-The pivotal distinction: **a public input lives only in the Queue** — invisible to the chat panel and to other agents' context — until a single admission step materializes it into History.
+The pivotal distinction is about **publication**, not whether the source has durable identity. A queued user or connector input has one durable source record plus one Queue Entry, but it is not a History member and remains invisible to the chat panel and other agents' context until its first actual delivery materializes that same source into History. An agent-authored source is already public History; its Queue Entry carries only the targets that still need that existing source delivered.
 
 ## The journey of a message
 
 A normal input goes through seven steps:
 
-1. **A source forms the message.** A user, connector, system, agent, or existing protocol owner has already decided the content, purpose, and targets. The kernel does not re-guess intent.
-2. **It persists into the Queue.** The entry point wraps the source envelope as a Queue Entry. Public inputs, agent wakes, and private inputs all enter the *same* durable priority queue, then signal a drain.
-3. **The strict head is selected.** A per-thread drain looks only at the single head the comparator computes. If the target is busy it waits; it never scans for a "better" candidate and never skips the head.
-4. **Admission — the single cutover.** One transaction promotes (or reuses) the entry into a History message, flips each target's ref to `dispatched`, and creates a fixed `processing` response bubble per target. **Only after that transaction commits** is the in-memory Active Run created and the agent called.
+1. **A source forms the message.** A user, connector, system, agent, or existing protocol owner decides the content and explicit targets. All authenticated entrances delegate to common send/admission. For ordinary public input with no valid, routable member mention, it binds the most recent currently-routable completed responder, then the configured default, before Queue admission; fallback does not rewrite the authored body or fabricate a member mention.
+2. **Source and Queue custody persist together.** Common admission resolves explicit intent or the thread/global/product default, saves the per-target policy and exact parent, and atomically writes one durable source record and one Queue Entry with its pending `targets[]`. Public inputs, agent wakes, and private inputs all enter the *same* durable priority queue, then signal a drain. This does not yet publish a user or connector source to History.
+3. **Per-target order is respected.** One per-thread drain scans the stable comparator order. A blocked or retrying source holds its targets, so later work for those members cannot overtake it; unrelated targets can progress. Automatic guidance joins an exact supporting response. A fresh ordinary turn claims one source's complete pending target set, rather than peeling off an idle subset. Explicit singleton Steer and exact unread adoption remain separate cutovers.
+4. **Admission — one source claim, concurrent target cutovers.** One source claim creates or confirms an independent response receiver and Turn Execution for every target in the admitted set. Each durable receiver appends its exact `dispatched` ref, materializes (or reuses) the one source in History, and removes only its target from Queue. **Only after that durable cutover commits** is the corresponding process-local Active Run created and the agent client called. A target that fails before its cutover is restored without rolling back already-admitted siblings; later target executions and outcomes settle independently.
 5. **The same bubble streams.** Output updates only the bubble admission created. A member's internal session rollover, context compaction, or continuation stays inside the agent client and creates no new kernel object.
 6. **One terminal, in place.** completed, failed, or canceled all finalize the *same* bubble; in one durable transaction each structured owner commits its own disposition, and only the follow-up that outcome allows is created.
 7. **Release, then continue.** After the terminal commits, the exact Active Run is released and the drain runs again — so the next queued item never sits silently.

 ## How work gets picked up — and why nothing stalls
 
-The drain is **event-driven — not a timer, not a priority scheduler.** It runs only after something actually changes what is executable at the head: an enqueue, a removal or reorder, an Active Run finishing, an external owner committing a fact about a not-yet-admitted candidate, or startup finding a non-empty queue. A dirty-bit guarantees that events arriving mid-drain force another pass before the drain owner is released.
+The drain is **event-driven, with one owner per thread**. Admission, queue mutation, durable handoff, client readiness, execution terminal, external owner evidence, startup recovery and an explicit retry deadline can request another pass. There is no separate watchdog scheduler. A dirty-bit preserves events arriving mid-drain; native acknowledgement occupies only the exact target, without blocking unrelated members.
 
-The result is a structural invariant, not a watchdog: **it is impossible to sit stably in "queue non-empty, head executable, no Active Run, and no drain."** Nothing can silently pile up.

-## Fallback — when no target is given
+## Targets, policy and replay
 
-Fallback applies **only to a public message at the head, and only when the thread is idle** (no Active Run). It routes to the member of the most recent **completed** response bubble if that member is available; otherwise to the server's default member; otherwise it surfaces a visible delivery failure. Members whose latest bubble is processing, failed, or canceled are not candidates.
+Common send parses ordinary member mentions. Unmatched `@` text remains unchanged and is ignored for routing; mixed mentions retain the recognized members. Ordinary public input with no available target uses the existing completed-responder/default fallback. Fallback never expands private or whisper authorization; A2A line-start handoffs and explicit recipient IDs keep exact identity and report delivery failure instead of choosing another member.
 
-**Explicit targets and private or structured work never fall back.** A failed exact target produces a typed failure and diagnostic — never a silent reassignment to someone else.
+Target and sending-policy snapshots are committed before Queue admission. A same-ID retry reuses the first winning targets and policy, even if the default later changes; a different ID with the same body is a new input. Historical/recovered targetless rows use the existing recovery path. Unknown ordinary body text does not create a warning or waiting state.

 - **Member-internal continuation** — an agent compacting context or rolling its session over to finish the same invocation. This is invisible to the lifecycle: still the same invocation, still the same response bubble.
 - **Protocol-visible A2A handoff** — a completed reply (or an explicit `post_message`) that carries a valid target. It creates a wake referencing the *same* response message — it is **not** copied into a second message — and the next hop begins.
 
-Each hop finalizes **independently and closes only its own `input → target` step.** If agent B, while answering A, mentions D, that does *not* reopen A→B or make A wait recursively for D. On **failure**, custody returns only to the **exact predecessor the source owner names** after disposing that exact invocation — never inferred from a message's author field. Users, connectors, and scheduled or public inputs have no such owner binding and never participate in predecessor return.
+Each hop finalizes **independently and closes only its own `input → target` step.** If agent B, while answering A, mentions D, that does *not* reopen A→B or make A wait recursively for D. An exact A2A **failed** result atomically creates one idempotent `a2a_failure` message-ref control wake for the caller frozen at admission. It points to the original failed response, does not copy its body, and cannot recursively fail back. Completed/canceled/interrupted results do not implicitly re-invoke a predecessor. Structured responsibility is dispositioned only by its own exact owner; it is never inferred from an author field or delivery result.
 
 ## What each participant sees
 
 Users and agents read the **same order**, threaded by the History order key. If A starts first and B finishes first, the final order is still *A's bubble → B's bubble*, not completion order. A `processing` bubble is an **ordering barrier** the agent's read cursor may not cross, so late-finishing work never jumps ahead.
 
-"Processing" means server-side execution is live. It does **not** mean the agent has seen or read the content: body exposure and "handled" are separate facts, each with its own owner.
+"Processing" means server-side execution is live. It does **not** mean the agent has seen or read the content: body exposure and "handled" are separate facts, each with its own owner. Optional `dispatchRef.inputRead` evidence records `pending` or `read`; it does not control Queue membership or create another admission.
 
 ## User controls
 
 Four explicit operations act on a specific entry or run. They are *not* remedies for normal scheduling, and they never pause or reorder the queue:
 
-- **Append** — adds your input to the target's *existing* run; no new run is created.
-- **Steer** — cancels the still-live run for that target, then admits a fresh one.
+- **Guide reply** — adds your input to an exact supported current reply without interrupting it or creating a second run. Eligibility follows the member’s static guidance capability, not whether a run is currently active. A preparing parent retains the exact guidance intent until client readiness wakes the queue; with no parent execution, the server handles the input as ordinary queued work and starts a fresh reply when admissible.
+- **Interrupt reply** — cancels the still-live run for that target, then admits a fresh one.
 - **Cancel queued** — deletes a not-yet-dispatched entry; no run is affected.
 - **Stop agent** — snapshots the exact live agent run(s) and cancels them; the normal `canceled` callback closes the bubble. (Managed commands and jobs are not in this snapshot.)
 
 ## Thread independence
 
-Each thread has its own event-driven drain and its own queue head. Work in one thread never crosses into another's scheduling; anything shared between threads is an explicit, recorded cross-post.

 ## Design principles
 
 The whole model rests on five rules:
 
 1. **One owner per fact.** Every fact — queued input, admitted invocation, body exposure, public result, structured responsibility — has exactly one owner. Everyone else references it; no one copies and re-adjudicates it.
-2. **Change on one cutover.** Order, side effects, and who-acts-next change only when a single durable admission transaction commits.
+2. **Change on one cutover.** A fresh ordinary turn claims one complete source target set; guidance follows its exact response binding; each member's order, side effects, and who-acts-next change only when that target's durable receiver/ref commits. Later target executions and outcomes are independent.
 3. **Don't infer one fact from another.** Dispatched is not seen; settled is not handled; enqueue targets are intent, re-verified at dispatch.
 4. **One terminal per run.** Each admitted run has exactly one in-place result; a committed verdict cannot be undone or duplicated.
 5. **Projections are rebuildable; fail closed.** Avatars, "processing," and refs are all derived from canonical facts. When evidence is missing or ambiguous, omit the dynamic claim and show a diagnostic — never a fake "seen," "working," or "done."

 ## 第 1 层：提及解析
 
-### 什么算可路由的提及？
+### 普通正文与 A2A 的解析边界
 
-**只有行首的 `@handle` 才触发路由。** 提及必须出现在一行的开头（可以有可选的空格或 markdown 前缀，如 `>`、`-`、`1.`）才会触发路由。句中的提及（如"请让 @opus 来 review"）**不会被路由**——它们被视为普通文本。
+普通消息由共同 `send` 调用 `AgentRouter` 解析：匹配现有成员的显式 `@` 可以出现在正文中，未匹配的 `@` 原样保留并忽略；混合有效和无效提及时保留有效目标。解析器检查 token 边界和最长匹配，不用语义分类器猜测普通文本是否意在路由。
 
-```
-@opus 请 review 一下              ← 路由（行首）
-> @opus 你怎么看？                ← 路由（引用前缀 OK）
-- @opus 检查一下测试              ← 路由（列表前缀 OK）
+A2A/callback handoff 复用 `a2a-mentions.ts` 的行首规则：允许前导空白与 markdown/list 前缀，剥离围栏代码块，过滤自调用，最多解析两个不同目标。句中讨论另一位成员不会自动成为 A2A handoff。显式指定 recipient ID 的协议投递保留精确身份校验。
 
