects unwind in reverse registration order, which cannot express the dynamic child graph. Manager initialization registers the private scope's structural disposer first and its drain disposer afterward, so reverse unwind invokes the drain before releasing that scope; merely registering a cleanup effect on the same scope as later Agent handles would allow structural handle disposal to bypass child-first ordering. The manager snapshots the live roots after closing admission, stops its outward lifecycle notifications before cancellation, and retains its internal ownership bookkeeping until every handle settles. Each Activation has one memoized disposal promise so host shutdown, manager unload, child release, and normal settlement can converge without double release. Sibling branches drain independently; one disposal failure is recorded but does not prevent the manager from attempting the remaining handles, and the aggregate drain reports failure after all branches settle. Durable child Sessions survive this process-local teardown.

 activation-owner 作用域之所以存在，是因为普通 Cordis owner effect 按注册逆序撤销，无法表达动态 child 图。管理器初始化时先注册私有作用域的结构化 disposer，再注册自身的 drain disposer，使逆序撤销先执行 drain、再释放该作用域；如果只在与后续 Agent handle 相同的作用域上注册 cleanup effect，结构化 handle dispose 就可能绕过 child-first 顺序。管理器在关闭准入后对在线根节点创建快照，在取消前停止自身的对外生命周期通知，并保留内部所有权簿记，直至每个 handle 都结算。每次激活有一个记忆化的 dispose promise，使宿主关闭、管理器卸载、child 释放和正常结算能够汇合，而不会重复释放。同级分支独立 drain；系统会记录单次 dispose 失败，但仍会尝试其余 handle，聚合 drain 则在所有分支结算后报告失败。这次进程内拆卸不会销毁持久化 child 会话。

-The service emits a `subagent/start`/`subagent/end` pair for each one-shot run and each resident continuable Activation epoch, so continuable children are observable with the same vocabulary as one-shot runs without exposing whether the manager materialized, woke, or cold-resumed them. For a one-shot start it attaches the result observer before the synchronous `subagent/start`, so even an already-settled child still produces `subagent/start` before `subagent/end`; a continuable epoch that fails before residency emits neither edge. The pair shares a service-minted `runId`; the `local` flag is snapshotted from the provider's exact `localAgent` (always true for a continuable child), so observers never infer run identity or locality from reusable provider/session names.

The `provider` field is lifecycle provenance rather than a live-registry claim: an accepted one-shot run may become ready after provider removal, and a cold-resumed epoch retains its descriptor's initial provider name without requiring that provider to be registered.
 
 Run events are scoped to the delegating parent. Every listener is independently contained: a synchronous throw or rejected returned promise is logged without starving peer listeners or changing the run.

 The optional, globally named `send_message` tool: a thin adapter over `ctx.subagents.followup()`. Provider-bound `@deepseek-ai/dsh-tool-subagent` instances register distinct delegation tools per transport; this separately loaded package registers one shared follow-up tool, so multiple delegation tools never register duplicate global controls. Its presence does not determine whether a delegation tool starts continuable work.
 
-The tool performs no lifecycle routing — residency and cold resume belong to the subagent service. It supplies exact live parent authority (`{ kind: 'parent', agent }`) from `exec.agent` and attributes every message as durable provenance `{ kind: 'coordinator', senderSessionId: parent.id }`, which the service retains but never treats as authority. Every message becomes the subagent's next FIFO turn through `Agent.followup()`: if the child is still working, the message waits until its current turn finishes, so it cannot redirect work already underway. The tool forwards its execution signal, which owns admission only until inbox acceptance; once the child accepts the message the accepted turn cannot be cancelled through this tool. The child does not reply to the sender — its transcript by that id is the source of what it did. A delivery failure becomes an errored tool result stating the message was not delivered.

+Top-level teardown is host-owned rather than represented as another Activation. The host first asks the manager to enter draining synchronously, which rejects new creation, resume, and delivery admission. The manager then awaits every materialization that already passed admission until it either installs a resident Activation or completes rollback, snapshots the stable live forest, disposes it child-first, and awaits all `AgentHandle.dispose()` calls. Every materialized start and live delivery rechecks caller cancellation, draining, Activation disposal, and exact parent authority in the same synchronous span as inbox submission, so teardown or parent replacement that wins before acceptance prevents delivery to the closing handle. Only after that drain settles may the host dispose top-level Agents and the manager scope. Manager unload uses the same drain.
 
 The activation-owner scope exists because ordinary Cordis owner effects unwind in reverse registration order, which cannot express the dynamic child graph. Manager initialization registers the private scope's structural disposer first and its drain disposer afterward, so reverse unwind invokes the drain before releasing that scope; merely registering a cleanup effect on the same scope as later Agent handles would allow structural handle disposal to bypass child-first ordering. The manager snapshots the live roots after closing admission, stops its outward lifecycle notifications before cancellation, and retains its internal ownership bookkeeping until every handle settles. Each Activation has one memoized disposal promise so host shutdown, manager unload, child release, and normal settlement can converge without double release. Sibling branches drain independently; one disposal failure is recorded but does not prevent the manager from attempting the remaining handles, and the aggregate drain reports failure after all branches settle. Durable child Sessions survive this process-local teardown.

 `SubagentStartRequest.signal` is required and is the canonical cancellation channel for a one-shot `start`. An abort before publication makes `start()` reject after rollback; an abort after publication cancels the live child. The request may also select a model, require structured output, cap delegation depth, restrict child tools, or set a child persona. For a continuable start or follow-up, the caller signal owns lookup, materialization, and admission only until inbox acceptance; afterward the manager owns the Activation independently, so later caller cancellation neither cancels the accepted turn nor disposes the child.

-Top-level teardown is host-owned rather than represented as another Activation. The host first asks the manager to enter draining synchronously, which rejects new creation, resume, and delivery admission. The manager then awaits every materialization that already passed admission until it either installs a resident Activation or completes rollback, snapshots the stable live forest, disposes it child-first, and awaits all `AgentHandle.dispose()` calls. Every materialized start and live delivery rechecks caller cancellation, draining, Activation disposal, and exact parent authority in the same synchronous span as inbox submission, so teardown or parent replacement that wins before acceptance prevents delivery to the closing handle. Only after that drain settles may the host dispose top-level Agents and the manager scope. Manager unload uses the same drain.
+Top-level teardown is host-owned rather than represented as another Activation. Manager unload uses `drainContinuable()` to close manager-wide admission synchronously, await every admitted materialization through publication or rollback, stop the stable live forest, and release it child-first. A host that owns selected top-level Agents instead uses `drainContinuableDescendants(parents)`: exact Agent identities close admission only below those roots until each leaves the registry, while unrelated forests and manager-wide admission remain live; the manager stops their visible descendants before its first await, waits only materializations admitted below those roots, and releases only the selected branches. Every materialized start and live delivery rechecks caller cancellation, the applicable draining scope, Activation disposal, and exact parent authority in the same synchronous span as inbox submission, so teardown or parent replacement that wins before acceptance prevents delivery to the closing handle. Only after the applicable drain settles may the host dispose its top-level Agents; only the global drain precedes manager-scope disposal.
 
-The activation-owner scope exists because ordinary Cordis owner effects unwind in reverse registration order, which cannot express the dynamic child graph. Manager initialization registers the private scope's structural disposer first and its drain disposer afterward, so reverse unwind invokes the drain before releasing that scope; merely registering a cleanup effect on the same scope as later Agent handles would allow structural handle disposal to bypass child-first ordering. The manager snapshots the live roots after closing admission, stops its outward lifecycle notifications before cancellation, and retains its internal ownership bookkeeping until every handle settles. Each Activation has one memoized disposal promise so host shutdown, manager unload, child release, and normal settlement can converge without double release. Sibling branches drain independently; one disposal failure is recorded but does not prevent the manager from attempting the remaining handles, and the aggregate drain reports failure after all branches settle. Durable child Sessions survive this process-local teardown.

Each materialization registers its barrier participant and snapshots its exact live ancestry before starting the inner transaction, then remains tracked until it installs an Activation or fully rolls back. The Activation retains weak membership of that ancestry, so an intermediate Agent may leave the registry without hiding a still-live descendant from its host root. Each Activation installs one memoized disposal promise before cancellation or recursive callbacks, allowing scoped host shutdown, global manager unload, child release, and normal settlement to converge without double release. Cancellation propagates top-down before slow descendant cleanup; handle release remains child-first.

 Without Tasks there is no `task_output`, `task_kill`, Task status, per-message result promise, or public subagent cancellation operation. The caller signal can abort start or follow-up only before inbox acceptance.

-Host and manager teardown remains the lifecycle-wide stop path. It closes admission, disposes every live Activation forest child-first, and preserves the durable Sessions.
+Host and manager teardown remains the lifecycle stop path. Manager unload applies it globally; a host applies it only below the exact top-level Agents it owns. Each form closes the applicable admission scope, stops the selected visible Activations, awaits admitted materializations in that scope, releases child-first, and preserves the durable Sessions.
 
 Each turn requests the Session durability checkpoint, and final Activation settlement requires the manager to inspect `ctx.sessions.flush()` rather than ignore its boolean result. `true` confirms that at least one durability listener participated and every listener settled successfully. `false` or rejection reports `DURABILITY_FAILED`; normal background settlement logs the lifecycle failure, while an explicit host or manager drain includes it in the aggregate rejection after all branches settle. Either way, the manager still disposes the handle and releases ownership, and the persisted child state may be missing or stale on a later resume.
 
