fix(web): isolate rectification answers from tool-step planning text

Mastra intermediate text-delta was published as answer.delta, then set-focus domain errors reset the attempt and replayed evidence. Publish only the terminal no-tool step, persist the next probe on the server, and ground batch quotes in the source turn. Co-authored-by: Cursor <cursoragent@cursor.com>

+## BUG-368 | 工具步骤英文规划被当成回答，set-focus 失败又整轮重放证据
+
+- 状态：resolved（本地修复，待提交与发布）
+- 首次发现：2026-08-24
+- 最近更新：2026-08-24
+- 影响面：`POST /api/rectification/agent`、Mastra `fullStream` 步骤边界、`rectification-set-focus`、Evidence Batch、用户消息 origin、推荐问题
+- 用户现象：用户说「2020年4月开始实习、6月转正、10月离职」后，界面先刷出残缺英文（`Let me`、`_probe`、`_gain`）。`rectification-set-focus` 连续失败后整轮重跑，已成功的证据再提交一次，只落地实习、另外两条被引文拒。随后聊天里出现一条用户从未输入的「2002 年发生什么了」。
+- 触发条件：自由文本经历回合；Agent 在调用工具前输出规划文本；`set-focus` 因重复探针或零信息增益被拒；失败运行的推荐问题被写进历史。
+- 根因：三组独立回归。(1) 禁止 `thinking.delta` 后，把每个 step 的 `text-delta` 都公开成 `answer.delta`，工具前规划变成用户正文；再对碎片做英文过滤，句子被剪成残片。(2) `compare-candidates` 已算出下一问，仍让模型自己调 `set-focus`；确定性校验失败后 `attempt.reset` 重放已成功的 Evidence 写入。(3) 未完成运行的 suggestion / 角色映射把「2002 年发生什么了」写成 user 消息。2002 不是引擎从 2020 算出来的。
+- 修复：按 step 缓冲，只发布无工具且 `stop`/`length` 的终端文本；`reasoning-delta` 不下发。Agent 工具列表去掉 `set-focus`，由 compare/read-case 在服务端持久化 `open_question`。`duplicate_focus` 等域错误不整轮重试，相同工具参数最多一次。用户消息记录 `origin`/`clientActionId`/`content_hash`。Evidence quote 用源消息 offset，按条返回 created/already_exists/quote_mismatch。推荐问题只在 `run.completed` 后解析，纠正 UI 仍无 suggestion chip。不改已哈希 Skill `10.0.11`。
+- 验证：`frontend/tests/rectification-step-answer.test.ts`、`frontend/tests/rectification-v9-stream.test.ts`、`frontend/tests/rectification-server-focus.test.ts`、`frontend/tests/rectification-evidence-quote.test.ts`、`frontend/tests/rectification-agentic-entry.test.ts`、`frontend/tests/rectification-v10-tool-contract.test.ts`。
+- 防复发：禁止把含工具调用的 step 的 `text-delta` 发给浏览器。禁止把 `thinking.delta` 改名为 `answer.delta`。禁止模型驱动 `set-focus`。禁止对 `duplicate_focus` / `quote_mismatch` / `zero_information_gain` 做 `attempt.reset`。禁止未完成运行解析或自动提交 suggestion。禁止模型改写 Evidence quote。
+- 相关记录：BUG-345、BUG-354、BUG-357、BUG-367
+- 复发自：BUG-367（关掉公开 `thinking.delta` 后，中间 step 的 `text-delta` 被整段当成回答）
+- 修复版本：待发布