-请让 @opus 来 review              ← 不路由（句中）
-邮箱是 user@example.com          ← 不路由（邮箱，token 边界）
+```text
+@opus 请 review 一下           → 普通消息与 A2A 都能识别
+请让 @opus 来 review           → 普通消息能识别；A2A 不作行首交接
+user@example.com              → 普通文本，不是成员 mention
+这段 @后面不是成员             → 原样保留，按无有效目标处理
 ```
 
-### 为什么只认行首？
-
-早期版本尝试过检测句中的"动作提及"（如"让 @opus 去..."），但这带来了误报和歧义。当前设计故意做得严格：你想路由到一只猫，就把 `@handle` 放在行首。简单、可预测、零歧义。
-
-### 预处理
-
-解析前，系统会：
-1. **去除围栏代码块**（` ``` ... ``` `）——代码里的提及永远不路由
-2. **去除行内代码**（`` `...` ``）——同理
-3. **去除 URL**——URL 中的 `@` 不是提及
-4. **去除引号内字符串**——引号内的提及通常是在讨论，不是在调用
-5. **Unicode 规范化**——移除零宽空格和 handle 周围的 markdown 格式
-
-### 限制
-
-- **每条消息最多 2 只不同的猫**（`MAX_A2A_MENTION_TARGETS`）
-- **自我提及被过滤**——猫提到自己会被忽略
-- **最长匹配优先**——`@opus-48` 会在 `@opus` 之前被匹配，防止前缀冲突

-- **`cat_disabled`**：猫存在但标记为不可用。推荐同族替代。

-这些错误以路由警告的形式浮现给调用方猫或用户，不会被静默吞掉。
+共同准入将可识别的成员目标与当前可路由性分开处理。普通公开消息的目标不可用或没有匹配成员时，复用既有 fallback；不为未匹配正文新增 warning、错误卡或等待分支。A2A 明确 ID 与私密收件人不会被普通 fallback 改派，投递失败沿原失败回报闭合。协议身份、权限及收件人可见性校验仍由原入口和执行围栏保留。

-不是每条消息都包含 `@提及`。当用户只是发了"看起来不错，合掉吧"而没有 `@任何猫`，路由器需要自己判断该给谁处理。

-| 6 | **系统默认猫** | 全局兜底猫（通常是主力 Opus） |
-
-### 为什么需要"最近用户提及"？
+| 1 | **当前消息的有效显式 @** | 解析、校验并持久化为 authored targets |
+| 2 | **最近 completed 回复者** | 只接受当前仍可路由的 response target；processing / failed / canceled 不是候选 |
+| 3 | **配置的默认成员** | completed 回复者不可用时的服务端兜底 |
 
-这处理了一个常见场景：用户 @ 了一只猫，猫回复了，用户回复时没再 @。路由器会往回看用户最近几条消息，找到之前在跟谁说话。没有这个机制，每次回复都得显式 @。
+fallback 不改写原始正文或冒充 authored mention。相同幂等 ID 重放复用首次赢得 admission 的目标与发送策略，不随稍后的路由和偏好变化改派；不同 ID 同正文分别处理。
 
-这个扫描故意只检查**用户消息**（不是猫的消息），因为系统自动生成的猫消息（愿景守护报告、跨线程通知等）可能会劫持路由。
+历史／恢复 targetless row 由既有恢复路径处理。新普通消息未匹配的正文 `@` 不制造 targetless 等待；确无可用 fallback 时保留可追溯消息并明确反馈。A2A 和私密输入保持 exact 目标与原失败回报。

-- Agent Client 的 completed final 不另写一条 Agent message：它原位终局 admission 时创建的 response bubble，只解析一次 canonical final；有有效 target 时，同一 terminal transaction 写 `assigned` refs 并创建引用同一 `responseMessageId` 的 Queue wake；

+- Agent Client 的 completed final 不另写一条 Agent message：它原位终局 admission 时创建的 response bubble，只解析一次 canonical final；有有效 target 时，同一 terminal transaction 创建引用同一 `responseMessageId` 的 Queue wake，真正下一跳 dispatch 时才写 ref；
 - CLI output 只从 Agent Client 的 stream/terminal 边进入 History，不经过来源消息的 QueueEntry 封装；`private_input` 来源消息则被直接封装为同一 priority Queue 中的 entry，唤起 exact target，但它本身不创建 History message。
 
-因此 inline `conversation_input` materialize 为 History message 后不会再次进入 Queue。`History → Queue` 只表示一条已经存在的 Agent `post_message` 或 completed response bubble 需要唤起成员时创建 `message_wake + message_ref`；它不复制正文。stream chunk 不参与 target 解析，Stop/failed/canceled 也不会凭残留输出创建 wake。`private_input` 已经是 Queue work：drain admission 时只把它作为 exact 私有输入注入，不再额外生成一条 History message；Agent Client 随后的 stream/terminal 仍走同一 response bubble 主链。

+- Queue `targets[]` 是“尚未实际 dispatch”的唯一调度真相；pending target 不在 History 中预写 ref；

-- Queue custody/body exposure owner 记录 exact target/invocation 何时真正拿到 prompt body，以及随后是否 handled。`assigned`、`dispatched`、processing bubble 或 provider accepted 都不能自动推出 seen/handled；
+- provider presentation owner 可以记录 exact target/invocation 是否收到 prompt projection；它不回写 Queue，也不能由 `dispatched`、processing bubble 或 provider accepted 反推；
 - freshness relevance suppression 只表示同一 source wave 不需要额外 rerun，不证明 sibling 正文已被当前 invocation 投影、provider 接收、seen 或 handled。若当前并行 wave 暂缓 sibling output，incremental projection 必须把 delivery boundary 截在该 output 之前；由不同的后续 public user trigger 发起的新回合再恢复该 output，沿既有 cursor/presentation owner 正常投递；
 - canonical visibility relation 是公开 History 输出进入增量投影的必要事实。每条可发布消息都必须在自身持久 append 的同一原子边界取得唯一 `visibilitySeq` 并进入 thread visibility index；raw timeline/thread ZSET 的 membership 不能替代它。`appendAndObservePriorFrontier` 等特殊写路径也必须满足同一合同。admission 前的 queued user work 不取得 visibility position；
 - ActionSuccessor、AwaitState、TurnExecution 与其他 structured owner 保留 generation、predicate、attempt、predecessor 和 responsibility terminal。delivery terminal 可以触发 owner disposition，但不能替它宣称责任完成；
-- 响应气泡的 `processing / completed / failed / canceled / interrupted` 是公开输出结果。`dispatchRefs` 只是从**实际被投递的公开 History 消息**到 Queue/结果事实的持久 derived projection。对 public conversation，这条 History 消息就是 enqueue 时取得 `sourceRecordId` 的同一记录；admission 前它只投影为 Queue row，不承载头像。transport carrier、structured source owner 与始终隐藏的 `private_input` 只提供 provenance/authority，不是公开消息或头像锚点。ref 不复制 outcome、body exposure、handled 或 typed carrier。

 没有有效目标时，消息或 completed bubble 只公开给用户，不创建 Queue entry，也不猜测下一只 Agent。独立 Agent message 若由 live invocation 产生，携带 `producerInvocationId`；response bubble 已携带自身 `invocationId/targetId`。这些只是内容因果元数据，不能替代 source owner 的 invocation binding。普通 `message_wake` 的 `payload.messageId` 足以让 dispatch owner 查验是否存在对应 structured handoff；action successor 与 event wait 产生的 `private_input` 也只在 Queue 保存 inline payload，typed carrier 仍留在 owner store。任何 owner 都不得等到 terminal 再从“当前 holder”或聊天正文猜 source。
 
 ### 5.4 targets 在 enqueue 时记录、在队首按 entry kind 确认
 
-入口解析结构化 mention 并把当时有效的 exact `targets` 写入 Queue Entry；这只形成 `assigned` target intent，不在 enqueue 时猜默认成员。entry 成为队首后先得到 actual target set，再按 `kind` 处理：
+入口先解析结构化 mention。普通用户输入没有有效显式 target 时，服务端立即用 canonical conversation resolver 从 Chat History 反向选择最近一条 `status='completed'` 响应的当前可用回复成员；`processing / failed / canceled / interrupted` 都不能成为候选，没有历史成员时才使用服务端默认成员。解析结果与 source record 在同一个 Queue admission 中持久化为 pending `targets`，因此 Queue row、Send response 与后续 Steer 从未依赖 Web 猜测或一个暂时的空数组；source message 的 `mentions` 仍只记录作者真正写出的结构化 mention，不伪造 `@`。entry 成为队首后用同一 resolver 重新验证 stored targets，再按 `kind` 处理：
 
-- `conversation_input`：按当前 thread membership 重新验证 stored targets；若结果为空，只有当该 thread 没有任何 Active Run 时才从 Chat History 反向找到最近一条 `status='completed'` 响应气泡的回复成员，并确认该成员当前仍可用；`processing / failed / canceled / interrupted` 都不能成为 fallback 候选。没有历史成员时才使用服务端默认成员；默认成员也不可用时，走 §7.1 的 pre-admission failure transaction，不永久卡住队首。
-- `message_wake`：它只因 Agent completed final / `post_message` 的显式 target 才进入 Queue。target 在 head 时失效必须走 §7.1 typed pre-admission failure；若其 `payload.messageId` 对应的 structured dispatch owner 返回 predecessor route，则交回 predecessor 决定改投或上升，否则只留下公开结果；不能 fallback 到最近成员。
-- `private_input`：必须携带来源给定的 exact target，不允许 targetless；所有 payload 都走相同的 priority Queue 与 admission，只使用 envelope 显式给出的 `urgent / normal`，不因用途获得隐式优先级。Queue 不读取 payload 来判断它属于 action、wait、callback 还是 failure return。target 失效时留下 internal terminal diagnostic 并移除 entry，不写 History message、不 fallback，也不把私有正文暴露给其他成员。若上游另有 source owner binding，owner 独立校验其 generation/current custody；这不改变 Queue 的处理分支。
+- `conversation_input`：仍可用的 stored targets 保持原顺序；成员删除或 availability 变化导致整组失效时，同一 resolver 重新选择最近 completed responder/default。历史 schema、恢复或外部旧 writer 留下的 public targetless row 也只在 head recovery 走这条规则；默认成员也不可用时，走 §7.1 的 pre-admission failure transaction，不永久卡住队首。
+- `message_wake`：它只因 Agent completed final / `post_message` 的显式 target 才进入 Queue。target 在 head 时失效必须走 §7.1 typed pre-admission failure；原 Agent message 保留公开 failure 结果，dispatching member 之后按 exact source×target 反查；不能 fallback 到最近成员。
+- `private_input`：必须携带来源给定的 exact target，不允许 targetless；所有 payload 都走相同的 priority Queue 与 admission，只使用 envelope 显式给出的 `urgent / normal`，不因用途获得隐式优先级。Queue 不读取 payload 来判断它属于 action、wait 还是 callback。target 失效时留下 internal terminal diagnostic 并移除 entry，不写 History message、不 fallback，也不把私有正文暴露给其他成员。若上游另有 source owner binding，owner 独立校验其 generation/current custody；这不改变 Queue 的处理分支。
 
-用户/Connector/定时任务等 conversation input 中的裸 `@`、代码片段、未知成员或解析失败只产生 routing warning，并让 `targets=[]`；warning 在 Queue row 中即可见，输入进入 History 时继续随消息保留。
+普通公开正文中未匹配现有成员的 `@` 原样保留，不产生 warning、特殊等待状态或语义分类；混合 mention 只保留有效目标，没有有效可用目标时走同一公开 fallback。各普通来源遵守相同规则。A2A 的指定 ID／行首路由、`private_input`、whisper 以及其他授权绑定输入保留 exact 收件人；失效目标走已有明确失败回报，不改投默认成员。追加、新回合及排队后迟到失效都必须复验 source 对实际 receiver 的可见性。
 
-因此只有 `kind='conversation_input'` 才能走 targetless fallback。fallback 一旦在队首解析成功，选中的成员就是这次 dispatch 的 actual target；History materialize、processing bubble、Active Run 与头像 ref 必须使用同一 target set，不能继续显示空 target、失效 mention 或 provenance sender。`private_input` 进入同一 Queue、按 comparator 位置等待且必须 exact-target；Agent message ref 也不能借空 targets 制造一个成员 invocation。public targetless input 不会在其他成员仍运行时猜目标。

-FIFO 约束同 priority、未手动定位 rows 的 dispatch 顺序，不要求所有 client 串行执行。M1 被 provider 接受后，drain 可以继续启动 M2；A 与 B 可以并发运行。
-
-Queue 没有 `urgent / normal` 之外的数值等级、kind/system-category prefix 或第二条隐藏队列。Queue UI 只渲染可见 rows；拖拽完成后不是只发送一个含糊的“移动 V3”，而是发送当前 revision 下完整的可见顺序。后端验证集合后把这些 rows 原子写为 `position=0..n-1`；有 position 的 rows 按 position 排在未定位 rows 前，因此用户手动排序是唯一可以覆盖默认 priority/FIFO 的普通路径。隐藏 private rows 不出现在命令中，仍按其显式 priority 与 FIFO 保持唯一相对顺序。
-
-例如 comparator 当前投影为 `[V1, C1, V2, C2, V3]`，其中 `C1/C2` 为未定位隐藏 rows；UI 显示 `[V1,V2,V3]`。用户把 `V3` 拖到 `V1/V2` 之间后提交完整列表 `[V1,V3,V2]`，服务端在同一 revision 原子写入 positions，唯一结果为 `[V1,V3,V2,C1,C2]`。这不是从可见锚点猜隐藏行应落在哪一侧，而是现行 comparator 的明确规则：手动定位集合在前，未定位集合在后；两组内部各有唯一排序。若拖拽期间 Queue 新增、删除或 eligibility 改变，revision/集合校验失败，前端刷新后重试。需要立即作用于当前执行的行为仍必须是带 exact entry 的 Append/Steer，不能由 private kind 暗中获得。

-### 6.4 兼容队首批次：一次 dispatch，不合并消息
+用户 reorder 提交 `expectedQueueRevision + orderedVisibleEntryIds`，同一事务写完整 visible positions；revision/集合/资格变化则拒绝并刷新。hidden private rows 不被客户端寻址，仍按显式 priority/FIFO 排序。有 position 的集合在未定位集合前，所以 `[V1,C1,V2,C2,V3]` 中把 visible 改为 `[V1,V3,V2]` 的结果是 `[V1,V3,V2,C1,C2]`。显式 Steer/Append 的 exact selection 与普通自动推进不同，不能使自动追加绕过上述同目标顺序。
 
-只有 public `conversation_input` 参加队首批次；`private_input` 始终作为 exact 私有输入单独 admission，Agent `message_wake` 依靠 §8.3 的实际未读投影消除重复 wake。`collectCompatibleConversationPrefix` 只取得从当前队首开始的最长兼容前缀：
+### 6.4 一次 drain 一条 source：不合并消息
 
-1. 每个 entry 仍是独立消息，顺序连续且没有被用户显式操作；
-2. routing class 相同：要么都是显式 targets，要么都是 targetless；不能仅因为 fallback 恰好等于某条显式 target 就混批；
-3. 按队首时刻解析后的 exact target set 完全相同；连续 targetless entries 使用同一个 fallback 快照；
-4. 所有目标都可 admission；遇到第一个非 conversation input、不同 routing class、不同 target set、不可解析项或操作边界立即停止；
-5. conversation inputs 分别生成 History message，不拼正文；
-6. 每个 target 只创建一个 Active Run 和一个 response bubble，`inputEntryIds/inputMessageIds` 保存完整独立列表。
-
-因此连续三条 `M1/M2/M3 → B` 可以一次拉起 B，但 History 中仍是三条输入，Queue UI 仍可在 admission 前分别重排、删除或 Steer。batch 是一次 client 调用的输入集合，不是新领域对象，也不改变“一条输入一个 entry”。
+因此连续三条 `M1/M2/M3 → B` 始终由三次 source admission 处理；History 中是三条输入，Queue UI 也可在 admission 前分别重排、删除或 Steer。M1 交给 B 后，M2 的 try-drain 会因 B 仍 active 而无副作用返回；B 终局后既有 completion 信号再次尝试 M2。任何 provider 内部优化都不能把多个 source Queue Entry 合并成一个持久领域对象。

+- 每次 try-drain 只处理一个 head；成功 cutover、pre-admission terminal、enqueue/reorder/remove 与 Active Run 终局都会再次发出普通 drain 信号，直到 Queue 空或 head 被明确阻塞；

-- targetless head 只等到最后一个 Active Run 删除，同一个终局事件会立即重新触发；
+- 普通公开输入已在共同 send 绑定目标与策略；忙 target 由执行终局或客户端就绪事件重新通知 drain。targetless recovery 只处理历史/恢复或无可用目标的状态，不由未匹配 `@` 制造等待项；
 - 若 structured head 因 `insufficient_evidence` 被阻塞，它不是“可执行 head”；exact source owner 的后续 evidence/eligibility mutation 通过第 4 类 post-commit 信号再次触发 typed read，不靠 timer 猜测；
 - drain 运行期间到达的新事件置 dirty bit，不会落在 owner 退出窗口；
 - 持久提交后、调用 `requestDrain` 前进程退出，由启动扫描重新触发。

+一条 `@B @C` 在 Queue 中始终是一条 entry，`targets=[B,C]` 只表示尚未实际投递的目标。初始 enqueue 对完整 target set 原子写入，不产生半条 source 或 ghost target。普通 drain 只有在本轮 exact target set 都可 admission 时才领取整组；B/C 各自写 durable response/ref 后，在同一个 source claim 内独立删除自己并启动 provider。Steer 或未读接管领取 singleton B 时，同样把 entry 原位更新为 `targets=[C]`，C 留给后续 drain。

 Stop Agent 是 typed Agent execution control，不是 Queue control，也不是“取消 thread 内一切工作”。指定 Agent 的 Stop 只选择该 target 当前的 exact Agent Client invocation；thread 级 Stop all Agents 则在同一个 per-thread coordinator 临界区快照当前全部 `kind='agent_client'` Active Runs。managed command/job、独立 child execution 与 registered wait 不属于该集合。两种 Stop 都只对 snapshot 中仍 live 的 exact Agent Clients 发 `cancel(invocationId)`，不自行伪造 terminal，也不提前删除 Active Run。Agent Client 必须把 provider/session-specific cancellation 收敛为该 invocation 唯一的 `canceled` callback；callback 再按 §7.4 原位终局 bubble、让 existing owners disposition 该 invocation 的 typed bindings、释放 exact run。Stop 请求之后到 terminal commit 之前的迟到 stream 由 client fence；terminal commit 之后的任何 chunk/final callback 都是 stale no-op。已终局的 stale run 不在 snapshot 中，操作边界之后新启动的 invocation 也不得被旧 Stop 误杀。
 
 批量 Stop 的 coordinator 临界区只负责 snapshot 与逐一发出 exact cancel，不持锁等待 provider 或 Agent Client 返回。发出 cancel 后即可释放 coordinator owner；随后每个 canceled terminal callback 独立完成自己的 durable closure，并把同一个 drain dirty bit 置位 / 调用 `requestDrain(threadId)`，幂等合并后保证最终至少再运行一轮 drain。Stop 不删除、不重排、不 take Queue entry，也不写 `paused`；因此 Queue 会按原 comparator 顺序继续出队。下一条 entry 即使仍以刚停止的 Agent 为 target，也会创建新的 response bubble 与 invocation，这是新的工作，不表示旧 Stop 失败。若未来增加“暂停队列”，它必须拥有独立的 Queue 级显式操作、持久策略与 Resume 语义，并重新证明 startup/drain liveness；不在本文范围内。
 
-显式操作也保持“一条 multi-target message 是一个 entry”的边界：
+显式操作遵循“一个 source entry、多个 pending targets”的边界：
 
-- entry 已有 targets 时，操作对象是重新验证后的完整 exact target set；不能只取走其中一个 target、把其余 target 留成隐式残片；
-- targetless entry 选择 Append/Steer 时，由用户选择一个 exact target，并在 take transaction 中固定；
-- multi-target Append 只有在每个 target 都有 expected Active Run 时才可 take；multi-target Steer 对每个 target 的当前快照做一次 all-or-none cutover，idle target 不需要取消，busy target 原位 canceled；
-- 若用户只想作用于 multi-target entry 的一部分，必须显式取消并以新的 target set 重发；协议层不偷偷拆 entry。
+- 已有 routed targets 时，modal 默认选中仍 pending 的成员；用户可增删目标，并为每个选中成员分别选择 guide 或 interrupt；
+- 历史/恢复 targetless entry 的首目标绑定与新增 siblings 必须在同一 `targets[]` mutation 完成，不能留下无目标 ghost entry；新 ordinary no-mention ingress 在初始原子 admission 中已经完成首目标绑定；
+- 打开 modal 不写状态；确认时服务端重读 live Queue entry 与 History refs。弹窗打开后已经由未读/其他 dispatch 接管的成员直接跳过；仍 pending 的选择一次原子刷新 `targets[]`，随后每个 target 独立执行，一个 target 的 provider failure 不取消或回滚 sibling；
+- 已移出 thread 或不可用的 target 从本次 live selection 排除；原本不在 thread 的新选择成员只在确认时加入。用户取消一个已经投递的成员没有追溯副作用，不得撤销 History ref、响应气泡或 terminal。

-## 13. 实施顺序
+## 13. 数据迁移边界
 
-1. 先用行为测试锁定 §3.5 五条 laws、QueueEntry 封装、`position → urgent/normal → FIFO` 单一 comparator、完整 visible-order batch reorder 与 stale-revision fail-closed、严格 head drain、targetless fallback、typed source disposition、body exposure/handled 隔离、`dispatchRefs` 可重建性、drain dirty bit 与响应气泡终局；
-2. 让所有 message/Connector/plugin/scheduler/system 生产者提交 `kind + payload + from + targets + priority + ownerAuthProvenance`；priority 缺省 normal，urgent 必须显式给出；public conversation 同时获得稳定 sourceRecordId。入口只校验判别组合；structured owner 在签发 private envelope 前自行决定是否需要 Agent。CLI completed final 只在 terminal transaction 内创建 message-ref wake；
-3. 把 QueueEntry 的 payload 收敛为 inline/message_ref 两种承载，把 sender 收敛为 namespaced `MessageFrom`，并把顶层 entry kind 收敛为 conversation-input/message-wake/private-input；私有协议差异只体现在 inline payload 正文与 Queue 外 owner binding；实现默认 normal、显式 urgent、同级 FIFO、完整 visible-order batch reorder 与 public conversation 兼容前缀批次；
-4. 调整 public conversation 入口为 Queue-first；独立 Agent `post_message` / completed final 直接复用其 History message，并与 message-ref wake 原子写入每目标 `assigned` ref；targetless fallback 只留给 public head；
-5. 建立 pre-admission terminal transaction 与 admission transaction：前者 exact take + History failure result + 已存在 ref 的 `settled`，后者 existing-owner invocation binding + exact take + materialize/reuse 被投递 History 消息 + processing bubble + callback principal + actual-target ref 的 `dispatched`；
-6. 把 Active Run 收敛为 Agent Client exact invocation、responseMessageId 与三组 exact input IDs，并作为 domain active-execution service 的一个 typed input；managed command/job/child execution 继续由各自 owner 参与完整投影；typed source carrier 只留在 owner 的 invocation binding；
-7. 把所有调度触发收敛到 `requestDrain`，包括 structured source owner 对 unadmitted candidate 的 exact eligibility/evidence post-commit signal；由 coordinator 重读 typed owner fact 并竞争 Queue CAS，删除 timer 型正确性兜底；
-8. 接通现有未读 cursor、Queue custody exact body exposure 与 provider presentation receipt：processing barrier + exact input；Agent situation summary 从 canonical Queue/History/execution snapshot 派生，provider adapter 确认接收后才记 presented；
-9. 让 Agent Client 封装成员内部 session/compact/handoff/re-trigger/cancel，并证明跨这些边界仍保持同一 invocation/callback principal；把现有 DraftStore snapshot 与正式 MessageStore append 收敛为同一 response bubble，completed canonical final 解析 target 后把这个既有 bubble 作为下一跳被投递消息，原子创建同 bubble message ref + `assigned` refs；failed/canceled/interrupted 保留 partial body + structured reason，同时按 invocation 提交 typed owner dispositions 与上一跳 delivered-message ref `settled`；
-10. 接入服务端 exact full-entry action projection 与显式 Append/Steer/Cancel queued/Stop Agent；验证 UI/API 读取并重验同一 Queue revision + 完整 target set + owner/run/capability preconditions，Queue action 先整条 take 后 side effect、对应 refs 同事务迁移，并验证 Stop 只 cancel typed exact Agent Client、绝不命中 managed command/job，由 client 正常回调 canceled terminal，不暂停也不删除 Queue；
-11. 保留 Queue custody 的 exposure/seen/handled/attempt、structured owner、active-execution 与 presentation ledger，以及 Queue 的 `urgent / normal` 两级 priority；删除的只是 category-derived rank、Queue pause、ref 反向裁决和多层 timer/fallback。新增 dispatch-ref reconciler 只修 derived projection，不能改写 canonical owners；
-12. 在隔离环境跑完整验收矩阵后执行 quiescent live cutover：先把 content-free `lifecycleWriterEpoch` CAS guard dark-land 到所有 legacy/new writer transaction；语义激活前停止 legacy 新 admission、收敛或持久化在途事务、撤出未受 guard 保护的 binary，再由独占迁移 lease 完成 `legacy → migrating` writer fence、reconciliation 与 `migrating → live` 提交；不得让两套 lifecycle 并行裁决 live work。
+迁移保持 source identity、权限和历史执行事实。新 writer 只维护 source Queue entry 与 pending targets；兼容读取和 schema CAS 不授权重放已接管输入、启用新环境或删除既有用户数据。
 
 ### 13.1 Dark landing 与单次语义激活
 
-实现按三个可独立验证、但不能各自激活 live semantics 的切片推进：
-
-1. **schema/reducer + shadow comparison**：先落新 binding/result/recovery reducer 与新旧结果对比，只读观测，不启用第二个 writer；
-2. **admission cutover**：producer、exact Queue take、immutable owner binding、callback-principal activation、History materialization 与 processing bubble 是一个不可拆的 durable cutover；
-3. **terminal/recovery cutover**：bubble delivery terminal、typed owner disposition、successor/predecessor enqueue、same-generation replay、append-won/apply-crashed compensation 与 startup freshness 是另一个不可拆的 durable cutover。
-
-三个切片可以分别 dark-land，但只有 admission 与 terminal/recovery 都具备并通过 A1–A90 后，live semantics 才一次激活。dark landing 可以沿用 rolling deployment；**live activation 不能是 rolling writer handoff**。激活前置版本必须先把 content-free、monotonic `lifecycleWriterEpoch` CAS guard 部署到每一条 legacy/new admission、terminal 与 migration write transaction；epoch 只裁决哪代 writer 可提交，不复制 Queue、execution 或责任事实，因此不是第四个 lifecycle ledger。任何没有该 guard 的 binary 都不具备 cutover 资格，必须先从流量与进程集合撤出。随后执行 quiescent writer fence：
-
-1. legacy fleet 先停止接受新的 root ingress/admission，但继续让已接收事务提交 canonical terminal，或留下足以让已 dark-land terminal/recovery reducer 接管 exact callback 的持久 outstanding witness；新 ingress 在 activation 完成前保持 blocked，不绕到新 writer；
-2. 等所有已开启的 legacy lifecycle transaction 退出，并撤出所有未受 epoch guard 保护的 binary；无法证明任一 transaction/binary 已退出时，cutover fail closed；
-3. operator/cutover controller 在 canonical store 取得独占 migration lease，以 expected epoch 原子提交 `legacy → migrating`。从这一刻起，所有仍携带 legacy epoch 的 admission/terminal/migration commit 都 typed conflict，不能在 clean scan 后补写；
-4. controller 在同一 lease 与 `migrating` epoch 下执行下述 invariant reconciliation；只有 clean scan 成功才 CAS 提交 `migrating → live`。失败或 crash 保持 `migrating + ingress blocked`，只能幂等续做同一 reconciliation，不能恢复 legacy writer 或双写；
-5. 只有要求并验证 `live` epoch 的新 fleet 才重新开放 ingress。受 guard 保护但版本陈旧的 binary 即使被误启动，也因 expected epoch 不匹配拒绝 lifecycle write。
-
-因此 scan 与 activation 之间不存在仍有提交权限的 legacy transaction；正确性来自 durable epoch CAS，不依赖进程观察、timer 或周期重扫。激活后 legacy resolver 只能保留为 diagnostic/shadow comparison；它不得继续为 live work 重选 current generation、补写 authority 或充当第二 writer。
+Queue schema v2 的迁移目标只有一个：把旧的 per-target Queue records 收敛为“一条 source entry + pending `targets[]`”，同时把已经不属于 Queue 的运行/终局事实留给其 canonical owner。
 
-迁移不得删除现有 Chat History、Queue custody 或 structured owner truth。旧 Queue 记录若绑定的是已公开 Agent/terminal message，转换为 `kind='message_wake' + message_ref`，并按其 exact targets 在同一迁移事务补 `assigned` refs。现行 user/Connector queued record 虽已写入 MessageStore 并对 owner timeline 可见，但只要仍是 `deliveryStatus='queued'`、没有 cat body exposure、没有外部 message permalink/reference，迁移就保留原 message identity 为 `sourceRecordId`，把正文转入 `kind='conversation_input' + inline`，并撤销 admission 前的 History membership/orderKey；这不是删除用户数据，而是把同一 owner-owned record 从 owner-only timeline 投影迁到 Queue Panel。若 queued record 已被 cat exposure、外部引用或其他公开事实观察到，则不能静默改写历史：保留原 History identity、转为 message-ref wake，或 fail closed 留下迁移诊断。对具有可靠 inputMessageIds/responseMessageId 的旧 live work，可以补指向该 processing bubble 的 `dispatched` refs；无法证明 source、target 与 canonical result 唯一对应时只保留诊断并隐藏 working claim，不伪造 ref。旧裸 sender id 必须结合原字段/transport 迁移进明确 `MessageFrom`；不能确认命名空间或认证强度的记录保留诊断，不猜成 Agent/strict。不能可靠转换的运行投影保留 owner truth 与诊断，但不恢复成 Active Run。
+1. 以 `sourceRecordId`（旧数据缺失时使用可证明的 source message identity）分组；同一 source 的 queued/短暂 claimed records 合并为一个 v2 entry，targets 去重并保持稳定顺序；
+2. 新 entry 继承该 source 最早的 `enqueuedAt` 与明确的手工 `position`；payload、`from`、kind 或 source identity 冲突时 fail closed，不猜测合并；
+3. 旧 `processing/terminal/seen/handled/failed` Queue projection不导入 v2 Queue。若 History response、dispatch ref 或 structured owner 已有 canonical fact，保留那些事实并移除 Queue 选择面；
+4. 已公开 Agent/completed-response source 转换为 `message_wake + message_ref`；仍未实际投递的 user/Connector source 保留原 identity 为 `sourceRecordId` 与 inline payload，第一次 actual dispatch 时再取得 History membership；
+5. 每个 v2 write 都携带 schema/version CAS。迁移幂等重放只能得到同一 entry/targets/order；旧 writer 不能在 v2 key 上重新写回 per-target row 或 Queue terminal receipt。
 
-`lifecycleWriterEpoch` 已从 `legacy` CAS 为 `migrating`、且独占 migration lease 生效后，live cutover 才能做 invariant reconciliation：只把“全部 target 都仍是纯 pre-admission pending，且没有任何 admitted/terminal delivery fact”的 legacy entry 导入新 Queue。若同一 target 同时有 Queue membership 与 processing/failed/completed/canceled/interrupted result，保留 canonical History/owner terminal 并删除其 selectable Queue projection；若一个 legacy multi-target row 混有 terminal 与 pending sibling，或证据不能唯一证明整条 entry 仍可执行，则整条 row 进入 non-selectable migration diagnostic，不自动拆成 per-target Queue 残片。后续 Retry/重发（如产品提供）创建新的 entry/attempt，绝不复活旧 row。cutover controller 只有在同一 lease 与 expected `migrating` epoch 下证明不存在 selectable `terminal + queued` row，才能 CAS 提交 `live` epoch；clean scan 不能脱离 writer fence 单独充当激活证据。
+迁移不得删除既有 Chat History 或 structured owner truth。无法唯一证明 source identity、payload、target 集合或公开 History lineage 的旧记录保留诊断并 fail closed；Retry/重发只能创建新的 entry/attempt，不能复活旧 terminal work。

