+## BUG-175 | V9 明确事件被强制要求额外二次确认
+
+- 状态：resolved（本地候选）
+- 首次发现：2026-08-12
+- 最近更新：2026-08-12
+- 影响面：V9 生时校正事件证据写入、Agent 访谈连续性与候选评分输入。
+- 用户现象：用户已经明确说出“2016 年 9 月上大学”后，Agent 仍要求再回答一次“对/确认”，否则事件不进入评分账本。
+- 触发条件：当前轮包含日期、主体和事件语义均明确的新事件，Agent 完成 `rectification-propose-evidence` 后继续按旧 Prompt/Skill 等待下一轮确认。
+- 根因：Prompt、工具描述、Skill 文档与 TypeScript 状态机把“confirmed 只能由服务器确认路径产生”错误等同于“必须额外等待一轮用户同意”；同时 `scorableEvidence()` 又把 `pending_confirmation` 纳入正式评分，导致确认语义与评分边界不一致。数据库确认 RPC 实际已支持 `draft -> confirmed`。
+- 修复：当前轮主动、明确、单一且无歧义的用户事件由 Agent 在同一个 run 内依次调用 propose 与服务器 confirm；只有模糊、冲突、修订或需要补充原文外信息时追问。评分输入统一只接受 `confirmed` 且有日期的证据，保留 quote grounding、Case/Turn ownership、幂等与 append-only 修订链。
+- 验证：回归测试覆盖同轮 `propose -> confirm` 工具顺序、`draft -> confirmed` 合法迁移、Prompt 不再要求重复确认，以及 pending/draft 不进入正式评分。
+- 防复发：服务器确认路径与额外对话轮次必须分开建模；任何 pending 状态不得隐式参与正式候选评分。

+## BUG-176 | V9 普通 Turn 的 Agent 回复在刷新后消失
+
+- 状态：resolved（本地候选）
+- 首次发现：2026-08-12
+- 最近更新：2026-08-12
+- 影响面：V9 生时校正历史消息、持久化 Activity 与 Agent 下一轮上下文。
+- 用户现象：事件提交后当轮可以看到 Agent 回复和 Activity，但刷新或重新进入 Case 后只剩用户事件；opening Agent 消息仍可显示。
+- 触发条件：一条物理 `agentic_rectification_turns` 记录同时保存非空 `user_message` 与 `assistant_message`。
+- 根因：`get_agentic_rectification_case_dossier()` 把每条物理 Turn 只投影成一条逻辑消息，并用 `coalesce(user_message, assistant_message)` 优先返回用户文本，导致同一行已持久化的 Agent 回复和 receipt 关联在恢复 API 中丢失。
+- 修复：新增向前业务迁移，将每条物理 Turn 通过 lateral values 展开为按 user、assistant 排序的最多两条逻辑消息；保留同一真实 Turn ID，使 assistant 消息继续读取对应 Activity receipt。
+- 验证：迁移契约测试锁定双消息展开、空消息过滤、顺序、迁移唯一性和禁止复制到 identity migration tree；staging 需继续验证 Case GET、页面刷新、下一轮上下文及计费不变量。
+- 防复发：持久化行与对话消息不是一对一时，恢复投影必须显式展开全部逻辑消息，不得用 `coalesce` 静默舍弃其中一侧。

+## BUG-177 | 首页生时校正被未完成 Session 强制劫持，无法新建独立校正
+
+- 状态：resolved（staging 发布与真实环境验收以本次发布记录为准）
+- 首次发现：2026-08-12
+- 最近更新：2026-08-12
+- 影响面：首页生时校正卡片、`POST /api/rectification/cases/open`、V9 Case 并发约束
+- 用户现象：账户存在任意未完成的生时校正时，从首页点击“生时校正”会直接回到旧 Session；用户无法保留旧记录并另开一段校正。
+- 触发条件：存在 `draft`、`collecting_evidence`、`candidate_ready`、`candidate_accepted`、`needs_rebaseline` 或 `paused` Case 后点击首页生时校正卡片。
+- 根因：V9 初始设计把首页 `homepage` intent 定义为 resume-or-create，并用 `agentic_rectification_cases_one_resumable_per_user` 部分唯一索引和 `active_case_conflict` 强制每用户最多一个 resumable Case；首页 UI 又据 entry summary 显示“继续上次校正”。该安全约束错误扩大成产品限制。
+- 修复：首页入口始终作为显式创建动作；新增向前迁移 `20260813040000_allow_parallel_rectification_cases.sql`，删除每用户单 resumable 唯一索引并重定义 open RPC，使 `homepage`/`new` 创建独立 Case + Session，`session` 仍按精确 Session 恢复；requestId 幂等与同用户 advisory lock 保留。首页有未完成记录时明确提示可从左侧历史继续，但主 CTA 仍是新建。
+- 验证：入口、Case service、迁移静态合同等聚焦测试共 119 项，113 通过、0 失败；6 项真实 PostgreSQL 测试因本机 Docker 不可用跳过（测试已覆盖不同 requestId 新建多个 resumable Case、同 requestId 幂等和精确 Session 恢复）。目标 ESLint 与 `git diff --check` 通过；全量 TypeScript 检查仅命中仓库既有的 `dayjs` 缺失及无关测试类型错误。
+- 防复发：首页“新建”和历史“继续”必须使用不同 intent；不得用“存在 resumable Case”改变首页主 CTA 或阻止新 Case；同一 requestId 重试只能返回同一 Case。
+- 相关记录：BUG-163

 - 修改事实必须生成 superseding revision，**不得覆盖历史**。
 - 日期精度真实保留：只说年份就保留 `year`，不得诱导用户编造月份/日期。
 - 禁止模型补充月份、日期、原因、主动/被动、人物关系等原文没有的信息。
