+> The Node-native launch vector is superseded by [dsh source launch through the tsx ESM hook](2026-07-29-dsh-source-launch-tsx-esm.md): Node 26.0.0 removed `--experimental-transform-types`, and the paths loader described here is deleted. The Cordis-config declaration gate (`verify-cordis-config`), the app-boot fail-loud plugin diagnostic, and the vendored `import type` marks remain current.
+
 ## Problem
 
 The `dsh` source entry point originally used `tsx` to run `apps/cli/src/bin.ts`, with the same third-party loader implicitly handling both TypeScript transformation and the root tsconfig's `paths` resolution. With Node handling TypeScript natively, it does not apply tsconfig path mappings; resolving through package exports would instead mix potentially stale or nonexistent `lib/` artifacts into the source launch.

+
 ## 问题
 
 `dsh` 源码入口原本使用 `tsx` 运行 `apps/cli/src/bin.ts`，TypeScript 转换和根 tsconfig 的 `paths` 解析都由同一个第三方 loader 隐式处理。改由 Node 原生处理 TypeScript 后，Node 不会应用 tsconfig 路径映射；如果改为通过包导出解析，源码启动会混入可能陈旧或不存在的 `lib/` 产物。

+
+> Supersedes [native TypeScript source launch](2026-07-28-dsh-native-typescript-source-launch.md): Node removed the capability that decision was built on.
+
+## Problem
+
+The [native source-launch decision](2026-07-28-dsh-native-typescript-source-launch.md) ran `apps/cli/src/bin.ts` under `node --experimental-transform-types` with a resolve-only paths loader, so Node owned TypeScript transformation. Node 26.0.0 removed `--experimental-transform-types` (the process rejects the flag with `bad option`), keeping only strip mode, and strip mode rejects syntax this source graph requires: vendored Cordis parameter properties (`constructor(private ctx: Context)`), the `@Inject` decorators in `vendor/hmr`, and runtime enums/namespaces throughout `vendor/` and `packages/workflow`. The repository's engines range (`^22.19.0 || >=24.0.0`) includes Node 26, so the native launch chain could not start at all there — and no CI job executed the real launch vector, so the incompatibility shipped silently.
+
+Startup latency also mattered: the off-thread `module.register()` hooks worker serialized every resolution across threads (~440ms of `makeSyncRequest` wait during TUI boot), and the full tsx default (`--import tsx`) pays ~0.4s in its CJS hook's resolution amplification.
+
+## Decision
+
+The `dsh` TUI, Web, and headless source launches run `node --import tsx/esm`: tsx's ESM-only hook owns both TypeScript transformation and tsconfig `paths` projection. `bin/dsh`, the root `dsh`/`demo:tui`/`demo:web` scripts, and the Code Mode TUI overlay use the same vector; `bin/dsh` references the hook and tsconfig by absolute checkout paths (bare `tsx/esm` does not resolve from an arbitrary cwd) and pins `TSX_TSCONFIG_PATH` to the root tsconfig. The CJS hook stays off because the CLI source graph is ESM-only; measured TUI time-to-banner is ~0.7s versus ~1.1s under the full tsx default and ~0.75s under the removed native chain.
+
+`scripts/tspath-loader.ts` and `apps/cli/src/tsconfig-paths-loader.ts` are deleted. With them went the loader's runtime rule of mapping a workspace import only for declared runtime dependencies — tsx applies the `paths` map unconditionally. Declaration completeness now rests on the static gates alone: `verify-cordis-config` for configured bare plugins, and workspace constraints for manifests. (That runtime rule found real bugs: `dsh-plan-mode` and `dsh-tool-tasks` imported `@deepseek-ai/dsh-llm` while declaring it only in devDependencies; fixed alongside this change.)
+
+The node-compat CI matrix (Node 22.19 and 26) gains `dsh-source-launch-smoke` (`apps/cli/tests/source-launch.compat.spec.ts`): a keyless piped-stdio launch of the exact production vector asserting the non-zero-exit TTY refusal. Any future Node change to module hooks or TypeScript handling turns this gate red instead of breaking developers' `pnpm dsh`.
