- v0.20.2: 超管+团管可改用户名(5 步矩阵 + UTF-8 字节计长度)
  + 团管观察者标记(全局资产视图,不见 ¥)
  + UsersPage/TeamMembersPage 操作列收敛到「编辑」modal
  + 用户名旁角色 badge + TeamAdminLayout 加铃铛/主题切换

迁移: 0020(api_prompt) + 0015(audit choice user_username_update) + 0016(is_observer)

+| I | Safari 自适应根因 | `6b13cff` | AdminLayout `100dvh` + `min-height: 0` + 4 个 admin 页 `.pagination padding-bottom: 8px` + ProfilePage 同款 dvh fallback |
+
+### 关键根因/设计要点
+
+- **批次 I 不是 padding 补丁**:Safari 桌面 `100vh` 算的是含工具栏的 layout viewport,不是用户实际可见区;Flex `overflow-y: auto` 没有 `min-height: 0` 形同虚设。三件套 `100dvh + min-height: 0 + padding-bottom` 才是根因解
+- **批次 G 权限服务端硬校验**:前端按钮 `canResetPasswordFor(m)` 只是 UX,后端 view 5 步逐层判 (同团队 / 不能改自己 / 主管须超管 / 副管只有主管能改 / 合法)
+- **批次 D MySQL 严格模式守门**:Notification 所有 CharField 都加 `default=''`(memory `feedback_mysql_default`)
+- **批次 D 用 `AppNotification` 类型名**:避免和浏览器 Web API `Notification` 全局类冲突

+详见 `docs/todo/v0.20.1-完成报告.md`。

+
+## 二、批次详情
+
+### 批次 A — 主管理员撤销 bug + 文档标完成 ✅
+- **bug**: TeamsPage L825 主管理员 badge 无 onClick,管理员设了某成员为主管后撤不掉,只能后台改 DB
+- **修法**: 前端补 onClick + window.confirm + 调 `setMemberRole(false)`,后端 `admin_team_member_role_view` 早就支持收 `is_team_admin=false` 时同时清 `is_team_owner`
+- **文档**: 项目总览待办 P3#1 主题切换 / P3#7 副管角色 / P2#2 飞书告警 三项标 ✅(均为之前完成漏更文档)
+
+### 批次 B — 视频封面帧前端补全 ✅
+- **背景**: 后端 `tasks.py:_handle_completed` L109-111 早就用 ffmpeg 提取首帧上传 TOS 存 `record.thumbnail_url`,但只在 `_serialize_task`(生成页)返回。admin/team/profile 三个 records view 都没回传
+- **后端**: admin_records / team_records / profile_records 各加 `'thumbnail_url': r.thumbnail_url or ''`
+- **前端**:
+  - `AdminRecord` 类型加 `thumbnail_url?: string`
+  - 三处 `<video>` 加 `poster={thumbnailUrl ? rewriteTosUrl(...) : undefined}`(RecordDetailModal / VideoDetailModal / GenerationCard)
+  - 效果:卡片首屏立即显示首帧海报(几十 KB),不再等视频 metadata 加载完才有视觉
+- **改动文件**: 5
+
+### 批次 C — api_prompt 永久留痕 + 调试折叠区 ✅
+- **背景**: v0.19.2 上线了 prompt @素材→「图片N」转换。客服/财务复盘投诉时需查实际传给火山的 prompt
+- **后端**:
+  - `GenerationRecord.api_prompt` TextField 新字段 + migration `0021_add_api_prompt`
+  - `video_generate_view` 计算完 `_format_prompt_for_ark` 后立即 save api_prompt(即使 create_task 抛错也保留)
+  - admin_records / team_records view 回传 api_prompt
+- **前端**:
+  - `AdminRecord` 加 `api_prompt?: string`
+  - RecordDetailModal 详情弹窗右侧底部加"调试信息(开发/客服参考)"折叠区:
+    - 默认 ▸ 收起,小灰字
+    - 点开 ▾ 展开,仅当 `api_prompt && api_prompt !== prompt` 显示"实际发给火山"等宽字 box(老记录 api_prompt='' 时不显示)
+    - 火山 Task ID + 复制按钮
+    - 失败任务才显示原始错误 raw_error
+- **改动文件**: 5
+
+### 批次 D — 站内通知系统(最大块) ✅
+- **后端 — 新 app `apps.notifications`**:
