 A new `packages/hooks/` group with `hook-protocol` as a pure library. It owns four primitive families and the `hook/*` session events; each bridge plugin (`dsh-hooks-claude`, `dsh-hooks-codex`) owns what genuinely differs.
 
 **Shared (here):**
-- **Matcher** — `matchesMatcher(pattern, query, mode)`. The ONE axis the dialects differ on is collapsed to the `mode` parameter: `claude` treats a pure `[A-Za-z0-9_|]+` pattern as a literal (pipe = exact-match alternation) and anything else as a regex; `codex` is always an unanchored regex. Match-all on absent/`''`/`'*'`; an invalid regex matches nothing (never throws into the loop).
+- **Matcher** — `matcherDiagnostic(pattern, mode)` and `matchesMatcher(pattern, query, mode)`. The ONE axis the dialects differ on is collapsed to the `mode` parameter: `claude` treats a pure `[A-Za-z0-9_|]+` pattern as a literal (pipe = exact-match alternation) and anything else as a regex; `codex` is always an unanchored regex. Match-all on absent/`''`/`'*'`. Each bridge validates runnable matcher groups while parsing and treats an invalid regex as a whole-config load failure, with a stable dialect/pattern/event diagnostic; no hook listeners are registered. Runtime matching still contains an invalid regex as a non-match, so a direct library caller never throws into the loop.
 - **Execution** — `runHook(bash, hook, options)`. Runs a command hook through the `ctx.bash` seam rather than a bespoke `spawn`: the executor already provides the scrubbed-but-overridable env, process-group kills, and timeout the protocol needs, and `dsh-bash`'s `stdin`/`env` fields (added for exactly this) are the trusted-plugin surface an in-process bridge is allowed to use. It serializes the bridge-built payload to stdin (trailing newline iff CC), honors the hook's `timeoutSec` (else `DEFAULT_HOOK_TIMEOUT_MS`, the 10-minute reference default both dialects share), and never throws (an executor rejection becomes a non-blocking-error `HookOutput`).
 - **Decode** — `parseHookOutput(exit, stdout, stderr)`, the exit-code + structured-stdout codec, producing a dialect-neutral `HookOutput`. Exit `0` → lenient JSON parse of stdout; exit `2` → blocking error with `stderr` as the reason (surfaced as `decision: 'block'` so no caller needs a separate exit-code branch); other → non-blocking error. Parses the CC structured-stdout fields that have a consumer on some path (`continue`/`stopReason`/`decision`/`hookSpecificOutput.{permissionDecision,additionalContext,updatedInput}`/`systemMessage`); the bridge honors only the subset meaningful for its dialect. Fields with no consumer on any path are not parsed at all (CC's `suppressOutput` — hook stdout never enters a transcript here, so there is nothing to suppress; see [the tighten-hook-protocol-contract Agent Note](../simplification/2026-07-04-tighten-hook-protocol-contract.md)).
 - **Merge** — `mergeHookOutputs(outputs)`, folding multiple matched hooks into one most-restrictive `MergedHookOutcome`: permission precedence **deny > ask > allow**, halt sticky on the first `continue:false`, block reasons joined `\n\n`, context/system-messages accumulated in order.

 - **执行** — `runHook(bash, hook, options)`。通过 `ctx.bash` seam 而非自建 `spawn` 运行命令钩子：执行器已提供清洗但可覆盖的 env、进程组 kill 和超时，正是协议所需的能力；`dsh-bash` 的 `stdin`/`env` 字段（正是为此添加的）是进程内桥接插件被允许使用的受信插件接口。它将桥接插件构建的 payload 序列化到 stdin（CC 时追加尾部换行），遵守钩子的 `timeoutSec`（否则使用 `DEFAULT_HOOK_TIMEOUT_MS`，即两种方言共享的 10 分钟参考默认值），且从不抛异常（执行器拒绝变为 non-blocking-error 的 `HookOutput`）。
 - **解码** — `parseHookOutput(exit, stdout, stderr)`，exit-code + structured-stdout 编解码器，产出方言无关的 `HookOutput`。Exit `0` → 宽松 JSON 解析 stdout；exit `2` → blocking error，`stderr` 为原因（以 `decision: 'block'` 呈现，调用方无需单独处理 exit-code 分支）；其他 → non-blocking error。解析 CC structured-stdout 中在某条路径上有消费方的字段（`continue`/`stopReason`/`decision`/`hookSpecificOutput.{permissionDecision,additionalContext,updatedInput}`/`systemMessage`）；桥接插件只采纳对其方言有意义的子集。在任何路径上都没有消费方的字段不予解析（CC 的 `suppressOutput`——钩子 stdout 在此处从不进入 transcript（文本记录），因此无需抑制；见 [收紧钩子协议契约 Agent Note](../simplification/2026-07-04-tighten-hook-protocol-contract.md)）。
 - **合并** — `mergeHookOutputs(outputs)`，将多个匹配钩子的输出折叠为一个最严格的 `MergedHookOutcome`：权限优先级 **deny > ask > allow**，halt 在首个 `continue:false` 时粘滞，阻止原因以 `\n\n` 拼接，context/system-messages 按序累积。

Bridge parsers use `matcherDiagnostic` to reject an invalid regex with a stable diagnostic before registering any hooks. The runtime predicate still contains an invalid pattern as a non-match, so a direct library caller cannot throw into the agent loop.
 - **`runHook(bash, hook, options, now)`** — require and forward the caller-owned `options.signal`, serialize `options.payload` to the hook's stdin (with a trailing newline iff `options.trailingNewline`), merge `options.env` after the executor's credential scrub (the `dsh-bash` trusted-plugin surface), honor the hook's `timeoutSec` (else `options.defaultTimeoutMs` — the bridge owns the default, its config defaulting to the lib's `DEFAULT_HOOK_TIMEOUT_MS` 10-minute reference), and decode the result (threading `options.expectedEventName` to the codec). Cancellation therefore reaches the executor's process-group kill and join boundary. Never throws: an executor rejection (infra fault) becomes a `HookOutput` with `exitCode: undefined` (a non-blocking error). `now` is injected for testable durations.
 - **`parseHookOutput(exitCode, stdout, stderr, expectedEventName?)`** decodes exit status and structured stdout. Exit 2 blocks with stderr; other failures are non-blocking. A matching hook-specific permission decision overrides the legacy top-level decision; mismatched or missing event discriminators suppress only event-specific fields. Top-level fields remain event-agnostic, and successful non-JSON output is left to the bridge.
 - **`mergeHookOutputs(outputs)`** — fold the results of every hook that matched one point: permission precedence **deny > ask > allow**, halt sticky on the first `continue:false`, block reasons joined with `\n\n`, `additionalContext`/`systemMessages` accumulated in order.

 ## Consequences
 
-Each bridge parses config atomically, builds its dialect payload, invokes the shared runner and merge logic, maps the decision, and appends `hook/*`. Protocol tests cover every matcher mode and diagnostic, exit-code and codec field, runner plumbing, merge precedence, and audit helper at per-file 100%; bridge tests exercise the library's real load path and pin invalid-config containment. `updatedInput` is parsed but only logged and warned until the [input-rewrite proposal](../../proposed/feature/2026-06-30-pre-tool-input-rewrite.md) lands.
+Each bridge parses config atomically, builds its dialect payload, invokes the shared runner and merge logic, maps the decision, and appends `hook/*`. Protocol tests cover every matcher mode and diagnostic, exit-code and codec field, runner plumbing, merge precedence, and audit helper at per-file 100%; bridge tests exercise the library's load path and pin the exact warning. Keyless ACP snapshots boot both bridges through the real Loader/app path with a valid blocking group before an invalid matcher, then prove the request reaches the replay model and persists no `hook/*` rows, so partial registration cannot hide behind a hand-mounted context. `updatedInput` is parsed but only logged and warned until the [input-rewrite proposal](../../proposed/feature/2026-06-30-pre-tool-input-rewrite.md) lands.

 A new `packages/hooks/` group with `hook-protocol` as a pure library. It owns four primitive families and the `hook/*` session events; each bridge plugin (`dsh-hooks-claude`, `dsh-hooks-codex`) owns what genuinely differs.
 
 **Shared (here):**
-- **Matcher** — `matcherDiagnostic(pattern, mode)` and `matchesMatcher(pattern, query, mode)`. The ONE axis the dialects differ on is collapsed to the `mode` parameter: `claude` treats a pure `[A-Za-z0-9_|]+` pattern as a literal (pipe = exact-match alternation) and anything else as a regex; `codex` is always an unanchored regex. Match-all on absent/`''`/`'*'`. Each bridge validates runnable matcher groups while parsing and treats an invalid regex as a whole-config load failure, with a stable dialect/pattern/event diagnostic; no hook listeners are registered. Runtime matching still contains an invalid regex as a non-match, so a direct library caller never throws into the loop.

Runs a command hook through the `ctx.bash` seam rather than a bespoke `spawn`: the executor already provides the scrubbed-but-overridable env, process-group kills, and timeout the protocol needs, and `dsh-bash`'s `stdin`/`env` fields (added for exactly this) are the trusted-plugin surface an in-process bridge is allowed to use. It serializes the bridge-built payload to stdin (trailing newline iff CC), honors the hook's `timeoutSec` (else `DEFAULT_HOOK_TIMEOUT_MS`, the 10-minute reference default both dialects share), and never throws (an executor rejection becomes a non-blocking-error `HookOutput`).
 - **Decode** — `parseHookOutput(exit, stdout, stderr)`, the exit-code + structured-stdout codec, producing a dialect-neutral `HookOutput`. Exit `0` → lenient JSON parse of stdout; exit `2` → blocking error with `stderr` as the reason (surfaced as `decision: 'block'` so no caller needs a separate exit-code branch); other → non-blocking error. Parses the CC structured-stdout fields that have a consumer on some path (`continue`/`stopReason`/`decision`/`hookSpecificOutput.{permissionDecision,additionalContext,updatedInput}`/`systemMessage`); the bridge honors only the subset meaningful for its dialect. Fields with no consumer on any path are not parsed at all (CC's `suppressOutput` — hook stdout never enters a transcript here, so there is nothing to suppress; see [the tighten-hook-protocol-contract Agent Note](../simplification/2026-07-04-tighten-hook-protocol-contract.md)).
 - **Merge** — `mergeHookOutputs(outputs)`, folding multiple matched hooks into one most-restrictive `MergedHookOutcome`: permission precedence **deny > ask > allow**, halt sticky on the first `continue:false`, block reasons joined `\n\n`, context/system-messages accumulated in order.

 在 `packages/hooks/` 分组下新建 `hook-protocol` 作为纯库。它拥有四个原语族和 `hook/*` 会话事件；每个桥接插件（`dsh-hooks-claude`、`dsh-hooks-codex`）拥有真正不同的部分。
 
 **共享（本库）：**
-- **Matcher** — `matcherDiagnostic(pattern, mode)` 与 `matchesMatcher(pattern, query, mode)`。两种方言唯一不同的轴被收敛为 `mode` 参数：`claude` 将纯 `[A-Za-z0-9_|]+` 模式视为字面量（管道符 = 精确匹配的多选），其余视为正则；`codex` 始终是无锚定正则。缺省/`''`/`'*'` 匹配一切。每个桥接插件在解析时校验可运行的 matcher group，将无效正则视为整份配置加载失败，输出稳定的方言/模式/事件诊断，且不注册任何钩子监听器。运行时匹配仍将无效正则收敛为不匹配，因此直接调用本库时绝不向 agent loop（智能体循环）抛异常。

 - **执行** — `runHook(bash, hook, options)`。通过 `ctx.bash` seam 而非自建 `spawn` 运行命令钩子：执行器已提供清洗但可覆盖的 env、进程组 kill 和超时，正是协议所需的能力；`dsh-bash` 的 `stdin`/`env` 字段（正是为此添加的）是进程内桥接插件被允许使用的受信插件接口。它将桥接插件构建的 payload 序列化到 stdin（CC 时追加尾部换行），遵守钩子的 `timeoutSec`（否则使用 `DEFAULT_HOOK_TIMEOUT_MS`，即两种方言共享的 10 分钟参考默认值），且从不抛异常（执行器拒绝变为 non-blocking-error 的 `HookOutput`）。
 - **解码** — `parseHookOutput(exit, stdout, stderr)`，exit-code + structured-stdout 编解码器，产出方言无关的 `HookOutput`。Exit `0` → 宽松 JSON 解析 stdout；exit `2` → blocking error，`stderr` 为原因（以 `decision: 'block'` 呈现，调用方无需单独处理 exit-code 分支）；其他 → non-blocking error。解析 CC structured-stdout 中在某条路径上有消费方的字段（`continue`/`stopReason`/`decision`/`hookSpecificOutput.{permissionDecision,additionalContext,updatedInput}`/`systemMessage`）；桥接插件只采纳对其方言有意义的子集。在任何路径上都没有消费方的字段不予解析（CC 的 `suppressOutput`——钩子 stdout 在此处从不进入 transcript（文本记录），因此无需抑制；见 [收紧钩子协议契约 Agent Note](../simplification/2026-07-04-tighten-hook-protocol-contract.md)）。
 - **合并** — `mergeHookOutputs(outputs)`，将多个匹配钩子的输出折叠为一个最严格的 `MergedHookOutcome`：权限优先级 **deny > ask > allow**，halt 在首个 `continue:false` 时粘滞，阻止原因以 `\n\n` 拼接，context/system-messages 按序累积。

The comparison baseline is Claude Code's [official hook-event reference](https://code.claude.com/docs/en/hooks#hook-events).
 - **`SessionStart` is partial:** JSON `additionalContext` is consumed, but plain stdout context, `initialUserMessage`, `sessionTitle`, `watchPaths`, `reloadSkills`, and `CLAUDE_ENV_FILE` are unsupported. The hook runs detached, so context can miss the first request (`TODO(session-start-gating)`), and the payload omits current optional fields such as `model`, `agent_type`, and `session_title`.
 - **`UserPromptSubmit` is partial:** blocking and JSON `additionalContext` work, but plain stdout context, `sessionTitle`, and `suppressOriginalPrompt` are unsupported. Unless overridden, the bridge also uses its 600-second default instead of Claude Code's event-specific 30-second command timeout.
 - **`PreToolUse` is partial:** `deny` and `ask` decisions work; `allow` does not pre-approve, `defer` is unsupported, `additionalContext` is ignored, and `updatedInput` is logged + warned but not honored ([the pre-tool-input-rewrite Agent Note](../../../.agents/notes/proposed/feature/2026-06-30-pre-tool-input-rewrite.md)).

 - **`UserPromptSubmit` 只支持部分功能：** 支持阻塞与 JSON `additionalContext`，但不支持纯 stdout 上下文、`sessionTitle` 和 `suppressOriginalPrompt`。除非被覆盖，否则桥接还会使用自身 600 秒默认值，而非 Claude Code 的事件特定 30 秒 command 超时。

 A resumed agent creates a new loop instance and injects a baseline composed from current files before its first request. This permits current baseline content on resume without mutating an earlier history event. A resume and a hot plugin remount both face a log that may already hold a baseline; they are told apart by `agent/session-start`, which a startup or resume emits before the first step while a remount attaches to an already-live session and never sees it. A remount retains the existing baseline only when its typed event remains in the current visible surface, and still rebuilds scope and provider-version tracking from current files. If compaction has shadowed that event, the remount injects a current baseline. A resume always re-composes.

 The plugin owns the complete `<system-reminder>` framing, and every injected `user/message` reaches the model verbatim with no core wrapper.

A scenario's committed `workspace/` is copied into that child first, then `prepareWorkspace` runs against the generated cwd before the agent starts. Reserve this hook for fixtures Git cannot represent portably, keep ordinary seeds in `workspace/`, and pair it with `posixOnly` when the generated paths are invalid on Windows. Each pinning directory stores the normalized full prompt sequence in generated `system-prompt.expected.md` and the corresponding full tool-schema sequence in generated `tool-schemas.expected.json`; `session.jsonl` stores `"system":"{{system}}","tools":"{{tools}}"` while retaining config, reason, and any model-visible prefix. A pin with legitimate mid-run header changes declares `expectedHeaderChanges`, which fixes the length of both sidecar sequences.
 
 Every scenario compares `stdout.expected.jsonl` with cwd-rooted separators canonicalized to `/`. On Windows, `pinsNativeWindowsStdout` additionally compares the complete `stdout.expected.windows.jsonl` after the shared expected output and requires that sidecar exactly when enabled. A scenario whose driven behavior needs POSIX process semantics (e.g. cancelling a live bash call kills a detached process group) declares `posixOnly`, which skips its run test on Windows while the fixture guards keep covering its committed files everywhere.

+# Agent Note: Experimental plugin package group
+
+Status: proposed
+
+English | [中文](2026-07-28-experimental-plugin-package-group.zh.md)
+
+## Problem
+
+The [package hierarchy](../../../../packages/README.md) groups plugins by product role, but it cannot distinguish supported plugins from prototypes whose contracts and continued existence remain unsettled. After the first tagged release, contributors still need an obvious place for useful experiments that carry no stability, compatibility, migration, or support warranty.
+
+## Proposal
+
+Add `packages/experimental/<pkg>/` as the required home for Cordis plugin packages whose whole public contract is experimental. Package names remain `@deepseek-ai/dsh-<pkg>`; promotion moves the package into its product-role group without renaming it.
+
+Experimental packages carry no stability, compatibility, migration, or support promise: they may change APIs, configuration, or data, or disappear, without deprecation or migration. This status does not relax engineering standards; these packages retain the repository's type, test, security, documentation, lifecycle, and snapshot requirements. Non-experimental packages must not take runtime dependencies on them. Examples may use them; any other runtime dependent is itself experimental and belongs under `packages/experimental/`. Tests may use them as development dependencies.
+
+Examples include the pending `@deepseek-ai/dsh-tui-session-changes` `/diff` viewer and the `/btw` plugin; if accepted, they land in this group. A release never promotes a package implicitly. Promotion requires explicit review of the public contract, limitations, test evidence, and a named owner accepting stable-package obligations.
+
+## Alternatives considered
+
+**Keep experiments in product-role groups with README labels.** Labels are easy to miss and cannot enforce dependency boundaries.
+
+**Treat every package as experimental until the first tagged release.** This provides no durable incubation boundary.
+
+**Develop experiments elsewhere.** This loses the real plugin graph, examples, snapshots, and lifecycle checks needed to evaluate them.
+
+## Acceptance criteria
+
+- `packages/experimental/` has a concise group README defining the package-level status, all four disclaimed promises, and the promotion rule.
+- Constraints require every experimental plugin package and every non-example runtime dependent of one to live there.
+- Package and user documentation label experimental plugins and avoid stability, compatibility, migration, or support promises.
+
+## Risks
+
+The group can become a junk drawer or let “experimental” excuse weak engineering. The repository's [current-owner/current-need rule](../../../../packages/AGENTS.md) and unchanged engineering gates limit that risk. Promotion causes path churn, but the npm name remains stable.

+# Agent Note: 实验性插件包（package）分组
+
+Status: proposed
+
+[English](2026-07-28-experimental-plugin-package-group.md) | 中文
+
+## 问题
+
+[包层级结构](../../../../packages/README.md)按产品角色对插件分组，但无法区分受支持的插件和契约与去留均未确定的原型。首个带标签的版本发布后，贡献者仍需要一个明确的位置存放有价值的实验性插件；这些插件不提供稳定性、兼容性、迁移或支持保证。
+
+## 提案
+
+新增 `packages/experimental/<pkg>/`，并要求公开契约整体处于实验阶段的 Cordis 插件包全部放在其中。包名仍为 `@deepseek-ai/dsh-<pkg>`；提升为稳定插件时，只将包移入对应的产品角色分组，不对其重命名。
+
+实验性包不提供稳定性、兼容性、迁移或支持保证：其 API、配置和数据可以变更，包也可以移除，均不提供弃用期或迁移路径。实验性状态不表示降低工程标准；这些包仍须满足仓库对类型、测试、安全、文档、生命周期和快照的要求。非实验性包不得将其列为运行时依赖。示例包可以使用它们；其他任何运行时依赖方本身也必须是实验性包，并位于 `packages/experimental/` 下。测试可以将其用作开发依赖。
+
+示例包括尚待完成的 `@deepseek-ai/dsh-tui-session-changes` `/diff` 查看器和 `/btw` 插件；如果获准合入，它们将直接进入该分组。发布不会自动将包提升为稳定状态。提升前必须明确评审其公开契约、限制和测试证据，并指定一名愿意承担稳定包义务的负责人。
+
+## 考虑过的替代方案
+
+**将实验性插件留在产品角色分组中，并用 README 标注。** 标注容易被忽略，也无法强制执行依赖边界。
+
+**首个版本发布前，将所有包都视为实验性。** 这无法提供持久的孵化边界。
+
+**在其他位置开发实验性插件。** 这会失去评估它们所需的真实插件图、示例、快照和生命周期检查。
+
+## 验收标准
+
+- `packages/experimental/` 包含一份简明的分组 README，定义包级状态、明确排除的四类保证以及提升规则。
+- 约束规则要求所有实验性插件包及其所有非示例运行时依赖方位于该目录。
+- 包文档和用户文档标明插件的实验性状态，且不作稳定性、兼容性、迁移或支持承诺。
+
+## 风险
+
+该分组可能无序积累原型，也可能让「实验性」成为降低工程标准的借口。仓库已有的[「必须有当前负责人和实际需求」规则](../../../../packages/AGENTS.md)以及不变的工程门禁可限制这项风险。提升为稳定插件会导致路径变动，但 npm 包名保持稳定。

 Add `packages/experimental/<pkg>/` as the required home for Cordis plugin packages whose whole public contract is experimental. Package names remain `@deepseek-ai/dsh-<pkg>`; promotion moves the package into its product-role group without renaming it.
 
+The group is also the team's in-repository place to share prototypes: members can discover, run, review, and extend one another's work against the real plugin graph without implying product support.

 Experimental packages carry no stability, compatibility, migration, or support promise: they may change APIs, configuration, or data, or disappear, without deprecation or migration. This status does not relax engineering standards; these packages retain the repository's type, test, security, documentation, lifecycle, and snapshot requirements. Non-experimental packages must not take runtime dependencies on them. Examples may use them; any other runtime dependent is itself experimental and belongs under `packages/experimental/`. Tests may use them as development dependencies.
 
 Examples include the pending `@deepseek-ai/dsh-tui-session-changes` `/diff` viewer and the `/btw` plugin; if accepted, they land in this group. A release never promotes a package implicitly. Promotion requires explicit review of the public contract, limitations, test evidence, and a named owner accepting stable-package obligations.

+# Agent Note: Experimental and internal package group
+
+Status: implemented
+
+English | [中文](2026-07-28-experimental-plugin-package-group.zh.md)
+
+## Problem
+
+The [package hierarchy](../../../../packages/README.md) groups plugins by product role, but it cannot distinguish release packages from prototypes or internal-only packages. The team needs an obvious shared place for useful work that is not part of the official release.
+
+## Decision
+
+The subtree rules in [`packages/experimental/AGENTS.md`](../../../../packages/experimental/AGENTS.md) make `packages/experimental/<pkg>/` the required home for Cordis plugin packages whose whole public contract is experimental or internal-only. Package names remain `@deepseek-ai/dsh-<pkg>`.
+
+The group is the team's in-repository place to share engineering and product-manager prototypes: members can discover, run, review, and extend one another's work against the real plugin graph without implying product support.
+
+Official releases exclude this directory. A package enters a release only after moving to its product-role group; release packages cannot take runtime dependencies on packages here. Examples may use them, while any other runtime dependent also belongs here. Tests may use them as development dependencies.
+
+Experimental packages carry no stability, compatibility, migration, or support promise: they may change APIs, configuration, or data, or disappear without deprecation or migration. Internal-only packages may define narrower internal contracts but make no public release promise. Neither status relaxes engineering, security, documentation, lifecycle, testing, or snapshot requirements.
+
+The pending `@deepseek-ai/dsh-tui-session-changes` `/diff` viewer and `/btw` plugin are examples governed by this rule. Promotion into an official release requires explicit review of the public contract, limitations, test evidence, and a named owner accepting stable-package obligations.
+
+## Alternatives considered
+
+**Keep experimental and internal-only packages in product-role groups with README labels.** Labels are easy to miss and cannot enforce dependency boundaries.
+
+**Treat every package as experimental until the first tagged release.** This provides no durable incubation boundary.
+
+**Develop prototypes and internal packages elsewhere.** This loses the real plugin graph, examples, snapshots, and lifecycle checks needed to evaluate them.
+
+## Consequences
+
+The path makes release exclusion and dependency blast radius visible while retaining the real plugin graph for team sharing. It gives up product-role colocation and creates path churn on promotion, while the npm name remains stable. The subtree rules, repository [current-owner/current-need rule](../../../../packages/AGENTS.md), and unchanged engineering gates limit junk-drawer growth. Because official release tooling does not yet exist, contributor policy enforces the exclusion; the directory is its required exclusion boundary when added.

+# Agent Note: 实验性与内部专用包（package）分组
+
+Status: implemented
+
+[English](2026-07-28-experimental-plugin-package-group.md) | 中文
+
+## 问题
+
+[包层级结构](../../../../packages/README.md)按产品角色对插件分组，但无法区分发布包、原型和内部专用包。团队需要一个明确的共享位置，存放不属于官方发布版本的有价值成果。
+
+## 决策
+
+[`packages/experimental/AGENTS.md`](../../../../packages/experimental/AGENTS.md) 中的子树规则要求所有公开契约整体处于实验状态或仅限内部使用的 Cordis 插件包位于 `packages/experimental/<pkg>/`。包名仍为 `@deepseek-ai/dsh-<pkg>`。
+
+该分组供团队在仓库内共享工程人员和产品经理制作的原型：成员可以基于真实插件图发现、运行、评审并扩展彼此的原型，但这不代表产品会提供支持。
+
+官方发布版本不包含此目录。包只有移入对应的产品角色分组后才会纳入发布版本；发布包不得在运行时依赖此处的包。示例可以使用这些包；其他任何运行时依赖方也必须位于此处。测试可以将它们用作开发依赖。
+
+实验性包不提供稳定性、兼容性、迁移或支持保证：其 API、配置或数据可以变更，包也可以移除，均不提供弃用期或迁移路径。内部专用包可以定义范围更窄的内部契约，但不作公开发布承诺。无论哪种状态，都不降低仓库对工程、安全、文档、生命周期、测试或快照的要求。
+
+尚待完成的 `@deepseek-ai/dsh-tui-session-changes` `/diff` 查看器和 `/btw` 插件都受这项规则约束。将包提升为稳定包并纳入官方发布版本，需要明确评审其公开契约、限制和测试证据，并指定一名愿意承担稳定包义务的负责人。
+
+## 考虑过的替代方案
+
+**将实验性和内部专用包留在产品角色分组中，并用 README 标注。** 标注容易被忽略，也无法强制执行依赖边界。
+
+**首个带标签的版本发布前，将所有包都视为实验性。** 这无法提供持久的孵化边界。
+
+**在其他位置开发原型和内部专用包。** 这会失去评估它们所需的真实插件图、示例、快照和生命周期检查。
+
+## 后果
+
+该路径明确标示不纳入发布版本的包及其依赖影响范围，同时保留供团队共享成果的真实插件图。代价是这些包无法与同产品角色的包共置，提升并纳入发布版本时还会产生路径变动，但 npm 包名保持稳定。子树规则、仓库已有的[「必须有当前负责人和实际需求」规则](../../../../packages/AGENTS.md)以及保持不变的工程门禁，可限制该分组无序膨胀。由于官方发布工具尚不存在，目前由贡献者政策执行这项排除规则；添加发布工具后，必须以该目录为排除边界。

-## Problem
-
-The [package hierarchy](../../../../packages/README.md) groups plugins by product role, but it cannot distinguish supported plugins from prototypes whose contracts and continued existence remain unsettled. After the first tagged release, contributors still need an obvious place for useful experiments that carry no stability, compatibility, migration, or support warranty.
-
-## Proposal
-
-Add `packages/experimental/<pkg>/` as the required home for Cordis plugin packages whose whole public contract is experimental. Package names remain `@deepseek-ai/dsh-<pkg>`; promotion moves the package into its product-role group without renaming it.
-
-The group is also the team's in-repository place to share prototypes: members can discover, run, review, and extend one another's work against the real plugin graph without implying product support.
-
-Experimental packages carry no stability, compatibility, migration, or support promise: they may change APIs, configuration, or data, or disappear, without deprecation or migration. This status does not relax engineering standards; these packages retain the repository's type, test, security, documentation, lifecycle, and snapshot requirements. Non-experimental packages must not take runtime dependencies on them. Examples may use them; any other runtime dependent is itself experimental and belongs under `packages/experimental/`. Tests may use them as development dependencies.
-
-Examples include the pending `@deepseek-ai/dsh-tui-session-changes` `/diff` viewer and the `/btw` plugin; if accepted, they land in this group. A release never promotes a package implicitly. Promotion requires explicit review of the public contract, limitations, test evidence, and a named owner accepting stable-package obligations.
-
-## Alternatives considered

-**Keep experiments in product-role groups with README labels.** Labels are easy to miss and cannot enforce dependency boundaries.
-
-**Treat every package as experimental until the first tagged release.** This provides no durable incubation boundary.
-
-**Develop experiments elsewhere.** This loses the real plugin graph, examples, snapshots, and lifecycle checks needed to evaluate them.
-
-## Acceptance criteria
-
-- `packages/experimental/` has a concise group README defining the package-level status, all four disclaimed promises, and the promotion rule.
-- Constraints require every experimental plugin package and every non-example runtime dependent of one to live there.
-- Package and user documentation label experimental plugins and avoid stability, compatibility, migration, or support promises.
-
-## Risks
-
-The group can become a junk drawer or let “experimental” excuse weak engineering. The repository's [current-owner/current-need rule](../../../../packages/AGENTS.md) and unchanged engineering gates limit that risk. Promotion causes path churn, but the npm name remains stable.

-## 问题
-
-[包层级结构](../../../../packages/README.md)按产品角色对插件分组，但无法区分受支持的插件和契约与去留均未确定的原型。首个带标签的版本发布后，贡献者仍需要一个明确的位置存放有价值的实验性插件；这些插件不提供稳定性、兼容性、迁移或支持保证。
-
-## 提案
-
-新增 `packages/experimental/<pkg>/`，并要求公开契约整体处于实验阶段的 Cordis 插件包全部放在其中。包名仍为 `@deepseek-ai/dsh-<pkg>`；提升为稳定插件时，只将包移入对应的产品角色分组，不对其重命名。
-
-该分组也是团队在仓库内共享原型的位置：成员可以基于真实插件图发现、运行、评审并扩展彼此的原型，但这不代表产品会提供支持。
-
-实验性包不提供稳定性、兼容性、迁移或支持保证：其 API、配置和数据可以变更，包也可以移除，均不提供弃用期或迁移路径。实验性状态不表示降低工程标准；这些包仍须满足仓库对类型、测试、安全、文档、生命周期和快照的要求。非实验性包不得将其列为运行时依赖。示例包可以使用它们；其他任何运行时依赖方本身也必须是实验性包，并位于 `packages/experimental/` 下。测试可以将其用作开发依赖。

-**首个版本发布前，将所有包都视为实验性。** 这无法提供持久的孵化边界。
-
-**在其他位置开发实验性插件。** 这会失去评估它们所需的真实插件图、示例、快照和生命周期检查。
-
-## 验收标准
-
-- `packages/experimental/` 包含一份简明的分组 README，定义包级状态、明确排除的四类保证以及提升规则。
-- 约束规则要求所有实验性插件包及其所有非示例运行时依赖方位于该目录。
-- 包文档和用户文档标明插件的实验性状态，且不作稳定性、兼容性、迁移或支持承诺。
-
-## 风险
-
-该分组可能无序积累原型，也可能让「实验性」成为降低工程标准的借口。仓库已有的[「必须有当前负责人和实际需求」规则](../../../../packages/AGENTS.md)以及不变的工程门禁可限制这项风险。提升为稳定插件会导致路径变动，但 npm 包名保持稳定。

+# AGENTS.md — Experimental and internal packages
+
+These rules supplement the [package rules](../AGENTS.md). The [experimental and internal package group decision](../../.agents/notes/implemented/architecture/2026-07-28-experimental-plugin-package-group.md) owns the rationale.
+
+- All Cordis plugin packages whose whole public contract is experimental or internal-only belong here. An experimental option inside an otherwise stable package stays in that package's product-role group.
+- Use this directory to share engineering and product-manager prototypes across the team so others can discover, run, review, and extend them against the real plugin graph.
+- Official releases exclude this directory. A package enters a release only after moving to its product-role group; do not add packages here to release manifests or bundles.
+- Experimental packages carry no stability, compatibility, migration, or support promise. Internal-only packages may define narrower internal contracts but make no public release promise.
+- Experimental or internal-only status never relaxes repository engineering, security, documentation, lifecycle, testing, or snapshot requirements.
+- Release packages must not take runtime dependencies on packages here. Examples may; every other runtime dependent is also experimental or internal-only and belongs here. Tests may use them as development dependencies.
+- Promotion moves a package to its product-role group without renaming its `@deepseek-ai/dsh-*` package. Require explicit review of its public contract, limitations, test evidence, and a named owner accepting stable-package obligations.

+A scenario booting a differently-composed tree sets its own `configPath` (an overlay whose basename still ends in `cordis.yml`, so the bin's replay swap finds the sibling `*cordis.snapshot.yml`) and, when that composition changes the request header, its own `headerClass` with its own pinning scenario — the acp-agent example's Code Mode and filesystem scenarios are templates. Default generated workspaces are stored in session fixtures as `{{cwd}}` so platform temp roots and random basenames do not affect recordings; `workspaceParent` moves the generated cwd outside the platform temp area when temporary-directory grants are themselves under test, keeps that explicit path in the fixture, and remains parent-owned while the harness removes only the generated child. A scenario's committed `workspace/` is copied into that child first, then `prepareWorkspace` runs against the generated cwd before the agent starts. Reserve this hook for fixtures Git cannot represent portably, keep ordinary seeds in `workspace/`, and pair it with `posixOnly` when the generated paths are invalid on Windows.
 
 A pin owns its generated `system-prompt.expected.md` or `tool-schemas.expected.json` by default; `systemPromptSource` and `toolSchemasSource` name another pin when the complete corresponding sequence is identical, so each distinct version is committed once. The pin's `session.jsonl` stores `"system":"{{system}}","tools":"{{tools}}"` while retaining config, reason, and any model-visible prefix. A pin with legitimate mid-run header changes declares `expectedHeaderChanges`; a shared source must declare the same count, and record/refresh rejects claimants that generate different bytes.

-- **Matcher** — `matcherDiagnostic(pattern, mode)` and `matchesMatcher(pattern, query, mode)`. The ONE axis the dialects differ on is collapsed to the `mode` parameter: `claude` treats a pure `[A-Za-z0-9_|]+` pattern as a literal (pipe = exact-match alternation) and anything else as a regex; `codex` is always an unanchored regex. Match-all on absent/`''`/`'*'`. Each bridge ignores unsupported events before group parsing, validates runnable groups for supported events, and treats an invalid regex there as a whole-config load failure, with a stable dialect/pattern/event diagnostic; no hook listeners are registered. Runtime matching still contains an invalid regex as a non-match, so a direct library caller never throws into the loop.

Runtime matching still contains an invalid regex as a non-match, so a direct library caller never throws into the loop.
 - **Execution** — `runHook(bash, hook, options)`. Runs a command hook through the `ctx.bash` seam rather than a bespoke `spawn`: the executor already provides the scrubbed-but-overridable env, process-group kills, and timeout the protocol needs, and `dsh-bash`'s `stdin`/`env` fields (added for exactly this) are the trusted-plugin surface an in-process bridge is allowed to use. It serializes the bridge-built payload to stdin (trailing newline iff CC), honors the hook's `timeoutSec` (else `DEFAULT_HOOK_TIMEOUT_MS`, the 10-minute reference default both dialects share), and never throws (an executor rejection becomes a non-blocking-error `HookOutput`).
 - **Decode** — `parseHookOutput(exit, stdout, stderr)`, the exit-code + structured-stdout codec, producing a dialect-neutral `HookOutput`. Exit `0` → lenient JSON parse of stdout; exit `2` → blocking error with `stderr` as the reason (surfaced as `decision: 'block'` so no caller needs a separate exit-code branch); other → non-blocking error. Parses the CC structured-stdout fields that have a consumer on some path (`continue`/`stopReason`/`decision`/`hookSpecificOutput.{permissionDecision,additionalContext,updatedInput}`/`systemMessage`); the bridge honors only the subset meaningful for its dialect. Fields with no consumer on any path are not parsed at all (CC's `suppressOutput` — hook stdout never enters a transcript here, so there is nothing to suppress; see [the tighten-hook-protocol-contract Agent Note](../simplification/2026-07-04-tighten-hook-protocol-contract.md)).
 - **Merge** — `mergeHookOutputs(outputs)`, folding multiple matched hooks into one most-restrictive `MergedHookOutcome`: permission precedence **deny > ask > allow**, halt sticky on the first `continue:false`, block reasons joined `\n\n`, context/system-messages accumulated in order.

 在 `packages/hooks/` 分组下新建 `hook-protocol` 作为纯库。它拥有四个原语族和 `hook/*` 会话事件；每个桥接插件（`dsh-hooks-claude`、`dsh-hooks-codex`）拥有真正不同的部分。
 
 **共享（本库）：**
-- **Matcher** — `matcherDiagnostic(pattern, mode)` 与 `matchesMatcher(pattern, query, mode)`。两种方言唯一不同的轴被收敛为 `mode` 参数：`claude` 将纯 `[A-Za-z0-9_|]+` 模式视为字面量（管道符 = 精确匹配的多选），其余视为正则；`codex` 始终是无锚定正则。缺省/`''`/`'*'` 匹配一切。每个桥接插件会在解析 group 前忽略不支持的事件，仅校验受支持事件中可运行的 group；其中的无效正则会导致整份配置加载失败，并输出稳定的方言／模式／事件诊断，且不注册任何 hook 监听器。运行时匹配仍将无效正则收敛为不匹配，因此直接调用本库时绝不向 agent loop（智能体循环）抛异常。

 - **执行** — `runHook(bash, hook, options)`。通过 `ctx.bash` seam 而非自建 `spawn` 运行命令钩子：执行器已提供清洗但可覆盖的 env、进程组 kill 和超时，正是协议所需的能力；`dsh-bash` 的 `stdin`/`env` 字段（正是为此添加的）是进程内桥接插件被允许使用的受信插件接口。它将桥接插件构建的 payload 序列化到 stdin（CC 时追加尾部换行），遵守钩子的 `timeoutSec`（否则使用 `DEFAULT_HOOK_TIMEOUT_MS`，即两种方言共享的 10 分钟参考默认值），且从不抛异常（执行器拒绝变为 non-blocking-error 的 `HookOutput`）。
 - **解码** — `parseHookOutput(exit, stdout, stderr)`，exit-code + structured-stdout 编解码器，产出方言无关的 `HookOutput`。Exit `0` → 宽松 JSON 解析 stdout；exit `2` → blocking error，`stderr` 为原因（以 `decision: 'block'` 呈现，调用方无需单独处理 exit-code 分支）；其他 → non-blocking error。解析 CC structured-stdout 中在某条路径上有消费方的字段（`continue`/`stopReason`/`decision`/`hookSpecificOutput.{permissionDecision,additionalContext,updatedInput}`/`systemMessage`）；桥接插件只采纳对其方言有意义的子集。在任何路径上都没有消费方的字段不予解析（CC 的 `suppressOutput`——钩子 stdout 在此处从不进入 transcript（文本记录），因此无需抑制；见 [收紧钩子协议契约 Agent Note](../simplification/2026-07-04-tighten-hook-protocol-contract.md)）。
 - **合并** — `mergeHookOutputs(outputs)`，将多个匹配钩子的输出折叠为一个最严格的 `MergedHookOutcome`：权限优先级 **deny > ask > allow**，halt 在首个 `continue:false` 时粘滞，阻止原因以 `\n\n` 拼接，context/system-messages 按序累积。

Bridge parsers use `matcherDiagnostic` to reject an invalid regex with a stable diagnostic before registering any hooks. The runtime predicate still contains an invalid pattern as a non-match, so a direct library caller cannot throw into the agent loop.

The runtime predicate still contains an invalid pattern as a non-match, so a direct library caller cannot throw into the agent loop.
 - **`runHook(bash, hook, options, now)`** — require and forward the caller-owned `options.signal`, serialize `options.payload` to the hook's stdin (with a trailing newline iff `options.trailingNewline`), merge `options.env` after the executor's credential scrub (the `dsh-bash` trusted-plugin surface), honor the hook's `timeoutSec` (else `options.defaultTimeoutMs` — the bridge owns the default, its config defaulting to the lib's `DEFAULT_HOOK_TIMEOUT_MS` 10-minute reference), and decode the result (threading `options.expectedEventName` to the codec). Cancellation therefore reaches the executor's process-group kill and join boundary. Never throws: an executor rejection (infra fault) becomes a `HookOutput` with `exitCode: undefined` (a non-blocking error). `now` is injected for testable durations.
 - **`parseHookOutput(exitCode, stdout, stderr, expectedEventName?)`** decodes exit status and structured stdout. Exit 2 blocks with stderr; other failures are non-blocking. A matching hook-specific permission decision overrides the legacy top-level decision; mismatched or missing event discriminators suppress only event-specific fields. Top-level fields remain event-agnostic, and successful non-JSON output is left to the bridge.
 - **`mergeHookOutputs(outputs)`** — fold the results of every hook that matched one point: permission precedence **deny > ask > allow**, halt sticky on the first `continue:false`, block reasons joined with `\n\n`, `additionalContext`/`systemMessages` accumulated in order.

 - **`runHook(bash, hook, options, now)`**：要求并转发调用方拥有的 `options.signal`，将 `options.payload` 序列化到 hook stdin（当且仅当 `options.trailingNewline` 时添加尾随换行符），在执行器凭证清理后合并 `options.env`（`dsh-bash` 受信任插件表层），遵循 hook 的 `timeoutSec`（否则使用 `options.defaultTimeoutMs`；默认值属于桥接，其配置默认为 lib 的 `DEFAULT_HOOK_TIMEOUT_MS` 10 分钟参考值），再解码结果（将 `options.expectedEventName` 传递给 codec）。因此取消会到达执行器的进程组终止与 join 边界。它绝不抛出异常：执行器拒绝（基础设施故障）会变为 `HookOutput`，其 `exitCode: undefined`（非阻塞错误）。`now` 会被注入，以便测试持续时间。
 - **`parseHookOutput(exitCode, stdout, stderr, expectedEventName?)`** 解码退出状态与结构化 stdout。退出码 2 使用 stderr 阻塞；其他失败不阻塞。匹配的 hook 特定权限决策会覆盖遗留顶层决策；事件判别字段不匹配或缺失只会抑制事件特定字段。顶层字段仍与事件无关，成功但非 JSON 的输出会留给桥接处理。
 - **`mergeHookOutputs(outputs)`**：折叠在一个点上匹配的每个 hook 结果：权限优先级为 **deny > ask > allow**，首个 `continue:false` 使 halt 粘滞，阻塞原因用 `\n\n` 连接，`additionalContext`／`systemMessages` 按顺序累积。

 A new `packages/hooks/` group with `hook-protocol` as a pure library. It owns four primitive families and the `hook/*` session events; each bridge plugin (`dsh-hooks-claude`, `dsh-hooks-codex`) owns what genuinely differs.
 
 **Shared (here):**
-- **Matcher** — `matcherDiagnostic(pattern, mode)` and `matchesMatcher(pattern, query, mode)`. The ONE axis the dialects differ on is collapsed to the `mode` parameter: `claude` treats a pure `[A-Za-z0-9_|]+` pattern as a literal (pipe = exact-match alternation) and anything else as a regex; `codex` is always an unanchored regex. Match-all on absent/`''`/`'*'`. Each bridge ignores unsupported events before group parsing, discards matcher fields on supported events without matcher subjects, validates the remaining runnable groups, and treats an invalid regex there as a whole-config load failure, with a stable dialect/pattern/event diagnostic; no hook listeners are registered. Runtime matching still contains an invalid regex as a non-match, so a direct library caller never throws into the loop.
+- **Matcher** — `matcherDiagnostic(pattern, mode)` and `matchesMatcher(pattern, query, mode)`. Pure `[A-Za-z0-9_|]+` patterns use the shared exact-match fast path (pipe = alternatives); the ONE remaining dialect axis is collapsed to `mode`: other Claude patterns use JavaScript `RegExp`, while other Codex patterns use Rust `regex`, including Rust-only syntax such as `(?i)`. Match-all on absent/`''`/`'*'`. Each bridge ignores unsupported events before group parsing, discards matcher fields on supported events without matcher subjects, validates the remaining runnable groups, and treats an invalid regex there as a whole-config load failure, with a stable dialect/pattern/event diagnostic; no hook listeners are registered. Runtime matching still contains an invalid regex as a non-match, so a direct library caller never throws into the loop.
 - **Execution** — `runHook(bash, hook, options)`. Runs a command hook through the `ctx.bash` seam rather than a bespoke `spawn`: the executor already provides the scrubbed-but-overridable env, process-group kills, and timeout the protocol needs, and `dsh-bash`'s `stdin`/`env` fields (added for exactly this) are the trusted-plugin surface an in-process bridge is allowed to use. It serializes the bridge-built payload to stdin (trailing newline iff CC), honors the hook's `timeoutSec` (else `DEFAULT_HOOK_TIMEOUT_MS`, the 10-minute reference default both dialects share), and never throws (an executor rejection becomes a non-blocking-error `HookOutput`).
 - **Decode** — `parseHookOutput(exit, stdout, stderr)`, the exit-code + structured-stdout codec, producing a dialect-neutral `HookOutput`. Exit `0` → lenient JSON parse of stdout; exit `2` → blocking error with `stderr` as the reason (surfaced as `decision: 'block'` so no caller needs a separate exit-code branch); other → non-blocking error. Parses the CC structured-stdout fields that have a consumer on some path (`continue`/`stopReason`/`decision`/`hookSpecificOutput.{permissionDecision,additionalContext,updatedInput}`/`systemMessage`); the bridge honors only the subset meaningful for its dialect. Fields with no consumer on any path are not parsed at all (CC's `suppressOutput` — hook stdout never enters a transcript here, so there is nothing to suppress; see [the tighten-hook-protocol-contract Agent Note](../simplification/2026-07-04-tighten-hook-protocol-contract.md)).
 - **Merge** — `mergeHookOutputs(outputs)`, folding multiple matched hooks into one most-restrictive `MergedHookOutcome`: permission precedence **deny > ask > allow**, halt sticky on the first `continue:false`, block reasons joined `\n\n`, context/system-messages accumulated in order.

 - **执行** — `runHook(bash, hook, options)`。通过 `ctx.bash` seam 而非自建 `spawn` 运行命令钩子：执行器已提供清洗但可覆盖的 env、进程组 kill 和超时，正是协议所需的能力；`dsh-bash` 的 `stdin`/`env` 字段（正是为此添加的）是进程内桥接插件被允许使用的受信插件接口。它将桥接插件构建的 payload 序列化到 stdin（CC 时追加尾部换行），遵守钩子的 `timeoutSec`（否则使用 `DEFAULT_HOOK_TIMEOUT_MS`，即两种方言共享的 10 分钟参考默认值），且从不抛异常（执行器拒绝变为 non-blocking-error 的 `HookOutput`）。
 - **解码** — `parseHookOutput(exit, stdout, stderr)`，exit-code + structured-stdout 编解码器，产出方言无关的 `HookOutput`。Exit `0` → 宽松 JSON 解析 stdout；exit `2` → blocking error，`stderr` 为原因（以 `decision: 'block'` 呈现，调用方无需单独处理 exit-code 分支）；其他 → non-blocking error。解析 CC structured-stdout 中在某条路径上有消费方的字段（`continue`/`stopReason`/`decision`/`hookSpecificOutput.{permissionDecision,additionalContext,updatedInput}`/`systemMessage`）；桥接插件只采纳对其方言有意义的子集。在任何路径上都没有消费方的字段不予解析（CC 的 `suppressOutput`——钩子 stdout 在此处从不进入 transcript（文本记录），因此无需抑制；见 [收紧钩子协议契约 Agent Note](../simplification/2026-07-04-tighten-hook-protocol-contract.md)）。
 - **合并** — `mergeHookOutputs(outputs)`，将多个匹配钩子的输出折叠为一个最严格的 `MergedHookOutcome`：权限优先级 **deny > ask > allow**，halt 在首个 `continue:false` 时粘滞，阻止原因以 `\n\n` 拼接，context/system-messages 按序累积。

 ## Primitives
 
-- **`matcherDiagnostic(matcher, mode)` / `matchesMatcher(matcher, query, mode)`** — match-all on absent/`''`/`'*'`; `claude` mode treats a pure `[A-Za-z0-9_|]+` pattern as a literal (pipe = exact-match alternation) and anything else as a regex; `codex` mode is always an unanchored regex. Bridge parsers discard matcher fields for events without matcher subjects, then use `matcherDiagnostic` to reject an invalid consumed regex with a stable diagnostic before registering any hooks. The runtime predicate still contains an invalid pattern as a non-match, so a direct library caller cannot throw into the agent loop.
+- **`matcherDiagnostic(matcher, mode)` / `matchesMatcher(matcher, query, mode)`** — match-all on absent/`''`/`'*'`; both dialects treat a pure `[A-Za-z0-9_|]+` pattern as exact pipe-separated alternatives. Other patterns are unanchored regexes compiled in the native dialect: JavaScript for Claude Code, Rust `regex` for Codex (including inline flags such as `(?i)`). Bridge parsers discard matcher fields for events without matcher subjects, then use `matcherDiagnostic` to reject an invalid consumed regex with a stable diagnostic before registering any hooks. The runtime predicate still contains an invalid pattern as a non-match, so a direct library caller cannot throw into the agent loop.
 - **`runHook(bash, hook, options, now)`** — require and forward the caller-owned `options.signal`, serialize `options.payload` to the hook's stdin (with a trailing newline iff `options.trailingNewline`), merge `options.env` after the executor's credential scrub (the `dsh-bash` trusted-plugin surface), honor the hook's `timeoutSec` (else `options.defaultTimeoutMs` — the bridge owns the default, its config defaulting to the lib's `DEFAULT_HOOK_TIMEOUT_MS` 10-minute reference), and decode the result (threading `options.expectedEventName` to the codec). Cancellation therefore reaches the executor's process-group kill and join boundary. Never throws: an executor rejection (infra fault) becomes a `HookOutput` with `exitCode: undefined` (a non-blocking error). `now` is injected for testable durations.
 - **`parseHookOutput(exitCode, stdout, stderr, expectedEventName?)`** decodes exit status and structured stdout. Exit 2 blocks with stderr; other failures are non-blocking. A matching hook-specific permission decision overrides the legacy top-level decision; mismatched or missing event discriminators suppress only event-specific fields. Top-level fields remain event-agnostic, and successful non-JSON output is left to the bridge.
 - **`mergeHookOutputs(outputs)`** — fold the results of every hook that matched one point: permission precedence **deny > ask > allow**, halt sticky on the first `continue:false`, block reasons joined with `\n\n`, `additionalContext`/`systemMessages` accumulated in order.

+- **`matcherDiagnostic(matcher, mode)` / `matchesMatcher(matcher, query, mode)`**：缺失、`''` 或 `'*'` 时匹配全部；两种方言都将纯 `[A-Za-z0-9_|]+` pattern 视为按 pipe 分隔的精确多选。其他 pattern 会用原生方言编译为未锚定正则：Claude Code 使用 JavaScript，Codex 使用 Rust `regex`（包括 `(?i)` 等内联 flag）。桥接解析器会丢弃没有 matcher 匹配对象的事件所带 matcher 字段，再使用 `matcherDiagnostic` 在注册任何 hook 之前拒绝实际会被消费的无效正则，并输出稳定诊断。运行时谓词仍将无效 pattern 收敛为不匹配，因此直接库调用无法向 agent loop 抛出异常。
 - **`runHook(bash, hook, options, now)`**：要求并转发调用方拥有的 `options.signal`，将 `options.payload` 序列化到 hook stdin（当且仅当 `options.trailingNewline` 时添加尾随换行符），在执行器凭证清理后合并 `options.env`（`dsh-bash` 受信任插件表层），遵循 hook 的 `timeoutSec`（否则使用 `options.defaultTimeoutMs`；默认值属于桥接，其配置默认为 lib 的 `DEFAULT_HOOK_TIMEOUT_MS` 10 分钟参考值），再解码结果（将 `options.expectedEventName` 传递给 codec）。因此取消会到达执行器的进程组终止与 join 边界。它绝不抛出异常：执行器拒绝（基础设施故障）会变为 `HookOutput`，其 `exitCode: undefined`（非阻塞错误）。`now` 会被注入，以便测试持续时间。
 - **`parseHookOutput(exitCode, stdout, stderr, expectedEventName?)`** 解码退出状态与结构化 stdout。退出码 2 使用 stderr 阻塞；其他失败不阻塞。匹配的 hook 特定权限决策会覆盖遗留顶层决策；事件判别字段不匹配或缺失只会抑制事件特定字段。顶层字段仍与事件无关，成功但非 JSON 的输出会留给桥接处理。
 - **`mergeHookOutputs(outputs)`**：折叠在一个点上匹配的每个 hook 结果：权限优先级为 **deny > ask > allow**，首个 `continue:false` 使 halt 粘滞，阻塞原因用 `\n\n` 连接，`additionalContext`／`systemMessages` 按顺序累积。

 A new `packages/hooks/` group with `hook-protocol` as a pure library. It owns four primitive families and the `hook/*` session events; each bridge plugin (`dsh-hooks-claude`, `dsh-hooks-codex`) owns what genuinely differs.
 
 **Shared (here):**
-- **Matcher** — `matcherDiagnostic(pattern, mode)` and `matchesMatcher(pattern, query, mode)`. Pure `[A-Za-z0-9_|]+` patterns use the shared exact-match fast path (pipe = alternatives); the ONE remaining dialect axis is collapsed to `mode`: other Claude patterns use JavaScript `RegExp`, while other Codex patterns use Rust `regex`, including Rust-only syntax such as `(?i)`. Match-all on absent/`''`/`'*'`. Each bridge ignores unsupported events before group parsing, discards matcher fields on supported events without matcher subjects, validates the remaining runnable groups, and treats an invalid regex there as a whole-config load failure, with a stable dialect/pattern/event diagnostic; no hook listeners are registered. Runtime matching still contains an invalid regex as a non-match, so a direct library caller never throws into the loop.

Each bridge ignores unsupported events before group parsing, discards matcher fields on supported events without matcher subjects, validates the remaining runnable groups, and treats an invalid regex there as a whole-config load failure, with a stable dialect/pattern/event diagnostic; no hook listeners are registered. For runtime, a bridge compiles its finite set of unique config patterns ONCE, reuses that set across hook points, and disposes it after detached runs drain on plugin teardown. This config-scoped ownership avoids a module-global cache while preventing repeated Rust/WASM construction from raising a non-shrinking memory high-water mark on every match. The one-shot predicate still contains an invalid regex as a non-match, so a direct library caller never throws into the loop.
 - **Execution** — `runHook(bash, hook, options)`. Runs a command hook through the `ctx.bash` seam rather than a bespoke `spawn`: the executor already provides the scrubbed-but-overridable env, process-group kills, and timeout the protocol needs, and `dsh-bash`'s `stdin`/`env` fields (added for exactly this) are the trusted-plugin surface an in-process bridge is allowed to use. It serializes the bridge-built payload to stdin (trailing newline iff CC), honors the hook's `timeoutSec` (else `DEFAULT_HOOK_TIMEOUT_MS`, the 10-minute reference default both dialects share), and never throws (an executor rejection becomes a non-blocking-error `HookOutput`).
 - **Decode** — `parseHookOutput(exit, stdout, stderr)`, the exit-code + structured-stdout codec, producing a dialect-neutral `HookOutput`. Exit `0` → lenient JSON parse of stdout; exit `2` → blocking error with `stderr` as the reason (surfaced as `decision: 'block'` so no caller needs a separate exit-code branch); other → non-blocking error. Parses the CC structured-stdout fields that have a consumer on some path (`continue`/`stopReason`/`decision`/`hookSpecificOutput.{permissionDecision,additionalContext,updatedInput}`/`systemMessage`); the bridge honors only the subset meaningful for its dialect. Fields with no consumer on any path are not parsed at all (CC's `suppressOutput` — hook stdout never enters a transcript here, so there is nothing to suppress; see [the tighten-hook-protocol-contract Agent Note](../simplification/2026-07-04-tighten-hook-protocol-contract.md)).
 - **Merge** — `mergeHookOutputs(outputs)`, folding multiple matched hooks into one most-restrictive `MergedHookOutcome`: permission precedence **deny > ask > allow**, halt sticky on the first `continue:false`, block reasons joined `\n\n`, context/system-messages accumulated in order.

 在 `packages/hooks/` 分组下新建 `hook-protocol` 作为纯库。它拥有四个原语族和 `hook/*` 会话事件；每个桥接插件（`dsh-hooks-claude`、`dsh-hooks-codex`）拥有真正不同的部分。
 
 **共享（本库）：**
-- **Matcher** — `matcherDiagnostic(pattern, mode)` 与 `matchesMatcher(pattern, query, mode)`。纯 `[A-Za-z0-9_|]+` pattern 使用共享的精确匹配快速路径（管道符 = 多选）；剩余的唯一方言差异收敛为 `mode`：其他 Claude pattern 使用 JavaScript `RegExp`，其他 Codex pattern 使用 Rust `regex`，包括 `(?i)` 等 Rust 专属语法。缺省/`''`/`'*'` 匹配一切。每个桥接插件会在解析 group 前忽略不支持的事件，丢弃受支持但没有 matcher 匹配对象的事件所带 matcher 字段，再校验剩余的可运行 group；其中的无效正则会导致整份配置加载失败，并输出稳定的方言／模式／事件诊断，且不注册任何 hook 监听器。运行时匹配仍将无效正则收敛为不匹配，因此直接调用本库时绝不向 agent loop（智能体循环）抛异常。
+- **Matcher** — `matcherDiagnostic(pattern, mode)`、`compileMatchers(patterns, mode)` 与 `matchesMatcher(pattern, query, mode)`。纯 `[A-Za-z0-9_|]+` pattern 使用共享的精确匹配快速路径（管道符 = 多选）；剩余的唯一方言差异收敛为 `mode`：其他 Claude pattern 使用 JavaScript `RegExp`，其他 Codex pattern 使用 Rust `regex`，包括 `(?i)` 等 Rust 专属语法。缺省/`''`/`'*'` 匹配一切。每个桥接插件会在解析 group 前忽略不支持的事件，丢弃受支持但没有 matcher 匹配对象的事件所带 matcher 字段，再校验剩余的可运行 group；其中的无效正则会导致整份配置加载失败，并输出稳定的方言／模式／事件诊断，且不注册任何 hook 监听器。运行时，桥接会将配置中有限的唯一 pattern 集合只编译一次，在各 hook 点重复使用，并在插件 teardown 时先 drain 脱离运行，再释放该集合。这种配置作用域的所有权既避免模块全局缓存，也防止反复构造 Rust／WASM 正则在每次匹配时抬高且无法收缩的内存高水位。一次性谓词仍将无效正则收敛为不匹配，因此直接调用本库时绝不向 agent loop（智能体循环）抛异常。
 - **执行** — `runHook(bash, hook, options)`。通过 `ctx.bash` seam 而非自建 `spawn` 运行命令钩子：执行器已提供清洗但可覆盖的 env、进程组 kill 和超时，正是协议所需的能力；`dsh-bash` 的 `stdin`/`env` 字段（正是为此添加的）是进程内桥接插件被允许使用的受信插件接口。它将桥接插件构建的 payload 序列化到 stdin（CC 时追加尾部换行），遵守钩子的 `timeoutSec`（否则使用 `DEFAULT_HOOK_TIMEOUT_MS`，即两种方言共享的 10 分钟参考默认值），且从不抛异常（执行器拒绝变为 non-blocking-error 的 `HookOutput`）。
 - **解码** — `parseHookOutput(exit, stdout, stderr)`，exit-code + structured-stdout 编解码器，产出方言无关的 `HookOutput`。Exit `0` → 宽松 JSON 解析 stdout；exit `2` → blocking error，`stderr` 为原因（以 `decision: 'block'` 呈现，调用方无需单独处理 exit-code 分支）；其他 → non-blocking error。解析 CC structured-stdout 中在某条路径上有消费方的字段（`continue`/`stopReason`/`decision`/`hookSpecificOutput.{permissionDecision,additionalContext,updatedInput}`/`systemMessage`）；桥接插件只采纳对其方言有意义的子集。在任何路径上都没有消费方的字段不予解析（CC 的 `suppressOutput`——钩子 stdout 在此处从不进入 transcript（文本记录），因此无需抑制；见 [收紧钩子协议契约 Agent Note](../simplification/2026-07-04-tighten-hook-protocol-contract.md)）。
 - **合并** — `mergeHookOutputs(outputs)`，将多个匹配钩子的输出折叠为一个最严格的 `MergedHookOutcome`：权限优先级 **deny > ask > allow**，halt 在首个 `continue:false` 时粘滞，阻止原因以 `\n\n` 拼接，context/system-messages 按序累积。

 ## Primitives
 
-- **`matcherDiagnostic(matcher, mode)` / `matchesMatcher(matcher, query, mode)`** — match-all on absent/`''`/`'*'`; both dialects treat a pure `[A-Za-z0-9_|]+` pattern as exact pipe-separated alternatives. Other patterns are unanchored regexes compiled in the native dialect: JavaScript for Claude Code, Rust `regex` for Codex (including inline flags such as `(?i)`). Bridge parsers discard matcher fields for events without matcher subjects, then use `matcherDiagnostic` to reject an invalid consumed regex with a stable diagnostic before registering any hooks. The runtime predicate still contains an invalid pattern as a non-match, so a direct library caller cannot throw into the agent loop.
+- **`matcherDiagnostic(matcher, mode)` / `compileMatchers(matchers, mode)` / `matchesMatcher(matcher, query, mode)`** — match-all on absent/`''`/`'*'`; both dialects treat a pure `[A-Za-z0-9_|]+` pattern as exact pipe-separated alternatives. Other patterns are unanchored regexes compiled in the native dialect: JavaScript for Claude Code, Rust `regex` for Codex (including inline flags such as `(?i)`). Bridge parsers discard matcher fields for events without matcher subjects, then use `matcherDiagnostic` to reject an invalid consumed regex with a stable diagnostic before registering any hooks. Each bridge uses `compileMatchers` to compile every unique config pattern once, reuses it at every hook point, and disposes the finite set after detached runs drain on plugin teardown; this avoids the Rust/WASM allocator's non-shrinking high-water mark growing on every match. `matchesMatcher` remains the contained one-shot predicate, and invalid runtime patterns are non-matches rather than exceptions.
 - **`runHook(bash, hook, options, now)`** — require and forward the caller-owned `options.signal`, serialize `options.payload` to the hook's stdin (with a trailing newline iff `options.trailingNewline`), merge `options.env` after the executor's credential scrub (the `dsh-bash` trusted-plugin surface), honor the hook's `timeoutSec` (else `options.defaultTimeoutMs` — the bridge owns the default, its config defaulting to the lib's `DEFAULT_HOOK_TIMEOUT_MS` 10-minute reference), and decode the result (threading `options.expectedEventName` to the codec). Cancellation therefore reaches the executor's process-group kill and join boundary. Never throws: an executor rejection (infra fault) becomes a `HookOutput` with `exitCode: undefined` (a non-blocking error). `now` is injected for testable durations.
 - **`parseHookOutput(exitCode, stdout, stderr, expectedEventName?)`** decodes exit status and structured stdout. Exit 2 blocks with stderr; other failures are non-blocking. A matching hook-specific permission decision overrides the legacy top-level decision; mismatched or missing event discriminators suppress only event-specific fields. Top-level fields remain event-agnostic, and successful non-JSON output is left to the bridge.
 - **`mergeHookOutputs(outputs)`** — fold the results of every hook that matched one point: permission precedence **deny > ask > allow**, halt sticky on the first `continue:false`, block reasons joined with `\n\n`, `additionalContext`/`systemMessages` accumulated in order.

 - **`runHook(bash, hook, options, now)`**：要求并转发调用方拥有的 `options.signal`，将 `options.payload` 序列化到 hook stdin（当且仅当 `options.trailingNewline` 时添加尾随换行符），在执行器凭证清理后合并 `options.env`（`dsh-bash` 受信任插件表层），遵循 hook 的 `timeoutSec`（否则使用 `options.defaultTimeoutMs`；默认值属于桥接，其配置默认为 lib 的 `DEFAULT_HOOK_TIMEOUT_MS` 10 分钟参考值），再解码结果（将 `options.expectedEventName` 传递给 codec）。因此取消会到达执行器的进程组终止与 join 边界。它绝不抛出异常：执行器拒绝（基础设施故障）会变为 `HookOutput`，其 `exitCode: undefined`（非阻塞错误）。`now` 会被注入，以便测试持续时间。
 - **`parseHookOutput(exitCode, stdout, stderr, expectedEventName?)`** 解码退出状态与结构化 stdout。退出码 2 使用 stderr 阻塞；其他失败不阻塞。匹配的 hook 特定权限决策会覆盖遗留顶层决策；事件判别字段不匹配或缺失只会抑制事件特定字段。顶层字段仍与事件无关，成功但非 JSON 的输出会留给桥接处理。
 - **`mergeHookOutputs(outputs)`**：折叠在一个点上匹配的每个 hook 结果：权限优先级为 **deny > ask > allow**，首个 `continue:false` 使 halt 粘滞，阻塞原因用 `\n\n` 连接，`additionalContext`／`systemMessages` 按顺序累积。

 A new `packages/hooks/` group with `hook-protocol` as a pure library. It owns four primitive families and the `hook/*` session events; each bridge plugin (`dsh-hooks-claude`, `dsh-hooks-codex`) owns what genuinely differs.
 
 **Shared (here):**
-- **Matcher** — `matcherDiagnostic(pattern, mode)`, `compileMatchers(patterns, mode)`, and `matchesMatcher(pattern, query, mode)`. Pure `[A-Za-z0-9_|]+` patterns use the shared exact-match fast path (pipe = alternatives); the ONE remaining dialect axis is collapsed to `mode`: other Claude patterns use JavaScript `RegExp`, while other Codex patterns use Rust `regex`, including Rust-only syntax such as `(?i)`. Match-all on absent/`''`/`'*'`. Each bridge ignores unsupported events before group parsing, discards matcher fields on supported events without matcher subjects, validates the remaining runnable groups, and treats an invalid regex there as a whole-config load failure, with a stable dialect/pattern/event diagnostic; no hook listeners are registered. For runtime, a bridge compiles its finite set of unique config patterns ONCE, reuses that set across hook points, and disposes it after detached runs drain on plugin teardown. This config-scoped ownership avoids a module-global cache while preventing repeated Rust/WASM construction from raising a non-shrinking memory high-water mark on every match. The one-shot predicate still contains an invalid regex as a non-match, so a direct library caller never throws into the loop.
+- **Matcher** — `compileMatchers(patterns, mode)`, `matcherDiagnostic(pattern, mode)`, and `matchesMatcher(pattern, query, mode)`.

Match-all on absent/`''`/`'*'`. Each bridge ignores unsupported events before group parsing, discards matcher fields on supported events without matcher subjects, collects the remaining runnable groups, and compiles their finite set of unique patterns ONCE. It reads validation diagnostics from that compiled registry: an invalid regex causes whole-config rejection after the registry is disposed, while a valid parse returns the SAME registry for hook-point matching and plugin-teardown disposal after detached runs drain. The stable diagnostic still names dialect/pattern/event and no hook listeners are registered on failure. This config-scoped ownership avoids both a module-global cache and separate validation/runtime Rust/WASM construction, whose non-shrinking allocator raises its memory high-water mark on every construction. The one-shot helpers remain contained, so a direct library caller never throws into the loop.
 - **Execution** — `runHook(bash, hook, options)`. Runs a command hook through the `ctx.bash` seam rather than a bespoke `spawn`: the executor already provides the scrubbed-but-overridable env, process-group kills, and timeout the protocol needs, and `dsh-bash`'s `stdin`/`env` fields (added for exactly this) are the trusted-plugin surface an in-process bridge is allowed to use. It serializes the bridge-built payload to stdin (trailing newline iff CC), honors the hook's `timeoutSec` (else `DEFAULT_HOOK_TIMEOUT_MS`, the 10-minute reference default both dialects share), and never throws (an executor rejection becomes a non-blocking-error `HookOutput`).
 - **Decode** — `parseHookOutput(exit, stdout, stderr)`, the exit-code + structured-stdout codec, producing a dialect-neutral `HookOutput`. Exit `0` → lenient JSON parse of stdout; exit `2` → blocking error with `stderr` as the reason (surfaced as `decision: 'block'` so no caller needs a separate exit-code branch); other → non-blocking error. Parses the CC structured-stdout fields that have a consumer on some path (`continue`/`stopReason`/`decision`/`hookSpecificOutput.{permissionDecision,additionalContext,updatedInput}`/`systemMessage`); the bridge honors only the subset meaningful for its dialect. Fields with no consumer on any path are not parsed at all (CC's `suppressOutput` — hook stdout never enters a transcript here, so there is nothing to suppress; see [the tighten-hook-protocol-contract Agent Note](../simplification/2026-07-04-tighten-hook-protocol-contract.md)).
 - **Merge** — `mergeHookOutputs(outputs)`, folding multiple matched hooks into one most-restrictive `MergedHookOutcome`: permission precedence **deny > ask > allow**, halt sticky on the first `continue:false`, block reasons joined `\n\n`, context/system-messages accumulated in order.

 在 `packages/hooks/` 分组下新建 `hook-protocol` 作为纯库。它拥有四个原语族和 `hook/*` 会话事件；每个桥接插件（`dsh-hooks-claude`、`dsh-hooks-codex`）拥有真正不同的部分。
 
 **共享（本库）：**
-- **Matcher** — `matcherDiagnostic(pattern, mode)`、`compileMatchers(patterns, mode)` 与 `matchesMatcher(pattern, query, mode)`。纯 `[A-Za-z0-9_|]+` pattern 使用共享的精确匹配快速路径（管道符 = 多选）；剩余的唯一方言差异收敛为 `mode`：其他 Claude pattern 使用 JavaScript `RegExp`，其他 Codex pattern 使用 Rust `regex`，包括 `(?i)` 等 Rust 专属语法。缺省/`''`/`'*'` 匹配一切。每个桥接插件会在解析 group 前忽略不支持的事件，丢弃受支持但没有 matcher 匹配对象的事件所带 matcher 字段，再校验剩余的可运行 group；其中的无效正则会导致整份配置加载失败，并输出稳定的方言／模式／事件诊断，且不注册任何 hook 监听器。运行时，桥接会将配置中有限的唯一 pattern 集合只编译一次，在各 hook 点重复使用，并在插件 teardown 时先 drain 脱离运行，再释放该集合。这种配置作用域的所有权既避免模块全局缓存，也防止反复构造 Rust／WASM 正则在每次匹配时抬高且无法收缩的内存高水位。一次性谓词仍将无效正则收敛为不匹配，因此直接调用本库时绝不向 agent loop（智能体循环）抛异常。

 - **执行** — `runHook(bash, hook, options)`。通过 `ctx.bash` seam 而非自建 `spawn` 运行命令钩子：执行器已提供清洗但可覆盖的 env、进程组 kill 和超时，正是协议所需的能力；`dsh-bash` 的 `stdin`/`env` 字段（正是为此添加的）是进程内桥接插件被允许使用的受信插件接口。它将桥接插件构建的 payload 序列化到 stdin（CC 时追加尾部换行），遵守钩子的 `timeoutSec`（否则使用 `DEFAULT_HOOK_TIMEOUT_MS`，即两种方言共享的 10 分钟参考默认值），且从不抛异常（执行器拒绝变为 non-blocking-error 的 `HookOutput`）。
 - **解码** — `parseHookOutput(exit, stdout, stderr)`，exit-code + structured-stdout 编解码器，产出方言无关的 `HookOutput`。Exit `0` → 宽松 JSON 解析 stdout；exit `2` → blocking error，`stderr` 为原因（以 `decision: 'block'` 呈现，调用方无需单独处理 exit-code 分支）；其他 → non-blocking error。解析 CC structured-stdout 中在某条路径上有消费方的字段（`continue`/`stopReason`/`decision`/`hookSpecificOutput.{permissionDecision,additionalContext,updatedInput}`/`systemMessage`）；桥接插件只采纳对其方言有意义的子集。在任何路径上都没有消费方的字段不予解析（CC 的 `suppressOutput`——钩子 stdout 在此处从不进入 transcript（文本记录），因此无需抑制；见 [收紧钩子协议契约 Agent Note](../simplification/2026-07-04-tighten-hook-protocol-contract.md)）。
 - **合并** — `mergeHookOutputs(outputs)`，将多个匹配钩子的输出折叠为一个最严格的 `MergedHookOutcome`：权限优先级 **deny > ask > allow**，halt 在首个 `continue:false` 时粘滞，阻止原因以 `\n\n` 拼接，context/system-messages 按序累积。

 ## Primitives
 
-- **`matcherDiagnostic(matcher, mode)` / `compileMatchers(matchers, mode)` / `matchesMatcher(matcher, query, mode)`** — match-all on absent/`''`/`'*'`; both dialects treat a pure `[A-Za-z0-9_|]+` pattern as exact pipe-separated alternatives. Other patterns are unanchored regexes compiled in the native dialect: JavaScript for Claude Code, Rust `regex` for Codex (including inline flags such as `(?i)`). Bridge parsers discard matcher fields for events without matcher subjects, then use `matcherDiagnostic` to reject an invalid consumed regex with a stable diagnostic before registering any hooks. Each bridge uses `compileMatchers` to compile every unique config pattern once, reuses it at every hook point, and disposes the finite set after detached runs drain on plugin teardown; this avoids the Rust/WASM allocator's non-shrinking high-water mark growing on every match. `matchesMatcher` remains the contained one-shot predicate, and invalid runtime patterns are non-matches rather than exceptions.
+- **`compileMatchers(matchers, mode)` / `matcherDiagnostic(matcher, mode)` / `matchesMatcher(matcher, query, mode)`** — match-all on absent/`''`/`'*'`; both dialects treat a pure `[A-Za-z0-9_|]+` pattern as exact pipe-separated alternatives. Other patterns are unanchored regexes compiled in the native dialect: JavaScript for Claude Code, Rust `regex` for Codex (including inline flags such as `(?i)`). A bridge parser first discards matcher fields for events without matcher subjects and collects the remaining runnable groups, then compiles their unique patterns once. It reads `registry.diagnostic(pattern)` from those exact instances, disposes the registry before throwing on an invalid consumed regex, or returns the same registry for runtime matching. The plugin reuses it at every hook point and disposes it after detached runs drain on teardown. Thus neither validation nor matching reconstructs a Rust/WASM regex and raises its non-shrinking memory high-water mark. `matcherDiagnostic` and `matchesMatcher` remain contained one-shot helpers; invalid runtime patterns are non-matches rather than exceptions.
 - **`runHook(bash, hook, options, now)`** — require and forward the caller-owned `options.signal`, serialize `options.payload` to the hook's stdin (with a trailing newline iff `options.trailingNewline`), merge `options.env` after the executor's credential scrub (the `dsh-bash` trusted-plugin surface), honor the hook's `timeoutSec` (else `options.defaultTimeoutMs` — the bridge owns the default, its config defaulting to the lib's `DEFAULT_HOOK_TIMEOUT_MS` 10-minute reference), and decode the result (threading `options.expectedEventName` to the codec). Cancellation therefore reaches the executor's process-group kill and join boundary. Never throws: an executor rejection (infra fault) becomes a `HookOutput` with `exitCode: undefined` (a non-blocking error). `now` is injected for testable durations.
 - **`parseHookOutput(exitCode, stdout, stderr, expectedEventName?)`** decodes exit status and structured stdout. Exit 2 blocks with stderr; other failures are non-blocking. A matching hook-specific permission decision overrides the legacy top-level decision; mismatched or missing event discriminators suppress only event-specific fields. Top-level fields remain event-agnostic, and successful non-JSON output is left to the bridge.
 - **`mergeHookOutputs(outputs)`** — fold the results of every hook that matched one point: permission precedence **deny > ask > allow**, halt sticky on the first `continue:false`, block reasons joined with `\n\n`, `additionalContext`/`systemMessages` accumulated in order.

 - **`runHook(bash, hook, options, now)`**：要求并转发调用方拥有的 `options.signal`，将 `options.payload` 序列化到 hook stdin（当且仅当 `options.trailingNewline` 时添加尾随换行符），在执行器凭证清理后合并 `options.env`（`dsh-bash` 受信任插件表层），遵循 hook 的 `timeoutSec`（否则使用 `options.defaultTimeoutMs`；默认值属于桥接，其配置默认为 lib 的 `DEFAULT_HOOK_TIMEOUT_MS` 10 分钟参考值），再解码结果（将 `options.expectedEventName` 传递给 codec）。因此取消会到达执行器的进程组终止与 join 边界。它绝不抛出异常：执行器拒绝（基础设施故障）会变为 `HookOutput`，其 `exitCode: undefined`（非阻塞错误）。`now` 会被注入，以便测试持续时间。
 - **`parseHookOutput(exitCode, stdout, stderr, expectedEventName?)`** 解码退出状态与结构化 stdout。退出码 2 使用 stderr 阻塞；其他失败不阻塞。匹配的 hook 特定权限决策会覆盖遗留顶层决策；事件判别字段不匹配或缺失只会抑制事件特定字段。顶层字段仍与事件无关，成功但非 JSON 的输出会留给桥接处理。
 - **`mergeHookOutputs(outputs)`**：折叠在一个点上匹配的每个 hook 结果：权限优先级为 **deny > ask > allow**，首个 `continue:false` 使 halt 粘滞，阻塞原因用 `\n\n` 连接，`additionalContext`／`systemMessages` 按顺序累积。

 A new `packages/hooks/` group with `hook-protocol` as a pure library. It owns four primitive families and the `hook/*` session events; each bridge plugin (`dsh-hooks-claude`, `dsh-hooks-codex`) owns what genuinely differs.
 
 **Shared (here):**
-- **Matcher** — `compileMatchers(patterns, mode)`, `matcherDiagnostic(pattern, mode)`, and `matchesMatcher(pattern, query, mode)`. Pure `[A-Za-z0-9_|]+` patterns use the shared exact-match fast path (pipe = alternatives); the ONE remaining dialect axis is collapsed to `mode`: other Claude patterns use JavaScript `RegExp`, while other Codex patterns use Rust `regex`, including Rust-only syntax such as `(?i)`. Match-all on absent/`''`/`'*'`. Each bridge ignores unsupported events before group parsing, discards matcher fields on supported events without matcher subjects, collects the remaining runnable groups, and compiles their finite set of unique patterns ONCE. It reads validation diagnostics from that compiled registry: an invalid regex causes whole-config rejection after the registry is disposed, while a valid parse returns the SAME registry for hook-point matching and plugin-teardown disposal after detached runs drain. The stable diagnostic still names dialect/pattern/event and no hook listeners are registered on failure. This config-scoped ownership avoids both a module-global cache and separate validation/runtime Rust/WASM construction, whose non-shrinking allocator raises its memory high-water mark on every construction. The one-shot helpers remain contained, so a direct library caller never throws into the loop.
+- **Matcher** — `compileMatchers(patterns, mode)`, `matcherDiagnostic(pattern, mode)`, and `matchesMatcher(pattern, query, mode)`.

Match-all on absent/`''`/`'*'`. Each bridge ignores unsupported events before group parsing, discards matcher fields on supported events without matcher subjects, collects the remaining runnable groups, and compiles their finite set of unique patterns ONCE. It reads validation diagnostics from that config registry: rejection disposes the registry before whole-config failure, while admission returns the SAME registry for hook-point matching and plugin-teardown disposal after detached runs drain. Codex valid instances and invalid diagnostics additionally use a versioned interner on the synchronous `rregex` CJS module, so one-shot calls and hook-protocol/Cordis reloads reuse them without putting state on `globalThis`. Because that dependency's WASM allocator does not shrink after `free()`, the interner deliberately retains at most `MAX_INTERNED_CODEX_REGEX_PATTERNS` (128) distinct non-literal patterns per process. At capacity, a new distinct pattern is rejected before native construction with a stable capacity/pattern/event diagnostic; known patterns remain usable and process restart resets the budget. The hard bound covers adversarial unique-pattern reloads without an unbounded cache, while direct library calls remain contained and never throw into the loop.
 - **Execution** — `runHook(bash, hook, options)`. Runs a command hook through the `ctx.bash` seam rather than a bespoke `spawn`: the executor already provides the scrubbed-but-overridable env, process-group kills, and timeout the protocol needs, and `dsh-bash`'s `stdin`/`env` fields (added for exactly this) are the trusted-plugin surface an in-process bridge is allowed to use. It serializes the bridge-built payload to stdin (trailing newline iff CC), honors the hook's `timeoutSec` (else `DEFAULT_HOOK_TIMEOUT_MS`, the 10-minute reference default both dialects share), and never throws (an executor rejection becomes a non-blocking-error `HookOutput`).
 - **Decode** — `parseHookOutput(exit, stdout, stderr)`, the exit-code + structured-stdout codec, producing a dialect-neutral `HookOutput`. Exit `0` → lenient JSON parse of stdout; exit `2` → blocking error with `stderr` as the reason (surfaced as `decision: 'block'` so no caller needs a separate exit-code branch); other → non-blocking error. Parses the CC structured-stdout fields that have a consumer on some path (`continue`/`stopReason`/`decision`/`hookSpecificOutput.{permissionDecision,additionalContext,updatedInput}`/`systemMessage`); the bridge honors only the subset meaningful for its dialect. Fields with no consumer on any path are not parsed at all (CC's `suppressOutput` — hook stdout never enters a transcript here, so there is nothing to suppress; see [the tighten-hook-protocol-contract Agent Note](../simplification/2026-07-04-tighten-hook-protocol-contract.md)).
 - **Merge** — `mergeHookOutputs(outputs)`, folding multiple matched hooks into one most-restrictive `MergedHookOutcome`: permission precedence **deny > ask > allow**, halt sticky on the first `continue:false`, block reasons joined `\n\n`, context/system-messages accumulated in order.

 在 `packages/hooks/` 分组下新建 `hook-protocol` 作为纯库。它拥有四个原语族和 `hook/*` 会话事件；每个桥接插件（`dsh-hooks-claude`、`dsh-hooks-codex`）拥有真正不同的部分。
 
 **共享（本库）：**
-- **Matcher** — `compileMatchers(patterns, mode)`、`matcherDiagnostic(pattern, mode)` 与 `matchesMatcher(pattern, query, mode)`。纯 `[A-Za-z0-9_|]+` pattern 使用共享的精确匹配快速路径（管道符 = 多选）；剩余的唯一方言差异收敛为 `mode`：其他 Claude pattern 使用 JavaScript `RegExp`，其他 Codex pattern 使用 Rust `regex`，包括 `(?i)` 等 Rust 专属语法。缺省/`''`/`'*'` 匹配一切。每个桥接插件会在解析 group 前忽略不支持的事件，丢弃受支持但没有 matcher 匹配对象的事件所带字段，收集其余可运行 group，再将其中有限的唯一 pattern 集合只编译一次。它直接从该 registry 读取校验诊断：无效正则会在释放 registry 后导致整份配置加载失败；有效解析则把同一个 registry 交给各 hook 点匹配，并在插件 teardown 时先 drain 脱离运行，再释放它。稳定诊断仍包含方言／模式／事件，失败时不会注册任何 hook 监听器。这种配置作用域的所有权既避免模块全局缓存，也避免校验和运行时分别构造 Rust／WASM 正则；其无法收缩的分配器会在每次构造时抬高内存高水位。一次性 helper 仍是收敛的，因此直接调用本库时绝不向 agent loop（智能体循环）抛异常。

 - **执行** — `runHook(bash, hook, options)`。通过 `ctx.bash` seam 而非自建 `spawn` 运行命令钩子：执行器已提供清洗但可覆盖的 env、进程组 kill 和超时，正是协议所需的能力；`dsh-bash` 的 `stdin`/`env` 字段（正是为此添加的）是进程内桥接插件被允许使用的受信插件接口。它将桥接插件构建的 payload 序列化到 stdin（CC 时追加尾部换行），遵守钩子的 `timeoutSec`（否则使用 `DEFAULT_HOOK_TIMEOUT_MS`，即两种方言共享的 10 分钟参考默认值），且从不抛异常（执行器拒绝变为 non-blocking-error 的 `HookOutput`）。
 - **解码** — `parseHookOutput(exit, stdout, stderr)`，exit-code + structured-stdout 编解码器，产出方言无关的 `HookOutput`。Exit `0` → 宽松 JSON 解析 stdout；exit `2` → blocking error，`stderr` 为原因（以 `decision: 'block'` 呈现，调用方无需单独处理 exit-code 分支）；其他 → non-blocking error。解析 CC structured-stdout 中在某条路径上有消费方的字段（`continue`/`stopReason`/`decision`/`hookSpecificOutput.{permissionDecision,additionalContext,updatedInput}`/`systemMessage`）；桥接插件只采纳对其方言有意义的子集。在任何路径上都没有消费方的字段不予解析（CC 的 `suppressOutput`——钩子 stdout 在此处从不进入 transcript（文本记录），因此无需抑制；见 [收紧钩子协议契约 Agent Note](../simplification/2026-07-04-tighten-hook-protocol-contract.md)）。
 - **合并** — `mergeHookOutputs(outputs)`，将多个匹配钩子的输出折叠为一个最严格的 `MergedHookOutcome`：权限优先级 **deny > ask > allow**，halt 在首个 `continue:false` 时粘滞，阻止原因以 `\n\n` 拼接，context/system-messages 按序累积。

-- **`compileMatchers(matchers, mode)` / `matcherDiagnostic(matcher, mode)` / `matchesMatcher(matcher, query, mode)`** — match-all on absent/`''`/`'*'`; both dialects treat a pure `[A-Za-z0-9_|]+` pattern as exact pipe-separated alternatives. Other patterns are unanchored regexes compiled in the native dialect: JavaScript for Claude Code, Rust `regex` for Codex (including inline flags such as `(?i)`). A bridge parser first discards matcher fields for events without matcher subjects and collects the remaining runnable groups, then compiles their unique patterns once. It reads `registry.diagnostic(pattern)` from those exact instances, disposes the registry before throwing on an invalid consumed regex, or returns the same registry for runtime matching. The plugin reuses it at every hook point and disposes it after detached runs drain on teardown. Thus neither validation nor matching reconstructs a Rust/WASM regex and raises its non-shrinking memory high-water mark. `matcherDiagnostic` and `matchesMatcher` remain contained one-shot helpers; invalid runtime patterns are non-matches rather than exceptions.
+- **`compileMatchers(matchers, mode)` / `matcherDiagnostic(matcher, mode)` / `matchesMatcher(matcher, query, mode)`** — match-all on absent/`''`/`'*'`; both dialects treat a pure `[A-Za-z0-9_|]+` pattern as exact pipe-separated alternatives. Other patterns are unanchored regexes compiled in the native dialect: JavaScript for Claude Code, Rust `regex` for Codex (including inline flags such as `(?i)`). A bridge parser first discards matcher fields for events without matcher subjects and collects the remaining runnable groups, then compiles their unique patterns once. It reads `registry.diagnostic(pattern)` from those exact instances, disposes the config registry before throwing on a rejected pattern, or returns that registry for runtime matching and teardown after detached runs drain. Codex's valid instances and invalid diagnostics are interned on the synchronous `rregex` dependency module, so they survive hook-protocol/Cordis reloads without using `globalThis`; one-shot helpers share the same interner. Because `rregex` cannot shrink its WASM allocation after `free()`, the process deliberately retains at most `MAX_INTERNED_CODEX_REGEX_PATTERNS` (128) distinct non-literal patterns. Once full, a new distinct pattern is rejected with a capacity diagnostic before calling WASM; previously interned patterns continue to work, and a process restart resets the budget. This is bounded for both same-pattern and adversarial unique reloads without an unbounded cache.
 - **`runHook(bash, hook, options, now)`** — require and forward the caller-owned `options.signal`, serialize `options.payload` to the hook's stdin (with a trailing newline iff `options.trailingNewline`), merge `options.env` after the executor's credential scrub (the `dsh-bash` trusted-plugin surface), honor the hook's `timeoutSec` (else `options.defaultTimeoutMs` — the bridge owns the default, its config defaulting to the lib's `DEFAULT_HOOK_TIMEOUT_MS` 10-minute reference), and decode the result (threading `options.expectedEventName` to the codec). Cancellation therefore reaches the executor's process-group kill and join boundary. Never throws: an executor rejection (infra fault) becomes a `HookOutput` with `exitCode: undefined` (a non-blocking error). `now` is injected for testable durations.
 - **`parseHookOutput(exitCode, stdout, stderr, expectedEventName?)`** decodes exit status and structured stdout. Exit 2 blocks with stderr; other failures are non-blocking. A matching hook-specific permission decision overrides the legacy top-level decision; mismatched or missing event discriminators suppress only event-specific fields. Top-level fields remain event-agnostic, and successful non-JSON output is left to the bridge.
 - **`mergeHookOutputs(outputs)`** — fold the results of every hook that matched one point: permission precedence **deny > ask > allow**, halt sticky on the first `continue:false`, block reasons joined with `\n\n`, `additionalContext`/`systemMessages` accumulated in order.

 - **`runHook(bash, hook, options, now)`**：要求并转发调用方拥有的 `options.signal`，将 `options.payload` 序列化到 hook stdin（当且仅当 `options.trailingNewline` 时添加尾随换行符），在执行器凭证清理后合并 `options.env`（`dsh-bash` 受信任插件表层），遵循 hook 的 `timeoutSec`（否则使用 `options.defaultTimeoutMs`；默认值属于桥接，其配置默认为 lib 的 `DEFAULT_HOOK_TIMEOUT_MS` 10 分钟参考值），再解码结果（将 `options.expectedEventName` 传递给 codec）。因此取消会到达执行器的进程组终止与 join 边界。它绝不抛出异常：执行器拒绝（基础设施故障）会变为 `HookOutput`，其 `exitCode: undefined`（非阻塞错误）。`now` 会被注入，以便测试持续时间。
 - **`parseHookOutput(exitCode, stdout, stderr, expectedEventName?)`** 解码退出状态与结构化 stdout。退出码 2 使用 stderr 阻塞；其他失败不阻塞。匹配的 hook 特定权限决策会覆盖遗留顶层决策；事件判别字段不匹配或缺失只会抑制事件特定字段。顶层字段仍与事件无关，成功但非 JSON 的输出会留给桥接处理。
 - **`mergeHookOutputs(outputs)`**：折叠在一个点上匹配的每个 hook 结果：权限优先级为 **deny > ask > allow**，首个 `continue:false` 使 halt 粘滞，阻塞原因用 `\n\n` 连接，`additionalContext`／`systemMessages` 按顺序累积。

+The config is parsed **once** at load. `configPath` is **process-level** — a relative path resolves against the process launch cwd at load time, not per-session (`TODO(per-session-hook-config)`). A read/parse failure is contained (logs + registers nothing); an invalid regex matcher on an event that consumes matchers is one such failure and reports its pattern and event. Non-literal Rust-regex patterns are interned across reloads under a process budget of 128 distinct patterns: once full, a new distinct pattern is rejected before WASM construction with a capacity diagnostic, while already interned patterns remain usable; restarting the process resets the budget. Only sync `type: 'command'` hooks run — a non-command or `async: true` hook is parsed-and-skipped with a warning. A hook accepts `timeout` or the `timeoutSec` alias; one that sets neither runs under the protocol's reference default (`DEFAULT_HOOK_TIMEOUT_MS` from `dsh-hook-protocol`, 10 minutes). Events outside the five bridge-supported points are dropped at parse.
 
 The hooks themselves run in the agent's session workspace: for the agent-scoped points the bridge passes the session's `cwd` as the hook process's working directory, so a hook operates in the user's project tree, not the server launch dir.

@@ -18,7 +18,7 @@ Placement and policy rulings folded into this decision:
 
 - **Not the `ctx.fs` seam.** `packages/fs/` is the model/session-facing storage stack (policy events, sandbox-swappable backends). Riding it would couple GUI browsing to the model's confinement backend — swapping `fs-sandbox` for the model must never change GUI behavior — and OS facts (home anchoring, hidden conventions) are not storage primitives. The picker seam stays presentation-free and model-free; `packages/host/` is its consumer-domain home.
 - **Dependency survey (hand-roll vs adopt).** Node's stdlib *is* the maintained cross-platform OS layer (`readdir(withFileTypes)`, `homedir`, path semantics); surveyed alternatives fail the dependency bar — file-manager packages (`node-file-manager`, `files-and-folders`, Syncfusion's provider) are whole HTTP apps (fit), drive-letter helpers (`drivelist` native addon, `windows-drive-letters` ~7y stale) fail health/proportionality. The browse backend is a thin adapter over stdlib.
-- **Hidden entries: return-and-flag.** The host stamps `hidden` (POSIX dot convention) and returns everything; the client filters. Display policy stays client-side, and the planned show-hidden toggle becomes a client-only change. Windows' `FILE_ATTRIBUTE_HIDDEN` is not exposed by dirents — documented limitation until a native probe pays for itself.
+- **Hidden entries: return-and-flag.** The host stamps `hidden` (POSIX dot convention) and returns everything; the client filters. Display policy stays client-side, and the show-hidden toggle shipped as exactly that client-only change (the browse client's footer toggle). Windows' `FILE_ATTRIBUTE_HIDDEN` is not exposed by dirents — documented limitation until a native probe pays for itself.
 - **Symlinks: follow for enterability.** `stat` probes symlinks (broken/cyclic → skipped); crumbs keep the logical path the operator navigated, and `workspace.create` already canonicalizes via realpath at adoption.
 - **Listing levels are bounded, and streamed.** One `list` call returns at most `maxEntries` rows (config, default 1000 — GitHub's web-UI directory-listing bound). The level streams via `opendir` into a name-sorted window of `maxEntries + 1` candidates, so memory stays O(maxEntries) and enterability probing touches only windowed candidates; the wire `DirectoryListing` carries a required `truncated` flag so the client states incompleteness instead of silently missing tail entries. A windowed broken symlink is not backfilled from beyond the window — the eviction already marks the level truncated. Window insertion is binary with an O(1) full-window tail rejection (an oversized level must not pay a window scan per dirent), and `list(path, signal)` threads the carrier's request signal so a scan of a stalled network directory cannot outlive a disconnected caller — every await in the scan (open, each read, each symlink probe) races the signal, an aborted exit abandons rather than awaits the close (Node queues close behind in-flight reads), and abandoned settlements are swallowed so cleanup can never surface as an unhandled rejection. An unbounded level is a memory/responsiveness hole for large or adversarial directories.
 - **Whole-filesystem scope, no roots config.** `workspace.create` accepts arbitrary paths and the API serves bash-driving methods, so a browse root would be UX scoping, not a boundary; configurability without a consumer fails the evidence bar. Deferred until a deployment needs it.

 Behavior facts: listings return **directories only**, name-sorted, with symlinks-to-directories followed (broken/cyclic links skipped — the probe `stat` failing means "not enterable") and a host-owned `hidden` flag (POSIX dot convention) left for the client to act on; `crumbs` is the root-to-target ancestor chain, the root crumb labeled by its full path (`/`, `C:\`); an absent `list` path means the host account's home directory. `createDirectory` is non-recursive (a missing parent is a real failure, not a level to invent) and validates the name as a single non-blank segment even when called directly, mirroring the wire schema's fence. Both primitives reject an explicit path that is not fully qualified — relative forms, and on Windows the rooted drive-less forms (`\foo`, `/foo`) and incomplete UNC prefixes (`\\`, `\\server`) that `isAbsolute` accepts — with `directory-unreadable`/`directory-create-failed`, instead of letting `resolve` rebase it under the host process cwd or current drive. One `list` call returns at most `maxEntries` rows (config, default 1000 — the bound GitHub's web UI applies to directory listings), and the level streams through a bounded window so memory stays O(maxEntries) no matter how many children the directory holds: a cut level keeps the name-sorted head, counts hidden rows against the bound, probes only windowed candidates, and reports `truncated: true` so the client can say the level is incomplete (a windowed broken symlink is not backfilled from beyond the window — the eviction already marks the level truncated); window insertion is binary with an O(1) full-window tail rejection, and `list` threads the caller's `AbortSignal` so a disconnect or timeout stops the scan instead of letting it outlive the caller. Failures throw the seam's typed `DirectoryPickerError`.

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

The pending question now owns exactly two surfaces: the redesigned
QuestionComposer takeover (footer pager, checkbox multi-select,
always-visible custom input, locale-injected bilingual chrome) collects
the answers, and a dedicated ask_user_question toolview row reports the
interaction outcome — waiting, N/M answered, cancelled (ASK_CANCELLED),
or interrupted with stopped semantics (ASK_ABORTED). PendingCard narrows
to approval waits only. Toolview leading icons and the hover chevron
unify on the tertiary label color, the checklist glyph matches the
14px figma extract, and dev-watch registers CSS modules so css-only
edits rebuild.

+## Problem
+
+The Web GUI could already collect answers through the `QuestionComposer` composer takeover, but the transcript around it was wrong on three counts. A pending question rendered twice: once as the composer takeover and once as the read-only `PendingCard` placeholder that predates the takeover. A settled `ask_user_question` call rendered as the generic "Tool call" row dumping raw args JSON, so the two composer verdicts — the user dismissing the whole set (`ASK_CANCELLED`) and a turn interrupt landing while the question was pending (`ASK_ABORTED`) — both read as anonymous red-dot failures. And the composer's own chrome copy (pager, buttons, placeholders, validation feedback) was hardcoded Chinese while the surrounding client is bilingual through `dsh-client-locale`.
+
+Separately, the composer visuals had drifted from the current design: an expand-to-open custom answer entry, no multi-select affordance beyond a trailing check, header-mounted paging, and a `（可多选）` title-suffix convention parsed out of model text.
+
+## Decision
+
+A pending question owns exactly two surfaces: the composer takeover collects the answers, and a dedicated `ask_user_question` toolview row in the transcript names the interaction outcome. The row registers into the keyed `conversation.chat.toolview` hole exactly like `todo_write` and composes the shared `ToolRow` (chrome, running sweep, leading expansion). Its summary is the interaction verdict rather than args: `waiting` while running, `N/M answered` from the result JSON once settled (a skipped answer — empty `selected`, no `custom` — stays out of the count), `cancelled` for `ASK_CANCELLED`, and `interrupted` with the shared amber stopped semantics for `ASK_ABORTED`. Malformed or truncated results fall back to the generic summary. `PendingCard` narrows to `PendingWait<'approval'>` and `ChatView` filters the pending list to approval waits, so the placeholder card now exists only for the approval takeover still on the roadmap.
+
+The composer redesign moves paging into the footer next to the actions, renders multi-select options with explicit checkboxes, keeps single-select numbered rows, and replaces the expand-to-open custom entry with an always-visible custom input row (textarea for optionless questions). The `parseQuestionTitle` multi-select suffix convention is deleted; `multi_select` is already structured metadata, so the title renders verbatim.
+
+Composer chrome copy becomes bilingual: the plugin registers zh/en dictionaries under the `question` namespace of `dsh-client-locale` and hands the entry a namespace-bound translator plus the locale snapshot as a hooks-compartment source through the slot inject face, so a locale flip re-renders a mounted composer. Validation feedback is stored as a dictionary key and re-translated on flip; carrier failure messages and all model-authored question/option text render verbatim.
+
+Two adjacent fixes ride along. All generic toolview leading icons (and the hover chevron) now inherit the single tertiary label color — the others-variant secondary override and the separate chevron color rule are deleted, leaving only the intentional cordis business-primary accent. And the client dev-watch bundler registers each CSS module with `addWatchFile`, because the virtual-module indirection previously hid css-only edits from the watcher.
+
+## Alternatives considered
+
+**Keep rendering questions through `PendingCard`.** Rejected: the card was a read-only placeholder from before the takeover existed, so a pending question showed the same content twice with one copy not answerable. The toolview row plus takeover covers both the transcript record and the collection surface.
+
+**Show the questions or answers inline in the transcript row.** Rejected: the composer takeover owns question rendering and answer collection, and the row convention (`todo_write`) is one line with details in the panel. The row therefore reports only the outcome, mirroring how the todo row reports counts while the panel owns the list.
+
+**Render `ASK_CANCELLED`/`ASK_ABORTED` through the generic error shape.** Rejected: dismissal is the user's own deliberate action and an interrupt is the shared stop gesture; both are expected outcomes, not tool failures. Naming the verdict (and keeping amber stopped semantics for the abort) matches how interrupted tool calls read elsewhere.
+
+**Translate the row verdicts now.** Deferred by explicit product decision: the row's `waiting`/`answered`/`cancelled`/`interrupted` strings stay English for this change; the composer chrome i18n landed because its Chinese-only copy was already wrong for the en locale.
+
+**Keep the title-suffix multi-select convention.** Rejected: `multi_select` is structured request metadata and the checkbox affordance now carries the signal, so parsing `（可多选）` out of model text was a fragile duplicate channel.
+
+## Consequences
+
+`ask_user_question` and `todo_write` now demonstrate the intended toolview pattern: compose `ToolRow`, summarize from call args or result JSON with shape-checked fallbacks, and register through the keyed slot. The bespoke `todo-row.module.css` is gone.
+
+The row verdict strings are the one remaining hardcoded-English surface of the question flow; localizing them is deferred follow-up. `PendingCard` remains a visible-but-not-answerable approval placeholder until the approval composer takeover ships.
+
+`ui-question` gains a `dsh-client-locale` dependency and an inject face where it previously had none; its contract (`QuestionComposerInjected`) lives with the consumer in `contract/slots.ts`.
+
+## Verification
+

+# Agent Note：Ask-question Web 呈现
+
+Status: implemented
+
+[English](2026-07-29-ask-question-web-presentation.md) | 中文
+
+## 问题
+
+Web GUI 已经可以通过 `QuestionComposer` 的输入区接管收集回答，但其周边的会话记录呈现在三个方面是错的。待回答的问题会渲染两次：一次是输入区接管，一次是早于接管存在的只读 `PendingCard` 占位卡片。已结算的 `ask_user_question` 调用渲染为通用 "Tool call" 行并直接倾倒原始 args JSON，因此两种输入区裁决 —— 用户放弃整组问题（`ASK_CANCELLED`）与问题待回答期间轮次被打断（`ASK_ABORTED`）—— 都显示为无名的红点失败。而且输入区自身的界面文案（分页、按钮、占位符、校验反馈）是硬编码中文，而周边客户端已通过 `dsh-client-locale` 实现双语。
+
+另外，输入区视觉也偏离了当前设计：自定义回答需展开才能输入、多选除尾部对勾外没有可见标识、分页挂在头部、还有从模型文本里解析 `（可多选）` 标题后缀的约定。
+
+## 决定
+
+一个待回答的问题恰好拥有两个界面：输入区接管收集回答，会话记录中一个专门的 `ask_user_question` toolview 行陈述交互结果。该行与 `todo_write` 完全一样注册进带 key 的 `conversation.chat.toolview` 槽位，并复用共享的 `ToolRow`（外观、运行扫光、前导展开）。其摘要是交互裁决而非参数：运行中显示 `waiting`，结算后从结果 JSON 得出 `N/M answered`（被跳过的回答 —— `selected` 为空且无 `custom` —— 不计入），`ASK_CANCELLED` 显示 `cancelled`，`ASK_ABORTED` 显示 `interrupted` 并沿用共享的琥珀色 stopped 语义。畸形或截断的结果回退到通用摘要。`PendingCard` 收窄为 `PendingWait<'approval'>`，`ChatView` 将待处理列表过滤为仅审批等待，占位卡片从此只服务于仍在路线图上的审批接管。
+
+输入区重设计将分页移到底部操作区旁，多选选项渲染显式复选框，单选保留编号行，并用始终可见的自定义输入行取代展开式自定义入口（无选项问题用多行文本框）。删除 `parseQuestionTitle` 的多选后缀约定；`multi_select` 已是结构化元数据，标题原样渲染。
+
+输入区界面文案实现双语：插件在 `dsh-client-locale` 的 `question` 命名空间下注册中英词典，并通过槽位 inject face 向条目提供绑定命名空间的翻译器和作为 hooks 舱源的 locale 快照，语言切换时已挂载的输入区会重新渲染。校验反馈以词典 key 存储、切换时重新翻译；载体失败消息与所有模型撰写的问题/选项文本原样渲染。
+
+两个相邻修复随行。所有通用 toolview 前导图标（含悬停箭头）现在统一继承三级标签色 —— 删除了 others 变体的二级色覆盖和独立的箭头颜色规则，只保留有意为之的 cordis 业务主色强调。客户端 dev-watch 打包器用 `addWatchFile` 注册每个 CSS 模块，因为虚拟模块间接层此前使仅改 CSS 的编辑对 watcher 不可见。
+
+## 曾考虑的替代方案
+
+**继续通过 `PendingCard` 渲染问题。** 否决：该卡片是接管存在之前的只读占位，导致同一内容显示两份且其中一份不可作答。toolview 行加接管同时覆盖了记录与收集两个面。
+
+**在会话记录行内联显示问题或回答。** 否决：输入区接管拥有问题渲染与回答收集，而行的约定（`todo_write`）是单行、详情在面板。因此行只报告结果，正如 todo 行报告计数而面板拥有列表。
+
+**用通用错误形态渲染 `ASK_CANCELLED`/`ASK_ABORTED`。** 否决：放弃是用户自己的主动操作，打断是共享的停止手势；两者都是预期结果而非工具失败。命名裁决（且中止保持琥珀色 stopped 语义）与其他被打断的工具调用的呈现一致。
+
+**现在就翻译行内裁决文案。** 依明确的产品决定推迟：本次改动中行的 `waiting`/`answered`/`cancelled`/`interrupted` 字符串保持英文；输入区界面文案的国际化落地是因为其仅中文的文案在 en 语言下本就是错的。
+
+**保留标题后缀的多选约定。** 否决：`multi_select` 是结构化请求元数据且复选框标识已承载该信号，从模型文本解析 `（可多选）` 是脆弱的重复通道。
+
+## 后果
+
+`ask_user_question` 与 `todo_write` 现在共同示范预期的 toolview 模式：复用 `ToolRow`、从调用参数或结果 JSON 做带形状校验回退的摘要、通过带 key 的槽位注册。专用的 `todo-row.module.css` 已删除。
+
+行内裁决字符串是问题流程仅剩的硬编码英文面；将其本地化是推迟的后续工作。在审批输入区接管交付之前，`PendingCard` 仍是可见但不可操作的审批占位。
+
+`ui-question` 新增 `dsh-client-locale` 依赖和此前没有的 inject face；其契约（`QuestionComposerInjected`）与消费者一起放在 `contract/slots.ts`。
+
+## 验证
+
+`ui-conversation` 测试钉住行的 waiting/answered/skipped/cancelled/interrupted/回退矩阵、仅审批的待处理过滤和槽位注册；`ui-question` 测试钉住重设计的输入区（复选框多选、始终可见的自定义行、底部分页、词典 key 反馈重翻译、IME 安全的 Enter）以及插件的词典注册与 inject face；`ui-primitives` 测试钉住图标集。组装后的 Web GUI 在真实会话中演练了回答、取消与轮次打断路径。

 Selection state is local to a component keyed by the request rpcId. A replay with the same id preserves a still-mounted draft, while `question/resolved` from the host removes the composer. The host remains authoritative: successful HTTP delivery does not remove pending state locally.
 
+Composer chrome copy (pager, buttons, placeholders, validation feedback) is bilingual: the plugin registers zh/en dictionaries under the `question` namespace of `dsh-client-locale` and hands the entry its bound translator plus the locale snapshot source through the inject face, so a locale switch re-renders a mounted composer. Question and option text arrives from the model and renders verbatim; carrier failure messages also display untranslated.

 Indirectly, through `dsh-tool-ask-user`; that package owns the model-visible tool schema and structured result.

+# Agent Note: Persistent Bash and string-replacement editor tools
+
+Status: implemented
+
+English | [中文](2026-07-29-persistent-bash-str-replace-editor.zh.md)
+
+## Problem
+
+Some deployments need a one-call Bash schema whose shell state survives across model turns, while others need a Claude-style `str_replace_editor` independent of their terminal choice. Bundling the two tools or naming them after one benchmark would prevent reuse and blur configuration ownership.
+
+## Decision
+
+`@deepseek-ai/dsh-tool-bash-persistent` consumes `ctx.pty` and registers one `bash(command)` tool. It lazily creates one interactive shell per exact Agent and serializes that owner's calls. Cwd, exported variables, activated environments, functions, and background jobs persist. Random private markers delimit command output. Retained scrollback is paged backward to recover the command's original prefix; a dropped prefix is reported explicitly. Timeout or cancellation closes the shell before another call can reuse uncertain state, and model-visible timeout/exit results disclose that reset. The configurable description defaults to persistence facts only, so network and package-mirror claims remain deployment-owned.
+
+`@deepseek-ai/dsh-tool-str-replace-editor` independently consumes `ctx.fs` and registers `str_replace_editor` with `view`, `create`, `str_replace`, and `insert`. It provides numbered text views, filtered two-level directory listings, unique literal replacement, canonical insertion boundaries, and bounded output. The public schema and failures use only `old_str`; canonical mode requires absolute paths and expands tabs before mutations. Deployments with an intentional session-cwd contract can disable the absolute-path requirement. The plugin can compose with persistent Bash, one-shot Bash, sandboxed Bash, or no shell.
+
+`dsh-system-prompt` accepts `includeHarnessIdentity: false`, while `dsh-agent-spine-demo` forwards that setting and accepts `toolBash: false`. A deployment can therefore own an exact persona and replace the spine's native Bash without duplicate prompt or tool registrations. Existing defaults remain unchanged.
+
+Both plugins are included in the Python runtime closure. The persistent Bash closure also includes the PTY service/local backend and the sandbox services required by that backend. Because `node-pty` executes a native `spawn-helper`, each packaged runtime executable ships with an architecture-matched `-spawn-helper` sibling. A pinned `node-pty` patch resolves that sibling only when present (or when `DSH_NODE_PTY_SPAWN_HELPER` explicitly selects one), preserving upstream lookup in ordinary Node runs; the executable and runtime-wheel builders fail before publication when the helper is absent, mismatched, or not executable.
+
+## Alternatives considered
+
+**One combined compatibility plugin.** Rejected because neither tool requires the other and the combined name would tie reusable capabilities to one benchmark.
+
+**Reuse one-shot Bash.** Rejected because `bash -c` cannot preserve cwd or environment state across calls.
+
+**Expose terminal management tools.** Rejected because open/send/read/close is a different model action space from one persistent `bash` call.
+
+**Modify native read/write/edit.** Rejected because it would distort their general-purpose contracts instead of adding an independently composable editor.
+
+## Consequences
+
+Profiles can reproduce an external agent by configuring persona and descriptions while the underlying packages remain general. Persistent Bash requires an owning Agent and real PTY backend. Shell exit, timeout, or cancellation loses state. The editor delegates security and mutation policy to the mounted filesystem stack. Runtime-wheel consumers still need no Node installation, but the wheel now contains a main executable plus its private native helper rather than one physical file.

+# Agent Note：持久 Bash 与字符串替换编辑器工具
+
+状态：已实现
+
+[English](2026-07-29-persistent-bash-str-replace-editor.md) | 中文
+
+## 问题
+
+部分部署需要只调用一次的 Bash schema，同时要求 shell 状态跨模型轮次保留；另一些部署需要与终端选择无关的 Claude 风格 `str_replace_editor`。把两个工具绑在一起或按某个基准命名，会阻碍复用并模糊配置归属。
+
+## 决策
+
+`@deepseek-ai/dsh-tool-bash-persistent` 消费 `ctx.pty` 并注册一个 `bash(command)` 工具。它为每个精确 Agent 惰性创建一个交互式 shell，并串行化该所有者的调用。Cwd、导出的变量、已激活环境、函数和后台任务会保留。随机私有标记划分命令输出；保留的 scrollback 会向前分页，以恢复命令真正的输出前缀，若前缀已被丢弃则明确告知。超时或取消会先关闭 shell，避免下一次调用复用状态不确定的会话，模型可见的超时／退出结果也会说明该重置。可配置描述默认只声明持久性事实，因此网络和软件包镜像等声明仍归部署所有。
+
+`@deepseek-ai/dsh-tool-str-replace-editor` 独立消费 `ctx.fs`，注册包含 `view`、`create`、`str_replace` 与 `insert` 的 `str_replace_editor`。它提供带行号文本查看、过滤后的两层目录列表、唯一字面量替换、规范插入边界和有界输出。公开 schema 与错误只使用 `old_str`；规范模式要求绝对路径，并在变更前展开制表符。有明确 session-cwd 契约的部署可以关闭绝对路径要求。它可以与持久 Bash、一次性 Bash、沙箱 Bash 或无 shell 组合。
+
+`dsh-system-prompt` 接受 `includeHarnessIdentity: false`；`dsh-agent-spine-demo` 会转发该设置，并接受 `toolBash: false`。因此部署可以拥有精确 persona，并替换 spine 的原生 Bash，而不会重复注册提示词或工具。既有默认值不变。
+
+两个插件都进入 Python runtime 闭包。持久 Bash 的闭包还包含 PTY 服务／本地后端，以及该后端要求的沙箱服务。由于 `node-pty` 会执行原生 `spawn-helper`，每个打包后的运行时可执行文件都会携带一个架构匹配的 `-spawn-helper` 伴随文件。固定版本的 `node-pty` 补丁只在该伴随文件存在时解析它（也可由 `DSH_NODE_PTY_SPAWN_HELPER` 显式指定），普通 Node 运行仍保留上游查找方式；若 helper 缺失、架构不匹配或不可执行，可执行文件与 runtime wheel 构建会在发布前失败。
+
+## 考虑过的替代方案
+
+**单一组合兼容插件。** 被拒绝，因为两个工具互不依赖，组合命名还会把可复用能力绑定到某个基准。
+
+**复用一次性 Bash。** 被拒绝，因为 `bash -c` 无法跨调用保留 cwd 或环境状态。
+
+**暴露终端管理工具。** 被拒绝，因为 open/send/read/close 与单个持久 `bash` 调用是不同的模型动作空间。
+
+**修改原生 read/write/edit。** 被拒绝，因为这会扭曲其通用契约，而不是增加一个可独立组合的编辑器。
+
+## 后果
+
+Profile 可以通过配置 persona 和描述复现外部 Agent，而底层包保持通用。持久 Bash 需要拥有它的 Agent 与真实 PTY 后端；shell 退出、超时或取消会丢失状态。编辑器把安全与变更策略委托给挂载的文件系统栈。runtime wheel 的使用者仍不需要安装 Node，但 wheel 现在包含主可执行文件及其私有原生 helper，而不是单个物理文件。

Absent ⇒ plain lexicographic name order. Applied to the collected tools BEFORE the `system-prompt/assemble` waterfall — like the sections' `order` sort, it canonicalizes what the registry contributed (registration order is a plugin-load artifact), and a waterfall listener that mutates the list owns the determinism of what it emits. Misconfiguration fails loud: a list without exactly one rest entry, or with duplicates, throws at load; a listed name with no registered tool rejects every `assemble()`; a tool provider returning the reserved rest-entry name also rejects. Under the shipped loop the turn fails before any model request.

 The interface lives at `fs/fs/`. A sandboxed, remote, or project-scoped filesystem backend can replace `fs-local` without touching the seam, the policy gate, or the model-facing tool schemas — `fs-sandbox` is the first such replacement (an in-process path fence over the shared sandbox mode; see [the cross-family fs sandbox Agent Note](../../.agents/notes/implemented/feature/2026-07-14-cross-family-fs-sandbox.md)). The policy (`fs-policy/`) is a plugin that participates only through the `fs/*` event gate, not a service the tool injects — so dropping it gracefully loses the policy and leaves the unconstrained bare provider rather than breaking the tool. A deployment that loads `tool-fs/` is expected to also load it. The mode fence and the read-before-edit gate are orthogonal and compose. Discovery (`tool-fs-search/`) deliberately does NOT extend the provider seam: search is a process-backed `rg` workflow on the bash executor, so filesystem backends stay free of a universal search contract; its tools register only when that executor can find `rg`, and its results are follow-up-readable when the bash workdir and the `read` root are the same workspace (the co-located deployment its README documents).

+
+## Tool
+
+The schema provides `view`, `create`, `str_replace`, and `insert`. File views use one-based line numbers; directory views omit hidden, dependency, and Python-cache entries and descend two levels. Replacement requires one unique literal match and reports errors only in the public `old_str` vocabulary. Insert follows the selected zero-based insertion boundary without adding an implicit trailing newline.
+
+## Model Experience
+
+### Tool schema
+
+#### What the model sees
+
+The generated [`str_replace_editor` schema](../../../docs/tool-catalog.md#deepseek-aidsh-tool-str-replace-editor), including the configured `description`. The plugin contributes no standalone system-prompt section.
+
+#### Token effect
+
+Fixed schema cost while `str_replace_editor` is visible.
+
+#### KV Cache effect
+
+Prefix-stable while the configured description and schema remain unchanged.
+
+### Tool results
+
+#### What the model sees
+
+Views return numbered text or a shallow directory listing. Mutations return concise confirmations. Long views keep their prefix and append a clipping notice.
+
+#### Token effect
+
+Data-dependent and bounded by `maxOutputChars` plus the fixed clipping notice.
+
+#### KV Cache effect
+
+Append-only tool results follow the reusable request prefix.
+
+## Known Limitations and Deferred Work
+
+- Operations target UTF-8 text; binary files are unsupported.
+- `str_replace` intentionally rejects zero or multiple matches and has no `replace_all` argument.
+- Canonical mode expands tabs before replacement or insertion, matching the reference string-replacement editor.
+- The package delegates security and read-before-edit policy to the mounted filesystem and policy plugins.

+# @deepseek-ai/dsh-tool-str-replace-editor
+
+[English](README.md) | 中文
+
+基于 `ctx.fs` 的独立模型可见 `str_replace_editor`。它可与持久 Bash、一次性 Bash、沙箱 Bash 或其他终端表面组合。
+
+## 配置
+
+| 键 | 默认值 | 含义 |
+|---|---:|---|
+| `maxOutputChars` | `16000` | 文件和目录查看结果保留的前缀字符数。 |
+| `description` | 编辑器命令指南 | 面向模型的工具描述。 |
+| `requireAbsolutePath` | `true` | 拒绝相对路径；仅当部署明确约定 session cwd 时才应关闭。 |
+
+## 工具
+
+Schema 提供 `view`、`create`、`str_replace` 与 `insert`。文件查看使用从一开始的行号；目录查看忽略隐藏、依赖与 Python 缓存条目并下探两层。替换要求字面量唯一匹配，错误只使用公开的 `old_str` 词汇。插入遵循所选的零基插入边界，不会隐式补尾换行。
+
+## 模型体验
+
+### 工具 schema
+
+#### 模型所见
+
+生成的 [`str_replace_editor` schema](../../../docs/tool-catalog.md#deepseek-aidsh-tool-str-replace-editor)，其中包含配置的 `description`。本插件不贡献独立系统提示词段。
+
+#### Token 影响
+
+`str_replace_editor` 可见时产生固定的 schema 成本。
+
+#### KV Cache 影响
+
+配置的描述与 schema 不变时前缀稳定。
+
+### 工具结果
+
+#### 模型所见
+
+查看操作返回带行号文本或浅层目录列表。修改操作返回简洁确认。长查看结果保留前缀并追加截断提示。
+
+#### Token 影响
+
+随数据变化，并受 `maxOutputChars` 与固定截断提示约束。
+
+#### KV Cache 影响
+
+工具结果以追加方式位于可复用请求前缀之后。
+
+## 已知限制与延后工作
+
+- 操作面向 UTF-8 文本，不支持二进制文件。
+- `str_replace` 刻意拒绝零匹配或多匹配，且没有 `replace_all` 参数。
+- 规范模式会在替换或插入前展开制表符，与参考字符串替换编辑器保持一致。
+- 安全与先读后改策略委托给挂载的文件系统和策略插件。

+Model-facing `bash(command)` backed by one owner-scoped `ctx.pty` shell. The package owns the tool contract and shell reuse; deployments select the PTY backend and sandbox policy.
+
+## Config
+
+| Key | Default | Meaning |
+|---|---:|---|
+| `backendType` | `shell` | Registered PTY backend used for each Agent shell. |
+| `timeoutMs` | `300000` | Wall-clock limit for one command; timeout closes the shell. |
+| `maxOutputChars` | `16000` | Prefix characters retained before the clipping notice. |
+| `description` | Persistent-shell description | Model-facing environment contract. |
+
+## Model Experience
+
+### Tool schema
+
+#### What the model sees
+
+The generated [`bash` schema](../../../docs/tool-catalog.md#deepseek-aidsh-tool-bash-persistent), including the configured `description`. The plugin contributes no standalone system-prompt section; the deployment owns persona and environment guidance.
+
+#### Token effect
+
+Fixed schema cost while `bash` is visible.
+
+#### KV Cache effect
+
+Prefix-stable while the configured description and schema remain unchanged.
+
+### Tool results
+
+#### What the model sees
+
+Commands share one shell per Agent, so cwd, exported variables, activated environments, functions, and background jobs persist across calls. Results exclude private completion markers and the shell prompt. Long output keeps the earliest retained prefix plus a clipping notice. If the PTY has already dropped that prefix, the result says so explicitly instead of presenting a tail as complete output. Timeout returns bounded partial output, closes the uncertain shell, and tells the model that the next call starts fresh.
+
+#### Token effect
+
+Data-dependent and bounded by `maxOutputChars` plus the fixed clipping notice.
+
+#### KV Cache effect
+
+Append-only tool results follow the reusable request prefix.
+
+## Known Limitations and Deferred Work
+
+- The tool requires an owning Agent and a real PTY backend.
+- Explicit `exit`, timeout, or cancellation discards shell state; the next call starts a fresh shell.
+- Environment facts such as network access and package mirrors belong in the configured `description`, not this package's default.

+# @deepseek-ai/dsh-tool-bash-persistent
+
+[English](README.md) | 中文
+
+模型可见的 `bash(command)`，底层复用一个按所有者隔离的 `ctx.pty` shell。该包拥有工具契约和 shell 复用；PTY 后端与沙箱策略由部署选择。
+
+## 配置
+
+| 键 | 默认值 | 含义 |
+|---|---:|---|
+| `backendType` | `shell` | 每个 Agent shell 使用的已注册 PTY 后端。 |
+| `timeoutMs` | `300000` | 单条命令的墙钟时间上限；超时会关闭 shell。 |
+| `maxOutputChars` | `16000` | 截断提示前保留的前缀字符数。 |
+| `description` | 持久 shell 描述 | 面向模型的环境契约。 |
+
+## 模型体验
+
+### 工具 schema
+
+#### 模型所见
+
+生成的 [`bash` schema](../../../docs/tool-catalog.md#deepseek-aidsh-tool-bash-persistent)，其中包含配置的 `description`。本插件不贡献独立系统提示词段；persona 与环境指导由部署负责。
+
+#### Token 影响
+
+`bash` 可见时产生固定的 schema 成本。
+
+#### KV Cache 影响
+
+配置的描述与 schema 不变时前缀稳定。
+
+### 工具结果
+
+#### 模型所见
+
+每个 Agent 的命令共享一个 shell，因此 cwd、导出的环境变量、已激活环境、函数和后台任务会跨调用保留。结果不包含私有完成标记和 shell 提示符。长输出保留仍可读取的最早前缀并追加截断提示；若 PTY 已丢弃真正的开头，结果会明确说明，而不是把尾部伪装成完整输出。超时返回有界的部分输出、关闭状态不确定的 shell，并告知模型下次调用从新 shell 开始。
+
+#### Token 影响
+
+随数据变化，并受 `maxOutputChars` 与固定截断提示约束。
+
+#### KV Cache 影响
+
+工具结果以追加方式位于可复用请求前缀之后。
+
+## 已知限制与延后工作
+
+- 工具需要拥有它的 Agent 和真实 PTY 后端。
+- 显式 `exit`、超时或取消会丢弃 shell 状态；下次调用创建新 shell。
+- 网络访问、软件包镜像等环境事实应写入配置的 `description`，而非包默认描述。

 Two carriers coexist under `src/deepseek_harness_runtime/runtime/`, both injected by the repo's `scripts/build-exe-for-python-sdk.ts` build and both gitignored:
 
-- **exe (production)** — single-file executables `dsh-jsonrpc-agent-pkg-<platform>-<arch>` (platform: `linux`/`macos`; arch: `x64`/`arm64`). No Node installation needed on the target machine. This is the only carrier that ships in wheel distributions; this package does not publish sdists.
+- **exe (production)** — a single-file Node executable `dsh-jsonrpc-agent-pkg-<platform>-<arch>` plus its native `-spawn-helper` sibling (platform: `linux`/`macos`; arch: `x64`/`arm64`). The helper is required by `node-pty`; both files are built and validated as one runtime product. No Node installation is needed on the target machine. This is the only carrier that ships in wheel distributions; this package does not publish sdists.
 - **node (dev-only)** — the full deploy closure under `runtime/node/` (`package.json` + `node_modules/`), executed as `node runtime/node/node_modules/@deepseek-ai/dsh-jsonrpc-demo/lib/bin.js` on a system Node >= 22.19. It is the current checkout's source build, meant for repo-local development and verification only; it is never selected automatically and is excluded from distributions.
 
