+**Inbox lifecycle events carry occurrence identities.** `agent/inbox/enqueue` (an item entered a FIFO), `agent/inbox/update` (a pending queued item was edited), `agent/inbox/dequeue` (the driver claimed one), and `agent/inbox/discard` (pending items were dropped) carry an `InboxItem`: an occurrence-local `InboxItemId`, the accepted `UserMessage`, and the resolved `queued | steering` placement captured at acceptance. The occurrence identity lets observers and reconnect mirrors distinguish repeated sends of the same `MessageId` without reconstructing routing from later status or session history. Injection never touches a FIFO and emits none of these. Every FIFO entry publishes one enqueue and exactly one terminal dequeue or discard; updates are non-terminal. The `dsh-agent` invariant companion asserts this FIFO conservation.

 **Admission accepts next-step input without becoming a turn.** The loop opens a private next-step acceptance window before `agent/prompt-submit`, keeps it open through the turn, and closes it before `turn/end`. Steering and injection received during admission therefore remain together in the outbox and join an allowed turn. 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.

-`wakeup` is the "should the model run" signal, so the inbox distinguishes waking queued work from anything available to dequeue: a lone `next-turn`/no-wakeup item stays parked at idle and rides along the next waking send, and `whenIdle`/`cancel` settle quiescence off the waking signal. Every FIFO exit publishes exactly one lifecycle event, while domain-specific durable facts travel in typed message sources rather than a parallel metadata channel. The direct pending-item representation keeps public lifecycle events correlated without maintaining a second steering wrapper or allowing its durable data to diverge.

+# 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; when such tooling is added, the directory is its required exclusion boundary.

+# 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。

This permits current baseline content on resume without mutating an earlier history event.

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.

 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)`.

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.

+# Agent Note: Address pending queue occurrences for edit and removal
+
+Status: implemented
+
+English | [中文](2026-07-29-addressable-queue-operations.zh.md)
+
+## Problem
+
+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 FIFO. 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 of queued occurrences. A synchronously re-entrant update or terminal event may reach the mirror before its outer enqueue listener; the mirror retains that unseen outcome for the current dispatch and folds it into the enqueue, so listener registration order cannot publish stale content or a ghost row. The wire sends complete `session/queue` snapshots rather than incremental guesses. Reconnect sends the current baseline, and every queued mutation or terminal event replaces it. The client applies no optimistic edit and never retires a row from durable turn events or status changes.
+
+**Queue addresses require a live Agent.** `session.updateQueue` queries only the mounted Agent registry and never resumes a cold session: an `InboxItemId` is process-local and cannot name work after restart or disposal. A missing Agent and a driver-claimed occurrence both return `queue-item-not-found`.
+
+**Web actions address Queue only.** The Host excludes pending steering from `session/queue`; steering retains its existing durable transcript path after consumption. QueueDock exposes edit and delete, but no send-now control. The UI derives queue row and mutation types from the runtime `SessionFace` contract rather than importing the connection plugin, so plugin cooperation continues through services and snapshots. 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.
+
+## 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.
+
+**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.
+
+**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.
+
+**Resume a cold Agent for a queue operation.** Rejected because durable session identity does not preserve the process-local inbox capability. Resuming can only produce `not-found` after creating unrelated live state.
+
+## Verification
+
+AgentLoop contract tests hold prompt admission while editing and removing exact queued occurrences, reject mutations of steering occurrences, and verify the resulting independent turn and terminal lifecycle events. Host schema and proxy tests cover queued-only authoritative snapshots, synchronous re-entrant mutation order, reconnect, cold-Agent rejection, 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.
+
+## Consequences
+
+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.

