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).

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. Missing measurement or metadata stays absent. +The tail `session.history` response carries durable usage and pressure, while older pages omit them. Live changes use `session/metrics` mux frames.

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.

Allowed prompt content and every additional context become separate model-facing `user/message` events before the turn runs. A listener that wraps a downstream allow preserves its `content` and `additionalContexts` unless it intentionally replaces either field; the returned allow is authoritative. diff --git a/packages/core/agent/README.zh.md b/packages/core/agent/README.zh.md index 531db9905b..d9adbe2001 100644 --- a/packages/core/agent/README.zh.md +++ b/packages/core/agent/README.zh.md @@ -48,7 +48,7 @@ Agent *创建* 由实现 `AgentFactory` 的插件（`dsh-agent-loop`）提供， 生命周期边有两个重要的本地注意事项。`agent/created` 在作用域 setup 之后、会话与 agent 注册表条目都存在之后运行。Setup 是受信任、仅用于组合的代码；紧随其后且不可 veto 的 `agent/session-start` 通知是第一个受支持的启动注入点。`agent/disposed` 始终表示确切 agent 已离开注册表。AgentLoop 在其驱动器静默后发出该事件，而有序 teardown 此时可能仍在分离会话并撤销作用域；直接注册的自定义 agent 自行拥有任何更强的驱动器顺序契约。 -大多数拦截点都是协作式 waterfall。轮次作用域的异步 seam 接收一个显式 `AbortSignal`，其中 `signal` 紧邻 waterfall 最终的 `next`；监听器可以配合，但不得将它保留为控制另一轮次的权限。`agent/step` 是派生请求前的串行检查点，而 `agent/request-error` 是失败模型请求的恢复 waterfall：失败步骤关闭后，它接收确切错误、规范化失败事实和信号。拥有恢复权的监听器返回 `{ kind: 'retry' }` 且不调用 `next()`；循环会关闭失败轮次，并打开一个编号重试轮次。`agent/turn-stopping` 在本可完成的轮次关闭前运行。普通排队提示词保持原样。有效的广义取消会先发出只观测的 `agent/cancel-requested` 及其解析后的类型化原因，再清空队列并中止；通知失败会被收容，不能 veto 停止。信号生命周期由[显式取消决策](../../../.agents/notes/implemented/architecture/2026-07-16-explicit-turn-cancellation.md)拥有；作用域分发与终止结算由 [agent 作用域 runtime 设计 Agent Note](../../../.agents/notes/implemented/architecture/2026-07-12-agent-scope-runtime-design.md#three-execution-boundaries-are-deliberately-one-way)拥有。 +大多数拦截点都是协作式 waterfall。轮次作用域的异步 seam 接收一个显式 `AbortSignal`，其中 `signal` 紧邻 waterfall 最终的 `next`；监听器可以配合，但不得将它保留为控制另一轮次的权限。`agent/step` 是派生请求前的串行检查点；`agent/model-request` 是失败会被收容的通知，它会报告最终已分派路由及可选的、与注册项绑定的上下文容量，但不会成为持久状态。`agent/request-error` 是失败模型请求的恢复 waterfall：失败步骤关闭后，它接收确切错误、规范化失败事实和信号。拥有恢复权的监听器返回 `{ kind: 'retry' }` 且不调用 `next()`；循环会关闭失败轮次，并打开一个编号重试轮次。`agent/turn-stopping` 在本可完成的轮次关闭前运行。普通排队提示词保持原样。有效的广义取消会先发出只观测的 `agent/cancel-requested` 及其解析后的类型化原因，再清空队列并中止；通知失败会被收容，不能 veto 停止。信号生命周期由[显式取消决策](../../../.agents/notes/implemented/architecture/2026-07-16-explicit-turn-cancellation.md)拥有；作用域分发与终止结算由 [agent 作用域 runtime 设计 Agent Note](../../../.agents/notes/implemented/architecture/2026-07-12-agent-scope-runtime-design.md#three-execution-boundaries-are-deliberately-one-way)拥有。 `PromptDecision.additionalContexts` 是数组，因此每个上下文都保留自己的来源。获准的提示词内容与每个附加上下文都会在轮次运行前成为各自独立、面向模型的 `user/message` 事件。包装下游允许决策的监听器会保留其 `content` 与 `additionalContexts`，除非有意替换任一字段；返回的允许决策是权威来源。 diff --git a/packages/core/agent/src/types.ts b/packages/core/agent/src/types.ts index b61ebadb86..5aac3152b2 100644 --- a/packages/core/agent/src/types.ts +++ b/packages/core/agent/src/types.ts @@ -116,6 +116,16 @@ export type PromptDecision = /** Model-request failure with an optional machine-routable provider code. */ export type RequestError = Error & { code?: string } +/** Live metadata for one model request that reached adapter dispatch. */ +export interface AgentModelRequest { + /** Final registered provider route. */ + readonly provider: string + /** Final adapter-owned model id. */ + readonly model: string + /** Registration-bound context capacity when the adapter exposed one. */ + readonly contextWindow?: number +} + /** Action returned by a listener that owns model-request recovery. */ export type RequestErrorAction = { kind: 'retry' } | undefined @@ -360,6 +370,20 @@ declare module 'cordis' { * @mode waterfall */ 'agent/request'(this: Scoped, agent: Agent, turn: number, step: number, signal: AbortSignal, next: () => Promise): Promise + /** + * One model request constructed its final stream handle and is about to + * iterate it.

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.

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. +After `agent/request` returns a provider/model call config, the loop asks `ctx.llm.prepareCall()` to validate any adapter-owned reasoning effort, materialize its configured default, and retain available context metadata from that same exact-model lookup under the active turn signal. 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. Once the final provider/model is fixed and the outer `llm/stream` call returns a handle, the loop emits one contained live `agent/model-request` notification with turn, step, route, and optional registration-bound capacity. This is an observed Agent-loop attempt, not proof of provider I/O: preparation or a synchronous outer waterfall failure emits nothing, while a short-circuit handle or later lazy adapter construction, failure, or abortion still counts. 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. The [explicit-cancellation decision](../../../.agents/notes/implemented/architecture/2026-07-16-explicit-turn-cancellation.md) owns the lifecycle and race contract. diff --git a/packages/core/agent-loop/README.zh.md b/packages/core/agent-loop/README.zh.md index f8cc972e95..cf561a0328 100644 --- a/packages/core/agent-loop/README.zh.md +++ b/packages/core/agent-loop/README.zh.md @@ -62,7 +62,7 @@ interface Config { 每次提供方调用成功结束时，都会恰好追加一个 `assistant/message` 完成锚点，包括无内容调用和以 `max-tokens` 结束的调用。该锚点原样记录组装后的内容，保留确切的 chunk 溯源（流没有 chunk 时为 `[]`），并在用量可用时包含用量；空内容不会进入派生消息历史。 -在 `agent/request` 返回提供方／模型调用配置后，循环会调用 `ctx.llm.prepareCall()`，在活跃轮次信号的控制下校验由适配器持有的推理（reasoning）强度、填入其配置默认值，并从同一次精确模型查询中保留可用的上下文元数据。准备完成的调用会在这次异步解析、`request/header` 日志记录和最终分派期间保留同一项确切的适配器注册，因此 HMR（热模块替换）不会把某个适配器的能力解析结果与另一适配器的请求混用。最终流句柄构造完成后、适配器开始迭代前，循环会发出一条失败会被收容的实时 `agent/model-request` 通知，其中包含轮次、步骤、最终提供方／模型，以及可选的、与注册项绑定的容量。准备阶段失败或同步流构造失败不会发出通知；之后即使失败或中止，该请求仍视为已观察到的分派。生效配置会在分派前写入日志，因此监听器可以在步骤之间更改推理强度，而不会产生未记录的请求变化。没有已注册适配器的路由会保留原定配置，使 `llm/stream` 监听器可以接管并短路该请求；最终分派仍会以 `NO_ADAPTER` 拒绝未得到处理的路由。新循环实例仅在初始提供方／模型路由与日志路由完全一致时恢复上次的推理强度；路由变化会丢弃由前一模型持有的不透明 ID，并单独解析新模型。 +在 `agent/request` 返回提供方／模型调用配置后，循环会调用 `ctx.llm.prepareCall()`，在活跃轮次信号的控制下校验由适配器持有的推理（reasoning）强度、填入其配置默认值，并从同一次精确模型查询中保留可用的上下文元数据。准备完成的调用会在这次异步解析、`request/header` 日志记录和最终分派期间保留同一项确切的适配器注册，因此 HMR（热模块替换）不会把某个适配器的能力解析结果与另一适配器的请求混用。最终提供方／模型确定且外层 `llm/stream` 调用返回句柄后，循环会发出一条失败会被收容的实时 `agent/model-request` 通知，其中包含轮次、步骤、路由，以及可选的、与注册项绑定的容量。这是 agent loop 观察到的一次尝试，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，而短路句柄或之后的惰性适配器构造、失败或中止仍会计入。生效配置会在分派前写入日志，因此监听器可以在步骤之间更改推理强度，而不会产生未记录的请求变化。没有已注册适配器的路由会保留原定配置，使 `llm/stream` 监听器可以接管并短路该请求；最终分派仍会以 `NO_ADAPTER` 拒绝未得到处理的路由。新循环实例仅在初始提供方／模型路由与日志路由完全一致时恢复上次的推理强度；路由变化会丢弃由前一模型持有的不透明 ID，并单独解析新模型。 插件失败会结束当前轮次，而不是结束循环。只有最终适配器分发／迭代失败以及带内的终止错误或中止结束才进入 `agent/request-error`；中间件、结果处理、工具及其他扩展失败会直接关闭轮次。失败步骤关闭后，恢复逻辑会接收确切的实时错误、不可变的提供方事实、不可变的先前失败、为请求提供服务的适配器注册所对应的不可变重试策略，以及轮次信号；如果没有最终适配器为其提供服务，则该策略缺失。处理失败的监听器返回 `{ kind: 'retry' }`；循环用其错误关闭失败轮次，并在不插入空闲通知的情况下开启一个编号重试轮次。成功会清除连续失败历史；未被处理的失败是终态。AgentLoop 为当前接纳或轮次拥有一个取消信号。有效的 `cancel(cause)` 在未设置 `keepInbox` 时清除待处理工作，并以协作方式中止该信号；空闲取消是空操作。持久 `turn/end` 为 `user` 和 `parent` 记录 `aborted`，dispose（资源释放）则记录 `disposed`；未分发的模型工具调用会收到合成的 `tool/call` 与 `ABORTED_BEFORE_DISPATCH` 结果对。取消原因只改变报告方式，不改变对取消后已定案结果上下文的处理。dispose 会等待忽略信号的工作完成，然后才从注册表移除。[显式取消决策](../../../.agents/notes/implemented/architecture/2026-07-16-explicit-turn-cancellation.md)规定生命周期与竞态契约。 @@ -89,7 +89,7 @@ interface Config { #### Token 影响 -每个步骤都会再次计入系统文本与 schema。逐 agent 作用域决定贡献，而权威组装 waterfall（瀑布式事件）可以改变最终请求，并使其监听器负责保持协议连贯。 +每个步骤都会再次计入系统文本与 schema。逐 agent 作用域决定贡献，而权威组装 waterfall 可以改变最终请求，并使其监听器负责保持协议连贯。 #### KV Cache 影响 diff --git a/packages/core/agent-loop/src/agent.ts b/packages/core/agent-loop/src/agent.ts index 9c930912ba..65f3fe4b2a 100644 --- a/packages/core/agent-loop/src/agent.ts +++ b/packages/core/agent-loop/src/agent.ts @@ -487,24 +487,21 @@ export class ReactLoopAgent implements Agent { const assembler = new BlockAssembler() const chunkSeqs: number[] = [] - const onDispatched = (): void => { - emitAgentEvent( - this.loopCtx, - this, - 'agent/model-request', - turn, - step, - { - provider: request.provider, - model: request.model, - ...preparedCall?.context === undefined - ?