 Both carriers hold the same content, defined once: the [package.json](package.json) at this package's root is the deploy root of the single-exe pipeline — a pure dependency manifest (no code of its own) whose dependency closure IS both the plugin set compiled into the exe and the tree materialized into `runtime/node/`. Adding a plugin to the distribution means adding one dependency line there and rebuilding.
 
 A missing exe raises `FileNotFoundError` naming both acquisition routes: build via `scripts/build-exe-for-python-sdk.ts` in a deepseek-harness checkout, or install the matching platform runtime wheel produced by the `build-exe-for-python-sdk` CI workflow. A missing dev-only node carrier names its sole route, the build script. The workflow retains wheels rather than standalone executable archives. Acquisition strategy is deliberately separate from the lookup interface, so an on-demand download can replace it later without touching callers.
 
-Each wheel contains exactly one executable. The fixed tags are `py3-none-manylinux_2_28_x86_64`, `py3-none-manylinux_2_28_aarch64`, and `py3-none-macosx_11_0_arm64`; the build hook rejects `py3-none-any`, absent or multiple executables, and unsupported platform tags. The repository root `package.json` supplies the shared version for this package and the SDK, and a `python-vX.Y.Z` release tag must match it.
+Each wheel contains exactly one runtime executable and its matching native spawn helper.

The repository root `package.json` supplies the shared version for this package and the SDK, and a `python-vX.Y.Z` release tag must match it.
 
 ## Resolution API
 
 - `resolve_bundled_launch_args(mode=None) -> tuple[str, ...]` — the argv tuple that launches the bundled runtime: `(exe_path,)` in exe mode, `(node_path, bin_js_path)` in node mode. Mode selection: explicit argument > `DSH_RUNTIME_MODE` env var (`exe` | `node`) > automatic. Automatic resolution finds the production exe ONLY — the dev-only node carrier must be opted into explicitly so a production deployment can never silently ride on a source build.
-- `bundled_runtime_path() -> Path` — the platform exe path (exe carrier only; the node carrier has no single-path equivalent and launches via the argv tuple above).
+- `bundled_runtime_path() -> Path` — the platform exe path (exe carrier only; it validates that the required sibling `-spawn-helper` is also installed). The node carrier has no single-path equivalent and launches via the argv tuple above.

 两种载体并存于 `src/deepseek_harness_runtime/runtime/` 之下，均由仓库的 `scripts/build-exe-for-python-sdk.ts` 构建注入，且均被 git 忽略：
 
-- **exe（生产）**——单文件可执行程序 `dsh-jsonrpc-agent-pkg-<platform>-<arch>`（platform：`linux`/`macos`；arch：`x64`/`arm64`）。目标机器无需安装 Node。这是唯一随 wheel 包分发的载体；本包不发布 sdist。
+- **exe（生产）**——单文件 Node 可执行程序 `dsh-jsonrpc-agent-pkg-<platform>-<arch>` 及其原生 `-spawn-helper` 伴随文件（platform：`linux`/`macos`；arch：`x64`/`arm64`）。`node-pty` 需要该 helper；构建与校验会把两者视作同一个运行时产物。目标机器无需安装 Node。这是唯一随 wheel 包分发的载体；本包不发布 sdist。
 - **`node`（仅限开发）**——`runtime/node/` 下的完整部署闭包（`package.json` + `node_modules/`），在系统 Node >= 22.19 上以 `node runtime/node/node_modules/@deepseek-ai/dsh-jsonrpc-demo/lib/bin.js` 执行。它是当前检出的源码构建，仅用于仓库本地的开发与验证；不会被自动选中，也不进入分发物。
 
 两种载体承载相同的内容，且只定义一次：本包根目录的 [package.json](package.json) 是 single-exe 流水线的部署根目录——一份零代码的纯依赖 manifest，其依赖闭包既是编译进 exe 的插件集，也是物化到 `runtime/node/` 的文件树。往分发物里加插件，就是在那里加一行依赖再重新构建。
 
 exe 缺失时抛出 `FileNotFoundError`，并写明两种获取途径：在 deepseek-harness 检出中经 `scripts/build-exe-for-python-sdk.ts` 构建，或安装 `build-exe-for-python-sdk` CI 工作流生成的对应平台运行时 wheel 包。仅限开发的 `node` 载体缺失时只提示构建脚本这一条途径。该工作流只保留 wheel 包，不保留独立 exe 归档。获取策略与查找接口刻意分离，之后可以换成按需下载而不改动任何调用方。
 
-每个 wheel 包只包含一个可执行文件。固定标签为 `py3-none-manylinux_2_28_x86_64`、`py3-none-manylinux_2_28_aarch64` 与 `py3-none-macosx_11_0_arm64`；构建钩子会拒绝 `py3-none-any`、可执行文件缺失或重复以及不支持的平台标签。仓库根目录的 `package.json` 为本包和 SDK 提供共同版本，`python-vX.Y.Z` 发布标签必须与其匹配。

 ## 解析 API
 
 - `resolve_bundled_launch_args(mode=None) -> tuple[str, ...]`——启动内置运行时的 argv 元组：exe 模式下为 `(exe_path,)`，`node` 模式下为 `(node_path, bin_js_path)`。模式选择：显式参数 > `DSH_RUNTIME_MODE` 环境变量（`exe` | `node`）> 自动。自动解析只找生产 exe——仅限开发的 `node` 载体必须显式选用，从而生产部署绝不会悄悄跑在源码构建上。
-- `bundled_runtime_path() -> Path`——平台 exe 路径（仅 exe 载体；`node` 载体没有单一路径的等价物，经由上面的 argv 元组启动）。
+- `bundled_runtime_path() -> Path`——平台 exe 路径（仅 exe 载体，并会校验必要的 `-spawn-helper` 伴随文件也已安装）。`node` 载体没有单一路径的等价物，经由上面的 argv 元组启动。
 - `bundled_default_config_path() -> Path`——检入的默认配置（见下文）。
 - `bundled_package_dir() -> Path`——已安装包的数据根目录。

 Behavior facts: listings return **directories only**, name-sorted, with symlinks-to-directories followed (broken/cyclic links skipped — the probe `stat` failing means "not enterable") and a host-owned `hidden` flag (POSIX dot convention) left for the client to act on; `crumbs` is the root-to-target ancestor chain, the root crumb labeled by its full path (`/`, `C:\`); an absent `list` path means the host account's home directory. `createDirectory` is non-recursive (a missing parent is a real failure, not a level to invent) and validates the name as a single non-blank segment even when called directly, mirroring the wire schema's fence. Both primitives reject an explicit path that is not fully qualified — relative forms, and on Windows the rooted drive-less forms (`\foo`, `/foo`) and incomplete UNC prefixes (`\\`, `\\server`) that `isAbsolute` accepts — with `directory-unreadable`/`directory-create-failed`, instead of letting `resolve` rebase it under the host process cwd or current drive. One `list` call returns at most `maxEntries` rows (config, default 1000 — the bound GitHub's web UI applies to directory listings), and the level streams through a bounded window so memory stays O(maxEntries) no matter how many children the directory holds: a cut level keeps the name-sorted head, counts hidden rows against the bound, probes only windowed candidates, and reports `truncated: true` so the client can say the level is incomplete (a windowed broken symlink is not backfilled from beyond the window — the eviction already marks the level truncated); window insertion is binary with an O(1) full-window tail rejection, and `list` threads the caller's `AbortSignal` so a disconnect or timeout stops the scan instead of letting it outlive the caller. Failures throw the seam's typed `DirectoryPickerError`. Policy rationale: [the directory-picker capability seam Agent Note](../../../.agents/notes/implemented/architecture/2026-07-28-directory-picker-capability-seam.md).

One cordis.yml row therefore composes both sides of the browse interaction; the client carries no capability-kind branching, and mounting a second flow package fails at load (the holes are `single` kind).

@@ -18,7 +18,8 @@ Placement and policy rulings folded into this decision:
 
 - **Not the `ctx.fs` seam.** `packages/fs/` is the model/session-facing storage stack (policy events, sandbox-swappable backends). Riding it would couple GUI browsing to the model's confinement backend — swapping `fs-sandbox` for the model must never change GUI behavior — and OS facts (home anchoring, hidden conventions) are not storage primitives. The picker seam stays presentation-free and model-free; `packages/host/` is its consumer-domain home.
 - **Dependency survey (hand-roll vs adopt).** Node's stdlib *is* the maintained cross-platform OS layer (`readdir(withFileTypes)`, `homedir`, path semantics); surveyed alternatives fail the dependency bar — file-manager packages (`node-file-manager`, `files-and-folders`, Syncfusion's provider) are whole HTTP apps (fit), drive-letter helpers (`drivelist` native addon, `windows-drive-letters` ~7y stale) fail health/proportionality. The browse backend is a thin adapter over stdlib.
-- **Hidden entries: return-and-flag.** The host stamps `hidden` (POSIX dot convention) and returns everything; the client filters. Display policy stays client-side, and the show-hidden toggle shipped as exactly that client-only change (the browse client's footer toggle). Windows' `FILE_ATTRIBUTE_HIDDEN` is not exposed by dirents — documented limitation until a native probe pays for itself.
+- **Hidden entries: return-and-flag.** The host stamps `hidden` (POSIX dot convention) and returns everything; the client filters. Display policy stays client-side, and the show-hidden toggle shipped as exactly that client-only change: a fixed-label footer toggle whose state lives in the pressed presentation (`aria-pressed` + check glyph), a dot-led path-draft prefix reveals the hidden entries it names, and the current selection is exempt from both the hidden and the prefix filter (it anchors the two-pane view). Windows' `FILE_ATTRIBUTE_HIDDEN` is not exposed by dirents — documented limitation until a native probe pays for itself.
+- **Path-editor cancel scope: the dialog card.** The browse client's path editor cancels on Escape and on focus leaving the card, both observed at a card-scope wrapper rather than the input — after Tab parks focus on a filtered row the input is off the event path, yet Escape must collapse the editor (not the dialog) and a later focus departure must still cancel. Non-cancel exemptions: window/tab focus loss, in-card focus moves, and pointer paths (rows and the toggle suppress focus steal on mousedown while editing). Separators for seeding and draft-tail filtering are inferred from `listing.home`; the wire-field alternative below records the deferred authoritative form.
 - **Symlinks: follow for enterability.** `stat` probes symlinks (broken/cyclic → skipped); crumbs keep the logical path the operator navigated, and `workspace.create` already canonicalizes via realpath at adoption.
 - **Listing levels are bounded, and streamed.** One `list` call returns at most `maxEntries` rows (config, default 1000 — GitHub's web-UI directory-listing bound). The level streams via `opendir` into a name-sorted window of `maxEntries + 1` candidates, so memory stays O(maxEntries) and enterability probing touches only windowed candidates; the wire `DirectoryListing` carries a required `truncated` flag so the client states incompleteness instead of silently missing tail entries. A windowed broken symlink is not backfilled from beyond the window — the eviction already marks the level truncated. Window insertion is binary with an O(1) full-window tail rejection (an oversized level must not pay a window scan per dirent), and `list(path, signal)` threads the carrier's request signal so a scan of a stalled network directory cannot outlive a disconnected caller — every await in the scan (open, each read, each symlink probe) races the signal, an aborted exit abandons rather than awaits the close (Node queues close behind in-flight reads), and abandoned settlements are swallowed so cleanup can never surface as an unhandled rejection. An unbounded level is a memory/responsiveness hole for large or adversarial directories.
 - **Whole-filesystem scope, no roots config.** `workspace.create` accepts arbitrary paths and the API serves bash-driving methods, so a browse root would be UX scoping, not a boundary; configurability without a consumer fails the evidence bar. Deferred until a deployment needs it.
@@ -30,6 +31,9 @@ Placement and policy rulings folded into this decision:
 - **One uniform seam method set (`pick(): path`).** Rejected: an in-app browser cannot be served behind a single host-side call — the browsing loop lives in the client and needs primitives on the wire; the native chooser cannot implement primitives. The interaction difference is irreducible, hence the discriminant.
 - **Direct stdlib calls inside apiproxy (no seam).** Rejected: keeps the gateway the only swap point (source edits), loses fixture/test backends, and contradicts the plugin doctrine that motivated the work.
 - **Adopting a file-manager/drive-enumeration dependency.** Rejected per the survey above; recorded here as the dependency policy requires.
+- **A flip-label show-hidden toggle ("Hide hidden files").** Rejected: a flipping action label is ambiguous between state and action and doubles the negative; the fixed label with a pressed presentation states both at once.
+- **Pure relatedTarget blur cancellation (no mousedown suppression).** Rejected: Safari does not focus buttons on pointer down, so a click's focusout carries a null `relatedTarget` and would cancel the editor before the click lands; editing-scoped mousedown suppression plus the card-anchored relatedTarget guard covers pointer and keyboard paths together.
+- **A wire `separator` field on `DirectoryListing` (host stamps `path.sep`).** Deferred, not rejected: it is the authoritative form — a POSIX home directory containing a backslash defeats the `listing.home` heuristic — but it touches the seam type and every backend; the browse client's `separatorOf` carries a TODO pointing at this alternative until a wire change is next scheduled.

 - **依赖调研（手写 vs 引入）。** Node 标准库本身就是维护中的跨平台 OS 层（`readdir(withFileTypes)`、`homedir`、路径语义）；调研过的替代品都过不了依赖门槛——文件管理器包（`node-file-manager`、`files-and-folders`、Syncfusion 的 provider）是整套 HTTP 应用（契合度不过），盘符工具（原生插件 `drivelist`、约七年未更的 `windows-drive-letters`）健康度／比例失当。browse 后端是标准库上的薄适配。

+- **路径编辑器的取消范围：对话框卡片。** browse 客户端的路径编辑器在按 Escape 与焦点离开卡片时取消，两者都在卡片范围的包装层而非输入框上监听——Tab 把焦点停到某个过滤命中的行之后，输入框已不在事件路径上，但 Escape 仍须收起编辑器（而非对话框），其后的焦点离开也仍须取消。不取消的豁免：窗口／标签页失焦、卡片内焦点移动，以及指针路径（编辑期间行与开关在 mousedown 时抑制焦点夺取）。预填与草稿末段过滤所用的分隔符从 `listing.home` 推断；下文的线上字段替代方案记录了被延期的权威形态。
 - **符号链接：为可进入性而跟随。** 用 `stat` 探测符号链接（断链／循环→跳过）；面包屑保留操作者导航的逻辑路径，`workspace.create` 在接纳时本就做 realpath 规范化。
 - **列举层级有上限，且流式处理。** 单次 `list` 至多返回 `maxEntries` 行（配置项，默认 1000——GitHub 网页端目录列举的同一上限）。层级经 `opendir` 流入一个按名排序、容量 `maxEntries + 1` 的候选窗口，内存保持 O(maxEntries)，可进入性探测只触及窗口内候选；线上 `DirectoryListing` 携带必填的 `truncated` 标志，让客户端明示不完整而不是静默缺尾。窗口内的断链符号链接不从窗口外回填——发生过驱逐本身已把层级标记为截断。窗口插入为二分查找、满窗尾部单次比较即拒绝（超大层级不能为每个 dirent 付出一次全窗扫描），且 `list(path, signal)` 透传载体的请求信号，滞塞网络目录的扫描不会在调用方断连后继续存活——扫描中的每个 await（打开、每次读取、每次符号链接探测）都与信号赛跑，中止路径放弃而非等待 close（Node 会把 close 排在在飞读取之后），被放弃的 settlement 全部吞掉，清理不会以未处理拒绝的形式冒出。无上限的层级对超大或恶意构造的目录就是内存／响应性漏洞。

 Behavior facts: listings return **directories only**, name-sorted, with symlinks-to-directories followed (broken/cyclic links skipped — the probe `stat` failing means "not enterable") and a host-owned `hidden` flag (POSIX dot convention) left for the client to act on; `crumbs` is the root-to-target ancestor chain, the root crumb labeled by its full path (`/`, `C:\`); an absent `list` path means the host account's home directory. `createDirectory` is non-recursive (a missing parent is a real failure, not a level to invent) and validates the name as a single non-blank segment even when called directly, mirroring the wire schema's fence. Both primitives reject an explicit path that is not fully qualified — relative forms, and on Windows the rooted drive-less forms (`\foo`, `/foo`) and incomplete UNC prefixes (`\\`, `\\server`) that `isAbsolute` accepts — with `directory-unreadable`/`directory-create-failed`, instead of letting `resolve` rebase it under the host process cwd or current drive. One `list` call returns at most `maxEntries` rows (config, default 1000 — the bound GitHub's web UI applies to directory listings), and the level streams through a bounded window so memory stays O(maxEntries) no matter how many children the directory holds: a cut level keeps the name-sorted head, counts hidden rows against the bound, probes only windowed candidates, and reports `truncated: true` so the client can say the level is incomplete (a windowed broken symlink is not backfilled from beyond the window — the eviction already marks the level truncated); window insertion is binary with an O(1) full-window tail rejection, and `list` threads the caller's `AbortSignal` so a disconnect or timeout stops the scan instead of letting it outlive the caller. Failures throw the seam's typed `DirectoryPickerError`. Policy rationale: [the directory-picker capability seam Agent Note](../../../.agents/notes/implemented/architecture/2026-07-28-directory-picker-capability-seam.md).

+- owner-scoped persistent `bash`
+- `str_replace_editor` with `view`, `create`, `str_replace`, and `insert`

+It composes the real local PTY, filesystem intent policy, and session sandbox policy. The keyless behavior snapshot drives the shipped JSON-RPC runtime through both tools and proves that shell cwd/environment survive across calls:

@@ -19,7 +19,7 @@ Placement and policy rulings folded into this decision:
 - **Not the `ctx.fs` seam.** `packages/fs/` is the model/session-facing storage stack (policy events, sandbox-swappable backends). Riding it would couple GUI browsing to the model's confinement backend — swapping `fs-sandbox` for the model must never change GUI behavior — and OS facts (home anchoring, hidden conventions) are not storage primitives. The picker seam stays presentation-free and model-free; `packages/host/` is its consumer-domain home.
 - **Dependency survey (hand-roll vs adopt).** Node's stdlib *is* the maintained cross-platform OS layer (`readdir(withFileTypes)`, `homedir`, path semantics); surveyed alternatives fail the dependency bar — file-manager packages (`node-file-manager`, `files-and-folders`, Syncfusion's provider) are whole HTTP apps (fit), drive-letter helpers (`drivelist` native addon, `windows-drive-letters` ~7y stale) fail health/proportionality. The browse backend is a thin adapter over stdlib.
 - **Hidden entries: return-and-flag.** The host stamps `hidden` (POSIX dot convention) and returns everything; the client filters. Display policy stays client-side, and the show-hidden toggle shipped as exactly that client-only change: a fixed-label footer toggle whose state lives in the pressed presentation (`aria-pressed` + check glyph), a dot-led path-draft prefix reveals the hidden entries it names, and the current selection is exempt from both the hidden and the prefix filter (it anchors the two-pane view). Windows' `FILE_ATTRIBUTE_HIDDEN` is not exposed by dirents — documented limitation until a native probe pays for itself.
-- **Path-editor cancel scope: the dialog card.** The browse client's path editor cancels on Escape and on focus leaving the card, both observed at a card-scope wrapper rather than the input — after Tab parks focus on a filtered row the input is off the event path, yet Escape must collapse the editor (not the dialog) and a later focus departure must still cancel. Non-cancel exemptions: window/tab focus loss, in-card focus moves, and pointer paths (rows and the toggle suppress focus steal on mousedown while editing). Separators for seeding and draft-tail filtering are inferred from `listing.home`; the wire-field alternative below records the deferred authoritative form.

Separators for seeding and draft-tail filtering are inferred from `listing.home`; the wire-field alternative below records the deferred authoritative form. Combobox semantics between the editor and the list it filters (`aria-expanded`/`aria-controls`/active-descendant, result announcements) are likewise deferred — today they read to assistive tech as separate widgets.
 - **Symlinks: follow for enterability.** `stat` probes symlinks (broken/cyclic → skipped); crumbs keep the logical path the operator navigated, and `workspace.create` already canonicalizes via realpath at adoption.
 - **Listing levels are bounded, and streamed.** One `list` call returns at most `maxEntries` rows (config, default 1000 — GitHub's web-UI directory-listing bound). The level streams via `opendir` into a name-sorted window of `maxEntries + 1` candidates, so memory stays O(maxEntries) and enterability probing touches only windowed candidates; the wire `DirectoryListing` carries a required `truncated` flag so the client states incompleteness instead of silently missing tail entries. A windowed broken symlink is not backfilled from beyond the window — the eviction already marks the level truncated. Window insertion is binary with an O(1) full-window tail rejection (an oversized level must not pay a window scan per dirent), and `list(path, signal)` threads the carrier's request signal so a scan of a stalled network directory cannot outlive a disconnected caller — every await in the scan (open, each read, each symlink probe) races the signal, an aborted exit abandons rather than awaits the close (Node queues close behind in-flight reads), and abandoned settlements are swallowed so cleanup can never surface as an unhandled rejection. An unbounded level is a memory/responsiveness hole for large or adversarial directories.
 - **Whole-filesystem scope, no roots config.** `workspace.create` accepts arbitrary paths and the API serves bash-driving methods, so a browse root would be UX scoping, not a boundary; configurability without a consumer fails the evidence bar. Deferred until a deployment needs it.

@@ -19,7 +19,7 @@ web GUI 的"打开本地文件夹"流程被焊死在一种交互上：`host.pick
 - **不用 `ctx.fs` seam。** `packages/fs/` 是面向模型／会话的存储栈（policy 事件、sandbox 可换后端）。骑上去会把 GUI 浏览耦合进模型的限制后端——为模型换 `fs-sandbox` 绝不能改变 GUI 行为——而 OS 事实（home 锚定、隐藏约定）也不是存储原语。picker seam 保持无展示、无模型；`packages/host/` 是它消费方域的家。
 - **依赖调研（手写 vs 引入）。** Node 标准库本身就是维护中的跨平台 OS 层（`readdir(withFileTypes)`、`homedir`、路径语义）；调研过的替代品都过不了依赖门槛——文件管理器包（`node-file-manager`、`files-and-folders`、Syncfusion 的 provider）是整套 HTTP 应用（契合度不过），盘符工具（原生插件 `drivelist`、约七年未更的 `windows-drive-letters`）健康度／比例失当。browse 后端是标准库上的薄适配。
 - **隐藏条目：返回并打标。** 宿主标注 `hidden`（POSIX 点前缀约定）并返回全部条目；客户端过滤。展示策略留在客户端，"显示隐藏"开关正是作为这一纯客户端改动落地：标签固定的 footer 开关，其状态由按下态呈现承载（`aria-pressed` + 勾选符号）；以点开头的路径草稿前缀会显出它所指名的隐藏条目；当前选中项则不受隐藏与前缀两种过滤影响（它锚定着双栏视图）。Windows 的 `FILE_ATTRIBUTE_HIDDEN` 不被 dirent 暴露——记为限制，直到原生探测值回其成本。
-- **路径编辑器的取消范围：对话框卡片。** browse 客户端的路径编辑器在按 Escape 与焦点离开卡片时取消，两者都在卡片范围的包装层而非输入框上监听——Tab 把焦点停到某个过滤命中的行之后，输入框已不在事件路径上，但 Escape 仍须收起编辑器（而非对话框），其后的焦点离开也仍须取消。不取消的豁免：窗口／标签页失焦、卡片内焦点移动，以及指针路径（编辑期间行与开关在 mousedown 时抑制焦点夺取）。预填与草稿末段过滤所用的分隔符从 `listing.home` 推断；下文的线上字段替代方案记录了被延期的权威形态。

 - **符号链接：为可进入性而跟随。** 用 `stat` 探测符号链接（断链／循环→跳过）；面包屑保留操作者导航的逻辑路径，`workspace.create` 在接纳时本就做 realpath 规范化。
 - **列举层级有上限，且流式处理。** 单次 `list` 至多返回 `maxEntries` 行（配置项，默认 1000——GitHub 网页端目录列举的同一上限）。层级经 `opendir` 流入一个按名排序、容量 `maxEntries + 1` 的候选窗口，内存保持 O(maxEntries)，可进入性探测只触及窗口内候选；线上 `DirectoryListing` 携带必填的 `truncated` 标志，让客户端明示不完整而不是静默缺尾。窗口内的断链符号链接不从窗口外回填——发生过驱逐本身已把层级标记为截断。窗口插入为二分查找、满窗尾部单次比较即拒绝（超大层级不能为每个 dirent 付出一次全窗扫描），且 `list(path, signal)` 透传载体的请求信号，滞塞网络目录的扫描不会在调用方断连后继续存活——扫描中的每个 await（打开、每次读取、每次符号链接探测）都与信号赛跑，中止路径放弃而非等待 close（Node 会把 close 排在在飞读取之后），被放弃的 settlement 全部吞掉，清理不会以未处理拒绝的形式冒出。无上限的层级对超大或恶意构造的目录就是内存／响应性漏洞。
 - **全盘可浏览，不做 roots 配置。** `workspace.create` 接受任意路径且 API 本就提供驱动 bash 的方法，浏览根只会是 UX 范围而非边界；没有消费方的可配置性过不了证据门槛。等到有部署需要再做。

@@ -20,6 +20,7 @@ Placement and policy rulings folded into this decision:
 - **Dependency survey (hand-roll vs adopt).** Node's stdlib *is* the maintained cross-platform OS layer (`readdir(withFileTypes)`, `homedir`, path semantics); surveyed alternatives fail the dependency bar — file-manager packages (`node-file-manager`, `files-and-folders`, Syncfusion's provider) are whole HTTP apps (fit), drive-letter helpers (`drivelist` native addon, `windows-drive-letters` ~7y stale) fail health/proportionality. The browse backend is a thin adapter over stdlib.
 - **Hidden entries: return-and-flag.** The host stamps `hidden` (POSIX dot convention) and returns everything; the client filters. Display policy stays client-side, and the show-hidden toggle shipped as exactly that client-only change: a fixed-label footer toggle whose state lives in the pressed presentation (`aria-pressed` + check glyph), a dot-led path-draft prefix reveals the hidden entries it names, and the current selection is exempt from both the hidden and the prefix filter (it anchors the two-pane view). Windows' `FILE_ATTRIBUTE_HIDDEN` is not exposed by dirents — documented limitation until a native probe pays for itself.
 - **Path-editor cancel scope: the dialog card.** The browse client's path editor cancels on Escape and on focus leaving the card, both observed at a card-scope wrapper rather than the input — after Tab parks focus on a filtered row the input is off the event path, yet Escape must collapse the editor (not the dialog) and a later focus departure must still cancel. Non-cancel exemptions: window/tab focus loss, in-card focus moves, and pointer paths (rows and the toggle suppress focus steal on mousedown while editing). Separators for seeding and draft-tail filtering are inferred from `listing.home`; the wire-field alternative below records the deferred authoritative form. Combobox semantics between the editor and the list it filters (`aria-expanded`/`aria-controls`/active-descendant, result announcements) are likewise deferred — today they read to assistive tech as separate widgets.
+- **Navigation lands selection-anchored.** Away from the display root, the browse client's navigate (a crumb jump or a submitted path) lists the target's parent level with the target selected and its children on the right — two panes throughout, so a crumb jump reads as stepping back one pane rather than collapsing to a single column. The display root (home, or a rootward chain with no parent crumb) keeps the single wide level; the parent leg runs under the same supersession scope as the landing, and its failure falls back to the single-pane landing quietly — the target listed fine, and nobody asked to see the parent.
 - **Symlinks: follow for enterability.** `stat` probes symlinks (broken/cyclic → skipped); crumbs keep the logical path the operator navigated, and `workspace.create` already canonicalizes via realpath at adoption.
 - **Listing levels are bounded, and streamed.** One `list` call returns at most `maxEntries` rows (config, default 1000 — GitHub's web-UI directory-listing bound). The level streams via `opendir` into a name-sorted window of `maxEntries + 1` candidates, so memory stays O(maxEntries) and enterability probing touches only windowed candidates; the wire `DirectoryListing` carries a required `truncated` flag so the client states incompleteness instead of silently missing tail entries. A windowed broken symlink is not backfilled from beyond the window — the eviction already marks the level truncated. Window insertion is binary with an O(1) full-window tail rejection (an oversized level must not pay a window scan per dirent), and `list(path, signal)` threads the carrier's request signal so a scan of a stalled network directory cannot outlive a disconnected caller — every await in the scan (open, each read, each symlink probe) races the signal, an aborted exit abandons rather than awaits the close (Node queues close behind in-flight reads), and abandoned settlements are swallowed so cleanup can never surface as an unhandled rejection. An unbounded level is a memory/responsiveness hole for large or adversarial directories.
 - **Whole-filesystem scope, no roots config.** `workspace.create` accepts arbitrary paths and the API serves bash-driving methods, so a browse root would be UX scoping, not a boundary; configurability without a consumer fails the evidence bar. Deferred until a deployment needs it.

 - **依赖调研（手写 vs 引入）。** Node 标准库本身就是维护中的跨平台 OS 层（`readdir(withFileTypes)`、`homedir`、路径语义）；调研过的替代品都过不了依赖门槛——文件管理器包（`node-file-manager`、`files-and-folders`、Syncfusion 的 provider）是整套 HTTP 应用（契合度不过），盘符工具（原生插件 `drivelist`、约七年未更的 `windows-drive-letters`）健康度／比例失当。browse 后端是标准库上的薄适配。
 - **隐藏条目：返回并打标。** 宿主标注 `hidden`（POSIX 点前缀约定）并返回全部条目；客户端过滤。展示策略留在客户端，"显示隐藏"开关正是作为这一纯客户端改动落地：标签固定的 footer 开关，其状态由按下态呈现承载（`aria-pressed` + 勾选符号）；以点开头的路径草稿前缀会显出它所指名的隐藏条目；当前选中项则不受隐藏与前缀两种过滤影响（它锚定着双栏视图）。Windows 的 `FILE_ATTRIBUTE_HIDDEN` 不被 dirent 暴露——记为限制，直到原生探测值回其成本。
 - **路径编辑器的取消范围：对话框卡片。** browse 客户端的路径编辑器在按 Escape 与焦点离开卡片时取消，两者都在卡片范围的包装层而非输入框上监听——Tab 把焦点停到某个过滤命中的行之后，输入框已不在事件路径上，但 Escape 仍须收起编辑器（而非对话框），其后的焦点离开也仍须取消。不取消的豁免：窗口／标签页失焦、卡片内焦点移动，以及指针路径（编辑期间行与开关在 mousedown 时抑制焦点夺取）。预填与草稿末段过滤所用的分隔符从 `listing.home` 推断；下文的线上字段替代方案记录了被延期的权威形态。编辑器与其过滤的列表之间的 combobox 语义（`aria-expanded`／`aria-controls`／active-descendant、结果播报）同样被延期——目前二者在辅助技术看来是彼此独立的控件。
+- **导航以选中项为锚落地。** 在展示根之外，browse 客户端的导航（crumb 跳转或提交的路径）列出目标的父层级，选中目标并在右侧展示其子项——全程双栏，因此 crumb 跳转读作后退一栏，而不是塌缩成单列。展示根（home，或没有父 crumb 的抵根链）保持单个宽层级；父层级这一程与落地共用同一 supersession 范围，其失败会静默回退到单栏落地——目标本身列举无误，本也没有人要求查看父层级。
 - **符号链接：为可进入性而跟随。** 用 `stat` 探测符号链接（断链／循环→跳过）；面包屑保留操作者导航的逻辑路径，`workspace.create` 在接纳时本就做 realpath 规范化。
 - **列举层级有上限，且流式处理。** 单次 `list` 至多返回 `maxEntries` 行（配置项，默认 1000——GitHub 网页端目录列举的同一上限）。层级经 `opendir` 流入一个按名排序、容量 `maxEntries + 1` 的候选窗口，内存保持 O(maxEntries)，可进入性探测只触及窗口内候选；线上 `DirectoryListing` 携带必填的 `truncated` 标志，让客户端明示不完整而不是静默缺尾。窗口内的断链符号链接不从窗口外回填——发生过驱逐本身已把层级标记为截断。窗口插入为二分查找、满窗尾部单次比较即拒绝（超大层级不能为每个 dirent 付出一次全窗扫描），且 `list(path, signal)` 透传载体的请求信号，滞塞网络目录的扫描不会在调用方断连后继续存活——扫描中的每个 await（打开、每次读取、每次符号链接探测）都与信号赛跑，中止路径放弃而非等待 close（Node 会把 close 排在在飞读取之后），被放弃的 settlement 全部吞掉，清理不会以未处理拒绝的形式冒出。无上限的层级对超大或恶意构造的目录就是内存／响应性漏洞。
 - **全盘可浏览，不做 roots 配置。** `workspace.create` 接受任意路径且 API 本就提供驱动 bash 的方法，浏览根只会是 UX 范围而非边界；没有消费方的可配置性过不了证据门槛。等到有部署需要再做。

 Behavior facts: listings return **directories only**, name-sorted, with symlinks-to-directories followed (broken/cyclic links skipped — the probe `stat` failing means "not enterable") and a host-owned `hidden` flag (POSIX dot convention) left for the client to act on; `crumbs` is the root-to-target ancestor chain, the root crumb labeled by its full path (`/`, `C:\`); an absent `list` path means the host account's home directory. `createDirectory` is non-recursive (a missing parent is a real failure, not a level to invent) and validates the name as a single non-blank segment even when called directly, mirroring the wire schema's fence. Both primitives reject an explicit path that is not fully qualified — relative forms, and on Windows the rooted drive-less forms (`\foo`, `/foo`) and incomplete UNC prefixes (`\\`, `\\server`) that `isAbsolute` accepts — with `directory-unreadable`/`directory-create-failed`, instead of letting `resolve` rebase it under the host process cwd or current drive. One `list` call returns at most `maxEntries` rows (config, default 1000 — the bound GitHub's web UI applies to directory listings), and the level streams through a bounded window so memory stays O(maxEntries) no matter how many children the directory holds: a cut level keeps the name-sorted head, counts hidden rows against the bound, probes only windowed candidates, and reports `truncated: true` so the client can say the level is incomplete (a windowed broken symlink is not backfilled from beyond the window — the eviction already marks the level truncated); window insertion is binary with an O(1) full-window tail rejection, and `list` threads the caller's `AbortSignal` so a disconnect or timeout stops the scan instead of letting it outlive the caller. Failures throw the seam's typed `DirectoryPickerError`. Policy rationale: [the directory-picker capability seam Agent Note](../../../.agents/notes/implemented/architecture/2026-07-28-directory-picker-capability-seam.md).

Every surface that persists or lists sessions resolves one directory under
the Harness home, so history is shared across working directories instead
of scattered per project.

 `expandHomePath()` expands `~`, `~/...`, and Windows-style `~\...` prefixes against the operating-system home directory. It leaves non-tilde paths and `~user/...` untouched.
 
+## Session store

+`resolveSessionsRoot()` resolves the shared session-store root under the Harness home, by the same precedence as `resolveDshHome()`. `SESSIONS_DIR_NAME` owns its directory name: `sessions`. Every surface that persists sessions resolves this one directory, so history is shared across working directories instead of scattered per project; a persistence backend may still partition inside it. Two surfaces resolving different roots would silently split one user's history into disjoint stores, which is why the location is owned here rather than joined per caller.

+# Agent Note: Launcher-owned session identity and exit line
+
+Status: implemented
+
+English | [中文](2026-07-28-launcher-owned-resume-identity.zh.md)
+
+## Problem
+
+Two facts a launcher owns were shipped as deployment config keys on `dsh-tui-demo`: `resumeSessionId` (which session `main` binds to) and `resumeCommand` (the exit hint template, with `{session}` interpolated). Neither varies by deployment — both are properties of how the process was invoked, which only the launcher knows.
+
+Routing them through YAML made them silently droppable. `@cordisjs/plugin-include` applies a targeted patch by replacing whole top-level keys (`target[key] = value`), so a personal `~/.dsh/config.yaml` patching the `tui-agent` entry's `config` replaces the shipped block entirely. A user overlay written to change provider and model therefore deleted every resume key it did not restate, and nothing reported it: absent `resumeCommand` legitimately means "no fallback configured".
+
+Both failures were live in one real overlay. The exit hint stopped printing, because the overlay omitted `resumeCommand`. Worse, the overlay carried `resumeSessionId: !!js process.env.RESUME_SESSION_ID` — a stale line from before [the env-var bridge was removed](../../archived/architecture/2026-07-24-dsh-commander-argument-adapter.md) — which overwrote the shipped `!!js "typeof resumeSessionId === 'string' ? …"` intake with a read of a variable nothing sets. `dsh --resume <valid-id>` then started a *fresh* session and said nothing, reproduced directly: the banner showed a newly minted id, not the requested one. The [`dsh meta`](../feature/2026-07-28-dsh-meta-source-workspace.md) note had recorded this silent resume as an unexplained pre-existing defect; the overlay's shallow replacement is the cause.
+
+A config key cannot express these facts safely, because the deployment is not the authority on them.
+
+## Decision
+
+Session identity and the exit line are launcher-owned context slots, provided before any Loader entry mounts. Neither appears in any `cordis.yml` or in `dsh-tui`'s or `dsh-tui-demo`'s `Config`.
+
+`dsh-tui` declares both slots beside the existing `tuiResumeHost` host capability, which set the precedent — a resume host has always been a provided capability rather than config:
+
+- `MAIN_SESSION_ID_KEY` carries a `MainSessionIdentity` (`{ id: SessionId, resume: boolean }`). `dsh-tui-demo` binds both the TUI and the configured agent to `id`, and takes the history-loading `resumeSessionId` path only when `resume` is set, because that path requires an existing log and fails loud without one. An absent slot means no launcher chose a session, so the app mints `main-session-<uuid>` and creates it fresh.
+- `TUI_GOODBYE_MESSAGE_KEY` carries the complete line printed once the terminal is released on exit. Absent prints nothing.
+
+`apps/cli` mints or selects the id and builds the line from the invocation it is reproducing, sharing one `resumeArgs` helper with the `/resume` execve handoff so the printed command and the in-place handoff cannot diverge. The line now names `--config` when one was passed, and reproduces `dsh meta --resume <id>` in meta mode — closing the mode-aware hint deferred by the `dsh meta` note, where a copied hint previously only worked from the checkout.
+
+**`ctx.provide` is the only channel from launcher argv into a Loader-mounted plugin.** Config `!!js` expressions evaluate as `with (entry.ctx) { eval(expr) }` (`vendor/loader/src/config/utils.ts`), so a bare identifier resolves against the entry's context and nothing else reaches it. The slot therefore cannot be removed while the app bundle is mounted from YAML; what changes is that it is now internal launcher↔app plumbing instead of a documented key a config author must wire correctly.
+
+The message is a plain string, not a callback. That forces the launcher to know the id before boot, which is why minting moved out of the app bundle — and it keeps exit free of awaited work after the terminal is released.
+
+The TUI owns rendering, not wording: it applies `displayText` before its own `palette.muted`, so a hostile `--config` path cannot inject terminal escapes into the exit line. Sanitizing means the launcher cannot embed its own ANSI.
+
+## Alternatives considered
+
+**Keep the keys and add built-in defaults in `dsh-tui-demo`.** Rejected: a default in code survives an overlay, but two ways to state one fact remain, and a config author can still set the key wrong — which is exactly how the stale `process.env.RESUME_SESSION_ID` line disabled resume.
+
+**Merge `dsh-tui-demo` into `apps/cli` and delete the slot entirely.** Rejected after investigation, though it is the only way to remove the slot. `examples/tui-agent/code-mode.cordis.yml` patches the `tui-agent` entry through a nested `plugin-include` to switch `tools.mode` and the persona, and `examples/cordis-agent/cordis.yml` reuses the bundle as a different product; both extension points exist only because `tui-agent` is a declared config entry. Merging also moves a 162-line, 18-dependency composition into the CLI's `v8 ignore` process-wiring block, out of the per-file coverage gate.
+
+**Put the goodbye message on `TuiResumeHost`.** Rejected: an exit line is not a handoff capability, and a host that cannot replace its process may still want to print one. They are independent slots.
+
+**Have the host supply only the command text and let the TUI keep the `To resume this session:` prefix.** Rejected: the TUI would retain resume vocabulary for a string it no longer understands, and meta mode proves the launcher is the only component that knows what the command should say.
+
+**Let the TUI keep suppressing the line until the session is durably persisted.** Rejected: that check is why the exit path queried persistence and swallowed listing failures. A plain string cannot consult persistence, and misuse now fails loud through `agent-loop/config-start-failed` rather than silently resuming nothing.
+
+**A callback (`goodbyeMessage(agent)`) so the host could decide at exit time.** Rejected: it restores async work after `ui.stop()`, reintroducing a hang risk during teardown for a string that is already knowable at boot.
+
+## Consequences
+
+- Removing two published `Config` keys is a breaking config change: a stale config naming either now fails schema validation at boot instead of degrading silently. Intended, and acceptable pre-release.
+- `TuiResumeHost` is unchanged, but `TuiRuntime` gains `goodbyeMessage`; `apps/cli` is the only provider.
+- The exit line prints even for a session with no log (launch, quit immediately). Using it then fails loud rather than starting a surprise session. This is the deliberate cost of dropping the persistence check.
+- `dsh-tui` no longer reads `sessionPersistence` at all: `currentResumeCommand`, `listWorkspaceSessions`, and its swallowed-error path are deleted, and the `/resume` selector's `sessionQuery` reads are now the only session discovery in the TUI.
+- The launcher mints session ids for its own app, so a non-CLI host that provides no slot keeps the bundle's own minting.
+
+## Testing
+
+`packages/ui/tui/tests/tui.spec.ts` pins the printed line, the absent-slot silence, and escape sanitization of a hostile message; the former two exit-suppression tests are replaced, since suppression is the behavior this change removes. `packages/examples/tui-demo/tests/tui-agent.spec.ts` drives the identity slot for the resume, launcher-minted, and no-slot cases through a fake `ctx.get`.
+
+The load-bearing coverage is `examples/tui-agent/tests/tui-keyless-smoke.e2e.ts`, which launches the real `apps/cli/src/bin.ts` in a PTY: one test asserts the exit line carries `--config`, and a regression test seeds a personal `config.yaml` that replaces the entire `tui-agent` config block and asserts the line still prints — encoding "an overlay cannot drop resume" as an executed contract rather than a comment.
+
+Verified live in tmux against the real personal overlay: the defect reproduced on unmodified staging (requested id ignored, fresh id in the banner), and on this branch the same overlay yields a printed exit line, a `--resume` that restores the prior turn, and a `/resume` selector marking the session `current · live · persisted`. A wrong id now fails loud.

+# Agent Note：由启动器持有的会话身份与退出行
+
+Status: implemented
+
+[English](2026-07-28-launcher-owned-resume-identity.md) | 中文
+
+## Problem
+
+有两项本应由启动器持有的事实，却被作为 `dsh-tui-demo` 上的部署配置键交付：`resumeSessionId`（`main` 绑定到哪个会话）与 `resumeCommand`（退出提示的模板，其中 `{session}` 会被插值）。二者都不随部署而变——它们都是进程被如何调用的属性，而这一点只有启动器知道。
+
+把它们经由 YAML 传递，使其可被静默丢弃。`@cordisjs/plugin-include` 施加定向补丁的方式是替换整个顶层键（`target[key] = value`），因此一份对 `tui-agent` 条目的 `config` 打补丁的个人 `~/.dsh/config.yaml`，会把交付时的整块内容整体替换掉。于是，一份为改动 provider 和 model 而写的用户 overlay，会删掉它未重述的每一个 resume 键，且没有任何东西报告这一点：缺失 `resumeCommand` 合法地意味着「未配置回退」。
+
+两处失效在同一份真实的 overlay 中同时存在。退出提示不再打印，因为该 overlay 省略了 `resumeCommand`。更糟的是，该 overlay 带着 `resumeSessionId: !!js process.env.RESUME_SESSION_ID`——一行来自 [env 变量桥被移除](../../archived/architecture/2026-07-24-dsh-commander-argument-adapter.md)之前的陈旧代码——它用一次对某个无人设置的变量的读取，覆盖掉了交付时的 `!!js "typeof resumeSessionId === 'string' ? …"` 入口。此后 `dsh --resume <valid-id>` 会开启一个*全新*会话且什么都不说，并被直接复现：banner 显示的是一个新铸造的 id，而非所请求的那个。[`dsh meta`](../feature/2026-07-28-dsh-meta-source-workspace.md) note 曾把这次静默的 resume 记为一处无法解释的既有缺陷；而 overlay 的浅层替换正是其成因。
+
+一个配置键无法安全地表达这些事实，因为部署方并非它们的权威。
+
+## Decision
+
+会话身份与退出行是由启动器持有的上下文槽位，在任何 Loader 条目挂载之前提供。二者都不出现在任何 `cordis.yml` 中，也不出现在 `dsh-tui` 或 `dsh-tui-demo` 的 `Config` 中。
+
+`dsh-tui` 在既有的 `tuiResumeHost` 宿主能力旁声明这两个槽位，后者确立了先例——resume 宿主一直是一项被提供的能力，而非配置：
+
+- `MAIN_SESSION_ID_KEY` 承载一个 `MainSessionIdentity`（`{ id: SessionId, resume: boolean }`）。`dsh-tui-demo` 把 TUI 与所配置的 agent 都绑定到 `id`，并且仅当 `resume` 被置位时才走加载历史的 `resumeSessionId` 路径，因为该路径要求存在一份日志、否则会明确报错。槽位缺失意味着没有启动器选定会话，于是应用铸造 `main-session-<uuid>` 并新建它。
+- `TUI_GOODBYE_MESSAGE_KEY` 承载退出时终端释放后打印一次的完整行。缺失则什么都不打印。
+
+`apps/cli` 铸造或选定 id，并依据它所复现的那次调用构建该行，与 `/resume` 的 execve 移交共用同一个 `resumeArgs` 助手，从而使打印出的命令与原地移交不会分歧。该行现在会在传入了 `--config` 时命名它，并在 meta 模式下复现 `dsh meta --resume <id>`——从而收口了 `dsh meta` note 所推迟的随 mode 变化的提示，在那里被复制的提示此前只有在检出目录中才有效。
+
+**`ctx.provide` 是从启动器 argv 进入被 Loader 挂载的插件的唯一通道。** 配置的 `!!js` 表达式会以 `with (entry.ctx) { eval(expr) }`（`vendor/loader/src/config/utils.ts`）求值，因此一个裸标识符会针对该条目的上下文解析，别无它物可达。于是只要应用 bundle 仍从 YAML 挂载，这个槽位就无法被移除；变化之处在于它现在是启动器↔应用之间的内部管线，而不再是一个配置作者必须正确接线的、有文档记载的键。
+
+该消息是一个纯字符串，而非回调。这迫使启动器在启动前就知道 id，也正是铸造从应用 bundle 中移出的原因——并且它让退出在终端释放之后免于任何被 await 的工作。
+
+TUI 持有渲染，而非措辞：它在自己的 `palette.muted` 之前先应用 `displayText`，因此一个恶意的 `--config` 路径无法把终端转义序列注入退出行。做净化意味着启动器无法嵌入自己的 ANSI。
+
+## Alternatives considered
+
+**保留这些键，并在 `dsh-tui-demo` 中加入内建默认值。** 拒绝：代码中的默认值能在 overlay 下存活，但表达同一事实的两种途径依然并存，而配置作者仍可把键设错——这正是那行陈旧的 `process.env.RESUME_SESSION_ID` 使 resume 失效的方式。
+
+**把 `dsh-tui-demo` 合并进 `apps/cli` 并彻底删除该槽位。** 经调查后拒绝，尽管这是移除该槽位的唯一途径。`examples/tui-agent/code-mode.cordis.yml` 通过一个嵌套的 `plugin-include` 给 `tui-agent` 条目打补丁，以切换 `tools.mode` 与人设，而 `examples/cordis-agent/cordis.yml` 把该 bundle 作为另一款产品复用；这两个扩展点都仅因 `tui-agent` 是一个声明式配置条目才存在。合并还会把一段 162 行、18 个依赖的组合逻辑挪进 CLI 的 `v8 ignore` 进程接线块中，脱离逐文件覆盖率门禁。
+
+**把 goodbye 消息放到 `TuiResumeHost` 上。** 拒绝：退出行不是一项移交能力，而一个无法替换自身进程的宿主仍可能想要打印一行。它们是相互独立的槽位。
+
+**让宿主只提供命令文本，而由 TUI 保留 `To resume this session:` 前缀。** 拒绝：TUI 将为一个它已不再理解的字符串保留 resume 词汇，而 meta 模式证明启动器才是唯一知道该命令应当说什么的组件。
+
+**让 TUI 继续在会话被持久化之前抑制该行。** 拒绝：这项检查正是退出路径要查询持久化并吞掉列举失败的原因。一个纯字符串无法查询持久化，而误用现在会经由 `agent-loop/config-start-failed` 明确报错，而不是静默地恢复了个空。
+
+**用一个回调（`goodbyeMessage(agent)`）让宿主能在退出时决定。** 拒绝：它会在 `ui.stop()` 之后恢复异步工作，为一个在启动时就已可知的字符串，重新引入拆解期间的挂起风险。
+
+## Consequences
+
+- 移除两个已发布的 `Config` 键是一次破坏性配置变更：一份命名了任一键的陈旧配置，现在会在启动时的 schema 校验中明确报错，而不再静默降级。这是有意为之，且在预发布阶段可以接受。
+- `TuiResumeHost` 保持不变，但 `TuiRuntime` 新增 `goodbyeMessage`；`apps/cli` 是唯一的提供方。
+- 即便某会话没有日志（启动后立即退出），退出行也会打印。此时使用它会明确报错，而不是开启一个意外的会话。这是丢弃持久化检查的有意代价。
+- `dsh-tui` 完全不再读取 `sessionPersistence`：`currentResumeCommand`、`listWorkspaceSessions` 及其吞错路径都被删除，`/resume` 选择器的 `sessionQuery` 读取如今是 TUI 中唯一的会话发现途径。
+- 启动器为其自身的应用铸造会话 id，因此一个不提供任何槽位的非 CLI 宿主，仍保留 bundle 自带的铸造逻辑。
+
+## Testing
+
+`packages/ui/tui/tests/tui.spec.ts` 钉住打印出的行、槽位缺失时的静默，以及对恶意消息的转义净化；此前那两个退出抑制测试被替换，因为抑制正是本次改动移除的行为。`packages/examples/tui-demo/tests/tui-agent.spec.ts` 通过一个伪造的 `ctx.get`，为 resume、启动器铸造与无槽位三种情形驱动身份槽位。
+
+承重的覆盖是 `examples/tui-agent/tests/tui-keyless-smoke.e2e.ts`，它在一个 PTY 中拉起真实的 `apps/cli/src/bin.ts`：一个测试断言退出行携带 `--config`，一个回归测试植入一份个人 `config.yaml` 来替换整块 `tui-agent` 配置块并断言该行仍会打印——把「overlay 不能丢掉 resume」编码为一条被执行的契约，而非一句注释。
+
+在 tmux 中针对真实的个人 overlay 做过实测：该缺陷在未修改的 staging 上复现（所请求的 id 被忽略，banner 里是新的 id），而在本分支上同一份 overlay 会产出一行打印的退出行、一个能恢复上一轮次的 `--resume`，以及一个把该会话标记为 `current · live · persisted` 的 `/resume` 选择器。错误的 id 现在会明确报错。

 Editor input calls `agent.send()` while idle and `agent.steer()` while a turn is running. Cancellation, reasoning visibility, tool-card expansion, redraw, transcript clearing, and exit are terminal-only controls. `/exit` and `/quit` share the same exit path: they cancel an active turn, wait for idle, and then restore and close the terminal. The idle footer derives context occupancy from `tokenMeter` and shows the selected model and explicit reasoning effort; during a run, elapsed activity and the Escape interrupt hint replace that summary. `/status` remains available in either state and appends a detailed terminal-only snapshot: session identity and timestamps, selected model, reasoning effort/default state and reasoning visibility, lifecycle counts folded from the event log, the same deduplicated usage buckets and KV-cache rate as the footer, and context use from `tokenMeter` plus the selected model's advertised capacity. The plugin registers the shared `userInteraction` provider and presents queued questions in a wide bottom-left keyboard panel with batch progress, numbered options, and aligned descriptions; the panel's controls hint lists only actions meaningful for the current option count, omitting navigation when exactly one option is shown; agent behavior and answer logging remain owned by their existing services.

+# Agent Note: tmux-location context
+
+Status: implemented
+

+
+## Problem
+
+An agent running inside tmux has no way to tell the model where it is: which session, window, and pane the process occupies, and how the window is laid out. A user directing several panes wants the model to orient itself to its own location so instructions like "the pane below" or "this window" resolve. The location must reach the model as durable, reconstructable context, not a system-prompt value rewritten in place, and must cost nothing when the location has not changed.
+
+tmux exposes this without a daemon: `$TMUX_PANE` names the process's pane, and `tmux display-message -t "$TMUX_PANE" -p '<format>'` prints any pane/window/session field. The open question was how to observe it — pull on each preparation, or push from a tmux hook — and how to avoid a per-step token cost and hidden process-local state.
+
+## Decision
+
+`@deepseek-ai/dsh-tmux-context` is an opt-in function plugin in `packages/context/tmux-context/`, alongside the other bounded request-context enrichments that define neither a tool nor a service. Shipped examples do not mount it because tmux-location disclosure and its token cost are deployment policy.
+
+**Pull on the first step of each turn, not a tmux push.** The plugin prepends an `agent/step` listener and acts only when `step === 1`. A pull model needs no background process, no hook installation in the user's tmux, and no teardown; it re-reads current state each turn so a moved, renamed, or re-laid-out pane is picked up naturally. Gating on the first step makes the reading per-turn: a location is stable within a turn, and re-querying every step would add cost without new information. A pane moved mid-turn is reflected on the next turn, which is the accepted tradeoff for the simpler design.
+
+**Read through the `ctx.bash` seam, never raw `child_process`.** The listener runs the tmux/`ps` read commands through `ctx.bash`, so the deployment's sandbox and policy apply and the plugin owns no subprocess code. Absent `ctx.bash`, absent tmux env, a wrong field count, or an empty pane id each make the attempt a no-op, matching how `workspace-context` no-ops without an `fs` provider.
+
+**Detect a real pane by tty, not by `$TMUX_PANE` alone.** `$TMUX_PANE` is inherited: a terminal launched from a tmux shell (a VS Code integrated terminal, a desktop launcher) carries `$TMUX`/`$TMUX_PANE` from that ancestor even though the process does not live in that pane, which otherwise injects a stale, wrong location. The command resolves this process's controlling terminal with `ps -o tty= -p <pid>` (the agent's own pid, passed in-process) and compares it to the pane's `#{pane_tty}`; fields are emitted only on a match. A genuine pane owns this process's tty; an inherited environment names some other pane's tty and reads as "not in tmux". Checking `$TMUX` instead does not help — it is inherited identically. This is the definitive discriminator and needs no allowlist of terminal emulators.
+
+**Own location and layout only.** The queried fields are session name, window index/name, pane index/id, window/pane active flags, and `window_layout`. Pane and window pixel sizes are excluded (layout tree conveys structure; sizes are noisy and change on every terminal resize). Sibling-pane contents are never captured (`capture-pane`), keeping the reading small and avoiding scraping unrelated, possibly sensitive, output.
+
+**Inject only on change, with optional interval floor.** When due, the plugin calls `agent.inject()` for one `user/message` with source `{ kind: 'plugin', plugin: 'tmux-context' }`. Change suppression compares the rendered state block (everything after the turn preamble line) against the latest injection of this source, found by scanning raw durable session events — so the schedule survives compaction and process resume without a process-local cache. The optional `refreshIntervalMs` (manually validated as a non-negative safe integer at plugin load) additionally suppresses injections within that window of the latest one.
+
+### Text
+
+```text
+tmux location (turn <turn>):
+session <session>, window <index> "<name>", pane <index> <pane-id>
+window active=<0|1>, pane active=<0|1>, layout <window-layout>
+```
+
+The turn preamble is the volatile first line; the two-line state block below it is the unit compared for change suppression, so re-injection is driven by tmux state, not loop position.
+
+### Durability and request reconstruction
+
+Each reading is a normal surface node until compaction shadows it; the plugin contributes nothing to system-prompt assembly and `request/header` carries no tmux-context text. The reading records a preparation attempt, not a committed step: because the prepended listener runs first, its append may remain when a later `agent/step` listener cancels or fails the attempt, and the append-only log performs no rollback.
+
+The published `./invariant` companion registers no runtime check: a reading is a per-turn snapshot of external tmux state, so the session holds no cross-event relation to validate, and scheduling and format stay pinned by the package's pipeline tests.
+
+## Consequences
+
+An agent booted inside tmux now receives its own session/window/pane location and window layout as durable, source-attributed context, updated per turn when the location changes. Deployments opt in through cordis.yml; the default spine and shipped examples stay silent. Outside a real tmux pane — including a terminal that merely inherited `$TMUX`/`$TMUX_PANE` — or without a `ctx.bash` executor, the plugin is inert with no error, so composing it is safe everywhere. Because the reading is one durable `user/message`, it survives compaction as ordinary history, contributes nothing to system-prompt assembly or request headers, and costs at most one two-line message per changed turn. The pull model adds one bash execution (through the sandboxed bash seam) on the first step of each turn that is due — internally a `ps` tty probe, a `tmux display-message` tty query, and the field query. Only the optional interval floor suppresses the query itself; an unchanged location is known only after querying, so it suppresses the injection alone.
+
+## Testing
+
+Unit tests pin: first-step injection and source/surface metadata; the `$TMUX_PANE`-keyed command including its `#{pane_tty}`-vs-`ps -o tty=` guard; step-gating; change suppression across turns and re-injection on a moved pane; positive-interval suppression and threshold; every no-op path (no bash, nonzero exit, wrong field count, empty pane id, aborted signal); prepended ordering before ordinary `agent/step` listeners; resilience to a corrupt prior reading (non-text block, single-line text); and config rejection of negative and non-integer intervals. Per-file coverage is 100%.
+
+## Alternatives considered
+
+- **Push from a tmux hook / background watcher** — rejected: requires installing hooks in the user's tmux and a background process with teardown, to gain mid-step freshness that per-turn context does not need.
+- **Run every step** — rejected: location is stable within a turn; re-querying adds token cost without new information. Gating on `step === 1` yields per-turn readings.
+- **Raw `child_process`** — rejected: bypasses the sandbox/policy seam and hand-rolls subprocess code the `ctx.bash` executor already owns.
+- **Include pane/window pixel sizes** — rejected: sizes churn on every resize and add noise; the layout tree already conveys structure.
+- **Scrape sibling panes with `capture-pane`** — rejected: large, noisy, and privacy-sensitive; out of scope for "own location".
+- **Dynamic system-prompt section** — rejected: replacing a value erases the earlier readings behind prior reasoning and is not reconstructable; one durable attributed message records each location where it became visible.
+- **Trust `$TMUX_PANE` (or `$TMUX`) presence** — rejected: both are inherited by terminals launched from a tmux shell (VS Code integrated terminal), so a non-pane process injects a stale location. The pane `#{pane_tty}` vs. this process's controlling tty is the definitive check.
+- **Denylist known terminal emulators (e.g. `TERM_PROGRAM=vscode`)** — rejected: a partial, ever-growing list that still misses other launchers; the tty match is exact and launcher-agnostic.
+- **A runtime invariant validating each reading's turn, position, and format** — shipped initially, then removed: it re-derived the producer's own scheduling from the log and asserted a regex over text the same package had just rendered, so it restated `apply()` rather than checking an independent relation. Every failure it could report required an edit to this package, which its pipeline tests already catch. Reintroduce a companion check only for a relation the plugin does not itself compute — for example if readings gain cross-turn ordering or enclosure obligations that another package can violate.

+# Agent Note：tmux 位置上下文
+
+Status: implemented
+
+[English](2026-07-27-tmux-location-context.md) | 中文
+
+## 问题
+
+运行在 tmux 内的 agent 无法告诉模型自己身在何处：进程占据哪个 session、window、pane，以及 window 如何布局。当用户操作多个 pane 时，希望模型能对自身位置有所定位，从而让"下方的 pane""这个 window"之类的指令得以解析。位置必须以持久、可重建的上下文形式送达模型，而非在原地被改写的系统提示值，并且当位置未变化时不产生任何成本。
+
+tmux 无需守护进程即可暴露这些信息：`$TMUX_PANE` 标识进程所在 pane，`tmux display-message -t "$TMUX_PANE" -p '<format>'` 可打印任意 pane/window/session 字段。待决问题在于如何观测——在每次准备时拉取，还是由 tmux hook 推送——以及如何避免逐步骤 token 成本与隐藏的进程内状态。
+
+## 决策
+
+`@deepseek-ai/dsh-tmux-context` 是位于 `packages/context/tmux-context/` 的可选启用型函数插件，与其他既不定义工具也不定义服务的有界请求上下文增强并列。随附示例不挂载它，因为 tmux 位置披露及其 token 成本属于部署策略。
+
+**在每轮的第一个 step 拉取，而非 tmux 推送。** 插件前置注册一个 `agent/step` 监听器，仅在 `step === 1` 时动作。拉取模型无需后台进程、无需在用户的 tmux 中安装 hook、也无需清理；它每轮重新读取当前状态，因此被移动、改名或重新布局的 pane 都会被自然感知。以第一个 step 为门槛使读数按轮次生成：位置在一轮内是稳定的，逐步骤重复查询只会增加成本而不带来新信息。轮次中途移动的 pane 会在下一轮反映，这是换取更简单设计所接受的取舍。
+
+**通过 `ctx.bash` seam 读取，绝不用裸 `child_process`。** 监听器通过 `ctx.bash` 运行 tmux／`ps` 只读命令，从而应用部署方的沙箱与策略，插件不拥有任何子进程代码。`ctx.bash` 缺失、tmux 环境缺失、字段数不符或 pane id 为空，都会使本次尝试成为空操作，与 `workspace-context` 在无 `fs` provider 时的空操作一致。
+
+**以 tty 判定真实 pane，而非仅凭 `$TMUX_PANE`。** `$TMUX_PANE` 会被继承：从 tmux shell 启动的终端（VS Code 集成终端、桌面启动器）会从该祖先进程带上 `$TMUX`／`$TMUX_PANE`，即使进程并不位于那个 pane 中，否则就会注入一个陈旧且错误的位置。命令用 `ps -o tty= -p <pid>`（在进程内传入 agent 自身的 pid）解析本进程的控制终端，并与 pane 的 `#{pane_tty}` 比较；只有匹配时才输出字段。真正的 pane 拥有本进程的 tty；继承而来的环境指向的是另一个 pane 的 tty，因而被读作"不在 tmux 中"。改为检查 `$TMUX` 也无济于事——它同样会被继承。这是决定性的判别依据，且无需维护终端模拟器名单。
+
+**仅自身位置与布局。** 查询字段为 session name、window index/name、pane index/id、window/pane 活动标志以及 `window_layout`。省略 pane 与 window 像素尺寸（布局树已传达结构；尺寸嘈杂且每次终端缩放都会变化）。从不采集相邻 pane 内容（`capture-pane`），使读数保持小巧，并避免抓取无关、可能敏感的输出。
+
+**仅在变化时注入，并可选间隔下限。** 需要时，插件调用 `agent.inject()` 注入一条来源为 `{ kind: 'plugin', plugin: 'tmux-context' }` 的 `user/message`。变化抑制将渲染出的状态块（轮次前缀行之后的全部内容）与该来源的最近一次注入比较，后者通过扫描原始持久会话事件获得——因此调度可跨压缩与进程恢复存续，无需进程内缓存。可选的 `refreshIntervalMs`（在插件加载时手动校验为非负安全整数）会额外抑制距最近一次注入不足该窗口的注入。
+
+### 文本
+
+```text
+tmux location (turn <turn>):
+session <session>, window <index> "<name>", pane <index> <pane-id>
+window active=<0|1>, pane active=<0|1>, layout <window-layout>
+```
+
+轮次前缀是易变的首行；其下的两行状态块才是变化抑制所比较的单元，因此重新注入由 tmux 状态驱动，而非循环位置。
+
+### 持久性与请求重建
+
+每条读数在被压缩遮蔽前都是普通表层节点；插件对系统提示装配毫无贡献，`request/header` 也不携带任何 tmux-context 文本。读数记录的是一次准备尝试，而非已提交的 step：由于前置监听器最先运行，当后续 `agent/step` 监听器取消或失败时其追加可能仍会保留，只追加的日志不做回滚。
+
+发布的 `./invariant` 伴生插件不注册任何运行时检查：读数是外部 tmux 状态的按轮快照，会话中不存在需要校验的跨事件关系，调度与格式由本包的管线测试固定。
+
+## 后果
+
+启动于 tmux 内的 agent 现在会以持久、带来源标记的上下文收到自身的 session/window/pane 位置及 window 布局，并在位置变化时按轮次更新。部署方通过 cordis.yml 选择启用；默认 spine 与随附示例保持沉默。在真实 tmux pane 之外——包括仅继承了 `$TMUX`／`$TMUX_PANE` 的终端——或没有 `ctx.bash` 执行器时，插件保持惰性且不报错，因此在任何地方组合它都安全。由于读数是一条持久的 `user/message`，它作为普通历史经受压缩，对系统提示装配与请求头毫无贡献，且每个发生变化的轮次至多花费一条两行消息。拉取模型在每个到期轮次的第一个 step 增加一次 bash 执行（经沙箱化的 bash seam）——内部包含一次 `ps` tty 探测、一次 `tmux display-message` tty 查询和字段查询。只有可选的间隔下限会抑制查询本身；位置是否变化只有在查询之后才知道，因此它只抑制注入。
+
+## 测试
+
+单元测试固定了：首个 step 的注入及来源/表层元数据；以 `$TMUX_PANE` 为键的命令（含其 `#{pane_tty}` 与 `ps -o tty=` 的比对守卫）；step 门槛；跨轮次的变化抑制与 pane 移动时的重新注入；正间隔抑制与阈值；每条空操作路径（无 bash、非零退出、字段数不符、pane id 为空、信号已取消）；前置排序先于普通 `agent/step` 监听器；对损坏的历史读数（非文本块、单行文本）的容错；以及配置对负值与非整数间隔的拒绝。逐文件覆盖率为 100%。
+
+## 考虑过的替代方案
+
+- **由 tmux hook / 后台监视器推送**——否决：需要在用户的 tmux 中安装 hook，并引入带清理的后台进程，只为换取按轮次上下文并不需要的步内新鲜度。
+- **每个 step 都运行**——否决：位置在一轮内稳定；重复查询只增加 token 成本而无新信息。以 `step === 1` 为门槛得到按轮次读数。
+- **裸 `child_process`**——否决：绕过沙箱/策略 seam，并手写 `ctx.bash` 执行器已拥有的子进程代码。
+- **包含 pane/window 像素尺寸**——否决：尺寸每次缩放都变动、徒增噪声；布局树已传达结构。
+- **用 `capture-pane` 抓取相邻 pane**——否决：庞大、嘈杂且涉及隐私；超出"自身位置"范围。
+- **动态系统提示区块**——否决：替换某个值会抹去支撑先前推理的历史读数且不可重建；单条持久且带来源的消息在每个位置变得可见时予以记录。
+- **信任 `$TMUX_PANE`（或 `$TMUX`）存在即可**——否决：两者都会被从 tmux shell 启动的终端（VS Code 集成终端）继承，于是非 pane 进程会注入陈旧位置。pane 的 `#{pane_tty}` 与本进程控制终端的比对才是决定性检查。
+- **对已知终端模拟器设黑名单（如 `TERM_PROGRAM=vscode`）**——否决：名单不完整且会不断增长，仍会漏掉其他启动器；tty 比对精确且与启动器无关。
+- **用运行时 invariant 校验每条读数的轮次、位置与格式**——最初随包发布，随后移除：它从日志中重新推导生产者自身的调度，并对同一个包刚刚渲染出的文本断言正则，因此只是重述 `apply()`，而非检查一条独立关系。它能报出的每种失败都必须先修改本包，而这些本包的管线测试已经覆盖。仅当出现插件自身并不计算的关系时才重新引入伴生检查——例如读数将来具备可被其他包破坏的跨轮次顺序或包裹义务。

+# Agent Note: Cross-workspace session resume
+
+Status: implemented
+
+English | [中文](2026-07-28-cross-workspace-resume.zh.md)
+
+## Problem
+
+`/resume` could only reach sessions started in the launch directory, so returning to yesterday's work in another project meant remembering its path, leaving the TUI, and relaunching there. Two independent causes produced that limit, and fixing either alone changes nothing.
+
+Storage was the binding one. The shipped `tui-demo` bundle defaulted `persistenceRoot` to a relative `./.sessions`, so each launch directory owned a disjoint JSONL root and a disjoint derived `session-query.db`. Sessions from another project were not filtered out of the listing — they were absent from the store the listing reads. The JSONL backend already partitions per-cwd *inside* one root, so the partitioning was doubled: once by root, once within it.
+
+The picker then filtered again. It dropped records whose `cwd` differed from the current session before display, and `summarizeResumeCandidate` independently marked a differing `cwd` as `disabledReason: 'different workspace'`, so a foreign session that did reach the store was both hidden and refused.
+
+Finally, resume never changed directory. The host re-execs `dsh --resume=<id>` through `process.execve`, which inherits the cwd. Session *header* cwd is restored from the log, but process cwd is what `dsh-fs-local`, the bash executor, and glob/grep resolve against, so resuming a foreign session would have replayed its transcript while acting on the wrong project.
+
+## Decision
+
+The dsh launcher supplies one session root under its Harness home through a boot slot, the picker gains a workspace scope, and the handoff carries the target directory.
+
+**Storage.** `dsh-paths` owns the location as `resolveSessionsRoot()` (`sessions` under the Harness home, by `resolveDshHome`'s precedence), but only the launcher assumes it: shared-store policy is the dsh CLI's, never a plugin's. The TUI surface provides the root through the `SESSIONS_ROOT_KEY` boot slot (`ctx.provide` before Loader entries mount) and `dsh web` patches the same root in `apps/cli/src/app-cli-entry.ts`. Two CLI surfaces computing that path independently is exactly the failure this change fixes — disjoint stores — so the fact gets one home rather than a `join` per caller, alongside the existing `registryRoot()` precedent for `run`.
+
+`tui-demo` itself keeps a project-local `./.sessions` default and reads the launcher slot between explicit config and that default (`config.persistenceRoot ?? ctx.get(SESSIONS_ROOT_KEY) ?? './.sessions'`). The precedence lives in `composeTuiApp`, not as a schemastery `.default()`, because a schema default would materialize before the compose function runs and shadow the slot for every Loader mount. `examples/tui-agent/cordis.yml` omits `persistenceRoot` so the launcher slot (or, for a bare example boot, the project-local default) applies. Configuring an explicit root always wins, which remains the correct choice for a hermetic deployment.
+
+**Scope, not exclusion.** A workspace other than the current one is a display scope rather than a disabled reason. `showResume()` summarizes every record and the `ResumePicker` owns a `scope` of `'workspace' | 'all'`, defaulting to the current workspace so the common case is unchanged. Tab toggles; the scope line names the active scope and the count the other holds; each row in the all-workspaces scope reports its own workspace, and that label joins the searchable text only in the scope that shows it. A toggle clears the query and selection so the highlighted row always belongs to the visible list, and the per-row workspace line makes a row one terminal row taller in that scope, which the visible-count budget accounts for.
+
+`summarizeResumeCandidate` therefore drops `'different workspace'` and gains `'session has no recorded workspace'`. That is a real new refusal rather than a rename: a header without `cwd` names no directory for the host to enter, so it cannot be handed off even though its log is intact.
+
+**Handoff.** `TuiResumeHost.handoff` takes the target `cwd` beside the `SessionId`. `preflightResume` resolves both together and returns them, so the caller cannot re-derive a stale directory from the row it displayed — a record whose `cwd` moved between listing and preflight is resumed in the *re-read* directory, which is why the former "reject a moved cwd" behavior is now a handoff with the new path. The shipped host chdirs before disposing the app: an unreachable directory must reject while the caller can still restore the terminal, because after teardown no owner remains to report to. `resumeArgs` keeps the `meta` subcommand form only when the target is this checkout, since `dsh meta` chdirs to the harness source itself and would override any other workspace.
+
+## Alternatives considered
+
+**Patch `persistenceRoot` from the `dsh` launcher instead of changing the bundle default.** Rejected after finding that a loader patch assigns `config` wholesale. The personal `~/.dsh/config.yaml` overlay already patches the `tui-agent` row with a partial config, which is exactly why `persistenceRoot` was falling back to the bundle default in the first place; a launcher patch would either be erased by that overlay or have to win over it and make the overlay unable to set the field. Owning the default in the bundle survives any partial patch and keeps one home for the fact.
+
+**Keep `./.sessions` and additionally scan the Harness-home root.** Rejected: two roots means two SQLite indexes and a merged listing whose rows have different liveness and revision authorities, to preserve visibility of logs that the no-migration decision already gives up.
+
+**Migrate existing project-local logs into the shared root.** Rejected by the requester. Sessions under a project's `./.sessions` stay on disk and stay resumable by explicit `dsh --resume <id>` from that directory, but no longer appear in `/resume`.
+
+**One flat list of every workspace.** Rejected: it loses the "this project" default that the overwhelmingly common case wants, and in a busy home directory the current project's sessions would compete with unrelated ones.
+
+**Let the host infer the directory from the restored session header.** Rejected: the header is model- and prompt-facing state restored *after* boot, while the directory must be entered *before* `execve`. Passing it explicitly keeps the ordering visible at the seam.
+
+## Consequences
+
+- Sessions already stored under a project-local `./.sessions` disappear from `/resume`. This is the accepted cost of no migration.
+- One shared root makes the pre-existing absence of a cross-process session lock reachable in one step: colliding used to require two terminals in the same directory, and is now one Tab away. `record.live` comes from the in-process `SessionQueryService`, so preflight rejects only sessions live in *this* runtime, while the JSONL backend takes no lock and two processes appending one log with independent `seq` counters would interleave. Closing this is no longer speculative hardening: `SessionRegistry.list()` already publishes live sessions cross-process under the same Harness home for `dsh list-sessions`, so consulting it in `summarizeResumeCandidate` is a small follow-up. It stays out of this change as pre-existing scope.
+- A resumed session can change the process's working directory, so a foreign resume is not a pure transcript restoration — every path-resolving tool moves with it.
+- The Harness home now holds session logs for every project on the machine. Its growth is no longer bounded by one checkout, and no retention policy is introduced here.
+
+## Testing
+
+TUI tests cover the default scope hiding other workspaces while reporting their count, Tab revealing them with per-row workspace labels, Tab back clearing the query and selection, searching by workspace label, a cwd-less record staying visible but disabled, and the handoff receiving both the id and the workspace re-read at preflight. The former "reject a moved cwd" case now asserts the handoff carries the new directory. `dsh-paths` tests pin `resolveSessionsRoot`'s precedence against `resolveDshHome`'s. `tui-demo` composition tests pin the project-local default and the derived `session-query.db` path. The keyless TUI snapshot pins both scopes of the selector, including the scope line, the per-row workspace lines, and the Tab hint in the footer. A manual cross-workspace resume verified at the process level that the replacement's working directory became the target workspace.

+# Agent Note: 跨 workspace 会话恢复
+
+Status: implemented
+
+[English](2026-07-28-cross-workspace-resume.md) | 中文
+
+## Problem
+
+`/resume` 只能触达在启动目录中创建的会话，因此要回到昨天在另一个项目里的工作，就得记住它的路径、退出 TUI、再到那里重新启动。造成这一限制的原因有两个，彼此独立，只修其中一个都不会有任何变化。
+
+存储是那个决定性的原因。已交付的 `tui-demo` 组合包把 `persistenceRoot` 默认成相对路径 `./.sessions`，于是每个启动目录都独占一份互不相交的 JSONL 根目录，以及一份互不相交的派生 `session-query.db`。来自另一个项目的会话并不是在列表中被过滤掉的——它们根本不存在于列表读取的存储中。JSONL 后端本来就会在*同一个*根目录*内部*按 cwd 分区，所以分区被叠加了两层：一层按根目录，一层在根目录内部。
+
+接着选择器又过滤了一次。它在展示前丢弃 `cwd` 与当前会话不同的记录，而 `summarizeResumeCandidate` 又独立地把不同的 `cwd` 标记为 `disabledReason: 'different workspace'`，于是一个确实进入了存储的外部会话既被隐藏，也会被拒绝。
+
+最后，恢复流程从不切换目录。宿主通过 `process.execve` 重新执行 `dsh --resume=<id>`，而它会继承 cwd。会话*头部*的 cwd 会从日志中还原，但 `dsh-fs-local`、bash 执行器以及 glob／grep 解析路径时依据的是进程 cwd，所以恢复一个外部会话会在回放它的 transcript（文本记录）的同时，作用到错误的项目上。
+
+## Decision
+
+dsh 启动器通过启动槽位提供其 Harness home 下的同一个会话根目录，选择器获得 workspace 范围，交接过程携带目标目录。
+
+**存储。** `dsh-paths` 以 `resolveSessionsRoot()` 拥有该位置（按 `resolveDshHome` 的优先级，取 Harness home 下的 `sessions`），但只有启动器假定它：共享存储策略属于 dsh CLI，绝不属于插件。TUI 界面通过 `SESSIONS_ROOT_KEY` 启动槽位（在 Loader 条目挂载前 `ctx.provide`）提供该根目录，`dsh web` 则在 `apps/cli/src/app-cli-entry.ts` 中为同一根目录打补丁。CLI 的两处界面各自独立计算该路径，正是本次改动所修复的那种失败——互不相交的存储——因此这项事实只有一个归属，而不是每个调用方各做一次 `join`，这与 `run` 已有的 `registryRoot()` 先例一致。
+
+`tui-demo` 自身保持项目本地的 `./.sessions` 默认值，并在显式配置与该默认值之间读取启动器槽位（`config.persistenceRoot ?? ctx.get(SESSIONS_ROOT_KEY) ?? './.sessions'`）。这一优先级放在 `composeTuiApp` 内，而不是写成 schemastery 的 `.default()`，因为 schema 默认值会在 compose 函数运行前物化，使每次 Loader 挂载都遮蔽该槽位。`examples/tui-agent/cordis.yml` 不写 `persistenceRoot`，因此启动器槽位（裸示例启动时则为项目本地默认值）生效。显式配置的根目录总是获胜，对于封闭部署来说这仍然是正确的选择。
+
+**是范围，不是排除。** 当前 workspace 之外的 workspace 是一种展示范围，而不是禁用理由。`showResume()` 汇总每一条记录，`ResumePicker` 持有一个 `'workspace' | 'all'` 的 `scope`，默认为当前 workspace，因此常见场景毫无变化。Tab 切换范围；范围行会说明当前生效的范围，以及另一个范围下的数量；在全 workspace 范围中每一行都报告自己的 workspace，而该标签只在展示它的范围里才加入可搜索文本。切换范围会清空查询和选中项，使高亮行始终属于可见列表；而逐行的 workspace 行会让该范围下的每一行在终端里多占一行，可见条数预算已经把这一点计入。
+
+因此 `summarizeResumeCandidate` 去掉了 `'different workspace'`，并新增 `'session has no recorded workspace'`。这是一条真正新增的拒绝理由，而不是改名：没有 `cwd` 的头部没有指明任何目录供宿主进入，所以即便它的日志完好也无法完成交接。
+
+**交接。** `TuiResumeHost.handoff` 在 `SessionId` 之外还接收目标 `cwd`。`preflightResume` 把两者一起解析并一起返回，因此调用方无法从它展示过的那一行里重新推导出一个陈旧目录——在列表展示与预检之间 `cwd` 发生了移动的记录，会在*重新读取到的*目录中恢复，这也是原先「拒绝已移动的 cwd」的行为如今变成携带新路径完成交接的原因。已交付的宿主在释放应用之前切换目录：不可达的目录必须在调用方还能恢复终端时就拒绝，因为拆卸之后已经没有任何所有者可供汇报。`resumeArgs` 只在目标就是本 checkout 时才保留 `meta` 子命令形式，因为 `dsh meta` 会切换到 harness 源码本身，从而覆盖任何其他 workspace。
+
+## Alternatives considered
+
+**从 `dsh` 启动器给 `persistenceRoot` 打补丁，而不是改动组合包默认值。** 在发现 loader 补丁会整体赋值 `config` 之后否决。个人的 `~/.dsh/config.yaml` 覆盖层已经用一份局部配置给 `tui-agent` 那一项打了补丁，这恰恰就是 `persistenceRoot` 一开始会退回到组合包默认值的原因；启动器补丁要么会被该覆盖层擦除，要么必须压过它，从而让覆盖层再也无法设置这个字段。把默认值放在组合包里能经受任何局部补丁，并让这项事实只有一个归属。
+
+**保留 `./.sessions`，并额外扫描 Harness home 根目录。** 否决：两个根目录意味着两份 SQLite 索引，以及一份合并列表——其中各行的活跃状态与版本权威来源并不相同，而这一切只是为了保住不做迁移的决策本就已经放弃的那部分日志可见性。
+
+**把现有的项目本地日志迁移到共享根目录。** 被需求方否决。项目 `./.sessions` 下的会话仍留在磁盘上，从该目录显式执行 `dsh --resume <id>` 仍可恢复，只是不再出现在 `/resume` 中。
+
+**把所有 workspace 铺成一个扁平列表。** 否决：这会丢掉绝大多数场景想要的「本项目」默认值，而在一个繁忙的 home 目录里，当前项目的会话会和无关会话争夺注意力。
+
+**让宿主从还原后的会话头部推断目录。** 否决：会话头部是面向模型与提示词的状态，在启动*之后*才还原，而目录必须在 `execve` *之前*进入。显式传递它能让这个顺序在边界处保持可见。
+
+## Consequences
+
+- 已经存放在项目本地 `./.sessions` 下的会话会从 `/resume` 中消失。这是不做迁移所接受的代价。
+- 同一个共享根目录让原本就缺失的跨进程会话锁一步之内即可触达：过去要造成冲突需要在同一个目录里开两个终端，如今只差一次 Tab。`record.live` 来自进程内的 `SessionQueryService`，因此预检只会拒绝在*本*运行时中处于活跃状态的会话，而 JSONL 后端不加任何锁，两个进程用各自独立的 `seq` 计数器追加同一份日志会互相交错。解决这一点已不再是投机性加固：`SessionRegistry.list()` 已经为 `dsh list-sessions` 在同一个 Harness home 下跨进程发布活跃会话，因此在 `summarizeResumeCandidate` 中查询它是一项小的后续工作。它作为既有范围之外的问题不纳入本次改动。
+- 恢复一个会话可以改变进程的工作目录，因此恢复外部会话不是单纯的 transcript 还原——每个解析路径的工具都会随之移动。
+- Harness home 现在保存着这台机器上每个项目的会话日志。它的增长不再受单个 checkout 约束，而本记录也没有引入任何保留策略。
+
+## Testing
+
+TUI 测试覆盖默认范围隐藏其他 workspace 但报告其数量、Tab 显示它们并带上逐行 workspace 标签、再按 Tab 返回时清空查询与选中项、按 workspace 标签搜索、无 cwd 的记录仍可见但不可选，以及交接同时收到 id 和在预检时重新读取到的 workspace。原先「拒绝已移动的 cwd」的用例现在断言交接携带新目录。`dsh-paths` 测试固定 `resolveSessionsRoot` 的优先级与 `resolveDshHome` 的一致。`tui-demo` 组合测试固定项目本地默认值以及派生出的 `session-query.db` 路径。无密钥 TUI 快照固定选择器的两个范围，包括范围行、逐行 workspace 行，以及页脚中的 Tab 提示。手动执行的一次跨 workspace 恢复在进程层面验证了替换后进程的工作目录变为目标 workspace。

+# Agent Note: `dsh migrate`/`dsh upgrade` seed the first turn with a skill
+
+Status: implemented
+
+English | [中文](2026-07-28-dsh-guided-skill-session-commands.zh.md)
+
+## Problem
+
+Two recurring flows begin with the user manually invoking one skill and answering its questions: migrating from another coding agent, and upgrading this checkout. Both require the user to know the skill exists and to type `/skill:dsh-migrate` or `/skill:dsh-upgrade` as the session's first turn. A dedicated entry command that drops the user straight into that guided session removes the discovery step.
+
+## Decision
+
+`dsh migrate` and `dsh upgrade` boot the ordinary TUI as a fresh session whose first turn auto-invokes a bundled skill (`dsh-migrate`, `dsh-upgrade`), exactly as if the user typed `/skill:<name>` and pressed Enter.
+
+The seed reuses the existing TUI skill path, not a new one. `createTuiChat` already has `invokeSkill(name, instructions)` — the code a typed `/skill:<name>` runs, including the "Unknown skill" notice. The launcher passes the skill name to the app through a new boot-context slot `INITIAL_SKILL_KEY` (`tuiInitialSkill`), mirroring `MAIN_SESSION_ID_KEY`/`TUI_GOODBYE_MESSAGE_KEY`: `ctx.provide` is the only channel from launcher argv into a Loader-mounted plugin. The TUI's `apply()` reads the slot and folds it into `config.initialSkill`; after `ui.start()` succeeds, `createTuiChat` fires `invokeSkill(config.initialSkill, '')` once when set.
+
+**Freshness is gated in the launcher, not the TUI.** `runSkillSession` always mints a fresh session and provides the slot only when `resumeSessionId === undefined`, so a later `dsh --resume <id>` of that session is an ordinary TUI session with no re-injection. The TUI stays generic: it invokes whatever skill it is handed, once, at startup.
+
+**`migrate`/`upgrade` take no options.** Unlike `meta`, they carry no `--resume`, `--config`, or `-p`; a guided fresh-session entry has nothing to resume or reconfigure. Any leaked default-surface option fails loud, matching the `web`/`meta` rejection pattern in the Commander adapter. The two modes share one `SkillSessionInvocation` discriminant (`mode: 'migrate' | 'upgrade'`); `bin.ts` maps the mode to `dsh-${mode}`.
+
+The `dsh-migrate` skill is bundled under `skills/` (shipped through `DSH_BUNDLED_SKILL_DIR`, like `dsh-upgrade`). It asks which source agent (opencode/pi/Claude Code/Codex) if unstated, then maps each capability — workspace instructions, personal overlay, skills, hooks, MCP, API/env — to its DSH equivalent, grounded in the actual repo surfaces (the `hooks-claude`/`hooks-codex` bridges, `~/.dsh/{config.yaml,.env,AGENTS.md,skills/}`, `AGENTS.md`/`CLAUDE.md`, `mcporter`), and states plainly when a capability has no equivalent.
+
+## Testing
+
+`apps/cli/tests/args.spec.ts` gains routing for `migrate`/`upgrade` (bare discriminant) and exit-1 for every leaked option on either side of each subcommand.
+
+`packages/ui/tui/tests/tui.spec.ts` gains two fake-terminal cases in the existing skill describe block: `config.initialSkill` set delivers the rendered skill body as the first turn with no user input, and an unknown initial skill reports a notice without sending. `runSkillSession` itself is composition inside the module's `v8 ignore` block, like `runTui`/`runMeta`.
+
+No keyless PTY snapshot: per the maintainer's scope call for this change, unit coverage plus interactive verification suffices, and the seed rides the already-snapshotted `/skill:` render path. Both commands were verified interactively in tmux from a scratch cwd: `dsh migrate` loaded `dsh-migrate` and asked which source agent; `dsh upgrade` loaded `dsh-upgrade`, which pulled in `dsh-customize` and began checkout discovery.
+
+## Alternatives considered
+
+**Prefill the input and let the user press Enter.** Rejected: needs a new editor-prefill seam and still requires a keystroke. Auto-submit reuses `invokeSkill` and delivers the intended one-command entry.
+
+**Seed a natural-language instruction ("use the dsh-migrate skill…") instead of `/skill:<name>`.** Rejected here: the literal skill-invocation path renders the skill body into the first turn deterministically, identical to the manual command, rather than depending on the model choosing to load the skill.
+
+**Support `--resume` on `migrate`/`upgrade`.** Rejected: these are one-shot guided entries. A resumed session is an ordinary TUI session reachable through the default surface's `dsh --resume <id>`; re-injecting the skill on resume would duplicate the first turn.
+
+**Read `INITIAL_SKILL_KEY` in the app bundle (like `MAIN_SESSION_ID_KEY`) rather than in the TUI's `apply()`.** Not needed: `initialSkill` is a TUI `Config` field consumed in `createTuiChat`, so folding the slot into config at the TUI entry keeps it beside the other launcher-owned runtime reads (`tuiResumeHost`, `tuiGoodbyeMessage`) and leaves the app bundle unchanged.
+
+## Consequences
+
+Migrating or upgrading is one command from anywhere, with the guiding skill already invoked. The launcher→TUI initial-skill slot is reusable by any future guided-session command; the TUI's contract is "invoke this named skill once at startup," and freshness/resume policy stays with the launcher that owns session identity. The [TUI skill slash command](2026-07-21-tui-skill-slash-command.md) remains the mechanism; this note adds a launcher-driven auto-invocation of it and does not supersede it.

+# Agent Note：`dsh migrate`/`dsh upgrade` 以 skill 播种首轮
+
+Status: implemented
+
+[English](2026-07-28-dsh-guided-skill-session-commands.md) | 中文
+
+## 问题
+
+有两个反复出现的流程都以用户手动调用某个 skill 并回答其问题开始：从其他编码 agent 迁移，以及升级本 checkout。二者都要求用户知道该 skill 存在，并把 `/skill:dsh-migrate` 或 `/skill:dsh-upgrade` 作为会话首轮键入。一个专用入口命令若能让用户直接进入该引导式会话，便可省去这一发现步骤。
+
+## 决策
+
+`dsh migrate` 与 `dsh upgrade` 以全新会话启动普通 TUI，其首轮自动调用一个内置 skill（`dsh-migrate`、`dsh-upgrade`），效果等同于用户键入 `/skill:<name>` 并回车。
+
+播种复用现有的 TUI skill 路径，而非新增一条。`createTuiChat` 已有 `invokeSkill(name, instructions)`——即键入 `/skill:<name>` 所走的代码，包含“未知 skill”通知。启动器通过一个新的启动上下文槽 `INITIAL_SKILL_KEY`（`tuiInitialSkill`）把 skill 名称传给应用，与 `MAIN_SESSION_ID_KEY`/`TUI_GOODBYE_MESSAGE_KEY` 一致：`ctx.provide` 是从启动器 argv 进入 Loader 挂载插件的唯一通道。TUI 的 `apply()` 读取该槽并折叠进 `config.initialSkill`；`ui.start()` 成功后，`createTuiChat` 在其被设置时调用一次 `invokeSkill(config.initialSkill, '')`。
+
+**新鲜性在启动器而非 TUI 中把关。** `runSkillSession` 总是创建全新会话，且仅在 `resumeSessionId === undefined` 时提供该槽，因此之后 `dsh --resume <id>` 恢复该会话时是普通 TUI 会话，不会重复注入。TUI 保持通用：它只是把接到的 skill 在启动时调用一次。
+
+**`migrate`/`upgrade` 不接受任何选项。** 与 `meta` 不同，它们不带 `--resume`、`--config` 或 `-p`；引导式全新会话入口没有可恢复或可重配置的内容。任何泄漏的默认界面选项都会明确报错，与 Commander 适配器中 `web`/`meta` 的拒绝模式一致。两个 mode 共用一个 `SkillSessionInvocation` 判别式（`mode: 'migrate' | 'upgrade'`）；`bin.ts` 将 mode 映射为 `dsh-${mode}`。
+
+`dsh-migrate` skill 内置于 `skills/`（经 `DSH_BUNDLED_SKILL_DIR` 交付，与 `dsh-upgrade` 相同）。若未说明源 agent，它会先询问是哪个（opencode/pi/Claude Code/Codex），再把每项能力——workspace 指令、个人覆盖、skills、hooks、MCP、API/env——映射到对应的 DSH 等价物，并基于仓库实际的表面（`hooks-claude`/`hooks-codex` 桥、`~/.dsh/{config.yaml,.env,AGENTS.md,skills/}`、`AGENTS.md`/`CLAUDE.md`、`mcporter`）落地；当某能力无等价物时明确说明。
+
+## 测试
+
+`apps/cli/tests/args.spec.ts` 新增 `migrate`/`upgrade` 的路由（裸判别式），以及每个子命令两侧任一泄漏选项的退出码 1。
+
+`packages/ui/tui/tests/tui.spec.ts` 在既有 skill describe 块中新增两个伪终端用例：设置 `config.initialSkill` 时无需用户输入即把渲染后的 skill 正文作为首轮投递；未知的初始 skill 以通知形式报告且不发送。`runSkillSession` 本身是模块 `v8 ignore` 块内的组装，与 `runTui`/`runMeta` 相同。
+
+无 keyless PTY 快照：依据维护者对本次改动的范围裁定，单元覆盖加交互式验证已足够，且播种走的是已有快照的 `/skill:` 渲染路径。两个命令均已在 tmux 中从临时 cwd 交互式验证：`dsh migrate` 加载 `dsh-migrate` 并询问源 agent；`dsh upgrade` 加载 `dsh-upgrade`，后者引入 `dsh-customize` 并开始 checkout 发现。
+
+## 考虑过的替代方案
+
+**预填输入框并让用户按回车。** 已否决：需要新增编辑器预填 seam，且仍需一次按键。自动提交复用 `invokeSkill`，实现预期的一命令入口。
+
+**播种自然语言指令（“使用 dsh-migrate skill……”）而非 `/skill:<name>`。** 在此否决：字面 skill 调用路径会确定性地把 skill 正文渲染进首轮，与手动命令完全一致，而不依赖模型自行选择加载该 skill。
+
+**在 `migrate`/`upgrade` 上支持 `--resume`。** 已否决：它们是一次性引导入口。恢复的会话是可经默认界面 `dsh --resume <id>` 到达的普通 TUI 会话；恢复时重新注入 skill 会重复首轮。
+
+**在应用 bundle 中读取 `INITIAL_SKILL_KEY`（像 `MAIN_SESSION_ID_KEY` 那样）而非在 TUI 的 `apply()` 中。** 无此必要：`initialSkill` 是在 `createTuiChat` 中消费的 TUI `Config` 字段，因此在 TUI 入口处把该槽折叠进 config，可与其他启动器拥有的运行时读取（`tuiResumeHost`、`tuiGoodbyeMessage`）并列，且无需改动应用 bundle。
+
+## 后果
+
+迁移或升级从任何位置都只需一条命令，且引导 skill 已被调用。启动器→TUI 的初始 skill 槽可被未来任何引导式会话命令复用；TUI 的契约是“在启动时调用一次这个具名 skill”，而新鲜性/恢复策略留在拥有会话身份的启动器一侧。[TUI skill 斜杠命令](2026-07-21-tui-skill-slash-command.md)仍是该机制；本 note 在其之上新增了一个由启动器驱动的自动调用，并未取代它。

+# Agent Note: `dsh meta` boots the TUI over the harness checkout
+
+Status: implemented
+
+English | [中文](2026-07-28-dsh-meta-source-workspace.zh.md)
+
+## Problem
+
+`dsh` treats the invoking directory as the workspace, which is what makes it useful on arbitrary projects. Working on dsh itself therefore means `cd`-ing to the checkout first — and the checkout is not a memorable path: the source install keeps it under a container directory as a timestamped staging worktree (`~/.dsh/source/staging-<timestamp>`) behind a `current` symlink, so the target moves on every upgrade. The agent is already *told* where its source lives by the `harness:source` prompt section, and the `cordis` toolset can modify that runtime, but the human still had to locate the directory by hand to start a session there.
+
+## Decision
+
+`dsh meta` boots the ordinary TUI with the harness checkout as the workspace, from any directory.
+
+The target is `SOURCE_ROOT` in `apps/cli/src/tui.ts` — `fileURLToPath(new URL('../../..', import.meta.url))`, three hops up from `apps/cli/{src,lib}` — the same constant the `harness:source` prompt section already names, so the workspace and the path advertised to the model cannot drift. It follows the launcher's real path, so a PATH symlink through `current` resolves to whichever staging worktree is active.
+
+The mechanism is one `process.chdir(workspace)` inside `runTui`, guarded by a new optional third parameter that only `runMeta` passes. The cwd *is* the workspace seam in the shipped tree: `examples/tui-agent/cordis.yml` derives the session cwd (`!!js process.cwd()`), the `./.sessions` persistence root, and the HMR watch root (`root: ['.']`) from it, so one chdir moves all three together and meta sessions land in the checkout's gitignored `.sessions/`. It runs after both `.env` layers are loaded — the bin's invoking-directory load and the personal one — so the ambient > project > personal precedence is untouched. `DEFAULT_CONFIG` and `SOURCE_ROOT` are absolute and TUI mode passes no snapshot mode, so config resolution is chdir-independent.
+
+`meta` accepts only `--resume <id>`. `--config` would boot a foreign tree against the harness workspace, which is the `--config` case rather than this one; `-p` is not interactive. Both fail loud, as does an empty `--resume=` — matching the default surface, where a swallowed empty id would silently start a fresh session.
+
+**`meta` does not redeclare `--resume`.** Commander parses an option a subcommand shares with its parent into `program.opts()` and leaves the subcommand's own options object empty, so redeclaring it silently dropped the id (found by probing the adapter, not by review). The action reads `program.opts()`, which also accepts the flag on either side of the subcommand; `--help` still lists it among the parent's options.
+
+## Testing
+
+`apps/cli/tests/args.spec.ts` extends its two existing cases rather than adding a file: routing for `meta`, `meta --resume <id>`, and `--resume <id> meta` (pinning the shared-option behavior above), and exit-1 for `meta --resume=`, `meta --config`, and `meta -p`. `runMeta` itself is composition inside the module's existing `v8 ignore` block, like `runTui`.
+
+There is no keyless PTY smoke for this mode. The smoke harness gives each run a temp cwd, but `dsh meta` deliberately chdirs to the real checkout, so a smoke would write `.sessions/` into the live tree mid-test. Covering it properly needs an injectable target directory — a test-only seam this note declines to add for a one-line chdir.
+
+The mode was verified interactively instead. Launched from `$HOME`, a `pwd` tool call reports the checkout, git resolves to its branch, the session log lands under the checkout's `.sessions/` (leaving `~/.sessions` untouched and the tree free of unignored residue), and plain `dsh` from another directory still uses the invoking one.
+
+`dsh meta --resume <valid-id>` once started a *fresh* session instead of resuming — a pre-existing defect on the default surface, not one this mode introduced. [Launcher-owned resume identity](../architecture/2026-07-28-launcher-owned-resume-identity.md) found the cause and fixed it: a personal overlay had replaced the whole `tui-agent` config block, overwriting the shipped `resumeSessionId` intake with a read of an unset environment variable, so a valid id was silently ignored. Session identity is now a launcher-owned context slot that no config key can displace, and `meta` routes through it.
+
+## Alternatives considered
+
+**Thread an explicit workspace through `boot` and the config tree.** Avoids mutating process-wide state, but the shipped config reads the cwd in three places (`!!js process.cwd()`, `persistenceRoot`, HMR `root`), so each would need its own new plumbing and config key to stay consistent. `chdir` before boot expresses "this is the workspace" once, at the seam that already means it.
+
+**A `--meta` flag on the default surface.** Rejected: the default surface is option-only so that subcommands do not collide with a positional, and a flag that silently relocates the workspace reads as a modifier of the current directory rather than a different target. `meta` alongside `web` matches the existing shape.
+
+**Resolve `~/.dsh/source/current` instead of the launcher's own path.** Rejected: it would diverge from the `harness:source` prompt path whenever a non-installed checkout's `bin/dsh` is invoked directly, telling the model one source root while working in another.
+
+**Make the printed resume hint mode-aware.** Deferred here as a known cost, then delivered by [launcher-owned resume identity](../architecture/2026-07-28-launcher-owned-resume-identity.md): the exit line became a launcher-provided context slot, so meta mode prints `dsh meta --resume <id>` and a copied hint works from any directory. It previously came from static config as `dsh --resume {session}` and only worked when re-run from the checkout.
+
+## Consequences
+
+Starting a session on dsh's own source is `dsh meta` from anywhere, and the workspace is guaranteed to be the same checkout the model is told about. Meta sessions are isolated in the checkout's `.sessions/`, so `dsh meta --resume` sees only other meta sessions — intended, since a session's logged cwd belongs to its workspace.
+
+The resume hint was this mode's original cost and is now resolved. [Launcher-owned resume identity](../architecture/2026-07-28-launcher-owned-resume-identity.md) made both the printed line and the in-place `/resume` handoff reproduce the mode as `dsh meta --resume <id>` from one shared argv helper, so a copied hint works from any directory and the handoff no longer depends implicitly on `execve` preserving the process cwd.
+
+`runTui` gains an optional third parameter, so the workspace override is visible at the one function that owns TUI composition rather than hidden in a second copy of it.

+# Agent Note：`dsh meta` 以 harness 检出为 workspace 启动 TUI
+
+Status: implemented
+
+[English](2026-07-28-dsh-meta-source-workspace.md) | 中文
+
+## Problem
+
+`dsh` 把调用目录视为 workspace，这正是它能作用于任意项目的原因。但因此，开发 dsh 自身就得先 `cd` 到检出目录——而该目录并不是一个好记的路径：源码安装会把它放在一个容器目录下、作为带时间戳的 staging 工作树（`~/.dsh/source/staging-<timestamp>`），并由 `current` 符号链接指向，因此每次升级后目标都会变化。`harness:source` 提示词段已经*告知* agent 其源码位置，`cordis` 工具集也能修改该运行时，但人类仍需手工定位该目录才能在其中开始会话。
+
+## Decision
+
+`dsh meta` 在任意目录下都以 harness 检出为 workspace 启动普通 TUI。
+
+目标是 `apps/cli/src/tui.ts` 中的 `SOURCE_ROOT`——`fileURLToPath(new URL('../../..', import.meta.url))`，从 `apps/cli/{src,lib}` 向上三级——与 `harness:source` 提示词段所用的常量完全相同，因此 workspace 与告知模型的路径不可能发生偏离。它跟随启动器的真实路径，所以经由 `current` 的 PATH 符号链接会解析到当前生效的那个 staging 工作树。
+
+机制是 `runTui` 内的一次 `process.chdir(workspace)`，由一个新的可选第三参数把守，只有 `runMeta` 会传入。在已交付的配置树中，cwd *就是* workspace 的接缝：`examples/tui-agent/cordis.yml` 由它派生出会话 cwd（`!!js process.cwd()`）、`./.sessions` 持久化根目录以及 HMR 监视根目录（`root: ['.']`），因此一次 chdir 会让三者一并移动，meta 会话则落在检出目录中被 gitignore 的 `.sessions/` 内。它在两层 `.env` 都加载之后执行——bin 对调用目录的加载与个人层加载——因此“环境中已有的值 > 项目 > 个人”的优先级不受影响。`DEFAULT_CONFIG` 与 `SOURCE_ROOT` 都是绝对路径，且 TUI 模式不传 snapshot mode，所以配置解析与 chdir 无关。
+
+`meta` 只接受 `--resume <id>`。`--config` 会以 harness workspace 启动其他配置树，那属于 `--config` 的场景而非本场景；`-p` 并非交互式。两者都会明确报错，空的 `--resume=` 亦然——与默认界面一致，在那里被吞掉的空 id 会静默开启一个新会话。
+
+**`meta` 不重新声明 `--resume`。** 对于子命令与父命令共享的选项，Commander 会将其解析进 `program.opts()`，而把子命令自身的 options 对象留空；因此重新声明会静默丢弃该 id（这是通过实测适配器发现的，而非评审发现）。action 读取 `program.opts()`，这同时也允许该标志出现在子命令的任意一侧；`--help` 仍会在父命令的选项中列出它。
+
+## Testing
+
+`apps/cli/tests/args.spec.ts` 扩展其已有的两个用例而非新增文件：`meta`、`meta --resume <id>` 与 `--resume <id> meta` 的路由（钉住上述共享选项行为），以及 `meta --resume=`、`meta --config`、`meta -p` 的退出码 1。`runMeta` 自身与 `runTui` 一样，属于该模块既有 `v8 ignore` 块内的组合代码。
+
+该 mode 没有 keyless PTY 冒烟测试。冒烟框架会为每次运行提供临时 cwd，但 `dsh meta` 刻意 chdir 到真实检出目录，因此冒烟测试会在测试中途把 `.sessions/` 写入实际工作树。要正确覆盖它需要一个可注入的目标目录——为了一行 chdir 而引入的测试专用 seam，本 note 不予采纳。
+
+取而代之的是交互式验证。从 `$HOME` 启动后，`pwd` 工具调用报告的是该检出目录，git 解析到其分支，会话日志落在该检出的 `.sessions/` 下（`~/.sessions` 未被触及，工作树也没有未被忽略的残留），并且从其他目录运行的普通 `dsh` 仍使用调用目录。
+
+`dsh meta --resume <有效 id>` 曾经开启一个*新*会话而非恢复——这是默认界面上既已存在的缺陷，并非本 mode 引入。[由启动器持有的会话身份与退出行](../architecture/2026-07-28-launcher-owned-resume-identity.md) 查明了原因并将其修复：一个个人 overlay 替换了整个 `tui-agent` 配置块，用对一个未设置的环境变量的读取覆盖了已交付的 `resumeSessionId` 入口，因此有效的 id 会被静默忽略。会话标识如今是一个启动器拥有的上下文槽位，没有任何配置键能取代它，而 `meta` 经由它进行路由。
+
+## Alternatives considered
+
+**通过 `boot` 与配置树显式传递 workspace。** 这可避免修改进程级状态，但已交付的配置在三处读取 cwd（`!!js process.cwd()`、`persistenceRoot`、HMR `root`），每一处都需要各自新增管线与配置键才能保持一致。启动前 chdir 只在本就表达该含义的接缝上表达一次“这就是 workspace”。
+
+**在默认界面上加一个 `--meta` 标志。** 拒绝：默认界面是纯选项形式，以免子命令与位置参数冲突；而一个会静默改变 workspace 的标志读起来像是对当前目录的修饰，而非另一个目标。`meta` 与 `web` 并列符合既有形态。
+
+**解析 `~/.dsh/source/current` 而非启动器自身路径。** 拒绝：当直接调用某个非安装检出的 `bin/dsh` 时，它会与 `harness:source` 提示词路径产生偏离——告知模型一个源码根目录，却在另一个目录中工作。
+
+**让打印的恢复提示随 mode 变化。** 在此作为已知代价推迟，随后由 [由启动器持有的会话身份与退出行](../architecture/2026-07-28-launcher-owned-resume-identity.md) 交付：退出行变成了一个启动器提供的上下文槽位，因此 meta 模式打印 `dsh meta --resume <id>`，被复制的提示在任意目录下都有效。它此前来自静态配置，固定为 `dsh --resume {session}`，且只有在检出目录中重新运行才有效。
+
+## Consequences
+
+在 dsh 自身源码上开启会话变成了在任意位置执行 `dsh meta`，且该 workspace 必然就是告知模型的那个检出目录。meta 会话被隔离在检出目录的 `.sessions/` 内，因此 `dsh meta --resume` 只能看到其他 meta 会话——这是预期行为，因为会话记录的 cwd 属于它的 workspace。
+
+恢复提示曾是本 mode 的原初代价，如今已解决。[由启动器持有的会话身份与退出行](../architecture/2026-07-28-launcher-owned-resume-identity.md) 让打印的行与原地 `/resume` 移交都从同一个共享的 argv 辅助函数将该 mode 复现为 `dsh meta --resume <id>`，因此被复制的提示在任意目录下都有效，且移交不再隐式依赖于 `execve` 保留进程 cwd。
+
+`runTui` 新增一个可选第三参数，因此 workspace 覆盖是在拥有 TUI 组合逻辑的那唯一一个函数上可见的，而不是隐藏在它的第二份副本中。

+# Agent Note: live-session registry and `dsh list-sessions`
+
+Status: implemented
+
+English | [中文](2026-07-28-live-session-registry-and-dsh-ls.zh.md)
+
+## Problem
+
+Nothing could answer "which dsh sessions am I running right now". A user with sessions across several projects had no way to enumerate them, and no way to recover the id needed for `--resume` except the exit line of the terminal that printed it. Session persistence records every session that ever existed, so it cannot answer the question: it has no notion of liveness, and no `process.pid` appeared anywhere in the session, persistence, or storage packages.
+
+## Decision
+
+`dsh list-sessions` (alias `dsh ps`) lists the sessions running right now — session id, pid, uptime, workspace, title — newest first, across every workspace, with `--json` for machines. Three packages back it, as a capability seam.
+
+[`dsh-session-registry`](../../../../packages/session-registry/session-registry/README.md) (`ctx.sessionRegistry`) is the seam: the abstract service contract and record vocabulary, so the medium can later move to a database without touching consumers. [`dsh-session-registry-file`](../../../../packages/session-registry/session-registry-file/README.md) implements it over one lock-guarded JSON file under the Harness home. [`dsh-session-registry-live`](../../../../packages/session-registry/session-registry-live/README.md) follows `session/created`, `session/disposed`, and `session/title` and keeps the registry in step. `apps/cli` mounts both on every launcher surface — the TUI, `dsh meta`, headless, and web — and `dsh list-sessions` mounts only the service, booting no agent tree. No surface label is recorded: a launcher's mode is not a property of the session, and the workspace column already distinguishes a `dsh meta` session from a project one.
+
+### Liveness is derived, never stored
+
+`list()` probes each record's pid with `kill(pid, 0)` and drops the dead ones, writing the pruned result back. A process killed without running its disposer leaves a record that the next read removes, so there is no daemon, no heartbeat, and no permanent phantom. A per-process `bootId` distinguishes a recycled pid, so deregistration cannot delete a namesake record from a different incarnation. `EPERM` counts as alive: a live session owned by another user must not be dropped.
+
+### Two independent concurrency layers
+
+The file is written by every dsh process and by several sessions inside one process, and the two cases need different mechanisms.
+
+Across processes, each read-modify-write holds a [`proper-lockfile`](https://github.com/moxystudio/node-proper-lockfile) advisory lock. Within one process, calls queue on an internal chain, because the advisory lock is tracked per process: overlapping same-process callers contend for its bounded retry budget rather than queueing, and past roughly a dozen concurrent calls that budget runs out and a registration rejects. Since publication is fire-and-forget, such a rejection silently drops a live session from the listing — the exact "listing that lies" failure this feature exists to avoid. Both layers are load-bearing and each is pinned by a test that fails without it.
+
+### Records carry their own title
+
+The title is the one mutable field, replaced through `retitle` as `session/title` events arrive. It lives in the record rather than being read from the session log because the log's location, format, and compression are per-deployment backend choices: the TUI writes project-local zstd-compressed JSONL, the web and headless surfaces write to a global root, a user profile overrides either, and SQLite has no per-session file at all. An independent reader cannot portably parse that, so `dsh list-sessions` opens no log and assumes no backend.
+
+### Subagents are invisible by construction
+
+Only top-level launcher surfaces mount the publisher. In-process subagents (`spawn`, `fork`) have no process of their own, and the out-of-process backends spawn `dsh-jsonrpc-agent` rather than this CLI. No filter flag is needed, and no subagent package changed.
+
+## Alternatives considered
+
+**One file per session under `~/.dsh/run/`.** No lock at all, since each process only writes and deletes its own file. Rejected in favour of the single file the user chose, which then made a real advisory lock mandatory rather than optional.
+
+**A domain over the `storage-json` backend.** The obvious reuse, and wrong: that backend documents "no cross-process write locking … last write wins" and names single-host-process as its assumption, and the [domain KV storage note](../../proposed/architecture/2026-07-24-domain-kv-storage-and-workspace.md) puts multi-process explicitly out of scope. A registry written concurrently by every launcher is precisely that excluded case. Widening the backend's contract would have changed a shipped guarantee for one consumer; a separate package owns the multi-process medium instead.
+
+**Hand-rolled `O_EXCL` lock directory.** Rejected under the [dependencies-over-hand-rolling policy](../process/2026-07-26-dependencies-over-hand-rolling.md): stale-lock detection, retry backoff, and compromise handling are exactly the surface a maintained dependency should own.
+
+**Accept last-write-wins on the single file.** Cheapest to build, and it silently omits real running sessions when two start close together. A listing tool that lies is worse than no listing tool.
+
+**Read the title from the session log in `dsh list-sessions`.** Implemented first, then verified live: the shipped TUI writes `session.jsonl.zstd`, whose frame helpers are internal to the jsonl backend. Exporting them would have hard-coded one backend's file format into the CLI and still shown nothing for SQLite.
+
+**Register the web server itself with a placeholder session id.** `dsh web` owns no session — its sessions are created later by browser clients — so a server row would have put a fake id in a session table. Following session lifecycle instead makes browser sessions appear and disappear as they are opened, which also subsumed the TUI's launcher-side registration and deleted that separate path.
+
+**A `--here`/`--workspace` filter.** Dropped on request: the listing is always global, and narrowing is the user's `grep`.
+
+## Consequences
+
+The registry is an observability aid, so every write is best-effort: a registry fault warns and never fails a working agent session. The cost is that a listing can lag reality by one failed write, healed by the next.
+
+Title mirroring costs one locked read-modify-write per revision, so an aggressive retitling cadence pays that write each time.
+
+`bootId` bounds pid reuse only for records this process wrote. A foreign record whose pid the operating system has reassigned to an unrelated live process is reported alive until its owner removes it — accepted because the portable alternative, reading real process start times, is `/proc`-only.
+
+Liveness is pid existence, not health: a hung process still lists as running. The registry deliberately makes no progress judgement.
+
+## Testing
+
+Unit coverage pins durable-format validation (torn text, foreign version, per-row damage that must not hide siblings), pid pruning against a genuinely reaped pid, `EPERM`-is-alive, incarnation-scoped deregistration, and `retitle` scoping. Both concurrency layers have a regression test verified to fail when its mechanism is removed: 8 real processes for the cross-process lock, 24 overlapping in-process calls for the chain. The publisher is tested over the real `SessionStore` rather than a hand-built emitter, because publication depends on the store's actual lifecycle dispatch.
+
+Verified live in tmux against the assembled application: two concurrent TUI sessions in different workspaces both listed, a title appeared after the first turn, clean exit deregistered, and `SIGKILL` left a stale record that the next `dsh list-sessions` pruned and durably rewrote.

+# Agent Note: 活跃会话注册表与 `dsh list-sessions`
+
+Status: implemented
+
+[English](2026-07-28-live-session-registry-and-dsh-ls.md) | 中文
+
+## 问题
+
+没有任何东西能回答「我此刻正在运行哪些 dsh 会话」。会话散落在多个项目中的用户既无法枚举它们，也无法找回 `--resume` 所需的 id，唯一的来源是打印过它的那个终端的退出行。会话持久化记录了曾经存在过的每个会话，因此它答不了这个问题：它没有存活状态的概念，而且 session、persistence、storage 这几个包里任何位置都没有出现过 `process.pid`。
+
+## 决策
+
+`dsh list-sessions`（别名 `dsh ps`）列出此刻正在运行的会话（会话 id、pid、运行时长、工作区、标题），最新的排在最前，覆盖所有工作区，并提供面向机器的 `--json`。背后由三个包（package）以能力 seam 的形式支撑。
+
+[`dsh-session-registry`](../../../../packages/session-registry/session-registry/README.md)（`ctx.sessionRegistry`）是 seam：抽象服务契约与记录词汇，使介质将来可以换成数据库而不触及消费方。[`dsh-session-registry-file`](../../../../packages/session-registry/session-registry-file/README.md) 在 Harness home 下的一个加锁保护的 JSON 文件上实现它。[`dsh-session-registry-live`](../../../../packages/session-registry/session-registry-live/README.md) 跟随 `session/created`、`session/disposed` 和 `session/title`，让注册表保持同步。`apps/cli` 在每个启动方接口（TUI、`dsh meta`、headless、web）上都挂载这两个包，而 `dsh list-sessions` 只挂载该服务，不启动任何 agent（智能体）树。不记录任何接口标签：启动方的模式并不是会话的属性，而工作区那一列已经能把 `dsh meta` 会话和项目会话区分开。
+
+### 存活状态是推导出来的，绝不存储
+
+`list()` 用 `kill(pid, 0)` 探测每条记录的 pid，剪除已消亡的记录，并把剪除后的结果写回。未运行 disposer（资源释放）就被杀掉的进程留下的记录，会被下一次读取移除，因此不需要 daemon，不需要心跳，也不会有永久残留的幽灵记录。每个进程独有的 `bootId` 用于区分被复用的 pid，因此注销不会删除属于另一个 incarnation 的同名记录。`EPERM` 算作存活：归属于另一个用户的存活会话绝不能被丢掉。
+
+### 两层相互独立的并发机制
+
+该文件既被每个 dsh 进程写入，也被同一进程内的多个会话写入，这两种情形需要不同的机制。
+
+跨进程时，每次读-改-写都持有一个 [`proper-lockfile`](https://github.com/moxystudio/node-proper-lockfile) 咨询锁。进程内则由各次调用在内部链上排队，因为咨询锁是按进程跟踪的：同一进程中重叠的调用方会争抢它有界的重试预算，而不是排队等待；大约超过十几次并发调用后，该预算耗尽，某次注册就会被拒绝。由于发布采用 fire-and-forget 方式，这样一次拒绝会静默地把一个存活会话从列表中丢掉——而这正是本功能要避免的「列表说谎」故障。两层机制都是必需的，且各有一个测试固定它：移除该机制，对应测试就会失败。
+
+### 记录自带标题
+
+标题是唯一的可变字段，随 `session/title` 事件到达，通过 `retitle` 替换。它存放在记录里，而不是从会话日志读取，因为日志的位置、格式和压缩都是逐部署的后端选择：TUI 写入项目本地的 zstd 压缩 JSONL，web 与 headless 界面写入全局根目录，用户配置文件可以覆盖二者，而 SQLite 根本没有逐会话的文件。独立读取方无法以可移植的方式解析这些内容，因此 `dsh list-sessions` 不打开任何日志，也不假定任何后端。
+
+### subagent 在设计上就不可见
+
+只有顶层启动方接口才挂载发布方。进程内 subagent（`spawn`、`fork`）没有自己的进程，而进程外后端 spawn 的是 `dsh-jsonrpc-agent` 而不是本 CLI（命令行界面）。不需要任何过滤开关，也没有改动任何 subagent 包。
+
+## 考虑过的替代方案
+
+**在 `~/.dsh/run/` 下每个会话一个文件。** 完全不需要锁，因为每个进程只写入和删除自己的文件。不予采纳，改用用户选定的单文件方案，而这也使真正的咨询锁从可选变为必需。
+
+**在 `storage-json` 后端之上做一个 domain。** 这是最显而易见的复用，但它是错的：该后端明确记载「无跨进程写锁……最后写入者胜出」，并把单一宿主进程列为自身前提，而[domain KV 存储 note](../../proposed/architecture/2026-07-24-domain-kv-storage-and-workspace.md)明确把多进程排除在范围之外。被每个启动方并发写入的注册表恰恰就是这个被排除的场景。放宽该后端的契约，等于为一个消费方改动一项已上线的保证；改由一个独立的包拥有这套多进程介质。
+
+**手写 `O_EXCL` 锁目录。** 依据[优先使用依赖而非手写政策](../process/2026-07-26-dependencies-over-hand-rolling.md)不予采纳：陈旧锁检测、重试退避和受损处理，恰恰是应当由一个有人维护的依赖拥有的那部分工作。
+
+**在单文件上接受最后写入者胜出。** 这是最省事的实现，但当两个会话相近时间启动时，它会静默漏掉真实运行中的会话。一个会说谎的列表工具比没有列表工具更糟。
+
+**在 `dsh list-sessions` 中从会话日志读取标题。** 该方案先落地实现，随后经实机验证否决：上线的 TUI 写入 `session.jsonl.zstd`，其帧处理辅助函数是 jsonl 后端的内部实现。把它们导出，等于把某一个后端的文件格式硬编码进 CLI，而且对 SQLite 仍然什么都显示不出来。
+
+**用占位会话 id 注册 web 服务器本身。** `dsh web` 不拥有任何会话（它的会话由浏览器客户端稍后创建），因此一行服务器记录会把一个假 id 放进会话表。改为跟随会话生命周期后，浏览器会话会随打开与关闭而出现和消失，这同时也涵盖了 TUI 启动方一侧的注册，并删除了那条独立路径。
+
+**加一个 `--here`/`--workspace` 过滤开关。** 按要求放弃：列表始终是全局的，收窄范围交给用户自己的 `grep`。
+
+## 后果
+
+注册表是一项可观测性辅助设施，因此每次写入都是尽力而为：注册表故障只发出警告，绝不让正常工作的 agent 会话失败。代价是列表可能因一次失败的写入而落后于现实一步，并由下一次写入修复。
+
+标题镜像每次修订都要付出一次加锁的读-改-写，因此改名节奏激进时，每次改名都要付出这一次写入。
+
+`bootId` 只对本进程写入的记录约束 pid 复用。如果一条外来记录的 pid 已被操作系统重新分配给一个无关的存活进程，那么在其所有者移除它之前，该记录会被报告为存活——之所以接受，是因为可移植的替代方案（读取进程真实启动时间）仅在 `/proc` 上可用。
+
+存活状态只表示 pid 存在，不表示健康：挂死的进程仍会被列为正在运行。注册表刻意不对进展作出判断。
+
+## 测试
+
+单元覆盖固定了持久格式校验（截断文本、外来版本、不得遮蔽同级记录的单条损坏）、针对真正已回收 pid 的剪除、`EPERM` 算存活、按 incarnation 限定范围的注销，以及 `retitle` 的作用范围。两层并发机制各有一个回归测试，且都已验证在移除对应机制后会失败：跨进程锁用 8 个真实进程，进程内链用 24 次重叠调用。发布方在真实的 `SessionStore` 上测试，而非手搭的事件发射器，因为发布依赖该 store 实际的生命周期派发。
+
+已在 tmux 中针对组装后的应用实机验证：位于不同工作区的两个并发 TUI 会话都被列出，第一轮之后出现标题，正常退出完成注销，而 `SIGKILL` 留下的陈旧记录被下一次 `dsh list-sessions` 剪除并持久重写。

+# Agent Note: source-guard denies direct staging-checkout edits
+
+Status: implemented
+
+English | [中文](2026-07-28-source-guard-staging-edit-gate.zh.md)
+
+## Problem
+
+The [`dsh-customize`](../../../../skills/dsh-customize/SKILL.md) skill governs every personal change to a dsh source checkout: implement in a task worktree branched from the staging tip, then integrate under `.agents/merge.lock`. Its central rule is negative — do not edit the personal staging checkout directly — and a negative rule delivered only as prompt text fails in exactly the case that matters. An agent that never loads the skill never sees the rule, and one that loads it early can still forget it thirty tool calls later. The failure is silent and expensive: commits land on the staging branch that the launcher runs from, outside any task branch, with no lock held and no rollback worktree.
+
+Prompt guidance cannot fix this, because the guidance is what went unread. The rule needs an enforcement point.
+
+## Decision
+
+`@deepseek-ai/dsh-source-guard` (`packages/guard/source-guard/`) is a `tools/pre-execute` listener that returns `{kind: 'deny', reason}` for a `write` or `edit` whose target resolves inside a protected staging worktree, unless the calling session's durable log already records a successful `skill` call naming `dsh-customize`. It registers no service and contributes no prompt text or tool schema; an allowed call is indistinguishable from one made without the plugin. It is not in any shipped default composition.
+
+### Git identity from files, not a path prefix and not `git`
+
+Whether a path is protected is decided by reading `.git`, its `gitdir:` pointer, and `HEAD`. Three shapes resolve: a plain clone (`.git` is a directory that is its own common dir), a linked worktree (`.git` is a file pointing at `<common>/worktrees/<name>`, whose common dir is two levels up), and a detached HEAD (`HEAD` holds a raw object id and names no branch). A `gitdir:` pointer resolves whether absolute — what `git worktree add` writes — or relative, which git resolves against the worktree directory holding it.
+
+Denial requires the target's worktree to match the launcher's on both identities: the same shared git directory and the same branch. Both come from resolving `protectedCheckout`, so nothing about the protected branch is configured. An earlier revision matched a `dsh-staging/*` name pattern instead; the exact-branch rule replaced it because a pattern is wrong in both directions. It denied every sibling staging worktree an old install had left behind, none of which runs a launcher, and it silently protected nothing for a maintainer whose staging branch follows no naming convention — a fatal property for a shipped default that must hold for checkouts [`scripts/install.sh`](../../../../scripts/install.sh) did not create.
+
+A path-prefix rule would have been wrong, not merely imprecise. The task worktrees the skill prescribes live *inside* the protected tree at `<staging>/.worktrees/...`, so a prefix rule would deny every edit the workflow requires. Resolution walks outward from the target and stops at the first enclosing worktree, so it reports the innermost one: a nested task worktree answers with its own task branch and is allowed, while the launcher's own tree answers with the launcher's branch and is denied.
+
+Two path details decide whether the gate holds at all, and both are enforcement, not polish. Repository identity is compared on symlink-resolved paths (`canonicalPath` from `dsh-sandbox`), because a session cwd under `/var/...` and a configured path under `/private/var/...` are the same macOS directory and a lexical comparison would fail open on every write. And a relative `file_path` is resolved against the calling session's workspace, exactly as `dsh-tool-fs` resolves it; judging only absolute paths would have left a relative path as an unguarded route to a protected file.
+
+`protectedCheckout` names a path inside the guarded checkout, defaulting to this module's own file. That resolves the checkout the running harness was launched from — the live deployment, whatever its branch is named. A harness running from an installed copy resolves a different repository, or none, and guards nothing; the rule is meaningless outside a source checkout.
+
+The shipped TUI composition loads the plugin with these defaults, so every source install is protected without configuration. It is inert for an ordinary project: a workspace in another repository, or none, never matches the launcher's identities.
+
+### Satisfaction replayed from the durable log
+
+The gate lifts on a `tool/call` naming the `skill` tool whose arguments parse to `{name: <requiredSkill>}`, paired by call id with a non-error `tool/result`. Both fields are already durable (`packages/core/session/src/types.ts`), so this needs no new session event and no coupling to skill-provider internals.
+
+The log is the only state. In-memory satisfaction (the `WeakMap` shape [`repeat-tool-guard`](../../archived/feature/2026-07-08-repeat-tool-guard.md) uses for its chains) would be smaller, but it loses satisfaction on resume: a resumed session that already read the skill would be told to read it again, and the denial would look like a bug rather than a rule. Replay costs a scan bounded by the first hit and buys resume correctness.
+
+### Fail open, deliberately
+
+A path outside any worktree, a detached HEAD, a foreign repository, a malformed `gitdir:` pointer, and unreadable metadata all leave the call to the rest of the chain. The alternative — denying whenever git identity is unavailable — converts any `.git` permission problem into a harness that cannot write files at all. The guard exists to prevent one specific, recoverable mistake; it must not become a larger outage than the mistake.
+
+### Narrow scope
+
+`read` is never gated: inspecting staging violates nothing, and the skill explicitly permits read-only questions. `bash` is not gated either. Reliably classifying mutating shell commands is a matcher problem with no honest completion condition, so a determined model can still change staging through a shell. This is a boundary against forgetting, not a sandbox against intent.
+
+## Alternatives considered
+
+- **Advisory reminder instead of denial** (`additionalContexts` on `tools/post-execute`, the `repeat-tool-guard` shape). Rejected: the write has already happened when the reminder arrives, so the violation is committed and the guidance is again just text.
+- **`{kind: 'ask'}` routed to approval.** Rejected: it prompts on every legitimate task-worktree edit in the common case, and degrades to denial in a composition without approval support, making behavior depend on unrelated plugins.
+- **Running `git rev-parse` through `ctx.subprocess`.** Rejected after measuring the alternative: two file reads answer the same question with no process spawn per gated write, no `git` on `PATH` requirement, and no subprocess dependency. Reading `.git` and `HEAD` is a stable on-disk format, not an implementation detail.
+- **Explicit `protectedRoots` config with no detection.** Rejected: it makes the common case require configuration to be correct, and a stale absolute path silently disables protection.
+- **A configurable staging-branch name pattern** (`stagingBranchPatterns`, default `dsh-staging/*`). Shipped first, then removed: it protects the wrong set in both directions — every stale sibling worktree that runs no launcher, and nothing at all for a maintainer whose branch is named otherwise. Deriving the branch from the launcher needs no configuration and cannot be misconfigured.
+- **Auto-detecting the checkout with no override.** Rejected: the detection is a default, not a law; a deployment guarding a different checkout, or running from an installed copy, needs the explicit value.
+- **Denying everything under the checkout root, `.worktrees/` included.** Rejected: it blocks the workflow the skill prescribes, so the guard would fire on every legitimate task edit.
+- **Gating `bash` with a mutating-command matcher.** Deferred, not rejected: worth revisiting if bypasses are observed in practice. A matcher that is wrong in either direction is worse than an honestly narrow gate.
+
+## Consequences
+
+The rule now holds without depending on the model having read it, and the denial names the path, the branch, and the skill, so the model's next action is determined rather than guessed. Enforcement sits at the operation boundary that owns the decision, so it cannot be bypassed by prompt filtering or listener order.
+
+Shipping it in the TUI default means every source install is protected without configuration, and the protection follows the launcher across upgrades because the branch is derived rather than named. The cost of that reach is that the plugin loads for every user, including those whose workspace it can never match.
+
+What it cost otherwise: the guard is only as complete as its tool list, and `bash` remains open. Worktree identity is cached per directory for the plugin's lifetime, so a mid-session branch switch is not observed on either side. Only the launcher's own checkout is protected, so a stale sibling stays editable. Loading the skill lifts the gate for the whole session without verifying the workflow was actually followed — the gate proves the instructions were read, not obeyed. Satisfaction is per session, so a subagent with its own session must load the skill itself.
+
+## Testing
+
+Unit suites drive a real agent loop against a mock adapter over real git-metadata fixtures — a staging worktree, a task worktree nested inside it, a plain clone, a foreign repository on a staging-named branch, a detached HEAD, absolute and relative `gitdir:` pointers, a symlinked route to one repository, a malformed pointer, and unreadable metadata — covering both source files to per-file 100%. A companion `invariant.ts` validates the durable denial's shape, since the refusal text is the package's only model-visible output and is actionable only when it names the path, branch, and skill.
+
+The real-composition smoke boots `examples/headless-agent/tests/fixtures/guard/source-guard/cordis.yml` through the Loader and the headless app, and asserts three things about the assembled run: the tool result is an error, its text is the exact denial, and the targeted file still holds its original bytes — enforcement before dispatch, not advice after it.
+
+An ACP snapshot scenario (`source-guard-staging-deny`) originally owned the assembled transcript, seeding a staging worktree in the harness's generated cwd through a new `Scenario.prepareCwd` hook — git never tracks an entry named `.git` and `.gitignore` excludes every `worktrees/` directory, so the fixture committed the two `HEAD` bodies and the hook assembled the real layout. Authoring it paid for itself immediately: it exposed both path defects above (the transcript showed `fs-policy` answering first wherever the guard had quietly declined to judge) and then caught its own first fixture, whose ignored `worktrees/` path passed locally from an untracked file. The scenario was later removed with the assembled-run evidence consolidated into the Loader-composition smoke; the `prepareCwd` hook it introduced remains part of the snapshot harness for repository-shaped fixtures.

