+## BUG-194 | 生时校正焦点已写入却被前端误报为未完成
+
+- 状态：resolved（本地候选，待 forward migration、staging 发布与登录态业务验收）
+- 首次发现：2026-08-15
+- 最近更新：2026-08-15
+- 影响面：V10 生时校正 opening/message 回合的 conversation focus 持久化、运行完成状态、刷新后的 Activity receipt。
+- 用户现象：Agent 已正常提出首个校正问题，但界面同时显示“设置对话焦点未完成，当前进度已保留”；刷新后失败步骤又可能从执行凭证中消失。
+- 触发条件：`set_agentic_rectification_conversation_focus` 成功插入记录后返回精简字段，而 TypeScript 工具层按完整 focus row 解析；或 set-focus 真失败后，runner 仍允许已有回答文本进入 completed 路径。
+- 根因：已部署 RPC 的创建返回值只有 `focus_id/status/idempotent`，与 `parseConversationFocus` 要求的 `id/case_id/question_id/intent/...` 合同不一致，导致成功写入后抛出 `invalid_focus`。同时 turn completion 没有把 set-focus 的最终失败状态作为阻断条件，旧 receipt 也只聚合 completed tools，造成实时与刷新后的失败状态不一致。
+- 修复：新增 forward-only migration，使创建和幂等分支统一返回完整 `focus` row 与 `idempotent`；set-focus 最终失败时 turn fail closed 为 retryable、不得发送完成回答或结算；turn receipt 按选定 attempt 聚合每个工具最新 terminal 状态并公开安全的 `tool_activities`，客户端使用同一 reducer 恢复 failed tool 与 methods。
+- 验证：聚焦回归覆盖 RPC 返回合同、失败后不得 completed、同 attempt 重试成功、receipt attempt 隔离、failed tool 持久化及刷新前后 Activity 一致性；与初始化、Case 和 migration 回归合并运行 203 passed、0 failed。远端 migration 尚未应用，仍需 staging 登录态验证最终 NDJSON、持久化 turn/receipt 与免费 opening 计费不变量。
+- 防复发：数据库 RPC 返回结构必须与 TypeScript parser 共用合同测试；提出用户可见主问题前必须成功持久化对应 focus；完成凭证不得只记录成功工具或从 Agent 文本反推执行状态。

+## BUG-195 | 新建生时校正错误继承已采用时间和用户误差范围
+
+- 状态：resolved（本地候选，待 staging 发布与登录态业务验收）
+- 首次发现：2026-08-15
+- 最近更新：2026-08-15
+- 影响面：初始化出生时间采集、`homepage/new` 生时校正 Case 基线与候选搜索范围、历史 Session 恢复。
+- 用户现象：用户再次新建校正时，系统可能以上一次采用的分钟而不是最初填报时间为中心，并继续继承旧的前后误差；初始化页面还要求用户选择误差分钟或大致时段。
+- 触发条件：Profile 同时存在 `reported_birth_time`、历史 `active_birth_time` 和 uncertainty，或只有 period/unknown 声明时创建 fresh Case。
+- 根因：fresh Case 的范围推导优先使用 `active_birth_time`，再直接读取 Profile uncertainty；初始化模型把用户声明误差和引擎搜索窗口混为同一字段，并允许用 period 或全天范围代替具体初始时间。
+- 修复：初始化 UI 只采集一个具体 `reported_birth_time`，不再提供误差分钟、大致时段、范围线索或跳过入口；新填报的准确时间保存为 `reported + 0/0`，不自动宣称引擎 confirmed。`homepage/new` 只查询和使用 `reported_birth_time`，忽略历史 active minute、uncertainty 与 period；没有合法 reported time 时在调用创建 RPC 前以 `profile_incomplete` fail closed。Case 扫描所需的可移动窗口改为独立的服务器执行策略，目前以填报时间为中心使用前后 15 分钟，不再伪装成用户声明；`intent=session` 继续恢复历史 Case 自身冻结的 baseline/range。
+- 验证：回归覆盖新初始化只展示单一时间输入、`0/0` 持久化但不确认、旧 uncertainty 不影响 fresh range、旧 active minute 不进入 baseline、period/unknown/无具体时间 legacy profile 不得新建、失败前不调用 RPC，以及 session 恢复不读取当前 Profile；与 Focus、receipt 和 migration 回归合并运行 203 passed、0 failed。
+- 防复发：`reported_birth_time` 是 fresh Case 唯一用户时间基线；`active_birth_time` 只表示已采用的当前排盘时间，不能反向改写新校正起点；用户声明字段、服务器搜索策略与最终 confirmed truth 必须保持分层。