@@ -188,17 +188,17 @@ The implementation pins these behaviors:
 - `followup()` accepts only the exact live direct parent and rechecks that identity at the final no-await inbox-admission boundary after any materialization; durable message provenance cannot authorize delivery.
 - Continuation messages always use `Agent.followup()` and share its inbox FIFO, including when the child already has an open turn.
 - `ctx.subagents.followup()` and its `send_message` adapter return only the accepted `MessageId`; the continuation layer accepts no delivery target and defines no subagent-specific route result.

+- This version exposes no public subagent cancellation operation; caller signals stop start and follow-up only before inbox acceptance, while host-scoped and manager-global teardown retain child-first cleanup.
 - This version exposes no subagent steering operation or current-turn controller state.
 - An idle Agent with live owned children yields a `waiting` Activation whose `AgentHandle` remains retained.
 - A `next-turn` delivered to `waiting` wakes the same Activation; delivery after completed disposal cold-resumes a new Activation.
 - Every continuation-managed parent Activation disposes only after all directly owned child Activations complete `AgentHandle` disposal; top-level Agents do not join the waiting graph.
 - Final Activation settlement treats only `ctx.sessions.flush(child.session) === true` as durability confirmation; `false` and rejection report `DURABILITY_FAILED`, still dispose the child handle, and still release parent ownership so durability failure cannot leak a `waiting` Activation.
-- Host and manager teardown synchronously enter draining, reject new materialization and delivery, await every admitted materialization through publication or rollback, stop manager-owned outward notifications, dispose the stable live Activation forest child-first, await every branch despite individual failures, and only then dispose top-level Agents and the manager scope; a private activation-owner scope preserves this order against Cordis effect unwinding, and one memoized disposal promise per Activation makes concurrent normal settlement idempotent.
+- Manager teardown closes admission globally; a host owning selected top-level Agents instead closes admission only below their exact identities until those roots leave the registry. Both track admitted materializations by exact ancestry, install one memoized disposal cutoff per selected visible Activation, propagate cancellation top-down, release handles child-first, await every selected branch despite individual failures, and only then dispose the corresponding top-level Agents or manager scope.
 - This version exposes no `report` tool, child-to-parent content delivery, or automatic parent wakeup.
 - Session logs reconstruct only messages that were actually written, with their admitted provenance; inbox-accepted but unlogged messages have no restart guarantee.
 - No continuable-subagent path creates or depends on a Task, `TaskId`, Task completion notice, Task cancellation, or intermediate result-bearing execution wrapper.

 Every Activation owns its `AgentHandle` and an `ownedChildren: Set`; because one Session has at most one live Activation, the child Session id identifies the live child without another runtime-incarnation reference. Starting a child or submitting parent-originated work registers the child in a continuation-managed parent's set before the child can run, and that parent cannot settle while the set is non-empty. A top-level or other non-continuation Agent has no Activation and stays outside the waiting graph. Child release happens only after the child Agent is quiescent, every child of that child is disposed, the final durability checkpoint settles, and the child's `AgentHandle` completes disposal.

 | `startContinuable(spec)` | Establish one durable continuable child and deliver its initial prompt. Resolves with `{ childId, messageId }` when the child's inbox accepts that prompt, without waiting for the turn to start or for the message to reach the Session log; any earlier failure rejects with no ids and rolls the child back entirely. Requires `ctx.agents`, session persistence, and a provider with the `prepareContinuable` capability. |
 | `followup(parent, childId, content, { source, signal })` | Deliver one later message from the exact live direct parent as the child's next FIFO turn, matching `Agent.followup()` terminology, and return the accepted `MessageId`. A resident child's inbox accepts it directly (waking a waiting Activation); an absent one cold-resumes from its persisted Session. Requires `ctx.agents`; cold resume also requires session persistence. |
 | `drainContinuable()` | Close continuable admission synchronously, await every materialization that already passed admission through publication or rollback, then dispose the stable live Activation forest child-first. A host calls this before disposing top-level agents so no descendant outlives the runtime that owns its teardown. An aggregate error surfaces after every branch settles when any failed. |
+| `drainContinuableDescendants(parents)` | Close admission below exact live host-owned parent Agents, stop only their visible continuable descendants, await materializations admitted below those roots through publication or rollback, then release the selected forests child-first. The cutoff lasts until each exact parent leaves the registry; unrelated parent forests and manager-wide admission remain live. |
 
 `SubagentStartRequest.signal` is required and is the canonical cancellation channel for a one-shot `start`. An abort before publication makes `start()` reject after rollback; an abort after publication cancels the live child. The request may also select a model, require structured output, cap delegation depth, restrict child tools, or set a child persona. For a continuable start or follow-up, the caller signal owns lookup, materialization, and admission only until inbox acceptance; afterward the manager owns the Activation independently, so later caller cancellation neither cancels the accepted turn nor disposes the child.

 The manager reserves the child identity, resolves the durable descriptor, calls `ctx.agents.create()` (or `ctx.agents.resume()` for cold resume) through a private activation-owner scope, installs the returned `AgentHandle` in the Activation, establishes any continuable-parent ownership, and then submits the prompt. Cold resume never dispatches through a provider because the persisted Session already holds the initial prefix and the folded descriptor is the whole reconstruction input.
 
-A continuation-managed parent Activation records each child Session id in an `ownedChildren` set before the child can run and disposes only after every owned child Activation completes `AgentHandle` disposal (child-first). Top-level and other non-continuation Agents have no Activation and stay outside this waiting graph. Final settlement treats only `ctx.sessions.flush(child.session) === true` as durability confirmation; `false` or rejection reports `DURABILITY_FAILED` and still disposes the handle and releases ownership, because retaining a failed child would permanently pin its ancestors in `waiting`.

-Top-level teardown is host-owned rather than represented as another Activation.

Every materialized start and live delivery rechecks caller cancellation, the applicable draining scope, Activation disposal, and exact parent authority in the same synchronous span as inbox submission, so teardown or parent replacement that wins before acceptance prevents delivery to the closing handle.

+Top-level teardown is host-owned rather than represented as another Activation. Manager unload invokes its internal manager-wide drain to close admission synchronously, await every admitted materialization through publication or rollback, stop the stable live forest, and release it child-first. A host that owns selected top-level Agents uses `drainContinuableDescendants(parents)`: exact Agent identities close admission only below those roots until each leaves the registry, while unrelated forests and manager-wide admission remain live; the manager stops their visible descendants before its first await, waits only materializations admitted below those roots, and releases only the selected branches. Every materialized start and live delivery rechecks caller cancellation, the applicable draining scope, Activation disposal, and exact parent authority in the same synchronous span as inbox submission, so teardown or parent replacement that wins before acceptance prevents delivery to the closing handle. Only after the applicable drain settles may the host dispose its top-level Agents; only manager-wide drain precedes manager-scope disposal.
 
 The activation-owner scope exists because ordinary Cordis owner effects unwind in reverse registration order, which cannot express the dynamic child graph. Manager initialization registers the private scope's structural disposer first and its drain disposer afterward, so reverse unwind invokes the drain before releasing that scope; merely registering a cleanup effect on the same scope as later Agent handles would allow structural handle disposal to bypass child-first ordering. Each materialization registers its barrier participant and snapshots its exact live ancestry before starting the inner transaction, then remains tracked until it installs an Activation or fully rolls back. The Activation retains weak membership of that ancestry, so an intermediate Agent may leave the registry without hiding a still-live descendant from its host root. Each Activation installs one memoized disposal promise before cancellation or recursive callbacks, allowing scoped host shutdown, global manager unload, child release, and normal settlement to converge without double release. Cancellation propagates top-down before slow descendant cleanup; handle release remains child-first. Sibling branches drain independently; one disposal failure is recorded but does not prevent the manager from attempting the remaining selected handles, and the aggregate drain reports failure after all selected branches settle. Durable child Sessions survive this process-local teardown.

 activation-owner 作用域之所以存在，是因为普通 Cordis owner effect 按注册逆序撤销，无法表达动态 child 图。管理器初始化时先注册私有作用域的结构化 disposer，再注册自身的 drain disposer，使逆序撤销先执行 drain、再释放该作用域；如果只在与后续 Agent handle 相同的作用域上注册 cleanup effect，结构化 handle dispose 就可能绕过 child-first 顺序。每个物化过程都会在启动内部事务前注册其屏障参与项，并对其确切的在线祖先建立快照，然后保持跟踪，直到安装 Activation 或完全回滚。Activation 会以弱引用方式记录其属于这组祖先，因此中间 Agent 即使离开注册表，也不会让仍在线的后代脱离宿主根节点的可见范围。每个 Activation 都会在取消或递归回调前安装一个记忆化的 dispose promise，使限定作用域的宿主关闭、全局管理器卸载、child 释放和正常结算能够汇合，而不会重复释放。取消会在等待缓慢的后代清理之前自顶向下传播；handle 释放仍是 child-first。同级分支独立 drain；系统会记录单次 dispose 失败，但仍会尝试其余选中 handle，聚合 drain 则在所有选中分支结算后报告失败。这次进程内拆卸不会销毁持久化 child 会话。

 | `start(name, request)` | Validate an ordinary caller request, then await the provider until a real one-shot child is ready.

 | `startContinuable(spec)` | Establish one durable continuable child and deliver its initial prompt. Resolves with `{ childId, messageId }` when the child's inbox accepts that prompt, without waiting for the turn to start or for the message to reach the Session log; any earlier failure rejects with no ids and rolls the child back entirely. Requires `ctx.agents`, session persistence, and a provider with the `prepareContinuable` capability. |
 | `followup(parent, childId, content, { source, signal })` | Deliver one later message from the exact live direct parent as the child's next FIFO turn, matching `Agent.followup()` terminology, and return the accepted `MessageId`. A resident child's inbox accepts it directly (waking a waiting Activation); an absent one cold-resumes from its persisted Session. Requires `ctx.agents`; cold resume also requires session persistence. |
-| `drainContinuable()` | Close continuable admission synchronously, await every materialization that already passed admission through publication or rollback, then dispose the stable live Activation forest child-first. A host calls this before disposing top-level agents so no descendant outlives the runtime that owns its teardown. An aggregate error surfaces after every branch settles when any failed. |
 | `drainContinuableDescendants(parents)` | Close admission below exact live host-owned parent Agents, stop only their visible continuable descendants, await materializations admitted below those roots through publication or rollback, then release the selected forests child-first. The cutoff lasts until each exact parent leaves the registry; unrelated parent forests and manager-wide admission remain live. |
 
 `SubagentStartRequest.signal` is required and is the canonical cancellation channel for a one-shot `start`. An abort before publication makes `start()` reject after rollback; an abort after publication cancels the live child. The request may also select a model, require structured output, cap delegation depth, restrict child tools, or set a child persona. For a continuable start or follow-up, the caller signal owns lookup, materialization, and admission only until inbox acceptance; afterward the manager owns the Activation independently, so later caller cancellation neither cancels the accepted turn nor disposes the child.