+
+## Alternatives considered
+
+**Keep the native chain on Node ≤25 and branch by version.** Rejected: two transformation semantics (amaro versus esbuild) diverge on edge syntax, the launcher grows version probing, and the node-compat matrix must cover both paths — heavy maintenance for an experimental flag that already changed under us. amaro also rejects the `@Inject` decorators `vendor/hmr` uses, so the native path could not boot the shipped default TUI config anyway.
+
+**Make the source graph erasable-only so Node 26 strip mode accepts it.** Rejected: parameter properties and value namespaces pervade vendored Cordis/cosmokit/loader/schemastery; rewriting them is unbounded churn re-applied on every vendor sync.
+
+**A repo-owned in-thread loader (`module.registerHooks()` + esbuild or `@swc/core` transform).** Rejected for now: prototypes measured ~0.45s (esbuild path untested end-to-end; SWC breaks on `vendor/hmr`'s decorator + namespace merge in both decorator modes), but it means owning transform correctness and a resolve hook that tsx already provides. Revisit only if the ~0.3s gap becomes a real cost; the profiling evidence lives in the PR discussion.
+
+**Run built `lib/` for Node 26 and keep native for 24.** Rejected: loses the zero-build development loop on the newest Node line and mixes source and artifact planes.
+
+## Consequences
+
+- One launch vector across the whole engines range, including future Node lines that change native TypeScript support; the smoke gate enforces it per matrix line.
+- TypeScript transformation is delegated to tsx/esbuild again, reversing the prior note's goal of proving Node-native transformation; that goal is unreachable while vendored sources use non-erasable syntax and Node ships no transform mode.
+- The runtime declared-dependency enforcement in source launches is gone; undeclared workspace imports now surface only through static gates or built-mode resolution failures.
+- Startup improves ~0.4s over the full tsx default (`demo:headless` and ACP keep `--import tsx`; their graphs were not audited for CJS-hook dependence and their launch latency is not on the interactive path).

+
+> 取代[原生 TypeScript 源码启动](2026-07-28-dsh-native-typescript-source-launch.md)：Node 移除了该决策所依赖的能力。
+
+## 问题
+
+[原生源码启动决策](2026-07-28-dsh-native-typescript-source-launch.md)让 `apps/cli/src/bin.ts` 在 `node --experimental-transform-types` 下运行，配合一个只做解析的 paths loader，由 Node 负责 TypeScript 转换。Node 26.0.0 移除了 `--experimental-transform-types`（进程以 `bad option` 拒绝该 flag），只保留 strip 模式，而 strip 模式无法接受这个源码图必需的语法：vendor Cordis 中的参数属性（`constructor(private ctx: Context)`）、`vendor/hmr` 中的 `@Inject` 装饰器，以及遍布 `vendor/` 与 `packages/workflow` 的运行时 enum/namespace。仓库的 engines 范围（`^22.19.0 || >=24.0.0`）包含 Node 26，因此原生启动链在其上完全无法启动——且没有任何 CI 任务执行过真实启动向量，这一不兼容悄然发布。