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 4e52058c17..400031b7d6 100644 --- a/packages/host/apiproxy/README.zh.md +++ b/packages/host/apiproxy/README.zh.md @@ -22,7 +22,7 @@ Workspace 列表与 Session 列表是相互独立的重连基线。`workspace.cr `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。 +上下文容量使用独立的临时 `session/model-request` mux 帧；观察到的请求尝试返回外层流句柄后，该帧由失败会被收容的 Agent 通知发出。这个边界不能证明提供方 I/O 已开始。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/events.ts b/packages/host/apiproxy/src/api/events.ts index c4babb6017..2eec50c257 100644 --- a/packages/host/apiproxy/src/api/events.ts +++ b/packages/host/apiproxy/src/api/events.ts @@ -60,11 +60,11 @@ export type MuxFrame = | { type: 'session/subscribed'; sessionId: SessionId; lastSeq: number } | { type: 'session/metrics'; sessionId: SessionId; metrics: SessionMetrics } /** - * One model request observed by this already-open mux connection after its - * final route and stream handle were resolved.

[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.

Compaction can replace visible content without preserving historical usage. Conversely, context occupancy describes one real request boundary: a selected model is only an intention, and combining token pressure from one moment with capacity resolved for another route creates a false percentage. + +These two values therefore have different lifetimes. Provider-reported billing is durable, replayable session state. Request pressure and registration-bound capacity are an opportunistic live observation that must disappear across a connection generation. + +## Decision + +`@deepseek-ai/dsh-token-meter` registers the generic `tokenUsage` session projection when `ctx.sessionProjections` is present. The projection folds the complete durable log into uncached input, output, cache-read, and cache-write buckets. An `assistant/chunk` usage sample survives a later failed request; an `assistant/message` usage value replaces the earlier value for the same `(turn, step)` instead of being counted twice. Reasoning tokens remain an output subdivision and are not added again. Compaction and surface replacement do not erase earlier billing. + +The projection uses the standard projection lifecycle and wire path. History tail baselines, `session/projection` live frames, higher-seq-wins client storage, JSON checkpoints, cache recovery, and unit unload all remain generic. There is no token-specific history field, mux frame, projector, revision counter, or client fence. + +`LlmService.prepareCall()` retains context metadata from the exact lookup that also validates reasoning and captures the adapter registration. After the outer stream call returns its handle and before iteration begins, AgentLoop emits one contained `agent/model-request` notification. Preparation or a synchronous outer waterfall failure emits nothing; short-circuit handles and later iterator construction, iteration, or abort failures still count as an observed request attempt. + +ApiProxy handles that notification synchronously. 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`. It broadcasts one atomic `session/model-request` frame containing the route, turn, step, and whichever of `contextTokens` and `contextWindow` are available. Measurement failure omits only the numerator. The frame goes only to mux connections already open at that instant; history, subscription baselines, reconnect, and restore never replay it. + +The client stores the complete latest request frame as `ConversationSnapshot.modelRequest`. Every later frame replaces the entire snapshot, so omitted fields clear earlier values. `SessionManager` temporarily holds a pre-instantiation frame, while a new subscription generation, disconnect, or session removal clears both resident and pending values. Model selection alone does not change this snapshot. + +The Web `StatsLine` reads `tokenUsage` through the standard `useProjection` hook and reads request telemetry plus visible nodes through `useSession`. It renders uncached input, output, and cache reads separately, computes cache hit as `cacheRead / (uncachedInput + cacheRead)`, and shows context occupancy only when one request snapshot contains both numerator and capacity. Visible nodes continue to supply only turn and step counts. The existing inline text UI is retained; the model selector gains no circle or other accessory. + +## Alternatives considered + +**A custom session metrics history field and mux frame.** This duplicated the generic projection protocol, cache, recovery, and seq fencing while coupling durable billing to transient request pressure. + +**Fold the loaded node window in React.** This cannot survive pagination or compaction and makes a presentation package reconstruct log semantics. + +**Publish usage only with final assistant messages.** A request that reports a usage chunk and then fails would lose provider billing. + +**Query capacity from the selected model.** Selection may never produce a request, and a second metadata lookup can disagree with the registration-bound lookup used by the actual call. + +**Persist or replay the latest request snapshot.** A request from a prior connection would appear current after restore even though no new request was observed. + +**Add a context circle beside the model selector.** That placement suggests selected-model state.

Context occupancy is deliberately unknown after reconnect until a new real request is observed. Deployments without token-meter or without model capacity still publish the request route and clear stale optional fields instead of fabricating a percentage. + +ApiProxy performs one synchronous optional measurement and one frame conversion per observed request. It owns no per-session metrics cache or refresh queue. The browser keeps one generic projection value plus one small connection-local request snapshot, and streaming text deltas do not force the stats line to recompute. diff --git a/.agents/notes/implemented/architecture/2026-07-29-projected-token-usage-and-request-context.zh.md b/.agents/notes/implemented/architecture/2026-07-29-projected-token-usage-and-request-context.zh.md new file mode 100644 index 0000000000..02b03d1516 --- /dev/null +++ b/.agents/notes/implemented/architecture/2026-07-29-projected-token-usage-and-request-context.zh.md @@ -0,0 +1,45 @@ +# Agent Note：token 用量投影与请求上下文 + +Status: implemented + +[English](2026-07-29-projected-token-usage-and-request-context.md) | 中文 + +## 问题 + +Web 统计行若根据当前已加载的会话节点推导，其结果会在分页时依赖当前窗口。压缩（compaction）可以替换可见内容，却不保留历史用量。另一方面，上下文占用率描述的是一个真实请求边界：所选模型只代表意图；若把某一时刻的 token 压力与另一路由解析出的容量组合，就会产生虚假百分比。 + +因此，这两个值具有不同的生命周期。提供方报告的计费用量属于持久、可回放的会话状态。请求压力和与注册项绑定的容量则是恰好可得的实时观测，跨连接代次时必须消失。 + +## 决策 + +当 `ctx.sessionProjections` 存在时，`@deepseek-ai/dsh-token-meter` 会注册通用的 `tokenUsage` 会话投影。该投影将完整持久日志归并为未缓存输入、输出、缓存读取和缓存写入四类计数项。即使后续请求失败，`assistant/chunk` 用量样本仍会保留；同一 `(turn, step)` 的 `assistant/message` 用量值会替换先前值，不会重复计数。推理（reasoning）token 仍是输出的细分项，不会再次累加。压缩和表层替换不会抹除先前的计费用量。 + +该投影使用标准的投影生命周期与协议路径。历史尾页基线、`session/projection` 实时帧、seq 高者胜的客户端存储、JSON 检查点、缓存恢复和单元卸载均保持通用机制。系统没有任何 token 专用的历史字段、mux 帧、投影器、修订计数器或客户端 seq 防护机制。 + +`LlmService.prepareCall()` 会保留精确查询得到的上下文元数据；同一次查询还会校验推理强度并捕获适配器注册项。外层流调用返回句柄后、开始迭代前，AgentLoop 会发出一条失败受收容的 `agent/model-request` 通知。准备阶段或外层 waterfall（瀑布式事件）的同步失败不会发出通知；短路句柄以及之后的迭代器构造失败、迭代失败或中止仍算作一次已观测的请求尝试。 + +ApiProxy 会同步处理该通知。当可选服务存在时，它会读取一次 `tokenMeter.measure(agent.session).totalTokens`，并将结果与同一准备完成调用中绑定注册项的 `contextWindow` 合并。它会广播一个原子 `session/model-request` 帧，其中包含路由、轮次、步骤，以及可用的 `contextTokens`／`contextWindow` 字段。测量失败时只省略分子。该帧只发送给当时已经打开的 mux 连接；历史记录、订阅基线、重连和恢复都绝不回放该帧。 + +客户端将最新的完整请求帧存储为 `ConversationSnapshot.modelRequest`。每个后续帧都会替换整个快照，因此省略字段会清除先前值。`SessionManager` 会临时保存一个实例化前帧；新订阅代次、断开连接或移除会话时，则会同时清除常驻值和待处理值。仅选择模型不会改变该快照。 + +Web `StatsLine` 通过标准 `useProjection` 钩子读取 `tokenUsage`，并通过 `useSession` 读取请求观测数据与可见节点。它分别显示未缓存输入、输出与缓存读取，通过 `cacheRead / (uncachedInput + cacheRead)` 计算缓存命中率，并且只有同一份请求快照同时包含分子与容量时才显示上下文占用率。可见节点仍只提供轮次和步骤计数。系统保留现有的行内文本 UI；模型选择器不增加圆环或其他附属控件。 + +## 备选方案 + +**自定义会话指标历史字段和 mux 帧。** 这会重复实现通用投影协议、缓存、恢复和 seq 防护机制，并将持久计费用量与临时请求压力耦合。 + +**在 React 中归并已加载的节点窗口。** 此方案无法跨分页或压缩保留数据，还会迫使展示包重建日志语义。 + +**仅随最终 assistant 消息发布用量。** 如果请求报告一个用量分片后失败，就会丢失提供方计费用量。 + +**从所选模型查询容量。** 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调用所用的、绑定注册项的查询不一致。 + +**持久化或回放最新请求快照。** 即使没有观察到任何新请求，先前连接的请求也会在恢复后显得仍是当前请求。 + +**在模型选择器旁增加上下文圆环。** 该位置会让人以为这是所选模型的状态。现有统计行可以表达按请求作用域的语义，无需引入重复的 UI 或数据路径。 + +## 后果 + +token 总量在分页、压缩、回放和重连期间保持稳定，因为它们属于普通的持久投影状态。重连后，上下文占用率会刻意保持未知，直到系统观察到新的真实请求。未部署 token-meter 或模型不提供容量时，系统仍会发布请求路由，并清除陈旧的可选字段，而不会虚构百分比。 + +ApiProxy 会为每次已观测请求执行一次可选的同步测量和一次帧转换。它不拥有任何逐会话指标缓存或刷新队列。浏览器只保留一个通用投影值和一个小型连接本地请求快照；流式文本增量不会迫使统计行重新计算。 diff --git a/apps/web/tests/question-composer.e2e.ts b/apps/web/tests/question-composer.e2e.ts index 6ecdb683b3..8689a74fc2 100644 --- a/apps/web/tests/question-composer.e2e.ts +++ b/apps/web/tests/question-composer.e2e.ts @@ -104,7 +104,7 @@ describe('web e2e: resident question composer round trip', () => { const inner = child.getBoundingClientRect() return Math.max(box.top - inner.top, inner.bottom - box.bottom) }))) - const list = rows[0]?.parentElement ?? null + const list = card.querySelector('[data-question-scroll]') return { rows: rows.length, spill: Math.max(...spill), diff --git a/apps/web/tests/snapshots/code-mode-round/ui.expected.md b/apps/web/tests/snapshots/code-mode-round/ui.expected.md index 4847924619..dccd3fd7dc 100644 --- a/apps/web/tests/snapshots/code-mode-round/ui.expected.md +++ b/apps/web/tests/snapshots/code-mode-round/ui.expected.md @@ -12,6 +12,7 @@ - img - button "编辑": - img +- button "▸ 上下文注入" - 'button "Think The user wants me to write a single `run_code` program that:"': - img - img @@ -28,7 +29,7 @@ - img - text: Think The program ran successfully.