+  - `Notification` model: type/title/content/link_url/is_read,索引 (recipient, is_read, -created_at)
+  - 4 个 endpoint:
+    - `GET /api/v1/notifications/` (列表 + 总未读数,unread_only/page/page_size)
+    - `GET /api/v1/notifications/unread-count` (轻量,前端 60s 轮询)
+    - `PATCH /api/v1/notifications/<id>/read`
+    - `POST /api/v1/notifications/read-all`
+  - 严格守 user 隔离:所有查询都 `filter(recipient=request.user)`
+  - INSTALLED_APPS 注册 + urls.py include + admin.py 注册
+  - migration `0001_initial` 应用成功
+  - **MySQL 严格模式**:所有 CharField 显式加 `default=''`(避踩 memory `feedback_mysql_default`)
+- **后端 — anomaly_detector 集成**:
+  - `_RULE_LABELS` / `_team_admin_recipients()` / `_notify_user_disabled()` / `_notify_team_disabled()` helper
+  - `process_anomalies` 里 `_disable_user/_disable_team` 之后调对应 notify
+  - 接收人 = 同团队的主管+副管(`is_team_admin OR is_team_owner`)
+  - `bulk_create` 一次写多条
+  - try/except 保护:通知失败不阻断封禁主流程(只 log warning)
+- **前端**:
+  - types: `AppNotification` / `NotificationListResponse`(用 App 前缀避开浏览器 Web API `Notification` 冲突)
+  - lib/api.ts: `notificationApi` (list / getUnreadCount / markRead / markAllRead)
+  - store/notification.ts: Zustand store 乐观更新(markRead 先动 UI 再发请求)
+  - pages/NotificationsPage.tsx: 标题 + 全部标记已读按钮 + 未读蓝点 + 相对时间 + 点击跳 link_url + 分页 + 空状态
+  - App.tsx: `/notifications` 路由(ProtectedRoute 不限 role,成员/团管/超管都能进)
+  - Sidebar.tsx(用户 76px):铃铛 SVG + 红点(`var(--color-danger)`) + 60s 轮询 + visibilitychange 立即刷新
+  - **AdminLayout.tsx(超管 220px)**:同步加铃铛 — sub-agent 一开始只加了用户侧 sidebar,通过 v0.20.1-smoke 测试发现 admin 路由无铃铛,补全
+- **改动文件**: 12 个(新建 9 + 修改 3)
+- **后端 curl 验证全过**: list / unread-count / PATCH read / POST read-all 都正常,user 隔离 OK
+
+### 批次 G — 团管重置成员密码 ✅
+- **权限矩阵(plan §G,服务端硬校验)**:
+  | 操作者 | 可重置 | 不可重置 |
+  |--------|--------|----------|
+  | 主管(`is_team_owner=True`) | 同团队**副管 + 成员** | 其他主管 / 自己 |
+  | 副管(`is_team_admin=True && !owner`) | 同团队**成员** | 副管 / 主管 / 自己 |
+- **后端**:
+  - 新 view `team_reset_member_password_view` POST `/api/v1/team/members/<id>/reset-password`
+  - permission `IsTeamAdmin`(覆盖主管+副管)+ 服务端逐层判断 5 步
+  - 生成 8 位随机密码(`secrets.choice(ascii_letters+digits)`)+ `must_change_password=True`
+  - `log_admin_action` audit 留痕
+- **前端**:
+  - `teamApi.resetMemberPassword(memberId)` → 返回 `{ new_password, ... }`
+  - TeamMembersPage `canResetPasswordFor(m)` helper 同权限矩阵
+  - 成员行 actions 加"重置密码"按钮(只在 canReset 为 true 时显示)
+  - 结果 modal 用 monospace 大字 + 浅灰底显示密码 + ⚠"关闭后无法再次查看" + 复制按钮
+- **后端 6 项 curl 测试全通过**:
+  - T1 主管→副管(200 ✓)/ T2 主管→成员(200 ✓)/ T3 主管→自己(400 ✓)
+  - T4 副管→主管(403"主管须超管"✓)/ T5 副管→成员(200 ✓)/ T6 副管→副管(403"只有主管能重置副管"✓)
+