+# Agent Note: source-guard 拒绝直接编辑 staging 检出目录
+
+Status: implemented
+
+[English](2026-07-28-source-guard-staging-edit-gate.md) | 中文
+
+## Problem
+
+[`dsh-customize`](../../../../skills/dsh-customize/SKILL.md) skill（技能）规范对 dsh 源码检出的每项个人变更：先在从 staging 分支顶端分出的任务 worktree 中实现，再于 `.agents/merge.lock` 保护下完成集成。它的核心规则是一条禁令：不得直接编辑个人 staging 检出目录；而若只通过提示词文本传达禁令，它恰好会在最要紧的场景中失效。从未加载该 skill 的 agent（智能体）根本看不到规则；即便尽早加载，也仍可能在三十次工具调用后将其忘掉。这种失败既静默又代价高昂：提交会落在启动器实际运行的 staging 分支上，不属于任何任务分支，既未持有锁，也没有用于回滚的 worktree。
+
+提示词指导无法解决这个问题，因为未被阅读的正是这些指导。该规则需要一个强制执行点。
+
+## Decision
+
+`@deepseek-ai/dsh-source-guard`（`packages/guard/source-guard/`）是一个 `tools/pre-execute` 监听器；它会返回 `{kind: 'deny', reason}`，拒绝目标解析到受保护 staging worktree 内的 `write` 或 `edit`，除非调用会话的持久日志已经记录过一次成功的 `skill` 调用，且名称为 `dsh-customize`。它不注册服务，也不贡献提示词文本或工具 schema；获准的调用与未加载该插件时的调用没有区别。任何已交付的默认组合都不包含它。
+
+### 从文件而非路径前缀或 `git` 判定 Git 身份
+
+系统通过读取 `.git`、其中的 `gitdir:` 指针以及 `HEAD` 来判断路径是否受保护。它可以解析三种形态：普通克隆（`.git` 是目录，且自身就是共享目录）、链接 worktree（`.git` 是文件，指向 `<common>/worktrees/<name>`，其共享目录位于上两级）以及 HEAD 分离状态（`HEAD` 保存原始对象 id，不指向任何分支）。`gitdir:` 指针无论是绝对路径（`git worktree add` 写入的形式）还是相对路径都可以解析；Git 会以包含该指针的 worktree 目录为基准解析相对路径。
+
+只有目标的 worktree 在两项身份上都与启动器的 worktree 匹配时才会拒绝：共用同一个共享 Git 目录，且分支相同。这两项身份均通过解析 `protectedCheckout` 得出，因此无需配置受保护分支的任何信息。较早版本则匹配 `dsh-staging/*` 名称模式；现已改用确切分支规则，因为模式会在两个方向上出错。它会拒绝旧安装留下的每一个同级 staging worktree，尽管其中没有任何一个运行着启动器；对于 staging 分支不遵循任何命名约定的维护者，它又会静默地完全不提供保护——而已交付的默认配置必须在 [`scripts/install.sh`](../../../../scripts/install.sh) 未创建的检出目录上也能生效，这一属性是致命的。
+
+路径前缀规则不仅不精确，而且本身就是错误的。该 skill 规定的任务 worktree 位于受保护树*内部*的 `<staging>/.worktrees/...`，因此前缀规则会拒绝工作流要求的每一次编辑。解析过程从目标向外逐层查找，遇到第一个所属 worktree 时停止，因此返回最内层的 worktree：嵌套的任务 worktree 会返回自身的任务分支并获准，而启动器自身所在的树会返回启动器的分支并被拒绝。
+
+有两个路径细节决定门禁究竟能否生效，二者都是强制执行要求，而非细节润色。仓库身份会按解析符号链接后的路径进行比较（使用 `dsh-sandbox` 的 `canonicalPath`），因为位于 `/var/...` 下的会话 cwd 和位于 `/private/var/...` 下的配置路径在 macOS 上是同一个目录，若按路径字符串比较，每次写入都会故障放行（fail-open）。此外，相对 `file_path` 会完全按照 `dsh-tool-fs` 的方式，相对于调用会话的工作区解析；若只判断绝对路径，相对路径就会成为绕过门禁访问受保护文件的路径。
+
+`protectedCheckout` 指定受保护检出目录内的一条路径，默认值为本模块自身的文件。由此解析出运行中 harness 的启动来源检出目录——当前运行的部署，无论其分支采用什么名称。若 harness 从已安装副本运行，解析出的会是另一个仓库或没有仓库，因此不会保护任何内容；该规则在源码检出之外没有意义。
+
+已交付的 TUI 组合会以这些默认值加载插件，因此每个源码安装无需配置即可受到保护。对于普通项目，它不会生效：若工作区位于其他仓库中，或不存在工作区，就绝不会匹配启动器的身份。
+
+### 从持久日志回放满足状态
+
+如果日志中存在一条 `tool/call`，它调用名为 `skill` 的工具，参数可解析为 `{name: <requiredSkill>}`，且按调用 id 能配对到非错误的 `tool/result`，门禁即解除。二者都已持久化（`packages/core/session/src/types.ts`），因此无需新增会话事件，也不与 skill 提供方内部实现耦合。
+
+日志是唯一状态。在内存中记录满足状态（`WeakMap` 结构，[`repeat-tool-guard`](../../archived/feature/2026-07-08-repeat-tool-guard.md) 将其用于调用链）所需实现会更小，但恢复后满足状态会丢失：一个已经读取过该 skill 的恢复会话会被要求再次读取，而这次拒绝看起来会像缺陷而不是规则。回放的代价是扫描日志，但首次命中即停止，并换来恢复行为正确。
+
+### 刻意采用故障放行
+
+目标路径不在任何 worktree 内、HEAD 分离、属于其他仓库、`gitdir:` 指针格式错误或元数据不可读时，调用都会交给调用链的其余部分处理。反过来，只要无法判定 Git 身份就拒绝，会让任何 `.git` 权限问题都导致 harness 完全无法写文件。该 guard 旨在防止一种特定且可恢复的错误，不得造成比该错误更严重的故障。
+
+### 范围收窄
+
+`read` 从不受门禁限制：检查 staging 不会违反任何规则，而且该 skill 明确允许只读提问。`bash` 同样不受门禁限制。要可靠判定哪些 shell 命令会修改状态，需要构造一个无法给出可信完备标准的匹配器，因此执意修改的模型仍可通过 shell 修改 staging。这是一道防止遗忘的边界，不是阻止刻意操作的沙箱。
+
+## Alternatives considered
+
+- **用建议性提醒代替拒绝**（使用 `additionalContexts`，挂载在 `tools/post-execute` 上，采用 `repeat-tool-guard` 的形态）。不予采纳：提醒到达时写入已经发生，违规已成事实，而指导又一次沦为纯文本。
+- **将 `{kind: 'ask'}` 交给审批。** 不予采纳：在常见场景中，它会对任务 worktree 内每次合法编辑都发起询问；在没有审批支持的组合中还会退化为拒绝，使行为取决于无关插件。
+- **运行 `git rev-parse`，并通过 `ctx.subprocess` 执行。** 对替代方案进行实测后不予采纳：读取两个文件即可回答同一问题，每次受门禁限制的写入都无需 spawn 进程，不要求 `git` 存在于 `PATH` 中，也不依赖子进程。读取 `.git` 与 `HEAD` 所依据的是稳定的磁盘格式，而非实现细节。
+- **显式配置 `protectedRoots`，不做检测。** 不予采纳：这会让常见场景的保护效果依赖配置正确性，而陈旧的绝对路径会静默禁用保护。
+- **可配置的 staging 分支名称模式**（`stagingBranchPatterns`，默认 `dsh-staging/*`）。最初随产品交付，随后删除：它从两个方向划错了保护范围——既纳入每个不运行启动器的陈旧同级 worktree，又完全不保护分支另有名称的维护者。由启动器派生分支无需配置，也不可能配置错误。
+- **自动检测检出目录，不提供覆盖项。** 不予采纳：检测只是默认行为，而非不可更改的规定；若部署要保护另一个检出目录，或自身从已安装副本运行，就需要显式值。
+- **拒绝检出根目录下的一切操作，包括 `.worktrees/`。** 不予采纳：这会阻断该 skill 规定的工作流，让 guard 在每次合法任务编辑时触发。
+- **用修改类命令匹配器把守 `bash`。** 推迟而非否决：如果实际观察到绕过行为，值得重新考虑。任一方向判断错误的匹配器，都不如如实限定范围的门禁。
+
+## Consequences
+
+如今，该规则无需依赖模型已经读过它也能生效；拒绝理由会列出路径、分支与 skill，让模型的下一步操作明确，无需猜测。强制执行位于拥有该决策的操作边界，因此提示词过滤或监听器顺序都无法绕过它。
+
+将其纳入 TUI 默认组合意味着每个源码安装无需配置即可受到保护；由于分支是派生而非按名称指定，保护会在升级时跟随启动器。这种覆盖范围的代价是插件会为每位用户加载，包括工作区永远不可能匹配启动器身份的用户。
+
+除此之外的代价是：guard 的完整程度受限于其工具列表，`bash` 仍保持开放。worktree 身份在插件生命周期内按目录缓存，因此无法观察到任一侧在会话中途切换分支。只保护启动器自身的检出目录，因此陈旧的同级检出目录仍可编辑。加载该 skill 会为整个会话解除门禁，却不会验证工作流是否确实得到遵循——门禁只能证明指令已被阅读，不能证明已被执行。满足状态按会话隔离，因此拥有独立会话的 subagent 必须自行加载该 skill。
+
+## Testing
+
+单元测试套件基于真实 Git 元数据 fixture（测试前置数据），使用 mock 适配器驱动真实 agent loop（智能体循环）：覆盖一个 staging worktree、嵌套其中的任务 worktree、普通克隆、位于 staging 命名分支上的其他仓库、HEAD 分离状态、绝对和相对 `gitdir:` 指针、指向同一仓库的符号链接路径、格式错误的指针以及不可读元数据，使两个源码文件都达到逐文件 100% 覆盖率。配套的 `invariant.ts` 会验证持久拒绝的结构，因为拒绝文本是该包唯一面向模型的输出，且只有其中列出路径、分支和 skill 时才具有可操作性。
+
+真实组合冒烟测试通过 Loader 与 headless 应用启动 `examples/headless-agent/tests/fixtures/guard/source-guard/cordis.yml`，并对组装后的运行断言三项事实：工具结果是错误、文本与拒绝理由逐字一致、目标文件仍保留原始字节。这证明系统在分发前强制执行规则，而不是事后给出建议。
+
+一个 ACP（Agent Client Protocol）快照场景（`source-guard-staging-deny`）最初负责组装后的 transcript（文本记录），通过新的 `Scenario.prepareCwd` 钩子在 harness 生成的 cwd 中植入 staging worktree——Git 永远不会跟踪名为 `.git` 的条目，且 `.gitignore` 会排除所有 `worktrees/` 目录，因此 fixture 提交两个 `HEAD` 的内容，由钩子组装真实布局。编写它立刻证明了投入的价值：它暴露了上述两个路径缺陷（transcript 显示每当 guard 悄然不作判断时 `fs-policy` 都会率先响应），随后又发现了自身首版 fixture 的问题——被忽略的 `worktrees/` 路径因未跟踪文件而在本地通过。该场景后来被移除，组装运行证据合并进 Loader 组合冒烟测试；它引入的 `prepareCwd` 钩子仍留在快照 harness 中，服务于仓库形态的 fixture。

Every subcommand that shares no option with the default surface — `migrate`, `upgrade`, `list-sessions`, `web` — rejects a leaked `--config`/`-p`/`--resume` rather than running and dropping it. `dsh web`'s `--host`/`--port` are unvalidated pass-through overrides: the `dsh-host-webserver` schema is the single source of both the default (the shipped `cordis.yml` value when a flag is absent) and validity, and rejects a bad value at boot. `--trusted-host` appends named authorities for the /api browser-trust fence; an all-interfaces bind additionally derives the machine's LAN IP literals itself ([`src/app-cli-entry.ts`](src/app-cli-entry.ts)), so the printed LAN URL works without flags.
 
 The TUI surface:
 
 - boots the shipped default config (`examples/tui-agent/cordis.yml`), or the tree named by `--config <path>` (the demo/test escape for booting an alternate example tree), through [`dsh-app-boot`](../../packages/ui/app-boot/README.md);
-- resumes a persisted session with `dsh --resume <session-id>` and, when the Node host exposes `process.execve`, supplies the TUI's in-place handoff host: after selector preflight and current-session flush, the host disposes the app and replaces the process with a normalized `dsh --resume <id>`; runtimes without process replacement keep the displayed command fallback. The flag provides the id on the boot context under `RESUME_SESSION_ID_KEY` (no environment variable), which the shipped config reads through `!!js`, and a missing or unreadable id fails loud instead of creating a fresh session;
-- treats the **invoking directory** as the workspace — sessions, relative paths, and workspace instructions resolve from the cwd;
+- resumes a persisted session with `dsh --resume <session-id>` and, when the Node host exposes `process.execve`, supplies the TUI's in-place handoff host: after selector preflight and current-session flush, the host disposes the app and replaces the process with a normalized resume invocation; runtimes without process replacement leave the session running and say so. This CLI owns session identity and the exit line rather than the config: it mints or selects the `main` session id and provides it, plus the exact command that reproduces this invocation, on the boot context ([`MAIN_SESSION_ID_KEY`](../../packages/ui/tui/README.md) and `TUI_GOODBYE_MESSAGE_KEY`). No `cordis.yml` key can drop resume, and a missing or unreadable id fails loud instead of creating a fresh session;
+- treats the **invoking directory** as the workspace — sessions, relative paths, and workspace instructions resolve from the cwd (`dsh meta` is the sole exception, below);
 - tells the agent where its own source lives: after boot it adds a prompt section naming this harness checkout, resolved from the launcher's real path so it holds under a PATH symlink and an arbitrary cwd, so the self-referential `cordis` toolset can read and modify it;
 - applies the personal overlay from `~/.dsh` (see [app-boot's Personal config](../../packages/ui/app-boot/README.md#personal-config)): `.env` fills environment gaps (ambient > project `.env` > personal `.env`), `config.yaml` patches the booted tree.
 
+`dsh meta` is that same TUI with this harness checkout as the workspace, so working on dsh itself needs no `cd`. It chdirs to the checkout root — resolved from the launcher's real path, the same root the source-path prompt section names — after both `.env` layers are loaded, so environment precedence is unchanged while the session cwd, the `./.sessions` persistence root, and the HMR watch root all move together. It accepts only `--resume <id>`; `--config` (which would boot a foreign tree) and `-p` (which is not interactive) fail loud. Because meta sessions live under the checkout, `--resume` here sees only other meta sessions, and both the in-place handoff and the printed exit line reproduce the mode as `dsh meta --resume <id>`, so a copied command resumes the right session from any directory.
+
+`dsh migrate` and `dsh upgrade` are guided fresh-session entries over the default TUI surface: each mints a fresh session in the invoking directory and seeds its first turn with a bundled skill (`dsh-migrate` for migrating from another coding agent — opencode, pi, Claude Code, Codex; `dsh-upgrade` for upgrading this checkout), exactly as if the user typed `/skill:<name>`. 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 <id>` of the session is an ordinary TUI session with no re-injection.
+
+`dsh list-sessions` lists the sessions running right now: session id, pid, uptime, workspace, and title, newest first. It is read-only and boots no agent tree — it mounts the [session registry](../../packages/session-registry/session-registry/README.md) alone, so listing is fast and cannot start model work as a side effect. Every surface publishes its sessions into that registry through [`dsh-session-registry-live`](../../packages/session-registry/session-registry-live/README.md), and records whose process is gone are pruned on read, so a crashed session disappears without cleanup. `--json` emits the same records as a machine-readable array; an empty listing prints one line and exits 0. There is no workspace filter: the listing is always every live session, whatever directory it runs in. Only top-level surfaces appear — subagents share or spawn other processes and are deliberately invisible.
+
 The Web and headless surfaces boot one shared composition (`cordis.yml`): both treat the invoking directory as the default project and Workspace root, create named Workspaces beneath that root unless `--workspace-root <path>` overrides it, load applicable `AGENTS.md`/`CLAUDE.md` instructions into each agent-loop request prefix with a 65,536-byte render budget, and opt into first-message model titles. 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.

+`dsh migrate` 与 `dsh upgrade` 是默认 TUI 界面之上的引导式全新会话入口：各自在调用目录中创建一个全新会话，并以一个内置 skill 播种其首轮（`dsh-migrate` 用于从其他编码 agent 迁移——opencode、pi、Claude Code、Codex；`dsh-upgrade` 用于升级本 checkout），效果等同于用户手动键入 `/skill:<name>`。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 <id>` 恢复该会话时是普通 TUI 会话，不会重复注入。
+
+`dsh list-sessions` 列出此刻正在运行的会话：会话 id、pid、运行时长、工作区和标题，最新的在前。它是只读的，不启动任何 agent 树——它只挂载[会话注册表](../../packages/session-registry/session-registry/README.md)，因此列表既快，也不会作为副作用启动模型工作。每个界面都通过 [`dsh-session-registry-live`](../../packages/session-registry/session-registry-live/README.md) 把自己的会话发布到该注册表，进程已不存在的记录会在读取时被剪除，因此崩溃的会话无需清理便会消失。`--json` 以机器可读的数组形式输出同样的记录；空列表打印一行并以 0 退出。没有工作区过滤：列表始终是全部存活会话，无论它们运行在哪个目录下。只有顶层界面会出现——subagent 共用别的进程，或 spawn 出别的进程，因此被刻意排除在列表之外。
+
 Web 和无头界面启动同一个共享组合（`cordis.yml`）：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 <path>` 覆盖，否则会在该根目录下创建具名 Workspace；它们会把适用的 `AGENTS.md`/`CLAUDE.md` 指令加载到每个 agent-loop 请求前缀中，渲染预算为 65,536 字节，并选用首条消息模型标题。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`。

+`/resume` opens a searchable keyboard selector with titles, activity, last-turn results, model route, durable goal phase, and live/persisted state. The installed `dsh` host flushes and disposes the current app, then replaces the process with `dsh --resume <id>`; a host that cannot hand off in place says so and leaves the session running. Resume needs no key in this file: `dsh` provides the session identity and the exit line on the boot context, so `--resume <id>` and the printed resume command survive any personal-overlay patch of the `tui-agent` entry. With no flag the agent starts a new session. A missing or unreadable id starts no agent and emits `agent-loop/config-start-failed`: the TUI prints the failure and exits nonzero.

+
+Opt-in durable context naming the tmux session, window, and pane this agent process runs in, plus the window's pane-tree layout. Sampled once per turn during model-request preparation. `dsh-agent-spine-demo` and shipped examples do not mount it. Decision record: [the tmux-context Agent Note](../../../.agents/notes/implemented/feature/2026-07-27-tmux-location-context.md).
+
+## Config
+
+```yaml
+- id: tmux-context
+  name: '@deepseek-ai/dsh-tmux-context'
+  config:
+    refreshIntervalMs: 60000 # optional; omit or set to 0 to inject on every changed turn
+```
+
+`refreshIntervalMs` must be a non-negative safe integer. Omission or `0` injects whenever the tmux state changed since the last injection. A positive value additionally suppresses injections that fall within that many milliseconds of the latest one.
+
+## How it reads tmux
+
+The plugin prepends an `agent/step` listener that runs only on the first step of each turn. When due, it runs one read-only command through the `ctx.bash` executor seam:
+
+```sh
+[ -n "$TMUX_PANE" ] || exit 1
+self_tty=$(ps -o tty= -p <pid> | tr -d ' ')
+pane_tty=$(tmux display-message -t "$TMUX_PANE" -p '#{pane_tty}') || exit 1
+[ "$pane_tty" = "/dev/$self_tty" ] || exit 1
+exec tmux display-message -t "$TMUX_PANE" -p '<format>'
+```
+
+`$TMUX_PANE` alone is insufficient: a terminal launched from a tmux shell (a VS Code integrated terminal, a desktop launcher) **inherits** `$TMUX` and `$TMUX_PANE` from that ancestor, so the variables are present even though the process does not live in that pane. The command therefore also compares the pane's `#{pane_tty}` against this process's own controlling terminal (`ps -o tty=` for its pid): a genuine pane owns this process's tty, while an inherited environment names some other pane's tty. Running through `ctx.bash` applies the deployment's sandbox and policy; the plugin owns no subprocess code. When `ctx.bash` is absent, the process is not in a real tmux pane (`$TMUX_PANE` unset, or the tty does not match ⇒ nonzero exit), or the reading is malformed, the attempt is a no-op, never an error.
+
+State is pulled on every eligible turn — a moved, renamed, or re-laid-out pane is picked up without any tmux hook or background process. The plugin re-injects only when the rendered tmux state differs from its last injection, so an unchanged location adds nothing.
+
+## Timing semantics
+
+When an injection is due, the plugin appends one injected `user/message` through `agent.inject()` before `step/start`, with source `{ kind: 'plugin', plugin: 'tmux-context' }`. Change suppression and interval scheduling scan the raw durable session events for the latest injection of this source, so the schedule survives compaction and resumed processes without process-local cache state; sessions schedule independently. The reading records a request-preparation attempt, not a committed step; because the listener runs first, its append may remain when a later pre-step listener cancels or fails the attempt (the log is append-only and the plugin performs no rollback).
+
+## Model Experience
+
+### Preparation-time tmux location
+
+#### What the model sees
+
+On each turn whose tmux state changed, one source-tagged context message with the three lines below. `<window-layout>` is tmux's compact pane-tree description; pane and window pixel sizes are intentionally excluded, and the contents of sibling panes are never captured.
+
+##### Changed-turn reading
+
+```markdown
+tmux location (turn <turn>):
+session <session>, window <index> "<name>", pane <index> <pane-id>
+window active=<0|1>, pane active=<0|1>, layout <window-layout>
+```
+
+#### Token effect
+
+Each two-line reading accumulates until compaction shadows it. Unchanged locations and interval suppression add nothing.
+
+#### KV Cache effect
+
+Append-only; newly visible content follows the reusable request prefix and does not invalidate existing KV-cache entries.
+
+## Known Limitations and Deferred Work
+
+- **First step only** — a pane moved or resized mid-turn is reflected on the next turn, not between steps.
+- **Own location only** — the plugin never captures the visible text of sibling panes.
+- **Layout, not size** — pane/window pixel dimensions are omitted; only the layout tree and active flags are reported.
+- **Tab-delimited fields** — a tmux window name containing the literal two-character sequence `\t` would mis-split the reading and be skipped as malformed; ordinary names are unaffected.
+- **tty-based pane detection** — the process is considered "in tmux" only when its controlling terminal matches `$TMUX_PANE`'s `#{pane_tty}`. This deliberately excludes terminals that inherited `$TMUX`/`$TMUX_PANE` from a tmux ancestor (e.g. a VS Code integrated terminal). `ps -o tty=` is POSIX; the check is a no-op wherever it or `#{pane_tty}` is unavailable.

+
+可选启用的持久上下文，记录本 agent 进程所在的 tmux session、window、pane，以及该 window 的 pane 树布局。在准备模型请求时每轮采样一次。`dsh-agent-spine-demo` 与随附示例均不挂载它。决策记录见：[tmux-context Agent Note](../../../.agents/notes/implemented/feature/2026-07-27-tmux-location-context.md)。
+
+## 配置
+
+```yaml
+- id: tmux-context
+  name: '@deepseek-ai/dsh-tmux-context'
+  config:
+    refreshIntervalMs: 60000 # optional; omit or set to 0 to inject on every changed turn
+```
+
+`refreshIntervalMs` 必须是非负安全整数。省略或 `0` 表示只要 tmux 状态自上次注入以来发生变化就注入。正值会额外抑制距最近一次注入不足该毫秒数的注入。
+
+## 如何读取 tmux
+
+插件前置注册一个 `agent/step` 监听器，仅在每轮的第一个 step 运行。当需要注入时，它通过 `ctx.bash` 执行器 seam 运行一条只读命令：
+
+```sh
+[ -n "$TMUX_PANE" ] || exit 1
+self_tty=$(ps -o tty= -p <pid> | tr -d ' ')
+pane_tty=$(tmux display-message -t "$TMUX_PANE" -p '#{pane_tty}') || exit 1
+[ "$pane_tty" = "/dev/$self_tty" ] || exit 1
+exec tmux display-message -t "$TMUX_PANE" -p '<format>'
+```
+
+仅凭 `$TMUX_PANE` 并不足够：从 tmux shell 启动的终端（VS Code 集成终端、桌面启动器）会从该祖先进程**继承** `$TMUX` 与 `$TMUX_PANE`，因此即使进程并不位于那个 pane 中，这些变量依然存在。为此该命令还会把 pane 的 `#{pane_tty}` 与本进程自己的控制终端（对其 pid 执行 `ps -o tty=`）作比较：真正的 pane 拥有本进程的 tty，而继承而来的环境指向的是另一个 pane 的 tty。通过 `ctx.bash` 运行会应用部署方的沙箱与策略；插件不拥有任何子进程代码。当 `ctx.bash` 缺失、进程不在真实的 tmux pane 内（`$TMUX_PANE` 未设置，或 tty 不匹配 ⇒ 非零退出）或读取结果格式非法时，本次尝试为空操作，绝不报错。
+
+状态在每个符合条件的轮次拉取——pane 被移动、改名或重新布局都会被感知，无需任何 tmux hook 或后台进程。插件仅在渲染出的 tmux 状态与上次注入不同时才重新注入，因此位置不变时不会新增任何内容。
+
+## 时序语义
+
+当需要注入时，插件在 `step/start` 之前通过 `agent.inject()` 追加一条注入的 `user/message`，来源为 `{ kind: 'plugin', plugin: 'tmux-context' }`。变化抑制与间隔调度会扫描原始持久会话事件中该来源的最近一次注入，因此调度可跨压缩与恢复的进程存续，无需进程内缓存状态；各会话独立调度。该读数记录的是一次请求准备尝试，而非已提交的 step；由于监听器最先运行，当后续 pre-step 监听器取消或失败时，它的追加可能仍会保留（日志只追加，插件不做回滚）。
+
+## 模型体验
+
+### 准备期 tmux 位置
+
+#### 模型看到的内容
+
+在 tmux 状态发生变化的每一轮，注入一条带来源标记、含以下三行的上下文消息。`<window-layout>` 是 tmux 紧凑的 pane 树描述；pane 与 window 的像素尺寸有意省略，相邻 pane 的内容从不采集。
+
+##### 变化轮次读数
+
+```markdown
+tmux location (turn <turn>):
+session <session>, window <index> "<name>", pane <index> <pane-id>
+window active=<0|1>, pane active=<0|1>, layout <window-layout>
+```
+
+#### Token 影响
+
+每条两行读数会累积，直到压缩将其遮蔽。位置未变化以及间隔抑制不会新增内容。
+
+#### KV 缓存影响
+
+只追加；新增可见内容位于可复用的请求前缀之后，不会使已有 KV 缓存条目失效。
+
+## 已知限制与后续工作
+
+- **仅第一个 step**——轮次中途移动或缩放的 pane 会在下一轮反映，而非在 step 之间。
+- **仅自身位置**——插件从不采集相邻 pane 的可见文本。
+- **只有布局，没有尺寸**——省略 pane/window 像素尺寸；仅报告布局树与活动标志。
+- **制表符分隔字段**——若 tmux window 名称包含字面两字符序列 `\t`，会使读数分割错误并作为非法读数跳过；常规名称不受影响。
+- **基于 tty 的 pane 判定**——只有当进程的控制终端与 `$TMUX_PANE` 的 `#{pane_tty}` 一致时，才视为“位于 tmux 中”。这会有意排除从 tmux 祖先进程继承 `$TMUX`／`$TMUX_PANE` 的终端（如 VS Code 集成终端）。`ps -o tty=` 属于 POSIX；在其或 `#{pane_tty}` 不可用的环境中，该检查即为空操作。

The app composes persistence and session query for `/resume`; an embedding host may additionally provide `tuiResumeHost` for in-place process handoff.
+Session identity is launcher-owned rather than configurable: a launcher provides `MAIN_SESSION_ID_KEY` on the boot context, and this app binds both the TUI and the configured agent to that id, loading persisted history only when the launcher also set `resume`. With no such slot the app mints a `main-session-<uuid>` and creates it fresh. The TUI mounts before the spine so it can render a matching config-start failure instead of leaving a blank terminal. The app composes persistence and session query for `/resume`; a launcher may additionally provide `tuiResumeHost` for in-place process handoff and `TUI_GOODBYE_MESSAGE_KEY` for the line printed on exit.
+
+`persistenceRoot` defaults to project-local `./.sessions`: an app bundle must not assume the user's shared session store. A launcher that wants one store across every cwd states that policy through the `SESSIONS_ROOT_KEY` boot slot (`ctx.provide` before any Loader entry mounts) — the dsh CLI provides its Harness-home root there, so its `/resume` lists sessions from every workspace. Precedence is explicit config, then the launcher slot, then the project-local default.

+
+English | [中文](README.zh.md)
+
+An enforcement gate, not a model-facing tool: it never appears in the tool list and adds exactly one behavior — it denies a `write` or `edit` whose target sits inside the dsh checkout the running harness was launched from, on that checkout's own branch, until the calling session's durable log shows a successful load of the `dsh-customize` skill. That skill requires personal changes to be implemented in a task worktree and integrated under the staging lock; this plugin turns its central rule ("do not edit the personal staging checkout directly") from prompt guidance into a boundary the model cannot cross by forgetting.
+
+## Config
+
+```yaml
+- id: source-guard
+  name: '@deepseek-ai/dsh-source-guard'
+  config:
+    requiredSkill: dsh-customize          # default; the skill whose load lifts the denial
+    tools: [write, edit]                  # default; the gated tool names
+    protectedCheckout: /path/to/checkout  # defaults to this module's own location
+```
+
+Every field fails loud at plugin load: an empty `tools` list, a blank `requiredSkill`, or a relative `protectedCheckout` throws, never a silent fall-back.
+
+`protectedCheckout` names a path inside the checkout to guard, and its worktree supplies BOTH protected identities: the repository and the exact branch. Its default is this module's own file, which resolves the checkout the running harness was launched from — the live deployment, whatever its branch is named. Nothing about the branch is configured or pattern-matched, so a maintainer whose staging branch follows no naming convention is protected identically. A harness running from an installed copy resolves a different repository, or none, and therefore guards nothing; the rule is meaningless outside a source checkout.
+
+The shipped TUI composition (`examples/tui-agent/cordis.yml`) loads this plugin with defaults. It is inert for anyone whose workspace is not the launcher's own checkout, so an ordinary project sees no change.
+
+## Which paths are protected
+
+Protection is decided by git identity read from files — `.git`, its `gitdir:` pointer, and `HEAD` — never by path prefix and never by running `git`. Prefix matching would be wrong here: the task worktrees the skill prescribes live *inside* the staging tree, at `<staging>/.worktrees/...`, and are exactly where edits belong.
+
+Resolution walks OUTWARD from the target and stops at the first enclosing worktree, so it reports the INNERMOST one. Denial needs that worktree to match the launcher's on BOTH identities: the same shared git directory and the same branch. A task worktree nested under the protected tree answers with its own task branch and passes; the launcher's own tree answers with the launcher's branch and is denied. Repository identity is compared on symlink-resolved paths, so two routes to one repository — a session cwd under `/var/...` and a configured path under `/private/var/...` on macOS — match rather than falling open.
+
+Requiring the exact branch, not a name pattern, keeps the gate on the live deployment only. A stale sibling checkout left by an earlier install shares the repository but runs no launcher, so the workflow rule does not apply to it and it stays editable.
+
+A `gitdir:` pointer may be absolute (what `git worktree add` writes) or relative, which git resolves against the worktree directory holding it; both resolve here. A relative `file_path` resolves against the calling session's workspace, exactly as the filesystem tools resolve it, so it is not an unguarded route to a protected file.
+
+The gate is deliberately narrow:
+
+- **`read` is never gated.** Inspecting the staging checkout violates nothing, so only mutating tools are candidates.
+- **`bash` is not gated.** Reliably classifying mutating shell commands is out of scope, so a determined model can still change staging through a shell.
+- **Calls without an agent are allowed.** A direct `ctx.tools.execute()` caller has no session to replay and no model to correct.
+- **Unresolvable git state fails OPEN.** A path outside any worktree, a detached HEAD on either side, a different repository or branch, a malformed `.git` pointer, or unreadable metadata all leave the call to the rest of the chain. A gate that blocked every write whenever git identity was unavailable would cause more harm than the violation it prevents.
+- **An unresolvable target is not judged.** An empty `file_path`, a non-string one, or a relative one in a session that names no workspace leaves the call to the tool's own validation.
+
+Worktree identity is cached per target directory for the plugin's lifetime, so repeated writes in one directory read git metadata once; a mid-session branch switch is therefore not observed.
+
+## How the denial lifts
+
+Satisfaction is replayed from the session's durable log: a `tool/call` naming the `skill` tool whose arguments parse to `{name: <requiredSkill>}`, paired by call id with a non-error `tool/result`. Because the log is the only state, satisfaction survives a session resume — a resumed session that already loaded the skill is not asked again. A failed load, a differently-named skill, and malformed argument JSON all leave the denial in place.
+
+Satisfaction is per session, so a subagent with its own session must load the skill itself.
+
+## Enforcement point
+
+The gate is a `tools/pre-execute` listener returning `{kind: 'deny', reason}`, so the call never dispatches and the file is never touched. It delegates via `next()` in every non-violating case. Denial — not an advisory reminder — is the point: an advisory nudge leaves the violation committed, and `ask` degrades to denial in a composition without approval support.
+
+## Testing
+
+Unit suites drive a real agent loop against a mock adapter over real git-metadata fixtures — a staging worktree, a task worktree nested inside it, a plain clone, a foreign repository on a staging-named branch, a detached HEAD, absolute and relative `gitdir:` pointers, a symlinked route to the same repository, and unreadable metadata — to per-file 100%. The assembled-run evidence is the Loader-composition smoke (`tests/loader-composition.e2e.ts`): it boots a real headless app over `examples/headless-agent/tests/fixtures/guard/source-guard/cordis.yml`, seeds a staging worktree in a temporary cwd, and asserts the tool result is an error carrying the exact denial while the targeted file keeps its original bytes.
+
+## Model Experience
+
+### Denied filesystem call
+
+#### What the model sees
+
+A gated call into a protected worktree without the required skill loaded returns an error result carrying exactly the text below. No prompt section, tool schema, or successful-call text is added, and an allowed call is indistinguishable from one made without this plugin.
+
+##### Denial result
+
+```markdown
+Error: Editing "<path>" directly is not allowed: it is inside the dsh checkout this session is running from, on branch <branch>. Load the <requiredSkill> skill first and follow it — implement in a task worktree, then integrate under the staging lock.
+```
+
+#### Token effect
+
+Zero tokens while no denial occurs. A denial adds its small retained error result and avoids the success payload the call would have produced.
+
+#### KV Cache effect
+
+Append-only; newly visible content follows the reusable request prefix and does not invalidate existing KV-cache entries.
+
+## Known Limitations and Deferred Work
+
+- **`bash` is ungated** — the guard is a boundary for the filesystem tools only; a shell command can still mutate a protected worktree.
+- **Worktree identity is cached per directory for the plugin's lifetime** — switching a protected worktree's branch mid-session does not change decisions until the next load, on either the target or the launcher side.
+- **Only the launcher's own checkout is protected** — a stale sibling checkout of the same repository stays editable, deliberately; run `dsh` from it to protect it.
+- **Disarmed outside a source checkout** — a harness running from an installed copy protects nothing unless `protectedCheckout` names a real checkout explicitly.
+- **Satisfaction is per session** — a subagent's session must load the skill itself; a parent's load does not carry over.
+- **Fail-open on unresolvable git state** — a broken or unreadable `.git` means no protection, chosen deliberately over blocking every edit.
+- **One skill lifts the whole gate for the session** — loading it does not verify the workflow was actually followed, only that the instructions were read.

+
+[English](README.md) | 中文
+
+这是一道强制执行门禁，而非面向模型的工具：它不会出现在工具列表中，只增加一种行为。若 `write` 或 `edit` 的目标位于运行中 harness 启动来源的 dsh 检出目录内，并处于该检出目录自身的分支上，它会拒绝调用，直到调用方会话的持久日志表明已成功加载 `dsh-customize` skill（技能）。该 skill 要求在任务 worktree 中实现个人变更，并在 staging 锁保护下完成集成；本插件把其核心规则（「不要直接编辑个人 staging 检出目录」）从提示词指导变成一道模型无法因遗忘而越过的边界。
+
+## 配置
+
+```yaml
+- id: source-guard
+  name: '@deepseek-ai/dsh-source-guard'
+  config:
+    requiredSkill: dsh-customize          # default; the skill whose load lifts the denial
+    tools: [write, edit]                  # default; the gated tool names
+    protectedCheckout: /path/to/checkout  # defaults to this module's own location
+```
+
+插件加载时，每个字段都会对错误配置快速失败：`tools` 为空列表、`requiredSkill` 为空白字符串，或 `protectedCheckout` 使用相对路径时，都会抛出错误，绝不静默回退。
+
+`protectedCheckout` 指定位于待保护检出目录内的一条路径；其 worktree 会提供两项受保护身份：仓库和确切分支。其默认值是本模块自己的文件，由此解析出运行中 harness 启动来源的检出目录——当前运行的部署，无论其分支采用什么名称。分支既无需配置，也不会通过模式匹配，因此 staging 分支不遵循任何命名约定的维护者同样会受到保护。若 harness 从已安装副本运行，则会解析到另一个仓库，或根本解析不到仓库，因此不会保护任何内容；这条规则在源码检出目录之外没有意义。
+
+已交付的 TUI 组合（`examples/tui-agent/cordis.yml`）会以默认配置加载本插件。若用户的工作区并非启动器自身所在的检出目录，本插件不会生效，因此普通项目不会发生任何变化。
+
+## 受保护的路径
+
+保护范围根据从文件读取的 Git 身份确定，即 `.git`、其中的 `gitdir:` 指针和 `HEAD`；既不按路径前缀判断，也不运行 `git`。此处若匹配路径前缀就会出错：skill 要求使用的任务 worktree 位于 staging 树*内部*的 `<staging>/.worktrees/...`，而这正是应该进行编辑的位置。
+
+解析过程从目标路径开始向外逐层查找，遇到第一个所属 worktree 就停止，因此返回最内层的 worktree。只有该 worktree 在两项身份上都与启动器的 worktree 匹配，才会拒绝：共用同一个共享 Git 目录，且分支相同。嵌套在受保护树下的任务 worktree 会返回自己的任务分支并获准；启动器自身所在的树会返回启动器的分支并被拒绝。仓库身份会按解析符号链接后的路径进行比较，因此指向同一仓库的两条路径——macOS 上位于 `/var/...` 下的会话 cwd 和位于 `/private/var/...` 下的配置路径——会相互匹配，而不会触发故障放行（fail-open）。
+
+要求匹配确切分支而非名称模式，可确保门禁仅作用于当前运行的部署。先前安装留下的陈旧同级检出目录虽然共享仓库，却没有运行启动器，因此该工作流规则不适用于它，它仍可编辑。
+
+`gitdir:` 指针既可以是绝对路径（`git worktree add` 写入的形式），也可以是相对路径；Git 会以包含该指针的 worktree 目录为基准解析相对路径，本插件对两者都能解析。相对 `file_path` 会像文件系统工具一样，相对于调用会话的工作区解析，因此不会成为绕过门禁访问受保护文件的路径。
+
+门禁刻意保持较窄的范围：
+
+- **`read` 从不受门禁限制。** 检查 staging 检出不构成违规，因此只有修改类工具是候选项。
+- **`bash` 不受门禁限制。** 可靠识别会修改内容的 shell 命令不在范围内，因此执意修改的模型仍可通过 shell 修改 staging。
+- **没有 agent（智能体）的调用会被放行。** 直接调用 `ctx.tools.execute()` 的调用方没有可供回放的会话，也没有需要纠正的模型。
+- **无法解析 Git 状态时故障放行。** 不属于任何 worktree 的路径、任一侧的 HEAD 分离状态、其他仓库或分支、格式错误的 `.git` 指针或不可读的元数据，都会把调用交给链中后续环节处理。若每逢 Git 身份不可用就阻止所有写入，这道门禁造成的危害将大于它所防止的违规。
+- **无法解析的目标不会被判断。** `file_path` 为空、不是字符串，或它是相对路径而会话未指定工作区时，调用会交给工具自身校验。
+
+插件会在其整个生命周期内按目标目录缓存 worktree 身份，因此同一目录中的重复写入只读取一次 Git 元数据；由此，系统不会观察到会话中途的分支切换。
+
+## 如何解除拒绝
+
+是否满足解锁条件由会话的持久日志回放得出：日志中存在一条 `tool/call`，它调用名为 `skill` 的工具，参数可解析为 `{name: <requiredSkill>}`，并且有一条调用 id 相同的非错误 `tool/result` 与之配对。由于日志是唯一状态源，恢复会话时仍能保留这一结果：若恢复的会话已经加载该 skill，系统不会再次要求加载。加载失败、skill 名称不同或参数 JSON 格式错误，都会让拒绝继续生效。
+
+解锁条件按会话独立满足，因此拥有独立会话的 subagent 必须自行加载该 skill。
+
+## 强制执行点
+
+门禁是一个 `tools/pre-execute` 监听器，返回 `{kind: 'deny', reason}`，因此调用绝不会分派执行，文件也绝不会被修改。在所有不违规的情况下，它都会通过 `next()` 委派。这里刻意采用拒绝而非建议性提醒：建议性提醒仍会让违规落地，而在不支持批准的组合中，`ask` 会退化为拒绝。
+
+## 测试
+
+单元测试套件基于真实 Git 元数据 fixture（测试前置数据），使用 mock 适配器驱动真实 agent loop（智能体循环）：覆盖 staging worktree、嵌套其中的任务 worktree、普通克隆、位于 staging 命名分支上的其他仓库、HEAD 分离状态、绝对和相对 `gitdir:` 指针、指向同一仓库的符号链接路径以及不可读元数据，达到逐文件 100% 覆盖率。组装运行层面的证据来自 Loader 组合冒烟测试（`tests/loader-composition.e2e.ts`）：它通过 `examples/headless-agent/tests/fixtures/guard/source-guard/cordis.yml` 启动一个真实的 headless 应用，在临时 cwd 中植入 staging worktree，并断言工具结果是携带精确拒绝文本的错误，同时目标文件保持原始字节不变。
+
+## 模型体验
+
+### 被拒绝的文件系统调用
+
+#### 模型看到的内容
+
+如果未加载必需 skill 就对受保护 worktree 发起受门禁限制的调用，系统会返回错误结果，其中的文本与下文完全一致。系统不会添加提示词段、工具 schema 或成功调用文本；允许的调用与未启用此插件时的调用完全无法区分。
+
+##### 拒绝结果
+
+```markdown
+Error: Editing "<path>" directly is not allowed: it is inside the dsh checkout this session is running from, on branch <branch>. Load the <requiredSkill> skill first and follow it — implement in a task worktree, then integrate under the staging lock.
+```
+
+#### Token 影响
+
+未发生拒绝时为零 token。一次拒绝会添加一条会保留在历史中的短小错误结果，同时避免生成该调用原本会产生的成功载荷。
+
+#### KV Cache 影响
+
+仅追加；新出现的内容位于可复用请求前缀之后，不会使现有 KV-cache 条目失效。
+
+## 已知限制与暂缓工作
+
+- **`bash` 不受门禁限制**：此插件只为文件系统工具提供边界；shell 命令仍可修改受保护的 worktree。
+- **插件生命周期内按目录缓存 worktree 身份**：在会话中途切换受保护 worktree 的分支，不会改变判断结果，直至下次加载插件；目标侧和启动器侧都是如此。
+- **仅保护启动器自身的检出目录**：同一仓库中的陈旧同级检出目录会被刻意保留为可编辑状态；若要保护它，请从中运行 `dsh`。
+- **源码检出之外不启用**：从已安装副本运行的 harness 不保护任何内容，除非 `protectedCheckout` 明确指定真实检出目录。
+- **解锁条件按会话独立满足**：subagent 的会话必须自行加载该 skill；父会话的加载状态不会继承。
+- **无法解析 Git 状态时故障放行**：损坏或不可读的 `.git` 会使保护失效；这是刻意选择的结果，因为另一方案是阻止所有编辑。
+- **仅加载一个 skill 即可为会话解除整道门禁**：加载该 skill 并不能验证是否实际遵循工作流，只能证明已阅读这些指令。

+# session-registry/ — live-session registry family
+
+English | [中文](README.zh.md)
+
+Which sessions are running right now, readable from a different process. `dsh list-sessions` is the consumer.
+
+| Package | Role | ctx key |
+|---|---|---|
+| [`session-registry/`](session-registry/README.md) | The seam: abstract registry service contract and record vocabulary | `ctx.sessionRegistry` |
+| [`session-registry-file/`](session-registry-file/README.md) | Backend: one lock-guarded JSON file, pid-derived liveness | — |
+| [`session-registry-live/`](session-registry-live/README.md) | Publisher: follows session lifecycle and title events, keeping the registry in step | — |
+
+The split follows the three-package capability-seam convention: the seam answers "what is live" for a short-lived reader that mounts nothing else, the file backend owns today's medium and can be replaced by a database without touching consumers, and the publisher needs the session store and runs inside a full agent composition. Liveness is derived from the recorded pid at read time rather than stored, so a killed process leaves nothing to clean up. Records carry their own title because log location, format, and compression are per-deployment backend choices an independent reader cannot portably parse.
+
+This family is independent of session persistence: it records which processes hold which sessions, never conversation content, and a session that is never persisted still lists.

+# session-registry/：活跃会话注册表家族
+

+| 包 | 职责 | ctx 键 |

+| [`session-registry-live/`](session-registry-live/README.md) | 发布方：跟随会话生命周期与标题事件，让注册表保持同步 | — |
+
+这样拆分遵循由三个包构成的能力 seam 惯例：seam 要回答「哪些会话是活跃的」，供一个不挂载其他任何东西的短生命周期读取方使用；文件后端拥有今天的介质，将来可以换成数据库而不触及消费方；发布方需要会话存储，运行在完整的 agent（智能体）组合体内。存活状态在读取时由记录的 pid 推导，而不是存下来，因此进程被杀掉后不留下任何需要清理的东西。记录自带标题，因为日志位置、格式和压缩都是各部署自行选择的后端方案，独立的读取方无法以可移植的方式解析。
+
+这个家族与会话持久化相互独立：它只记录哪些进程持有哪些会话，绝不记录对话内容；从未被持久化的会话同样能被列出。

+Liveness is derived at read time from the recorded pid via `kill(pid, 0)`: `ESRCH` is dead, `EPERM` is alive under another user, and any other errno propagates rather than being read as an answer. A process killed without running its disposer therefore leaves a record that the next `list()` prunes and rewrites — no daemon, no heartbeat, and no permanent phantom. `bootId` distinguishes a recycled pid, so deregistration cannot delete a namesake record belonging to a different incarnation.
+
+## Concurrency
+
+Both layers are required and neither substitutes for the other.
+
+- **Across processes**, each read-modify-write cycle holds a [`proper-lockfile`](https://github.com/moxystudio/node-proper-lockfile) advisory lock. Unlocked whole-file republication loses records under concurrent launchers, which is why the storage-hub JSON backend — documented last-write-wins, single-host-process — cannot serve this medium.
+- **Within one process**, calls queue on an internal chain. The advisory lock is tracked per process, so overlapping same-process callers contend for its bounded retry budget instead of queueing; past roughly a dozen concurrent calls that budget runs out and a registration rejects. Callers publish fire-and-forget, so such a rejection would silently drop a live session from the listing.
+
+Writes are temp-file plus atomic `rename` (no fsync: a listing lost to a crash is rebuilt by the next process's read, so crash durability buys nothing here), under a `0o700` root with a `0o600` file.
+
+## Durable format
+
+`sessions.json` carries a `version` stamp pinned at `0` under the pre-release stance: a differing version is rejected rather than migrated. Reads validate every field because the medium is shared and user-visible. An individually unusable row is dropped while its siblings survive, and unparsable text or a foreign version reads as empty — one malformed record written by another harness version must not hide every other live session. Any of these marks the medium damaged, so the next write republishes and heals it.
+
+## Config
+
+| Key | Type | Default | Meaning |
+| --- | --- | --- | --- |
+| `root` | string | required — no default (a cwd fallback would scatter registries) | Directory holding `sessions.json`; created `0o700` on demand |
+| `lockStaleMs` | natural | `10000` | Milliseconds after which a held lock is treated as abandoned and reclaimed |
+| `lockRetries` | natural | `10` | Retries before a contended acquisition fails loud |
+
+## Model Experience
+
+None, as this package registers no tools, injects no prompts, and appends no session events; it stores host-side process records for the CLI listing surface only.
+
+#### KV Cache effect
+
+Independent of live requests: the registry never touches a request prefix, so nothing here can invalidate provider cache reuse.
+
+## Known Limitations and Deferred Work
+
+- **A reused pid within the stale window is trusted** — `bootId` distinguishes incarnations of records this process wrote, but a foreign record whose pid the operating system has since reassigned to an unrelated live process is reported alive until its owner removes it.

+
+[English](README.md) | 中文
+
+[存活会话注册表 seam](../session-registry/README.md) 的文件后端实现：整套介质就是 Harness home 下的一个加锁保护的 JSON 文件。挂载它即发布 `ctx.sessionRegistry`；`file` 暴露注册表文件的绝对路径（`<root>/sessions.json`）。
+
+## 存活状态与崩溃安全
+
+存活状态在读取时由记录的 pid 经 `kill(pid, 0)` 推导：`ESRCH` 表示已消亡，`EPERM` 表示存活于另一个用户之下，其他任何 errno 都向外抛出，而不会被当成一个答案来解读。因此，未运行 disposer 就被杀掉的进程留下的记录，会被下一次 `list()` 剪除并重写——不需要 daemon，不需要心跳，也不会有永久残留的幽灵记录。`bootId` 用于区分被复用的 pid，因此注销不会删除属于另一个 incarnation 的同名记录。
+
+## 并发
+
+两层机制都是必需的，任何一层都无法替代另一层。
+
+- **跨进程**：每个读改写周期都持有 [`proper-lockfile`](https://github.com/moxystudio/node-proper-lockfile) 咨询锁。无锁的全文件重发布会在并发启动器下丢失记录，这正是 storage-hub JSON 后端（文档声明 last-write-wins、单宿主进程）无法承担该介质的原因。
+- **进程内**：调用在内部链上排队。咨询锁按进程跟踪，因此同进程的重叠调用者会争用其有限的重试预算而非排队；并发调用超过十来个时预算耗尽，注册会被拒绝。调用方以 fire-and-forget 方式发布，这样的拒绝会静默地把一个存活会话从列表中丢掉。
+
+写入采用临时文件加原子 `rename`（不做 fsync：崩溃丢失的列表会被下一个进程的读取重建，崩溃持久性在这里没有收益），根目录 `0o700`，文件 `0o600`。
+
+## 持久化格式
+
+`sessions.json` 携带一个 `version` 戳，在预发布立场下固定为 `0`：版本不同将被拒绝而非迁移。由于介质是共享且用户可见的，读取会校验每个字段。单条不可用的行会被丢弃而其同伴保留；无法解析的文本或异版本文件读作空——另一个 harness 版本写入的一条损坏记录，不得隐藏所有其他存活会话。上述任一情况都会把介质标记为受损，下一次写入将重新发布并修复它。
+
+## 配置
+
+| 键 | 类型 | 默认值 | 含义 |
+| --- | --- | --- | --- |
+| `root` | string | 必填——无默认值（回退到 cwd 会使注册表散落各处） | 存放 `sessions.json` 的目录；按需以 `0o700` 创建 |
+| `lockStaleMs` | natural | `10000` | 持有的锁超过该毫秒数即视为被遗弃并被回收 |
+| `lockRetries` | natural | `10` | 锁争用时在明确失败前的重试次数 |
+
+## 模型体验
+
+无。本包不注册工具、不注入提示词、不追加会话事件；它只为 CLI 列表界面存储宿主侧进程记录。
+
+#### KV 缓存影响
+
+与在途请求无关：注册表从不触碰请求前缀，因此这里不会使提供方缓存复用失效。
+
+## 已知限制与后续工作
+
+- **陈旧窗口内被复用的 pid 会被信任**——`bootId` 能区分本进程所写记录的 incarnation，但外来记录的 pid 若已被操作系统重新分配给无关的存活进程，在其属主移除之前会一直被报告为存活。

+
+English | [中文](README.zh.md)
+
+Publishes every live session in this process into the [session registry](../session-registry/README.md), so `dsh list-sessions` lists the sessions a server creates on demand rather than only the one a launcher minted up front.
+
+## Behavior
+
+Registration follows session lifecycle rather than a launcher-known identity: the plugin publishes every session present at mount and every later `session/created`, and removes a record when its session is disposed. One path therefore serves both the TUI's single session and the browser UI's one-per-conversation sessions.
+
+A session whose header carries no `cwd` is skipped — the listing's workspace column would have nothing truthful to show.
+
+`session/title` events are mirrored onto the record through `retitle`, so the latest logged title reaches the listing. Carrying the title in the record is what keeps the reader backend-agnostic: the log's location, file format, and compression are per-deployment choices (the shipped TUI writes zstd-compressed JSONL), so an independent process cannot portably parse one.
+
+Publication is fire-and-forget with a warning on failure: the registry is an observability aid, so a registry fault must not fail a working agent session. A session that ends while its registration is still in flight leaves a tombstone the completing registration observes, so its record cannot outlive the session until a pid-based prune.
+
+## Config
+
+None. Every published record is derived from the session itself, so no deployment-varying choice is left to configure.
+
+## Model Experience
+
+None, as this package registers no tools, injects no prompts, and appends no session events; it only mirrors existing lifecycle and title events into a host-side process record.
+
+#### KV Cache effect
+
+Independent of live requests: the plugin reads session events and writes a separate registry file without touching any request prefix, so it cannot invalidate provider cache reuse.
+
+## Known Limitations and Deferred Work
+
+- **A skipped session is invisible, not deferred** — a session created without a `cwd` is never published, even if a workspace becomes known later; there is no re-check.
+- **Title mirroring costs one registry write per revision** — each `session/title` event triggers a locked read-modify-write, so a deployment with an aggressive retitling cadence pays that write per revision.

+# @deepseek-ai/dsh-session-registry-live
+
+[English](README.md) | 中文
+
+把本进程内每个活跃会话发布到[会话注册表](../session-registry/README.md)，因此 `dsh list-sessions` 能列出服务端按需创建的所有会话，而不是只列出启动器一开始铸出的那一个。
+
+## 行为
+
+注册跟随会话生命周期，而不依赖启动器已知的身份：插件会发布挂载时已存在的每个会话，以及此后每个 `session/created`，并在会话被 dispose（资源释放）时移除对应记录。因此同一条路径既服务 TUI 的单个会话，也服务浏览器 UI 的每对话一个的多个会话。
+
+会话头不带 `cwd` 时会被跳过：列表的工作区列拿不到任何真实内容可展示。
+
+`session/title` 事件通过 `retitle` 镜像到记录上，因此最新记录的标题能到达列表。把标题带在记录里，正是让读取方与后端无关的原因：日志的位置、文件格式和压缩都是逐部署的选择（随附的 TUI 写入 Zstandard 压缩的 JSONL），因此独立进程无法以可移植的方式解析它。
+
+发布是 fire-and-forget，失败只发出警告：注册表是一项可观测性辅助设施，因此注册表故障绝不能让正常工作的 agent（智能体）会话失败。会话在其注册仍在途中时结束，会留下一个 tombstone，让即将完成的注册观测到，因此它的记录不会一直存活到某次基于 pid 的清理才消失。
+
+## 配置
+
+无。每条发布的记录都从会话本身派生而来，因此没有留下任何逐部署的选择需要配置。
+
+## 模型体验
+
+无。该包（package）不注册工具、不注入提示词，也不追加会话事件；它只把既有的生命周期事件和标题事件镜像进宿主侧的进程记录。
+
+#### KV 缓存影响
+
+与实时请求相互独立：该插件读取会话事件，并写入一个独立的注册表文件，不触碰任何请求前缀，因此它无法使提供方 cache 复用失效。
+
+## 已知限制与延期工作
+
+- **被跳过的会话是不可见，而非延后处理**——创建时不带 `cwd` 的会话永不发布，即使之后工作区变为已知也不会；没有重新检查机制。
+- **标题镜像每次修订都要付出一次注册表写入**——每个 `session/title` 事件都会触发一次加锁的读取、修改和写入，因此改名节奏激进的部署要按修订次数付出这些写入。

+English | [中文](README.zh.md)
+
+Live-session registry seam (`ctx.sessionRegistry`): the contract and record vocabulary for a cross-process registry of the sessions running right now, so a separate short-lived process such as `dsh list-sessions` can answer "what am I running". This package owns no medium — a backend (the lock-guarded JSON file in [`session-registry-file`](../session-registry-file/README.md) today, a database later) implements the abstract service.
+
+## Shape
+
+- `register(registration)` — publish `{ sessionId, cwd, title? }` stamped with this process's pid, a per-incarnation `bootId`, and `startedAt`. Replaces any existing record for the same session id. Returns the `ctx.effect` disposer; awaiting it waits for the removal to reach durability.
+- `retitle(sessionId, title)` — replace the recorded title of a session **this** process registered. Titles arrive after registration and can be revised, so it is the one mutable field. A record owned by another pid or incarnation is left alone, and an unknown id is a no-op because a title can resolve after the record is gone.
+- `list()` — every live record, newest registration last. Liveness is part of the contract, not the backend's discretion: every returned record's process existed at observation time, so a process killed without running its disposer leaves no permanent phantom.
+
+Backends serialize mutations against concurrent registrars — other processes and overlapping calls in this one — so records are never lost to a torn read-modify-write.
+
+## Record vocabulary
+
+`SessionRegistryRecord` carries `sessionId` (unique across live records), `pid`, `cwd`, `startedAt`, a `bootId` distinguishing a recycled pid from the original incarnation, and an optional `title`. The title travels in the record rather than being read from the session log because log location, format, and compression are per-deployment backend choices an independent reader cannot portably parse.
+
+## Model Experience
+
+None, as this package registers no tools, injects no prompts, and appends no session events; it defines the host-side listing contract only.
+
+#### KV Cache effect
+
+Independent of live requests: the registry never touches a request prefix, so nothing here can invalidate provider cache reuse.
+
+## Known Limitations and Deferred Work
+
+- **Records are process-scoped, not agent-scoped** — only top-level launcher surfaces publish. In-process subagents have no process of their own, and out-of-process subagent backends spawn `dsh-jsonrpc-agent` rather than the CLI, so neither appears in a listing.
+- **Liveness is pid existence, not health** — a hung or stopped process still lists as running; the contract deliberately makes no judgement about whether a session is making progress.

+# @deepseek-ai/dsh-session-registry
+
+[English](README.md) | 中文
+
+存活会话注册表 seam（`ctx.sessionRegistry`）：定义跨进程「当前正在运行哪些会话」注册表的契约与记录词汇，使 `dsh list-sessions` 这类独立的短生命周期进程能够回答「我正在运行什么」。本包不拥有任何介质——由后端实现该抽象服务（今天是 [`session-registry-file`](../session-registry-file/README.md) 中加锁保护的 JSON 文件，将来可以是数据库）。
+
+## 形状
+
+- `register(registration)`：发布 `{ sessionId, cwd, title? }`，并盖上本进程的 pid、每个 incarnation 独有的 `bootId` 和 `startedAt`。同一会话 id 的既有记录会被替换。返回 `ctx.effect` disposer；await 它即等待移除达到持久性。
+- `retitle(sessionId, title)`：替换**本**进程注册的某个会话的已记录标题。标题在注册之后才到达，并且可以修订，因此它是唯一的可变字段。归属于其他 pid 或其他 incarnation 的记录不受影响；未知 id 为空操作，因为标题可能在记录消失之后才解析出来。
+- `list()`：返回全部存活记录，按注册时间从旧到新排列。存活性属于契约本身，而非后端的自由裁量：每条返回记录的进程在观察时刻都存在，因此未运行 disposer 就被杀掉的进程不会留下永久的幽灵记录。
+
+后端必须将变更与并发注册方（其他进程，以及本进程内相互重叠的调用）串行化，使记录不会因撕裂的读改写而丢失。
+
+## 记录词汇
+
+`SessionRegistryRecord` 携带 `sessionId`（在存活记录中唯一）、`pid`、`cwd`、`startedAt`、用于区分被复用 pid 与原 incarnation 的 `bootId`，以及可选的 `title`。标题随记录传递而非从会话日志读取，因为日志的位置、格式与压缩是各部署后端的选择，独立读取方无法可移植地解析。
+
+## 模型体验
+
+无。本包不注册工具、不注入提示词、不追加会话事件；它只定义宿主侧的列表契约。
+
+#### KV 缓存影响
+
+与在途请求无关：注册表从不触碰请求前缀，因此这里不会使提供方缓存复用失效。
+
+## 已知限制与后续工作
+
+- **记录以进程为粒度，而非以 agent 为粒度**——只有用户直接启动的顶层界面会发布。进程内 subagent 没有自己的进程，进程外 subagent 后端启动的是 `dsh-jsonrpc-agent` 而非本 CLI，两者都不会出现在列表中。
+- **存活性只表示 pid 存在，不表示健康**——挂起或停止的进程仍会被列为运行中；契约刻意不判断会话是否在推进。

A pin owns its generated `system-prompt.expected.md` or `tool-schemas.expected.json` by default; `systemPromptSource` and `toolSchemasSource` name another pin when the complete corresponding sequence is identical, so each distinct version is committed once. The pin's `session.jsonl` stores `"system":"{{system}}","tools":"{{tools}}"` while retaining config, reason, and any model-visible prefix. A pin with legitimate mid-run header changes declares `expectedHeaderChanges`; a shared source must declare the same count, and record/refresh rejects claimants that generate different bytes.

A pin owns its generated `system-prompt.expected.md` or `tool-schemas.expected.json` by default; `systemPromptSource` and `toolSchemasSource` name another pin when the complete corresponding sequence is identical, so each distinct version is committed once. The pin's `session.jsonl` stores `"system":"{{system}}","tools":"{{tools}}"` while retaining config, reason, and any model-visible prefix. A pin with legitimate mid-run header changes declares `expectedHeaderChanges`; a shared source must declare the same count, and record/refresh rejects claimants that generate different bytes.
 
 Every scenario compares `stdout.expected.jsonl` with cwd-rooted separators canonicalized to `/`. On Windows, `pinsNativeWindowsStdout` additionally compares the complete `stdout.expected.windows.jsonl` after the shared expected output and requires that sidecar exactly when enabled. A scenario whose driven behavior needs POSIX process semantics (e.g. cancelling a live bash call kills a detached process group) declares `posixOnly`, which skips its run test on Windows while the fixture guards keep covering its committed files everywhere.

 每个场景都比较 `stdout.expected.jsonl`，其中以 cwd 为根的分隔符规范化为 `/`。在 Windows 上，`pinsNativeWindowsStdout` 还会在共享预期输出之后比较完整 `stdout.expected.windows.jsonl`，并在启用时精确要求该 sidecar。驱动行为需要 POSIX 进程语义的场景（例如取消实时 bash 调用会终止脱离进程组）声明 `posixOnly`，在 Windows 上跳过运行测试，但 fixture 保护仍在所有平台覆盖其已提交文件。

+name: dsh-migrate
+description: Migrate a user's setup from another coding agent (opencode, pi, Claude Code, Codex) to DSH — porting instruction files, custom commands and skills, hooks, MCP servers, and API/env configuration into their DSH equivalents. Use when the user asks to migrate, switch, or move from another coding agent to DSH.
+---
+
+# DSH Migrate
+
+Move a user's existing coding-agent setup onto DSH: instruction files, custom commands, skills, hooks, MCP servers, and API/environment configuration. Port only what has a real DSH equivalent; tell the user plainly when something has none.
+
+## First: identify the source
+
+Ask which agent the user is migrating from if they have not said: **opencode**, **pi**, **Claude Code**, or **Codex**. The mapping differs per source. Then locate that agent's config (ask the user, or inspect the obvious locations: `~/.claude/` and `.claude/` for Claude Code, `~/.codex/` and `.codex/` for Codex, the opencode/pi config dir the user names). Read what exists before proposing changes; never invent files the user does not have.
+
+## DSH targets
+
+Every migration lands in one of these DSH surfaces. Verify the exact path against the running install rather than assuming.
+
+- **Workspace instructions**: DSH reads `AGENTS.md` and `CLAUDE.md` (and `AGENTS.local.md` / `CLAUDE.local.md`) from the project, walking up to the project root, plus a user-global `~/.dsh/AGENTS.md`. `CLAUDE.md` is read as-is, so a Claude Code project needs no rename.
+- **Personal overlay** (user-global, applies to every DSH session): the Harness home `~/.dsh/` holds `config.yaml` (a top-level YAML array of Loader patch entries that patch the booted plugin tree), `.env` (fills environment gaps only — ambient env and the invoking directory's `.env` win), `AGENTS.md`, and `skills/`.
+- **Skills**: directory-bundle or flat-Markdown skills load from `.dsh/skills/` and `.agents/skills/` in the project, and `~/.dsh/skills/` and `~/.agents/skills/` for the user. Personal skills go in `~/.dsh/skills/<name>/SKILL.md`. Use the `skill-creator` skill to author them.
+- **Hooks**: DSH runs a mapped subset of an existing Claude Code or Codex hook config through compatibility bridges — no rewrite needed for the supported subset. See the per-source sections.
+- **MCP servers**: DSH has no native MCP client. Reach MCP servers through the `mcporter` skill / CLI, which can call servers already configured for other tools.
+- **API / model config**: DSH uses `DEEPSEEK_API_KEY` (and optional `DEEPSEEK_BASE_URL`) from `.env` (root, invoking directory, or `~/.dsh/.env`). Model and provider are chosen in the booted `cordis.yml` / personal overlay, not per-provider config files.
+
+## Per-source mapping
+
+### Claude Code
+
+- `CLAUDE.md` → read as-is by DSH workspace instructions; keep it, or consolidate into `AGENTS.md`. User-global rules → `~/.dsh/AGENTS.md`.
+- `.claude/hooks.json` (or a settings file's `hooks` key) → the `@deepseek-ai/dsh-hooks-claude` bridge runs the mapped command-hook subset on DSH's interception seams, with `${CLAUDE_PLUGIN_ROOT}` / `${CLAUDE_PROJECT_DIR}` substitution. Add it to the booted `cordis.yml` (or personal overlay) pointing `configPath` at the existing file. Anything outside the mapped subset should become a native DSH plugin, not a shimmed hook.
+- Slash commands → DSH commands are plugin-provided; there is no drop-in import. Reimplement genuinely needed ones as skills (`~/.dsh/skills/`) or plugins.
+- MCP servers in Claude config → use `mcporter` to reach them; DSH has no native MCP.
+- `ANTHROPIC_API_KEY` etc. do not transfer; DSH is DeepSeek-backed via `DEEPSEEK_API_KEY`.
+
+### Codex
+
+- Codex `AGENTS.md` → DSH already reads `AGENTS.md`; keep it. User-global → `~/.dsh/AGENTS.md`.
+- Codex hook config → the `@deepseek-ai/dsh-hooks-codex` bridge runs a deliberate subset (`PreToolUse`, `PostToolUse`, `SessionStart`, `UserPromptSubmit`, `Stop`; regex-only matchers; no plugin env injection; no pre-tool approval/rewrite). Add the bridge to the booted config with `configPath` at the existing Codex hooks file. State the unsupported points to the user rather than implying full parity.
+- MCP servers → `mcporter`.
+- API/env → `DEEPSEEK_API_KEY` in `.env`.
+
+### opencode / pi
+
+- These have no compatibility bridge. Port by concept, not by file:
+  - Agent/system instructions → `AGENTS.md` (project) and `~/.dsh/AGENTS.md` (user-global).
+  - Provider/model and any plugin-style tuning → the booted `cordis.yml` or `~/.dsh/config.yaml` overlay patches; API keys → `.env`.
+  - Reusable prompts/commands → skills under `~/.dsh/skills/`.
+  - MCP servers → `mcporter`.
+- pi has no native MCP by design; the `mcporter` route is the same as for DSH.
+
+## Do the migration
+
+1. Confirm the source agent and read its actual config.
+2. For each capability (instructions, hooks, commands/skills, MCP, API/env), map it to the DSH target above, or tell the user it has no equivalent.
+3. Write the ported files (`AGENTS.md`, `~/.dsh/AGENTS.md`, `~/.dsh/config.yaml`, `~/.dsh/.env`, skills). For hook bridges, add the plugin entry to the booted config.
+4. Verify: hooks need the bridge plugin present in the running tree; MCP needs `mcporter` reachable; API needs `DEEPSEEK_API_KEY` set. Test in a real DSH session, not just on paper.
+5. Summarize what was ported, what was reimplemented, and what has no DSH equivalent.

From f290a8b8513f82757f0348ac58a655e770ff94ff Mon Sep 17 00:00:00 2001
From: Turtle <turtle1999@deepseek.com>
Date: Wed, 29 Jul 2026 13:58:21 +0800
Subject: [PATCH 038/212] refactor(cli)!: one shared base config with
 per-surface overlays
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`dsh` shipped two config trees that were 43 rows the same: apps/cli/cordis.yml
composed web as 74 flat rows, while the TUI booted examples/tui-agent/cordis.yml
whose single `@deepseek-ai/dsh-tui-demo` row mounted twelve plugins behind a
twenty-key pass-through Config. Neither file was what its location claimed —
apps/cli hardcoded the "example" as the product default and the "demo" bundle
was the application — and every capability change had to be made twice.

- apps/cli/base.cordis.yml holds the 43 shared rows; tui.cordis.yml and
  web.cordis.yml are patch lists stating only what differs per surface
- overlays apply as SIBLING patch lists at one include level, because include
  patches never cross an include boundary. Precedence: base < surface <
  (--config | personal ~/.dsh/config.yaml) < launcher flag/profile patches
- `--config` now applies an overlay INSTEAD OF the personal one, so a demo or
  test tree never inherits the user's route; new `--config-replace` boots a file
  as the entire tree (the old `--config` behaviour). Both survive /resume
- vendor/include: index each `insert`ed row as it is added so a later patch can
  configure or disable it. Upstream built the id index once before the patch
  loop, leaving every surface-only row — the whole TUI front door — silently
  unpatchable from user config. Logged as local modification 8
- session identity moves to dsh-agent-loop's CONFIGURED_AGENT_IDENTITIES_KEY;
  dsh-tui's MAIN_SESSION_ID_KEY is deleted (only the bundle read it)
- delete examples/tui-agent, examples/cordis-agent, packages/examples/tui-demo;
  TUI tests → apps/cli/tests, cordis e2e → packages/cordis/tool-cordis/tests,
  examples/code-mode survives as an overlay leaf
- `dsh web` gains --config, threaded into AppCLIEntry as an extra overlay

Three latent defects surfaced and are fixed here: the TUI captured the optional
sessionQuery service once at construction and could permanently disable /resume
when it won the mount race; the session-store root silently reverted to a
project-local ./.sessions; --config-replace was dropped by the resume handoff.

Verified by booting each tree through the real Loader (TUI 55 entries, web 75,
zero unsettled) rather than reading YAML. All eight terminal snapshots replay
byte-identically; 14/14 PTY smoke, 112/112 snapshots, 25/25 doc-sync, hygiene
and lint clean.

 Costs accepted: the vendored Loader carries idle machinery in the browser (EntryTree persistence is a no-op, groups/isolation unused); every plugin edit in dev pays a bundle rebuild plus fiber remount; graph `inject` rows are informational — activation truth is service-level — so a mismatch surfaces at the settled sweep, not at graph validation; and the three not-yet-promoted libraries keep their static-import export surface until their DI conversions land.
 
-Roster endgame (landed 2026-07-25 with the config-tree boot move): the roster lives in `apps/cli/cordis.yml`, `mountWebPlugins` and the `CLIENT_PACKAGES` constant are gone, and recomposing a deployment means swapping the yml/overlay. The graph composer moved from a webserver-side registry into the `dsh-client-modules` node half (the package upgraded to dual-face per this note's promotion rule — its consumer now reaches it through cordis DI), and the transport split landed alongside: the webserver became a plain route-registration plugin, `/api/*` binding moved to the connection node half over the upgraded `api-gateway` plugin (`dsh-host-apiproxy` providing `ctx.apiProxy`), and the dev bundle watch + SSE channel moved to the hmr node half.

 ## Decision
 
-**Composition is one flat config tree.** `apps/cli/cordis.yml` holds every row — the host runtime (32 rows), the `api-gateway` row, the `webserver` row, and the `dshClient` rows (the browser roster; the modules row is simultaneously a host row). No spine bundle: every plugin is one row and every config field is yml-editable. `--dev` appends the `dsh-client-hmr` row in code before the settle sweep — prod and dev differ by exactly that row. Row order carries no load semantics; activation is service-availability driven, and the boot compensates with a fail-loud triple: `assertEntriesLoaded` (import failures), `installFailLoud` (late apply rejections), and an all-ACTIVE sweep (PENDING fibers — cordis inject waiting has no timeout).

No spine bundle: every plugin is one row and every config field is yml-editable. That stance later became repository-wide, with the rows both surfaces share factored into `apps/cli/base.cordis.yml` and each surface reduced to an overlay ([shared-base overlays](../simplification/2026-07-29-shared-base-config-overlays.md)). `--dev` appends the `dsh-client-hmr` row in code before the settle sweep — prod and dev differ by exactly that row.

 **Boot glue is a class pair.** `AppCLIEntry` (apps/cli) and `AppWebEntry` (the shell kernel) hold only what must exist independently of cordis: argv facts, the composed patch set, the parsed boot manifest, the module system instance, loading-page handles — everything else lives in plugins. `AppCLIEntry.run()` is three stages: layered env (ambient > cwd `.env` > `$DSH_HOME/.env`, closing the defect above) → patch composition → Loader include boot plus the triple. `AppWebEntry.run()` mirrors it browser-side: parse `window.__DSH_BOOT__` into a `BootManifest` (two views: npm-package rows for the module table, cordis-plugin rows for entry composition; malformed wire throws), build the module system, render the loading page, prefetch the `immediately` tier in parallel with Context/Loader setup, **await the prefetch before creating entries** (materialization is `tree.import`'s synchronous require, unprotected by fiber inject waiting; cross-package require edges such as i18n → runtime/client need every immediately-tier factory registered first — an empirically found 10–25% boot race otherwise), adopt the modules entry, create the graph rows, settle, sweep.

Neither varies by deployment — both are properties of how the process was invoked, which only the launcher knows.
 
 Routing them through YAML made them silently droppable. `@cordisjs/plugin-include` applies a targeted patch by replacing whole top-level keys (`target[key] = value`), so a personal `~/.dsh/config.yaml` patching the `tui-agent` entry's `config` replaces the shipped block entirely. A user overlay written to change provider and model therefore deleted every resume key it did not restate, and nothing reported it: absent `resumeCommand` legitimately means "no fallback configured".

+Both sit beside the existing `tuiResumeHost` host capability, which set the precedent — a resume host has always been a provided capability rather than config. Each slot is declared by the package that consumes it:
 
-- `MAIN_SESSION_ID_KEY` carries a `MainSessionIdentity` (`{ id: SessionId, resume: boolean }`). `dsh-tui-demo` binds both the TUI and the configured agent to `id`, and takes the history-loading `resumeSessionId` path only when `resume` is set, because that path requires an existing log and fails loud without one. An absent slot means no launcher chose a session, so the app mints `main-session-<uuid>` and creates it fresh.
-- `TUI_GOODBYE_MESSAGE_KEY` carries the complete line printed once the terminal is released on exit. Absent prints nothing.
+- `CONFIGURED_AGENT_IDENTITIES_KEY` (`dsh-agent-loop`) carries launcher identities keyed by configured-agent `id`, each a `LauncherAgentIdentity` (`{ id: SessionId, resume: boolean }`). `agent-loop` applies the matching identity over its configured agent, replacing both identity keys, and takes the history-loading `resumeSessionId` path only when `resume` is set, because that path requires an existing log and fails loud without one. An absent slot leaves the configured identity untouched. The `tui` row resolves the same id through its own `sessionId` key, so the front door renders exactly the agent that was bound.
+- `TUI_GOODBYE_MESSAGE_KEY` (`dsh-tui`) carries the complete line printed once the terminal is released on exit. Absent prints nothing.
+
+Identity belongs to `agent-loop` because that is the plugin which creates configured agents, and because a patch replaces a row's whole `config`: an overlay repointing the agent row's model route would erase a launcher-set identity key. See [the shared-base overlay note](../simplification/2026-07-29-shared-base-config-overlays.md).
 
 `apps/cli` mints or selects the id and builds the line from the invocation it is reproducing, sharing one `resumeArgs` helper with the `/resume` execve handoff so the printed command and the in-place handoff cannot diverge. The line now names `--config` when one was passed, and reproduces `dsh meta --resume <id>` in meta mode — closing the mode-aware hint deferred by the `dsh meta` note, where a copied hint previously only worked from the checkout.

 Verified live in tmux against the real personal overlay: the defect reproduced on unmodified staging (requested id ignored, fresh id in the banner), and on this branch the same overlay yields a printed exit line, a `--resume` that restores the prior turn, and a `/resume` selector marking the session `current · live · persisted`. A wrong id now fails loud.

 The vm isolates accidental global pollution, and the context façade hides framework internals. Neither restricts the authority of exposed services: a temporary Plugin can call `ctx.bash` with the host executor's privileges and reach the real filesystem and web services. It runs in the shared DSH runtime and may affect other sessions in that process. This is an opt-in development tool with bash-equivalent trust, not a security boundary or product default.

 `/resume` could only reach sessions started in the launch directory, so returning to yesterday's work in another project meant remembering its path, leaving the TUI, and relaunching there. Two independent causes produced that limit, and fixing either alone changes nothing.
 
-Storage was the binding one. The shipped `tui-demo` bundle defaulted `persistenceRoot` to a relative `./.sessions`, so each launch directory owned a disjoint JSONL root and a disjoint derived `session-query.db`. Sessions from another project were not filtered out of the listing — they were absent from the store the listing reads. The JSONL backend already partitions per-cwd *inside* one root, so the partitioning was doubled: once by root, once within it.
+Storage was the binding one. The shipped TUI composition defaulted its persistence root to a relative `./.sessions`, so each launch directory owned a disjoint JSONL root and a disjoint derived `session-query.db`. Sessions from another project were not filtered out of the listing — they were absent from the store the listing reads. The JSONL backend already partitions per-cwd *inside* one root, so the partitioning was doubled: once by root, once within it.
 
 The picker then filtered again. It dropped records whose `cwd` differed from the current session before display, and `summarizeResumeCandidate` independently marked a differing `cwd` as `disabledReason: 'different workspace'`, so a foreign session that did reach the store was both hidden and refused.

 **Storage.** `dsh-paths` owns the location as `resolveSessionsRoot()` (`sessions` under the Harness home, by `resolveDshHome`'s precedence), but only the launcher assumes it: shared-store policy is the dsh CLI's, never a plugin's. The TUI surface provides the root through the `SESSIONS_ROOT_KEY` boot slot (`ctx.provide` before Loader entries mount) and `dsh web` patches the same root in `apps/cli/src/app-cli-entry.ts`. Two CLI surfaces computing that path independently is exactly the failure this change fixes — disjoint stores — so the fact gets one home rather than a `join` per caller, alongside the existing `registryRoot()` precedent for `run`.
 
-`tui-demo` itself keeps a project-local `./.sessions` default and reads the launcher slot between explicit config and that default (`config.persistenceRoot ?? ctx.get(SESSIONS_ROOT_KEY) ?? './.sessions'`). The precedence lives in `composeTuiApp`, not as a schemastery `.default()`, because a schema default would materialize before the compose function runs and shadow the slot for every Loader mount. `examples/tui-agent/cordis.yml` omits `persistenceRoot` so the launcher slot (or, for a bare example boot, the project-local default) applies. Configuring an explicit root always wins, which remains the correct choice for a hermetic deployment.
+The shared base states that precedence in the row itself: `apps/cli/base.cordis.yml`'s `session-persistence-jsonl` row reads `root: !!js launcherSessionsRoot ?? './.sessions'`, so the launcher slot wins and a bare boot without one keeps the project-local default. Expressing it as the row's own `!!js` value rather than a schemastery `.default()` matters for the same reason it did in the bundle: a schema default would materialize before the slot could be read. An overlay or personal patch that states an explicit root always wins, which remains the correct choice for a hermetic deployment.
 
 **Scope, not exclusion.** A workspace other than the current one is a display scope rather than a disabled reason. `showResume()` summarizes every record and the `ResumePicker` owns a `scope` of `'workspace' | 'all'`, defaulting to the current workspace so the common case is unchanged. Tab toggles; the scope line names the active scope and the count the other holds; each row in the all-workspaces scope reports its own workspace, and that label joins the searchable text only in the scope that shows it. A toggle clears the query and selection so the highlighted row always belongs to the visible list, and the per-row workspace line makes a row one terminal row taller in that scope, which the visible-count budget accounts for.

 `/resume` 只能触达在启动目录中创建的会话，因此要回到昨天在另一个项目里的工作，就得记住它的路径、退出 TUI、再到那里重新启动。造成这一限制的原因有两个，彼此独立，只修其中一个都不会有任何变化。
 
-存储是那个决定性的原因。已交付的 `tui-demo` 组合包把 `persistenceRoot` 默认成相对路径 `./.sessions`，于是每个启动目录都独占一份互不相交的 JSONL 根目录，以及一份互不相交的派生 `session-query.db`。来自另一个项目的会话并不是在列表中被过滤掉的——它们根本不存在于列表读取的存储中。JSONL 后端本来就会在*同一个*根目录*内部*按 cwd 分区，所以分区被叠加了两层：一层按根目录，一层在根目录内部。

 接着选择器又过滤了一次。它在展示前丢弃 `cwd` 与当前会话不同的记录，而 `summarizeResumeCandidate` 又独立地把不同的 `cwd` 标记为 `disabledReason: 'different workspace'`，于是一个确实进入了存储的外部会话既被隐藏，也会被拒绝。

 **存储。** `dsh-paths` 以 `resolveSessionsRoot()` 拥有该位置（按 `resolveDshHome` 的优先级，取 Harness home 下的 `sessions`），但只有启动器假定它：共享存储策略属于 dsh CLI，绝不属于插件。TUI 界面通过 `SESSIONS_ROOT_KEY` 启动槽位（在 Loader 条目挂载前 `ctx.provide`）提供该根目录，`dsh web` 则在 `apps/cli/src/app-cli-entry.ts` 中为同一根目录打补丁。CLI 的两处界面各自独立计算该路径，正是本次改动所修复的那种失败——互不相交的存储——因此这项事实只有一个归属，而不是每个调用方各做一次 `join`，这与 `run` 已有的 `registryRoot()` 先例一致。
 
-`tui-demo` 自身保持项目本地的 `./.sessions` 默认值，并在显式配置与该默认值之间读取启动器槽位（`config.persistenceRoot ?? ctx.get(SESSIONS_ROOT_KEY) ?? './.sessions'`）。这一优先级放在 `composeTuiApp` 内，而不是写成 schemastery 的 `.default()`，因为 schema 默认值会在 compose 函数运行前物化，使每次 Loader 挂载都遮蔽该槽位。`examples/tui-agent/cordis.yml` 不写 `persistenceRoot`，因此启动器槽位（裸示例启动时则为项目本地默认值）生效。显式配置的根目录总是获胜，对于封闭部署来说这仍然是正确的选择。
+共享 base 直接在配置项自身表达这一优先级：`apps/cli/base.cordis.yml` 的 `session-persistence-jsonl` 配置项写作 `root: !!js launcherSessionsRoot ?? './.sessions'`，因此启动器槽位优先，而没有槽位的裸启动则保留项目本地默认值。把它写成配置项自身的 `!!js` 取值、而不是 schemastery 的 `.default()`，其原因与在组合包中相同：schema 默认值会在能够读取槽位之前就物化。若 overlay 或个人 patch 显式声明了根目录，则始终以其为准——对于要求自洽封闭的部署，这仍是正确选择。
 
 **是范围，不是排除。** 当前 workspace 之外的 workspace 是一种展示范围，而不是禁用理由。`showResume()` 汇总每一条记录，`ResumePicker` 持有一个 `'workspace' | 'all'` 的 `scope`，默认为当前 workspace，因此常见场景毫无变化。Tab 切换范围；范围行会说明当前生效的范围，以及另一个范围下的数量；在全 workspace 范围中每一行都报告自己的 workspace，而该标签只在展示它的范围里才加入可搜索文本。切换范围会清空查询和选中项，使高亮行始终属于可见列表；而逐行的 workspace 行会让该范围下的每一行在终端里多占一行，可见条数预算已经把这一点计入。

+# Agent Note: One shared base config with per-surface overlays
+
+Status: implemented
+
+English | [中文](2026-07-29-shared-base-config-overlays.zh.md)
+
+## Problem
+
+`dsh` shipped two full config trees that were 43 rows the same. `apps/cli/cordis.yml` composed the web surface as 74 flat rows, while the TUI booted `examples/tui-agent/cordis.yml`, whose single `@deepseek-ai/dsh-tui-demo` row mounted twelve plugins and re-declared their configuration as its own twenty-key pass-through `Config`.
+
+Neither file was what its location claimed. `examples/tui-agent` was not an example: `apps/cli/src/tui.ts` hardcoded it as the product's default config, and it owned the TUI PTY smoke, the eight terminal snapshot scenarios, and the PTY harness the `cordis-agent` leaf imported. `dsh-tui-demo` was not a demo either — it was the application, mounted by the shipped binary from `packages/examples/`.
+
+The duplication was the load-bearing problem. Of the 43 shared rows, 38 were byte-identical and 5 differed for a defensible per-surface reason, so every capability change had to be made twice and could silently drift. The bundle also inverted a default: `composeTuiApp` read `config.goals ?? {}`, so the shipped TUI mounted goals, `tool-goal`, `goal-session`, and `/goal` although no config key requested them.
+
+## Decision
+
+One shared base, one overlay per surface, composed as sibling patch lists.
+
+`apps/cli/base.cordis.yml` holds the 43 rows both surfaces mount. `apps/cli/tui.cordis.yml` and `apps/cli/web.cordis.yml` are **patch lists**, not trees: each states the handful of rows whose value is surface-specific and inserts its own rows. The launcher includes the base once and applies every overlay as a sibling patch list at **one** include level, because include patches never cross an include boundary — stacking overlays as nested includes would silently stop reaching base rows.
+
+Precedence is list order, last write winning per row: base, then the surface overlay, then either a `--config` overlay or the personal `~/.dsh/config.yaml`, then the launcher's own flag and profile patches.
+
+`--config <path>` now applies an overlay **instead of** the personal overlay, so a demo or test tree never inherits the user's provider and model. `--config-replace <path>` boots a file as the entire tree, bypassing base, surface overlay, and personal overlay alike; that is what the old `--config` did, so trees like `examples/web-cordis` moved to the new flag. Both flags survive the `/resume` execve handoff, or resuming would silently change the agent.
+
+A patch replaces its target row's whole `config` rather than merging, which shapes the split: a row whose value differs per surface lives in the overlays, never in the base, so no row is patched by three layers at once. Session identity therefore cannot ride a config key at all — it moved to `dsh-agent-loop`'s `CONFIGURED_AGENT_IDENTITIES_KEY`, as [the launcher-owned identity note](../architecture/2026-07-28-launcher-owned-resume-identity.md) now records.
+
+`examples/tui-agent`, `examples/cordis-agent`, and `packages/examples/tui-demo` are deleted. The TUI tests move to `apps/cli/tests/`, the cordis-toolset e2e to `packages/cordis/tool-cordis/tests/`, and `examples/code-mode` survives as a genuine example: an overlay that patches `tools.mode` and inserts the code runtime.
+
+## Alternatives considered
+
+**Leave both trees flat and duplicated.** Rejected: 43 rows maintained twice is the defect, and a gate asserting they stay identical would freeze the duplication rather than remove it.
+
+**Nest the overlays as includes (`code-mode` → `tui` → `base`).** Rejected after testing the Loader: patches do not cross an include boundary, so the outer file's patches are dropped with only a warning. A three-level chain left `tools` unpatchable, and a base behind one include made every personal patch a silent no-op.
+
+**Put the union of all rows in the base and have each overlay disable what it does not want.** Rejected: the base stops meaning "shared", and each surface carries rows it exists only to switch off.
+
+**Keep the per-surface rows in the base and let overlays patch them.** Adopted only for the five rows that must exist in both trees, because a patch cannot create a row. Their base entries carry the plugin name and the config both surfaces share; each overlay states the rest.
+
+## Consequences
+
+An overlay or `--config` tree that named `@deepseek-ai/dsh-tui-demo`, or patched the `tui-agent` row, no longer resolves. Overlays now patch the row that owns each key: the model route on `agent-loop`, the persona on `system-prompt`, presentation on `tui`.
+
+A patch whose `id` matches no row stays a Loader warning rather than an error. That is deliberate: one personal overlay is shared across surfaces, and `insert` rows match nothing by design, so a row that exists only under `web` must not fail the TUI's boot.
+
+`dsh web` gains `--config`, threaded into `AppCLIEntry` as an extra overlay. `AppCLIEntry` reads both the base and its surface overlay when recovering row defaults for its own patch merge, since a flag override must preserve the overlay's other fields on the same row.
+
+## Verification
+
+Composition is checked by booting each tree through the real Loader and inspecting settled entries, not by reading YAML: the TUI settles 55 entries and web 75, both with zero unloaded or unsettled rows, and web's `httpServer` up. The three-layer case (`base` + `tui` + `code-mode`) confirms `tools.mode` reaching `code` over the TUI overlay's `native`.
+
+All eight terminal snapshot scenarios replay byte-identically after moving, and the 14-case PTY smoke passes, including two cases that assert a personal overlay reaches an **inserted** row — the behavior the vendored `plugin-include` fix enables ([`vendor/README.md`](../../../../vendor/README.md) local modification 8, covered by `packages/ui/app-boot/tests/config-reload.spec.ts`).
+
+Flattening surfaced three latent defects, each fixed here: the TUI captured the optional `sessionQuery` service once at construction and so could permanently disable `/resume` when it won the mount race; the shipped session-store root silently reverted to a project-local `./.sessions`; and `--config-replace` was dropped by the resume handoff.

+# Agent Note: 一份共享 base 配置加各 surface 的 overlay
+
+Status: implemented
+
+[English](2026-07-29-shared-base-config-overlays.md) | 中文
+
+## 问题
+
+`dsh` 交付了两棵完整的配置树，其中 43 个配置项完全相同。`apps/cli/cordis.yml` 以 74 个平铺配置项组合 web surface，而 TUI 启动的是 `examples/tui-agent/cordis.yml`——其中单独一行 `@deepseek-ai/dsh-tui-demo` 挂载了十二个插件，并把它们的配置重新声明为自己那份二十个键、仅作透传的 `Config`。
+
+这两份文件都名不副实。`examples/tui-agent` 并不是示例：`apps/cli/src/tui.ts` 把它硬编码为产品的默认配置；它还拥有 TUI 的 PTY 冒烟测试、八个终端快照场景，以及被 `cordis-agent` 叶节点 import 的 PTY harness。`dsh-tui-demo` 也不是 demo——它就是应用本身，由交付的二进制从 `packages/examples/` 中挂载。
+
+真正决定性的问题是重复。43 个共享配置项中，38 个逐字节相同，5 个因各 surface 的正当理由而不同；因此每次能力改动都必须改两处，而且可能无声漂移。该组合包还反转了一个默认值：`composeTuiApp` 读取 `config.goals ?? {}`，于是交付的 TUI 挂载了 goals、`tool-goal`、`goal-session` 和 `/goal`——尽管没有任何配置键要求它们。
+
+## 决策
+
+一份共享 base，每个 surface 一份 overlay，以平级 patch 列表的形式组合。
+
+`apps/cli/base.cordis.yml` 持有两个 surface 都会挂载的 43 个配置项。`apps/cli/tui.cordis.yml` 与 `apps/cli/web.cordis.yml` 是 **patch 列表**，不是配置树：各自声明少数取值因 surface 而异的配置项，并 insert 自己的配置项。启动器只 include base 一次，并把每个 overlay 作为**同一** include 层级上的平级 patch 列表应用——因为 include patch 不会跨越 include 边界，把 overlay 堆叠成嵌套 include 会使其静默地无法触达 base 配置项。
+
+优先级即列表顺序，逐配置项后写者胜：base，然后是 surface overlay，接着是 `--config` overlay 或个人 `~/.dsh/config.yaml`，最后是启动器自身的 flag 与 profile patch。
+
+`--config <path>` 现在应用一个 overlay 来**取代**个人 overlay，因此 demo 或测试用的树绝不会继承用户的 provider 与 model。`--config-replace <path>` 则把某个文件作为整棵树启动，同时绕过 base、surface overlay 与个人 overlay；这正是旧 `--config` 的行为，所以像 `examples/web-cordis` 这样的树改用了新 flag。两个 flag 都会在 `/resume` 的 execve 交接中保留，否则 resume 会静默更换 agent。
+
+patch 会整体替换目标配置项的 `config` 而不合并，这决定了拆分方式：取值因 surface 而异的配置项住在 overlay 中，绝不住在 base 里，从而没有任何配置项会被三层同时 patch。因此会话身份根本不能经由配置键传递——它迁移到了 `dsh-agent-loop` 的 `CONFIGURED_AGENT_IDENTITIES_KEY`，如[启动器持有身份的 note](../architecture/2026-07-28-launcher-owned-resume-identity.md) 现在所记录。
+
+`examples/tui-agent`、`examples/cordis-agent` 与 `packages/examples/tui-demo` 均被删除。TUI 测试迁往 `apps/cli/tests/`，cordis 工具集的 e2e 迁入 `packages/cordis/tool-cordis/tests/`，而 `examples/code-mode` 作为一个名副其实的示例保留下来：一个 patch `tools.mode` 并 insert code runtime 的 overlay。
+
+## 备选方案
+
+**保留两棵平铺且重复的树。** 拒绝：43 个配置项维护两份正是缺陷本身，而用一个门禁断言二者保持一致只会固化重复，而非消除它。
+
+**把 overlay 嵌套成 include（`code-mode` → `tui` → `base`）。** 在对 Loader 实测后拒绝：patch 不会跨越 include 边界，因此外层文件的 patch 只会伴随一条告警被丢弃。三层链条使 `tools` 无法被 patch，而位于一层 include 之后的 base，会让每个个人 patch 都变成静默的空操作。
+
+**把所有配置项的并集放进 base，由各 overlay 禁用自己不需要的部分。** 拒绝：base 将不再意味着「共享」，而每个 surface 都要携带仅为将其关闭而存在的配置项。
+
+**把因 surface 而异的配置项留在 base 中，由 overlay 去 patch。** 仅对必须同时存在于两棵树中的那五个配置项采用，因为 patch 无法创建配置项。它们在 base 中的条目携带插件名与两个 surface 共享的配置，其余部分由各 overlay 声明。
+
+## 影响
+
+指名 `@deepseek-ai/dsh-tui-demo`、或 patch `tui-agent` 配置项的 overlay 与 `--config` 树将不再可解析。overlay 现在要 patch 拥有对应键的那一行：模型路由在 `agent-loop`，人设在 `system-prompt`，呈现设置在 `tui`。
+
+若某个 patch 的 `id` 不匹配任何配置项，Loader 仍只告警而不报错。这是有意为之：同一份个人 overlay 会跨 surface 共用，而 `insert` 配置项按设计本就不匹配任何目标，因此仅在 `web` 下存在的配置项不能让 TUI 启动失败。
+
+`dsh web` 新增 `--config`，作为一份额外 overlay 传入 `AppCLIEntry`。`AppCLIEntry` 在为自身 patch 合并恢复配置项默认值时会同时读取 base 与其 surface overlay，因为 flag 覆盖必须保留同一配置项上 overlay 的其他字段。
+
+## 验证
+
+组合的正确性通过用真实 Loader 启动每棵树并检查已就绪的条目来核对，而不是靠阅读 YAML：TUI 就绪 55 个条目、web 就绪 75 个，两者都没有未加载或未就绪的配置项，且 web 的 `httpServer` 已启动。三层叠加的情形（`base` + `tui` + `code-mode`）确认 `tools.mode` 越过 TUI overlay 的 `native` 达到了 `code`。
+
+全部八个终端快照场景在迁移后逐字节重放一致，14 个用例的 PTY 冒烟测试全部通过，其中两个用例断言个人 overlay 能触达一个 **insert 进来的**配置项——这正是 vendored `plugin-include` 修复所启用的行为（[`vendor/README.md`](../../../../vendor/README.md) 本地修改第 8 条，由 `packages/ui/app-boot/tests/config-reload.spec.ts` 覆盖）。
+
+平铺过程暴露出三处潜伏缺陷，均在此一并修复：TUI 曾在构造时一次性捕获可选的 `sessionQuery` 服务，因此在挂载竞争中胜出时会永久禁用 `/resume`；交付的会话存储根目录曾静默退回项目本地的 `./.sessions`；`--config-replace` 曾在 resume 交接中被丢弃。

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

 - 使用 `dsh --resume <session-id>` 恢复已持久化会话。当 Node 宿主公开 `process.execve` 时，还会提供 TUI 的原地移交宿主：选择器预检并刷新当前会话后，宿主会释放应用，并以规范化的恢复调用替换进程；不支持进程替换的运行时会让会话继续运行并给出提示。会话身份与退出行由本 CLI 拥有，而非由配置指定：它创建或选定 `main` 会话 id，并把该 id 以及可复现本次调用的确切命令一起提供到启动上下文（[`MAIN_SESSION_ID_KEY`](../../packages/ui/tui/README.md) 与 `TUI_GOODBYE_MESSAGE_KEY`）。任何 `cordis.yml` 键都无法移除恢复能力；缺失或无法读取的 id 会明确报错，而不会创建新会话；

 - 告知 agent 自身源码所在位置：启动后添加一个命名此 harness checkout 的提示词段。该路径从启动器的真实路径解析，因此在 PATH 符号链接和任意 cwd 下仍然有效，使自指的 `cordis` 工具集可以读取并修改它；

+          You are in plan mode. Stay in plan mode until exit_plan_mode succeeds or the user switches the session mode. Imperative language to implement changes means plan the implementation, not execute it. A user's conversational agreement — including an answer confirming something you asked — approves nothing and does not end plan mode; fold the confirmed decision into the plan and submit it through exit_plan_mode.
+
+          Explore first. Use non-mutating reads, searches, static analysis, and checks to ground the plan in the actual repository. Do not edit or write files, change configuration, run formatters or code generation that rewrites tracked files, commit, or otherwise carry out the plan. Prefer existing functions and patterns over new machinery.
+
+          The tool catalog stays the same across modes for request-cache stability. These plan-mode rules override any later tool description or guidance that suggests using mutation tools; those tools remain listed only to keep the request shape stable. Do not use todo_write to track this planning phase: it tracks implementation after an approved plan, while the plan itself belongs in exit_plan_mode.
+
+          Resolve discoverable facts by inspection. Use ask_user_question only for user-owned choices or material ambiguity that inspection cannot answer. Do not ask the user where code lives or how current behavior works when you can find out.
+
+          Make the plan decision-complete: state the goal and success criteria; group implementation changes by subsystem; identify public API, schema, and data-flow changes; cover edge cases, failure modes, tests, acceptance criteria, and explicit assumptions. Keep it concise enough to review but detailed enough that another engineer can implement it without making design decisions.
+
+          When ready, call exit_plan_mode with the complete plan markdown, starting with a # title. Make exit_plan_mode the only and final tool call in that assistant response: it presents the plan for approval, and implementation begins only in a later step after approval. Do not paste the final plan as a plain reply or ask "should I proceed?" through prose or ask_user_question. If review rejects it, incorporate the feedback and present again. If the review channel is unavailable or aborted, stay in plan mode and ask the user to switch modes manually; do not proceed with implementation.

-    section: |
-          You are in plan mode. Stay in plan mode until exit_plan_mode succeeds or the user switches the session mode. Imperative language to implement changes means plan the implementation, not execute it. A user's conversational agreement — including an answer confirming something you asked — approves nothing and does not end plan mode; fold the confirmed decision into the plan and submit it through exit_plan_mode.
-
-          Explore first. Use non-mutating reads, searches, static analysis, and checks to ground the plan in the actual repository. Do not edit or write files, change configuration, run formatters or code generation that rewrites tracked files, commit, or otherwise carry out the plan. Prefer existing functions and patterns over new machinery.
-
-          The tool catalog stays the same across modes for request-cache stability. These plan-mode rules override any later tool description or guidance that suggests using mutation tools; those tools remain listed only to keep the request shape stable. Do not use todo_write to track this planning phase: it tracks implementation after an approved plan, while the plan itself belongs in exit_plan_mode.
-
-          Resolve discoverable facts by inspection. Use ask_user_question only for user-owned choices or material ambiguity that inspection cannot answer. Do not ask the user where code lives or how current behavior works when you can find out.
-
-          Make the plan decision-complete: state the goal and success criteria; group implementation changes by subsystem; identify public API, schema, and data-flow changes; cover edge cases, failure modes, tests, acceptance criteria, and explicit assumptions. Keep it concise enough to review but detailed enough that another engineer can implement it without making design decisions.
-
-          When ready, call exit_plan_mode with the complete plan markdown, starting with a # title. Make exit_plan_mode the only and final tool call in that assistant response: it presents the plan for approval, and implementation begins only in a later step after approval. Do not paste the final plan as a plain reply or ask "should I proceed?" through prose or ask_user_question. If review rejects it, incorporate the feedback and present again. If the review channel is unavailable or aborted, stay in plan mode and ask the user to switch modes manually; do not proceed with implementation.

+# code-mode
+
+English | [中文](README.zh.md)
+
+Code Mode over the shipped TUI: the model stops calling one tool per turn and instead writes TypeScript programs for a single `run_code` tool, executed in a worker thread.
+
+This leaf is an **overlay**, not a tree. `dsh --config` includes the shared [`apps/cli/base.cordis.yml`](../../apps/cli/base.cordis.yml), applies the [`tui.cordis.yml`](../../apps/cli/tui.cordis.yml) surface overlay, then applies this file — all as sibling patch lists at one include level.
+
+## Run it
+
+```sh
+# repo root .env (gitignored) or exported env:
+#   DEEPSEEK_API_KEY=sk-…
+#   DEEPSEEK_BASE_URL=https://…   # optional; defaults to the public API
+pnpm run demo:code-mode
+```
+
+`pnpm run demo:code-mode acp` boots the same idea over the ACP transport from [`examples/acp-agent/code-mode.cordis.yml`](../acp-agent/code-mode.cordis.yml).
+
+## What the overlay changes
+
+| Row | Change |
+| --- | --- |
+| `tools` | `mode: code` — the wire registry collapses to `run_code` plus its generated TypeScript SDK prompt section |

+A patch replaces a row's whole `config` rather than merging into it, so each row above restates every key it owns. A patch whose `id` matches no row is skipped with a Loader warning, so renaming a row in the base or the surface overlay requires updating this file.
+
+## Model Experience
+
+The model sees one tool instead of the full native registry. Its request carries the `run_code` schema and a generated TypeScript SDK section describing the callable surface, which costs more prompt tokens up front but replaces many single-call turns with one program — fewer round trips and fewer intermediate tool results in the transcript. Because the tool catalog is part of the cached request prefix, switching modes invalidates the KV cache for the session.

+# code-mode
+
+[English](README.md) | 中文
+
+在交付的 TUI 之上启用 Code Mode：模型不再每轮调用一个工具，而是为单一的 `run_code` 工具编写 TypeScript 程序，并在 worker 线程中执行。
+
+本叶节点是一个 **overlay**，而不是配置树。`dsh --config` 会 include 共享的 [`apps/cli/base.cordis.yml`](../../apps/cli/base.cordis.yml)，应用 [`tui.cordis.yml`](../../apps/cli/tui.cordis.yml) surface overlay，再应用本文件——三者都是同一 include 层级上的平级 patch 列表。
+
+## 运行
+
+```sh
+# repo root .env (gitignored) or exported env:
+#   DEEPSEEK_API_KEY=sk-…
+#   DEEPSEEK_BASE_URL=https://…   # optional; defaults to the public API
+pnpm run demo:code-mode
+```
+
+`pnpm run demo:code-mode acp` 通过 ACP 传输启动同样的思路，配置位于 [`examples/acp-agent/code-mode.cordis.yml`](../acp-agent/code-mode.cordis.yml)。
+
+## 该 overlay 改动了什么
+
+| 配置项 | 改动 |
+| --- | --- |
+| `tools` | `mode: code`——线上注册表收敛为 `run_code`，外加其生成的 TypeScript SDK 提示词片段 |
+| `system-prompt` | 指示模型把相关工具调用批量写进一个程序的 persona |
+| `tui` | Code Mode 的欢迎行 |
+| `code-runtime` | 新插入：`@deepseek-ai/dsh-code-runtime-worker`，即 `run_code` 的执行 worker 线程 |
+
+其余部分——模型后端、执行器、文件系统工具、持久化、委派与前端入口——全部来自 base 与 TUI overlay。
+
+配置 patch 会整体替换该配置项的 `config`，而非与其合并，因此上表每一行都必须重述自己拥有的全部键。若某个 patch 的 `id` 不再匹配任何配置项，Loader 只会告警并跳过它，所以在 base 或 surface overlay 中重命名配置项时必须同步更新本文件。
+
+## Model Experience（模型体验）
+
+模型看到的是一个工具，而不是完整的原生注册表。其请求携带 `run_code` 的 schema 以及一段生成的 TypeScript SDK 说明，用于描述可调用面。这会在前置阶段消耗更多提示词 token，但把多个单次调用的轮次压缩为一个程序——往返更少，transcript 中的中间工具结果也更少。由于工具目录属于被缓存的请求前缀，切换模式会使该会话的 KV 缓存失效。

-# cordis-agent
-
-English | [中文](README.zh.md)
-
-The self-referential harness demo: the DeepSeek V4 coding spine on the full-screen TUI plus [`@deepseek-ai/dsh-tool-cordis`](../../packages/cordis/tool-cordis/README.md), which lets the model inspect the current DSH process, mount in-memory temporary Plugins, and unmount them. Temporary Plugins remain active across turns but disappear on unmount, toolset unload, or DSH restart; they create no files or configuration and may affect other sessions in the process. The `ctx.fs` and `ctx.web` services are provider-only capabilities available to those Plugins. The design lives in [the toolset Agent Note](../../.agents/notes/implemented/feature/2026-07-08-self-referential-cordis-toolset.md).
-
-## Run it
-
-```sh
-# repo root .env (gitignored) or exported env:
-#   DEEPSEEK_API_KEY=sk-…
-#   DEEPSEEK_BASE_URL=https://…   # optional; defaults to the public API
-pnpm run demo:cordis      # TUI (default)
-pnpm run demo:cordis web  # browser UI at http://127.0.0.1:3081
-pnpm run demo:cordis acp  # ACP server
-```
-
-The intended demo is staged — verify the listener link first, then let the agent extend itself:
-
-```
-> Mount a temporary Plugin that listens to the 'agent/status' event and logs every status change, then run `echo hi` with bash.
-  [tool call] cordis_mount({"code": "return { name: 'status-logger', apply(ctx) { ctx.on('agent/status', (agent, status) => console.log('status →', status)) } }"})
-  [tool result] Temporary Plugin dyn-1 is running (plugin "status-logger"; available until unmounted or DSH restarts).
-  [tool call] bash({"command": "echo hi"})
-[cordis:dyn-1] status → …            ← the temporary listener firing, live
-> Now give yourself a reverse_text tool and use it on "harness".
-  [tool call] cordis_mount({"code": "return { name: 'reverse-text', inject: ['tools'], apply(ctx) { ctx.tools.register(harness.defineTool({ name: 'reverse_text', … })) } }"})
-  [tool call] reverse_text({"text": "harness"})   ← a tool the agent built for itself, one step earlier
-> Unmount both temporary Plugins.
-  [tool call] cordis_unmount({"id": "dyn-1"})
-```
-
-Ask for `cordis_inspect` with `what: "api"` or `what: "events"` to see the generated service/event reference used to write Plugin code, and mount two cooperating temporary Plugins (`ctx.provide` in one, `inject` in the other) to watch Cordis park and revive the consumer.
-
-## End-to-end tests
-
-`tests/keyless-smoke.e2e.ts` boots the real `cordis.yml` through the Loader with a dummy key and asserts the banner, package-name resolution, and clean EOF exit. `tests/cordis-tools.e2e.ts` is the with-key smoke: a real model mounts a temporary status listener and the test verifies its tagged console line, creates and uses a `reverse_text` tool, and composes two temporary Plugins through provide/inject. [`packages/cordis/tool-cordis`](../../packages/cordis/tool-cordis) carries the unit coverage under the per-file 100% gate.

-      {{model}} model.
-
-      You run INSIDE a cordis plugin runtime, and your cordis_* tools operate
-      on that live runtime: cordis_inspect to look around (its `api` and
-      `events` sections document the service methods, type shapes, and events
-      your Plugin code can use), cordis_mount to mount an in-memory temporary
-      Plugin (an event listener, a brand-new tool for yourself, or a service
-      another temporary Plugin injects), cordis_unmount to clean one up. These
-      Plugins remain across turns but disappear on unmount, toolset unload, or
-      DSH restart and may affect other sessions in this process. In Plugin code, NEVER use Node
-      built-ins (require/setTimeout/fetch) — use the runtime's cordis services
-      via inject: fs, web, bash, and timer (ctx.setTimeout). Prefer small
-      single-purpose plugins, prefer plain notification events over waterfall
-      events unless you intend to intercept, and unmount what you no longer
-      need. Report results briefly.

-# tui-agent
-
-English | [中文](README.zh.md)
-
-The full-screen interactive coding agent: DeepSeek V4, local bash and filesystem tools, compaction, subagents, workflows and fresh-agent Ralph iteration, plan mode (`/plan` enters and `exit_plan_mode` reviews the exit), timeout/spill policy, and JSONL persistence through [`@deepseek-ai/dsh-tui-demo`](../../packages/examples/tui-demo), loaded from `cordis.yml`. The sibling [`headless-agent`](../headless-agent/README.md) runs the same capability class as a one-shot pipe-friendly task, and [`acp-agent`](../acp-agent/README.md) serves it over JSON-RPC.
-
-## Run it
-
-```sh
-# repo root .env (gitignored) or exported env:
-#   DEEPSEEK_API_KEY=sk-…
-#   DEEPSEEK_BASE_URL=https://…   # optional; defaults to the public API
-pnpm run demo:tui
-```
-
-Both the demo script and the installable `dsh` CLI ([`apps/cli`](../../apps/cli/README.md)) boot this example's `cordis.yml` as the shipped default config; `dsh` additionally applies the personal overlay from `~/.dsh` and uses the invoking directory as the workspace.
-
-Type a coding task. The agent works through the `read`/`write`/`edit` filesystem tools for ordinary file operations and `bash` (+ the generic `task_output` / `task_list` / `task_kill` for background tasks) for shell commands, searches, and test runs, each in a fresh `bash -c` (the system prompt tells the model to pass `workdir` instead of `cd`). Both the fs tools and bash resolve relative paths against the session workspace. It can also delegate with `subagent`/`subagent_fork`.
-
-The `todo_write` task tracker is opt-in and not in the shipped config: add `@deepseek-ai/dsh-tool-todo` to `cordis.yml` (or a personal-config overlay under `~/.dsh`) to expose it. Once loaded, the model records a whole-list plan to the session log and the TUI renders it.
-
-The TUI renders Markdown history, reasoning, tool-owned terminal/diff/generic cards, token totals, and — when `todo_write` is loaded — the latest plan. Long tool bodies keep a head/tail preview; Ctrl+O expands or collapses every card. Enter submits or steers while the agent runs, Ctrl+R toggles reasoning, Escape cancels, and `/help` lists commands. `/plan` selects plan mode for the next step; `/plan <message>` also submits the message into that step, while `/plan off` selects the default mode without model input. `/status` expands the current session's identity, activity counts, exact token/cache buckets, context use, and timestamps without interrupting a running turn. `/model` opens a keyboard selector for the current provider catalog; use Up/Down to focus a model, Shift+Tab to cycle its advertised reasoning efforts, and Enter to select, or use `/model <model>` and `/model <provider>/<model>` for direct selection. `ask_user_question` opens a wide bottom-left keyboard panel with batch progress and numbered options.
-
-### Resuming a prior session
-
-Each run starts a fresh session by default (its event log lands under `./.sessions/`). To **continue** a previous conversation, pass its id to the installed `dsh` CLI — the `main` agent then rehydrates the persisted log instead of starting fresh, so the model sees the earlier turns as history:
-
-```sh
-dsh --resume <prior-session-id>
-```
-
-`/resume` opens a searchable keyboard selector with titles, activity, last-turn results, model route, durable goal phase, and live/persisted state. The installed `dsh` host flushes and disposes the current app, then replaces the process with `dsh --resume <id>`; a host that cannot hand off in place says so and leaves the session running. Resume needs no key in this file: `dsh` provides the session identity and the exit line on the boot context, so `--resume <id>` and the printed resume command survive any personal-overlay patch of the `tui-agent` entry. With no flag the agent starts a new session. A missing or unreadable id starts no agent and emits `agent-loop/config-start-failed`: the TUI prints the failure and exits nonzero. The selector has no cross-process session lock, so deployments with concurrent hosts must coordinate session ownership separately.
-
-## Code Mode
-
-[`code-mode.cordis.yml`](code-mode.cordis.yml) overlays the same tree with the worker-thread runtime and `tools: { mode: code }`. The model receives one `run_code` transport plus a generated TypeScript SDK for the visible tools; only program output returns to model context. Use `mode: both` to expose native calls alongside `run_code`. See the [Code Mode Agent Note](../../.agents/notes/implemented/feature/2026-06-15-code-mode.md) for the execution contract.
-
-```sh
-pnpm run demo:code-mode        # this overlay under the TUI (default UI)
-pnpm run demo:code-mode acp    # the acp-agent example's same-shaped overlay
-```
-
-Try a task that spans several tool calls, e.g.:
-
-> Count the lines of every `*.md` file under docs/ and write the three largest to summary.txt.
-
-and watch the transcript: one `run_code` call, a program looping over tools, and a result the model curated instead of five round-trips of raw tool output.
-
-## What each leaf entry demonstrates
-
-This example is a thin leaf `cordis.yml`: it picks the swappable backends, loads one app package, and adds product tools that are intentionally outside the shared spine. The spine (sessions, system-prompt, tools, agents, invariants, `agent-loop`) and the front-door cluster (JSONL persistence, the pi-tui channel, the pre-created `main` agent) live inside the [`@deepseek-ai/dsh-tui-demo`](../../packages/examples/tui-demo) app and the [`@deepseek-ai/dsh-agent-spine-demo`](../../packages/examples/agent-spine-demo) bundle it loads; the leaf wires the backends and model-facing optional tools:
-
-| Entry | Demonstrates |
-|---|---|
-| `hmr` (`@cordisjs/plugin-hmr`) | the dev/demo edit-reload loop — a **leaf** entry (not baked into the app) because it depends on the Loader's internal module access |
-| `llm-deepseek` | the default native adapter |
-| `bash` (`dsh-bash-local`) | the executor implementation — the swappable half of the bash seam. The model-facing `bash` schema (`tool-bash`) and generic `task_*` controls (`tool-tasks`) come from `dsh-agent-spine-demo`, so only the executor is a leaf choice |
-| `tui-agent` (`@deepseek-ai/dsh-tui-demo`) | the app bundle: the agent-spine demo + JSONL persistence + the pi-tui channel + a pre-created `main` agent |
-| `subagent`, `subagent-spawn`, `subagent-fork` | the subagent provider registry plus the two in-process backends: a fresh child and a child seeded with the parent's completed-turn prefix |
-| `tool-subagent`, `tool-subagent-fork` | two model-facing `dsh-tool-subagent` loads, each bound to a different provider and exposed under a distinct tool name (`subagent`, `subagent_fork`) |
-| `workflow-workerthread`, `tool-workflow` | the worker-thread workflow engine and its model-facing `workflow` tool, with child calls routed through the spawn backend |
-| `plan-mode` | the plugin-owned `/plan [message]` entry and `/plan off` exit commands, plan-mode prompt policy, tool restrictions, and reviewed `exit_plan_mode` transition |
-| `fs-local`, `fs-policy`, `tool-fs` | the filesystem stack: the local `ctx.fs` provider, the read-before-write/edit policy gate (on the `fs/*` event gate), and the model-facing `read`/`write`/`edit` tools. Relative paths resolve against the session workspace |
-
-## End-to-end tests (`pnpm run test:e2e`)
-
-The UI-independent with-key suites assemble the full stack programmatically through `tests/harness.ts` (no PTY, no Loader):
-
-- `tests/full-loop.e2e.ts` — the canary: real model runs `echo e2e-ok` through the real bash tool; asserts `tool/call`/`tool/result` session events and the final answer.
-- `tests/coding-task.e2e.ts` — the swebench-style smoke: a temp dir holds `add.js` (with `a - b` where `a + b` belongs) and a failing `add.test.js`; the agent must fix the bug and verify. The test re-runs `node add.test.js` ITSELF and inspects the files — agent claims are not trusted.
-- `tests/resume.e2e.ts` — durable continuity across processes: run 1 tells the real model a secret code and persists the turn to a temp JSONL root, then the whole context is disposed; run 2 is a fresh context over the same root that RESUMES the session id and asks the model to recall the code. The recall can only come from the rehydrated log.
-- `tests/compaction.e2e.ts` — the compaction smoke: a real multi-step bash task runs with a deliberately tiny context window so the auto-compaction listener fires MID-SESSION. Verifies the WORLD — a `compact/start…end` pair landed in the real log, the surface shrank (a replace node shadowed older nodes), and the agent still produced a correct final answer after compaction.
-- `tests/todo-write.e2e.ts` — loads the opt-in `todo_write` tool, then a real model drives it and the test verifies the resulting `todo/write` session event.
-- `tests/code-mode.e2e.ts` — the with-key Code Mode proof: a real model, a two-tool task, asserting the wire tool list was exactly `[run_code]`, the `tool/code-dispatch` events landed under the parent call, and the curated answer came back.
-
-These self-skip without `DEEPSEEK_API_KEY`. The keyless `tests/tui-keyless-smoke.e2e.ts` boots the real Loader tree in a PTY (the one sanctioned PTY surface): the base boot + `/plan` + `/exit`, a scripted-LLM conversation with a question dialog and tool round-trip, the Code Mode overlay welcome line, and the resume-failure exit path.
-
-## Snapshot tests
-
-`tests/snapshots/<scenario>/session.jsonl` supplies recorded user prompts and model chunks; sibling child logs drive subagents and workflows. The keyless suite executes those scripts through the real loop and tool implementations, then compares readable expected terminal cell/style output. Use `pnpm run test:snapshot:refresh` for presentation-only changes and `pnpm run test:snapshot:record` with a DeepSeek key when a recorded model journey changes. The implemented [TUI snapshot Agent Note](../../.agents/notes/implemented/testing/2026-07-18-tui-terminal-state-snapshots.md) owns the scenario matrix and the split between recorded journeys, transient package snapshots, and PTY coverage.