 `SubagentStartRequest.signal` 是必填项，也是一次性 `start` 的规范取消通道。发布前中止会使 `start()` 在回滚后拒绝；发布后中止会取消实时子 agent。请求还可以选择模型、要求结构化输出、限制委派深度、约束子 agent 工具或设置子 agent persona。对于可继续启动或后续操作，调用方信号只在 inbox 接受之前掌管查找、物化和准入；此后由管理器独立拥有 Activation，因此调用方后续取消既不会取消已接受的轮次，也不会 dispose 子 agent。

+# Agent Note: Durable subagent catalog and list_agents
+
+Status: proposed
+
+English | [中文](2026-07-22-durable-subagent-catalog-and-list-agents.zh.md)
+
+## Problem
+
+Continuable background subagents expose a stable child id and persist the reconstruction descriptor in that child's session, so `send_message` can resume a known child without any listing operation. `list_agents` has a different requirement: after parent restart, enumerate only that parent's direct continuable children even when the caller no longer knows their ids. The durable child-handle and activation design is owned by [continuable background subagents](2026-07-21-continuable-background-subagents.md); this note owns enumeration and its model-facing query.
+
+Enumeration must cross-check immutable session lineage, descriptor validity, and process-local activation state without loading or resuming an Agent merely to display it. It must also define how missing, corrupt, deleted, or unsupported children affect the list and whether repeatedly loading many child logs needs an index.
+
+## Proposal
+
+Treat parent-to-child enumeration and `list_agents` as one separately reviewed feature built on the durable child-handle contract. `SubagentControlService.listChildren(parent)` must:
+
+- find materialized session headers whose `parentSession` identifies the caller's session;
+- load and validate each candidate's `subagent/descriptor` event without activating the child;
+- exclude sessions that are one-shot, corrupt, unsupported, missing, or not direct children;
+- overlay the process-local Task association without treating it as durable state.
+
+Descriptor format, persistence, by-id lookup, direct-parent authorization, and cold resume remain owned by the activation proposal. Listing consumes those facts but cannot weaken them or invent a second descriptor representation.
+
+### Enumeration decision
+
+The first implementation uses `SessionPersistence.list()` to obtain materialized headers, filters on `SessionHeader.parentSession`, and calls `load()` only for those direct-child candidates to fold their descriptors. The activation contract calls a preallocated id without a durable header and descriptor an **unmaterialized child**: by-id control reports it as unavailable, while persistence listing omits it. A materialized one-shot child lacks the descriptor and is excluded. This path requires no parent-session catalog event or new persistence backend.
+
+This O(number of direct children) load path is the correctness baseline. If measured scale later requires an index, that index is derived state: session headers and child descriptors remain authoritative, and rebuilding or corruption fallback must reproduce the same results. An index cannot become a second authorization source or make an unmaterialized child visible.
+
+Listing adds no session event and no surface node. It reads the model-hidden descriptor retained in the child log by the activation contract, so compacted and uncompacted children must enumerate identically.
+
+### `list_agents` contract
+
+`SubagentControlService.listChildren(parent)` returns only durable direct children that carry a valid continuable descriptor, then overlays the process-local Task association. The model-facing `list_agents` tool is a thin adapter in `@deepseek-ai/dsh-tool-subagent-control` and reports two operational states:
+
+- `running`: a non-terminal Task-backed activation exists, including startup and settlement before Task terminal publication;
+- `resumable`: a valid durable descriptor exists and no activation is associated.
+
+These values are not `AgentStatus`. A plain Agent registry entry without a Task association is an ownership conflict, not a third list state. Corrupt, unsupported-version, wrong-parent, or missing-child descriptors fail explicitly rather than being silently advertised as resumable.
+
+The first version is read-only and has no child deletion operation. If later product behavior deletes child sessions, persistence listing naturally drops a deleted child; any future derived index must remove or tombstone the same entry so `list_agents` cannot retain stale state.
+
+## Alternatives considered
+
+**Fold listing into the activation RFC.** Descriptor-by-id persistence and cold resume do not require parent-to-child enumeration. Keeping the query separate lets `send_message` land without taking on listing states, scanning performance, or deletion behavior.
+
+**List every persisted session whose header names the parent.** `parentSession` proves lineage but does not prove that the child is continuable. Listing must also load and validate the descriptor.
+
+**Use the live Agent registry as the catalog.** Runs are deliberately disposed after every Task, and registry state disappears on restart. It cannot support durable discovery.
+
+**Persist a parent-session catalog event.** Direct-child headers already provide the durable enumeration seed, and the child descriptor is the reconstruction authority. A second parent log duplicates state and creates cross-session ordering and stale-entry behavior without helping by-id resume.
+
+## Acceptance criteria
+
+- Enumeration uses materialized session headers as candidates, validates `parentSession`, and includes only children whose persisted descriptor satisfies the durable child-handle contract.
+- Listing loads no Agent, appends no session event, and returns the same children from compacted and uncompacted logs.
+- `list_agents` returns only valid direct continuable children and reports `running` or `resumable`, with no pass-through runtime status.
+- Parent resume does not activate children; listing reads durable state and overlays only already-associated process-local Tasks.
+- A preallocated-but-unmaterialized child id, one-shot child, corrupt descriptor, unsupported descriptor version, wrong-parent child, and stale derived-index entry are never advertised as resumable.
+- Keyless tests cover fresh and compacted discovery, restart, wrong-parent access, unsupported descriptors, scan behavior, and stale-index fallback. The model-facing tool has runnable snapshot coverage.
+
+## Risks
+
+- Listing performs one header scan and may load every direct-child log; a later derived index must preserve the same authorization, corruption, and fallback behavior.
+- The first version has no deletion operation, so persisted children remain listed for as long as their sessions remain in persistence even though live Agent resources remain bounded by active Tasks.
+- Task associations exist only in one runtime. Another process can report a durable child as `resumable` while work for that child is active elsewhere unless the deployment adds a shared lease.