Model selection alone does not alter request telemetry. ## Workspace and Session lists diff --git a/packages/client/runtime/README.zh.md b/packages/client/runtime/README.zh.md index 1b1d7f03d1..873fefca48 100644 --- a/packages/client/runtime/README.zh.md +++ b/packages/client/runtime/README.zh.md @@ -2,7 +2,7 @@ [English](README.md) | 中文 -客户端 cordis 启动与不依赖 React 的对象服务：SlotsService 包装 SlotCore 并提供 renderer 数据源；SessionsService 拥有 Session 对象、列表／scope／history 状态；WorkspacesService 依赖 SessionsService，拥有 Workspace 对象、列表／操作、默认目标派生，以及 New Session 空会话复用入口（`connectWorkspace`）。运行时把共享 Host 流分发给两个 manager。客户端 Session 一律由 Host 出生（一次 `session.create` 同瞬产出 Session+Agent+cwd）；客户端不持有任何实体化之前的会话状态——Agent scope（host dsh-scope 的客户端镜像，以 agent/session 共用 id 为键）在会话行进入列表镜像时出生，随 prune 死亡。契约：api-contracts v3 §4。每个 `Session` 持有一个通用的 `ProjectionValueStore`，由历史尾页的 `projections` 块播种，并经 `session/projection` 帧按 seq 高者胜更新；领域键（含 `todos` 与 `title`）经 `projections.faceOf`／`useProjection` 读取，不经 `ConversationSnapshot`。持久的 `ConversationSnapshot.metrics` 则来自独立的 history 尾页值与实时 `session/metrics` 帧，因为即时 token-meter 压力可以在相同持久日志修订号上继续变化；客户端只接受日志修订号与投影修订号均不减小的数据。`ConversationSnapshot.modelRequestContextWindow` 另行保留当前 mux 连接观察到的最新 `session/model-request` 容量。后续请求会替换或清除该值，`session/subscribed` 则同时清除指标顺序状态与容量；因此，重连、恢复和新订阅都不会显示百分比，直到观察到另一次请求。缺失的 metrics 保持为 `null`，而不是根据可见节点窗口推断。 +客户端 cordis 启动与不依赖 React 的对象服务：SlotsService 包装 SlotCore 并提供 renderer 数据源；SessionsService 拥有 Session 对象、列表／scope／history 状态；WorkspacesService 依赖 SessionsService，拥有 Workspace 对象、列表／操作、默认目标派生，以及 New Session 空会话复用入口（`connectWorkspace`）。运行时把共享 Host 流分发给两个 manager。客户端 Session 一律由 Host 出生（一次 `session.create` 同瞬产出 Session+Agent+cwd）；客户端不持有任何实体化之前的会话状态——Agent scope（host dsh-scope 的客户端镜像，以 agent/session 共用 id 为键）在会话行进入列表镜像时出生，随 prune 死亡。契约：api-contracts v3 §4。每个 `Session` 持有一个通用的 `ProjectionValueStore`，由历史尾页的 `projections` 块播种，并经 `session/projection` 帧按 seq 高者胜更新；领域键（含 `todos`、`title` 与 `tokenUsage`）经 `projections.faceOf`／`useProjection` 读取，不经 `ConversationSnapshot`。`ConversationSnapshot.modelRequest` 另行保留当前 mux 连接观察到的最新完整 `session/model-request`。每个帧都会替换整个快照，因此分子或容量字段一旦缺失，就会清除先前值。`SessionManager` 会缓冲一个实例化前快照；`session/subscribed`、断开连接和移除会话则会清除常驻值与待处理值；因此，重连、恢复和新订阅都不会显示上下文百分比，直到观察到另一次请求。仅选择模型不会改变请求观测数据。 ## Workspace 与 Session 列表 diff --git a/packages/client/runtime/src/client/sessions/conversation.ts b/packages/client/runtime/src/client/sessions/conversation.ts index 78ec9e2cd8..f211b209fd 100644 --- a/packages/client/runtime/src/client/sessions/conversation.ts +++ b/packages/client/runtime/src/client/sessions/conversation.ts @@ -6,7 +6,7 @@ import type { CommandId } from '@deepseek-ai/dsh-commands/brand' import type { ContentBlock } from '@deepseek-ai/dsh-llm/types' import type { - RpcError, SessionId, SessionMetrics, ToolCallView, ToolResultView, + ModelRequestTelemetry, RpcError, SessionId, ToolCallView, ToolResultView, } from '@deepseek-ai/dsh-client-connection/client' import type { PendingInteraction } from './pending.ts' @@ -267,16 +267,6 @@ export interface ConversationSnapshot { */ blank: boolean lastAgentError: string | null - /** - * Host-owned cumulative usage/current pressure.

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;

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).

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.

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.

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. 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.

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.

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).

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.

 {"type":"request/header","seq":4,"time":1783957884486,"data":{"header":{"config":{"provider":"deepseek","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.

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.

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.

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.

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.

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.

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 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.

 - **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.

+The single owner of sandbox-policy resolution: the deployment's default [`SandboxMode`](../sandbox/README.md) and fallback root, plus each session's durable mode override and immutable workspace root. Every enforcing family receives one resolved mode-and-root policy per call and registers whether the current runtime fences filesystem tools, one-shot bash commands, or terminal sessions; the model receives only those current facts before each request.
 
 ## 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.

 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.

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.

 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。

 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。

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. 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.

Subject: [PATCH 046/101] 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.

 `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).
 
+## 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 banner summary folds the pre-cap total in when the tool capped the result (`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 result as complete; a copy control writes the whole structured result regardless of the cap or which groups are collapsed. Geometry mirrors CodeBlock/TerminalBlock. Rationale: [the web search card note](../../../.agents/notes/implemented/feature/2026-07-30-web-search-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)。
 
+## 搜索结果
+
+`SearchBlock` 渲染一次已完成的搜索,一个组件绘制两种 kind(由 `kind` 判别)。`matches`(grep)把每个文件渲染为粗体路径头加其 `lineNumber: line` 行,每个文件组可折叠;`paths`(glob)渲染扁平路径列表。两者都摊平成一个行列表,由高度上限做头/尾切片(默认 16,与 TerminalBlock 相同的切分算法),且都不软换行——长匹配行或路径横向滚动而非折行。当工具截断结果时,banner 摘要把截断前总数折入(grep 为 `显示 X / 共 N 处匹配 · K 个文件`,glob 为 `显示 X / 共 N 个路径`),使卡片绝不把截断结果呈现为完整;复制控件写入完整结构化结果,无论是否触及上限或哪些组被折叠。几何镜像 CodeBlock/TerminalBlock。原理:[Web 搜索卡片笔记](../../../.agents/notes/implemented/feature/2026-07-30-web-search-card.md)。

Subject: [PATCH 048/101] fix(web-search-card): surface result text when an
 errored search has no card
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

grep/glob return no presentResult on an error result, so an errored search had
no card and the keyed SearchRow showed only a red dot — the model-facing error
text (bad pattern, missing path, a nested run_code dispatch with no card) was
nowhere on screen. Add an error-text arm mirroring the file-mutation and read
rows. Added tests for the text arm and its name/code fallback. The unknown-kind
fallback in search-card-model is already guarded (returns null → generic path).

Subject: [PATCH 050/101] perf(web-read-card): lazy-load read grammars and
 guard empty-window copy

Only TypeScript, shell, and JSON grammars load at Web boot; the read card's
wider langFromPath extension set loads through dynamic imports on first use,
so a session that never opens a read card in one of those languages avoids
~1.6 MB of grammar modules and their synchronous init. ReadBlock/CodeBlock
re-render on grammar-load via useSyncExternalStore, picking up highlighting
once the grammar registers. ReadBlock hides the copy control on an empty
window (a successful read of an empty file settles to lines: [] with
card:'read'), matching TerminalBlock so it cannot wipe the clipboard.