-          You are in plan mode. Stay in plan mode until exit_plan_mode succeeds or the user switches the session mode. Imperative language to implement changes means plan the implementation, not execute it. A user's conversational agreement — including an answer confirming something you asked — approves nothing and does not end plan mode; fold the confirmed decision into the plan and submit it through exit_plan_mode.
-
-          Explore first. Use non-mutating reads, searches, static analysis, and checks to ground the plan in the actual repository. Do not edit or write files, change configuration, run formatters or code generation that rewrites tracked files, commit, or otherwise carry out the plan. Prefer existing functions and patterns over new machinery.
-
-          The tool catalog stays the same across modes for request-cache stability. These plan-mode rules override any later tool description or guidance that suggests using mutation tools; those tools remain listed only to keep the request shape stable. Do not use todo_write to track this planning phase: it tracks implementation after an approved plan, while the plan itself belongs in exit_plan_mode.
-
-          Resolve discoverable facts by inspection. Use ask_user_question only for user-owned choices or material ambiguity that inspection cannot answer. Do not ask the user where code lives or how current behavior works when you can find out.
-
-          Make the plan decision-complete: state the goal and success criteria; group implementation changes by subsystem; identify public API, schema, and data-flow changes; cover edge cases, failure modes, tests, acceptance criteria, and explicit assumptions. Keep it concise enough to review but detailed enough that another engineer can implement it without making design decisions.
-
-          When ready, call exit_plan_mode with the complete plan markdown, starting with a # title. Make exit_plan_mode the only and final tool call in that assistant response: it presents the plan for approval, and implementation begins only in a later step after approval. Do not paste the final plan as a plain reply or ask "should I proceed?" through prose or ask_user_question. If review rejects it, incorporate the feedback and present again. If the review channel is unavailable or aborted, stay in plan mode and ask the user to switch modes manually; do not proceed with implementation.

 Bringing up a new `packages/client/<name>` plugin package (ui-workspace is the latest walked example; ui-sidebar/ui-question are good skeletons to copy):
 
 1. **Package skeleton**: `package.json` (`@deepseek-ai/dsh-client-<name>`, exports `.`/`./invariant`/`./client`/`./src/*`/`./package.json`, `dshClient` manifest, `files` list), `tsconfig.json` (extends `tsconfig.base.client.json`, one `references` entry per workspace dependency plus `support/invariants`), `tsdown.config.ts` (`clientBundle(id, ['lib/types/index.js', 'lib/types/invariant.js'])`), `src/index.ts` (empty node-half apply), `src/invariant.ts` (companion with a real reason), `src/css-modules.d.ts` when using CSS Modules, `README.md` with the Model Experience section.
-2. **Three registration surfaces, all required** (missing any one fails at a different, later point): the `tsconfig.client.json` aggregate `references` entry; a `dshClient` row in `apps/cli/cordis.yml`; an `apps/cli/package.json` dependency (Loader resolves each config-tree package against the composing app's URL — a row whose package is not an `apps/cli` dependency fails to import). `pnpm-workspace.yaml` already globs `packages/*/*`.

 3. **dshClient manifest semantics**: `platform: 'web'` always; `immediately: true` only for stage-one-prefetch infrastructure rows. `inject` lists package-name dependency edges — they are **informational only** (preflight display, HMR diffing); they do not sequence entry activation or apply order. Activation order is cordis fiber inject waiting on *services*, nothing else.
 4. **Registering into another package's slot**: if the declaring host provides no waitable service, your apply's order relative to the host's is unconstrained — a bare `slots.register` into its slot races boot (intermittent `slot "..." is not declared` page failures). Register with declaration-aware deferral: check `ctx.slots.spec(name)`, otherwise `ctx.slots.subscribe(name)` and register on the declaration event (SlotCore supports subscribing ahead of declaration); make the registration idempotent, and unsubscribe + dispose in the effect disposer. Only take a service edge in `inject` when the host actually provides one (ui-question → `'conversation'` is that case).
 5. Rebuild the bundle (`pnpm --filter <pkg> bundle`) before probing a live `dsh web` server — the registry serves `lib/client.js`, not sources.

-# @deepseek-ai/dsh-tui-demo
-
-English | [中文](README.zh.md)
-
-The full-screen terminal app bundle: a Cordis plugin that composes [`@deepseek-ai/dsh-agent-spine-demo`](../agent-spine-demo/README.md), persisted same-session goals, the human-command registry and `/goal` producer, JSONL persistence, keyboard-backed user interaction, a pre-created `main` agent, and [`@deepseek-ai/dsh-tui`](../../ui/tui/README.md). A `cordis.yml` mounts it as one entry; the [`dsh`](../../../apps/cli/README.md) CLI is the front door that boots such a config.
-
-Use [`@deepseek-ai/dsh-cli-demo`](../cli-demo/README.md) for pipes, scripts, and other non-interactive runs. This bundle requires a TTY pair and has no line-oriented fallback.
-
-## What it bakes in
-
-| Plugin | Why it is here |
-|---|---|
-| `@deepseek-ai/dsh-agent-spine-demo` | Shared services, model-facing tools, and one configured `main` agent |
-| `@deepseek-ai/dsh-commands` | Human-only discovery and dispatch consumed by the TUI and command plugins |
-| `@deepseek-ai/dsh-command-goal` | Direct `/goal` status and mutation over the spine's persisted-goal stack |
-| `@deepseek-ai/dsh-session-persistence-jsonl` | Durable session log under `persistenceRoot` |
-| `@deepseek-ai/dsh-session-checkpoint-policy` | Semantic durability barriers before model requests and top-level tool effects, plus completed-step checkpoints |
-| `@deepseek-ai/dsh-session-query-sqlite` + `@deepseek-ai/dsh-session-reference` | Combined exact/FTS session queries and bounded `@session` snapshots consumed by the TUI; model-facing query tools remain a leaf opt-in |
-| `@deepseek-ai/dsh-user-interaction` | Provider-neutral human question service |
-| `@deepseek-ai/dsh-tui` | Full-screen transcript, editor, tool cards, plan, and question overlays |
-| `@deepseek-ai/dsh-tool-ask-user` | Model-facing `ask_user_question` tool |
-
-Swappable LLM, bash, filesystem, and other capability providers remain in the leaf config. `@cordisjs/plugin-hmr` also remains a leaf-only development entry because it requires Loader internals.
-
-## Config
-
-| Key | Default | Routed to |
-|---|---|---|
-| `provider` | required | Configured `main` agent provider |
-| `model` | required | Configured `main` agent model |
-| `maxParallelToolCalls` | agent-loop default | Bundled loop concurrency cap |
-| `persona` | — | System-prompt persona template |
-| `toolOrder` | lexicographic | Explicit model-facing tool order |
-| `tools` | owner default | Tool presentation mode |
-| `dshHome` | owner default | Harness home used by bash and skills |
-| `sessionTitle` | spine example limits | Fallback title word/byte limits |
-| `skills` | owner defaults | Skill registry, local provider, and tool config |
-| `toolBash` | owner defaults | Model-facing bash tool config |
-| `toolTasks` | owner defaults | Background-task control-tool config, or `false` |
-| `goals` | owner defaults | Persisted goal-domain and model-tool config; `false` removes the goal stack and `/goal` producer |
-| `workspaceContext` | required | Workspace-instruction config, or `false` |
-| `persistenceRoot` | `./.sessions` (launcher boot slot overrides) | JSONL persistence root and parent of the derived `session-query.db` index |
-| `persistenceCompression` | `'zstd'` | JSONL artifact encoding (`'zstd'` or raw `'none'`) |
-| `sessionReferences` | service defaults | Cross-session candidate and snapshot limits routed to `dsh-session-reference` |
-| `welcome` | `ready.` | TUI subtitle |
-| `ui` | owner defaults | TUI presentation settings such as reasoning, color, and card height |
-
-Session identity is launcher-owned rather than configurable: a launcher provides `MAIN_SESSION_ID_KEY` on the boot context, and this app binds both the TUI and the configured agent to that id, loading persisted history only when the launcher also set `resume`. With no such slot the app mints a `main-session-<uuid>` and creates it fresh. The TUI mounts before the spine so it can render a matching config-start failure instead of leaving a blank terminal. The app composes persistence and session query for `/resume`; a launcher may additionally provide `tuiResumeHost` for in-place process handoff and `TUI_GOODBYE_MESSAGE_KEY` for the line printed on exit.
-
-`persistenceRoot` defaults to project-local `./.sessions`: an app bundle must not assume the user's shared session store. A launcher that wants one store across every cwd states that policy through the `SESSIONS_ROOT_KEY` boot slot (`ctx.provide` before any Loader entry mounts) — the dsh CLI provides its Harness-home root there, so its `/resume` lists sessions from every workspace. Precedence is explicit config, then the launcher slot, then the project-local default.
-
-## Front door
-
-This package ships no bin. The [`dsh`](../../../apps/cli/README.md) CLI is the terminal front door: bare `dsh` boots the shipped `examples/tui-agent/cordis.yml` (which mounts this bundle), and `dsh --config <path-to-cordis.yml>` boots an alternate leaf config that mounts it. It loads the optional cwd `.env`, drives the Cordis Loader, and waits for the full plugin tree. The repository installs Loader's optional native helper, so bare package specifiers resolve under plain Node.
-
-## Example leaf
-
-```yaml
-- id: llm-deepseek
-  name: '@deepseek-ai/dsh-llm-deepseek'
-  config:
-    apiKey: !!js process.env.DEEPSEEK_API_KEY
-- id: bash
-  name: '@deepseek-ai/dsh-bash-local'
-- id: tui-agent
-  name: '@deepseek-ai/dsh-tui-demo'
-  config:
-    provider: deepseek
-    model: deepseek-v4-flash
-    workspaceContext:
-      maxBytes: 65536
-    welcome: 'Coding agent ready.'
-    ui:
-      showReasoning: true
-```
-
-## Model Experience
-
-### Interactive terminal turn
-
-#### What the model sees
-
-Each non-empty non-command editor submission becomes a user message; a submission during a running turn becomes steering. Slash-command input and output remain human-only, while accepted `/goal` mutations append domain-owned model-visible state. The shared spine contributes the configured persona, workspace instructions, skill catalog, goal controls, and visible tool schemas. TUI rendering itself is not model-visible.
-
-#### Token effect
-
-User, assistant, and tool history grows under the normal session and compaction rules. Headers, cards, plans, Markdown styling, and keybindings add no tokens.
-
-#### KV Cache effect
-
-Append-only while the composed prompt, schemas, route, and retained history prefix remain stable. Composition changes and compaction can invalidate reuse from the first changed token.
-
-### Human-question answer
-
-#### What the model sees
-
-`ask_user_question` retains the tool call and the compact answer or stable interruption error defined by `dsh-tool-ask-user`. The question overlay is terminal-only.
-
-#### Token effect
-
-Only the completed or failed tool result adds retained tokens.
-
-#### KV Cache effect
-
-Append-only; the answer follows the reusable request prefix.
-
-## Known Limitations and Deferred Work
-
-- **TTY-only** — stdin and stdout must both be terminals; automation uses `dsh-cli-demo`.
-- **One configured terminal session** — the transcript and editor bind to one exact session id.
-- **The app cluster is fixed** — JSONL persistence and ask-user tooling are baked in; different policy requires another composition.
-- **Approval is separate** — this app answers `ctx.userInteraction`, not `ctx.approval`; permission prompts require an approval service and answerer.

CI covers 22.19, 24, and 26; see the [Node engine floor Agent Note](../.agents/notes/implemented/process/2026-07-06-node-engine-floor.md).\n- Corepack-enabled pnpm. The repo pins `pnpm@11.7.0` in `package.json`; run `corepack enable` if `pnpm --version` does not resolve through Corepack.\n- Git 2.26 or newer; hook setup enables Git's worktree-specific configuration extension.\n- Optional: a DeepSeek API key for the TUI, headless, and ACP automation demos and real-API e2e tests.\n\n## First-time setup\n\nInstall dependencies from the repo root:\n\n```sh\npnpm install\n```\n\nThe install also runs the root `postinstall` script, which installs lefthook from the repo dev dependency through `scripts/install-lefthook.mjs`. With `CI=true` or `GITHUB_ACTIONS=true`, the wrapper returns before Git discovery because automated jobs do not consume contributor hooks. Otherwise, it requires Git 2.26 or newer and gives the current worktree an explicit hook directory under its own Git directory; linked worktrees therefore use their own lefthook binary and configuration instead of rewriting common hooks. The first install enables Git's worktree-specific configuration extension and repository format 1; see the [worktree-local hooks Agent Note](../.agents/notes/implemented/process/2026-07-27-worktree-local-lefthook.md).\n\nIf hooks are missing because dependencies were restored from cache or `postinstall` was skipped, install them manually:\n\n```sh\nnode scripts/install-lefthook.mjs\n```\n\nThe wrapper refuses user-owned `core.hooksPath` values. An inherited system, global, or common-repository path requires `DSH_LEFTHOOK_ALLOW_HOOKS_PATH_OVERRIDE=1`. When Git seeds a new worktree with another registered worktree's marker-backed hook path, the wrapper replaces that copied value with the new worktree's own path; command-scoped and other worktree-scoped paths must be integrated or removed explicitly.\n\nBefore enabling worktree config, migrate direct `extensions.*` in a format-0 common config, direct `core.worktree` or `core.bare=true`, and any non-empty dormant `config.worktree`. The common config and every worktree config must be regular files, while the owned hook directory may contain only unaliased regular files.\n\nAfter moving a checkout, rerun the wrapper to relocate its owned path and regenerate hooks. For a stale or invalid installer lock, first confirm no installer is running, then remove the reported lock and retry. If installation and hook-path rollback both fail, inspect the reported worktree config before retrying. The [worktree-local hooks Agent Note](../.agents/notes/implemented/process/2026-07-27-worktree-local-lefthook.md) owns the full safety contract.\n\nRun typecheck once after a fresh clone:\n\n```sh\npnpm run typecheck\n```\n\nThat first typecheck runs the whole-repo `tsc -b` graph: it emits every package/vendor `lib/types` and checks examples, tests, and scripts through the two no-emit aggregates described below.\n\n## TypeScript project layout\n\nThe repository's TypeScript configuration has exactly three roles; every tsconfig file plays one of them.\n\n| File | Role | Forms a program? |\n|---|---|---|\n| `tsconfig.json` | Solution root: `extends` base, `files: []`, references to the two aggregates. The whole-repo `tsc -b tsconfig.json` graph, the tsserver discovery entry, and — through the inherited `paths` — the resolution config for tsx running `examples/` and `scripts/` (their nearest tsconfig is this file). | No |\n| `tsconfig.host.json` | Host aggregate: host-side packages (via references), examples, tests, scripts, website. Excludes `packages/client`. | Yes |\n| `tsconfig.client.json` | Client aggregate: `packages/client/*` packages and their tests, `apps/web`. | Yes |\n| `tsconfig.base.json` | Shared compilerOptions and the source `paths` map. Also the resolution facade the vitest configs point vite-tsconfig-paths at: it has no `include`, so its `paths` apply to every importer. | No |\n| `tsconfig.base.client.json` | Browser compiler shape (`jsx`, DOM libs, `types: []`) extended by the client aggregate and every `packages/client/*` package. | No |\n\nHost and client stay two aggregate programs because both sides declaration-merge the cordis `Context` interface under the same keys with different services; one program seeing both merges reports a collision. The collision exists only inside a `ts.Program` — module resolution never triggers it — which is why the solution may reference both aggregates and one paths facade may span both sides. Two disciplines follow:\n\n- `tsconfig.base.json` never gains `include` or `files`: they would leak into every extending package project and narrow the facade's match-all scope.\n- A script that builds a repo-wide `ts.Program` seeds `tsconfig.host.json` or `tsconfig.client.json` explicitly — never the root solution, because flattening both aggregates into one program collides the `Context` merges. Program-backed generators and gates (`scripts/ts-project.ts` consumers, doc-typecheck standalone mode) are host-only by decision; the client side gains program-backed tooling only with a concrete need.\n\nStatic analysis and tests resolve workspace imports through the base `paths` map to `src` and must pass on a clean tree; gates that consume built `lib/` output declare that dependency explicitly. Decision record: [solution-root note](../.agents/notes/implemented/process/2026-07-22-tsconfig-solution-root-two-aggregates.md); the tsc-first emit pipeline is the [ts-build-config note](../.agents/notes/implemented/process/2026-06-17-ts-build-config.md).\n\nIf a relevant local check consumes built package output, build once first:\n\n```sh\npnpm run build\n```\n\n`pnpm run hygiene` includes `publint`, which validates package entrypoints against the built `lib/*.js` files, and `verify-node-next-types`, which validates built declarations against a temporary NodeNext consumer. A fresh worktree has no bundled JS or declarations until `pnpm run build` runs; ordinary commits and pushes do not require that build unless their selected checks consume it.\n\n## Environment variables\n\nThe real DeepSeek adapter and key-backed agent demos read credentials from the environment or from a gitignored `.env` at the repo root:\n\n```sh\nDEEPSEEK_API_KEY=sk-...\nDEEPSEEK_BASE_URL=https://... # optional\n```\n\n`DEEPSEEK_BASE_URL` is optional and defaults to the public API. Never commit real credentials. The real-API e2e suites self-skip when `DEEPSEEK_API_KEY` is not set.\n\n## Git hooks\n\nlefthook is configured in `lefthook.yml` as a fast local checkpoint:\n\n- `pre-commit` runs staged-file ESLint fixes, checks the staged diff for whitespace errors, and runs the vendor manifest guard.\n- `pre-push` runs only the incremental repository typecheck (`tsc -b` over the root solution, covering both the host and client aggregates).\n\nThe vendor manifest guard checks that changes under `vendor/*/src` are staged with the matching `vendor/README.md` manifest update. See `vendor/README.md` before editing vendored code.\n\nThe hooks intentionally do not run tests, snapshots, documentation checks, builds, or hygiene. Contributors run the [checks relevant to the changed behavior](../AGENTS.md#run-relevant-checks-locally) once; CI owns exhaustive coverage, built-artifact smokes, and the Node 22.19, 24, and 26 compatibility matrix.\n\nContributors can opt into the comprehensive local gate set with `pnpm run check:all`. The command is independent of both Git hooks and is not an agent instruction.\n\n## CI gates\n\nThe keyless [CI workflow](../.github/workflows/ci.yml) groups independent gates into broad lanes and runs a smaller compatibility signal across supported Node versions. Artifact consumers wait for one build within their lane. The separate real-API workflow runs `pnpm run test:e2e` with its configured worker bound. See [scripts/run-gates.ts](../scripts/run-gates.ts) and the workflow files for the current gate and job inventory.\n\n## Daily commands\n\nUse these from the repo root:\n\n```sh\npnpm run test           # unit tests\npnpm run test:coverage  # unit tests with per-file coverage gates\npnpm run test:e2e       # real-API tests; self-skips without DEEPSEEK_API_KEY\npnpm run check:all      # comprehensive opt-in gate set; not wired to Git hooks\npnpm run typecheck      # tsc -b over the root solution: emits package/vendor lib/types, checks both aggregates\npnpm run lint           # eslint .\npnpm run lint:fix       # eslint . --fix\npnpm run doc-typecheck  # compile checked TypeScript snippets in Markdown docs\npnpm run gen-cordis-catalog     # regenerate docs/cordis-catalog/events.md + services.md from source\npnpm run verify-cordis-catalog  # fail if either cordis catalog is stale\npnpm run verify-export-jsdoc    # fail if a module-level package export lacks complete JSDoc\npnpm run gen-doc-graphs     # regenerate generated relationship docs from source and curated graph definitions\npnpm run verify-doc-graphs  # fail if generated relationship docs are stale\npnpm run verify-md-wrap  # fail on hard-wrapped prose paragraphs in docs/README markdown\npnpm run verify-mermaid  # fail if a ```mermaid diagram has invalid Mermaid syntax\npnpm run verify-type-equiv  # fail if a ```ts type-equiv doc block drifts from its source type\npnpm run verify-doc-budgets  # fail if a budgeted standing doc exceeds its word ceiling\npnpm run gen-translation-brief   # print the minimal-update briefing for out-of-sync translation pairs (--apply splices code-only edits)\npnpm run doc-sync       # all Markdown/doc gates, scheduled concurrently; the doc-sync leaf list in scripts/run-gates.ts is the full list\npnpm run gen-module-graph     # regenerate docs/module-graph.md from package peerDeps\npnpm run verify-module-graph  # fail if docs/module-graph.md is stale\npnpm run build          # emit lib/types intermediates, then bundle lib/index.* runtime files\npnpm run verify-node-next-types  # fail if built declarations are not NodeNext-consumable\npnpm run hygiene        # knip, publint, workspace constraints, and NodeNext declaration check\n```\n\nWhen changing package public behavior, update the relevant README or JSDoc in the same change. `pnpm run doc-sync` catches checked TypeScript snippets, generated doc freshness, markdown wrap/link drift, type equivalence, translation pairing, Mermaid syntax, and doc budgets, but broader prose/API sync still needs review.\n\n## Demos\n\nThe one-shot Headless coding agent needs `DEEPSEEK_API_KEY` in the environment or repo-root `.env`:\n\n```sh\npnpm run demo:headless \"summarize this workspace\"\n```\n\nThe full-screen interactive coding agent needs `DEEPSEEK_API_KEY` in the environment or repo-root `.env`:\n\n```sh\npnpm run demo:tui\n```\n\nThe self-referential cordis-agent demo can inspect and modify its live plugin runtime and needs the same credentials:\n\n```sh\npnpm run demo:cordis\n```\n\nThe ACP automation server exposes fresh agent sessions over JSON-RPC stdio and also needs `DEEPSEEK_API_KEY`:\n\n```sh\npnpm run demo:acp\n```\n\n## TODO markers\n\nUse one of three comment tags to flag known issues in the code, ordered by urgency:\n\n- `FIXME` — an issue that should block a new release. A release should not ship with an open `FIXME` unless reviewers explicitly agree the change can be merged anyway.\n- `TODO` — an issue that should be fixed soon, once we have the resources.\n- `XXX` — an issue that we may fix someday; lowest priority, no commitment.\n\nPick the tag that matches the urgency so anyone scanning the code can tell a release blocker from a someday-maybe.\n\n## Documenting types verbatim (`ts type-equiv`)\n\nThe [core data structures](core-data-structures/core.md) docs paste source-equivalent declarations together with their original JSDoc so a reader sees the exact shape and source contract. To keep a paste from drifting when source changes, fence it as ` ```ts type-equiv ` (instead of ` ```ts `) and register it in `scripts/type-equiv.manifest.json` with the source file and symbol it mirrors:\n\n```json\n{ \"doc\": \"docs/core-data-structures/session.md\", \"symbol\": \"SessionEvent\", \"source\": \"packages/core/session/src/types.ts\" }\n```\n\n`pnpm run verify-type-equiv` (part of `doc-sync`) then extracts that symbol's declaration and attached JSDoc from source via the TypeScript parser and asserts the block matches both. For a class whose implementation bodies do not belong in the catalog, use ` ```ts public-api ` and set `\"projection\": \"public-api\"`; the checked projection retains the public fields, constructor, accessors, methods, and original class/member JSDoc while omitting bodies and private or protected members. Comparison ignores whitespace and non-JSDoc comments but requires every original JSDoc comment, including member documentation, so readers see the source contract beside the exact shape. The gate enforces a 1:1 correspondence by document, symbol, and projection between primary blocks and manifest entries; a paired `.zh.md` block reuses its unsuffixed sibling's entry only when the whole tracked fence sequence is byte-identical and ordered identically. `doc-typecheck` applies the same derivative rule to compilable fences, while skipping both source-equivalence fence kinds from compilation and its opt-out ratio. When you change a documented declaration or its JSDoc, the gate fails until you update the paste; when you add or remove a primary block, update the manifest in the same change.\n\n## Architecture context\n\nRead `docs/architecture.md` before changing anything under `packages/`. The codebase is built around Cordis plugins, event-sourced sessions, typed service seams, and explicit extension points.\n"

-        "content": "# 开发指南\n\n[English](development.md) | 中文\n\n本指南覆盖参与 DeepSeek Harness 开发所需的本地环境搭建、日常工作流与 CI 流程；设计动机与技术权衡请查阅相应 Agent Note。\n\n## 前置条件\n\n- Node.js 支持 22.19+ 与 24+。CI 覆盖 22.19、24 和 26；见 [Node 引擎下限 Agent Note](../.agents/notes/implemented/process/2026-07-06-node-engine-floor.md)。\n- 启用了 Corepack 的 pnpm。仓库在 `package.json` 中固定使用 `pnpm@11.7.0`；如果 `pnpm --version` 无法通过 Corepack 解析，请先运行 `corepack enable`。\n- Git 2.26 或更高版本；钩子设置会启用 Git 的 worktree 专属配置扩展。\n- 可选：一个 DeepSeek API key，用于 TUI、headless 和 ACP（Agent Client Protocol）自动化 agent（智能体）演示以及真实 API 的 e2e 测试。\n\n## 首次搭建\n\n在仓库根目录安装依赖：\n\n```sh\npnpm install\n```\n\n安装过程同时会运行根目录的 `postinstall` 脚本，该脚本通过 `scripts/install-lefthook.mjs` 从仓库 dev 依赖安装 lefthook。当 `CI=true` 或 `GITHUB_ACTIONS=true` 时，该脚本会在探测 Git 前返回，因为自动化任务不会使用贡献者钩子。否则，包装脚本要求使用 Git 2.26 或更高版本，并会为当前 worktree 在其自身的 Git 目录下设置显式钩子目录；因此，关联 worktree 会使用各自的 lefthook 二进制文件和配置，而不会改写共用钩子。首次安装会启用 Git 的 worktree 专属配置扩展和仓库格式 1；见 [worktree 本地钩子 Agent Note](../.agents/notes/implemented/process/2026-07-27-worktree-local-lefthook.md)。\n\n如果依赖是从缓存恢复或 `postinstall` 被跳过而导致缺少钩子，请手动安装：\n\n```sh\nnode scripts/install-lefthook.mjs\n```\n\n包装层会拒绝用户自有的 `core.hooksPath` 值。继承自系统、全局或共用仓库配置的路径必须设置 `DSH_LEFTHOOK_ALLOW_HOOKS_PATH_OVERRIDE=1`。当 Git 使用另一个已注册 worktree 中由所有权标记佐证的钩子路径初始化新 worktree 时，包装层会将这个复制值替换为新 worktree 自有的路径；命令作用域和其他 worktree 作用域的路径必须显式集成或移除。\n\n启用 worktree 配置之前，请迁移格式 0 共用配置中直接设置的 `extensions.*`，并迁移直接设置的 `core.worktree` 或 `core.bare=true`，以及任何非空且尚未生效的 `config.worktree`。共用配置和每个 worktree 配置都必须是常规文件，而自有钩子目录只能包含不带别名的常规文件。\n\n检出目录移动后，请重新运行包装层，使其重新定位自有路径并重新生成钩子。对于陈旧或无效的安装程序锁，请先确认没有安装程序正在运行，再移除报告的锁并重试。若安装和钩子路径回滚都失败，请在重试前检查报告的 worktree 配置。完整安全契约由 [worktree 本地钩子 Agent Note](../.agents/notes/implemented/process/2026-07-27-worktree-local-lefthook.md) 统一定义。\n\n新克隆后请先运行一次类型检查：\n\n```sh\npnpm run typecheck\n```\n\n首次类型检查会执行全仓 `tsc -b tsconfig.json` 图：发射每个 package/vendor 的 `lib/types`，并通过下述两个 no-emit 聚合检查示例、测试和脚本。\n\n## TypeScript 项目布局\n\n仓库的 TypeScript 配置只有三种角色；每个 tsconfig 文件恰好扮演其中一种。\n\n| 文件 | 角色 | 是否构成 program？ |\n|---|---|---|\n| `tsconfig.json` | solution 根：`extends` base、`files: []`、引用两个聚合。全仓 `tsc -b tsconfig.json` 图、tsserver 发现入口，并经继承的 `paths` 充当 tsx 运行 `examples/` 与 `scripts/` 时的解析配置（它们最近的 tsconfig 就是此文件）。 | 否 |\n| `tsconfig.host.json` | host 聚合：host 侧各包（经 references）、示例、测试、脚本、website。排除 `packages/client`。 | 是 |\n| `tsconfig.client.json` | client 聚合：`packages/client/*` 各包及其测试、`apps/web`。 | 是 |\n| `tsconfig.base.json` | 共享 compilerOptions 与源码 `paths` 映射。同时是各 vitest 配置让 vite-tsconfig-paths 指向的解析门面：它没有 `include`，因此其 `paths` 适用于任何 importer。 | 否 |\n| `tsconfig.base.client.json` | 浏览器编译形状（`jsx`、DOM lib、`types: []`），由 client 聚合和每个 `packages/client/*` 包 extends。 | 否 |\n\nhost 与 client 保持两个聚合 program，是因为两侧在相同键下以不同服务对 cordis `Context` 接口做声明合并；单一 program 同时看到两份合并会报冲突。这种冲突只存在于 `ts.Program` 内部——模块解析永远不会触发它——所以 solution 可以同时引用两个聚合，一个 paths 门面也可以横跨两侧。由此推出两条纪律：\n\n- `tsconfig.base.json` 永不添加 `include` 或 `files`：它们会泄漏进每个 extends 它的包项目，并收窄门面的全匹配范围。\n- 构造全仓 `ts.Program` 的脚本显式种子 `tsconfig.host.json` 或 `tsconfig.client.json`——永不种子根 solution，因为把两个聚合展平进一个 program 会撞上 `Context` 合并冲突。基于 program 的生成器与门禁（`scripts/ts-project.ts` 的消费者、doc-typecheck standalone 模式）按决策仅覆盖 host 侧；client 侧只在出现真实需求时再获得基于 program 的工具。\n\n静态分析和测试通过 base 的 `paths` 映射把工作区 import 解析到 `src`，且必须在干净树上通过；消费构建产物 `lib/` 的门禁显式声明该依赖。决策记录：[solution-root note](../.agents/notes/implemented/process/2026-07-22-tsconfig-solution-root-two-aggregates.md)；tsc-first 发射管线见 [ts-build-config note](../.agents/notes/implemented/process/2026-06-17-ts-build-config.md)。\n\n如果相关的本地检查需要使用构建后的包产物，请先构建一次：\n\n```sh\npnpm run build\n```\n\n`pnpm run hygiene` 包含 `publint`（用构建出的 `lib/*.js` 文件校验 package 入口点）和 `verify-node-next-types`（用一个临时的 NodeNext 消费方校验构建出的声明文件）。新 worktree 在 `pnpm run build` 运行之前没有打包的 JS 和声明文件；普通提交和推送无需构建，除非所选检查会使用这些产物。\n\n## 环境变量\n\n真实的 DeepSeek 适配器和需要密钥的 agent 演示从环境变量或仓库根目录一个被 gitignore 的 `.env` 文件读取凭证：\n\n```sh\nDEEPSEEK_API_KEY=sk-...\nDEEPSEEK_BASE_URL=https://... # optional\n```\n\n`DEEPSEEK_BASE_URL` 可选，默认为公开 API。请勿提交真实凭证。未设置 `DEEPSEEK_API_KEY` 时，真实 API 的 e2e 套件会自动跳过。\n\n## Git 钩子\n\nlefthook 在 `lefthook.yml` 中配置，作为快速的本地检查点：\n\n- `pre-commit` 运行对暂存文件的 ESLint 修复，检查暂存 diff 中的空白错误，并运行 vendor manifest（元数据清单）守卫；\n- `pre-push` 只运行仓库增量类型检查（对根 solution 执行 `tsc -b`，覆盖 host 与 client 两个聚合）。\n\nvendor manifest 守卫检查 `vendor/*/src` 下的改动是否连同对应的 `vendor/README.md` manifest 更新一起暂存。请在编辑 vendor 代码前先阅读 `vendor/README.md`。\n\n这些钩子有意不运行测试、快照、文档检查、构建或 `hygiene`。贡献者只运行一次[与改动行为相关的检查](../AGENTS.md#run-relevant-checks-locally)；CI 负责全量覆盖率门禁、构建产物冒烟测试，以及 Node 22.19、24 和 26 兼容性矩阵。\n\n贡献者可以选择运行 `pnpm run check:all`，执行全面的本地门禁集。该命令独立于两个 Git 钩子，也不是对 agent 的指令。\n\n## CI 门禁\n\nkeyless [CI 工作流](../.github/workflows/ci.yml) 将独立门禁分组到若干宽粒度 lane，并在受支持的 Node 版本上运行一组较小的兼容性检查。产物消费方在各自 lane 内等待一次 build。单独的真实 API 工作流按其配置的 worker 上限运行 `pnpm run test:e2e`。当前门禁和 job 清单以 [scripts/run-gates.ts](../scripts/run-gates.ts) 和工作流文件为准。\n\n## 日常命令\n\n在仓库根目录使用：\n\n```sh\npnpm run test           # unit tests\npnpm run test:coverage  # unit tests with per-file coverage gates\npnpm run test:e2e       # real-API tests; self-skips without DEEPSEEK_API_KEY\npnpm run check:all      # comprehensive opt-in gate set; not wired to Git hooks\npnpm run typecheck      #

regenerate docs/module-graph.md from package peerDeps\npnpm run verify-module-graph  # fail if docs/module-graph.md is stale\npnpm run build          # emit lib/types intermediates, then bundle lib/index.* runtime files\npnpm run verify-node-next-types  # fail if built declarations are not NodeNext-consumable\npnpm run hygiene        # knip, publint, workspace constraints, and NodeNext declaration check\n```\n\n修改 package 的公开行为时，请在同一个变更中更新相关 README 或 JSDoc。`pnpm run doc-sync` 能检测到被检查的 TypeScript 片段、生成文档的新鲜度、Markdown 换行/链接漂移、type-equiv、翻译配对、Mermaid 语法和文档预算，但更广泛的行文/API 同步仍需评审把关。\n\n## 演示\n\n单次运行的 Headless coding agent 需要环境变量或仓库根目录 `.env` 中的 `DEEPSEEK_API_KEY`：\n\n```sh\npnpm run demo:headless \"summarize this workspace\"\n```\n\n全屏交互式 coding agent 需要环境变量或仓库根目录 `.env` 中的 `DEEPSEEK_API_KEY`：\n\n```sh\npnpm run demo:tui\n```\n\n自指的 cordis-agent 演示可以检查并修改其实时插件运行时，并需要相同的凭证：\n\n```sh\npnpm run demo:cordis\n```\n\nACP 自动化服务器通过 JSON-RPC stdio 提供全新 agent 会话，同样需要 `DEEPSEEK_API_KEY`：\n\n```sh\npnpm run demo:acp\n```\n\n## TODO 标记\n\n请使用以下三种注释标签之一标记代码中的已知问题，按紧急程度排序：\n\n- `FIXME`：应当阻塞新版本发布的问题。除非评审者明确同意该更改可以合并，否则发布版本不应包含未解决的 `FIXME`；\n- `TODO`：应当尽快修复的问题，等资源到位即可处理；\n- `XXX`：也许某天会修复的问题，优先级最低，不作承诺。\n\n请选择与紧急程度匹配的标签，让浏览代码的人一眼分清「发布阻塞」和「有空再说」。\n\n## 逐字记录类型（`ts type-equiv`）\n\n[核心数据结构](core-data-structures/core.md)文档会把与源码等价的声明及其原始 JSDoc 一并粘贴，让读者看到确切形状和源码契约。为防止粘贴内容在源码变化时漂移，请将其围栏为 ` ```ts type-equiv `（而不是 ` ```ts `），并在 `scripts/type-equiv.manifest.json` 中登记它镜像的源文件和符号：\n\n```json\n{ \"doc\": \"docs/core-data-structures/session.md\", \"symbol\": \"SessionEvent\", \"source\": \"packages/core/session/src/types.ts\" }\n```\n\n`pnpm run verify-type-equiv`（`doc-sync` 的一环）随后通过 TypeScript 解析器从源码提取该符号的声明及其附带的 JSDoc，并断言代码块同时匹配两者。对于不应把实现体写进目录的类，请使用 ` ```ts public-api ` 并设置 `\"projection\": \"public-api\"`；门禁检查的投影会保留公共字段、构造函数、访问器、方法以及类和成员的原始 JSDoc，同时省略实现体和私有或受保护成员。比对会忽略空白和非 JSDoc 注释，但要求保留每条原始 JSDoc（包括成员文档），让读者同时看到源码契约和确切形状。该门禁按文档、符号和投影，在主块与 manifest 条目之间强制 1:1 对应；只有当配对 `.zh.md` 块的完整受跟踪围栏序列与其无后缀兄弟文件按字节一致且顺序相同时，才会复用后者的条目。`doc-typecheck` 对可编译围栏应用同一派生规则，同时跳过两种源码等价围栏的编译，并将其排除在 opt-out 比例之外。当你改动一个已记录的类型声明或其 JSDoc 时，门禁会失败直到你更新粘贴内容；当你增删一个主块时，请在同一个变更里更新 manifest。\n\n## 架构上下文\n\n在修改 `packages/` 目录下的任何内容之前，请先阅读 `docs/architecture.md`。这套代码围绕 Cordis 插件、事件溯源的会话、类型化的服务 seam 与显式扩展点构建。\n"

@@ -37,7 +37,7 @@ Keep this log exhaustive — every divergence from upstream must be listed.
 5. **`schemastery/tsdown.config.ts` and `logger-console/tsdown.config.ts`**: ours, not upstream files — per-package build-shape overrides (dual ESM+CJS output; separate node/browser entries) for the repo-root tsdown build. They read the JS emitted under `lib/types` and then write the publish runtime entries under `lib/`. Like the regenerated tsconfigs, they are not part of the upstream sync surface.
 6. **`cordis/src/fiber.ts` lifecycle hardening**: locally closes three reentrant disposal gaps. An effect's owner-list wrapper is registered before its setup body runs, so an unload begun from inside setup awaits setup and every collected cleanup; synchronous setup failure removes the wrapper and rolls back collected cleanup. Async cleanup stays owner-visible until quiescence, and Cordis's internal effect composition joins an already-running cleanup while repeated public disposer calls retain their upstream single-shot result. Effect creation is rejected while the owner is `UNLOADING` (while `PENDING` and `LOADING` remain legal), preventing cleanup-time registrations from escaping the unload snapshot. Child fibers register and receive their parent-owned disposer before `internal/plugin` publication, resolve dependency declarations added by that notification before activation, drain effects attached while pending, skip plugin execution when reentrant disposal invalidates the load epoch before its first checkpoint, and contain teardown-notification failures per observer so one callback cannot starve peers or interrupt ownership cleanup.
 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). Covered by `packages/ui/app-boot/tests/config-reload.spec.ts`.

That matters because `dsh` composes one shared base (`apps/cli/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.

Subject: [PATCH 039/212] fix(cli): declare every plugin the shipped config
 trees name

The Loader resolves each config row against the composing app, so moving the
TUI composition from examples/ into apps/cli left eleven rows unresolvable from
the built bin: `node apps/cli/lib/bin.js` died at boot with "plugin(s) failed to
load". Source-mode runs hid it, because tsconfig paths resolve the whole
workspace regardless of who declares what.

Also declares `dsh-llm-pi-ai` and `dsh-tmux-context`, which a personal
`~/.dsh/config.yaml` inserts to swap the model adapter. Those previously
resolved only because the config lived under examples/, whose package.json
declares the union of every leaf's plugins.

Caught by running the built bin from a scratch directory, which is how a user
actually starts it.

-The `dsh` command-line entry follows the `apps/` assembly tier: `apps/*` are product assemblies over `packages/*` libraries. Plain `dsh` boots the interactive TUI coding agent, `dsh -p "task"` runs one headless turn, `dsh meta` boots that same TUI over this harness checkout, `dsh migrate` and `dsh upgrade` boot a fresh guided TUI session whose first turn invokes a bundled skill, `dsh list-sessions` lists the sessions running right now, and `dsh web` serves the browser UI.
 
-Argv is parsed once through a [Commander](https://github.com/tj/commander.js) adapter ([`src/args.ts`](src/args.ts)): one program whose default (no subcommand) is the TUI/headless surface (`--config`, `-p`/`--prompt`, `--resume`), whose `meta` subcommand is the same TUI over this checkout, whose `migrate`/`upgrade` subcommands are option-less guided-session entries, whose `list-sessions` subcommand (alias `ps`) lists live sessions, and whose `web` subcommand is the browser UI. `src/bin.ts` switches on the resolved mode and dynamic-imports only that mode's module. `dsh --help` lists every mode and `dsh web --help` renders the web usage, `dsh --version` prints this app's version, and an unknown option or a mistyped `--resume` fails loud (stderr, exit 1) instead of misrouting. Every subcommand that shares no option with the default surface — `migrate`, `upgrade`, `list-sessions`, `web` — rejects a leaked `--config`/`-p`/`--resume` rather than running and dropping it. `dsh web`'s `--host`/`--port` are unvalidated pass-through overrides: the `dsh-host-webserver` schema is the single source of both the default (the shipped `cordis.yml` value when a flag is absent) and validity, and rejects a bad value at boot. `--trusted-host` appends named authorities for the /api browser-trust fence; an all-interfaces bind additionally derives the machine's LAN IP literals itself ([`src/app-cli-entry.ts`](src/app-cli-entry.ts)), so the printed LAN URL works without flags.

 The TUI surface:
 
@@ -18,7 +17,6 @@ The TUI surface:
 
 `dsh migrate` and `dsh upgrade` are guided fresh-session entries over the default TUI surface: each mints a fresh session in the invoking directory and seeds its first turn with a bundled skill (`dsh-migrate` for migrating from another coding agent — opencode, pi, Claude Code, Codex; `dsh-upgrade` for upgrading this checkout), exactly as if the user typed `/skill:<name>`. 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 <id>` of the session is an ordinary TUI session with no re-injection.
 
-`dsh list-sessions` lists the sessions running right now: session id, pid, uptime, workspace, and title, newest first. It is read-only and boots no agent tree — it mounts the [session registry](../../packages/session-registry/session-registry/README.md) alone, so listing is fast and cannot start model work as a side effect. Every surface publishes its sessions into that registry through [`dsh-session-registry-live`](../../packages/session-registry/session-registry-live/README.md), and records whose process is gone are pruned on read, so a crashed session disappears without cleanup. `--json` emits the same records as a machine-readable array; an empty listing prints one line and exits 0. There is no workspace filter: the listing is always every live session, whatever directory it runs in. Only top-level surfaces appear — subagents share or spawn other processes and are deliberately invisible.
 
 The Web and headless surfaces boot one shared composition (`cordis.yml`): both treat the invoking directory as the default project and Workspace root, create named Workspaces beneath that root unless `--workspace-root <path>` overrides it, load applicable `AGENTS.md`/`CLAUDE.md` instructions into each agent-loop request prefix with a 65,536-byte render budget, and opt into first-message model titles. 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`).

-`dsh` 命令行入口遵循 `apps/` 组装层：`apps/*` 是位于 `packages/*` 库之上的产品组装。直接运行 `dsh` 会启动交互式 TUI 编码 agent（智能体），`dsh -p "task"` 运行一个无头轮次，`dsh meta` 以本 harness checkout 为 workspace 启动同一个 TUI，`dsh migrate` 和 `dsh upgrade` 启动一个全新的引导式 TUI 会话并在首轮调用内置 skill，`dsh list-sessions` 列出此刻正在运行的会话，`dsh web` 则提供浏览器 UI。

 TUI 界面：
 
@@ -18,7 +17,6 @@ TUI 界面：
 
 `dsh migrate` 与 `dsh upgrade` 是默认 TUI 界面之上的引导式全新会话入口：各自在调用目录中创建一个全新会话，并以一个内置 skill 播种其首轮（`dsh-migrate` 用于从其他编码 agent 迁移——opencode、pi、Claude Code、Codex；`dsh-upgrade` 用于升级本 checkout），效果等同于用户手动键入 `/skill:<name>`。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 <id>` 恢复该会话时是普通 TUI 会话，不会重复注入。
 
-`dsh list-sessions` 列出此刻正在运行的会话：会话 id、pid、运行时长、工作区和标题，最新的在前。它是只读的，不启动任何 agent 树——它只挂载[会话注册表](../../packages/session-registry/session-registry/README.md)，因此列表既快，也不会作为副作用启动模型工作。每个界面都通过 [`dsh-session-registry-live`](../../packages/session-registry/session-registry-live/README.md) 把自己的会话发布到该注册表，进程已不存在的记录会在读取时被剪除，因此崩溃的会话无需清理便会消失。`--json` 以机器可读的数组形式输出同样的记录；空列表打印一行并以 0 退出。没有工作区过滤：列表始终是全部存活会话，无论它们运行在哪个目录下。只有顶层界面会出现——subagent 共用别的进程，或 spawn 出别的进程，因此被刻意排除在列表之外。
 
 Web 和无头界面启动同一个共享组合（`cordis.yml`）：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 <path>` 覆盖，否则会在该根目录下创建具名 Workspace；它们会把适用的 `AGENTS.md`/`CLAUDE.md` 指令加载到每个 agent-loop 请求前缀中，渲染预算为 65,536 字节，并选用首条消息模型标题。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`）。

-## Problem
-
-An agent running inside tmux has no way to tell the model where it is: which session, window, and pane the process occupies, and how the window is laid out. A user directing several panes wants the model to orient itself to its own location so instructions like "the pane below" or "this window" resolve. The location must reach the model as durable, reconstructable context, not a system-prompt value rewritten in place, and must cost nothing when the location has not changed.
-
-tmux exposes this without a daemon: `$TMUX_PANE` names the process's pane, and `tmux display-message -t "$TMUX_PANE" -p '<format>'` prints any pane/window/session field. The open question was how to observe it — pull on each preparation, or push from a tmux hook — and how to avoid a per-step token cost and hidden process-local state.
-
-## Decision
-
-`@deepseek-ai/dsh-tmux-context` is an opt-in function plugin in `packages/context/tmux-context/`, alongside the other bounded request-context enrichments that define neither a tool nor a service. Shipped examples do not mount it because tmux-location disclosure and its token cost are deployment policy.
-
-**Pull on the first step of each turn, not a tmux push.** The plugin prepends an `agent/step` listener and acts only when `step === 1`. A pull model needs no background process, no hook installation in the user's tmux, and no teardown; it re-reads current state each turn so a moved, renamed, or re-laid-out pane is picked up naturally. Gating on the first step makes the reading per-turn: a location is stable within a turn, and re-querying every step would add cost without new information. A pane moved mid-turn is reflected on the next turn, which is the accepted tradeoff for the simpler design.
-
-**Read through the `ctx.bash` seam, never raw `child_process`.** The listener runs the tmux/`ps` read commands through `ctx.bash`, so the deployment's sandbox and policy apply and the plugin owns no subprocess code. Absent `ctx.bash`, absent tmux env, a wrong field count, or an empty pane id each make the attempt a no-op, matching how `workspace-context` no-ops without an `fs` provider.
-
-**Detect a real pane by tty, not by `$TMUX_PANE` alone.** `$TMUX_PANE` is inherited: a terminal launched from a tmux shell (a VS Code integrated terminal, a desktop launcher) carries `$TMUX`/`$TMUX_PANE` from that ancestor even though the process does not live in that pane, which otherwise injects a stale, wrong location. The command resolves this process's controlling terminal with `ps -o tty= -p <pid>` (the agent's own pid, passed in-process) and compares it to the pane's `#{pane_tty}`; fields are emitted only on a match. A genuine pane owns this process's tty; an inherited environment names some other pane's tty and reads as "not in tmux". Checking `$TMUX` instead does not help — it is inherited identically. This is the definitive discriminator and needs no allowlist of terminal emulators.
-
-**Own location and layout only.** The queried fields are session name, window index/name, pane index/id, window/pane active flags, and `window_layout`. Pane and window pixel sizes are excluded (layout tree conveys structure; sizes are noisy and change on every terminal resize). Sibling-pane contents are never captured (`capture-pane`), keeping the reading small and avoiding scraping unrelated, possibly sensitive, output.
-
-**Inject only on change, with optional interval floor.** When due, the plugin calls `agent.inject()` for one `user/message` with source `{ kind: 'plugin', plugin: 'tmux-context' }`. Change suppression compares the rendered state block (everything after the turn preamble line) against the latest injection of this source, found by scanning raw durable session events — so the schedule survives compaction and process resume without a process-local cache. The optional `refreshIntervalMs` (manually validated as a non-negative safe integer at plugin load) additionally suppresses injections within that window of the latest one.
-
-### Text
-
-```text
-tmux location (turn <turn>):
-session <session>, window <index> "<name>", pane <index> <pane-id>
-window active=<0|1>, pane active=<0|1>, layout <window-layout>
-```
-
-The turn preamble is the volatile first line; the two-line state block below it is the unit compared for change suppression, so re-injection is driven by tmux state, not loop position.
-
-### Durability and request reconstruction
-
-Each reading is a normal surface node until compaction shadows it; the plugin contributes nothing to system-prompt assembly and `request/header` carries no tmux-context text. The reading records a preparation attempt, not a committed step: because the prepended listener runs first, its append may remain when a later `agent/step` listener cancels or fails the attempt, and the append-only log performs no rollback.
-
-The published `./invariant` companion registers no runtime check: a reading is a per-turn snapshot of external tmux state, so the session holds no cross-event relation to validate, and scheduling and format stay pinned by the package's pipeline tests.
-
-## Consequences
-
-An agent booted inside tmux now receives its own session/window/pane location and window layout as durable, source-attributed context, updated per turn when the location changes. Deployments opt in through cordis.yml; the default spine and shipped examples stay silent. Outside a real tmux pane — including a terminal that merely inherited `$TMUX`/`$TMUX_PANE` — or without a `ctx.bash` executor, the plugin is inert with no error, so composing it is safe everywhere. Because the reading is one durable `user/message`, it survives compaction as ordinary history, contributes nothing to system-prompt assembly or request headers, and costs at most one two-line message per changed turn. The pull model adds one bash execution (through the sandboxed bash seam) on the first step of each turn that is due — internally a `ps` tty probe, a `tmux display-message` tty query, and the field query. Only the optional interval floor suppresses the query itself; an unchanged location is known only after querying, so it suppresses the injection alone.
-
-## Testing
-
-Unit tests pin: first-step injection and source/surface metadata; the `$TMUX_PANE`-keyed command including its `#{pane_tty}`-vs-`ps -o tty=` guard; step-gating; change suppression across turns and re-injection on a moved pane; positive-interval suppression and threshold; every no-op path (no bash, nonzero exit, wrong field count, empty pane id, aborted signal); prepended ordering before ordinary `agent/step` listeners; resilience to a corrupt prior reading (non-text block, single-line text); and config rejection of negative and non-integer intervals. Per-file coverage is 100%.
-
-## Alternatives considered
-
-- **Push from a tmux hook / background watcher** — rejected: requires installing hooks in the user's tmux and a background process with teardown, to gain mid-step freshness that per-turn context does not need.
-- **Run every step** — rejected: location is stable within a turn; re-querying adds token cost without new information. Gating on `step === 1` yields per-turn readings.
-- **Raw `child_process`** — rejected: bypasses the sandbox/policy seam and hand-rolls subprocess code the `ctx.bash` executor already owns.
-- **Include pane/window pixel sizes** — rejected: sizes churn on every resize and add noise; the layout tree already conveys structure.
-- **Scrape sibling panes with `capture-pane`** — rejected: large, noisy, and privacy-sensitive; out of scope for "own location".
-- **Dynamic system-prompt section** — rejected: replacing a value erases the earlier readings behind prior reasoning and is not reconstructable; one durable attributed message records each location where it became visible.
-- **Trust `$TMUX_PANE` (or `$TMUX`) presence** — rejected: both are inherited by terminals launched from a tmux shell (VS Code integrated terminal), so a non-pane process injects a stale location. The pane `#{pane_tty}` vs. this process's controlling tty is the definitive check.
-- **Denylist known terminal emulators (e.g. `TERM_PROGRAM=vscode`)** — rejected: a partial, ever-growing list that still misses other launchers; the tty match is exact and launcher-agnostic.
-- **A runtime invariant validating each reading's turn, position, and format** — shipped initially, then removed: it re-derived the producer's own scheduling from the log and asserted a regex over text the same package had just rendered, so it restated `apply()` rather than checking an independent relation. Every failure it could report required an edit to this package, which its pipeline tests already catch. Reintroduce a companion check only for a relation the plugin does not itself compute — for example if readings gain cross-turn ordering or enclosure obligations that another package can violate.

-# Agent Note：tmux 位置上下文

-Status: implemented

-## 问题
-
-运行在 tmux 内的 agent 无法告诉模型自己身在何处：进程占据哪个 session、window、pane，以及 window 如何布局。当用户操作多个 pane 时，希望模型能对自身位置有所定位，从而让"下方的 pane""这个 window"之类的指令得以解析。位置必须以持久、可重建的上下文形式送达模型，而非在原地被改写的系统提示值，并且当位置未变化时不产生任何成本。
-
-tmux 无需守护进程即可暴露这些信息：`$TMUX_PANE` 标识进程所在 pane，`tmux display-message -t "$TMUX_PANE" -p '<format>'` 可打印任意 pane/window/session 字段。待决问题在于如何观测——在每次准备时拉取，还是由 tmux hook 推送——以及如何避免逐步骤 token 成本与隐藏的进程内状态。
-
-## 决策
-
-`@deepseek-ai/dsh-tmux-context` 是位于 `packages/context/tmux-context/` 的可选启用型函数插件，与其他既不定义工具也不定义服务的有界请求上下文增强并列。随附示例不挂载它，因为 tmux 位置披露及其 token 成本属于部署策略。

-**在每轮的第一个 step 拉取，而非 tmux 推送。** 插件前置注册一个 `agent/step` 监听器，仅在 `step === 1` 时动作。拉取模型无需后台进程、无需在用户的 tmux 中安装 hook、也无需清理；它每轮重新读取当前状态，因此被移动、改名或重新布局的 pane 都会被自然感知。以第一个 step 为门槛使读数按轮次生成：位置在一轮内是稳定的，逐步骤重复查询只会增加成本而不带来新信息。轮次中途移动的 pane 会在下一轮反映，这是换取更简单设计所接受的取舍。
-
-**通过 `ctx.bash` seam 读取，绝不用裸 `child_process`。** 监听器通过 `ctx.bash` 运行 tmux／`ps` 只读命令，从而应用部署方的沙箱与策略，插件不拥有任何子进程代码。`ctx.bash` 缺失、tmux 环境缺失、字段数不符或 pane id 为空，都会使本次尝试成为空操作，与 `workspace-context` 在无 `fs` provider 时的空操作一致。
-
-**以 tty 判定真实 pane，而非仅凭 `$TMUX_PANE`。** `$TMUX_PANE` 会被继承：从 tmux shell 启动的终端（VS Code 集成终端、桌面启动器）会从该祖先进程带上 `$TMUX`／`$TMUX_PANE`，即使进程并不位于那个 pane 中，否则就会注入一个陈旧且错误的位置。命令用 `ps -o tty= -p <pid>`（在进程内传入 agent 自身的 pid）解析本进程的控制终端，并与 pane 的 `#{pane_tty}` 比较；只有匹配时才输出字段。真正的 pane 拥有本进程的 tty；继承而来的环境指向的是另一个 pane 的 tty，因而被读作"不在 tmux 中"。改为检查 `$TMUX` 也无济于事——它同样会被继承。这是决定性的判别依据，且无需维护终端模拟器名单。
-
-**仅自身位置与布局。** 查询字段为 session name、window index/name、pane index/id、window/pane 活动标志以及 `window_layout`。省略 pane 与 window 像素尺寸（布局树已传达结构；尺寸嘈杂且每次终端缩放都会变化）。从不采集相邻 pane 内容（`capture-pane`），使读数保持小巧，并避免抓取无关、可能敏感的输出。
-
-**仅在变化时注入，并可选间隔下限。** 需要时，插件调用 `agent.inject()` 注入一条来源为 `{ kind: 'plugin', plugin: 'tmux-context' }` 的 `user/message`。变化抑制将渲染出的状态块（轮次前缀行之后的全部内容）与该来源的最近一次注入比较，后者通过扫描原始持久会话事件获得——因此调度可跨压缩与进程恢复存续，无需进程内缓存。可选的 `refreshIntervalMs`（在插件加载时手动校验为非负安全整数）会额外抑制距最近一次注入不足该窗口的注入。
-
-### 文本
-
-```text
-tmux location (turn <turn>):
-session <session>, window <index> "<name>", pane <index> <pane-id>
-window active=<0|1>, pane active=<0|1>, layout <window-layout>
-```
-
-轮次前缀是易变的首行；其下的两行状态块才是变化抑制所比较的单元，因此重新注入由 tmux 状态驱动，而非循环位置。
-
-### 持久性与请求重建
-
-每条读数在被压缩遮蔽前都是普通表层节点；插件对系统提示装配毫无贡献，`request/header` 也不携带任何 tmux-context 文本。读数记录的是一次准备尝试，而非已提交的 step：由于前置监听器最先运行，当后续 `agent/step` 监听器取消或失败时其追加可能仍会保留，只追加的日志不做回滚。
-
-发布的 `./invariant` 伴生插件不注册任何运行时检查：读数是外部 tmux 状态的按轮快照，会话中不存在需要校验的跨事件关系，调度与格式由本包的管线测试固定。
-
-## 后果
-
-启动于 tmux 内的 agent 现在会以持久、带来源标记的上下文收到自身的 session/window/pane 位置及 window 布局，并在位置变化时按轮次更新。部署方通过 cordis.yml 选择启用；默认 spine 与随附示例保持沉默。在真实 tmux pane 之外——包括仅继承了 `$TMUX`／`$TMUX_PANE` 的终端——或没有 `ctx.bash` 执行器时，插件保持惰性且不报错，因此在任何地方组合它都安全。由于读数是一条持久的 `user/message`，它作为普通历史经受压缩，对系统提示装配与请求头毫无贡献，且每个发生变化的轮次至多花费一条两行消息。拉取模型在每个到期轮次的第一个 step 增加一次 bash 执行（经沙箱化的 bash seam）——内部包含一次 `ps` tty 探测、一次 `tmux display-message` tty 查询和字段查询。只有可选的间隔下限会抑制查询本身；位置是否变化只有在查询之后才知道，因此它只抑制注入。
-
-## 测试
-
-单元测试固定了：首个 step 的注入及来源/表层元数据；以 `$TMUX_PANE` 为键的命令（含其 `#{pane_tty}` 与 `ps -o tty=` 的比对守卫）；step 门槛；跨轮次的变化抑制与 pane 移动时的重新注入；正间隔抑制与阈值；每条空操作路径（无 bash、非零退出、字段数不符、pane id 为空、信号已取消）；前置排序先于普通 `agent/step` 监听器；对损坏的历史读数（非文本块、单行文本）的容错；以及配置对负值与非整数间隔的拒绝。逐文件覆盖率为 100%。
-
-## 考虑过的替代方案
-
-- **由 tmux hook / 后台监视器推送**——否决：需要在用户的 tmux 中安装 hook，并引入带清理的后台进程，只为换取按轮次上下文并不需要的步内新鲜度。
-- **每个 step 都运行**——否决：位置在一轮内稳定；重复查询只增加 token 成本而无新信息。以 `step === 1` 为门槛得到按轮次读数。
-- **裸 `child_process`**——否决：绕过沙箱/策略 seam，并手写 `ctx.bash` 执行器已拥有的子进程代码。
-- **包含 pane/window 像素尺寸**——否决：尺寸每次缩放都变动、徒增噪声；布局树已传达结构。
-- **用 `capture-pane` 抓取相邻 pane**——否决：庞大、嘈杂且涉及隐私；超出"自身位置"范围。
-- **动态系统提示区块**——否决：替换某个值会抹去支撑先前推理的历史读数且不可重建；单条持久且带来源的消息在每个位置变得可见时予以记录。
-- **信任 `$TMUX_PANE`（或 `$TMUX`）存在即可**——否决：两者都会被从 tmux shell 启动的终端（VS Code 集成终端）继承，于是非 pane 进程会注入陈旧位置。pane 的 `#{pane_tty}` 与本进程控制终端的比对才是决定性检查。
-- **对已知终端模拟器设黑名单（如 `TERM_PROGRAM=vscode`）**——否决：名单不完整且会不断增长，仍会漏掉其他启动器；tty 比对精确且与启动器无关。
-- **用运行时 invariant 校验每条读数的轮次、位置与格式**——最初随包发布，随后移除：它从日志中重新推导生产者自身的调度，并对同一个包刚刚渲染出的文本断言正则，因此只是重述 `apply()`，而非检查一条独立关系。它能报出的每种失败都必须先修改本包，而这些本包的管线测试已经覆盖。仅当出现插件自身并不计算的关系时才重新引入伴生检查——例如读数将来具备可被其他包破坏的跨轮次顺序或包裹义务。

-# Agent Note: source-guard denies direct staging-checkout edits
-
-Status: implemented
-
-English | [中文](2026-07-28-source-guard-staging-edit-gate.zh.md)
-
-## Problem
-
-The [`dsh-customize`](../../../../skills/dsh-customize/SKILL.md) skill governs every personal change to a dsh source checkout: implement in a task worktree branched from the staging tip, then integrate under `.agents/merge.lock`. Its central rule is negative — do not edit the personal staging checkout directly — and a negative rule delivered only as prompt text fails in exactly the case that matters. An agent that never loads the skill never sees the rule, and one that loads it early can still forget it thirty tool calls later. The failure is silent and expensive: commits land on the staging branch that the launcher runs from, outside any task branch, with no lock held and no rollback worktree.
-
-Prompt guidance cannot fix this, because the guidance is what went unread. The rule needs an enforcement point.
-
-## Decision
-
-`@deepseek-ai/dsh-source-guard` (`packages/guard/source-guard/`) is a `tools/pre-execute` listener that returns `{kind: 'deny', reason}` for a `write` or `edit` whose target resolves inside a protected staging worktree, unless the calling session's durable log already records a successful `skill` call naming `dsh-customize`. It registers no service and contributes no prompt text or tool schema; an allowed call is indistinguishable from one made without the plugin. It is not in any shipped default composition.
-
-### Git identity from files, not a path prefix and not `git`
-
-Whether a path is protected is decided by reading `.git`, its `gitdir:` pointer, and `HEAD`. Three shapes resolve: a plain clone (`.git` is a directory that is its own common dir), a linked worktree (`.git` is a file pointing at `<common>/worktrees/<name>`, whose common dir is two levels up), and a detached HEAD (`HEAD` holds a raw object id and names no branch). A `gitdir:` pointer resolves whether absolute — what `git worktree add` writes — or relative, which git resolves against the worktree directory holding it.
-
-Denial requires the target's worktree to match the launcher's on both identities: the same shared git directory and the same branch. Both come from resolving `protectedCheckout`, so nothing about the protected branch is configured. An earlier revision matched a `dsh-staging/*` name pattern instead; the exact-branch rule replaced it because a pattern is wrong in both directions. It denied every sibling staging worktree an old install had left behind, none of which runs a launcher, and it silently protected nothing for a maintainer whose staging branch follows no naming convention — a fatal property for a shipped default that must hold for checkouts [`scripts/install.sh`](../../../../scripts/install.sh) did not create.
-
-A path-prefix rule would have been wrong, not merely imprecise. The task worktrees the skill prescribes live *inside* the protected tree at `<staging>/.worktrees/...`, so a prefix rule would deny every edit the workflow requires. Resolution walks outward from the target and stops at the first enclosing worktree, so it reports the innermost one: a nested task worktree answers with its own task branch and is allowed, while the launcher's own tree answers with the launcher's branch and is denied.
-
-Two path details decide whether the gate holds at all, and both are enforcement, not polish. Repository identity is compared on symlink-resolved paths (`canonicalPath` from `dsh-sandbox`), because a session cwd under `/var/...` and a configured path under `/private/var/...` are the same macOS directory and a lexical comparison would fail open on every write. And a relative `file_path` is resolved against the calling session's workspace, exactly as `dsh-tool-fs` resolves it; judging only absolute paths would have left a relative path as an unguarded route to a protected file.
-
-`protectedCheckout` names a path inside the guarded checkout, defaulting to this module's own file. That resolves the checkout the running harness was launched from — the live deployment, whatever its branch is named. A harness running from an installed copy resolves a different repository, or none, and guards nothing; the rule is meaningless outside a source checkout.
-
-The shipped TUI composition loads the plugin with these defaults, so every source install is protected without configuration. It is inert for an ordinary project: a workspace in another repository, or none, never matches the launcher's identities.
-
-### Satisfaction replayed from the durable log
-
-The gate lifts on a `tool/call` naming the `skill` tool whose arguments parse to `{name: <requiredSkill>}`, paired by call id with a non-error `tool/result`. Both fields are already durable (`packages/core/session/src/types.ts`), so this needs no new session event and no coupling to skill-provider internals.
-
-The log is the only state. In-memory satisfaction (the `WeakMap` shape [`repeat-tool-guard`](../../archived/feature/2026-07-08-repeat-tool-guard.md) uses for its chains) would be smaller, but it loses satisfaction on resume: a resumed session that already read the skill would be told to read it again, and the denial would look like a bug rather than a rule. Replay costs a scan bounded by the first hit and buys resume correctness.
-
-### Fail open, deliberately
-
-A path outside any worktree, a detached HEAD, a foreign repository, a malformed `gitdir:` pointer, and unreadable metadata all leave the call to the rest of the chain. The alternative — denying whenever git identity is unavailable — converts any `.git` permission problem into a harness that cannot write files at all. The guard exists to prevent one specific, recoverable mistake; it must not become a larger outage than the mistake.
-
-### Narrow scope
-
-`read` is never gated: inspecting staging violates nothing, and the skill explicitly permits read-only questions. `bash` is not gated either. Reliably classifying mutating shell commands is a matcher problem with no honest completion condition, so a determined model can still change staging through a shell. This is a boundary against forgetting, not a sandbox against intent.
-
-## Alternatives considered
-
-- **Advisory reminder instead of denial** (`additionalContexts` on `tools/post-execute`, the `repeat-tool-guard` shape). Rejected: the write has already happened when the reminder arrives, so the violation is committed and the guidance is again just text.
-- **`{kind: 'ask'}` routed to approval.** Rejected: it prompts on every legitimate task-worktree edit in the common case, and degrades to denial in a composition without approval support, making behavior depend on unrelated plugins.
-- **Running `git rev-parse` through `ctx.subprocess`.** Rejected after measuring the alternative: two file reads answer the same question with no process spawn per gated write, no `git` on `PATH` requirement, and no subprocess dependency. Reading `.git` and `HEAD` is a stable on-disk format, not an implementation detail.
-- **Explicit `protectedRoots` config with no detection.** Rejected: it makes the common case require configuration to be correct, and a stale absolute path silently disables protection.
-- **A configurable staging-branch name pattern** (`stagingBranchPatterns`, default `dsh-staging/*`). Shipped first, then removed: it protects the wrong set in both directions — every stale sibling worktree that runs no launcher, and nothing at all for a maintainer whose branch is named otherwise. Deriving the branch from the launcher needs no configuration and cannot be misconfigured.
-- **Auto-detecting the checkout with no override.** Rejected: the detection is a default, not a law; a deployment guarding a different checkout, or running from an installed copy, needs the explicit value.
-- **Denying everything under the checkout root, `.worktrees/` included.** Rejected: it blocks the workflow the skill prescribes, so the guard would fire on every legitimate task edit.
-- **Gating `bash` with a mutating-command matcher.** Deferred, not rejected: worth revisiting if bypasses are observed in practice. A matcher that is wrong in either direction is worse than an honestly narrow gate.
-
-## Consequences
-
-The rule now holds without depending on the model having read it, and the denial names the path, the branch, and the skill, so the model's next action is determined rather than guessed. Enforcement sits at the operation boundary that owns the decision, so it cannot be bypassed by prompt filtering or listener order.
-
-Shipping it in the TUI default means every source install is protected without configuration, and the protection follows the launcher across upgrades because the branch is derived rather than named. The cost of that reach is that the plugin loads for every user, including those whose workspace it can never match.
-
-What it cost otherwise: the guard is only as complete as its tool list, and `bash` remains open. Worktree identity is cached per directory for the plugin's lifetime, so a mid-session branch switch is not observed on either side. Only the launcher's own checkout is protected, so a stale sibling stays editable. Loading the skill lifts the gate for the whole session without verifying the workflow was actually followed — the gate proves the instructions were read, not obeyed. Satisfaction is per session, so a subagent with its own session must load the skill itself.
-
-## Testing
-
-Unit suites drive a real agent loop against a mock adapter over real git-metadata fixtures — a staging worktree, a task worktree nested inside it, a plain clone, a foreign repository on a staging-named branch, a detached HEAD, absolute and relative `gitdir:` pointers, a symlinked route to one repository, a malformed pointer, and unreadable metadata — covering both source files to per-file 100%. A companion `invariant.ts` validates the durable denial's shape, since the refusal text is the package's only model-visible output and is actionable only when it names the path, branch, and skill.
-
-The real-composition smoke boots `examples/headless-agent/tests/fixtures/guard/source-guard/cordis.yml` through the Loader and the headless app, and asserts three things about the assembled run: the tool result is an error, its text is the exact denial, and the targeted file still holds its original bytes — enforcement before dispatch, not advice after it.
-
-An ACP snapshot scenario (`source-guard-staging-deny`) originally owned the assembled transcript, seeding a staging worktree in the harness's generated cwd through a new `Scenario.prepareCwd` hook — git never tracks an entry named `.git` and `.gitignore` excludes every `worktrees/` directory, so the fixture committed the two `HEAD` bodies and the hook assembled the real layout. Authoring it paid for itself immediately: it exposed both path defects above (the transcript showed `fs-policy` answering first wherever the guard had quietly declined to judge) and then caught its own first fixture, whose ignored `worktrees/` path passed locally from an untracked file. The scenario was later removed with the assembled-run evidence consolidated into the Loader-composition smoke; the `prepareCwd` hook it introduced remains part of the snapshot harness for repository-shaped fixtures.

-# Agent Note: source-guard 拒绝直接编辑 staging 检出目录
-
-Status: implemented
-
-[English](2026-07-28-source-guard-staging-edit-gate.md) | 中文
-
-## Problem
-
-[`dsh-customize`](../../../../skills/dsh-customize/SKILL.md) skill（技能）规范对 dsh 源码检出的每项个人变更：先在从 staging 分支顶端分出的任务 worktree 中实现，再于 `.agents/merge.lock` 保护下完成集成。它的核心规则是一条禁令：不得直接编辑个人 staging 检出目录；而若只通过提示词文本传达禁令，它恰好会在最要紧的场景中失效。从未加载该 skill 的 agent（智能体）根本看不到规则；即便尽早加载，也仍可能在三十次工具调用后将其忘掉。这种失败既静默又代价高昂：提交会落在启动器实际运行的 staging 分支上，不属于任何任务分支，既未持有锁，也没有用于回滚的 worktree。
-
-提示词指导无法解决这个问题，因为未被阅读的正是这些指导。该规则需要一个强制执行点。
-
-## Decision
-
-`@deepseek-ai/dsh-source-guard`（`packages/guard/source-guard/`）是一个 `tools/pre-execute` 监听器；它会返回 `{kind: 'deny', reason}`，拒绝目标解析到受保护 staging worktree 内的 `write` 或 `edit`，除非调用会话的持久日志已经记录过一次成功的 `skill` 调用，且名称为 `dsh-customize`。它不注册服务，也不贡献提示词文本或工具 schema；获准的调用与未加载该插件时的调用没有区别。任何已交付的默认组合都不包含它。
-
-### 从文件而非路径前缀或 `git` 判定 Git 身份
-
-系统通过读取 `.git`、其中的 `gitdir:` 指针以及 `HEAD` 来判断路径是否受保护。它可以解析三种形态：普通克隆（`.git` 是目录，且自身就是共享目录）、链接 worktree（`.git` 是文件，指向 `<common>/worktrees/<name>`，其共享目录位于上两级）以及 HEAD 分离状态（`HEAD` 保存原始对象 id，不指向任何分支）。`gitdir:` 指针无论是绝对路径（`git worktree add` 写入的形式）还是相对路径都可以解析；Git 会以包含该指针的 worktree 目录为基准解析相对路径。
-
-只有目标的 worktree 在两项身份上都与启动器的 worktree 匹配时才会拒绝：共用同一个共享 Git 目录，且分支相同。这两项身份均通过解析 `protectedCheckout` 得出，因此无需配置受保护分支的任何信息。较早版本则匹配 `dsh-staging/*` 名称模式；现已改用确切分支规则，因为模式会在两个方向上出错。它会拒绝旧安装留下的每一个同级 staging worktree，尽管其中没有任何一个运行着启动器；对于 staging 分支不遵循任何命名约定的维护者，它又会静默地完全不提供保护——而已交付的默认配置必须在 [`scripts/install.sh`](../../../../scripts/install.sh) 未创建的检出目录上也能生效，这一属性是致命的。
-
-路径前缀规则不仅不精确，而且本身就是错误的。该 skill 规定的任务 worktree 位于受保护树*内部*的 `<staging>/.worktrees/...`，因此前缀规则会拒绝工作流要求的每一次编辑。解析过程从目标向外逐层查找，遇到第一个所属 worktree 时停止，因此返回最内层的 worktree：嵌套的任务 worktree 会返回自身的任务分支并获准，而启动器自身所在的树会返回启动器的分支并被拒绝。
-
-有两个路径细节决定门禁究竟能否生效，二者都是强制执行要求，而非细节润色。仓库身份会按解析符号链接后的路径进行比较（使用 `dsh-sandbox` 的 `canonicalPath`），因为位于 `/var/...` 下的会话 cwd 和位于 `/private/var/...` 下的配置路径在 macOS 上是同一个目录，若按路径字符串比较，每次写入都会故障放行（fail-open）。此外，相对 `file_path` 会完全按照 `dsh-tool-fs` 的方式，相对于调用会话的工作区解析；若只判断绝对路径，相对路径就会成为绕过门禁访问受保护文件的路径。
-
-`protectedCheckout` 指定受保护检出目录内的一条路径，默认值为本模块自身的文件。由此解析出运行中 harness 的启动来源检出目录——当前运行的部署，无论其分支采用什么名称。若 harness 从已安装副本运行，解析出的会是另一个仓库或没有仓库，因此不会保护任何内容；该规则在源码检出之外没有意义。
-
-已交付的 TUI 组合会以这些默认值加载插件，因此每个源码安装无需配置即可受到保护。对于普通项目，它不会生效：若工作区位于其他仓库中，或不存在工作区，就绝不会匹配启动器的身份。
-
-### 从持久日志回放满足状态
-
-如果日志中存在一条 `tool/call`，它调用名为 `skill` 的工具，参数可解析为 `{name: <requiredSkill>}`，且按调用 id 能配对到非错误的 `tool/result`，门禁即解除。二者都已持久化（`packages/core/session/src/types.ts`），因此无需新增会话事件，也不与 skill 提供方内部实现耦合。
-
-日志是唯一状态。在内存中记录满足状态（`WeakMap` 结构，[`repeat-tool-guard`](../../archived/feature/2026-07-08-repeat-tool-guard.md) 将其用于调用链）所需实现会更小，但恢复后满足状态会丢失：一个已经读取过该 skill 的恢复会话会被要求再次读取，而这次拒绝看起来会像缺陷而不是规则。回放的代价是扫描日志，但首次命中即停止，并换来恢复行为正确。
-
-### 刻意采用故障放行
-
-目标路径不在任何 worktree 内、HEAD 分离、属于其他仓库、`gitdir:` 指针格式错误或元数据不可读时，调用都会交给调用链的其余部分处理。反过来，只要无法判定 Git 身份就拒绝，会让任何 `.git` 权限问题都导致 harness 完全无法写文件。该 guard 旨在防止一种特定且可恢复的错误，不得造成比该错误更严重的故障。
-
-### 范围收窄
-
-`read` 从不受门禁限制：检查 staging 不会违反任何规则，而且该 skill 明确允许只读提问。`bash` 同样不受门禁限制。要可靠判定哪些 shell 命令会修改状态，需要构造一个无法给出可信完备标准的匹配器，因此执意修改的模型仍可通过 shell 修改 staging。这是一道防止遗忘的边界，不是阻止刻意操作的沙箱。
-
-## Alternatives considered
-
-- **用建议性提醒代替拒绝**（使用 `additionalContexts`，挂载在 `tools/post-execute` 上，采用 `repeat-tool-guard` 的形态）。不予采纳：提醒到达时写入已经发生，违规已成事实，而指导又一次沦为纯文本。
-- **将 `{kind: 'ask'}` 交给审批。** 不予采纳：在常见场景中，它会对任务 worktree 内每次合法编辑都发起询问；在没有审批支持的组合中还会退化为拒绝，使行为取决于无关插件。
-- **运行 `git rev-parse`，并通过 `ctx.subprocess` 执行。** 对替代方案进行实测后不予采纳：读取两个文件即可回答同一问题，每次受门禁限制的写入都无需 spawn 进程，不要求 `git` 存在于 `PATH` 中，也不依赖子进程。读取 `.git` 与 `HEAD` 所依据的是稳定的磁盘格式，而非实现细节。
-- **显式配置 `protectedRoots`，不做检测。** 不予采纳：这会让常见场景的保护效果依赖配置正确性，而陈旧的绝对路径会静默禁用保护。
-- **可配置的 staging 分支名称模式**（`stagingBranchPatterns`，默认 `dsh-staging/*`）。最初随产品交付，随后删除：它从两个方向划错了保护范围——既纳入每个不运行启动器的陈旧同级 worktree，又完全不保护分支另有名称的维护者。由启动器派生分支无需配置，也不可能配置错误。
-- **自动检测检出目录，不提供覆盖项。** 不予采纳：检测只是默认行为，而非不可更改的规定；若部署要保护另一个检出目录，或自身从已安装副本运行，就需要显式值。
-- **拒绝检出根目录下的一切操作，包括 `.worktrees/`。** 不予采纳：这会阻断该 skill 规定的工作流，让 guard 在每次合法任务编辑时触发。
-- **用修改类命令匹配器把守 `bash`。** 推迟而非否决：如果实际观察到绕过行为，值得重新考虑。任一方向判断错误的匹配器，都不如如实限定范围的门禁。
-
-## Consequences
-
-如今，该规则无需依赖模型已经读过它也能生效；拒绝理由会列出路径、分支与 skill，让模型的下一步操作明确，无需猜测。强制执行位于拥有该决策的操作边界，因此提示词过滤或监听器顺序都无法绕过它。
-
-将其纳入 TUI 默认组合意味着每个源码安装无需配置即可受到保护；由于分支是派生而非按名称指定，保护会在升级时跟随启动器。这种覆盖范围的代价是插件会为每位用户加载，包括工作区永远不可能匹配启动器身份的用户。
-
-除此之外的代价是：guard 的完整程度受限于其工具列表，`bash` 仍保持开放。worktree 身份在插件生命周期内按目录缓存，因此无法观察到任一侧在会话中途切换分支。只保护启动器自身的检出目录，因此陈旧的同级检出目录仍可编辑。加载该 skill 会为整个会话解除门禁，却不会验证工作流是否确实得到遵循——门禁只能证明指令已被阅读，不能证明已被执行。满足状态按会话隔离，因此拥有独立会话的 subagent 必须自行加载该 skill。

-单元测试套件基于真实 Git 元数据 fixture（测试前置数据），使用 mock 适配器驱动真实 agent loop（智能体循环）：覆盖一个 staging worktree、嵌套其中的任务 worktree、普通克隆、位于 staging 命名分支上的其他仓库、HEAD 分离状态、绝对和相对 `gitdir:` 指针、指向同一仓库的符号链接路径、格式错误的指针以及不可读元数据，使两个源码文件都达到逐文件 100% 覆盖率。配套的 `invariant.ts` 会验证持久拒绝的结构，因为拒绝文本是该包唯一面向模型的输出，且只有其中列出路径、分支和 skill 时才具有可操作性。
-
-真实组合冒烟测试通过 Loader 与 headless 应用启动 `examples/headless-agent/tests/fixtures/guard/source-guard/cordis.yml`，并对组装后的运行断言三项事实：工具结果是错误、文本与拒绝理由逐字一致、目标文件仍保留原始字节。这证明系统在分发前强制执行规则，而不是事后给出建议。
-
-一个 ACP（Agent Client Protocol）快照场景（`source-guard-staging-deny`）最初负责组装后的 transcript（文本记录），通过新的 `Scenario.prepareCwd` 钩子在 harness 生成的 cwd 中植入 staging worktree——Git 永远不会跟踪名为 `.git` 的条目，且 `.gitignore` 会排除所有 `worktrees/` 目录，因此 fixture 提交两个 `HEAD` 的内容，由钩子组装真实布局。编写它立刻证明了投入的价值：它暴露了上述两个路径缺陷（transcript 显示每当 guard 悄然不作判断时 `fs-policy` 都会率先响应），随后又发现了自身首版 fixture 的问题——被忽略的 `worktrees/` 路径因未跟踪文件而在本地通过。该场景后来被移除，组装运行证据合并进 Loader 组合冒烟测试；它引入的 `prepareCwd` 钩子仍留在快照 harness 中，服务于仓库形态的 fixture。

-Opt-in durable context naming the tmux session, window, and pane this agent process runs in, plus the window's pane-tree layout. Sampled once per turn during model-request preparation. `dsh-agent-spine-demo` and shipped examples do not mount it. Decision record: [the tmux-context Agent Note](../../../.agents/notes/implemented/feature/2026-07-27-tmux-location-context.md).
-
-## Config
-
-```yaml
-- id: tmux-context
-  name: '@deepseek-ai/dsh-tmux-context'
-  config:
-    refreshIntervalMs: 60000 # optional; omit or set to 0 to inject on every changed turn
-```
-
-`refreshIntervalMs` must be a non-negative safe integer. Omission or `0` injects whenever the tmux state changed since the last injection. A positive value additionally suppresses injections that fall within that many milliseconds of the latest one.
-
-## How it reads tmux
-
-The plugin prepends an `agent/step` listener that runs only on the first step of each turn. When due, it runs one read-only command through the `ctx.bash` executor seam:
-
-```sh
-[ -n "$TMUX_PANE" ] || exit 1
-self_tty=$(ps -o tty= -p <pid> | tr -d ' ')
-pane_tty=$(tmux display-message -t "$TMUX_PANE" -p '#{pane_tty}') || exit 1
-[ "$pane_tty" = "/dev/$self_tty" ] || exit 1
-exec tmux display-message -t "$TMUX_PANE" -p '<format>'
-```
-
-`$TMUX_PANE` alone is insufficient: a terminal launched from a tmux shell (a VS Code integrated terminal, a desktop launcher) **inherits** `$TMUX` and `$TMUX_PANE` from that ancestor, so the variables are present even though the process does not live in that pane. The command therefore also compares the pane's `#{pane_tty}` against this process's own controlling terminal (`ps -o tty=` for its pid): a genuine pane owns this process's tty, while an inherited environment names some other pane's tty. Running through `ctx.bash` applies the deployment's sandbox and policy; the plugin owns no subprocess code. When `ctx.bash` is absent, the process is not in a real tmux pane (`$TMUX_PANE` unset, or the tty does not match ⇒ nonzero exit), or the reading is malformed, the attempt is a no-op, never an error.
-
-State is pulled on every eligible turn — a moved, renamed, or re-laid-out pane is picked up without any tmux hook or background process. The plugin re-injects only when the rendered tmux state differs from its last injection, so an unchanged location adds nothing.
-
-## Timing semantics
-
-When an injection is due, the plugin appends one injected `user/message` through `agent.inject()` before `step/start`, with source `{ kind: 'plugin', plugin: 'tmux-context' }`. Change suppression and interval scheduling scan the raw durable session events for the latest injection of this source, so the schedule survives compaction and resumed processes without process-local cache state; sessions schedule independently. The reading records a request-preparation attempt, not a committed step; because the listener runs first, its append may remain when a later pre-step listener cancels or fails the attempt (the log is append-only and the plugin performs no rollback).
-
-## Model Experience
-
-### Preparation-time tmux location
-
-#### What the model sees
-
-On each turn whose tmux state changed, one source-tagged context message with the three lines below. `<window-layout>` is tmux's compact pane-tree description; pane and window pixel sizes are intentionally excluded, and the contents of sibling panes are never captured.
-
-##### Changed-turn reading
-
-```markdown
-tmux location (turn <turn>):
-session <session>, window <index> "<name>", pane <index> <pane-id>
-window active=<0|1>, pane active=<0|1>, layout <window-layout>
-```
-
-#### Token effect
-
-Each two-line reading accumulates until compaction shadows it. Unchanged locations and interval suppression add nothing.
-
-#### KV Cache effect
-
-Append-only; newly visible content follows the reusable request prefix and does not invalidate existing KV-cache entries.
-
-## Known Limitations and Deferred Work
-
-- **First step only** — a pane moved or resized mid-turn is reflected on the next turn, not between steps.
-- **Own location only** — the plugin never captures the visible text of sibling panes.
-- **Layout, not size** — pane/window pixel dimensions are omitted; only the layout tree and active flags are reported.
-- **Tab-delimited fields** — a tmux window name containing the literal two-character sequence `\t` would mis-split the reading and be skipped as malformed; ordinary names are unaffected.
-- **tty-based pane detection** — the process is considered "in tmux" only when its controlling terminal matches `$TMUX_PANE`'s `#{pane_tty}`. This deliberately excludes terminals that inherited `$TMUX`/`$TMUX_PANE` from a tmux ancestor (e.g. a VS Code integrated terminal). `ps -o tty=` is POSIX; the check is a no-op wherever it or `#{pane_tty}` is unavailable.

-
-## 配置
-
-```yaml
-- id: tmux-context
-  name: '@deepseek-ai/dsh-tmux-context'
-  config:
-    refreshIntervalMs: 60000 # optional; omit or set to 0 to inject on every changed turn
-```
-
-`refreshIntervalMs` 必须是非负安全整数。省略或 `0` 表示只要 tmux 状态自上次注入以来发生变化就注入。正值会额外抑制距最近一次注入不足该毫秒数的注入。
-
-## 如何读取 tmux
-
-插件前置注册一个 `agent/step` 监听器，仅在每轮的第一个 step 运行。当需要注入时，它通过 `ctx.bash` 执行器 seam 运行一条只读命令：
-
-```sh
-[ -n "$TMUX_PANE" ] || exit 1
-self_tty=$(ps -o tty= -p <pid> | tr -d ' ')
-pane_tty=$(tmux display-message -t "$TMUX_PANE" -p '#{pane_tty}') || exit 1
-[ "$pane_tty" = "/dev/$self_tty" ] || exit 1
-exec tmux display-message -t "$TMUX_PANE" -p '<format>'
-```

-仅凭 `$TMUX_PANE` 并不足够：从 tmux shell 启动的终端（VS Code 集成终端、桌面启动器）会从该祖先进程**继承** `$TMUX` 与 `$TMUX_PANE`，因此即使进程并不位于那个 pane 中，这些变量依然存在。为此该命令还会把 pane 的 `#{pane_tty}` 与本进程自己的控制终端（对其 pid 执行 `ps -o tty=`）作比较：真正的 pane 拥有本进程的 tty，而继承而来的环境指向的是另一个 pane 的 tty。通过 `ctx.bash` 运行会应用部署方的沙箱与策略；插件不拥有任何子进程代码。当 `ctx.bash` 缺失、进程不在真实的 tmux pane 内（`$TMUX_PANE` 未设置，或 tty 不匹配 ⇒ 非零退出）或读取结果格式非法时，本次尝试为空操作，绝不报错。
-
-状态在每个符合条件的轮次拉取——pane 被移动、改名或重新布局都会被感知，无需任何 tmux hook 或后台进程。插件仅在渲染出的 tmux 状态与上次注入不同时才重新注入，因此位置不变时不会新增任何内容。
-
-## 时序语义
-
-当需要注入时，插件在 `step/start` 之前通过 `agent.inject()` 追加一条注入的 `user/message`，来源为 `{ kind: 'plugin', plugin: 'tmux-context' }`。变化抑制与间隔调度会扫描原始持久会话事件中该来源的最近一次注入，因此调度可跨压缩与恢复的进程存续，无需进程内缓存状态；各会话独立调度。该读数记录的是一次请求准备尝试，而非已提交的 step；由于监听器最先运行，当后续 pre-step 监听器取消或失败时，它的追加可能仍会保留（日志只追加，插件不做回滚）。
-
-## 模型体验
-
-### 准备期 tmux 位置
-
-#### 模型看到的内容
-
-在 tmux 状态发生变化的每一轮，注入一条带来源标记、含以下三行的上下文消息。`<window-layout>` 是 tmux 紧凑的 pane 树描述；pane 与 window 的像素尺寸有意省略，相邻 pane 的内容从不采集。
-
-##### 变化轮次读数
-
-```markdown
-tmux location (turn <turn>):
-session <session>, window <index> "<name>", pane <index> <pane-id>
-window active=<0|1>, pane active=<0|1>, layout <window-layout>
-```
-
-#### Token 影响
-
-每条两行读数会累积，直到压缩将其遮蔽。位置未变化以及间隔抑制不会新增内容。
-
-#### KV 缓存影响
-
-只追加；新增可见内容位于可复用的请求前缀之后，不会使已有 KV 缓存条目失效。
-
-## 已知限制与后续工作
-
-- **仅第一个 step**——轮次中途移动或缩放的 pane 会在下一轮反映，而非在 step 之间。
-- **仅自身位置**——插件从不采集相邻 pane 的可见文本。
-- **只有布局，没有尺寸**——省略 pane/window 像素尺寸；仅报告布局树与活动标志。
-- **制表符分隔字段**——若 tmux window 名称包含字面两字符序列 `\t`，会使读数分割错误并作为非法读数跳过；常规名称不受影响。
-- **基于 tty 的 pane 判定**——只有当进程的控制终端与 `$TMUX_PANE` 的 `#{pane_tty}` 一致时，才视为“位于 tmux 中”。这会有意排除从 tmux 祖先进程继承 `$TMUX`／`$TMUX_PANE` 的终端（如 VS Code 集成终端）。`ps -o tty=` 属于 POSIX；在其或 `#{pane_tty}` 不可用的环境中，该检查即为空操作。

 An advisory guard's reminders travel as `additionalContexts` on the `tools/post-execute` decision; the agent loop appends them as logged plugin-sourced `user/message` events after the step's tool results (see [the tools package](../core/tools)), so everything such a guard says to the model is reconstructable from the session log. An enforcing guard instead decides on `tools/pre-execute`, where a `deny` becomes the call's error result and the operation never dispatches.

-English | [中文](README.zh.md)

-An enforcement gate, not a model-facing tool: it never appears in the tool list and adds exactly one behavior — it denies a `write` or `edit` whose target sits inside the dsh checkout the running harness was launched from, on that checkout's own branch, until the calling session's durable log shows a successful load of the `dsh-customize` skill. That skill requires personal changes to be implemented in a task worktree and integrated under the staging lock; this plugin turns its central rule ("do not edit the personal staging checkout directly") from prompt guidance into a boundary the model cannot cross by forgetting.
-
-## Config
-
-```yaml
-- id: source-guard
-  name: '@deepseek-ai/dsh-source-guard'
-  config:
-    requiredSkill: dsh-customize          # default; the skill whose load lifts the denial
-    tools: [write, edit]                  # default; the gated tool names
-    protectedCheckout: /path/to/checkout  # defaults to this module's own location
-```
-
-Every field fails loud at plugin load: an empty `tools` list, a blank `requiredSkill`, or a relative `protectedCheckout` throws, never a silent fall-back.
-
-`protectedCheckout` names a path inside the checkout to guard, and its worktree supplies BOTH protected identities: the repository and the exact branch. Its default is this module's own file, which resolves the checkout the running harness was launched from — the live deployment, whatever its branch is named. Nothing about the branch is configured or pattern-matched, so a maintainer whose staging branch follows no naming convention is protected identically. A harness running from an installed copy resolves a different repository, or none, and therefore guards nothing; the rule is meaningless outside a source checkout.
-
-The shipped TUI composition (`apps/cli/base.cordis.yml`) loads this plugin with defaults. It is inert for anyone whose workspace is not the launcher's own checkout, so an ordinary project sees no change.
-
-## Which paths are protected
-
-Protection is decided by git identity read from files — `.git`, its `gitdir:` pointer, and `HEAD` — never by path prefix and never by running `git`. Prefix matching would be wrong here: the task worktrees the skill prescribes live *inside* the staging tree, at `<staging>/.worktrees/...`, and are exactly where edits belong.
-
-Resolution walks OUTWARD from the target and stops at the first enclosing worktree, so it reports the INNERMOST one. Denial needs that worktree to match the launcher's on BOTH identities: the same shared git directory and the same branch. A task worktree nested under the protected tree answers with its own task branch and passes; the launcher's own tree answers with the launcher's branch and is denied. Repository identity is compared on symlink-resolved paths, so two routes to one repository — a session cwd under `/var/...` and a configured path under `/private/var/...` on macOS — match rather than falling open.
-
-Requiring the exact branch, not a name pattern, keeps the gate on the live deployment only. A stale sibling checkout left by an earlier install shares the repository but runs no launcher, so the workflow rule does not apply to it and it stays editable.
-
-A `gitdir:` pointer may be absolute (what `git worktree add` writes) or relative, which git resolves against the worktree directory holding it; both resolve here. A relative `file_path` resolves against the calling session's workspace, exactly as the filesystem tools resolve it, so it is not an unguarded route to a protected file.
-
-The gate is deliberately narrow:
-
-- **`read` is never gated.** Inspecting the staging checkout violates nothing, so only mutating tools are candidates.
-- **`bash` is not gated.** Reliably classifying mutating shell commands is out of scope, so a determined model can still change staging through a shell.
-- **Calls without an agent are allowed.** A direct `ctx.tools.execute()` caller has no session to replay and no model to correct.
-- **Unresolvable git state fails OPEN.** A path outside any worktree, a detached HEAD on either side, a different repository or branch, a malformed `.git` pointer, or unreadable metadata all leave the call to the rest of the chain. A gate that blocked every write whenever git identity was unavailable would cause more harm than the violation it prevents.
-- **An unresolvable target is not judged.** An empty `file_path`, a non-string one, or a relative one in a session that names no workspace leaves the call to the tool's own validation.
-
-Worktree identity is cached per target directory for the plugin's lifetime, so repeated writes in one directory read git metadata once; a mid-session branch switch is therefore not observed.
-
-## How the denial lifts
-
-Satisfaction is replayed from the session's durable log: a `tool/call` naming the `skill` tool whose arguments parse to `{name: <requiredSkill>}`, paired by call id with a non-error `tool/result`. Because the log is the only state, satisfaction survives a session resume — a resumed session that already loaded the skill is not asked again. A failed load, a differently-named skill, and malformed argument JSON all leave the denial in place.
-
-Satisfaction is per session, so a subagent with its own session must load the skill itself.
-
-## Enforcement point
-
-The gate is a `tools/pre-execute` listener returning `{kind: 'deny', reason}`, so the call never dispatches and the file is never touched. It delegates via `next()` in every non-violating case. Denial — not an advisory reminder — is the point: an advisory nudge leaves the violation committed, and `ask` degrades to denial in a composition without approval support.
-
-## Testing
-
-Unit suites drive a real agent loop against a mock adapter over real git-metadata fixtures — a staging worktree, a task worktree nested inside it, a plain clone, a foreign repository on a staging-named branch, a detached HEAD, absolute and relative `gitdir:` pointers, a symlinked route to the same repository, and unreadable metadata — to per-file 100%. The assembled-run evidence is the Loader-composition smoke (`tests/loader-composition.e2e.ts`): it boots a real headless app over `examples/headless-agent/tests/fixtures/guard/source-guard/cordis.yml`, seeds a staging worktree in a temporary cwd, and asserts the tool result is an error carrying the exact denial while the targeted file keeps its original bytes.
-
-## Model Experience
-
-### Denied filesystem call
-
-#### What the model sees
-
-A gated call into a protected worktree without the required skill loaded returns an error result carrying exactly the text below. No prompt section, tool schema, or successful-call text is added, and an allowed call is indistinguishable from one made without this plugin.
-
-##### Denial result
-
-```markdown
-Error: Editing "<path>" directly is not allowed: it is inside the dsh checkout this session is running from, on branch <branch>. Load the <requiredSkill> skill first and follow it — implement in a task worktree, then integrate under the staging lock.
-```
-
-#### Token effect
-
-Zero tokens while no denial occurs. A denial adds its small retained error result and avoids the success payload the call would have produced.
-
-#### KV Cache effect
-
-Append-only; newly visible content follows the reusable request prefix and does not invalidate existing KV-cache entries.
-
-## Known Limitations and Deferred Work
-
-- **`bash` is ungated** — the guard is a boundary for the filesystem tools only; a shell command can still mutate a protected worktree.
-- **Worktree identity is cached per directory for the plugin's lifetime** — switching a protected worktree's branch mid-session does not change decisions until the next load, on either the target or the launcher side.
-- **Only the launcher's own checkout is protected** — a stale sibling checkout of the same repository stays editable, deliberately; run `dsh` from it to protect it.
-- **Disarmed outside a source checkout** — a harness running from an installed copy protects nothing unless `protectedCheckout` names a real checkout explicitly.
-- **Satisfaction is per session** — a subagent's session must load the skill itself; a parent's load does not carry over.
-- **Fail-open on unresolvable git state** — a broken or unreadable `.git` means no protection, chosen deliberately over blocking every edit.
-- **One skill lifts the whole gate for the session** — loading it does not verify the workflow was actually followed, only that the instructions were read.

-# @deepseek-ai/dsh-source-guard
-
-[English](README.md) | 中文
-
-这是一道强制执行门禁，而非面向模型的工具：它不会出现在工具列表中，只增加一种行为。若 `write` 或 `edit` 的目标位于运行中 harness 启动来源的 dsh 检出目录内，并处于该检出目录自身的分支上，它会拒绝调用，直到调用方会话的持久日志表明已成功加载 `dsh-customize` skill（技能）。该 skill 要求在任务 worktree 中实现个人变更，并在 staging 锁保护下完成集成；本插件把其核心规则（「不要直接编辑个人 staging 检出目录」）从提示词指导变成一道模型无法因遗忘而越过的边界。
-
-## 配置
-
-```yaml
-- id: source-guard
-  name: '@deepseek-ai/dsh-source-guard'
-  config:
-    requiredSkill: dsh-customize          # default; the skill whose load lifts the denial
-    tools: [write, edit]                  # default; the gated tool names
-    protectedCheckout: /path/to/checkout  # defaults to this module's own location
-```
-
-插件加载时，每个字段都会对错误配置快速失败：`tools` 为空列表、`requiredSkill` 为空白字符串，或 `protectedCheckout` 使用相对路径时，都会抛出错误，绝不静默回退。
-
-`protectedCheckout` 指定位于待保护检出目录内的一条路径；其 worktree 会提供两项受保护身份：仓库和确切分支。其默认值是本模块自己的文件，由此解析出运行中 harness 启动来源的检出目录——当前运行的部署，无论其分支采用什么名称。分支既无需配置，也不会通过模式匹配，因此 staging 分支不遵循任何命名约定的维护者同样会受到保护。若 harness 从已安装副本运行，则会解析到另一个仓库，或根本解析不到仓库，因此不会保护任何内容；这条规则在源码检出目录之外没有意义。
-
-已交付的 TUI 组合（`apps/cli/base.cordis.yml`）会以默认配置加载本插件。若用户的工作区并非启动器自身所在的检出目录，本插件不会生效，因此普通项目不会发生任何变化。
-
-## 受保护的路径
-
-保护范围根据从文件读取的 Git 身份确定，即 `.git`、其中的 `gitdir:` 指针和 `HEAD`；既不按路径前缀判断，也不运行 `git`。此处若匹配路径前缀就会出错：skill 要求使用的任务 worktree 位于 staging 树*内部*的 `<staging>/.worktrees/...`，而这正是应该进行编辑的位置。
-
-解析过程从目标路径开始向外逐层查找，遇到第一个所属 worktree 就停止，因此返回最内层的 worktree。只有该 worktree 在两项身份上都与启动器的 worktree 匹配，才会拒绝：共用同一个共享 Git 目录，且分支相同。嵌套在受保护树下的任务 worktree 会返回自己的任务分支并获准；启动器自身所在的树会返回启动器的分支并被拒绝。仓库身份会按解析符号链接后的路径进行比较，因此指向同一仓库的两条路径——macOS 上位于 `/var/...` 下的会话 cwd 和位于 `/private/var/...` 下的配置路径——会相互匹配，而不会触发故障放行（fail-open）。
-
-要求匹配确切分支而非名称模式，可确保门禁仅作用于当前运行的部署。先前安装留下的陈旧同级检出目录虽然共享仓库，却没有运行启动器，因此该工作流规则不适用于它，它仍可编辑。
-
-`gitdir:` 指针既可以是绝对路径（`git worktree add` 写入的形式），也可以是相对路径；Git 会以包含该指针的 worktree 目录为基准解析相对路径，本插件对两者都能解析。相对 `file_path` 会像文件系统工具一样，相对于调用会话的工作区解析，因此不会成为绕过门禁访问受保护文件的路径。
-
-门禁刻意保持较窄的范围：
-
-- **`read` 从不受门禁限制。** 检查 staging 检出不构成违规，因此只有修改类工具是候选项。
-- **`bash` 不受门禁限制。** 可靠识别会修改内容的 shell 命令不在范围内，因此执意修改的模型仍可通过 shell 修改 staging。
-- **没有 agent（智能体）的调用会被放行。** 直接调用 `ctx.tools.execute()` 的调用方没有可供回放的会话，也没有需要纠正的模型。
-- **无法解析 Git 状态时故障放行。** 不属于任何 worktree 的路径、任一侧的 HEAD 分离状态、其他仓库或分支、格式错误的 `.git` 指针或不可读的元数据，都会把调用交给链中后续环节处理。若每逢 Git 身份不可用就阻止所有写入，这道门禁造成的危害将大于它所防止的违规。
-- **无法解析的目标不会被判断。** `file_path` 为空、不是字符串，或它是相对路径而会话未指定工作区时，调用会交给工具自身校验。
-
-插件会在其整个生命周期内按目标目录缓存 worktree 身份，因此同一目录中的重复写入只读取一次 Git 元数据；由此，系统不会观察到会话中途的分支切换。
-
-## 如何解除拒绝
-
-是否满足解锁条件由会话的持久日志回放得出：日志中存在一条 `tool/call`，它调用名为 `skill` 的工具，参数可解析为 `{name: <requiredSkill>}`，并且有一条调用 id 相同的非错误 `tool/result` 与之配对。由于日志是唯一状态源，恢复会话时仍能保留这一结果：若恢复的会话已经加载该 skill，系统不会再次要求加载。加载失败、skill 名称不同或参数 JSON 格式错误，都会让拒绝继续生效。
-
-解锁条件按会话独立满足，因此拥有独立会话的 subagent 必须自行加载该 skill。
-
-## 强制执行点
-
-门禁是一个 `tools/pre-execute` 监听器，返回 `{kind: 'deny', reason}`，因此调用绝不会分派执行，文件也绝不会被修改。在所有不违规的情况下，它都会通过 `next()` 委派。这里刻意采用拒绝而非建议性提醒：建议性提醒仍会让违规落地，而在不支持批准的组合中，`ask` 会退化为拒绝。
-
-## 测试
-
-单元测试套件基于真实 Git 元数据 fixture（测试前置数据），使用 mock 适配器驱动真实 agent loop（智能体循环）：覆盖 staging worktree、嵌套其中的任务 worktree、普通克隆、位于 staging 命名分支上的其他仓库、HEAD 分离状态、绝对和相对 `gitdir:` 指针、指向同一仓库的符号链接路径以及不可读元数据，达到逐文件 100% 覆盖率。组装运行层面的证据来自 Loader 组合冒烟测试（`tests/loader-composition.e2e.ts`）：它通过 `examples/headless-agent/tests/fixtures/guard/source-guard/cordis.yml` 启动一个真实的 headless 应用，在临时 cwd 中植入 staging worktree，并断言工具结果是携带精确拒绝文本的错误，同时目标文件保持原始字节不变。
-
-## 模型体验
-
-### 被拒绝的文件系统调用
-
-#### 模型看到的内容
-
-如果未加载必需 skill 就对受保护 worktree 发起受门禁限制的调用，系统会返回错误结果，其中的文本与下文完全一致。系统不会添加提示词段、工具 schema 或成功调用文本；允许的调用与未启用此插件时的调用完全无法区分。
-
-##### 拒绝结果
-
-```markdown
-Error: Editing "<path>" directly is not allowed: it is inside the dsh checkout this session is running from, on branch <branch>. Load the <requiredSkill> skill first and follow it — implement in a task worktree, then integrate under the staging lock.
-```
-
-#### Token 影响
-
-未发生拒绝时为零 token。一次拒绝会添加一条会保留在历史中的短小错误结果，同时避免生成该调用原本会产生的成功载荷。
-
-#### KV Cache 影响
-
-仅追加；新出现的内容位于可复用请求前缀之后，不会使现有 KV-cache 条目失效。
-
-## 已知限制与暂缓工作
-
-- **`bash` 不受门禁限制**：此插件只为文件系统工具提供边界；shell 命令仍可修改受保护的 worktree。
-- **插件生命周期内按目录缓存 worktree 身份**：在会话中途切换受保护 worktree 的分支，不会改变判断结果，直至下次加载插件；目标侧和启动器侧都是如此。
-- **仅保护启动器自身的检出目录**：同一仓库中的陈旧同级检出目录会被刻意保留为可编辑状态；若要保护它，请从中运行 `dsh`。
-- **源码检出之外不启用**：从已安装副本运行的 harness 不保护任何内容，除非 `protectedCheckout` 明确指定真实检出目录。
-- **解锁条件按会话独立满足**：subagent 的会话必须自行加载该 skill；父会话的加载状态不会继承。
-- **无法解析 Git 状态时故障放行**：损坏或不可读的 `.git` 会使保护失效；这是刻意选择的结果，因为另一方案是阻止所有编辑。
-- **仅加载一个 skill 即可为会话解除整道门禁**：加载该 skill 并不能验证是否实际遵循工作流，只能证明已阅读这些指令。

 ## Consequences
 
 - Sessions already stored under a project-local `./.sessions` disappear from `/resume`. This is the accepted cost of no migration.
-- One shared root makes the pre-existing absence of a cross-process session lock reachable in one step: colliding used to require two terminals in the same directory, and is now one Tab away. `record.live` comes from the in-process `SessionQueryService`, so preflight rejects only sessions live in *this* runtime, while the JSONL backend takes no lock and two processes appending one log with independent `seq` counters would interleave. Closing this is no longer speculative hardening: `SessionRegistry.list()` already publishes live sessions cross-process under the same Harness home for `dsh list-sessions`, so consulting it in `summarizeResumeCandidate` is a small follow-up. It stays out of this change as pre-existing scope.
 - A resumed session can change the process's working directory, so a foreign resume is not a pure transcript restoration — every path-resolving tool moves with it.
 - The Harness home now holds session logs for every project on the machine. Its growth is no longer bounded by one checkout, and no retention policy is introduced here.

 ## Consequences
 
 - 已经存放在项目本地 `./.sessions` 下的会话会从 `/resume` 中消失。这是不做迁移所接受的代价。
-- 同一个共享根目录让原本就缺失的跨进程会话锁一步之内即可触达：过去要造成冲突需要在同一个目录里开两个终端，如今只差一次 Tab。`record.live` 来自进程内的 `SessionQueryService`，因此预检只会拒绝在*本*运行时中处于活跃状态的会话，而 JSONL 后端不加任何锁，两个进程用各自独立的 `seq` 计数器追加同一份日志会互相交错。解决这一点已不再是投机性加固：`SessionRegistry.list()` 已经为 `dsh list-sessions` 在同一个 Harness home 下跨进程发布活跃会话，因此在 `summarizeResumeCandidate` 中查询它是一项小的后续工作。它作为既有范围之外的问题不纳入本次改动。
 - 恢复一个会话可以改变进程的工作目录，因此恢复外部会话不是单纯的 transcript 还原——每个解析路径的工具都会随之移动。
 - Harness home 现在保存着这台机器上每个项目的会话日志。它的增长不再受单个 checkout 约束，而本记录也没有引入任何保留策略。

-# Agent Note: live-session registry and `dsh list-sessions`
-
-Status: implemented
-
-English | [中文](2026-07-28-live-session-registry-and-dsh-ls.zh.md)
-
-## Problem
-
-Nothing could answer "which dsh sessions am I running right now". A user with sessions across several projects had no way to enumerate them, and no way to recover the id needed for `--resume` except the exit line of the terminal that printed it. Session persistence records every session that ever existed, so it cannot answer the question: it has no notion of liveness, and no `process.pid` appeared anywhere in the session, persistence, or storage packages.
-
-## Decision
-
-`dsh list-sessions` (alias `dsh ps`) lists the sessions running right now — session id, pid, uptime, workspace, title — newest first, across every workspace, with `--json` for machines. Three packages back it, as a capability seam.
-
-[`dsh-session-registry`](../../../../packages/session-registry/session-registry/README.md) (`ctx.sessionRegistry`) is the seam: the abstract service contract and record vocabulary, so the medium can later move to a database without touching consumers. [`dsh-session-registry-file`](../../../../packages/session-registry/session-registry-file/README.md) implements it over one lock-guarded JSON file under the Harness home. [`dsh-session-registry-live`](../../../../packages/session-registry/session-registry-live/README.md) follows `session/created`, `session/disposed`, and `session/title` and keeps the registry in step. `apps/cli` mounts both on every launcher surface — the TUI, `dsh meta`, headless, and web — and `dsh list-sessions` mounts only the service, booting no agent tree. No surface label is recorded: a launcher's mode is not a property of the session, and the workspace column already distinguishes a `dsh meta` session from a project one.
-
-### Liveness is derived, never stored
-
-`list()` probes each record's pid with `kill(pid, 0)` and drops the dead ones, writing the pruned result back. A process killed without running its disposer leaves a record that the next read removes, so there is no daemon, no heartbeat, and no permanent phantom. A per-process `bootId` distinguishes a recycled pid, so deregistration cannot delete a namesake record from a different incarnation. `EPERM` counts as alive: a live session owned by another user must not be dropped.
-
-### Two independent concurrency layers
-
-The file is written by every dsh process and by several sessions inside one process, and the two cases need different mechanisms.
-
-Across processes, each read-modify-write holds a [`proper-lockfile`](https://github.com/moxystudio/node-proper-lockfile) advisory lock. Within one process, calls queue on an internal chain, because the advisory lock is tracked per process: overlapping same-process callers contend for its bounded retry budget rather than queueing, and past roughly a dozen concurrent calls that budget runs out and a registration rejects. Since publication is fire-and-forget, such a rejection silently drops a live session from the listing — the exact "listing that lies" failure this feature exists to avoid. Both layers are load-bearing and each is pinned by a test that fails without it.
-
-### Records carry their own title
-
-The title is the one mutable field, replaced through `retitle` as `session/title` events arrive. It lives in the record rather than being read from the session log because the log's location, format, and compression are per-deployment backend choices: the TUI writes project-local zstd-compressed JSONL, the web and headless surfaces write to a global root, a user profile overrides either, and SQLite has no per-session file at all. An independent reader cannot portably parse that, so `dsh list-sessions` opens no log and assumes no backend.
-
-### Subagents are invisible by construction
-
-Only top-level launcher surfaces mount the publisher. In-process subagents (`spawn`, `fork`) have no process of their own, and the out-of-process backends spawn `dsh-jsonrpc-agent` rather than this CLI. No filter flag is needed, and no subagent package changed.
-
-## Alternatives considered
-
-**One file per session under `~/.dsh/run/`.** No lock at all, since each process only writes and deletes its own file. Rejected in favour of the single file the user chose, which then made a real advisory lock mandatory rather than optional.
-
-**A domain over the `storage-json` backend.** The obvious reuse, and wrong: that backend documents "no cross-process write locking … last write wins" and names single-host-process as its assumption, and the [domain KV storage note](../../proposed/architecture/2026-07-24-domain-kv-storage-and-workspace.md) puts multi-process explicitly out of scope. A registry written concurrently by every launcher is precisely that excluded case. Widening the backend's contract would have changed a shipped guarantee for one consumer; a separate package owns the multi-process medium instead.
-
-**Hand-rolled `O_EXCL` lock directory.** Rejected under the [dependencies-over-hand-rolling policy](../process/2026-07-26-dependencies-over-hand-rolling.md): stale-lock detection, retry backoff, and compromise handling are exactly the surface a maintained dependency should own.
-
-**Accept last-write-wins on the single file.** Cheapest to build, and it silently omits real running sessions when two start close together. A listing tool that lies is worse than no listing tool.
-
-**Read the title from the session log in `dsh list-sessions`.** Implemented first, then verified live: the shipped TUI writes `session.jsonl.zstd`, whose frame helpers are internal to the jsonl backend. Exporting them would have hard-coded one backend's file format into the CLI and still shown nothing for SQLite.
-
-**Register the web server itself with a placeholder session id.** `dsh web` owns no session — its sessions are created later by browser clients — so a server row would have put a fake id in a session table. Following session lifecycle instead makes browser sessions appear and disappear as they are opened, which also subsumed the TUI's launcher-side registration and deleted that separate path.
-
-**A `--here`/`--workspace` filter.** Dropped on request: the listing is always global, and narrowing is the user's `grep`.
-
-## Consequences
-
-The registry is an observability aid, so every write is best-effort: a registry fault warns and never fails a working agent session. The cost is that a listing can lag reality by one failed write, healed by the next.
-
-Title mirroring costs one locked read-modify-write per revision, so an aggressive retitling cadence pays that write each time.
-
-`bootId` bounds pid reuse only for records this process wrote. A foreign record whose pid the operating system has reassigned to an unrelated live process is reported alive until its owner removes it — accepted because the portable alternative, reading real process start times, is `/proc`-only.
-
-Liveness is pid existence, not health: a hung process still lists as running. The registry deliberately makes no progress judgement.
-
-## Testing
-
-Unit coverage pins durable-format validation (torn text, foreign version, per-row damage that must not hide siblings), pid pruning against a genuinely reaped pid, `EPERM`-is-alive, incarnation-scoped deregistration, and `retitle` scoping. Both concurrency layers have a regression test verified to fail when its mechanism is removed: 8 real processes for the cross-process lock, 24 overlapping in-process calls for the chain. The publisher is tested over the real `SessionStore` rather than a hand-built emitter, because publication depends on the store's actual lifecycle dispatch.
-
-Verified live in tmux against the assembled application: two concurrent TUI sessions in different workspaces both listed, a title appeared after the first turn, clean exit deregistered, and `SIGKILL` left a stale record that the next `dsh list-sessions` pruned and durably rewrote.

-## 问题
-
-没有任何东西能回答「我此刻正在运行哪些 dsh 会话」。会话散落在多个项目中的用户既无法枚举它们，也无法找回 `--resume` 所需的 id，唯一的来源是打印过它的那个终端的退出行。会话持久化记录了曾经存在过的每个会话，因此它答不了这个问题：它没有存活状态的概念，而且 session、persistence、storage 这几个包里任何位置都没有出现过 `process.pid`。
-
-## 决策
-
-`dsh list-sessions`（别名 `dsh ps`）列出此刻正在运行的会话（会话 id、pid、运行时长、工作区、标题），最新的排在最前，覆盖所有工作区，并提供面向机器的 `--json`。背后由三个包（package）以能力 seam 的形式支撑。

-[`dsh-session-registry`](../../../../packages/session-registry/session-registry/README.md)（`ctx.sessionRegistry`）是 seam：抽象服务契约与记录词汇，使介质将来可以换成数据库而不触及消费方。[`dsh-session-registry-file`](../../../../packages/session-registry/session-registry-file/README.md) 在 Harness home 下的一个加锁保护的 JSON 文件上实现它。[`dsh-session-registry-live`](../../../../packages/session-registry/session-registry-live/README.md) 跟随 `session/created`、`session/disposed` 和 `session/title`，让注册表保持同步。`apps/cli` 在每个启动方接口（TUI、`dsh meta`、headless、web）上都挂载这两个包，而 `dsh list-sessions` 只挂载该服务，不启动任何 agent（智能体）树。不记录任何接口标签：启动方的模式并不是会话的属性，而工作区那一列已经能把 `dsh meta` 会话和项目会话区分开。
-
-### 存活状态是推导出来的，绝不存储
-
-`list()` 用 `kill(pid, 0)` 探测每条记录的 pid，剪除已消亡的记录，并把剪除后的结果写回。未运行 disposer（资源释放）就被杀掉的进程留下的记录，会被下一次读取移除，因此不需要 daemon，不需要心跳，也不会有永久残留的幽灵记录。每个进程独有的 `bootId` 用于区分被复用的 pid，因此注销不会删除属于另一个 incarnation 的同名记录。`EPERM` 算作存活：归属于另一个用户的存活会话绝不能被丢掉。
-
-### 两层相互独立的并发机制
-
-该文件既被每个 dsh 进程写入，也被同一进程内的多个会话写入，这两种情形需要不同的机制。
-
-跨进程时，每次读-改-写都持有一个 [`proper-lockfile`](https://github.com/moxystudio/node-proper-lockfile) 咨询锁。进程内则由各次调用在内部链上排队，因为咨询锁是按进程跟踪的：同一进程中重叠的调用方会争抢它有界的重试预算，而不是排队等待；大约超过十几次并发调用后，该预算耗尽，某次注册就会被拒绝。由于发布采用 fire-and-forget 方式，这样一次拒绝会静默地把一个存活会话从列表中丢掉——而这正是本功能要避免的「列表说谎」故障。两层机制都是必需的，且各有一个测试固定它：移除该机制，对应测试就会失败。
-
-### 记录自带标题
-
-标题是唯一的可变字段，随 `session/title` 事件到达，通过 `retitle` 替换。它存放在记录里，而不是从会话日志读取，因为日志的位置、格式和压缩都是逐部署的后端选择：TUI 写入项目本地的 zstd 压缩 JSONL，web 与 headless 界面写入全局根目录，用户配置文件可以覆盖二者，而 SQLite 根本没有逐会话的文件。独立读取方无法以可移植的方式解析这些内容，因此 `dsh list-sessions` 不打开任何日志，也不假定任何后端。
-
-### subagent 在设计上就不可见
-
-只有顶层启动方接口才挂载发布方。进程内 subagent（`spawn`、`fork`）没有自己的进程，而进程外后端 spawn 的是 `dsh-jsonrpc-agent` 而不是本 CLI（命令行界面）。不需要任何过滤开关，也没有改动任何 subagent 包。
-
-## 考虑过的替代方案
-
-**在 `~/.dsh/run/` 下每个会话一个文件。** 完全不需要锁，因为每个进程只写入和删除自己的文件。不予采纳，改用用户选定的单文件方案，而这也使真正的咨询锁从可选变为必需。
-
-**在 `storage-json` 后端之上做一个 domain。** 这是最显而易见的复用，但它是错的：该后端明确记载「无跨进程写锁……最后写入者胜出」，并把单一宿主进程列为自身前提，而[domain KV 存储 note](../../proposed/architecture/2026-07-24-domain-kv-storage-and-workspace.md)明确把多进程排除在范围之外。被每个启动方并发写入的注册表恰恰就是这个被排除的场景。放宽该后端的契约，等于为一个消费方改动一项已上线的保证；改由一个独立的包拥有这套多进程介质。
-
-**手写 `O_EXCL` 锁目录。** 依据[优先使用依赖而非手写政策](../process/2026-07-26-dependencies-over-hand-rolling.md)不予采纳：陈旧锁检测、重试退避和受损处理，恰恰是应当由一个有人维护的依赖拥有的那部分工作。
-
-**在单文件上接受最后写入者胜出。** 这是最省事的实现，但当两个会话相近时间启动时，它会静默漏掉真实运行中的会话。一个会说谎的列表工具比没有列表工具更糟。
-
-**在 `dsh list-sessions` 中从会话日志读取标题。** 该方案先落地实现，随后经实机验证否决：上线的 TUI 写入 `session.jsonl.zstd`，其帧处理辅助函数是 jsonl 后端的内部实现。把它们导出，等于把某一个后端的文件格式硬编码进 CLI，而且对 SQLite 仍然什么都显示不出来。
-
-**用占位会话 id 注册 web 服务器本身。** `dsh web` 不拥有任何会话（它的会话由浏览器客户端稍后创建），因此一行服务器记录会把一个假 id 放进会话表。改为跟随会话生命周期后，浏览器会话会随打开与关闭而出现和消失，这同时也涵盖了 TUI 启动方一侧的注册，并删除了那条独立路径。
-
-**加一个 `--here`/`--workspace` 过滤开关。** 按要求放弃：列表始终是全局的，收窄范围交给用户自己的 `grep`。
-
-## 后果
-
-注册表是一项可观测性辅助设施，因此每次写入都是尽力而为：注册表故障只发出警告，绝不让正常工作的 agent 会话失败。代价是列表可能因一次失败的写入而落后于现实一步，并由下一次写入修复。
-
-标题镜像每次修订都要付出一次加锁的读-改-写，因此改名节奏激进时，每次改名都要付出这一次写入。
-
-`bootId` 只对本进程写入的记录约束 pid 复用。如果一条外来记录的 pid 已被操作系统重新分配给一个无关的存活进程，那么在其所有者移除它之前，该记录会被报告为存活——之所以接受，是因为可移植的替代方案（读取进程真实启动时间）仅在 `/proc` 上可用。
-
-存活状态只表示 pid 存在，不表示健康：挂死的进程仍会被列为正在运行。注册表刻意不对进展作出判断。
-
-## 测试
-
-单元覆盖固定了持久格式校验（截断文本、外来版本、不得遮蔽同级记录的单条损坏）、针对真正已回收 pid 的剪除、`EPERM` 算存活、按 incarnation 限定范围的注销，以及 `retitle` 的作用范围。两层并发机制各有一个回归测试，且都已验证在移除对应机制后会失败：跨进程锁用 8 个真实进程，进程内链用 24 次重叠调用。发布方在真实的 `SessionStore` 上测试，而非手搭的事件发射器，因为发布依赖该 store 实际的生命周期派发。
-
-已在 tmux 中针对组装后的应用实机验证：位于不同工作区的两个并发 TUI 会话都被列出，第一轮之后出现标题，正常退出完成注销，而 `SIGKILL` 留下的陈旧记录被下一次 `dsh list-sessions` 剪除并持久重写。

-# session-registry/ — live-session registry family

-| [`session-registry-live/`](session-registry-live/README.md) | Publisher: follows session lifecycle and title events, keeping the registry in step | — |
-
-The split follows the three-package capability-seam convention: the seam answers "what is live" for a short-lived reader that mounts nothing else, the file backend owns today's medium and can be replaced by a database without touching consumers, and the publisher needs the session store and runs inside a full agent composition. Liveness is derived from the recorded pid at read time rather than stored, so a killed process leaves nothing to clean up. Records carry their own title because log location, format, and compression are per-deployment backend choices an independent reader cannot portably parse.
-
-This family is independent of session persistence: it records which processes hold which sessions, never conversation content, and a session that is never persisted still lists.