+# Agent Note（agent 决策记录）：持久化 subagent 目录与 list_agents
+
+Status: proposed
+
+[English](2026-07-22-durable-subagent-catalog-and-list-agents.md) | 中文
+
+## 问题
+
+可继续的后台 subagent 会公开稳定的 child id，并将重建描述符持久化在该 child 的会话中，因此 `send_message` 无需任何列表查询操作即可恢复已知 child。`list_agents` 的要求不同：parent 重启后，即使调用方不再知道各 child id，也要只枚举该 parent 的直接可继续 child。[可继续的后台 subagent](2026-07-21-continuable-background-subagents.md)负责持久化 child handle 与激活设计；本记录负责枚举及其面向模型的查询。
+
+枚举必须交叉核对不可变的会话谱系、描述符有效性与进程内激活状态，而不能仅为展示就加载或恢复 Agent。它还必须定义缺失、损坏、已删除或不受支持的 child 如何影响列表，以及反复加载大量 child 日志是否需要索引。
+
+## 提案
+
+将 parent 到 child 的枚举与 `list_agents` 作为一个基于持久化 child handle 契约、单独评审的功能。`SubagentControlService.listChildren(parent)` 必须：
+
+- 查找 `parentSession` 将调用方会话标识为 parent 的已实际落盘会话 header；
+- 加载并校验每个候选会话的 `subagent/descriptor` 事件，但不激活 child；
+- 排除一次性、损坏、不受支持、缺失或并非直接 child 的会话；
+- 叠加进程内 Task 关联，但不将该关联视为持久化状态。
+
+描述符格式、持久化、按 id 查找、直接 parent 鉴权与从持久化存储恢复仍由激活提案负责。列表查询消费这些事实，但不能削弱它们，也不能另行发明第二种描述符表示。
+
+### 枚举决策
+
+第一版使用 `SessionPersistence.list()` 获取已实际落盘的 header，按 `SessionHeader.parentSession` 过滤，并且只对这些直接 child 候选调用 `load()` 来归并其描述符。激活契约将已预分配 id、却没有持久化 header 和描述符的 child 称为 **unmaterialized child**：按 id 的控制操作会报告该 id 不可用，持久化列表则不会列出它。已实际落盘的一次性 child 没有描述符，因此会被排除。这条路径无需 parent 会话目录事件或新的持久化后端。
+
+这条 O（直接 child 数量）加载路径是正确性基线。如果实测规模日后需要索引，该索引属于派生状态：会话 header 和 child 描述符仍是权威信息，重建或损坏回退必须复现相同结果。索引不能成为第二个鉴权来源，也不能让尚未实际落盘的 child 变得可见。
+
+列表查询不添加会话事件或 surface 节点。它读取激活契约保留在 child 日志中、对模型隐藏的描述符，因此经过压缩和未经压缩的 child 必须枚举出相同结果。
+
+### `list_agents` 契约
+
+`SubagentControlService.listChildren(parent)` 只返回具有有效可继续描述符的持久化直接 child，再叠加进程内 Task 关联。面向模型的 `list_agents` 工具是 `@deepseek-ai/dsh-tool-subagent-control` 中的轻量适配器，并报告两种操作状态：
+
+- `running`：存在由非终态 Task 支撑的激活，包括启动阶段和 Task 终态发布前的结算阶段；
+- `resumable`：存在有效的持久化描述符，且没有关联任何激活。
+
+这些值并非 `AgentStatus`。普通 Agent 注册表中没有 Task 关联的条目属于所有权冲突，而不是第三种列表状态。描述符损坏、版本不受支持、parent 不匹配或 child 缺失时，系统会明确失败，而不会将其静默标记为可恢复。
+
+第一版只读，不提供 child 删除操作。如果后续产品行为会删除 child 会话，持久化列表会自然移除已删除的 child；任何未来的派生索引都必须移除或 tombstone 同一条目，避免 `list_agents` 保留陈旧状态。
+
+## 已考虑的替代方案
+
+**将列表查询并入激活 RFC。** 按 id 持久化描述符和从持久化存储恢复无需 parent 到 child 的枚举。保持查询独立，可让 `send_message` 落地时不必同时承担列表状态、扫描性能或删除行为。
+
+**枚举 header 中以该 parent 为 parent 的每个持久化会话。** `parentSession` 能证明谱系，却不能证明 child 可继续。列表查询还必须加载并校验描述符。
+
+**使用存活的 Agent 注册表作为目录。** 系统会在每个 Task 结束后有意 dispose 对应 run，而且注册表状态会在重启时消失，因此无法支持持久化发现。
+
+**持久化 parent 会话目录事件。** 直接 child header 已经提供持久化枚举种子，child 描述符则是重建的权威信息。第二份 parent 日志会重复状态，并造成跨会话顺序和陈旧条目行为，却无助于按 id 恢复。
+
+## 验收标准
+
+- 枚举使用已实际落盘的会话 header 作为候选，校验 `parentSession`，并且只包含持久化描述符满足持久化 child handle 契约的 child。
+- 列表查询不加载 Agent、不追加会话事件，并从经过压缩和未经压缩的日志返回相同的 child。
+- `list_agents` 只返回有效的直接可继续 child，并报告 `running` 或 `resumable`，不直接透传运行时状态。
+- 恢复 parent 不会激活 child；列表查询读取持久化状态，并且只叠加已经关联的进程内 Task。
+- 已预分配但尚未实际落盘的 child id、一次性 child、损坏描述符、不受支持的描述符版本、parent 不匹配的 child 和陈旧的派生索引条目绝不会被标记为可恢复。
+- 无密钥测试覆盖压缩前后的发现、重启、错误 parent 访问、不受支持的描述符、扫描行为和陈旧索引回退。面向模型的工具具有可运行的快照覆盖。
+
+## 风险
+
+- 列表查询会扫描一次 header，并且可能加载每个直接 child 的日志；后续的派生索引必须保持相同的鉴权、损坏处理和回退行为。
+- 第一版没有删除操作，因此只要 child 会话仍保留在持久化存储中，它们就会继续出现在列表里，但存活 Agent 资源仍由活跃 Task 数量限制。
+- Task 关联仅存在于一个运行时中。除非部署添加共享租约，否则当另一个进程正在处理某个持久化 child 时，当前进程仍可能将其报告为 `resumable`。

-The first implementation uses `SessionPersistence.list()` to obtain materialized headers, filters on `SessionHeader.parentSession`, and calls `load()` only for those direct-child candidates to fold their descriptors. The activation contract calls a preallocated id without a durable header and descriptor an **unmaterialized child**: by-id control reports it as unavailable, while persistence listing omits it. A materialized one-shot child lacks the descriptor and is excluded. This path requires no parent-session catalog event or new persistence backend.
+The first implementation uses `SessionPersistence.list()` to obtain materialized headers, filters on `SessionHeader.parentSession`, and unions those ids with Task associations owned by the parent. An associated child is resolved from the live association and is never passed to `SessionPersistence.load()`; only inactive direct-child candidates are loaded to fold their descriptors. The activation contract calls a preallocated id without a durable header and descriptor an **unmaterialized child**: by-id control reports an inactive instance as unavailable, but an active association still appears in `list_agents` as `running`. Once that Task becomes terminal, the child remains discoverable only if its durable descriptor validates. A materialized one-shot child lacks the descriptor and is excluded. This path requires no parent-session catalog event or new persistence backend.
 
 This O(number of direct children) load path is the correctness baseline. If measured scale later requires an index, that index is derived state: session headers and child descriptors remain authoritative, and rebuilding or corruption fallback must reproduce the same results. An index cannot become a second authorization source or make an unmaterialized child visible.
 
-Listing adds no session event and no surface node. It reads the model-hidden descriptor retained in the child log by the activation contract, so compacted and uncompacted children must enumerate identically.
+`SessionPersistence.load()` may durably repair an interrupted child log by appending synthetic closing events. The first version accepts this existing persistence side effect: `listChildren()` creates no Agent and appends no catalog or descriptor event itself, but it is not a storage-read-only operation. It reads the model-hidden descriptor retained in the child log by the activation contract, so compacted and uncompacted children must enumerate identically.
 
 ### `list_agents` contract
 
-`SubagentControlService.listChildren(parent)` returns only durable direct children that carry a valid continuable descriptor, then overlays the process-local Task association. The model-facing `list_agents` tool is a thin adapter in `@deepseek-ai/dsh-tool-subagent-control` and reports two operational states:
+`SubagentControlService.listChildren(parent)` returns all direct continuable children in the union of durable candidates and active Task associations, plus non-fatal diagnostics for inactive candidates it could not load, validate, or resume. An association records its creation time when the control service allocates the child id; a materialized child uses `SessionHeader.createdAt`. Children are sorted by that `createdAt` ascending, then child id ascending. Diagnostics follow their candidate's same key. The model-facing `list_agents` tool takes no arguments and is a thin adapter in `@deepseek-ai/dsh-tool-subagent-control`; it renders the complete sorted children and diagnostics together, and reports two operational child states:
 
-- `running`: a non-terminal Task-backed activation exists, including startup and settlement before Task terminal publication;
-- `resumable`: a valid durable descriptor exists and no activation is associated.
+- `running`: a non-terminal Task-backed activation exists, including startup before materialization and settlement before Task terminal publication;
+- `resumable`: no activation is associated, a valid durable descriptor exists, and the named provider is currently registered with `resume?()`.
 
-These values are not `AgentStatus`. A plain Agent registry entry without a Task association is an ownership conflict, not a third list state. Corrupt, unsupported-version, wrong-parent, or missing-child descriptors fail explicitly rather than being silently advertised as resumable.
+These values are not `AgentStatus`. A plain Agent registry entry without a Task association is an ownership conflict, not a third list state. Inactive candidates use three diagnostic reasons: `corrupt` for malformed committed data or descriptor content, `unsupported` for an unknown descriptor version, and `unavailable` when the candidate disappears, another child-specific load fails, or its provider is absent or lacks `resume?()`. Each diagnostic identifies the child id and reason without exposing model-hidden descriptor content; the candidate is omitted while healthy siblings remain visible. Failure of the initial `SessionPersistence.list()` operation fails the whole call because no candidate set exists. Headers whose `parentSession` names another parent are filtered before descriptor loading and produce no diagnostic.
 
-The first version is read-only and has no child deletion operation. If later product behavior deletes child sessions, persistence listing naturally drops a deleted child; any future derived index must remove or tombstone the same entry so `list_agents` cannot retain stale state.

 ## Acceptance criteria
 
-- Enumeration uses materialized session headers as candidates, validates `parentSession`, and includes only children whose persisted descriptor satisfies the durable child-handle contract.
-- Listing loads no Agent, appends no session event, and returns the same children from compacted and uncompacted logs.
-- `list_agents` returns only valid direct continuable children and reports `running` or `resumable`, with no pass-through runtime status.
+- Durable enumeration uses materialized session headers as candidates, validates `parentSession`, and includes only inactive children whose persisted descriptor satisfies the durable child-handle contract; the final result unions those children with parent-owned active associations.
+- Listing loads no Agent and appends no catalog or descriptor event itself, but may trigger `SessionPersistence.load()` interrupted-tail repair for inactive children; an already-associated child is never loaded, and compacted and uncompacted logs return the same children.
+- `list_agents` takes no arguments and returns all valid direct continuable children plus per-child diagnostics, sorted by `createdAt` ascending and child id ascending.
+- Active Task associations appear as `running` even before durable materialization; after Task terminal, the child appears as `resumable` only when its descriptor validates and its currently registered provider implements `resume?()`.
+- `list_agents` reports no pass-through runtime status, uses only `corrupt`, `unsupported`, or `unavailable` diagnostic reasons, and never exposes descriptor contents in a diagnostic.
 - Parent resume does not activate children; listing reads durable state and overlays only already-associated process-local Tasks.
-- A preallocated-but-unmaterialized child id, one-shot child, corrupt descriptor, unsupported descriptor version, wrong-parent child, and stale derived-index entry are never advertised as resumable.
-- Keyless tests cover fresh and compacted discovery, restart, wrong-parent access, unsupported descriptors, scan behavior, and stale-index fallback. The model-facing tool has runnable snapshot coverage.