+### 批次 H — TeamAssetsPage 重新编辑 prompt 丢失 ✅
+- **根因 4 层叠加**:
+  1. TeamAssetsPage 没传 `onReEdit` prop 给 VideoDetailModal → 走 modal 内部 fallback
+  2. fallback 只 `setPrompt(task.prompt)`,没设 `editorHtml`
+  3. PromptInput 是 contenteditable,渲染依据是 `editorHtml` 不是 `prompt`
+  4. `assetVideoToTask` 把 `editorHtml` 显式置 `''` → fallback 拿到的就是空串
+- **修法**: 跟 `store/generation.ts:reEdit` 对齐,用 `useInputBarStore.setState` 一次性批量灌入,关键补 `editorHtml: task.editorHtml || task.prompt || ''`,让 PromptInput 渲染 + rebuildMentionSpans 走完整路径
+- **影响**: 团管 `/team/assets` reEdit ✓ / 超管 `/admin/assets` 同上 ✓ / 用户 `/user-assets` reEdit(走 generation.ts 的另一条路)不受影响
+
+### 批次 I — Safari 自适应根因修法 ✅
+- **现象**: Mac Safari + 14寸,/admin/records 翻页按钮永远在屏幕外,拖动能看到内容超出但滚到底也看不见
+- **根因三个叠加**:
+  1. `100vh` 在 Safari 桌面端不可靠 — 算的是含工具栏/书签栏的 layout viewport,不是实际可见的 visual viewport
+  2. Flex `overflow` 经典 bug — `.content { flex: 1; overflow-y: auto }` 没加 `min-height: 0`,flex 子默认 `min-height: auto` 跟随内容撑开,overflow-y: auto 形同虚设
+  3. 翻页按钮无 `padding-bottom`,贴边视觉不舒服
+- **修法(根因三件套,不是 padding 兜底)**:
+  1. `AdminLayout.module.css .layout` — `height: 100dvh` + fallback `100vh`(Dynamic Viewport Height,Safari 17+/Chrome 108+/FF 101+ 支持)
+  2. `AdminLayout.module.css .content` — 加 `min-height: 0`,让 flex 子元素正确 shrink
+  3. 4 个 admin 页 `.pagination` 加 `padding-bottom: 8px`(RecordsPage / UsersPage / LoginRecordsPage / AuditLogsPage)
+  4. `ProfilePage.module.css .page` 同样 `100vh` 模式 → 加 `100dvh` fallback,防同款 bug 在用户端复现
+

+
+## 三、测试结果
+
+### 基线对比
+
+| 测试 | 基线 | v0.20.1 | 状态 |
+|------|------|---------|------|
+| `npx tsc -b` | 0 error | 0 error | ✓ |
+| `npx vitest run` | 71 fail / 162 pass | 71 fail / 162 pass | ✓ 无新增回归 |
+| `node test/v2-smoke.mjs` | 25 / 25 | 25 / 25 | ✓ |
+| `node test/modal-interaction.mjs` | 8 / 8 | 8 / 8 | ✓ |
+| `node test/v0.20.1-smoke.mjs` | 新增 | **11 / 11** | ✓ |
+| `manage.py check` | clean | clean | ✓ |
+
+### v0.20.1 smoke 覆盖项
+
+1. Sidebar 消息中心铃铛可见(AdminLayout 220px)
+2. 铃铛红点显示(有未读时)
+3. 点铃铛跳 `/notifications`
+4. 消息中心标题渲染
+5. AdminLayout 高度 ≈ viewport(100dvh 生效)
+6. `.content { min-height: 0 }` 生效
+7. 详情弹窗"调试信息"折叠按钮存在
+8. 调试信息默认收起(▸)
+9. 调试信息可展开(▾)
+10. video poster 已挂载(从 TOS CDN)
+11. Teams 页加载(主管 badge 交互移交手测)
+
+### 后端 endpoint curl 验证
+
+- 通知 4 endpoint:list / unread-count / PATCH read / POST read-all 全过 ✓
+- 团管重置密码 6 项权限 case(主/副 × 改主/改副/改成员/改自己)全过 ✓
+
+---
+
+## 四、本地状态
+
+- **分支**: dev
+- **commit 数**: 7 个功能 commit + 1 个 docs 收尾(下一步)
+- **未 push**: 等用户授权
+- **DB migration**: `generation/0021_add_api_prompt` + `notifications/0001_initial` 本地已 apply
+
+---
+
+## 五、待用户做
