+## BUG-076 | 完整出生资料已保存但权威档案状态为空
+
+- 状态：resolved
+- 首次发现：2026-07-26
+- 最近更新：2026-07-26
+- 影响面：账户出生资料保存、星盘库同步、`POST /api/consult` 服务端资料校验
+- 用户现象：出生日期、家人确认的具体时间、地点、坐标和时区都已填写，星盘库副本也显示 `birthTimeStatus: reported`，但咨询仍返回“暂时无法核对完整出生资料”。
+- 触发条件：首次创建 `profiles` 行，或既有合法出生声明的 `birth_time_status` 为空且用户原样重新保存。
+- 根因：分钟校正主链合并时把 BUG-018 的首次档案派生状态分支退回为 `{}`；共享 helper 又只在声明字段发生变化时写 `reported`，导致空状态行原样重存也无法自愈。`chart_profiles.profile` 只是星盘库 JSON 副本，不是咨询接口采用的权威出生资料。
+- 修复：账户路由统一调用共享状态派生 helper；新档案和合法声明空状态均原子写入 `reported`，确认分钟继续禁止被普通资料编辑覆盖；增加前向迁移，仅回填没有 active/candidate/case 应用结果且声明满足来源规则的空状态行。
+- 验证：账户 helper 回归覆盖新档案、空状态原样重存、候选失效和 confirmed 保护；迁移契约锁定安全过滤条件，并要求生产迁移工作流上传和应用各一次。
+- 防复发：服务端权威 `profiles` 的声明和状态必须同写；星盘库 JSON 不得作为咨询真值，历史空状态只能通过受约束前向迁移修复。
+- 相关记录：BUG-018、BUG-073