+- Listing performs one header scan and may load every direct-child log; a later derived index must preserve the same authorization, per-child diagnostic, and fallback behavior.
+- Listing may repair interrupted child logs and persist synthetic closing events even though it creates no Agent. This is the existing `SessionPersistence.load()` contract, not a hidden catalog write.
 - The first version has no deletion operation, so persisted children remain listed for as long as their sessions remain in persistence even though live Agent resources remain bounded by active Tasks.
+- The no-argument tool returns every direct continuable child and diagnostic. Stable ordering makes the result deterministic but does not bound model-context growth; pagination or deletion remains a later product decision.
 - Task associations exist only in one runtime. Another process can report a durable child as `resumable` while work for that child is active elsewhere unless the deployment adds a shared lease.

+Descriptor persistence, by-id lookup, direct-parent authorization, and provider-independent cold resume remain owned by the implemented Activation contract. This proposal extends the descriptor with a durable `label` and requires listing to diagnose duplicate descriptor events; it cannot weaken the existing facts or invent a second descriptor representation.
 
 ### Enumeration decision
 
-The first implementation uses `SessionPersistence.list()` to obtain materialized headers, filters on `SessionHeader.parentSession`, and unions those ids with Task associations owned by the parent. An associated child is resolved from the live association and is never passed to `SessionPersistence.load()`; only inactive direct-child candidates are loaded to fold their descriptors. The activation contract calls a preallocated id without a durable header and descriptor an **unmaterialized child**: by-id control reports an inactive instance as unavailable, but an active association still appears in `list_agents` as `running`. Once that Task becomes terminal, the child remains discoverable only if its durable descriptor validates. A materialized one-shot child lacks the descriptor and is excluded. This path requires no parent-session catalog event or new persistence backend.
+The first implementation consumes `ctx.sessionQuery.traceSession(parent.session.id)` and considers only the trace's first-level descendants. Session query already merges `ctx.sessions` with `ctx.sessionPersistence` using live precedence, preserves immutable-header consistency, derives direct-child lineage from `SessionHeader.parentSession`, and sorts siblings by `createdAt` ascending and child id ascending. `listChildren()` does not reproduce that corpus logic or inspect the continuation manager's process-local Activation map.
 
-This O(number of direct children) load path is the correctness baseline. If measured scale later requires an index, that index is derived state: session headers and child descriptors remain authoritative, and rebuilding or corruption fallback must reproduce the same results. An index cannot become a second authorization source or make an unmaterialized child visible.
+Corpus construction precedes per-child descriptor inspection. A failure while building the initial trace, including persistence listing failure, a live/persisted header conflict anywhere in the observed corpus, or invalid target lineage, fails the whole `list_agents` call because no trustworthy candidate set exists. Only failures after a successful trace are isolated to one candidate; "corrupt child" in that per-child contract therefore means corrupt loaded event surface or descriptor data, not a corpus-level header conflict.
 
-`SessionPersistence.load()` may durably repair an interrupted child log by appending synthetic closing events. The first version accepts this existing persistence side effect: `listChildren()` creates no Agent and appends no catalog or descriptor event itself, but it is not a storage-read-only operation. It reads the model-hidden descriptor retained in the child log by the activation contract, so compacted and uncompacted children must enumerate identically.
+Session lineage is broader than subagent identity: an ordinary `ctx.sessions.fork()` and a one-shot subagent also create direct children. Each candidate must therefore contain exactly one valid `subagent/descriptor` event. The activation contract writes it only during initial creation and cold resume appends no further descriptor; a second event is corruption rather than evidence of another activation. The event distinguishes a continuable background subagent from an ordinary fork or one-shot child; its short creation `label` comes from the delegation's `description`, while its continuation fields remain the reconstruction input for provider-independent cold resume. A candidate without the event is omitted without a diagnostic.
+
+The published logical record is also the status source: `SessionRecord.live` means `running`, while `live: false, persisted: true` means `complete`. `complete` means that no Activation is live; it encodes neither successful completion nor a permanently closed child, and `send_message` may materialize another Activation. Conversely, `running` says only that the session is live: a live Agent outside the continuation manager's matching Activation still appears as `running`, but `send_message` rejects rather than adopting it. A child is not visible before its session is published, and no process-local Activation entry is added as a second candidate or status source. Listing is a snapshot that may race publication, disposal, or a later message; `send_message` remains the authoritative delivery-time operation.

+The subagent service keeps `sessionQuery` optional so start and follow-up remain available without it. Its public `listChildren()` method resolves the optional service when called and throws `SubagentError` with stable code `SUBAGENT_CONTROL_SESSION_QUERY_UNAVAILABLE` before doing any work when it is absent. `@deepseek-ai/dsh-tool-subagent-control` exports separately loadable tool plugins: the `send_message` adapter requires only `subagents`, while the `list_agents` adapter requires both `subagents` and `sessionQuery` at load. A deployment may therefore use `send_message` without loading session query; the list tool catches misconfiguration at plugin load, while another direct service consumer receives the same explicit call-time contract.
+
+This descriptor-read path is the correctness baseline, not a claim that work is linear only in the number of direct children. Let D be the number of direct-child candidates, C the number of persisted sessions scanned by each persistence listing, and L_i the size of candidate i's full log. One corpus trace is followed by two exact reads per candidate. `listChildren()` uses `sessionQuery.listEvents(childId)` to locate the sole descriptor event and `sessionQuery.readEvent({ sessionId: childId, seq })` to read it, and each operation independently loads the logical session. In the persisted-only worst case, every exact read repeats `persistence.list()`, loads the full child log, and clones its events, for O(D × C + Σ L_i) work up to constant factors; a live child instead takes two detached in-memory snapshots of its full log. The persisted path may durably repair an interrupted child log by appending synthetic closing events. The first version accepts the repeated reads as the no-index correctness baseline, but deployments must treat total corpus and child-log size—not only direct-child count—as the capacity constraint. Listing creates no Agent and appends no catalog or descriptor event itself, but it is not a storage-read-only operation. The model-hidden descriptor remains outside the conversation surface and survives compaction, so compacted and uncompacted children must enumerate identically.
+
+If measured scale later requires an index, that index is derived state: session headers and child descriptors remain authoritative, and rebuilding or corruption fallback must reproduce the same results. An index cannot become a second authorization source or make an unpublished child visible.
 
 ### `list_agents` contract
 
-`SubagentControlService.listChildren(parent)` returns all direct continuable children in the union of durable candidates and active Task associations, plus non-fatal diagnostics for inactive candidates it could not load, validate, or resume. An association records its creation time when the control service allocates the child id; a materialized child uses `SessionHeader.createdAt`. Children are sorted by that `createdAt` ascending, then child id ascending. Diagnostics follow their candidate's same key. The model-facing `list_agents` tool takes no arguments and is a thin adapter in `@deepseek-ai/dsh-tool-subagent-control`; it renders the complete sorted children and diagnostics together, and reports two operational child states:
+`SubagentService.listChildren(parent)` returns every direct continuable child found in the session trace plus non-fatal diagnostics for candidates it could not read or validate. Each child carries its session id, descriptor `label`, and one of two snapshot states:
 
-- `running`: a non-terminal Task-backed activation exists, including startup before materialization and settlement before Task terminal publication;
-- `resumable`: no activation is associated, a valid durable descriptor exists, and the named provider is currently registered with `resume?()`.
+- `running`: the logical session record is live in `ctx.sessions`;
+- `complete`: the logical session record exists only in persistence and may be resumed by `send_message`.
 
-These values are not `AgentStatus`. A plain Agent registry entry without a Task association is an ownership conflict, not a third list state. Inactive candidates use three diagnostic reasons: `corrupt` for malformed committed data or descriptor content, `unsupported` for an unknown descriptor version, and `unavailable` when the candidate disappears, another child-specific load fails, or its provider is absent or lacks `resume?()`. Each diagnostic identifies the child id and reason without exposing model-hidden descriptor content; the candidate is omitted while healthy siblings remain visible. Failure of the initial `SessionPersistence.list()` operation fails the whole call because no candidate set exists. Headers whose `parentSession` names another parent are filtered before descriptor loading and produce no diagnostic.
+These values are neither `AgentStatus` nor the manager's internal Activation state. Children are sorted by `SessionHeader.createdAt` ascending, then child id ascending; diagnostics follow their candidate's same key. The model-facing `list_agents` tool takes no arguments and is a thin adapter in `@deepseek-ai/dsh-tool-subagent-control` that renders the complete sorted children and diagnostics together.
+
+Diagnostics use three fixed reasons. Malformed event surfaces, conflicting headers discovered during an exact child load, malformed descriptor content, and multiple descriptor events map to `corrupt`. An unknown descriptor version maps to `unsupported`. `SESSION_QUERY_SESSION_NOT_FOUND`, `SESSION_QUERY_EVENT_NOT_FOUND`, and `SESSION_QUERY_PERSISTENCE_FAILED` from a per-child read map to `unavailable`. This phase boundary is intentional: a persistence outage during the initial trace fails the operation, while the same outage beginning during candidate reads may produce one identical `unavailable` diagnostic per affected child; v1 neither coalesces those diagnostics nor promotes them to a global failure. A missing descriptor is instead a one-shot exclusion without a diagnostic. Configuration/window errors and unrecognized failures are not child diagnostics and propagate as operation failures. Each diagnostic identifies the child id and reason without exposing model-hidden descriptor content; the candidate is omitted while healthy siblings remain visible. Sessions outside the trace's direct descendants are never read and produce no diagnostic.