+
+启动延迟同样是问题：off-thread 的 `module.register()` hooks worker 把每次解析都跨线程序列化（TUI 启动期间约 440ms 的 `makeSyncRequest` 等待），而完整 tsx 默认形态（`--import tsx`）的 CJS hook 解析放大要多付约 0.4s。
+
+## 决策
+
+`dsh` 的 TUI、Web 与无头源码启动运行 `node --import tsx/esm`：由 tsx 的 ESM-only hook 同时负责 TypeScript 转换与 tsconfig `paths` 投影。`bin/dsh`、根目录的 `dsh`/`demo:tui`/`demo:web` 脚本以及 Code Mode TUI overlay 使用同一向量；`bin/dsh` 以 checkout 的绝对路径引用 hook 与 tsconfig（裸的 `tsx/esm` 无法从任意 cwd 解析），并将 `TSX_TSCONFIG_PATH` 固定到根 tsconfig。CJS hook 保持关闭，因为 CLI 源码图是纯 ESM；实测 TUI 到 banner 约 0.7s，对比完整 tsx 默认形态约 1.1s、已移除的原生链约 0.75s。
+
+`scripts/tspath-loader.ts` 与 `apps/cli/src/tsconfig-paths-loader.ts` 已删除。随之消失的还有该 loader "仅为已声明运行时依赖映射 workspace import" 的运行时规则——tsx 无条件应用 `paths` 映射。声明完整性现在仅由静态门禁保障：配置的裸插件走 `verify-cordis-config`，manifest 走 workspace constraints。（该运行时规则确实发现过真实缺陷：`dsh-plan-mode` 与 `dsh-tool-tasks` 导入 `@deepseek-ai/dsh-llm` 却只声明在 devDependencies；已随本变更修复。）
+
+node-compat CI 矩阵（Node 22.19 与 26）新增 `dsh-source-launch-smoke`（`apps/cli/tests/source-launch.compat.spec.ts`）：以精确的生产启动向量做 keyless 管道 stdio 启动，断言非零退出的 TTY 拒绝。未来 Node 对模块 hook 或 TypeScript 处理的任何改动都会让该门禁变红，而不是破坏开发者的 `pnpm dsh`。
+
+## 备选方案
+
+**在 Node ≤25 保留原生链并按版本分叉。** 拒绝：两套转换语义（amaro 与 esbuild）在边缘语法上会分歧，启动器要加版本探测，node-compat 矩阵要覆盖两条路径——为一个已经变动过的 experimental flag 付出沉重维护。而且 amaro 也不支持 `vendor/hmr` 使用的 `@Inject` 装饰器，原生路径本来就无法启动随附的默认 TUI 配置。
+
+**把源码图改成 erasable-only 以适配 Node 26 strip 模式。** 拒绝：参数属性与值 namespace 遍布 vendor 的 Cordis/cosmokit/loader/schemastery；改写是无界 churn，且每次 vendor sync 都要重做。
+
+**仓库自有的同线程 loader（`module.registerHooks()` + esbuild 或 `@swc/core` 转换）。** 暂拒：原型实测约 0.45s（esbuild 路径未端到端验证；SWC 在 `vendor/hmr` 的装饰器 + namespace 合并上两种装饰器模式都会崩），但意味着自行负责转换正确性和一个 tsx 已经提供的 resolve hook。仅当约 0.3s 的差距成为真实成本时再重启；profiling 证据在 PR 讨论中。
+
+**Node 26 运行构建产物 `lib/`，24 保留原生。** 拒绝：在最新 Node 版本线上失去零构建开发循环，且混淆源码面与产物面。
+
+## 结果
+
+- 整个 engines 范围（包括未来改变原生 TypeScript 支持的 Node 版本线）只有一个启动向量；冒烟门禁按矩阵行强制执行。
+- TypeScript 转换重新委托给 tsx/esbuild，逆转了前一篇 note "证明 Node 原生转换可用" 的目标；在 vendor 源码使用不可擦除语法且 Node 不再提供 transform 模式的情况下，该目标不可达。
+- 源码启动中的运行时依赖声明强制不复存在；未声明的 workspace import 现在只能通过静态门禁或构建模式的解析失败暴露。
+- 启动相比完整 tsx 默认形态快约 0.4s（`demo:headless` 与 ACP 保持 `--import tsx`：其依赖图未就 CJS hook 依赖性做审计，且其启动延迟不在交互路径上）。

+# Agent Note: Web details follow the current Session lifecycle
+
+Status: implemented
+
+English | [中文](2026-07-29-web-details-session-lifecycle.zh.md)
+
+## Problem
+
+The details entry is Session-scoped, but its preferred grid width is root-scoped. Selecting a different Session replaced the details content without closing that root preference, so the new owner inherited stale viewing geometry. Hero and other unselected states render no Session-scoped details; they need a derived zero track without becoming false owners in the comparison.