+
+1. **本地手测** — 浏览器跑一遍 7 个批次的可见效果(建议优先测 D 通知 + G 重置密码 + I 14寸 Safari):
+   - admin/admin123 测后台(D / I)
+   - tudou 团管账号测 G 重置密码 + 验权限矩阵
+   - Mac Safari + 笔记本测 I(本地开发 Mac Safari 不一定能复现,实测需要测试服)
+2. **授权 push** — 我等你"可以 push"指令,然后跑 `ALLOW_PUSH=1 git push origin dev`(memory `feedback_must_confirm_push`)
+3. **CI 部署后** — 测试服 K8s 自动滚新版本,跟你确认线上观察 OK 后,可以考虑 cherry-pick 到 master
+
+---
+
+## 六、风险与已知限制
+
+| 风险 | 缓解 |
+|------|------|
+| `api_prompt` 历史记录为空 | 详情弹窗只在 `api_prompt && api_prompt !== prompt` 才显示那栏,不影响 |
+| 视频 `thumbnail_url` 历史记录为空 | `poster={thumbnailUrl ? ... : undefined}`,行为同改前 |
+| Notification 表数据膨胀 | created_at 加 index;后续考虑 90 天软清理 |
+| 重置密码后操作员不慎刷新 | modal 关闭后无法再次查看密码(已在 UI 用 ⚠ 提示)|
+| Safari < 17 无 `100dvh` | fallback 到 `100vh`,行为同改前(不变好也不变差) |
+| 站内通知不实时(60s 轮询) | 公测前不上 WebSocket,60s 对自动封禁告警通知够用 |
+
+---
+
+## 七、跨项目踩坑记录(自动加 memory)
+
+无新踩坑。本批次所有改动都遵循已有 memory(feedback_mysql_default / feedback_verify_before_deliver / feedback_must_confirm_push 等)。

+
+---
+
+## 批次 B — 视频封面帧 前端补全(~1h)
+
+### 发现
+后端 `tasks.py:_handle_completed` L109-111 已经在生成完成后:
+1. ffmpeg 提取首帧
+2. 上传 TOS 到 `thumbnails/` 路径
+3. 存到 `GenerationRecord.thumbnail_url`
+
+**前端没用这个字段** → 列表/卡片还在用 `<video src={result_url}>` 直接加载视频。
+
+### 改动
+
+**后端(3 处加 1 行)**:
+- `admin_records_view` 返回字段加 `thumbnail_url`
+- `team_records_view` 同上
+- `_serialize_task`(生成页用) — 检查是否有,有就加
+
+**前端**:
+- `types/index.ts`:
+  - `AdminRecord` 加 `thumbnail_url?: string`
+  - `BackendTask` 加 `thumbnail_url?: string`
+  - `GenerationTask` 加 `thumbnailUrl?: string`
+- `store/generation.ts` `backendToFrontend` 转换函数加 `thumbnailUrl: t.thumbnail_url`
+- `GenerationCard.tsx`:
+  - 列表/小预览用 `<img src={rewriteTosUrl(task.thumbnailUrl)}>` 替代 `<video src={task.resultUrl}>`
+  - hover/click 详情时才换 `<video>` 加载真实视频
+- `RecordDetailModal.tsx`:
+  - `<video poster={rewriteTosUrl(r.thumbnail_url)} src={...}>` 显示首帧
+- `VideoDetailModal.tsx`(资产页弹窗) — 同 poster
+
+### 验收
+- 浅色/深色页面 OK
+- 网络面板看:列表打开时只下载 thumbnail(几十 KB)不下载 video(几 MB)
+- 点详情才加载真实视频
+
+---
+
+## 批次 C — api_prompt 永久留痕 + 调试信息折叠区(方案 A,~30min)
+
+### 改动
+
+**后端**:
+- `GenerationRecord` 加字段 `api_prompt = models.TextField(blank=True, default='', verbose_name='实际发给火山的提示词')`
+- migration `0021_add_api_prompt.py`
+- `video_generate_view` 调 `create_task` 前 `record.api_prompt = api_prompt; record.save(update_fields=['api_prompt'])`
+- `admin_records_view` + `team_records_view` 返回 `api_prompt`
+
+**前端**:
+- `types/index.ts` `AdminRecord` 加 `api_prompt?: string`
+- `RecordDetailModal.tsx` 右侧信息区底部加**默认折叠的"调试信息"区域**:
+  ```
+  ...(提示词区)...