 Whole-row collapse/expand (defaulting every tool call to collapsed) is a separate later change that will flip every resident card at once; this note's card is resident, matching the terminal card it sits beside.
 
+**Read-card grammars load lazily; only the boot three stay eager.** `highlight.ts` is a platform seed `ui-primitives` loads on every Web boot, and its warm-up unconditionally builds the shiki singleton. 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. It is ordered before the todo turn (now 67) for the same reason the terminal sample is: the standing plan retires at the next `turn/start`.

+**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）。

 **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。

Subject: [PATCH 051/101] 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.

-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.

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

 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. 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. Keyless replay owns the neutral denial-to-escalation trajectory; it is a structural regression proof, not wording-selection evidence.

+

 **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。

 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).

 - `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.

 - `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.

+### 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.

 - `renderPrompt(assembly)`：插值每个段中的 `{{variable}}` 引用，删除空段，并用空行连接。严格规则：未知引用（使用 `Object.hasOwn` 查找，因此 `{{constructor}}` 等原型名称未知）、已注册但无值的引用、格式错误的完整 `{{…}}` 组，或一个起始 `{{` 没有打开完整组、但后面仍有 `}}`（`{{{model}}}`），都会抛出；明确失败胜过交付格式错误的提示词。孤立的 `{{` 如果后面任何位置都没有 `}}`，会按字面量通过；替换值绝不再次扫描。
+- `renderContextSnapshot(assembly)`：对上下文执行同样严格的插值，删除空条目，并发出一份带显式取代声明的完整快照。活动集合为空时返回 `''`；先前可见的上下文消失时，循环会发出一份清除快照。
 
 可通过合并扩展：插件可以借助声明合并，为 `PromptAssembly` 和 `AssembleContext` 声明额外字段。
 
 ### 扩展点
 
 - 段提供方：工具包（package）拥有跨调用引导（`tool:bash`、`tool:read` 等）；此插件拥有 `harness:identity` 与 `deployment:persona`。
-- 变量提供方：agent loop（智能体循环）注册 `model` 与 `cwd`；任何插件都可以注册自己拥有的事实（未来的 `date`、git 状态等）。
+- 上下文提供方：策略及其他变化状态的归属方贡献完整的当前事实，而不改变稳定的系统提示词。
+- 变量提供方：agent loop 注册 `model` 与 `cwd`；任何插件都可以注册自己拥有的事实（未来的 `date`、git 状态等）。
 - 工具 schema 提供方：`ToolRegistry` 自动将自身注册为工具提供方。
 - [`system-prompt/assemble` waterfall](#live-events)：按调用方协作式修改或替换组装结果。

+活动上下文经过严格插值后按确定顺序连接，并在首次需要该快照的请求之前立即记录为一条带来源的 user 角色消息。消息以 `Current runtime context. This snapshot supersedes earlier runtime-context snapshots.` 开头。变化后的快照会追加到保留的历史之后；保留的快照未变时不会增加内容。如果压缩移除了它，当前完整快照会再次发出。移除最后一项上下文时会发出一份显式清除快照。

 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.
 
+When `ctx.fs.sandboxMode` reports confinement, write/edit advertise `sandbox_permissions` and `justification`, resolve approved retries through `ctx.approval`, and register `filesystem` as escalatable with `ctx.sandboxPolicy`. The policy owner therefore adds anti-refusal context only while the real mutation tools offer that path.

 ## `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` 发后即忘
 
 `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。

+`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.

 ## 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

-
+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.

+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). 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.

Triggers on 'create figure', 'plot data', 'generate figure', 'thesis figures', 'insert figures into Word'.\n- `research-gemini-review`: Use after Claude writes any thesis prose draft — invokes Gemini API as an independent cross-model critic to eliminate self-preference bias. REQUIRED after research-writing-brief produces prose and before research-three-stage-review can be considered final. Triggers on 'review this draft', 'cross-model review', 'Gemini check', 'independent review of thesis prose'.\n- `research-hub`: Operate research-hub workflows for literature discovery, source ingest into Zotero/Obsidian/NotebookLM, dashboard inspection, and vault maintenance. Use when the user asks to find papers and organize them, build a knowledge base, ingest a folder of PDFs, upload to NotebookLM, generate research briefs, inspect clusters, or maintain a research vault. NOT for auditing or cleaning up an existing Zotero library — that's `zotero-library-curator` (read-only audit) plus `zotero-skills` (for CRUD).\n- `research-hub-multi-ai`: Research-domain router that writes `.coord/multi_ai_plan.md` when a single round of work will need two or more delegates AND the work touches research-hub artifacts (`.research/`, `.paper/`, Zotero/Obsidian/NotebookLM pipelines). For a single delegate, use `codex-delegate` or `gemini-delegate` directly — do not invoke this skill. For generic non-research multi-agent decomposition (pure code refactor, generic translation, no research-hub artifact), use `agent-collab-workspace:agent-task-splitt...\n- `research-paper-adaptation`: Use when converting a published paper (where researcher is author) into a thesis chapter — adaptation protocol with side-by-side verification and change classification. Triggers on 'adapt paper', 'paper to thesis', 'convert publication', 'published paper chapter', 'adapt manuscript'.\n- `research-postmortem`: Use when a thesis draft is rejected and must be rewritten from scratch — structured 5-part investigation into process failure with root cause analysis and systemic action items. Triggers on 'draft rejected', 'rewrite from scratch', 'writing failure', 'postmortem', 'what went wrong with the draft'.\n- `research-pre-writing-discussion`: Use before creating a Writing Brief for any thesis section — structured interview to extract researcher's knowledge, judgments, and decisions through three phases. Triggers on 'discuss section', 'plan what to write', 'pre-writing discussion', 'before writing brief', 'extract knowledge for section'.\n- `research-project-orienter`: Read the .research/ manifest files at a project root and produce a single orientation memo (research question, datasets, current stage, key entrypoints, evidence artifacts, open questions). 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. Use when asked to audit, profile, debug, or optimize page load performance, Lighthouse scores, or site speed.

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.

 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.
 
-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 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.
 
-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.

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.

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.

 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.

 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。

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.

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.

 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 057/101] 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.

 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.

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.

 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。

 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 058/101] 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 059/101] 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.

 - **截断指示。** `truncated` 时，横幅摘要把截断前总数折入 —— grep 为 `显示 X / 共 N 处匹配 · K 个文件`，glob 为 `显示 X / 共 N 个路径` —— 因此卡片绝不把一个被截断的页面呈现为完整结果。未 `truncated` 时摘要是一个朴素的结构计数（`{n} 处匹配 · {m} 个文件`，或 `{n} 个路径`）。
-- **被截断结果的恢复脚注。** 卡片只持有保留的那一页，但通往其余部分的定位符 —— grep/glob 的 `Full … stored at: ` 脚注 —— 只存在于结果视图的 `content` 文本里，而非结构化的 matches/paths 中。由于每个渲染点都用卡片替换了原始结果，`searchCardModel` 在（且仅在）结果被截断时把压平后的 `content` 作为 `SearchCardModel.recovery` 暴露出来，每个渲染点把它画在卡片下方。没有它，通往被丢弃行的唯一路径就会从 UI 里消失；未截断的结果携带了每一行，其 `content` 不增加任何信息，因此被丢弃。
+- **被截断结果的恢复脚注。** 卡片只持有保留的那一页，但通往其余部分的定位符 —— grep/glob 的 `Full … stored at: ` 脚注 —— 只存在于原始 `tool/result` 内容里（搜索视图不携带结果文本；没有卡片的 UI 回退到那段原始内容），而非结构化的 matches/paths 中。由于每个渲染点都用卡片替换了原始结果，`searchCardModel` 在（且仅在）结果被截断时把 block 自身压平后的结果文本作为 `SearchCardModel.recovery` 暴露出来，每个渲染点把它画在卡片下方。没有它，通往被丢弃行的唯一路径就会从 UI 里消失；未截断的结果携带了每一行，其原始文本不增加任何信息，因此被丢弃。
 - **不软换行。** 结果行在一个横向滚动的盒子里 `white-space: pre`，因此一条长匹配行或一个深路径横向滚动而不折叠。
 - **带展开控件的高度上限。** 超过 `DEFAULT_SEARCH_MAX_LINES`（16）行时显示一个头/尾切片，中间一个按钮报告被隐藏的行数，形状和算术与 `TerminalBlock` 相同。
 - **复制。** 复制控件写入整个结构化结果 —— 每个文件与匹配，或每个路径 —— 无关高度上限或哪些组被折叠，因此剪贴板携带的是结果本身，而不是卡片此刻恰好显示的内容。

Subject: [PATCH 060/101] 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.

 Renaming the seam's plugin id is now a compile error in the client: `TS2322: Type '"compact"' is not assignable to type '"compaction"'`. The import must stay **type-only** — a value import of any `@deepseek-ai` package that is neither a platform module nor an inline-safe wire layer is rejected by the client purity gate (`packages/client/tsdown.client.ts`), whose own message records that type-only imports are erased and never reach it. A type-only leaf import needs both a `tsconfig.base.json` `paths` entry and `{"path": "../../compact/compact"}` in `packages/client/runtime/tsconfig.json` `references`: composite `rootDir` rules apply to erased imports as well, and without the reference the diagnostic is `TS6059`/`TS6307`.
 
-`packages/client/runtime/tests/compact-checkpoint-pin.spec.ts` stays as the behavioral half, driving the adapter with a checkpoint built from the canonical **value**. It runs in the client **test** program, which may value-import the root; a `packages/client/*` package program may not.
+`packages/client/runtime/tests/compact-checkpoint-pin.spec.ts` stays as the behavioral half, driving the adapter with a checkpoint built from the canonical **value**. The test value-imports the cordis-free `@deepseek-ai/dsh-compact/checkpoint` leaf and deliberately never loads the compact package root or the host-side `Context` merges reachable through it.
 
 The divergence from the terminal is therefore narrow: both frontends recognize a checkpoint from the same declaration — the terminal value-imports `isCompactCheckpointSource` host-side, where no gate applies, and the client pins the type.

