 ### Bug Fixes
 
+- fix: |Frontend| 修复 `/open_api/settings` 未返回 `domains` 数组时前端设置初始化直接调用 `map()` 报 `undefined` 错误的问题，统一按空数组兜底处理
+
 ### Improvements
 
 - refactor: |Worker| 拆分 `mails_api/index.ts` 与 `admin_api/index.ts`，入口只负责挂路由，业务拆到各自的 `*_api.ts` 文件（`mails_crud.ts` / `new_address.ts` / `parsed_mail_api.ts` / `address_api.ts` / `address_sender_api.ts` / `sendbox_api.ts` / `statistics_api.ts` / `account_settings_api.ts`），保持路径与行为不变

 ### Bug Fixes
 
+- fix: |Frontend| Fix the frontend settings bootstrap throwing an `undefined` error when `/open_api/settings` does not return a `domains` array by normalizing the field to an empty array before mapping it
+
 ### Improvements
 
 - refactor: |Worker| Split `mails_api/index.ts` and `admin_api/index.ts` so the index files only wire routes. Business logic moved into dedicated `*_api.ts` files (`mails_crud.ts` / `new_address.ts` / `parsed_mail_api.ts` / `address_api.ts` / `address_sender_api.ts` / `sendbox_api.ts` / `statistics_api.ts` / `account_settings_api.ts`).