+
+  ▸ 调试信息(开发/客服参考)     ← 默认收起,小灰字
+  ```
+  点开后:
+  ```
+  ▾ 调试信息(开发/客服参考)
+    实际发给火山(@素材名被自动转换为「图片N」):
+    ┌──────────────────────────────────┐

+- 实现:`useState<boolean>(false)` 控制展开,onClick 切换
+- 仅在 `api_prompt && api_prompt !== prompt` 时显示"实际发给火山"那栏,否则只有 task_id
+
+### 验收
+- 默认看不到这块(收起)
+- 点开展示 api_prompt + task id + 失败原因等内部信息
+- 历史记录 api_prompt 空时不显示那栏
+- 不破坏现有 modal 视觉,平时用户察觉不到
+
+---
+
+## 批次 D — 站内通知系统(~4h)
+
+### 改动
+
+**后端 model**:
+```python
+class Notification(models.Model):
+    TYPE_CHOICES = [
+        ('anomaly_disabled_user', '账号因异常被自动封禁'),
+        ('anomaly_disabled_team', '团队因异常被自动封禁'),
+        ('quota_warning', '额度即将耗尽'),

+        indexes = [models.Index(fields=['recipient', 'is_read', '-created_at'])]
+```
+
+migration `0022_notification.py`
+
+**后端 API**:
+- `GET /api/v1/notifications?unread_only=false&page=1&page_size=20` — 列表(分页) + 未读数
+- `PATCH /api/v1/notifications/<id>/read` — 标单条已读
+- `POST /api/v1/notifications/read-all` — 标全部已读
+
+**后端 触发点**:
+- `anomaly_detector.py` 自动封禁逻辑里调 `Notification.objects.create(recipient=team_admin, type='anomaly_disabled_user', title=..., content=...)`
+- 团队管理员收到下属被封禁的通知
+
+**前端**:
+- `web/src/types/index.ts` 加 `Notification` 类型
+- `web/src/store/notification.ts` 新建 — Zustand store(getUnreadCount/list/markRead/markAllRead)
+- `web/src/components/Sidebar.tsx` 顶部加铃铛 SVG(团管 + admin 都显示)+ 未读红点
+- 点击展开下拉面板 / 跳通知中心页(后者更体面)
+- 新页面 `web/src/pages/NotificationsPage.tsx` 列表 + "全部已读"按钮 + 行点击跳 link_url
+- App.tsx 路由 `/notifications`
+- 启动时 + 焦点回到 tab 时 fetch unread count
+- 不做实时 push(WebSocket 太重),做 60s 轮询足够
+
+### 验收
+- 自动封禁动作触发后,被影响用户的团管立即(60s 内)在铃铛看到红点
+- 点击通知跳对应安全日志 / 用户管理页

+## 批次 E — ❌ 砍掉,以后再做
+
+手机号验证码登录跟运维确认后**暂缓**。代码、阿里云短信模板申请都不做。
+
+---
+
+## 批次 G — 团管重置成员密码(~1h)
+
+### 权限矩阵(关键)
+
+| 操作者 | 可改 | 不可改 |
+|---|---|---|
+| 主管(`is_team_owner=true`) | 同团队**副管 + 成员** | 其他主管 |
+| 副管(`is_team_admin=true && is_team_owner=false`) | 同团队**成员** | 副管 + 主管 |
+
+### 改动
+
+**后端**:
+- `views.py` 新增 `team_reset_member_password_view`(`POST /api/v1/team/members/<id>/reset-password`)
+  - 权限:`IsTeamAdmin`
+  - 校验链:
+    ```python
+    target = team.members.get(id=member_id)
+    operator = request.user
+    if target.team_id != operator.team_id:
+        return 403 '不在同一团队'
+    if target.is_team_owner:
+        return 403 '主管理员密码须由超管重置'
+    if target.is_team_admin and not operator.is_team_owner:
+        return 403 '只有主管理员能重置副管理员密码'
+    # 此处 target 要么是副管(operator 是主管)要么是普通成员 — 都可以改
+    ```
+  - 复用 admin_reset_password_view 密码重置逻辑(随机 8 位密码 + `must_change_password=True` + 返回新密码)
+  - log_admin_action 记录审计日志
+- `urls.py` 加路由
+- 不动 model / migration
+
+**前端**:
+- `web/src/lib/api.ts` `teamApi` 加 `resetMemberPassword(memberId)` POST
+- `web/src/pages/TeamMembersPage.tsx` 成员行 actions 按当前登录用户角色 + 目标成员角色判断:
+  - 我是主管(`useAuthStore.user.is_team_owner`)→ 对副管 + 成员行显示"重置密码"按钮
+  - 我是副管 → 只对成员行显示
+  - 点击 → confirm "重置 XXX 的密码?(成员下次登录需修改)" → 调 API → 弹窗显示新密码 + 复制按钮
+  - Toast 提示成功
+
+### 验收
+- 主管登录 → 团队成员管理 → 副管 + 成员行有"重置密码"按钮,其他主管行没有
+- 副管登录 → 只有成员行有按钮,副管/主管行没有