 ## Acceptance criteria
 
-- Durable enumeration uses materialized session headers as candidates, validates `parentSession`, and includes only inactive children whose persisted descriptor satisfies the durable child-handle contract; the final result unions those children with parent-owned active associations.
-- Listing loads no Agent and appends no catalog or descriptor event itself, but may trigger `SessionPersistence.load()` interrupted-tail repair for inactive children; an already-associated child is never loaded, and compacted and uncompacted logs return the same children.
-- `list_agents` takes no arguments and returns all valid direct continuable children plus per-child diagnostics, sorted by `createdAt` ascending and child id ascending.
-- Active Task associations appear as `running` even before durable materialization; after Task terminal, the child appears as `resumable` only when its descriptor validates and its currently registered provider implements `resume?()`.
-- `list_agents` reports no pass-through runtime status, uses only `corrupt`, `unsupported`, or `unavailable` diagnostic reasons, and never exposes descriptor contents in a diagnostic.
-- Parent resume does not activate children; listing reads durable state and overlays only already-associated process-local Tasks.
-- A preallocated-but-unmaterialized child id, one-shot child, corrupt descriptor, unsupported descriptor version, and stale derived-index entry are never advertised as resumable; non-child headers are filtered before load.
-- A corrupt, unsupported, disappeared, or unloadable candidate cannot hide healthy siblings: it is omitted with an id-and-reason diagnostic, while failure of the initial persistence listing fails the whole call.
-- Keyless tests cover fresh and compacted discovery, active unmaterialized children, transition from running association to durable resume, provider absence, stable ordering, restart, parent-header prefiltering, isolated child diagnostics, load repair, scan behavior, and stale-index fallback. The model-facing complete-list-plus-diagnostics result has runnable snapshot coverage.
+- Enumeration uses `ctx.sessionQuery.traceSession(parent.session.id)`, considers only direct descendants, and does not duplicate corpus merging, lineage reconstruction, or sibling ordering.
+- Listing loads no Agent, materializes no Activation, and appends no catalog or descriptor event itself. After the initial trace it performs two independent exact session-query reads per candidate; persisted reads may trigger interrupted-tail repair, and compacted and uncompacted logs return the same children.
+- A valid descriptor includes the delegation's durable `label`; ordinary session forks and one-shot children lack that descriptor and are omitted without a diagnostic. Provider registration does not affect discovery or provider-independent cold resume.
+- Initial creation writes exactly one descriptor event, cold resume writes none, and a candidate with more than one descriptor event is diagnosed as `corrupt`.
+- `list_agents` takes no arguments and returns every valid direct continuable child with its id, label, and `running` or `complete` snapshot state, plus per-child diagnostics, sorted by `createdAt` ascending and child id ascending.
+- A live logical session is `running`; a persisted-only logical session is `complete` and remains eligible for a later `send_message`. The result does not consult the process-local Activation map.
+- Parent resume does not activate children. A child is absent until its session is published, and listing may race publication, disposal, or later delivery without weakening `send_message`'s execution-time checks.
+- `list_agents` uses only `corrupt`, `unsupported`, or `unavailable` diagnostic reasons and never exposes descriptor contents in a diagnostic.
+- After a successful initial trace, a corrupt, unsupported, disappeared, or unreadable descriptor candidate cannot hide healthy siblings: it is omitted with an id-and-reason diagnostic. Corpus-level persistence, header-consistency, or lineage failure during that initial trace fails the whole call.
+- Per-child session-query failures map deterministically: invalid surfaces and exact-load source conflicts are `corrupt`; missing sessions or events and persistence failures are `unavailable`; unknown descriptor versions are `unsupported`; and missing descriptors are omitted as one-shot children.
+- The list tool requires `sessionQuery` at plugin load; a direct `listChildren()` call without it fails before enumeration with `SUBAGENT_CONTROL_SESSION_QUERY_UNAVAILABLE`, while by-id `send_message` remains usable without that service.
+- Keyless tests cover fresh and compacted discovery, ordinary fork and one-shot exclusion, live-to-complete transition, unmanaged-live-session snapshots, provider-independent discovery, durable `label` values, stable ordering, restart, direct-child tracing, duplicate descriptor rejection, isolated child diagnostics, phase-dependent persistence failure, load repair, snapshot races, and scan behavior. The model-facing complete-list-plus-diagnostics result has runnable snapshot coverage.
 
 ## Risks
 
-- Listing performs one header scan and may load every direct-child log; a later derived index must preserve the same authorization, per-child diagnostic, and fallback behavior.
-- Listing may repair interrupted child logs and persist synthetic closing events even though it creates no Agent. This is the existing `SessionPersistence.load()` contract, not a hidden catalog write.
-- The first version has no deletion operation, so persisted children remain listed for as long as their sessions remain in persistence even though live Agent resources remain bounded by active Tasks.
+- Session tracing observes the complete logical corpus, then descriptor validation reads each direct-child log twice. In the persisted-only worst case, work is O(D × C + Σ L_i), not merely O(D), because each exact read rescans persistence and loads and clones the full candidate log. A later derived index must preserve the same authorization, per-child diagnostic, and fallback behavior.
+- Corpus construction is an all-or-nothing trust boundary: one live/persisted header conflict can fail the initial trace and hide otherwise healthy siblings. Per-child isolation begins only after that trace succeeds.
+- Session-query reads may repair interrupted child logs and persist synthetic closing events even though listing creates no Agent. This is the existing persistence-load contract, not a hidden catalog write.
+- The first version has no deletion operation, so persisted children remain listed for as long as their sessions remain in persistence even though live Agent resources remain bounded by resident Activations.
 - The no-argument tool returns every direct continuable child and diagnostic. Stable ordering makes the result deterministic but does not bound model-context growth; pagination or deletion remains a later product decision.
-- Task associations exist only in one runtime. Another process can report a durable child as `resumable` while work for that child is active elsewhere unless the deployment adds a shared lease.
+- `running` and `complete` are process-local corpus snapshots, not delivery promises. Another process may activate a persisted child while this process reports it as `complete`; cross-process accuracy requires a shared lease.

 ### 枚举决策
 
-第一版使用 `SessionPersistence.list()` 获取已实际落盘的 header，按 `SessionHeader.parentSession` 过滤，再将这些 id 与 parent 拥有的 Task 关联合并。已关联的 child 直接从存活关联中解析，绝不会传给 `SessionPersistence.load()`；只有非活跃的直接 child 候选才会被加载以归并其描述符。激活契约将已预分配 id、却没有持久化 header 和描述符的 child 称为 **unmaterialized child**：按 id 的控制操作会报告非活跃实例不可用，但活跃关联仍会在 `list_agents` 中显示为 `running`。该 Task 进入终态后，只有在持久化描述符通过校验时，这个 child 才会继续可被发现。已实际落盘的一次性 child 没有描述符，因此会被排除。这条路径无需 parent 会话目录事件或新的持久化后端。
+第一版消费 `ctx.sessionQuery.traceSession(parent.session.id)`，并且只考虑追踪结果的第一层后代。会话查询已经使用实时优先规则合并 `ctx.sessions` 与 `ctx.sessionPersistence`，保持不可变 header 一致性，根据 `SessionHeader.parentSession` 推导直接 child 谱系，并按 `createdAt` 升序、child id 升序排列 sibling。`listChildren()` 不会重复实现这套语料逻辑，也不会检查继续执行管理器的进程内 Activation map。
 
-这条 O（直接 child 数量）加载路径是正确性基线。如果实测规模日后需要索引，该索引属于派生状态：会话 header 和 child 描述符仍是权威信息，重建或损坏回退必须复现相同结果。索引不能成为第二个鉴权来源，也不能让尚未实际落盘的 child 变得可见。
+语料构建先于逐 child 描述符检查。构建初始追踪时如果发生持久化列表查询失败、所观测语料中任意位置的存活／持久化 header 冲突或目标谱系无效，整个 `list_agents` 调用都会失败，因为此时不存在可信的候选集。只有初始追踪成功后的失败才会被隔离到单个候选；因此，这项逐 child 契约中的“损坏 child”是指已加载的事件 surface 或描述符数据损坏，而不是语料级 header 冲突。
 