 ## Canonical Owner
 
-F233 owns the ball-custody event-sourcing infrastructure: append-only Event Log as the single internal-canonical truth for ball custody（谁该对一个责任单元行动）, BallCustodyProjection as a rebuildable projection, and the 7-state ball lifecycle (active/blocked/parked/dead/void/zombie/resolved，加 `new` 初始态) enforced by a pure-function state machine. F254 extends the same responsibility boundary in two layers: independent `seenCursor` / `FreshnessAttentionEventLog` provide attention evidence; ADR-041 `FreshnessClosureAggregate` remains canonical only for unfinished/legacy work, while ADR-042 `FreshnessSupplementAggregate` owns bounded additive follow-up responsibility after a completed answer is already MessageStore truth. `FreshnessRelevancePolicy` decides whether a late message creates responsibility from typed provenance only: a cat reply whose `causal.triggerMessageId` was already covered by this invocation's prompt is a same-user-wave sibling and does not create a supplement unless it explicitly targets the current cat. Independent triggers remain relevant. Time windows, prose classification and NLU do not participate. A blocked legacy closure remains active responsibility until every attached withheld invocation has an exact evidence-backed outcome; full accounting terminalizes through `legacy_migrated`, which is distinct from user `dismissed`. F167 Phase S adds a separate TTL=0 `ActionSuccessorLease` responsibility object keyed by tenant + canonical subject + action family + server-authorized slot. S.1-a keeps structured transfer and grounded existing standing on that same CAS: every structured generation persists its authenticated predecessor route; a single-holder ownership rejection increments generation and moves custody back atomically, while a parallel rejection terminates only the rejecting holder and leaves the shared generation in place. A task-backed returned generation may be reattached by the current canonical Task owner to successors only in the same approved child: the proposal proves the initial delegate and current scope lineage, while the exact lease generation—not mutation of `preferredCats`—proves each successor and downstream reporter. A later explicit return retains a typed return edge; a replacement after server-recorded `failed/canceled/unavailable` or `interrupted-after-read` retains a typed replacement edge before clearing prior holder state, so consumers can distinguish lawful supersession from arbitrary generation drift. S.1-b freezes a server-owned typed terminal predicate in each generation: machine-checkable evidence first creates a non-terminal candidate, and only `ActionSubjectTruthResolver` verified truth can CAS a holder to succeeded. Production admission requires both a server verifier and an end-to-end completion producer; the registry opens `review/review_delivered` and task-backed `implement/task_done`. The task capability binds tenant, named owner and task thread from TaskStore before claim, then uses the same task's persisted `done` revision as completion evidence; boot/periodic recovery enumerates active task leases and replays the idempotent completion CAS without another ledger. Canonical `pr_merged` / `ci_passed` resolvers and reserved `test_passed` / `durable_verdict` shapes remain fail-closed until their production completion producers are wired, rather than opening a lease that can never complete. HEAD-fenced predicates accept only canonical full Git OIDs (40/64 lowercase hex). A delivered review coupled to an action lease commits the exact generation/holder/predicate completion before appending the community verdict event; already-verified same-fence retries remain idempotent if event append or projection previously failed. Provider exit 0, response text and Queue delivery remain carrier facts. A server-observed new review HEAD continues the same completed lease at generation+1, rebuilds claim origin/predecessor provenance from the incoming claim, clears prior candidate/outcomes, and leaves the canonical action key unchanged. `returnDeliveryState` only tracks carrier delivery and never adjudicates custody. S.1-c keeps managed-command terminal results and pending return delivery durable until a positive execution carrier exists, then uses boot/periodic recovery sweeps to retry idempotently. Phase T reads only the protocol ball selected by the invocation wake carrier, snapshots its transition truth, and enforces the three-state structured stop decision; it never creates custody or scans unrelated open work. Explicit A2A wake provenance selects the existing `ball:thread:*` dispatch only after its `ball.handed` transition is durably recorded for the target holder；exact managed-command wake provenance selects the existing hold subject。Generic or missing provenance remains `unknown_legacy` and fails closed. For `covered_empty + non_obligation:coordination_terminal`, Phase T may expose a bounded typed `terminal_silent` witness to the existing Queue receipt consumer. For an exact `ball.dispatch_dispositioned`, the stop decision also preserves the canonical `handled | completed` discriminator and event identity. `completed` is terminal-only; `handled` may expose one bounded `dispatch_handled_continuation` witness only after the disposition tool settled and the provider ended without substantive post-tool progress. The witness does not establish or complete owner work and does not reopen the settled carrier. Phase T does not own the durable receipt, parse empty model text, or turn a non-Queue invocation into message custody. The retired legacy comparison is telemetry only. Each responsibility object owns its lifecycle without entering the F233 `BallCustodyEvent` union.

 ## Canonical Owner
 
-F143 provider adapters own raw wire parsing and normalize into the shared AgentService event port; this cell owns the next boundary from provider-neutral semantic event to `BubbleEvent` / human-facing projection. Provider provenance is diagnostic metadata, not the renderer's primary switch. Active foreground, background, hydration/F5, callback, and replay must consume one registry/projector. A structured protocol envelope is visible only through an explicit human-readable projector; unknown/invalid payloads and projector failures retain diagnostics but fail closed instead of becoming raw JSON bubbles. Plain human-readable system notices remain visible.
+F143 provider adapters own raw wire parsing and normalize into the shared AgentService event port; this
+cell owns the next boundary from provider-neutral semantic event to `BubbleEvent` and human-facing

+background, hydration/F5, callback, and replay consume the same semantic projector registry. Unknown or

-F183 / ADR-033 own bubble identity and the single-writer reducer contract for frontend message rendering. This cell owns `(catId, canonicalInvocationId, bubbleKind)` identity, BubbleEvent ingress, hydration merge, IDB fallback, and diagnostics. Each visible cat body may carry one immutable `TurnExecutionMessageProjection`: ordinary replies remain visually ordinary, `routing_guard` is labeled “系统补路由”, and `freshness_supplement` is labeled as a later-message supplement. When a guard only assists preserved first-pass prose, it is attached as `auxiliaryTurnExecutions` to that original bubble and never creates or copies a second body. Terminal lifecycle remains in the ledger glass-box API. Under ADR-042, the published original remains ordinary MessageStore truth. A supplement lifecycle projection is attached by exact `originalMessageId`; pending/running/declined/failed/budget states decorate that original, and a produced supplement is a separate timestamped reply carrying `extra.supplement`. F264 attaches `QueueMessageReceipt` to the original user bubble. It shows carrier admission as delivered, exact child creation as awakened, exact `seenAt` as body read, and `handledAt` as terminal handling, never collapsing those events or calling the latter “received”. The existing `queue_updated` store transition consumes both receipts embedded in surviving Queue rows and additive dispatch-owned `messageReceipts`, keyed only by exact message ID; therefore a terminal withdrawal remains live when the actionable Queue is empty, without a second receipt store or message writer. A typed `terminal_silent` outcome renders a system-owned explanation under the original cross-thread message; empty provider text never creates a cat body or second identity. Its evidence action selects every loaded message in the exact invocation lineage, including supplements, while retaining each message's own timeline identity and position. Live socket and F5 hydration must converge without content/timestamp or log-text guessing.
+Server MessageStore response identity is canonical. `useAgentMessages` routes active/background events to named-message writers; hydration and live updates patch the same server-named message. There is no independent frontend bubble identity or reducer ledger. F183/ADR-033 and supplement projector descriptions remain historical; old stored rows stay readable without creating new supplement work.
+
+F264 delivery presentation now reads actual delivery truth from MessageStore `dispatchRefs[]`. A ref appears
+only after one exact source-to-target cutover and carries `dispatchedAt`, target identity, and the exact
+`statusMessageId`; later settlement updates that same ref from the canonical response lifecycle. Queue owns
+only pending targets and contributes no receipt, processing, exposure, or terminal projection.
+
+The first actual delivery of a user or external inline source materializes its one History bubble. Additional
+targets append refs to the same source message, so a multi-target send never renders duplicate user bubbles.
+Agent-authored sources already in History reuse their existing bubble. A running member that adopts a complete
+queued body through thread context performs the same transition and links the source to its existing response;
+other targets remain pending in the single Queue entry.
+
+`MessageDispatchAvatars` is the two-stage projection of those refs: a dispatched target shows the member avatar,
+hover reveals the actual delivery timestamp, and activation navigates to the exact response bubble. The response
+bubble itself owns `processing`, streamed content, `completed`, `failed`, and `canceled`; a failure retains any
+partial content and appends its structured diagnostic. The source ref never manufactures a second response.
+
+Live socket updates and F5 hydration read the same MessageStore lifecycle. They must converge without content,
+timestamp, Queue receipt, or log-text guesses. Ordinary no-mention user input already has a server-bound Queue
+target and policy snapshot before admission; unmatched ordinary body mentions do not create a targetless waiting state. Either way,
+a user/external source remains outside History until some real dispatch occurs, while a source already in History
+does not need to be moved or copied.
+
+A bodyless processing response renders a lifecycle tip; once content streams, that same response identity
+becomes the bubble. Empty terminal responses use their typed lifecycle notice and remain available to peer
+context. Dispatch navigation follows exact persisted identities without moving the original message or
+copying handled replies beneath it.
 
 ## Use This When
 
-- Adding a provider/origin that creates, streams, finalizes, hydrates, or restores frontend message bubbles.
-- Adding or changing a provider-neutral semantic event, `system_info` protocol projector, visibility rule, or provider provenance handling.
-- Changing `BubbleEvent`, `bubbleKind`, canonical invocation ID handling, placeholder upgrade, or hydration merge behavior.
-- Touching `useAgentMessages`, `bubble-reducer`, `chatStore` message mutation paths, IDB message cache, or bubble diagnostics.
-- Adding or changing legacy closure projections or ADR-042 freshness annotation, supplement status, budget, decline/failure, or reply-chain rendering.
-- Adding or changing F264 receipt rendering, handled-disposition copy, reminder state copy, or lineage focus navigation.
-- Adding or changing message-disposition selector/onboarding, preference-source labels, one-shot override, or author-intent/fallback receipt copy.
-- Adding or changing ordinary/routing-guard/freshness-supplement execution identity, auxiliary execution badges, or ledger hydration links.
+- Adding or changing provider-neutral semantic events, bubble identity, placeholder upgrade, hydration, or
+  replay behavior.
+- Touching `useAgentMessages`, `bubble-reducer`, `chatStore`, `useSocket`, IndexedDB hydration, or
+  bubble diagnostics.
+- Changing historical annotation compatibility, typed child execution badges, or lifecycle tips.
+- Changing dispatch-avatar rendering, delivery timestamps, response terminal outcomes, reminders, or exact
+  response navigation.
+- Changing first-delivery source materialization or delivery-order hydration.
 
 ## Extend By
 
-- Declare which `BubbleEvent` types a new provider emits, where canonical ID comes from, and which `bubbleKind` each event lands in.
-- Map provider wire events into provider-neutral semantics at the adapter boundary; add both a positive provider fixture and a negative fixture proving the wire type does not become the global render contract.
-- Register a semantic kind once for active/background/hydration/callback/replay. Add exhaustiveness and historical raw-payload fixtures so a missing consumer path fails before runtime.
-- Route message mutations through the reducer/single-writer path before adding new direct store writes.
-- Add replay fixtures or invariant tests when extending event kinds, placeholder recovery, or hydration behavior.
-- Keep runtime diagnostics structured enough to identify duplicate stable identities and phase regression.
-- Attach supplement projections only to exact `originalMessageId`; keep the original in the normal timeline and render committed supplement content as a separate reply. UI grouping must never merge original and supplement truth.
-- Attach queue receipts only to the exact original message. Navigate evidence by canonical invocation identities and supplement provenance, highlighting the loaded lineage as a set rather than relocating or duplicating bubbles.
-- Render disposition as an author request, not execution fact. Hide the selector when no relevant invocation is live; show exact exposure/fallback/outcome from custody after send, and clear one-shot state without mutating inherited preferences.
-- Persist and hydrate execution identity through the shared typed projection. A child that owns a visible body uses `turnExecution`; a bodyless assisting child uses `auxiliaryTurnExecutions`. Read terminal status from the ledger API rather than copying mutable status into message text.
+- Normalize provider wire events before they reach the shared semantic projector; add positive and
+  fail-closed fixtures for every new structured kind.
+- Patch only the server-named message through the shared active/background writers.
+- Read historical annotations and attach dispatch refs only by exact persisted identity, never by text or timestamp proximity.
+- Project delivery avatars from MessageStore `dispatchRefs` for both live socket and F5 history; keep the
+  frontend normalizer structural and idempotent.
+- Add paired live/hydration tests whenever dispatch state, lifecycle notice, or timeline ordering changes.
+- Preserve one bubble identity as processing tip upgrades to streamed or terminal content.
 
 ## Do NOT Unify With
 
-- Do not put connector transport policy or platform-specific formatting in bubble identity. Transport owns delivery; bubble pipeline owns rendering identity.
-- Do not make Codex app-server notification names—or any provider wire type—the global UI event vocabulary.
-- Do not use an LLM/skill to guess how protocol JSON should render. Do not fall back to `JSON.stringify` for unknown structured payloads or projector errors.
-- Do not let provider lifecycle IDs become frontend bubble identity. OUTER/canonical invocation ID wins; provider IDs are lifecycle metadata.
-- Do not create new `messages` write entrances without a reducer event and invariant coverage.
-- Do not use IndexedDB as online merge authority. It is a provisional/offline cache.
-- Do not remove or replace a completed original because freshness advanced. Do not discover supplement parents by text/timestamp proximity when exact identity exists.
-- Do not copy handled replies under the receipt, move the original message, or label `seen` as `handled`.
-- Do not keep a meaningless disposition chip visible while all targets are idle, or let composer preference overwrite hydrated message truth.
-- Do not parse prompt text, logs, labels or rendered prose to infer execution kind. Do not render a bodyless routing guard as a second ordinary cat answer.
+- Do not put connector transport policy or provider wire names into bubble identity.
+- Do not render unknown protocol envelopes with `JSON.stringify` or infer semantics with an LLM.
+- Do not let provider lifecycle IDs replace the canonical bubble identity.
+- Do not use IndexedDB as online merge authority.
+- Do not copy Queue lifecycle into MessageStore or derive delivery from pending Queue targets.
+- Do not remove or move an original message when freshness or target lifecycle changes.
+- Do not label Queue admission as delivery, or provider success as handled without exact lifecycle evidence.
+- Do not use content/timestamp proximity to merge supplements, dispatch refs, or terminal notices.

 # Dispatch / Queue
 
 ## Canonical Owner
 
-F175 owns the unified message queue and priority ordering. F185 / ADR-034 own entry-level busy-gate stratification. `TurnExecutionStore` is the TTL=0 lifecycle owner for every real child invoke: provider dispatch starts only after an idempotent `running` create, one immutable terminal wins, and startup interrupts pre-process orphaned running records. `InvocationRecordStore` remains parent/Queue aggregate truth; `InvocationRegistry` remains callback authentication and cannot serve as history. An ordinary queued user message has exactly one carrier here: `InvocationQueue` is its live ordering view, while the revisioned TTL=0 custody embedded in the same MessageStore record is restart truth. F264 projects that same truth into six per-target UI states without creating a second lifecycle. Successful Queue API delete and clear withdrawals publish exact message-bound receipt deltas beside the same ordered `queue_updated` snapshot, including when no actionable row survives; the delta and history hydration both use `projectQueueReceipt` over MessageStore custody. A best-effort notice may set `notified`; a manual reminder records independent `requested / delivered / seen / missed` attempts; exact body exposure binds `seen` to `(messageId, targetCat, childInvocationId, seenAt)`; only that exact child's successful terminal may record either `responded` or `completed_with_turn`, and `handledAt` must follow `seenAt`. The single settlement seam consumes success and explicit user cancellation, rolls ordinary system failure back to the same carrier, consumes action-fenced failure, and retains superseded truth unless an exact source-message CAS has verified replacement custody. A replacement rebind preserves the old message's owner, intent, targets, history, and queued delivery state; no speculative replacement may start before that CAS owns the new entry ID. Startup reconstructs the exact `messageId / entryId / position / target` owner and closes transient reminder/Steer attempts honestly; it does not convert pending execution into delivered-only visibility. Steer means cancel current + restart that exact entry once; reorder is a separate control. F254 keeps ADR-041 typed closure carriers only for unfinished/legacy work. ADR-042 supplement queue rows are allowed only for non-Queue unseen sources and project a distinct durable sequence: `QueueProcessor` resolves current aggregate truth, claims the exact ID, reloads original + required messages, seeds seenCursor, and passes a harness-enforced read-only policy before model start. F167 Phase S keeps action uniqueness in ball-custody and projects `leaseId + generation + dispatchId` onto QueueEntry. S.1-c leaves terminal command/return truth durable until dispatch is positively recoverable. Phase T adds a read-only wake provenance carrier into direct user and queued execution. An explicit A2A `sourceCategory` selects the current thread-ball dispatch, but only after `ball.handed` is durably recorded for the target holder; an exact `hold-ball:*` source selects its hold subject. Generic connectors, missing source records, and failed lookups remain `unknown_legacy` and fail closed through the structured stop gate rather than being guessed from prose. F280 wait delivery persists one immutable carrier in the server-authored `github-wait` message; direct admission copies it to `InvocationRecord`, while busy-thread admission projects it through `InvocationQueue` and QueueProcessor into the same record. Startup re-derives that projection from the exact enclosing MessageStore row, and coalescing includes wait/outcome identity. Queue custody never stores a second copy, and an action-successor wait owner fence stays inside `structured:event_wait` instead of becoming `actionSuccessorFence`. A pre-Gate-4 queued `github-wait` message with no carrier is terminalized failed for its own pending custody targets and never reconstructed as generic connector work; Queue-entry recovery isolates that group and continues unrelated groups in the same pass. For cross-thread messages, one stored body may bind multiple immutable per-target Queue carriers. Carrier admission records delivered; child ledger creation records awakened before body exposure; startup restores each nonterminal carrier independently. A typed Phase T terminal-silent witness may be committed only with the same target's exact body-exposing successful child and successful aggregate. An exact `dispatch_handled_continuation` witness follows the same receipt boundary: only its source message stores the witness, while coalesced siblings settle without inheriting it. QueueProcessor derives a source-free `CollaborationContinuityCapsule` and schedules exactly one same-cat continuation; the capsule carries neither the settled A2A trigger nor its caller/body, so it cannot redispose or replay that carrier. Existing continuation-key dedupe handles identical pending capsules, and `completed` or same-invocation post-tool progress produces no continuation.
-
-F247 cloud-only execution still creates a normal durable child and exposes the exact source body before
-transport. It awaits only a bounded Host receipt/failure, publishes one user-visible transport status, and
-writes `completed` for the exact A2A source. It never waits for the cloud cat's later MCP response and never
-turns missing Host capability into a retryable governance failure.
-
-Gate 5 explicit retry appends one target-local attempt to the existing MessageStore custody only after
-the injected ball-custody authority committer atomically compares the raw Task/action-lease witness and
-every Message custody revision in the same Redis Lua that appends the attempt. `queuedAttemptIdByCatId`
-is then a pure live Queue projection of that accepted durable attempt, and its ID is the Invocation
-idempotency key across start, duplicate clicks, and restart. Receipt history projects every attempt
-without becoming writable state.
-A coalesced cross-thread A2A carrier can aggregate multiple source messages with different attempt IDs,
-so it intentionally projects none; legacy agent retry remains authority-fail-closed instead of guessing.
-
-Gate 6 Batch Steer is a bounded command over the existing Queue, not a new carrier or ledger. The API
-atomically reserves the caller's ordered `entryIds` before preemption, requires one target cat, one intent,
-and one non-unknown owner-auth provenance, then performs one `preempted` cancel and one replacement
-invocation. Eligibility is allowlisted to ordinary user entries: action-fenced, connector/system,
-freshness, continuation/A2A, pinned, `continue_current`, auto-execute, and legacy-unattributed carriers
-fail closed before cancellation. Every selected Queue row enters processing together; QueueProcessor
-passes those exact rows to the existing prompt/body-exposure and settlement seams. F175 adjacent batching
-is bypassed for this invocation, so an unselected neighboring row may run later but cannot enter the
-selected replacement. Provider/infrastructure failure returns every selected row to the same reserved
-group; explicit withdrawal cancels the unstarted reservation without deleting sibling work. The
-reservation marker is process-local coordination and is redacted from Queue API projections; durable
-per-message MessageStore custody remains the only restart truth. If restart loses the group marker before
-replacement start, the persisted per-entry Steer intent disables F175 adjacency: selected rows degrade to
-separate invocations, while an unselected neighbor still cannot be absorbed.
+ADR-043 / F117 own one durable Queue ledger per thread. One source message has one `QueueLedgerEntry`, whose
+`targets[]` is exactly the set of members still awaiting delivery. The entry owns source identity
+(`sourceId` plus `sourceRecordId`), ordering, immutable launch fences, per-target author intent,
+revision, and a short reversible claim. It does not own response processing, terminal outcomes,
+body-exposure receipts, or handled state. `InvocationQueue` is only the in-process scheduling adapter over