-# session-registry/：活跃会话注册表家族

-
-这样拆分遵循由三个包构成的能力 seam 惯例：seam 要回答「哪些会话是活跃的」，供一个不挂载其他任何东西的短生命周期读取方使用；文件后端拥有今天的介质，将来可以换成数据库而不触及消费方；发布方需要会话存储，运行在完整的 agent（智能体）组合体内。存活状态在读取时由记录的 pid 推导，而不是存下来，因此进程被杀掉后不留下任何需要清理的东西。记录自带标题，因为日志位置、格式和压缩都是各部署自行选择的后端方案，独立的读取方无法以可移植的方式解析。
-
-这个家族与会话持久化相互独立：它只记录哪些进程持有哪些会话，绝不记录对话内容；从未被持久化的会话同样能被列出。

-# @deepseek-ai/dsh-session-registry-file
-
-English | [中文](README.zh.md)
-
-File-backed implementation of the [live-session registry seam](../session-registry/README.md): one lock-guarded JSON file under the Harness home is the whole medium. Mounting it publishes `ctx.sessionRegistry`; `file` exposes the absolute registry path (`<root>/sessions.json`).
-
-## Liveness and crash safety
-
-Liveness is derived at read time from the recorded pid via `kill(pid, 0)`: `ESRCH` is dead, `EPERM` is alive under another user, and any other errno propagates rather than being read as an answer. A process killed without running its disposer therefore leaves a record that the next `list()` prunes and rewrites — no daemon, no heartbeat, and no permanent phantom. `bootId` distinguishes a recycled pid, so deregistration cannot delete a namesake record belonging to a different incarnation.
-
-## Concurrency
-
-Both layers are required and neither substitutes for the other.
-
-- **Across processes**, each read-modify-write cycle holds a [`proper-lockfile`](https://github.com/moxystudio/node-proper-lockfile) advisory lock. Unlocked whole-file republication loses records under concurrent launchers, which is why the storage-hub JSON backend — documented last-write-wins, single-host-process — cannot serve this medium.
-- **Within one process**, calls queue on an internal chain. The advisory lock is tracked per process, so overlapping same-process callers contend for its bounded retry budget instead of queueing; past roughly a dozen concurrent calls that budget runs out and a registration rejects. Callers publish fire-and-forget, so such a rejection would silently drop a live session from the listing.
-
-Writes are temp-file plus atomic `rename` (no fsync: a listing lost to a crash is rebuilt by the next process's read, so crash durability buys nothing here), under a `0o700` root with a `0o600` file.
-
-## Durable format
-
-`sessions.json` carries a `version` stamp pinned at `0` under the pre-release stance: a differing version is rejected rather than migrated. Reads validate every field because the medium is shared and user-visible. An individually unusable row is dropped while its siblings survive, and unparsable text or a foreign version reads as empty — one malformed record written by another harness version must not hide every other live session. Any of these marks the medium damaged, so the next write republishes and heals it.
-
-## Config
-
-| Key | Type | Default | Meaning |
-| --- | --- | --- | --- |
-| `root` | string | required — no default (a cwd fallback would scatter registries) | Directory holding `sessions.json`; created `0o700` on demand |
-| `lockStaleMs` | natural | `10000` | Milliseconds after which a held lock is treated as abandoned and reclaimed |
-| `lockRetries` | natural | `10` | Retries before a contended acquisition fails loud |
-
-## Model Experience
-
-None, as this package registers no tools, injects no prompts, and appends no session events; it stores host-side process records for the CLI listing surface only.
-
-#### KV Cache effect
-
-Independent of live requests: the registry never touches a request prefix, so nothing here can invalidate provider cache reuse.
-
-## Known Limitations and Deferred Work
-
-- **A reused pid within the stale window is trusted** — `bootId` distinguishes incarnations of records this process wrote, but a foreign record whose pid the operating system has since reassigned to an unrelated live process is reported alive until its owner removes it.

-
-[English](README.md) | 中文
-
-[存活会话注册表 seam](../session-registry/README.md) 的文件后端实现：整套介质就是 Harness home 下的一个加锁保护的 JSON 文件。挂载它即发布 `ctx.sessionRegistry`；`file` 暴露注册表文件的绝对路径（`<root>/sessions.json`）。
-
-## 存活状态与崩溃安全
-
-存活状态在读取时由记录的 pid 经 `kill(pid, 0)` 推导：`ESRCH` 表示已消亡，`EPERM` 表示存活于另一个用户之下，其他任何 errno 都向外抛出，而不会被当成一个答案来解读。因此，未运行 disposer 就被杀掉的进程留下的记录，会被下一次 `list()` 剪除并重写——不需要 daemon，不需要心跳，也不会有永久残留的幽灵记录。`bootId` 用于区分被复用的 pid，因此注销不会删除属于另一个 incarnation 的同名记录。
-
-## 并发
-
-两层机制都是必需的，任何一层都无法替代另一层。
-
-- **跨进程**：每个读改写周期都持有 [`proper-lockfile`](https://github.com/moxystudio/node-proper-lockfile) 咨询锁。无锁的全文件重发布会在并发启动器下丢失记录，这正是 storage-hub JSON 后端（文档声明 last-write-wins、单宿主进程）无法承担该介质的原因。
-- **进程内**：调用在内部链上排队。咨询锁按进程跟踪，因此同进程的重叠调用者会争用其有限的重试预算而非排队；并发调用超过十来个时预算耗尽，注册会被拒绝。调用方以 fire-and-forget 方式发布，这样的拒绝会静默地把一个存活会话从列表中丢掉。
-
-写入采用临时文件加原子 `rename`（不做 fsync：崩溃丢失的列表会被下一个进程的读取重建，崩溃持久性在这里没有收益），根目录 `0o700`，文件 `0o600`。
-
-## 持久化格式
-
-`sessions.json` 携带一个 `version` 戳，在预发布立场下固定为 `0`：版本不同将被拒绝而非迁移。由于介质是共享且用户可见的，读取会校验每个字段。单条不可用的行会被丢弃而其同伴保留；无法解析的文本或异版本文件读作空——另一个 harness 版本写入的一条损坏记录，不得隐藏所有其他存活会话。上述任一情况都会把介质标记为受损，下一次写入将重新发布并修复它。
-
-## 配置
-
-| 键 | 类型 | 默认值 | 含义 |
-| --- | --- | --- | --- |
-| `root` | string | 必填——无默认值（回退到 cwd 会使注册表散落各处） | 存放 `sessions.json` 的目录；按需以 `0o700` 创建 |
-| `lockStaleMs` | natural | `10000` | 持有的锁超过该毫秒数即视为被遗弃并被回收 |
-| `lockRetries` | natural | `10` | 锁争用时在明确失败前的重试次数 |
-
-## 模型体验
-
-无。本包不注册工具、不注入提示词、不追加会话事件；它只为 CLI 列表界面存储宿主侧进程记录。
-
-#### KV 缓存影响
-
-与在途请求无关：注册表从不触碰请求前缀，因此这里不会使提供方缓存复用失效。
-
-## 已知限制与后续工作
-
-- **陈旧窗口内被复用的 pid 会被信任**——`bootId` 能区分本进程所写记录的 incarnation，但外来记录的 pid 若已被操作系统重新分配给无关的存活进程，在其属主移除之前会一直被报告为存活。

-# @deepseek-ai/dsh-session-registry-live
-
-English | [中文](README.zh.md)
-
-Publishes every live session in this process into the [session registry](../session-registry/README.md), so `dsh list-sessions` lists the sessions a server creates on demand rather than only the one a launcher minted up front.
-
-## Behavior
-
-Registration follows session lifecycle rather than a launcher-known identity: the plugin publishes every session present at mount and every later `session/created`, and removes a record when its session is disposed. One path therefore serves both the TUI's single session and the browser UI's one-per-conversation sessions.
-
-A session whose header carries no `cwd` is skipped — the listing's workspace column would have nothing truthful to show.
-
-`session/title` events are mirrored onto the record through `retitle`, so the latest logged title reaches the listing. Carrying the title in the record is what keeps the reader backend-agnostic: the log's location, file format, and compression are per-deployment choices (the shipped TUI writes zstd-compressed JSONL), so an independent process cannot portably parse one.
-
-Publication is fire-and-forget with a warning on failure: the registry is an observability aid, so a registry fault must not fail a working agent session. A session that ends while its registration is still in flight leaves a tombstone the completing registration observes, so its record cannot outlive the session until a pid-based prune.
-
-## Config
-
-None. Every published record is derived from the session itself, so no deployment-varying choice is left to configure.
-
-## Model Experience
-
-None, as this package registers no tools, injects no prompts, and appends no session events; it only mirrors existing lifecycle and title events into a host-side process record.
-
-#### KV Cache effect
-
-Independent of live requests: the plugin reads session events and writes a separate registry file without touching any request prefix, so it cannot invalidate provider cache reuse.
-
-## Known Limitations and Deferred Work
-
-- **A skipped session is invisible, not deferred** — a session created without a `cwd` is never published, even if a workspace becomes known later; there is no re-check.
-- **Title mirroring costs one registry write per revision** — each `session/title` event triggers a locked read-modify-write, so a deployment with an aggressive retitling cadence pays that write per revision.

-# @deepseek-ai/dsh-session-registry-live
-
-[English](README.md) | 中文
-
-把本进程内每个活跃会话发布到[会话注册表](../session-registry/README.md)，因此 `dsh list-sessions` 能列出服务端按需创建的所有会话，而不是只列出启动器一开始铸出的那一个。
-
-## 行为
-
-注册跟随会话生命周期，而不依赖启动器已知的身份：插件会发布挂载时已存在的每个会话，以及此后每个 `session/created`，并在会话被 dispose（资源释放）时移除对应记录。因此同一条路径既服务 TUI 的单个会话，也服务浏览器 UI 的每对话一个的多个会话。
-
-会话头不带 `cwd` 时会被跳过：列表的工作区列拿不到任何真实内容可展示。
-
-`session/title` 事件通过 `retitle` 镜像到记录上，因此最新记录的标题能到达列表。把标题带在记录里，正是让读取方与后端无关的原因：日志的位置、文件格式和压缩都是逐部署的选择（随附的 TUI 写入 Zstandard 压缩的 JSONL），因此独立进程无法以可移植的方式解析它。
-
-发布是 fire-and-forget，失败只发出警告：注册表是一项可观测性辅助设施，因此注册表故障绝不能让正常工作的 agent（智能体）会话失败。会话在其注册仍在途中时结束，会留下一个 tombstone，让即将完成的注册观测到，因此它的记录不会一直存活到某次基于 pid 的清理才消失。
-
-## 配置
-
-无。每条发布的记录都从会话本身派生而来，因此没有留下任何逐部署的选择需要配置。
-
-## 模型体验
-
-无。该包（package）不注册工具、不注入提示词，也不追加会话事件；它只把既有的生命周期事件和标题事件镜像进宿主侧的进程记录。
-
-#### KV 缓存影响
-
-与实时请求相互独立：该插件读取会话事件，并写入一个独立的注册表文件，不触碰任何请求前缀，因此它无法使提供方 cache 复用失效。
-
-## 已知限制与延期工作
-
-- **被跳过的会话是不可见，而非延后处理**——创建时不带 `cwd` 的会话永不发布，即使之后工作区变为已知也不会；没有重新检查机制。
-- **标题镜像每次修订都要付出一次注册表写入**——每个 `session/title` 事件都会触发一次加锁的读取、修改和写入，因此改名节奏激进的部署要按修订次数付出这些写入。

-Live-session registry seam (`ctx.sessionRegistry`): the contract and record vocabulary for a cross-process registry of the sessions running right now, so a separate short-lived process such as `dsh list-sessions` can answer "what am I running". This package owns no medium — a backend (the lock-guarded JSON file in [`session-registry-file`](../session-registry-file/README.md) today, a database later) implements the abstract service.
-
-## Shape
-
-- `register(registration)` — publish `{ sessionId, cwd, title? }` stamped with this process's pid, a per-incarnation `bootId`, and `startedAt`. Replaces any existing record for the same session id. Returns the `ctx.effect` disposer; awaiting it waits for the removal to reach durability.
-- `retitle(sessionId, title)` — replace the recorded title of a session **this** process registered. Titles arrive after registration and can be revised, so it is the one mutable field. A record owned by another pid or incarnation is left alone, and an unknown id is a no-op because a title can resolve after the record is gone.
-- `list()` — every live record, newest registration last. Liveness is part of the contract, not the backend's discretion: every returned record's process existed at observation time, so a process killed without running its disposer leaves no permanent phantom.
-
-Backends serialize mutations against concurrent registrars — other processes and overlapping calls in this one — so records are never lost to a torn read-modify-write.
-
-## Record vocabulary
-
-`SessionRegistryRecord` carries `sessionId` (unique across live records), `pid`, `cwd`, `startedAt`, a `bootId` distinguishing a recycled pid from the original incarnation, and an optional `title`. The title travels in the record rather than being read from the session log because log location, format, and compression are per-deployment backend choices an independent reader cannot portably parse.
-
-## Model Experience
-
-None, as this package registers no tools, injects no prompts, and appends no session events; it defines the host-side listing contract only.
-
-#### KV Cache effect
-
-Independent of live requests: the registry never touches a request prefix, so nothing here can invalidate provider cache reuse.
-
-## Known Limitations and Deferred Work
-
-- **Records are process-scoped, not agent-scoped** — only top-level launcher surfaces publish. In-process subagents have no process of their own, and out-of-process subagent backends spawn `dsh-jsonrpc-agent` rather than the CLI, so neither appears in a listing.
-- **Liveness is pid existence, not health** — a hung or stopped process still lists as running; the contract deliberately makes no judgement about whether a session is making progress.

-
-存活会话注册表 seam（`ctx.sessionRegistry`）：定义跨进程「当前正在运行哪些会话」注册表的契约与记录词汇，使 `dsh list-sessions` 这类独立的短生命周期进程能够回答「我正在运行什么」。本包不拥有任何介质——由后端实现该抽象服务（今天是 [`session-registry-file`](../session-registry-file/README.md) 中加锁保护的 JSON 文件，将来可以是数据库）。
-
-## 形状
-
-- `register(registration)`：发布 `{ sessionId, cwd, title? }`，并盖上本进程的 pid、每个 incarnation 独有的 `bootId` 和 `startedAt`。同一会话 id 的既有记录会被替换。返回 `ctx.effect` disposer；await 它即等待移除达到持久性。
-- `retitle(sessionId, title)`：替换**本**进程注册的某个会话的已记录标题。标题在注册之后才到达，并且可以修订，因此它是唯一的可变字段。归属于其他 pid 或其他 incarnation 的记录不受影响；未知 id 为空操作，因为标题可能在记录消失之后才解析出来。
-- `list()`：返回全部存活记录，按注册时间从旧到新排列。存活性属于契约本身，而非后端的自由裁量：每条返回记录的进程在观察时刻都存在，因此未运行 disposer 就被杀掉的进程不会留下永久的幽灵记录。
-
-后端必须将变更与并发注册方（其他进程，以及本进程内相互重叠的调用）串行化，使记录不会因撕裂的读改写而丢失。
-
-## 记录词汇
-
-`SessionRegistryRecord` 携带 `sessionId`（在存活记录中唯一）、`pid`、`cwd`、`startedAt`、用于区分被复用 pid 与原 incarnation 的 `bootId`，以及可选的 `title`。标题随记录传递而非从会话日志读取，因为日志的位置、格式与压缩是各部署后端的选择，独立读取方无法可移植地解析。
-
-## 模型体验
-
-无。本包不注册工具、不注入提示词、不追加会话事件；它只定义宿主侧的列表契约。
-
-#### KV 缓存影响
-
-与在途请求无关：注册表从不触碰请求前缀，因此这里不会使提供方缓存复用失效。
-
-## 已知限制与后续工作
-
-- **记录以进程为粒度，而非以 agent 为粒度**——只有用户直接启动的顶层界面会发布。进程内 subagent 没有自己的进程，进程外 subagent 后端启动的是 `dsh-jsonrpc-agent` 而非本 CLI，两者都不会出现在列表中。
-- **存活性只表示 pid 存在，不表示健康**——挂起或停止的进程仍会被列为运行中；契约刻意不判断会话是否在推进。

 The TUI surface:
 
-- boots the shipped default config (`apps/cli/base.cordis.yml`), or the tree named by `--config <path>` (the demo/test escape for booting an alternate example tree), through [`dsh-app-boot`](../../packages/ui/app-boot/README.md);
+- boots `base.cordis.yml` plus `tui.cordis.yml` through [`dsh-app-boot`](../../packages/ui/app-boot/README.md); `--config <path>` applies a patch-list overlay instead of the personal overlay, while `--config-replace <path>` boots that file as the complete tree;
 - resumes a persisted session with `dsh --resume <session-id>` and, when the Node host exposes `process.execve`, supplies the TUI's in-place handoff host: after selector preflight and current-session flush, the host disposes the app and replaces the process with a normalized resume invocation; runtimes without process replacement leave the session running and say so. This CLI owns session identity and the exit line rather than the config: it mints or selects the `main` session id and provides it, plus the exact command that reproduces this invocation, on the boot context ([`MAIN_SESSION_ID_KEY`](../../packages/ui/tui/README.md) and `TUI_GOODBYE_MESSAGE_KEY`). No `cordis.yml` key can drop resume, and a missing or unreadable id fails loud instead of creating a fresh session;
 - treats the **invoking directory** as the workspace — sessions, relative paths, and workspace instructions resolve from the cwd (`dsh meta` is the sole exception, below);
 - tells the agent where its own source lives: after boot it adds a prompt section naming this harness checkout, resolved from the launcher's real path so it holds under a PATH symlink and an arbitrary cwd, so the self-referential `cordis` toolset can read and modify it;
 - applies the personal overlay from `~/.dsh` (see [app-boot's Personal config](../../packages/ui/app-boot/README.md#personal-config)): `.env` fills environment gaps (ambient > project `.env` > personal `.env`), `config.yaml` patches the booted tree.
 
-`dsh meta` is that same TUI with this harness checkout as the workspace, so working on dsh itself needs no `cd`. It chdirs to the checkout root — resolved from the launcher's real path, the same root the source-path prompt section names — after both `.env` layers are loaded, so environment precedence is unchanged while the session cwd, the `./.sessions` persistence root, and the HMR watch root all move together. It accepts only `--resume <id>`; `--config` (which would boot a foreign tree) and `-p` (which is not interactive) fail loud. Because meta sessions live under the checkout, `--resume` here sees only other meta sessions, and both the in-place handoff and the printed exit line reproduce the mode as `dsh meta --resume <id>`, so a copied command resumes the right session from any directory.
+`dsh meta` is that same TUI with this harness checkout as the workspace, so working on dsh itself needs no `cd`. It chdirs to the checkout root — resolved from the launcher's real path, the same root the source-path prompt section names — after both `.env` layers are loaded, so environment precedence is unchanged while the session cwd and HMR watch root move together. Meta always starts a fresh session and accepts no default-surface options; use ordinary `dsh --resume <id>` to resume a persisted session.
 
 `dsh migrate` and `dsh upgrade` are guided fresh-session entries over the default TUI surface: each mints a fresh session in the invoking directory and seeds its first turn with a bundled skill (`dsh-migrate` for migrating from another coding agent — opencode, pi, Claude Code, Codex; `dsh-upgrade` for upgrading this checkout), exactly as if the user typed `/skill:<name>`. 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 <id>` of the session is an ordinary TUI session with no re-injection.
 
 
-The Web and headless surfaces boot one shared composition (`cordis.yml`): both treat the invoking directory as the default project and Workspace root, create named Workspaces beneath that root unless `--workspace-root <path>` overrides it, load applicable `AGENTS.md`/`CLAUDE.md` instructions into each agent-loop request prefix with a 65,536-byte render budget, and opt into first-message model titles. 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 Web and headless surfaces boot `base.cordis.yml` plus `web.cordis.yml`; `dsh web --config <path>` adds an overlay after the web surface defaults. 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 <path>` overrides it, load applicable `AGENTS.md`/`CLAUDE.md` instructions into each agent-loop request prefix with a 65,536-byte render budget, and opt into first-message model titles. 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.

 - 使用 `dsh --resume <session-id>` 恢复已持久化会话。当 Node 宿主公开 `process.execve` 时，还会提供 TUI 的原地移交宿主：选择器预检并刷新当前会话后，宿主会释放应用，并以规范化的恢复调用替换进程；不支持进程替换的运行时会让会话继续运行并给出提示。会话身份与退出行由本 CLI 拥有，而非由配置指定：它创建或选定 `main` 会话 id，并把该 id 以及可复现本次调用的确切命令一起提供到启动上下文（[`MAIN_SESSION_ID_KEY`](../../packages/ui/tui/README.md) 与 `TUI_GOODBYE_MESSAGE_KEY`）。任何 `cordis.yml` 键都无法移除恢复能力；缺失或无法读取的 id 会明确报错，而不会创建新会话；
 - 将 **调用目录** 视为 workspace：会话、相对路径和 workspace 指令都从 cwd 解析（`dsh meta` 是唯一例外，见下文）；
 - 告知 agent 自身源码所在位置：启动后添加一个命名此 harness checkout 的提示词段。该路径从启动器的真实路径解析，因此在 PATH 符号链接和任意 cwd 下仍然有效，使自指的 `cordis` 工具集可以读取并修改它；
 - 应用 `~/.dsh` 中的个人覆盖（参见 [app-boot 的个人配置](../../packages/ui/app-boot/README.md#personal-config)）：`.env` 填补环境缺口（环境中已有的值 > 项目 `.env` > 个人 `.env`），`config.yaml` 则修补已启动的树。
 
-`dsh meta` 是以本 harness checkout 为 workspace 的同一个 TUI，因此开发 dsh 自身无需 `cd`。它在两层 `.env` 都加载之后才 chdir 到 checkout 根目录（从启动器的真实路径解析，与源码路径提示词段所指的根目录相同），因此环境优先级不变，而会话 cwd、`./.sessions` 持久化根目录与 HMR 监视根目录会一并移动。它只接受 `--resume <id>`；`--config`（会启动其他配置树）和 `-p`（非交互）都会明确报错。由于 meta 会话位于该 checkout 之下，此处的 `--resume` 只能看到其他 meta 会话；原地移交与打印的退出行都会以 `dsh meta --resume <id>` 复现该 mode，因此复制的命令在任何目录下都能恢复到正确的会话。

 `dsh migrate` 与 `dsh upgrade` 是默认 TUI 界面之上的引导式全新会话入口：各自在调用目录中创建一个全新会话，并以一个内置 skill 播种其首轮（`dsh-migrate` 用于从其他编码 agent 迁移——opencode、pi、Claude Code、Codex；`dsh-upgrade` 用于升级本 checkout），效果等同于用户手动键入 `/skill:<name>`。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 <id>` 恢复该会话时是普通 TUI 会话，不会重复注入。
 
 
-Web 和无头界面启动同一个共享组合（`cordis.yml`）：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 <path>` 覆盖，否则会在该根目录下创建具名 Workspace；它们会把适用的 `AGENTS.md`/`CLAUDE.md` 指令加载到每个 agent-loop 请求前缀中，渲染预算为 65,536 字节，并选用首条消息模型标题。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`）。

CI covers 22.19, 24, and 26; see the [Node engine floor Agent Note](../.agents/notes/implemented/process/2026-07-06-node-engine-floor.md).\n- Corepack-enabled pnpm. The repo pins `pnpm@11.7.0` in `package.json`; run `corepack enable` if `pnpm --version` does not resolve through Corepack.\n- Git 2.26 or newer; hook setup enables Git's worktree-specific configuration extension.\n- Optional: a DeepSeek API key for the TUI, headless, and ACP automation demos and real-API e2e tests.\n\n## First-time setup\n\nInstall dependencies from the repo root:\n\n```sh\npnpm install\n```\n\nThe install also runs the root `postinstall` script, which installs lefthook from the repo dev dependency through `scripts/install-lefthook.mjs`. With `CI=true` or `GITHUB_ACTIONS=true`, the wrapper returns before Git discovery because automated jobs do not consume contributor hooks. Otherwise, it requires Git 2.26 or newer and gives the current worktree an explicit hook directory under its own Git directory; linked worktrees therefore use their own lefthook binary and configuration instead of rewriting common hooks. The first install enables Git's worktree-specific configuration extension and repository format 1; see the [worktree-local hooks Agent Note](../.agents/notes/implemented/process/2026-07-27-worktree-local-lefthook.md).\n\nIf hooks are missing because dependencies were restored from cache or `postinstall` was skipped, install them manually:\n\n```sh\nnode scripts/install-lefthook.mjs\n```\n\nThe wrapper refuses user-owned `core.hooksPath` values. An inherited system, global, or common-repository path requires `DSH_LEFTHOOK_ALLOW_HOOKS_PATH_OVERRIDE=1`; command-scoped and worktree-scoped custom paths must be integrated or removed explicitly.\n\nBefore enabling worktree config, migrate direct `extensions.*` in a format-0 common config, direct `core.worktree` or `core.bare=true`, and any non-empty dormant `config.worktree`. The common config and every worktree config must be regular files, while the owned hook directory may contain only unaliased regular files.\n\nAfter moving a checkout, rerun the wrapper to relocate its owned path and regenerate hooks. For a stale or invalid installer lock, first confirm no installer is running, then remove the reported lock and retry. If installation and hook-path rollback both fail, inspect the reported worktree config before retrying. The [worktree-local hooks Agent Note](../.agents/notes/implemented/process/2026-07-27-worktree-local-lefthook.md) owns the full safety contract.\n\nRun typecheck once after a fresh clone:\n\n```sh\npnpm run typecheck\n```\n\nThat first typecheck runs the whole-repo `tsc -b` graph: it emits every package/vendor `lib/types` and checks examples, tests, and scripts through the two no-emit aggregates described below.\n\n## TypeScript project layout\n\nThe repository's TypeScript configuration has exactly three roles; every tsconfig file plays one of them.\n\n| File | Role | Forms a program? |\n|---|---|---|\n| `tsconfig.json` | Solution root: `extends` base, `files: []`, references to the two aggregates. The whole-repo `tsc -b tsconfig.json` graph, the tsserver discovery entry, and — through the inherited `paths` — the resolution config for tsx running `examples/` and `scripts/` (their nearest tsconfig is this file). | No |\n| `tsconfig.host.json` | Host aggregate: host-side packages (via references), examples, tests, scripts, website. Excludes `packages/client`. | Yes |\n| `tsconfig.client.json` | Client aggregate: `packages/client/*` packages and their tests, `apps/web`. | Yes |\n| `tsconfig.base.json` | Shared compilerOptions and the source `paths` map. Also the resolution facade the vitest configs point vite-tsconfig-paths at: it has no `include`, so its `paths` apply to every importer. | No |\n| `tsconfig.base.client.json` | Browser compiler shape (`jsx`, DOM libs, `types: []`) extended by the client aggregate and every `packages/client/*` package. | No |\n\nHost and client stay two aggregate programs because both sides declaration-merge the cordis `Context` interface under the same keys with different services; one program seeing both merges reports a collision. The collision exists only inside a `ts.Program` — module resolution never triggers it — which is why the solution may reference both aggregates and one paths facade may span both sides. Two disciplines follow:\n\n- `tsconfig.base.json` never gains `include` or `files`: they would leak into every extending package project and narrow the facade's match-all scope.\n- A script that builds a repo-wide `ts.Program` seeds `tsconfig.host.json` or `tsconfig.client.json` explicitly — never the root solution, because flattening both aggregates into one program collides the `Context` merges. Program-backed generators and gates (`scripts/ts-project.ts` consumers, doc-typecheck standalone mode) are host-only by decision; the client side gains program-backed tooling only with a concrete need.\n\nStatic analysis and tests resolve workspace imports through the base `paths` map to `src` and must pass on a clean tree; gates that consume built `lib/` output declare that dependency explicitly. Decision record: [solution-root note](../.agents/notes/implemented/process/2026-07-22-tsconfig-solution-root-two-aggregates.md); the tsc-first emit pipeline is the [ts-build-config note](../.agents/notes/implemented/process/2026-06-17-ts-build-config.md).\n\nIf a relevant local check consumes built package output, build once first:\n\n```sh\npnpm run build\n```\n\n`pnpm run hygiene` includes `publint`, which validates package entrypoints against the built `lib/*.js` files, and `verify-node-next-types`, which validates built declarations against a temporary NodeNext consumer. A fresh worktree has no bundled JS or declarations until `pnpm run build` runs; ordinary commits and pushes do not require that build unless their selected checks consume it.\n\n## Environment variables\n\nThe real DeepSeek adapter and key-backed agent demos read credentials from the environment or from a gitignored `.env` at the repo root:\n\n```sh\nDEEPSEEK_API_KEY=sk-...\nDEEPSEEK_BASE_URL=https://... # optional\n```\n\n`DEEPSEEK_BASE_URL` is optional and defaults to the public API. Never commit real credentials. The real-API e2e suites self-skip when `DEEPSEEK_API_KEY` is not set.\n\n## Git hooks\n\nlefthook is configured in `lefthook.yml` as a fast local checkpoint:\n\n- `pre-commit` runs staged-file ESLint fixes, checks the staged diff for whitespace errors, and runs the vendor manifest guard.\n- `pre-push` runs only the incremental repository typecheck (`tsc -b` over the root solution, covering both the host and client aggregates).\n\nThe vendor manifest guard checks that changes under `vendor/*/src` are staged with the matching `vendor/README.md` manifest update. See `vendor/README.md` before editing vendored code.\n\nThe hooks intentionally do not run tests, snapshots, documentation checks, builds, or hygiene. Contributors run the [checks relevant to the changed behavior](../AGENTS.md#run-relevant-checks-locally) once; CI owns exhaustive coverage, built-artifact smokes, and the Node 22.19, 24, and 26 compatibility matrix.\n\nContributors can opt into the comprehensive local gate set with `pnpm run check:all`. The command is independent of both Git hooks and is not an agent instruction.\n\n## CI gates\n\nThe keyless [CI workflow](../.github/workflows/ci.yml) groups independent gates into broad lanes and runs a smaller compatibility signal across supported Node versions. Artifact consumers wait for one build within their lane. The separate real-API workflow runs `pnpm run test:e2e` with its configured worker bound. See [scripts/run-gates.ts](../scripts/run-gates.ts) and the workflow files for the current gate and job inventory.\n\n## Daily commands\n\nUse these from the repo root:\n\n```sh\npnpm run test           # unit tests\npnpm run test:coverage  # unit tests with per-file coverage gates\npnpm run test:e2e       # real-API tests; self-skips without DEEPSEEK_API_KEY\npnpm run check:all      # comprehensive opt-in gate set; not wired to Git hooks\npnpm run typecheck      # tsc -b over the root solution: emits package/vendor lib/types, checks both aggregates\npnpm run lint           # eslint .\npnpm run lint:fix       # eslint . --fix\npnpm run doc-typecheck  # compile checked TypeScript snippets in Markdown docs\npnpm run gen-cordis-catalog     # regenerate docs/cordis-catalog/events.md + services.md from source\npnpm run verify-cordis-catalog  # fail if either cordis catalog is stale\npnpm run verify-export-jsdoc    # fail if a module-level package export lacks complete JSDoc\npnpm run gen-doc-graphs     # regenerate generated relationship docs from source and curated graph definitions\npnpm run verify-doc-graphs  # fail if generated relationship docs are stale\npnpm run verify-md-wrap  # fail on hard-wrapped prose paragraphs in docs/README markdown\npnpm run verify-mermaid  # fail if a ```mermaid diagram has invalid Mermaid syntax\npnpm run verify-type-equiv  # fail if a ```ts type-equiv doc block drifts from its source type\npnpm run verify-doc-budgets  # fail if a budgeted standing doc exceeds its word ceiling\npnpm run gen-translation-brief   # print the minimal-update briefing for out-of-sync translation pairs (--apply splices code-only edits)\npnpm run doc-sync       # all Markdown/doc gates, scheduled concurrently; the doc-sync leaf list in scripts/run-gates.ts is the full list\npnpm run gen-module-graph     # regenerate docs/module-graph.md from package peerDeps\npnpm run verify-module-graph  # fail if docs/module-graph.md is stale\npnpm run build          # emit lib/types intermediates, then bundle lib/index.* runtime files\npnpm run verify-node-next-types  # fail if built declarations are not NodeNext-consumable\npnpm run hygiene        # knip, publint, workspace constraints, and NodeNext declaration check\n```\n\nWhen changing package public behavior, update the relevant README or JSDoc in the same change. `pnpm run doc-sync` catches checked TypeScript snippets, generated doc freshness, markdown wrap/link drift, type equivalence, translation pairing, Mermaid syntax, and doc budgets, but broader prose/API sync still needs review.\n\n## Demos\n\nThe one-shot Headless coding agent needs `DEEPSEEK_API_KEY` in the environment or repo-root `.env`:\n\n```sh\npnpm run demo:headless \"summarize this workspace\"\n```\n\nThe full-screen interactive coding agent needs `DEEPSEEK_API_KEY` in the environment or repo-root `.env`:\n\n```sh\npnpm run demo:tui\n```\n\nThe self-referential cordis demo can inspect and modify its live plugin runtime and needs the same credentials (`web` by default, or `acp`):\n\n```sh\npnpm run demo:cordis\n```\n\nThe ACP automation server exposes fresh agent sessions over JSON-RPC stdio and also needs `DEEPSEEK_API_KEY`:\n\n```sh\npnpm run demo:acp\n```\n\n## TODO markers\n\nUse one of three comment tags to flag known issues in the code, ordered by urgency:\n\n- `FIXME` — an issue that should block a new release. A release should not ship with an open `FIXME` unless reviewers explicitly agree the change can be merged anyway.\n- `TODO` — an issue that should be fixed soon, once we have the resources.\n- `XXX` — an issue that we may fix someday; lowest priority, no commitment.\n\nPick the tag that matches the urgency so anyone scanning the code can tell a release blocker from a someday-maybe.\n\n## Documenting types verbatim (`ts type-equiv`)\n\nThe [core data structures](core-data-structures/core.md) docs paste source-equivalent declarations together with their original JSDoc so a reader sees the exact shape and source contract. To keep a paste from drifting when source changes, fence it as ` ```ts type-equiv ` (instead of ` ```ts `) and register it in `scripts/type-equiv.manifest.json` with the source file and symbol it mirrors:\n\n```json\n{ \"doc\": \"docs/core-data-structures/session.md\", \"symbol\": \"SessionEvent\", \"source\": \"packages/core/session/src/types.ts\" }\n```\n\n`pnpm run verify-type-equiv` (part of `doc-sync`) then extracts that symbol's declaration and attached JSDoc from source via the TypeScript parser and asserts the block matches both. For a class whose implementation bodies do not belong in the catalog, use ` ```ts public-api ` and set `\"projection\": \"public-api\"`; the checked projection retains the public fields, constructor, accessors, methods, and original class/member JSDoc while omitting bodies and private or protected members. Comparison ignores whitespace and non-JSDoc comments but requires every original JSDoc comment, including member documentation, so readers see the source contract beside the exact shape. The gate enforces a 1:1 correspondence by document, symbol, and projection between primary blocks and manifest entries; a paired `.zh.md` block reuses its unsuffixed sibling's entry only when the whole tracked fence sequence is byte-identical and ordered identically. `doc-typecheck` applies the same derivative rule to compilable fences, while skipping both source-equivalence fence kinds from compilation and its opt-out ratio. When you change a documented declaration or its JSDoc, the gate fails until you update the paste; when you add or remove a primary block, update the manifest in the same change.\n\n## Architecture context\n\nRead `docs/architecture.md` before changing anything under `packages/`. The codebase is built around Cordis plugins, event-sourced sessions, typed service seams, and explicit extension points.\n"
+        "content": "# Development guide\n\nEnglish | [中文](development.zh.md)\n\nThis onboarding guide helps project contributors get started with the local environment, daily workflow, and CI flow; see the Agent Notes for design rationale and technical trade-offs.\n\n## Prerequisites\n\n- Node.js supports 22.19+ and 24+. CI covers 22.19, 24, and 26; see the [Node engine floor Agent Note](../.agents/notes/implemented/process/2026-07-06-node-engine-floor.md).\n- Corepack-enabled pnpm. The repo pins `pnpm@11.7.0` in `package.json`; run `corepack enable` if `pnpm --version` does not resolve through Corepack.\n- Git 2.26 or newer; hook setup enables Git's worktree-specific configuration extension.\n- Optional: a DeepSeek API key for the TUI, headless, and ACP automation demos and real-API e2e tests.\n\n## First-time setup\n\nInstall dependencies from the repo root:\n\n```sh\npnpm install\n```\n\nThe install also runs the root `postinstall` script, which installs lefthook from the repo dev dependency through `scripts/install-lefthook.mjs`. With `CI=true` or `GITHUB_ACTIONS=true`, the wrapper returns before Git discovery because automated jobs do not consume contributor hooks. Otherwise, it requires Git 2.26 or newer and gives the current worktree an explicit hook directory under its own Git directory; linked worktrees therefore use their own lefthook binary and configuration instead of rewriting common hooks. The first install enables Git's worktree-specific configuration extension and repository format 1; see the [worktree-local hooks Agent Note](../.agents/notes/implemented/process/2026-07-27-worktree-local-lefthook.md).\n\nIf hooks are missing because dependencies were restored from cache or `postinstall` was skipped, install them manually:\n\n```sh\nnode scripts/install-lefthook.mjs\n```\n\nThe wrapper refuses user-owned `core.hooksPath` values. An inherited system, global, or common-repository path requires `DSH_LEFTHOOK_ALLOW_HOOKS_PATH_OVERRIDE=1`. When Git seeds a new worktree with another registered worktree's marker-backed hook path, the wrapper replaces that copied value with the new worktree's own path; command-scoped and other worktree-scoped paths must be integrated or removed explicitly.\n\nBefore enabling worktree config, migrate direct `extensions.*` in a format-0 common config, direct `core.worktree` or `core.bare=true`, and any non-empty dormant `config.worktree`. The common config and every worktree config must be regular files, while the owned hook directory may contain only unaliased regular files.\n\nAfter moving a checkout, rerun the wrapper to relocate its owned path and regenerate hooks. For a stale or invalid installer lock, first confirm no installer is running, then remove the reported lock and retry. If installation and hook-path rollback both fail, inspect the reported worktree config before retrying. The [worktree-local hooks Agent Note](../.agents/notes/implemented/process/2026-07-27-worktree-local-lefthook.md) owns the full safety contract.\n\nRun typecheck once after a fresh clone:\n\n```sh\npnpm run typecheck\n```\n\nThat first typecheck runs the whole-repo `tsc -b` graph: it emits every package/vendor `lib/types` and checks examples, tests, and scripts through the two no-emit aggregates described below.\n\n## TypeScript project layout\n\nThe repository's TypeScript configuration has exactly three roles; every tsconfig file plays one of them.\n\n| File | Role | Forms a program? |\n|---|---|---|\n| `tsconfig.json` | Solution root: `extends` base, `files: []`, references to the two aggregates. The whole-repo `tsc -b tsconfig.json` graph, the tsserver discovery entry, and — through the inherited `paths` — the resolution config for tsx running `examples/` and `scripts/` (their nearest tsconfig is this file). | No |\n| `tsconfig.host.json` | Host aggregate: host-side packages (via references), examples, tests, scripts, website. Excludes `packages/client`. | Yes |\n| `tsconfig.client.json` | Client aggregate: `packages/client/*` packages and their tests, `apps/web`. | Yes |\n| `tsconfig.base.json` | Shared compilerOptions and the source `paths` map. Also the resolution facade the vitest configs point vite-tsconfig-paths at: it has no `include`, so its `paths` apply to every importer. | No |\n| `tsconfig.base.client.json` | Browser compiler shape (`jsx`, DOM libs, `types: []`) extended by the client aggregate and every `packages/client/*` package. | No |\n\nHost and client stay two aggregate programs because both sides declaration-merge the cordis `Context` interface under the same keys with different services; one program seeing both merges reports a collision. The collision exists only inside a `ts.Program` — module resolution never triggers it — which is why the solution may reference both aggregates and one paths facade may span both sides. Two disciplines follow:\n\n- `tsconfig.base.json` never gains `include` or `files`: they would leak into every extending package project and narrow the facade's match-all scope.\n- A script that builds a repo-wide `ts.Program` seeds `tsconfig.host.json` or `tsconfig.client.json` explicitly — never the root solution, because flattening both aggregates into one program collides the `Context` merges. Program-backed generators and gates (`scripts/ts-project.ts` consumers, doc-typecheck standalone mode) are host-only by decision; the client side gains program-backed tooling only with a concrete need.\n\nStatic analysis and tests resolve workspace imports through the base `paths` map to `src` and must pass on a clean tree; gates that consume built `lib/` output declare that dependency explicitly.

self-skips without DEEPSEEK_API_KEY\npnpm run check:all      # comprehensive opt-in gate set; not wired to Git hooks\npnpm run typecheck      # tsc -b over the root solution: emits package/vendor lib/types, checks both aggregates\npnpm run lint           # eslint .\npnpm run lint:fix       # eslint . --fix\npnpm run doc-typecheck  # compile checked TypeScript snippets in Markdown docs\npnpm run gen-cordis-catalog     # regenerate docs/cordis-catalog/events.md + services.md from source\npnpm run verify-cordis-catalog  # fail if either cordis catalog is stale\npnpm run verify-export-jsdoc    # fail if a module-level package export lacks complete JSDoc\npnpm run gen-doc-graphs     # regenerate generated relationship docs from source and curated graph definitions\npnpm run verify-doc-graphs  # fail if generated relationship docs are stale\npnpm run verify-md-wrap  # fail on hard-wrapped prose paragraphs in docs/README markdown\npnpm run verify-mermaid  # fail if a ```mermaid diagram has invalid Mermaid syntax\npnpm run verify-type-equiv  # fail if a ```ts type-equiv doc block drifts from its source type\npnpm run verify-doc-budgets  # fail if a budgeted standing doc exceeds its word ceiling\npnpm run gen-translation-brief   # print the minimal-update briefing for out-of-sync translation pairs (--apply splices code-only edits)\npnpm run doc-sync       # all Markdown/doc gates, scheduled concurrently; the doc-sync leaf list in scripts/run-gates.ts is the full list\npnpm run gen-module-graph     # regenerate docs/module-graph.md from package peerDeps\npnpm run verify-module-graph  # fail if docs/module-graph.md is stale\npnpm run build          # emit lib/types intermediates, then bundle lib/index.* runtime files\npnpm run verify-node-next-types  # fail if built declarations are not NodeNext-consumable\npnpm run hygiene        # knip, publint, workspace constraints, and NodeNext declaration check\n```\n\n修改 package 的公开行为时，请在同一个变更中更新相关 README 或 JSDoc。`pnpm run doc-sync` 能检测到被检查的 TypeScript 片段、生成文档的新鲜度、Markdown 换行/链接漂移、type-equiv、翻译配对、Mermaid 语法和文档预算，但更广泛的行文/API 同步仍需评审把关。\n\n## 演示\n\n单次运行的 Headless coding agent 需要环境变量或仓库根目录 `.env` 中的 `DEEPSEEK_API_KEY`：\n\n```sh\npnpm run demo:headless \"summarize this workspace\"\n```\n\n全屏交互式 coding agent 需要环境变量或仓库根目录 `.env` 中的 `DEEPSEEK_API_KEY`：\n\n```sh\npnpm run demo:tui\n```\n\n自指的 cordis 演示可以检查并修改其实时插件运行时，并需要相同的凭证（默认 `web`，也可用 `acp`）：\n\n```sh\npnpm run demo:cordis\n```\n\nACP 自动化服务器通过 JSON-RPC stdio 提供全新 agent 会话，同样需要 `DEEPSEEK_API_KEY`：\n\n```sh\npnpm run demo:acp\n```\n\n## TODO 标记\n\n请使用以下三种注释标签之一标记代码中的已知问题，按紧急程度排序：\n\n- `FIXME`：应当阻塞新版本发布的问题。除非评审者明确同意该更改可以合并，否则发布版本不应包含未解决的 `FIXME`；\n- `TODO`：应当尽快修复的问题，等资源到位即可处理；\n- `XXX`：也许某天会修复的问题，优先级最低，不作承诺。\n\n请选择与紧急程度匹配的标签，让浏览代码的人一眼分清「发布阻塞」和「有空再说」。\n\n## 逐字记录类型（`ts type-equiv`）\n\n[核心数据结构](core-data-structures/core.md)文档会把与源码等价的声明及其原始 JSDoc 一并粘贴，让读者看到确切形状和源码契约。为防止粘贴内容在源码变化时漂移，请将其围栏为 ` ```ts type-equiv `（而不是 ` ```ts `），并在 `scripts/type-equiv.manifest.json` 中登记它镜像的源文件和符号：\n\n```json\n{ \"doc\": \"docs/core-data-structures/session.md\", \"symbol\": \"SessionEvent\", \"source\": \"packages/core/session/src/types.ts\" }\n```\n\n`pnpm run verify-type-equiv`（`doc-sync` 的一环）随后通过 TypeScript 解析器从源码提取该符号的声明及其附带的 JSDoc，并断言代码块同时匹配两者。对于不应把实现体写进目录的类，请使用 ` ```ts public-api ` 并设置 `\"projection\": \"public-api\"`；门禁检查的投影会保留公共字段、构造函数、访问器、方法以及类和成员的原始 JSDoc，同时省略实现体和私有或受保护成员。比对会忽略空白和非 JSDoc 注释，但要求保留每条原始 JSDoc（包括成员文档），让读者同时看到源码契约和确切形状。该门禁按文档、符号和投影，在主块与 manifest 条目之间强制 1:1 对应；只有当配对 `.zh.md` 块的完整受跟踪围栏序列与其无后缀兄弟文件按字节一致且顺序相同时，才会复用后者的条目。`doc-typecheck` 对可编译围栏应用同一派生规则，同时跳过两种源码等价围栏的编译，并将其排除在 opt-out 比例之外。当你改动一个已记录的类型声明或其 JSDoc 时，门禁会失败直到你更新粘贴内容；当你增删一个主块时，请在同一个变更里更新 manifest。\n\n## 架构上下文\n\n在修改 `packages/` 目录下的任何内容之前，请先阅读 `docs/architecture.md`。这套代码围绕 Cordis 插件、事件溯源的会话、类型化的服务 seam 与显式扩展点构建。\n"

-自指 harness 演示：在全屏 TUI 上运行 DeepSeek V4 编码主干，并加载 [`@deepseek-ai/dsh-tool-cordis`](../../packages/cordis/tool-cordis/README.md)。后者让模型检查当前 DSH 进程、挂载仅存于内存的临时插件，并卸载它们。临时插件可跨轮次保持活跃，但会在卸载、工具集卸载或 DSH 重启后消失；它们不创建文件或配置，也可能影响同一进程中的其他会话。`ctx.fs` 和 `ctx.web` 仅以能力提供方形式加载，供这些插件使用。设计详见[工具集 Agent Note（agent 决策记录）](../../.agents/notes/implemented/feature/2026-07-08-self-referential-cordis-toolset.md)。

-## 运行
-
-```sh
-# repo root .env (gitignored) or exported env:
-#   DEEPSEEK_API_KEY=sk-…
-#   DEEPSEEK_BASE_URL=https://…   # optional; defaults to the public API
-pnpm run demo:cordis      # TUI (default)
-pnpm run demo:cordis web  # browser UI at http://127.0.0.1:3081
-pnpm run demo:cordis acp  # ACP server
-```
-
-预期演示分阶段进行：先验证监听器链路，再让 agent（智能体）扩展自身：
-
-```
-> Mount a temporary Plugin that listens to the 'agent/status' event and logs every status change, then run `echo hi` with bash.
-  [tool call] cordis_mount({"code": "return { name: 'status-logger', apply(ctx) { ctx.on('agent/status', (agent, status) => console.log('status →', status)) } }"})
-  [tool result] Temporary Plugin dyn-1 is running (plugin "status-logger"; available until unmounted or DSH restarts).
-  [tool call] bash({"command": "echo hi"})
-[cordis:dyn-1] status → …            ← the temporary listener firing, live
-> Now give yourself a reverse_text tool and use it on "harness".
-  [tool call] cordis_mount({"code": "return { name: 'reverse-text', inject: ['tools'], apply(ctx) { ctx.tools.register(harness.defineTool({ name: 'reverse_text', … })) } }"})
-  [tool call] reverse_text({"text": "harness"})   ← a tool the agent built for itself, one step earlier
-> Unmount both temporary Plugins.
-  [tool call] cordis_unmount({"id": "dyn-1"})
-```
-
-请求 `cordis_inspect` 并使用 `what: "api"` 或 `what: "events"`，即可查看编写插件代码所用的生成服务／事件资料。还可挂载两个协作临时插件（一个中调用 `ctx.provide`，另一个中使用 `inject`），观察 Cordis 如何暂停并恢复消费方。
-
-## 端到端测试
-
-`tests/keyless-smoke.e2e.ts` 使用虚拟密钥通过 Loader 启动真实 `cordis.yml`，并断言横幅、包名解析，以及收到 EOF 后正常退出。`tests/cordis-tools.e2e.ts` 是带密钥的冒烟测试：真实模型挂载一个临时状态监听器，测试验证其带标记的控制台输出行；然后创建并使用 `reverse_text` 工具，再通过 provide/inject 组合两个临时插件。[`packages/cordis/tool-cordis`](../../packages/cordis/tool-cordis) 包含相关单元测试，并受逐文件 100% 覆盖率门禁约束。

-# tui-agent
-
-[English](README.md) | 中文
-
-全屏交互式编码 agent（智能体）：DeepSeek V4、本地 bash 与文件系统工具、压缩（compaction）、subagent、工作流与全新 agent Ralph 迭代、plan mode（`/plan` 进入，`exit_plan_mode` 评审退出）、超时／溢出策略，以及通过 [`@deepseek-ai/dsh-tui-demo`](../../packages/examples/tui-demo) 提供的 JSONL 持久化；该应用从 `cordis.yml` 加载。同级 [`headless-agent`](../headless-agent/README.md) 以适合管道调用的单次任务形式运行同一能力类，[`acp-agent`](../acp-agent/README.md) 则通过 JSON-RPC 提供该能力。
-
-## 运行
-
-```sh
-# repo root .env (gitignored) or exported env:
-#   DEEPSEEK_API_KEY=sk-…
-#   DEEPSEEK_BASE_URL=https://…   # optional; defaults to the public API
-pnpm run demo:tui
-```
-
-演示脚本和可安装的 `dsh` CLI（命令行界面，见 [`apps/cli`](../../apps/cli/README.md)）都会以此示例的 `cordis.yml` 作为已交付的默认配置启动；`dsh` 还会应用 `~/.dsh` 中的个人覆盖，并将调用目录作为工作区。
-
-输入一项编码任务。agent 使用 `read`/`write`/`edit` 文件系统工具处理常规文件操作，使用 `bash`（加上面向后台任务的通用 `task_output`/`task_list`/`task_kill`）执行 shell 命令、搜索和测试。每次 bash 调用都在新的 `bash -c` 中运行（系统提示词要求模型传递 `workdir`，而不是使用 `cd`）。文件系统工具和 bash 都会相对于会话工作区解析相对路径。agent 还可以通过 `subagent`/`subagent_fork` 委托。
-
-`todo_write` 任务跟踪器是选用的，不在已交付配置中：请将 `@deepseek-ai/dsh-tool-todo` 添加到 `cordis.yml`（或在 `~/.dsh` 下使用个人配置覆盖）以公开该工具。加载后，模型会把整表计划记录到会话日志，TUI 则渲染它。
-
-TUI 渲染 Markdown 历史、推理（reasoning）、工具自有的终端／diff／通用卡片、token 总量，以及加载 `todo_write` 时的最新计划。较长的工具正文保留首尾预览；Ctrl+O 展开或折叠所有卡片。Enter 用于提交，或在 agent 运行时进行 steering（中途引导）；Ctrl+R 切换推理，Escape 取消，`/help` 列出命令。`/plan` 为下一步骤选择 plan mode；`/plan <message>` 还会将消息提交到该步骤，`/plan off` 则在没有模型输入的情况下选择默认 mode。`/status` 会展开当前会话的标识、活动计数、精确 token／缓存 bucket、上下文用量和时间戳，而不中断正在运行的轮次。`/model` 打开当前提供方目录的键盘选择器；使用 Up/Down 聚焦模型，使用 Shift+Tab 循环切换为该模型公布的推理强度，再用 Enter 选择；也可以使用 `/model <model>` 和 `/model <provider>/<model>` 直接选择。`ask_user_question` 会打开一个位于左下方的宽键盘面板，包含批次进度和编号选项。
-
-### 恢复早先的会话
-
-每次运行默认都会启动新会话（其事件日志落在 `./.sessions/` 下）。如需 **继续** 先前对话，请将其 id 传给已安装的 `dsh` CLI：此时 `main` agent 会重新水化持久日志，而不会从头开始，因此模型会将早先轮次视为历史：
-
-```sh
-dsh --resume <prior-session-id>
-```
-
-`/resume` 打开可搜索键盘选择器，显示标题、活动、上一轮结果、模型路由、持久化目标阶段和实时／已持久化状态。已安装的 `dsh` 宿主会等待刷写完成，对当前应用执行 dispose（资源释放），然后以 `dsh --resume <id>` 替换进程。TUI 仍会在退出时打印该命令，并在自定义宿主无法移交时显示它。`dsh --resume <id>` 在启动上下文中提供 id，`cordis.yml` 会读取它（`resumeSessionId: !!js "typeof resumeSessionId === 'string' ? resumeSessionId : undefined"`）；没有标志时，agent 会开始新会话。缺失或无法读取的 id 不会启动 agent，而会发出 `agent-loop/config-start-failed`：TUI 打印失败并以非零状态退出。选择器没有跨进程会话锁，因此拥有并发宿主的部署必须自行协调会话所有权。
-
-## Code Mode
-
-[`code-mode.cordis.yml`](code-mode.cordis.yml) 在同一树上覆盖 worker 线程运行时和 `tools: { mode: code }`。模型会收到一个 `run_code` 传输工具，加上一份为可见工具生成的 TypeScript SDK；只有程序输出会返回模型上下文。使用 `mode: both` 可在 `run_code` 旁同时公开原生调用。执行契约详见 [Code Mode Agent Note（agent 决策记录）](../../.agents/notes/implemented/feature/2026-06-15-code-mode.md)。
-
-```sh
-pnpm run demo:code-mode        # this overlay under the TUI (default UI)
-pnpm run demo:code-mode acp    # the acp-agent example's same-shaped overlay
-```
-
-尝试一项横跨多个工具调用的任务，例如：
-
-> 统计 docs/ 下每个 `*.md` 文件的行数，并将最大的三个写入 summary.txt。
-
-然后观察 transcript（文本记录）：一次 `run_code` 调用、一个循环调用工具的程序，以及模型筛选后的结果，而不是五次原始工具输出往返。
-
-## 每个叶节点配置项所演示的内容
-
-此示例是轻量叶节点 `cordis.yml`：它选择可替换后端、加载一个应用包（package），并添加有意放在共享主干外的产品工具。主干（会话、系统提示词、工具、agent、不变式、`agent-loop`）和入口集群（JSONL 持久化、pi-tui 通道、预创建的 `main` agent）位于 [`@deepseek-ai/dsh-tui-demo`](../../packages/examples/tui-demo) 应用及其加载的 [`@deepseek-ai/dsh-agent-spine-demo`](../../packages/examples/agent-spine-demo) 组合包中；叶节点负责接线后端与面向模型的可选工具：
-
-| 配置项 | 演示内容 |
-|---|---|
-| `hmr` (`@cordisjs/plugin-hmr`) | 开发／演示的编辑-重载循环：它是 **叶节点** 配置项（不内置到应用），因为它依赖 Loader 的内部模块访问 |
-| `llm-deepseek` | 默认原生适配器 |
-| `bash` (`dsh-bash-local`) | 执行器实现：bash seam 中可替换的实现侧。面向模型的 `bash` schema（`tool-bash`）和通用 `task_*` 控制（`tool-tasks`）由 `dsh-agent-spine-demo` 提供，因此叶节点只选择执行器 |
-| `tui-agent` (`@deepseek-ai/dsh-tui-demo`) | 应用组合包：agent-spine 演示 + JSONL 持久化 + pi-tui 通道 + 预创建的 `main` agent |
-| `subagent`, `subagent-spawn`, `subagent-fork` | subagent 提供方注册表加两个进程内后端：新子 agent，以及用父 agent 已完成轮次前缀播种的子 agent |
-| `tool-subagent`, `tool-subagent-fork` | 两次面向模型的 `dsh-tool-subagent` 加载，每次绑定不同提供方，并以不同工具名（`subagent`、`subagent_fork`）公开 |
-| `workflow-workerthread`, `tool-workflow` | worker 线程工作流引擎及其面向模型的 `workflow` 工具，子调用通过 spawn 后端路由 |
-| `plan-mode` | 插件拥有的 `/plan [message]` 进入命令和 `/plan off` 退出命令、plan-mode 提示词策略、工具限制，以及经评审的 `exit_plan_mode` 转换 |
-| `fs-local`, `fs-policy`, `tool-fs` | 文件系统栈：本地 `ctx.fs` 提供方、先读后写／编辑策略门禁（位于 `fs/*` 事件门禁），以及面向模型的 `read`/`write`/`edit` 工具。相对路径相对于会话工作区解析 |
-
-## 端到端测试（`pnpm run test:e2e`）
-
-与 UI 无关的带密钥套件通过 `tests/harness.ts` 以程序方式组装完整栈（无 PTY、无 Loader）：
-
-- `tests/full-loop.e2e.ts`：canary 测试：真实模型通过真实 bash 工具运行 `echo e2e-ok`；断言 `tool/call`/`tool/result` 会话事件和最终答案。
-- `tests/coding-task.e2e.ts`：类 swebench 冒烟测试：临时目录包含 `add.js`（其中 `a - b` 写在本应是 `a + b` 的位置）和失败的 `add.test.js`；agent 必须修复错误并验证。测试会自行重新运行 `node add.test.js` 并检查文件，不信任 agent 的说法。
-- `tests/resume.e2e.ts`：跨进程持久连续性：第一次运行告诉真实模型一个密码并将轮次持久化到临时 JSONL 根目录，然后 dispose 整个上下文；第二次运行在同一根目录上创建新上下文，恢复会话 id 并要求模型回忆密码。只有重新水化的日志能够提供该回忆。
-- `tests/compaction.e2e.ts`：压缩冒烟测试：一项真实多步 bash 任务在故意设得很小的上下文窗口中运行，使自动压缩监听器在会话中途触发。测试验证外部状态：真实日志中出现 `compact/start…end` 对，模型可见内容缩减（一个替换节点遮蔽了较旧节点），且 agent 在压缩后仍给出正确最终答案。
-- `tests/todo-write.e2e.ts`：加载选用的 `todo_write` 工具，由真实模型驱动，测试验证产生的 `todo/write` 会话事件。
-- `tests/code-mode.e2e.ts`：带密钥 Code Mode 证明：使用真实模型和双工具任务，断言协议层工具列表精确为 `[run_code]`，`tool/code-dispatch` 事件位于父调用下，且筛选后的答案已返回。
-
-这些测试在没有 `DEEPSEEK_API_KEY` 时自行跳过。无密钥 `tests/tui-keyless-smoke.e2e.ts` 通过 PTY 启动真实 Loader 树（唯一获准的 PTY 界面）：基础启动 + `/plan` + `/exit`，一次带问题对话框和工具往返的脚本 LLM（大语言模型）对话，Code Mode 覆盖配置的欢迎行，以及恢复失败退出路径。
-

-`tests/snapshots/<scenario>/session.jsonl` 提供已录制的用户提示词和模型分片；同级子日志驱动 subagent 和工作流。无密钥套件通过真实循环和工具实现执行这些脚本，然后比较可读的预期终端单元格／样式输出。对于仅涉及展示的变更，使用 `pnpm run test:snapshot:refresh`；已录制的模型流程改变时，使用 DeepSeek 密钥运行 `pnpm run test:snapshot:record`。已实现的 [TUI 快照 Agent Note](../../.agents/notes/implemented/testing/2026-07-18-tui-terminal-state-snapshots.md) 规定了场景矩阵，以及已录制旅程、包级瞬态快照与 PTY 覆盖之间的分工。

-## 内置组件
-
-| 插件 | 设置在此处的原因 |
-|---|---|
-| `@deepseek-ai/dsh-agent-spine-demo` | 共享服务、面向模型的工具，以及一个已配置的 `main` agent |
-| `@deepseek-ai/dsh-commands` | 供 TUI 和命令插件消费、仅面向人类的命令发现与分发 |
-| `@deepseek-ai/dsh-command-goal` | 直接在主干的持久化目标栈上提供 `/goal` 状态与变更 |
-| `@deepseek-ai/dsh-session-persistence-jsonl` | 位于 `persistenceRoot` 下的持久会话日志 |
-| `@deepseek-ai/dsh-session-checkpoint-policy` | 模型请求和顶层工具 effect 前的语义持久性屏障，以及已完成步骤的检查点 |
-| `@deepseek-ai/dsh-session-query-sqlite` + `@deepseek-ai/dsh-session-reference` | TUI 消费的组合式精确／FTS 会话查询与有界 `@session` 快照；面向模型的查询工具仍由叶节点选用 |
-| `@deepseek-ai/dsh-user-interaction` | 与提供方无关的人类问题服务 |
-| `@deepseek-ai/dsh-tui` | 全屏 transcript（文本记录）、编辑器、工具卡片、计划与问题 overlay |
-| `@deepseek-ai/dsh-tool-ask-user` | 面向模型的 `ask_user_question` 工具 |
-
-可替换的 LLM（大语言模型）、bash、文件系统和其他能力提供方仍留在叶节点配置中。`@cordisjs/plugin-hmr` 也仍是仅叶节点使用的开发条目，因为它需要 Loader 内部实现。

-## 配置
-
-| 键 | 默认值 | 路由目标 |
-|---|---|---|
-| `provider` | 必填 | 已配置 `main` agent 的提供方 |
-| `model` | 必填 | 已配置 `main` agent 的模型 |
-| `maxParallelToolCalls` | agent-loop 默认值 | 组合包内循环的并发上限 |
-| `persona` | 无 | 系统提示词 persona 模板 |
-| `toolOrder` | 字典序 | 显式的面向模型工具顺序 |
-| `tools` | 拥有者默认值 | 工具呈现模式 |
-| `dshHome` | 拥有者默认值 | bash 与 skill（技能）使用的 harness 主目录 |
-| `sessionTitle` | 主干示例限制 | 后备标题词数／字节限制 |
-| `skills` | 拥有者默认值 | skill 注册表、本地提供方和工具配置 |
-| `toolBash` | 拥有者默认值 | 面向模型的 bash 工具配置 |
-| `toolTasks` | 拥有者默认值 | 后台任务控制工具配置，或 `false` |
-| `goals` | 拥有者默认值 | 持久目标领域与模型工具配置；`false` 会移除目标栈与 `/goal` 生产方 |
-| `workspaceContext` | 必填 | Workspace 指令配置，或 `false` |
-| `persistenceRoot` | `./.sessions` | JSONL 持久化根目录，以及派生 `session-query.db` 索引的父目录 |
-| `persistenceCompression` | `'zstd'` | JSONL 产物编码（`'zstd'` 或原始 `'none'`） |
-| `sessionReferences` | 服务默认值 | 路由到 `dsh-session-reference` 的跨会话候选项与快照限制 |
-| `welcome` | `ready.` | TUI 副标题 |
-| `resumeCommand` | 无 | 退出和无宿主回退的命令模板；选择器本身使用会话查询与宿主移交 |
-| `ui` | 拥有者默认值 | 推理（reasoning）、颜色、卡片高度等 TUI 呈现设置 |
-| `resumeSessionId` | 无 | 要恢复的确切持久化会话 |
-
-新运行会创建 `main-session-<uuid>` 会话 id，并将它同时传给 TUI 与已配置的 agent。恢复运行会将两个组件都绑定到 `resumeSessionId`。TUI 先于主干挂载，因此它可以渲染匹配的配置启动失败，而不会留下空白终端。应用为 `/resume` 组合持久化和会话查询；嵌入宿主还可以提供 `tuiResumeHost`，用于原地移交进程。
-
-## 入口
-
-此包（package）不交付 bin。[`dsh`](../../../apps/cli/README.md) CLI 是终端入口：裸 `dsh` 启动已交付的 `examples/tui-agent/cordis.yml`（它挂载此组合包），而 `dsh --config <path-to-cordis.yml>` 启动另一个挂载此组合包的叶节点配置。它加载 cwd 下可选的 `.env`，驱动 Cordis Loader，并等待完整插件树。仓库安装了 Loader 的可选原生辅助程序，因此裸包说明符可以在纯 Node 下解析。

-
-## 模型体验
-
-### 交互式终端轮次
-
-#### 模型看到的内容
-
-每次非空、非命令的编辑器提交都会成为用户消息；运行中轮次内的提交成为 steering（中途引导）。斜杠命令输入和输出仍只面向人类，而已接受的 `/goal` 变更会追加领域拥有的模型可见状态。共享主干提供已配置的 persona、workspace 指令、skill 目录、目标控制和可见工具 schema。TUI 渲染本身对模型不可见。
-
-#### Token 影响
-
-用户、assistant 与工具历史按常规会话和压缩（compaction）规则增长。Header、卡片、计划、Markdown 样式和快捷键不增加 token。
-
-#### KV Cache 影响
-
-只要组合后的提示词、schema、路由和保留历史前缀保持稳定，就保持仅追加。组合方式变更与 compaction 可能从第一个变化的 token 起使复用失效。
-
-### 人类问题答案
-
-#### 模型看到的内容
-
-`ask_user_question` 会保留工具调用，以及 `dsh-tool-ask-user` 定义的精简答案或稳定中断错误。问题 overlay 只在终端显示。
-
-#### Token 影响
-
-只有已完成或失败的工具结果会增加保留 token。
-
-#### KV Cache 影响
-
-仅追加；答案跟在可复用请求前缀之后。

-- **只支持 TTY**：stdin 与 stdout 都必须是终端；自动化使用 `dsh-cli-demo`。
-- **一个已配置的终端会话**：transcript 与编辑器绑定到一个确切会话 id。
-- **应用集群固定不变**：JSONL 持久化与 ask-user 工具内置；不同策略需要另一种组合。
-- **批准机制独立存在**：此应用回答 `ctx.userInteraction`，而不是 `ctx.approval`；权限提示需要批准服务和回答方。

 ## 功能
 
-注册一个工具 `todo_write(todos: [{ content, status }])` 到 `ctx.tools`。模型每次调用都会发送完整列表，不存在部分更新或单项编辑。每次调用都会向调用 agent 的会话日志追加 `todo/write` 事件（完整列表快照），具体调用 `agent.session.append('todo/write', { todos })`；当前列表是最新的该类事件（回放时后写覆盖先写）。
+注册一个工具 `todo_write(todos: [{ content, status }])` 到 `ctx.tools`。模型每次调用都会发送完整列表，不存在部分更新或单项编辑。每次调用都会向调用 agent 的会话日志追加 `todo/write` 事件（完整列表快照），具体调用 `agent.session.append('todo/write', { todos })`；当前列表是最新的该类事件（回放时后写者胜）。
 
 `status` 是 `pending`、`in_progress` 或 `completed` 之一。
 
 ## 单一所有者
 
-该列表属于调用工具的唯一 agent 会话。不存在 subagent／共享／swarm scope：非 agent 调用方（没有 `exec.agent`）无处写入列表，因此会被拒绝。这是有意设置的 scope 限制，详见 Agent Note（agent 决策记录）。

 ## 验证
 
-除 schema 的类型／必填／枚举检查外，`execute` 还会拒绝空或重复的 `content`、同时存在多个 `in_progress` 任务的情况（连贯计划最多只有一个活跃任务），以及 `content`/`status` 之外的任何条目键——扩展条目形状（id、嵌套）会明确报错而不是被静默压平，保证落日志的快照与模型自认为写入的内容一致。列表的顺序及及时更新由模型依照工具描述负责。

-当组合挂载了 `ctx.sessionProjections`（[`@deepseek-ai/dsh-session-projection`](../../session-projection/session-projection/README.md)）时，本包在一个注入的子插件中注册 `todos` 投影单元：`init` = `null`（尚无写入）、`apply` = 从每个 `todo/write` 取整表，并在每个 `turn/start` 清为 `null`（当前有效计划；`turn/end` 保留刚完成的清单；其余事件都返回同一个状态引用）、`view` = 恒等、`stateVersion` = 2。该键在本包中合并进 `SessionProjectionMap`（经接口包的 `/types` 出口）；框架驱动该单元，载体通过历史尾页与 `session/projection` 推送帧提供该值。未挂载注册表的组合不受影响。生命周期理由见 [在下一轮次清空 todo 计划](../../../.agents/notes/implemented/feature/2026-07-28-todo-plan-clears-on-next-turn.md)。

 ## 导出形状
 
-函数／命名空间插件：导出 `name`/`inject`/`apply`，不提供默认导出。意外的 `export default` 会被 Loader 的 `unwrapExports` 折叠为默认导出，并导致 `inject` 丢失（参见 [docs/postmortem/0001](../../../docs/postmortem/0001-acp-default-export-drops-inject.md)）。

@@ -20,7 +20,7 @@ Placement and policy rulings folded into this decision:
 - **Dependency survey (hand-roll vs adopt).** Node's stdlib *is* the maintained cross-platform OS layer (`readdir(withFileTypes)`, `homedir`, path semantics); surveyed alternatives fail the dependency bar — file-manager packages (`node-file-manager`, `files-and-folders`, Syncfusion's provider) are whole HTTP apps (fit), drive-letter helpers (`drivelist` native addon, `windows-drive-letters` ~7y stale) fail health/proportionality. The browse backend is a thin adapter over stdlib.
 - **Hidden entries: return-and-flag.** The host stamps `hidden` (POSIX dot convention) and returns everything; the client filters. Display policy stays client-side, and the show-hidden toggle shipped as exactly that client-only change: a fixed-label footer toggle whose state lives in the pressed presentation (`aria-pressed` + check glyph), a dot-led path-draft prefix reveals the hidden entries it names, and the current selection is exempt from both the hidden and the prefix filter (it anchors the two-pane view). Windows' `FILE_ATTRIBUTE_HIDDEN` is not exposed by dirents — documented limitation until a native probe pays for itself.
 - **Path-editor cancel scope: the dialog card.** The browse client's path editor cancels on Escape and on focus leaving the card, both observed at a card-scope wrapper rather than the input — after Tab parks focus on a filtered row the input is off the event path, yet Escape must collapse the editor (not the dialog) and a later focus departure must still cancel. Non-cancel exemptions: window/tab focus loss, in-card focus moves, and pointer paths (rows and the toggle suppress focus steal on mousedown while editing). Separators for seeding and draft-tail filtering are inferred from `listing.home`; the wire-field alternative below records the deferred authoritative form. Combobox semantics between the editor and the list it filters (`aria-expanded`/`aria-controls`/active-descendant, result announcements) are likewise deferred — today they read to assistive tech as separate widgets.
-- **Navigation lands selection-anchored.** Away from the display root, the browse client's navigate (a crumb jump or a submitted path) lists the target's parent level with the target selected and its children on the right — two panes throughout, so a crumb jump reads as stepping back one pane rather than collapsing to a single column. The display root (home, or a rootward chain with no parent crumb) keeps the single wide level; the parent leg runs under the same supersession scope as the landing, and its failure falls back to the single-pane landing quietly — the target listed fine, and nobody asked to see the parent.
+- **Navigation lands selection-anchored, progressively.** Away from the display root (the same collapse the crumb header renders, so crumbs and pane shape never disagree), the browse client's navigate commits the target level the moment it arrives — the editor closes and loading ends on that first settlement, so an Enter-submitted navigation is never withdrawn waiting on more — and a parent leg then upgrades the landing in place: the target's actual parent-level entry re-selected (platform case folding on Windows), its children on the right, so a crumb jump reads as stepping back one pane rather than collapsing to a single column. The parent leg runs under the landing's supersession scope and is aborted on the wire by any newer intent; a failed parent leg, or a truncated parent window lacking the target, leaves the committed single-pane landing — the upgrade must never orphan the selection it exists to anchor.
 - **Symlinks: follow for enterability.** `stat` probes symlinks (broken/cyclic → skipped); crumbs keep the logical path the operator navigated, and `workspace.create` already canonicalizes via realpath at adoption.
 - **Listing levels are bounded, and streamed.** One `list` call returns at most `maxEntries` rows (config, default 1000 — GitHub's web-UI directory-listing bound). The level streams via `opendir` into a name-sorted window of `maxEntries + 1` candidates, so memory stays O(maxEntries) and enterability probing touches only windowed candidates; the wire `DirectoryListing` carries a required `truncated` flag so the client states incompleteness instead of silently missing tail entries. A windowed broken symlink is not backfilled from beyond the window — the eviction already marks the level truncated. Window insertion is binary with an O(1) full-window tail rejection (an oversized level must not pay a window scan per dirent), and `list(path, signal)` threads the carrier's request signal so a scan of a stalled network directory cannot outlive a disconnected caller — every await in the scan (open, each read, each symlink probe) races the signal, an aborted exit abandons rather than awaits the close (Node queues close behind in-flight reads), and abandoned settlements are swallowed so cleanup can never surface as an unhandled rejection. An unbounded level is a memory/responsiveness hole for large or adversarial directories.
 - **Whole-filesystem scope, no roots config.** `workspace.create` accepts arbitrary paths and the API serves bash-driving methods, so a browse root would be UX scoping, not a boundary; configurability without a consumer fails the evidence bar. Deferred until a deployment needs it.

 - **依赖调研（手写 vs 引入）。** Node 标准库本身就是维护中的跨平台 OS 层（`readdir(withFileTypes)`、`homedir`、路径语义）；调研过的替代品都过不了依赖门槛——文件管理器包（`node-file-manager`、`files-and-folders`、Syncfusion 的 provider）是整套 HTTP 应用（契合度不过），盘符工具（原生插件 `drivelist`、约七年未更的 `windows-drive-letters`）健康度／比例失当。browse 后端是标准库上的薄适配。
 - **隐藏条目：返回并打标。** 宿主标注 `hidden`（POSIX 点前缀约定）并返回全部条目；客户端过滤。展示策略留在客户端，"显示隐藏"开关正是作为这一纯客户端改动落地：标签固定的 footer 开关，其状态由按下态呈现承载（`aria-pressed` + 勾选符号）；以点开头的路径草稿前缀会显出它所指名的隐藏条目；当前选中项则不受隐藏与前缀两种过滤影响（它锚定着双栏视图）。Windows 的 `FILE_ATTRIBUTE_HIDDEN` 不被 dirent 暴露——记为限制，直到原生探测值回其成本。
 - **路径编辑器的取消范围：对话框卡片。** browse 客户端的路径编辑器在按 Escape 与焦点离开卡片时取消，两者都在卡片范围的包装层而非输入框上监听——Tab 把焦点停到某个过滤命中的行之后，输入框已不在事件路径上，但 Escape 仍须收起编辑器（而非对话框），其后的焦点离开也仍须取消。不取消的豁免：窗口／标签页失焦、卡片内焦点移动，以及指针路径（编辑期间行与开关在 mousedown 时抑制焦点夺取）。预填与草稿末段过滤所用的分隔符从 `listing.home` 推断；下文的线上字段替代方案记录了被延期的权威形态。编辑器与其过滤的列表之间的 combobox 语义（`aria-expanded`／`aria-controls`／active-descendant、结果播报）同样被延期——目前二者在辅助技术看来是彼此独立的控件。
-- **导航以选中项为锚落地。** 在展示根之外，browse 客户端的导航（crumb 跳转或提交的路径）列出目标的父层级，选中目标并在右侧展示其子项——全程双栏，因此 crumb 跳转读作后退一栏，而不是塌缩成单列。展示根（home，或没有父 crumb 的抵根链）保持单个宽层级；父层级这一程与落地共用同一 supersession 范围，其失败会静默回退到单栏落地——目标本身列举无误，本也没有人要求查看父层级。
+- **导航以选中项为锚、渐进落地。** 在展示根之外（与 crumb 头部渲染的是同一塌缩，因此 crumb 与分栏形态永不相左），browse 客户端的导航在目标层级到达的那一刻即提交它——这次首个落定即关闭编辑器并结束加载，因此 Enter 提交的导航绝不会为等待更多内容而被撤回——随后父层级这一程就地升级这次落地：重新选中目标在父层级中的实际条目（Windows 上按平台惯例折叠大小写），右侧展示其子项，因此 crumb 跳转读作后退一栏，而不是塌缩成单列。父层级这一程在落地的 supersession 范围下运行，任何较新的意图都会在线上将其中止；父层级这一程失败，或被截断的父窗口缺少目标时，都保留已提交的单栏落地——升级的存在正是为了锚定选中项，绝不能反而让它悬空。
 - **符号链接：为可进入性而跟随。** 用 `stat` 探测符号链接（断链／循环→跳过）；面包屑保留操作者导航的逻辑路径，`workspace.create` 在接纳时本就做 realpath 规范化。
 - **列举层级有上限，且流式处理。** 单次 `list` 至多返回 `maxEntries` 行（配置项，默认 1000——GitHub 网页端目录列举的同一上限）。层级经 `opendir` 流入一个按名排序、容量 `maxEntries + 1` 的候选窗口，内存保持 O(maxEntries)，可进入性探测只触及窗口内候选；线上 `DirectoryListing` 携带必填的 `truncated` 标志，让客户端明示不完整而不是静默缺尾。窗口内的断链符号链接不从窗口外回填——发生过驱逐本身已把层级标记为截断。窗口插入为二分查找、满窗尾部单次比较即拒绝（超大层级不能为每个 dirent 付出一次全窗扫描），且 `list(path, signal)` 透传载体的请求信号，滞塞网络目录的扫描不会在调用方断连后继续存活——扫描中的每个 await（打开、每次读取、每次符号链接探测）都与信号赛跑，中止路径放弃而非等待 close（Node 会把 close 排在在飞读取之后），被放弃的 settlement 全部吞掉，清理不会以未处理拒绝的形式冒出。无上限的层级对超大或恶意构造的目录就是内存／响应性漏洞。
 - **全盘可浏览，不做 roots 配置。** `workspace.create` 接受任意路径且 API 本就提供驱动 bash 的方法，浏览根只会是 UX 范围而非边界；没有消费方的可配置性过不了证据门槛。等到有部署需要再做。

 Behavior facts: listings return **directories only**, name-sorted, with symlinks-to-directories followed (broken/cyclic links skipped — the probe `stat` failing means "not enterable") and a host-owned `hidden` flag (POSIX dot convention) left for the client to act on; `crumbs` is the root-to-target ancestor chain, the root crumb labeled by its full path (`/`, `C:\`); an absent `list` path means the host account's home directory. `createDirectory` is non-recursive (a missing parent is a real failure, not a level to invent) and validates the name as a single non-blank segment even when called directly, mirroring the wire schema's fence. Both primitives reject an explicit path that is not fully qualified — relative forms, and on Windows the rooted drive-less forms (`\foo`, `/foo`) and incomplete UNC prefixes (`\\`, `\\server`) that `isAbsolute` accepts — with `directory-unreadable`/`directory-create-failed`, instead of letting `resolve` rebase it under the host process cwd or current drive. One `list` call returns at most `maxEntries` rows (config, default 1000 — the bound GitHub's web UI applies to directory listings), and the level streams through a bounded window so memory stays O(maxEntries) no matter how many children the directory holds: a cut level keeps the name-sorted head, counts hidden rows against the bound, probes only windowed candidates, and reports `truncated: true` so the client can say the level is incomplete (a windowed broken symlink is not backfilled from beyond the window — the eviction already marks the level truncated); window insertion is binary with an O(1) full-window tail rejection, and `list` threads the caller's `AbortSignal` so a disconnect or timeout stops the scan instead of letting it outlive the caller. Failures throw the seam's typed `DirectoryPickerError`. Policy rationale: [the directory-picker capability seam Agent Note](../../../.agents/notes/implemented/architecture/2026-07-28-directory-picker-capability-seam.md).

 `@deepseek-ai/dsh-tool-bash-persistent` consumes `ctx.pty` and registers one `bash(command)` tool. It lazily creates one interactive shell per exact Agent and serializes that owner's calls. Cwd, exported variables, activated environments, functions, and background jobs persist. Random private markers delimit command output. Retained scrollback is paged backward to recover the command's original prefix; a dropped prefix is reported explicitly. Timeout or cancellation closes the shell before another call can reuse uncertain state, and model-visible timeout/exit results disclose that reset. The configurable description defaults to persistence facts only, so network and package-mirror claims remain deployment-owned.
 
-`@deepseek-ai/dsh-tool-str-replace-editor` independently consumes `ctx.fs` and registers `str_replace_editor` with `view`, `create`, `str_replace`, and `insert`. It provides numbered text views, filtered two-level directory listings, unique literal replacement, canonical insertion boundaries, and bounded output. The public schema and failures use only `old_str`; canonical mode requires absolute paths and expands tabs before mutations. Deployments with an intentional session-cwd contract can disable the absolute-path requirement. The plugin can compose with persistent Bash, one-shot Bash, sandboxed Bash, or no shell.

 `dsh-system-prompt` accepts `includeHarnessIdentity: false`, while `dsh-agent-spine-demo` forwards that setting and accepts `toolBash: false`. A deployment can therefore own an exact persona and replace the spine's native Bash without duplicate prompt or tool registrations. Existing defaults remain unchanged.

-The schema provides `view`, `create`, `str_replace`, and `insert`. File views use one-based line numbers; directory views omit hidden, dependency, and Python-cache entries and descend two levels. Replacement requires one unique literal match and reports errors only in the public `old_str` vocabulary. Insert follows the selected zero-based insertion boundary without adding an implicit trailing newline.

Insert follows the selected zero-based insertion boundary without adding an implicit trailing newline. Mutations preserve tabs outside the requested edit.

 - Operations target UTF-8 text; binary files are unsupported.
 - `str_replace` intentionally rejects zero or multiple matches and has no `replace_all` argument.
-- Canonical mode (`expandTabsOnMutation: true`) expands tabs in the entire file before replacement or insertion, including lines outside the edited region. Set it to `false` for Makefiles and other tab-sensitive files.
 - Every mutation goes through `fs/write-intent` or `fs/edit-intent`, resolves the current session sandbox policy, and delegates enforcement to the mounted filesystem and policy plugins.

 Bringing up a new `packages/client/<name>` plugin package (ui-workspace is the latest walked example; ui-sidebar/ui-question are good skeletons to copy):
 
 1. **Package skeleton**: `package.json` (`@deepseek-ai/dsh-client-<name>`, exports `.`/`./invariant`/`./client`/`./src/*`/`./package.json`, `dshClient` manifest, `files` list), `tsconfig.json` (extends `tsconfig.base.client.json`, one `references` entry per workspace dependency plus `support/invariants`), `tsdown.config.ts` (`clientBundle(id, ['lib/types/index.js', 'lib/types/invariant.js'])`), `src/index.ts` (empty node-half apply), `src/invariant.ts` (companion with a real reason), `src/css-modules.d.ts` when using CSS Modules, `README.md` with the Model Experience section.
-2. **Three registration surfaces, all required** (missing any one fails at a different, later point): the `tsconfig.client.json` aggregate `references` entry; a `dshClient` row in `apps/cli/base.cordis.yml`; an `apps/cli/package.json` dependency (Loader resolves each config-tree package against the composing app's URL — a row whose package is not an `apps/cli` dependency fails to import). `pnpm-workspace.yaml` already globs `packages/*/*`.

 3. **dshClient manifest semantics**: `platform: 'web'` always; `immediately: true` only for stage-one-prefetch infrastructure rows. `inject` lists package-name dependency edges — they are **informational only** (preflight display, HMR diffing); they do not sequence entry activation or apply order. Activation order is cordis fiber inject waiting on *services*, nothing else.
 4. **Registering into another package's slot**: if the declaring host provides no waitable service, your apply's order relative to the host's is unconstrained — a bare `slots.register` into its slot races boot (intermittent `slot "..." is not declared` page failures). Register with declaration-aware deferral: check `ctx.slots.spec(name)`, otherwise `ctx.slots.subscribe(name)` and register on the declaration event (SlotCore supports subscribing ahead of declaration); make the registration idempotent, and unsubscribe + dispose in the effect disposer. Only take a service edge in `inject` when the host actually provides one (ui-question → `'conversation'` is that case).
 5. Rebuild the bundle (`pnpm --filter <pkg> bundle`) before probing a live `dsh web` server — the registry serves `lib/client.js`, not sources.

 `dsh meta` is that same TUI with this harness checkout as the workspace, so working on dsh itself needs no `cd`. It chdirs to the checkout root — resolved from the launcher's real path, the same root the source-path prompt section names — after both `.env` layers are loaded, so environment precedence is unchanged while the session cwd and HMR watch root move together. Meta always starts a fresh session and accepts no default-surface options; use ordinary `dsh --resume <id>` to resume a persisted session.
 
-`dsh migrate` and `dsh upgrade` are guided fresh-session entries over the default TUI surface: each mints a fresh session in the invoking directory and seeds its first turn with a bundled skill (`dsh-migrate` for migrating from another coding agent — opencode, pi, Claude Code, Codex; `dsh-upgrade` for upgrading this checkout), exactly as if the user typed `/skill:<name>`. 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 <id>` of the session is an ordinary TUI session with no re-injection.

 The Web and headless surfaces boot `base.cordis.yml` plus `web.cordis.yml`; `dsh web --config <path>` adds an overlay after the web surface defaults. 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 <path>` overrides it, load applicable `AGENTS.md`/`CLAUDE.md` instructions into each agent-loop request prefix with a 65,536-byte render budget, and opt into first-message model titles. 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`).

-name: dsh-migrate
-description: Migrate a user's setup from another coding agent (opencode, pi, Claude Code, Codex) to DSH — porting instruction files, custom commands and skills, hooks, MCP servers, and API/env configuration into their DSH equivalents. Use when the user asks to migrate, switch, or move from another coding agent to DSH.
----
-
-# DSH Migrate
-
-Move a user's existing coding-agent setup onto DSH: instruction files, custom commands, skills, hooks, MCP servers, and API/environment configuration. Port only what has a real DSH equivalent; tell the user plainly when something has none.
-
-## First: identify the source
-
-Ask which agent the user is migrating from if they have not said: **opencode**, **pi**, **Claude Code**, or **Codex**. The mapping differs per source. Then locate that agent's config (ask the user, or inspect the obvious locations: `~/.claude/` and `.claude/` for Claude Code, `~/.codex/` and `.codex/` for Codex, the opencode/pi config dir the user names). Read what exists before proposing changes; never invent files the user does not have.
-
-## DSH targets
-
-Every migration lands in one of these DSH surfaces. Verify the exact path against the running install rather than assuming.
-
-- **Workspace instructions**: DSH reads `AGENTS.md` and `CLAUDE.md` (and `AGENTS.local.md` / `CLAUDE.local.md`) from the project, walking up to the project root, plus a user-global `~/.dsh/AGENTS.md`. `CLAUDE.md` is read as-is, so a Claude Code project needs no rename.
-- **Personal overlay** (user-global, applies to every DSH session): the Harness home `~/.dsh/` holds `config.yaml` (a top-level YAML array of Loader patch entries that patch the booted plugin tree), `.env` (fills environment gaps only — ambient env and the invoking directory's `.env` win), `AGENTS.md`, and `skills/`.
-- **Skills**: directory-bundle or flat-Markdown skills load from `.dsh/skills/` and `.agents/skills/` in the project, and `~/.dsh/skills/` and `~/.agents/skills/` for the user. Personal skills go in `~/.dsh/skills/<name>/SKILL.md`. Use the `skill-creator` skill to author them.
-- **Hooks**: DSH runs a mapped subset of an existing Claude Code or Codex hook config through compatibility bridges — no rewrite needed for the supported subset. See the per-source sections.
-- **MCP servers**: DSH has no native MCP client. Reach MCP servers through the `mcporter` skill / CLI, which can call servers already configured for other tools.
-- **API / model config**: DSH uses `DEEPSEEK_API_KEY` (and optional `DEEPSEEK_BASE_URL`) from `.env` (root, invoking directory, or `~/.dsh/.env`). Model and provider are chosen in the booted `cordis.yml` / personal overlay, not per-provider config files.
-
-## Per-source mapping
-
-### Claude Code
-
-- `CLAUDE.md` → read as-is by DSH workspace instructions; keep it, or consolidate into `AGENTS.md`. User-global rules → `~/.dsh/AGENTS.md`.
-- `.claude/hooks.json` (or a settings file's `hooks` key) → the `@deepseek-ai/dsh-hooks-claude` bridge runs the mapped command-hook subset on DSH's interception seams, with `${CLAUDE_PLUGIN_ROOT}` / `${CLAUDE_PROJECT_DIR}` substitution. Add it to the booted `cordis.yml` (or personal overlay) pointing `configPath` at the existing file. Anything outside the mapped subset should become a native DSH plugin, not a shimmed hook.
-- Slash commands → DSH commands are plugin-provided; there is no drop-in import. Reimplement genuinely needed ones as skills (`~/.dsh/skills/`) or plugins.
-- MCP servers in Claude config → use `mcporter` to reach them; DSH has no native MCP.
-- `ANTHROPIC_API_KEY` etc. do not transfer; DSH is DeepSeek-backed via `DEEPSEEK_API_KEY`.
-
-### Codex
-
-- Codex `AGENTS.md` → DSH already reads `AGENTS.md`; keep it. User-global → `~/.dsh/AGENTS.md`.
-- Codex hook config → the `@deepseek-ai/dsh-hooks-codex` bridge runs a deliberate subset (`PreToolUse`, `PostToolUse`, `SessionStart`, `UserPromptSubmit`, `Stop`; regex-only matchers; no plugin env injection; no pre-tool approval/rewrite). Add the bridge to the booted config with `configPath` at the existing Codex hooks file. State the unsupported points to the user rather than implying full parity.
-- MCP servers → `mcporter`.
-- API/env → `DEEPSEEK_API_KEY` in `.env`.
-
-### opencode / pi
-
-- These have no compatibility bridge. Port by concept, not by file:
-  - Agent/system instructions → `AGENTS.md` (project) and `~/.dsh/AGENTS.md` (user-global).
-  - Provider/model and any plugin-style tuning → the booted `cordis.yml` or `~/.dsh/config.yaml` overlay patches; API keys → `.env`.
-  - Reusable prompts/commands → skills under `~/.dsh/skills/`.
-  - MCP servers → `mcporter`.
-- pi has no native MCP by design; the `mcporter` route is the same as for DSH.
-
-## Do the migration
-
-1. Confirm the source agent and read its actual config.
-2. For each capability (instructions, hooks, commands/skills, MCP, API/env), map it to the DSH target above, or tell the user it has no equivalent.
-3. Write the ported files (`AGENTS.md`, `~/.dsh/AGENTS.md`, `~/.dsh/config.yaml`, `~/.dsh/.env`, skills). For hook bridges, add the plugin entry to the booted config.
-4. Verify: hooks need the bridge plugin present in the running tree; MCP needs `mcporter` reachable; API needs `DEEPSEEK_API_KEY` set. Test in a real DSH session, not just on paper.
-5. Summarize what was ported, what was reimplemented, and what has no DSH equivalent.

By default that final list is `~/.dsh/config.yaml`; `dsh --config <path>` replaces the personal list with the named overlay. `dsh --config-replace <path>` instead boots the named file as the complete tree, without shipped or personal layers. `dsh web --config <path>` adds its overlay after the shared base and Web surface defaults and before Web profile and CLI-flag patches.
+
+A patch replaces a row's entire `config` value; it does not deep-merge keys. For example, patching `llm-deepseek` with only `config: { thinking: disabled }` also removes that row's configured `apiKey` and `baseURL`, so restate every key the row must retain.
+
 ## JavaScript values and environment variables
 
 The Cordis loader evaluates runtime expressions tagged with `!!js`. Keep API keys and other secrets in the gitignored `.env` file at the repository root, never in committed configuration.

 An overlay or `--config` tree that named `@deepseek-ai/dsh-tui-demo`, or patched the `tui-agent` row, no longer resolves. Overlays now patch the row that owns each key: the model route on `agent-loop`, the persona on `system-prompt`, presentation on `tui`.
 
-A patch whose `id` matches no row stays a Loader warning rather than an error. That is deliberate: one personal overlay is shared across surfaces, and `insert` rows match nothing by design, so a row that exists only under `web` must not fail the TUI's boot.

-`dsh web` gains `--config`, threaded into `AppCLIEntry` as an extra overlay. `AppCLIEntry` reads both the base and its surface overlay when recovering row defaults for its own patch merge, since a flag override must preserve the overlay's other fields on the same row.
+`dsh web` gains `--config`, threaded into `AppCLIEntry` as an extra overlay. Web keeps sandboxed Bash and filesystem providers plus approval, permission presets, directory picking, and browser permission UI; the overlay disables the shared local providers because patches can disable rows but cannot delete them. The TUI query index uses a unique process-local temporary database because the SQLite backend requires one writer owner. It is a disposable derived index rebuilt by each process; `/resume` lists the underlying corpus directly and does not depend on index reuse. `AppCLIEntry` reads both the base and its surface overlay when recovering row defaults for its own patch merge, since a flag override must preserve the overlay's other fields on the same row.
 
 ## Verification
 
-Composition is checked by booting each tree through the real Loader and inspecting settled entries, not by reading YAML: the TUI settles 55 entries and web 75, both with zero unloaded or unsettled rows, and web's `httpServer` up. The three-layer case (`base` + `tui` + `code-mode`) confirms `tools.mode` reaching `code` over the TUI overlay's `native`.

 All eight terminal snapshot scenarios replay byte-identically after moving, and the 14-case PTY smoke passes, including two cases that assert a personal overlay reaches an **inserted** row — the behavior the vendored `plugin-include` fix enables ([`vendor/README.md`](../../../../vendor/README.md) local modification 8, covered by `packages/ui/app-boot/tests/config-reload.spec.ts`).

 ## 验证
 
-组合的正确性通过用真实 Loader 启动每棵树并检查已就绪的条目来核对，而不是靠阅读 YAML：TUI 就绪 55 个条目、web 就绪 75 个，两者都没有未加载或未就绪的配置项，且 web 的 `httpServer` 已启动。三层叠加的情形（`base` + `tui` + `code-mode`）确认 `tools.mode` 越过 TUI overlay 的 `native` 达到了 `code`。

-- **exe (production)** — a single-file Node executable `dsh-jsonrpc-agent-pkg-<platform>-<arch>` plus its native `-spawn-helper` sibling (platform: `linux`/`macos`; arch: `x64`/`arm64`). The helper is required by `node-pty`; both files are built and validated as one runtime product. No Node installation is needed on the target machine. This is the only carrier that ships in wheel distributions; this package does not publish sdists.
+- **exe (production)** — a single-file Node executable `dsh-jsonrpc-agent-pkg-<platform>-<arch>` plus its native `-spawn-helper` sibling (platform: `linux`/`macos`; arch: `x64`/`arm64`). The helper is required by `node-pty`; both files are built as one runtime product, and ELF or thin Mach-O headers must match the target. No Node installation is needed on the target machine. This is the only carrier that ships in wheel distributions; this package does not publish sdists.
 - **node (dev-only)** — the full deploy closure under `runtime/node/` (`package.json` + `node_modules/`), executed as `node runtime/node/node_modules/@deepseek-ai/dsh-jsonrpc-demo/lib/bin.js` on a system Node >= 22.19. It is the current checkout's source build, meant for repo-local development and verification only; it is never selected automatically and is excluded from distributions.
 
 Both carriers hold the same content, defined once: the [package.json](package.json) at this package's root is the deploy root of the single-exe pipeline — a pure dependency manifest (no code of its own) whose dependency closure IS both the plugin set compiled into the exe and the tree materialized into `runtime/node/`. Adding a plugin to the distribution means adding one dependency line there and rebuilding.

InputBar renders the seat in its trailing controls immediately before the pending indicator and primary button; the seat receives the bar's `locked` owner prop and session scope. `@deepseek-ai/dsh-client-ui-model` occupies that seat and also contributes `/model` over the same directory.

@@ -20,7 +20,7 @@ Placement and policy rulings folded into this decision:
 - **Dependency survey (hand-roll vs adopt).** Node's stdlib *is* the maintained cross-platform OS layer (`readdir(withFileTypes)`, `homedir`, path semantics); surveyed alternatives fail the dependency bar — file-manager packages (`node-file-manager`, `files-and-folders`, Syncfusion's provider) are whole HTTP apps (fit), drive-letter helpers (`drivelist` native addon, `windows-drive-letters` ~7y stale) fail health/proportionality. The browse backend is a thin adapter over stdlib.
 - **Hidden entries: return-and-flag.** The host stamps `hidden` (POSIX dot convention) and returns everything; the client filters. Display policy stays client-side, and the show-hidden toggle shipped as exactly that client-only change: a fixed-label footer toggle whose state lives in the pressed presentation (`aria-pressed` + check glyph), a dot-led path-draft prefix reveals the hidden entries it names, and the current selection is exempt from both the hidden and the prefix filter (it anchors the two-pane view). Windows' `FILE_ATTRIBUTE_HIDDEN` is not exposed by dirents — documented limitation until a native probe pays for itself.
 - **Path-editor cancel scope: the dialog card.** The browse client's path editor cancels on Escape and on focus leaving the card, both observed at a card-scope wrapper rather than the input — after Tab parks focus on a filtered row the input is off the event path, yet Escape must collapse the editor (not the dialog) and a later focus departure must still cancel. Non-cancel exemptions: window/tab focus loss, in-card focus moves, and pointer paths (rows and the toggle suppress focus steal on mousedown while editing). Separators for seeding and draft-tail filtering are inferred from `listing.home`; the wire-field alternative below records the deferred authoritative form. Combobox semantics between the editor and the list it filters (`aria-expanded`/`aria-controls`/active-descendant, result announcements) are likewise deferred — today they read to assistive tech as separate widgets.
-- **Navigation lands selection-anchored, progressively.** Away from the display root (the same collapse the crumb header renders, so crumbs and pane shape never disagree), the browse client's navigate commits the target level the moment it arrives — the editor closes and loading ends on that first settlement, so an Enter-submitted navigation is never withdrawn waiting on more — and a parent leg then upgrades the landing in place: the target's actual parent-level entry re-selected (platform case folding on Windows), its children on the right, so a crumb jump reads as stepping back one pane rather than collapsing to a single column.

The parent leg runs under the landing's supersession scope and is aborted on the wire by any newer intent; a failed parent leg, or a truncated parent window lacking the target, leaves the committed single-pane landing — the upgrade must never orphan the selection it exists to anchor. Known boundaries of the progressive shape: a pointer press landing exactly inside the one-RTT upgrade window can lose its click when the pressed row node is replaced (keyboard focus is re-parked on the re-selected row; the pointer window is accepted); slash-platform typed-case drift (macOS) misses the parent-entry match and keeps the single-pane landing; and navigate always relists both legs even when the target is the currently shown level — a crumb tap doubles as the refresh gesture, so freshness wins over reusing possibly-stale in-hand listings at the cost of up to two host scans.
 - **Symlinks: follow for enterability.** `stat` probes symlinks (broken/cyclic → skipped); crumbs keep the logical path the operator navigated, and `workspace.create` already canonicalizes via realpath at adoption.
 - **Listing levels are bounded, and streamed.** One `list` call returns at most `maxEntries` rows (config, default 1000 — GitHub's web-UI directory-listing bound). The level streams via `opendir` into a name-sorted window of `maxEntries + 1` candidates, so memory stays O(maxEntries) and enterability probing touches only windowed candidates; the wire `DirectoryListing` carries a required `truncated` flag so the client states incompleteness instead of silently missing tail entries. A windowed broken symlink is not backfilled from beyond the window — the eviction already marks the level truncated. Window insertion is binary with an O(1) full-window tail rejection (an oversized level must not pay a window scan per dirent), and `list(path, signal)` threads the carrier's request signal so a scan of a stalled network directory cannot outlive a disconnected caller — every await in the scan (open, each read, each symlink probe) races the signal, an aborted exit abandons rather than awaits the close (Node queues close behind in-flight reads), and abandoned settlements are swallowed so cleanup can never surface as an unhandled rejection. An unbounded level is a memory/responsiveness hole for large or adversarial directories.
 - **Whole-filesystem scope, no roots config.** `workspace.create` accepts arbitrary paths and the API serves bash-driving methods, so a browse root would be UX scoping, not a boundary; configurability without a consumer fails the evidence bar. Deferred until a deployment needs it.

 - **依赖调研（手写 vs 引入）。** Node 标准库本身就是维护中的跨平台 OS 层（`readdir(withFileTypes)`、`homedir`、路径语义）；调研过的替代品都过不了依赖门槛——文件管理器包（`node-file-manager`、`files-and-folders`、Syncfusion 的 provider）是整套 HTTP 应用（契合度不过），盘符工具（原生插件 `drivelist`、约七年未更的 `windows-drive-letters`）健康度／比例失当。browse 后端是标准库上的薄适配。
 - **隐藏条目：返回并打标。** 宿主标注 `hidden`（POSIX 点前缀约定）并返回全部条目；客户端过滤。展示策略留在客户端，"显示隐藏"开关正是作为这一纯客户端改动落地：标签固定的 footer 开关，其状态由按下态呈现承载（`aria-pressed` + 勾选符号）；以点开头的路径草稿前缀会显出它所指名的隐藏条目；当前选中项则不受隐藏与前缀两种过滤影响（它锚定着双栏视图）。Windows 的 `FILE_ATTRIBUTE_HIDDEN` 不被 dirent 暴露——记为限制，直到原生探测值回其成本。
 - **路径编辑器的取消范围：对话框卡片。** browse 客户端的路径编辑器在按 Escape 与焦点离开卡片时取消，两者都在卡片范围的包装层而非输入框上监听——Tab 把焦点停到某个过滤命中的行之后，输入框已不在事件路径上，但 Escape 仍须收起编辑器（而非对话框），其后的焦点离开也仍须取消。不取消的豁免：窗口／标签页失焦、卡片内焦点移动，以及指针路径（编辑期间行与开关在 mousedown 时抑制焦点夺取）。预填与草稿末段过滤所用的分隔符从 `listing.home` 推断；下文的线上字段替代方案记录了被延期的权威形态。编辑器与其过滤的列表之间的 combobox 语义（`aria-expanded`／`aria-controls`／active-descendant、结果播报）同样被延期——目前二者在辅助技术看来是彼此独立的控件。
-- **导航以选中项为锚、渐进落地。** 在展示根之外（与 crumb 头部渲染的是同一塌缩，因此 crumb 与分栏形态永不相左），browse 客户端的导航在目标层级到达的那一刻即提交它——这次首个落定即关闭编辑器并结束加载，因此 Enter 提交的导航绝不会为等待更多内容而被撤回——随后父层级这一程就地升级这次落地：重新选中目标在父层级中的实际条目（Windows 上按平台惯例折叠大小写），右侧展示其子项，因此 crumb 跳转读作后退一栏，而不是塌缩成单列。父层级这一程在落地的 supersession 范围下运行，任何较新的意图都会在线上将其中止；父层级这一程失败，或被截断的父窗口缺少目标时，都保留已提交的单栏落地——升级的存在正是为了锚定选中项，绝不能反而让它悬空。

 - **符号链接：为可进入性而跟随。** 用 `stat` 探测符号链接（断链／循环→跳过）；面包屑保留操作者导航的逻辑路径，`workspace.create` 在接纳时本就做 realpath 规范化。
 - **列举层级有上限，且流式处理。** 单次 `list` 至多返回 `maxEntries` 行（配置项，默认 1000——GitHub 网页端目录列举的同一上限）。层级经 `opendir` 流入一个按名排序、容量 `maxEntries + 1` 的候选窗口，内存保持 O(maxEntries)，可进入性探测只触及窗口内候选；线上 `DirectoryListing` 携带必填的 `truncated` 标志，让客户端明示不完整而不是静默缺尾。窗口内的断链符号链接不从窗口外回填——发生过驱逐本身已把层级标记为截断。窗口插入为二分查找、满窗尾部单次比较即拒绝（超大层级不能为每个 dirent 付出一次全窗扫描），且 `list(path, signal)` 透传载体的请求信号，滞塞网络目录的扫描不会在调用方断连后继续存活——扫描中的每个 await（打开、每次读取、每次符号链接探测）都与信号赛跑，中止路径放弃而非等待 close（Node 会把 close 排在在飞读取之后），被放弃的 settlement 全部吞掉，清理不会以未处理拒绝的形式冒出。无上限的层级对超大或恶意构造的目录就是内存／响应性漏洞。
 - **全盘可浏览，不做 roots 配置。** `workspace.create` 接受任意路径且 API 本就提供驱动 bash 的方法，浏览根只会是 UX 范围而非边界；没有消费方的可配置性过不了证据门槛。等到有部署需要再做。

 ## Decision
 
-**Composition is one flat config tree.** `apps/cli/base.cordis.yml` plus its surface overlay holds every row — the host runtime (32 rows), the `api-gateway` row, the `webserver` row, and the `dshClient` rows (the browser roster; the modules row is simultaneously a host row). No spine bundle: every plugin is one row and every config field is yml-editable. That stance later became repository-wide, with the rows both surfaces share factored into `apps/cli/base.cordis.yml` and each surface reduced to an overlay ([shared-base overlays](../simplification/2026-07-29-shared-base-config-overlays.md)). `--dev` appends the `dsh-client-hmr` row in code before the settle sweep — prod and dev differ by exactly that row. Row order carries no load semantics; activation is service-availability driven, and the boot compensates with a fail-loud triple: `assertEntriesLoaded` (import failures), `installFailLoud` (late apply rejections), and an all-ACTIVE sweep (PENDING fibers — cordis inject waiting has no timeout).

 **Boot glue is a class pair.** `AppCLIEntry` (apps/cli) and `AppWebEntry` (the shell kernel) hold only what must exist independently of cordis: argv facts, the composed patch set, the parsed boot manifest, the module system instance, loading-page handles — everything else lives in plugins. `AppCLIEntry.run()` is three stages: layered env (ambient > cwd `.env` > `$DSH_HOME/.env`, closing the defect above) → patch composition → Loader include boot plus the triple. `AppWebEntry.run()` mirrors it browser-side: parse `window.__DSH_BOOT__` into a `BootManifest` (two views: npm-package rows for the module table, cordis-plugin rows for entry composition; malformed wire throws), build the module system, render the loading page, prefetch the `immediately` tier in parallel with Context/Loader setup, **await the prefetch before creating entries** (materialization is `tree.import`'s synchronous require, unprotected by fiber inject waiting; cross-package require edges such as i18n → runtime/client need every immediately-tier factory registered first — an empirically found 10–25% boot race otherwise), adopt the modules entry, create the graph rows, settle, sweep.

 A plain shared-fixture module (the [testing-policy sanctioned shape](../../../../docs/testing.md)), not a package: the gate-worthy logic — replay derivation, session parsing, log scrubbing, persistence — lives in the gated packages `dsh-llm-replay`, `dsh-acp-snapshot`, and `dsh-session-persistence-jsonl`; what remains is boot wiring and browser glue, and chromium-driving code cannot hold per-file 100% coverage on the browserless coverage runners.

Setup rollback and ordinary close both dispose the Cordis tree before removing the two owned temp roots, attempt every cleanup independently, and report cleanup failures without masking the setup failure.

 Keyless model displacement is the disabled adapter row plus `installLlmReplay` filling the open seam on the settled root ctx in providers-catalog mode — never catch-all: with the adapter row disabled no adapter exists, so catch-all would leave `resolveModelInfo` unroutable and `compact-basic`'s post-step pressure check would warn every step instead of being provably inert (the published 128k `contextWindow` keeps it inert for small fixtures). The direct install rather than an inserted replay plugin row is deliberate: it returns the `ReplayHandle` the teardown consumption check needs. A scenario with no fixture leaves the seam empty, so a stray stream fails loud with NO_ADAPTER.

@@ -20,7 +20,7 @@ Placement and policy rulings folded into this decision:
 - **Dependency survey (hand-roll vs adopt).** Node's stdlib *is* the maintained cross-platform OS layer (`readdir(withFileTypes)`, `homedir`, path semantics); surveyed alternatives fail the dependency bar — file-manager packages (`node-file-manager`, `files-and-folders`, Syncfusion's provider) are whole HTTP apps (fit), drive-letter helpers (`drivelist` native addon, `windows-drive-letters` ~7y stale) fail health/proportionality. The browse backend is a thin adapter over stdlib.
 - **Hidden entries: return-and-flag.** The host stamps `hidden` (POSIX dot convention) and returns everything; the client filters. Display policy stays client-side, and the show-hidden toggle shipped as exactly that client-only change: a fixed-label footer toggle whose state lives in the pressed presentation (`aria-pressed` + check glyph), a dot-led path-draft prefix reveals the hidden entries it names, and the current selection is exempt from both the hidden and the prefix filter (it anchors the two-pane view). Windows' `FILE_ATTRIBUTE_HIDDEN` is not exposed by dirents — documented limitation until a native probe pays for itself.
 - **Path-editor cancel scope: the dialog card.** The browse client's path editor cancels on Escape and on focus leaving the card, both observed at a card-scope wrapper rather than the input — after Tab parks focus on a filtered row the input is off the event path, yet Escape must collapse the editor (not the dialog) and a later focus departure must still cancel. Non-cancel exemptions: window/tab focus loss, in-card focus moves, and pointer paths (rows and the toggle suppress focus steal on mousedown while editing). Separators for seeding and draft-tail filtering are inferred from `listing.home`; the wire-field alternative below records the deferred authoritative form. Combobox semantics between the editor and the list it filters (`aria-expanded`/`aria-controls`/active-descendant, result announcements) are likewise deferred — today they read to assistive tech as separate widgets.
-- **Navigation lands selection-anchored, progressively.** Away from the display root (the same collapse the crumb header renders, so crumbs and pane shape never disagree), the browse client's navigate commits the target level the moment it arrives — the editor closes and loading ends on that first settlement, so an Enter-submitted navigation is never withdrawn waiting on more — and a parent leg then upgrades the landing in place: the target's actual parent-level entry re-selected (platform case folding on Windows), its children on the right, so a crumb jump reads as stepping back one pane rather than collapsing to a single column. The parent leg runs under the landing's supersession scope and is aborted on the wire by any newer intent; a failed parent leg, or a truncated parent window lacking the target, leaves the committed single-pane landing — the upgrade must never orphan the selection it exists to anchor. Known boundaries of the progressive shape: a pointer press landing exactly inside the one-RTT upgrade window can lose its click when the pressed row node is replaced (keyboard focus is re-parked on the re-selected row; the pointer window is accepted); slash-platform typed-case drift (macOS) misses the parent-entry match and keeps the single-pane landing; and navigate always relists both legs even when the target is the currently shown level — a crumb tap doubles as the refresh gesture, so freshness wins over reusing possibly-stale in-hand listings at the cost of up to two host scans.

 - **Symlinks: follow for enterability.** `stat` probes symlinks (broken/cyclic → skipped); crumbs keep the logical path the operator navigated, and `workspace.create` already canonicalizes via realpath at adoption.
 - **Listing levels are bounded, and streamed.** One `list` call returns at most `maxEntries` rows (config, default 1000 — GitHub's web-UI directory-listing bound). The level streams via `opendir` into a name-sorted window of `maxEntries + 1` candidates, so memory stays O(maxEntries) and enterability probing touches only windowed candidates; the wire `DirectoryListing` carries a required `truncated` flag so the client states incompleteness instead of silently missing tail entries. A windowed broken symlink is not backfilled from beyond the window — the eviction already marks the level truncated. Window insertion is binary with an O(1) full-window tail rejection (an oversized level must not pay a window scan per dirent), and `list(path, signal)` threads the carrier's request signal so a scan of a stalled network directory cannot outlive a disconnected caller — every await in the scan (open, each read, each symlink probe) races the signal, an aborted exit abandons rather than awaits the close (Node queues close behind in-flight reads), and abandoned settlements are swallowed so cleanup can never surface as an unhandled rejection. An unbounded level is a memory/responsiveness hole for large or adversarial directories.
 - **Whole-filesystem scope, no roots config.** `workspace.create` accepts arbitrary paths and the API serves bash-driving methods, so a browse root would be UX scoping, not a boundary; configurability without a consumer fails the evidence bar. Deferred until a deployment needs it.

 - **隐藏条目：返回并打标。** 宿主标注 `hidden`（POSIX 点前缀约定）并返回全部条目；客户端过滤。展示策略留在客户端，"显示隐藏"开关正是作为这一纯客户端改动落地：标签固定的 footer 开关，其状态由按下态呈现承载（`aria-pressed` + 勾选符号）；以点开头的路径草稿前缀会显出它所指名的隐藏条目；当前选中项则不受隐藏与前缀两种过滤影响（它锚定着双栏视图）。Windows 的 `FILE_ATTRIBUTE_HIDDEN` 不被 dirent 暴露——记为限制，直到原生探测值回其成本。
 - **路径编辑器的取消范围：对话框卡片。** browse 客户端的路径编辑器在按 Escape 与焦点离开卡片时取消，两者都在卡片范围的包装层而非输入框上监听——Tab 把焦点停到某个过滤命中的行之后，输入框已不在事件路径上，但 Escape 仍须收起编辑器（而非对话框），其后的焦点离开也仍须取消。不取消的豁免：窗口／标签页失焦、卡片内焦点移动，以及指针路径（编辑期间行与开关在 mousedown 时抑制焦点夺取）。预填与草稿末段过滤所用的分隔符从 `listing.home` 推断；下文的线上字段替代方案记录了被延期的权威形态。编辑器与其过滤的列表之间的 combobox 语义（`aria-expanded`／`aria-controls`／active-descendant、结果播报）同样被延期——目前二者在辅助技术看来是彼此独立的控件。
-- **导航以选中项为锚、渐进落地。** 在展示根之外（与 crumb 头部渲染的是同一塌缩，因此 crumb 与分栏形态永不相左），browse 客户端的导航在目标层级到达的那一刻即提交它——这次首个落定即关闭编辑器并结束加载，因此 Enter 提交的导航绝不会为等待更多内容而被撤回——随后父层级这一程就地升级这次落地：重新选中目标在父层级中的实际条目（Windows 上按平台惯例折叠大小写），右侧展示其子项，因此 crumb 跳转读作后退一栏，而不是塌缩成单列。父层级这一程在落地的 supersession 范围下运行，任何较新的意图都会在线上将其中止；父层级这一程失败，或被截断的父窗口缺少目标时，都保留已提交的单栏落地——升级的存在正是为了锚定选中项，绝不能反而让它悬空。渐进形态的已知边界：指针按压若恰好落在单个 RTT 的升级窗口内，可能因所按行节点被替换而丢失点击（键盘焦点会重新停靠到重新选中的行上；指针的这段窗口则被接受）；斜杠平台的键入大小写偏差（macOS）会错过父层级条目匹配，保留单栏落地；且导航总是重新列举两程，哪怕目标就是当前展示的层级——crumb 点按兼作刷新手势，因此宁要新鲜度也不复用手头可能已陈旧的列举，代价是至多两次宿主扫描。

 - **符号链接：为可进入性而跟随。** 用 `stat` 探测符号链接（断链／循环→跳过）；面包屑保留操作者导航的逻辑路径，`workspace.create` 在接纳时本就做 realpath 规范化。
 - **列举层级有上限，且流式处理。** 单次 `list` 至多返回 `maxEntries` 行（配置项，默认 1000——GitHub 网页端目录列举的同一上限）。层级经 `opendir` 流入一个按名排序、容量 `maxEntries + 1` 的候选窗口，内存保持 O(maxEntries)，可进入性探测只触及窗口内候选；线上 `DirectoryListing` 携带必填的 `truncated` 标志，让客户端明示不完整而不是静默缺尾。窗口内的断链符号链接不从窗口外回填——发生过驱逐本身已把层级标记为截断。窗口插入为二分查找、满窗尾部单次比较即拒绝（超大层级不能为每个 dirent 付出一次全窗扫描），且 `list(path, signal)` 透传载体的请求信号，滞塞网络目录的扫描不会在调用方断连后继续存活——扫描中的每个 await（打开、每次读取、每次符号链接探测）都与信号赛跑，中止路径放弃而非等待 close（Node 会把 close 排在在飞读取之后），被放弃的 settlement 全部吞掉，清理不会以未处理拒绝的形式冒出。无上限的层级对超大或恶意构造的目录就是内存／响应性漏洞。
 - **全盘可浏览，不做 roots 配置。** `workspace.create` 接受任意路径且 API 本就提供驱动 bash 的方法，浏览根只会是 UX 范围而非边界；没有消费方的可配置性过不了证据门槛。等到有部署需要再做。

 CI: [`.github/workflows/build-exe-for-python-sdk.yml`](../../../../.github/workflows/build-exe-for-python-sdk.yml), triggered explicitly only — `workflow_dispatch`, or the `build-exe` label on a pull request; native builds on the three platforms linux-x64 / linux-arm64 (`ubuntu-24.04-arm`) / macos-arm64, with `~/.pkg-cache` cached; macOS ad-hoc signing is handled by pkg. Each leg drives a mock SSE model through the SDK with the default config and a custom `cordis.yml`, drives the exe directly over NDJSON JSON-RPC, verifies the JSONL and final response, and installs release-shaped wheels into a clean venv without `runtime_bin`; Linux additionally inspects GLIBC requirements and runs in a manylinux 2.28 container. A full three-target run retains four artifacts, each containing one release file: the platform-independent SDK wheel and three native runtime wheels; a subset dispatch retains the SDK wheel and selected runtime wheels. Bare executables and source bundles remain intermediate test inputs. [`.gitlab-ci.yml`](../../../../.gitlab-ci.yml) accepts only `python-vX.Y.Z` tag pipelines whose version matches the root `package.json`, builds one SDK wheel and three native runtime wheels, then a single serialized job checks and publishes all four to the project PyPI registry. Windows is a non-goal.
 
 ### Python SDK distribution: two carriers, exe for production, node for development
 
-The Python SDK lives at [`python/`](../../../../python/README.md): `python/sdk` (the client) + `python/sdk-runtime` (the runtime carrier package). The runtime package's data directory holds three kinds of content: the checked-in default `runtime/cordis.yml`, the build-injected platform exe, and the build-injected `runtime/node/` closure tree. `resolve_bundled_launch_args()` automatic resolution **finds the exe only**; the node carrier is enabled only by an explicit `DSH_RUNTIME_MODE=node` (running `runtime/node/node_modules/@deepseek-ai/dsh-jsonrpc-demo/lib/bin.js`, requiring a system node ≥22.19), positioned as the development-verification channel for members of this repo, and does not enter wheel distributions.

-[`scripts/build-python-release.py`](../../../../scripts/build-python-release.py) reads the authoritative stable `X.Y.Z` from the repository root `package.json` and stages both packages at that version, with the SDK depending exactly on `deepseek-harness-runtime-bin==X.Y.Z`. An optional `python-vX.Y.Z` release tag is a consistency assertion and is rejected when it differs from the repository version; the source `pyproject.toml` development sentinel never determines a release version. The SDK is a `py3-none-any` wheel; the wheel-only runtime package contains exactly one exe and uses one of `py3-none-manylinux_2_28_x86_64`, `py3-none-manylinux_2_28_aarch64`, or `py3-none-macosx_11_0_arm64`. Its Hatch hook rejects sdists, universal tags, mixed executable payloads, and unsupported platforms.

 The exe's "must be explicitly configured" hard semantic is unchanged; the zero-config experience is restored by the wrapper: when the caller gave no `cordis`, named no explicit runtime, and the environment has no `DSH_CORDIS_CONFIG`, the client explicitly injects the checked-in default `cordis.yml` (agent-core + preloaded llm-deepseek + JSONL persistence + bash-local + the `dsh-jsonrpc` serving entry, with `!!js` environment-variable fallbacks) via `DSH_CORDIS_CONFIG`.

Shell exit, timeout, or cancellation loses state. The editor delegates security and mutation policy to the mounted filesystem stack. Runtime-wheel consumers still need no Node installation, but the wheel now contains a main executable plus its private native helper rather than one physical file.

-- **exe (production)** — a single-file Node executable `dsh-jsonrpc-agent-pkg-<platform>-<arch>` plus its native `-spawn-helper` sibling (platform: `linux`/`macos`; arch: `x64`/`arm64`). The helper is required by `node-pty`; both files are built as one runtime product, and ELF or thin Mach-O headers must match the target. No Node installation is needed on the target machine.

No Node installation is needed on the target machine. This is the only carrier that ships in wheel distributions; this package does not publish sdists.
 - **node (dev-only)** — the full deploy closure under `runtime/node/` (`package.json` + `node_modules/`), executed as `node runtime/node/node_modules/@deepseek-ai/dsh-jsonrpc-demo/lib/bin.js` on a system Node >= 22.19. It is the current checkout's source build, meant for repo-local development and verification only; it is never selected automatically and is excluded from distributions.
 
 Both carriers hold the same content, defined once: the [package.json](package.json) at this package's root is the deploy root of the single-exe pipeline — a pure dependency manifest (no code of its own) whose dependency closure IS both the plugin set compiled into the exe and the tree materialized into `runtime/node/`. Adding a plugin to the distribution means adding one dependency line there and rebuilding.

 ## Testing
 
-The verification surface has three tiers. Mechanism tier: the measured conclusions for the `--sea` chain are embedded in the Decision sections (ESM dynamic import inside the VFS, single cordis instance, fail-loud config chain, `node:sqlite`, macOS ad-hoc signing runs). SDK tier: the complete keyless pytest suite covers the client protocol against a fake runtime peer, subprocess cleanup, absolute cwd propagation, dual-carrier launch, and carrier resolution; root CI runs it on Python 3.10. End-to-end tier: every platform build completes a turn against a mock endpoint through the default SDK path, a custom config, and the direct binary protocol, with final text and JSONL checked. The custom config additionally drives `run_code` and a zero-agent `workflow` through their real worker files inside the packaged VFS. The same build leg runs a committed executable-specific snapshot through the Python SDK: a keyless scripted model mounts a Cordis plugin that registers a tool, invokes that tool from `run_code`, runs a direct spawn subagent and a workflow that starts a second spawn child, then unmounts the plugin. The comparison normalizes the SDK result and notification stream plus the parent and two child JSONL logs. This harness stays separate from ACP's `pnpm run test:snapshot` because the protocols and build artifacts differ. The platform wheel is then installed in a clean venv and run without `runtime_bin`.

 Manual-driving caveat: the bin treats stdin EOF as "the client is gone" and disposes immediately, so a short-lived pipe aborts an in-flight turn — pipe-driven runs must keep stdin open until the turn ends.

 手工驱动注意：`bin` 将 stdin EOF 视为“客户端已离开”并立即 dispose，短命管道会中止进行中的轮次——管道驱动必须保持 stdin 打开，直到轮次结束。

@@ -19,7 +19,7 @@ Placement and policy rulings folded into this decision:
 - **Not the `ctx.fs` seam.** `packages/fs/` is the model/session-facing storage stack (policy events, sandbox-swappable backends). Riding it would couple GUI browsing to the model's confinement backend — swapping `fs-sandbox` for the model must never change GUI behavior — and OS facts (home anchoring, hidden conventions) are not storage primitives. The picker seam stays presentation-free and model-free; `packages/host/` is its consumer-domain home.
 - **Dependency survey (hand-roll vs adopt).** Node's stdlib *is* the maintained cross-platform OS layer (`readdir(withFileTypes)`, `homedir`, path semantics); surveyed alternatives fail the dependency bar — file-manager packages (`node-file-manager`, `files-and-folders`, Syncfusion's provider) are whole HTTP apps (fit), drive-letter helpers (`drivelist` native addon, `windows-drive-letters` ~7y stale) fail health/proportionality. The browse backend is a thin adapter over stdlib.
 - **Hidden entries: return-and-flag.** The host stamps `hidden` (POSIX dot convention) and returns everything; the client filters. Display policy stays client-side, and the show-hidden toggle shipped as exactly that client-only change: a fixed-label footer toggle whose state lives in the pressed presentation (`aria-pressed` + check glyph), a dot-led path-draft prefix reveals the hidden entries it names, and the current selection is exempt from both the hidden and the prefix filter (it anchors the two-pane view). Windows' `FILE_ATTRIBUTE_HIDDEN` is not exposed by dirents — documented limitation until a native probe pays for itself.
-- **Path-editor cancel scope: the dialog card.** The browse client's path editor cancels on Escape and on focus leaving the card, both observed at a card-scope wrapper rather than the input — after Tab parks focus on a filtered row the input is off the event path, yet Escape must collapse the editor (not the dialog) and a later focus departure must still cancel. Non-cancel exemptions: window/tab focus loss, in-card focus moves, and pointer paths (rows and the toggle suppress focus steal on mousedown while editing). Separators for seeding and draft-tail filtering are inferred from `listing.home`; the wire-field alternative below records the deferred authoritative form. Combobox semantics between the editor and the list it filters (`aria-expanded`/`aria-controls`/active-descendant, result announcements) are likewise deferred — today they read to assistive tech as separate widgets.