+
+## Decision
+
+`AppFrame` reads the current Session id and its `blank` summary flag from the authoritative Session projection. It records the last non-blank selected id only when that Session can own details, so hero and other unselected states neither trigger closure nor replace the last Session owner; their rendered details track derives as zero without changing the stored preference. The first Session keeps the default details width; returning to the same Session restores its current width; selecting a different Session closes the root-scoped details preference through the layout store before paint. The per-Session chat selection remains owned by the session-scoped store described by the [slot system standard](../architecture/2026-07-22-slot-type-chain-implementation.md).
+
+The layout store is transient and starts details at its default width. It neither reads nor writes `localStorage`, so reload resets both panel widths and needs no Session-baseline exception. Manual close and reopen inside one unchanged Session retain their existing behavior. The lifecycle effect changes neither the [Workspace-owned New Session flow](../feature/2026-07-25-workspace-ui-product-flow.md), composer drafts, Session navigation, nor concession-chain resizing.
+
+## Alternatives considered
+
+**Close details in the New Session click handler.** Rejected because an unselected surface has no Session-scoped details and must not mutate geometry. Closure belongs to the later comparison between two defined Session owners.
+
+**Persist panel geometry per Session.** Rejected because the product contract needs stale context removed, not a new map of remembered widths. Per-Session geometry would also reopen details when users return, contrary to the chosen close-on-leave behavior.
+
+**Preserve persisted layout after the Session baseline is ready.** Rejected because it duplicates startup lifecycle in a presentation component solely to validate stale viewing state. Transient defaults make reload deterministic without a readiness flag.
+
+**Treat every current-projection change as a Session switch.** Rejected because startup materialization, hero, clearing selection, and invalidation are not transitions between two Session owners.
+
+## Consequences
+
+Details is open by default, including when the first Session materializes. Switching to a different Session forgets the dragged details width because close writes zero and reopen uses the contract default. Unselected states derive a zero rendered track while leaving the preferred geometry unchanged; returning to the same Session through one of those states restores its width. Reload forgets sidebar and details geometry. The layout behavior test covers initial defaults, first materialization, direct and hero-mediated Session switches, same-Session return, and the absence of layout storage; the keyless browser e2e drives the same owner transitions through the shipped composition while checking the full grid track and browser errors.

+# Agent Note: Web 详情栏遵循当前会话生命周期
+
+Status: implemented
+
+[English](2026-07-29-web-details-session-lifecycle.md) | 中文
+
+## 问题
+
+详情入口由会话作用域拥有，而其首选网格宽度由根作用域拥有。选择不同会话时，系统会替换详情内容，却不会关闭根作用域的该首选宽度，因此新 owner 会继承陈旧的查看几何信息。hero 和其他未选中状态不会渲染会话作用域的详情；其轨道需派生为零宽度，但不能因此在比较中成为伪 owner。
