 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.

 每次 `goal/changed` 通知都会产生一个检查点义务。驱动器在预留工作前等待 `ctx.sessions.flush(session)`，随后检查是否出现了更新的变更、agent 生命周期变化或竞争提示词。轮次结束时的 flush 失败会在 `turn/end` 之后通过现有 `agent/error` 通知报告；即使并发的一次性注入已追加后续轮次，驱动器仍会找到该精确的已关闭轮次，把失败关联到精确尝试，并在下一次空闲决策前解除激活。
 
-广义取消此前只在队列已清除或请求已中止后暴露结果。公共 agent 词汇现在新增只观察的 `agent/cancel-requested(agent, reason)`。具体循环仅在取消有效时发出该事件，并且发生在清除队列和中止步骤之前；融合通知会隔离失败，因此损坏的监听器不能否决取消。目标驱动器利用该边沿在循环销毁排队工作证据前清除预留。若该预留是排队中或已接纳的目标尝试，取消会持久暂停目标；若取消属于没有目标尝试的无关人类工作，则只移除进程内激活态。若暂停变更抛错，驱动器会回退到解除激活，避免已取消的自动工作重新启动。
+广义取消会清除待处理 inbox 工作，并中止活跃 loop 阶段。目标驱动器通过 inbox 的领取／丢弃事件和持久的 aborted 轮次结束来跟踪预留消息。由于轮次现在会在首次领取前打开，取消可以关闭已领取的无步骤尝试；驱动器会把该尝试标记为已取消，并让随后的 idle 边沿暂停目标，与已准入尝试的处理方式相同。没有匹配目标尝试的取消只会移除进程内激活态。若暂停变更抛错，驱动器会回退到解除激活，避免已取消的自动工作重新启动。