+- 后端硬校验:即使前端绕过(直接 curl),副管调 reset 副管 → 403
+- 重置后该成员下次登录强制改密(must_change_password=true 走 ForceChangePasswordModal)

+
+## 批次 H — TeamAssetsPage 重新编辑 prompt 丢失(~10min)
+
+### 现状
+团管在 `/team/assets` 点视频 → VideoDetailModal → "重新编辑"按钮 → 跳转 `/app` 生成页。
+**Bug**:图片资源回到了 references 区,但 prompt 文本框是空的。
+
+### 根因
+1. `TeamAssetsPage.tsx` 没传 `onReEdit` 给 VideoDetailModal → 走 VideoDetailModal 内部 fallback(L214-240)
+2. fallback 调 `store.setPrompt(task.prompt)` 但**没设 `editorHtml`**
+3. PromptInput 是 contenteditable + 渲染 `editorHtml`,editorHtml 空 → 编辑器空
+4. `assetVideoToTask` L55 把 `editorHtml: ''` 显式置空 → fallback 兜底 `task.editorHtml || task.prompt` 时拿到空字符串
+
+### 改动
+
+**VideoDetailModal.tsx handleReEdit fallback(L214-240)**:
+跟 `generation.ts:reEdit` 对齐,完整设置 InputBar 所有相关 state:
+```js
+useInputBarStore.setState({
+  prompt: task.prompt || '',
+  editorHtml: task.editorHtml || task.prompt || '',  // ← 关键补
+  mode: (task.mode as ...) || 'universal',
+  model: (task.model as ...) || 'seedance_2.0',
+  aspectRatio: (task.aspectRatio as ...) || '16:9',
+  duration: task.duration || ...,
+  resolution: task.resolution || '720p',
+  references: refs,  // 已有逻辑
+  assetMentions: task.assetMentions || [],
+});
+```
+
+### 验收
+- 团管 /team/assets → 任意视频 → "重新编辑" → 跳 /app → **prompt 文本框有内容** + 图片在 references 区
+- 用户端 /user-assets 走 reEdit 不受影响(原本 work)
+- 生成页 /app 内 reEdit 不受影响(原本 work)

+
+## 批次 I — Safari 自适应根因修复(翻页按钮被截 + 防其他页面 viewport bug)(~15min)
+
+### 现象
+- 用户:Mac Safari + 14寸笔记本
+- 路径:`/admin/records` 翻页按钮永远在屏幕外
+- 拖动能看到内容超出,但**滚动到底也看不见翻页按钮**
+
+### 根因(三个叠加)
+
+**根因 1 — `100vh` 在 Safari 不可靠**
+`AdminLayout.module.css` `.layout { height: 100vh }` 在桌面 Safari 算的是**含工具栏/书签栏的 layout viewport**,不是用户实际能看到的区域(visual viewport)。在小屏(14寸)+ 多个 UI bar 显示时,`.layout` 实际比可见区域高一截 → 底部被 UI bar 盖住。
+
+**根因 2 — Flex `overflow` 经典 bug**
+`.content { flex: 1; overflow-y: auto }` 没有 `min-height: 0`。flex 子元素默认 `min-height: auto`(根据内容撑开),Safari/Chrome 都不让 flex 父级约束子元素高度 → 子元素超出内容时,`overflow-y: auto` 形同虚设,`.content` 不滚动,底部按钮被父级 `.layout { overflow: hidden }` 截掉。
+
+**根因 3 — 按钮无 padding-bottom**
+就算前两个修了,翻页按钮紧贴容器边缘视觉也不舒服。
+
+### 改动(根因修复 + polish)
+
+**1. `AdminLayout.module.css` `.layout` — 用 dvh 替代 vh**:
+```css
+.layout {
+  display: flex;
+  height: 100vh;       /* fallback for Safari < 17 */
+  height: 100dvh;      /* Dynamic Viewport Height - 自动减去 toolbar/书签栏 */
+  overflow: hidden;
+  ...
+}
+```
+
+**2. `AdminLayout.module.css` `.content` — 加 min-height: 0 修 flex overflow**:
+```css
+.content {
+  flex: 1;
+  overflow-y: auto;
+  min-height: 0;       /* ★ 关键:让 flex 子元素正确 shrink + 触发 overflow-y */
+  padding: 24px 32px 32px;
+}
+```
+
+**3. 各 admin 页 `.pagination` — 加底部缓冲**:
+- `RecordsPage.module.css`
+- `UsersPage.module.css`
+- `TeamsPage.module.css`
+- `AdminAssetsPage.module.css`
+- `LoginRecordsPage.module.css`
+- `AuditLogsPage.module.css`
+
+```css
+.pagination {
+  margin-top: 16px;
+  padding-bottom: 8px;
+}
+```
+
+**4. 检查 `VideoGenerationPage.module.css` `.layout` 也用 100vh,顺手改 dvh(团管 / 个人路由)**:
+```css
+.layout {
+  ...