+
+## 决策
+
+`AppFrame` 从权威会话投影读取当前会话 id 及其摘要中的 `blank` 标志。它只在该会话能够拥有详情时记录最后一个选中的非 blank 会话 id，因此 hero 和其他未选中状态既不会触发关闭，也不会替换最后一个会话 owner；这些状态下，详情栏轨道的渲染宽度派生为零，但存储的首选宽度不变。首个会话保留详情栏的默认宽度；返回同一会话时恢复其当前宽度；选择不同会话时，系统会先通过布局 store 关闭根作用域存储的详情栏首选宽度，再进行绘制。逐会话的聊天选中项继续由 [slot 体系标准](../architecture/2026-07-22-slot-type-chain-implementation.md)所述的会话作用域 store 拥有。
+
+布局 store 是瞬时状态，详情栏以默认宽度启动。它既不读取也不写入 `localStorage`，因此重新加载会重置两个面板的宽度，无需会话基线例外。在同一个未变化的会话内手动关闭和重新打开详情栏，仍保持原有行为。该生命周期 effect 不改变 [Workspace 拥有的 New Session 动线](../feature/2026-07-25-workspace-ui-product-flow.md)、composer 草稿、会话导航或让步链缩放。
+
+## 考虑过的替代方案
+
+**在 New Session 点击处理器中关闭详情栏。** 之所以否决：未选中表面没有会话作用域的详情，不得修改几何信息。详情栏是否关闭，应由随后对两个已定义会话 owner 的比较决定。
+
+**按会话持久化面板几何信息。** 之所以否决：产品契约需要移除陈旧上下文，而不是新增一张保存各宽度的映射。按会话保存几何信息还会在用户返回时重新打开详情栏，与选定的离开即关闭行为相悖。
+
+**在会话基线就绪后保留持久化布局。** 之所以否决：这会仅为验证陈旧的查看状态，在呈现组件中重复实现启动生命周期。瞬时默认值无需就绪标志即可使重新加载具有确定性。
+
+**将当前投影的每次变化都视为会话切换。** 之所以否决：启动时的物化、hero、清除选中项和选中状态失效都不是两个会话 owner 之间的过渡。
+
+## 后果
+
+详情栏默认打开，首次会话物化时亦然。切换到不同会话会忘记拖动后的详情宽度，因为关闭操作会写入零值，重新打开时则使用契约默认值。未选中状态会将轨道的渲染宽度派生为零，同时保持首选几何信息不变；经由这些状态返回同一会话时，会恢复其宽度。重新加载会忘记侧边栏与详情栏的几何信息。布局行为测试覆盖初始默认值、首次物化、直接及经 hero 中转的会话切换、返回同一会话，以及不存在布局存储的情况；无密钥浏览器 e2e 则通过已交付的组合驱动相同的 owner 过渡，同时检查完整网格轨道和浏览器错误。

+# Agent Note: Web UI permission presets and approval answering
+
+Status: implemented
+
+English | [中文](2026-07-23-web-permission-and-approval.zh.md)
+
+## Problem
+
+The web host booted an unconfined agent: `bootHost` composed `dsh-bash-local` and `dsh-fs-local`, so every web session ran with full file access, no approval channel, and no permission control — while the ACP composition had shipped the complete sandboxed product path (sandbox provider + policy home + confined bash/fs + approval + presets) for months. The web wire contract had already reserved the seats — `approval/requested`/`approval/resolved` mux frames, `POST /api/respond` with `ApprovalResponsePayload`, client-side `pendingBuffers` — but the host `respond` was a stub, no answerer bridged `ctx.approval` to the stream, no RPC exposed the permission select, and the PendingCard rendered approvals as visible-but-unanswerable.
+
+## Decision
+
+The web host composes the same sandboxed product path as the acp-agent composition: `dsh-sandbox-local`, `dsh-sandbox-policy`, `dsh-bash-sandbox`, `dsh-fs-sandbox`, `dsh-user-approval`, and `dsh-permission`, with `BootHostOptions.sandbox` supplying the deployment defaults (`mode`, default `workspace-write`; `approvalPolicy`, default `ask`).
+
+`createApiProxy` owns the approval pending registry. Its `approval/request` waterfall answerer reads the approval id from the session's just-appended `approval/asked` audit event (an ask with no audit event is a foreign channel and delegates), mints one stable rpcId per question, broadcasts the answerable `approval/requested` frame to every open mux stream, and replays still-pending frames verbatim on each mux open — the refresh-recovery baseline the contract already promised. `respond` routes by the echoed rpcId, validates `ApprovalResponsePayload` with the existing zod schema, cross-checks the payload's audit correlation against the routed entry, resolves the answerer, and broadcasts `approval/resolved`; the ask's abort signal withdraws the question as `cancelled`.
