 - 触发条件：collect 焦点下用户提供带年月经历，模型只调 `rectification-read-case` 后按格式写「记下了」，不调 `rectification-record-evidence-batch` / `rectification-set-focus`。
 - 根因：路由分类结果没传给运行器，收尾只要正文非空就 `completeAttempt`，不看有没有公开写工具。客户端把旧消息上的同 `focus_id` 当成问题仍在显示，缺口不补主持人问题行。
 - 修复：路由把 `expectedWrite` 设为 `"evidence" | "none" | "unknown"` 传进运行器；`provide_new_evidence` 或 `answer_current_focus` + `has_new_dated_event` → `"evidence"`。分类器 null/出错重试一次，仍失败则 `"unknown"` 且守卫 fail-open，**不用年份正则或关键词兜底**。无焦点的 `message` 路径也跑同一分类器。无写入的「记下了」第一次 `evidence_not_written` 可重试（零写工具，不进 `RETRYABLE_ERROR_CODES`）；第二次主持人正文「这件我还没记上。请再说一次大概年月和发生的事。」，`answer.host_fallback`，不结算计费。`liveQuestionOnMessages` 只认最后一条 settled 助手消息。
-- 验证：`frontend/tests/rectification-unwritten-evidence.test.ts`，以及 host-fallback / spoken-collect / agentic-entry / turn-intent-classifier / agent-voice-copy-contract。
+- 验证：`frontend/tests/rectification-unwritten-evidence.test.ts`，以及 host-fallback / spoken-collect / agentic-entry / turn-intent-classifier / agent-voice-copy-contract。`rectification-v9-agent.test.ts` 的 persist 三句夹具必须带 completed batch，否则 635 会把它收成未写入（Gitea run 2545）。
 - 防复发：有公开写工具 completed 不得重试（BUG-186）；兜底正文不得由宿主复述用户原话冒充「记下了」；旧消息同 `focus_id` 不得挡住主持人问题行。
 - 相关记录：BUG-186、BUG-278、BUG-359、BUG-449、BUG-633
 - 复发自：BUG-633（只补了 batch 已完成且无正文，没补正文声称记下了但 batch 没跑）

 ### 既有断言改动
 
 - `rectification-v9-stream.test.ts` empty_stream 二次成功正文：原值「记下了这件事。」/ 新值「先继续核对。」；原因：BUG-635 把无写入的「记下了」收口成 `evidence_not_written`，该用例只锁 empty_stream 重试。
+- `rectification-v9-agent.test.ts` `evidence persist keeps the first sentence when the model writes three`：断言未改。原夹具 read-case 后直接写三句「记下了」、无 batch / 新夹具 batch + set-focus completed 后再写那三句 / 原因：Gitea `Independent Staging Quality Gate` run 2545 全文套件 3082/3083，该条被 635 收口成「这件我还没记上」；用例名是 persist，夹具必须真写入。