 重命名缝隙的插件 id 现在会在客户端产生编译错误：`TS2322: Type '"compact"' is not assignable to type '"compaction"'`。该导入必须保持**仅类型**——任何既非平台模块又非 inline-safe wire 层的 `@deepseek-ai` 包值导入都会被客户端纯度门禁（`packages/client/tsdown.client.ts`）拒绝，而它自己的报错信息就记录着仅类型导入会被擦除、永不抵达该门禁。仅类型的叶子导入同时需要 `tsconfig.base.json` 的一条 `paths` 条目和 `packages/client/runtime/tsconfig.json` `references` 中的 `{"path": "../../compact/compact"}`：composite 的 `rootDir` 规则同样适用于被擦除的导入，缺少该引用时的诊断是 `TS6059`/`TS6307`。
 
-`packages/client/runtime/tests/compact-checkpoint-pin.spec.ts` 作为行为侧的另一半保留，用由权威**值**构造的检查点驱动适配器。它运行在客户端**测试**程序中，那里可以值导入包根；`packages/client/*` 包工程不可以。

 因此与终端的分歧很窄：两个前端都从同一份声明识别检查点——终端在宿主侧值导入 `isCompactCheckpointSource`（那里不适用任何门禁），客户端钉住类型。

@@ -8,8 +8,8 @@ Four layers, importable separately:
 
 - **`launchAcpTestAgent` (launcher)** — boots a source agent under tsx or a built `lib` agent under plain Node from a supplied cwd, connects the SDK client over a raw-byte stdout tee, collects session updates and stderr, surfaces asynchronous spawn failures through startup, fails closed on unhandled permission requests, and owns graceful or signalled shutdown. Shutdown waits for process exit, inherited stdio closure, and ACP parser exhaustion before resolving or propagating a child error, so captures are complete and callers can remove owned paths after either outcome. When Windows accepts forced termination but publishes its exit marker asynchronously, shutdown gives that marker a bounded grace before treating fallback refusal as a second failure. Snapshot and ordinary e2e suites share this process boundary; a test supplies only agent paths, cwd, environment overrides, and any permission policy.
 - **`runScenario` (harness)** — drives ACP JSON-RPC stdio from a deterministic `input.json` script through the launcher, tees raw stdout for the expected-output and purity checks, and harvests every persisted raw JSONL session log (parent and subagent children, primary-first) after graceful stdin EOF. `AgentUnderTest` supplies absolute `binScript`, optional `libBinScript`, `configPath`, and `tsconfigPath` paths because the subprocess cwd is outside the repo; `workspaceParent` may move the generated child cwd from the platform temp directory when that grant is itself under test. Startup failures preserve captured agent stderr in the rejected diagnostic.
-- **Normalizers** — pure functions turning captured surfaces into stable text or portable fixtures: `normalizeStdout` (JSON-RPC ids → first-seen sequence; UUIDs and every native/JavaScript filesystem spelling of the generated cwd → tokens, longest-first; cwd-rooted separators selected as canonical `/` or host-native; doubles as the stdout-purity check), `normalizeSessionLog` (times zeroed, `seq` kept, the same cwd-path policy), `tokenizeSessionFixtureCwd` (the generated workspace and its filesystem aliases → `{{cwd}}`, authored temp paths unchanged), `scrubSystemPrompts` (prompt text → `{{system}}`), `scrubToolSchemas` (schema bulk → `{{tools}}`), and `scrubRequestHeaders` (all header bulk → `{{system}}`/`{{tools}}`/`{{messagePrefix}}` outside each pin, structure kept — [pinned-header Agent Note](../../../.agents/notes/archived/testing/2026-07-06-pin-request-header-content-in-one-scenario.md)).
-- **`defineAcpSnapshotSuite` (factory)** — registers the whole describe/it tree for a scenario table: per-scenario expected-output and re-persisted-log comparisons, record/refresh fixture write-back, rejection of structured `UNKNOWN_TOOL` results, a tokenized pin per header class composed with independently shared `system-prompt.expected.md` and `tool-schemas.expected.json` sidecars, and a live uniformity guard. Its fixture guards reject orphan scenario dirs, missing files, multiple pins for one class, duplicate sidecar content, unscrubbed JSONL headers, and malformed pinning headers. Refresh evaluates fresh leaves with the harvested run's ids, cwd, and every cwd alias, then reuses normalized-equivalent leaves only when the complete logical-record layout aligns and volatile string replacements form a bijection; ambiguous logs keep fresh strings, and fresh semantic values remain authoritative. It also expands packed timing envelopes before aligning event times, so switching between packed and unpacked layouts cannot shift later records. A newly inserted `session/title` receives its preceding event's time so feature-driven insertions do not churn the remainder of a fixture. Each scenario directory's `session.jsonl` plus contiguous `session..jsonl` siblings are the ordered primary/child inventory; the scenario table does not duplicate their count. Must be called at vitest collection time.

 Committed session fixtures use canonical packed rows. An in-flight branch that merges this contract runs the [temporary repository migrator](../../../scripts/migrate-packed-session-fixtures.ts) with `pnpm run migrate:packed-session-fixtures`; its [removal proposal](../../../.agents/notes/proposed/process/2026-07-26-remove-packed-session-fixture-migrator.md) owns deletion after affected branches converge.

 - **`launchAcpTestAgent`（启动器）**：从指定 cwd 在 tsx 下启动源 agent，或在普通 Node 下启动已构建 `lib` agent；通过原始字节 stdout tee 连接 SDK 客户端，收集会话更新和 stderr，在启动过程中公开异步 spawn 失败，对未处理权限请求快速失败，并负责优雅或带信号关闭。关闭会等待进程退出、继承 stdio 关闭和 ACP parser 耗尽，然后才解析或传播子级错误，使捕获内容完整，且调用方可在任一结果后移除自有路径。当 Windows 接受强制终止但异步发布退出标记时，关闭会给该标记有界宽限，然后才将回退拒绝视为第二次失败。快照和普通 e2e 套件共享该进程边界；测试只需提供 agent 路径、cwd、环境覆盖和任何权限策略。
 - **`runScenario`（harness）**：通过启动器从确定性 `input.json` 脚本驱动 ACP JSON-RPC stdio，将原始 stdout tee 给预期输出和纯度检查，并在优雅 stdin EOF 后收集每个持久化原始 JSONL 会话日志（父级和 subagent 子级，主级优先）。`AgentUnderTest` 提供绝对 `binScript`、可选 `libBinScript`、`configPath` 和 `tsconfigPath` 路径，因为子进程 cwd 位于仓库外。当生成子级 cwd 自身位于待测授权中时，`workspaceParent` 可以将它从平台临时目录移出。启动失败会在拒绝诊断中保留已捕获 agent stderr。

 `dsh-sandbox-policy`, the owner of mode and workspace-root resolution, registers one `sandbox:policy` cache-safe context contribution. Every agent request resolves the active session directly through `ctx.sandboxPolicy.resolve({ session })`; there is no denial-history scan or process-local “last told” state.
 
-Enforcing backends register independently disposable `filesystem`, `bash`, or `terminal` family contributions with the policy owner. The contribution 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 policy contribution is capability-neutral and present for every agent session. It does not maintain a second inventory of mounted backends or tools; model-visible schemas remain the authority for available operations, while the context conditions its claims on any available operation that the DSH file sandbox enforces. The [capability-neutral policy context decision](../simplification/2026-07-31-capability-neutral-sandbox-policy-context.md) supersedes the earlier family-registration mechanism while retaining this note's cache-safe delivery and durable snapshot design.
 
-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 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.

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.

 **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. 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. 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.

+# Agent Note: Capability-neutral sandbox policy context
+
+Status: implemented
+
+English | [中文](2026-07-31-capability-neutral-sandbox-policy-context.zh.md)
+
+## Problem
+
+The current-policy context originally mirrored runtime composition through separate enforced-family and escalatable-family registries. Six backend, tool, and example call sites contributed `filesystem`, `bash`, or `terminal`; the policy service retained token sets for independent disposal, intersected and ordered the two registries, invalidated prompt assemblies on every lifecycle change, and tested every family combination.
+
+That inventory was neither needed to state the file policy nor authoritative for model-visible capability. A backend contribution could name a family whose model-facing tool was absent or hidden by request scope, while tool schemas already told the model which exact operations were available. The registries therefore widened the public service and lifecycle contract to maintain an approximate English sentence.
+
+## Decision
+
+`dsh-sandbox-policy` contributes one capability-neutral `sandbox:policy` context for every agent session. It derives the text only from `resolve({ session })`; there is no backend or tool family registration API, contribution map, ordering rule, or registration-driven prompt invalidation.
+
+The text conditions capability claims on available operations that the DSH file sandbox enforces. Under `read-only`, it states that such operations cannot modify files in the standing mode and tells the model to try an available tool normally, then follow any denial and escalation guidance that tool returns. Under `workspace-write`, it states the canonical session workspace and the qualified temporary-area allowance. Under `danger-full-access`, it states that the DSH file sandbox does not restrict file modifications by available operations.
+
+Tool schemas remain the authority for which operations are available. Tool results remain the authority for operation-specific denials and approved wider retries. Filesystem, one-shot bash, and terminal implementations continue to resolve and enforce the same per-call policy; only the redundant model-facing capability inventory is removed.
+
+This decision partially supersedes the family-registration and composition-conditioned wording in [the current sandbox policy context decision](../feature/2026-07-30-current-sandbox-policy-context.md). That note remains the owner of cache-safe context delivery, durable snapshot materialization, wording evidence, and the separation between guidance and enforcement.
+
+## Alternatives considered
+
+**Keep the registries but reduce their tests.** Rejected because the public methods, retained lifecycle state, six contribution sites, and approximate capability claim would remain. The combinatorial tests reflected the design cost; they did not create it.
+
+**Derive an exact inventory from the tool registry.** Rejected because current policy needs only a truthful conditional statement, while exact availability already appears in the assembled tool schemas and can vary by request scope. Mapping each schema back to an enforcement backend would introduce another derived relation with no current consumer.
+
+**Omit policy context unless a backend advertises enforcement.** Rejected because it recreates the registration problem and makes policy visibility depend on optional contributors. The conditional wording remains truthful even when no applicable operation is available.
+
+## Consequences
+
+The policy service has one owner-derived context path instead of two public registries and their disposal lifecycle. Capability additions and removals no longer churn the runtime-context snapshot, while mode and workspace changes still do. Exact mode wording, canonical roots, switching, resume, service disposal, and no-agent assembly remain covered; family-combination and contribution-lifecycle tests disappear with the behavior they protected.
+
+The model no longer receives a prose list of sandboxed capability families. It receives exact tool schemas plus one standing file-policy statement. If a future product needs a separate capability inventory, it must be derived from the authoritative per-request assembly rather than reconstructed through backend registration side channels.

