+## BUG-600 | 新用户保存账户资料返回 `PATCH /api/account` 500
+
+- 状态：resolved
+- 首次发现：2026-09-09
+- 最近更新：2026-09-09
+- 影响面：`PATCH /api/account`、staging 自托管 PostgreSQL、首次称呼/出生资料保存
+- 用户现象：新账号登录后保存称呼或出生资料，接口返回 `500 {"error":"暂时无法保存账户资料"}`。
+- 触发条件：self-hosted 新用户已有 trigger 创建的 `profiles` 行，前端 `persistProfile` 提交默认 `ayanamsa`。
+- 根因：`20260903010000_profile_ayanamsa.sql` 只把 `ayanamsa` 的 `UPDATE` 授给 `authenticated`。账户 PATCH 走 `service_role`；PostgreSQL 对未授权列返回 `42501 permission denied for table profiles`。该错误不含 `column`，现有缺列回退不会去掉 `ayanamsa`，因此首次保存直接 500。无档案 INSERT 不受影响，所以已有 trigger 建档的新用户会踩中。
+- 修复：新增迁移为 `service_role` 补齐 `ayanamsa` 的列级 `SELECT / INSERT / UPDATE`。
+- 验证：本地 PostgreSQL 在补授权前，含 `ayanamsa` 的 `service_role` UPDATE 返回 `42501`，去掉该列后 UPDATE 成功；补授权后含 `ayanamsa` 的 UPDATE 返回一行。`frontend/tests/profile-persistence.test.ts` 锁定新旧迁移的授权差。
+- 防复发：账户 PATCH 新增列必须同时授予 `authenticated` 自助保存和 `service_role` 并发读写；缺列回退不得把 table 级 `42501` 当成可忽略的缺列。
+- 相关记录：BUG-039、BUG-005
+- 复发自：BUG-039（全球地点列漏授 service_role 的同类权限缺口）
+- 修复版本：迁移 `20260909010000`，待发布