+that ledger, never restart truth.
+
+Redis stores source entries in one thread-scoped hash and active entry IDs in the order list. Durable Queue
+state is `queued` plus a bounded `claimed` cutover. A claim is fenced by `claimId`: a failed pre-dispatch
+cutover restores the same entry and position; an actual delivery removes only that target; and an empty
+`targets[]` deletes the entry. Queue retains no processing/terminal tombstone. Retry is a new attempt in the
+owning lifecycle store, not resurrection of finished Queue state. Startup validates persisted rows and
+restores abandoned short claims before scheduling.
+
+MessageStore owns the source body and its actual delivery projection. `dispatchRefs[]` records only real
+source-to-target deliveries, including `dispatchedAt`, response identity, and later settled outcome. A user
+or external inline source remains absent from History while it has no actual dispatch; its first delivered
+target materializes the one source bubble, and later targets extend the same message. Agent-authored sources
+already in History reuse that message. Queue and History therefore meet by exact source identity without
+copying the body or rendering one user message per target.
+
+A complete same-thread unread adoption is the same delivery transition as ordinary dispatch: prove the
+exact running child, remove that exact target from the Queue entry, and append one `dispatchRef` tied to the
+existing response. Other pending targets remain in the same entry. Sparse, cross-thread, oversized-anchor,
+or unproven-child reads do not consume a target. There is no separate Queue `seen`, `handled`, or receipt
+writer.
+
+Routing preflight is not a second chat-message producer. A fail-open `warned` decision remains available in
+structured routing evidence and telemetry while leaving the requested target unchanged; only a `rejected`
+decision may emit a user-visible receipt. When a cat-authored A2A response fails, that response is the only
+terminal History fact. The dispatching member observes it on a later natural invocation through an exact
+source×target History lookup; an exact A2A failed terminal atomically enqueues an idempotent a2a_failure control wake referencing the original failed response, without a second result or recursive fail-back.
+
+Stop is the only user-facing termination. Running truth is the durable `TurnExecution` record plus a
+liveness witness (tracker slot or process owner); in-memory slots, tracker tombstones, and session
+locks are caches and cannot pin a thread busy by themselves. An exact Stop first cancels a live candidate; when
+the durable execution still says running but no controllable candidate exists, the same request reconciles that
+target (retire the pre-start reservation, cancel the running record, release the orphaned lock and slot,
+publish terminal) and returns `reconciled` rather than 409. An incomplete process-owner snapshot (`ps` failure,
+unreadable owner manifests, or a platform without `ps`; no platform compatibility branch) is
+retried server-side and then terminalizes the exact execution as failed through the ordinary dispatch terminal
+path, so ordinary failure propagation runs (source dispatchRef settlement and `delivery_failure` for pre-start;
+the dispatching member later observes either fact through History); no confirmation dialog exists, and
+`force-reset` remains only an internal thread-scoped reconciler. The
+same reconciliation is reused at startup, on projection read, and on Stop (ADR-043 D9).
+
+Steer is the only preemption path. The modal projects current participants plus routed/fallback members and
+joins pending Queue targets with already-dispatched History refs. Confirmation rereads live truth: targets
+delivered while the modal was open are skipped, additions/removals update the source entry, and each remaining
+selected target receives its chosen guide-or-interrupt strategy. Stale presentation state is not itself a
+business conflict. The short claim fences the exact server-side cutover; pre-dispatch failure restores Queue
+state, while provider outcomes after actual delivery settle independently in History.
+
+The default disposition is `next_work` (排队等待) or `continue_current` (立即发送，引导回复). Guide support is
+a static per-member client capability projected by the server; the UI must not hard-code it or infer it from
+local activity. Queue and composer Steer show both guide and interrupt actions, allow a per-target strategy for
+multi-select, and enable guide from static member capability rather than a local liveness guess. Confirmation
+rereads the exact active parent: a present parent receives the non-interrupting append, while an absent parent
+falls back to ordinary Queue admission. Both `exact_active_turn` and `queued_internal_turn` support
+current-invocation guidance. `exact_active_turn` describes the precision of accepted guidance: it is carried by
+the exact visible provider turn, while `queued_internal_turn` carries it within the current invocation. Neither
+capability proves successful delivery or reading. Reading is confirmed separately by optional `dispatchRef.inputRead` evidence; it does not govern
+Queue membership or admission.
+Unsupported default guide preserves the target as `next_work` and never cancels the current execution. Ordinary
+no-mention user input is bound before Queue admission; only historical/recovered or unresolved-availability rows use
+head-time targetless binding. That recovery and every multi-target update mutate the one source entry atomically;
+after actual delivery each target proceeds independently. A successful
+`runtime_replacement` already completed its recovered attempt and must not enqueue a second source-less
+continuation.
+
+F175 owns comparator/order policy and F185 / ADR-034 own busy-gate stratification. `TurnExecutionStore`
+owns each real child lifecycle; `InvocationRecordStore` owns parent/aggregate execution truth;
+`InvocationRegistry` remains callback authentication only. F254 closure and supplement stores retain
+their own authority while Queue rows carry typed launch metadata. F167 action leases and F280 wait
+continuations remain owned by ball-custody stores; Queue may transport their exact immutable fences but
+cannot mint, retry, or reinterpret them. The retired Gate-5 bridge may not recreate completed Queue work.
+F247 cloud-only execution still creates a normal child and settles the exact source without turning a
+transport failure into Queue replay.
 
 ## Use This When
 
-- Changing invocation enqueue/dequeue behavior, priority, queue visibility, queue full handling, or auto-execution.
-- Changing busy-gate semantics for users, A2A, connectors, CI/PR/review tasks, scheduled tasks, or generic external wakes.
-- Adding fairness rules such as "non-agent entries must not be starved by agent chains".
-- Changing F254 legacy successor or supplement enqueue, exact body reconstruction, claim/lease, read-only policy, failure terminalization, sequence budget, or startup carrier recovery.
-- Changing ordinary queued-message persistence, custody CAS, same-invocation handled evidence, restart reconciliation, legacy custody backfill, or exact Queue owner reconstruction.
-- Changing child invocation create/terminal/restart lifecycle, execution kind, parent index, glass-box API, or callback-auth cleanup boundary.
-- Changing F264 receipt projection, handled disposition, lineage evidence, reminder attempts, or Steer-in-progress persistence.
-- Changing author-declared current-work/next-work intent, exact parent exposure eligibility, preference resolution, or terminal fallback.
-- Changing action-scoped multi-mention/cross-post admission order, queue idempotency projection, generation preflight, or stale structured response suppression.
-- Changing managed-command/return recovery dispatch, or the wake provenance passed into the turn-scoped custody stop gate.
-- Changing F280 wait carrier direct/Queue admission, coalescing, restart reconstruction, Invocation persistence, or event-wait projection.
-- Changing exact-target retry custody, attempt history, Queue attempt-id projection, or Invocation retry idempotency.
-- Changing Batch Steer eligibility, exact-entry reservation, preemption, or F175 bypass behavior.
+- Changing Queue admission, target-set mutation, priority, ordering, capacity, claim/commit/restore, withdrawal, or
+  restart behavior.
+- Adding a producer that persists Message and Queue work, or changing one of the three cross-record atomic
+  admission transactions.
+- Changing Steer, append-without-stop, prestart retirement, or the `ENTRY_PROCESSING` conflict boundary.
+- Changing the Queue-to-History dispatch cutover, unread adoption, or source materialization.
+- Changing F254 freshness carriers, F167 action-successor fences, F280 wait carriers, or other typed launch
+  metadata transported by Queue.
+- Changing child execution lifecycle, busy-gate policy, wake provenance, or external connector admission.
 
 ## Extend By
 
-- Reuse `InvocationQueue` for queued work and `QueueProcessor` for execution order.
-- Add source/category/priority metadata to queue entries instead of bypassing queue ordering.
-- Route external automated wakes through `ConnectorInvokeTrigger.trigger()` unless a new architecture decision says otherwise.
-- Keep thread-level vs slot-level busy gates explicit in docs and tests.
-- Treat `freshnessClosureId` as a typed custody carrier. Before model execution, resolve immutable origin, scan through the latest raw frontier, CAS-merge relevant bodies, and then claim the running lease. Missing/terminal closure cancels; incomplete evidence blocks before model execution.
-- Treat `freshnessSupplementId` as a projection-only carrier. Resolve the durable aggregate, require one target + exact lineage/seq, claim before launch, rebuild input from MessageStore, and fail before provider start if `readOnlyToolPolicy` is absent or unsupported.
-- Persist ordinary queued-message responsibility on the same MessageStore record with immutable identity, revisioned CAS, stable ordering, and independent `notified / seen / failed / handled` target sets. Rebuild `InvocationQueue` from that truth on startup and reconcile only exact InvocationRecord evidence.
-- Route every attempt terminal through `resolveQueueEntrySettlement`; change an entry ID only with `QueueCustodyReplacementProof` for the exact queued source, and gate provider start on the committed owner.
-- Derive `QueueMessageReceipt` from custody for both live Queue and F5 history. Keep reminder attempts additive and idempotent per exact message/target/invocation; keep `responded` and `completed_with_turn` as distinct terminal dispositions.
-- Append an explicit retry as a new per-target custody attempt only through the ball-custody atomic
-  authority/custody committer; only its durable winner may reopen Queue and project its exact ID into
-  Invocation. Preserve sibling/old attempts and reconstruct that same ID after restart.
-- Publish Queue API delete and clear receipts as message-bound deltas on the existing ordered `queue_updated` event. Name only the exact affected message IDs and derive every delta from persisted custody after settlement.
-- Persist author disposition on the existing per-target custody. Bind `continue_current` to the exact active parent at admission; only a matching full-body read may expose it, and parent terminal must append a fallback to `next_work` for every still-pending target.
-- Create every child in `TurnExecutionStore` before provider start, pass `executionKind` explicitly, and transition `running` through the store's one-way terminal CAS. Reconcile abandoned running children from the durable ledger, never from logs or callback auth.
-- Treat `actionSuccessorFence` as a typed projection from `ActionSuccessorLeaseStore`. Admission happens before request/message/timer/queue persistence; start and commit both preflight the exact generation.
-- Derive stop-gate wake provenance from typed Queue/action/message-source fields only. User/cron/freshness can be obligation-free; action fences, explicit A2A dispatches, and exact hold sources select one custody truth. Persist the A2A `ball.handed` transition before opening its projection; missing/failed lookups stay legacy unknown.
-- For `github-wait`, load the closed carrier from the exact stored source message, copy it unchanged through Queue and Invocation, and include wait/outcome identity in coalescing. Reject malformed or divergent projections before provider start; leave generic non-wait connectors actionless.
-- For Batch Steer, reserve the complete ordered entry allowlist before preemption, keep one target/intent/provenance, and pass the exact selected rows through the existing QueueProcessor settlement path.
+- Create entries through `QueueLedgerAdmission` and use the deterministic source identity; never allocate
+  one independent Queue identity per target.
+- Use `appendAndEnqueueDurable`, connector adoption, or terminal-response fan-out transactions whenever
+  Message and Queue facts must appear together.
+- Add state transitions to `QueueLedgerStore` with Redis Lua that validates every precondition before its
+  first write, plus matching in-memory and isolated-Redis tests.
+- Keep active-order scans bounded to the order list and join actual dispatch state from MessageStore only
+  when a caller needs it.
+- Project public Queue DTOs from pending source entries; project dispatch avatars and terminal truth from
+  MessageStore/response lifecycle, not Queue fields.
+- Keep source authority in its owner store. Queue fields may transport an immutable fence, but start and
+  terminal commit must revalidate it at the owning boundary.
+- Create every child in `TurnExecutionStore` before provider start and settle child plus response lifecycle
+  truth monotonically.
 
 ## Do NOT Unify With
 
-- Do not collapse user side-dispatch and external automated events into one busy-gate rule. ADR-034 explicitly keeps them stratified.
-- Do not add a second queue for a feature-specific wake path without proving `InvocationQueue` cannot express the priority/fairness requirement.
-- Do not create a supplement carrier for an ordinary queued user message, or treat notice delivery as seen/handled evidence.
-- Do not infer `responded` from invocation success alone, collapse reminder delivery into body-read evidence, or turn `seen` into `handled`.
-- Do not retain a terminal Queue row merely to transport its receipt, persist a second receipt ledger, or reconstruct terminal truth from the removed row.
-- Do not add child arrays or kind enums to the parent InvocationRecord, and do not retain callback-auth registry entries as historical execution truth.
-- Do not treat the in-memory `InvocationQueue` Map as restart truth, and do not call `markDelivered` merely because a queued owner was absent after process restart.
-- Do not turn explicit user cancellation into a blind requeue, or mint/start a recovery replacement before exact custody rebind succeeds.
-- Do not use Steer as a synonym for promote/reorder; Steer cancels current work and restarts the exact durable entry once.
-- Do not let Batch Steer accept non-user control carriers, mint authority, create a second lifecycle store, cancel once per selected row, or reuse F175 adjacency to discover extra rows.
-- Do not treat preference or `continue_current` as seen/handled evidence, leave it unbound to a parent, or let a replacement/same-cat successor inherit the old exposure window.
-- Do not use `urgent` priority for agent-to-agent continuation except the explicit continuation exception. Urgent is for user/system blocking work, not agent chatter.
-- Do not model transport delivery retries here; connector delivery belongs to `transport`.
-- Do not infer catch closure from an untyped existing invocation. Scheduling coverage is not semantic closure and cannot suppress a required successor.
-- Do not let queue removal silently delete supplement responsibility, or let a stale carrier launch after its aggregate became terminal.
-- Do not let ordinary A2A coalesce absorb action-fenced work, and do not let queue state decide action uniqueness or replace eligibility.
-- Do not classify a generic connector or provenance-free historical text mention as `covered_empty`; absence of a typed carrier must remain legacy fail-closed during migration. An explicit A2A source category is typed dispatch provenance, not a text guess.
-- Do not duplicate wait carrier fields into `QueuedMessageCustody`, accept them from a trigger caller, promote their owner fence into action lease authority, or reimplement Gate 5 authority inside Queue transport; the route may run a read-only UX preflight, but custody mutation must use the injected ball-custody atomic authority/custody committer before Queue projection.
+- Do not reintroduce `message.queueCustody`, per-target Queue rows, a second receipt ledger, or startup reconstruction
+  by scanning MessageStore.
+- Do not persist Queue processing/terminal tombstones, body-exposure facts, or handled outcomes. Those facts
+  belong to TurnExecution, MessageStore dispatch refs, and response messages.
+- Do not restore failed, cancelled, interrupted, handled, or withdrawn attempts to Queue. A retry is a new
+  lifecycle attempt; pending targets remain pending only until actual dispatch or withdrawal.
+- Do not concatenate adjacent Queue bodies or let one row absorb another row's message identity.
+- Do not preempt before winning the durable claim, and do not turn Steer into promote/reorder.
+- Do not let Queue decide action uniqueness, wait ownership, freshness closure, connector transport policy,
+  or callback authentication.
+- Do not infer delivery/handled state from notices, provider success, log text, or rendered prose.
+- Do not render fail-open routing warnings as chat messages, copy a predecessor failure result, or enqueue a
+  new `runtime_replacement` continuation after the recovered attempt succeeded.
+- Do not return a full queued body before its exact active-child adoption is durable, and do not retire
+  sibling targets when another target adopts the same source.
+- Do not gate Stop on an in-memory live candidate or answer a user's Stop with 409 while the durable row still
+  says running; reconcile or terminalize the exact target instead, and reserve 503 for persistence failure only.
+- Do not let an in-memory slot, tracker tombstone, or session lock pin a thread busy without a durable
+  `TurnExecution` and a liveness witness, and do not surface force-reset as a standing or stall-triggered user entry.
+- Do not use the in-memory Queue cache as persistence or accept an unvalidated Redis row into scheduling.
+- Do not select ordinary delivery policy from source category; protocol authorization and exact owner fences remain independent.

+The native L0 remains a stable, cached identity/governance surface.

 The resolver caches only immutable owner timelines under `RedisRoutingSignalEventStore.getOwnerRevision()`. A newly appended event increments the shared revision atomically; replay does not. Every resolve still re-runs time-sensitive reduction, so cache reuse never freezes expiry or derived availability.
 
-`unavailable` may reject only when subject scope and active validity are proven. Advisory states never silently reroute. Resolver/store failure returns warned fail-open and an audit event so routing context cannot become a dispatch availability single point of failure.
+Explicit routing queries can explain `unavailable` only when subject scope and active validity are proven. These projections do not reject, delay or warn during ordinary delivery, and do not own ordinary fallback or override exact authorized recipients. Already persisted signal events remain readable; this retirement does not erase historical data.
 
 The user-facing Team surface is a canonical F284 Workspace mode, not a sibling host or an expansion of the current-thread Now surface. Background routing changes update the shared read model and needs-you Activity only; explicit user navigation is required to open Team list or detail.

+# ADR-043: 消息队列 = 独立持久化的有序工单账本
+
+> **Status**: accepted | **Decider**: co-creator | **Analysis**: 布偶猫(opus) | **Implementation**: 缅因猫/砚砚 | **Priority**: P1
+> **Supersedes (设计层)**: F039 / F122 / F175 / F047 中关于队列状态与 Steer 预留的描述
+
+## 背景
+
+F117 将消息投递收敛到持久 Queue、实际 dispatch 与固定 response。旧实现将待投递工作、运行终局和回执混在 Message custody 与内存 Queue 两处，导致恢复与调度重复裁决同一事实；本决策为这些事实划定独立 owner。
+
+## 历史问题（决策背景，非当前实现）
+
+### 1. 队列不持久，真相寄生在 message 上
+
+```ts
+private queues = new Map<string, QueueEntry[]>();   // InvocationQueue.ts:263 — 纯内存
+```
+
+持久的那一份是 `message.queueCustody`，被序列化成 JSON 塞进 message 的 Redis hash：
+
+```lua
+redis.call('HSET', KEYS[1], 'queueCustody', ARGV[1], 'queueCustodyRevision', ARGV[2])
+-- RedisMessageStore.ts:189
+```
+
+而 `QueuedMessageCustody` 的形状本身就是一个队列条目：
+
+```ts
+interface QueuedMessageCustody {
+  entryId: string;                                  // 队列条目 ID
+  revision: number;                                 // 乐观并发版本
+  status: 'queued' | 'processing' | 'terminal';     // 队列条目状态机
+}
+```
+
+**结论：持久队列条目已经存在，只是存错了地方。**
+
+### 2. 双写：13 个字段逐一镜像
+
+| QueueEntry（内存） | message.queueCustody（持久） |
+|---|---|
+| `queuedNotifiedByCatIds` | `notifiedByCatIds` |
+| `queuedAwakenedInvocationIdByCatId` | `awakenedInvocationIdByCatId` |
+| `queuedSeenByCatIds` | `seenByCatIds` |
+| `queuedSeenInvocationIdByCatId` | `seenInvocationIdByCatId` |
+| `queuedBodyExposures` | `bodyExposures` |
+| `queuedFailedByCatIds` | `failedByCatIds` |
+| `queuedHandledByCatIds` | `handledByCatIds` |
+| `allTargetCats` | `allTargetCats` |
+| `steerRequestedByCatIds` | `steerRequestedByCatIds` |
+| `steeredInvocationIdByCatId` | `steeredInvocationIdByCatId` |
+| `authorIntentByCatId` | `authorIntentByCatId` |
+| `queuedFailure*ByCatId` | `targetAttempts` |
+| `queuedAttemptIdByCatId` | `targetAttempts` |
+
+旧实现中相应的——CAS、`-3` lifecycle 冲突码、reconcile、rollback、`restoreDurableEntry`、startup reconciler——**都是维持这两份一致的机器**。
+
+### 3. 旧实现把多目标拆行，导致 UI 与账本身份不一致
+
+```ts
+// retired shape
+return admission.targetCats.map((targetCatId) => createQueueRow(sourceId, targetCatId));
+```
+
+这会让同一条用户消息在 Queue UI 中看起来像发了 N 次，同时又迫使 agent/user/connector 走不同数据模型。正确边界不是“把所有来源都拆行”，而是：**一条 source message 始终只有一条 Queue Entry；目标差异只存在于这条 entry 的 pending target set 与 History 的实际 dispatch records 中。**
+
+## 决策
+
+### D1 — 队列条目独立持久化
+
+按 thread 建持久队列：入队即持久化，重启直接反序列化。**不再寄生在 message hash 上。**
+
+### D2 — Queue 只拥有尚待投递的工作；History 拥有实际投递与响应终局
+
+职责边界：
+
+- **source message**：内容、结构化 `from`、稳定 source identity，以及在 actual dispatch 后取得的公开时间线身份；
+- **Queue Entry**：尚未投递的 `targets[]`、顺序、默认/单目标作者意图和短暂可回滚 claim；
+- **History lifecycle**：每个实际 source→target 投递的 `dispatchRefs[]`，以及对应 response bubble 的 processing/completed/failed/canceled 终局。
+
+Queue 不再保存或投影 `notified/awakened/seen/handled/failed/terminal` 回执，也不保留 terminal tombstone。`deliveryStatus` 只描述 source message 的粗粒度可见性；逐目标事实只能从 History lifecycle 读取。
+
+用户与外部 connector 的 inline source 在尚未发生任何实际投递时不进入公开 History。第一次成功投递会把同一 source materialize 到 History，并追加第一个 `dispatchRef`；后续目标复用同一条 source bubble。Agent source 本来就在 History，不需要重复发布。
+
+公开 History message 的自身执行终态与它能否成为下一跳 source 正交：
+`completed / failed / canceled / interrupted` response 均可记录新的下游 `dispatchRef`，且不得改变自身终态。
+失败传播因此直接引用原 failed response；不复制正文，也不创建第二条失败通知。
+
+### D3 — 一条 source message 只有一条 Queue Entry
+
+`QueueLedgerEntry.id = queueEntryId(sourceRecordId)`，不含 target。`targets: string[]` 是**仍待投递**的集合：投递一个成员只删除该成员；最后一个 target 离开后才删除整条 Queue Entry。多目标不会复制 source message，也不会在 UI 产生多个输入气泡。
+
+`payload.sourceRecordId` 回答“这条 Queue Entry 代表哪一条持久 source record”；`from` 回答“谁写了它”。两者正交，任何一方都不能替代另一方。
+
+### D4 — 单行原子 mutation + 跨 store 单调收敛
+
+Queue 自身由 Lua/CAS 转换保证：`enqueue`、按 target 的 `claim/commit/restore`、整 source withdrawal、以及 `reconcileTargets`。初次多目标 admission 在**同一行的一次写入**中全有或全无；不会留下半组 target 或 ghost row。