+# Agent Note: 不依赖具体能力的沙箱策略上下文
+
+Status: implemented
+
+[English](2026-07-31-capability-neutral-sandbox-policy-context.md) | 中文
+
+## 问题
+
+当前策略上下文最初通过受强制执行家族与可升权家族两个独立注册表来映射运行时组合。后端、工具与示例中的六个调用点会贡献 `filesystem`、`bash` 或 `terminal`；策略服务保留 token 集合，以便独立释放各项注册，对两个注册表的内容求交集并排序，在每次生命周期变化时使提示词组装失效，并且需要测试覆盖所有家族组合。
+
+这份清单既不是说明文件策略所必需的，也不能作为模型可见能力的权威依据。后端贡献可能声明某个家族，而该家族面向模型的工具并不存在，或被请求作用域隐藏；工具 schema 已经向模型准确说明哪些操作可用。因此，为了维护一句近似的英文说明，注册表扩大了公开服务与生命周期契约。
+
+## 决策
+
+`dsh-sandbox-policy` 为每个 agent（智能体）会话贡献一项不依赖具体能力的 `sandbox:policy` 上下文。上下文文本只根据 `resolve({ session })` 派生；不存在后端或工具家族注册 API、贡献映射、排序规则，也不会因注册变化而使提示词失效。
+
+该文本将能力声明限定于 DSH 文件沙箱所强制执行的可用操作。在 `read-only` 下，它说明这类操作在常驻模式下无法修改文件，并指示模型正常尝试可用工具，随后遵循该工具返回的任何拒绝与升权引导。在 `workspace-write` 下，它说明规范化的会话工作区，以及带有适用条件的临时区域写入许可。在 `danger-full-access` 下，它说明 DSH 文件沙箱不会限制可用操作修改文件。
+
+哪些操作可用仍以工具 schema 为准。针对具体操作的拒绝以及获批后的更宽松模式重试，仍以工具结果为准。文件系统、一次性 bash 与终端实现继续解析并强制执行相同的逐调用策略；移除的只有面向模型的冗余能力清单。
+
+本决策取代了[当前沙箱策略上下文决策](../feature/2026-07-30-current-sandbox-policy-context.md)中关于家族注册与按组合条件化措辞的部分内容。缓存安全的上下文交付、持久快照具体化、措辞证据，以及引导与强制执行之间的边界，仍以该 Agent Note 为归属文档。
+
+## 曾考虑的替代方案
+
+**保留注册表，但减少对应测试。** 不予采用，因为公开方法、保留的生命周期状态、六个贡献点和近似的能力声明仍会存在。组合测试只是体现了这一设计成本，并非成本的成因。
+
+**从工具注册表派生确切清单。** 不予采用，因为当前策略只需要一句符合事实的条件性声明，而确切的可用情况已经体现在组装后的工具 schema 中，并且可能随请求作用域变化。若再把每个 schema 映射回其强制执行后端，就会引入另一项派生关系，而当前没有消费方需要它。
+
+**仅在后端声明会强制执行时提供策略上下文。** 不予采用，因为这会重现注册问题，并使策略是否可见取决于可选贡献方。即使没有可适用的操作，这段带条件的措辞仍然符合事实。
+
+## 后果
+
+策略服务只有一条由归属方直接派生的上下文路径，无需维护两个公开注册表及其释放生命周期。增加或移除能力不再导致运行时上下文快照反复变化，模式和工作区变化仍会触发快照更新。聚焦测试仍覆盖各模式的确切措辞、规范化根目录、模式切换、恢复、服务释放与无 agent 组装；家族组合与贡献生命周期测试则随其所保护的行为一同删除。
+
+模型不再收到以自然语言列出的沙箱能力家族清单，而是收到确切的工具 schema 与一项常驻文件策略声明。未来若产品需要独立的能力清单，该清单必须从权威的逐请求组装结果中派生，不能通过后端注册这种旁路机制重建。

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. 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.

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.

 - **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. This backend also contributes the one-shot bash family to the owner-rendered current-policy section; the static bash tool description separately owns denial and escalation guidance.

 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. The policy owner contributes current standing mode and composition-conditioned anti-refusal context; denial results still own the operation-specific effective mode and retry guidance.

 ## Why a shared home
 
-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. The [cross-family fs sandbox Agent Note](../../../.agents/notes/implemented/feature/2026-07-14-cross-family-fs-sandbox.md) records the shared-policy decision.

 Each owner exports the same three-piece kit: the event declaration, a pure fold (`effectiveSandboxMode(events)` / `effectiveApprovalPolicy(events)` — a `findLast`, typed to the domain's closed union), and THE write path (`setSandboxMode(session, mode)` / `setApprovalPolicy(session, policy)` — a switch IS its event; nothing mutates state out of band). No shared owner service, no generic facts map, no registry: a third knob copies the ~40-line pattern into its own package. Execution follows the fold on both sides — the bash tool's per-call stamp reads it as the middle rung of the § Escalation precedence chain, and the approval seam's `'never'` gate is [the approval Agent Note](2026-07-06-approval-seam.md)'s side of the same pattern.
 
-Sandbox policy is rendered from the current mode and workspace root before every request; the existing `request/header` records the exact section, so no switch narrator or last-told state is needed. Approval policy stays separate: only `'never'` is stated because automatic rejection otherwise looks like a user decision, and its owner retains its own switch narration.
+Sandbox and approval policy are rendered as ordered contributions to one runtime-context snapshot before every request. The loop records the complete snapshot as a sourced `user/message`; both `'ask'` and `'never'` are explicit, so neither owner needs switch narration or last-told state.
 
 **The optional UI surface** is `PermissionService`: a deployment-defined preset table whose entries bundle one sandbox mode with one approval policy. The shipped `workspace-write` and `danger-full-access` presets write through to both domain setters; a knob combination outside the table is reported as `custom`. UI adapters may expose that table as a selector. The automation-only ACP transport advertises no configuration selector and mounts no permission-preset service.

 - **Hard-match the retry to a prior denial** — rejected: command-string identity is fragile (quoting, `workdir`, env prefixes, a pipeline retried as its failing stage) — false-rejects honest retries or is trivially satisfied; the real boundary is the human seeing command + justification. 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.

 - A denied command retried with `sandbox_permissions` + `justification` prompts the user through the composed answerer chain; a grant runs THAT call under the wider mode (result facts say so) while every other call keeps its own effective mode; every non-grant outcome produces its distinct error text and executes nothing.
 - The escalation fields exist exactly when the mounted executor confines; a request that is not strictly wider than the call's effective mode fails closed with its own text and prompts no one; a deployment with no ApprovalService fails escalating calls closed and leaves plain calls untouched.
-- The system prompt states sandbox policy and approval policy in separate owner-derived sections; the whole exchange — headers, knob events, approval notices, approvals, and results — reconstructs from the session log alone, with no event types beyond the two knob events.

 - **The model may over-ask.** Escalating without denial grounding, or picking `danger-full-access` where `workspace-write` suffices: the description steers and the enum forces the ladder, but the human prompt is the actual gate; the `approval/asked` reasons make over-asking auditable, and a `prepend` policy answerer can auto-reject patterns a deployment never wants.
 - **The advertised target set is static while the effective mode is per-session** (schemas are registry-global) — a session already at the widest mode is still offered the fields. Harmless by construction: the strict-wider check at execution, not the enum, is the safety boundary — a non-widening request fails with its own text and never prompts anyone.
 - **A granted escalation is not a working sandbox.** An unavailable backend still fails closed even for a granted escalation to a confining mode — at `confine()` when the platform has no chain or every probe fails, at execution when an unprobed sole runner refuses (classified as a sandbox failure, not a command failure) — while a granted `danger-full-access` run never touches the provider at all: there the grant, not the probe, is the authority.
-- **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.
-- **The approval and sandbox sections are dynamic prompt surfaces.** A policy switch breaks provider prompt-prefix caching for that session; unchanged state remains byte-stable, and a model acting on stale authority is worse than the bounded invalidation.
-- **The model may hold a stale belief about the sandbox mode** (nothing announces a switch). Accepted deliberately in the original design: the next attempt's marker or success corrects it, and the observed failure mode of announcing — preemptive refusal — is worse than one wasted retry.

 ## FAQ
 
@@ -191,8 +190,8 @@ Costs and accepted limits:
 - **Does the sandbox restrict network or process visibility?** No — `SandboxMode` claims FILE effects only; the bwrap profile deliberately does not unshare pid, and no backend claims network. Whether network restriction becomes its own knob is left open in § The seam.
 - **Which tools actually run confined?** OS subprocesses through `ctx.bash` — the bash tools, and hook commands transitively — plus the filesystem tools (`read`/`write`/`edit`) through the sandboxed `ctx.fs` provider (the [cross-family fs sandbox RFC](2026-07-14-cross-family-fs-sandbox.md)): bash confines via the OS runner, fs via an in-process path fence, both keying off the same `ctx.sandboxPolicy` mode. web/todo stay in-process and unfenced (web's only effect is network, outside the file-effect mode vocabulary).
 - **Does a granted escalation persist?** No. The grant is consumed by the exact foreground or background call that asked; every neighboring call keeps its own effective mode. A later background denial surfaces through `task_output` and may ground a new exact-command retry.
-- **When does a runtime mode switch take effect?** Once its session event commits, the next request section and the next capability resolution fold the new mode. The request header records what the model was told, and any later denial names the same policy at the point of use.
-- **What survives a restart — and what if the operator changed the config default while the process was down?** Overrides replay from the session log (`effective = fold ?? config`), so a resumed session keeps its modes with zero catch-up machinery; a default that drifted offline changes behavior the same way a switch does (the approval policy, being stated, is additionally narrated with operator/config attribution).