-`SessionPersistence.load()` 可能通过追加合成的结束事件，持久修复中断的 child 日志。第一版接受这项现有的持久化副作用：`listChildren()` 不会创建 Agent，也不会自行追加目录或描述符事件，但它并非严格的存储只读操作。它读取激活契约保留在 child 日志中、对模型隐藏的描述符，因此经过压缩和未经压缩的 child 必须枚举出相同结果。
+会话谱系涵盖的范围比 subagent 身份更广：普通 `ctx.sessions.fork()` 和一次性 subagent 也会创建直接 child。因此，每个候选都必须恰好包含一个有效的 `subagent/descriptor` 事件。激活契约只在初始创建期间写入该事件，从持久化存储恢复时不会追加其他描述符；第二个事件属于损坏，而不是另一次激活的证据。该事件用于区分可继续的后台 subagent 与普通 fork 或一次性 child；其简短创建 `label` 来自委派的 `description`，其余继续执行字段仍是不依赖提供方的冷恢复所使用的重建输入。缺少该事件的候选会被排除，且不产生 diagnostic。
+
+已发布的逻辑记录同时也是状态来源：`SessionRecord.live` 表示 `running`，而 `live: false, persisted: true` 表示 `complete`。`complete` 表示当前没有存活的 Activation，既不表示执行成功，也不表示 child 已永久关闭；`send_message` 仍可物化另一次 Activation。反过来，`running` 只表示会话存活：位于继续执行管理器对应 Activation 之外的存活 Agent 仍会显示为 `running`，但 `send_message` 会拒绝，而不会接管它。child 会话发布前不可见，也不会添加进程内 Activation 条目作为第二个候选来源或状态来源。列表查询是一份快照，可能与发布、dispose 或后续消息发生竞态；`send_message` 仍是消息送达时的权威操作。
+
+subagent 服务将 `sessionQuery` 保持为可选依赖，因此没有该服务时仍可执行 start 和 follow-up。其公开的 `listChildren()` 方法在调用时解析这个可选服务；如果服务缺失，该方法会在执行任何工作前抛出 `SubagentError`，并携带稳定错误码 `SUBAGENT_CONTROL_SESSION_QUERY_UNAVAILABLE`。`@deepseek-ai/dsh-tool-subagent-control` 导出可分别加载的工具插件：`send_message` 适配器只要求 `subagents`，而 `list_agents` 适配器在加载时同时要求 `subagents` 和 `sessionQuery`。因此，部署可以在不加载会话查询的情况下使用 `send_message`；列表工具会在插件加载时捕获配置错误，而其他直接服务消费方会收到同一项明确的调用时契约。
+
+这条描述符读取路径是正确性基线，并不声称工作量只与直接 child 数量呈线性关系。令 D 为直接 child 候选数量，C 为每次持久化列表查询所扫描的持久化会话数量，L_i 为候选 i 的完整日志大小。一次语料追踪后，每个候选会执行两次精确读取。`listChildren()` 使用 `sessionQuery.listEvents(childId)` 定位唯一的描述符事件，并使用 `sessionQuery.readEvent({ sessionId: childId, seq })` 读取该事件；每项操作都会独立加载逻辑会话。对于只存在于持久化存储中的最坏情况，每次精确读取都会重复执行 `persistence.list()`、加载完整 child 日志并克隆其中的事件，因此忽略常数因子后的工作量为 O(D × C + Σ L_i)；存活 child 则会对其完整日志取得两份分离的内存快照。持久化路径可能通过追加合成的结束事件，持久修复中断的 child 日志。第一版接受这些重复读取，将其作为无索引的正确性基线，但部署必须将语料总量和 child 日志大小，而不仅是直接 child 数量，视为容量约束。列表查询不会创建 Agent，也不会自行追加目录或描述符事件，但它并非严格的存储只读操作。对模型隐藏的描述符始终位于对话 surface 之外，并且会在压缩后保留，因此经过压缩和未经压缩的 child 必须枚举出相同结果。
+
+如果实测规模日后需要索引，该索引属于派生状态：会话 header 和 child 描述符仍是权威信息，重建或损坏回退必须复现相同结果。索引不能成为第二个鉴权来源，也不能让尚未发布的 child 变得可见。
 
 ### `list_agents` 契约
 
-`SubagentControlService.listChildren(parent)` 返回持久化候选与活跃 Task 关联并集中的所有直接可继续 child，以及无法加载、校验或恢复非活跃候选时产生的非致命 diagnostic。控制服务分配 child id 时，关联会记录其创建时间；已实际落盘的 child 则使用 `SessionHeader.createdAt`。这些 child 先按该 `createdAt` 升序、再按 child id 升序排序，diagnostic 使用其候选的同一排序键。面向模型的 `list_agents` 工具不接受参数，它是 `@deepseek-ai/dsh-tool-subagent-control` 中的轻量适配器；它会一并渲染完整的已排序 child 和 diagnostic，并报告两种 child 操作状态：
+`SubagentService.listChildren(parent)` 返回会话追踪中找到的每个直接可继续 child，以及无法读取或校验候选时产生的非致命 diagnostic。每个 child 都携带自己的 session id、描述符 `label`，以及两种快照状态之一：
 
-- `running`：存在由非终态 Task 支撑的激活，包括实际落盘前的启动阶段和 Task 终态发布前的结算阶段；
-- `resumable`：没有关联任何激活，存在有效的持久化描述符，且其指定的提供方当前已注册并实现 `resume?()`。
+- `running`：逻辑会话记录在 `ctx.sessions` 中存活；
+- `complete`：逻辑会话记录只存在于持久化存储中，并且可以由 `send_message` 恢复。
 
-这些值并非 `AgentStatus`。普通 Agent 注册表中没有 Task 关联的条目属于所有权冲突，而不是第三种列表状态。非活跃候选使用三种固定的 diagnostic 原因：格式错误的已提交数据或描述符内容使用 `corrupt`，未知描述符版本使用 `unsupported`，候选消失、出现其他逐 child 加载失败、其提供方缺失或未实现 `resume?()` 时使用 `unavailable`。每条 diagnostic 都标识 child id 及原因，不暴露对模型隐藏的描述符内容；系统会排除该候选，而其他健康的 sibling 仍然可见。如果初始 `SessionPersistence.list()` 操作失败，因为系统无法获得候选集，整次调用都会失败。`parentSession` 指向其他 parent 的 header 会在加载描述符前被过滤，且不产生 diagnostic。
+这些值既不是 `AgentStatus`，也不是管理器内部的 Activation 状态。child 按 `SessionHeader.createdAt` 升序、再按 child id 升序排序；diagnostic 使用其候选的同一排序键。面向模型的 `list_agents` 工具不接受参数，它是 `@deepseek-ai/dsh-tool-subagent-control` 中的轻量适配器，会一并渲染完整的已排序 child 和 diagnostic。
+
+diagnostic 使用三种固定原因。格式错误的事件 surface、精确加载 child 时发现的 header 冲突、格式错误的描述符内容和多个描述符事件映射为 `corrupt`。未知描述符版本映射为 `unsupported`。逐 child 读取产生的 `SESSION_QUERY_SESSION_NOT_FOUND`、`SESSION_QUERY_EVENT_NOT_FOUND` 和 `SESSION_QUERY_PERSISTENCE_FAILED` 映射为 `unavailable`。这项阶段边界是有意为之：初始追踪期间发生持久化故障会让操作失败，而同一故障如果始于候选读取期间，可能会让每个受影响的 child 分别产生一条相同的 `unavailable` diagnostic；第一版既不合并这些 diagnostic，也不会把它们提升为全局失败。缺少描述符则视为一次性 child，直接排除且不产生 diagnostic。配置错误、窗口错误和未识别的失败不属于 child diagnostic，会作为操作失败继续向上传播。每条 diagnostic 都标识 child id 及原因，不暴露对模型隐藏的描述符内容；系统会排除该候选，而其他健康的 sibling 仍然可见。系统绝不会读取不属于追踪结果直接后代的会话，也不会为它们产生 diagnostic。
 
 第一版不提供 child 删除操作。如果后续产品行为会删除 child 会话，持久化列表会自然移除已删除的 child；任何未来的派生索引都必须移除或 tombstone 同一条目，避免 `list_agents` 保留陈旧状态。

+- 逐 child 会话查询失败采用固定映射：无效 surface 和精确加载时的来源冲突映射为 `corrupt`；会话或事件缺失以及持久化失败映射为 `unavailable`；未知描述符版本映射为 `unsupported`；缺少描述符则作为一次性 child 排除。
+- 列表工具在插件加载时要求 `sessionQuery`；直接调用 `listChildren()` 时如果缺少该服务，则会在枚举前以 `SUBAGENT_CONTROL_SESSION_QUERY_UNAVAILABLE` 失败，而按 id 的 `send_message` 在没有该服务时仍可使用。

 ## 风险
 
-- 列表查询会扫描一次 header，并且可能加载每个直接 child 的日志；后续的派生索引必须保持相同的鉴权、逐 child diagnostic 和回退行为。
-- 列表查询可能修复中断的 child 日志并持久化合成的结束事件，即使它不创建 Agent。这是 `SessionPersistence.load()` 的现有契约，而非隐藏的目录写入。
-- 第一版没有删除操作，因此只要 child 会话仍保留在持久化存储中，它们就会继续出现在列表里，但存活 Agent 资源仍由活跃 Task 数量限制。
+- 会话追踪会观察完整的逻辑语料，随后描述符校验会读取每个直接 child 的日志两次。对于只存在于持久化存储中的最坏情况，工作量为 O(D × C + Σ L_i)，而不只是 O(D)，因为每次精确读取都会重新扫描持久化存储，并加载和克隆候选的完整日志。后续的派生索引必须保持相同的鉴权、逐 child diagnostic 和回退行为。
+- 语料构建是一个全有或全无的信任边界：一处存活／持久化 header 冲突就可能导致初始追踪失败，并隐藏原本健康的 sibling。只有初始追踪成功后，逐 child 隔离才会生效。
+- 会话查询读取可能修复中断的 child 日志并持久化合成的结束事件，即使列表查询不创建 Agent。这是现有的持久化加载契约，而非隐藏的目录写入。
+- 第一版没有删除操作，因此只要 child 会话仍保留在持久化存储中，它们就会继续出现在列表里，但存活 Agent 资源仍由驻留 Activation 数量限制。
 - 无参数工具会返回每个直接可继续 child 和 diagnostic。稳定排序可使结果确定，但不会限制模型上下文的增长；分页或删除仍是后续的产品决策。
-- Task 关联仅存在于一个运行时中。除非部署添加共享租约，否则当另一个进程正在处理某个持久化 child 时，当前进程仍可能将其报告为 `resumable`。
+- `running` 和 `complete` 是进程内语料快照，而非消息送达承诺。另一个进程可能在当前进程将某个持久化 child 报告为 `complete` 时激活它；跨进程准确性需要共享租约。

 ### Enumeration decision
 
-The first implementation consumes `ctx.sessionQuery.traceSession(parent.session.id)` and considers only the trace's first-level descendants. Session query already merges `ctx.sessions` with `ctx.sessionPersistence` using live precedence, preserves immutable-header consistency, derives direct-child lineage from `SessionHeader.parentSession`, and sorts siblings by `createdAt` ascending and child id ascending. `listChildren()` does not reproduce that corpus logic or inspect the continuation manager's process-local Activation map.
+The first implementation consumes `ctx.sessionQuery.traceSession(parentSessionId)` and considers only the trace's first-level descendants. The target may be live or persisted; tracing the logical corpus does not load or resume an Agent. Session query already merges `ctx.sessions` with `ctx.sessionPersistence` using live precedence, preserves immutable-header consistency, derives direct-child lineage from `SessionHeader.parentSession`, and sorts siblings by `createdAt` ascending and child id ascending. `listChildren()` does not reproduce that corpus logic or inspect the continuation manager's process-local Activation map.
 