+
+实际 dispatch 跨越 Queue 与 History 两个 owner。drain 先按唯一 comparator 领取 source entry；同一 source 本轮
+冻结一个 exact target set，并按以下顺序提交：
+
+1. 为 target set 中每个成员并发创建/确认独立 response lifecycle，并把真实
+   `dispatchRef(targetId, responseMessageId, dispatchedAt)` 写入 History；
+2. 每个 target 的 receiver/ref 持久化后，在同一 source claim 内原子删除自己的 target 并启动自己的 provider；
+   未完成 handoff 的 siblings 仍由原 claim 保护，最后一个 target 删除后才关闭该 row；
+3. 某 target 在第 2 步前失败，只恢复尚未退役的 targets；健康 sibling 已有的 receiver/ref、provider run 与 Queue
+   退役不回滚。若进程故障，重放先 join History，发现 target 已 dispatched 后只做幂等清理，绝不再次唤起。
+
+这个 join 以 exact `sourceRecordId × targetCatId` 为键，并在 Memory/Redis 的 lifecycle terminal + Queue
+transaction 中原子判定；不能先做一次易失 read，再凭旧快照 enqueue。A2A、connector 与恢复路径重放一个
+已消费 source 时，只允许清理残留 Queue target。multi-mention 也必须先创建正文一致的真实 Agent History
+source，再将该 source 与同一 `targets[]` entry 原子 admission；callback response 只是 parent lineage，不能
+让它的 id 指向另一段只存在于 Queue 的 synthetic 正文。
+
+一次 try-drain 最多启动一条 source：按 comparator 顺序找第一条「完整 pending target set 此刻都可 admission」的
+source。等待中的 source（目标被 Active Run 占用、被取消 fence 压住，或重试尚在等待）不满足条件，原样留在原位，
+但不再挡住它后面的 source：只挡住后面与它有共同目标的 source，所以每个目标仍按 comparator 顺序收到 source；等待
+空闲 thread 的 targetless 输入挡住其后全部 source，因为它的目标还未知。只有 comparator head 在解析不出目标时原位
+失败，后面的 source 解析不出目标时等待，并占住其请求的目标。领取不再要求被选 source 是 comparator head；Lua 领取
+本就只校验 row 仍 queued 与 target 匹配。扫描读的是一份快照，并在解析目标时 await，owner 可能在此期间重排；所以
+领取前（中间没有 await）按当前 comparator 复核：排在被选 source 前面的 queued source 必须都是本次扫描已经越过、且
+请求目标未变的，否则本次不领取，重新扫描。该 source 的共享 claim 在所有 targets 已退役，或失败 target 已恢复
+pending 时关闭并发出下一次普通 drain 信号，因此后一 source 不必等待健康 target 的 provider terminal；等待中的
+source 由既有执行终局事件再次触发 drain。
+
+尝试结束时仍留在 Queue 的 source 不立即重试：交接前失败（actual-send preflight 拒绝目标、admission 失败），或
+actual-send 拒绝了其中部分目标（其余目标已交接）。为了不在同一失败上空转，该 source 等到它的重试时间：取本次尝试中
+routing 对被拒目标给出的 `automaticRetryAt`（由 route 在拒绝时回报，因为 targetless source 恢复后不再记得它解析到的
+目标）与逐次翻倍的退避（10 秒起，最长 60 分钟）两者中较晚的时刻，到点由定时器触发 drain；等待期间其余 source 照常
+drain。这个等待是进程内状态，重启后直接在启动 drain 里重试。
+同一 source 的 target set 是一次 fan-out，不以“第一个 target 完成 handoff 后再次 drain sibling”拼成并发。一个 target
+进入 provider 后失败，不回滚已经被 sibling 接受的投递；每个 response bubble 独立终局。
+
+Redis `order` 只索引当前待处理 entry；`messageId → entryId` 只为定位尚待投递的 source，不承担历史 receipt 查询。History 分页与头像投影只读 Message lifecycle。
+
+### D5 — Steer 以实时 pending/dispatched join 为准
+
+Steer 的短 claim 保护“一条 source entry + 本次选择的 pending targets”在跨 I/O cutover 期间不被普通
+drain 并发改写。它仍只是 Queue mutation fence，不把 source entry 升格为 processing，也不保存替补 run
+的终局证据。中断当前回复需要调用 Agent Client，因此不能塞进 Redis Lua；中断或 admission 前失败时，
+claim 按原位置恢复。某 target 一旦完成实际 dispatch，就写 History `dispatchRef` 并从 pending
+`targets[]` 删除，之后由 response lifecycle 独立收敛。
+
+消息默认分发与显式 Steer 是两层：默认设置只提供「排队等待」(`next_work`) 与「引导当前回复」
+(`continue_current`)；产品默认是「排队等待」，用户可以在输入框左侧 `+` 菜单按全局、thread 或单次作用域显式
+覆盖，不依赖当前是否有成员回复。active 时输入区右侧只保留 Stop；有正文时再显示一个普通 Send。Send 只做一次
+Queue admission，不在客户端 admission 后追加第二次 Steer。Steer modal
+固定提供「立即发送，引导回复」与「立即发送，中断回复」。前者只由该成员的静态 client capability 判定是否可选，不从 Web 当前活跃快照猜测；确认后由服务端重读 exact active parent，有父 invocation 时做非中断追加，无父 invocation 时诚实降级为普通 Queue 新运行。`exact_active_turn` 和
+`queued_internal_turn` 都可以表示这种引导能力；前者表示精确当前 provider turn 的承载，不自动证明模型已读。读取证据由可选 `dispatchRef.inputRead` 单独记录。能力由服务端随
+成员信息逐成员投影，前端不得硬编码或从本地活跃态猜测。不支持时 action 禁用，原因只在 hover/focus tooltip
+呈现，不增加常驻解释行；默认 `continue_current` 与显式 Steer 在无 active parent 时都诚实保留为 `next_work`，不自动中断，并由普通 FIFO drain 处理。
+
+普通公开输入在共同 send、原子 Message + Queue 准入前解析有效成员 mention，缺少有效可用目标时用既有 completed responder/default fallback；未匹配的 @ 原样留在正文并忽略，不产生 warning 或特殊等待。目标与显式意图或 thread/global/product 默认策略一起持久快照；同 ID 重放复用首次接纳事实。A2A、whisper 和其他授权绑定输入保持 exact 收件人，不扩大私密可见性。历史/恢复 targetless 工作由正常 Queue recovery 处理。
+
+Steer modal 可多选，成员候选为 thread participants、路由目标与 fallback 的并集去重；fallback 直接读取 Queue admission 使用的同一 resolver 投影，Web 不另算。每位成员可以分别选择 guide 或 interrupt。
+
+打开 modal 只读取快照，不写状态。确认时客户端提交“打开时 pending targets + 当前选择”；服务端重新读取：
+
+- 当前 Queue `targets[]`；
+- History 中已存在的 `dispatchRefs[]`；
+- 当前 membership/availability。
+
+已经被未读接管或其他 dispatch 投递的成员直接跳过，不能复活；用户从旧快照取消一个已投递成员也没有副作用。仍 pending 的 remove/add 在同一 source row 上合并，新加入成员只在确认时加入 thread。普通状态变化不是整批 revision conflict；每个仍可执行 target 随后独立 guide/interrupt，失败不回滚 sibling。
+
+### D6 — 副作用出口不再承担 freshness 门卫；专用 continuation 仍是显式载荷
+
+F254 Phase A HELD、B1 MCP-result piggyback 与 B2 hold-ball reminder 已由 #1398 退役。callback/MCP 写工具
+是纯发送原语：不在 `post_message` 时检查 inbox、不阻止发送、不接受 `acknowledgeHeld`，也不在工具结果中
+注入读取教学。运行中正文由所选 carrier 的真实能力承接：live carrier 可向 exact active session append 或
+interrupt；单轮 CLI 不谎报 append，消息继续 pending 并由正常 FIFO drain 开下一轮。
+
+这不等于删除独立的 scheduled/freshness/continuation 工作。它们若由自己的 owner 显式创建，仍以 typed Queue
+payload 写一次、起跑读一次，并由对应 store 重建；这些字段是任务输入，不是 `post_message` 的隐藏状态机，
+也不得重新生长成 Queue receipt。已证明纯写不读的 `freshnessRequiredFrontierMessageId` 继续删除。
+
+成员接入方式只有顶层 canonical `carrier`。兼容读取只在配置边界执行
+`carrier → legacy top-level transport → cli`；下游 provider/capability/UI 不得再读旧字段或全局环境开关，
+且一个 carrier 的失败不得静默 fallback 到另一个。
+
+### D7 — Queue 没有 terminal row；重做是新的用户意图
+
+目标一旦实际 dispatch，就从 pending `targets[]` 离开。`handled / failed / interrupted / canceled` 属于 response lifecycle，不回写 Queue；source withdrawal 则在 source lifecycle 写成 canceled 后删除尚待投递的整条 Queue Entry。
+
+用户若要重做失败事项，应发送新消息或执行明确的新动作，由生产者产生新的 source/attempt。旧 response、dispatchRef 与 wait carrier 只保留原 attempt 的终态证据，不能充当 retry token。
+
+### D8 — 完整正文读取就是一次真实投递
+
+无 filter 的完整 thread-context 读取若要返回一个带持久 Message 的 same-target `conversation_input` queued
+正文，服务端必须先验证 exact running `TurnExecution` 与同一个 `LifecycleActiveRun`，再把该 source 的 exact target 接管到现有 response：
+
+1. claim exact row；
+2. 在 live Active Run 预留 source/entry，并将 source Message 单调推进到 `delivered`；
+3. 把 source message/entry 持久写入该 response lifecycle；
+4. 从 Queue Entry 的 `targets[]` 删除该 target；不写 Queue `seen/handled` 镜像。
+
+History publication 失败时必须撤销 live 预留、restore claim。`active_run_missing` / `state_changed` / `lifecycle_conflict`
+都是良性竞争：只从本次 payload 剔除尚未接管的 queued 正文并照常返回其余 History，不把整次读取变成
+409。只有持久层不可用才返回 503。接管一旦写入 History，后续失败不得把同一 target 放回 Queue；重放通过 dispatchRef 幂等收敛。`queued_seen` / `queued_handled` 仅可保留为兼容 telemetry 名称，不能成为 Queue 字段或恢复 authority。
+
+A 读取只从同一 entry 删除 A，B 继续留在 `targets[]`；B 后续读取再删除 B。第一只猫接管后
+Message 已进入成员可见 History，其他 target 的 Queue 责任仍由同一 entry 追踪。无 Message 的行以及
+带 `actionSuccessorFence` / `waitContinuationCarrier` / scheduled/freshness/continuation custody 的行保留 read→seen
+语义，不由 History 读取接管；稀疏读取、跨 thread 读取、oversized anchor 或无法证明 exact active child
+的请求都不得接管。
+
+本决策取代 F254 D1.2 的旧“两阶段 seen，成功后 handled”实现约束；旧段落只保留为历史设计记录。
+
+### D9 — 停止是对持久执行真相的权威终态化，投影不能反过来卡住它
+
+> 来源：co-creator 2026-09-03 worktree 验收决策（thread `thread_msr51149hym0i79f`）。取代 F220 Phase 3「force-reset 逃生口」作为用户概念的地位。
+
+用户只有两种状态（在运行 / 未运行）和一种动作（停止：单只猫 / 全部）。**停止的成功判据是投影进入「未运行」**；进程是否真的退出由服务端在后台保证。用户不需要区分「正常停」与「强制重置」，也不需要理解逃生舱。
+
+1. **「在跑」的真相 = 持久 execution/response lifecycle + 活性见证**：TurnExecution `running` 与 response lifecycle 是持久真相；Queue 的 `claimed` 只覆盖 admission 的短可回滚窗口，不能冒充执行态。tracker 槽位、`processingSlots`、session 锁只是内存缓存与活性见证，**单独不能构成 busy**。
+2. **停止阶梯（服务端自动升级，用户不选机制）**：exact 活候选 → 现有取消链（abort / `terminateExact` / 释放本猫锁与槽位 / 写终态）；无活候选但目标仍投影为在跑 → 同一请求就地对账（退 pre-start 预留、running 记录置 canceled、释放孤儿锁与槽位、广播终态）并返回 `reconciled`；**对自己拥有的执行永不 409**。进程快照不完整（`ps` 失败 / owner manifest 目录损坏）时，服务端有界重试快照后仍不可用 → 走普通 dispatch terminal：该 exact execution 及其 response 行按 `failed`（reason `control_plane_unavailable`）终局，投影进入未运行，并沿 F117 Phase C/H 收敛：源消息 dispatchRef settle 到该失败 response（`settleLifecycleResponseInputs`）；exact A2A caller 由引用该 response 的幂等 Queue control edge 及时唤起，其他观察仍在 dispatching member 下一次 invocation 反查该 exact 终态；pre-start 尚无 response 行时走 `delivery_failure`。重做只来自新的用户意图（INV-C7），系统不替用户重新拉起。只有持久层不可用（终态写不进去）才 503。**不做平台兼容分支**：Windows 没有 `ps`、子进程不可观测，同样落入这条 fail 分支收敛（快照不可用 = 无法确认 = failed 终局 + 后续 History observation）；本 ADR 唯一保留的兼容是旧 chat message 的 `from` 读取（A.5 `messageFrom`）。
+3. **没有任何确认弹窗**：用户只关心运行态与终态，不需要理解「无法确认进程状态」。`ForceResetDialog` 退役；`/force-reset` 只作为服务端内部 thread 级对账实现，没有用户入口。终态行不复活（D7）保证迟到输出无法回写已终局的气泡；detached host 由 supervisor 收敛（F220 KD-8），有界。
+4. **同一段对账三处复用**：启动（`StartupReconciler`）、投影读取（read-repair：running 记录 + 无 tracker + 进程快照 complete 且无 owner + 超出 pre-start 窗口 → 以 `execution_owner_lost` 终态化；快照不 complete 时不动）、停止（第 2 条）。已离开 Queue 但从未安装 provider tracker 的 pre-start attempt 超时，以 `prestart_timeout` 正常失败终局；父 InvocationRecord 只有在没有 sibling tracker / process-owner 活性见证时才随 child 终局。
+5. **前端**：权威投影稳定即信；旧 socket busy 标记自愈，不再有「运行状态待确认」死角与基于卡死的强制重置入口。
+
+历史根因：F220 Phase 2 报告（#972）已定性为「多 liveness SoT 无收敛点」；F194 读模型、TurnExecution 持久子真相与本 ADR 的账本已关闭进程内的绝大部分分叉，剩余只有基础设施故障（Redis / API 进程）一类，归 reconciler，不归用户。

+`prestartRetirement` **不消失**。窗口是 `invocationRecordStore.create` → `invocationTracker.startAll`，中间包含 routing/visibility 预检、前缀吸收、session 准入。这个「已经 admission、但 tracker 里还没有」的空档由 **I/O 本身**造成，不是 Queue 持久状态，进不了 Lua。
+
+它会从 Steer 专用标记收敛为同一次原子 Queue claim 的通用 `retiringGroupId`，用于关联一起进入 pre-start 窗口的 FIFO prefix entries；它不表示多目标 fan-out。
+
+### D10 — 公开结果、失败控制边与普通 continuation 分工
+
+canonical response / `delivery_failure` 是唯一公开结果，source `dispatchRef` 是其逐目标关联。不得复制 failed
+正文或另造 system result。A2A target 进入 **failed** terminal 时，同一持久事务额外提交一条引用该 response、
+指向 exact caller 的幂等 Queue-only `a2a_failure` 控制载体；它只负责及时触发 caller 消费权威结果，消费 route
+必须禁止递归 fail-back。completed/canceled/interrupted 不自动创建 caller work；target 显式发给 caller 的新消息
+仍是普通 dispatch，其他自动 continuation 必须由 hold/eventWait/action-successor 等显式 owner 创建。控制载体
+不登记为失败方新发起的 outbound business dispatch，也不进入失败方 caller view。
+
+本约束的根因教训：Queue-only 控制载体不是第二条结果。曾把“失败只公开一次”错误推广为“失败不产生任何
+predecessor Queue work”，导致 canonical failed response 已落 History、caller 却没有触发器。单一真相源约束复制
+状态，不禁止引用权威状态的幂等调度边。
+
+同理，系统诊断不能因为使用 `system_info` envelope 就自动成为 History message。未分类 warning 与 routing
+fail-open `warned` 留在 telemetry；只有要求用户采取具体动作的 warning 显式声明 `user_action_required` 后才能
+持久呈现，自动重试等短暂状态只进入 live provider status。route-syntax、verdict-without-pass、void-hold 等
+Agent protocol correction 走私有 feedback / 下一 turn prompt / telemetry，不向用户对话追加提示气泡。这样
+“对话消息”由用户行动价值决定，而不是由入口类型或字符串 if/else 决定。
+
+客户端单 runtime 在 caller 串行 slot 中维护一份**该成员自己的 outbound dispatch view**。它以
+`(owner, thread, caller, sourceMessageId, targetId)` 为 item key。每个 item 保存严格单调的 `revision`、最近一次
+成功进入 caller prompt 的 `presentedRevision`，以及当前 Queue/History 已无法反查的最小解释事实：
+`firstAddedBy(initial|steer|unknown)`、`selectionChange(added|removed)` 与
+`selectionChangedBy(initial|steer|queue_withdrawal|unknown)`。这些字段不参与执行裁决；当前进程首次
+看到重启前遗留 target 的 remove/actual 事件时，最初来源不可证明，必须写 unknown 而不是猜 initial：
+
+这里的 source identity 不能被执行优化抹平。`M1→B` 与 `M2→B` 永远是两个 view items、两条分别属于
+M1/M2 的 dispatchRefs；Queue admission 逐 source 处理，即使其它显式机制让一个 response 反向引用两条 source，
+也不能把 source lifecycle 合并成一次 attempt。相同 source 的 B/C 则共享一个 Queue row，但各有独立 ref/result。
+
+- 一条 Agent source 成功提交 Queue admission 时，把当时的 exact targets 加入 view；同一 caller 随后发送新的
+  source，只追加新 source×target items，不覆盖前一条仍 open 的 dispatch；
+- Steer 对尚未 actual dispatch 的 target 做 remove/add 时，按已经提交的 Queue mutation 更新同一 item revision 与
+  selectionChange；C 离开 Queue 后仍可说明“由 Steer 移除”，E 可说明“由 Steer 新增”；
+  已 actual dispatch 的 target 仍由 History ref 裁决，不能被旧 Steer snapshot 改写为未投递；
+- actual admission、direct `delivery_failure` 与 response terminal 只触发对应 item 的 revision 更新；dispatchRef
+  关联已经发生的投递或投递失败事实，不代表 target 预期，也不能仅凭 ref 存在断言 provider 已收到消息；实际状态和
+  response identity仍在读取时从 Queue + source `dispatchRefs[]` + canonical response 反查，view 不复制它们。
+
+因此 `A→B/C/D` 进入 durable Queue 后，Steer 移除 C、保留 D、加入 E，可以在 A 的 view 中表达为：C 未投递且已移除，D 已实际
+投递，E 是新增待投递/已投递；B 随后在 actual admission 前失效时通过 canonical `delivery_failure` 表达。无法解析出 canonical
+targetId 的 mention 只进入 routing diagnostic；durable Queue admission 前被 routing preflight 拒绝的 canonical target
+由本次发送结果立即返回 typed fail-back，二者都不伪造 view item。初始 admission、Steer 与 actual result 都调用同一
+view update primitive，不为各入口建立平行状态机。
+
+caller 下一次自然 invocation 先对所有保留 items 逐项反查：Queue 仍含 target 表示 pending，History ref 为 open
+表示 executing，settled ref 读取 canonical terminal response；最近一次已提交 view mutation 为 remove 且没有 actual
+ref 时表示 not_delivered/withdrawn。校验候选快照仍有效后，以 canonical fingerprint 变化推进 revision，再只把
+`revision > presentedRevision` 的未呈现变化加入 prompt。投影开始时冻结 `includedRevision`，最终正文必须绑定该快照；异步查询期间 revision
+变化时必须重读或保留待核对，不能读取最新 revision 给旧正文补标签。item 清理后同 key 重建也必须分配严格更大
+的 revision/epoch，不能复用已确认身份。
+
+caller invocation 成功 completed 后，pending/open item 只把 `presentedRevision` 推进到 `includedRevision`，item
+继续保留但未变化时不再重复注入；terminal/withdrawn 仅在 current revision 仍匹配时 compare-and-clear。若 prompt
+已包含 C removed@rev2，而完成前 C 又被重新加入为 rev3，旧 invocation 只能确认 rev2，不能清掉 rev3。预算裁剪、
+prompt 建成后的新 revision、失败或取消都不确认。
+
+这份 view 是可丢弃的客户端运行时派生状态，不持久化，不改变 source message 或 `dispatchRefs` 的既有语义，也
+不成为第四本账；Queue 仍是 pending truth，History 仍是 actual result truth。它的生命周期天然由“入口追加/更新
+revision → caller 成功观察 terminal/withdrawn revision 后清理 → 新 source 或新 mutation 再追加”闭合。
+
+runtime restart 后不自动重建这份进程内观察集合，也不扫描 History。actual result 仍可从 canonical History
+查询；旧 runtime 独有的 firstAddedBy、Steer 增删说明与 presentedRevision 不保证恢复。每个 caller scope 在下一次自然 invocation
+获得一条固定大小的 `process_start` 说明：当前 observation 只覆盖本进程登记的 dispatch，更早结果仍可按需从
+canonical History 读取。说明不推断旧状态、不创建 Queue work、不清理当前指针；只有实际进入最终 prompt 且
+caller 成功 completed 后才确认，失败或取消后重试，同一 process generation 成功交付后不重复。多 worker/跨节点
+部署若要自动观察跨进程结果，必须另行建立可重建查询或持久交付证据，不能把当前进程缓存升级为第四本账。
+
+## 当前结果
+
+- 持久 `QueueLedgerEntry` 一条 source 一行；`targets[]` 与作者意图只覆盖尚待投递成员，不保存执行／终态回执。
+- 入口不再维护平行的追加、等待或恢复编排；Message＋Queue 原子准入、exact claim、commit、restore 与必要拒收补偿仍保留。
+- 自动追加与新回合共享同目标顺序；准备中的 exact 父执行在 ready 后重新通知 drain。native ACK 只占对应 target，不阻塞无关成员。
+- 读取回执与 provider presentation 不成为 Queue membership 或第二次 admission 条件。
+
+## 迁移
+
+Redis Queue schema v2 在每个 thread 首次访问时原子升级：
+
+- v1 `queued` 与遗留短 `claimed` 行按 `sourceRecordId` 合并为一个 v2 entry，保留最早顺序、pending targets 与逐目标作者意图；
+- v1 `processing/terminal` 不重新入队，避免把已经 admission/终局的工作复活；
+- `order` 与 `messageId → entryId` 索引在同一 CAS 脚本中重建；并发写导致快照变化时重读重试，不能在半迁移状态继续运行。
+
+## 一致性代价
+
+`deliveryStatus` 与队列条目状态分处两地，但 `deliveryStatus` 只有 3 态且**单调**（queued → delivered/canceled），出队时一次写回即可，不需要持续同步。
+
+---
+
+## 身份与兼容读取
+
+新 Queue entry 的 id 由持久 source identity 确定性派生，不为每个 target 分配独立身份。`owner` 使用 user/system 判别 union；消息作者的 `from` 是独立的 user/agent/external/system union，存储 tenant/userId 不冒充作者。
+
+历史 Message 的 `from` 可以缺失；`messageFrom` 在唯一读取边界按 legacy source/userId/catId/origin 推导。新 Message 必须携带 `from`，不为强化类型全量回写历史数据。`queueOwner` 集中处理旧进程内调用形状，持久行仍验证明确 owner。
+
+scheduler source 使用 `{kind:'system', service:'scheduler'}`，存储 userId 与 Queue owner 使用已验证的 trigger owner。各 producer 通过共同 send 提交 envelope；旧 `ConnectorInvokeTrigger` 和 producer 自行推进的调用链已退役。
+
+共同准入保存显式意图或 thread/global/product 默认偏好与 exact parent。相同 ID 重放复用已提交的目标和策略，偏好后改只作用于新消息；原 envelope 不一致仍冲突。Lua/内存转换保持空数组形状，不把无目标数组编码为对象。

 ## Why
 
-operator在 Codex 原生体验中使用 **Steer**：当消息在队列里等待时，点击 Steer 会让“那条排队消息”立刻进入猫的处理流程（而不是只能撤回/重排/再发一条）。
+operator 在 Codex 原生体验中使用 **Steer**：当消息在队列里等待时，点击 Steer 可以把同一条持久消息立即送给一个或多个成员，并逐成员选择“引导当前回复”或“中断当前回复”，而不是只能撤回、重排或再发一条。
 
 ## What
 
-- 在 QueuePanel 的 **queued** 条目上新增 **Steer** 按钮
-- 点击后只有一个 Steer 动作：取消目标猫当前 invocation（如有），并以**同一条持久 Queue 消息**立即启动一次
+- QueuePanel 的 **queued** 条目显示 **Steer** 按钮
+- 弹窗候选取 thread participants、消息路由目标与 Queue fallback 的去重并集；已处理目标可见但禁选
+- 支持多选，并为每个选中成员分别选择“立即发送，引导回复”或“立即发送，中断回复”
+- 历史/恢复 row 的 targetless 绑定与 `targets[]` 增删在同一持久 mutation 完成；普通无 `@` 用户输入已在入队前绑定 target；随后各 target 独立投递和终局
 - 普通重排继续由 drag/move API 独立提供，不再借用 Steer 名称
 
 ## Acceptance Criteria
 
 - [x] AC-A1: 本文档需在本轮迁移后维持模板核心结构（Status/Why/What/Dependencies/Risk/Timeline）。
 - [x] `queued` 条目显示 Steer（`processing` 不显示）
-- [x] Steer 弹窗明确告知“取消当前轮并以同一消息立即重启”，且可取消操作
-- [x] 有猫在跑时先 cancel，再以被 Steer 的 exact Queue entry 启动一次；空闲时直接启动同一 entry
+- [x] Steer 弹窗始终显示“立即发送，引导回复”与“立即发送，中断回复”；静态 client capability 不满足时禁用引导并说明原因，当前活跃快照不参与弹窗能力判定
+- [x] 候选集合包含 participants、路由目标与 exact Queue fallback；默认选中尚待处理的路由/fallback 目标，已处理目标禁选
+- [x] 多目标选择在确认时原子更新同一 source entry 的 pending `targets[]`；每个 target 的 guide/interrupt 动作和终局彼此独立
+- [x] “引导回复”在服务端确认时重读 exact active parent invocation；父 invocation 存在时，`exact_active_turn` 表示当前可见轮次的精确承载；模型读取由独立可选回执证明，`queued_internal_turn` 则追加到同一运行的下一内部轮次；父 invocation 不存在或不能引导时保留普通 Queue 语义且绝不自动 cancel
+- [x] “中断回复”有猫在跑时先 cancel，再以被 Steer 的 exact Queue row 启动；空闲时直接启动同一 row
 - [x] `{ mode: "promote" }` 被 API 拒绝；重排只走独立 move/reorder 交互
 - [x] Steer 不创建 supplement 或第二个 later carrier
-- [x] 具备 API/Web 测试覆盖（至少：权限、409 processing、promote reject、默认 immediate）
+- [x] 具备 API/Web/Redis 测试覆盖（权限、stale/terminal/membership conflict、原子 fan-out、逐成员 mixed strategy、promote reject、默认 immediate）
 
 ## Implementation
 
 ### Backend
 
-- Endpoint: `POST /api/threads/:threadId/queue/:entryId/steer`
-- Body: 空 body 或 `{ "mode": "immediate" }`；其他 mode 返回 400
+- `GET /api/threads/:threadId/queue/:entryId/targets`：将 Queue pending targets 与 History 已投递 refs 联结为逐成员投影
+- `POST /api/threads/:threadId/queue/:entryId/targets`：重读 live truth，跳过已投递成员，并原子 reconcile 同一 source entry 的目标集合与逐成员策略
+- `POST /api/threads/:threadId/queue/:entryId/continue`：把 source entry 的 exact target 引导进当前回复；exact run 已变化时保留为排队等待
+- `POST /api/threads/:threadId/queue/:entryId/steer`：执行单个 target 的中断回复动作
+- `/steer` body 为空或 `{ "mode": "immediate", "targetCatId": "..." }`；其他 mode 返回 400
 - Rules:
   - 404 if entry not found in current user scope
-  - 409 if entry is `processing` (processing steer out-of-scope)
-  - `immediate`: cancels active invocation (same user) and starts processing via QueueProcessor
+  - 409 if another action holds the short claim; a target delivered while the modal was open is skipped idempotently
+  - target mapping rereads History dispatch refs plus current availability/membership before any target action
+  - `continue`: append only to the exact supporting Active Run; otherwise keep normal Queue work
+  - `immediate`: cancel the exact target invocation (same user) and dispatch that target from the source entry via QueueProcessor
 - WS: immediate execution follows normal Queue processing updates; no `steer_promote` action exists
 
 ### Frontend
 
 - `QueuePanel` queued entry row adds **Steer** button
-- Modal offers one explicit action: 取消当前猫，并以同一条消息立即重启
+- Modal lists the deduplicated member projection, permits multi-select, and stores one strategy per selected target
+- Static guide capability comes from the configured Agent Client via the server cat projection; Web must not hard-code it or infer it from recent speech
+- Queue rows do not duplicate capability explanations; the modal owns the selectable capability surface
 
 ### Reorder（F175 扩展）
 
 F175 在 Steer 基础上扩展了用户可控编排能力：
 
 - **Drag & Drop 排序**：QueuePanel 支持拖动排序（`@dnd-kit`），拖拽后通过 `PATCH /queue/reorder` 批量设置 position
-- **Reorder API**：`PATCH /api/threads/:threadId/queue/reorder`，body: `{ positions: [{ entryId, position }] }`
-- **排序语义**：显式 position（用户手动拖动）仅在同 user 内覆盖 `priority`，未手动排序的 entry 仍按 `priority > createdAt`
+- **Reorder API**：`PATCH /api/threads/:threadId/queue/reorder`，body: `{ expectedQueueRevision, orderedVisibleEntryIds }`（RFC #1356 §4.1 `ReorderVisibleEntriesCommand`）。前端提交同一 snapshot 下**完整的 visible row 顺序**；服务端校验 revision 与集合一致后原子写入 `position=0..n-1`，revision/集合/eligibility 任一变化即整批 typed conflict，不做 partial write
+- **排序语义**：唯一 comparator 为 `position presence → position → priority(urgent before normal) → enqueuedAt → id`。隐藏 rows 不被客户端寻址，仍按自身 priority/FIFO 排序
 - **Optimistic UI**：前端立即按 comparator 重排，失败时 rollback
 
 ## Key Decisions
 
-- Steer 不改动消息内容，也不表示 promote / supplement；它只做 cancel + exact-message restart
+- Steer 不改动消息内容，也不表示 promote / supplement；它只更新同一 source Queue Entry 的 pending targets，并对 exact target 做 guide 或 cancel + restart
+- 多目标 initial admission 是 all-or-none；cutover 后 sibling 独立，某 target 启动失败不取消已被其他 target 接受的动作
+- mixed strategy 是逐 target 的 UI 表达，不是 Queue 账本的新状态机；账本只保存一条 source row、pending `targets[]` 与逐目标 author intent
+- 打开弹窗只读；新增 thread member 只在确认时写入。确认时重读 live state：弹窗打开后已投递的目标直接跳过，移出 thread 或不可用的新增目标不准入；旧快照不能复活已投递 target
 - 排序是独立的 Queue 控制面，不属于 Steer
 - `processing` 不提供 Steer：运行中纠偏属于更大能力（需要运行中注入/重路由），本 feature 不扩大范围
 
+## 设计现状（2026-09-02 校准，见 ADR-043）
+
+> **本节记录已落地的 ADR-043 语义。**
+
+中断动作先原子 claim exact target，再请求 cancel 正在运行的 invocation。actual delivery 从 `targets[]` 删除该 target；取消或准入失败时以同一 claim/fence 恢复尚未接管的工作。Queue 不持久化 processing；新的运行 identity 与终局属于 TurnExecution／response lifecycle。
+
+引导动作保存 exact parent 与发送意图；客户端尚在准备时保留工作并由 ready 回调推进，不误判为永久不支持。持久接管后 native ACK 只占对应 target，不阻挡无关成员。
+
+### Interrupt 动作的不变量
+
+对已经完成 target mapping 的单个 interrupt action，唯一应当拦截的 Queue 生命周期场景是“同一 source entry 已被另一个短 claim 占用”→ 409 `ENTRY_PROCESSING`。已经实际投递的 target 由 History `dispatchRef` 识别并幂等跳过，不是整批冲突。
+
+target mapping 自身还必须联结 History actual-dispatch、membership 与 availability；这些是确认时的资格 fence，不是 interrupt claim 的第二套生命周期。其余 interrupt 拒绝只允许是通用鉴权/归属/schema guard、系统固定位置约束，或真实基础设施失败（例如取消 I/O 失败）。旧三段式产生的 `STEER_STATE_CHANGED` / `STEER_RESERVATION_LOST` / `STEER_RESERVATION_PERSIST_FAILED` / `QUEUE_BUSY` / `PRESTART_STATE_CHANGED` 已消失。并发抢先 claim 统一投影为 `ENTRY_PROCESSING`。
+
+新增任何 Steer 拒绝分支前，必须先证明它不是上述两类产物。
+
 ## Risk / Blast Radius
 
-- **状态机复杂度**：立即执行会触发 cancel → 需要确保 queue 不被错误 pause
-- **并发/互斥**：需要保持 QueueProcessor mutex 语义，不允许同 thread 并发执行两条
+- **原子映射**：历史/恢复 targetless binding 与 target-set reconcile 不能留下 ghost/半组 targets
+- **状态机复杂度**：interrupt 会触发 cancel → 需要确保 queue 不被错误 pause；guide 不得暗中升级成 cancel
+- **并发/互斥**：需要保持 QueueProcessor mutex 语义；逐 target 动作可以独立终局，但同一 target 不能 double-start

+本特性把消息形成、持久准入、出队、执行与可见反馈连接起来。详细投递协议见 [RFC](../architecture/message-delivery-handling-handoff-audit.md)，存储与转换决策见 [ADR-043](../decisions/043-queue-durable-single-ledger.md)。
 
-根因：当前架构下 queue send 在 enqueue 阶段就持久化 user message 并做乐观插入，但没有 delivery status 概念。History API 和 ContextAssembler 不区分 queued/delivered/canceled，导致未送达甚至已取消的消息污染聊天历史和猫猫上下文。
+## User Journey
 
-**2026-03-14 原始 invariant**：`undelivered user messages MUST NOT appear in timeline, history API, or prompt context.`
+1. 用户、成员、IM、邮件、插件或通知提交内容、来源、目标、幂等身份与可选发送策略；入口完成自身协议解析和鉴权后调用共同 `send`。
+2. 共同准入解析目标与发送策略，原子提交 source Message 和一条 Queue entry，再通知唯一 drain。未投递的用户／外部输入显示在 Queue Panel。
+3. 排队策略等待目标空闲；引导策略在 exact 当前回复支持追加时进入原回复。客户端尚在准备时保留请求，就绪事件自动推进，不需要用户点击 Stop 解堵。
+4. 每个实际目标拥有固定 response 与因果 `dispatchRef`。同一输入可有多个目标；同一回复也可接收多条输入，双方身份与顺序都保留。
+5. 成员完成、失败或取消后，原回复原位终局，等待消息自然出队。Steer、撤回与 Stop 是明确用户操作；刷新读取同一持久事实。
 
-**2026-07-21 契约演进（F264）**：原句把“operator查看自己已持久化的消息”和“猫获得正文”混成一个
-visibility 开关，已被 F264 的 per-target receipt 契约细分：
+## Unified State Model
 
-- durable queued user message 从 admission 起留在**operator的浏览器时间线**原位，并显示真实 Queue receipt；
-- 同一消息在 exact delivery 前仍不得进入猫的 callback/thread-context/prompt/pending-mentions；
-- canceled 消息同时从 live 时间线与 F5 history 消失；
-- `deliveryStatus` 继续表示 cat delivery，不再兼任 owner timeline publication。
+旧版 A2A 前端的 develop_base 对照、已保留能力与 classic／v2 分阶段补齐，见 [前端迁移清单](../plans/2026-10-13-f117-classic-a2a-frontend-parity.md)。该清单不改变下面的单一 Queue／History 契约。
 
-operator experience：
-> "前端不应该显示你们真正没有收到的消息，对吧？"
-> "当我发了一个正在队列的消息的时候，我的用户气泡这里先不显示，等到你们真的收到这个消息的那一刻，再在正确的地方插入这个气泡"
+| 事实 | Owner |
+|---|---|
+| 内容、作者身份、可见性、原始消息身份 | MessageStore source record |
+| 尚待投递的目标、顺序、策略与短 claim | 一条 source Queue entry |
+| 实际 source×target 投递及 optional read receipt | source `dispatchRefs[]` |
+| 被 exact 执行接收的输入、正文与终局 | 固定 response lifecycle 与 TurnExecution |
+| action／wait 的责任、权限与 generation | 各自 structured owner |
+| caller 尚需观察的 outbound 变化 | 可丢弃的 process-local view；不裁决执行 |
 
-## 已确认的 Bug 现象（operator实测 2026-03-14）
+Queue 只有 pending 工作，不保存 processing／terminal／seen／handled 的第二套账。实际投递删除对应 pending target，最后一个 target 离开后删除 entry；History 保留结果。新消息重试事项不复活旧终局。
 
-### Bug 1: 队列消息提前显示气泡
-- **复现**：猫猫正在回复中 → 用户发消息（自动进队列）→ 消息还在"排队中"面板 → 聊天流里气泡已经出现
-- **期望**：队列面板显示即可，聊天气泡等到消息真正"送达"（dequeue 执行）时才插入
-- **截图**：同一条消息同时出现在聊天气泡和排队面板（`1773488348921-03899885.png`）
+## What
 
-### Bug 2: 取消后消息仍在气泡 + 仍进入猫猫上下文
-- **复现**：用户在队列面板按 X 取消消息 → 气泡仍然留在聊天流 → 猫猫下次回复时 prompt context 里有这条已取消的消息
