 ## Current Status
 
-**Phase 2 done.** 用户详情页 + 反馈管理 + 订阅管理 + CSV 导出 已完成。Phase 1c 数据看板真实数据仍延后。Next: Phase 3 — UGC 审核.
+**Phase 3 done.** UGC 审核 + 举报处理 + 运营配置 + 多管理员支持 已完成。Phase 1c 数据看板真实数据仍延后。所有计划内功能开发完毕，后续按需迭代。
 
 Development follows the phased roadmap in [dev-spec.md](./dev-spec.md) §九.

 ## Key Patterns
 
 - **Routing**: React Router v7 library mode (`createBrowserRouter` + `RouterProvider`). Routes defined in `App.tsx`. Root layout (`routes/__root.tsx`) handles auth guard — redirects to `/login` when not authenticated.
 - **Development order**: Follow [dev-spec.md](./dev-spec.md) §九 (Phase roadmap).
-- **Auth flow**: Login page → POST `/admin/auth/login` with token → receive admin JWT → store in auth-store → attach as `Authorization: Bearer <jwt>` on all subsequent requests
+- **Auth flow**: Login page supports Token and username/password login. Token: POST `/admin/auth/login` → receive JWT. Password: POST `/admin/auth/login` with credentials → receive JWT. Both modes fall back to offline mode when backend is unavailable (stores a `offline_` prefixed token locally). JWT stored in auth-store → attached as `Authorization: Bearer <jwt>` on all subsequent requests.
 - **API client**: All admin API calls go through `lib/api-client.ts` (ky v2). Uses `baseUrl` + `prefix: "/admin"`. Auto-attaches auth header. 401 responses trigger logout + redirect to `/login`.
 - **Data tables**: TanStack Table v8 headless + shadcn/ui styled components in `components/data-table/`
 - **Forms**: React Hook Form + Zod validation for all admin forms