+
+The permission select rides two new unary RPCs, `session.permissions` and `session.setPermission`, projecting `ctx.permission` into a protocol-owned `PermissionOption` DTO (the ACP bridge precedent: each protocol owns its presentation shape). A permission-less composition serves an empty select and clients hide the control. Idle switches are held last-write-wins in a proxy-side pending map and flushed on `agent/prompt-submit`, because knob events must stay turn-enclosed for durable replay; the shared `hasOpenTurn` fold moved to `dsh-session` and replaced the private copies in `dsh-user-approval`, the ACP bridge, and the proxy.
+
+Client-side, `Session` gained `permissions` and `setPermission`, and approval answering rides the runtime's `PendingWait` carrier. Per the designer draft, a pending approval takes over the composer: `ApprovalPanel` registers as a selector-routed entry of the conversation-declared `conversation.composer` chain (the ui-question pattern), replacing the InputBar with the justification headline, the paired command, and one-shot refuse/allow buttons; the `PendingApproval` domain face in ui-conversation's contract owns the `ApprovalResponsePayload` wire encoding over the carrier, and the broadcast resolved frame settles the wait and restores the composer. Question placeholders stay in the message flow. The sidebar mirrors the blocked state with an amber warning dot that outranks the running ring: the manager tracks per-session outstanding approvalIds (idempotent under mux-open replays, cleared per connection generation so the reopen replay is authoritative) rather than reading Session instances, so the dot lights for sessions never instantiated. The composer's bottom-row chip hosts the `PermissionSelect` control fed through the conversation inject face. The connection fixture mirrors the host: its resident approval is answerable once, and its permission select persists per session.
+
+## Alternatives considered
+
+**Reuse the ACP `session/set_config_option` shape on the web wire.** Rejected: the web contract's unary method registry (`RpcMethodMap` + per-method zod schemas) is its own dialect; a generic config-option surface would bypass the compiler-locked schema table for one select. A dedicated method pair keeps both sides derivable from the signature.
+
+**A session event for pending approvals instead of a proxy-side registry.** Rejected: approval requests are transient interaction state, not durable session data — the `approval/asked`/`decided` audit pair already logs the durable half. Persisting requested frames would re-ask dead questions on replay.
+
+**Registering the answerer only when a mux subscriber exists.** Rejected: the pending entry must survive client disconnects (refresh recovery is the point), so the registry outlives any one stream; a subscriber-gated answerer would fail asks closed during a reload window.
+
+**Optimistic card removal on click.** Rejected: the broadcast resolved frame is the truth; removing on click would hide a question that a rejected receipt or transport failure left standing. The panel disables its buttons locally and re-arms them on failure instead.
+
+## Consequences
+
+Web sessions now start confined (`workspace-write` + `ask` by default) and a sandbox-denial escalation reaches the browser as an answerable card; the deployment can widen or narrow the default through `BootHostOptions.sandbox` without touching the assembly. Question answering shipped separately through the same registry pattern (ui-question over the question pending table). The permission select reads once per mount; live refresh from another client's switch is deferred. Coverage: proxy registry and permission RPC unit suites, session-object and fixture unit suites, and the keyless web smoke exercises the fixture-mode approval answer and preset switch in a real browser.