-- **期望**：取消后气泡消失，猫猫永远不应该"看到"这条消息
-- **实测证据**：operator发送 `嘿嘿大猫猫喵` → 取消 → 猫猫对话上下文中仍出现该消息
+### Phase A: deliveryStatus 与持久准入
 
-### Bug 3a: queued 用户 @mention 提前进入 pending-mentions（F117 scope）
-- **复现**：用户发带 @gpt52 的消息 → 消息进入队列（排队中）→ `pending-mentions` 已包含该条目
-- **期望**：queued/canceled 的用户 @mention 不应出现在 `pending-mentions`；delivered 后才进入
-- **根因**：mention inbox 读取时只看 `msg.mentions`，不看 `deliveryStatus`
+一条 source 对应一条 Queue entry；多目标保存在 `targets[]` 中。source Message 与初始完整 target set 原子写入，不允许“正文已存、没有 Queue work”的半提交。来源身份与存储 owner 分开，所有新消息携带结构化 `from`。
 
-### Bug 3b: `cat_cafe_post_message` 的 @mention 路由异常（F117 out of scope）
-- **复现**：猫猫用 `cat_cafe_post_message` 发带 `@gpt52` 的消息 → Maine Coon session 未收到
-- **截图**：`1773488607773-f4b34f0a.png`
-- **不属于 F117**：`post_message` 走 callback 路由（`callbacks.ts` → `messageStore.append` + `enqueueA2ATargets`），不经过前端 queue send，不依赖 delivery lifecycle
-- **处置**：单开 callback @mention 路由 bug，F117 仅标记 `related`
+用户／外部 source 在实际投递前不取得共同 History membership；第一次实际投递复用原 identity 发布，后续目标追加同一 source 的 refs。Agent `post_message` 已是 History message，Queue 只保存引用；completed final 原位更新既有 response，下一跳引用该 response，不复制正文。
 
-### 根因链路（Maine Coon + Ragdoll调查确认）
-1. `useSendMessage.ts:95-100` — 无条件乐观插入，不区分 queue/immediate
-2. `messages.ts:249` — enqueue 阶段就持久化 user message，无 delivery status 标记
-3. `messages.ts:700` — History API 不过滤 delivery status
-4. `ContextAssembler.ts:99` — 不过滤 delivery status，未送达/已取消消息直接进 prompt
-5. `queue.ts:99,249` — withdraw/clear 只删 queue entry，不处理已持久化的 message
+### Phase B: 前端投影
 
-## What
+Queue Panel 展示 pending 工作，聊天面板展示 History 与固定 response。live、刷新与重连消费同一 Message lifecycle；时间线位置、回执与引用不能从日志、正文相似度或本地偏好推断。
+
+### Phase C: Dispatch 可视化
+
+源消息的成员头像来自实际 `dispatchRefs`，导航到 exact response；pending target 不制造假 processing 头像。bodyless processing response 承载头像和 tip，正文到达后原位升级，不另建等待气泡。失败保留 partial body 与完整诊断，只呈现一份结果。
+
+Append 的 `inputMessageIds` 表示该 response 已接管输入，不能当作模型已读证明。支持读取回执的 adapter 在 `dispatchRef.inputRead` 上保存 `pending` 或 `{ status: 'read', at }`；没有回执能力时不伪造已读。可选读取证据不决定 Queue membership、输入归属或业务终局，缺失时不自动重派。
+
+### Phase D: Queue 内核
+
+所有来源进入同一 ledger 与 `requestDrain`。唯一 comparator 为 position、urgent/normal、FIFO、稳定 id；source category 不暗中改变顺序或能力判断。
+
+普通 drain 按 comparator 扫描，后来的自动追加和新回合都不能越过同目标的旧等待项。等待项只阻挡与它有共同目标的工作，不阻挡无关成员。普通新回合领取一条 source 的本轮完整 pending target set，再并发提交独立 receiver／ref；显式 Steer 或 exact unread adoption 可领取 singleton target。不同 source 不合并正文或身份。
+
+每 target 的 durable handoff 后，其 native ACK 只占该 target；不阻塞无关 target 或让 HTTP 等待整条回复。取消 fence、重试时刻、owner、可见性与 exact parent 仍在执行时复验。`requestDrain` 的 dirty bit 保留并发信号；入队、handoff、客户端就绪、终局、重排及 owner evidence 变化均可推进同一 owner。
+
+### Phase E: 用户操作
+
+- 默认策略为 `next_work`；`continue_current` 是可选的非中断引导。全局、thread 与单次选择使用同一契约。
+- Steer 读取当前 pending／dispatched join；确认时重读资格和 exact run，逐成员选择引导或中断。已投递目标不被旧快照复活。
+- 引导在 exact 支持的当前回复追加；无当前父执行或不支持时保留普通 Queue 工作，不暗中中断。准备中的父执行保留引导意图，ready 回调重新通知 drain。
+- 中断先取得精确 claim，再取消该目标执行；失败恢复未投递工作，不回滚已接收的 sibling。
+- Stop 控制 exact 执行。没有可控活候选时按既有 reconciliation 收敛真实运行状态，不删除消息、历史或其他目标的运行。
+- 已出队后的跟进请求可能返回 `ENTRY_NOT_FOUND`；前端刷新 canonical snapshot 收敛，不重复执行，也不把完成后的竞争当作新的业务失败。
+
+### Phase F: Carrier 与副作用边界
+
+成员顶层 canonical `carrier` 决定接入方式。旧 transport 兼容只在配置边界读取，不在运行路径按全局开关改派 carrier。一个 carrier 的故障不能静默换成另一个。
+
+`activeInvocationGuidance`、`deliverySemantics` 与 `inputReadReceipt` 分别表示能否引导、承载精度和读取证据。引导能力不等于模型已读；`queued_internal_turn` 不冒充 `exact_active_turn`。MCP/callback send 是发送原语，不在出口检查 inbox、HELD 或注入强制读取教学。
 
-### Phase A: deliveryStatus 字段 + 后端收口
+### Phase G: Managed hold 与 structured continuation
 
-1. Message 模型新增 `deliveryStatus?: 'queued' | 'delivered' | 'canceled'`（老数据缺省 `delivered` 兼容）
-2. enqueue 时 message 持久化带 `deliveryStatus: 'queued'`
-3. MessageStore 默认读只返回 `delivered`（或无 deliveryStatus 的历史消息）；F264 后 owner-facing
-   `GET /api/messages` 显式 opt-in durable queued user publication，cat cognition readers 不 opt-in
-4. ContextAssembler 只组装 `delivered` 消息
-5. Mention surfaces（`pending-mentions` 等）只返回 `delivered` 消息的 @mention
-6. QueueProcessor dequeue 执行时：将 message 标为 `delivered`，扩展 `messages_delivered` 事件携带完整 user message payload
-6. withdraw 单条：同步将 message 标 `canceled`，发 `message_deleted` 给前端
-7. clear 队列：批量标 `canceled`，发批量 `message_deleted`
+hold 命令结果保存在原 task；需要唤醒时提交幂等的 source/Queue work，并由 response 表达本次处理。结果、责任与 message delivery 不复制到 Ball disposition 或 Queue receipt。
 
-### Phase B: 前端适配
+action／wait／callback 的 private input 保留 exact owner、principal、generation、predicate 与 expiry；共同 Queue 运输这些约束，不签发权限，也不把它们变成普通 fallback。
 
-> 以下是 2026-03-14 的历史交付。F264 于 2026-07-21 仅 supersede “queued user bubble 何时对operator
-> 可见”：显式 queue send 在 202 成功并拿到 durable message id 后插入；smart-default queued 保留并
-> reconcile optimistic bubble。取消与 cat-context 隔离仍完全沿用 F117。
+### Phase H: Caller outbound view 与失败回流
 
-1. queue send 时**不做乐观插入**到主时间线（QueuePanel 仍通过 `queue_updated` 展示）
-2. 收到扩展版 `messages_delivered` 事件时，将 user message 插入主时间线
-3. 收到 `message_deleted` 时，从 store 中移除对应 message
-4. F5 hydration 路径：history API 已过滤，无需额外处理
+caller 的运行时观察以 exact source×target 为单位，记录已提交的选择变化与呈现 revision。实际 pending、dispatch、delivery failure 与 terminal 都从 Queue／History 反查。成功呈现 terminal／withdrawn revision 后 compare-and-clear，期间新增 revision 不被旧 invocation 清掉。
+
+正常 completed／canceled／interrupted 不自动重启 caller。exact A2A failed 与原失败 response 原子提交幂等 `a2a_failure` message-ref control wake，唤醒 exact caller 读取原结果；不复制失败正文，不登记新的业务 handoff，不递归 fail-back。重启不自动重建旧进程的观察集合；历史结果仍可查询。
+
+### Phase I: 共同 send 与目标、策略快照
+
+入口只提交 envelope；普通消息的目标解析、默认策略解析、持久化和 drain 通知属于共同准入。新增一种普通来源不需要新增调度分支。
+
+普通正文只把匹配现有成员的 mention 当作目标；未匹配的 `@` 原样留在正文，不新增 warning、错误卡或等待状态。没有有效可用目标时使用既有 resolver：最近 completed 回复者，再到配置 fallback；普通公开目标不可用时允许 fallback。显式协议 ID 的身份校验不适用正文忽略规则。
+
+A2A 的行首路由或指定 ID 是 exact 目标：目标不存在／不可执行走已有 delivery failure 回报，不改投默认成员。whisper 与其他授权绑定输入也保持精确收件人；公开 fallback 不扩大其可见性。排队后和追加前都复验 source/receiver 的权限。
+
+策略在共同准入、持久入队前解析：单次显式意图优先，否则 thread override → global → product default。按每个实际目标保存意图与 exact parent；来源不参与默认选择，不增加 per-cat 设置。
+
+同幂等 ID 重放复用首次赢得提交的目标与策略，包括已退役 Queue row 的持久接纳事实。后续偏好变化作用于新消息；同 ID 不同 envelope 保留冲突校验。不同 ID 同正文是不同消息，不按正文或时间窗口去重。
+
+### Phase J: 执行活性、启动与超时
+
+durable invocation／child／response 是执行事实，tracker／process owner 是活性见证。草稿不作为 TTL 或更新时间意义上的运行判据。重启保留数据并收敛旧运行；不重建 provider client 或自动重放已经接管的输入。
+
+每成员的无输出超时使用 `CLI_TIMEOUT_MS`，默认 `0`（禁用）。启用时 text／tool／thinking 等真实输出刷新计时；仍占 CPU 的进程可有界顺延至两倍。触发走 exact Stop／failed timeout 终局；不取消无关 sibling。启动前无首帧的既有重试与运行后无输出超时分开。
+
+### Phase K: SDK 结果身份
+
+provider 自发 task/channel/peer 通知的 result 不能在缺少对应输入身份时核销用户输入。支持权威压缩的 SDK 通过实际 PreCompact/seal 接线证明边界；不能从正文或单个不完整事件猜测压缩完成。
+
+### Phase M: 追加、读取与执行归属
+
+追加先持久绑定 source、exact response 和输入身份，再将该 target 从 Queue 退役并交给 dispatcher。读回执独立单调更新。客户端拒收按 existing compensation 恢复尚未接管的目标；成功接管后，缺少模型读取证据不能成为第二次 admission。

 ## Risk
 
-| 风险 | 缓解 |
-|------|------|
-| 老数据无 deliveryStatus 字段，查询可能误伤 | 缺省按 `delivered` 兼容，过滤条件 `WHERE deliveryStatus IS NULL OR deliveryStatus='delivered'` |
-| `messages_delivered` payload 变更影响现有消费者 | 扩展而非重构，新增 `userMessage` 字段，现有字段不变 |
-| withdraw/clear 新增 `message_deleted` 事件可能与现有删除逻辑冲突 | 复用现有 `message_deleted` handler，确认幂等 |
+跨 Message／Queue cutover、native readiness 和真实存储转换必须联合验证；局部 mock 通过不能替代产品装配。新增入口不得保留平行调度。可选回执不能变成 admission 或责任门禁。公开 fallback 必须守住私密收件人边界。

-| KD-3 | 修完后走全量 sync 而非 hotfix | 有多个已完成 F 待同步，hotfix 增加后续同步难度（operator决定）| 2026-03-14 |
-| KD-4 | Bug 3 拆分：queued @mention 泄漏 in scope / post_message callback 路由 out of scope | post_message 走 callback 路由不经 queue，硬塞进 F117 会混 scope（Maine Coon Design Gate 提出）| 2026-03-14 |
-| KD-5 | owner timeline publication 与 cat delivery 分成两个 typed read option | F264 receipt 必须让operator持续看见原消息；复用全局 `isTimelinePublished` 会把未投递正文泄给猫 | 2026-07-21 |
+实现已进入 fork；运行验收与持续观察属于发布状态，不能由这份规范自行宣告完成。上游 #1398 的 Draft／review／merge 状态以 GitHub 和维护者决策为准。

+- Queue 是待投递工作的唯一持久 owner；普通 callback send 不检查 HELD/inbox，不强迫先读再发，也不创建 Queue seen/handled 或 receipt/reminder 的第二本账。
+- supplement offer/claim/decline、output-commit closure、出口 freshness scan 与 B3/B4 自动 re-invoke 已退役。下文这些 Phase 的设计、过程和勾选项仅供历史阅读，不能作为当前 API、设置或调度契约。
+- 公开发布保留原子 `appendAndObservePriorFrontier`，`extra.freshness` 只携带 `priorFrontierMessageId` 供时间线排序；旧 kind 不恢复门禁或补充载体。
+- provider-native freshness 与载体精度独立保留，读取面见 `freshness-unseen-source.ts`。`activeInvocationGuidance`、`deliverySemantics` 与可选读取回执各自描述能力，不能互相推断。
+- 新消息经共同 send 保存目标、策略并通知 drain；等待、非中断追加和就绪推进使用 [F117](F117-message-delivery-lifecycle.md) 与 [ADR-043](../decisions/043-queue-durable-single-ledger.md) 的同一链路。

+# F117：develop_base 的 A2A 前端调整与 #1398 旧版补齐清单
+
+本清单先解释已经存在的能力，再定义当前缺口。**当前只补齐 classic 旧前端；旧版体验确认后，再调整 v2 新前端。** develop_base 是旧版布局与视觉参照，不是把旧实现整文件覆盖回最新 main 的来源。
+
+## 1. 比较坐标与证据范围
+
+| 对象 | 精确提交 | 用途 |
+|---|---|---|
+| 原公开共同基线（#1577） | `3e70e1d6805be24672e8f841861f180d20b184c2` | 识别 develop_base 的后续改动；也是 develop_base 与 #1584 main 的 merge-base |
+| 运行目录 develop_base，只读 | `7adb57dfa6cfa3465e3a009a67b48f0cc44d23c6` | 旧前端实际代码与已接受的 A2A 交互参照 |
+| #1584 合入后的 main | `0fc7e37473395a080a0463fac11c22310391ec42` | 当前 #1398 重建基线 |
+| 已审、已发布的 #1398 | `6bce64e77d04ac1a8224475439a6a7d039844dab` | 本清单审计对象，尚未包含本轮 UI 修复 |
+
+实际 read-only 对照目录分别为 `cat-cafe-develop-base` 与 `cat-cafe-1398-merged-baseline`。两者属于不同 Git 仓库，比较前在候选仓库只读导入了 develop_base 的精确 commit 对象；没有更改运行目录、配置或进程。
+
+develop_base 的相关历史包含 fork #217（原 F117 接入）、#218（目标引导能力与重启回流）、#219（跨 thread 与 Codex 已读）、#220（能力提示、错误呈现与终态交接）、#224（共同投递与 Redis／preparing-run 修正）。#222／#223 和对应 revert 不是另一套需要恢复的前端机制。
+
+范围是输入／策略、Queue／Steer、source／response、追加输入／回执、执行状态与颜色等 A2A 用户路径及其定向测试。原共同基线到 develop_base 有 449 个 Web `src` 路径变更；这个数量包含混入的其他前端工作，**不等于 449 项 A2A 改动**。本清单不是全部 Web diff 的逐文件搬运清单。
+
+原始需求位于 `thread_msr51149hym0i79f`：
+
+- `0001789632701627-000557-7561512a`：发送策略只保留持久偏好，不再加“仅这一次／恢复继承／入队说明”。
+- `0001789630806333-000545-adc349e0`：Steer 默认策略与目标引导能力的边界；当前运行状态不另造偏好。
+- `0001791788596790-000350-bd2cd477`、`0001791790207880-000395-0d216bfe`：A/B 姓名语义不同，只统一状态与发生时间，B 侧保留正文。
+- `0001791856574961-001444-f2da7ef0`：菜单、气泡标签、点击展开与来源圆点的实测问题。
+- `0001791856653691-001448-2bb44573`：页头重复执行提示。
+- `0001791856688634-001449-5ea6f740`、`0001791856707628-001450-7cee477b`、`0001791856981952-001457-5ace39c0`：以 develop_base 旧版为参照，先成文、先修旧版，再处理新版。
+
+记忆检索仅用于定位旧决策；一次 hybrid thread 检索降级为 lexical，不能据其有限结果宣称完整历史。结论以精确 Git 版本、组件源码、已读原话和本轮截图为准。
+
+## 2. 两种前端展示，共用一套 A2A 事实
+
+两种展示位于同一个 `packages/web`，不是两套独立的 A2A 后端或状态账本。`AppShell.tsx`／`shell/shell-presentation.ts` 通过 classic／v2 选择展示；`ChatContainer`、`ChatInput`、`ChatMessage` 等有共享组件与展示分支。
+
+classic 应对齐 develop_base 的旧版空间关系、菜单布局与既有操作。v2 保留 #1584 的导航、版式、主题 token 与阅读位置能力，本阶段不重新设计它。共享组件可以增加明确的 presentation 分支；数据消费、权限和投递事实仍只有一个契约。
+
+数据契约以 [F117 主文档](../features/F117-message-delivery-lifecycle.md) 为准：Queue 是尚待投递工作，History 是已发生事实；投递、执行归属、原生已读证据互不代替。
+
+### 后端能力合并边界（operator 再确认）
+
+classic／v2 是展示分支；旧版保留 develop_base 的布局与既有操作，随后再补新版展示。共享组件应围绕 presentation 分支承载这两种布局，不让 main 的新版摆放规则覆盖旧版，也不建立两份业务状态。后端继续以 #1398 的共同 send、单一 Queue、History 和精确原生读取证据为准；同步 main 是迁入新增能力的消费者，不是换回旧 A2A 状态机。
+
+| 已核对的业务能力族 | #1398 的承接边界 | 已有源码／验证锚点 |
+|---|---|---|
+| 用户、成员、外部入口与 SDK 输入 | 共同准入，冻结 target／intent／audience；相同 ID 重放保持原身份 | `InvocationQueue.send`、`PersistedQueueDelivery`；`a2a-1577-sdk-input-seam`、producer-category、message-scope |
+| 修改请求、工作 producer、调度与部署通知 | 原业务 authority 保留，投递通过同一适配器；队列退休后消费持久事实 | modification-source、work-producer、deployment-publication、scheduler、refusal seams |
+| Collective 与插件来源 | structured source 与精确 caller／owner／thread 边界；不以 transport 标签代替授权 | collective-reconsideration、hold-consumer、action-history seams |
+| 私密媒体回流及追加 | 复用持久 TurnExecution 见证，public input／reply／causal 不挂私密 ID，内部读取与结算保留 | 私密 witness／callback／Append／store reopen／nonrecipient play 回归与独立复核 |
+| 历史、上下文、全文 drill、搜索与 Live inbox | 从持久消息与独立读取回执投影；执行归属／完成不冒充已读 | document、message-drill、thread-context、live-inbox、observational-projection seams |
+
+以上是对 main 消费者和 #1398 既有职责的接线核对，不是宣称整个 main 的所有功能均已真实体验，也不表示表中每项都是 main 新增。私密执行见证是媒体消费者迁入共同执行记录时的接线缺口；Append 公开引用过滤和 terminal settlement 本来就是 #1398 的职责，实际私密验收揭示了自身实现遗漏，已分别复用共同投影与现有内部精确绑定修正。这两项不是 main 特有的新能力，不新增投递机制、隐私账本或补偿层。#1587 只有 Web 变更，本次头部／工具栏修复也不改 API/shared/MCP。旧原生记录保持各自 SHA；Claude、真实媒体生成、最终组合运行、历史／混合版本、rollback／off-mode 与 operator／soak 继续按版本报告未验范围。
+
+## 3. develop_base 已做的调整，以及 #1398 的保留情况
+
+以下路径均相对仓库根目录。表中的“已保留”是代码对照结论，不是本轮完整 UI 体验通过结论。
+
+| 用户路径／能力 | develop_base 的调整 | #1398 当前情况与处置 | 代码锚点 |
+|---|---|---|---|
+| 输入入口 | “+”菜单承载引用、附件、发送策略、悄悄话、游戏；策略作为普通菜单项 | 能力保留，classic 菜单布局和浮层样式有差异，需补齐 | `ChatInputAddMenu.tsx`、`ChatInput.tsx` |
+| 持久发送偏好 | “排队等待／引导当前回复”；“本 Thread／全局默认”两层 | 已保留；不搬回“仅这一次／恢复继承”或重复说明 | `MessageDispositionSelector.tsx`、`useMessageDispositionPreference.ts` |
+| 引导能力 | 输入框根据正在工作的成员及其 `guideReply` 能力提示可引导目标 | 已保留能力判断；仅调整 old shell 展示，不新增前端投递决策 | `ChatInput.tsx`、`message-disposition-presentation.ts` |
+| Pending 与 History | 未投递用户／外部输入只在 Queue；实际投递后显示原消息与固定 response | 已保留新契约；不得恢复队列、inbox、乐观消息的第二份业务状态 | `QueuePanel.tsx`、`chatStore.ts`、`message-timeline.ts` |
+| Queue 操作 | 撤回、排序、逐目标 Steer；等待原因不借用无关成员的活跃状态 | 已保留；由共同服务端投递／资格约束，刷新消费 canonical snapshot | `QueuePanel.tsx`、`QueueSteerDialog.tsx`、`SteerQueuedEntryModal.tsx` |
+| source 身份 | 用户、成员、外部来源按结构化 `from` 显示姓名／头像；transport label 不充当作者授权 | 已保留；主题显示只改颜色角色，不改 actor 身份 | `resolve-sender.ts`、`SenderAvatar.tsx`、`ChatMessage.tsx` |
+| source 下的成员头像 | 真实 `dispatchRefs` 导航到 exact response；pending 不制造 processing 头像 | 已保留；失败、终态、目标匹配仍从现有生命周期投影 | `MessageDispatchAvatars.tsx` |
+| 首条／追加归属 | 收件成员的固定 response 接收首条和追加输入；空正文 processing 行后续原位升级 | 已保留；不增等待气泡、重复完成消息或“已接管即已读”状态 | `ChatMessage.tsx`、`PendingMemberBubble.tsx` |
+| 追加输入列表 | response 下方显示来源、正文摘要、独立“跳到原文”；长文原位展开，较多条目可展开列表 | 已迁入，已有正文／列表展开逻辑；需复验实际测量和点击，修正来源主题圆点 | `AppendedInputReceipts.tsx`、`useMeasuredOverflow.ts` |
+| 投递／读取提示 | 读取 exact source × target × response 的回执；读取时间来自 native receipt | #1398 已进一步统一双方状态与时间，首条 native read 和私密边界也已修复；不要覆盖成旧文案或旧已读推断 | `dispatch-receipt-display.ts`、`MessageDispatchAvatars.tsx`、`AppendedInputReceipts.tsx` |
+| 引用来源标签 | 气泡顶部 ReplyPill 显示来源头像、姓名、摘要，点击跳回原消息 | 跳转仍保留；截断标签点击展开是本轮新补齐要求，不能误写成 develop_base 已有行为 | `ReplyPill.tsx`、`focusLineageMessage.ts` |
+| 执行状态与 Stop | 输入框上方执行条显示成员、工作类型、计时及 exact 取消动作；ChatContainer 不再挂载页头 ThinkingIndicator | 执行条保留，但候选又挂回了页头提示，需恢复既有去重；不丢异常提示与取消动作 | `ThreadExecutionBar.tsx`、`thread-chat/ThreadExecutionLayer.tsx`、`ThinkingIndicator.tsx`、`ChatContainer.tsx` |
+| 失败与终态 | partial body 与诊断属于原 response；空 Queue 不是另一个全局“调用失败”状态 | 保持 #1398 的统一错误／终态呈现；局部错误不搬成整条 thread 的兜底状态 | `ChatMessage.tsx`、`CliDiagnosticsPanel.tsx`、`QueuePanel.tsx` |
+| 多 thread／刷新 | source／response 引用、Queue、活动执行按 thread 取权威快照；刷新不重派历史输入 | 保持共享 data path；classic 和 v2 可以有不同布局，不能各自重建运行事实 | `useThreadMessages`／`useThreadLiveness`、`activeExecutionStore.ts`、`thread-chat` |
+
+### 双方 tooltip 的已定边界
+
+| 状态 | A 侧（source 下的接收者） | B 侧（response 下的来源） |
+|---|---|---|
+| 已投递 | `已投递 B · 时间`，不加正文 | `已收到 A · 时间`，保留 A 的正文 |
+| 已读 | `已读 B · 时间`，不加正文 | `已读 A · 时间`，保留 A 的正文 |
+
+同一条 source×target dispatch 的两侧取同一份状态、同一投递／读取发生时间。姓名分别表示接收者与发送者；不能为了共用组件统一成同一个姓名。首条消息也仅在实际 native 读取事件发生后变成已读；启动、ready、ACK、接管和终态都不是读取证明。
+
+## 4. 本轮旧前端缺口与补齐方式
+
+### C1：输入框“+”菜单
+
+**实际差异**：develop_base 使用旧版圆角纸面菜单，顺序为引用 → 附件 → 发送策略 → 悄悄话 → 游戏，策略标题为“发送策略”、副标题显示当前选择。候选把策略移到顶部、增加“添加”分区，并让 classic 也使用 `ComposerPopover` 的 v2 shell token。
+
+`--shell-paper`／`--shell-hairline-strong` 的展示作用域是 v2。classic 不应引用尚未定义的 v2 颜色，造成透明／默认黑色边框等错误。
+
+**改法**：保留 portal 定位、外点关闭、ESC 和焦点处理；给 classic 使用旧版 cafe surface、圆角、阴影与原顺序。v2 保留当前菜单结构和 token。策略仍消费同一个持久偏好 controller。
+
+**验收**：classic 与 develop_base 对照；五个入口仍可用；策略切换作用域、保存失败、键盘返回／关闭正常；窄屏菜单不越界。v2 抽样确认布局没被旧版修复改写。
+
+### C2：气泡顶部来源标签的样式与点击
+
+**实际差异／边界**：`ReplyPill` 当前只点击跳回原文，没有截断内容的展开操作；这在两个比较版本中都是现状。故“点击展开”是新的体验要求，不是已经迁入或仅因 rebase 丢失的能力。下方 `AppendedInputReceipts` 则已经有长文原位展开，需要独立复验，不能把两处控件混为一个。
+
+**改法**：classic 收起标签对齐来源的主题色和旧版大小；截断摘要可点击展开／收起，展开内容独占下一行、左对齐并使用正文预览字号，避免挤压作者和时间。跳原文保留为独立动作。沿用真实 overflow 规则，短内容不制造空展开。v2 的既有来源标签与阅读动作在本阶段不重新设计。
+
+**验收**：长／短／已删除来源，展开后全文可读且能收起，“跳到原文”定位 exact source；键盘能操作，不嵌套 button，不改变原消息或回执。
+
+服务端 `replyPreview.content` 是短摘要，不能因控件变大就称为全文。展开态只从当前已授权 timeline 的唯一 exact parent 取正文；删除、撤回、重复绑定或其他 thread 的全局 store 不提供正文。原文尚未加载时只保留现有摘要与跳转，不借 transport 或调用者 ID 获得额外读取权限。v2 继续使用原摘要与直接跳转。
+
+### C2b：作者行与消息操作条的完整旧版布局
+
+operator 后续的两张实际截图指出 C1–C4 之外的遗漏：来源应在“轨迹”前；右侧三角是朗读控件，应位于消息操作条内，不能误认成来源展开。真实 develop_base `7adb57df` 的常用操作顺序为朗读 → 复制 ID → 引用 → 多选 → 分支 → 删除。
+
+**改法**：仅 classic 作者行将来源排在轨迹前，将朗读交回现有 MessageActions 与同一 TTS singleton；常用条恢复以上顺序和分支图标。保留 main 新增的“更多”能力与原生轨迹入口，classic 的重复轨迹操作放在“更多”菜单内。v2 的 action overlay、nameplate、轨迹入口与生命周期事实不改。展开来源继续独占下一行，不挤压作者时间；不是整文件回滚到旧版。
+
+**验收**：使用完整 ChatMessage + MessageActions 的组合验证头部顺序、TTS 的准确消息 ID／正文／成员、复制、引用、多选、分支、删除的排列，以及窄屏操作 sheet、更多轨迹和 v2 overlay。实际旧版页面须包含用户反馈的普通短来源消息，不只用长摘要证明展开。窄屏 sheet 的标题与操作行必须在正常文档流中上下排列，不复用作者行的绝对定位；常用按钮在较窄宽度换行，朗读及每个命中区域均不得被标题覆盖。迁移分析／代码回归不替代 operator 的实际体验确认。
+
+### C3：追加消息圆点的来源主题色
+
+**已查事实**：追加行目前传递 `resolveMessageSender(...).color` 的原始配置色。经典消息导航和执行条已有 source/member 的 CSS theme token。主题调节后的颜色可能不同于原始 hex；用户截图中 co-creator 的追加圆点与其显示主题色不同。
+
+**改法**：classic 的人类来源用 `--color-cocreator-primary`，已知成员用其 `--color-{catId}-primary`；未知／外部来源保留其可靠来源色。颜色只表达是谁，不表达执行 target、运行状态或权限。不要取 response 接收者的颜色，不修改全部 sender resolver 的身份含义。
+
+**验收**：人类 A → 成员 B、成员 A → 成员 B、未知来源；圆点随 A 的主题变化，不随 B 变化；刷新、明暗色一致；投递／已读与 pulse 继续由 exact receipt 决定。
+
+### C4：页头重复的执行提示
+
+**已查事实**：develop_base 的 `ThinkingIndicator.tsx` 文件还在，但其 `ChatContainer` 已不再挂载它；输入框上方执行条由 `ThreadExecutionLayer` 承载。候选在合入 main 的展示路径后又挂回了 ThinkingIndicator，导致截图中的“成员回复中 · thread · 实时回合”重复出现。v2 的该组件当前直接返回 null。
+
+**改法**：恢复 develop_base 的 ChatContainer 挂载关系，保留输入框上方统一执行条和 Stop。不要因去掉本处重复挂载而全局删除 ThinkingIndicator 或其他布局仍需要的 timeout、silent／stall、诊断。检查异常信息仍在现有入口可达，不另建一个前端 `isRunning` 推断源。
+
+**验收**：空闲无执行提示；普通运行只有一个主要状态位置；Stop 仍准确；异常／状态快照读取失败仍能获知真实限制；跨 thread 切换不借用别的 thread 的状态。
+
+## 5. 已由 #1398 覆盖、不得借样式迁移恢复的内容
+
+- 共同 send、持久原子准入和单一 Queue 的约束保留；不恢复 provisional admission、custody、rollback 或第二套 inbox／receipt 账本。
+- pending Queue row 退休不意味着消息结果丢失。刷新／同 ID 重试读取持久事实；不要求已读之后 Queue row 仍在。
+- 公开 response 不挂私密 source／return ID；内部 TurnExecution 与授权 owner 实录保留。修颜色、标签和展开时不得顺手把私密内容补进公开 receipt 列表。
+- 不为“启动／收到／完成”增加新的已读状态；不新增读后重启拒绝或替换证明。
+- 不恢复已删除的“仅这一次／恢复继承／入队说明”，不把恢复 UI 样式误变成恢复旧选择链。
+- `ThinkingIndicator` 的普通重复提示不能算必须恢复的旧版特性；它是本轮应继续删减的展示冗余。
+
+## 6. 实施顺序与验证文件
+
+1. 用本清单核旧版路径和定向断言；实现 C1–C4 的 classic 分支，不改变后端。
+2. 完成真实旧版操作：开菜单 → 选择／保存策略 → 发送／排队 → Steer／追加 → 点击长摘要与跳原文 → 查看同一回执 → Stop → 刷新。至少覆盖窄屏、明暗色和一个错误状态。
+3. 共享组件变更抽样 v2，证明本阶段没有把新版换成旧版布局；不要求在本阶段重新设计 v2。
+4. 冻结同一 worktree 后继、定向测试与真实页面证据后一次性交独立复核，更新原 #1398；再交 operator 体验旧版。
+5. operator 确认旧版基础体验后，按其后续授权同步最新 main、重建 develop_base 并创建纳入 #1398 全部改动的 fork PR；随后另行处理 v2 的 A2A 展示。
+
+定向测试入口（按改动选，不为文档跑全仓）：
+
+- `chat-input-add-menu.test.tsx`、`chat-input-message-disposition.test.ts`：菜单与偏好。
+- `ReplyPill.test.tsx`、`appended-input-receipts-render.test.tsx`：来源标签／正文展开与独立跳转。
+- `1398-sender-identity.test.tsx`、`message-dispatch-avatars.test.tsx`、`delivery-response-ownership.test.tsx`：来源、回执、exact 归属。
+- `thinking-indicator-v2.test.tsx` 与执行条／Queue 的相关测试：只去重展示，保留真实状态与操作。
+
+组件级浏览器证明入口为 `packages/web/test/browser/classic-a2a-parity.test.mjs`。测试要求显式提供 `CLASSIC_A2A_PLAYWRIGHT_MODULE`（已安装的 Playwright ESM 模块）；需要复用本机浏览器时可提供 `PLAYWRIGHT_CHROMIUM_EXECUTABLE_PATH`。它拦截传输并验证真实组件与 CSS，不等于真实 native／后端验收，不依赖已退役的 `ppt-forge` 路径。
+
+本文件是迁移分析与待实施清单，不是上述修复已完成的验收报告。冻结 #1398 的后端／私密边界绿灯、旧版基础体验和长期验收是不同证据，不能互相替代。

+ * F194 → F117 KD-23: Invocation liveness read model.
  *
- * Read-only helper that answers "which invocations are live for (threadId, userId)?"
- * by reconciling four independent stores with non-equivalent semantics:
+ * Answers "which members are processing for (threadId, userId)?" without reading any timestamp.
+ * A member is processing when its InvocationRecord is running and someone verifiably runs its turn:
  *
- * - InvocationTracker  → per-process control plane (AbortController) — NOT a lifecycle SoT
- * - InvocationRecord   → cross-process lifecycle SoT (status='running'/'done'/...) — may be zombie
- * - DraftStore         → 300s TTL content cache; draft.updatedAt is the freshness proxy
- * - TurnExecutionStore → durable per-child lifecycle SoT; a scoped running child proves its parent live
+ * - this process's InvocationTracker holds the member's slot for the record's execution; or
+ * - the CLI owner snapshot lists a live owner (its supervisor process still exists) for the
+ *   record's execution and the member.
  *
- * Decision table (KD-3, KD-6 + R1 P1-1/P1-2 from 砚砚 review 2026-05-07):
+ * A running record or TurnExecution child alone proves nothing: when the owner snapshot is
+ * incomplete the startup settlement keeps the previous process's running children, and a turn
+ * whose owner died stays running until something settles it. With a complete snapshot that lists no
+ * owner, such a member is not processing, and the active-execution read-repair ends the record.

+ * Without a complete snapshot nobody can tell whether an owner outside this process lives, so the
+ * evidence that remains is listed, degraded: the user still sees it and can stop it (F117 KD-10:
+ * running and not running are the only states; Stop settles an execution it cannot verify, AC-E7).
+ * - A running child stands in for its owner: an owner that outlives this process started its turn,
+ *   and so its child, before this process started.
+ * - When the caller took a snapshot and it is incomplete, a running record that nothing else lists is
+ *   listed through its members, named by the record: a control surface must keep an execution it
+ *   cannot verify stoppable. A caller that takes no snapshot (sidebar presence) asks only whether
+ *   anyone runs the thread, and a record with no slot, owner or child answers no.

- * ownership, not just timing:
- *  - **slot owner** = the cat's earliest-anchored draft (slot was running before/when that draft
- *    was first created → it's the slot that produced this draft). Pre-computed in
- *    `slotClaimedByDraft` (Map<catId, draft>).
- *  - **STRONG (R3 P1)**: only the slot's owner candidate (record+own-draft OR draft-only owner)
- *    may use record+tracker / tracker+draft. Other candidates whose drafts merely overlap the
- *    slot in time get rejected from these tracker-backed sources.
- *  - **WEAK**: same-cat has exactly one running record AND record.createdAt <= slot.startedAt
- *           AND no other draft strongly claims this slot — fallback for records without their own
- *           draft (single-record-per-cat is unambiguous).
- *  R3 P1 closes the loophole where two candidates' drafts both individually anchored the slot in
- *  time but only one was the true owner: timing-only `slotAssocWithDraft` was reverse-claiming.
+ * QueueProcessor turns a record running only after the tracker takes its slots, so a turn that only
+ * holds a processing reservation is still queued and is not listed here. A slot whose execution has
+ * no running record yet (the few awaits between the tracker taking the slot and the record turning
+ * running), or whose execution the tracker cannot name, is this process's and is listed, degraded.
  *
- * **Enumeration** (R1 P1-1 + F254): candidate set = running records ∪ drafts (by invocationId)
- *  ∪ durable running child executions (by parentInvocationId).
- *  Drafts without a record can still surface as live via the 'tracker+draft' fall-back path,
- *  preserving messages.ts:1400-1406 hotfix3 behavior (AC-B5).
- *
- * `record.updatedAt` is NOT a heartbeat — it changes on status transitions only,
- * so we use `draft.updatedAt` as the freshness signal (DraftStore.touch() refreshes
- * on every stream chunk). Zombie threshold defaults to 2× DraftStore TTL = 600s
- * and ONLY applies when neither a fresh draft nor a durable running child exists, so
- * long-running streams and no-draft handoff gaps are never mistakenly killed.
+ * The response R is checked by the caller (live-invocation-projection): a member whose R is already
+ * terminal is not processing. Nothing here classifies zombies: the F118 owner reaper, the KD-21
+ * startup settlement and the active-execution read-repair end turns, and none of them reads drafts.

