 Before every proposed step, `Inbox.claim(target)` atomically removes the complete batch: all `next-step` messages and, at a turn boundary, one `next-turn` message. At the initial boundary the loop first commits `turn/start`, so the claim and its single `agent/pre-step` decision have durable turn ownership. Claiming records normalized `agent/inbox/spliced` pure deletions with no outcome. The loop then emits `agent/inbox/claimed { message, turn }` once per claimed message and awaits the waterfall with that exclusive batch and `{ turn, step, signal }`.

There is no `agent/prompt-prepare`, `agent/prompt-submit`, or `agent/step` seam.

Replacement may change identity and emits the old message as discarded followed by the new message as inserted. Every insertion emits `agent/inbox/inserted { message }`; an ordinary removal records `outcome: 'canceled'` and emits `agent/inbox/discarded { message }`. These live events add no placement, outcome, or batch fields.

 ## Problem
 
-The react-loop simplification changed durable events while retaining `SESSION_FORMAT_VERSION` 0. Stored sessions from the change's base contain `steering/message`, a `turn/start.trigger`, and `turn/end` records without the current top-level `step`; their terminal reasons also use coarse `aborted`, separate `disposed`, and two older error payloads. Current surface and turn invariants cannot replay those records directly.
+The react-loop simplification changed durable events while retaining `SESSION_FORMAT_VERSION` 0. Stored sessions from the change's base contain `steering/message` and `turn/start.trigger`; their terminal reasons also use coarse `aborted`, separate `disposed`, and two older error payloads. Current surface and turn invariants cannot replay those records directly.
 
 The new durable inbox is not part of this compatibility problem. The base emitted process-local inbox notifications but no `agent/inbox/*` session events, so replaying old history as pending work would resurrect already claimed or discarded prompts.
 
 ## Decision
 
-`PersistenceCoordinator` recognizes the exact pre-react-loop shapes after backend decoding and projects them into the current read view. It removes the obsolete `turn/start.trigger`, converts `steering/message` to the same identified `user/message`, adds the last entered step to `turn/end`, maps old failure facts into the current structured error, folds `disposed` into an aborted turn with the `disposed` cause, and represents coarse aborted records with the persistence-only `{ kind: 'legacy' }` cause because their caller is unavailable.

-The coordinator applies the projection to `load`, `inspect`, adoption, HMR prefix comparison, and `readFrom`. A seek-capable `readFrom` normally reads only its suffix; when that suffix contains a legacy event needing an earlier step or replacement identity, the coordinator loads and normalizes the complete prefix before returning the requested seq range.

 The importer does not synthesize inbox splices. A resumed pre-react-loop agent begins with empty pending lists, matching the base runtime's inability to persist pending inbox work. The stored artifact remains append-only and later events use the current format.
 
 ## Alternatives considered
 
-**Treat the same-version records as unsupported.** This follows the pre-release default but strands sessions produced by the PR base even though the removed steering content, turn step, and terminal facts have complete mappings.

 新的持久 inbox 不属于此兼容性问题。该基线会发出进程本地 inbox 通知，但不会产生 `agent/inbox/*` 会话事件，因此将旧历史回放为待处理工作会让已经领取或丢弃的提示词再次执行。
 
 ## 决策
 
-`PersistenceCoordinator` 会在后端解码后识别 react-loop 重构前的确切形状，并将其投影为当前读取视图。它移除已废弃的 `turn/start.trigger`，把 `steering/message` 转换为同一条带标识的 `user/message`，为 `turn/end` 补上最后进入的步骤，将旧版失败事实映射为当前结构化错误，把 `disposed` 折叠为带 `disposed` 原因的已中止轮次，并用仅供持久化导入使用的 `{ kind: 'legacy' }` 原因表示粗粒度中止记录，因为无法获得其调用方。

-协调器会把该投影应用于 `load`、`inspect`、接管、HMR 前缀比较和 `readFrom`。可寻址的 `readFrom` 通常只读取后缀；如果后缀包含需要更早步骤或替换标识的旧版事件，协调器会先加载并规范化完整前缀，再返回所请求的 seq 范围。

 导入器不会合成 inbox splice。恢复后的 react-loop 重构前 agent 从空的待处理列表开始，这与基线运行时无法持久化待处理 inbox 工作的行为一致。已存储产物仍然仅追加，后续事件使用当前格式。

 Every `goal/changed` notification creates a checkpoint obligation. The driver awaits `ctx.sessions.flush(session)` before reserving work, then checks for a newer mutation, agent lifecycle change, or competing prompt. Turn-end flush failure is reported by the existing `agent/error` notification after `turn/end`; the driver finds that exact closed turn even when a concurrent one-shot injection appended a later turn, associates the failure with the exact attempt, and disarms before the next idle decision.
 
-Broad cancellation previously exposed only its effects after queues were cleared or the request aborted. The public agent vocabulary now includes observe-only `agent/cancel-requested(agent, reason)`. The concrete loop emits it for effective cancellation before either action; fused notification containment means a broken listener cannot veto cancellation. The goal driver uses this edge to clear its reservation before the loop destroys the queued-work evidence. When that reservation is a queued or admitted goal attempt, cancellation durably pauses the goal; when cancellation belongs to unrelated human work with no goal attempt, it only removes process-local activation. If the pause mutation throws, the driver falls back to disarming rather than allowing cancelled automatic work to restart.
+Broad cancellation clears pending inbox work and aborts the active loop phase. The goal driver follows the reserved message through inbox claim/discard events and the durable aborted turn ending. Because a turn now opens before its initial claim, cancellation can close a claimed no-step attempt; the driver marks that attempt cancelled and lets the following idle edge pause the goal, just as it does for an admitted attempt. Cancellation with no matching goal attempt only removes process-local activation. If the pause mutation throws, the driver falls back to disarming rather than allowing cancelled automatic work to restart.