+Web 承载层启动的是一个不受限的 agent（智能体）：`bootHost` 组合了 `dsh-bash-local` 与 `dsh-fs-local`，因此每个 Web 会话都以完整文件访问权限运行，既无审批通道，也无权限管控——而 ACP 组合早在数月前就已交付完整的沙箱化产品路径（沙箱提供方 + 策略归属 + 受限的 bash/fs + 审批 + 预设）。Web 协议契约其实早已预留了对应位置——`approval/requested`/`approval/resolved` 的 mux 帧、携带 `ApprovalResponsePayload` 的 `POST /api/respond`、client 侧的 `pendingBuffers`——但 host 的 `respond` 只是一个 stub，没有应答者把 `ctx.approval` 桥接到流上，没有 RPC 暴露权限选择，PendingCard 把审批渲染成可见却无法应答的样子。
+
+## 决策
+
+Web 承载层组合与 acp-agent 相同的沙箱化产品路径：`dsh-sandbox-local`、`dsh-sandbox-policy`、`dsh-bash-sandbox`、`dsh-fs-sandbox`、`dsh-user-approval` 与 `dsh-permission`，由 `BootHostOptions.sandbox` 提供部署默认值（`mode`，默认 `workspace-write`；`approvalPolicy`，默认 `ask`）。
+
+`createApiProxy` 拥有审批 pending 注册表。它的 `approval/request` waterfall（瀑布式事件）应答者从会话刚追加的 `approval/asked` 审计事件中读取审批 id（没有审计事件的 ask 属于外部通道，予以委托），为每个问题 mint 一个稳定的 rpcId，向每个打开的 mux 流广播可应答的 `approval/requested` 帧，并在每次 mux 打开时原样重放仍处于 pending 的帧——这正是契约早已承诺的刷新恢复基线。`respond` 按回显的 rpcId 路由，用既有的 zod schema 校验 `ApprovalResponsePayload`，将载荷的审计关联与所路由的条目交叉核对，解析应答者，并广播 `approval/resolved`；ask 的中断信号会以 `cancelled` 撤回该问题。
+
+权限选择依托两个新的一元 RPC，`session.permissions` 与 `session.setPermission`，把 `ctx.permission` 投影为一个由协议拥有的 `PermissionOption` DTO（沿用 ACP bridge 的先例：每个协议拥有自己的呈现形状）。无权限的组合提供空的选择项，client 隐藏该控件。空闲期的切换以后写胜出（last-write-wins）的方式保存在 proxy 侧的 pending map 中，并在 `agent/prompt-submit` 时冲刷，因为旋钮事件必须保持轮次内闭合以支持持久回放；共享的 `hasOpenTurn` 折叠迁入 `dsh-session`，取代了 `dsh-user-approval`、ACP bridge 与 proxy 中各自的私有副本。
+
+在 client 侧，`Session` 新增了 `permissions` 与 `setPermission`，审批应答则依托运行时的 `PendingWait` 载体。按照设计师草稿，处于 pending 的审批会接管 composer：`ApprovalPanel` 注册为由会话声明的 `conversation.composer` 链中一个按选择器路由的条目（即 ui-question 模式），以理由标题、配对的命令与一次性的拒绝／允许按钮取代 InputBar；ui-conversation 契约中的 `PendingApproval` 领域面拥有 `ApprovalResponsePayload` 在该载体上的协议编码（wire encoding），广播的 resolved 帧使该等待落定并恢复 composer。问题占位符仍留在消息流中。侧边栏用一枚琥珀色警示圆点同步呈现这一阻塞状态，且其优先级高于表示运行中的圆环：manager 跟踪每个会话尚未解决的 approvalId（对 mux 打开时的回放幂等，并按连接代次清除，以保证重开后的回放才是权威依据），而非读取 Session 实例，因此从未实例化过的会话也能点亮该圆点。composer 底行的 chip 经会话注入面挂载 `PermissionSelect` 控件。连接 fixture（测试前置数据）与 host 保持一致：它的常驻审批可应答一次，其权限选择项按会话持久保存。
+
+## 曾考虑的替代方案
+
+**在 Web 协议上复用 ACP 的 `session/set_config_option` 形状。** 不予采纳：Web 契约的一元方法注册表（`RpcMethodMap` + 逐方法的 zod schema）是它自成一体的方言；一个通用的 config-option 接口会为一个选择项绕开编译期锁定的 schema 表。一对专用方法让两侧都能从签名推导得出。
+
+**用一个会话事件承载 pending 审批，而非 proxy 侧注册表。** 不予采纳：审批请求是瞬态的交互状态，而非持久的会话数据——`approval/asked`/`decided` 审计对已经记录了持久的那一半。持久化 requested 帧会在回放时重新问出已经作废的问题。
+