 Corpus construction precedes per-child descriptor inspection. A failure while building the initial trace, including persistence listing failure, a live/persisted header conflict anywhere in the observed corpus, or invalid target lineage, fails the whole `list_agents` call because no trustworthy candidate set exists. Only failures after a successful trace are isolated to one candidate; "corrupt child" in that per-child contract therefore means corrupt loaded event surface or descriptor data, not a corpus-level header conflict.
 
-Session lineage is broader than subagent identity: an ordinary `ctx.sessions.fork()` and a one-shot subagent also create direct children. Each candidate must therefore contain exactly one valid `subagent/descriptor` event. The activation contract writes it only during initial creation and cold resume appends no further descriptor; a second event is corruption rather than evidence of another activation. The event distinguishes a continuable background subagent from an ordinary fork or one-shot child; its short creation `label` comes from the delegation's `description`, while its continuation fields remain the reconstruction input for provider-independent cold resume. A candidate without the event is omitted without a diagnostic.
+Session lineage is broader than subagent identity: an ordinary `ctx.sessions.fork()` and a one-shot subagent also create direct children. The session header gains no `kind` discriminator; each candidate must instead contain exactly one valid `subagent/descriptor` event. The Activation contract writes it only during initial creation and cold resume appends no further descriptor; a second event is corruption rather than evidence of another Activation. The event is the sole evidence that a traced child is a continuable background subagent; its short creation `label` comes from the delegation's `description`, while its continuation fields remain the reconstruction input for provider-independent cold resume. A candidate without the event is an ordinary fork, one-shot child, or another non-continuable session and is omitted without a diagnostic.
 
-The published logical record is also the status source: `SessionRecord.live` means `running`, while `live: false, persisted: true` means `complete`. `complete` means that no Activation is live; it encodes neither successful completion nor a permanently closed child, and `send_message` may materialize another Activation. Conversely, `running` says only that the session is live: a live Agent outside the continuation manager's matching Activation still appears as `running`, but `send_message` rejects rather than adopting it. A child is not visible before its session is published, and no process-local Activation entry is added as a second candidate or status source. Listing is a snapshot that may race publication, disposal, or a later message; `send_message` remains the authoritative delivery-time operation.
+The published logical record is also the status source: `SessionRecord.live` means `running`, while `live: false, persisted: true` means `complete`.

-The subagent service keeps `sessionQuery` optional so start and follow-up remain available without it. Its public `listChildren()` method resolves the optional service when called and throws `SubagentError` with stable code `SUBAGENT_CONTROL_SESSION_QUERY_UNAVAILABLE` before doing any work when it is absent. `@deepseek-ai/dsh-tool-subagent-control` exports separately loadable tool plugins: the `send_message` adapter requires only `subagents`, while the `list_agents` adapter requires both `subagents` and `sessionQuery` at load. A deployment may therefore use `send_message` without loading session query; the list tool catches misconfiguration at plugin load, while another direct service consumer receives the same explicit call-time contract.

-This descriptor-read path is the correctness baseline, not a claim that work is linear only in the number of direct children. Let D be the number of direct-child candidates, C the number of persisted sessions scanned by each persistence listing, and L_i the size of candidate i's full log. One corpus trace is followed by two exact reads per candidate. `listChildren()` uses `sessionQuery.listEvents(childId)` to locate the sole descriptor event and `sessionQuery.readEvent({ sessionId: childId, seq })` to read it, and each operation independently loads the logical session. In the persisted-only worst case, every exact read repeats `persistence.list()`, loads the full child log, and clones its events, for O(D × C + Σ L_i) work up to constant factors; a live child instead takes two detached in-memory snapshots of its full log. The persisted path may durably repair an interrupted child log by appending synthetic closing events. The first version accepts the repeated reads as the no-index correctness baseline, but deployments must treat total corpus and child-log size—not only direct-child count—as the capacity constraint. Listing creates no Agent and appends no catalog or descriptor event itself, but it is not a storage-read-only operation. The model-hidden descriptor remains outside the conversation surface and survives compaction, so compacted and uncompacted children must enumerate identically.
+This descriptor-read path is the correctness baseline, not a claim that work is linear only in the number of direct children. Let D be the number of direct-child candidates, C be the number of persisted sessions scanned by each persistence listing, and L_i be the size of candidate i's full log. One corpus trace is followed by `sessionQuery.listEvents(childId)` for every candidate. A candidate with no descriptor is omitted, and one with multiple descriptors is diagnosed without another read; only a candidate with exactly one descriptor is loaded again through `sessionQuery.readEvent({ sessionId: childId, seq })`. The read must return the same immutable session header observed by the trace, including the direct-parent relationship, and its target must still be the located descriptor event; a mismatch is per-child corruption. In the persisted-only worst case, each exact read repeats `persistence.list()`, loads the full child log, and clones its events, for O(D × C + Σ L_i) work up to constant factors; a candidate with exactly one descriptor pays those costs twice, while other candidates pay them once. A live candidate similarly takes one detached in-memory snapshot of its full log, or two when its descriptor is read. The persisted path may durably repair an interrupted child log by appending synthetic closing events.

The model-hidden descriptor remains outside the conversation surface and survives compaction, so compacted and uncompacted children must enumerate identically.
 
 If measured scale later requires an index, that index is derived state: session headers and child descriptors remain authoritative, and rebuilding or corruption fallback must reproduce the same results. An index cannot become a second authorization source or make an unpublished child visible.
 
 ### `list_agents` contract
 
-`SubagentService.listChildren(parent)` returns every direct continuable child found in the session trace plus non-fatal diagnostics for candidates it could not read or validate. Each child carries its session id, descriptor `label`, and one of two snapshot states:
+`SubagentService.listChildren(parentSessionId: SessionId)` returns `Promise`, one array preserving the trace's candidate order rather than separate child and diagnostic arrays. `SubagentListEntry` is a closed union discriminated by its readonly `kind`:
 
-- `running`: the logical session record is live in `ctx.sessions`;
-- `complete`: the logical session record exists only in persistence and may be resumed by `send_message`.
+- `kind: 'child'` carries readonly `id: SessionId`, durable `label: string`, and `status: 'running' | 'complete'`;
+- `kind: 'diagnostic'` carries readonly `id: SessionId` and `reason: 'corrupt' | 'unsupported' | 'unavailable'`.
 
-These values are neither `AgentStatus` nor the manager's internal Activation state. Children are sorted by `SessionHeader.createdAt` ascending, then child id ascending; diagnostics follow their candidate's same key. The model-facing `list_agents` tool takes no arguments and is a thin adapter in `@deepseek-ai/dsh-tool-subagent-control` that renders the complete sorted children and diagnostics together.
+A valid descriptor produces one child entry, a per-child inspection failure produces one diagnostic entry, and a candidate without a descriptor produces no entry. Child status `running` means that the logical record is live in `ctx.sessions`; `complete` means that it exists only in persistence. These values are neither `AgentStatus` nor the manager's internal Activation state, and the result does not expose the internal `createdAt` sorting key. Exact Activation states and durable outcomes such as successful completion, failure, cancellation, and stop reason require a separate durable activation record and are outside this proposal.
 
-Diagnostics use three fixed reasons. Malformed event surfaces, conflicting headers discovered during an exact child load, malformed descriptor content, and multiple descriptor events map to `corrupt`. An unknown descriptor version maps to `unsupported`. `SESSION_QUERY_SESSION_NOT_FOUND`, `SESSION_QUERY_EVENT_NOT_FOUND`, and `SESSION_QUERY_PERSISTENCE_FAILED` from a per-child read map to `unavailable`. This phase boundary is intentional: a persistence outage during the initial trace fails the operation, while the same outage beginning during candidate reads may produce one identical `unavailable` diagnostic per affected child; v1 neither coalesces those diagnostics nor promotes them to a global failure. A missing descriptor is instead a one-shot exclusion without a diagnostic. Configuration/window errors and unrecognized failures are not child diagnostics and propagate as operation failures. Each diagnostic identifies the child id and reason without exposing model-hidden descriptor content; the candidate is omitted while healthy siblings remain visible. Sessions outside the trace's direct descendants are never read and produce no diagnostic.