+  height: 100vh;
+  height: 100dvh;
+}
+```
+
+**5. `index.css` `html, body, #root { height: 100% }`** — 已经是 100% 不依赖 vh,不动。
+
+### 验收
+- **14寸笔记本 Safari** → `/admin/records` 翻页按钮**可见可点**
+- **生成页** 滚动正常,InputBar 不会被 Safari 工具栏盖
+- **桌面大屏** 不受影响(dvh = vh = 视口)
+- **老 Safari (<17)** fallback 100vh 行为跟之前一样(不变好但不变差)
+- **Chrome / Firefox** dvh 都支持,正常
+
+### 为什么这个修法比"加 padding 兜底"更对
+
+之前考虑的"加 padding-bottom 48px"是治标 — 假设 viewport 不会再变,加缓冲就行。但实际 Safari 在用户切换 zoom / 显示书签栏时,实际可见区域会变,固定 padding 仍会被切。`100dvh` 是浏览器动态计算可见区域,**永远准**。`min-height: 0` 修的是 flex 容器自身的滚动机制,**根因层面解决**。

+
+## Phase 0 — 现状事实表（plan agent 读完代码后确认）
+
+### Backend
+
+| Item | Truth |
+|---|---|
+| accounts 最高 migration | `0014_set_existing_admins_as_owners.py` → 下一个 **0015** |
+| `User.role` property | `'super_admin'` / `'team_admin'` / `'member'` (`accounts/models.py:74-80`) |
+| `AdminAuditLog.ACTION_CHOICES` | 13 actions 末尾 `('user_password_reset', '重置用户密码')` (`accounts/models.py:84-99`) |
+| `UserSerializer` fields | `id, username, email, is_staff, is_team_admin, is_team_owner, role, team_name, must_change_password` (`accounts/serializers.py:14`) |
+| `admin_user_detail_view` | GET only (`views.py:1535`) |
+| `team_member_detail_view` | GET only (`views.py:2494`) |
+| **照抄 5 步权限矩阵** | `team_reset_member_password_view` at `views.py:2683-2743` |
+| **admin 账号保护** | `admin_user_status_view:1675` (`if user.username == 'admin': return 403`) |
+| Username validator | Django `UnicodeUsernameValidator` 允许 `[\w.@+-]` Unicode → 中文 OK |
+| 三个资产 endpoint | `views.py:2912 / 2961 / 3001` 全用 `[IsSuperAdmin]` |
+| `log_admin_action` 签名 | `(request, action, target_type, target_id=None, target_name='', before=None, after=None)` (`accounts/models.py:243`) |
+
+### Frontend
+
+| Item | Truth |
+|---|---|
+| 内联编辑模板 | `TeamsPage.tsx:445-491` — `<span style={{display:'inline-flex', gap:6, alignItems:'center', flexWrap:'nowrap'}}>` + 保存/取消按 `whiteSpace:'nowrap'`（**没有可复用 InlineEdit 组件，就地写**） |
+| `User` type (`types/index.ts:89`) | 已有 `is_team_owner?: boolean`，需加 `is_observer` |
+| `ProtectedRoute` props | 已有 `requireAdmin / requireTeamAdmin / requireTeamMember`，需加 `requireAdminOrObserver` |
+| `AdminLayout` nav | hardcoded `navItems` at top |
+| `TeamAdminLayout` | 4 项 dashboard/members/records/assets（团队的） |
+| UsersPage row | L228-271；username at L237 (`<button styles.usernameLink>`) |
+| TeamMembersPage row | L174-231；username at L182（无 button） |
+
+### AdminAssetsPage 的 ¥ 出现位置（精确）
+
+1. `AdminAssetsPage.tsx:8` — `formatCost` helper
+2. **L158** — 总费用统计卡 value
+3. **L174** — team accordion badge
+4. **L195** — member accordion badge
+5. **L238** — no-team badge
+6. **VideoDetailModal.tsx:548-554** — token + ¥ block（已确认 `assetVideoToTask` 不填 `tokensConsumed/costAmount`，**已经不渲染**，无需改）
+
+---
+
+## Phase A — 修改用户名（commit 1）
+
+### 关键决策
+
+| 决策 | 选择 | 理由 |
+|---|---|---|
+| `admin_user_detail` 加 PUT 还是新 endpoint | **新建 `admin_user_username_update_view`** | 1) detail GET 是聚合查询不能污染 2) 项目惯例：`/quota`、`/status`、`/reset-password` 都是专项写 endpoint 3) 审计/限流粒度好控 |
+| 复用什么 inline edit | **就地按 TeamsPage:445-491 模板写**（不抽组件） | 项目无 `<InlineEdit>` 组件、本次不抽避免范围蔓延 |
+| 5 步矩阵 | **照抄 `team_reset_member_password_view`** | 1) 同团队 2) 不能改自己 3) 不能改主管 4) 副管不能改副管 5) 走到合法 |
+
+### Backend 改动
+
+**文件 1：`backend/apps/accounts/models.py`** — `ACTION_CHOICES` 末尾加
+
+```python

+
+```bash