Combobox semantics between the editor and the list it filters (`aria-expanded`/`aria-controls`/active-descendant, result announcements) are likewise deferred — today they read to assistive tech as separate widgets. Focus parking is a card-wide invariant, not an editor-only one: every pick — editing or not, including right-pane advances and create landings whose columns are replaced — re-parks focus on the selection's row after commit, while Enter, an input-focused Escape, and a pick whose row vanished park on the crumb edit zone; keyboard traversal never falls out of the card (the Modal has no focus trap).
 - **Navigation lands selection-anchored, progressively.** Away from the display root (the same collapse the crumb header renders, so crumbs and pane shape never disagree), the browse client's navigate commits the target level the moment it arrives — the editor closes and loading ends on that first settlement, so an Enter-submitted navigation is never withdrawn waiting on more — and a parent leg then upgrades the landing in place: the target's actual parent-level entry re-selected (platform case folding on Windows), its children on the right, so a crumb jump reads as stepping back one pane rather than collapsing to a single column. The parent leg runs under the landing's supersession scope and is aborted on the wire by any newer intent; a failed parent leg, or a truncated parent window lacking the target, leaves the committed single-pane landing — the upgrade must never orphan the selection it exists to anchor. Known boundaries of the progressive shape: a pointer press landing exactly inside the one-RTT upgrade window can lose its click when the pressed row node is replaced (keyboard focus is re-parked on the re-selected row; the pointer window is accepted); on slash platforms (macOS) only a final-segment case drift misses the parent-entry match and keeps the single-pane landing, while ancestor-segment drift still matches — parent entry paths inherit the typed prefix — and lands two panes at the cost of the Home collapse; and navigate always relists both legs even when the target is the currently shown level — a crumb tap doubles as the refresh gesture, so freshness wins over reusing possibly-stale in-hand listings at the cost of up to two host scans.
 - **Symlinks: follow for enterability.** `stat` probes symlinks (broken/cyclic → skipped); crumbs keep the logical path the operator navigated, and `workspace.create` already canonicalizes via realpath at adoption.
 - **Listing levels are bounded, and streamed.** One `list` call returns at most `maxEntries` rows (config, default 1000 — GitHub's web-UI directory-listing bound). The level streams via `opendir` into a name-sorted window of `maxEntries + 1` candidates, so memory stays O(maxEntries) and enterability probing touches only windowed candidates; the wire `DirectoryListing` carries a required `truncated` flag so the client states incompleteness instead of silently missing tail entries. A windowed broken symlink is not backfilled from beyond the window — the eviction already marks the level truncated. Window insertion is binary with an O(1) full-window tail rejection (an oversized level must not pay a window scan per dirent), and `list(path, signal)` threads the carrier's request signal so a scan of a stalled network directory cannot outlive a disconnected caller — every await in the scan (open, each read, each symlink probe) races the signal, an aborted exit abandons rather than awaits the close (Node queues close behind in-flight reads), and abandoned settlements are swallowed so cleanup can never surface as an unhandled rejection. An unbounded level is a memory/responsiveness hole for large or adversarial directories.

 - **不用 `ctx.fs` seam。** `packages/fs/` 是面向模型／会话的存储栈（policy 事件、sandbox 可换后端）。骑上去会把 GUI 浏览耦合进模型的限制后端——为模型换 `fs-sandbox` 绝不能改变 GUI 行为——而 OS 事实（home 锚定、隐藏约定）也不是存储原语。picker seam 保持无展示、无模型；`packages/host/` 是它消费方域的家。
 - **依赖调研（手写 vs 引入）。** Node 标准库本身就是维护中的跨平台 OS 层（`readdir(withFileTypes)`、`homedir`、路径语义）；调研过的替代品都过不了依赖门槛——文件管理器包（`node-file-manager`、`files-and-folders`、Syncfusion 的 provider）是整套 HTTP 应用（契合度不过），盘符工具（原生插件 `drivelist`、约七年未更的 `windows-drive-letters`）健康度／比例失当。browse 后端是标准库上的薄适配。
 - **隐藏条目：返回并打标。** 宿主标注 `hidden`（POSIX 点前缀约定）并返回全部条目；客户端过滤。展示策略留在客户端，"显示隐藏"开关正是作为这一纯客户端改动落地：标签固定的 footer 开关，其状态由按下态呈现承载（`aria-pressed` + 勾选符号）；以点开头的路径草稿前缀会显出它所指名的隐藏条目；当前选中项则不受隐藏与前缀两种过滤影响（它锚定着双栏视图）。Windows 的 `FILE_ATTRIBUTE_HIDDEN` 不被 dirent 暴露——记为限制，直到原生探测值回其成本。
-- **路径编辑器的取消范围：对话框卡片。** browse 客户端的路径编辑器在按 Escape 与焦点离开卡片时取消，两者都在卡片范围的包装层而非输入框上监听——Tab 把焦点停到某个过滤命中的行之后，输入框已不在事件路径上，但 Escape 仍须收起编辑器（而非对话框），其后的焦点离开也仍须取消。不取消的豁免：窗口／标签页失焦、卡片内焦点移动，以及指针路径（编辑期间行与开关在 mousedown 时抑制焦点夺取）。预填与草稿末段过滤所用的分隔符从 `listing.home` 推断；下文的线上字段替代方案记录了被延期的权威形态。编辑器与其过滤的列表之间的 combobox 语义（`aria-expanded`／`aria-controls`／active-descendant、结果播报）同样被延期——目前二者在辅助技术看来是彼此独立的控件。

 - **导航以选中项为锚、渐进落地。** 在展示根之外（与 crumb 头部渲染的是同一塌缩，因此 crumb 与分栏形态永不相左），browse 客户端的导航在目标层级到达的那一刻即提交它——这次首个落定即关闭编辑器并结束加载，因此 Enter 提交的导航绝不会为等待更多内容而被撤回——随后父层级这一程就地升级这次落地：重新选中目标在父层级中的实际条目（Windows 上按平台惯例折叠大小写），右侧展示其子项，因此 crumb 跳转读作后退一栏，而不是塌缩成单列。父层级这一程在落地的 supersession 范围下运行，任何较新的意图都会在线上将其中止；父层级这一程失败，或被截断的父窗口缺少目标时，都保留已提交的单栏落地——升级的存在正是为了锚定选中项，绝不能反而让它悬空。渐进形态的已知边界：指针按压若恰好落在单个 RTT 的升级窗口内，可能因所按行节点被替换而丢失点击（键盘焦点会重新停靠到重新选中的行上；指针的这段窗口则被接受）；斜杠平台（macOS）上仅末段的大小写偏差会错过父层级条目匹配，保留单栏落地，而祖先段的偏差仍能匹配——父层级条目路径继承键入的前缀——并落地双栏，代价是 Home 塌缩；且导航总是重新列举两程，哪怕目标就是当前展示的层级——crumb 点按兼作刷新手势，因此宁要新鲜度也不复用手头可能已陈旧的列举，代价是至多两次宿主扫描。
 - **符号链接：为可进入性而跟随。** 用 `stat` 探测符号链接（断链／循环→跳过）；面包屑保留操作者导航的逻辑路径，`workspace.create` 在接纳时本就做 realpath 规范化。
 - **列举层级有上限，且流式处理。** 单次 `list` 至多返回 `maxEntries` 行（配置项，默认 1000——GitHub 网页端目录列举的同一上限）。层级经 `opendir` 流入一个按名排序、容量 `maxEntries + 1` 的候选窗口，内存保持 O(maxEntries)，可进入性探测只触及窗口内候选；线上 `DirectoryListing` 携带必填的 `truncated` 标志，让客户端明示不完整而不是静默缺尾。窗口内的断链符号链接不从窗口外回填——发生过驱逐本身已把层级标记为截断。窗口插入为二分查找、满窗尾部单次比较即拒绝（超大层级不能为每个 dirent 付出一次全窗扫描），且 `list(path, signal)` 透传载体的请求信号，滞塞网络目录的扫描不会在调用方断连后继续存活——扫描中的每个 await（打开、每次读取、每次符号链接探测）都与信号赛跑，中止路径放弃而非等待 close（Node 会把 close 排在在飞读取之后），被放弃的 settlement 全部吞掉，清理不会以未处理拒绝的形式冒出。无上限的层级对超大或恶意构造的目录就是内存／响应性漏洞。

@@ -15,7 +15,7 @@ This Agent Note introduces `@deepseek-ai/dsh-hook-protocol`, a **library** (not
 A new `packages/hooks/` group with `hook-protocol` as a pure library. It owns four primitive families and the `hook/*` session events; each bridge plugin (`dsh-hooks-claude`, `dsh-hooks-codex`) owns what genuinely differs.
 
 **Shared (here):**
-- **Matcher** — `compileMatchers(patterns, mode)`, `matcherDiagnostic(pattern, mode)`, and `matchesMatcher(pattern, query, mode)`. Pure `[A-Za-z0-9_|]+` patterns use the shared exact-match fast path (pipe = alternatives); the ONE remaining dialect axis is collapsed to `mode`: other Claude patterns use JavaScript `RegExp`, while other Codex patterns use Rust `regex`, including Rust-only syntax such as `(?i)`. Match-all on absent/`''`/`'*'`. Each bridge ignores unsupported events before group parsing, discards matcher fields on supported events without matcher subjects, collects the remaining runnable groups, and compiles their finite set of unique patterns ONCE. It reads validation diagnostics from that config registry: rejection disposes the registry before whole-config failure, while admission returns the SAME registry for hook-point matching and plugin-teardown disposal after detached runs drain. Codex valid instances and invalid diagnostics additionally use a versioned interner on the synchronous `rregex` CJS module, so one-shot calls and hook-protocol/Cordis reloads reuse them without putting state on `globalThis`. Because that dependency's WASM allocator does not shrink after `free()`, the interner deliberately retains at most `MAX_INTERNED_CODEX_REGEX_PATTERNS` (128) distinct non-literal patterns per process. At capacity, a new distinct pattern is rejected before native construction with a stable capacity/pattern/event diagnostic; known patterns remain usable and process restart resets the budget. The hard bound covers adversarial unique-pattern reloads without an unbounded cache, while direct library calls remain contained and never throw into the loop.
+- **Matcher** — `matcherDiagnostic(pattern, mode)` and `matchesMatcher(pattern, query, mode)`. The ONE axis the dialects differ on is collapsed to the `mode` parameter: `claude` treats a pure `[A-Za-z0-9_|]+` pattern as a literal (pipe = exact-match alternation) and anything else as a regex; `codex` is always an unanchored regex. Match-all on absent/`''`/`'*'`. Each bridge ignores unsupported events before group parsing, discards matcher fields on supported events without matcher subjects, validates the remaining runnable groups, and treats an invalid regex there as a whole-config load failure, with a stable dialect/pattern/event diagnostic; no hook listeners are registered. Runtime matching still contains an invalid regex as a non-match, so a direct library caller never throws into the loop.
 - **Execution** — `runHook(bash, hook, options)`. Runs a command hook through the `ctx.bash` seam rather than a bespoke `spawn`: the executor already provides the scrubbed-but-overridable env, process-group kills, and timeout the protocol needs, and `dsh-bash`'s `stdin`/`env` fields (added for exactly this) are the trusted-plugin surface an in-process bridge is allowed to use. It serializes the bridge-built payload to stdin (trailing newline iff CC), honors the hook's `timeoutSec` (else `DEFAULT_HOOK_TIMEOUT_MS`, the 10-minute reference default both dialects share), and never throws (an executor rejection becomes a non-blocking-error `HookOutput`).
 - **Decode** — `parseHookOutput(exit, stdout, stderr)`, the exit-code + structured-stdout codec, producing a dialect-neutral `HookOutput`. Exit `0` → lenient JSON parse of stdout; exit `2` → blocking error with `stderr` as the reason (surfaced as `decision: 'block'` so no caller needs a separate exit-code branch); other → non-blocking error. Parses the CC structured-stdout fields that have a consumer on some path (`continue`/`stopReason`/`decision`/`hookSpecificOutput.{permissionDecision,additionalContext,updatedInput}`/`systemMessage`); the bridge honors only the subset meaningful for its dialect. Fields with no consumer on any path are not parsed at all (CC's `suppressOutput` — hook stdout never enters a transcript here, so there is nothing to suppress; see [the tighten-hook-protocol-contract Agent Note](../simplification/2026-07-04-tighten-hook-protocol-contract.md)).
 - **Merge** — `mergeHookOutputs(outputs)`, folding multiple matched hooks into one most-restrictive `MergedHookOutcome`: permission precedence **deny > ask > allow**, halt sticky on the first `continue:false`, block reasons joined `\n\n`, context/system-messages accumulated in order.

 在 `packages/hooks/` 分组下新建 `hook-protocol` 作为纯库。它拥有四个原语族和 `hook/*` 会话事件；每个桥接插件（`dsh-hooks-claude`、`dsh-hooks-codex`）拥有真正不同的部分。
 
 **共享（本库）：**
-- **Matcher** — `compileMatchers(patterns, mode)`、`matcherDiagnostic(pattern, mode)` 与 `matchesMatcher(pattern, query, mode)`。纯 `[A-Za-z0-9_|]+` pattern 使用共享的精确匹配快速路径（管道符 = 多选）；剩余的唯一方言差异收敛为 `mode`：其他 Claude pattern 使用 JavaScript `RegExp`，其他 Codex pattern 使用 Rust `regex`，包括 `(?i)` 等 Rust 专属语法。缺省/`''`/`'*'` 匹配一切。每个桥接插件会在解析 group 前忽略不支持的事件，丢弃受支持但没有 matcher 匹配对象的事件所带字段，收集其余可运行 group，再将其中有限的唯一 pattern 集合只编译一次。它直接从该配置 registry 读取校验诊断：pattern 被拒绝时，会先释放 registry 再让整份配置加载失败；有效解析则把同一个 registry 交给各 hook 点匹配，并在插件 teardown 时先 drain 脱离运行，再释放它。Codex 的有效实例与无效诊断还会使用同步 `rregex` CJS 模块上带版本号的 interner，因此一次性调用及 hook-protocol／Cordis 重载都能复用它们，而无需把状态放在 `globalThis` 上。由于该依赖的 WASM 分配器在 `free()` 后也不会缩小，interner 会有意将每进程不同的非字面 pattern 上限设为 `MAX_INTERNED_CODEX_REGEX_PATTERNS`（128）。容量用满时，新的不同 pattern 会在原生构造前被包含容量／pattern／事件的稳定诊断拒绝；已知 pattern 仍可使用，重启进程会重置预算。硬上限可覆盖恶意唯一 pattern 重载而无需无界缓存，同时直接调用本库仍是收敛的，绝不向 agent loop（智能体循环）抛异常。
+- **Matcher** — `matcherDiagnostic(pattern, mode)` 与 `matchesMatcher(pattern, query, mode)`。两种方言的唯一差异收敛到 `mode` 参数：`claude` 将纯 `[A-Za-z0-9_|]+` pattern 视为字面量（管道符 = 精确匹配多选），其他 pattern 视为正则；`codex` 始终使用未锚定正则。缺省/`''`/`'*'` 匹配一切。每个桥接插件会在解析 group 前忽略不支持的事件，丢弃受支持但没有 matcher 匹配对象的事件所带字段，校验其余可运行 group；其中任何无效正则都会导致整份配置加载失败，并给出包含方言／pattern／事件的稳定诊断，不会注册任何钩子监听器。运行时匹配仍会将无效正则隔离为不匹配，因此直接调用本库绝不向 agent loop（智能体循环）抛异常。
 - **执行** — `runHook(bash, hook, options)`。通过 `ctx.bash` seam 而非自建 `spawn` 运行命令钩子：执行器已提供清洗但可覆盖的 env、进程组 kill 和超时，正是协议所需的能力；`dsh-bash` 的 `stdin`/`env` 字段（正是为此添加的）是进程内桥接插件被允许使用的受信插件接口。它将桥接插件构建的 payload 序列化到 stdin（CC 时追加尾部换行），遵守钩子的 `timeoutSec`（否则使用 `DEFAULT_HOOK_TIMEOUT_MS`，即两种方言共享的 10 分钟参考默认值），且从不抛异常（执行器拒绝变为 non-blocking-error 的 `HookOutput`）。
 - **解码** — `parseHookOutput(exit, stdout, stderr)`，exit-code + structured-stdout 编解码器，产出方言无关的 `HookOutput`。Exit `0` → 宽松 JSON 解析 stdout；exit `2` → blocking error，`stderr` 为原因（以 `decision: 'block'` 呈现，调用方无需单独处理 exit-code 分支）；其他 → non-blocking error。解析 CC structured-stdout 中在某条路径上有消费方的字段（`continue`/`stopReason`/`decision`/`hookSpecificOutput.{permissionDecision,additionalContext,updatedInput}`/`systemMessage`）；桥接插件只采纳对其方言有意义的子集。在任何路径上都没有消费方的字段不予解析（CC 的 `suppressOutput`——钩子 stdout 在此处从不进入 transcript（文本记录），因此无需抑制；见 [收紧钩子协议契约 Agent Note](../simplification/2026-07-04-tighten-hook-protocol-contract.md)）。
 - **合并** — `mergeHookOutputs(outputs)`，将多个匹配钩子的输出折叠为一个最严格的 `MergedHookOutcome`：权限优先级 **deny > ask > allow**，halt 在首个 `continue:false` 时粘滞，阻止原因以 `\n\n` 拼接，context/system-messages 按序累积。

 ## Primitives
 
-- **`compileMatchers(matchers, mode)` / `matcherDiagnostic(matcher, mode)` / `matchesMatcher(matcher, query, mode)`** — match-all on absent/`''`/`'*'`; both dialects treat a pure `[A-Za-z0-9_|]+` pattern as exact pipe-separated alternatives. Other patterns are unanchored regexes compiled in the native dialect: JavaScript for Claude Code, Rust `regex` for Codex (including inline flags such as `(?i)`). A bridge parser first discards matcher fields for events without matcher subjects and collects the remaining runnable groups, then compiles their unique patterns once. It reads `registry.diagnostic(pattern)` from those exact instances, disposes the config registry before throwing on a rejected pattern, or returns that registry for runtime matching and teardown after detached runs drain. Codex's valid instances and invalid diagnostics are interned on the synchronous `rregex` dependency module, so they survive hook-protocol/Cordis reloads without using `globalThis`; one-shot helpers share the same interner. Because `rregex` cannot shrink its WASM allocation after `free()`, the process deliberately retains at most `MAX_INTERNED_CODEX_REGEX_PATTERNS` (128) distinct non-literal patterns. Once full, a new distinct pattern is rejected with a capacity diagnostic before calling WASM; previously interned patterns continue to work, and a process restart resets the budget. This is bounded for both same-pattern and adversarial unique reloads without an unbounded cache.
+- **`matcherDiagnostic(matcher, mode)` / `matchesMatcher(matcher, query, mode)`** — match-all on absent/`''`/`'*'`; `claude` mode treats a pure `[A-Za-z0-9_|]+` pattern as a literal (pipe = exact-match alternation) and anything else as a regex; `codex` mode is always an unanchored regex. Bridge parsers discard matcher fields for events without matcher subjects, then use `matcherDiagnostic` to reject an invalid consumed regex with a stable diagnostic before registering any hooks. The runtime predicate still contains an invalid pattern as a non-match, so a direct library caller cannot throw into the agent loop.
 - **`runHook(bash, hook, options, now)`** — require and forward the caller-owned `options.signal`, serialize `options.payload` to the hook's stdin (with a trailing newline iff `options.trailingNewline`), merge `options.env` after the executor's credential scrub (the `dsh-bash` trusted-plugin surface), honor the hook's `timeoutSec` (else `options.defaultTimeoutMs` — the bridge owns the default, its config defaulting to the lib's `DEFAULT_HOOK_TIMEOUT_MS` 10-minute reference), and decode the result (threading `options.expectedEventName` to the codec). Cancellation therefore reaches the executor's process-group kill and join boundary. Never throws: an executor rejection (infra fault) becomes a `HookOutput` with `exitCode: undefined` (a non-blocking error). `now` is injected for testable durations.
 - **`parseHookOutput(exitCode, stdout, stderr, expectedEventName?)`** decodes exit status and structured stdout. Exit 2 blocks with stderr; other failures are non-blocking. A matching hook-specific permission decision overrides the legacy top-level decision; mismatched or missing event discriminators suppress only event-specific fields. Top-level fields remain event-agnostic, and successful non-JSON output is left to the bridge.
 - **`mergeHookOutputs(outputs)`** — fold the results of every hook that matched one point: permission precedence **deny > ask > allow**, halt sticky on the first `continue:false`, block reasons joined with `\n\n`, `additionalContext`/`systemMessages` accumulated in order.

 - **`runHook(bash, hook, options, now)`**：要求并转发调用方拥有的 `options.signal`，将 `options.payload` 序列化到 hook stdin（当且仅当 `options.trailingNewline` 时添加尾随换行符），在执行器凭证清理后合并 `options.env`（`dsh-bash` 受信任插件接口），遵循 hook 的 `timeoutSec`（否则使用 `options.defaultTimeoutMs`；默认值属于桥接，其配置默认为 lib 的 `DEFAULT_HOOK_TIMEOUT_MS` 10 分钟参考值），再解码结果（将 `options.expectedEventName` 传递给 codec）。因此取消会到达执行器的进程组终止与 join 边界。它绝不抛出异常：执行器拒绝（基础设施故障）会变为 `HookOutput`，其 `exitCode: undefined`（非阻塞错误）。`now` 会被注入，以便测试持续时间。
 - **`parseHookOutput(exitCode, stdout, stderr, expectedEventName?)`** 解码退出状态与结构化 stdout。退出码为 2 时，会以 stderr 内容阻止执行；其他失败不阻塞。匹配的 hook 特定权限决策会覆盖遗留顶层决策；事件判别字段不匹配或缺失只会抑制事件特定字段。顶层字段仍与事件无关，成功但非 JSON 的输出会留给桥接处理。
 - **`mergeHookOutputs(outputs)`**：折叠在一个点上匹配的每个 hook 结果：权限优先级为 **deny > ask > allow**，从首个 `continue:false` 起，halt 状态保持不变，阻塞原因用 `\n\n` 连接，`additionalContext`／`systemMessages` 按顺序累积。

+Each wheel contains exactly one runtime executable. The macOS wheel also contains its matching native spawn helper; a missing sidecar makes that installation incomplete and is a hard startup error, even for a selected Cordis composition that does not use PTY tools.

 ## Resolution API
 
 - `resolve_bundled_launch_args(mode=None) -> tuple[str, ...]` — the argv tuple that launches the bundled runtime: `(exe_path,)` in exe mode, `(node_path, bin_js_path)` in node mode. Mode selection: explicit argument > `DSH_RUNTIME_MODE` env var (`exe` | `node`) > automatic. Automatic resolution finds the production exe ONLY — the dev-only node carrier must be opted into explicitly so a production deployment can never silently ride on a source build.
-- `bundled_runtime_path() -> Path` — the platform exe path (exe carrier only; it validates that the required sibling `-spawn-helper` is also installed). The node carrier has no single-path equivalent and launches via the argv tuple above.

 - `bundled_package_dir() -> Path` — the installed package data root.

@@ -19,7 +19,7 @@ Placement and policy rulings folded into this decision:
 - **Not the `ctx.fs` seam.** `packages/fs/` is the model/session-facing storage stack (policy events, sandbox-swappable backends). Riding it would couple GUI browsing to the model's confinement backend — swapping `fs-sandbox` for the model must never change GUI behavior — and OS facts (home anchoring, hidden conventions) are not storage primitives. The picker seam stays presentation-free and model-free; `packages/host/` is its consumer-domain home.
 - **Dependency survey (hand-roll vs adopt).** Node's stdlib *is* the maintained cross-platform OS layer (`readdir(withFileTypes)`, `homedir`, path semantics); surveyed alternatives fail the dependency bar — file-manager packages (`node-file-manager`, `files-and-folders`, Syncfusion's provider) are whole HTTP apps (fit), drive-letter helpers (`drivelist` native addon, `windows-drive-letters` ~7y stale) fail health/proportionality. The browse backend is a thin adapter over stdlib.
 - **Hidden entries: return-and-flag.** The host stamps `hidden` (POSIX dot convention) and returns everything; the client filters. Display policy stays client-side, and the show-hidden toggle shipped as exactly that client-only change: a fixed-label footer toggle whose state lives in the pressed presentation (`aria-pressed` + check glyph), a dot-led path-draft prefix reveals the hidden entries it names, and the current selection is exempt from both the hidden and the prefix filter (it anchors the two-pane view). Windows' `FILE_ATTRIBUTE_HIDDEN` is not exposed by dirents — documented limitation until a native probe pays for itself.
-- **Path-editor cancel scope: the dialog card.** The browse client's path editor cancels on Escape and on focus leaving the card, both observed at a card-scope wrapper rather than the input — after Tab parks focus on a filtered row the input is off the event path, yet Escape must collapse the editor (not the dialog) and a later focus departure must still cancel. Non-cancel exemptions: window/tab focus loss, in-card focus moves, and pointer paths (rows and the toggle suppress focus steal on mousedown while editing). Separators for seeding and draft-tail filtering are inferred from `listing.home`; the wire-field alternative below records the deferred authoritative form. Combobox semantics between the editor and the list it filters (`aria-expanded`/`aria-controls`/active-descendant, result announcements) are likewise deferred — today they read to assistive tech as separate widgets. Focus parking is a card-wide invariant, not an editor-only one: every pick — editing or not, including right-pane advances and create landings whose columns are replaced — re-parks focus on the selection's row after commit, while Enter, an input-focused Escape, and a pick whose row vanished park on the crumb edit zone; keyboard traversal never falls out of the card (the Modal has no focus trap).

Focus parking is a card-wide invariant, not an editor-only one: every pick — editing or not, including right-pane advances and create landings whose columns are replaced — re-parks focus on the selection's row after commit, while every other displacing exit (Enter, Escape, a navigation landing whose new level dropped the focused row, a failed pick or create relist, and the nested create dialog closing) falls back to the crumb edit zone whenever focus actually fell to body; keyboard traversal never falls out of the card (the Modal has no focus trap).
 - **Navigation lands selection-anchored, progressively.** Away from the display root (the same collapse the crumb header renders, so crumbs and pane shape never disagree), the browse client's navigate commits the target level the moment it arrives — the editor closes and loading ends on that first settlement, so an Enter-submitted navigation is never withdrawn waiting on more — and a parent leg then upgrades the landing in place: the target's actual parent-level entry re-selected (platform case folding on Windows), its children on the right, so a crumb jump reads as stepping back one pane rather than collapsing to a single column. The parent leg runs under the landing's supersession scope and is aborted on the wire by any newer intent; a failed parent leg, or a truncated parent window lacking the target, leaves the committed single-pane landing — the upgrade must never orphan the selection it exists to anchor. Known boundaries of the progressive shape: a pointer press landing exactly inside the one-RTT upgrade window can lose its click when the pressed row node is replaced (keyboard focus is re-parked on the re-selected row; the pointer window is accepted); on slash platforms (macOS) only a final-segment case drift misses the parent-entry match and keeps the single-pane landing, while ancestor-segment drift still matches — parent entry paths inherit the typed prefix — and lands two panes at the cost of the Home collapse; and navigate always relists both legs even when the target is the currently shown level — a crumb tap doubles as the refresh gesture, so freshness wins over reusing possibly-stale in-hand listings at the cost of up to two host scans.
 - **Symlinks: follow for enterability.** `stat` probes symlinks (broken/cyclic → skipped); crumbs keep the logical path the operator navigated, and `workspace.create` already canonicalizes via realpath at adoption.
 - **Listing levels are bounded, and streamed.** One `list` call returns at most `maxEntries` rows (config, default 1000 — GitHub's web-UI directory-listing bound). The level streams via `opendir` into a name-sorted window of `maxEntries + 1` candidates, so memory stays O(maxEntries) and enterability probing touches only windowed candidates; the wire `DirectoryListing` carries a required `truncated` flag so the client states incompleteness instead of silently missing tail entries. A windowed broken symlink is not backfilled from beyond the window — the eviction already marks the level truncated. Window insertion is binary with an O(1) full-window tail rejection (an oversized level must not pay a window scan per dirent), and `list(path, signal)` threads the carrier's request signal so a scan of a stalled network directory cannot outlive a disconnected caller — every await in the scan (open, each read, each symlink probe) races the signal, an aborted exit abandons rather than awaits the close (Node queues close behind in-flight reads), and abandoned settlements are swallowed so cleanup can never surface as an unhandled rejection. An unbounded level is a memory/responsiveness hole for large or adversarial directories.

@@ -19,7 +19,7 @@ web GUI 的"打开本地文件夹"流程被焊死在一种交互上：`host.pick
 - **不用 `ctx.fs` seam。** `packages/fs/` 是面向模型／会话的存储栈（policy 事件、sandbox 可换后端）。骑上去会把 GUI 浏览耦合进模型的限制后端——为模型换 `fs-sandbox` 绝不能改变 GUI 行为——而 OS 事实（home 锚定、隐藏约定）也不是存储原语。picker seam 保持无展示、无模型；`packages/host/` 是它消费方域的家。
 - **依赖调研（手写 vs 引入）。** Node 标准库本身就是维护中的跨平台 OS 层（`readdir(withFileTypes)`、`homedir`、路径语义）；调研过的替代品都过不了依赖门槛——文件管理器包（`node-file-manager`、`files-and-folders`、Syncfusion 的 provider）是整套 HTTP 应用（契合度不过），盘符工具（原生插件 `drivelist`、约七年未更的 `windows-drive-letters`）健康度／比例失当。browse 后端是标准库上的薄适配。
 - **隐藏条目：返回并打标。** 宿主标注 `hidden`（POSIX 点前缀约定）并返回全部条目；客户端过滤。展示策略留在客户端，"显示隐藏"开关正是作为这一纯客户端改动落地：标签固定的 footer 开关，其状态由按下态呈现承载（`aria-pressed` + 勾选符号）；以点开头的路径草稿前缀会显出它所指名的隐藏条目；当前选中项则不受隐藏与前缀两种过滤影响（它锚定着双栏视图）。Windows 的 `FILE_ATTRIBUTE_HIDDEN` 不被 dirent 暴露——记为限制，直到原生探测值回其成本。
-- **路径编辑器的取消范围：对话框卡片。** browse 客户端的路径编辑器在按 Escape 与焦点离开卡片时取消，两者都在卡片范围的包装层而非输入框上监听——Tab 把焦点停到某个过滤命中的行之后，输入框已不在事件路径上，但 Escape 仍须收起编辑器（而非对话框），其后的焦点离开也仍须取消。不取消的豁免：窗口／标签页失焦、卡片内焦点移动，以及指针路径（编辑期间行与开关在 mousedown 时抑制焦点夺取）。预填与草稿末段过滤所用的分隔符从 `listing.home` 推断；下文的线上字段替代方案记录了被延期的权威形态。编辑器与其过滤的列表之间的 combobox 语义（`aria-expanded`／`aria-controls`／active-descendant、结果播报）同样被延期——目前二者在辅助技术看来是彼此独立的控件。焦点停靠是卡片全域的不变量，而非编辑器独有：每次选取——无论是否处于编辑态，包括右栏推进与各列被替换的创建落地——提交后都把焦点重新停靠到选中项所在的行上，而 Enter、焦点在输入框上时的 Escape，以及所在行已消失的选取则停靠到 crumb 编辑区；键盘遍历绝不会落出卡片之外（Modal 没有焦点陷阱）。

 - **导航以选中项为锚、渐进落地。** 在展示根之外（与 crumb 头部渲染的是同一塌缩，因此 crumb 与分栏形态永不相左），browse 客户端的导航在目标层级到达的那一刻即提交它——这次首个落定即关闭编辑器并结束加载，因此 Enter 提交的导航绝不会为等待更多内容而被撤回——随后父层级这一程就地升级这次落地：重新选中目标在父层级中的实际条目（Windows 上按平台惯例折叠大小写），右侧展示其子项，因此 crumb 跳转读作后退一栏，而不是塌缩成单列。父层级这一程在落地的 supersession 范围下运行，任何较新的意图都会在线上将其中止；父层级这一程失败，或被截断的父窗口缺少目标时，都保留已提交的单栏落地——升级的存在正是为了锚定选中项，绝不能反而让它悬空。渐进形态的已知边界：指针按压若恰好落在单个 RTT 的升级窗口内，可能因所按行节点被替换而丢失点击（键盘焦点会重新停靠到重新选中的行上；指针的这段窗口则被接受）；斜杠平台（macOS）上仅末段的大小写偏差会错过父层级条目匹配，保留单栏落地，而祖先段的偏差仍能匹配——父层级条目路径继承键入的前缀——并落地双栏，代价是 Home 塌缩；且导航总是重新列举两程，哪怕目标就是当前展示的层级——crumb 点按兼作刷新手势，因此宁要新鲜度也不复用手头可能已陈旧的列举，代价是至多两次宿主扫描。
 - **符号链接：为可进入性而跟随。** 用 `stat` 探测符号链接（断链／循环→跳过）；面包屑保留操作者导航的逻辑路径，`workspace.create` 在接纳时本就做 realpath 规范化。
 - **列举层级有上限，且流式处理。** 单次 `list` 至多返回 `maxEntries` 行（配置项，默认 1000——GitHub 网页端目录列举的同一上限）。层级经 `opendir` 流入一个按名排序、容量 `maxEntries + 1` 的候选窗口，内存保持 O(maxEntries)，可进入性探测只触及窗口内候选；线上 `DirectoryListing` 携带必填的 `truncated` 标志，让客户端明示不完整而不是静默缺尾。窗口内的断链符号链接不从窗口外回填——发生过驱逐本身已把层级标记为截断。窗口插入为二分查找、满窗尾部单次比较即拒绝（超大层级不能为每个 dirent 付出一次全窗扫描），且 `list(path, signal)` 透传载体的请求信号，滞塞网络目录的扫描不会在调用方断连后继续存活——扫描中的每个 await（打开、每次读取、每次符号链接探测）都与信号赛跑，中止路径放弃而非等待 close（Node 会把 close 排在在飞读取之后），被放弃的 settlement 全部吞掉，清理不会以未处理拒绝的形式冒出。无上限的层级对超大或恶意构造的目录就是内存／响应性漏洞。

 `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:<name>`. 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 <id>` of the session is an ordinary TUI session with no re-injection.
 
 
-The Web and headless surfaces boot `base.cordis.yml` plus `web.cordis.yml`; `dsh web --config <path>` adds an overlay after the web surface defaults. 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 <path>` overrides it, load applicable `AGENTS.md`/`CLAUDE.md` instructions into each agent-loop request prefix with a 65,536-byte render budget, and opt into first-message model titles. 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).

@@ -19,7 +19,7 @@ Placement and policy rulings folded into this decision:
 - **Not the `ctx.fs` seam.** `packages/fs/` is the model/session-facing storage stack (policy events, sandbox-swappable backends). Riding it would couple GUI browsing to the model's confinement backend — swapping `fs-sandbox` for the model must never change GUI behavior — and OS facts (home anchoring, hidden conventions) are not storage primitives. The picker seam stays presentation-free and model-free; `packages/host/` is its consumer-domain home.
 - **Dependency survey (hand-roll vs adopt).** Node's stdlib *is* the maintained cross-platform OS layer (`readdir(withFileTypes)`, `homedir`, path semantics); surveyed alternatives fail the dependency bar — file-manager packages (`node-file-manager`, `files-and-folders`, Syncfusion's provider) are whole HTTP apps (fit), drive-letter helpers (`drivelist` native addon, `windows-drive-letters` ~7y stale) fail health/proportionality. The browse backend is a thin adapter over stdlib.
 - **Hidden entries: return-and-flag.** The host stamps `hidden` (POSIX dot convention) and returns everything; the client filters. Display policy stays client-side, and the show-hidden toggle shipped as exactly that client-only change: a fixed-label footer toggle whose state lives in the pressed presentation (`aria-pressed` + check glyph), a dot-led path-draft prefix reveals the hidden entries it names, and the current selection is exempt from both the hidden and the prefix filter (it anchors the two-pane view). Windows' `FILE_ATTRIBUTE_HIDDEN` is not exposed by dirents — documented limitation until a native probe pays for itself.
-- **Path-editor cancel scope: the dialog card.** The browse client's path editor cancels on Escape and on focus leaving the card, both observed at a card-scope wrapper rather than the input — after Tab parks focus on a filtered row the input is off the event path, yet Escape must collapse the editor (not the dialog) and a later focus departure must still cancel. Non-cancel exemptions: window/tab focus loss, in-card focus moves, and pointer paths (rows and the toggle suppress focus steal on mousedown while editing). Separators for seeding and draft-tail filtering are inferred from `listing.home`; the wire-field alternative below records the deferred authoritative form. Combobox semantics between the editor and the list it filters (`aria-expanded`/`aria-controls`/active-descendant, result announcements) are likewise deferred — today they read to assistive tech as separate widgets. Focus parking is a card-wide invariant, not an editor-only one: every pick — editing or not, including right-pane advances and create landings whose columns are replaced — re-parks focus on the selection's row after commit, while every other displacing exit (Enter, Escape, a navigation landing whose new level dropped the focused row, a failed pick or create relist, and the nested create dialog closing) falls back to the crumb edit zone whenever focus actually fell to body; keyboard traversal never falls out of the card (the Modal has no focus trap).

 - **Navigation lands selection-anchored, progressively.** Away from the display root (the same collapse the crumb header renders, so crumbs and pane shape never disagree), the browse client's navigate commits the target level the moment it arrives — the editor closes and loading ends on that first settlement, so an Enter-submitted navigation is never withdrawn waiting on more — and a parent leg then upgrades the landing in place: the target's actual parent-level entry re-selected (platform case folding on Windows), its children on the right, so a crumb jump reads as stepping back one pane rather than collapsing to a single column. The parent leg runs under the landing's supersession scope and is aborted on the wire by any newer intent; a failed parent leg, or a truncated parent window lacking the target, leaves the committed single-pane landing — the upgrade must never orphan the selection it exists to anchor. Known boundaries of the progressive shape: a pointer press landing exactly inside the one-RTT upgrade window can lose its click when the pressed row node is replaced (keyboard focus is re-parked on the re-selected row; the pointer window is accepted); on slash platforms (macOS) only a final-segment case drift misses the parent-entry match and keeps the single-pane landing, while ancestor-segment drift still matches — parent entry paths inherit the typed prefix — and lands two panes at the cost of the Home collapse; and navigate always relists both legs even when the target is the currently shown level — a crumb tap doubles as the refresh gesture, so freshness wins over reusing possibly-stale in-hand listings at the cost of up to two host scans.
 - **Symlinks: follow for enterability.** `stat` probes symlinks (broken/cyclic → skipped); crumbs keep the logical path the operator navigated, and `workspace.create` already canonicalizes via realpath at adoption.
 - **Listing levels are bounded, and streamed.** One `list` call returns at most `maxEntries` rows (config, default 1000 — GitHub's web-UI directory-listing bound). The level streams via `opendir` into a name-sorted window of `maxEntries + 1` candidates, so memory stays O(maxEntries) and enterability probing touches only windowed candidates; the wire `DirectoryListing` carries a required `truncated` flag so the client states incompleteness instead of silently missing tail entries. A windowed broken symlink is not backfilled from beyond the window — the eviction already marks the level truncated. Window insertion is binary with an O(1) full-window tail rejection (an oversized level must not pay a window scan per dirent), and `list(path, signal)` threads the carrier's request signal so a scan of a stalled network directory cannot outlive a disconnected caller — every await in the scan (open, each read, each symlink probe) races the signal, an aborted exit abandons rather than awaits the close (Node queues close behind in-flight reads), and abandoned settlements are swallowed so cleanup can never surface as an unhandled rejection. An unbounded level is a memory/responsiveness hole for large or adversarial directories.

 - **不用 `ctx.fs` seam。** `packages/fs/` 是面向模型／会话的存储栈（policy 事件、sandbox 可换后端）。骑上去会把 GUI 浏览耦合进模型的限制后端——为模型换 `fs-sandbox` 绝不能改变 GUI 行为——而 OS 事实（home 锚定、隐藏约定）也不是存储原语。picker seam 保持无展示、无模型；`packages/host/` 是它消费方域的家。
 - **依赖调研（手写 vs 引入）。** Node 标准库本身就是维护中的跨平台 OS 层（`readdir(withFileTypes)`、`homedir`、路径语义）；调研过的替代品都过不了依赖门槛——文件管理器包（`node-file-manager`、`files-and-folders`、Syncfusion 的 provider）是整套 HTTP 应用（契合度不过），盘符工具（原生插件 `drivelist`、约七年未更的 `windows-drive-letters`）健康度／比例失当。browse 后端是标准库上的薄适配。
 - **隐藏条目：返回并打标。** 宿主标注 `hidden`（POSIX 点前缀约定）并返回全部条目；客户端过滤。展示策略留在客户端，"显示隐藏"开关正是作为这一纯客户端改动落地：标签固定的 footer 开关，其状态由按下态呈现承载（`aria-pressed` + 勾选符号）；以点开头的路径草稿前缀会显出它所指名的隐藏条目；当前选中项则不受隐藏与前缀两种过滤影响（它锚定着双栏视图）。Windows 的 `FILE_ATTRIBUTE_HIDDEN` 不被 dirent 暴露——记为限制，直到原生探测值回其成本。
-- **路径编辑器的取消范围：对话框卡片。** browse 客户端的路径编辑器在按 Escape 与焦点离开卡片时取消，两者都在卡片范围的包装层而非输入框上监听——Tab 把焦点停到某个过滤命中的行之后，输入框已不在事件路径上，但 Escape 仍须收起编辑器（而非对话框），其后的焦点离开也仍须取消。不取消的豁免：窗口／标签页失焦、卡片内焦点移动，以及指针路径（编辑期间行与开关在 mousedown 时抑制焦点夺取）。预填与草稿末段过滤所用的分隔符从 `listing.home` 推断；下文的线上字段替代方案记录了被延期的权威形态。编辑器与其过滤的列表之间的 combobox 语义（`aria-expanded`／`aria-controls`／active-descendant、结果播报）同样被延期——目前二者在辅助技术看来是彼此独立的控件。焦点停靠是卡片全域的不变量，而非编辑器独有：每次选取——无论是否处于编辑态，包括右栏推进与各列被替换的创建落地——提交后都把焦点重新停靠到选中项所在的行上，而其余所有会顶离焦点的退出（Enter、Escape、新层级已不含焦点所在行的导航落地、选取或创建失败后的重新列举，以及嵌套创建对话框的关闭）只要焦点确实落到了 body 上，就回落到 crumb 编辑区；键盘遍历绝不会落出卡片之外（Modal 没有焦点陷阱）。

 - **导航以选中项为锚、渐进落地。** 在展示根之外（与 crumb 头部渲染的是同一塌缩，因此 crumb 与分栏形态永不相左），browse 客户端的导航在目标层级到达的那一刻即提交它——这次首个落定即关闭编辑器并结束加载，因此 Enter 提交的导航绝不会为等待更多内容而被撤回——随后父层级这一程就地升级这次落地：重新选中目标在父层级中的实际条目（Windows 上按平台惯例折叠大小写），右侧展示其子项，因此 crumb 跳转读作后退一栏，而不是塌缩成单列。父层级这一程在落地的 supersession 范围下运行，任何较新的意图都会在线上将其中止；父层级这一程失败，或被截断的父窗口缺少目标时，都保留已提交的单栏落地——升级的存在正是为了锚定选中项，绝不能反而让它悬空。渐进形态的已知边界：指针按压若恰好落在单个 RTT 的升级窗口内，可能因所按行节点被替换而丢失点击（键盘焦点会重新停靠到重新选中的行上；指针的这段窗口则被接受）；斜杠平台（macOS）上仅末段的大小写偏差会错过父层级条目匹配，保留单栏落地，而祖先段的偏差仍能匹配——父层级条目路径继承键入的前缀——并落地双栏，代价是 Home 塌缩；且导航总是重新列举两程，哪怕目标就是当前展示的层级——crumb 点按兼作刷新手势，因此宁要新鲜度也不复用手头可能已陈旧的列举，代价是至多两次宿主扫描。
 - **符号链接：为可进入性而跟随。** 用 `stat` 探测符号链接（断链／循环→跳过）；面包屑保留操作者导航的逻辑路径，`workspace.create` 在接纳时本就做 realpath 规范化。
 - **列举层级有上限，且流式处理。** 单次 `list` 至多返回 `maxEntries` 行（配置项，默认 1000——GitHub 网页端目录列举的同一上限）。层级经 `opendir` 流入一个按名排序、容量 `maxEntries + 1` 的候选窗口，内存保持 O(maxEntries)，可进入性探测只触及窗口内候选；线上 `DirectoryListing` 携带必填的 `truncated` 标志，让客户端明示不完整而不是静默缺尾。窗口内的断链符号链接不从窗口外回填——发生过驱逐本身已把层级标记为截断。窗口插入为二分查找、满窗尾部单次比较即拒绝（超大层级不能为每个 dirent 付出一次全窗扫描），且 `list(path, signal)` 透传载体的请求信号，滞塞网络目录的扫描不会在调用方断连后继续存活——扫描中的每个 await（打开、每次读取、每次符号链接探测）都与信号赛跑，中止路径放弃而非等待 close（Node 会把 close 排在在飞读取之后），被放弃的 settlement 全部吞掉，清理不会以未处理拒绝的形式冒出。无上限的层级对超大或恶意构造的目录就是内存／响应性漏洞。

+**User bubbles prepend a date-aware local clock to the existing IconActions row; finalized assistant *content* nodes (non-empty text blocks) append a copy / branch / clock row with `margin-top: 16px`; both seats stay visible whenever mounted and re-format at the next local midnight.**
 
-Both seats format `node.time` through `formatMessageClock`: same calendar day → `HH:mm`, earlier this year → `M月D日 HH:mm`, other years → `YYYY年M月D日 HH:mm`. `useCalendarDay` is a component-local day tick (timeout to the next local midnight) so memoized rows re-render when the calendar day changes without a new framework hook. `MessageItem` places the label before copy (figma `388:20051`). `AssistantMarkdown` places it after branch (figma `43:32997`) and only when `streaming` is false with a known event time; the streaming tail omits the row. Copy writes joined text blocks. Branch stays a chrome stub. Hover-capable pointers keep both footers opacity-hidden until hover/focus-within. Clipboard write and the clock helpers live in `message-chrome.ts`. The assembled surface is pinned by `apps/web/tests/message-actions.e2e.ts` (cold-seeded history + aria golden); aria normalization collapses every clock shape to `{{clock}}`.

 ## Alternatives considered
 
 **Show assistant IconActions during streaming.** Rejected: the request is to reveal the row only after output completes; mid-stream chrome would flicker and invite copying a partial answer.
 
+**Put IconActions under every finalized assistant node (including Think-only).** Rejected: copy has nothing useful to write without text content, and repeating the chrome under every step/Think row clutters the flow; only content output owns the seat.
+
+**Hover-reveal the action row on hover-capable pointers.** Rejected: once the row exists it should stay discoverable; opacity hiding made the chrome easy to miss and required parent hover selectors that duplicated the mount gate.
+
 **Wire branch to a real session fork.** Rejected for this change: same rationale as the archived [user IconActions note](../../archived/feature/2026-07-27-user-message-icon-actions.md) — the mutation path is unspecified; the button reserves the design seat.
 
 **Publish the calendar day through a chat store or inject hook.** Rejected: the day tick is presentation-only local state with no cross-entry consumers; a component-local timeout matches the client rule that behavioral hooks may own state that does not subscribe to an external source.
 
 ## Consequences
 
-Settled assistant answers expose copy and the event clock immediately; branch stays a stub. User and assistant clocks share the same day/year widening rules and refresh after midnight without a message mutation. Per-message paging remains a deferred footer seat in the package README. Package tests pin the three clock shapes and the midnight widen; the web e2e scenario pins the assembled IconActions chrome.

 ## 曾考虑的方案
 
 **在流式过程中展示 assistant IconActions。** 否决：需求是输出完成后才展示该行；中途 chrome 会闪烁，并诱使复制半截回答。
 
+**给每个已定稿 assistant 节点（含纯 Think）都挂 IconActions。** 否决：没有 text 内容时复制没有可写内容，且在每一步／Think 下重复 chrome 会打乱流程；只有内容输出拥有该座位。
+
+**在具备 hover 能力的指针上用 hover 才揭示操作行。** 否决：行一旦存在就应保持可发现；用 opacity 隐藏容易漏看，且需要父级 hover 选择器重复挂载门控。
+
 **把分支接到真实的会话 fork。** 本次否决：与已归档的[用户 IconActions 笔记](../../archived/feature/2026-07-27-user-message-icon-actions.md)同一理由——变更路径尚未规定；按钮只预留设计座位。
 
 **通过 chat store 或 inject hook 发布日历日。** 否决：日刻度只是展示层本地状态，没有跨入口消费者；组件本地 timeout 符合「行为 hook 可拥有不订阅外部源的状态」这一客户端规则。
 
 ## 后果
 
-已定稿的 assistant 回答立刻暴露复制与事件时钟；分支仍为 stub。用户与 assistant 时钟共用同一套跨天／跨年加宽规则，并在午夜后无需消息变更即可刷新。逐消息分页仍是包 README 中的暂缓 footer 座位。包级测试钉住三种时钟形态与午夜加宽；Web e2e 场景钉住组装后的 IconActions chrome。

If admission blocks or fails, a context-only caller batch takes idle injection's immediate append, while steering and context staged beside it remain available to retry; neither path writes the rejected prompt. When a later prompt is admitted, retained outbox input enters its turn before that prompt, while input accepted during the current admission remains after the prompt. Closing the window before `turn/end` preserves the rule that reentrant late steering becomes an independent queued turn. `Agent.acceptsNextStep` exposes whether a `next-step` send would currently join this window; `status` remains the broader activity signal rather than a routing predicate.

 The delivery surface is now one primitive plus three self-documenting presets, and the (`target` × `wakeup`) matrix makes previously-unreachable combinations explicit. One durable message type serves prompts, injected context, and goal rounds, so the surface projection and every "human prompt?" check simplify to a `source` test. The `Agent` contract remains an interface, so alternate implementations and object-literal test fakes implement the same minimal structural surface. The goal fold's channel split moved from event type to `source.round`, and every consumer that filtered `context/message` now filters `user/message` by source. An idle injection appends `user/message` between turns without opening a turn or running the model.

Every FIFO exit publishes exactly one lifecycle event, while domain-specific durable facts travel in typed message sources rather than a parallel metadata channel.

+# Agent Note: Address pending queue occurrences for edit, remove, and promotion
+
+Status: implemented
+
+English | [中文](2026-07-29-addressable-queue-operations.zh.md)
+
+## Problem
+
+The Web queue rendered pending messages but could not act on one row. `MessageId` was insufficient as an address because callers may enqueue the same immutable message more than once. The browser also inferred queue retirement from turn and status events, so a row operation racing with driver claim had no authoritative outcome.
+
+“Send now” introduced a separate semantic choice: it could mean reorder the next independent turn, interrupt the current turn as steering, or cancel current work. Only the first interpretation preserves the queue row’s original delivery contract.
+
+## Decision
+
+**Each accepted FIFO occurrence has its own identity.** AgentLoop mints an opaque `InboxItemId` and publishes an `InboxItem` containing that id, the identified `UserMessage`, and its acceptance-time `queued | steering` placement. Reusing one `MessageId` creates distinct inbox identities. Injection bypasses the FIFOs and receives no inbox identity.
+
+**Mutation ends at driver claim.** `Agent.updateInbox(id, action)` synchronously searches the pending queued and steering FIFOs. Edit replaces frozen content while preserving `InboxItemId`, `MessageId`, source, placement, wake policy, and position. Remove emits the occurrence’s terminal discard. Promote moves it to the front of its current FIFO; an ordinary queued item also becomes waking. The driver removes an occurrence before prompt admission or steering drain, so a later mutation returns `not-found` and never rewrites durable history.
+
+**The live ledger is authoritative.** `agent/inbox/enqueue`, `update`, `dequeue`, and `discard` maintain a Host mirror. The wire sends complete `session/queue` snapshots rather than incremental guesses. Reconnect sends the current baseline, and every live mutation or terminal event replaces it. The client applies no optimistic edit and never retires a row from `turn/start`, `steering/message`, or status changes.
+
+**Web actions preserve delivery kind.** QueueDock projects only `queued` occurrences; pending `steering` occurrences remain in the authoritative snapshot but wait for a dedicated Web interaction. It exposes edit and delete, but no send-now control. Edit is available only when all content blocks are text; the editor cannot silently drop non-text blocks. An editing row exposes only save and cancel, with Enter and Escape as their keyboard equivalents. Delete removes the exact occurrence. Protocol-level promotion remains available without being presented as a Web interaction; it never converts queued work into steering or cancels active work.
+
+## Alternatives considered
+
+**Address rows by `MessageId`.** Rejected because one immutable message may be sent repeatedly; editing or deleting by message identity would affect an ambiguous occurrence.
+
+**Apply optimistic browser mutations.** Rejected because driver claim and another client can win before the Host action. Waiting for the authoritative snapshot makes the ownership boundary visible and lets `queue-item-not-found` report a real race.
+
+**Treat send-now as steering.** Rejected because it would change a queued independent turn into current-turn context, bypass ordinary prompt admission, and alter the one-send-one-turn guarantee. Promotion changes priority, not delivery semantics.
+
+**Cancel the active turn before promotion.** Rejected because a row-local action must not destroy unrelated in-flight work.
+
+## Verification
+
+AgentLoop contract tests hold prompt admission while editing, removing, and promoting exact occurrences, then verify the resulting independent-turn order and terminal lifecycle events. Host schema and proxy tests cover authoritative snapshots, reconnect, typed not-found errors, and the RPC transport. Client runtime and QueueDock tests cover non-optimistic projection, queued-only Web projection, text-only editing, save and cancel affordances, removal, retirement races, disabled mixed-content editing, and the absent send-now control. Keyless browser scenarios drive the exposed edit and delete actions and keep accepted pending steering hidden until it becomes a durable transcript event through the built Web composition and real HTTP/SSE wire.
+
+## Consequences
+
+Pending work gains precise row operations without becoming durable session history. Occurrence identity is a live process-local capability and disappears at claim, cancellation, disposal, or restart; reconnect recovers only items still held by the live Agent. Send-now is intentionally weaker than interruption, and editing intentionally excludes mixed content until an editor can preserve every block.
+
+The protocol now carries full queue snapshots on each change. Queues are expected to remain short, so deterministic recovery and multi-client convergence are preferred over an incremental mutation protocol.

+# Agent Note（agent 决策记录）：为待处理队列项提供编辑、移除与前移操作
+
+Status: implemented
+
+[English](2026-07-29-addressable-queue-operations.md) | 中文
+
+## 问题
+
+Web 队列能够渲染待处理消息，但无法操作其中某一行。`MessageId` 不足以充当寻址标识，因为调用方可以多次将同一条不可变消息加入队列。浏览器还会根据轮次和状态事件推断队列项已退役，因此当行操作与驱动器认领发生竞态时，系统无法给出权威结果。
+
+“立即发送”还引入了另一项语义选择：它可以表示重新排序下一个独立轮次、以 steering（中途引导）方式打断当前轮次，或取消当前工作。只有第一种解释能够保留该队列行原有的投递契约。
+
+## 决策
+
+**每次获准进入 FIFO 的项都有独立标识。** AgentLoop 会铸造不透明的 `InboxItemId`，并发布一个 `InboxItem`，其中包含该 id、已有标识的 `UserMessage`，以及接受时确定的 `queued | steering` 放置方式。复用同一个 `MessageId` 会创建不同的 inbox 标识。注入绕过 FIFO，因此不会获得 inbox 标识。
+
+**变更边界止于驱动器认领。** `Agent.updateInbox(id, action)` 会同步搜索仍处于待处理状态的 queued 和 steering FIFO。编辑会替换已冻结的内容，同时保留 `InboxItemId`、`MessageId`、来源、放置方式、唤醒策略和位置。移除会发出该次入队项的终态 discard。前移会把它移至当前 FIFO 的队首；普通 queued 项还会变为可唤醒。驱动器会在提示词接纳或排空 steering 之前移除该项，因此之后的变更会返回 `not-found`，绝不会改写持久历史。
+
+**实时账本是权威状态。** `agent/inbox/enqueue`、`update`、`dequeue` 和 `discard` 共同维护 Host 镜像。协议发送完整的 `session/queue` 快照，而非增量猜测。重连会发送当前基线，每次实时变更或终态事件都会整体替换它。客户端不会进行乐观编辑，也绝不根据 `turn/start`、`steering/message` 或状态变化退役队列行。
+
+**Web 操作保持投递类型。** QueueDock 只投影 `queued` 入队项；待处理的 `steering` 入队项仍保留在权威快照中，等待 Web 提供专用交互。它只暴露编辑和删除，不提供立即发送控件。仅当所有内容块都是文本时才提供编辑功能；编辑器不能静默丢弃非文本块。编辑中的行只展示保存和取消操作，对应的键盘操作分别是 Enter 和 Escape。删除会移除对应的精确入队项。协议层仍保留前移操作，但不会把它呈现为 Web 交互；该操作绝不会把 queued 工作转换为 steering，也不会取消活动工作。
+
+## 考虑过的替代方案
+
+**通过 `MessageId` 寻址行。** 不予采纳，因为同一条不可变消息可以重复发送；按消息标识编辑或删除会无法确定应操作哪一次入队。
+
+**在浏览器中进行乐观变更。** 不予采纳，因为驱动器认领或另一个客户端可能先于 Host 操作完成。等待权威快照可以显式呈现所有权边界，并让 `queue-item-not-found` 报告真实竞态。
+
+**把立即发送视为 steering。** 不予采纳，因为这会把一个独立的排队轮次变成当前轮次的上下文，绕过普通提示词接纳，并改变单次 send 单轮次保证。前移只改变优先级，不改变投递语义。
+
+**前移前取消活动轮次。** 不予采纳，因为仅影响某一行的操作不应破坏无关的进行中工作。
+
+## 验证
+
+AgentLoop 契约测试会在编辑、移除和前移对应的精确入队项时阻塞提示词接纳，随后验证所得独立轮次顺序及终态生命周期事件。Host schema 与代理测试覆盖权威快照、重连、类型化 not-found 错误和 RPC 传输。客户端运行时和 QueueDock 测试覆盖非乐观投影、Web 仅投影 queued 项、仅文本编辑、保存与取消入口、移除、退役竞态、禁用混合内容编辑，以及不提供立即发送控件。无密钥浏览器场景会通过构建后的 Web 组合和真实 HTTP／SSE 协议操作公开的编辑和删除，并使已接受的待处理 steering 在成为持久 transcript（文本记录）事件之前保持隐藏。
+
+## 后果
+
+待处理工作获得精确的行操作，但不会因此成为持久会话历史。单次入队标识是进程本地的实时寻址凭据，会在认领、取消、dispose 或重启时消失；重连只能恢复仍由活跃 Agent 持有的项。立即发送有意弱于打断，而编辑也有意排除混合内容，直至编辑器能够保留每个块。
+
+现在，协议会在每次变更时携带完整队列快照。队列预期保持较短，因此系统优先选择确定性恢复和多客户端收敛，而非增量变更协议。

 The rule is simple: each successful `send()` creates one independent FIFO queue item. If that item runs, it is the only ordinary message in its turn. An item can be dropped before it starts, so the precise guarantee is at most one turn rather than exactly one; two sends are never silently combined.

+Before enqueueing an item, `send()` checks the agent state and accepts an already identified, deeply frozen message. It mints an occurrence-local `InboxItemId` and publishes `agent/inbox/enqueue`; the pending occurrence remains addressable under the [addressable queue operations](../feature/2026-07-29-addressable-queue-operations.md) decision until the driver claims or discards it.
 
 If messages A and B are both processed, B's turn starts only after A records `turn/end` and A's durability checkpoint settles. B's request therefore sees whatever closed result A left in the same session log. A checkpoint error is reported, but settlement only releases this ordering barrier; it does not make a failed write durable. Broad `cancel()`, disposal, or a failure before `turn/start` can instead discard an unstarted item without opening an empty turn.

 ## Consequences
 
-Ordinary turn boundaries are predictable: messages A and B stay separate, and B runs only after A has closed and reached its checkpoint. Callers still do not receive a per-send completion or cancellation handle; broad cancellation can discard the entire unstarted tail, while status and quiescence remain agent-wide observations.

Callers still do not receive a per-send completion handle; a pending occurrence can be removed through its live `InboxItemId`, broad cancellation can discard the entire unstarted tail, and status and quiescence remain agent-wide observations.
 
 The trade-off is more model requests and more checkpoints. A busy queue can take longer to drain and can grow under sustained producers. Ordinary-send batching returns only through an explicit, measured contract.

 规则很简单：一次成功的 `send()` 创建一个独立的 FIFO 队列项。该队列项如果运行，就是所在轮次中唯一的普通消息。队列项可能在启动前被丢弃，因此精确保证是最多一个轮次，而不是必定一个轮次；两次 send 绝不会被悄悄合并。

 如果消息 A、B 都进入处理，B 的轮次只能在 A 记录 `turn/end` 且 A 的持久性检查点处理结束后开始。因此，B 的请求能看到 A 在同一会话日志中留下的已关闭结果。检查点错误会照常报告，但处理结束只表示解除这道顺序屏障，不表示失败的写入已经持久化。广义 `cancel()`、dispose（资源释放）或 `turn/start` 之前的失败也可能丢弃尚未启动的队列项，而不打开一个空轮次。

 ## 后果
 
-普通轮次的边界可预测：消息 A、B 始终分开，B 只能在 A 关闭并到达检查点后运行。调用方仍然拿不到逐次 send 的完成或取消句柄；广义取消可以丢弃整个尚未启动的队尾，状态和静止性也仍是面向整个 agent 的观察。

 代价是模型请求和检查点都会增加。繁忙队列可能需要更长时间才能清空；如果生产方持续提交消息，队列也可能增长。只有建立显式且经过测量的契约后，才能重新引入普通 send 批处理。

 `WorkspacesService.connectWorkspace(workspaceId)` resolves the session a New Session flow lands in: it reuses the workspace's existing blank session from the list mirror (`blank && cwd == workspace.path`) or calls `session.create({workspaceId})`, returning the session id for the caller to open. `SessionSummary.blank` mirrors the host's derived empty-log bit and only ever lowers on the client: seeded by `session.list` / the `host/session-added` frame, flipped false by the first ACCEPTED local `prompt()` (on the RPC success response — acceptance proves the user message is in the host log; a rejected first prompt keeps the session blank and reusable) and by any `running: true` status frame, re-aligned by every list re-pull. List surfaces hide blank rows; the store carries every row. `SessionsService.create` accepts an optional caller-preallocated SessionId and throws `SessionCreateError` (carrying `requestedSessionId`) on failure.
 
+## Pending queue projection
+
+`ConversationSnapshot.queue` is the Host's authoritative transient inbox snapshot. Each row carries its `InboxItemId`, complete editable text when every content block is text, a flattened preview, and the accepted queued-or-steering placement. `session/queue` replaces the whole projection; reconnect buffering retains only the latest snapshot, and neither durable turn events nor running-status changes guess that an item was claimed. `Session.updateQueue()` sends edit/remove/promote operations without optimistic mutation, so the next Host snapshot is the sole visible commit and a claim race can surface `queue-item-not-found`.
+
 ## Code Mode sub-dispatch index
 
 `ConversationSnapshot.codeDispatches` groups a `run_code` call's sub-dispatches under their parent callId, in start order, using the native call-block shapes: a `tool/code-dispatch-start` event lands the `RunningToolCall` form (rows derive the running ring from the shape) and its `tool/code-dispatch` settlement replaces it in place with the `ToolResultNode` form, `callTime` carrying the paired start's time. A settle whose start fell outside the replay window appends directly with `callTime: null` (duration unknown — never a fabricated zero). Live mux frames and history replay build the identical index; sub-calls never join the surface `nodes` flow; per-parent array and map references are memo-stable across unrelated snapshot swaps.

+## 待处理队列投影

+`ConversationSnapshot.queue` 是 Host 提供的权威瞬态 inbox 快照。每行都携带其 `InboxItemId`、所有内容块均为文本时的完整可编辑文本、扁平化预览，以及接受时确定的 queued 或 steering 放置方式。`session/queue` 会整体替换该投影；重连缓冲只保留最新快照，持久轮次事件和 running 状态变化都不会猜测某个项已被认领。`Session.updateQueue()` 发送编辑／移除／前移操作，不进行乐观更新，因此下一份 Host 快照是唯一可见的提交结果，认领竞态则会返回 `queue-item-not-found`。
+
 ## Code Mode 子调用索引
 
 `ConversationSnapshot.codeDispatches` 按父调用的 callId 和启动顺序，用原生调用块形状组织一个 `run_code` 调用的子调用：`tool/code-dispatch-start` 事件落成 `RunningToolCall` 形状（行组件从该形状推导运行中的转圈状态），其 `tool/code-dispatch` 完结事件原位替换为 `ToolResultNode` 形状，`callTime` 携带成对 start 事件的时间。start 落在回放窗口之外的完结事件则直接追加，`callTime: null`（耗时未知——绝不伪造零耗时）。live mux 帧与历史回放构建相同的索引；子调用永不进入 surface `nodes` 流；无关快照交换不会改变每个父调用对应的数组引用和映射引用，两者均保持 memo 稳定。

+- **Queue edit is text-only** — rows containing non-text blocks still show a flattened preview, but their edit control is disabled because the inline editor cannot preserve those blocks. A text row's edit mode replaces delete with save and cancel; Enter saves and Escape cancels. QueueDock exposes no send-now control; protocol-level promotion remains separate from the Web interaction.

 The concrete `ReactLoopAgent`, its queued input, outbox, and run controls are package-internal. The package root exports only the plugin/service/config contract, and the package exports map exposes no `./src/*` escape hatch; lifecycle owners create agents through `ctx.agents` rather than naming, constructing, or starting driver internals. One prepared session can be claimed by only one concrete driver, and everything observable happens through session events and the `agent/*` event taxonomy.
 
-The unified `send()` primitive routes content and source by (`target` × `wakeup`); `followup`/`steer`/`inject` are its fixed-preset aliases. A `next-turn` item joins the queued FIFO, waking the driver unless `wakeup: false`; admission happens before any turn opens. The loop opens a private next-step acceptance window before `agent/prompt-submit` and closes it before `turn/end`. During that window, `steer()` and `inject()` stage in one outbox; an allowed admission opens the turn, records the prompt and returned `additionalContexts`, then drains the staged input before the first request. A blocked or failed admission writes no prompt or hook-produced context. A caller-staged context-only batch then takes idle injection's immediate append, while steering and context staged beside it remain pending for retry or a later admitted prompt. Outside the window, steering becomes a waking queued prompt and injection immediately appends `user/message` without opening a turn or running the model. Every inbox enqueue publishes `agent/inbox/enqueue` with the resolved queued-or-steering placement; taking it publishes `agent/inbox/dequeue` with the same placement, and `cancel()` without `keepInbox` publishes `agent/inbox/discard`.

+Every FIFO acceptance mints an `InboxItemId` and publishes `agent/inbox/enqueue` with the complete occurrence. `updateInbox()` owns the synchronous pending-item boundary: edit freezes replacement content without changing message identity or position, remove publishes discard, and promote moves the occurrence to the head of its queued or steering FIFO; promoting queued work also makes it waking. Edit and promote publish `agent/inbox/update`. Claim publishes `agent/inbox/dequeue` and irrevocably removes the live address before prompt admission, so a racing update returns `not-found`; `cancel()` without `keepInbox` publishes `agent/inbox/discard`.

-- `agent.send(message, options)` — the one delivery primitive over the (`target` × `wakeup`) matrix. `message` is an already identified, frozen `UserMessage`; callers normally create it with `createUserMessage()` before routing begins. `SendOptions` owns only the `target` and `wakeup` policy. The agent publishes or queues the complete value as-is without minting or replacing its identity. The message's `agent/inbox/enqueue`/`dequeue`/`discard` events carry it so callers can correlate a queued item with its lifecycle; enqueue and dequeue also carry the resolved `queued | steering` placement so repeated message identities retire from the correct FIFO. `target: 'next-turn'` queues one independent FIFO item that, if admitted, becomes the sole ordinary prompt in its turn. `target: 'next-step'` with `wakeup: true` submits steering, while `target: 'next-step'` with `wakeup: false` injects durable context without running the model. The [one-send-one-turn Agent Note](../../../.agents/notes/implemented/simplification/2026-07-17-one-send-one-turn.md) owns the turn rationale.
+- `agent.send(message, options)` — the one delivery primitive over the (`target` × `wakeup`) matrix. `message` is an already identified, frozen `UserMessage`; callers normally create it with `createUserMessage()` before routing begins. `SendOptions` owns only the `target` and `wakeup` policy. Each accepted FIFO occurrence receives its own `InboxItemId`, even when callers reuse a `MessageId`; `agent/inbox/enqueue`/`update` and the terminal `dequeue` or `discard` carry that complete `InboxItem`. `target: 'next-turn'` queues one independent FIFO item that, if admitted, becomes the sole ordinary prompt in its turn. `target: 'next-step'` with `wakeup: true` submits steering, while `target: 'next-step'` with `wakeup: false` injects durable context without running the model. The [one-send-one-turn Agent Note](../../../.agents/notes/implemented/simplification/2026-07-17-one-send-one-turn.md) owns the turn rationale.
+- `agent.updateInbox(itemId, action)` — synchronously edits, removes, or promotes one still-pending occurrence. Edit keeps its `MessageId`, `InboxItemId`, source, placement, and FIFO position while replacing frozen content. Remove emits the occurrence's terminal discard. Promote moves it to the front of its current FIFO and makes an ordinary queued item waking. A claimed item has crossed the ownership boundary and returns `not-found`.
 - `agent.followup(input)` — the `next-turn`/wakeup preset of `send()`: queue an ordinary follow-up turn and wake the driver.
 - `agent.steer(input)` — the `next-step`/wakeup preset: during prompt admission or an open turn, stage steering for the next safe boundary without dispatching `agent/prompt-submit`; outside that acceptance window, delegate to a woken follow-up. Admission failure leaves staged steering for retry or a later admitted prompt, while cancellation or disposal may discard it.
 - `agent.inject(input)` — the `next-step`/no-wakeup preset: append model-facing context without running the model; the next request sees a verbatim user-role message whose provenance is carried by the required `input.source`. During prompt admission or an open turn, injection waits in the outbox for the next safe boundary. Outside that acceptance window, it appends immediately without opening a turn; a context-only admission batch takes this fallback if admission closes without a turn, while context staged beside steering remains pending with it. Persistence reacts to `session/event` independently. Injection emits no `agent/inbox/*` event.

 Session model routing is a session-domain contract. `session.models` returns the selected provider/model/reasoning target with provider-grouped advisory models, exact-route reasoning metadata, and provider-local lookup failures. `session.selectModel` validates the optional adapter-owned reasoning effort and replaces the complete target selected for the next prompt-assembly boundary. Catalog membership is not validation: an adapter may resolve an unlisted model, while an unavailable route or unsupported effort returns `model-unavailable`.
 
+Pending agent input is a live control-plane contract, not session history. The gateway mirrors complete `InboxItem` occurrences from `agent/inbox/*` and broadcasts authoritative `session/queue` snapshots on every change and reconnect. `session.updateQueue` addresses one `InboxItemId`: edit replaces pending content, remove discards it, and promote moves it to the front of its current FIFO while waking ordinary queued work. A driver claim wins races by retiring the address before admission; a later operation returns `queue-item-not-found`. The client never infers retirement from turn or status events.
+
 Workspace and Session lists are separate reconnect baselines. `workspace.create` creates a unique name or adopts an existing directory, `workspace.delete` removes only the Workspace registration, `session.create` accepts an optional preallocated Session id, and `host/workspace-changed`, `host/workspace-removed`, plus `host/session-added` carry committed increments in either arrival order. Registration deletion preserves the directory and session logs; its Sessions remain in `session.list` and become Ungrouped. `SessionSummary.blank` and the `host/session-added` frame carry the derived zero-events bit: clients hide blank sessions and reuse them per workspace, flip blank on the first `host/session-status(running:true)`, and treat `session.list` as the reconnect authority; cold summaries are never blank because lazy persistence keeps never-appended sessions out of `list()`.
 
 Directory picking delegates to the composed `ctx.directoryPicker` backend ([the directory-picker seam](../directory-picker/README.md)); a method called outside the composed capability's kind fails with `directory-picker-unavailable` (the client needs no advertisement — the composed picker package's own client half renders the matching interaction). Under `native`, `host.pickDirectory` opens one native chooser and returns its selected path (`null` on cancel); this user-paced method is the sole unary call exempt from the default 30-second timeout, and caller/connection aborts still propagate to the native process. Under `browse`, `host.listDirectory` returns one name-sorted directory level with breadcrumb ancestry, a `home` anchor, and host-owned `hidden` flags (absent path = home directory), and `host.createDirectory` creates one validated child segment; the backend's typed failures map 1:1 onto the `directory-unreadable`/`directory-exists`/`directory-create-failed` codes. The browser carrier's prefix-wide trust fence (dsh-client-connection) covers all of these like every other `/api` request.

 会话模型路由属于会话领域契约。`session.models` 返回选中的提供方／模型／推理（reasoning）目标，以及按提供方分组的建议性模型、精确路由推理元数据和逐提供方查询失败记录。`session.selectModel` 校验由适配器持有的可选推理强度，并替换将在下一提示词组装边界使用的完整目标。目录成员关系不构成校验：适配器可以解析未列出的模型，而不可用路由或不受支持的推理强度会返回 `model-unavailable`。
 
+待处理 agent 输入属于实时控制平面契约，而非会话历史。网关镜像来自 `agent/inbox/*` 的完整 `InboxItem` 单次入队项，并在每次变更和重连时广播权威的 `session/queue` 快照。`session.updateQueue` 通过 `InboxItemId` 寻址单个项：编辑会替换待处理内容，移除会将其丢弃，前移会把它移至当前 FIFO 的队首，并使普通 queued 工作能够唤醒驱动器。驱动器在接纳前退役寻址标识，因此认领会赢得竞态；之后的操作返回 `queue-item-not-found`。客户端绝不根据轮次或状态事件推断项已退役。
+
 Workspace 列表与 Session 列表是相互独立的重连基线。`workspace.create` 会创建唯一名称或接纳现有目录，`workspace.delete` 只移除 Workspace 注册记录，`session.create` 接受可选的预分配 Session id，`host/workspace-changed`、`host/workspace-removed` 与 `host/session-added` 则以任意到达顺序携带已提交的增量。删除注册记录会保留目录和会话日志；相关 Session 仍留在 `session.list` 中，并进入 Ungrouped。`SessionSummary.blank` 与 `host/session-added` 帧携带派生的零事件位：客户端隐藏空白会话并按 workspace 复用它们，在首个 `host/session-status(running:true)` 时翻转 blank，并以 `session.list` 作为重连权威；冷会话摘要永远不是空白：惰性持久化让从未追加过事件的会话根本不出现在 `list()` 中。
 
 目录选择委托给组合的 `ctx.directoryPicker` 后端（[目录选择 seam](../directory-picker/README.md)）；调用组合能力 kind 之外的方法会以 `directory-picker-unavailable` 失败（客户端不需要广播——组合的选择器包自己的 client half 渲染匹配的交互）。在 `native` 下，`host.pickDirectory` 打开一个原生选择器并返回选中路径（取消为 `null`）；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，调用方与连接的中止仍会传播至原生进程。在 `browse` 下，`host.listDirectory` 返回一个按名称排序的目录层级，携带面包屑祖先链、`home` 锚点与宿主判定的 `hidden` 标志（不带路径即家目录），`host.createDirectory` 创建一个经校验的子段；后端的类型化失败 1:1 映射为 `directory-unreadable`／`directory-exists`／`directory-create-failed` 错误码。浏览器载体的前缀级信任栅栏（dsh-client-connection）像覆盖其他所有 `/api` 请求一样覆盖上述全部方法。

 `@deepseek-ai/dsh-tool-bash-persistent` consumes `ctx.pty` and registers one `bash(command)` tool. It lazily creates one interactive shell per exact Agent and serializes that owner's calls. Cwd, exported variables, activated environments, functions, and background jobs persist. Random private markers delimit command output. Retained scrollback is paged backward to recover the command's original prefix; a dropped prefix is reported explicitly. Timeout or cancellation closes the shell before another call can reuse uncertain state, and model-visible timeout/exit results disclose that reset. The configurable description defaults to persistence facts only, so network and package-mirror claims remain deployment-owned.

Paths are absolute, mutations preserve tabs outside the requested edit, and the public schema and failures use only `old_str`.

It provides numbered text views, filtered two-level directory listings, unique literal replacement, canonical insertion boundaries, and bounded output.

The plugin can compose with persistent Bash, one-shot Bash, sandboxed Bash, or no shell.
 
 `dsh-system-prompt` accepts `includeHarnessIdentity: false`, while `dsh-agent-spine-demo` forwards that setting and accepts `toolBash: false`. A deployment can therefore own an exact persona and replace the spine's native Bash without duplicate prompt or tool registrations. Existing defaults remain unchanged.

 ## Tool
 
-The schema provides `view`, `create`, `str_replace`, and `insert` over absolute paths. File views use one-based line numbers; directory views omit hidden, dependency, and Python-cache entries and descend two levels. Replacement requires one unique literal match and reports errors only in the public `old_str` vocabulary. Insert follows the selected zero-based insertion boundary without adding an implicit trailing newline. Mutations preserve tabs outside the requested edit.

 ## Decision
 
-`@deepseek-ai/dsh-tool-bash-persistent` consumes `ctx.pty` and registers one `bash(command)` tool. It lazily creates one interactive shell per exact Agent and serializes that owner's calls. Cwd, exported variables, activated environments, functions, and background jobs persist. Random private markers delimit command output. Retained scrollback is paged backward to recover the command's original prefix; a dropped prefix is reported explicitly. Timeout or cancellation closes the shell before another call can reuse uncertain state, and model-visible timeout/exit results disclose that reset. The configurable description defaults to persistence facts only, so network and package-mirror claims remain deployment-owned.
+`@deepseek-ai/dsh-tool-bash-persistent` consumes `ctx.pty` and registers one `bash(command)` tool. It lazily creates one interactive shell per exact Agent and serializes that owner's calls. Cwd, exported variables, activated environments, functions, and background jobs persist. Random private markers delimit command output. Retained scrollback is paged backward to recover the command's original prefix; a dropped prefix is reported explicitly. A nonzero wrapped command appends `[exit code: N]`; a shell that dies before reporting that status instead appends `[shell exited: code N]`, `[shell killed by signal: SIG]`, or `[shell exited]` when the backend supplies neither. `maxOutputChars` bounds retained command output, while fixed diagnostics can extend the returned string. Timeout or cancellation closes the shell before another call can reuse uncertain state, and model-visible timeout/exit results disclose that reset. The configurable description defaults to persistence facts only, so network and package-mirror claims remain deployment-owned.
 
 `@deepseek-ai/dsh-tool-str-replace-editor` independently consumes `ctx.fs` and registers `str_replace_editor` with `view`, `create`, `str_replace`, and `insert`. It provides numbered text views, filtered two-level directory listings, unique literal replacement, canonical insertion boundaries, and bounded output. Paths are absolute; file views preserve content tabs so copied text remains valid literal replacement input; mutations preserve tabs outside the requested edit; and the public schema and failures use only `old_str`. The plugin can compose with persistent Bash, one-shot Bash, sandboxed Bash, or no shell.

 `@deepseek-ai/dsh-tool-str-replace-editor` 独立消费 `ctx.fs`，注册包含 `view`、`create`、`str_replace` 与 `insert` 的 `str_replace_editor`。它提供带行号文本查看、过滤后的两层目录列表、唯一字面量替换、规范插入边界和有界输出。路径必须为绝对路径；文件查看会保留内容中的制表符，因此复制的文本仍可作为有效的字面量替换输入；变更会保留请求编辑范围之外的制表符；公开 schema 与错误则只使用 `old_str`。它可以与持久 Bash、一次性 Bash、沙箱 Bash 或无 shell 组合。

-Commands share one shell per Agent, so cwd, exported variables, activated environments, functions, and background jobs persist across calls.

+Commands share one shell per Agent, so cwd, exported variables, activated environments, functions, and background jobs persist across calls. Results exclude private completion markers and the shell prompt. A nonzero wrapped command appends `[exit code: N]`; a shell that exits before reporting that status instead appends `[shell exited: code N]`, `[shell killed by signal: SIG]`, or `[shell exited]` when the backend supplies neither, then resets and tells the model that the next call starts fresh. Long output keeps the earliest retained prefix plus a clipping notice. If the PTY has already dropped that prefix, the result says so explicitly instead of presenting a tail as complete output. Timeout returns bounded partial output, closes the uncertain shell, and reports the reset.

 ## Decision
 
-`@deepseek-ai/dsh-tool-bash-persistent` consumes `ctx.pty` and registers one `bash(command)` tool. It lazily creates one interactive shell per exact Agent and serializes that owner's calls. Cwd, exported variables, activated environments, functions, and background jobs persist. Random private markers delimit command output. Retained scrollback is paged backward to recover the command's original prefix; a dropped prefix is reported explicitly. A nonzero wrapped command appends `[exit code: N]`; a shell that dies before reporting that status instead appends `[shell exited: code N]`, `[shell killed by signal: SIG]`, or `[shell exited]` when the backend supplies neither. `maxOutputChars` bounds retained command output, while fixed diagnostics can extend the returned string. Timeout or cancellation closes the shell before another call can reuse uncertain state, and model-visible timeout/exit results disclose that reset. The configurable description defaults to persistence facts only, so network and package-mirror claims remain deployment-owned.

 `@deepseek-ai/dsh-tool-str-replace-editor` independently consumes `ctx.fs` and registers `str_replace_editor` with `view`, `create`, `str_replace`, and `insert`. It provides numbered text views, filtered two-level directory listings, unique literal replacement, canonical insertion boundaries, and bounded output. Paths are absolute; file views preserve content tabs so copied text remains valid literal replacement input; mutations preserve tabs outside the requested edit; and the public schema and failures use only `old_str`. The plugin can compose with persistent Bash, one-shot Bash, sandboxed Bash, or no shell.

 ## 决策

 While the agent is running, ordinary editor submissions call `agent.steer()`; otherwise they call `agent.followup()`. A slash at the start of the submitted line enters `ctx.commands` instead: known commands execute directly, unknown commands produce a warning, and neither path automatically reaches the model. A command producer may explicitly schedule agent work; [`dsh-plan-mode`](../../plan/plan-mode/README.md#model-and-human-surfaces) uses that contract for `/plan [message]`. The TUI registers `/help`, `/model`, `/clear`, `/palette`, `/reload`, `/resume`, `/status`, and `/exit` as agent-scoped definitions; every other effective command joins autocomplete and `/help` dynamically, as do `/skill:` completions. A status line above the editor reports the turn phase the TUI derives from session events — waiting for the first token, thinking, responding, or executing tools — with the elapsed time in that phase and the running step total, refreshed each second, and ends with the `Enter sends steering, Esc cancels` hint; while steering messages wait to reach the model it inserts a `N queued ·` badge before the hint that clears as each drains. Ctrl+C or Escape cancels a running turn. Tool and injected-context cards collapse long bodies into a configurable head/tail preview; Ctrl+O cycles tool cards through collapsed preview, full output, and hidden — the hidden phase drops tool cards from the transcript entirely while context cards stay at their preview, since injected instructions are not tool traffic. An injected-context card renders its message as prose with the producer's outer reminder frame stripped, so neither the fold nor the frame stripping depends on the payload's syntax. Ctrl+R toggles reasoning, Ctrl+L redraws, and Ctrl+D exits while idle.
 
-`/model` opens the advisory `ctx.llm` catalog as a keyboard selector: a filter box above the list narrows rows by a case-insensitive substring over each row's `provider/model` label, model name, and description, keeping the highlighted row selected when it survives the filter; Up/Down moves, Shift+Tab cycles the focused model's adapter-advertised reasoning efforts in display order, Enter selects the model and effort, and Escape clears a non-empty filter before a second Escape closes it. When an adapter does not advertise a default effort, the cycle also includes `provider default`, which clears an explicit selection; models without selectable effort metadata ignore Shift+Tab. The selector renders the exact advertised effort list—including `off` when present—and does not synthesize, clamp, or transfer an effort between models. `/model <model>` still selects an unambiguous model id directly, while `/model <provider>/<model>` selects an exact target and uses its adapter default when one exists. The configured target or latest logged request header initializes the selector, and an unlisted current model remains visible because catalogs are advisory. Selection is local to this TUI session. Prompt assembly snapshots the target for one step, replaces `{{provider}}` and `{{model}}`, and applies the same provider/model/reasoning-effort target through `agent/request`; a switch during assembly therefore starts with a later step. The request header durably records targets that reach the model, while an unused selection remains process-local.

 `/reload` (EXPERIMENTAL, dev-only) re-reads every file-backed loader config tree and applies the diff to the running app — the HMR watcher's config path, invoked manually; it needs the cordis Loader in the context and degrades to a warning without one, runs only while the agent is idle, and refuses re-entry while a reload is in flight. Module-source hot reload remains watcher-owned. When a `skills` service is mounted, `/skill:<name> [instructions]` loads that skill's instructions into the conversation as a user turn; autocomplete lists user-invocable skills, and exact invocation rejects a skill whose user policy disables it.

Subject: [PATCH 130/212] feat(client): typed locale standard seat in the slot
 framework
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Registrations declare a dictionary namespace (locale: NS) and the renderer
synthesizes a typed t prop for the entry's component from the installed
LocaleFace; the seat binding is re-derived per locale revision, so a language
switch hands out fresh t references and memoized consumers re-render through
ordinary shallow comparison. LocaleNamespaceMap is the declare-merge table
(namespace -> dictionary key union); TranslateNS<'ns'> is the
namespace-addressed translate type (namespace keys plus the shared common
vocabulary), carried by the t seat and by the locale service's typed bind.

LocaleService implements the face (lookup ns -> common -> zh -> key,
revision-carrying snapshots with subscriber isolation) and installs it
through the boot-once slots.installLocale seam, mirroring the renderer
install. The typed register(ns, {zh, en}) overload checks each dictionary
against the namespace's key union and requires every shipped locale, so a
missing or extra key and an unbalanced translation are compile errors.
Dictionary registration bumps the face revision without emitting
locale/change — the event now means exactly 'the active locale switched',
so registration-heavy boot cannot storm event listeners.

 ## Known Limitations and Deferred Work
 
-- **Only the Settings surface is translated** — other pages keep inline copy; repo-wide extraction into dictionaries is deferred.
-- **Locale switching re-renders subscribed consumers only** — sections not wired to `locale/change` keep their rendered text until remount.
+- **Most surfaces keep inline copy** — the standard seat is adopted by the Settings rows, sidebar, question composer, and model select; the remaining packages migrate in follow-up PRs.
+- **Registry-held text reads its translation once** — copy captured at registration time outside the slot render path (e.g. the `/model` command description in the command registry) keeps the language it was registered under until re-registration; slot-rendered copy follows switches live.

Subject: [PATCH 131/212] feat(client): adopt the locale seat in theme,
 sidebar, question, and model
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Each package ships its zh/en dictionaries as satisfies-typed pairs (zh is
the key-set source of truth; en is checked complete against it), merges its
namespace into LocaleNamespaceMap, and declares locale: NS at register —
components read the framework-injected typed t seat instead of a
hand-carried inject member. Overlapping verbatim words (retry, submit,
submitting) drop out of package dictionaries in favor of the shared common
vocabulary; the question composer stores validation feedback as dictionary
keys so shown feedback follows a locale switch.

A pinned `node-pty` patch checks `DSH_NODE_PTY_SPAWN_HELPER` first, so it remains a true override for a current external consumer that supplies a non-sibling helper. When the override is unset, the patch resolves the packaged executable sibling if present and otherwise preserves upstream lookup in ordinary Node runs. The macOS executable and runtime-wheel builders inspect the thin Mach-O header and fail before publication when the helper is absent, mismatched, or not executable.

-- **exe (production)** — a single-file Node executable `dsh-jsonrpc-agent-pkg-<platform>-<arch>` (platform: `linux`/`macos`; arch: `x64`/`arm64`). macOS builds also ship the native `-spawn-helper` sibling that `node-pty` uses there, and its thin Mach-O header must match the target. No Node installation is needed on the target machine. This is the only carrier that ships in wheel distributions; this package does not publish sdists.

 - **node (dev-only)** — the full deploy closure under `runtime/node/` (`package.json` + `node_modules/`), executed as `node runtime/node/node_modules/@deepseek-ai/dsh-jsonrpc-demo/lib/bin.js` on a system Node >= 22.19. It is the current checkout's source build, meant for repo-local development and verification only; it is never selected automatically and is excluded from distributions.
 
 Both carriers hold the same content, defined once: the [package.json](package.json) at this package's root is the deploy root of the single-exe pipeline — a pure dependency manifest (no code of its own) whose dependency closure IS both the plugin set compiled into the exe and the tree materialized into `runtime/node/`. Adding a plugin to the distribution means adding one dependency line there and rebuilding.

@@ -19,7 +19,7 @@ Placement and policy rulings folded into this decision:
 - **Not the `ctx.fs` seam.** `packages/fs/` is the model/session-facing storage stack (policy events, sandbox-swappable backends). Riding it would couple GUI browsing to the model's confinement backend — swapping `fs-sandbox` for the model must never change GUI behavior — and OS facts (home anchoring, hidden conventions) are not storage primitives. The picker seam stays presentation-free and model-free; `packages/host/` is its consumer-domain home.
 - **Dependency survey (hand-roll vs adopt).** Node's stdlib *is* the maintained cross-platform OS layer (`readdir(withFileTypes)`, `homedir`, path semantics); surveyed alternatives fail the dependency bar — file-manager packages (`node-file-manager`, `files-and-folders`, Syncfusion's provider) are whole HTTP apps (fit), drive-letter helpers (`drivelist` native addon, `windows-drive-letters` ~7y stale) fail health/proportionality. The browse backend is a thin adapter over stdlib.
 - **Hidden entries: return-and-flag.** The host stamps `hidden` (POSIX dot convention) and returns everything; the client filters. Display policy stays client-side, and the show-hidden toggle shipped as exactly that client-only change: a fixed-label footer toggle whose state lives in the pressed presentation (`aria-pressed` + check glyph), a dot-led path-draft prefix reveals the hidden entries it names, and the current selection is exempt from both the hidden and the prefix filter (it anchors the two-pane view). Windows' `FILE_ATTRIBUTE_HIDDEN` is not exposed by dirents — documented limitation until a native probe pays for itself.
-- **Path-editor cancel scope: the dialog card.** The browse client's path editor cancels on Escape and on focus leaving the card, both observed at a card-scope wrapper rather than the input — after Tab parks focus on a filtered row the input is off the event path, yet Escape must collapse the editor (not the dialog) and a later focus departure must still cancel. Non-cancel exemptions: window/tab focus loss, in-card focus moves, and pointer paths (rows and the toggle suppress focus steal on mousedown while editing). Separators for seeding and draft-tail filtering are inferred from `listing.home`; the wire-field alternative below records the deferred authoritative form. Combobox semantics between the editor and the list it filters (`aria-expanded`/`aria-controls`/active-descendant, result announcements) are likewise deferred — today they read to assistive tech as separate widgets. Focus parking is a card-wide invariant, not an editor-only one: every pick — editing or not, including right-pane advances and create landings whose columns are replaced — re-parks focus on the selection's row after commit, while every other displacing exit (Enter, Escape, a navigation landing whose new level dropped the focused row, a failed pick or create relist, and the nested create dialog closing) falls back to the crumb edit zone whenever focus actually fell to body; keyboard traversal never falls out of the card (the Modal has no focus trap), except during the owner's adopt window, where `busy` inerts every control and the dialog is closing either way.

Non-cancel exemptions: window/tab focus loss, in-card focus moves, and pointer paths (rows and the toggle suppress focus steal on mousedown while editing).

 - **Navigation lands selection-anchored, progressively.** Away from the display root (the same collapse the crumb header renders, so crumbs and pane shape never disagree), the browse client's navigate commits the target level the moment it arrives — the editor closes and loading ends on that first settlement, so an Enter-submitted navigation is never withdrawn waiting on more — and a parent leg then upgrades the landing in place: the target's actual parent-level entry re-selected (platform case folding on Windows), its children on the right, so a crumb jump reads as stepping back one pane rather than collapsing to a single column. The parent leg runs under the landing's supersession scope and is aborted on the wire by any newer intent; a failed parent leg, or a truncated parent window lacking the target, leaves the committed single-pane landing — the upgrade must never orphan the selection it exists to anchor. Known boundaries of the progressive shape: a pointer press landing exactly inside the one-RTT upgrade window can lose its click when the pressed row node is replaced (keyboard focus is re-parked on the re-selected row; the pointer window is accepted); on slash platforms (macOS) only a final-segment case drift misses the parent-entry match and keeps the single-pane landing, while ancestor-segment drift still matches — parent entry paths inherit the typed prefix — and lands two panes at the cost of the Home collapse; and navigate always relists both legs even when the target is the currently shown level — a crumb tap doubles as the refresh gesture, so freshness wins over reusing possibly-stale in-hand listings at the cost of up to two host scans.
 - **Symlinks: follow for enterability.** `stat` probes symlinks (broken/cyclic → skipped); crumbs keep the logical path the operator navigated, and `workspace.create` already canonicalizes via realpath at adoption.
 - **Listing levels are bounded, and streamed.** One `list` call returns at most `maxEntries` rows (config, default 1000 — GitHub's web-UI directory-listing bound). The level streams via `opendir` into a name-sorted window of `maxEntries + 1` candidates, so memory stays O(maxEntries) and enterability probing touches only windowed candidates; the wire `DirectoryListing` carries a required `truncated` flag so the client states incompleteness instead of silently missing tail entries. A windowed broken symlink is not backfilled from beyond the window — the eviction already marks the level truncated. Window insertion is binary with an O(1) full-window tail rejection (an oversized level must not pay a window scan per dirent), and `list(path, signal)` threads the carrier's request signal so a scan of a stalled network directory cannot outlive a disconnected caller — every await in the scan (open, each read, each symlink probe) races the signal, an aborted exit abandons rather than awaits the close (Node queues close behind in-flight reads), and abandoned settlements are swallowed so cleanup can never surface as an unhandled rejection. An unbounded level is a memory/responsiveness hole for large or adversarial directories.

 - **Adopting a file-manager/drive-enumeration dependency.** Rejected per the survey above; recorded here as the dependency policy requires.
 - **A flip-label show-hidden toggle ("Hide hidden files").** Rejected: a flipping action label is ambiguous between state and action and doubles the negative; the fixed label with a pressed presentation states both at once.
 - **Pure relatedTarget blur cancellation (no mousedown suppression).** Rejected: Safari does not focus buttons on pointer down, so a click's focusout carries a null `relatedTarget` and would cancel the editor before the click lands; editing-scoped mousedown suppression plus the card-anchored relatedTarget guard covers pointer and keyboard paths together.
-- **A wire `separator` field on `DirectoryListing` (host stamps `path.sep`).** Deferred, not rejected: it is the authoritative form — a POSIX home directory containing a backslash defeats the `listing.home` heuristic — but it touches the seam type and every backend; the browse client's `separatorOf` carries a TODO pointing at this alternative until a wire change is next scheduled.
+- **A wire `separator` field on `DirectoryListing` (host stamps `path.sep`).** Deferred, not rejected: it is the authoritative form. The root-crumb read the client uses today is exact for every root shape this backend emits, but it still infers a platform fact from path text and promotes "the chain starts at the root" from backend behavior into a client-relied invariant (the `crumbs` JSDoc does promise it), and it degrades to the old home-text heuristic on an empty chain; a wire field would travel verbatim and survive empty chains and future backends. It touches the seam type and every backend, so the browse client's `separatorOf` carries a TODO pointing at this alternative until a wire change is next scheduled.

 - **不用 `ctx.fs` seam。** `packages/fs/` 是面向模型／会话的存储栈（policy 事件、sandbox 可换后端）。骑上去会把 GUI 浏览耦合进模型的限制后端——为模型换 `fs-sandbox` 绝不能改变 GUI 行为——而 OS 事实（home 锚定、隐藏约定）也不是存储原语。picker seam 保持无展示、无模型；`packages/host/` 是它消费方域的家。
 - **依赖调研（手写 vs 引入）。** Node 标准库本身就是维护中的跨平台 OS 层（`readdir(withFileTypes)`、`homedir`、路径语义）；调研过的替代品都过不了依赖门槛——文件管理器包（`node-file-manager`、`files-and-folders`、Syncfusion 的 provider）是整套 HTTP 应用（契合度不过），盘符工具（原生插件 `drivelist`、约七年未更的 `windows-drive-letters`）健康度／比例失当。browse 后端是标准库上的薄适配。
 - **隐藏条目：返回并打标。** 宿主标注 `hidden`（POSIX 点前缀约定）并返回全部条目；客户端过滤。展示策略留在客户端，"显示隐藏"开关正是作为这一纯客户端改动落地：标签固定的 footer 开关，其状态由按下态呈现承载（`aria-pressed` + 勾选符号）；以点开头的路径草稿前缀会显出它所指名的隐藏条目；当前选中项则不受隐藏与前缀两种过滤影响（它锚定着双栏视图）。Windows 的 `FILE_ATTRIBUTE_HIDDEN` 不被 dirent 暴露——记为限制，直到原生探测值回其成本。
-- **路径编辑器的取消范围：对话框卡片。** browse 客户端的路径编辑器在按 Escape 与焦点离开卡片时取消，两者都在卡片范围的包装层而非输入框上监听——Tab 把焦点停到某个过滤命中的行之后，输入框已不在事件路径上，但 Escape 仍须收起编辑器（而非对话框），其后的焦点离开也仍须取消。不取消的豁免：窗口／标签页失焦、卡片内焦点移动，以及指针路径（编辑期间行与开关在 mousedown 时抑制焦点夺取）。预填与草稿末段过滤所用的分隔符从 `listing.home` 推断；下文的线上字段替代方案记录了被延期的权威形态。编辑器与其过滤的列表之间的 combobox 语义（`aria-expanded`／`aria-controls`／active-descendant、结果播报）同样被延期——目前二者在辅助技术看来是彼此独立的控件。焦点停靠是卡片全域的不变量，而非编辑器独有：每次选取——无论是否处于编辑态，包括右栏推进与各列被替换的创建落地——提交后都把焦点重新停靠到选中项所在的行上，而其余所有会顶离焦点的退出（Enter、Escape、新层级已不含焦点所在行的导航落地、选取或创建失败后的重新列举，以及嵌套创建对话框的关闭）只要焦点确实落到了 body 上，就回落到 crumb 编辑区；键盘遍历绝不会落出卡片之外（Modal 没有焦点陷阱），仅 owner 的接纳窗口期间例外——此时 `busy` 把每个控件置为惰性，且对话框反正正在关闭。

 - **导航以选中项为锚、渐进落地。** 在展示根之外（与 crumb 头部渲染的是同一塌缩，因此 crumb 与分栏形态永不相左），browse 客户端的导航在目标层级到达的那一刻即提交它——这次首个落定即关闭编辑器并结束加载，因此 Enter 提交的导航绝不会为等待更多内容而被撤回——随后父层级这一程就地升级这次落地：重新选中目标在父层级中的实际条目（Windows 上按平台惯例折叠大小写），右侧展示其子项，因此 crumb 跳转读作后退一栏，而不是塌缩成单列。父层级这一程在落地的 supersession 范围下运行，任何较新的意图都会在线上将其中止；父层级这一程失败，或被截断的父窗口缺少目标时，都保留已提交的单栏落地——升级的存在正是为了锚定选中项，绝不能反而让它悬空。渐进形态的已知边界：指针按压若恰好落在单个 RTT 的升级窗口内，可能因所按行节点被替换而丢失点击（键盘焦点会重新停靠到重新选中的行上；指针的这段窗口则被接受）；斜杠平台（macOS）上仅末段的大小写偏差会错过父层级条目匹配，保留单栏落地，而祖先段的偏差仍能匹配——父层级条目路径继承键入的前缀——并落地双栏，代价是 Home 塌缩；且导航总是重新列举两程，哪怕目标就是当前展示的层级——crumb 点按兼作刷新手势，因此宁要新鲜度也不复用手头可能已陈旧的列举，代价是至多两次宿主扫描。
 - **符号链接：为可进入性而跟随。** 用 `stat` 探测符号链接（断链／循环→跳过）；面包屑保留操作者导航的逻辑路径，`workspace.create` 在接纳时本就做 realpath 规范化。
 - **列举层级有上限，且流式处理。** 单次 `list` 至多返回 `maxEntries` 行（配置项，默认 1000——GitHub 网页端目录列举的同一上限）。层级经 `opendir` 流入一个按名排序、容量 `maxEntries + 1` 的候选窗口，内存保持 O(maxEntries)，可进入性探测只触及窗口内候选；线上 `DirectoryListing` 携带必填的 `truncated` 标志，让客户端明示不完整而不是静默缺尾。窗口内的断链符号链接不从窗口外回填——发生过驱逐本身已把层级标记为截断。窗口插入为二分查找、满窗尾部单次比较即拒绝（超大层级不能为每个 dirent 付出一次全窗扫描），且 `list(path, signal)` 透传载体的请求信号，滞塞网络目录的扫描不会在调用方断连后继续存活——扫描中的每个 await（打开、每次读取、每次符号链接探测）都与信号赛跑，中止路径放弃而非等待 close（Node 会把 close 排在在飞读取之后），被放弃的 settlement 全部吞掉，清理不会以未处理拒绝的形式冒出。无上限的层级对超大或恶意构造的目录就是内存／响应性漏洞。

It gives up product-role colocation and creates path churn on promotion, while the npm name remains stable. The subtree rules, repository [current-owner/current-need rule](../../../../packages/AGENTS.md), and unchanged engineering gates limit junk-drawer growth. Because official release tooling does not yet exist, contributor policy enforces the exclusion; the directory is its required exclusion boundary when added.

+Every scenario compares `stdout.expected.jsonl` with cwd-rooted separators canonicalized to `/`. On Windows, `pinsNativeWindowsStdout` additionally compares the complete `stdout.expected.windows.jsonl` after the shared expected output and requires that sidecar exactly when enabled. A scenario requiring a non-Windows host declares `posixOnly`, which skips its run test on Windows while the fixture guards keep covering its committed files everywhere; examples include POSIX process semantics (e.g. cancelling a live bash call kills a detached process group) and generated paths Windows cannot represent.
 
 The example also ships a `cordis.snapshot.yml` replay overlay next to its `cordis.yml` (the bin swaps them under `DSH_SNAPSHOT=replay` — [single-source replay config Agent Note](../../../.agents/notes/archived/testing/2026-07-04-single-source-acp-replay-config.md)); replay fixtures are served by [`dsh-llm-replay`](../llm-replay/README.md), which this package points at via the `DSH_SNAPSHOT_*` env vars it sets on the child. `pnpm run test:snapshot:record` calls the live LLM and rewrites the recorded scenarios' model fixtures; `pnpm run test:snapshot:refresh` stays keyless, runs the replay overlay, and rewrites stdout, comparable session-log expected outputs, and owned prompt and tool-schema sidecars from the committed model scripts. Fixture roles, record/replay/refresh semantics, and scenario-table fields are documented on `Scenario` and in the [snapshot Agent Note](../../../.agents/notes/implemented/testing/2026-06-19-acp-snapshot-tests.md).

@@ -19,7 +19,7 @@ Placement and policy rulings folded into this decision:
 - **Not the `ctx.fs` seam.** `packages/fs/` is the model/session-facing storage stack (policy events, sandbox-swappable backends). Riding it would couple GUI browsing to the model's confinement backend — swapping `fs-sandbox` for the model must never change GUI behavior — and OS facts (home anchoring, hidden conventions) are not storage primitives. The picker seam stays presentation-free and model-free; `packages/host/` is its consumer-domain home.
 - **Dependency survey (hand-roll vs adopt).** Node's stdlib *is* the maintained cross-platform OS layer (`readdir(withFileTypes)`, `homedir`, path semantics); surveyed alternatives fail the dependency bar — file-manager packages (`node-file-manager`, `files-and-folders`, Syncfusion's provider) are whole HTTP apps (fit), drive-letter helpers (`drivelist` native addon, `windows-drive-letters` ~7y stale) fail health/proportionality. The browse backend is a thin adapter over stdlib.
 - **Hidden entries: return-and-flag.** The host stamps `hidden` (POSIX dot convention) and returns everything; the client filters. Display policy stays client-side, and the show-hidden toggle shipped as exactly that client-only change: a fixed-label footer toggle whose state lives in the pressed presentation (`aria-pressed` + check glyph), a dot-led path-draft prefix reveals the hidden entries it names, and the current selection is exempt from both the hidden and the prefix filter (it anchors the two-pane view). Windows' `FILE_ATTRIBUTE_HIDDEN` is not exposed by dirents — documented limitation until a native probe pays for itself.
-- **Path-editor cancel scope: the dialog card.** The browse client's path editor cancels on Escape and on focus leaving the card, both observed at a card-scope wrapper rather than the input — after Tab parks focus on a filtered row the input is off the event path, yet Escape must collapse the editor (not the dialog) and a later focus departure must still cancel. Non-cancel exemptions: window/tab focus loss, in-card focus moves, and pointer paths (rows and the toggle suppress focus steal on mousedown while editing). Separators for seeding and draft-tail filtering are read from the host-resolved root crumb (exact for every root form this backend emits: `/`, `C:\`, `\\server\share\`); the wire-field alternative below records the deferred authoritative form. Combobox semantics between the editor and the list it filters (`aria-expanded`/`aria-controls`/active-descendant, result announcements) are likewise deferred — today they read to assistive tech as separate widgets. Focus parking is a card-wide invariant, not an editor-only one: every pick — editing or not, including right-pane advances and create landings whose columns are replaced — re-parks focus on the selection's row after commit, while every other displacing exit (Enter, Escape, a navigation landing whose new level dropped the focused row, a failed pick or create relist, and the nested create dialog closing) falls back to the crumb edit zone whenever focus actually fell to body; keyboard traversal never falls out of the card (the Modal has no focus trap), except during the owner's adopt window, where `busy` inerts every control and the dialog is closing either way.

 - **Navigation lands selection-anchored, progressively.** Away from the display root (the same collapse the crumb header renders, so crumbs and pane shape never disagree), the browse client's navigate commits the target level the moment it arrives — the editor closes and loading ends on that first settlement, so an Enter-submitted navigation is never withdrawn waiting on more — and a parent leg then upgrades the landing in place: the target's actual parent-level entry re-selected (platform case folding on Windows), its children on the right, so a crumb jump reads as stepping back one pane rather than collapsing to a single column. The parent leg runs under the landing's supersession scope and is aborted on the wire by any newer intent; a failed parent leg, or a truncated parent window lacking the target, leaves the committed single-pane landing — the upgrade must never orphan the selection it exists to anchor. Known boundaries of the progressive shape: a pointer press landing exactly inside the one-RTT upgrade window can lose its click when the pressed row node is replaced (keyboard focus is re-parked on the re-selected row; the pointer window is accepted); on slash platforms (macOS) only a final-segment case drift misses the parent-entry match and keeps the single-pane landing, while ancestor-segment drift still matches — parent entry paths inherit the typed prefix — and lands two panes at the cost of the Home collapse; and navigate always relists both legs even when the target is the currently shown level — a crumb tap doubles as the refresh gesture, so freshness wins over reusing possibly-stale in-hand listings at the cost of up to two host scans.
 - **Symlinks: follow for enterability.** `stat` probes symlinks (broken/cyclic → skipped); crumbs keep the logical path the operator navigated, and `workspace.create` already canonicalizes via realpath at adoption.
 - **Listing levels are bounded, and streamed.** One `list` call returns at most `maxEntries` rows (config, default 1000 — GitHub's web-UI directory-listing bound). The level streams via `opendir` into a name-sorted window of `maxEntries + 1` candidates, so memory stays O(maxEntries) and enterability probing touches only windowed candidates; the wire `DirectoryListing` carries a required `truncated` flag so the client states incompleteness instead of silently missing tail entries. A windowed broken symlink is not backfilled from beyond the window — the eviction already marks the level truncated. Window insertion is binary with an O(1) full-window tail rejection (an oversized level must not pay a window scan per dirent), and `list(path, signal)` threads the carrier's request signal so a scan of a stalled network directory cannot outlive a disconnected caller — every await in the scan (open, each read, each symlink probe) races the signal, an aborted exit abandons rather than awaits the close (Node queues close behind in-flight reads), and abandoned settlements are swallowed so cleanup can never surface as an unhandled rejection. An unbounded level is a memory/responsiveness hole for large or adversarial directories.

@@ -19,7 +19,7 @@ web GUI 的"打开本地文件夹"流程被焊死在一种交互上：`host.pick
 - **不用 `ctx.fs` seam。** `packages/fs/` 是面向模型／会话的存储栈（policy 事件、sandbox 可换后端）。骑上去会把 GUI 浏览耦合进模型的限制后端——为模型换 `fs-sandbox` 绝不能改变 GUI 行为——而 OS 事实（home 锚定、隐藏约定）也不是存储原语。picker seam 保持无展示、无模型；`packages/host/` 是它消费方域的家。
 - **依赖调研（手写 vs 引入）。** Node 标准库本身就是维护中的跨平台 OS 层（`readdir(withFileTypes)`、`homedir`、路径语义）；调研过的替代品都过不了依赖门槛——文件管理器包（`node-file-manager`、`files-and-folders`、Syncfusion 的 provider）是整套 HTTP 应用（契合度不过），盘符工具（原生插件 `drivelist`、约七年未更的 `windows-drive-letters`）健康度／比例失当。browse 后端是标准库上的薄适配。
 - **隐藏条目：返回并打标。** 宿主标注 `hidden`（POSIX 点前缀约定）并返回全部条目；客户端过滤。展示策略留在客户端，"显示隐藏"开关正是作为这一纯客户端改动落地：标签固定的 footer 开关，其状态由按下态呈现承载（`aria-pressed` + 勾选符号）；以点开头的路径草稿前缀会显出它所指名的隐藏条目；当前选中项则不受隐藏与前缀两种过滤影响（它锚定着双栏视图）。Windows 的 `FILE_ATTRIBUTE_HIDDEN` 不被 dirent 暴露——记为限制，直到原生探测值回其成本。
-- **路径编辑器的取消范围：对话框卡片。** browse 客户端的路径编辑器在按 Escape 与焦点离开卡片时取消，两者都在卡片范围的包装层而非输入框上监听——Tab 把焦点停到某个过滤命中的行之后，输入框已不在事件路径上，但 Escape 仍须收起编辑器（而非对话框），其后的焦点离开也仍须取消。不取消的豁免：窗口／标签页失焦、卡片内焦点移动，以及指针路径（编辑期间行与开关在 mousedown 时抑制焦点夺取）。预填与草稿末段过滤所用的分隔符从宿主解析的根 crumb 读取（对该后端发出的每种根形态都精确：`/`、`C:\`、`\\server\share\`）；下文的线上字段替代方案记录了被延期的权威形态。编辑器与其过滤的列表之间的 combobox 语义（`aria-expanded`／`aria-controls`／active-descendant、结果播报）同样被延期——目前二者在辅助技术看来是彼此独立的控件。焦点停靠是卡片全域的不变量，而非编辑器独有：每次选取——无论是否处于编辑态，包括右栏推进与各列被替换的创建落地——提交后都把焦点重新停靠到选中项所在的行上，而其余所有会顶离焦点的退出（Enter、Escape、新层级已不含焦点所在行的导航落地、选取或创建失败后的重新列举，以及嵌套创建对话框的关闭）只要焦点确实落到了 body 上，就回落到 crumb 编辑区；键盘遍历绝不会落出卡片之外（Modal 没有焦点陷阱），仅 owner 的接纳窗口期间例外——此时 `busy` 把每个控件置为惰性，且对话框反正正在关闭。

 - **导航以选中项为锚、渐进落地。** 在展示根之外（与 crumb 头部渲染的是同一塌缩，因此 crumb 与分栏形态永不相左），browse 客户端的导航在目标层级到达的那一刻即提交它——这次首个落定即关闭编辑器并结束加载，因此 Enter 提交的导航绝不会为等待更多内容而被撤回——随后父层级这一程就地升级这次落地：重新选中目标在父层级中的实际条目（Windows 上按平台惯例折叠大小写），右侧展示其子项，因此 crumb 跳转读作后退一栏，而不是塌缩成单列。父层级这一程在落地的 supersession 范围下运行，任何较新的意图都会在线上将其中止；父层级这一程失败，或被截断的父窗口缺少目标时，都保留已提交的单栏落地——升级的存在正是为了锚定选中项，绝不能反而让它悬空。渐进形态的已知边界：指针按压若恰好落在单个 RTT 的升级窗口内，可能因所按行节点被替换而丢失点击（键盘焦点会重新停靠到重新选中的行上；指针的这段窗口则被接受）；斜杠平台（macOS）上仅末段的大小写偏差会错过父层级条目匹配，保留单栏落地，而祖先段的偏差仍能匹配——父层级条目路径继承键入的前缀——并落地双栏，代价是 Home 塌缩；且导航总是重新列举两程，哪怕目标就是当前展示的层级——crumb 点按兼作刷新手势，因此宁要新鲜度也不复用手头可能已陈旧的列举，代价是至多两次宿主扫描。
 - **符号链接：为可进入性而跟随。** 用 `stat` 探测符号链接（断链／循环→跳过）；面包屑保留操作者导航的逻辑路径，`workspace.create` 在接纳时本就做 realpath 规范化。
 - **列举层级有上限，且流式处理。** 单次 `list` 至多返回 `maxEntries` 行（配置项，默认 1000——GitHub 网页端目录列举的同一上限）。层级经 `opendir` 流入一个按名排序、容量 `maxEntries + 1` 的候选窗口，内存保持 O(maxEntries)，可进入性探测只触及窗口内候选；线上 `DirectoryListing` 携带必填的 `truncated` 标志，让客户端明示不完整而不是静默缺尾。窗口内的断链符号链接不从窗口外回填——发生过驱逐本身已把层级标记为截断。窗口插入为二分查找、满窗尾部单次比较即拒绝（超大层级不能为每个 dirent 付出一次全窗扫描），且 `list(path, signal)` 透传载体的请求信号，滞塞网络目录的扫描不会在调用方断连后继续存活——扫描中的每个 await（打开、每次读取、每次符号链接探测）都与信号赛跑，中止路径放弃而非等待 close（Node 会把 close 排在在飞读取之后），被放弃的 settlement 全部吞掉，清理不会以未处理拒绝的形式冒出。无上限的层级对超大或恶意构造的目录就是内存／响应性漏洞。

Subject: [PATCH 140/212] =?UTF-8?q?fix(web):=20repair=20merge=20tails=20?=
 =?UTF-8?q?=E2=80=94=20todo-row=20selector=20and=20composer=20handler=20cl?=
 =?UTF-8?q?one?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The #921 selector change and the duplication gate both first ran against
this branch after the merge made it MERGEABLE: assembly-surfaces still
queried the retired data-sample="todo-row" hook (the composed TodoRow
carries ToolRow's data-tool attribute instead), and the redesigned
QuestionComposer duplicated the custom-draft onChange/onKeyDown pair
across its inline input and optionless textarea. The spec now anchors on
data-tool="todo_write", and the composer shares one draftCustom /
continueFromCustom handler pair (Enter continues, Shift+Enter stays a
newline, IME composition stays inert).

 the clone gate

The two overload declarations differ only in the inject share; folding them
would lose per-overload inference of I, so the duplication is deliberate.

@@ -19,7 +19,7 @@ Placement and policy rulings folded into this decision:
 - **Not the `ctx.fs` seam.** `packages/fs/` is the model/session-facing storage stack (policy events, sandbox-swappable backends). Riding it would couple GUI browsing to the model's confinement backend — swapping `fs-sandbox` for the model must never change GUI behavior — and OS facts (home anchoring, hidden conventions) are not storage primitives. The picker seam stays presentation-free and model-free; `packages/host/` is its consumer-domain home.
 - **Dependency survey (hand-roll vs adopt).** Node's stdlib *is* the maintained cross-platform OS layer (`readdir(withFileTypes)`, `homedir`, path semantics); surveyed alternatives fail the dependency bar — file-manager packages (`node-file-manager`, `files-and-folders`, Syncfusion's provider) are whole HTTP apps (fit), drive-letter helpers (`drivelist` native addon, `windows-drive-letters` ~7y stale) fail health/proportionality. The browse backend is a thin adapter over stdlib.
 - **Hidden entries: return-and-flag.** The host stamps `hidden` (POSIX dot convention) and returns everything; the client filters. Display policy stays client-side, and the show-hidden toggle shipped as exactly that client-only change: a fixed-label footer toggle whose state lives in the pressed presentation (`aria-pressed` + check glyph), a dot-led path-draft prefix reveals the hidden entries it names, and the current selection is exempt from both the hidden and the prefix filter (it anchors the two-pane view). Windows' `FILE_ATTRIBUTE_HIDDEN` is not exposed by dirents — documented limitation until a native probe pays for itself.
-- **Path-editor cancel scope: the dialog card.** The browse client's path editor cancels on Escape and on focus leaving the card, both observed at a card-scope wrapper rather than the input — after Tab parks focus on a filtered row the input is off the event path, yet Escape must collapse the editor (not the dialog) and a later focus departure must still cancel. Non-cancel exemptions: window/tab focus loss, in-card focus moves, and pointer paths (rows and the toggle suppress focus steal on mousedown while editing). Separators for seeding and draft-tail filtering are read from the host-resolved root crumb (exact for every root form this backend emits: `/`, `C:\`, `\\server\share\`); the wire-field alternative below records the deferred authoritative form. Combobox semantics between the editor and the list it filters (`aria-expanded`/`aria-controls`/active-descendant, result announcements) are likewise deferred — today they read to assistive tech as separate widgets. Focus parking is a card-wide invariant, not an editor-only one: every pick — editing or not, including right-pane advances and create landings whose columns are replaced — re-parks focus on the selection's row after commit, while every other displacing exit (Enter, Escape, a navigation landing whose new level dropped the focused row, a failed pick or create relist, and the nested create dialog closing) falls back to the crumb edit zone whenever focus actually fell to body, and a show-hidden toggle click that finds focus among the rows parks synchronously on the toggle itself; keyboard traversal never falls out of the card (the Modal has no focus trap), except during the owner's adopt window, where `busy` inerts every control and the dialog is closing either way.

The guarantee is scoped to the dialog's own node replacements — the Modal has no focus trap, so tabbing past the card's edge legitimately leaves, and the owner's adopt window (where `busy` inerts every control and the dialog is closing either way) is likewise outside it.
 - **Navigation lands selection-anchored, progressively.** Away from the display root (the same collapse the crumb header renders, so crumbs and pane shape never disagree), the browse client's navigate commits the target level the moment it arrives — the editor closes and loading ends on that first settlement, so an Enter-submitted navigation is never withdrawn waiting on more — and a parent leg then upgrades the landing in place: the target's actual parent-level entry re-selected (platform case folding on Windows), its children on the right, so a crumb jump reads as stepping back one pane rather than collapsing to a single column. The parent leg runs under the landing's supersession scope and is aborted on the wire by any newer intent; a failed parent leg, or a truncated parent window lacking the target, leaves the committed single-pane landing — the upgrade must never orphan the selection it exists to anchor. Known boundaries of the progressive shape: a pointer press landing exactly inside the one-RTT upgrade window can lose its click when the pressed row node is replaced (keyboard focus is re-parked on the re-selected row; the pointer window is accepted); on slash platforms (macOS) only a final-segment case drift misses the parent-entry match and keeps the single-pane landing, while ancestor-segment drift still matches — parent entry paths inherit the typed prefix — and lands two panes at the cost of the Home collapse; and navigate always relists both legs even when the target is the currently shown level — a crumb tap doubles as the refresh gesture, so freshness wins over reusing possibly-stale in-hand listings at the cost of up to two host scans.
 - **Symlinks: follow for enterability.** `stat` probes symlinks (broken/cyclic → skipped); crumbs keep the logical path the operator navigated, and `workspace.create` already canonicalizes via realpath at adoption.
 - **Listing levels are bounded, and streamed.** One `list` call returns at most `maxEntries` rows (config, default 1000 — GitHub's web-UI directory-listing bound). The level streams via `opendir` into a name-sorted window of `maxEntries + 1` candidates, so memory stays O(maxEntries) and enterability probing touches only windowed candidates; the wire `DirectoryListing` carries a required `truncated` flag so the client states incompleteness instead of silently missing tail entries. A windowed broken symlink is not backfilled from beyond the window — the eviction already marks the level truncated. Window insertion is binary with an O(1) full-window tail rejection (an oversized level must not pay a window scan per dirent), and `list(path, signal)` threads the carrier's request signal so a scan of a stalled network directory cannot outlive a disconnected caller — every await in the scan (open, each read, each symlink probe) races the signal, an aborted exit abandons rather than awaits the close (Node queues close behind in-flight reads), and abandoned settlements are swallowed so cleanup can never surface as an unhandled rejection. An unbounded level is a memory/responsiveness hole for large or adversarial directories.

 - **不用 `ctx.fs` seam。** `packages/fs/` 是面向模型／会话的存储栈（policy 事件、sandbox 可换后端）。骑上去会把 GUI 浏览耦合进模型的限制后端——为模型换 `fs-sandbox` 绝不能改变 GUI 行为——而 OS 事实（home 锚定、隐藏约定）也不是存储原语。picker seam 保持无展示、无模型；`packages/host/` 是它消费方域的家。
 - **依赖调研（手写 vs 引入）。** Node 标准库本身就是维护中的跨平台 OS 层（`readdir(withFileTypes)`、`homedir`、路径语义）；调研过的替代品都过不了依赖门槛——文件管理器包（`node-file-manager`、`files-and-folders`、Syncfusion 的 provider）是整套 HTTP 应用（契合度不过），盘符工具（原生插件 `drivelist`、约七年未更的 `windows-drive-letters`）健康度／比例失当。browse 后端是标准库上的薄适配。
 - **隐藏条目：返回并打标。** 宿主标注 `hidden`（POSIX 点前缀约定）并返回全部条目；客户端过滤。展示策略留在客户端，"显示隐藏"开关正是作为这一纯客户端改动落地：标签固定的 footer 开关，其状态由按下态呈现承载（`aria-pressed` + 勾选符号）；以点开头的路径草稿前缀会显出它所指名的隐藏条目；当前选中项则不受隐藏与前缀两种过滤影响（它锚定着双栏视图）。Windows 的 `FILE_ATTRIBUTE_HIDDEN` 不被 dirent 暴露——记为限制，直到原生探测值回其成本。
-- **路径编辑器的取消范围：对话框卡片。** browse 客户端的路径编辑器在按 Escape 与焦点离开卡片时取消，两者都在卡片范围的包装层而非输入框上监听——Tab 把焦点停到某个过滤命中的行之后，输入框已不在事件路径上，但 Escape 仍须收起编辑器（而非对话框），其后的焦点离开也仍须取消。不取消的豁免：窗口／标签页失焦、卡片内焦点移动，以及指针路径（编辑期间行与开关在 mousedown 时抑制焦点夺取）。预填与草稿末段过滤所用的分隔符从宿主解析的根 crumb 读取（对该后端发出的每种根形态都精确：`/`、`C:\`、`\\server\share\`）；下文的线上字段替代方案记录了被延期的权威形态。编辑器与其过滤的列表之间的 combobox 语义（`aria-expanded`／`aria-controls`／active-descendant、结果播报）同样被延期——目前二者在辅助技术看来是彼此独立的控件。焦点停靠是卡片全域的不变量，而非编辑器独有：每次选取——无论是否处于编辑态，包括右栏推进与各列被替换的创建落地——提交后都把焦点重新停靠到选中项所在的行上，而其余所有会顶离焦点的退出（Enter、Escape、新层级已不含焦点所在行的导航落地、选取或创建失败后的重新列举，以及嵌套创建对话框的关闭）只要焦点确实落到了 body 上，就回落到 crumb 编辑区，而点击"显示隐藏"开关时若发现焦点落在行间，则把焦点同步停靠到开关自身；键盘遍历绝不会落出卡片之外（Modal 没有焦点陷阱），仅 owner 的接纳窗口期间例外——此时 `busy` 把每个控件置为惰性，且对话框反正正在关闭。

 - **导航以选中项为锚、渐进落地。** 在展示根之外（与 crumb 头部渲染的是同一塌缩，因此 crumb 与分栏形态永不相左），browse 客户端的导航在目标层级到达的那一刻即提交它——这次首个落定即关闭编辑器并结束加载，因此 Enter 提交的导航绝不会为等待更多内容而被撤回——随后父层级这一程就地升级这次落地：重新选中目标在父层级中的实际条目（Windows 上按平台惯例折叠大小写），右侧展示其子项，因此 crumb 跳转读作后退一栏，而不是塌缩成单列。父层级这一程在落地的 supersession 范围下运行，任何较新的意图都会在线上将其中止；父层级这一程失败，或被截断的父窗口缺少目标时，都保留已提交的单栏落地——升级的存在正是为了锚定选中项，绝不能反而让它悬空。渐进形态的已知边界：指针按压若恰好落在单个 RTT 的升级窗口内，可能因所按行节点被替换而丢失点击（键盘焦点会重新停靠到重新选中的行上；指针的这段窗口则被接受）；斜杠平台（macOS）上仅末段的大小写偏差会错过父层级条目匹配，保留单栏落地，而祖先段的偏差仍能匹配——父层级条目路径继承键入的前缀——并落地双栏，代价是 Home 塌缩；且导航总是重新列举两程，哪怕目标就是当前展示的层级——crumb 点按兼作刷新手势，因此宁要新鲜度也不复用手头可能已陈旧的列举，代价是至多两次宿主扫描。
 - **符号链接：为可进入性而跟随。** 用 `stat` 探测符号链接（断链／循环→跳过）；面包屑保留操作者导航的逻辑路径，`workspace.create` 在接纳时本就做 realpath 规范化。
 - **列举层级有上限，且流式处理。** 单次 `list` 至多返回 `maxEntries` 行（配置项，默认 1000——GitHub 网页端目录列举的同一上限）。层级经 `opendir` 流入一个按名排序、容量 `maxEntries + 1` 的候选窗口，内存保持 O(maxEntries)，可进入性探测只触及窗口内候选；线上 `DirectoryListing` 携带必填的 `truncated` 标志，让客户端明示不完整而不是静默缺尾。窗口内的断链符号链接不从窗口外回填——发生过驱逐本身已把层级标记为截断。窗口插入为二分查找、满窗尾部单次比较即拒绝（超大层级不能为每个 dirent 付出一次全窗扫描），且 `list(path, signal)` 透传载体的请求信号，滞塞网络目录的扫描不会在调用方断连后继续存活——扫描中的每个 await（打开、每次读取、每次符号链接探测）都与信号赛跑，中止路径放弃而非等待 close（Node 会把 close 排在在飞读取之后），被放弃的 settlement 全部吞掉，清理不会以未处理拒绝的形式冒出。无上限的层级对超大或恶意构造的目录就是内存／响应性漏洞。

If admission blocks or fails, a context-only caller batch takes idle injection's immediate append, while steering and context staged beside it remain available to retry; neither path writes the rejected prompt. When a later prompt is admitted, retained outbox input enters its turn before that prompt, while input accepted during the current admission remains after the prompt. Closing the window before `turn/end` preserves the rule that reentrant late steering becomes an independent queued turn. `Agent.acceptsNextStep` exposes whether a `next-step` send would currently join this window; `status` remains the broader activity signal rather than a routing predicate.