 - **What does `enforcement: 'partial'` on a result mean?** The selected backend enforces the subset its kernel ABI governs — e.g. Landlock before ABI v3 does not govern path truncate — and says so structurally instead of refusing the host; the probe's report line distinguishes the cases. The bwrap and Seatbelt profiles govern every promised file effect by construction, so they always report `full`.

 **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.

 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 and its `settings.general.item` slot, the `settings` dictionaries, and the first ordered welcome step. Feature-owned rows (Permission, 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 page preserves every authored paragraph, gives the requested clause in the final paragraph the sole emphasis, initially focuses the title, and has no close, Escape, mask-click, or secondary path. None of its copy or acknowledgement enters a Session log or model request.

A different version deliberately presents the notice again. The welcome page preserves every authored paragraph, gives the requested clause in the final paragraph the sole emphasis, initially focuses the title, and has no close, Escape, mask-click, or secondary path. None of its copy or acknowledgement enters a Session log or model request. The current draft copy retains the visible `【关闭方式待补充】` placeholder and is not release-ready until that instruction is supplied.

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 path above is the installer's default. If you set `DSH_SOURCE` or `DSH_CURRENT`, or reused an existing checkout, replace `~/.dsh/source/current` with that checkout path; see [`scripts/install.sh`](scripts/install.sh) for details.

Each composition selects the subset appropriate to its surface. The TUI and Web UI both include Plan Mode.\n\n- **Everything is a plugin.** Models, tools, policies, storage, context management, and interfaces are composable [Cordis plugins](docs/user/develop/basic/index.md), so deployments can extend or replace behavior without forking the agent loop. See the [architecture](docs/architecture.md) for the underlying design.\n- **Runs are reconstructable.** Anything visible to the model is logged in the authoritative session stream; persistence, resume/fork/query, replay, telemetry, and UIs derive from the same events.

+        "content": "# DeepSeek Harness\n\n[English](README.md) | 中文\n\nDeepSeek Harness（`dsh`）是一款基于 DeepSeek Harness SDK 构建的开源 coding agent（编程智能体）。\n\n它采用了**一切皆插件**的架构。\n\n## 内测声明\n\n感谢您愿意拨冗试用 DeepSeek Harness。当前版本仍处于内部测试阶段，功能仍待完善，体验难免有些粗糙。\n\n“如切如磋，如琢如磨。” 产品的成长，离不开一次次真实的碰撞与坦诚的反馈。您在真实使用中发现的问题，也可能促使我们重新审视，甚至推翻已有的设计。\n\n为了帮助我们更准确地还原您真实使用中的问题，内测版本默认会上传所有 Session Log；如需关闭，可以【关闭方式待补充】。另外，如果您有任何反馈与建议，请在企业微信群中留言告诉我们。每一条反馈，都会帮助我们把它打磨得更好。\n\n## 安装\n\n使用一条命令安装 `dsh`：\n\n```sh\ncurl -fsSL https://raw.githubusercontent.com/deepseek-harness/deepseek-harness/master/scripts/install.sh | sh\n```\n\n安装器要求系统已安装 `git` 和 Node `^22.19 || >=24`，缺少 `pnpm` 时可代为安装，并会提示输入 DeepSeek API 密钥。\n\n安装器会把所有检出都放在 `~/.dsh/source` 下：master 克隆位于 `~/.dsh/source/master`，每次安装的 staging 检出是一个 git worktree `~/.dsh/source/staging-<时间戳>`。稳定符号链接 `~/.dsh/source/current` 指向当前生效的 staging worktree，`~/.local/bin` 中的 `dsh` 链接到 `current/bin/dsh`，因此升级只需重指一个符号链接，PATH 上的 `dsh` 从不移动。再次运行该命令会基于更新后的 master 新增一个 staging worktree，并把 `current` 重指到它。其他安装位置和选项见 [`scripts/install.sh`](scripts/install.sh)。\n\n## 使用 DeepSeek Harness\n\n### Web UI\n\n推荐在本地使用 Web UI。安装完成后以及每次更新后，请先构建当前生效的检出，再启动 Web UI：\n\n```sh\n(cd ~/.dsh/source/current && pnpm run build)\ndsh web\n```\n\n完整构建会生成库与客户端 bundle，以及前端 dist。上述路径是安装器的默认位置。如果你设置过 `DSH_SOURCE` 或 `DSH_CURRENT`，或者复用了已有检出，请把 `~/.dsh/source/current` 换成该检出路径；详情见 [`scripts/install.sh`](scripts/install.sh)。Web UI 默认通过 `http://127.0.0.1:3080` 提供服务。\n\n### TUI\n\n启动全屏终端界面：\n\n```sh\ndsh\n```\n\n### Headless\n\n运行一项任务，打印最终答案后退出：\n\n```sh\ndsh -p \"summarize this workspace\"\n```\n\n### 自动化与 SDK\n\n在源码检出中通过环境变量或根目录 `.env` 设置 `DEEPSEEK_API_KEY`，然后启动 ACP（Agent Client Protocol）自动化服务器：\n\n```sh\npnpm run demo:acp\n```\n\n[Python SDK](python/README.md) 驱动随附的 JSON-RPC 运行时。[示例](examples/README.md)涵盖可运行的 headless、ACP、JSON-RPC、Code Mode 和自指组合。\n\n## 为什么选择 DeepSeek Harness\n\n内置功能涵盖文件读取、编辑与搜索、shell 和持久 PTY 执行、可复用 skill（技能）、任务跟踪、目标、计划、待办事项与后台任务、subagent 与工作流、沙箱与审批、设置与凭据、可持久化、恢复、fork 与查询的会话、LSP 与 Web 访问、上下文压缩（context compaction），以及遥测。每个组合只选用适合其使用方式的能力子集。TUI 与 Web UI 均包含 Plan Mode。\n\n- **一切皆插件。** 模型、工具、策略、存储、上下文管理和界面均可组合为 [Cordis 插件](docs/user/develop/basic/index.md)，部署方无需 fork agent loop（智能体循环）即可扩展或替换行为。底层设计见[架构文档](docs/architecture.md)。\n- **运行可重建。** 凡是模型可见的内容，都会记录在权威会话流中；持久化、恢复／fork／查询、回放、遥测和 UI 均从同一组事件派生。参见[会话日志架构](docs/architecture.md#session-log)。\n- **Code Mode（需显式启用）。** 它会提供 `run_code` 工具和生成的 TypeScript SDK，只有程序输出会重新进入模型上下文。参见 [Code Mode](packages/core/tools/README.md#code-mode)。\n- **自指 Cordis 工具需显式启用。** 这些工具可让 agent 检查自身的实时运行时，并在运行中挂载或卸载插件。参见 [Cordis 工具](packages/cordis/tool-cordis/README.md)。\n\n## 社区\n\n扫描二维码，或打开 DeepSeek Harness 微信社区申请页面 申请加入。\n\n

 read-card.spec workspace state

The master merge added a required archivedSessionIds field to WorkspaceListState;
the read-card spec's DetailsPanel fixture state needs it to typecheck.

 `dsh-bash-sandbox` extends `LocalBashExecutor` and hands `ctx.sandbox` the exact `['bash', '-c', command]` argv it is about to spawn. A denial is an orthogonal result fact, conservatively classified from the active runner's stderr dialect. A runner failure outranks denial: foreground execution throws `SANDBOX_UNAVAILABLE`; a settled `BashProcess` stamps `sandbox.runnerFailed`, and the bash producer renders it through generic `task_output`.
 
-The model sees the current effective file policy in the owner-derived `sandbox:policy` request section, while the static tool description explains the denial marker (`[sandbox: file access denied under  mode]`), encourages attempting commands that may be denied, and forbids retrying around a denial; when the escalation fields are advertised, a denied result additionally carries the escalation hint itself, so the sanctioned same-turn retry is prompted at the decision point rather than depending on the model recalling the description (§ Escalation).

Subject: [PATCH 089/101] feat(locale): derive the initial Settings language
 from the browser
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A first visit resolved to Chinese regardless of the browser: LocaleService
read `dsh.locale` and fell straight back to `zh` when nothing was stored,
ignoring the languages the browser already states it reads.

The initial locale now resolves through three ordered sources — the persisted
preference, then `navigator` (first entry of the ordered language list whose
primary subtag names a shipped locale, so `zh-Hans-CN` -> zh and `en-GB` ->
en), then `FALLBACK_LOCALE`. An explicit choice still wins and nothing writes
the detected locale back to storage, so "has the user chosen?" stays a
question only the stored value answers.

Specs asserting the shipped Chinese copy now state the browser they assume:
the web e2e scenarios open their page with `locale: ZH_BROWSER_LOCALE`, and
package specs pin it through the new `pinBrowserLanguages` test helper.
`settings-chrome.e2e.ts` gains an English-browser scenario as the
assembled-app proof.