+# Agent Note（agent 决策记录）：为待处理队列项提供编辑与移除操作
+
+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，但无法编辑或删除其中某一行。`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。
+
+## 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)` 会同步搜索待处理的 queued FIFO。编辑会替换已冻结的内容，同时保留 `InboxItemId`、`MessageId`、来源、唤醒策略和位置。移除会发出该次入队项的终态 discard。steering（中途引导）项和已被驱动器认领的项会返回 `not-found`，因此队列操作绝不会改写活动轮次输入或持久历史。
+
+**实时账本是权威状态。** `agent/inbox/enqueue`、`update`、`dequeue` 和 `discard` 共同维护 queued 入队项的 Host 镜像。同步可重入的 update 或终态事件可能先于外层 enqueue 监听器到达镜像；镜像会在当前分发期间保留这一尚不可见的结果，并在处理 enqueue 时把它合并进去，因此监听器注册顺序不会导致系统发布陈旧内容或不存在的行。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 queued 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，也绝不根据持久轮次事件或状态变化退役队列行。
+
+**Queue 寻址要求 Agent 存活。** `session.updateQueue` 只查询已挂载的 Agent 注册表，绝不恢复冷会话：`InboxItemId` 属于进程本地标识，无法在重启或资源释放后继续指向工作。Agent 缺失和单次入队项已被驱动器认领这两种情况都返回 `queue-item-not-found`。
+
+**Web 操作只面向 Queue。** Host 从 `session/queue` 中排除待处理 steering；steering 消费后仍沿用既有的持久 transcript（文本记录）路径。QueueDock 暴露编辑和删除，不提供立即发送控件。UI 从运行时 `SessionFace` 契约派生队列行与变更类型，而不是导入连接插件，因此插件仍通过服务和快照协作。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。
+
+## 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。
+
+**将待处理 steering 纳入队列变更协议。** 不予采纳，因为 QueueDock 没有 steering 交互，而编辑或删除活动轮次输入会把此功能扩展到当前消费方之外。应由专用 steering 交互负责该投递契约。
+
+**暴露仅协议层的前移操作。** 不予采纳，因为当前没有产品交互会重新排序 Queue。公开一个没有当前消费方的操作，会为了推测性用途引入排序语义和测试。
+
+**为队列操作恢复冷 Agent。** 不予采纳，因为持久会话标识不会保留进程本地的 inbox 寻址凭据。恢复只能在创建无关的实时状态后得到 `not-found`。
+
+## 验证
+
+AgentLoop 契约测试会在编辑和移除精确 queued 入队项时阻塞提示词接纳，拒绝对 steering 入队项的变更，并验证所得独立轮次及终态生命周期事件。Host schema 与代理测试覆盖仅含 queued 项的权威快照、同步可重入变更顺序、重连、拒绝冷 Agent、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、仅文本编辑、保存与取消入口、移除、退役竞态，以及禁用混合内容编辑。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。
+
+## 后果
+
+queued 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 queued 项。编辑会排除混合内容，直至编辑器能够保留每个块；待处理 steering 则不属于此操作接口。
+
+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。

+
+**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.

+
+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。

 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.

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.

-Ordinary turn boundaries are predictable: messages A and B stay separate, and B runs only after A has closed and reached its checkpoint.

 ## 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.

 `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 Queue snapshot; pending steering stays outside this projection. Each row carries its `InboxItemId`, complete editable text when every content block is text, and a flattened preview. `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 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.

+
 ## 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。

 ## 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.
+- **Assistant per-message paging is a reserved slot** — drawn in the design, not implemented. The finalized content IconActions row (copy / branch / clock) ships under text output only; 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.
 - **The approval panel's "Always allow this type" is deferred** — durable grants need a grant-storage design; only allow-once/reject answer today.
 - **TodoPanel truncates long item text to one ellipsized line** — the figma strip has no wrap or expand affordance; full text is not readable inline.
+- **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.
+- **Web exposes pending Queue only** — the Host omits pending steering from the Queue snapshot until steering has its own interaction. A consumed `steering/message` still renders in the durable transcript so external steering remains truthful on replay.

 ## 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。
+- **assistant 逐消息分页是预留 slot**：设计中已有图稿，尚未实现。已定稿的内容 IconActions 行（复制／分支／时钟）只挂在 text 输出下；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。
 - **审批面板的「始终允许此类」暂缓**：持久授权需要授权存储设计；今天只能回答允许一次／拒绝。
 - **TodoPanel 将过长条目截成单行省略号**：figma 条没有换行或展开入口，完整文本无法在行内读完。
+- **Queue 编辑仅支持文本**：包含非文本块的行仍显示扁平化预览，但由于内联编辑器无法保留这些块，其编辑控件会被禁用。文本行进入编辑模式后，删除会替换为保存和取消；Enter 保存，Escape 取消。QueueDock 不提供立即发送控件。
+- **Web 仅暴露待处理 Queue**：在 steering（中途引导）拥有专用交互之前，Host 不会把待处理 steering 纳入 Queue 快照。已消费的 `steering/message` 仍会渲染到持久 transcript（文本记录）中，因此从外部提交的 steering 在回放时仍能如实呈现。