 ## Problem
 
-The Web queue rendered pending messages but could not act on one row. `MessageId` was insufficient as an address because callers may enqueue the same immutable message more than once. The browser also inferred queue retirement from turn and status events, so a row operation racing with driver claim had no authoritative outcome.
-
-“Send now” introduced a separate semantic choice: it could mean reorder the next independent turn, interrupt the current turn as steering, or cancel current work. Only the first interpretation preserves the queue row’s original delivery contract.
+The Web queue rendered pending messages but could not edit or delete one row. `MessageId` was insufficient as an address because callers may enqueue the same immutable message more than once. The browser also inferred queue retirement from turn and status events, so a row operation racing with driver claim had no authoritative outcome.
 
 ## Decision
 
 **Each accepted FIFO occurrence has its own identity.** AgentLoop mints an opaque `InboxItemId` and publishes an `InboxItem` containing that id, the identified `UserMessage`, and its acceptance-time `queued | steering` placement. Reusing one `MessageId` creates distinct inbox identities. Injection bypasses the FIFOs and receives no inbox identity.
 
-**Mutation ends at driver claim.** `Agent.updateInbox(id, action)` synchronously searches the pending queued and steering FIFOs. Edit replaces frozen content while preserving `InboxItemId`, `MessageId`, source, placement, wake policy, and position. Remove emits the occurrence’s terminal discard. Promote moves it to the front of its current FIFO; an ordinary queued item also becomes waking. The driver removes an occurrence before prompt admission or steering drain, so a later mutation returns `not-found` and never rewrites durable history.

Edit replaces frozen content while preserving `InboxItemId`, `MessageId`, source, wake policy, and position. Remove emits the occurrence’s terminal discard. Steering and driver-claimed occurrences return `not-found`, so queue operations never rewrite active-turn input or durable history.
 
-**The live ledger is authoritative.** `agent/inbox/enqueue`, `update`, `dequeue`, and `discard` maintain a Host mirror. The wire sends complete `session/queue` snapshots rather than incremental guesses. Reconnect sends the current baseline, and every live mutation or terminal event replaces it. The client applies no optimistic edit and never retires a row from `turn/start`, `steering/message`, or status changes.

The client applies no optimistic edit and never retires a row from durable turn events or status changes.
 
-**Web actions preserve delivery kind.** QueueDock projects only `queued` occurrences; pending `steering` occurrences remain in the authoritative snapshot but wait for a dedicated Web interaction. It exposes edit and delete, but no send-now control. Edit is available only when all content blocks are text; the editor cannot silently drop non-text blocks. An editing row exposes only save and cancel, with Enter and Escape as their keyboard equivalents. Delete removes the exact occurrence. Protocol-level promotion remains available without being presented as a Web interaction; it never converts queued work into steering or cancels active work.

 **Apply optimistic browser mutations.** Rejected because driver claim and another client can win before the Host action. Waiting for the authoritative snapshot makes the ownership boundary visible and lets `queue-item-not-found` report a real race.
 
-**Treat send-now as steering.** Rejected because it would change a queued independent turn into current-turn context, bypass ordinary prompt admission, and alter the one-send-one-turn guarantee. Promotion changes priority, not delivery semantics.
+**Include pending steering in the queue mutation protocol.** Rejected because QueueDock has no steering interaction, and editing or deleting active-turn input would widen this feature beyond its current consumer. A dedicated steering interaction owns that delivery contract.
 
-**Cancel the active turn before promotion.** Rejected because a row-local action must not destroy unrelated in-flight work.
+**Expose a protocol-only promotion operation.** Rejected because no product interaction reorders Queue. A public operation without a current consumer would add ordering semantics and tests for speculative use.
 
 ## Verification
 
-AgentLoop contract tests hold prompt admission while editing, removing, and promoting exact occurrences, then verify the resulting independent-turn order and terminal lifecycle events. Host schema and proxy tests cover authoritative snapshots, reconnect, typed not-found errors, and the RPC transport. Client runtime and QueueDock tests cover non-optimistic projection, queued-only Web projection, text-only editing, save and cancel affordances, removal, retirement races, disabled mixed-content editing, and the absent send-now control. Keyless browser scenarios drive the exposed edit and delete actions and keep accepted pending steering hidden until it becomes a durable transcript event through the built Web composition and real HTTP/SSE wire.

 ## Consequences
 
-Pending work gains precise row operations without becoming durable session history. Occurrence identity is a live process-local capability and disappears at claim, cancellation, disposal, or restart; reconnect recovers only items still held by the live Agent. Send-now is intentionally weaker than interruption, and editing intentionally excludes mixed content until an editor can preserve every block.
+Queued work gains precise row operations without becoming durable session history. Occurrence identity is a live process-local capability and disappears at claim, cancellation, disposal, or restart; reconnect recovers only queued items still held by the live Agent. Editing excludes mixed content until an editor can preserve every block, while pending steering remains outside this operation surface.
 
 The protocol now carries full queue snapshots on each change. Queues are expected to remain short, so deterministic recovery and multi-client convergence are preferred over an incremental mutation protocol.

 ## 问题
 
-Web 队列能够渲染待处理消息，但无法操作其中某一行。`MessageId` 不足以充当寻址标识，因为调用方可以多次将同一条不可变消息加入队列。浏览器还会根据轮次和状态事件推断队列项已退役，因此当行操作与驱动器认领发生竞态时，系统无法给出权威结果。

-“立即发送”还引入了另一项语义选择：它可以表示重新排序下一个独立轮次、以 steering（中途引导）方式打断当前轮次，或取消当前工作。只有第一种解释能够保留该队列行原有的投递契约。

 ## 后果
 
-待处理工作获得精确的行操作，但不会因此成为持久会话历史。单次入队标识是进程本地的实时寻址凭据，会在认领、取消、dispose 或重启时消失；重连只能恢复仍由活跃 Agent 持有的项。立即发送有意弱于打断，而编辑也有意排除混合内容，直至编辑器能够保留每个块。

 现在，协议会在每次变更时携带完整队列快照。队列预期保持较短，因此系统优先选择确定性恢复和多客户端收敛，而非增量变更协议。

 The unified `send()` primitive routes content and source by (`target` × `wakeup`); `followup`/`steer`/`inject` are its fixed-preset aliases. A `next-turn` item joins the queued FIFO, waking the driver unless `wakeup: false`; admission happens before any turn opens. The loop opens a private next-step acceptance window before `agent/prompt-submit` and closes it before `turn/end`. During that window, `steer()` and `inject()` stage in one outbox; an allowed admission opens the turn, records the prompt and returned `additionalContexts`, then drains the staged input before the first request. A blocked or failed admission writes no prompt or hook-produced context. A caller-staged context-only batch then takes idle injection's immediate append, while steering and context staged beside it remain pending for retry or a later admitted prompt. Outside the window, steering becomes a waking queued prompt and injection immediately appends `user/message` without opening a turn or running the model.
 
-Every FIFO acceptance mints an `InboxItemId` and publishes `agent/inbox/enqueue` with the complete occurrence. `updateInbox()` owns the synchronous pending-item boundary: edit freezes replacement content without changing message identity or position, remove publishes discard, and promote moves the occurrence to the head of its queued or steering FIFO; promoting queued work also makes it waking. Edit and promote publish `agent/inbox/update`. Claim publishes `agent/inbox/dequeue` and irrevocably removes the live address before prompt admission, so a racing update returns `not-found`; `cancel()` without `keepInbox` publishes `agent/inbox/discard`.

 The handle every plugin programs against:
 
 - `agent.send(message, options)` — the one delivery primitive over the (`target` × `wakeup`) matrix. `message` is an already identified, frozen `UserMessage`; callers normally create it with `createUserMessage()` before routing begins. `SendOptions` owns only the `target` and `wakeup` policy. Each accepted FIFO occurrence receives its own `InboxItemId`, even when callers reuse a `MessageId`; `agent/inbox/enqueue`/`update` and the terminal `dequeue` or `discard` carry that complete `InboxItem`. `target: 'next-turn'` queues one independent FIFO item that, if admitted, becomes the sole ordinary prompt in its turn. `target: 'next-step'` with `wakeup: true` submits steering, while `target: 'next-step'` with `wakeup: false` injects durable context without running the model. The [one-send-one-turn Agent Note](../../../.agents/notes/implemented/simplification/2026-07-17-one-send-one-turn.md) owns the turn rationale.
-- `agent.updateInbox(itemId, action)` — synchronously edits, removes, or promotes one still-pending occurrence. Edit keeps its `MessageId`, `InboxItemId`, source, placement, and FIFO position while replacing frozen content. Remove emits the occurrence's terminal discard. Promote moves it to the front of its current FIFO and makes an ordinary queued item waking. A claimed item has crossed the ownership boundary and returns `not-found`.
+- `agent.updateInbox(itemId, action)` — synchronously edits or removes one still-pending queued occurrence. Edit keeps its `MessageId`, `InboxItemId`, source, and FIFO position while replacing frozen content; remove emits the occurrence's terminal discard. Steering and claimed occurrences return `not-found`.
 - `agent.followup(input)` — the `next-turn`/wakeup preset of `send()`: queue an ordinary follow-up turn and wake the driver.
 - `agent.steer(input)` — the `next-step`/wakeup preset: during prompt admission or an open turn, stage steering for the next safe boundary without dispatching `agent/prompt-submit`; outside that acceptance window, delegate to a woken follow-up. Admission failure leaves staged steering for retry or a later admitted prompt, while cancellation or disposal may discard it.
 - `agent.inject(input)` — the `next-step`/no-wakeup preset: append model-facing context without running the model; the next request sees a verbatim user-role message whose provenance is carried by the required `input.source`. During prompt admission or an open turn, injection waits in the outbox for the next safe boundary. Outside that acceptance window, it appends immediately without opening a turn; a context-only admission batch takes this fallback if admission closes without a turn, while context staged beside steering remains pending with it. Persistence reacts to `session/event` independently. Injection emits no `agent/inbox/*` event.

 每个插件面向的 handle：
 
 - `agent.send(message, options)`：覆盖（`target` × `wakeup`）矩阵的唯一投递原语。`message` 是已有标识且已冻结的 `UserMessage`；调用方通常会在开始路由前使用 `createUserMessage()` 创建它。`SendOptions` 只持有 `target` 与 `wakeup` 策略。每次获准进入 FIFO 的项都会获得独立的 `InboxItemId`，即使调用方复用了同一个 `MessageId`；`agent/inbox/enqueue`／`update` 及终态 `dequeue` 或 `discard` 都会携带这一完整 `InboxItem`。`target: 'next-turn'` 排队一条独立 FIFO 项，获准后成为其轮次中唯一的普通提示词。`target: 'next-step'` 且 `wakeup: true` 提交 steering（中途引导），而 `target: 'next-step'` 且 `wakeup: false` 注入持久上下文，不运行模型。轮次原理由 [one-send-one-turn Agent Note](../../../.agents/notes/implemented/simplification/2026-07-17-one-send-one-turn.md)拥有。
-- `agent.updateInbox(itemId, action)`：同步编辑、移除或前移一个仍处于待处理状态的项。编辑会替换已冻结的内容，同时保留其 `MessageId`、`InboxItemId`、来源、放置方式与 FIFO 位置。移除会发出该项的终态 discard。前移会把它移至当前 FIFO 的队首，并使普通 queued 项能够唤醒驱动器。已被认领的项已经跨越所有权边界，因此返回 `not-found`。

 - `agent.followup(input)`：`send()` 的 `next-turn`／wakeup 预设：排队一个普通后续轮次并唤醒驱动器。
 - `agent.steer(input)`：`next-step`／wakeup 预设：提示词接纳期间或轮次打开时，为下一个安全边界暂存 steering，且不分发 `agent/prompt-submit`；该接收窗口之外则委托给会唤醒的后续轮次。接纳失败会保留暂存的 steering，以供重试或之后获准的提示词使用，而取消或 dispose 可能丢弃它。
 - `agent.inject(input)`：`next-step`／不唤醒预设：追加面向模型的上下文而不运行模型；下一次请求会看到一条逐字的 user role 消息，其来源由必填的 `input.source` 携带。提示词接纳期间或轮次打开时，注入会在 outbox 中等待下一个安全边界。该接收窗口之外，它会立即追加而不开启轮次；如果接纳结束却未开启轮次，仅含上下文的接纳批次会采用这一回退，而与 steering 一同暂存的上下文则会随其继续待处理。持久化独立地响应 `session/event`。注入不发出 `agent/inbox/*` 事件。

 Session model routing is a session-domain contract. `session.models` returns the selected provider/model/reasoning target with provider-grouped advisory models, exact-route reasoning metadata, and provider-local lookup failures. `session.selectModel` validates the optional adapter-owned reasoning effort and replaces the complete target selected for the next prompt-assembly boundary. Catalog membership is not validation: an adapter may resolve an unlisted model, while an unavailable route or unsupported effort returns `model-unavailable`.
 
-Pending agent input is a live control-plane contract, not session history. The gateway mirrors complete `InboxItem` occurrences from `agent/inbox/*` and broadcasts authoritative `session/queue` snapshots on every change and reconnect. `session.updateQueue` addresses one `InboxItemId`: edit replaces pending content, remove discards it, and promote moves it to the front of its current FIFO while waking ordinary queued work. A driver claim wins races by retiring the address before admission; a later operation returns `queue-item-not-found`. The client never infers retirement from turn or status events.
+Pending queued input is a live control-plane contract, not session history.

A driver claim wins races by retiring the address before admission; a later operation returns `queue-item-not-found`. The client never infers retirement from turn or status events.
 
 Workspace and Session lists are separate reconnect baselines. `workspace.create` creates a unique name or adopts an existing directory, `workspace.delete` removes only the Workspace registration, `session.create` accepts an optional preallocated Session id, and `host/workspace-changed`, `host/workspace-removed`, plus `host/session-added` carry committed increments in either arrival order. Registration deletion preserves the directory and session logs; its Sessions remain in `session.list` and become Ungrouped. `SessionSummary.blank` and the `host/session-added` frame carry the derived zero-events bit: clients hide blank sessions and reuse them per workspace, flip blank on the first `host/session-status(running:true)`, and treat `session.list` as the reconnect authority; cold summaries are never blank because lazy persistence keeps never-appended sessions out of `list()`.

@@ -22,6 +22,7 @@ Placement and policy rulings folded into this decision:
 - **Path-editor cancel scope: the dialog card.** The browse client's path editor cancels on Escape and on focus leaving the card, both observed at a card-scope wrapper rather than the input — after Tab parks focus on a filtered row the input is off the event path, yet Escape must collapse the editor (not the dialog) and a later focus departure must still cancel. Non-cancel exemptions: window/tab focus loss, in-card focus moves, and pointer paths (rows and the toggle suppress focus steal on mousedown while editing). Separators for seeding and draft-tail filtering are read from the host-resolved root crumb (exact for every root form this backend emits: `/`, `C:\`, `\\server\share\`); the wire-field alternative below records the deferred authoritative form. Combobox semantics between the editor and the list it filters (`aria-expanded`/`aria-controls`/active-descendant, result announcements) are likewise deferred — today they read to assistive tech as separate widgets. Focus parking is a card-wide invariant, not an editor-only one: every pick — editing or not, including right-pane advances and create landings whose columns are replaced — re-parks focus on the selection's row after commit, while every other displacing exit (Enter, Escape, a navigation landing whose new level dropped the focused row, a failed pick or create relist, and the nested create dialog closing) falls back to the crumb edit zone whenever focus actually fell to body, and a show-hidden toggle click that finds focus among the rows parks synchronously on the toggle itself. The guarantee is scoped to the dialog's own node replacements — the Modal has no focus trap, so tabbing past the card's edge legitimately leaves, and the owner's adopt window (where `busy` inerts every control and the dialog is closing either way) is likewise outside it.
 - **Navigation lands selection-anchored, progressively.** Away from the display root (the same collapse the crumb header renders, so crumbs and pane shape never disagree), the browse client's navigate commits the target level the moment it arrives — the editor closes and loading ends on that first settlement, so an Enter-submitted navigation is never withdrawn waiting on more — and a parent leg then upgrades the landing in place: the target's actual parent-level entry re-selected (platform case folding on Windows), its children on the right, so a crumb jump reads as stepping back one pane rather than collapsing to a single column. The parent leg runs under the landing's supersession scope and is aborted on the wire by any newer intent; a failed parent leg, or a truncated parent window lacking the target, leaves the committed single-pane landing — the upgrade must never orphan the selection it exists to anchor. Known boundaries of the progressive shape: a pointer press landing exactly inside the one-RTT upgrade window can lose its click when the pressed row node is replaced (keyboard focus is re-parked on the re-selected row; the pointer window is accepted); on slash platforms (macOS) only a final-segment case drift misses the parent-entry match and keeps the single-pane landing, while ancestor-segment drift still matches — parent entry paths inherit the typed prefix — and lands two panes at the cost of the Home collapse; and navigate always relists both legs even when the target is the currently shown level — a crumb tap doubles as the refresh gesture, so freshness wins over reusing possibly-stale in-hand listings at the cost of up to two host scans.
 - **Symlinks: follow for enterability.** `stat` probes symlinks (broken/cyclic → skipped); crumbs keep the logical path the operator navigated, and `workspace.create` already canonicalizes via realpath at adoption.
+- **One canonical path shape on the wire.** A listing's `path`, `crumbs[].path`, `entries[].path`, and `home` all ship host-resolved — homedir() output included, since the environment may decorate HOME and the backend resolves it before stamping. Clients compare listing paths verbatim on that promise; the only lexical mirror left in the browse client serves the draft side, the one path a user types and hence naturally non-canonical. Normalizing at the source replaces a client-side mirror of resolve() that had to anticipate every decoration (trailing and repeated separators, dot segments, UNC roots, forward slashes), and the promise binds every browse backend.
 - **Listing levels are bounded, and streamed.** One `list` call returns at most `maxEntries` rows (config, default 1000 — GitHub's web-UI directory-listing bound). The level streams via `opendir` into a name-sorted window of `maxEntries + 1` candidates, so memory stays O(maxEntries) and enterability probing touches only windowed candidates; the wire `DirectoryListing` carries a required `truncated` flag so the client states incompleteness instead of silently missing tail entries. A windowed broken symlink is not backfilled from beyond the window — the eviction already marks the level truncated. Window insertion is binary with an O(1) full-window tail rejection (an oversized level must not pay a window scan per dirent), and `list(path, signal)` threads the carrier's request signal so a scan of a stalled network directory cannot outlive a disconnected caller — every await in the scan (open, each read, each symlink probe) races the signal, an aborted exit abandons rather than awaits the close (Node queues close behind in-flight reads), and abandoned settlements are swallowed so cleanup can never surface as an unhandled rejection. An unbounded level is a memory/responsiveness hole for large or adversarial directories.
 - **Whole-filesystem scope, no roots config.** `workspace.create` accepts arbitrary paths and the API serves bash-driving methods, so a browse root would be UX scoping, not a boundary; configurability without a consumer fails the evidence bar. Deferred until a deployment needs it.
 - **The native backend stays.** Plugin-form was the point: multiple providers can serve the seam (an Electron shell would provide the `native` interaction through its own dialog API). Kind naming: `dialog` was the first pick and was dropped — the browse interaction also presents a dialog (the in-app modal), so the word failed to discriminate; `native` names where the chooser runs.

 - **路径编辑器的取消范围：对话框卡片。** browse 客户端的路径编辑器在按 Escape 与焦点离开卡片时取消，两者都在卡片范围的包装层而非输入框上监听——Tab 把焦点停到某个过滤命中的行之后，输入框已不在事件路径上，但 Escape 仍须收起编辑器（而非对话框），其后的焦点离开也仍须取消。不取消的豁免：窗口／标签页失焦、卡片内焦点移动，以及指针路径（编辑期间行与开关在 mousedown 时抑制焦点夺取）。预填与草稿末段过滤所用的分隔符从宿主解析的根 crumb 读取（对该后端发出的每种根形态都精确：`/`、`C:\`、`\\server\share\`）；下文的线上字段替代方案记录了被延期的权威形态。编辑器与其过滤的列表之间的 combobox 语义（`aria-expanded`／`aria-controls`／active-descendant、结果播报）同样被延期——目前二者在辅助技术看来是彼此独立的控件。焦点停靠是卡片全域的不变量，而非编辑器独有：每次选取——无论是否处于编辑态，包括右栏推进与各列被替换的创建落地——提交后都把焦点重新停靠到选中项所在的行上，而其余所有会顶离焦点的退出（Enter、Escape、新层级已不含焦点所在行的导航落地、选取或创建失败后的重新列举，以及嵌套创建对话框的关闭）只要焦点确实落到了 body 上，就回落到 crumb 编辑区，而点击"显示隐藏"开关时若发现焦点落在行间，则把焦点同步停靠到开关自身。该保证的范围仅限对话框自身的节点替换——Modal 没有焦点陷阱，所以 Tab 越过卡片边缘属于正当离开，而 owner 的接纳窗口（其间 `busy` 把每个控件置为惰性，且对话框反正正在关闭）同样在此范围之外。
 - **导航以选中项为锚、渐进落地。** 在展示根之外（与 crumb 头部渲染的是同一塌缩，因此 crumb 与分栏形态永不相左），browse 客户端的导航在目标层级到达的那一刻即提交它——这次首个落定即关闭编辑器并结束加载，因此 Enter 提交的导航绝不会为等待更多内容而被撤回——随后父层级这一程就地升级这次落地：重新选中目标在父层级中的实际条目（Windows 上按平台惯例折叠大小写），右侧展示其子项，因此 crumb 跳转读作后退一栏，而不是塌缩成单列。父层级这一程在落地的 supersession 范围下运行，任何较新的意图都会在线上将其中止；父层级这一程失败，或被截断的父窗口缺少目标时，都保留已提交的单栏落地——升级的存在正是为了锚定选中项，绝不能反而让它悬空。渐进形态的已知边界：指针按压若恰好落在单个 RTT 的升级窗口内，可能因所按行节点被替换而丢失点击（键盘焦点会重新停靠到重新选中的行上；指针的这段窗口则被接受）；斜杠平台（macOS）上仅末段的大小写偏差会错过父层级条目匹配，保留单栏落地，而祖先段的偏差仍能匹配——父层级条目路径继承键入的前缀——并落地双栏，代价是 Home 塌缩；且导航总是重新列举两程，哪怕目标就是当前展示的层级——crumb 点按兼作刷新手势，因此宁要新鲜度也不复用手头可能已陈旧的列举，代价是至多两次宿主扫描。
 - **符号链接：为可进入性而跟随。** 用 `stat` 探测符号链接（断链／循环→跳过）；面包屑保留操作者导航的逻辑路径，`workspace.create` 在接纳时本就做 realpath 规范化。
+- **线上只有一种规范路径形态。** 列举的 `path`、`crumbs[].path`、`entries[].path` 与 `home` 一律以宿主解析后的形态发出——homedir() 的输出也不例外，因为环境可能修饰 HOME，后端在标注前先行解析。客户端凭这一承诺逐字比较列举路径；browse 客户端仅剩的词法镜像服务于草稿一侧——用户键入的那一条路径，因而天然非规范。在源头做规范化，取代了客户端侧那份必须预判每种修饰（末尾与重复的分隔符、点段、UNC 根、正斜杠）的 resolve() 镜像，且这一承诺约束每一个 browse 后端。
 - **列举层级有上限，且流式处理。** 单次 `list` 至多返回 `maxEntries` 行（配置项，默认 1000——GitHub 网页端目录列举的同一上限）。层级经 `opendir` 流入一个按名排序、容量 `maxEntries + 1` 的候选窗口，内存保持 O(maxEntries)，可进入性探测只触及窗口内候选；线上 `DirectoryListing` 携带必填的 `truncated` 标志，让客户端明示不完整而不是静默缺尾。窗口内的断链符号链接不从窗口外回填——发生过驱逐本身已把层级标记为截断。窗口插入为二分查找、满窗尾部单次比较即拒绝（超大层级不能为每个 dirent 付出一次全窗扫描），且 `list(path, signal)` 透传载体的请求信号，滞塞网络目录的扫描不会在调用方断连后继续存活——扫描中的每个 await（打开、每次读取、每次符号链接探测）都与信号赛跑，中止路径放弃而非等待 close（Node 会把 close 排在在飞读取之后），被放弃的 settlement 全部吞掉，清理不会以未处理拒绝的形式冒出。无上限的层级对超大或恶意构造的目录就是内存／响应性漏洞。
 - **全盘可浏览，不做 roots 配置。** `workspace.create` 接受任意路径且 API 本就提供驱动 bash 的方法，浏览根只会是 UX 范围而非边界；没有消费方的可配置性过不了证据门槛。等到有部署需要再做。
 - **native 后端保留。** 插件化正是目的：多方都能提供该 seam（Electron 壳可以经自己的对话框 API 提供 `native` 交互）。kind 命名：最初选了 `dialog` 后被放弃——browse 交互同样以对话框呈现（应用内弹窗），这个词起不到判别作用；`native` 命名的是选择器运行的位置。

 The **workspace-directory picking seam** for the web-GUI host: an abstract `DirectoryPicker` service (`ctx.directoryPicker`) whose single contract method `capability()` returns a discriminated capability describing how an operator selects a directory. Backends differ in interaction shape, not just mechanism, so the seam models the shapes explicitly instead of one method set: `{ kind: 'native', pick(signal) }` opens one native OS chooser on the host display ([`-native`](../directory-picker-native/README.md)); `{ kind: 'browse', list(path?), createDirectory(path, name) }` serves listing/creation primitives an in-app browser drives, which works for remote clients no OS chooser can reach ([`-browse`](../directory-picker-browse/README.md)). Consumers switch on `capability().kind`; the union derives from the merge-extensible `DirectoryPickerCapabilities` map (a new backend declaration-merges its shape there), and the documented default for an unknown kind is to hide the picking affordance rather than fail. The capability object must be stable for the service lifetime. The client side mirrors the seam without a wire advertisement: each backend package is dual-face, its browser half registering the matching picking interaction into ui-workspace's directory-flow slots — so one composition row swaps both the host capability and the client flow together.
 
-Browse primitives fail with the typed `DirectoryPickerError` (`directory-unreadable` / `directory-exists` / `directory-create-failed`, each carrying the subject `path`), which the consuming gateway maps 1:1 onto wire error codes. `DirectoryEntry` rows carry a host-owned `hidden` flag (POSIX dot convention) so display policy stays client-side; `DirectoryListing.crumbs` is the ancestor chain from the filesystem root, every crumb a jump target. Design rationale, the `ctx.fs` separation, and the policy decisions live in [the directory-picker capability seam Agent Note](../../../.agents/notes/implemented/architecture/2026-07-28-directory-picker-capability-seam.md).
+Browse primitives fail with the typed `DirectoryPickerError` (`directory-unreadable` / `directory-exists` / `directory-create-failed`, each carrying the subject `path`), which the consuming gateway maps 1:1 onto wire error codes. `DirectoryEntry` rows carry a host-owned `hidden` flag (POSIX dot convention) so display policy stays client-side; `DirectoryListing.crumbs` is the ancestor chain from the filesystem root, every crumb a jump target. Every path in one listing — and `createDirectory`'s returned path — ships in host-resolved canonical shape (lexical `resolve()`, never realpath): clients compare listing paths verbatim, so every backend must resolve before stamping. Design rationale, the `ctx.fs` separation, and the policy decisions live in [the directory-picker capability seam Agent Note](../../../.agents/notes/implemented/architecture/2026-07-28-directory-picker-capability-seam.md).

@@ -22,7 +22,7 @@ Placement and policy rulings folded into this decision:
 - **Path-editor cancel scope: the dialog card.** The browse client's path editor cancels on Escape and on focus leaving the card, both observed at a card-scope wrapper rather than the input — after Tab parks focus on a filtered row the input is off the event path, yet Escape must collapse the editor (not the dialog) and a later focus departure must still cancel. Non-cancel exemptions: window/tab focus loss, in-card focus moves, and pointer paths (rows and the toggle suppress focus steal on mousedown while editing). Separators for seeding and draft-tail filtering are read from the host-resolved root crumb (exact for every root form this backend emits: `/`, `C:\`, `\\server\share\`); the wire-field alternative below records the deferred authoritative form. Combobox semantics between the editor and the list it filters (`aria-expanded`/`aria-controls`/active-descendant, result announcements) are likewise deferred — today they read to assistive tech as separate widgets. Focus parking is a card-wide invariant, not an editor-only one: every pick — editing or not, including right-pane advances and create landings whose columns are replaced — re-parks focus on the selection's row after commit, while every other displacing exit (Enter, Escape, a navigation landing whose new level dropped the focused row, a failed pick or create relist, and the nested create dialog closing) falls back to the crumb edit zone whenever focus actually fell to body, and a show-hidden toggle click that finds focus among the rows parks synchronously on the toggle itself. The guarantee is scoped to the dialog's own node replacements — the Modal has no focus trap, so tabbing past the card's edge legitimately leaves, and the owner's adopt window (where `busy` inerts every control and the dialog is closing either way) is likewise outside it.
 - **Navigation lands selection-anchored, progressively.** Away from the display root (the same collapse the crumb header renders, so crumbs and pane shape never disagree), the browse client's navigate commits the target level the moment it arrives — the editor closes and loading ends on that first settlement, so an Enter-submitted navigation is never withdrawn waiting on more — and a parent leg then upgrades the landing in place: the target's actual parent-level entry re-selected (platform case folding on Windows), its children on the right, so a crumb jump reads as stepping back one pane rather than collapsing to a single column. The parent leg runs under the landing's supersession scope and is aborted on the wire by any newer intent; a failed parent leg, or a truncated parent window lacking the target, leaves the committed single-pane landing — the upgrade must never orphan the selection it exists to anchor. Known boundaries of the progressive shape: a pointer press landing exactly inside the one-RTT upgrade window can lose its click when the pressed row node is replaced (keyboard focus is re-parked on the re-selected row; the pointer window is accepted); on slash platforms (macOS) only a final-segment case drift misses the parent-entry match and keeps the single-pane landing, while ancestor-segment drift still matches — parent entry paths inherit the typed prefix — and lands two panes at the cost of the Home collapse; and navigate always relists both legs even when the target is the currently shown level — a crumb tap doubles as the refresh gesture, so freshness wins over reusing possibly-stale in-hand listings at the cost of up to two host scans.
 - **Symlinks: follow for enterability.** `stat` probes symlinks (broken/cyclic → skipped); crumbs keep the logical path the operator navigated, and `workspace.create` already canonicalizes via realpath at adoption.
-- **One canonical path shape on the wire.** A listing's `path`, `crumbs[].path`, `entries[].path`, and `home` all ship host-resolved — homedir() output included, since the environment may decorate HOME and the backend resolves it before stamping. Clients compare listing paths verbatim on that promise; the only lexical mirror left in the browse client serves the draft side, the one path a user types and hence naturally non-canonical. Normalizing at the source replaces a client-side mirror of resolve() that had to anticipate every decoration (trailing and repeated separators, dot segments, UNC roots, forward slashes), and the promise binds every browse backend.
+- **One canonical path shape on the wire.** A listing's `path`, `crumbs[].path`, `entries[].path`, and `home` — and `createDirectory`'s returned path, which clients compare verbatim against the child's next `entries[].path` to anchor the create landing — all ship host-resolved: lexical `resolve()`, never realpath (the symlink ruling above keeps ancestries logical), with homedir() output included since the environment may decorate HOME and the backend resolves it before stamping. Clients compare listing paths verbatim on that promise; the only lexical mirror left in the browse client serves the draft side, the one path a user types and hence naturally non-canonical. Normalizing at the source replaces a client-side mirror of resolve() that had to anticipate every decoration (trailing and repeated separators, dot segments, UNC roots, forward slashes), and the promise binds every browse backend.
 - **Listing levels are bounded, and streamed.** One `list` call returns at most `maxEntries` rows (config, default 1000 — GitHub's web-UI directory-listing bound). The level streams via `opendir` into a name-sorted window of `maxEntries + 1` candidates, so memory stays O(maxEntries) and enterability probing touches only windowed candidates; the wire `DirectoryListing` carries a required `truncated` flag so the client states incompleteness instead of silently missing tail entries. A windowed broken symlink is not backfilled from beyond the window — the eviction already marks the level truncated. Window insertion is binary with an O(1) full-window tail rejection (an oversized level must not pay a window scan per dirent), and `list(path, signal)` threads the carrier's request signal so a scan of a stalled network directory cannot outlive a disconnected caller — every await in the scan (open, each read, each symlink probe) races the signal, an aborted exit abandons rather than awaits the close (Node queues close behind in-flight reads), and abandoned settlements are swallowed so cleanup can never surface as an unhandled rejection. An unbounded level is a memory/responsiveness hole for large or adversarial directories.
 - **Whole-filesystem scope, no roots config.** `workspace.create` accepts arbitrary paths and the API serves bash-driving methods, so a browse root would be UX scoping, not a boundary; configurability without a consumer fails the evidence bar. Deferred until a deployment needs it.
 - **The native backend stays.** Plugin-form was the point: multiple providers can serve the seam (an Electron shell would provide the `native` interaction through its own dialog API). Kind naming: `dialog` was the first pick and was dropped — the browse interaction also presents a dialog (the in-app modal), so the word failed to discriminate; `native` names where the chooser runs.

 - **路径编辑器的取消范围：对话框卡片。** browse 客户端的路径编辑器在按 Escape 与焦点离开卡片时取消，两者都在卡片范围的包装层而非输入框上监听——Tab 把焦点停到某个过滤命中的行之后，输入框已不在事件路径上，但 Escape 仍须收起编辑器（而非对话框），其后的焦点离开也仍须取消。不取消的豁免：窗口／标签页失焦、卡片内焦点移动，以及指针路径（编辑期间行与开关在 mousedown 时抑制焦点夺取）。预填与草稿末段过滤所用的分隔符从宿主解析的根 crumb 读取（对该后端发出的每种根形态都精确：`/`、`C:\`、`\\server\share\`）；下文的线上字段替代方案记录了被延期的权威形态。编辑器与其过滤的列表之间的 combobox 语义（`aria-expanded`／`aria-controls`／active-descendant、结果播报）同样被延期——目前二者在辅助技术看来是彼此独立的控件。焦点停靠是卡片全域的不变量，而非编辑器独有：每次选取——无论是否处于编辑态，包括右栏推进与各列被替换的创建落地——提交后都把焦点重新停靠到选中项所在的行上，而其余所有会顶离焦点的退出（Enter、Escape、新层级已不含焦点所在行的导航落地、选取或创建失败后的重新列举，以及嵌套创建对话框的关闭）只要焦点确实落到了 body 上，就回落到 crumb 编辑区，而点击"显示隐藏"开关时若发现焦点落在行间，则把焦点同步停靠到开关自身。该保证的范围仅限对话框自身的节点替换——Modal 没有焦点陷阱，所以 Tab 越过卡片边缘属于正当离开，而 owner 的接纳窗口（其间 `busy` 把每个控件置为惰性，且对话框反正正在关闭）同样在此范围之外。
 - **导航以选中项为锚、渐进落地。** 在展示根之外（与 crumb 头部渲染的是同一塌缩，因此 crumb 与分栏形态永不相左），browse 客户端的导航在目标层级到达的那一刻即提交它——这次首个落定即关闭编辑器并结束加载，因此 Enter 提交的导航绝不会为等待更多内容而被撤回——随后父层级这一程就地升级这次落地：重新选中目标在父层级中的实际条目（Windows 上按平台惯例折叠大小写），右侧展示其子项，因此 crumb 跳转读作后退一栏，而不是塌缩成单列。父层级这一程在落地的 supersession 范围下运行，任何较新的意图都会在线上将其中止；父层级这一程失败，或被截断的父窗口缺少目标时，都保留已提交的单栏落地——升级的存在正是为了锚定选中项，绝不能反而让它悬空。渐进形态的已知边界：指针按压若恰好落在单个 RTT 的升级窗口内，可能因所按行节点被替换而丢失点击（键盘焦点会重新停靠到重新选中的行上；指针的这段窗口则被接受）；斜杠平台（macOS）上仅末段的大小写偏差会错过父层级条目匹配，保留单栏落地，而祖先段的偏差仍能匹配——父层级条目路径继承键入的前缀——并落地双栏，代价是 Home 塌缩；且导航总是重新列举两程，哪怕目标就是当前展示的层级——crumb 点按兼作刷新手势，因此宁要新鲜度也不复用手头可能已陈旧的列举，代价是至多两次宿主扫描。
 - **符号链接：为可进入性而跟随。** 用 `stat` 探测符号链接（断链／循环→跳过）；面包屑保留操作者导航的逻辑路径，`workspace.create` 在接纳时本就做 realpath 规范化。

 - **全盘可浏览，不做 roots 配置。** `workspace.create` 接受任意路径且 API 本就提供驱动 bash 的方法，浏览根只会是 UX 范围而非边界；没有消费方的可配置性过不了证据门槛。等到有部署需要再做。

 ## Known Limitations and Deferred Work
 
 - **Windows hidden attribute is not read** — Node dirents do not expose `FILE_ATTRIBUTE_HIDDEN`, so `hidden` means dot-prefixed on every platform until a native probe is worth its cost.
+- **Name-normalizing volumes void the create-path equality** — `createDirectory` promises its return verbatim-equal to the child's next `entries[].path`; Node's namespaced Win32 paths store even trailing-dot/space segments literally, but a volume that rewrites names on storage (NFD normalization on HFS+-style volumes) breaks the match, and the create landing degrades to the documented single-pane / edit-zone fallback.
 - **No drive-root enumeration** — on Windows the ancestry stops at the drive root; crossing drives waits for the browser UI's path-entry affordance rather than an enumeration primitive here.
 - **Whole-filesystem scope** — no per-deployment browse-root restriction; `workspace.create` accepts arbitrary paths today, so a root here would be UX scoping, not a boundary — deferred until a deployment needs it.

 ## 已知限制与延期工作
 
 - **不读取 Windows 隐藏属性**——Node 的 dirent 不暴露 `FILE_ATTRIBUTE_HIDDEN`，因此在所有平台上 `hidden` 都意味着点前缀，直到原生探测值回其成本为止。
+- **名称规范化的卷会使创建路径等式失效**——`createDirectory` 承诺其返回值与该子项下一次的 `entries[].path` 逐字相等；Node 带命名空间的 Win32 路径连末尾点／空格段都按字面存储，但在存储时改写名称的卷（HFS+ 风格卷上的 NFD 规范化）会破坏这一匹配，创建落地随之退化为文档所述的单栏／编辑区回退。

 ## Known Limitations and Deferred Work
 
 - **Windows hidden attribute is not read** — Node dirents do not expose `FILE_ATTRIBUTE_HIDDEN`, so `hidden` means dot-prefixed on every platform until a native probe is worth its cost.
-- **Name-normalizing volumes void the create-path equality** — `createDirectory` promises its return verbatim-equal to the child's next `entries[].path`; Node's namespaced Win32 paths store even trailing-dot/space segments literally, but a volume that rewrites names on storage (NFD normalization on HFS+-style volumes) breaks the match, and the create landing degrades to the documented single-pane / edit-zone fallback.

 - **No drive-root enumeration** — on Windows the ancestry stops at the drive root; crossing drives waits for the browser UI's path-entry affordance rather than an enumeration primitive here.
 - **Whole-filesystem scope** — no per-deployment browse-root restriction; `workspace.create` accepts arbitrary paths today, so a root here would be UX scoping, not a boundary — deferred until a deployment needs it.

 ## 已知限制与延期工作
 
 - **不读取 Windows 隐藏属性**——Node 的 dirent 不暴露 `FILE_ATTRIBUTE_HIDDEN`，因此在所有平台上 `hidden` 都意味着点前缀，直到原生探测值回其成本为止。
-- **名称规范化的卷会使创建路径等式失效**——`createDirectory` 承诺其返回值与该子项下一次的 `entries[].path` 逐字相等；Node 带命名空间的 Win32 路径连末尾点／空格段都按字面存储，但在存储时改写名称的卷（HFS+ 风格卷上的 NFD 规范化）会破坏这一匹配，创建落地随之退化为文档所述的单栏／编辑区回退。

 ## Verification

Host schema and proxy tests cover queued-only authoritative snapshots, reconnect, typed not-found errors, and the RPC transport. Client runtime and QueueDock tests cover non-optimistic projection, text-only editing, save and cancel affordances, removal, retirement races, and disabled mixed-content editing. Keyless browser scenarios drive the exposed edit and delete actions through the built Web composition and real HTTP/SSE wire.

 Workspace and Session lists are separate reconnect baselines. `workspace.create` creates a unique name or adopts an existing directory, `workspace.delete` removes only the Workspace registration, `session.create` accepts an optional preallocated Session id, and `host/workspace-changed`, `host/workspace-removed`, plus `host/session-added` carry committed increments in either arrival order. Registration deletion preserves the directory and session logs; its Sessions remain in `session.list` and become Ungrouped. `SessionSummary.blank` and the `host/session-added` frame carry the derived zero-events bit: clients hide blank sessions and reuse them per workspace, flip blank on the first `host/session-status(running:true)`, and treat `session.list` as the reconnect authority; cold summaries are never blank because lazy persistence keeps never-appended sessions out of `list()`.

 会话模型路由属于会话领域契约。`session.models` 返回选中的提供方／模型／推理（reasoning）目标，以及按提供方分组的建议性模型、精确路由推理元数据和逐提供方查询失败记录。`session.selectModel` 校验由适配器持有的可选推理强度，并替换将在下一提示词组装边界使用的完整目标。目录成员关系不构成校验：适配器可以解析未列出的模型，而不可用路由或不受支持的推理强度会返回 `model-unavailable`。

 Workspace 列表与 Session 列表是相互独立的重连基线。`workspace.create` 会创建唯一名称或接纳现有目录，`workspace.delete` 只移除 Workspace 注册记录，`session.create` 接受可选的预分配 Session id，`host/workspace-changed`、`host/workspace-removed` 与 `host/session-added` 则以任意到达顺序携带已提交的增量。删除注册记录会保留目录和会话日志；相关 Session 仍留在 `session.list` 中，并进入 Ungrouped。`SessionSummary.blank` 与 `host/session-added` 帧携带派生的零事件位：客户端隐藏空白会话并按 workspace 复用它们，在首个 `host/session-status(running:true)` 时翻转 blank，并以 `session.list` 作为重连权威；冷会话摘要永远不是空白：惰性持久化让从未追加过事件的会话根本不出现在 `list()` 中。

Subject: [PATCH 153/212] revert: restore the reviewer-approved tree
 (97a192d7b)

ZiyaZhang approved 97a192d7b; the subsequent bot-review rounds (7-24)
landed after that approval and were not requested by a human reviewer.
This commit restores the approved tree verbatim as a forward commit
(pushed history stays intact). git diff 97a192d7b is empty.

@@ -19,10 +19,9 @@ Placement and policy rulings folded into this decision:
 - **Not the `ctx.fs` seam.** `packages/fs/` is the model/session-facing storage stack (policy events, sandbox-swappable backends). Riding it would couple GUI browsing to the model's confinement backend — swapping `fs-sandbox` for the model must never change GUI behavior — and OS facts (home anchoring, hidden conventions) are not storage primitives. The picker seam stays presentation-free and model-free; `packages/host/` is its consumer-domain home.
 - **Dependency survey (hand-roll vs adopt).** Node's stdlib *is* the maintained cross-platform OS layer (`readdir(withFileTypes)`, `homedir`, path semantics); surveyed alternatives fail the dependency bar — file-manager packages (`node-file-manager`, `files-and-folders`, Syncfusion's provider) are whole HTTP apps (fit), drive-letter helpers (`drivelist` native addon, `windows-drive-letters` ~7y stale) fail health/proportionality. The browse backend is a thin adapter over stdlib.
 - **Hidden entries: return-and-flag.** The host stamps `hidden` (POSIX dot convention) and returns everything; the client filters. Display policy stays client-side, and the show-hidden toggle shipped as exactly that client-only change: a fixed-label footer toggle whose state lives in the pressed presentation (`aria-pressed` + check glyph), a dot-led path-draft prefix reveals the hidden entries it names, and the current selection is exempt from both the hidden and the prefix filter (it anchors the two-pane view). Windows' `FILE_ATTRIBUTE_HIDDEN` is not exposed by dirents — documented limitation until a native probe pays for itself.
-- **Path-editor cancel scope: the dialog card.** The browse client's path editor cancels on Escape and on focus leaving the card, both observed at a card-scope wrapper rather than the input — after Tab parks focus on a filtered row the input is off the event path, yet Escape must collapse the editor (not the dialog) and a later focus departure must still cancel. Non-cancel exemptions: window/tab focus loss, in-card focus moves, and pointer paths (rows and the toggle suppress focus steal on mousedown while editing). Separators for seeding and draft-tail filtering are read from the host-resolved root crumb (exact for every root form this backend emits: `/`, `C:\`, `\\server\share\`); the wire-field alternative below records the deferred authoritative form. Combobox semantics between the editor and the list it filters (`aria-expanded`/`aria-controls`/active-descendant, result announcements) are likewise deferred — today they read to assistive tech as separate widgets. Focus parking is a card-wide invariant, not an editor-only one: every pick — editing or not, including right-pane advances and create landings whose columns are replaced — re-parks focus on the selection's row after commit, while every other displacing exit (Enter, Escape, a navigation landing whose new level dropped the focused row, a failed pick or create relist, and the nested create dialog closing) falls back to the crumb edit zone whenever focus actually fell to body, and a show-hidden toggle click that finds focus among the rows parks synchronously on the toggle itself. The guarantee is scoped to the dialog's own node replacements — the Modal has no focus trap, so tabbing past the card's edge legitimately leaves, and the owner's adopt window (where `busy` inerts every control and the dialog is closing either way) is likewise outside it.
-- **Navigation lands selection-anchored, progressively.** Away from the display root (the same collapse the crumb header renders, so crumbs and pane shape never disagree), the browse client's navigate commits the target level the moment it arrives — the editor closes and loading ends on that first settlement, so an Enter-submitted navigation is never withdrawn waiting on more — and a parent leg then upgrades the landing in place: the target's actual parent-level entry re-selected (platform case folding on Windows), its children on the right, so a crumb jump reads as stepping back one pane rather than collapsing to a single column. The parent leg runs under the landing's supersession scope and is aborted on the wire by any newer intent; a failed parent leg, or a truncated parent window lacking the target, leaves the committed single-pane landing — the upgrade must never orphan the selection it exists to anchor. Known boundaries of the progressive shape: a pointer press landing exactly inside the one-RTT upgrade window can lose its click when the pressed row node is replaced (keyboard focus is re-parked on the re-selected row; the pointer window is accepted); on slash platforms (macOS) only a final-segment case drift misses the parent-entry match and keeps the single-pane landing, while ancestor-segment drift still matches — parent entry paths inherit the typed prefix — and lands two panes at the cost of the Home collapse; and navigate always relists both legs even when the target is the currently shown level — a crumb tap doubles as the refresh gesture, so freshness wins over reusing possibly-stale in-hand listings at the cost of up to two host scans.
+- **Path-editor cancel scope: the dialog card.** The browse client's path editor cancels on Escape and on focus leaving the card, both observed at a card-scope wrapper rather than the input — after Tab parks focus on a filtered row the input is off the event path, yet Escape must collapse the editor (not the dialog) and a later focus departure must still cancel. Non-cancel exemptions: window/tab focus loss, in-card focus moves, and pointer paths (rows and the toggle suppress focus steal on mousedown while editing). Separators for seeding and draft-tail filtering are inferred from `listing.home`; the wire-field alternative below records the deferred authoritative form. Combobox semantics between the editor and the list it filters (`aria-expanded`/`aria-controls`/active-descendant, result announcements) are likewise deferred — today they read to assistive tech as separate widgets.
+- **Navigation lands selection-anchored, progressively.** Away from the display root (the same collapse the crumb header renders, so crumbs and pane shape never disagree), the browse client's navigate commits the target level the moment it arrives — the editor closes and loading ends on that first settlement, so an Enter-submitted navigation is never withdrawn waiting on more — and a parent leg then upgrades the landing in place: the target's actual parent-level entry re-selected (platform case folding on Windows), its children on the right, so a crumb jump reads as stepping back one pane rather than collapsing to a single column. The parent leg runs under the landing's supersession scope and is aborted on the wire by any newer intent; a failed parent leg, or a truncated parent window lacking the target, leaves the committed single-pane landing — the upgrade must never orphan the selection it exists to anchor.
 - **Symlinks: follow for enterability.** `stat` probes symlinks (broken/cyclic → skipped); crumbs keep the logical path the operator navigated, and `workspace.create` already canonicalizes via realpath at adoption.
-- **One canonical path shape on the wire.** A listing's `path`, `crumbs[].path`, `entries[].path`, and `home` — and `createDirectory`'s returned path, which clients compare verbatim against the child's next `entries[].path` to anchor the create landing — all ship host-resolved: lexical `resolve()`, never realpath (the symlink ruling above keeps ancestries logical), with homedir() output included since the environment may decorate HOME and the backend resolves it before stamping. Clients compare listing paths verbatim on that promise; the only lexical mirror left in the browse client serves the draft side, the one path a user types and hence naturally non-canonical. Normalizing at the source replaces a client-side mirror of resolve() that had to anticipate every decoration (trailing and repeated separators, dot segments, UNC roots, forward slashes), and the promise binds every browse backend.
 - **Listing levels are bounded, and streamed.** One `list` call returns at most `maxEntries` rows (config, default 1000 — GitHub's web-UI directory-listing bound). The level streams via `opendir` into a name-sorted window of `maxEntries + 1` candidates, so memory stays O(maxEntries) and enterability probing touches only windowed candidates; the wire `DirectoryListing` carries a required `truncated` flag so the client states incompleteness instead of silently missing tail entries. A windowed broken symlink is not backfilled from beyond the window — the eviction already marks the level truncated. Window insertion is binary with an O(1) full-window tail rejection (an oversized level must not pay a window scan per dirent), and `list(path, signal)` threads the carrier's request signal so a scan of a stalled network directory cannot outlive a disconnected caller — every await in the scan (open, each read, each symlink probe) races the signal, an aborted exit abandons rather than awaits the close (Node queues close behind in-flight reads), and abandoned settlements are swallowed so cleanup can never surface as an unhandled rejection. An unbounded level is a memory/responsiveness hole for large or adversarial directories.
 - **Whole-filesystem scope, no roots config.** `workspace.create` accepts arbitrary paths and the API serves bash-driving methods, so a browse root would be UX scoping, not a boundary; configurability without a consumer fails the evidence bar. Deferred until a deployment needs it.
 - **The native backend stays.** Plugin-form was the point: multiple providers can serve the seam (an Electron shell would provide the `native` interaction through its own dialog API). Kind naming: `dialog` was the first pick and was dropped — the browse interaction also presents a dialog (the in-app modal), so the word failed to discriminate; `native` names where the chooser runs.

 - **Adopting a file-manager/drive-enumeration dependency.** Rejected per the survey above; recorded here as the dependency policy requires.
 - **A flip-label show-hidden toggle ("Hide hidden files").** Rejected: a flipping action label is ambiguous between state and action and doubles the negative; the fixed label with a pressed presentation states both at once.
 - **Pure relatedTarget blur cancellation (no mousedown suppression).** Rejected: Safari does not focus buttons on pointer down, so a click's focusout carries a null `relatedTarget` and would cancel the editor before the click lands; editing-scoped mousedown suppression plus the card-anchored relatedTarget guard covers pointer and keyboard paths together.
-- **A wire `separator` field on `DirectoryListing` (host stamps `path.sep`).** Deferred, not rejected: it is the authoritative form. The root-crumb read the client uses today is exact for every root shape this backend emits, but it still infers a platform fact from path text and promotes "the chain starts at the root" from backend behavior into a client-relied invariant (the `crumbs` JSDoc does promise it), and it degrades to the old home-text heuristic on an empty chain; a wire field would travel verbatim and survive empty chains and future backends. It touches the seam type and every backend, so the browse client's `separatorOf` carries a TODO pointing at this alternative until a wire change is next scheduled.

 - **不用 `ctx.fs` seam。** `packages/fs/` 是面向模型／会话的存储栈（policy 事件、sandbox 可换后端）。骑上去会把 GUI 浏览耦合进模型的限制后端——为模型换 `fs-sandbox` 绝不能改变 GUI 行为——而 OS 事实（home 锚定、隐藏约定）也不是存储原语。picker seam 保持无展示、无模型；`packages/host/` 是它消费方域的家。
 - **依赖调研（手写 vs 引入）。** Node 标准库本身就是维护中的跨平台 OS 层（`readdir(withFileTypes)`、`homedir`、路径语义）；调研过的替代品都过不了依赖门槛——文件管理器包（`node-file-manager`、`files-and-folders`、Syncfusion 的 provider）是整套 HTTP 应用（契合度不过），盘符工具（原生插件 `drivelist`、约七年未更的 `windows-drive-letters`）健康度／比例失当。browse 后端是标准库上的薄适配。
 - **隐藏条目：返回并打标。** 宿主标注 `hidden`（POSIX 点前缀约定）并返回全部条目；客户端过滤。展示策略留在客户端，"显示隐藏"开关正是作为这一纯客户端改动落地：标签固定的 footer 开关，其状态由按下态呈现承载（`aria-pressed` + 勾选符号）；以点开头的路径草稿前缀会显出它所指名的隐藏条目；当前选中项则不受隐藏与前缀两种过滤影响（它锚定着双栏视图）。Windows 的 `FILE_ATTRIBUTE_HIDDEN` 不被 dirent 暴露——记为限制，直到原生探测值回其成本。
-- **路径编辑器的取消范围：对话框卡片。** browse 客户端的路径编辑器在按 Escape 与焦点离开卡片时取消，两者都在卡片范围的包装层而非输入框上监听——Tab 把焦点停到某个过滤命中的行之后，输入框已不在事件路径上，但 Escape 仍须收起编辑器（而非对话框），其后的焦点离开也仍须取消。不取消的豁免：窗口／标签页失焦、卡片内焦点移动，以及指针路径（编辑期间行与开关在 mousedown 时抑制焦点夺取）。预填与草稿末段过滤所用的分隔符从宿主解析的根 crumb 读取（对该后端发出的每种根形态都精确：`/`、`C:\`、`\\server\share\`）；下文的线上字段替代方案记录了被延期的权威形态。编辑器与其过滤的列表之间的 combobox 语义（`aria-expanded`／`aria-controls`／active-descendant、结果播报）同样被延期——目前二者在辅助技术看来是彼此独立的控件。焦点停靠是卡片全域的不变量，而非编辑器独有：每次选取——无论是否处于编辑态，包括右栏推进与各列被替换的创建落地——提交后都把焦点重新停靠到选中项所在的行上，而其余所有会顶离焦点的退出（Enter、Escape、新层级已不含焦点所在行的导航落地、选取或创建失败后的重新列举，以及嵌套创建对话框的关闭）只要焦点确实落到了 body 上，就回落到 crumb 编辑区，而点击"显示隐藏"开关时若发现焦点落在行间，则把焦点同步停靠到开关自身。该保证的范围仅限对话框自身的节点替换——Modal 没有焦点陷阱，所以 Tab 越过卡片边缘属于正当离开，而 owner 的接纳窗口（其间 `busy` 把每个控件置为惰性，且对话框反正正在关闭）同样在此范围之外。

 - **列举层级有上限，且流式处理。** 单次 `list` 至多返回 `maxEntries` 行（配置项，默认 1000——GitHub 网页端目录列举的同一上限）。层级经 `opendir` 流入一个按名排序、容量 `maxEntries + 1` 的候选窗口，内存保持 O(maxEntries)，可进入性探测只触及窗口内候选；线上 `DirectoryListing` 携带必填的 `truncated` 标志，让客户端明示不完整而不是静默缺尾。窗口内的断链符号链接不从窗口外回填——发生过驱逐本身已把层级标记为截断。窗口插入为二分查找、满窗尾部单次比较即拒绝（超大层级不能为每个 dirent 付出一次全窗扫描），且 `list(path, signal)` 透传载体的请求信号，滞塞网络目录的扫描不会在调用方断连后继续存活——扫描中的每个 await（打开、每次读取、每次符号链接探测）都与信号赛跑，中止路径放弃而非等待 close（Node 会把 close 排在在飞读取之后），被放弃的 settlement 全部吞掉，清理不会以未处理拒绝的形式冒出。无上限的层级对超大或恶意构造的目录就是内存／响应性漏洞。

 ## Known Limitations and Deferred Work
 
 - **Windows hidden attribute is not read** — Node dirents do not expose `FILE_ATTRIBUTE_HIDDEN`, so `hidden` means dot-prefixed on every platform until a native probe is worth its cost.
-- **Name-normalizing volumes void the create-path equality** — `createDirectory` promises its return verbatim-equal to the child's next `entries[].path`; Node's namespaced Win32 paths store even trailing-dot/space segments literally, but a volume that rewrites names on storage (NFD normalization on HFS+-style volumes) breaks the match, and the create landing degrades to a two-pane view whose left pane lacks the aria-current row while focus falls back to the crumb edit zone.
 - **No drive-root enumeration** — on Windows the ancestry stops at the drive root; crossing drives waits for the browser UI's path-entry affordance rather than an enumeration primitive here.
 - **Whole-filesystem scope** — no per-deployment browse-root restriction; `workspace.create` accepts arbitrary paths today, so a root here would be UX scoping, not a boundary — deferred until a deployment needs it.

 ## 已知限制与延期工作
 
 - **不读取 Windows 隐藏属性**——Node 的 dirent 不暴露 `FILE_ATTRIBUTE_HIDDEN`，因此在所有平台上 `hidden` 都意味着点前缀，直到原生探测值回其成本为止。
-- **名称规范化的卷会使创建路径等式失效**——`createDirectory` 承诺其返回值与该子项下一次的 `entries[].path` 逐字相等；Node 带命名空间的 Win32 路径连末尾点／空格段都按字面存储，但在存储时改写名称的卷（HFS+ 风格卷上的 NFD 规范化）会破坏这一匹配，创建落地随之退化为左栏缺少 aria-current 行的双栏视图，同时焦点回落至 crumb 编辑区。
 - **不枚举盘符根**——Windows 上祖先链止于盘符根；跨盘依赖浏览器 UI 的路径输入入口，而不是这里的枚举原语。
 - **全盘可浏览**——没有按部署限定的浏览根；`workspace.create` 今天就接受任意路径，这里的根只会是 UX 范围而非边界——等到有部署需要时再做。

 The **workspace-directory picking seam** for the web-GUI host: an abstract `DirectoryPicker` service (`ctx.directoryPicker`) whose single contract method `capability()` returns a discriminated capability describing how an operator selects a directory. Backends differ in interaction shape, not just mechanism, so the seam models the shapes explicitly instead of one method set: `{ kind: 'native', pick(signal) }` opens one native OS chooser on the host display ([`-native`](../directory-picker-native/README.md)); `{ kind: 'browse', list(path?), createDirectory(path, name) }` serves listing/creation primitives an in-app browser drives, which works for remote clients no OS chooser can reach ([`-browse`](../directory-picker-browse/README.md)). Consumers switch on `capability().kind`; the union derives from the merge-extensible `DirectoryPickerCapabilities` map (a new backend declaration-merges its shape there), and the documented default for an unknown kind is to hide the picking affordance rather than fail. The capability object must be stable for the service lifetime. The client side mirrors the seam without a wire advertisement: each backend package is dual-face, its browser half registering the matching picking interaction into ui-workspace's directory-flow slots — so one composition row swaps both the host capability and the client flow together.
 
-Browse primitives fail with the typed `DirectoryPickerError` (`directory-unreadable` / `directory-exists` / `directory-create-failed`, each carrying the subject `path`), which the consuming gateway maps 1:1 onto wire error codes. `DirectoryEntry` rows carry a host-owned `hidden` flag (POSIX dot convention) so display policy stays client-side; `DirectoryListing.crumbs` is the ancestor chain from the filesystem root, every crumb a jump target. Every path in one listing — and `createDirectory`'s returned path — ships in host-resolved canonical shape (lexical `resolve()`, never realpath): clients compare listing paths verbatim, so every backend must resolve before stamping. Design rationale, the `ctx.fs` separation, and the policy decisions live in [the directory-picker capability seam Agent Note](../../../.agents/notes/implemented/architecture/2026-07-28-directory-picker-capability-seam.md).
+Browse primitives fail with the typed `DirectoryPickerError` (`directory-unreadable` / `directory-exists` / `directory-create-failed`, each carrying the subject `path`), which the consuming gateway maps 1:1 onto wire error codes. `DirectoryEntry` rows carry a host-owned `hidden` flag (POSIX dot convention) so display policy stays client-side; `DirectoryListing.crumbs` is the ancestor chain from the filesystem root, every crumb a jump target. Design rationale, the `ctx.fs` separation, and the policy decisions live in [the directory-picker capability seam Agent Note](../../../.agents/notes/implemented/architecture/2026-07-28-directory-picker-capability-seam.md).

An enforcing guard instead decides on `tools/pre-execute`, where a `deny` becomes the call's error result and the operation never dispatches.

On Windows, `pinsNativeWindowsStdout` additionally compares the complete `stdout.expected.windows.jsonl` after the shared expected output and requires that sidecar exactly when enabled. A scenario whose driven behavior needs POSIX process semantics (e.g. cancelling a live bash call kills a detached process group) declares `posixOnly`, which skips its run test on Windows while the fixture guards keep covering its committed files everywhere.

-## Session store
-
-`resolveSessionsRoot()` resolves the shared session-store root under the Harness home, by the same precedence as `resolveDshHome()`. `SESSIONS_DIR_NAME` owns its directory name: `sessions`. Every surface that persists sessions resolves this one directory, so history is shared across working directories instead of scattered per project; a persistence backend may still partition inside it. Two surfaces resolving different roots would silently split one user's history into disjoint stores, which is why the location is owned here rather than joined per caller.

 This package is intentionally small and harness-dep-free so product packages can share user-data path conventions without depending on one another.

-# code-mode
-
-English | [中文](README.zh.md)
-
-Code Mode over the shipped TUI: the model stops calling one tool per turn and instead writes TypeScript programs for a single `run_code` tool, executed in a worker thread.
-
-This leaf is an **overlay**, not a tree. `dsh --config` includes the shared [`apps/cli/base.cordis.yml`](../../apps/cli/base.cordis.yml), applies the [`tui.cordis.yml`](../../apps/cli/tui.cordis.yml) surface overlay, then applies this file — all as sibling patch lists at one include level.
-
-## Run it
-
-```sh
-# repo root .env (gitignored) or exported env:
-#   DEEPSEEK_API_KEY=sk-…
-#   DEEPSEEK_BASE_URL=https://…   # optional; defaults to the public API
-pnpm run demo:code-mode
-```
-
-`pnpm run demo:code-mode acp` boots the same idea over the ACP transport from [`examples/acp-agent/code-mode.cordis.yml`](../acp-agent/code-mode.cordis.yml).
-
-## What the overlay changes
-
-| Row | Change |
-| --- | --- |
-| `tools` | `mode: code` — the wire registry collapses to `run_code` plus its generated TypeScript SDK prompt section |
-| `system-prompt` | a persona telling the model to batch tool work into one program |
-| `tui` | a Code Mode welcome line |
-| `code-runtime` | inserted: `@deepseek-ai/dsh-code-runtime-worker`, the worker thread `run_code` executes in |
-
-Everything else — the model backend, executors, filesystem tools, persistence, delegation, and the front door — comes from the base and the TUI overlay.
-
-A patch replaces a row's whole `config` rather than merging into it, so each row above restates every key it owns. A patch whose `id` matches no row is skipped with a Loader warning, so renaming a row in the base or the surface overlay requires updating this file.
-
-## Model Experience
-
-The model sees one tool instead of the full native registry. Its request carries the `run_code` schema and a generated TypeScript SDK section describing the callable surface, which costs more prompt tokens up front but replaces many single-call turns with one program — fewer round trips and fewer intermediate tool results in the transcript. Because the tool catalog is part of the cached request prefix, switching modes invalidates the KV cache for the session.

-
-在交付的 TUI 之上启用 Code Mode：模型不再每轮调用一个工具，而是为单一的 `run_code` 工具编写 TypeScript 程序，并在 worker 线程中执行。
-
-本叶节点是一个 **overlay**，而不是配置树。`dsh --config` 会 include 共享的 [`apps/cli/base.cordis.yml`](../../apps/cli/base.cordis.yml)，应用 [`tui.cordis.yml`](../../apps/cli/tui.cordis.yml) surface overlay，再应用本文件——三者都是同一 include 层级上的平级 patch 列表。
-
-## 运行
-
-```sh
-# repo root .env (gitignored) or exported env:
-#   DEEPSEEK_API_KEY=sk-…
-#   DEEPSEEK_BASE_URL=https://…   # optional; defaults to the public API
-pnpm run demo:code-mode
-```
-
-`pnpm run demo:code-mode acp` 通过 ACP 传输启动同样的思路，配置位于 [`examples/acp-agent/code-mode.cordis.yml`](../acp-agent/code-mode.cordis.yml)。
-
-## 该 overlay 改动了什么
-
-| 配置项 | 改动 |
-| --- | --- |
-| `tools` | `mode: code`——线上注册表收敛为 `run_code`，外加其生成的 TypeScript SDK 提示词片段 |
-| `system-prompt` | 指示模型把相关工具调用批量写进一个程序的 persona |
-| `tui` | Code Mode 的欢迎行 |
-| `code-runtime` | 新插入：`@deepseek-ai/dsh-code-runtime-worker`，即 `run_code` 的执行 worker 线程 |
-
-其余部分——模型后端、执行器、文件系统工具、持久化、委派与前端入口——全部来自 base 与 TUI overlay。
-
-配置 patch 会整体替换该配置项的 `config`，而非与其合并，因此上表每一行都必须重述自己拥有的全部键。若某个 patch 的 `id` 不再匹配任何配置项，Loader 只会告警并跳过它，所以在 base 或 surface overlay 中重命名配置项时必须同步更新本文件。
-
-## Model Experience（模型体验）
-
-模型看到的是一个工具，而不是完整的原生注册表。其请求携带 `run_code` 的 schema 以及一段生成的 TypeScript SDK 说明，用于描述可调用面。这会在前置阶段消耗更多提示词 token，但把多个单次调用的轮次压缩为一个程序——往返更少，transcript 中的中间工具结果也更少。由于工具目录属于被缓存的请求前缀，切换模式会使该会话的 KV 缓存失效。

-建议型 guard 的提示以 `additionalContexts` 形式附在 `tools/post-execute` 决策中传递；agent loop 会在该步骤的工具结果之后，将其追加为有日志记录、来源为插件的 `user/message` 事件（参见[工具包](../core/tools)）。因此，此类 guard 告诉模型的所有内容都能从会话日志中重建。强制型 guard 则在 `tools/pre-execute` 上做出决策，其 `deny` 会成为该调用的错误结果，操作绝不会分派执行。

 ## 功能
 
-注册一个工具 `todo_write(todos: [{ content, status }])` 到 `ctx.tools`。模型每次调用都会发送完整列表，不存在部分更新或单项编辑。每次调用都会向调用 agent 的会话日志追加 `todo/write` 事件（完整列表快照），具体调用 `agent.session.append('todo/write', { todos })`；当前列表是最新的该类事件（回放时后写者胜）。
+注册一个工具 `todo_write(todos: [{ content, status }])` 到 `ctx.tools`。模型每次调用都会发送完整列表，不存在部分更新或单项编辑。每次调用都会向调用 agent 的会话日志追加 `todo/write` 事件（完整列表快照），具体调用 `agent.session.append('todo/write', { todos })`；当前列表是最新的该类事件（回放时后写覆盖先写）。
 
 `status` 是 `pending`、`in_progress` 或 `completed` 之一。
 
 ## 单一所有者
 
-该列表属于调用工具的唯一 agent 会话。不存在 subagent／共享／swarm scope：非 agent 调用方（没有 `exec.agent`）无处写入列表，因此会被拒绝。这是有意设置的 scope 限制，详见 Agent Note。

 ## 验证
 
-除 schema 的类型／必填／枚举检查外，`execute` 还会拒绝空或重复的 `content`、同时存在多个 `in_progress` 任务的情况（连贯计划最多只有一个活跃任务），以及 `content`/`status` 之外的任何条目键——扩展条目形状（id、嵌套）会响亮失败而不是被静默压平，保证落日志的快照与模型自认为写入的内容一致。顺序与保持列表最新的纪律由模型根据工具描述负责。

Subject: [PATCH 160/212] Web composer stats detail row and input-zone polish

Stats line moves into the InputBar's new footer slot (sharing the card's
width column) and expands to the design's grouped detail row: turns/steps,
LLM and tool wall time, cache hit, and input/output token split, all
derived client-side from the snapshot. The composer stack owns one 8px
rhythm, the seat fades the transcript through a fixed 36px gradient band,
back-to-bottom follows a live --dsh-composer-height, and goal/todo strips
share one 752px tip-fill column.

+Status: implemented

+
+## Problem
+
+The web composer footer showed a single joined stats string (cache/tokens/turns/steps) in its own stack row, visually detached from the input card and missing the design's duration and token-split details. The input zone itself had accumulated per-entry spacing hacks: dock strips carried their own margins, the sticky seat sat on a solid fill that clipped the transcript hard, the back-to-bottom control cleared the composer by a hardcoded offset that broke as the draft grew, and the goal and todo strips disagreed on surface color and column width.
+
+## Decision
+
+**The stats line renders inside the InputBar's width column through a new `footer` owner prop and expands to the design's grouped detail row; the composer stack owns one 8px rhythm; the seat fades the transcript through a fixed 36px token-bound gradient; the back-to-bottom control follows a live `--dsh-composer-height`; goal and todo share one 752px tip-fill column.**
+
+- `'conversation.composer.dock'` entries reach the page as the `ComposerBarOwnerProps.footer` slot, rendered under the card inside the bar's `.root`, so the stats line and the card share one width constraint. `StatsLine` derives everything client-side from the snapshot: turns/steps, LLM wall time from assistant `timing` (`completedTime - stepStartTime`), tool wall time from tool-result `time - callTime` pairs, prompt/output token split with cache-read folded into input, and cache-hit percentage. Groups render pipe-separated and drop out whole when empty; `formatTokens` (517 / 12.2K / 1.2M) and `formatDuration` (45.2s / 2m42s) are exported for tests. Durations cover only in-window nodes — the README owns that limitation.
+- `.composerStack` carries `gap: 8px` and entries carry no outer margins (QueueDock's margin removed), so a dock entry that renders null costs nothing. GoalBar is the one deliberate exception: `margin: 0 auto -10px` cancels the gap and tucks its square bottom edge 2px under the card.
+- The sticky seat's background is a `linear-gradient` from `color-mix(bg-base 0%, transparent)` at 0px to solid `bg-base` at 36px — pixel stops, not the figma export's percentage, so a growing draft widens only the solid region; `color-mix` keeps both themes fading from their own base.
+- A `useCallback` ref on the seat attaches a ResizeObserver that publishes `--dsh-composer-height` on the scroll body; ChatView's back-to-bottom slot computes `bottom` from it (152px first-paint fallback) instead of the prior hardcoded 168px.
+- The textarea's 52px two-line floor applies to the hero variant only; the docked composer collapses to content height. Goal and todo strips both use the 44px-gutter / 752px-cap column with the todo `tip` fill and l1 border; the todo header is compacted (13/20 type, 8+8 padding) so its collapsed height equals the goal strip's 38px.
+
+## Alternatives considered
+
+**Percentage gradient stops (the figma export's 24%).** Rejected: the stop scales with seat height, so a tall draft stretches the fade band over most of the transcript; the fixed 36px band equals the design's 24% at the resting ~150px composer and stays constant as the composer grows.
+
+**A skeleton-owned dock column with a generic "bottommost entry tucks" contract.** Built and backed out in review: a `.inputDock` wrapper owning width/rhythm plus `--dsh-dock-tuck-*` vars on `:last-child` would retarget the tuck automatically on reorder, but it rewrote every entry and the GoalBar DOM ahead of a pending merge. Per-entry CSS with GoalBar owning its own tuck was chosen; the generic column remains available if dock entries multiply.
+
+**Backend-supplied duration fields for the stats line.** Unnecessary: assistant `timing` and tool call/result pairs already reach the snapshot, so wall times fold client-side with no new session event or host projection.
+
+**Keeping the stats line as a composer-stack sibling.** Rejected: as a stack row it carried its own width constraint that drifted from the card's; as the bar's `footer` both share one column and the stats participate in the seat's sticky/gradient region by construction.
+
+## Consequences
+
+The stats row now reads turns/steps, LLM and tool durations, cache hit, and input/output tokens at a glance, at the cost that durations cover only the loaded event window (README Known Limitation). The one-gap stack rhythm makes dock spacing composition-independent, but GoalBar's tuck is positional: it must stay the bottommost dock entry (`order: 1`) or its negative margin tucks it under the wrong neighbor. The fade band is a constant 36px, so any future design retune is one stop value. `chat-stats-bash-sample.spec.tsx` pins the derivation (timing/tool folds, token split), both formatters, the grouped render, and the zero-renders-during-streaming acceptance.

+## Problem
+
+Web 编辑器页脚原本以独立 stack 行显示一条拼接的统计字符串（cache／tokens／turns／steps），视觉上与输入卡脱节，且缺少设计稿中的耗时与 token 拆分细节。输入区自身也积累了逐条目的间距补丁：dock 条各带自己的 margin，sticky 座位下是硬切消息流的纯色填充，「回到底部」控件用硬编码偏移躲避编辑器、草稿一长高就失效，goal 与 todo 条的底色和列宽也互不一致。
+
+## Decision
+
+**统计行经由新的 `footer` owner prop 渲染进 InputBar 的宽度列内，并扩展为设计稿的分组细节行；composer stack 拥有唯一的 8px 节奏；座位以固定 36px 的 token 绑定渐变淡出消息流；「回到底部」控件跟随实时的 `--dsh-composer-height`；goal 与 todo 共用一条 752px 的 tip 填充列。**
+
+- `'conversation.composer.dock'` 条目以 `ComposerBarOwnerProps.footer` 席位到达页面，渲染在卡片下方、bar 的 `.root` 之内，统计行与卡片因此共享同一宽度约束。`StatsLine` 全部在客户端从快照推导：turns／steps、由 assistant `timing`（`completedTime - stepStartTime`）折算的 LLM 墙钟时间、由 tool-result 的 `time - callTime` 配对折算的工具墙钟时间、把 cache-read 并入输入侧的提示／输出 token 拆分，以及缓存命中率。各组以竖线分隔、无数据时整组消失；`formatTokens`（517 / 12.2K / 1.2M）与 `formatDuration`（45.2s / 2m42s）导出供测试。耗时只覆盖窗口内节点——该限制由 README 记录。
+- `.composerStack` 携带 `gap: 8px`，条目不带外边距（QueueDock 的 margin 已删除），渲染为 null 的 dock 条目零成本。GoalBar 是唯一的刻意例外：`margin: 0 auto -10px` 抵消 gap，把方形下缘塞进卡片下方 2px。
+- sticky 座位的背景是从 0px 处的 `color-mix(bg-base 0%, transparent)` 到 36px 处纯色 `bg-base` 的 `linear-gradient`——像素节点而非 figma 导出的百分比，草稿长高只扩大纯色区域；`color-mix` 让两个主题都从各自的底色淡出。
+- 座位上的 `useCallback` ref 挂 ResizeObserver，把 `--dsh-composer-height` 发布到滚动体上；ChatView 的回到底部席位据此计算 `bottom`（首帧回退 152px），替换先前硬编码的 168px。
+- textarea 的 52px 两行下限只保留在 hero 变体；停靠态编辑器折叠到内容高度。goal 与 todo 条统一使用 44px 边距／752px 上限的列、todo 的 `tip` 填充与 l1 边框；todo 表头紧凑化（13/20 字号、8+8 内边距），折叠高度与 goal 条的 38px 对齐。
+
+## Alternatives considered
+
+**百分比渐变节点（figma 导出的 24%）。** 否决：节点随座位高度缩放，长草稿会把过渡带拉伸到消息流的大半；固定 36px 过渡带等于设计稿在静息 ~150px 编辑器下的 24%，且随编辑器长高保持恒定。

+**骨架拥有的 dock 列加通用「最底条目贴卡」契约。** 实现后在评审中撤回：由 `.inputDock` 包装层拥有宽度／节奏、在 `:last-child` 上发布 `--dsh-dock-tuck-*` 变量，重排时贴卡会自动换人，但它在一次待合并前重写了每个条目和 GoalBar 的 DOM。最终选择逐条目 CSS、GoalBar 自持贴卡；dock 条目增多时通用列方案仍然可用。
+
+**由后端为统计行提供耗时字段。** 不必要：assistant `timing` 与工具 call/result 配对已经到达快照，墙钟时间可在客户端折算，无需新的会话事件或 host 投影。
+
+**统计行保持为 composer stack 的兄弟节点。** 否决：作为 stack 行它携带独立的宽度约束、与卡片漂移；作为 bar 的 `footer`，两者共享一列，统计行也天然落在座位的 sticky／渐变区域内。
+
+## Consequences
+
+统计行现在一眼可读 turns／steps、LLM 与工具耗时、缓存命中和输入／输出 token，代价是耗时只覆盖已加载事件窗口（README 已知限制）。单 gap 的 stack 节奏使 dock 间距与组合无关，但 GoalBar 的贴卡是位置性的：它必须保持为最底的 dock 条目（`order: 1`），否则其负边距会塞到错误的邻居下面。过渡带恒为 36px，未来设计调整只改一个节点值。`chat-stats-bash-sample.spec.tsx` 钉住推导（timing／工具折算、token 拆分）、两个格式化器、分组渲染，以及流式期间零重渲染的验收。

 ## Known Limitations and Deferred Work
 
-- **The stats line has no duration segment** — assistant `usage` carries token accounting only; elapsed-time needs a host data source.
+- **Stats-line durations cover the in-window flow only** — LLM and tool wall times fold the snapshot's assistant `timing` and tool call/result pairs, so nodes outside the loaded event window (older history) are not counted.
 - **Details panel is the minimal form and currently has no entry point** — selected call args/result raw display; the Input/Output/Metadata switch, Prev/Next stepping, and See-in-trajectory deep link are deferred. Tool rows stopped being details-panel click targets and nothing replaced that gesture, so `ChatViewInjected.openDetails` is implemented but uncalled and the panel (including its terminal card) is unreachable in the assembled application; its rendering stays covered by mounting it with a selection directly.
 - **Assistant per-message paging is a reserved slot** — drawn in the design, not implemented. The finalized IconActions row (copy / branch / clock) ships; branch remains a chrome stub.
 - **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.

 ## 已知限制与暂缓事项
 
-- **统计行没有耗时区段**：assistant `usage` 只携带 token 计数；耗时需要主机数据源。
+- **统计行的耗时只覆盖窗口内消息流**：LLM 与工具墙钟时间由快照的 assistant `timing` 与工具 call/result 配对折算，落在已加载事件窗口之外的节点（更早的历史）不计入。
 - **详情面板是最小形态，且当前没有入口**：以原始形式显示已选择调用的参数／结果；Input/Output/Metadata 切换、Prev/Next 步进与 See-in-trajectory 深链接暂缓实现。工具行已不再是详情面板的点击目标，且没有任何手势接替它，因此 `ChatViewInjected.openDetails` 虽已实现却无人调用，该面板（含其终端卡片）在组装后的应用中不可达；其渲染仍由直接以选中态挂载它来覆盖。
 - **assistant 逐消息分页是预留 slot**：设计中已有图稿，尚未实现。已定稿的 IconActions 行（复制／分支／时钟）已落地；分支仍是 chrome stub。
 - **others 工具行的闪光图标是手绘近似版本**：无法在本地导出设计字形的矢量几何；等到存在精确导出后再将其提升到 ui-primitives。

The accepted cost is that inter-tier discipline is upheld by review rather than a machine gate and every new app snapshot must avoid unstable layout or clock output.

-The lane ships gate-exempt inside `pnpm run test:web`, exactly as that config's header records. Adding chromium to CI would reverse the "no browser infrastructure in CI" premise in the [GUI testing note](../process/2026-07-20-gui-testing-system.md) and therefore requires its own Agent Note cross-linked from there, staged as a non-required job first with measured promotion criteria (consecutive green runs, wall time, zero-retry flake budget, runner browser-cache strategy). `TODO(ci-browser)` marks the seam. Scenarios are POSIX-oriented (the lane is not in the Windows matrix).
+The lane is a required compare-only gate for Linux pull requests under the [browser snapshot CI decision](2026-07-30-web-browser-snapshot-ci-gate.md). The static job publishes `apps/web/dist` with the package build artifacts; the consumer job installs the lockfile-selected Chromium, restores its OS-and-lockfile-keyed cache, and runs the lane with `DSH_SNAPSHOT=replay`. CI never records or refreshes goldens. The default-branch Linux serial jobs run the same comparison and seed the hosted browser cache. Scenarios remain POSIX-oriented and stay outside the Windows and macOS matrices.

+# Agent Note: Required CI gate for web browser expected outputs
+
+Status: implemented
+
+English | [中文](2026-07-30-web-browser-snapshot-ci-gate.zh.md)
+
+## Problem
+
+The [keyless web browser e2e lane](2026-07-24-web-gui-browser-e2e-lane.md) runs only under the local `pnpm run test:web` command, and PR CI does not compare `apps/web/tests/snapshots/**/*.expected.md`. A PR that changes user-visible web output can therefore remain green when its expected outputs are not refreshed; when any later branch explicitly runs `DSH_SNAPSHOT=refresh`, it backfills the earlier change and produces a diff unrelated to that branch. Ordinary local runs already default to read-only replay, so the gap is mandatory enforcement at the PR level, not a ban on writes in refresh mode.
+
+## Decision
+
+For Linux PRs, the `node 24 / snapshots and artifacts` job must run the full web browser replay/compare suite. `scripts/run-gates.ts` registers `test:web:built` as a `ci-consumers` gate and explicitly injects `DSH_SNAPSHOT=replay`; CI never runs in `record` or `refresh` mode, so when the committed goldens disagree with the currently assembled application, the tests fail directly instead of silently rewriting them on the runner and then passing.
+
+The static CI job already builds all publishable artifacts; it puts `apps/web/dist` and the package `lib/` directories in the built-tree artifact, which the consumer job reuses without rebuilding the entire repository. The consumer job installs Chromium and its system dependencies at the Playwright version in the lockfile, and caches the browser by operating system and the `pnpm-lock.yaml` hash. The default branch's serial Linux job runs the same compare command and populates the default-branch cache, which subsequent PRs can restore directly.
+
+Local `pnpm run test:web` continues to build first and then run the full browser suite; `test:web:built` is the entry point for existing build artifacts. Developers explicitly run `DSH_SNAPSHOT=refresh pnpm run test:web` only after confirming that user-visible output changed intentionally, review every expected-output diff, and then verify again in replay mode that no files are written.
+
+The gate remains Linux-only: these scenarios target POSIX, and the Windows and macOS serial reference jobs do not run them again. A PR's `all checks passed` verdict already depends on the consumer job, so a browser compare failure blocks the merge without requiring a new branch-protection check name.
+
+## Alternatives considered
+
+**Continue requiring only local runs.** Rejected: execution depends on developer memory, which is precisely why stale goldens drift across PRs, and cannot guarantee that the PR introducing a behavior change carries its own expected-output diff.
+
+**Run CI in `refresh` mode and then check the working tree.** Rejected: checking after writing turns the assertion mechanism into a generator; if the working-tree check is wired incorrectly, it can turn a regression into a passing expected-output update. Replay compares the existing goldens directly and has a smaller failure surface.
+
+**Create a standalone browser job and rebuild the entire repository.** Rejected: it would duplicate dependency installation and the publishable build. The existing Linux consumer job already consumes the same built-tree artifact and is part of the unified required verdict.
+
+**Replace real Chromium with jsdom snapshots.** Rejected: jsdom does not cover the browser, HTTP/SSE carriage, or the composition of real client plugin bundles. It remains useful for fast lower-layer feedback, but cannot replace the assembled browser chain.
+
+## Consequences
+
+Before merge, every PR proves that the current web assembly matches all committed browser expected outputs, turning a missed refresh from an “unrelated change in a later PR” into a failure in the PR that introduced it. The cost is Chromium provisioning and one serial pass through the browser scenarios in Linux CI; built-artifact reuse and the default-branch browser cache avoid duplicate builds and routine downloads. The gate still makes no claim of cross-platform browser consistency, and if a Playwright/Chromium upgrade changes the ARIA format, the upgrade PR must explicitly refresh the expected outputs and review the churn.

+# Agent Note: Web 浏览器预期输出的必需 CI 门禁
+
+Status: implemented
+
+[English](2026-07-30-web-browser-snapshot-ci-gate.md) | 中文
+
+## 问题
+
+[无密钥 Web 浏览器 e2e 车道](2026-07-24-web-gui-browser-e2e-lane.md)只由本地 `pnpm run test:web` 运行，PR CI 不比较 `apps/web/tests/snapshots/**/*.expected.md`。因此，改变用户可见 Web 输出的 PR 可以在漏刷预期输出时保持绿色；后来任意分支显式运行 `DSH_SNAPSHOT=refresh`，都会替前序变更补账并产生与本分支无关的 diff。普通本地运行已经默认使用只读 replay，缺口是 PR 级的强制执行，而不是禁止 refresh 写入。
+
+## 决策
+
+Linux PR 的 `node 24 / snapshots and artifacts` 必须运行完整 Web 浏览器 replay/compare。`scripts/run-gates.ts` 把 `test:web:built` 作为 `ci-consumers` 的一个 gate，并显式注入 `DSH_SNAPSHOT=replay`；CI 永不以 `record` 或 `refresh` 模式运行，因此提交的 golden 与当前组装应用不一致时测试直接失败，不会在 runner 内静默改写后通过。
+
+静态 CI job 已经构建全部发布产物；它把 `apps/web/dist` 连同 package `lib/` 放进 built-tree artifact，consumer job 复用该 artifact 而不重复全仓构建。consumer job 按 lockfile 中的 Playwright 版本安装 Chromium 及系统依赖，并以操作系统和 `pnpm-lock.yaml` 哈希缓存浏览器。默认分支的 Linux 串行 job 运行同一 compare 命令并产出默认分支缓存，后续 PR 可直接恢复。
+
+本地 `pnpm run test:web` 仍先构建再运行浏览器全集；`test:web:built` 是已有构建产物的执行入口。开发者只在确认用户可见输出有意变化后显式运行 `DSH_SNAPSHOT=refresh pnpm run test:web`，评审每一处 expected diff，再以 replay 模式复验不再写文件。
+
+门禁保持 Linux-only：这些场景面向 POSIX，Windows 与 macOS 的串行参考 job 不重复运行。PR 的 `all checks passed` 已依赖 consumer job，因此浏览器 compare 失败会阻止合并，无需新增 branch-protection check 名称。
+
+## 曾考虑的替代方案
+
+**继续只要求本地运行。** 已否决：执行依赖开发者记忆，正是旧 golden 跨 PR 漂移的原因，不能保证产生行为变化的 PR 自己携带 expected diff。
+
+**让 CI 以 `refresh` 模式运行后检查工作树。** 已否决：写后比较把断言机制变成生成器，若工作树检查接线失效就会把回归更新成绿色；replay 直接比较已有 golden，失败面更小。
+
+**新建独立 browser job 并重新构建全仓。** 已否决：它会重复依赖安装和发布构建。现有 Linux consumer job 已消费同一 built-tree artifact，并已被统一的 required verdict 聚合。
+
+**用 jsdom 快照代替真实 Chromium。** 已否决：jsdom 不覆盖浏览器、HTTP/SSE 承载及真实 client plugin bundle 组合；它保留为快速的下层反馈，不能替代 assembled browser chain。
+
+## 后果
+
+每个 PR 都在合并前证明当前 Web 组装与所有已提交的浏览器 expected 一致，漏刷从“后续 PR 的无关变化”变成引入 PR 自己的失败。成本是 Linux CI 增加 Chromium 供给和一轮串行浏览器场景；built artifact 复用与默认分支浏览器缓存避免重复构建和常态下载。门禁仍不声称跨平台浏览器一致性，Playwright/Chromium 升级若改变 aria 格式，升级 PR 必须显式 refresh 并评审 churn。

@@ -10,7 +10,7 @@ How this repo tests, tier by tier, and the rules that keep a green suite meaning
 - **Coverage gate** (`pnpm run test:coverage`): the gating run, per-file 100% on `packages/*/*/src`. An uncovered line is often dead code the gate is correctly flagging for deletion, not a missing test to bolt on. Line coverage is necessary, never sufficient — it proves lines ran, not that the feature works as shipped.
 - **Real-API e2e** (`pnpm run test:e2e`): with-key tests against live provider APIs — the DeepSeek model plus provider-specific smokes that gate on their own keys (`EXA_API_KEY`, `PERPLEXITY_API_KEY`, …); each suite self-skips without its key so keyless CI stays green ([real-API e2e Agent Note](../.agents/notes/implemented/testing/2026-06-19-real-api-e2e-ci.md)).
 - **Snapshot** (`pnpm run test:snapshot`): keyless expected outputs cover external behavior — transport contracts and presentation, while persisted logs pin assembled backend behavior. ACP boots the real automation-server example, replays a recorded session, and diffs normalized JSON-RPC plus the re-persisted log ([ACP snapshot Agent Note](../.agents/notes/implemented/testing/2026-06-19-acp-snapshot-tests.md)); headless pins `stream-json` through its real one-shot process. TUI journeys replay primary/child JSONL through the real loop and tools, then project ANSI into semantic terminal-state outputs; package snapshots retain transient states and a real PTY covers the process boundary ([TUI snapshot Agent Note](../.agents/notes/implemented/testing/2026-07-18-tui-terminal-state-snapshots.md)). Use `pnpm run test:snapshot:record` when a model transcript changes and `pnpm run test:snapshot:refresh` when replay input remains valid; review every JSONL and expected-output diff. One ACP scenario (`text-turn`) pins full system-prompt/tool-schema content; other fixtures tokenize it so an edit churns one line ([pinned-header Agent Note](../.agents/notes/archived/testing/2026-07-06-pin-request-header-content-in-one-scenario.md)).
-- **Web browser snapshot** (gate-exempt `pnpm run test:web`): real chromium over the in-process web composition replays recorded fixtures against conversation aria goldens (`apps/web/tests/snapshots/`); record/refresh semantics and the deferred CI browser decision: [web e2e lane Agent Note](../.agents/notes/implemented/testing/2026-07-24-web-gui-browser-e2e-lane.md). [Runs `build` first](../.agents/notes/implemented/bug-fix/2026-07-28-themed-scrollbars-and-reserved-gutter.md): plugin CSS ships per plugin.
+- **Web browser snapshot** (`pnpm run test:web`; required Linux PR gate): Chromium compares replayed browser output with `apps/web/tests/snapshots/`. CI forces read-only `DSH_SNAPSHOT=replay`, never writing expected outputs; record/refresh stay local and every diff is reviewed ([web e2e lane](../.agents/notes/implemented/testing/2026-07-24-web-gui-browser-e2e-lane.md), [CI gate decision](../.agents/notes/implemented/testing/2026-07-30-web-browser-snapshot-ci-gate.md)). `test:web` [builds first](../.agents/notes/implemented/bug-fix/2026-07-28-themed-scrollbars-and-reserved-gutter.md) for plugin CSS.
 
 Committed session-format JSONL uses the canonical packed-row layout, and the keyless snapshot gate discovers every such fixture by its `session` header. In-flight branches carrying older fixture edits merge current `master` and run the [temporary migrator](../scripts/migrate-packed-session-fixtures.ts) through `pnpm run migrate:packed-session-fixtures`; the [removal proposal](../.agents/notes/proposed/process/2026-07-26-remove-packed-session-fixture-migrator.md) retires that command and these links after all affected branches converge.

 - **覆盖率门禁**（`pnpm run test:coverage`）：门禁级运行，对 `packages/*/*/src` 按文件 100% 覆盖。未覆盖的行往往是门禁正确标记出的死代码（应删除），而非需要补写的测试。行覆盖率是必要条件，但永远不是充分条件：它证明行被执行过，不证明功能按交付预期工作。
 - **真实 API e2e**（`pnpm run test:e2e`）：带密钥测试调用真实提供方 API，包括 DeepSeek 模型以及各提供方特有的冒烟测试；这些测试各自由自己的密钥控制（`EXA_API_KEY`、`PERPLEXITY_API_KEY` 等），缺少密钥时套件会自动跳过，使 keyless CI 保持绿色（[真实 API e2e Agent Note](../.agents/notes/implemented/testing/2026-06-19-real-api-e2e-ci.md)）。
 - **快照**（`pnpm run test:snapshot`）：无密钥预期输出覆盖对外行为（传输契约与呈现），持久化日志则固定组装后的后端行为。ACP 启动真实的自动化服务器示例、回放录制会话，并对归一化 JSON-RPC 与重新持久化的日志执行 diff（[ACP 快照 Agent Note](../.agents/notes/implemented/testing/2026-06-19-acp-snapshot-tests.md)）；headless 通过真实单次运行进程固定 `stream-json`。TUI 旅程通过真实循环与工具回放主会话与子会话 JSONL，再将 ANSI 投影为语义化终端状态输出；包级快照保留瞬态状态，真实 PTY 覆盖进程边界（[TUI 快照 Agent Note](../.agents/notes/implemented/testing/2026-07-18-tui-terminal-state-snapshots.md)）。当模型 transcript（文本记录）发生变化时使用 `pnpm run test:snapshot:record`，回放输入仍然有效时使用 `pnpm run test:snapshot:refresh`；请审查每一处 JSONL 与预期输出差异。一个 ACP 场景（`text-turn`）固定完整的系统提示词与工具 schema 内容；其他 fixture（测试前置数据）将其 token 化，因此修改只会扰动一行（[pinned-header Agent Note](../.agents/notes/archived/testing/2026-07-06-pin-request-header-content-in-one-scenario.md)）。
-- **Web 浏览器快照**（豁免门禁的 `pnpm run test:web`）：真实 chromium 在进程内 web 组装之上回放已录制 fixture，与会话区 aria 预期输出比对（`apps/web/tests/snapshots/`）；`DSH_SNAPSHOT=record`/`refresh` 的语义与暂缓的 CI 浏览器决策见 [web e2e 车道 Agent Note](../.agents/notes/implemented/testing/2026-07-24-web-gui-browser-e2e-lane.md)。[先跑 `build`](../.agents/notes/implemented/bug-fix/2026-07-28-themed-scrollbars-and-reserved-gutter.md)：插件 CSS 按插件分别发布。
+- **Web 浏览器快照**（`pnpm run test:web`；必需的 Linux PR（Pull Request）门禁）：Chromium 将回放后的浏览器输出与 `apps/web/tests/snapshots/` 比较。CI 强制只读的 `DSH_SNAPSHOT=replay`，绝不写入预期输出；record/refresh 留在本地，每处 diff 都须评审（[web e2e 车道](../.agents/notes/implemented/testing/2026-07-24-web-gui-browser-e2e-lane.md)、[CI 门禁决策](../.agents/notes/implemented/testing/2026-07-30-web-browser-snapshot-ci-gate.md)）。`test:web` 会[先构建](../.agents/notes/implemented/bug-fix/2026-07-28-themed-scrollbars-and-reserved-gutter.md)以交付插件 CSS。
 
 签入仓库的会话格式 JSONL 使用规范打包行布局，无密钥快照门禁会通过 `session` header 发现每一份此类 fixture。仍携带旧版 fixture 改动的在途分支应合并当前 `master`，并通过 `pnpm run migrate:packed-session-fixtures` 运行[临时迁移器](../scripts/migrate-packed-session-fixtures.ts)；待所有受影响分支收敛后，[移除提案](../.agents/notes/proposed/process/2026-07-26-remove-packed-session-fixture-migrator.md)会移除该命令及这些链接。

The static job publishes `apps/web/dist` with the package build artifacts; the consumer job installs the lockfile-selected Chromium, restores its OS-and-lockfile-keyed cache, and runs the lane with `DSH_SNAPSHOT=replay`. CI never records or refreshes goldens. The default-branch Linux serial jobs run the same comparison and seed the hosted browser cache. Scenarios remain POSIX-oriented and stay outside the Windows and macOS matrices.

 For Linux PRs, the `node 24 / snapshots and artifacts` job must run the full web browser replay/compare suite. `scripts/run-gates.ts` registers `test:web:built` as a `ci-consumers` gate and explicitly injects `DSH_SNAPSHOT=replay`; CI never runs in `record` or `refresh` mode, so when the committed goldens disagree with the currently assembled application, the tests fail directly instead of silently rewriting them on the runner and then passing.
 
-The static CI job already builds all publishable artifacts; it puts `apps/web/dist` and the package `lib/` directories in the built-tree artifact, which the consumer job reuses without rebuilding the entire repository. The consumer job installs Chromium and its system dependencies at the Playwright version in the lockfile, and caches the browser by operating system and the `pnpm-lock.yaml` hash. The default branch's serial Linux job runs the same compare command and populates the default-branch cache, which subsequent PRs can restore directly.

-The lane is a required compare-only gate for Linux pull requests under the [browser snapshot CI decision](2026-07-30-web-browser-snapshot-ci-gate.md). The static job publishes `apps/web/dist` with the package build artifacts; the `node 24 / snapshots and artifacts` consumer job installs the lockfile-selected Chromium, restores its OS-and-lockfile-keyed cache, and runs the lane with `DSH_SNAPSHOT=replay`. CI never records or refreshes goldens. Default-branch serial jobs do not provision Chromium or run the lane. Scenarios remain POSIX-oriented and stay outside the Windows and macOS matrices.

This is an intentional plane split: the host and specs use the [tsx source-launch contract](../architecture/2026-07-29-dsh-source-launch-tsx-esm.md), while the browser consumes `apps/web/dist` and package `lib/client.js` artifacts, so the gate depends on `built-package-invariants` for those client artifacts. The hosted and self-hosted default-branch Linux serial jobs run the same gate; the hosted job produces the browser cache consumed by pull requests, while the persistent self-hosted pool needs no hosted cache. CI never records or refreshes goldens. Scenarios remain POSIX-oriented and stay outside the Windows and macOS matrices.

 For Linux PRs, the `node 24 / snapshots and artifacts` job must run the full web browser replay/compare suite. `scripts/run-gates.ts` registers `test:web:built` as a `ci-consumers` gate and explicitly injects `DSH_SNAPSHOT=replay`; CI never runs in `record` or `refresh` mode, so when the committed goldens disagree with the currently assembled application, the tests fail directly instead of silently rewriting them on the runner and then passing.
 
-The static CI job already builds all publishable artifacts; it puts `apps/web/dist` and the package `lib/` directories in the built-tree artifact, which the consumer job reuses without rebuilding the entire repository. The `node 24 / snapshots and artifacts` consumer job installs Chromium and its system dependencies at the Playwright version in the lockfile, and caches the browser by operating system and the `pnpm-lock.yaml` hash. Default-branch serial jobs do not provision Chromium or run the suite.
+The static CI job already builds all publishable artifacts; it puts `apps/web/dist` and the package `lib/` directories in the built-tree artifact, which the consumer job reuses without rebuilding the entire repository. On hosted runners, CI installs Chromium and its system dependencies at the Playwright version in the lockfile. On the persistent failover VM, the image owns the Linux system packages and CI installs only Chromium, avoiding per-run `apt` mutation. The hosted default-branch Linux serial job runs the suite and produces the operating-system-and-lockfile-keyed browser cache; pull requests restore it without paying compression and upload on the required path, with an operating-system prefix fallback across lockfile changes. The self-hosted standby runs the same comparison without hosted cache actions.
 
 Local `pnpm run test:web` continues to build first and then run the full browser suite; `test:web:built` is the entry point for existing build artifacts. Developers explicitly run `DSH_SNAPSHOT=refresh pnpm run test:web` only after confirming that user-visible output changed intentionally, review every expected-output diff, and then verify again in replay mode that no files are written.
 
-The gate runs only in the Linux PR consumer job: these scenarios target POSIX, and serial reference jobs do not provision Chromium or run the suite. A PR's `all checks passed` verdict already depends on the consumer job, so a browser compare failure blocks the merge without requiring a new branch-protection check name.
+For pull requests, the gate runs only in the Linux consumer job: these scenarios target POSIX, and the other PR jobs do not provision Chromium.

-        "content": "# Development guide\n\nEnglish | [中文](development.zh.md)\n\nThis onboarding guide helps project contributors get started with the local environment, daily workflow, and CI flow; see the Agent Notes for design rationale and technical trade-offs.\n\n## Prerequisites\n\n- Node.js supports 22.19+ and 24+. CI covers 22.19, 24, and 26; see the [Node engine floor Agent Note](../.agents/notes/implemented/process/2026-07-06-node-engine-floor.md).\n- Corepack-enabled pnpm. The repo pins `pnpm@11.7.0` in `package.json`; run `corepack enable` if `pnpm --version` does not resolve through Corepack.\n- Git 2.26 or newer; hook setup enables Git's worktree-specific configuration extension.\n- Optional: a DeepSeek API key for the TUI, headless, and ACP automation demos and real-API e2e tests.\n\n## First-time setup\n\nInstall dependencies from the repo root:\n\n```sh\npnpm install\n```\n\nThe install also runs the root `postinstall` script, which installs lefthook from the repo dev dependency through `scripts/install-lefthook.mjs`. With `CI=true` or `GITHUB_ACTIONS=true`, the wrapper returns before Git discovery because automated jobs do not consume contributor hooks. Otherwise, it requires Git 2.26 or newer and gives the current worktree an explicit hook directory under its own Git directory; linked worktrees therefore use their own lefthook binary and configuration instead of rewriting common hooks. The first install enables Git's worktree-specific configuration extension and repository format 1; see the [worktree-local hooks Agent Note](../.agents/notes/implemented/process/2026-07-27-worktree-local-lefthook.md).\n\nIf hooks are missing because dependencies were restored from cache or `postinstall` was skipped, install them manually:\n\n```sh\nnode scripts/install-lefthook.mjs\n```\n\nThe wrapper refuses user-owned `core.hooksPath` values. An inherited system, global, or common-repository path requires `DSH_LEFTHOOK_ALLOW_HOOKS_PATH_OVERRIDE=1`. When Git seeds a new worktree with another registered worktree's marker-backed hook path, the wrapper replaces that copied value with the new worktree's own path; command-scoped and other worktree-scoped paths must be integrated or removed explicitly.\n\nBefore enabling worktree config, migrate direct `extensions.*` in a format-0 common config, direct `core.worktree` or `core.bare=true`, and any non-empty dormant `config.worktree`. The common config and every worktree config must be regular files, while the owned hook directory may contain only unaliased regular files.\n\nAfter moving a checkout, rerun the wrapper to relocate its owned path and regenerate hooks. For a stale or invalid installer lock, first confirm no installer is running, then remove the reported lock and retry. If installation and hook-path rollback both fail, inspect the reported worktree config before retrying. The [worktree-local hooks Agent Note](../.agents/notes/implemented/process/2026-07-27-worktree-local-lefthook.md) owns the full safety contract.\n\nRun typecheck once after a fresh clone:\n\n```sh\npnpm run typecheck\n```\n\nThat first typecheck runs the whole-repo `tsc -b` graph: it emits every package/vendor `lib/types` and checks examples, tests, and scripts through the two no-emit aggregates described below.\n\n## TypeScript project layout\n\nThe repository's TypeScript configuration has exactly three roles; every tsconfig file plays one of them.\n\n| File | Role | Forms a program? |\n|---|---|---|\n| `tsconfig.json` | Solution root: `extends` base, `files: []`, references to the two aggregates. The whole-repo `tsc -b tsconfig.json` graph, the tsserver discovery entry, and — through the inherited `paths` — the resolution config for tsx running `examples/` and `scripts/` (their nearest tsconfig is this file). | No |\n| `tsconfig.host.json` | Host aggregate: host-side packages (via references), examples, tests, scripts, website. Excludes `packages/client`. | Yes |\n| `tsconfig.client.json` | Client aggregate: `packages/client/*` packages and their tests, `apps/web`. | Yes |\n| `tsconfig.base.json` | Shared compilerOptions and the source `paths` map. Also the resolution facade the vitest configs point vite-tsconfig-paths at: it has no `include`, so its `paths` apply to every importer. | No |\n| `tsconfig.base.client.json` | Browser compiler shape (`jsx`, DOM libs, `types: []`) extended by the client aggregate and every `packages/client/*` package. | No |\n\nHost and client stay two aggregate programs because both sides declaration-merge the cordis `Context` interface under the same keys with different services; one program seeing both merges reports a collision. The collision exists only inside a `ts.Program` — module resolution never triggers it — which is why the solution may reference both aggregates and one paths facade may span both sides. Two disciplines follow:\n\n- `tsconfig.base.json` never gains `include` or `files`: they would leak into every extending package project and narrow the facade's match-all scope.\n- A script that builds a repo-wide `ts.Program` seeds `tsconfig.host.json` or `tsconfig.client.json` explicitly — never the root solution, because flattening both aggregates into one program collides the `Context` merges. Program-backed generators and gates (`scripts/ts-project.ts` consumers, doc-typecheck standalone mode) are host-only by decision; the client side gains program-backed tooling only with a concrete need.\n\nStatic analysis and tests resolve workspace imports through the base `paths` map to `src` and must pass on a clean tree; gates that consume built `lib/` output declare that dependency explicitly. Decision record: [solution-root note](../.agents/notes/implemented/process/2026-07-22-tsconfig-solution-root-two-aggregates.md); the tsc-first emit pipeline is the [ts-build-config note](../.agents/notes/implemented/process/2026-06-17-ts-build-config.md).\n\nIf a relevant local check consumes built package output, build once first:\n\n```sh\npnpm run build\n```\n\n`pnpm run hygiene` includes `publint`, which validates package entrypoints against the built `lib/*.js` files, and `verify-node-next-types`, which validates built declarations against a temporary NodeNext consumer. A fresh worktree has no bundled JS or declarations until `pnpm run build` runs; ordinary commits and pushes do not require that build unless their selected checks consume it.\n\n## Environment variables\n\nThe real DeepSeek adapter and key-backed agent demos read credentials from the environment or from a gitignored `.env` at the repo root:\n\n```sh\nDEEPSEEK_API_KEY=sk-...\nDEEPSEEK_BASE_URL=https://... # optional\n```\n\n`DEEPSEEK_BASE_URL` is optional and defaults to the public API. Never commit real credentials. The real-API e2e suites self-skip when `DEEPSEEK_API_KEY` is not set.\n\n## Git hooks\n\nlefthook is configured in `lefthook.yml` as a fast local checkpoint:\n\n- `pre-commit` applies formatting-only ESLint fixes, validates the staged files with Oxlint and applies its native fixes, checks the staged diff for whitespace errors, and runs the vendor manifest guard.\n- `pre-push` runs only the incremental repository typecheck (`tsc -b` over the root solution, covering both the host and client aggregates).\n\nThe vendor manifest guard checks that changes under `vendor/*/src` are staged with the matching `vendor/README.md` manifest update. See `vendor/README.md` before editing vendored code.\n\nThe hooks intentionally do not run tests, snapshots, documentation checks, builds, or hygiene. Contributors run the [checks relevant to the changed behavior](../AGENTS.md#run-relevant-checks-locally) once; CI owns exhaustive coverage, built-artifact smokes, and the Node 22.19, 24, and 26 compatibility matrix.\n\nContributors can opt into the comprehensive local gate set with `pnpm run check:all`. The command is independent of both Git hooks and is not an agent instruction.\n\n## CI gates\n\nThe keyless [CI workflow](../.github/workflows/ci.yml) groups independent gates into broad lanes and runs a smaller compatibility signal across supported Node versions. Artifact consumers wait for one build within their lane. The separate real-API workflow runs `pnpm run test:e2e` with its configured worker bound. See [scripts/run-gates.ts](../scripts/run-gates.ts) and the workflow files for the current gate and job inventory.\n\n## Daily commands\n\nUse these from the repo root:\n\n```sh\npnpm run test           # unit tests\npnpm run test:coverage  # unit tests with per-file coverage gates\npnpm run test:e2e       # real-API tests; self-skips without DEEPSEEK_API_KEY\npnpm run check:all      # comprehensive opt-in gate set; not wired to Git hooks\npnpm run typecheck      # tsc -b over the root solution: emits package/vendor lib/types, checks both aggregates\npnpm run lint           # oxlint .\npnpm run lint:fix       # formatting-only ESLint, then oxlint . --fix\npnpm run doc-typecheck  # compile checked TypeScript snippets in Markdown docs\npnpm run gen-cordis-catalog     # regenerate docs/cordis-catalog/events.md + services.md from source\npnpm run verify-cordis-catalog  # fail if either cordis catalog is stale\npnpm run verify-export-jsdoc    # fail if a module-level package export lacks complete JSDoc\npnpm run gen-doc-graphs     # regenerate generated relationship docs from source and curated graph definitions\npnpm run verify-doc-graphs  # fail if generated relationship docs are stale\npnpm run verify-md-wrap  # fail on hard-wrapped prose paragraphs in docs/README markdown\npnpm run verify-mermaid  # fail if a ```mermaid diagram has invalid Mermaid syntax\npnpm run verify-type-equiv  # fail if a ```ts type-equiv doc block drifts from its source type\npnpm run verify-doc-budgets  # fail if a budgeted standing doc exceeds its word ceiling\npnpm run gen-translation-brief   # print the minimal-update briefing for out-of-sync translation pairs (--apply splices code-only edits)\npnpm run doc-sync       # all Markdown/doc gates, scheduled concurrently; the doc-sync leaf list in scripts/run-gates.ts is the full list\npnpm run gen-module-graph     # regenerate docs/module-graph.md from package peerDeps\npnpm run verify-module-graph  # fail if docs/module-graph.md is stale\npnpm run build          # emit lib/types intermediates, then bundle lib/index.* runtime files\npnpm run verify-node-next-types  # fail if built declarations are not NodeNext-consumable\npnpm run hygiene        # knip, publint, workspace constraints, and NodeNext declaration check\n```\n\nWhen changing package public behavior, update the relevant README or JSDoc in the same change. `pnpm run doc-sync` catches checked TypeScript snippets, generated doc freshness, markdown wrap/link drift, type equivalence, translation pairing, Mermaid syntax, and doc budgets, but broader prose/API sync still needs review.\n\n## Demos\n\nThe one-shot Headless coding agent needs `DEEPSEEK_API_KEY` in the environment or repo-root `.env`:\n\n```sh\npnpm run demo:headless \"summarize this workspace\"\n```\n\nThe full-screen interactive coding agent needs `DEEPSEEK_API_KEY` in the environment or repo-root `.env`:\n\n```sh\npnpm run demo:tui\n```\n\nThe self-referential cordis-agent demo can inspect and modify its live plugin runtime and needs the same credentials:\n\n```sh\npnpm run demo:cordis\n```\n\nThe ACP automation server exposes fresh agent sessions over JSON-RPC stdio and also needs `DEEPSEEK_API_KEY`:\n\n```sh\npnpm run demo:acp\n```\n\n## TODO markers\n\nUse one of three comment tags to flag known issues in the code, ordered by urgency:\n\n- `FIXME` — an issue that should block a new release. A release should not ship with an open `FIXME` unless reviewers explicitly agree the change can be merged anyway.\n- `TODO` — an issue that should be fixed soon, once we have the resources.\n- `XXX` — an issue that we may fix someday; lowest priority, no commitment.\n\nPick the tag that matches the urgency so anyone scanning the code can tell a release blocker from a someday-maybe.\n\n## Documenting types verbatim (`ts type-equiv`)\n\nThe [core data structures](core-data-structures/core.md) docs paste source-equivalent declarations together with their original JSDoc so a reader sees the exact shape and source contract. To keep a paste from drifting when source changes, fence it as ` ```ts type-equiv ` (instead of ` ```ts `) and register it in `scripts/type-equiv.manifest.json` with the source file and symbol it mirrors:\n\n```json\n{ \"doc\": \"docs/core-data-structures/session.md\", \"symbol\": \"SessionEvent\", \"source\": \"packages/core/session/src/types.ts\" }\n```\n\n`pnpm run verify-type-equiv` (part of `doc-sync`) then extracts that symbol's declaration and attached JSDoc from source via the TypeScript parser and asserts the block matches both. For a class whose implementation bodies do not belong in the catalog, use ` ```ts public-api ` and set `\"projection\": \"public-api\"`; the checked projection retains the public fields, constructor, accessors, methods, and original class/member JSDoc while omitting bodies and private or protected members. Comparison ignores whitespace and non-JSDoc comments but requires every original JSDoc comment, including member documentation, so readers see the source contract beside the exact shape. The gate enforces a 1:1 correspondence by document, symbol, and projection between primary blocks and manifest entries; a paired `.zh.md` block reuses its unsuffixed sibling's entry only when the whole tracked fence sequence is byte-identical and ordered identically. `doc-typecheck` applies the same derivative rule to compilable fences, while skipping both source-equivalence fence kinds from compilation and its opt-out ratio. When you change a documented declaration or its JSDoc, the gate fails until you update the paste; when you add or remove a primary block, update the manifest in the same change.\n\n## Architecture context\n\nRead `docs/architecture.md` before changing anything under `packages/`. The codebase is built around Cordis plugins, event-sourced sessions, typed service seams, and explicit extension points.\n"
+        "content": "# Development guide\n\nEnglish | [中文](development.zh.md)\n\nThis onboarding guide helps project contributors get started with the local environment, daily workflow, and CI flow; see the Agent Notes for design rationale and technical trade-offs.\n\n## Prerequisites\n\n- Node.js supports 22.19+ and 24+. CI covers 22.19, 24, and 26; see the [Node engine floor Agent Note](../.agents/notes/implemented/process/2026-07-06-node-engine-floor.md).\n- Corepack-enabled pnpm. The repo pins `pnpm@11.7.0` in `package.json`; run `corepack enable` if `pnpm --version` does not resolve through Corepack.\n- Git 2.26 or newer; hook setup enables Git's worktree-specific configuration extension.\n- Optional: a DeepSeek API key for the TUI, headless, and ACP automation demos and real-API e2e tests.\n\n## First-time setup\n\nInstall dependencies from the repo root:\n\n```sh\npnpm install\n```\n\nThe install also runs the root `postinstall` script, which installs lefthook from the repo dev dependency through `scripts/install-lefthook.mjs`. With `CI=true` or `GITHUB_ACTIONS=true`, the wrapper returns before Git discovery because automated jobs do not consume contributor hooks. Otherwise, it requires Git 2.26 or newer and gives the current worktree an explicit hook directory under its own Git directory; linked worktrees therefore use their own lefthook binary and configuration instead of rewriting common hooks. The first install enables Git's worktree-specific configuration extension and repository format 1; see the [worktree-local hooks Agent Note](../.agents/notes/implemented/process/2026-07-27-worktree-local-lefthook.md).\n\nIf hooks are missing because dependencies were restored from cache or `postinstall` was skipped, install them manually:\n\n```sh\nnode scripts/install-lefthook.mjs\n```\n\nThe wrapper refuses user-owned `core.hooksPath` values. An inherited system, global, or common-repository path requires `DSH_LEFTHOOK_ALLOW_HOOKS_PATH_OVERRIDE=1`. When Git seeds a new worktree with another registered worktree's marker-backed hook path, the wrapper replaces that copied value with the new worktree's own path; command-scoped and other worktree-scoped paths must be integrated or removed explicitly.\n\nBefore enabling worktree config, migrate direct `extensions.*` in a format-0 common config, direct `core.worktree` or `core.bare=true`, and any non-empty dormant `config.worktree`. The common config and every worktree config must be regular files, while the owned hook directory may contain only unaliased regular files.\n\nAfter moving a checkout, rerun the wrapper to relocate its owned path and regenerate hooks. For a stale or invalid installer lock, first confirm no installer is running, then remove the reported lock and retry. If installation and hook-path rollback both fail, inspect the reported worktree config before retrying. The [worktree-local hooks Agent Note](../.agents/notes/implemented/process/2026-07-27-worktree-local-lefthook.md) owns the full safety contract.\n\nRun typecheck once after a fresh clone:\n\n```sh\npnpm run typecheck\n```\n\nThat first typecheck runs the whole-repo `tsc -b` graph: it emits every package/vendor `lib/types` and checks examples, tests, and scripts through the two no-emit aggregates described below.\n\n## TypeScript project layout\n\nThe repository's TypeScript configuration has exactly three roles; every tsconfig file plays one of them.\n\n| File | Role | Forms a program? |\n|---|---|---|\n| `tsconfig.json` | Solution root: `extends` base, `files: []`, references to the two aggregates. The whole-repo `tsc -b tsconfig.json` graph, the tsserver discovery entry, and — through the inherited `paths` — the resolution config for tsx running `examples/` and `scripts/` (their nearest tsconfig is this file). | No |\n| `tsconfig.host.json` | Host aggregate: host-side packages (via references), examples, tests, scripts, website. Excludes `packages/client`. | Yes |\n| `tsconfig.client.json` | Client aggregate: `packages/client/*` packages and their tests, `apps/web`. | Yes |\n| `tsconfig.base.json` | Shared compilerOptions and the source `paths` map. Also the resolution facade the vitest configs point vite-tsconfig-paths at: it has no `include`, so its `paths` apply to every importer. | No |\n| `tsconfig.base.client.json` | Browser compiler shape (`jsx`, DOM libs, `types: []`) extended by the client aggregate and every `packages/client/*` package. | No |\n\nHost and client stay two aggregate programs because both sides declaration-merge the cordis `Context` interface under the same keys with different services; one program seeing both merges reports a collision. The collision exists only inside a `ts.Program` — module resolution never triggers it — which is why the solution may reference both aggregates and one paths facade may span both sides. Two disciplines follow:\n\n- `tsconfig.base.json` never gains `include` or `files`: they would leak into every extending package project and narrow the facade's match-all scope.\n- A script that builds a repo-wide `ts.Program` seeds `tsconfig.host.json` or `tsconfig.client.json` explicitly — never the root solution, because flattening both aggregates into one program collides the `Context` merges. Program-backed generators and gates (`scripts/ts-project.ts` consumers, doc-typecheck standalone mode) are host-only by decision; the client side gains program-backed tooling only with a concrete need.\n\nStatic analysis and tests resolve workspace imports through the base `paths` map to `src` and must pass on a clean tree; gates that consume built `lib/` output declare that dependency explicitly. Decision record: [solution-root note](../.agents/notes/implemented/process/2026-07-22-tsconfig-solution-root-two-aggregates.md); the tsc-first emit pipeline is the [ts-build-config note](../.agents/notes/implemented/process/2026-06-17-ts-build-config.md).\n\nIf a relevant local check consumes built package output, build once first:\n\n```sh\npnpm run build\n```\n\n`pnpm run hygiene` includes `publint`, which validates package entrypoints against the built `lib/*.js` files, and `verify-node-next-types`, which validates built declarations against a temporary NodeNext consumer. A fresh worktree has no bundled JS or declarations until `pnpm run build` runs; ordinary commits and pushes do not require that build unless their selected checks consume it.\n\n## Environment variables\n\nThe real DeepSeek adapter and key-backed agent demos read credentials from the environment or from a gitignored `.env` at the repo root:\n\n```sh\nDEEPSEEK_API_KEY=sk-...\nDEEPSEEK_BASE_URL=https://... # optional\n```\n\n`DEEPSEEK_BASE_URL` is optional and defaults to the public API. Never commit real credentials. The real-API e2e suites self-skip when `DEEPSEEK_API_KEY` is not set.\n\n## Git hooks\n\nlefthook is configured in `lefthook.yml` as a fast local checkpoint:\n\n- `pre-commit` applies formatting-only ESLint fixes, validates the staged files with Oxlint and applies its native fixes, checks the staged diff for whitespace errors, and runs the vendor manifest guard.\n- `pre-push` runs only the incremental repository typecheck (`tsc -b` over the root solution, covering both the host and client aggregates).\n\nThe vendor manifest guard checks that changes under `vendor/*/src` are staged with the matching `vendor/README.md` manifest update. See `vendor/README.md` before editing vendored code.\n\nThe hooks intentionally do not run tests, snapshots, documentation checks, builds, or hygiene. Contributors run the [checks relevant to the changed behavior](../AGENTS.md#run-relevant-checks-locally) once; CI owns exhaustive coverage, built-artifact smokes, and the Node 22.19, 24, and 26 compatibility matrix.\n\nContributors can opt into the comprehensive local gate set with `pnpm run check:all`. The command is independent of both Git hooks and is not an agent instruction.\n\n## CI gates\n\nThe keyless [CI workflow](../.github/workflows/ci.yml) groups independent gates into broad lanes and runs a smaller compatibility signal across supported Node versions. Artifact consumers wait for one build within their lane. The separate real-API workflow runs `pnpm run test:e2e` with its configured worker bound. See [scripts/run-gates.ts](../scripts/run-gates.ts) and the workflow files for the current gate and job inventory.\n\n## Daily commands\n\nUse these from the repo root:\n\n```sh\npnpm run test           # unit tests\npnpm run test:coverage  # unit tests with per-file coverage gates\npnpm run test:e2e       # real-API tests; self-skips without DEEPSEEK_API_KEY\npnpm run check:all      # comprehensive opt-in gate set; not wired to Git hooks\npnpm run typecheck      # tsc -b over the root solution: emits package/vendor lib/types, checks both aggregates\npnpm run lint           # oxlint .\npnpm run lint:fix       # formatting-only ESLint, then oxlint . --fix\npnpm run doc-typecheck  # compile checked TypeScript snippets in Markdown docs\npnpm run gen-cordis-catalog     # regenerate docs/cordis-catalog/events.md + services.md from source\npnpm run verify-cordis-catalog  # fail if either cordis catalog is stale\npnpm run verify-export-jsdoc    # fail if a module-level package export lacks complete JSDoc\npnpm run gen-doc-graphs     # regenerate generated relationship docs from source and curated graph definitions\npnpm run verify-doc-graphs  # fail if generated relationship docs are stale\npnpm run verify-md-wrap  # fail on hard-wrapped prose paragraphs in docs/README markdown\npnpm run verify-mermaid  # fail if a ```mermaid diagram has invalid Mermaid syntax\npnpm run verify-type-equiv  # fail if a ```ts type-equiv doc block drifts from its source type\npnpm run verify-doc-budgets  # fail if a budgeted standing doc exceeds its word ceiling\npnpm run gen-translation-brief   # print the minimal-update briefing for out-of-sync translation pairs (--apply splices code-only edits)\npnpm run doc-sync       # all Markdown/doc gates, scheduled concurrently; the doc-sync leaf list in scripts/run-gates.ts is the full list\npnpm run gen-module-graph     # regenerate docs/module-graph.md from package peerDeps\npnpm run verify-module-graph  # fail if docs/module-graph.md is stale\npnpm run build          # emit lib/types intermediates, then bundle lib/index.* runtime files\npnpm run verify-node-next-types  # fail if built declarations are not NodeNext-consumable\npnpm run hygiene        # knip, publint, workspace constraints, and NodeNext declaration check\n```\n\nWhen changing package public behavior, update the relevant README or JSDoc in the same change. `pnpm run doc-sync` catches checked TypeScript snippets, generated doc freshness, markdown wrap/link drift, type equivalence, translation pairing, Mermaid syntax, and doc budgets, but broader prose/API sync still needs review.\n\n## Demos\n\nThe one-shot Headless coding agent needs `DEEPSEEK_API_KEY` in the environment or repo-root `.env`:\n\n```sh\npnpm run demo:headless \"summarize this workspace\"\n```\n\nThe full-screen interactive coding agent needs `DEEPSEEK_API_KEY` in the environment or repo-root `.env`:\n\n```sh\npnpm run demo:tui\n```\n\nThe self-referential cordis demo can inspect and modify its live plugin runtime and needs the same credentials (`web` by default, or `acp`):\n\n```sh\npnpm run demo:cordis\n```\n\nThe ACP automation server exposes fresh agent sessions over JSON-RPC stdio and also needs `DEEPSEEK_API_KEY`:\n\n```sh\npnpm run demo:acp\n```\n\n## TODO markers\n\nUse one of three comment tags to flag known issues in the code, ordered by urgency:\n\n- `FIXME` — an issue that should block a new release.

optional\n```\n\n`DEEPSEEK_BASE_URL` 可选，默认为公开 API。请勿提交真实凭证。未设置 `DEEPSEEK_API_KEY` 时，真实 API 的 e2e 套件会自动跳过。\n\n## Git 钩子\n\nlefthook 在 `lefthook.yml` 中配置，作为快速的本地检查点：\n\n- `pre-commit` 应用仅用于格式化的 ESLint 修复，使用 Oxlint 验证暂存文件并应用其原生修复，然后检查暂存 diff 中的空白错误，并运行 vendor manifest（元数据清单）守卫；\n- `pre-push` 只运行仓库增量类型检查（对根 solution 执行 `tsc -b`，覆盖 host 与 client 两个聚合）。\n\nvendor manifest 守卫检查 `vendor/*/src` 下的改动是否连同对应的 `vendor/README.md` manifest 更新一起暂存。请在编辑 vendor 代码前先阅读 `vendor/README.md`。\n\n这些钩子有意不运行测试、快照、文档检查、构建或 `hygiene`。贡献者只运行一次[与改动行为相关的检查](../AGENTS.md#run-relevant-checks-locally)；CI 负责全量覆盖率门禁、构建产物冒烟测试，以及 Node 22.19、24 和 26 兼容性矩阵。\n\n贡献者可以选择运行 `pnpm run check:all`，执行全面的本地门禁集。该命令独立于两个 Git 钩子，也不是对 agent 的指令。\n\n## CI 门禁\n\nkeyless [CI 工作流](../.github/workflows/ci.yml) 将独立门禁分组到若干宽粒度 lane，并在受支持的 Node 版本上运行一组较小的兼容性检查。产物消费方在各自 lane 内等待一次 build。单独的真实 API 工作流按其配置的 worker 上限运行 `pnpm run test:e2e`。当前门禁和 job 清单以 [scripts/run-gates.ts](../scripts/run-gates.ts) 和工作流文件为准。\n\n## 日常命令\n\n在仓库根目录使用：\n\n```sh\npnpm run test           #

optional\n```\n\n`DEEPSEEK_BASE_URL` 可选，默认为公开 API。请勿提交真实凭证。未设置 `DEEPSEEK_API_KEY` 时，真实 API 的 e2e 套件会自动跳过。\n\n## Git 钩子\n\nlefthook 在 `lefthook.yml` 中配置，作为快速的本地检查点：\n\n- `pre-commit` 应用仅用于格式化的 ESLint 修复，使用 Oxlint 验证暂存文件并应用其原生修复，然后检查暂存 diff 中的空白错误，并运行 vendor manifest（元数据清单）守卫；\n- `pre-push` 只运行仓库增量类型检查（对根 solution 执行 `tsc -b`，覆盖 host 与 client 两个聚合）。\n\nvendor manifest 守卫检查 `vendor/*/src` 下的改动是否连同对应的 `vendor/README.md` manifest 更新一起暂存。请在编辑 vendor 代码前先阅读 `vendor/README.md`。\n\n这些钩子有意不运行测试、快照、文档检查、构建或 `hygiene`。贡献者只运行一次[与改动行为相关的检查](../AGENTS.md#run-relevant-checks-locally)；CI 负责全量覆盖率门禁、构建产物冒烟测试，以及 Node 22.19、24 和 26 兼容性矩阵。\n\n贡献者可以选择运行 `pnpm run check:all`，执行全面的本地门禁集。该命令独立于两个 Git 钩子，也不是对 agent 的指令。\n\n## CI 门禁\n\nkeyless [CI 工作流](../.github/workflows/ci.yml) 将独立门禁分组到若干宽粒度 lane，并在受支持的 Node 版本上运行一组较小的兼容性检查。产物消费方在各自 lane 内等待一次 build。单独的真实 API 工作流按其配置的 worker 上限运行 `pnpm run test:e2e`。当前门禁和 job 清单以 [scripts/run-gates.ts](../scripts/run-gates.ts) 和工作流文件为准。\n\n## 日常命令\n\n在仓库根目录使用：\n\n```sh\npnpm run test           # unit tests\npnpm run test:coverage  # unit tests with per-file coverage gates\npnpm run test:e2e       # real-API tests; self-skips without DEEPSEEK_API_KEY\npnpm run check:all      # comprehensive opt-in gate set; not wired to Git hooks\npnpm run typecheck      #

 ## Decision
 
-The dsh launcher supplies one session root under its Harness home through a boot slot, the picker gains a workspace scope, and the handoff carries the target directory.
+The shared CLI configuration supplies one session root under the Harness home, the picker gains a workspace scope, and the handoff carries the target directory.
 