+**仅在存在 mux 订阅者时才注册应答者。** 不予采纳：pending 条目必须在 client 断连后依然存活（刷新恢复正是要点所在），因此注册表的生命周期长于任何单个流；一个受订阅者门控的应答者，会让在重载窗口期间关闭的 ask 落空。
+
+**点击即乐观移除卡片。** 不予采纳：广播的 resolved 帧才是真相；点击即移除会隐藏一个因拒绝回执或传输失败而仍然悬置的问题。面板改为在本地禁用其按钮，并在失败时重新启用。
+
+## 后果
+
+Web 会话现在从受限状态启动（默认 `workspace-write` + `ask`），一次沙箱拒绝的升级会以可应答的卡片形式抵达浏览器；部署方可以通过 `BootHostOptions.sandbox` 放宽或收紧默认值，无需触动装配。问题应答已通过同一注册表模式单独交付（ui-question 基于问题 pending 表）。权限选择在每次挂载时读取一次；来自另一个 client 切换的实时刷新暂缓实现。覆盖情况：proxy 注册表与权限 RPC 的单元测试套件、会话对象与 fixture 的单元测试套件，以及无密钥 Web 冒烟测试在真实浏览器中演练 fixture 模式的审批应答与预设切换。

+# Agent Note: Web message IconActions and clocks
+
+Status: implemented
+
+English | [中文](2026-07-29-web-message-icon-actions-and-clock.zh.md)
+
+## Problem
+
+The web chat user bubble already had copy / branch / edit IconActions but no clock. Finalized assistant narration had no under-body action chrome at all, even though the Harness design shows a copy / branch / clock row after the answer settles. Streaming replies must not flash that chrome mid-token. Memoized rows also keep stable props across midnight, so a one-shot `Date.now()` would leave yesterday's messages stuck on `HH:mm`.
+
+## Decision
+
+**User bubbles prepend a date-aware local clock to the existing IconActions row; finalized assistant nodes append a copy / branch / clock row with `margin-top: 16px`; both seats 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.
+
+**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.

+# Agent Note: Web 消息 IconActions 与时钟
+
+Status: implemented
+
+[English](2026-07-29-web-message-icon-actions-and-clock.md) | 中文
+
+## 问题
+
+Web 聊天的用户气泡已有复制／分支／编辑 IconActions，但没有时钟。已定稿的 assistant 叙述下方完全没有操作栏，尽管 Harness 设计稿在回答结束后展示复制／分支／时钟。流式回复不得在 token 中途闪出该栏。经 memo 的行在跨午夜时仍保持稳定 props，因此一次性的 `Date.now()` 会让昨日消息一直卡在 `HH:mm`。
+
+## 决策
+
+**用户气泡在既有 IconActions 行前追加感知日期的本地时钟；已定稿的 assistant 节点在正文下追加带 `margin-top: 16px` 的复制／分支／时钟；两边都在下一个本地午夜重新格式化。**
+
+两边都通过 `formatMessageClock` 格式化 `node.time`：同一日历日 → `HH:mm`，同年更早 → `M月D日 HH:mm`，跨年 → `YYYY年M月D日 HH:mm`。`useCalendarDay` 是组件本地的日刻度（定时到下一个本地午夜），因此 memo 行在日历日变化时会重渲染，且不新增框架 hook。`MessageItem` 把标签放在复制之前（figma `388:20051`）。`AssistantMarkdown` 把它放在分支之后（figma `43:32997`），且仅在 `streaming` 为 false 且已知事件时间时渲染；流式尾部省略该行。复制写入拼接后的 text 块。分支仍是 chrome stub。具备 hover 能力的指针在 hover／focus-within 前保持两条 footer 透明。剪贴板写入与时钟辅助函数放在 `message-chrome.ts`。组装面由 `apps/web/tests/message-actions.e2e.ts`（冷 seed 历史 + aria golden）钉住；aria 归一化把每种时钟形态折叠为 `{{clock}}`。
+
+## 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。
+
+**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。