+/**

+ *

+/**
+ * The single rule that decides whether a queue identity is already settled.
+ *
+ * Two scripts admit rows: this file's ledger-only enqueue, and the combined message+Queue append
+ * that publishes a visible notice in the same transition. Both must reach the same verdict about
+ * what counts as a replay, so they share this function verbatim rather than each carrying a copy
+ * that can drift.
+ *
+ * For a `private_input` the receipt is the identity of record, and it is written in the same
+ * transition as the row — so it exists while the row is live and survives after the row is retired
+ * at the processing boundary. It is therefore compared FIRST, whatever state the row is in.
+ *
+ * Checking the row's mere existence first was a hole. A live row answered `settled` without ever
+ * looking at the envelope, so a different payload reusing a live key got past this preflight; the
+ * caller then published the visible notice and only afterwards compared fingerprints in
+ * TypeScript and raised. By then the thread already showed a "triggered" line for work that was
+ * refused — the exact half-commit the single transition exists to make impossible. A retired key
+ * refused the same envelope correctly, which is what made the gap easy to miss.
+ *
+ * A bound row has no receipt: its durable winner is the message index, so it keeps answering from
+ * the row itself.

-/**
- * F254 Phase D — Stream Output Freshness Check
- *
- * Lightweight "stale or fresh?" check for the route-serial stream output path.
- * Unlike the Phase A gate (checkFreshnessForPostMessage) which holds or forwards
- * MCP callback messages, this check runs before the cat's final text output is
- * stored via messageStore.append(). It cannot hold (text is already generated),
- * but it CAN:
- *   1. Detect staleness (unseen messages arrived during processing)
- *   2. Return metadata so the caller can mark + force re-invoke
- *
- * Design principles:
- *   - Fail-open: any error → returns fresh (don't block message storage)
- *   - Self-message exclusion (AC-D5): cat's own messages don't count as unseen
- *   - Queue-aware: checks F117 InvocationQueue for pending (not yet delivered) messages
- *

- * routing pill ("A → B").
- *
- * Both dispatch families write through here so the projection can never disagree with the
- * scheduling mode that actually ran:
- *  - serial   — route-serial.ts yields `a2a_handoff` events for an ordered worklist; the
- *               SSE/message routes persist them via `persistA2ARoutingMessage`.
- *  - parallel — the multi-mention callback route fans out N independent Queue entries and
- *               calls `emitParallelRoutingPills` for the same projection surface.
- *
- * Before this module existed the parallel path emitted no pill at all and the serial path
- * emitted N identical "→" pills at the same millisecond — so a sequential worklist and a real
- * fan-out were indistinguishable to the reader (#1291).

- *   → dual-path bug (double-fire + uncontrollable children + infinite recursion)
- *
- * AFTER F27: callback detected @mentions → pushes targets to parent worklist
- *   → single path, shared AbortController, shared depth limit

+ * with no coalesce key — a second Queue row for one event.

+ *
+ * The producer-unification migration moved every connector producer onto one atomic
+ * `Message + Queue` admission (`deliverConnectorMessage` → `PersistedQueueDeliveryPort`). The
+ * migration's real failure mode was never a wrong algorithm; it was a wrong *wiring* that no gate
+ * could see:
+ *
+ *   - `index.ts` assembled the repo-scan deps into a `Record<string, unknown>`, which erased the
+ *     `ConnectorDeliveryDeps` contract, so `deliveryDeps: { messageStore }` type-checked cleanly
+ *     while the runtime path needed `{ delivery }`.
+ *   - `GitHubRepoWebhookHandler` papered over a missing port with `?? ({} as ConnectorDeliveryDeps)`,
+ *     turning a composition bug into an undefined-property crash inside a scheduled task.
+ *
+ * Both are now structurally impossible (the deps objects carry their real types again), but types
+ * only guard the paths TypeScript can see. This file pins the runtime half: a mis-wired producer
+ * must fail loudly and name the actual defect, and a correctly wired one must reach the port.

+ * canonical actor identity every downstream consumer reads — message-bundle author grouping keys
+ * on `external:{connectorId}:{sender.id}`, streaming receipts and Queue projection address it, and
+ * the envelope maps it to `{kind:'user', id}`. Deriving it from `label` collapses every member of a
+ * group chat into one pseudo-person named after the room.
+ *
+ * This test observes production's real seam: the real ConnectorRouter handing an envelope to the

+ * failure modes are the ones production actually has.
+ *
+ * Two properties, and the second is the one that was broken:
+ *   1. Nothing here may reject. Queue commit is the durable boundary; a caller handed an error
+ *      would release its claim and record "nothing was written" about committed work.
+ *   2. The drain is not downstream of the UI broadcast. A wake nobody drains is a wake nobody
+ *      receives, and a failed Queue-panel refresh has no bearing on whether a committed row runs.

+ * final state under compare-and-set is not enough — the send happens before that write, so a
+ * publisher that had merely READ `pending` could still deliver after a suppressor had already won,
+ * and one outcome would produce two successful side effects: the owner is woken about a conflict
+ * that no longer exists, while the record claims it was suppressed.
+ *
+ * These cases pin the interleaving deterministically with a barrier, in both orders, rather than

-/**
- * F-coalesce: A2A 同一只猫连发两次 at 的去重/合并 bug
- *
- * 现象（co-creator 2026-05-30 报）：cat 在一个 turn 内对同一只猫连发两条
- * post_message / cross_post（都 @ 同一只猫），期望"合并在一起 at 出来"
- * 或"去重，后者才是真实意图"。实际：第一条先被独立执行（可能是错误行动），
- * 第二条之后又独立执行 —— 队友被误导 / 先跑错第一步。
- *
- * 根因：
- *  1. A2A dedup 守卫 hasQueuedAgentForCat 只检查 status==='queued'（故意的，
- *     让 processing 时还能排新 handoff）。
- *  2. 但 A2A entry autoExecute:true → enqueueA2ATargets enqueue 后立即
- *     tryAutoExecute → 第一条几乎瞬间从 queued 变 processing。
- *  3. 第二条到达时第一条已 processing 不是 queued → dedup 失效 → 第二条
- *     照常 enqueue → 两条独立 invocation 串行跑。
- *
- * 对照：用户消息（operator 连发两条）走 collectUserBatch → content 拼接合并。
- * agent A2A 路径完全没有 coalescing。
- *
- * 修复（coalesce-or-supersede）：
- *  - 第一条还 queued（没开跑）→ 合并 content（operator 同款，无竞态，不丢信息）
- *  - 第一条 fresh processing（已开跑）→ abort 正在跑的 + enqueue 第二条
- *    （last-wins，避免重跑已部分执行的第一条；满足"后者才是真实意图"）

- * F317 Live dispatch adoption: completeAdopted fence tests.
- *
- * A Live carrier invocation can complete dispatches that were not its own
- * invocation trigger, via the adopted dispatch path. This requires:
- * 1. Both isLiveCarrierInvocation and getReadEvidenceForMessage deps provided (fail-closed otherwise)
- * 2. The predicate returns true for this invocation
- * 3. Durable, invocation-bound read-evidence covers the adopted message
- * 4. The adopted source message targets this cat in this thread
- *
- * The existing complete() path must remain unchanged (regression guard).

- * 砚砚 R5 correctly killed `a2a-routing-projection-boundary.test.js`: it scanned one file and
- *判 provenance by whether a variable name contained "admitted", so naming the requested list
- * `admittedRequested` passed it. A guard that a rename defeats is worse than none — my own words,
- * applied to my own guard.
- *
- * These are behaviour tests over the two invariants, parameterised by ENTRY POINT, because every
- * round of this PR was lost to an entry point nobody had enumerated:
- *   INV-1  the projection's claimed schedule == the schedule that was actually admitted
- *   INV-2  every admitted target converges, and every group settles without waiting for a timeout
- *
- * ADDING AN ENTRY POINT MEANS ADDING A ROW HERE. That is the enforcement — not a regex.

-/**
- * F086/F216 (#1291 field incident): multi-target A2A dispatch intent must be EXPLICIT and HONEST.
- *
- * Field evidence: a cat wrote two line-start @mentions in one reply and stated "并行，不串行" in
- * prose. route-serial pushed both onto ONE ordered worklist and only the first target ever got an
- * invocation — but the projection layer emitted two identical "A → B" pills at the same
- * millisecond, so the reader saw a fan-out that never happened (silent semantic downgrade).
- *
- * Contract locked here:
- *  1. Scheduling mode is carried STRUCTURALLY on every handoff — never inferred from how many
- *     targets appeared or in what order.
- *  2. Inline line-start @mentions are serial BY CONTRACT, and the runtime SAYS SO (requirement 4:
- *     legacy multi-@ may not keep silently impersonating parallel). No NLP over the message body.
- *  3. The user-visible projection distinguishes "serial 第 N/M 棒" from "parallel fan-out".
- *  4. Serial execution really is strictly ordered: target 2 starts only after target 1 terminates.

- * F167: refusal -> explicit recovery -> next generation, through the real callback route, admission service, lease
- * state machine (memory or isolated Redis), queued-message custody CAS and the startup reconciler.
- *
- * Adapted from codex61-sol's PR #5100 review reproduction: the refusal for an action interrupted after a holder read it
- * pointed the predecessor at an explicit replace that could never succeed (the lease stays active and replace required
- * `replaceable`). This file fails if the advertised recovery is not actually executable, and guards that nothing else
- * (a live generation, a request body) can unlock replacing an active generation.
- *
- * Runs against in-memory stores by default; under the isolated Redis runner it uses RedisActionSuccessorLeaseStore and
- * RedisMessageStore on a private key prefix.

 /**
- * #80: Tests for GET /api/messages draft merge behavior.

+ *
+ * Every dispatched cat turn owns a response message R, stored empty at admission as a
+ * `processing` lifecycle response whose `lifecycle.invocationId` is the child turn id.
+ * DraftStore keeps that turn's recoverable streamed body under the same id, and the client
+ * renders history by message id only — so a draft is nothing but R's in-flight body.
  *
  * Verifies:
- * 1. First page (no cursor) includes active drafts
- * 2. Pagination (with before cursor) excludes drafts
- * 3. invocationId-based dedup filters drafts that match formal messages
- * 4. userId isolation: drafts scoped to requesting user
- * 5. Draft messages have isDraft flag for frontend streaming indicator
+ * 1. Any page: a draft folds into its response on whichever page holds R (before cursor too)
+ * 2. A draft folds into the processing response with the exact lifecycle.invocationId
+ * 3. A draft without a processing response on the page is ignored (never a record, never deleted)
+ * 4. Terminal responses are never overwritten by a stale draft
+ * 5. userId isolation: drafts are scoped to the requesting user

- * must agree with /api/messages on canonical liveness rules (record + tracker + draft).

  *
  * Coverage:
- * - AC-B3: record running + tracker missing + fresh draft → /queue.activeInvocations
- *   includes the invocation (pre-F194 was tracker-only → empty).
- * - AC-B4: record running + tracker missing + no fresh draft + age past zombie grace
- *   → /queue.activeInvocations does NOT include the invocation (zombie).
- * - record-missing recovery (R1 P1-1): record absent + tracker slot anchors a fresh draft
- *   → /queue.activeInvocations surfaces it via tracker+draft.
+ * - AC-B3: a running record with only a draft is not processing.
+ * - AC-B4: a running record nobody holds is not processing, however recently it was updated.
+ * - Pre-start window: a tracker slot whose record is not running yet surfaces as the member.
  * - Helper exception fail-open: invocationRecordStore.listRunningByThread throws →
  *   handler logs + falls back to tracker-only enumeration (endpoint never 500s).

+ * A streamed draft is not liveness. So:

+ *          streamed body (F117: a draft is the body of that R, never a `draft-*` record), and
+ *          /queue lists nobody as processing. The active-execution read-repair settles such a
+ *          record once a complete owner snapshot shows no owner.
+ *   AC-B4: with neither an owner nor a draft, neither endpoint shows the turn.

-/**
- * F194 Phase Z — namespace-aware canonical read model RED tests.
- *
- * 砚砚 R1 拍板（2026-05-09）+ R1 P1 三条修正：
- *   - parent recordStore invocation（routes/messages.ts:695 创建，整条 multi-cat 链共享）
- *   - per-cat-turn registry invocation（invoke-single-cat.ts:300 创建，drafts 用它做 invocationId）
- *   - 两个 namespace 不能合并 stamping（A 风险大），不能 hotfix rule（C 治标）
- *   - helper 走结构化 dep：getTurnInvocation + getLatestTurnInvocationId
- *
- * 测试覆盖 AC-Z2 四类场景（α/β/γ/δ）。所有测试现在应该 RED——helper 还没加 namespace
- * dep，会把 parent 当 record-only/pending、child 当 tracker+draft no-record，结果裂成
- * 两个 ghost identity。

- * F194 Phase Z4 — Routes integration test reproducing runtime split symptom.
+ * F194 Phase Z4 → F117 KD-23 — routes integration for the runtime split symptom.
  *
- * Reproduces the exact runtime state from thread_moxnb78ckc36xhga (2026-05-09 03:35):
- *   - parent recordStore invocation P1 status=running for ~4 minutes
- *   - child registry invocation C1 with parentInvocationId=P1, fresh draft for opus-47
- *   - tracker slot for opus-47 present
- *   - formal message persisted with extra.stream.invocationId=P1 (multi-cat chain mid-flight)
+ * Runtime state from thread_moxnb78ckc36xhga (2026-05-09 03:35): a multi-cat chain whose parent
+ * record had been running for ~4 minutes while the member now answering had just started. /queue
+ * showed the member's timer at 4 minutes although its content was fresh.
  *
- * Pre-Phase-Z observed bug:
- *   - /messages.helper.active had {invocationId=P1, source=record-only} + {invocationId=C1, source=tracker+draft no-record}
- *     → 2 ghost identities for what's actually 1 in-flight chain
- *   - /queue.activeInvocations dedup kept earliest startedAt = P1.updatedAt (4 min ago)
- *   - User-facing: bubble timer chip stale (4 min) but content fresh (a58a8757 streaming)
- *
- * Post-Phase-Z expected:
- *   - helper.active = 1 entry per cat, source='parent+child+tracker', startedAt=child createdAt
- *   - /queue.activeInvocations[].startedAt = child createdAt (NOT parent.updatedAt)
- *   - /messages: child draft surfaces (orphan filter respects child id namespace)
- *   - Both endpoints agree on namespace identity
+ * F117 KD-23 keeps the fix without drafts or the registry namespace bridge: the member is live
+ * because this process's tracker holds its slot, and its start is the run the slot has bound
+ * (activeRun.startedAt), not the chain's start. /messages still folds the member's draft into its
+ * processing response by lifecycle.invocationId, never as a `draft-*` record.

-/**
- * F254 Freshness Gate Integration Tests (Phase A — Layer 3)
- *
- * Tests the freshness gate wiring in the post_message callback context:
- * - checkFreshnessForPostMessage helper extracts unseen messages and delegates to FreshnessGateService
- * - Held envelope response format matches spec
- * - acknowledgeHeld escape hatch
- * - seenCursor push on forward
- * - Self-message exclusion in the wiring layer
- *
- * These tests use mock stores — Layer 1 (Redis-backed) and Layer 2 (pure logic)
- * are independently tested.

-/**
- * F254 B3 — createFreshnessReinvokeCheck factory tests.
- *
- * Tests the composition layer that bridges stores → decideFreshnessReinvoke.
- * Uses in-memory stubs (not Redis) since the pure decider is already tested.
- *
- * P1-1/P1-2 review fixes:
- * - userId is now required in check params
- * - getSeenCursor dep reads real per-(user,cat,thread) cursor (not lastNoticeToolCallNum)
- * - seenCursorCaughtUp uses message ID comparison (not unresolvedNotices.length === 0)
- * - shouldReinvoke=true returns reinvokePrompt (spec §B3 content-free prompt)

-/**
- * F254 FreshnessNoticeService Tests (Phase B — B1)
- *
- * Unit tests for the read-only tool notice piggybacking logic.
- * Tests the decision logic: when to attach a "you have unseen messages" notice
- * to a read-only MCP tool response.
- *
- * Uses mock stores (not Redis) — Redis integration tested in B0 tests.
- *
- * Spec constraints:
- * - Only read-only tools get notices
- * - Frequency: every N tool calls (N=5), max 3 per invocation
- * - Content-free: sender names + count only, NO message content
- * - messageFilter: must not notice on hidden messages
- * - Records notice_attached event in FreshnessAttentionEventLog
- * - Updates FreshnessInvocationState counters

-/**
- * F254 Queue-Aware Freshness Gate Tests
- *
- * Bug found 2026-06-29 (operator live test): F117's isDelivered() filter at the
- * store layer hides queued messages from the freshness gate, causing false-forward
- * when the user sends messages while the cat is running.
- *
- * These tests verify that:
- * 1. checkFreshnessForPostMessage holds when InvocationQueue has pending entries
- * 2. ThreadUnseenChecker returns unseen result when queue has pending entries
- * 3. Queue check is a fallback — delivered unseen messages take precedence
- * 4. Self-source queue entries (from the same cat) don't trigger hold
- * 5. acknowledgeHeld still works as escape hatch

- * F194 Phase A: Tests for getThreadLiveInvocations canonical read model helper.

- *   1. record running + tracker active           → active, source='record+tracker', degraded=false
- *   2. record running + tracker missing + fresh   → active, source='record+draft', degraded=true,

- *   3. record running + tracker missing + stale   → zombie (no_tracker_no_fresh_draft_age_exceeded)
- *   4. record running + tracker missing + grace   → active, source='record-only', degraded=true,
- *                                                   reason='liveness_pending'
- *   5. record not running                          → not exposed
+ * A member is processing when its record is running and someone verifiably runs its turn:
+ *   - this process's tracker holds its slot for the record's execution   → record+tracker
+ *   - the owner snapshot lists a live CLI owner for it                    → record+owner
+ * A running child with neither only stands in for its owner while the snapshot cannot tell, because
+ * the caller has none or it is incomplete                                 → parent+child-execution, degraded
+ * A slot whose execution has no running record yet                        → tracker-only, degraded
  *
- * Plus AC-A4: active[] and zombies[] mutually exclusive on invocationId.
- * Plus AC-A6: threshold injection works.
- * Plus AC-A5: helper does not mutate any store (read-only).
+ * Nothing reads a draft or a timestamp, and nothing is classified as a zombie.

-/**
- * F167 PR-A — a fail-closed managed-hold disposition error says which branch it fell on.
- *
- * `managed_hold_disposition_replay_mismatch` is thrown at three places in the service, and the caller used to get
- * the same bare code from all of them:
- *   1. a terminal exists for this wake but its identity (cat, source, task, a valid disposition) does not match;
- *   2. the SAME invocation already recorded this wake with a different disposition;
- *   3. after the write, the terminal could not be read back (or read back as something else).
- * Each now carries the branch and, where one exists, the stored terminal (disposition, invocationId, at). The
- * guard is unchanged and still fails closed.
- *
- * These call the two assertion steps directly: they are pure over (event, auth, ids), and the full service
- * harness would add nothing to what they decide.

-/**
- * Queue gate thread-level regression test
- *
- * Bug: messages.ts used invocationTracker.has(threadId, primaryCat) which only
- * checks the target cat's slot. When cat B is active in the thread but user
- * sends to cat A, the message bypasses the queue and executes immediately,
- * causing two cats to talk simultaneously.
- *
- * Fix: Use has(threadId) (no catId) to check if ANY cat is active in the thread.

- * execution layer applies side effects (worklist.push, updateStreakOnPush, span, yield). No mutation
- * here — streak is predicted read-only via ctx.peekStreak (砚砚 OQ3, plan 约束1).

 /**
- * @not-found feedback regression
- *
- * Bug (docs/bug-report/2026-05-29-invocation-stale-active-recovery §3.2 Thread 1 trigger):
- *   When user sends "@kimi 你来做" but kimi is disabled/not-in-roster:
- *   - `resolveCatTarget` → cat_not_found error → routing_warnings populated
- *   - AgentRouter.resolveTargets finds no valid mentions → falls back to default cat
- *   - User gets NO feedback that @kimi was not found → confusion (opus answers unexpectedly)
- *
- * Fix: resolveTargetsAndIntent returns routing_warnings alongside targetCats/intent/hasMentions.
- * Callers (messages.ts) can use this to emit a user-visible warning.
- *
- * RED → GREEN after modifying AgentRouter.resolveTargetsAndIntent to expose routing_warnings
+ * Ordinary prose mention parsing does not invent routing errors for unmatched @ text.
+ * Valid members remain targets; common send applies fallback when none are available.
+ * Explicit A2A recipient validation is a separate contract.

- *   - hadSubstantiveToolCall=true   → 干活（豁免）
- *   - outputLength > OUTPUT_LEN_T(200) → 讨论/设计（豁免）
- *   - 两者都否 → 纯语言惯性（streak++）
- *
- * 不传 activity 视为向后兼容——按旧逻辑累加（pushToWorklist 在 Task 3 之前还是不传）。

This durable fact needs no action lease, coordination generation, replacement, or issuer route; prose is never parsed. The server carries a stable id across active hops. Every cross-thread post supplies an explicit routing credential, so a line-start @mention or structured targetCats after terminal always starts a new active routing generation and remains subject to the normal loop-streak guard. If terminal reveals genuinely new work, start a new coordination with phase=active instead of ACKing the closed chain. GOTCHA: For a direct named external action, pass action + explicit clientMessageId + targetCats. For operator-gated new responsibility, pass proposedAction with effectClass=assign_work instead; action and assign_work remain mutually exclusive. Output: direct action admission posts and queues one fenced carrier; assign_work publishes one pending approval card and posts nothing to the target until approval atomically acquires the fence. Existing standing reuses the same CAS via claimOrigin=\"existing_standing\" + groundingEvidenceRef. returnToPredecessor sends a rejected single generation to the server-persisted predecessor; parallel mode records only the rejecting holder terminal. Structured action metadata currently requires invocation-token auth; agent-key callers fail closed with the non-retryable action_agent_key_unsupported status and never send an unfenced fallback. F247: gpt-pro agent-key returns carry only the exact replyTo from the runtime delta; authorization stays in server custody. Fallback must use replace with the active leaseId/generation after server-recorded terminal evidence. Use mode=parallel + parallelIntent only for deliberate independent review, #ideate, or explicit operator fan-out. TIP: The sub-thread \"## 主 Thread\" header includes exact routing credentials (threadId + targetCats/handle) — copy them directly.",

- * WHY THIS EXISTS (F086/F216 sub-item, #1291 field incident):
- * A cat wrote two line-start @mentions in one reply and stated "并行，不串行" in prose.
- * The runtime pushed both onto ONE sequential worklist (route-serial.ts) and only ever
- * created the first target's invocation — but the projection layer emitted two identical
- * `a2a_handoff` pills at the same millisecond, so the UI drew two equivalent arrows.