-**Storage.** `dsh-paths` owns the location as `resolveSessionsRoot()` (`sessions` under the Harness home, by `resolveDshHome`'s precedence), but only the launcher assumes it: shared-store policy is the dsh CLI's, never a plugin's. The TUI surface provides the root through the `SESSIONS_ROOT_KEY` boot slot (`ctx.provide` before Loader entries mount) and `dsh web` patches the same root in `apps/cli/src/app-cli-entry.ts`. Two CLI surfaces computing that path independently is exactly the failure this change fixes — disjoint stores — so the fact gets one home rather than a `join` per caller, alongside the existing `registryRoot()` precedent for `run`.
-
-The shared base states that precedence in the row itself: `apps/cli/config/base.cordis.yml`'s `session-persistence-jsonl` row reads `root: !!js launcherSessionsRoot ?? './.sessions'`, so the launcher slot wins and a bare boot without one keeps the project-local default. Expressing it as the row's own `!!js` value rather than a schemastery `.default()` matters for the same reason it did in the bundle: a schema default would materialize before the slot could be read. An overlay or personal patch that states an explicit root always wins, which remains the correct choice for a hermetic deployment.
+**Storage.** The shared base owns the default in `apps/cli/config/base.cordis.yml`: its `session-persistence-jsonl` row resolves `sessions` beneath `DSH_HOME`, with the standard `~/.dsh` fallback when the environment has not been initialized. TUI, Web, and headless therefore consume one default without launcher patches or a boot slot. An overlay or personal patch that states an explicit root replaces that row's whole `config` and remains the deployment's authoritative choice.
 
 **Scope, not exclusion.** A workspace other than the current one is a display scope rather than a disabled reason. `showResume()` summarizes every record and the `ResumePicker` owns a `scope` of `'workspace' | 'all'`, defaulting to the current workspace so the common case is unchanged. Tab toggles; the scope line names the active scope and the count the other holds; each row in the all-workspaces scope reports its own workspace, and that label joins the searchable text only in the scope that shows it. A toggle clears the query and selection so the highlighted row always belongs to the visible list, and the per-row workspace line makes a row one terminal row taller in that scope, which the visible-count budget accounts for.
 
 `summarizeResumeCandidate` therefore drops `'different workspace'` and gains `'session has no recorded workspace'`. That is a real new refusal rather than a rename: a header without `cwd` names no directory for the host to enter, so it cannot be handed off even though its log is intact.
 
-**Handoff.** `TuiResumeHost.handoff` takes the target `cwd` beside the `SessionId`. `preflightResume` resolves both together and returns them, so the caller cannot re-derive a stale directory from the row it displayed — a record whose `cwd` moved between listing and preflight is resumed in the *re-read* directory, which is why the former "reject a moved cwd" behavior is now a handoff with the new path. The shipped host chdirs before disposing the app: an unreachable directory must reject while the caller can still restore the terminal, because after teardown no owner remains to report to. `resumeArgs` keeps the `meta` subcommand form only when the target is this checkout, since `dsh meta` chdirs to the harness source itself and would override any other workspace.
+**Handoff.** `TuiResumeHost.handoff` takes the target `cwd` beside the `SessionId`. `preflightResume` resolves both together and returns them, so the caller cannot re-derive a stale directory from the row it displayed — a record whose `cwd` moved between listing and preflight is resumed in the *re-read* directory, which is why the former "reject a moved cwd" behavior is now a handoff with the new path.

-TUI tests cover the default scope hiding other workspaces while reporting their count, Tab revealing them with per-row workspace labels, Tab back clearing the query and selection, searching by workspace label, a cwd-less record staying visible but disabled, and the handoff receiving both the id and the workspace re-read at preflight. The former "reject a moved cwd" case now asserts the handoff carries the new directory. `dsh-paths` tests pin `resolveSessionsRoot`'s precedence against `resolveDshHome`'s. `apps/cli` tests pin the project-local default and the derived `session-query.db` path.

-**存储。** `dsh-paths` 以 `resolveSessionsRoot()` 拥有该位置（按 `resolveDshHome` 的优先级，取 Harness home 下的 `sessions`），但只有启动器假定它：共享存储策略属于 dsh CLI，绝不属于插件。TUI 界面通过 `SESSIONS_ROOT_KEY` 启动槽位（在 Loader 条目挂载前 `ctx.provide`）提供该根目录，`dsh web` 则在 `apps/cli/src/app-cli-entry.ts` 中为同一根目录打补丁。CLI 的两处界面各自独立计算该路径，正是本次改动所修复的那种失败——互不相交的存储——因此这项事实只有一个归属，而不是每个调用方各做一次 `join`，这与 `run` 已有的 `registryRoot()` 先例一致。
-
-共享 base 直接在配置项自身表达这一优先级：`apps/cli/config/base.cordis.yml` 的 `session-persistence-jsonl` 配置项写作 `root: !!js launcherSessionsRoot ?? './.sessions'`，因此启动器槽位优先，而没有槽位的裸启动则保留项目本地默认值。把它写成配置项自身的 `!!js` 取值、而不是 schemastery 的 `.default()`，其原因与在组合包中相同：schema 默认值会在能够读取槽位之前就物化。若 overlay 或个人 patch 显式声明了根目录，则始终以其为准——对于要求自洽封闭的部署，这仍是正确选择。
+**存储。** 共享 base 在 `apps/cli/config/base.cordis.yml` 中拥有默认值：其 `session-persistence-jsonl` 配置项把 `sessions` 解析到 `DSH_HOME` 下；环境尚未初始化时则使用标准的 `~/.dsh` 回退值。因此 TUI、Web 与 headless 使用同一个默认值，无需启动器补丁或启动槽位。若 overlay 或个人 patch 显式声明根目录，它会整体替换该配置项的 `config`，并继续作为部署的权威选择。
 
 **是范围，不是排除。** 当前 workspace 之外的 workspace 是一种展示范围，而不是禁用理由。`showResume()` 汇总每一条记录，`ResumePicker` 持有一个 `'workspace' | 'all'` 的 `scope`，默认为当前 workspace，因此常见场景毫无变化。Tab 切换范围；范围行会说明当前生效的范围，以及另一个范围下的数量；在全 workspace 范围中每一行都报告自己的 workspace，而该标签只在展示它的范围里才加入可搜索文本。切换范围会清空查询和选中项，使高亮行始终属于可见列表；而逐行的 workspace 行会让该范围下的每一行在终端里多占一行，可见条数预算已经把这一点计入。
 
 因此 `summarizeResumeCandidate` 去掉了 `'different workspace'`，并新增 `'session has no recorded workspace'`。这是一条真正新增的拒绝理由，而不是改名：没有 `cwd` 的头部没有指明任何目录供宿主进入，所以即便它的日志完好也无法完成交接。
 
-**交接。** `TuiResumeHost.handoff` 在 `SessionId` 之外还接收目标 `cwd`。`preflightResume` 把两者一起解析并一起返回，因此调用方无法从它展示过的那一行里重新推导出一个陈旧目录——在列表展示与预检之间 `cwd` 发生了移动的记录，会在*重新读取到的*目录中恢复，这也是原先「拒绝已移动的 cwd」的行为如今变成携带新路径完成交接的原因。已交付的宿主在释放应用之前切换目录：不可达的目录必须在调用方还能恢复终端时就拒绝，因为拆卸之后已经没有任何所有者可供汇报。`resumeArgs` 只在目标就是本 checkout 时才保留 `meta` 子命令形式，因为 `dsh meta` 会切换到 harness 源码本身，从而覆盖任何其他 workspace。

 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.

Subject: [PATCH 178/212] feat(session): project the inherited-history boundary
 into the log
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A plugin owning a standalone open/close bracket cannot tell a dead marker
from a live one: an unmatched `compact/start` reads identically whether the
previous writer died mid-compaction or a compaction is running now.
`Session.firstLiveSeq` already holds that answer exactly, but only in memory.

Append the log-only `session/inherited` event at that seq from the seeded
constructor — the single waist all six seeded-start paths pass through
(resume, configured startup on a persisted id, `sessions.fork()`, a subagent
fork child, `adopt()`'s live prefix, and a bare seeded `create`). Read it
through the new `isInheritedSeq(events, seq)`.

The constructor placement means persistence needs no changes: the marker is
already in `events` when a backend captures the creation seed, so it rides
the ordinary seed path with no load-time write. It also covers fork, where
the inherited bracket's owner may still be running — the case a
persistence-layer boundary could not reach.

Activity ordering excludes the boundary through `lastActivityTime()`, since
lazy resume makes browsing a pickup and the three call sites would otherwise
float every opened session to the top of a picker or list.

+# Agent Note: the inherited-history log boundary
+
+Status: implemented
+
+English | [中文](2026-07-30-session-inherited-log-boundary.zh.md)
+
+## Problem
+
+A plugin that owns a standalone open/close bracket in the session log cannot tell a dead marker from a live one. `compact/start` … `compact/end` is the shipped case: on picking up a log whose last compaction event is an unmatched `compact/start`, "the previous writer died mid-compaction" and "a compaction is running right now" are byte-identical stored history. The owner must either refuse to compact a log that is actually free (wedging the session) or proceed over one that is genuinely busy.
+
+Nothing in the log marked where inherited history ended. `session/created`, `session/disposed`, and `session/flush` are cordis runtime signals, not log events; `agent/session-start` is emit-only. `Session.firstLiveSeq` already held the answer exactly — the seq of this lifecycle's first own write — but only in memory, so a consumer reading stored bytes could not see it.
+
+Crash repair does not close the gap and must not: `interruptedTurnClosers` synthesizes turn, step, and tool boundaries because core owns that vocabulary, and `compact/*` belongs to the compaction seam. A core repair pass that closed plugin brackets would put every plugin's bracket semantics in core.
+
+## Decision
+
+`Session`'s constructor appends the log-only `session/inherited` event as the seeded session's first live write, at the seq `firstLiveSeq` names. The event is the durable projection of that field: `firstLiveSeq` answers "which prefix did I inherit" for a consumer holding the object, the event answers it for one holding only stored bytes. Its payload is empty — position and `time` carry the whole meaning — and it is not a `SurfaceEventType`, so it produces no message and cannot perturb derived history.
+
+`isInheritedSeq(events, seq)` (exported from `dsh-session`) is the predicate a bracket owner calls on an unmatched opening marker. True means the marker belongs to a lifecycle that has ended and cannot still be running. Core writes the boundary and reads nothing from it; each bracket's vocabulary stays with its owning plugin.
+
+The constructor is the placement because it is the single waist every seeded session passes through. All six entry points reach it: `agents.resume()`, config-driven startup on a persisted id (`restoreOrCreateConfigured`), `sessions.fork()`, a subagent fork child, `coordinator.adopt()`'s live-prefix path, and a bare `sessions.create(id, {seed})`. A boundary written at persistence load would miss both fork paths — and a forked child inheriting a still-running parent's open `compact/start` is precisely the case the predicate must classify. A boundary written at loop start would miss `fork()` and `adopt()`, and would have to fire on `SessionStartSource: 'startup'`, which is what a fork child publishes, so that field would stop discriminating.
+
+Two guards keep the marker from becoming noise. An empty seed writes nothing: a boundary with nothing below it marks nothing. A seed already ending in one is not re-marked, which makes the write idempotent. Idempotence is load-bearing rather than tidiness — `agentFor()` resumes a cold session on first touch, so merely opening one in a client is a pickup, and without the guard browsing would grow a log by one event per visit.
+
+## Persistence needs no changes
+
+The marker is in `session.events` before the coordinator captures its creation seed, so it persists through the ordinary seed path — `onCreated`'s `createCore` + `appendCore`, or the ownerless-claim suffix write. No load-path write, no revision bump at load, no durable mark on a rejected `append`, and a read-only store still serves loads.
+
+Being a live event, it reaches disk through the write-behind drain (`session/event` → `live.pending` → `scheduleDrain`) rather than a synchronous commit, so a crash can lose it. That costs nothing: `pending` drains in order, so a lost boundary means every live event above it is lost too, and the next pickup reads the same bytes the previous one did, appends its own boundary, and classifies the bracket identically. In-process consumers should prefer `firstLiveSeq`, which is exact before any write.
+
+## Scope of the guarantee
+
+The predicate holds for a bracket *this* session inherited, not as a liveness signal about other writers. A concurrently live session may hold an open bracket over the same stored history while its own boundary sits elsewhere. A consumer that must tolerate concurrent writers needs a liveness signal beyond the log and cannot omit it on the strength of this event.
+
+## Alternatives considered
+
+**A boundary written by the persistence coordinator's cold-load path.** Built first, as the [`session/resumed` boundary](../../rejected/architecture/2026-07-29-session-resumed-log-boundary.md), and abandoned before merge. It covers no fork, which is the one case where the inherited bracket's owner may still be running. Because the marker was minted at load it also had to be a durable write on a read path, which spread cost across the seam: a revision bump on every cold load, a `commitRepair` batch on a balanced log with nothing to repair, a stored-time floor to keep the clamp monotonic, and a load that failed against a read-only store.
+
+**A boundary appended at loop start.** The loop is one call above `resumeWith`, so it covers the resume paths, but it misses `fork()` and `adopt()` entirely, and the event would have to fire on `'startup'` — the source a fork child publishes — so `SessionStartSource` would stop discriminating. It also publishes the session before the marker is appended, so a `session/created` listener could observe a seeded log with no boundary.
+
+**Reusing `header.seedLength`.** It is the durable *fork-lineage* boundary and deliberately keeps the original fork value across a resume, where the constructor seed is the whole stored log. The two facts differ and conflating them would lose both.
+
+**Crash repair closing `compact/*` alongside turn boundaries.** Rejected: it moves every plugin's bracket semantics into core's repair pass, and core cannot know what closing another package's bracket should record.
+
+## Consequences
+
+Bought: one predicate, in one place, correct for all six seeded-start paths — including the fork gap the persistence-layer version could not reach. The persistence packages keep a pure read path. `firstLiveSeq` gains a durable twin rather than a second, competing notion of the same boundary.
+
+Cost: a seeded session's log is one event longer, which moved seq expectations in tests across nine packages (session, agent-loop, persistence contract, jsonl, session-query, session-title, subagent-inprocess, telemetry, token-meter). Two of those updates are load-bearing rather than mechanical: telemetry's adoption tests now assert the boundary IS exported, because it is this lifecycle's own write, and the property suite's replay invariant is restated as "seed reproduced verbatim, plus one log-only boundary" with idempotence added as its own property.
+
+`session/inherited` joins the on-disk vocabulary. Under the pre-release stance (`SESSION_FORMAT_VERSION` pinned at `0`, no compatibility promise) older logs simply lack it, and a log without a boundary correctly reports nothing as inherited.
+
+Not built here: no plugin consumes `isInheritedSeq` yet. Wiring the compaction seam's staleness check to it is the follow-up that motivated this boundary, and it belongs with that seam's own tests.

+# Agent Note: 继承历史日志边界
+
+Status: implemented
+
+[English](2026-07-30-session-inherited-log-boundary.md) | 中文
+
+## Problem
+
+拥有独立开／闭括号的插件无法区分一个已死的标记和一个存活的标记。`compact/start` … `compact/end` 就是已发布的实例：当接手一份日志、而它最后的压缩事件是一个未配对的 `compact/start` 时，"上一个写入方在压缩中途死掉了"与"此刻正有一次压缩在运行"在存储历史中是逐字节相同的。所有方只能二选一：拒绝压缩一份其实空闲的日志（把会话卡死），或者在一份确实繁忙的日志上继续压缩。
+
+日志中没有任何东西标出继承历史在哪里结束。`session/created`、`session/disposed` 与 `session/flush` 是 cordis 运行时信号，不是日志事件；`agent/session-start` 只发射不落盘。`Session.firstLiveSeq` 本来就精确地持有这个答案——本生命周期第一次自有写入的 seq——但只存在于内存中，因此读取存储字节的消费方看不到它。
+
+崩溃修复既没有填上这个缺口，也不应该去填：`interruptedTurnClosers` 合成轮次、步骤与工具边界，是因为核心拥有那套词汇表，而 `compact/*` 属于压缩 seam。一个会关闭插件括号的核心修复流程，等于把每个插件的括号语义都搬进核心。
+
+## Decision
+
+`Session` 的构造函数把仅日志事件 `session/inherited` 作为带种子会话的第一次实时写入追加，位置正是 `firstLiveSeq` 指出的 seq。该事件是那个字段的持久投影：`firstLiveSeq` 为持有对象的消费方回答"我继承了哪一段前缀"，该事件则为只持有存储字节的消费方回答同一问题。它的 payload 为空——位置与 `time` 承载全部含义——并且不是 `SurfaceEventType`，因此不产生消息，也无法扰动派生历史。
+
+`isInheritedSeq(events, seq)`（由 `dsh-session` 导出）是括号所有方在一个未配对开启标记上调用的谓词。为真意味着该标记属于一个已结束的生命周期，不可能仍在运行。核心写入该边界但不从中读取任何内容；每个括号的词汇表仍归其所属插件。
+
+选择构造函数，是因为它是每一个带种子会话都必经的唯一收窄处。全部六个入口都会到达它：`agents.resume()`、在已持久化 id 上的配置驱动启动（`restoreOrCreateConfigured`）、`sessions.fork()`、子代理 fork 子会话、`coordinator.adopt()` 的实时前缀路径，以及裸的 `sessions.create(id, {seed})`。在持久化加载时写入的边界会漏掉两条 fork 路径——而一个继承了仍在运行的父会话开放 `compact/start` 的 fork 子会话，恰恰是该谓词必须判定的场景。在 loop 启动时写入的边界会漏掉 `fork()` 与 `adopt()`，并且不得不在 `SessionStartSource: 'startup'` 上触发——那正是 fork 子会话发布的取值，于是该字段将不再具有区分力。
+
+两条守卫让这个标记不至于变成噪声。空种子不写入任何内容：下方什么都没有的边界标记不了任何东西。种子本身已以该事件结尾时不会重复标记，这让写入具备幂等性。幂等性是承重的，而不是为了整洁——`agentFor()` 会在首次触碰时恢复一个冷会话，因此在客户端里仅仅打开一个会话就是一次接手；没有这条守卫，浏览会让日志每访问一次就增长一个事件。
+
+## 持久化无需任何改动
+
+协调器捕获创建种子时该标记已在 `session.events` 中，因此它通过普通的种子路径落盘——`onCreated` 的 `createCore` + `appendCore`，或无主认领的后缀写入。没有加载路径写入、加载时没有 revision 递增、被拒绝的 `append` 不留下持久标记，只读存储依然可以服务加载。
+
+作为实时事件，它经由后写式 drain（`session/event` → `live.pending` → `scheduleDrain`）而不是同步提交到达磁盘，因此崩溃可能丢掉它。这没有代价：`pending` 按序 drain，所以丢掉一个边界意味着它上面的每个实时事件也一起丢掉，而下一次接手读到的字节与上一次相同，会追加自己的边界，并对括号作出完全相同的判定。进程内消费方应优先使用 `firstLiveSeq`，它在任何写入之前就是精确的。
+
+## 保证的适用范围
+
+该谓词对*本*会话继承的括号成立，而不是关于其他写入方的存活信号。一个并发存活的会话可能在同一段存储历史上持有开放括号，而它自己的边界在别处。必须容忍并发写入方的消费方需要日志之外的存活信号，不能仅凭这个事件就省掉它。
+
+## Alternatives considered
+
+**由持久化协调器的冷加载路径写入边界。** 最先实现的方案，即 [`session/resumed` 边界](../../rejected/architecture/2026-07-29-session-resumed-log-boundary.md)，在合并前被放弃。它完全覆盖不到 fork，而 fork 恰恰是继承括号的所有方可能仍然存活的那一种情形。由于标记是在加载时铸造的，它还必须在读取路径上做持久写入，这把成本铺开到整个 seam：每次冷加载都递增 revision、对一份无需修复的平衡日志也要走 `commitRepair`、需要一个已存储时间下限来维持钳制的单调性，以及加载在只读存储上会失败。
+
+**在 loop 启动时追加边界。** loop 位于 `resumeWith` 上一层，因此覆盖恢复路径，但完全漏掉 `fork()` 与 `adopt()`，而且事件不得不在 `'startup'` 上触发——那是 fork 子会话发布的来源——于是 `SessionStartSource` 将不再具有区分力。它还会在追加标记之前就发布会话，因此 `session/created` 监听方可能观察到一份没有边界的带种子日志。
+
+**复用 `header.seedLength`。** 它是持久的 *fork 血缘*边界，并且刻意在恢复时保留原始 fork 取值——而恢复时构造种子是整份存储日志。这两个事实并不相同，混同会同时失去两者。
+
+**让崩溃修复连同轮次边界一起关闭 `compact/*`。** 否决：这会把每个插件的括号语义搬进核心的修复流程，而核心无法知道关闭另一个包的括号应该记录什么。
+
+## Consequences
+
+买到的：一个谓词，位于一处，对全部六条带种子启动路径都正确——包括持久化层方案触及不到的 fork 缺口。持久化各包保留纯读取路径。`firstLiveSeq` 获得一个持久孪生体，而不是关于同一边界的第二套彼此竞争的概念。
+
+代价：带种子会话的日志长了一个事件，这在九个包（session、agent-loop、持久化契约、jsonl、session-query、session-title、subagent-inprocess、telemetry、token-meter）里挪动了 seq 期望。其中两处更新是承重的而非机械的：telemetry 的收养测试现在断言该边界*会*被导出，因为它是本生命周期的自有写入；而属性测试套件的重放不变式被重述为"种子逐字节复现，外加一个仅日志边界"，并把幂等性补成一条独立属性。
+
+`session/inherited` 加入了落盘词汇表。在预发布立场下（`SESSION_FORMAT_VERSION` 固定为 `0`，不作兼容承诺），更旧的日志只是没有它，而没有边界的日志会正确地报告没有任何内容被继承。
+
+此处未做：还没有任何插件消费 `isInheritedSeq`。把压缩 seam 的陈旧性检查接到它上面，是催生这条边界的后续工作，应当与那个 seam 自己的测试一起完成。

+# Agent Note: Record last activity in the session index
+
+Status: proposed
+
+English | [中文](2026-07-29-durable-last-activity-index.zh.md)
+
+## Problem
+
+A cold (persisted, unattached) session has no stored answer to "when was this last worked in". `dsh-host-apiproxy`'s `summarizeCold()` therefore approximates it with the log file's mtime where one exists — `locate()` resolves a per-session artifact for JSONL and `undefined` for SQLite, whose cold sessions fall back to `createdAt` — and the web client sorts its session tree by the resulting `updatedAt`. The two backends are wrong in opposite directions: JSONL reads too new, SQLite too old.
+
+mtime answers a different question: when the artifact was last written. Every durable write refreshes it, including writes that are not activity — a truncate-repair of a torn tail, the synthetic closers that balance an interrupted turn, and the [`session/inherited` boundary](../../implemented/architecture/2026-07-30-session-inherited-log-boundary.md) a seeded session appends. (A `flush` with nothing pending is not among them: the coordinator returns without reaching the backend.) The visible consequence is stable and wrong in one direction: a session touched without being worked in promotes itself above sessions the user actually worked in afterwards, and each touch re-promotes it. "Touched" is broader than "resumed" — `dsh-host-apiproxy`'s `agentFor()` resumes a cold session on first touch, and `sessions.history` reaches it when the web client merely opens one, so ordinary browsing is enough.
+
+The attached projection has a real fix — `lastActivityTime()` skips boundaries — but it needs the event log, and the cold path deliberately does not read one. Reading the log to compute `updatedAt` would defeat the header-only listing that keeps `list()` scaling with session count rather than log size.
+
+The boundary change raised the frequency of this defect and documented it as a known limitation on `dsh-host-apiproxy`. It did not introduce the approximation, and removing the approximation is a durable-format decision, which is why it is scoped here rather than there.
+
+## Proposal
+
+Store last-activity time where a listing already reads — the session index — so `summarizeCold()` can serve it without opening the log. The coordinator computes the value, because it sees every append and already owns per-id state; backends persist it. That makes it a new `PersistenceBackend` contract element rather than backend-local bookkeeping, and keeps one definition of "activity" shared with the in-log `lastActivityTime()`.
+
+The two shipped backends have opposite constraints, and the proposal is deliberately asymmetric about them:
+
+- **SQLite** gets a column on `sessions`, written in the same transaction as `appendBatch`, at the cost of a monotonic `SCHEMA_VERSION` bump.
+- **JSONL cannot host a mutable header field.** The header is line 1, written once during materialization, and the log is opened for append forever after; `jsonl.spec.ts` pins that committed bytes are never rewritten. A per-append header field would violate an asserted durability invariant, not merely complicate the writer. A per-session sidecar file is the shape to compare against leaving JSONL approximate.
+
+Three questions must be answered before implementation, and none of them is settled here:
+
+**Which events count as activity?** `lastActivityTime()` answers this for the log by excluding `session/inherited`. A stored field encodes the rule at write time, where the writer sees one batch rather than the whole log. The two must not drift, or the attached and cold surfaces will disagree about the same session.
+
+**How do pre-field logs behave?** Existing artifacts have no value. Falling back to mtime keeps them at today's accuracy; falling back to `createdAt` is honest but reorders every existing session in the picker and the tree.
+
+**Is a sidecar acceptable for JSONL?** It reintroduces a second file per session that can disagree with the log, which the single-artifact design avoided.
+
+## Alternatives considered
+
+**Read the log on the cold path.** Correct by construction and needs no format change, but it defeats the header-only listing: `list()` would scale with total log size, and the web session tree fans out over every session in the store. This is the option the mtime approximation exists to avoid.
+
+**Keep mtime and exclude boundary writes from it.** Rejected as impossible rather than undesirable: mtime is the filesystem's, not the backend's. Nothing short of restoring the timestamp after every boundary write would preserve it, and that races any concurrent reader and lies about the artifact.
+
+**Write the boundary only when repair occurred.** Would reduce the frequency, and the [boundary note](../../implemented/architecture/2026-07-30-session-inherited-log-boundary.md) already rejected it: the predicate must hold for an orderly restart too. Trading a correctness invariant for timestamp accuracy is the wrong direction.
+
+**Derive activity from a projection cache.** `session-projection-cache` already folds tails past a watermark, so a last-activity unit would ride existing machinery. Rejected as the primary shape because the cache is an optional composition entry; a listing served only when a cache plugin is mounted makes ordering depend on composition.
+
+## Acceptance criteria
+
+- `SessionSummary.updatedAt` for a cold session equals the same value the attached projection reports for that session, verified by resuming, quitting without a turn, and asserting the order is unchanged across both paths.
+- A resumed-then-abandoned session does not sort above a session worked in afterwards, in the web session tree and the TUI resume picker, pinned by an assembled snapshot rather than unit tests alone.
+- The activity rule has one definition: a test proves the stored field and `lastActivityTime()` agree over a log containing boundaries, closers, and a plain turn.
+- Pre-field artifacts load and list without error under the chosen fallback, with the fallback's ordering consequence asserted.
+- SQLite's `SCHEMA_VERSION` bump rejects the old on-disk version per the repo's no-migration stance.
+
+## Risks
+
+**Two definitions of activity drift.** The stored field is computed per batch, the projection over a whole log. A new event type classified one way at write time and the other at read time yields a session whose cold and attached orderings disagree — a bug that only appears after a restart, which is where it is hardest to notice.
+
+**A JSONL sidecar can disagree with its log.** A crash between the log append and the sidecar write leaves a stale value with no torn-tail marker to repair it. Every consumer would need to treat the sidecar as a hint, which is close to what mtime already is.
+
+**The fallback reorders existing sessions.** Whichever fallback is chosen, users with existing logs see their picker and tree reorder once on upgrade. `createdAt` makes that reordering large.
+
+**Cost may exceed the defect.** The defect is a misordering of abandoned sessions. If the honest answer for JSONL is "keep the approximation", this note's outcome may be documenting that decision rather than implementing a field — and that is an acceptable outcome.

+# Agent Note: 在会话索引中记录最后活动
+
+Status: proposed
+
+[English](2026-07-29-durable-last-activity-index.md) | 中文
+
+## 问题
+
+一个冷会话（已持久化、未附加）对「上次是什么时候在这里面工作过」没有任何已存储的答案。因此 `dsh-host-apiproxy` 的 `summarizeCold()` 在存在日志文件时用它的 mtime 来近似它——`locate()` 为 JSONL 解析出一个逐会话产物，为 SQLite 解析出 `undefined`，而 SQLite 的冷会话会回退到 `createdAt`——而 web 客户端就按由此得到的 `updatedAt` 为自己的会话树排序。这两个后端错的方向正好相反：JSONL 读出来偏新，SQLite 偏旧。
+
+mtime 回答的是另一个问题：这份产物上次是什么时候被写入的。每一次持久写入都会刷新它，包括那些并不是活动的写入：一次对撕裂尾部的截断修复、用来平衡被中断的轮次的那些合成 closer，以及带种子的会话会追加的 [`session/inherited` 边界](../../implemented/architecture/2026-07-30-session-inherited-log-boundary.md)。（没有待处理内容的 `flush` 不在其中：协调器在到达后端之前就返回了。）用户可见的后果是稳定的，而且只朝一个方向错：一个被触碰过却没有在里面工作过的会话，会把自己排到用户此后真正工作过的那些会话之前，而且每次触碰都会重新把它排上去一次。「触碰」比「恢复」的范围更宽——`dsh-host-apiproxy` 的 `agentFor()` 会在首次触碰时恢复一个冷会话，而 web 客户端仅仅打开一个会话时 `sessions.history` 就会到达它，因此普通的浏览就够了。
+
+已附加会话的那个投影有真正的修复办法（`lastActivityTime()` 会跳过边界），但它需要事件日志，而冷路径有意不去读日志。为计算 `updatedAt` 而读取日志，会让只读 header 的列举失去意义，而正是它让 `list()` 的开销随会话数量而非日志体量增长。
+
+边界那次变更提高了这个缺陷的出现频率，并把它作为一项已知限制记录在 `dsh-host-apiproxy` 上。它并没有引入这套近似做法，而移除这套近似是一项持久格式决策，因此它的范围划在本文，而不是那里。
+
+## 提案
+
+把最后活动时间存到列举本就会读取的地方，也就是会话索引，这样 `summarizeCold()` 无需打开日志就能给出答案。该值由协调器计算，因为它看得到每一次追加，而且本就拥有每 id 状态；由后端负责持久化。这样它就成为 `PersistenceBackend` 契约中新增的一个要素，而不是各后端本地的账目，同时让「活动」只保留一个定义，与日志内的 `lastActivityTime()` 共用。
+
+两个已交付的后端受到的约束正好相反，本提案对它们有意采取不对称的处理：
+
+- **SQLite** 在 `sessions` 表上得到一列，与 `appendBatch` 在同一个事务中写入，代价是一次单调的 `SCHEMA_VERSION` 递增。
+- **JSONL 无法承载一个可变的 header 字段。** header 就是第 1 行，在物化时一次写就，此后这份日志永远以追加方式打开；`jsonl.spec.ts` 钉住了「已提交的字节绝不重写」。一个每次追加都要改的 header 字段，违反的是一条被断言的持久性不变式，而不只是让写入方变复杂。要与「让 JSONL 保持近似」相比较的形态，是每会话一个伴随文件。
+
+实现之前必须回答三个问题，本文对它们都没有定论：
+
+**哪些事件算作活动？** 对日志而言，`lastActivityTime()` 通过排除 `session/inherited` 回答了这个问题。一个已存储字段是在写入时编码这条规则的，而写入方在那里只看到一个批次，不是整份日志。两者不得发生漂移，否则已附加表层与冷表层会对同一个会话给出彼此矛盾的答案。
+
+**该字段引入之前的日志表现如何？** 既有产物里没有这个值。回退到 mtime 能让它们保持今天的准确度；回退到 `createdAt` 是诚实的，但会把选择器和会话树里每一个既有会话都重新排一次序。
+
+**对 JSONL 来说伴随文件可以接受吗？** 它重新引入了每会话第二个文件，而该文件可能与日志不一致，这正是单产物设计所避开的。
+
+## 考虑过的替代方案
+
+**在冷路径上读取日志。** 它按构造就是正确的，也不需要改动格式，但会让只读 header 的列举失去意义：`list()` 的开销将随日志总体量增长，而 web 会话树会扇出到存储中的每一个会话。mtime 近似的存在，正是为了避开这个选项。
+
+**保留 mtime，但把边界的写入排除在它之外。** 否决的理由是做不到，而不是不合意：mtime 属于文件系统，不属于后端。除了在每次边界写入之后把时间戳复原，没有别的办法能保住它，而那样做会与任何并发读取方产生竞态，也会对这份产物撒谎。
+
+**仅在确实发生了修复时才写入边界。** 这能降低出现频率，而[边界 Agent Note](../../implemented/architecture/2026-07-30-session-inherited-log-boundary.md)已经否决过它：谓词对有序重启同样必须成立。用一条正确性不变式去换时间戳的准确度，方向是错的。
+
+**从投影缓存派生活动时间。** `session-projection-cache` 本就会折叠水位线之后的尾部，因此一个最后活动单元可以搭乘既有机制。它作为主形态被否决，因为该缓存是一个可选的组合项；只有挂载了缓存插件才提供的列举，会让排序取决于如何组合。
+
+## 验收标准
+
+- 冷会话的 `SessionSummary.updatedAt` 等于已附加会话的投影为同一个会话报告的那个值；验证方式是恢复、不跑轮次就退出，并断言两条路径上的顺序都没有变化。
+- 在 web 会话树和 TUI 恢复选择器中，一个恢复后即被弃置的会话不会排到此后工作过的会话之前；由一份组装后的快照钉住，而不是只靠单元测试。
+- 活动规则只有一个定义：一个测试证明，在一份同时包含边界、closer 和一个普通轮次的日志上，已存储字段与 `lastActivityTime()` 的结果一致。
+- 在选定的回退方案下，该字段引入之前的产物能够无错误地加载和列举，并且该回退在排序上的后果有断言覆盖。
+- 按本仓库不做迁移的立场，SQLite 的 `SCHEMA_VERSION` 递增会拒绝旧的磁盘版本。
+
+## 风险
+
+**「活动」的两个定义发生漂移。** 已存储字段按批次计算，而投影在整份日志上计算。一种新事件类型若在写入时按一种方式归类、在读取时按另一种方式归类，就会产生一个冷排序与已附加排序彼此矛盾的会话；这个缺陷只在重启之后才显现，而那正是最难被注意到的地方。
+
+**JSONL 的伴随文件可能与它的日志不一致。** 在日志追加与伴随文件写入之间发生崩溃，会留下一个陈旧的值，而且没有撕裂尾部标记可用来修复它。每个消费方都得把伴随文件当作一条提示来对待，而这与 mtime 今天的地位已经很接近了。
+
+**回退方案会让既有会话重新排序。** 无论选定哪种回退，持有既有日志的用户都会在升级时看到自己的选择器和会话树重新排一次序。选 `createdAt` 会让这次重排的幅度很大。
+
+**代价可能超过这个缺陷本身。** 该缺陷是被弃置会话的排序出错。如果对 JSONL 来说诚实的答案是「保留这套近似」，那么本文的结局可能是记录下这个决定，而不是实现一个字段，而这也是一个可以接受的结局。

+# Agent Note: Record the resume process boundary in the session log
+
+Status: rejected — the boundary belongs at the seeded-`Session` constructor, which also covers fork and replay; superseded by [the inherited-history boundary](../../implemented/architecture/2026-07-30-session-inherited-log-boundary.md)
+
+English | [中文](2026-07-29-session-resumed-log-boundary.zh.md)
+
+## Problem
+
+A session's durable log gave no evidence that it had changed processes. `session/created`, `session/disposed`, and `session/flush` are cordis runtime signals rather than `SessionEventMap` members, and `agent/session-start` carries a `SessionStartSource` but is emit-only and never logged. Reading a stored log therefore gave no hint that anything had been resumed.
+
+That gap makes one class of question unanswerable. A plugin that owns a standalone open/close pair in the log — compaction's `compact/start` … `compact/end` is the only one today — must distinguish an unmatched opening marker left by a process that died mid-operation from one an operation is holding right now. Those two states are **byte-identical in stored history**. Without a boundary the owner has to choose between refusing forever (an unmatched marker wedges the operation permanently, and because automatic compaction failure is warn-and-continue the user-visible result is that compaction silently stops working until the context window overflows) and proceeding always (which defeats the point of holding a lock).
+
+The pressure to fix this is immediate: moving `compact/start` to its real time point, before summarization, widens the crash window from a few microseconds of synchronous appends to the length of a whole model call, so orphaned brackets go from rare to routine.
+
+## Proposal
+
+`@deepseek-ai/dsh-session-persistence` declares one log-only `session/resumed` with an empty payload and appends exactly one at the end of every cold load, in the same `commitRepair` batch as any crash-repair closers and positioned after them — so every event below the boundary was written by a writer that is no longer tracking this log. Ownership lands narrowly on `loadCore()`, the cold-load path reached by `load()` and by `adopt()`. `loadLiveSnapshot()` appends nothing, and the non-mutating `inspect()`/`readFrom()` reads never write one.
+
+The predicate a bracket owner evaluates is purely a function of the log: an unmatched opening marker with a `session/resumed` after it is stale, and one with no `session/resumed` after it is live.
+
+`time` is `Date.now()` floored at the log's greatest `time`, deliberately unlike the synthetic closers, which reuse the last real event's timestamp so repair output stays a deterministic function of stored history. The wall clock is not monotonic — an NTP step, a VM restore, or a log copied from a machine that was ahead can put it behind events already stored — so the floor keeps every cross-boundary duration non-negative. The floor is durable, because the clamped boundary is stored and joins the log's maximum: one future-dated event pins every later boundary in that log to the same instant until wall time passes it.
+
+**The predicate distinguishes process succession, not concurrent writers.** `load()`'s liveness guard is `ctx.sessions.get(id)`, which only sees sessions live in *this* runtime, and no backend takes a cross-process per-session lock. So process B cold-loading a session A currently owns writes a boundary after A's still-open bracket. A consumer that must tolerate concurrent writers still needs a liveness signal beyond the log.
+
+## Why this was rejected
+
+Two reasons, found while reviewing where the marker belonged.
+
+**It covers no fork.** `sessions.fork()` and a subagent fork child construct a seeded session without touching persistence, so neither gets a boundary. A forked child inherits its parent's prefix verbatim — including an open `compact/start` the parent is still holding — which is the one case where the inherited bracket's owner is demonstrably alive. The predicate was unavailable exactly where it was most needed.
+
+**Minting the marker at load made a read path a durable write.** Every consequence the review surfaced traced to that: a revision bump on every cold load, a `commitRepair` batch on a balanced log with nothing to repair, the durable time floor above, a load that fails against a read-only store, and a marked log after a resume the caller then cancelled. None of these are wrong given the placement; they are the placement's cost.
+
+The successor keeps the problem statement and the concurrent-writer scope limit unchanged, and moves the write to `Session`'s constructor — the single waist all six seeded-start paths pass through, fork included. Because the marker then rides the ordinary seed-persistence path, the whole durable-write surface above disappears.
+
+## Alternatives considered
+
+**Use `Session.firstLiveSeq` as the staleness predicate.** Dismissed here on the grounds that it is documented as deliberately not persisted, so the same stored log yields different answers in different processes and a read-only reader cannot evaluate it at all. That reasoning was sound about the field and wrong about the conclusion: the fix is to persist a projection of it rather than to compute the boundary somewhere else. This is the alternative that became the successor.
+
+**Declare the event in core (`dsh-session`).** Rejected here because "the constructor cannot distinguish resume from fork or replay." That is true and turned out not to matter — the distinction is not needed, since inherited history is dead history in all three cases.
+
+**Teach `interruptedTurnClosers` to close `compact/*`.** Rejected: `compact/*` is plugin-owned vocabulary and core must not know it. Core closes turn, step, and tool boundaries — the relations it owns. The successor keeps this rejection.
+
+**Lazy self-repair: the owner appends a synthetic closing marker when it finds an orphan.** A write inside a read-shaped check, and it needs an invariant exception for a numbered owner whose turn has already closed.
+
+**A merge-extensible repair-contributor registry in core.** The right shape once a second consumer exists; with one consumer today, `packages/AGENTS.md` says not to split a seam preemptively.
+
+**Write the boundary only when repair actually occurred.** Rejected: the predicate must hold for an orderly restart too, where there is nothing to repair. The successor keeps this rejection.
+
+## Related
+
+The cold-session `updatedAt` skew this proposal documented is scoped in [the last-activity-index Agent Note](../../proposed/architecture/2026-07-29-durable-last-activity-index.md). That defect predates this proposal and survives its rejection: it is caused by mtime counting every durable write, not by any one boundary.

+# Agent Note: 在会话日志中记录恢复的进程边界
+
+Status: rejected — 边界应当落在带种子 `Session` 的构造函数上，那里同时覆盖 fork 与回放；由[继承历史边界](../../implemented/architecture/2026-07-30-session-inherited-log-boundary.md)取代
+
+[English](2026-07-29-session-resumed-log-boundary.md) | 中文
+
+## Problem
+
+会话的持久日志此前无法证明它换过进程。`session/created`、`session/disposed` 和 `session/flush` 是 cordis 运行时信号，而不是 `SessionEventMap` 成员；`agent/session-start` 虽然携带 `SessionStartSource`，却只用于 emit，从不记录。因此，读取一份已存储日志得不到任何关于「曾经发生过恢复」的线索。
+
+这一空缺让一类问题无法回答。在日志中拥有独立开始／结束事件对的插件必须区分两种未匹配的起始标记：一种由某个在操作中途死亡的进程留下，另一种正被当前某项操作持有；今天符合这一形态的只有压缩的 `compact/start` … `compact/end`。这两种状态**在已存储历史中逐字节相同**。没有边界，所有方只能在两种做法之间选择：永远拒绝（一个未匹配的标记会永久卡住该操作，而自动压缩失败采取警告并继续的策略，因此用户可见的结果是压缩静默停止工作，直到上下文窗口溢出），或者始终继续（这让持有锁失去了意义）。
+
+修复它的压力是即刻的：把 `compact/start` 移到摘要生成之前这个真实的时间点，会把崩溃窗口从几微秒的同步追加扩大为一整次模型调用的时长，孤儿括号也就从罕见变为常态。
+
+## Proposal
+
+`@deepseek-ai/dsh-session-persistence` 声明唯一一个纯日志事件 `session/resumed`，其载荷为空，并在每次冷加载结束时恰好追加一条：与崩溃修复产生的 closers 同处一个 `commitRepair` 批次，且排在它们之后。因此，该边界之下的每个事件都是由一个不再追踪这份日志的写入方写下的。所有权狭窄地落在 `loadCore()`，也就是 `load()` 与 `adopt()` 到达的冷加载路径。`loadLiveSnapshot()` 不追加任何内容，非变更性的 `inspect()`／`readFrom()` 读取也从不写入。
+
+括号所有方求值的谓词纯粹是日志的函数：未匹配的起始标记之后有 `session/resumed` 的就是陈旧的，之后没有的就是存活的。
+
+`time` 取 `Date.now()` 并以日志的最大 `time` 为下限，刻意区别于合成 closers——后者复用最后一个真实事件的时间戳，以便修复输出始终是已存储历史的确定性函数。挂钟并非单调：一次 NTP 跳变、一次虚拟机恢复，或一份从走快的机器上拷来的日志，都可能让它落在已存储事件之后，因此这个下限让跨边界的时长都非负。该下限是持久的，因为被钳制的边界本身会被存储并加入日志的最大值：一个未来时间的事件会把该日志中之后的每个边界都钉在同一时刻，直到挂钟时间越过它。
+
+**该谓词区分的是进程接替，不是并发写入方。** `load()` 的存活性守卫是 `ctx.sessions.get(id)`，它只看到*本*运行时中存活的会话，而且没有任何后端会取跨进程的按会话锁。因此，进程 B 冷加载一个 A 当前拥有的会话时，会在 A 仍然开放的括号之后写入一个边界。必须容忍并发写入方的消费方仍然需要日志之外的存活信号。
+
+## 为什么被否决
+
+两个原因，都是在复审标记应当落在何处时发现的。
+
+**它完全覆盖不到 fork。** `sessions.fork()` 与子代理 fork 子会话在不触及持久化的情况下构造带种子会话，因此两者都拿不到边界。fork 子会话会逐字节继承父会话的前缀——包括父会话仍然持有的开放 `compact/start`——而这恰恰是继承括号的所有方明显还活着的唯一情形。谓词偏偏在最需要它的地方不可用。
+
+**在加载时铸造标记，把读取路径变成了持久写入。** 复审暴露出的每一项后果都源于此：每次冷加载都递增 revision、对一份无需修复的平衡日志也要走 `commitRepair`、上文那个持久时间下限、加载在只读存储上会失败，以及调用方随后取消的恢复也已留下标记。这些在该放置方式下都不算错，它们就是该放置方式的成本。
+
+取代方案保留问题陈述与并发写入方的适用范围限制不变，并把写入移到 `Session` 的构造函数——全部六条带种子启动路径（含 fork）必经的唯一收窄处。由于标记随后走普通的种子持久化路径，上述整个持久写入面就消失了。
+
+## Alternatives considered
+
+**用 `Session.firstLiveSeq` 作为陈旧性谓词。** 此处以「文档明确它有意不做持久化，因此同一份已存储日志在不同进程中会给出不同答案，而只读读取方根本无法对它求值」为理由否决。这个推理对字段本身是成立的，但结论错了：正确的修法是持久化它的一个投影，而不是把边界挪到别处去算。这条替代方案正是后来的取代方案。
+
+**在核心（`dsh-session`）中声明该事件。** 此处以「构造函数无法把恢复与 fork 或回放区分开」为理由否决。这句话是对的，但事实证明它无关紧要——并不需要这种区分，因为在这三种情形下继承历史都是死历史。
+
+**教 `interruptedTurnClosers` 关闭 `compact/*`。** 否决：`compact/*` 是插件所属词汇，核心不得知道它。核心只关闭轮次、步骤和工具边界，也就是它自己拥有的关系。取代方案保留这条否决。
+
+**惰性自修复：所有方发现孤儿时自行追加一条合成的关闭标记。** 这是在一次形似读取的检查中执行写入，而且需要为一个带轮次编号、其轮次却已经关闭的所有方开一个不变式例外。
+
+**在核心中建一个可合并扩展的修复贡献方注册表。** 一旦出现第二个消费方，这就是正确的形状；今天只有一个消费方，而 `packages/AGENTS.md` 要求不要预先拆分 seam。
+
+**仅在确实发生了修复时才写入边界。** 否决：该谓词对有序重启同样必须成立，而那时没有任何东西需要修复。取代方案保留这条否决。

 The optional `dsh-session/invariant` companion enforces the relations owned by core: turn and step numbering, execution-event enclosure, and same-step tool call/result pairing. Merge-extensible event relations belong to the plugin that declares them, so core does not reject an unknown event merely because no turn is open. See [the standalone-event decision](../../.agents/notes/implemented/simplification/2026-07-28-remove-synthetic-log-only-turns.md).
 
+## The inherited-history boundary: `session/inherited`
+
+A seeded session — resume, fork, or replay — appends this log-only event as its first live write, at the seq its `firstLiveSeq` names. It is the durable projection of that field: `firstLiveSeq` answers "which prefix did I inherit" for a consumer holding the object, this event for one holding only stored bytes. The payload is empty, so position and `time` carry the whole meaning, and it produces no message. An empty seed writes nothing, and a seed already ending in one is not re-marked, so reopening an untouched session does not grow its log per open.
+
+It exists because inherited history and live work are otherwise byte-identical, which defeats any plugin owning a standalone open/close bracket: an unmatched `compact/start` reads the same whether the writer crashed mid-compaction or is compacting right now. `isInheritedSeq(events, seq)` is the predicate a bracket owner calls — true means the opening marker belongs to an ended lifecycle, whatever ended it (a crash, a succeeding process, or a fork out of a still-running parent). It classifies only brackets *this* session inherited: a concurrently live session holding an open bracket over the same history has its own boundary elsewhere, so tolerating concurrent writers needs a liveness signal beyond the log. Core writes the boundary and reads nothing from it — a bracket's vocabulary stays with its owning plugin, which is why crash repair closes turn/step/tool boundaries and never `compact/*`.
+
+Activity ordering excludes the boundary through `lastActivityTime(events)`: picking a session up is not work, and lazy resume means browsing writes one, so a resume picker or session list ordering by log tail would float every opened session to the top.
+
 ## Plugin-contributed log-only events
 
 A plugin may declaration-merge extra `SessionEventMap` types. These are **log-only**: NOT `SurfaceEventType`s (they carry no `surfaceOp` and contribute nothing to derived history). Their owner decides whether they belong to an open execution turn or may stand between turns, and enforces any relation in its own invariant companion. The full per-event enumeration — core and plugin-contributed alike, with payloads and provenance — is the generated [persistence log event catalog](../persistence-catalog.md); the compaction seam's `compact/*` semantics are discussed on [compaction.md](compaction.md).

 可选的 `dsh-session/invariant` 配套插件会强制核心拥有的关系：轮次与步骤编号、执行事件封闭，以及同一步骤内的工具调用／结果配对。可合并扩展事件的关系由声明它的插件拥有，因此核心不会仅因没有开放轮次就拒绝未知事件。见[独立事件决策](../../.agents/notes/implemented/simplification/2026-07-28-remove-synthetic-log-only-turns.md)。
 
+## 继承历史边界：`session/inherited`
+
+带种子的会话（恢复、fork 或重放）把这个仅日志事件作为自己的第一次实时写入追加，位置正是 `firstLiveSeq` 指出的 seq。它是该字段的持久投影：`firstLiveSeq` 为持有对象的消费方回答"我继承了哪一段前缀"，这个事件则为只持有存储字节的消费方回答同一问题。payload 为空，因此位置与 `time` 承载全部含义，且不产生任何消息。空种子不写入任何内容；种子本身已以该事件结尾时不会重复标记，因此重新打开一个未被改动的会话不会每次打开都增长日志。
+
+它之所以必要，是因为继承历史与实时工作在字节层面完全相同，这会让任何拥有独立开／闭括号的插件失效：一个未配对的 `compact/start`，无论写入方是在压缩中途崩溃、还是此刻正在压缩，读起来都一样。`isInheritedSeq(events, seq)` 就是括号所有方调用的谓词——为真意味着该开启标记属于一个已结束的生命周期，无论结束原因为何（崩溃、进程接替，或从仍在运行的父会话 fork 出来）。它只判定*本*会话继承的括号：另一个并发存活的会话可能在同一段历史上持有开放括号，而它自己的边界在别处，因此容忍并发写入方还需要日志之外的存活信号。核心写入该边界但不从中读取任何内容——括号的词汇表仍归其所属插件，这也正是崩溃修复只关闭轮次／步骤／工具边界而从不处理 `compact/*` 的原因。
+
+活动排序通过 `lastActivityTime(events)` 排除该边界：接手会话不算工作，而惰性恢复意味着浏览就会写入一个，因此按日志尾部排序的恢复选择器或会话列表会把每个打开过的会话顶到最前。
+
 ## 插件贡献的仅日志事件
 
 插件可以通过 declaration merging 添加额外的 `SessionEventMap` 类型。这些是**仅日志**事件：不是 `SurfaceEventType`（不携带 `surfaceOp`，不参与派生历史）。事件所有方决定它们属于一个开放的执行轮次，还是可以独立位于轮次之间，并在自己的不变量配套插件中强制所需关系。完整的逐事件枚举（核心与插件贡献的，含 payload 与溯源信息）见生成的[持久化日志事件目录](../persistence-catalog.md)；压缩 seam 的 `compact/*` 语义在 [compaction.md](compaction.md) 中讨论。

 For pull requests, the gate runs only in the Linux consumer job: these scenarios target POSIX, and the other PR jobs do not provision Chromium. The hosted and self-hosted default-branch Linux serial aggregates also include the comparison, while the macOS and Windows serial jobs remain browser-free. A PR's `all checks passed` verdict already depends on the consumer job, so a browser compare failure blocks the merge without requiring a new branch-protection check name.
 
+An observed self-hosted consumer run measured `web-snapshot` at 112.15 seconds and the full consumer aggregate at 114.97 seconds. The gate scheduler starts it as soon as `built-package-invariants` succeeds and runs independent gates concurrently, so it needs neither a dedicated job timeout nor a manual YAML ordering rule.

 and tighten the docs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`isInheritedSeq` had no production caller — only its own tests — so it was
a public core export shaped by nothing. A bracket owner reads the boundary
positionally; the helper belongs with the compaction seam, where a real
consumer decides its signature.

Also condense the `session/inherited` and `lastActivityTime` docs.

 `Session`'s constructor appends the log-only `session/inherited` event as the seeded session's first live write, at the seq `firstLiveSeq` names. The event is the durable projection of that field: `firstLiveSeq` answers "which prefix did I inherit" for a consumer holding the object, the event answers it for one holding only stored bytes. Its payload is empty — position and `time` carry the whole meaning — and it is not a `SurfaceEventType`, so it produces no message and cannot perturb derived history.
 
-`isInheritedSeq(events, seq)` (exported from `dsh-session`) is the predicate a bracket owner calls on an unmatched opening marker. True means the marker belongs to a lifecycle that has ended and cannot still be running. Core writes the boundary and reads nothing from it; each bracket's vocabulary stays with its owning plugin.
+A bracket owner reads it positionally: an unmatched opening marker below the boundary belongs to a lifecycle that has ended and cannot still be running. Core writes the boundary and reads nothing from it; each bracket's vocabulary stays with its owning plugin, so no core predicate helper ships without a consumer to shape it.
 
-The constructor is the placement because it is the single waist every seeded session passes through. All six entry points reach it: `agents.resume()`, config-driven startup on a persisted id (`restoreOrCreateConfigured`), `sessions.fork()`, a subagent fork child, `coordinator.adopt()`'s live-prefix path, and a bare `sessions.create(id, {seed})`. A boundary written at persistence load would miss both fork paths — and a forked child inheriting a still-running parent's open `compact/start` is precisely the case the predicate must classify. A boundary written at loop start would miss `fork()` and `adopt()`, and would have to fire on `SessionStartSource: 'startup'`, which is what a fork child publishes, so that field would stop discriminating.

 Two guards keep the marker from becoming noise. An empty seed writes nothing: a boundary with nothing below it marks nothing. A seed already ending in one is not re-marked, which makes the write idempotent. Idempotence is load-bearing rather than tidiness — `agentFor()` resumes a cold session on first touch, so merely opening one in a client is a pickup, and without the guard browsing would grow a log by one event per visit.

The persistence packages keep a pure read path. `firstLiveSeq` gains a durable twin rather than a second, competing notion of the same boundary.
 
 Cost: a seeded session's log is one event longer, which moved seq expectations in tests across nine packages (session, agent-loop, persistence contract, jsonl, session-query, session-title, subagent-inprocess, telemetry, token-meter). Two of those updates are load-bearing rather than mechanical: telemetry's adoption tests now assert the boundary IS exported, because it is this lifecycle's own write, and the property suite's replay invariant is restated as "seed reproduced verbatim, plus one log-only boundary" with idempotence added as its own property.
 
 `session/inherited` joins the on-disk vocabulary. Under the pre-release stance (`SESSION_FORMAT_VERSION` pinned at `0`, no compatibility promise) older logs simply lack it, and a log without a boundary correctly reports nothing as inherited.
 
-Not built here: no plugin consumes `isInheritedSeq` yet. Wiring the compaction seam's staleness check to it is the follow-up that motivated this boundary, and it belongs with that seam's own tests.

 A seeded session — resume, fork, or replay — appends this log-only event as its first live write, at the seq its `firstLiveSeq` names. It is the durable projection of that field: `firstLiveSeq` answers "which prefix did I inherit" for a consumer holding the object, this event for one holding only stored bytes. The payload is empty, so position and `time` carry the whole meaning, and it produces no message. An empty seed writes nothing, and a seed already ending in one is not re-marked, so reopening an untouched session does not grow its log per open.
 
-It exists because inherited history and live work are otherwise byte-identical, which defeats any plugin owning a standalone open/close bracket: an unmatched `compact/start` reads the same whether the writer crashed mid-compaction or is compacting right now. `isInheritedSeq(events, seq)` is the predicate a bracket owner calls — true means the opening marker belongs to an ended lifecycle, whatever ended it (a crash, a succeeding process, or a fork out of a still-running parent). It classifies only brackets *this* session inherited: a concurrently live session holding an open bracket over the same history has its own boundary elsewhere, so tolerating concurrent writers needs a liveness signal beyond the log. Core writes the boundary and reads nothing from it — a bracket's vocabulary stays with its owning plugin, which is why crash repair closes turn/step/tool boundaries and never `compact/*`.

An opening marker below the boundary belongs to an ended lifecycle, whatever ended it (a crash, a succeeding process, or a fork out of a still-running parent), so its owner may treat it as dead. That covers only brackets *this* session inherited: a concurrently live session holding an open bracket over the same history has its own boundary elsewhere, so tolerating concurrent writers needs a liveness signal beyond the log. Core writes the boundary and reads nothing from it — a bracket's vocabulary stays with its owning plugin, which is why crash repair closes turn/step/tool boundaries and never `compact/*`.
 
 Activity ordering excludes the boundary through `lastActivityTime(events)`: picking a session up is not work, and lazy resume means browsing writes one, so a resume picker or session list ordering by log tail would float every opened session to the top.

 带种子的会话（恢复、fork 或重放）把这个仅日志事件作为自己的第一次实时写入追加，位置正是 `firstLiveSeq` 指出的 seq。它是该字段的持久投影：`firstLiveSeq` 为持有对象的消费方回答"我继承了哪一段前缀"，这个事件则为只持有存储字节的消费方回答同一问题。payload 为空，因此位置与 `time` 承载全部含义，且不产生任何消息。空种子不写入任何内容；种子本身已以该事件结尾时不会重复标记，因此重新打开一个未被改动的会话不会每次打开都增长日志。

Subject: [PATCH 187/212] fix(session): close the review gaps the boundary
 opened
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- `SessionSummary.updatedAt`'s wire doc still said "Persisted file mtime",
  which stopped being true for attached sessions.
- The core invariant let `session/inherited` fall through the merge-extensible
  default. It is core-owned, so it gets an explicit case; an unbalanced seed
  legally places it inside an open turn, which the relation permits.
- The Agent Note claimed the boundary reaches disk via `live.pending`/
  `scheduleDrain`. Verified false: the constructor append precedes `enter()`,
  so it never publishes on `session/event` and rides the creation seed instead.
  Attaching is therefore a write where none happened before — recorded, since
  only `load()` stays a pure read.
- The deferred-index proposal asserted this change documented the cold-mtime
  skew on `dsh-host-apiproxy`. It did not; the README entry now exists.
- `firstLiveSeq`'s firehose gap runs through its own seq, not below it.
- The boundary is not always at `firstLiveSeq` (the idempotence guard), so
  consumers scan for the last one.
- `lastActivityTime` excludes by type, so a pickup time still leaks onto a
  synthetic closer when a boundary ends an open turn. Documented.
- Pin the fork claim end-to-end: a child inherits a still-running parent's
  open bracket below its own boundary, while the parent has none. Fails if the
  write moves back to the load path.
- Fix the telemetry title that contradicted its own assertions.

The `/status` call site cannot be pinned the way the other two are: the
command appends its own `command/run` before rendering, so the boundary is
never the log tail there. Its fixture now at least renders over a
boundary-bearing log.

 ## Persistence needs no changes
 
-The marker is in `session.events` before the coordinator captures its creation seed, so it persists through the ordinary seed path — `onCreated`'s `createCore` + `appendCore`, or the ownerless-claim suffix write. No load-path write, no revision bump at load, no durable mark on a rejected `append`, and a read-only store still serves loads.
+The constructor append happens before `enter()`, so the session has no store attachment: the marker never publishes on `session/event`, exactly like the seed events below it. It is instead part of the log `initFor` captures as the creation seed, and persists through the ordinary seed path — `onCreated`'s `createCore` + `appendCore`, or the ownerless-claim suffix write. A consumer that watches the firehose therefore never sees the boundary and must read it from the log.
 
-Being a live event, it reaches disk through the write-behind drain (`session/event` → `live.pending` → `scheduleDrain`) rather than a synchronous commit, so a crash can lose it. That costs nothing: `pending` drains in order, so a lost boundary means every live event above it is lost too, and the next pickup reads the same bytes the previous one did, appends its own boundary, and classifies the bracket identically. In-process consumers should prefer `firstLiveSeq`, which is exact before any write.
+Consequences for the seam: `load()` stays a pure read, with no revision bump, no `commitRepair` on a balanced log, and no durable mark left by a rejected `append`. **Attaching is not a pure read**, though — a pickup now writes where nothing was written before, so a read-only or full disk fails at `session/created` rather than at the first real turn. That is the one cost this placement adds, and it is narrower than the load-path version's (which failed the load itself).

-协调器捕获创建种子时该标记已在 `session.events` 中，因此它通过普通的种子路径落盘——`onCreated` 的 `createCore` + `appendCore`，或无主认领的后缀写入。没有加载路径写入、加载时没有 revision 递增、被拒绝的 `append` 不留下持久标记，只读存储依然可以服务加载。
+构造函数中的 append 发生在 `enter()` 之前，因此会话尚无 store attachment：该标记不会在 `session/event` 上发布，与它下方的种子事件完全一样。它属于 `initFor` 捕获的那份创建种子，并通过普通的种子路径落盘——`onCreated` 的 `createCore` + `appendCore`，或无主认领的后缀写入。因此监听 firehose 的消费方永远看不到这条边界，必须从日志中读取它。
 
-作为实时事件，它经由后写式 drain（`session/event` → `live.pending` → `scheduleDrain`）而不是同步提交到达磁盘，因此崩溃可能丢掉它。这没有代价：`pending` 按序 drain，所以丢掉一个边界意味着它上面的每个实时事件也一起丢掉，而下一次接手读到的字节与上一次相同，会追加自己的边界，并对括号作出完全相同的判定。进程内消费方应优先使用 `firstLiveSeq`，它在任何写入之前就是精确的。
+对 seam 的影响：`load()` 仍是纯读取，没有 revision 递增，对平衡日志不走 `commitRepair`，被拒绝的 `append` 也不留下持久标记。但**接手不是纯读取**——如今一次拾起会在此前完全无写入的路径上产生写入，因此只读存储或磁盘写满会在 `session/created` 处报错，而不是在第一个真实轮次处。这是本放置方式新增的唯一成本，并且比加载路径方案的成本更窄（后者会让加载本身失败）。

 The attached projection has a real fix — `lastActivityTime()` skips boundaries — but it needs the event log, and the cold path deliberately does not read one. Reading the log to compute `updatedAt` would defeat the header-only listing that keeps `list()` scaling with session count rather than log size.

 - **Reserved seams stay out of `RpcMethodMap`** — `session.fork`, `prompt.mode: 'inject'`, `task.list`, `host.listModels`, and a describe `hostInstanceId` are documented reservations; an unknown method fails loud at envelope parse rather than getting a not-implemented code.
 - **No protocol version field** — client and host ship together; `host.describe` gains a version negotiation field only when an independently released client exists.
 - **Linux native picker requires desktop tooling** — under the `native` capability, `host.pickDirectory` reports an actionable error when neither Zenity nor KDialog is installed; the browse backend is the composition-level fallback (see the [native backend README](../directory-picker-native/README.md)).
+- **A cold session's `updatedAt` counts a mere pickup as a write (per-file backends only)** — the attached projection excludes the `session/inherited` boundary, because picking a session up is not activity, but a cold session's `updatedAt` is its log file's mtime and every durable write refreshes that, the boundary included. `agentFor()` resumes a cold session on first touch, so merely opening one in a client writes it. This applies only where `locate()` resolves a per-session artifact, i.e. JSONL; SQLite returns `undefined`, so its cold sessions fall back to `createdAt` and are skewed the other way — too old rather than too new — independently of this boundary. A session touched without being worked in therefore sorts newer than its last real activity until it attaches. Separating the two needs a log read, which is exactly what the mtime path exists to avoid; a stored last-activity field in the index would fix it at the source, scoped in the [last-activity-index Agent Note](../../../.agents/notes/proposed/architecture/2026-07-29-durable-last-activity-index.md).

 - **没有协议版本字段**：客户端与宿主一同发布；只有出现独立发布的客户端后，`host.describe` 才会增加版本协商字段。
 - **Linux 原生选择器依赖桌面工具**：在 `native` 能力下，Zenity 和 KDialog 均未安装时，`host.pickDirectory` 会给出包含解决建议的错误提示；组合层面的回退是 browse 后端（见 [native 后端 README](../directory-picker-native/README.md)）。
+- **冷会话的 `updatedAt` 会把一次单纯的拾起算作写入（仅逐文件后端）**：已附加投影排除了 `session/inherited` 边界，因为接手一个会话不算活动；但冷会话的 `updatedAt` 取自其日志文件的 mtime，而每一次持久写入都会刷新它，包括这条边界。`agentFor()` 会在首次触碰时恢复一个冷会话，因此在客户端里仅仅打开一个会话就会写入它。这只适用于 `locate()` 能解析出逐会话产物的场景，即 JSONL；SQLite 返回 `undefined`，因此它的冷会话回退到 `createdAt`，偏差方向相反——偏旧而不是偏新——且与这条边界无关。于是一个被触碰过却没有在里面工作过的会话，在重新附加之前会排在它最后一次真实活动之后。要把两者区分开需要读取日志，而这恰恰是 mtime 路径存在的目的；在索引中存储一个最后活动字段可以从源头修好它，范围见[最后活动索引 Agent Note](../../../.agents/notes/proposed/architecture/2026-07-29-durable-last-activity-index.md)。

+# Agent Note: Web details default closed

+
+## Problem
+
+The transient layout store initialized details to its 360px contract width. The first connected Session and every full reload therefore reserved a right column before the user selected any detail content. Chat tool rows deliberately remain inline and do not open details, while Trajectory rows open the panel when an event is selected, so an open layout default did not represent an active detail selection.
+
+## Decision
+
+The layout store initializes details to zero while retaining the existing 360px contract default for `openDetails()`. `AppFrame` keeps the details slot mounted at zero width, so an explicit entry point such as Trajectory event selection can open the panel without remounting its subtree. The [Session ownership lifecycle](2026-07-29-web-details-session-lifecycle.md) remains authoritative: unselected surfaces derive zero width without taking ownership, returning to the same Session preserves an explicitly opened width, and selecting a different Session closes it.
+
+Panel geometry remains transient. No browser storage key is introduced, and reload restores the sidebar default while details returns to zero. Component tests pin the store default, mounted zero-width slot, drag and concession behavior after explicit opening, and Session ownership transitions. The keyless shipped-composition regression pins the closed first Session, reload, new-session surface, and subsequent Session selections.
+
+## Alternatives considered
+
+**Persist the last open or closed preference.** Rejected because reload should have a deterministic closed baseline, and persisting geometry would reintroduce stale viewing state across browser sessions.
+
+**Keep details open until Chat receives a replacement selection gesture.** Rejected because empty space is not useful detail content. Chat's inline tool-row interaction and any future detail-selection gesture are separate product decisions.
+
+**Remove the details column and layout service.** Rejected because Trajectory already opens event details through this seam, and keeping the mounted slot preserves that working interaction.
+
+## Consequences
+
+New, restored, and reloaded Sessions use the full center area until an explicit details action opens the right column. Trajectory event selection can still open details at 360px and its close control returns the track to zero; Chat tool rows remain geometry-inert. Switching to another Session closes an opened panel, and no panel state survives reload.

+# Agent Note: Web 详情栏默认关闭
+
+Status: implemented
+
+[English](2026-07-30-web-details-default-closed.md) | 中文
+
+## 问题
+
+瞬时布局 store 原本将详情栏初始化为 360px 的契约宽度。因此，首个已连接会话以及每次完整重新加载都会在用户选择任何详情内容之前预留右侧栏。Chat 工具行有意保持内联，不会打开详情栏；Trajectory 行则会在选中事件时打开详情栏。因此，布局默认打开并不表示存在有效的详情选中项。
+
+## 决策
+
+布局 store 将详情栏初始化为零，同时保留 `openDetails()` 现有的 360px 契约默认宽度。`AppFrame` 仍以零宽度挂载详情 slot，因此 Trajectory 事件选择等显式入口可以打开详情栏，而无需重新挂载其子树。[会话所有权生命周期](2026-07-29-web-details-session-lifecycle.md)仍是权威契约：未选中表面会派生零宽度而不取得所有权；返回同一会话时会保留显式打开后的宽度；选择不同会话时则会关闭详情栏。
+
+面板几何信息仍是瞬时状态。系统不新增浏览器存储键；重新加载会恢复侧边栏默认值，并使详情栏回到零宽度。组件测试固定验证 store 默认值、保持挂载的零宽度 slot、显式打开后的拖动与让步行为，以及会话所有权过渡。无密钥的已交付组合回归测试固定验证首个会话保持关闭、重新加载、New Session 表面和后续会话选择。
+
+## 考虑过的替代方案
+
+**持久化最后一次打开或关闭的首选状态。** 之所以否决：重新加载必须具有确定的关闭基线，而持久化几何信息会在浏览器会话之间重新引入陈旧的查看状态。
+
+**在 Chat 获得替代性的选择手势前保持详情栏打开。** 之所以否决：空白区域不是有用的详情内容。Chat 的内联工具行交互与未来可能增加的详情选择手势属于彼此独立的产品决策。
+
+**移除详情栏和布局服务。** 之所以否决：Trajectory 已经通过该服务边界打开事件详情；继续挂载该 slot 可以保留这一正常工作的交互。
+
+## 后果
+
+新建、恢复和重新加载的会话会使用完整的中央区域，直至显式详情操作打开右侧栏。Trajectory 事件选择仍可将详情栏打开至 360px，其关闭控件会使轨道回到零；Chat 工具行仍不改变几何信息。切换到其他会话会关闭已打开的详情栏，并且任何面板状态都不会在重新加载后保留。

 Shell plugin: three-column AppFrame (drag handles and concession chain) plus the `ctx.layout` panel-geometry service; it registers into the runtime-owned `root` slot and declares `sidebar`, `conversation`, `details`, and `conversation.empty`. The sidebar is fixed-width (only details shrinks, then auto-closes); a closed sidebar retains a 56px control rail while details closes to zero width. The package also seats the theme presenter: it consumes resolved `ctx.theme` snapshots and projects them onto the document (`html { color-scheme }` for native UA chrome, `body[data-ds-dark-theme]` from the active color scheme, plus the theme's alias tokens as inline variables on body).
 
-AppFrame always mounts the conversation and details columns; a connected Session renders through `SessionProvider`. The transient layout store starts both panels at their default widths and never reads or writes `localStorage`. Hero and other unselected states derive a zero rendered details width without changing that stored preference. AppFrame retains the last non-blank Session id across those states: the first Session opens at the default width, returning to the same Session restores its unchanged width, and selecting a different Session closes details before paint. The conversation owner share is empty, while the sidebar owner share contains only `collapsed` and `width`; registrants obtain business data from standard hooks and actions from their own inject faces.

 ## Known Limitations and Deferred Work

+- **Panel geometry is transient** — reload restores the sidebar default and details closed; switching between distinct Session ids also closes details and forgets its dragged width, while unselected surfaces render details at zero width without modifying geometry.
 - **Concession-chain auto-close derives a zero width without touching the preferred width** — the panel restores itself when the window widens; consumers must not read the stored details width as the rendered truth.
 - **Scroll anchoring during squeeze reflow is not implemented** — deferred with the virtualized-list project.

Subject: [PATCH 191/212] docs(session): make the boundary's position and
 ownership conditional
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Documentation only; no behavior change.

`firstLiveSeq`'s JSDoc still stated the boundary sits at that seq
unconditionally. Verified reachable on a plain production path: pick up a log,
do no work, pick it up again — the seed already ends in a boundary, so it is
not re-marked and `events[firstLiveSeq]` is undefined. Both that claim and the
firehose-gap sentence are now conditional, with the locate rule ("scan for the
last boundary") matching what types.ts already said.

`repair.ts`'s header claimed this module supplies the boundary. It does not —
the constructor does; this module supplies the activity read that must skip it.
Reworded, and it now names the closer timestamp leak, which is the one real
coupling that justifies `lastActivityTime` living beside the repair synthesis.

Recorded that `Session`'s constructor is the boundary's only legitimate writer,
since the invariant companion constrains nothing and a plugin-side append would
silently turn live brackets below it into dead history.

 ## The inherited-history boundary: `session/inherited`
 
-A seeded session — resume, fork, or replay — appends this log-only event as its first live write, at the seq its `firstLiveSeq` names. It is the durable projection of that field: `firstLiveSeq` answers "which prefix did I inherit" for a consumer holding the object, this event for one holding only stored bytes. The payload is empty, so position and `time` carry the whole meaning, and it produces no message. An empty seed writes nothing, and a seed already ending in one is not re-marked, so reopening an untouched session does not grow its log per open.

+An empty seed writes nothing, and a seed already ending in a boundary is not re-marked, so reopening an untouched session does not grow its log per pickup. Locate the boundary as the log's LAST one rather than at `firstLiveSeq`: after a pickup with no work, the next one leaves it below that seq.
 
 It exists because inherited history and live work are otherwise byte-identical, which defeats any plugin owning a standalone open/close bracket: an unmatched `compact/start` reads the same whether the writer crashed mid-compaction or is compacting right now. An opening marker below the boundary belongs to an ended lifecycle, whatever ended it (a crash, a succeeding process, or a fork out of a still-running parent), so its owner may treat it as dead. That covers only brackets *this* session inherited: a concurrently live session holding an open bracket over the same history has its own boundary elsewhere, so tolerating concurrent writers needs a liveness signal beyond the log. Core writes the boundary and reads nothing from it — a bracket's vocabulary stays with its owning plugin, which is why crash repair closes turn/step/tool boundaries and never `compact/*`.

+空种子不写入任何内容；种子本身已以该边界结尾时不会重复标记，因此重新打开一个未被改动的会话不会每次拾起都增长日志。定位边界应取日志中的**最后一条**，而不是读 `firstLiveSeq`：在一次没有产生工作的拾起之后，下一次拾起会让边界落在该 seq 之下。
 
 它之所以必要，是因为继承历史与实时工作在字节层面完全相同，这会让任何拥有独立开／闭括号的插件失效：一个未配对的 `compact/start`，无论写入方是在压缩中途崩溃、还是此刻正在压缩，读起来都一样。边界之下的开启标记属于一个已结束的生命周期，无论结束原因为何（崩溃、进程接替，或从仍在运行的父会话 fork 出来），因此其所有方可以视之为已死。这只覆盖*本*会话继承的括号：另一个并发存活的会话可能在同一段历史上持有开放括号，而它自己的边界在别处，因此容忍并发写入方还需要日志之外的存活信号。核心写入该边界但不从中读取任何内容——括号的词汇表仍归其所属插件，这也正是崩溃修复只关闭轮次／步骤／工具边界而从不处理 `compact/*` 的原因。

 DeepSeek Harness ships [`@deepseek-ai/dsh-tui`](../../../../packages/ui/tui/README.md) as a dedicated Cordis plugin. It owns terminal input and presentation only; agent lifecycle, session persistence, tool execution, and the model-facing question tool remain separate composition entries. The plugin requires both stdin and stdout to be TTYs and fails instead of silently changing to line-oriented behavior.
 
-There is one terminal front door. `@deepseek-ai/dsh-tui` mounts before the configured agent, and `apps/cli/config/tui.cordis.yml` — an overlay over the shared `base.cordis.yml` — owns the interactive coding composition, with the Code Mode overlay in `examples/code-mode`. Non-interactive tasks use `@deepseek-ai/dsh-cli-demo`; ACP remains a separate automation protocol.
+There is one terminal front door. `@deepseek-ai/dsh-tui` mounts before the configured agent, and `apps/cli/config/tui.cordis.yml` — an overlay over the shared `base.cordis.yml` — owns the interactive coding composition. Non-interactive tasks use the official headless surface; ACP remains a separate automation protocol and owns the supported Code Mode demo.
 
 The selected front door receives the exact generated or resumed `SessionId` used by the pre-created agent. It mounts before the agent composition, waits for the matching root agent, and enters full-screen mode only after that agent exists. A matching `agent-loop/config-start-failed` event is therefore reported before screen takeover and exits with status 1.

 The persisted projection cache ([RFC](2026-07-27-session-projection-and-command-log.md), shipped as `dsh-session-projection-cache`) surfaced two gaps in the storage substrate it landed on. Both are properties of the domain-KV stack ([design](2026-07-24-domain-kv-storage-and-workspace.md)), not of the cache itself, and both bite the cache first because it is the first *derived* medium on that stack.
 
-**Where the files actually live.** The shipped composition gives the json backend a relative root — `root: './.storages'` (apps/cli/cordis.yml) — and `AppCLIEntry.composePatches` patches only the session store's root to the global harness home (`$DSH_HOME/sessions`, default `~/.dsh/sessions`, profile-overridable via `persistenceRoot`); no equivalent patch or profile key exists for `storage-json`. `JsonStorageBackend` never resolves its root either — each unit open joins the still-relative path against whatever `process.cwd()` is at that moment (packages/storage/storage-json/src/index.ts) — the exact hazard the JSONL session backend resolves-once to prevent ("later process.cwd() changes cannot split one backend across roots", packages/session-persistence/session-persistence-jsonl/src/index.ts). Net effect: session logs are global across launch directories, but `workspace.json` and `session_projcache.json` land under `<launch dir>/.storages/`. Two launches from different directories share their sessions yet see different workspace registries and different projection caches — and the cache exists precisely to serve the cross-session cold listing, which now misses for every session last cached under another launch directory.
+**Where the files actually live.** The shipped Web overlay gives the json backend a relative root — `root: './.storages'` (`apps/cli/config/web.cordis.yml`) — while the shared base defaults the session store to the global harness home (`$DSH_HOME/sessions`, default `~/.dsh/sessions`); no equivalent global root exists for `storage-json`. `JsonStorageBackend` never resolves its root either — each unit open joins the still-relative path against whatever `process.cwd()` is at that moment (packages/storage/storage-json/src/index.ts) — the exact hazard the JSONL session backend resolves-once to prevent ("later process.cwd() changes cannot split one backend across roots", packages/session-persistence/session-persistence-jsonl/src/index.ts). Net effect: session logs are global across launch directories, but `workspace.json` and `session_projcache.json` land under `<launch dir>/.storages/`. Two launches from different directories share their sessions yet see different workspace registries and different projection caches — and the cache exists precisely to serve the cross-session cold listing, which now misses for every session last cached under another launch directory.
 
 **How recovery works today.** Inside a healthy medium the cache is fully self-healing by design: a `stateVersion`-mismatched row is discarded and refolded, a log shrunk below a row's watermark is detected by the anchored restore floor and answered with one full re-read, and every background write is fail-soft. But at the *medium* level there is no recovery at all: a truncated, hand-edited, or version-bumped `session_projcache.json` fails `openJsonUnit` with `malformed-medium`/`version-mismatch` (packages/storage/storage-json/src/format.ts), a schema-drifted record fails domain open with `invalid-record` (packages/storage/storage-domain/src/index.ts), the rejection propagates through `SessionProjectionCache[Service.init]`, and under the CLI's fail-loud boot the assembly refuses to start. A file whose entire content is rebuildable from session logs can brick boot. This contradicts the cache package's own stated stance ("a stale or unreadable cache costs a longer tail replay, never a wrong value") and the cache domain spec's JSDoc ("version bumps discard the whole medium"), which today describes an aspiration, not the implementation. The same fail-loud path is *correct* for `workspace.json` — workspace records are authoritative, not derivable — so the missing concept is a per-domain declaration of authority, not a global behavior change.

 持久投影缓存（[RFC](2026-07-27-session-projection-and-command-log.md)，已作为 `dsh-session-projection-cache` 落地）暴露了它所依托的存储基座的两个缺口。二者都是 domain-KV 栈（[设计](2026-07-24-domain-kv-storage-and-workspace.md)）的属性而非缓存自身的问题，且都首先咬到缓存——因为它是这条栈上第一个*派生*介质。
 
-**文件到底存在哪。** 出厂组合给 json 后端的是相对根目录——`root: './.storages'`（apps/cli/cordis.yml）——而 `AppCLIEntry.composePatches` 只把会话存储的根 patch 到全局 harness home（`$DSH_HOME/sessions`，默认 `~/.dsh/sessions`，可经 profile 键 `persistenceRoot` 覆盖）；`storage-json` 没有对应的 patch 也没有 profile 键。`JsonStorageBackend` 自己也从不 resolve 根——每次打开 unit 都把仍然相对的路径 join 到当时的 `process.cwd()` 上（packages/storage/storage-json/src/index.ts）——这正是 JSONL 会话后端用「构造时 resolve 一次」防住的那个隐患（"later process.cwd() changes cannot split one backend across roots"，packages/session-persistence/session-persistence-jsonl/src/index.ts）。净效果：会话日志跨启动目录全局共享，但 `workspace.json` 和 `session_projcache.json` 落在 `<启动目录>/.storages/` 下。从两个不同目录启动，会话相同，工作区注册表和投影缓存却各是一份——而缓存存在的意义恰恰是跨会话冷列表，如今凡是上次在别的启动目录下缓存过的会话全部 miss。
+**文件到底存在哪。** 出厂 Web overlay 给 json 后端的是相对根目录——`root: './.storages'`（`apps/cli/config/web.cordis.yml`）——而共享 base 将会话存储默认为全局 harness home（`$DSH_HOME/sessions`，默认 `~/.dsh/sessions`）；`storage-json` 没有对应的全局根目录。`JsonStorageBackend` 自己也从不 resolve 根——每次打开 unit 都把仍然相对的路径 join 到当时的 `process.cwd()` 上（packages/storage/storage-json/src/index.ts）——这正是 JSONL 会话后端用「构造时 resolve 一次」防住的那个隐患（"later process.cwd() changes cannot split one backend across roots"，packages/session-persistence/session-persistence-jsonl/src/index.ts）。净效果：会话日志跨启动目录全局共享，但 `workspace.json` 和 `session_projcache.json` 落在 `<启动目录>/.storages/` 下。从两个不同目录启动，会话相同，工作区注册表和投影缓存却各是一份——而缓存存在的意义恰恰是跨会话冷列表，如今凡是上次在别的启动目录下缓存过的会话全部 miss。
 
 **现在是怎么恢复的。** 在健康介质内部，缓存按设计完全自愈：`stateVersion` 不匹配的行被丢弃重折，日志缩短到行水位以下由带锚的 restore floor 检出并以一次全量重读回答，每次后台写都是 fail-soft。但在*介质*层面完全没有恢复：被截断、被手改或版本被 bump 的 `session_projcache.json` 会让 `openJsonUnit` 以 `malformed-medium`/`version-mismatch` 失败（packages/storage/storage-json/src/format.ts），schema 漂移的记录让域 open 以 `invalid-record` 失败（packages/storage/storage-domain/src/index.ts），拒绝一路穿过 `SessionProjectionCache[Service.init]`，在 CLI 的 fail-loud 启动下整个组装拒绝启动。一个内容完全可从会话日志重建的文件能把启动搞死。这与缓存包自己声明的立场（"a stale or unreadable cache costs a longer tail replay, never a wrong value"）和缓存域 spec 的 JSDoc（"version bumps discard the whole medium"）相矛盾——后者今天描述的是愿望而非实现。同一条 fail-loud 路径对 `workspace.json` 却是*正确*的——工作区记录是权威数据，不可派生——所以缺的概念是按域声明权威性，而不是全局改行为。

Subject: [PATCH 193/212] test(web): re-record directory-browser golden after
 master merge

The English-locale golden refreshed on master (8c753fd8f1) was recorded
against master's pre-miller dialog; this branch's own golden predated the
miller two-pane landing and was never enforced before the web browser
snapshot CI gate landed. Re-recorded against the merged tree: two-pane
landing plus the show-hidden footer toggle.

Subject: [PATCH 194/212] test(web): refresh question-composer goldens for the
 merged composer

The master-side refresh batch recorded these goldens against master's
composer (customTrigger row, header pager); the merge keeps this
branch's redesigned composer (always-visible custom input, footer
pager) with copy on the standard locale seat, so the waiting aria and
the answered transcript re-record against the merged UI. The answered
golden also picks up the ask_user_question toolview row this branch
introduces.

Subject: [PATCH 195/212] docs(web): the composer bar is one session-maybe
 slot, not a swapped pair
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

fix(web): keep one composer bar DOM across the no-workspace transition

The composer.bar slot moves from session to session-maybe scope: with no
current session the entry still mounts, the machine faces (keyboard, stop,
command) arrive undefined, and the bar renders its normal DOM inert via the
disabled owner prop. DisabledInputBar and its parallel tree are gone, so the
textarea node survives the cold-start workspace pick instead of flashing
through a remount. A blank session whose workspace was deleted takes the
same inert path through owner props.

test(web): add the composer DOM-continuity acceptance probe

Drives a real dsh web server with headless chromium through the cold-start
-> pick-workspace -> type flow and asserts the composer textarea is the
same DOM node throughout (a marker property must survive). Rerun
prerequisites are in the header comment.

docs(web): session-maybe identity is adoption, not hold-forever

fix(web): session-maybe entries adopt the first session, then remount like strict entries

A session-maybe entry used to keep one React instance across every
transition, so component-local state leaked between sessions once the
composer bar moved to that scope (PermissionSelect's optimistic pick, the
IME composition guard). Identity is now adoption: an incarnation born
session-less holds through the arrival of the first session (the blank
shell's DOM survives the workspace pick), and afterwards behaves exactly
like a strict session entry — a switch or a drop to no-session remounts,
clearing local state by construction. The child key is an incarnation
counter kept in the stable outlet wrapper via render-phase setState.

chore: knip knows the root acceptance probe's playwright dependency

scripts/hero-composer-dom-continuity.mjs resolves playwright through
apps/web's devDependency tree (createRequire), which knip cannot follow;
ignore it at the root workspace.

+- `session-maybe` follows the current session with ADOPTION identity (the only behavior — there is no hold-identity-forever mode): an incarnation born session-less keeps its React instance across the arrival of the FIRST session (the blank shell adopts it — no remount, the DOM survives), and from then on behaves exactly like a strict session entry — switching to a different session remounts, and dropping back to no-session remounts into a fresh blank incarnation that will adopt again. Component-local per-session state therefore clears by construction; state that must survive a switch belongs in session-bound sources (machine, store, hooks). With no session, `sessionId`, the results of `useSession`/`useInput`, and `inputActions` may all be absent.

 - `session` guarantees that `sessionId`, every hook source, and every prop exist; each strict entry's error boundary is keyed by `sessionId`, so switching sessions recreates that entry and its session store.

With no session, the composer stack places the presentation-only `DisabledInputBar` directly; once a session appears, the input body is swapped for the strictly bound InputBar; the textarea may be rebuilt, while the Hero and the layout skeleton are not. The blank → engaging/active transition stays inside the same strict-session subtree, and the InputBar is never rebuilt on a phase flip.

@@ -70,7 +70,7 @@ A trigger/menu/pick pipeline with zero knowledge of "commands":
 
 - The hub (trigger/decoration registries + send orchestration) takes the slash/command services as optional `ctx.get()` dependencies: without ui-slash or the command surfaces, input still sends and receives normally — graceful degradation.
 - Each materialized Session has exactly one `SessionInputShell` (the facade), created and torn down with the session scope; with no session, no input machine is built. `ConversationRoot` is itself the `session-maybe` resident shell, holding HeroShell, the Workspace picker, the composer stack, and the chain-fallback frame.
-- With no session the shell renders the presentation-only `DisabledInputBar`; once `connectWorkspace` returns a blank session, only the input body is swapped for the strict-session InputBar. The textarea may be rebuilt here, while `ConversationRoot`, the Hero, and the layout skeleton hold; blank → engaging/active stays the same session-bound InputBar, with the textarea never rebuilt on a phase flip.
+- The composer bar is one `session-maybe` slot entry rendered unconditionally: with no session the same InputBar renders inert (machine faces absent, `disabled` owner prop), and once `connectWorkspace` returns a blank session the same instance goes live — the textarea DOM survives the no-session → blank transition and every later phase flip; `ConversationRoot`, the Hero, and the layout skeleton hold throughout.
 - ConversationRoot's Hero criterion is `sessionId === undefined || (composerPhase === 'blank' && (openState === 'open' || openState === 'loading'))`. The first submit enters engaging synchronously, and a failure keeps the composer and the error context rather than falling back to the blank Hero; the sidebar's blank bit flips false only after a prompt is successfully accepted.
 - Sending unifies in the hub defaultSink: after an optimistic draft clear it goes only through `session.prompt {mode:'queue'|'steer'}`; backfill happens only when it fails and the live draft is still empty — a user who has kept typing is never overwritten. No Draft materialize or attach transaction exists.
 - When the blank Hero re-picks the Workspace, the shell calls `connectWorkspace`; if the target session differs, the non-empty draft moves from the current shell to the target shell before the new id is opened, and the old blank session survives but is no longer current.

 - hub（trigger/decoration 注册表 + 发送编排）对 slash/command 服务是可选 `ctx.get()` 依赖：无 ui-slash/命令面时输入正常收发，优雅降级。
 - 每个实体 Session 只有一个 `SessionInputShell`（facade），随 session scope 创建和拆除；无 session 时不造 input machine。`ConversationRoot` 自身是 `session-maybe` 常驻外壳，持有 HeroShell、Workspace picker、composer stack 与 chain fallback 外框。
-- 无 session 时外壳渲染纯展示的 `DisabledInputBar`；`connectWorkspace` 返回 blank session 后，仅输入体换成严格 session 的 InputBar。这里允许 textarea 重建，`ConversationRoot`、Hero 与布局骨架保持；blank → engaging/active 仍是同一 session-bound InputBar，textarea 不因 phase 翻转而重建。
+- composer bar 是一个无条件渲染的 `session-maybe` slot entry：无 session 时同一个 InputBar 以惰性态渲染（machine face 缺席、`disabled` owner prop），`connectWorkspace` 返回 blank session 后同一实例转为 live——textarea DOM 在无 session → blank 切换及其后每次 phase 翻转中都不重建；`ConversationRoot`、Hero 与布局骨架全程保持。
 - ConversationRoot 的 Hero 判据是 `sessionId === undefined || (composerPhase === 'blank' && (openState === 'open' || openState === 'loading'))`。首次 submit 同步进入 engaging，失败也保留 composer 与错误上下文，不退回 blank Hero；sidebar 的 blank 位只在 prompt 成功受理后翻 false。
 - 发送统一在 hub defaultSink：乐观清稿后只走 `session.prompt {mode:'queue'|'steer'}`；失败且 live draft 仍为空才回填，用户已经继续输入则不覆盖。不存在 Draft materialize 或 attach 事务。
 - blank Hero 改选 Workspace 时，外壳调用 `connectWorkspace`；目标 session 不同时把非空 draft 从当前 shell 搬到目标 shell，再 open 新 id，旧 blank session 留存但不再 current。

 Per-session UI state for selection and the active view lives in the declared chat store (`stores.ts` `createChatStore`); the InputHub owns the composer state machine and mirrors its draft into that store for persistence. Apply passes one store handle to the strict session subtree, chat view, and details registrations, so each session shares one instance and the framework owns its lifecycle. Components are pure: the framework standard kit supplies `useSession`/`sessionId`, global `useSessions`/`useWorkspaces`, and the input machine's `useInput`/`inputActions`; store faces and inject factories supply the remaining state and callbacks.
 
-The composer bar declares session-scoped single seats for `'conversation.input.plan'` (right of the local access-mode control) and `'conversation.input.model'` (immediately before the pending indicator and send/stop button), plus list slots for overlay, dock, left, and right input extensions. Feature packages own each control and its state; ui-conversation supplies placement, the `locked` owner prop, and the standard slot shares. While the `plan` projection's effective target is plan mode, InputBar swaps its textarea placeholder to the plan-task wording, localized through the `command.hint` locale namespace this package registers and shared verbatim with the claimed `/plan` command hint (a host-folded value read through the standard-kit `useProjection`; owner-supplied placeholders win). A pending composer takeover remains mounted when another conversation view is active so the blocked agent can still receive its answer; without a pending interaction, the active-session composer belongs to Chat. The resident no-session shell uses `DisabledInputBar` and therefore dispatches no session-scoped control seats.

 `src/client/` is organized for the future package split: `contract/` is the sole inter-domain shared face (`slots.ts` slot declarations + composed slot props including the tool-row contract, `views.ts` shared primitives, `tool-call-model.ts`); the `skeleton/`, `chat/`, and `toolviews/` (sample registrants) domain directories import contract files and never each other; `apply.ts` is the only assembly point allowed to import all three domains. The `/client` export surface is the contract only — `apply`/`inject`, the two service classes, and the `contract/` type families; implementation components (skeleton, chat rows) and the store factory stay internal and reach the page exclusively through apply's slot registrations (tests take them via the `./src/*` subpath).

-`Session`'s constructor appends the log-only `session/inherited` event as the seeded session's first live write, at the seq `firstLiveSeq` names. The event is the durable projection of that field: `firstLiveSeq` answers "which prefix did I inherit" for a consumer holding the object, the event answers it for one holding only stored bytes. Its payload is empty — position and `time` carry the whole meaning — and it is not a `SurfaceEventType`, so it produces no message and cannot perturb derived history.
+`Session`'s constructor appends the log-only `session/end-seed` event immediately after a non-empty constructor seed, as the seeded session's first live write at the seq `firstLiveSeq` names. The event is the durable projection of that field: `firstLiveSeq` answers where this lifecycle's writes start for a consumer holding the object, while `session/end-seed` answers the same question for one holding only stored bytes. Its payload is empty — position and `time` carry the whole meaning — and it is not a `SurfaceEventType`, so it produces no message and cannot perturb derived history.
 
-A bracket owner reads it positionally: an unmatched opening marker below the boundary belongs to a lifecycle that has ended and cannot still be running. Core writes the boundary and reads nothing from it; each bracket's vocabulary stays with its owning plugin, so no core predicate helper ships without a consumer to shape it.
+A bracket owner reads it positionally: an unmatched opening marker before `session/end-seed` has a smaller seq, came from the constructor seed, and belongs to a lifecycle that has ended. Core writes the boundary and reads nothing from it; each bracket's vocabulary stays with its owning plugin, so no core predicate helper ships without a consumer to shape it.
 
 The constructor is the placement because it is the single waist every seeded session passes through. All six entry points reach it: `agents.resume()`, config-driven startup on a persisted id (`restoreOrCreateConfigured`), `sessions.fork()`, a subagent fork child, `coordinator.adopt()`'s live-prefix path, and a bare `sessions.create(id, {seed})`. A boundary written at persistence load would miss both fork paths — and a forked child inheriting a still-running parent's open `compact/start` is precisely the case that must be classifiable. A boundary written at loop start would miss `fork()` and `adopt()`, and would have to fire on `SessionStartSource: 'startup'`, which is what a fork child publishes, so that field would stop discriminating.
 
-Two guards keep the marker from becoming noise. An empty seed writes nothing: a boundary with nothing below it marks nothing. A seed already ending in one is not re-marked, which makes the write idempotent. Idempotence is load-bearing rather than tidiness — `agentFor()` resumes a cold session on first touch, so merely opening one in a client is a pickup, and without the guard browsing would grow a log by one event per visit.

 ## Persistence needs no changes
 
-The constructor append happens before `enter()`, so the session has no store attachment: the marker never publishes on `session/event`, exactly like the seed events below it. It is instead part of the log `initFor` captures as the creation seed, and persists through the ordinary seed path — `onCreated`'s `createCore` + `appendCore`, or the ownerless-claim suffix write. A consumer that watches the firehose therefore never sees the boundary and must read it from the log.

 Consequences for the seam: `load()` stays a pure read, with no revision bump, no `commitRepair` on a balanced log, and no durable mark left by a rejected `append`. **Attaching is not a pure read**, though — a pickup now writes where nothing was written before, so a read-only or full disk fails at `session/created` rather than at the first real turn. That is the one cost this placement adds, and it is narrower than the load-path version's (which failed the load itself).
 
-A crash before the seed write reaches disk loses the boundary, and that costs nothing: the pending batch is written in order, so a lost boundary means every event above it is lost too. The next pickup reads the same bytes the previous one did, appends its own boundary, and classifies the bracket identically. In-process consumers should prefer `firstLiveSeq`, which is exact before any write.

 Cost: a seeded session's log is one event longer, which moved seq expectations in tests across nine packages (session, agent-loop, persistence contract, jsonl, session-query, session-title, subagent-inprocess, telemetry, token-meter). Two of those updates are load-bearing rather than mechanical: telemetry's adoption tests now assert the boundary IS exported, because it is this lifecycle's own write, and the property suite's replay invariant is restated as "seed reproduced verbatim, plus one log-only boundary" with idempotence added as its own property.

 选择构造函数，是因为它是每一个带种子会话都必经的唯一收窄处。全部六个入口都会到达它：`agents.resume()`、在已持久化 id 上的配置驱动启动（`restoreOrCreateConfigured`）、`sessions.fork()`、子代理 fork 子会话、`coordinator.adopt()` 的实时前缀路径，以及裸的 `sessions.create(id, {seed})`。在持久化加载时写入的边界会漏掉两条 fork 路径——而一个继承了仍在运行的父会话开放 `compact/start` 的 fork 子会话，恰恰是必须可判定的场景。在 loop 启动时写入的边界会漏掉 `fork()` 与 `adopt()`，并且不得不在 `SessionStartSource: 'startup'` 上触发——那正是 fork 子会话发布的取值，于是该字段将不再具有区分力。
 
-两条守卫让这个标记不至于变成噪声。空种子不写入任何内容：下方什么都没有的边界标记不了任何东西。种子本身已以该事件结尾时不会重复标记，这让写入具备幂等性。幂等性是承重的，而不是为了整洁——`agentFor()` 会在首次触碰时恢复一个冷会话，因此在客户端里仅仅打开一个会话就是一次接手；没有这条守卫，浏览会让日志每访问一次就增长一个事件。

-构造函数中的 append 发生在 `enter()` 之前，因此会话尚无 store attachment：该标记不会在 `session/event` 上发布，与它下方的种子事件完全一样。它属于 `initFor` 捕获的那份创建种子，并通过普通的种子路径落盘——`onCreated` 的 `createCore` + `appendCore`，或无主认领的后缀写入。因此监听 firehose 的消费方永远看不到这条边界，必须从日志中读取它。

 对 seam 的影响：`load()` 仍是纯读取，没有 revision 递增，对平衡日志不走 `commitRepair`，被拒绝的 `append` 也不留下持久标记。但**接手不是纯读取**——如今一次拾起会在此前完全无写入的路径上产生写入，因此只读存储或磁盘写满会在 `session/created` 处报错，而不是在第一个真实轮次处。这是本放置方式新增的唯一成本，并且比加载路径方案的成本更窄（后者会让加载本身失败）。
 
-若崩溃发生在种子写入到达磁盘之前，边界会丢失，而这没有代价：待处理批次按序写入，所以丢掉一个边界意味着它上面的每个事件也一起丢掉。下一次接手读到的字节与上一次相同，会追加自己的边界，并对括号作出完全相同的判定。进程内消费方应优先使用 `firstLiveSeq`，它在任何写入之前就是精确的。

 A cold (persisted, unattached) session has no stored answer to "when was this last worked in". `dsh-host-apiproxy`'s `summarizeCold()` therefore approximates it with the log file's mtime where one exists — `locate()` resolves a per-session artifact for JSONL and `undefined` for SQLite, whose cold sessions fall back to `createdAt` — and the web client sorts its session tree by the resulting `updatedAt`. The two backends are wrong in opposite directions: JSONL reads too new, SQLite too old.
 
-mtime answers a different question: when the artifact was last written. Every durable write refreshes it, including writes that are not activity — a truncate-repair of a torn tail, the synthetic closers that balance an interrupted turn, and the [`session/inherited` boundary](../../implemented/architecture/2026-07-30-session-inherited-log-boundary.md) a seeded session appends. (A `flush` with nothing pending is not among them: the coordinator returns without reaching the backend.) The visible consequence is stable and wrong in one direction: a session touched without being worked in promotes itself above sessions the user actually worked in afterwards, and each touch re-promotes it. "Touched" is broader than "resumed" — `dsh-host-apiproxy`'s `agentFor()` resumes a cold session on first touch, and `sessions.history` reaches it when the web client merely opens one, so ordinary browsing is enough.

 The attached projection has a real fix — `lastActivityTime()` skips boundaries — but it needs the event log, and the cold path deliberately does not read one. Reading the log to compute `updatedAt` would defeat the header-only listing that keeps `list()` scaling with session count rather than log size.

 一个冷会话（已持久化、未附加）对「上次是什么时候在这里面工作过」没有任何已存储的答案。因此 `dsh-host-apiproxy` 的 `summarizeCold()` 在存在日志文件时用它的 mtime 来近似它——`locate()` 为 JSONL 解析出一个逐会话产物，为 SQLite 解析出 `undefined`，而 SQLite 的冷会话会回退到 `createdAt`——而 web 客户端就按由此得到的 `updatedAt` 为自己的会话树排序。这两个后端错的方向正好相反：JSONL 读出来偏新，SQLite 偏旧。
 
-mtime 回答的是另一个问题：这份产物上次是什么时候被写入的。每一次持久写入都会刷新它，包括那些并不是活动的写入：一次对撕裂尾部的截断修复、用来平衡被中断的轮次的那些合成 closer，以及带种子的会话会追加的 [`session/inherited` 边界](../../implemented/architecture/2026-07-30-session-inherited-log-boundary.md)。（没有待处理内容的 `flush` 不在其中：协调器在到达后端之前就返回了。）用户可见的后果是稳定的，而且只朝一个方向错：一个被触碰过却没有在里面工作过的会话，会把自己排到用户此后真正工作过的那些会话之前，而且每次触碰都会重新把它排上去一次。「触碰」比「恢复」的范围更宽——`dsh-host-apiproxy` 的 `agentFor()` 会在首次触碰时恢复一个冷会话，而 web 客户端仅仅打开一个会话时 `sessions.history` 就会到达它，因此普通的浏览就够了。

-空种子不写入任何内容；种子本身已以该边界结尾时不会重复标记，因此重新打开一个未被改动的会话不会每次拾起都增长日志。定位边界应取日志中的**最后一条**，而不是读 `firstLiveSeq`：在一次没有产生工作的拾起之后，下一次拾起会让边界落在该 seq 之下。

-它之所以必要，是因为继承历史与实时工作在字节层面完全相同，这会让任何拥有独立开／闭括号的插件失效：一个未配对的 `compact/start`，无论写入方是在压缩中途崩溃、还是此刻正在压缩，读起来都一样。边界之下的开启标记属于一个已结束的生命周期，无论结束原因为何（崩溃、进程接替，或从仍在运行的父会话 fork 出来），因此其所有方可以视之为已死。这只覆盖*本*会话继承的括号：另一个并发存活的会话可能在同一段历史上持有开放括号，而它自己的边界在别处，因此容忍并发写入方还需要日志之外的存活信号。核心写入该边界但不从中读取任何内容——括号的词汇表仍归其所属插件，这也正是崩溃修复只关闭轮次／步骤／工具边界而从不处理 `compact/*` 的原因。

 - **Reserved seams stay out of `RpcMethodMap`** — `session.fork`, `prompt.mode: 'inject'`, `task.list`, `host.listModels`, and a describe `hostInstanceId` are documented reservations; an unknown method fails loud at envelope parse rather than getting a not-implemented code.
 - **No protocol version field** — client and host ship together; `host.describe` gains a version negotiation field only when an independently released client exists.

This applies only where `locate()` resolves a per-session artifact, i.e. JSONL; SQLite returns `undefined`, so its cold sessions fall back to `createdAt` and are skewed the other way — too old rather than too new — independently of this boundary. A session touched without being worked in therefore sorts newer than its last real activity until it attaches.

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

ui-question no longer listens to locale/change directly — copy rides the
framework locale seat since the standard-seat merge — so the generated
matrix row drops it. gen-doc-graphs output, verified with --check.

Subject: [PATCH 208/212] fix(example): drop the never-activated bash stack
 from the inheritance fixture

dsh-bash-local injects `subprocess`, which this tree never mounted, so the bash
chain sat PENDING and the bundle's tool-bash waited with it. The shared boot()
all-ACTIVE assertion now surfaces that as a load failure.

The scenario probes filesystem confinement only, so the rows are removed and the
bundle opts out with `toolBash: false`. The recorded transcript is unchanged
because bash never reached the model.

Subject: [PATCH 209/212] test(web): anchor the group section above the
 HoverCard wrapper

The workspace header row is now wrapped by its HoverCard anchor span
(0b4a6196f), so the row's immediate parent no longer holds the session
subtree; the delete scenario anchors on the groupSection ancestor
instead. The flat-view and dwell failures were downstream of this one
(shared page state).

+# Agent Note: Composer context stack order
+
+Status: implemented
+

+
+## Problem
+
+Goal, Todo, and Queue contribute independently to the same `conversation.input.dock` list, but their registration order and spacing rules did not encode the composition matrix. The renderer therefore placed Todo before Queue and Goal, while both Queue and Goal carried negative margins intended for the composer boundary. When all three were present, Queue joined to Goal and Goal joined to the composer, reversing the design's hierarchy.
+
+## Decision
+
+The composer context stack has one canonical ascending order: Goal at `0`, Todo at `10`, and Queue at `20`, followed by the composer bar outside the list. The gaps leave room for future entries to declare their intended position without relying on plugin activation order.
+
+`ConversationRoot` owns the 6px space between independent context cards. Goal is a standalone 752×36px card and collapsed Todo is a standalone 752×44px card. Queue is the terminal dock entry: its 776px wrapper contains the same 752px panel column and subtracts the shared gap plus a named 5px layout overlap, so the later composer card paints over only the queue edge. Empty entries render null and consume no gap.
+
+The order and overlap are separate contracts. Registration order establishes semantic hierarchy; CSS variables on the stack establish shared geometry. Queue does not infer that it may overlap merely from being the last visible entry, because Goal or Todo can be the last visible context card when no queue exists and must remain separated from the composer.
+
+## Verification
+
+Registration tests pin all three order values. Browser screenshots cover the full Goal/Todo/Queue matrix, Goal+Todo without Queue, and Queue alone; together they exercise every adjacency: Goal–Todo, Todo–Queue, and Queue–Composer.
+
+## Alternatives considered
+
+**Keep independent negative margins on Goal and Queue.** Rejected because the affected neighbor changes with slot order; a local margin cannot express which relationship is allowed unless the semantic order is also fixed.
+
+**Render each known dock id separately in `ConversationRoot`.** Rejected because it turns an extensible list slot into a hardcoded component inventory and forces the owner to change for every new registrant.
+
+**Tuck whichever dock entry is last.** Rejected because Goal and Todo are standalone cards. Their absence matrix must not change the surface semantics of whichever card remains.
+
+## Consequences
+
+The visual hierarchy is stable for every presence combination, and Queue is the only context surface joined to the composer. New input-dock plugins must choose an order relative to Goal `0`, Todo `10`, and Queue `20`; an entry after Queue also requires an explicit decision about which surface owns the composer boundary.

+# Agent Note: Composer 上下文堆栈顺序
+
+Status: implemented
+
+[English](2026-07-30-composer-context-stack-order.md) | 中文
+
+## 问题
+
+Goal、Todo 与 Queue 独立注册到同一个 `conversation.input.dock` 列表，但各自的注册顺序与间距规则没有编码组合矩阵。因此，渲染器将 Todo 放在 Queue 和 Goal 之前，而 Queue 与 Goal 都带有用于 composer 边界的负外边距。三者同时出现时，Queue 与 Goal 相接，Goal 与 composer 相接，颠倒了设计层级。
+
+## 决策
+
+composer 上下文堆栈采用唯一规范的升序排列：Goal 为 `0`，Todo 为 `10`，Queue 为 `20`，随后是位于列表外的 composer bar。顺序值之间的空档使未来条目可以声明预期位置，不必依赖插件激活顺序。
+
+`ConversationRoot` 负责独立上下文卡片之间的 6px 间距。Goal 是一张独立的 752×36px 卡片，折叠后的 Todo 是一张独立的 752×44px 卡片。Queue 是末端 dock 条目：其 776px 包装层包含相同的 752px 面板列，并减去共享间距与具名的 5px 布局重叠量，因此后渲染的 composer 卡片只覆盖 Queue 边缘。空条目渲染为 null，不占用间距。
+
+顺序与重叠是两项独立契约。注册顺序定义语义层级，stack 上的 CSS 变量定义共享几何。系统不能仅因 Queue 是最后一个可见条目，就推断它可以与 composer 重叠，因为没有 Queue 时，Goal 或 Todo 可能成为最后一个可见上下文卡片，而它们必须与 composer 保持间隔。
+
+## 验证
+
+注册测试固定了三个顺序值。浏览器截图覆盖完整的 Goal／Todo／Queue 组合矩阵、没有 Queue 的 Goal+Todo，以及仅有 Queue 的情况；这些场景共同覆盖全部相邻关系：Goal–Todo、Todo–Queue 与 Queue–Composer。
+
+## 考虑过的替代方案
+
+**Goal 和 Queue 分别保留独立的负外边距。** 不予采纳，因为受影响的相邻项会随 slot 顺序变化；除非语义顺序也固定，否则局部外边距无法表达允许哪一种关系。
+
+**在 `ConversationRoot` 中分别渲染每个已知 dock id。** 不予采纳，因为这会把可扩展的列表 slot 变成硬编码的组件清单，并迫使 owner 在每新增一个注册方时随之修改。
+
+**让最后一个 dock 条目贴卡。** 不予采纳，因为 Goal 和 Todo 是独立卡片；Goal 或 Todo 缺席时的组合不得改变剩余卡片的界面语义。
+
+## 后果
+
+所有存在组合下的视觉层级都保持稳定，Queue 是唯一与 composer 相接的上下文界面。新的 input-dock 插件必须相对于 Goal `0`、Todo `10` 与 Queue `20` 选择顺序；若条目位于 Queue 之后，还必须明确决定由哪个界面负责 composer 边界。

 ## Problem

The mock keeps only a sparkle, a phase word ("Ongoing/Paused/Blocked Goal"), the truncated objective, and edit/clear icon actions, with resume appearing only on a paused goal.
 
 ## Decision
 
-`GoalBar` (`packages/client/ui-goal/src/client/GoalBar.tsx`) is a new props-driven, self-contained component; `ConversationRoot` mounts it immediately before the composer `InputBar`. The strip's CSS mirrors the composer's horizontal geometry (32px side padding, 776px centered cap) plus the mock's 12px inset, and a -10px bottom margin eats InputBar's 8px top padding and tucks its square bottom edge 2px under the composer card's top edge. All strip states share one fixed 38px height so switching between them never resizes it. Loading (`goal === undefined`), absent (`goal === null`), and `phase === 'complete'` render nothing — a completed goal is history, not chrome.
+`GoalBar` (`packages/client/ui-goal/src/client/GoalBar.tsx`) is a props-driven, self-contained component registered first in the composer's input-dock list. Its standalone 752px card follows the composer's horizontal geometry, and every visible state shares one fixed 36px height so switching phases never resizes it. Loading (`goal === undefined`), absent (`goal === null`), and `phase === 'complete'` render nothing — a completed goal is history, not chrome.
 
 Visibility drives the label and actions: active shows "Ongoing Goal" with pause/edit/clear; paused shows "Paused Goal" and swaps pause for a resume icon button; blocked shows "Blocked Goal" and carries `blockedReason.message` as the strip's `title` tooltip. Goal creation lives on the `/goal` command, not in the bar. The pencil swaps the strip for an inline edit form prefilled with the current objective: Enter or the check button saves through `GoalBarActions.onEdit(objective)`, Esc cancels, and an all-whitespace objective keeps save disabled. The form closes only when the edit succeeds; a failure preserves the draft and displays the error in the bar. Resume and clear failures are displayed there as well. Clear otherwise calls `onClear` directly with no confirmation — a clear keeps a durable tombstone, so nothing is unrecoverable. An effect keyed on the goal's id drops the edit form when the goal's identity changes, so a surviving draft can never be written over the goal that replaced it.

 可见性决定标签和操作：active 状态显示 "Ongoing Goal" 并提供暂停／编辑／清除；paused 状态显示 "Paused Goal"，把暂停换成一个恢复图标按钮；blocked 状态显示 "Blocked Goal"，并把 `blockedReason.message` 作为横条的 `title` 悬浮提示。创建目标的入口在 `/goal` 命令上，不在横条里。铅笔图标把横条切换为内联编辑表单，预填当前目标内容：Enter 或勾选按钮通过 `GoalBarActions.onEdit(objective)` 保存，Esc 取消，目标内容全为空白字符时保存按钮保持禁用。编辑成功后表单才会关闭；编辑失败时保留草稿，并在横条中显示错误。恢复和清除失败也显示在横条中。除此之外，清除直接调用 `onClear`，不做确认——清除会保留 durable 墓碑，没有不可恢复的损失。一个以目标 id 为键的 effect 会在目标身份变化时丢弃编辑表单，因此存留的草稿绝不可能覆盖掉替换它的新目标。

 - `'conversation.composer.dock'` entries reach the page as the `ComposerBarOwnerProps.footer` slot, rendered under the card inside the bar's `.root`, so the stats line and the card share one width constraint. `StatsLine` derives everything client-side from the snapshot: turns/steps, LLM wall time from assistant `timing` (`completedTime - stepStartTime`), tool wall time from tool-result `time - callTime` pairs, prompt/output token split with cache-read folded into input, and cache-hit percentage. Groups render pipe-separated and drop out whole when empty; `formatTokens` (517 / 12.2K / 1.2M) and `formatDuration` (45.2s / 2m42s) are exported for tests. Durations cover only in-window nodes — the README owns that limitation.
-- `.composerStack` carries `gap: 8px` and entries carry no outer margins (QueueDock's margin removed), so a dock entry that renders null costs nothing. GoalBar is the one deliberate exception: `margin: 0 auto -10px` cancels the gap and tucks its square bottom edge 2px under the card.
+- `.composerStack` carries the Figma composition matrix's 6px gap. Goal and Todo remain standalone cards; the terminal Queue entry subtracts that gap plus the named 5px layout overlap so the later composer card paints over only the queue edge. The [composer context stack decision](../bug-fix/2026-07-30-composer-context-stack-order.md) owns the order and overlap contract.
 - The sticky seat's background is a `linear-gradient` from `color-mix(bg-base 0%, transparent)` at 0px to solid `bg-base` at 36px — pixel stops, not the figma export's percentage, so a growing draft widens only the solid region; `color-mix` keeps both themes fading from their own base.
 - A `useCallback` ref on the seat attaches a ResizeObserver that publishes `--dsh-composer-height` on the scroll body; ChatView's back-to-bottom slot computes `bottom` from it (152px first-paint fallback) instead of the prior hardcoded 168px.
-- The textarea's 52px two-line floor applies to the hero variant only; the docked composer collapses to content height. Goal and todo strips both use the 44px-gutter / 752px-cap column with the todo `tip` fill and l1 border; the todo header is compacted (13/20 type, 8+8 padding) so its collapsed height equals the goal strip's 38px.
+- The textarea's 52px two-line floor applies to the hero variant only; the docked composer collapses to content height. Goal, Todo, and Queue panels use the 44px-gutter / 752px-cap column with `tip` fill and l1 border; the standalone Goal and collapsed Todo cards are 36px and 44px tall.
 
 ## Alternatives considered
 
 **Percentage gradient stops (the figma export's 24%).** Rejected: the stop scales with seat height, so a tall draft stretches the fade band over most of the transcript; the fixed 36px band equals the design's 24% at the resting ~150px composer and stays constant as the composer grows.
 
-**A skeleton-owned dock column with a generic "bottommost entry tucks" contract.** Built and backed out in review: a `.inputDock` wrapper owning width/rhythm plus `--dsh-dock-tuck-*` vars on `:last-child` would retarget the tuck automatically on reorder, but it rewrote every entry and the GoalBar DOM ahead of a pending merge. Per-entry CSS with GoalBar owning its own tuck was chosen; the generic column remains available if dock entries multiply.
+**A generic "bottommost entry tucks" contract.** Rejected because Goal and Todo are independent cards even when either is the last visible dock entry. Queue owns the one intentional composer overlap, while the stack owns its shared gap and overlap values.

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: '<tool>', 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 (`<done>/<total> 已完成 · <active item>` parsed from its args, falling back to the generic summary on malformed or wrongly-shaped model JSON, and keeping the generic dot for non-ok execution states so a cancelled call never reads as a completed update). `TodoDock` takes the `'conversation.input.dock'` list slot at `order: -1` — above the queue rows — and is the plan strip: it reads the host-computed `todos` projection via `useProjection` (standing plan: latest `todo/write` with no later `turn/start`) and renders `TodoPanel`, which takes the plain list, hides itself while the list is empty, and starts collapsed as a header of title plus `"<done>/<total> tasks · <n> 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.

Anything the input-zone composer chain hides (a `conversation.composer` takeover such as ui-question's) hides the whole dock, this strip included.
 
 Per-session UI state for selection and the active view lives in the declared chat store (`stores.ts` `createChatStore`); the InputHub owns the composer state machine and mirrors its draft into that store for persistence. Apply passes one store handle to the strict session subtree, chat view, and details registrations, so each session shares one instance and the framework owns its lifecycle. Components are pure: the framework standard kit supplies `useSession`/`sessionId`, global `useSessions`/`useWorkspaces`, and the input machine's `useInput`/`inputActions`; store faces and inject factories supply the remaining state and callbacks.

-Goal surface plugin, browser half: the `GoalBar` strip in the `conversation.input.dock` list (order 1, tucked against the composer). The live goal arrives through `useProjection('goal')` — the host-computed whole value seeded by the history tail page and updated by `session/projection` frames — so the plugin owns no store, no refresh chain, and no event listener. The slot inject face carries only the four mutation verbs (edit / pause / resume / clear over the `goal.*` wire domain — an active goal offers the pause action, a paused one resume); each reads the CAS ref from the session's current projected value at call time and surfaces the settled RPC error inline (the RPC's compare-and-set is the staleness guard — there is no client fence). Goal creation stays on the `/goal` host command; loading, absent, and completed goals render nothing.