+# Agent Note: The Settings language a fresh browser opens in comes from the browser
+
+Status: implemented
+
+English | [中文](2026-07-31-browser-derived-initial-locale.zh.md)
+
+## Problem
+
+The Settings Language row opened every first visit in Chinese: `LocaleService` read `dsh.locale` from localStorage and fell straight back to `zh` when nothing was stored. The browser already states which languages its user reads — `navigator.languages` is that statement — and the app ignored it, so an English reader met a Chinese product and had to find a Chinese-labelled settings row to escape it. The fallback was doing two jobs at once: the last resort for an unresolvable locale, and the answer for every user who had simply never chosen.
+
+## Decision
+
+**The initial locale resolves through three ordered sources: the persisted preference, then the browser, then `FALLBACK_LOCALE`.** `resolveInitialLocale()` in `packages/client/locale/src/client/index.ts` runs at service construction and is the only place the order is expressed; `restorePreference()` now returns `LocaleId | undefined` (an absent, unparseable, or unreachable store reads as *no preference*) so the next source can speak.
+
+**Browser matching is on the primary subtag, over the ordered list.** `detectBrowserLocale()` walks `[...navigator.languages, navigator.language]` and returns the first entry whose primary subtag names a shipped locale, so `zh-Hans-CN` and `zh-TW` both land on `zh` and `en-GB` on `en`, while a browser asking only for languages this app does not ship (`fr`, `de`) yields nothing and leaves `FALLBACK_LOCALE` in charge. `navigator.language` trails the list because a browser may expose only the former; a runtime without `navigator` at all (node booting the client tree) resolves to the fallback like any unresolvable case.
+
+**An explicit choice is permanent.** `setLocale` persistence is untouched, and the persisted value is consulted first, so a user who picked a language keeps it even when travelling between browser profiles or system languages. Nothing writes the detected locale back to storage: detection is re-derived every boot and stays invisible to the "has the user chosen?" question.
+
+**The browser e2e lane now pins the browser language, not just storage.** Scenarios asserting Chinese copy (`access-confirmation`, `models-settings`, `onboarding-deepseek-config`, `settings-chrome`) open their page with `locale: ZH_BROWSER_LOCALE` from `apps/web/tests/support.ts`; `newEnglishPage` keeps pinning `dsh.locale=en`, which still wins over any browser language. `settings-chrome.e2e.ts` gained a scenario opening a second `en-US` page with empty storage and asserting the settings surface comes up English — the assembled-app proof of this feature.
+
+## Alternatives considered
+
+- **`Intl.DateTimeFormat().resolvedOptions().locale` or a single `navigator.language` read**: both collapse the user's ordered preference list to one tag, so a `['de', 'en', 'zh']` reader gets zh instead of en. The list is the part of the browser statement worth reading.
+- **Persisting the detected locale on first boot**: it would make detection a one-time event and let a stale first visit outlive a changed browser language, and it destroys the distinction the resolution order rests on — a stored value would no longer mean "the user chose this".
+- **Full BCP 47 negotiation (`Intl.LocaleMatcher`-style lookup, region and script weighting)**: with exactly two shipped locales that differ in language, primary-subtag matching is the whole of the correct answer; a negotiation layer would be untestable surface with no behavior to justify it.
+- **A cordis config key for the default locale**: the deployment does not vary here — the fallback is the product's answer for "no signal at all", not a knob. Repo policy reserves `Config` fields for deployment-varying choices with a current consumer.
+- **Keeping the e2e lane's zh scenarios on storage pinning (`dsh.locale=zh`)**: it would keep the suite green while removing the only place the browser-derived path runs in an assembled app; pinning the browser language instead exercises the new resolution end to end.
+
+## Consequences
+
+- 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`: the package specs stub it (`zh-CN` as the baseline; the detection spec varies it), and any future spec asserting a default must pin one too.
+- Detection cost is one array walk per service construction, and no storage write, so boot behavior and the persisted-state surface are unchanged.

+# Agent Note: 全新浏览器打开的设置语言由浏览器决定
+
+Status: implemented
+
+[English](2026-07-31-browser-derived-initial-locale.md) | 中文
+
+## Problem
+
+设置里的语言行在每一次首访时都以中文开场：`LocaleService` 从 localStorage 读取 `dsh.locale`，读不到就直接回落到 `zh`。浏览器本已声明其使用者阅读哪些语言——`navigator.languages` 就是这份声明——而应用对此视而不见，于是英文读者迎面撞上一个中文产品，还得先找到一行中文标签的设置项才能脱身。回落值当时同时承担两份职责：既是无法解析出 locale 时的最后兜底，也是所有从未做过选择的用户拿到的答案。
+
+## Decision
+
+**初始 locale 依次经三个来源解析：已持久化的偏好、浏览器、`FALLBACK_LOCALE`。** `packages/client/locale/src/client/index.ts` 中的 `resolveInitialLocale()` 在服务构造时运行，是这一顺序的唯一表达处；`restorePreference()` 现在返回 `LocaleId | undefined`（存储项缺失、无法解析或不可访问，一律读作*没有偏好*），后一个来源才有开口的机会。
+
+**浏览器匹配按主子标签进行，且遍历有序列表。** `detectBrowserLocale()` 遍历 `[...navigator.languages, navigator.language]`，返回主子标签命中已提供 locale 的首个条目，因此 `zh-Hans-CN` 与 `zh-TW` 同归 `zh`、`en-GB` 归 `en`；而只请求本应用不提供的语言（`fr`、`de`）的浏览器则什么都匹配不到，交由 `FALLBACK_LOCALE` 接管。`navigator.language` 排在列表之后，因为有的浏览器只暴露前者；完全没有 `navigator` 的运行环境（node 启动客户端树）与任何无法解析的情形一样落到回落值。
+
+**显式选择是永久的。** `setLocale` 的持久化未作改动，且持久化值最先被查询，因此选过语言的用户即便在不同浏览器配置或系统语言之间辗转也保留原选择。没有任何代码把探测到的 locale 写回存储：探测在每次启动时重新推导，对"用户是否做过选择"这一问题始终不可见。
+
+**浏览器 e2e 车道现在钉住浏览器语言，而不只是存储项。** 断言中文文案的场景（`access-confirmation`、`models-settings`、`onboarding-deepseek-config`、`settings-chrome`）以 `apps/web/tests/support.ts` 的 `locale: ZH_BROWSER_LOCALE` 打开页面；`newEnglishPage` 仍然钉 `dsh.locale=en`，它依旧压过任何浏览器语言。`settings-chrome.e2e.ts` 新增一个场景：另开一个存储项为空的 `en-US` 页面，断言设置界面以英文呈现——这是本功能在组装后应用中的证据。
+
+## Alternatives considered
+
+- **`Intl.DateTimeFormat().resolvedOptions().locale` 或单读 `navigator.language`**：两者都把用户的有序偏好列表塌缩成一个标签，于是 `['de', 'en', 'zh']` 的读者拿到的是 zh 而非 en。列表恰恰是浏览器这份声明里最值得读的部分。
+- **首次启动即持久化探测结果**：那会把探测变成一次性事件，让一次陈旧的首访凌驾于此后改变的浏览器语言之上，也摧毁了整个解析顺序所依赖的区分——存储值将不再意味着"用户选了它"。
+- **完整的 BCP 47 协商（`Intl.LocaleMatcher` 式查找、地区与文字权重）**：在只提供两个语言互异的 locale 时，主子标签匹配就是正确答案的全部；协商层只会带来无行为支撑、也无从测试的表面积。
+- **为默认 locale 增加一个 cordis config key**：此处部署之间并无差异——回落值是产品对"完全没有信号"给出的答案，不是旋钮。仓库策略把 `Config` 字段留给有当前消费者、且随部署变化的选择。
+- **让 e2e 车道的中文场景继续钉存储项（`dsh.locale=zh`）**：那会让套件保持绿色，却抹掉浏览器推导路径在组装后应用中唯一的运行处；改钉浏览器语言才能端到端地演练新的解析过程。
+
+## Consequences
+
+- 来自英文浏览器的首访落在英文界面，而语言行依然呈现同样两个以自身语言自述的选项，两个方向的脱身通道都未改变。
+- `FALLBACK_LOCALE` 收窄回它真正的职责——字典回落与无信号时的答案——不再兼职充当"用户尚未选择"。
+- 在 jsdom 下构造 `LocaleService` 的测试现在依赖环境的 `navigator`：包内测试对其打桩（以 `zh-CN` 为基线，探测用例则逐个变换），今后任何断言默认值的用例同样必须钉住它。
+- 探测的代价是每次服务构造遍历一次数组，且不写存储，因此启动行为与持久化状态面均无变化。

 No single-shot transient-DOM assertions: every hop from replay yield to React commit can coalesce chunks, so sampling `[data-streaming]` is a race by construction. Streaming incrementality is asserted from the persisted `assistant/chunk` events (model-visible ⟺ logged makes the log the authoritative proof). `dsh-llm-replay`'s opt-in `paceMs` (default absent = burst) is a realism knob so the browser observes genuinely incremental SSE; correctness never leans on it, and abort during a pace wait cancels promptly.

Scaffold `close()` calls the `ReplayHandle.assertConsumed()` teardown check (every recorded script bound, every cursor drained), converting silent underruns and shifted bindings into crisp diagnostics. No vitest retry on the lane; one chromium per file, fresh context per scenario, one host per scenario; viewport pinned; interaction selectors anchor on roles, `data-*` attributes, and visible text, while the frame and conversation-region captures use the existing CSS-module local-name anchors. Standard scenarios set `dsh.locale=en` before client boot so localized role locators and goldens use one explicit language; `settings-chrome.e2e.ts` alone leaves storage unset to cover the default Chinese state and both switch directions.

Subject: [PATCH 090/101] fix(web-read-card): mark read-row summary chrome
 jscpd:ignore

The keyed toolviews (read, file-mutation, web) each draw the same ToolRow
summary-line chrome; the read row's copy trips the duplication gate against the
file-mutation row. Extracting the shared row is a separate change tracked for
all rows at once, so this scopes the exemption to the read row's block.

Subject: [PATCH 092/101] 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.

 goldens for keyed read row
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

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 094/101] 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 096/101] feat(cli): dsh --dump-config / --dump-default-config
 print the composed tree
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

dsh --dump-config and dsh web --dump-config compose the shipped base,
the surface overlay, and the --config or personal overlay — exactly the
layers that surface boots — and print the entry list as YAML without
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.

(cherry picked from commit 1fdbebfa8a5dc7df840d53666320064a7e3dae59)

+# 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。

+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 TUI surface:
 
@@ -17,6 +17,8 @@ The TUI surface:
 
 `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`.
+
 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`。

@@ -39,6 +39,7 @@ 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. **`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 097/101] 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
+
+English | [中文](2026-07-31-drop-user-message-edit-stub.zh.md)
+
+## 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.

+
+## 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。

+`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。

 - **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.

+# 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。
+
+## 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。

+# 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。

 **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`.

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.

Feature-owned rows (Permission, Language, Appearance), sections (Models), and conditional onboarding steps stay with their feature packages.

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 path above is the installer's default. If you set `DSH_SOURCE` or `DSH_CURRENT`, or reused an existing checkout, replace `~/.dsh/source/current` with that checkout path; see [`scripts/install.sh`](scripts/install.sh) for details.

See the [architecture](docs/architecture.md) for the underlying design.\n- **Runs are reconstructable.** Anything visible to the model is logged in the authoritative session stream; persistence, resume/fork/query, replay, telemetry, and UIs derive from the same events. See the [session-log architecture](docs/architecture.md#session-log).\n- **Code Mode (opt-in).** It exposes a `run_code` tool and a generated TypeScript SDK; only program output re-enters model context.