- * The scheduling mode was carried by nothing at all; readers inferred it from the fact
- * that two targets appeared side by side. That is a silent semantic downgrade.
- *
- * CONTRACT:
- * - Mode is ALWAYS explicit and structured. It is never inferred from how many targets
- *   there are, from their ordering, or from natural language in the message body.
- * - `serial`   — one ordered worklist; target N+1 starts only after target N terminates.
- *                Inline line-start @mentions are serial BY CONTRACT (see A2A_INLINE_MENTION_MODE).
- * - `parallel` — independent fan-out; every target obtains its own invocation/Queue custody
- *                before any target reaches a terminal. Only reachable through the structured
- *                `cat_cafe_multi_mention` + `action.mode="parallel"` + `parallelIntent` path.

+ * The one rule for whether a hold-ball card may still offer "取消持球".
+ *
+ * Cancelability had copies. The server owns the canonical answer
+ * (`isCancelableHoldBallTask`) and returns it from the hold status endpoint,
+ * but a rendered card can only ask that endpoint over the network — so when the
+ * probe was unavailable the card fell back to re-deriving the answer from
+ * `source.meta.phase`, and that copy was wrong. It treated `wake` and
+ * `terminal` as the only terminal phases, while four real producers announce a
+ * terminal under `phase:'status'` — launch cancellation, spawn/runner loss,
+ * missed wake window, and wake-admission failure — and a fifth marks its
+ * terminal with `terminalReceipt` and no phase at all. A finished hold
+ * therefore kept live cancel controls on every one of those paths whenever the
+ * probe failed.
+ *
+ * `phase` is a presentation label. It was never a cancelability signal, and
+ * widening the set of "terminal phases" would only move the same guess to a
+ * new copy. Each producer already knows, at the moment it writes the card,
+ * whether the hold it describes can still be canceled — so it states that here
+ * and the consumer stops deriving it.
+ *
+ * A card stating `false` is a durable *local* terminal fact: it remains true
+ * with no network, which is why it outranks the probe. The probe stays
+ * authoritative only where no card has stated a terminal.

+ * F117 baseline B (2026-09-28): while replies stream, `messages` changes on nearly every commit. An effect keyed on
+ * it that calls setState even when nothing changed leaves the "no change" check to React, and React cannot skip the
+ * call while the component has other work pending, so each call becomes a real update scheduled from the commit
+ * phase. The React build Next ships counts those as nested updates and throws "Maximum update depth exceeded" once a
+ * chain passes 50 (reproduced in alpha with two live streams, see the baseline record).
+ *
+ * These tests count the state updates scheduled while a component's passive effects run, through the profiling
+ * hooks React DevTools uses. The hook must exist before react-dom loads, so react-dom is imported dynamically.

- * F173 A.12 — invocation-driven suppression cleanup invariants.

- * 砚砚 round 5 review pinned two regression points:

- *      invocation (codex round 2/4 case)
- *   2) invocationless stream must NOT be permanently dropped by an old suppression
- *      marker (codex round 3 case)
- *
- * Both surfaces (active = useAgentMessages, background = useAgentMessages) read

- * it's the simpler integration point — the active-handler path goes through the
- * same shouldSuppressLateStreamChunk semantics with identical fail-open and

- * F194 Phase Z3 R16 — Cloud Codex P1: suppression key must use turn id, not parent.
- *
- * Cloud Codex P1 finding (PR #1619):
- * "Overwriting every outbound event to invocationId: createResult.invocationId
- *  collapses per-turn identity to the parent chain ID, but active-stream
- *  suppression still keys off invocationId. In a same-parent multi-turn flow
- *  for one cat (e.g. opus → codex → opus), once the first opus turn is marked
- *  replaced, later opus chunks with the same parent ID are treated as stale
- *  and dropped, so the later bubble can disappear."
- *
- * Scenario reproduced:
- *   - parent = P-1 (chain SoT for opus → codex → opus)
- *   - opus turn 1: turnInvocationId = T-1
- *   - opus turn 3: turnInvocationId = T-3
- *   - After turn 1 is marked replaced (callback finalize), turn 3 stream
- *     chunks must NOT be suppressed because they're a different per-cat-turn.
- *
- * RED: before R16, suppression keys parent → turn 3 dropped → bubble missing.
- * GREEN: after R16, suppression keys turn (msg.turnInvocationId ?? msg.invocationId)
- * → turn 1 marked replaced under T-1, turn 3 chunks under T-3 pass through.

-/**
- * Regression test for #266 Round 2: socket reconnect eager catch-up replaced
- * store messages while stream was still active, causing Zustand store / useRef
- * desync → duplicate bubbles.
- *
- * Fix: removed the eager requestStreamCatchUp on reconnect (useSocket.ts) and
- * enhanced resetRefs to clear ALL ref maps (not just activeRefs + replacedInvocationsRef).
- *
- * This test verifies the resetRefs enhancement: after calling resetRefs(), the
- * hook must NOT try to recover or append to the old bubble from a prior invocation.
- *
- * Intake source: clowder-ai#378 (selective absorb — resetRefs patch only)

-/**
- * F194 dual-path thread-switch regression — codex live bubble split (saga round 17 root cause).
- *
- * Real operator devtools sample (2026-06-17): a single codex A2A reply in thread Y
- * split into TWO bubbles because the operator's `currentThreadId` switched away
- * (Y → X) mid-reply. `handleAgentMessage` reads `currentThreadId` fresh per
- * message: events while viewing Y take the ACTIVE path; events after switching
- * away take the BACKGROUND path. codex tool/work-log events carry NO
- * `msg.turnInvocationId` (only `invocation_created` does), so the two paths
- * resolve the bubble's turn id from DIFFERENT sources:
- *   - active path binds the bubble to the live turn and records it in the
- *     per-thread runtime ledger keyed (threadId, codex).
- *   - background path `ensureBackgroundAssistantMessage` resolves the turn from
- *     `getThreadState(threadId).catInvocations[codex].turnInvocationId` ONLY. After
- *     the reply finalizes and a NEW codex invocation context lands a DIFFERENT
- *     (shadow) turn there, the late tool events derive a DIFFERENT bubble id →
- *     a second, empty work-log-only bubble → SPLIT.
- *
- * Reproduced end-state matches the real sample exactly:
- *   bubble A (active): id `msg-<persistedTurn>-codex`, the reply text, finalized.
- *   bubble B (background): id `msg-<shadowTurn>-codex`, EMPTY content, tool events,
- *     still streaming.
- * Both live in threadStates[Y].messages. F5 re-projects from the single persisted
- * record → self-heals to one, proving it is a live-reducer-only split.
- *
- * Z3 redline: the fix only aligns the fallback SOURCE when msg.turnInvocationId is
- * ABSENT (codex tool events). Genuinely different invocation_created turns keep
- * distinct ledger bubbles → distinct turns → stay separate.

- * clearDoneTimeout safety net bug:

- * clearDoneTimeout() is called unconditionally on the FIRST cat's done/error(isFinal),
- * killing the 5-minute safety timer. If a subsequent cat's done(isFinal) is lost
- * (WebSocket issue, server not yielding it), stale invocation slots persist forever,
- * causing ThreadExecutionBar to show "执行中" until F5.
- *
- * Fix: move clearDoneTimeout() inside the `remainingInvocations === 0` block so
- * the timer stays alive while ANY cat is still running.

- *

- *
- *   砚砚 PR #1423 review P1: 旧版 fixture mock 掉 background helper，只验
- *   "delegate 被调用"，没钉 AC-E3 真正关心的 "active→background→active 期间同
- *   invocation 不产生第二个 bubble id"。Task 3-5 迁移期间该 fixture 必须保持绿。
- *
- *   本版本不 mock useAgentMessages — real handleBackgroundAgentMessage 跑通；
- *   只 mock chatStore，断言 store 收到的 message id 在 active 和 bg 路径下都是
- *   同一份（deriveBubbleId(invocationId, catId) → msg-{inv}-{cat} 是 deterministic）。
- *
- * 对外 invariant 不变量（重构后必须保持绿）:
- *   - same invocation across thread switch → 唯一 bubble id (no double-bubble)
- *   - active path 调 store.addMessage with id = `msg-{inv}-{cat}`
- *   - bg path 调 store.addMessageToThread with id = same `msg-{inv}-{cat}`
- *   - invocationless fallback case 也走对应 thread 写路径

- *   When both arrive, we MUST canonicalize to outer so bubble identity stays
- *   stable across active path + background path. Otherwise active gets
- *   `msg-outer-cat`, bg gets `msg-inner-cat` → dup bubble.
+ *   When both arrive, the cat's invocation state MUST canonicalize to outer so
+ *   catInvocations / taskProgress stay keyed by the same parent on the active
+ *   path and the background path. Bubble identity is not derived from either id:
+ *   body events name their stored message (messageId).
  *
  * Invariant pinned (observable through store writes):
  *   - invocation_created (active + bg)        → setCatInvocation invocationId === msg.invocationId
  *   - invocation_metrics.session_started      → setCatInvocation invocationId === msg.invocationId
  *   - task_progress (active + bg)             → taskProgress.lastInvocationId === msg.invocationId
- *   - web_search / thinking / rich_block (bg) → ensureActiveAssistantMessage uses outer for bubble derivation

  *
  * PTY carrier produces text events WITHOUT metadata (transcriptEntriesToAgentMessages).
- * The active-path invocation_usage handler must write model/provider via setMessageMetadata
- * so the MetadataBadge footer ("claude-sonnet-4-6 · claude_interactive_pty") renders.

+ * ("claude-sonnet-4-6 · claude_interactive_pty") renders.
  *
  * Coverage:
- *   - Active path: invocation_usage with model/provider → setMessageMetadata called
- *   - Active path: invocation_usage without model/provider → setMessageMetadata NOT called (backward compat)
+ *   - Active path: invocation_usage with model/provider → metadata written on R, before usage
+ *   - Active path: invocation_usage without model/provider → metadata NOT written (backward compat)

- * F194 Phase Z8 cloud R3 P1 (codex) — dual-id callback-final preservation.
- *
- * Bug: `applyBubbleEventWithRecovery` looks up the pre-reducer stream record
- * with `m.extra?.stream?.invocationId === canonicalInvocationId`. In F194 Phase
- * Z3 dual-id case, the stream row stores `{ invocationId: parent, turnInvocationId: turn }`,
- * but the incoming event carries `canonicalInvocationId = turn`. Direct
- * `extra.stream.invocationId` comparison misses → no synthetic stream record
- * appended → reducer's destructive callback overwrite drops stream content.
- *
- * Fix: use `getBubbleInvocationId(m)` for the lookup so turn-priority matches
- * the event's `canonicalInvocationId` (also turn-priority via
- * `bubble-event-adapter.ts` line 107 `canonicalInvocationId = turnId ?? chainId`).

- * F194 Phase Z3 R20 — Cloud Codex P1: getLocalPlaceholderInvocationId catInvocations
- * fallback must prefer turnInvocationId.
- *
- * Cloud Codex P1 finding (PR #1619 review on R19 444768347):
- * > "When a live local stream bubble has no extra.stream yet, this fallback still
- *    returns catInvocations[catId].invocationId (the parent chain ID). After this
- *    commit, history reconciliation keys use turnInvocationId first, so same-parent
- *    multi-turn flows can miss the intended history match and keep both local+history
- *    bubbles (or reconcile the wrong one). This is most visible when a placeholder is
- *    still unbound during hydration and catInvocations already contains
- *    { invocationId: parent, turnInvocationId: turn }; the local side resolves to
- *    parent while history resolves to turn, breaking stable-key merge."
- *
- * RED before R20: catInv.turnInvocationId set, but fallback returns invocationId (parent).
- * GREEN after R20: fallback returns turnInvocationId when present.

- * F173 Phase A.6 — Shared `replaced invocations` runtime state (bidirectional handoff).
- * F173 Phase B AC-B6 (integration step 5) — internally delegates to the
- * thread-runtime-ledger singleton. The exported API surface stays identical
- * so existing callers (useAgentMessages, useAgentMessages, useSocket,
- * tests) keep working unchanged.
- *
- * Why the rewrite (砚砚 LGTM-5 non-blocking observation): the previous
- * `Map<key, Set<invocationId>>` had no TTL — long sessions accumulated
- * replaced invocationIds and only cleared on full thread-level cleanup.
- * The ledger uses `Map<threadId, Map<catId, Map<invocationId, {expiresAt}>>>`
- * with explicit TTL so each marker can be evicted independently.
- *
- * TTL choice: SHARED_REPLACED_TTL_MS (10 min) — long enough that no realistic
- * late-event reorder window misses suppression, short enough that abandoned
- * sessions don't grow ledger memory unbounded.
- *
- * Lifetime: process-singleton (delegates to thread-runtime-singleton). Tests
- * still call `resetSharedReplacedInvocations()` to wipe ledger between
- * fixtures — preserves the BeforeEach pattern used across the codebase.

- * - lastObservedExplicitInvocationId replaces the catInvocations fallback that

- * decide action, write back.
- *
- * Behavior:
- * - msg.seq undefined / 0 → no-op (legacy producer, graceful degradation)
- * - msg.seqEpoch differs from lastSeqEpoch (and lastSeq>0) → epoch-change (server
- *   restart, sequencer instance changed) → reset lastSeq + trigger catchup +
- *   seed with new (epoch, seq). 砚砚 R1 P1 fix: without this, server restart
- *   silently breaks gap detection until server's new seq exceeds client's stale
- *   high-water mark (potentially many "late" rejections during catch-up window).
- * - msg.seq present, lastSeq=0 → first event for this thread, seed lastSeq + epoch
- * - msg.seq <= lastSeq → late event (out-of-order or duplicate); record debug, don't update
- * - msg.seq === lastSeq+1 → monotonic advance, update lastSeq
- * - msg.seq > lastSeq+1 → GAP. record `pendingCatchUpTargetSeq=incomingSeq`,
- *   fire `requestStreamCatchUp(threadId)`, do **NOT** advance lastSeq (cloud
- *   P1 watermark preservation — failed/canceled fetch must keep retrying).
- *   useChatHistory's fetchHistory.then() captures pending at fetch START and
- *   calls `acknowledgeCatchUp(threadId, capturedTarget)` on success — that
- *   advances lastSeq to capturedTarget and clears pending only if pending
- *   still equals capturedTarget (砚砚 R6 P1 stale-fetch race fix).
- *
- * Returns the action taken for diagnostics / test assertion.

-   * Stale terminal event guard (Bug-G, shared by `done` + `error`):
-   * Returns true when `msgInvocationId` identifies an older invocation than the
-   * one this cat is currently executing. Used to skip bubble/cat side effects
-   * for late arrivals that would otherwise terminate a newer invocation's bubble.
-   *
-   * Resolution order (latest real slot → catInvocations direct):
-   * 1. `activeInvocations` latest slot for catId, EXCLUDING synthetic
-   *    `hydrated-${threadId}-${catId}` keys from reconnect reconciliation
-   *    (cloud R7: hydrated slots do not represent a real in-flight invocation
-   *    and must yield to a concrete direct binding).
-   * 2. `catInvocations[catId].invocationId` as fallback.
-   *
-   * We prefer activeSlot over direct because `intent_mode` registers fresh
-   * `activeInvocations[inv-2]` BEFORE the new `invocation_created` clears the
-   * previous `catInvocations=inv-1`. A late `done/error(inv-1)` needs the
-   * freshest signal to be marked stale.
-   *
-   * Slot key normalization: non-primary cats are registered as
-   * `${invocationId}-${catId}` in activeInvocations (useSocket.ts), while
-   * terminal events broadcast the bare parent `invocationId`. Strip the
-   * `-${catId}` suffix before comparison so both key forms accept equivalently.
-   *
-   * Returns false when `msgInvocationId` is absent (we can't judge).
-   * Returns true when resolved signal is undefined (no authoritative source →
-   * can't prove the terminal event is for the current invocation → treat as
-   * stale to avoid touching a newer bubble whose events were also lost).

Let me verify the edits are consistent by reading the key sections.All 3 findings are addressed:\n\n1. **P1 (floating window)**: Phase B tech table → \"右侧 TranscriptPanel\"; floating window features moved to Phase C (AC-C5/C6); \"浮动转写窗最小 AC\" section → \"转写窗交付说明\" with Phase B/C split\n2. **P1 (meeting context)**: Removed from Phase B tech table + gap table; moved to Phase C; AC-C4 split into AC-C4a/b/c (MeetingSession binding, rolling window, MeetingContextBlock isolation)\n3. **P2 (diarization)**: Removed from Phase A tech table; gap table Phase changed from \"A(会后)/B/C\" to \"C\"\n\nCommitting and pushing (shared document rule).Now I need to @ 砚砚 for re-review. Let me load the MCP tool.已 @ 砚砚 re-review（`1ff9053d4`）。三个修复：Phase B 技术表改为实际交付的 TranscriptPanel，meeting context 和浮动窗全部移至 Phase C，diarization 从 Phase A 移除。等砚砚确认后继续 Phase C spec。",

- * F194 Phase Z11 — CLI Output stdout consistency (co-creator R15, 2026-05-16).
- *
- * Bug: when projection merges a stream record + a post_message callback into one
- * canonical bubble (Z8 KD-27), bubble origin becomes `callback`. ChatMessage.tsx:122
- * only feeds content to `toCliEvents` when `origin === 'stream'`, so the merged
- * (callback-origin) bubble's CLI Output loses its stdout — only tools remain.
- * co-creator wants CLI Output behavior IDENTICAL whether or not there's a post_msg.
- *
- * Z11 initial fix kept Z8 merge and exposed cliStdout/speechContent. Runtime
- * evidence later showed this still violates the user's expected model:
- * post_message speech is its own bubble, while stream-origin CLI work logs stay
- * in the CLI bubble. Projection must therefore split callback-origin speech
- * records from stream-origin work-log records even when they share the same turn.

+ * A connector notice that reaches the timeline through Queue delivery must stay a connector.

+ * notices. Before that, those notices stored no `from` at all, so the server synthesized
+ * `{kind:'external', connectorId}` from `source` and every consumer derived `connector` for free.
+ * The server timeline projection already handles the explicit form —
+ * `external || plugin || (system && source)` — but the client copies of that same rule never
+ * learned the `system && source` branch. So a hold-ball notice arrived as `type:'system'` with no
+ * `source`, `ChatMessage`'s `isConnector && message.source` gate failed, and the hold-ball card
+ * silently degraded to a plain text block: the exact regression that 3057 green tests and 16 green
+ * CI checks could not see, because every one of them asserts persistence or the REST projection,
+ * never what the live socket hands the store.
+ *
+ * These cases pin the store-level contract: delivery carries `source` through and classifies the

- * F183 Phase E AC-E2 — chatStore mutation path coverage audit.
- *
- * 砚砚 R1 P1 → R2 P1 closure: writers gated end-to-end. Three layers:
- *   1. Pre-set TD112 in-store dedup (addMessage / addMessageToThread)
- *   2. Pre-set strict-mode runtime gate (replaceMessages /
- *      replaceThreadMessages / hydrateThread via
- *      `forwardStoreInvariantViolationsStrict`) — strict OFF = no-op,
- *      strict ON = scan + throw before set() so bad state never lands
- *   3. Reducer-driven paths additionally forward violations from
- *      `applyBubbleEvent` results to `recordBubbleInvariantViolation`
- *      in useAgentMessages.ts (existing wire-up)
- *
- * COVERAGE TABLE (chatStore.ts mutation entry → invariant gating):
- *
- * | Entry                     | Gating mechanism                                   | Status |
- * |---------------------------|----------------------------------------------------|--------|
- * | addMessage                | TD112 dedup (findAssistantDuplicate, line ~1330)   | ✓ in-store |
- * | addMessageToThread        | TD112 dedup (line ~1932)                            | ✓ in-store |
- * | replaceMessages           | Pre-set strict gate (forwardStoreInvariantViolationsStrict) | ✓ writer-self |
- * | replaceThreadMessages     | Pre-set strict gate (same, runs before current/bg branch split) | ✓ writer-self |
- * | hydrateThread             | Pre-set strict gate (after merge, before set())     | ✓ writer-self |
- * | prependHistory            | Caller-driven (history fetch payload trusted)       | ✓ caller |
- * | replaceMessageId          | Id swap (cannot create new identity)                | N/A |
- * | patchMessage              | Patches existing msg (no new bubble)                | N/A |
- * | appendToMessage           | Appends content (no new bubble)                     | N/A |
- * | removeMessage             | Removes (cannot create duplicate)                   | N/A |
- * | clearMessages             | Empties (cannot create duplicate)                   | N/A |
- *
- * "writer-self" gate fires under strict mode (BUBBLE_INVARIANT_STRICT=1 /
- * NEXT_PUBLIC_BUBBLE_INVARIANT_STRICT=1 / localStorage flag) and is a
- * 1-instruction early-out otherwise — zero cost in production default.

-/**
- * F194 Phase Z8 — Unified Canonical Bubble Projection
- *
- * Pure function: raw assistant records → canonical UI bubbles.
- * Same projection rule used by:
- *   - live reducer (each event → re-project the cat's raw record buffer)
- *   - hydrate (`mergeReplaceHydrationMessages` → project history records)
- *
- * Contract (KD-27, AC-Z20):
- *   - Stream/work-log records group by `(catId, getBubbleInvocationId(msg))` —
- *     same key as the legacy hydrate `streamKey`.
- *   - Callback-origin records with their own message id are MCP `post_message`
- *     speech, not CLI work logs; they group by their callback message id. This
- *     keeps post_msg as a separate bubble while preserving stream grouping for
- *     tool/stdout output.
- *   - Exact-key callback_final records whose id equals an existing stream record
- *     id are terminal updates for the stream bubble, not post_msg speech; they
- *     stay in the stream group to avoid duplicate bubble ids.
- *   - Records without catId or invocation key are passed through unchanged
- *     (system / user / un-namespaced bubbles).
- *   - Within a group, records are sorted by `timestamp asc` then `id asc` for
- *     determinism. The *first* (earliest) record's id becomes the canonical
- *     bubble id, but a callback record (origin === 'callback') wins the id if
- *     present — callbacks are the cat's own finalize step and their ids are
- *     server-canonical.
- *   - Content: concat non-empty `content` fragments by ts asc, separated by
- *     '\n\n'. Empty fragments skipped to avoid leading separators.
- *   - toolEvents: dedupe by `event.id`, ordered by record ts then event ts.
- *   - rich blocks (`extra.rich.blocks`): dedupe by `block.id`, preserve order
- *     (first occurrence wins).
- *   - thinking: concat non-empty `thinking` fragments by ts asc, separated by
- *     '\n\n'.
- *   - isStreaming: callback/terminal-aware (砚砚 R1 P1)。优先级：(1) 任一 record
- *     是 callback origin → false (callback 是 cat 自己 finalize，认 done); (2) 否则
- *     按 ts asc 取最后一个 record 的显式 isStreaming 值；(3) 没有显式值 → false。
- *     **不能用 ANY=true** — 旧 stream record 残留 isStreaming=true + 后到 callback
- *     final 时，ANY 会把投影 bubble 当成仍 streaming，复活我们要杀的 live 残留。
- *   - origin: 'callback' for callback groups; else 'stream'.
- *   - timestamp: earliest record ts (for stable sort).
- *
- * Why this contract evolved: Z8 made live ≡ hydrate by sharing projection.
- * Z11 fixed a blind spot where stream stdout disappeared after post_msg merge.
- * Runtime evidence then clarified the intended UI model: post_msg speech is its
- * own bubble; CLI work logs stay in the stream bubble. Projection therefore
- * still unifies live/hydrate, but does not merge callback speech into stream.
