 - 根因：两层。其一，`finish_reason=length` 与超时中断后的半截正文仍走 `run.completed` → `complete_consultation_response`，公开回执故意不含 `modelFinishReason`，界面无法区分正常结束与夹断。其二，咨询 `agent.stream` 未设可见输出预算，也未关闭 Flash 默认 thinking；隐藏推理与可见正文共用 `max_tokens`，更容易在标题中途 `length` 停住。`AGENT_TIMEOUT_MS = 110_000` 与路由 `maxDuration = 120` 仍可能在组答阶段掐流，旧逻辑同样把已发出的半截当成功。
 - 修复：可见正文在 `length` 结束，或超时/中止时已有输出，改为 `run.failed` / `answer_truncated`，保留已流出文本，账务走 `cancel`。咨询流设置 `maxOutputTokens = 8192`，并对当前供应商与 `openai` 兼容键关闭 thinking。客户端保存半截助手消息并提示未完成、不会扣点，不再要求 `run.completed` 才落盘。

 - 修复：咨询与纠正共用 `agentGenerationSettings`（8192 可见 token，thinking disabled）。纠正在 `finish_reason=length` 时走 `answer_truncated`、不扣点、不把半截写入成功 Turn；客户端保留已流出正文并提示未完成。等待态改为公开工具进度（正在比较候选时间等）和 8 秒后的已用时，不展示模型思维链。

+## BUG-345 | 生时纠正把工具重试自述当成回答，且 kind 在 schema 里是自由字符串
+
+- 状态：resolved
+- 首次发现：2026-08-21
+- 最近更新：2026-08-21
+- 影响面：`POST /api/rectification/agent`、`runV9AgentTurn`、证据工具 `proposedKind`/`domain` schema、生时纠正对话
+- 用户现象：用户补了一条升学经历后，结算气泡里是英文工具重试自述（大意：proposedKind 被拒、education 不是合法 kind、改用 education_start），没有中文跟进问句。棋盘已推进，说明计分跑过，失败的是用户可见正文。
+- 触发条件：用户给出升学类经历，模型把 `missing_evidence_categories` 里的领域名 `education` 当成 `proposedKind` 调用证据工具。
+- 根因：与 BUG-278 / BUG-277 同类。`proposedKind` 与 `domain` 在 Zod schema 里是自由字符串，白名单只在 `execute` 的 `isEvidenceKind()` 里；模型在 JSON schema 里看不到 `education_start`。被拒后把重试过程写进 `text-delta`。纠正 runner 立刻把每个 `text-delta` 发成 `answer.delta`，没有咨询路径那种契约门。BUG-340 关闭 provider thinking 后，过程自述更容易落到正文通道。
+- 修复：证据 kind/domain 改为枚举，模型在调用前能看到 `education_start`。工具失败未恢复成功前的正文、以及纯英文过程自述，不得进入 `answer.delta`。中文思维链走独立的 `thinking.delta`（来自 `reasoning-delta` 或契约未绿的中文片段）；英文过程自述丢弃。纠正打开 provider thinking。界面灰色「思考过程」，有正文后默认折叠。
+- 验证：`frontend/tests/rectification-v10-tool-contract.test.ts` 拒绝 `proposedKind: "education"`；`frontend/tests/rectification-v9-stream.test.ts` 英文重试自述不得出现在公共流，用户只拿到中文回答；思维链映射与折叠 UI 的源码合同。
+- 防复发：模型必须遵守的词汇写在 schema 枚举里，不要只写在 execute。`answer.delta` 不得承载工具重试自述。思维链必须是独立事件类型。`thinking.delta` 不得写入 run_phase 表。
+- 相关记录：BUG-277、BUG-278、BUG-340、BUG-346

+## BUG-346 | 普通咨询未打开思维链通道，灰色折叠 UI 只在生时纠正生效
+
+- 状态：resolved
+- 首次发现：2026-08-21
+- 最近更新：2026-08-21
+- 影响面：`POST /api/consult`、`streamAgentResponse`、咨询页 `ChatMessageRow`
+- 用户现象：生时纠正已有灰色「思考过程」、正文出来后折叠；普通咨询仍无思维链。
+- 触发条件：网页个人咨询 / 无分钟百科 / 声明窗口咨询。
+- 根因：BUG-305 / BUG-340 为保住可见 token 预算，把咨询 `consultationGenerationSettings` 固定为 thinking disabled，并丢弃 `reasoning-*`。BUG-345 只给纠正打开独立 `thinking.delta` 与折叠 UI。
+- 修复：咨询同样启用 provider thinking，8192 可见预算不变。`reasoning-delta` 经中文清洗后发 `thinking.delta`；契约未绿的 `text-delta` 仍按 BUG-277 丢弃，不升格为思维链。咨询页把 `thinkingText` 接到共用 `ChatMessageRow`，有正文后默认折叠。会话落盘不保存思维链。
+- 验证：`frontend/tests/consultation-agentic-runtime.test.ts` 中文 reasoning 进 thinking 通道、英文过程自述不进正文；`consultation-workflow-contract.test.ts` 锁定 `thinking: "enabled"`；`chat-stream-layout.test.ts` 锁定咨询页与折叠 UI。
+- 防复发：咨询与纠正的思维链必须是 `thinking.delta`，不得混进 `answer.delta`。BUG-277 的契约前正文仍须丢弃。打开 thinking 不得降低 8192 可见预算，`finish_reason=length` 仍不得当完成。
