固定预设的别名方法自带 `target` 与 `wakeup`；其已有标识的 `UserMessage` 会携带角色、内容与 provenance。编辑替换消息内容时，其 `MessageId` 保持稳定；外层 `InboxItemId` 则在 `agent/inbox/enqueue`、`agent/inbox/update` 及终态 dequeue 或 discard 之间标识同一次入队。注入绕过两个 FIFO，从不出现在这些事件中。
|
||||
每个待处理入队项就是其 `UserMessage`；`MessageId` 是唯一标识。`Inbox.append`、`prepend`、`replace`、`remove`、`clear`、`splice` 与 `claim` 会记录规范化的持久 `agent/inbox/spliced` 变更，并拒绝重复的待处理 id。`replace(messageId, newMessage)` 与 `remove(messageId)` 通过 `MessageId` 跨两份列表定位待处理消息；替换可以改变标识，并先将旧消息作为 discarded 发布，再将新消息作为 inserted 发布。普通删除和 `clear()` 都表示取消。`claim(target)` 通过无 outcome 的纯删除 splice 移除拟进入步骤的批次——全部 `next-step` 输入，外加轮次边界上的一条 `next-turn` 消息——且不发出 discarded 通知；循环另行逐条发出 claimed 通知。UI 投影等整体队列消费方通过持久 splice 重建 `nextTurn` 与 `nextStep`，而跟踪单条消息的消费方使用精确的 `agent/inbox/inserted`、`claimed` 与 `discarded` 通知。