+cd backend && python manage.py makemigrations accounts -n add_username_update_audit_action

+```
+
+**文件 4：`backend/apps/generation/urls.py`** — 加 2 条 route（位置：reset-password 那两行之后）
+
+```python
+path('admin/users/<int:user_id>/username', views.admin_user_username_update_view, name='admin_user_username_update'),
+path('team/members/<int:member_id>/username', views.team_member_username_update_view, name='team_member_username_update'),
+```
+
+### Frontend 改动
+
+**文件 5：`web/src/lib/api.ts`** — 加 2 方法
+
+```typescript
+// adminApi 段（resetUserPassword 之后）
+updateUserUsername: (userId: number, username: string) =>
+  api.patch<{ user_id: number; username: string }>(`/admin/users/${userId}/username`, { username }),
+
+// teamApi 段（resetMemberPassword 之后）
+updateMemberUsername: (memberId: number, username: string) =>
+  api.patch<{ user_id: number; username: string }>(`/team/members/${memberId}/username`, { username }),
+```
+
+**文件 6：`web/src/pages/UsersPage.tsx`** — 用户名 cell 加内联编辑（L237 附近）
+
+state：`const [editingUsernameId, setEditingUsernameId] = useState<number|null>(null); const [editingUsernameValue, setEditingUsernameValue] = useState('');`
+
+显示态：保留现有 `<button>` 用户名链接，旁边加铅笔小图标按钮触发编辑
+
+编辑态：`<input value={editingUsernameValue} />` + 保存按钮 + 取消按钮（容器 `display:'inline-flex', gap:6, alignItems:'center', flexWrap:'nowrap'`，**保存/取消按钮 `whiteSpace:'nowrap'` 强制不换行**）
+
+**前端不显示编辑按钮的情况**：`u.username === 'admin'`（admin 行只读）
+
+**文件 7：`web/src/pages/TeamMembersPage.tsx`** — 用户名 cell 同上（L182 附近）
+
+加 helper：
+
+```typescript
+function canEditUsernameFor(m: TeamMember, op: User | null): boolean {
+  if (!op || !m) return false;
+  if (m.id === op.id) return false;
+  if (m.username === 'admin') return false;
+  if (m.is_team_owner) return false;
+  if (m.is_team_admin && !op.is_team_owner) return false;
+  return true;
+}
+```
+
+前端只在 `canEditUsernameFor` 返回 true 时显示编辑按钮（后端永远是真相）。
+
+Toast：成功 `已更新用户名为「xxx」`，失败显示 `err.response?.data?.error || '操作失败'`

+| # | Scenario | 期望 |
+|---|---|---|
+| A1 | 超管把 `tudou` → `豆豆`（中文） | 200, audit log `user_username_update` |
+| A2 | 超管改 `admin` | 403 `不能修改超级管理员的用户名` |
+| A3 | 超管设新名 = 已存在 | 400 `该用户名已被占用` |
+| A4 | 超管设新名 = `ab`（2 字） | 400 `长度需 3-20` |
+| A5 | 团管（主管）改自己 | 400 `不能修改自己的用户名` |
+| A6 | 副管改另一个副管 | 403 `只有主管理员能修改副管理员` |
+| A7 | 团管 A 提交团队 B 的 member_id | 404 `成员不存在` |
+| A8 | 主管改副管 → 成员 | 200，前端列表实时刷新 |
+
+---
+
+## Phase B — 观察者标记（commit 2）
+
+### 关键决策
+
+| 决策 | 选择 | 理由 |
+|---|---|---|
+| 「设观察者」入口放哪 | **`UsersPage.tsx` 用户行操作列** | 1) 编辑用户角色属性最自然在用户管理 2) TeamsPage 团队详情入口太深 3) 已有 reset密码/编辑/禁用 3 个 row-level 操作，加这个语义一致 |
+| 校验目标 | **后端硬拒绝非团管 + 拒绝超管自己** | 避免数据库里有半生效状态 |
+
+### Backend 改动
+
+**文件 1：`backend/apps/accounts/models.py`**
+
+```python
+# User 类内（is_team_owner 那行之后）
+is_observer = models.BooleanField(default=False, verbose_name='观察者（仅对团管生效，可看全局资产）')
+
+# ACTION_CHOICES 加（在 A 加的 user_username_update 之后）
+('user_observer_toggle', '切换观察者标记'),
+```
+
+**文件 2：迁移**
+
+```bash
+cd backend && python manage.py makemigrations accounts -n user_is_observer
+cd backend && python manage.py migrate
+```
+
+**MySQL 严格模式提醒** — grep 验证：
+
+```bash
+grep -rn "User(" backend/apps/ | grep "save()" | grep -v migrations
+```
+
+如有裸 `User(**data).save()` 调用点需审；BooleanField default=False 无 NULL 风险。
+
+**文件 3：`backend/apps/accounts/serializers.py`**
+
+```python
+fields = ('id', 'username', 'email', 'is_staff', 'is_team_admin', 'is_team_owner',
+          'is_observer',  # ← 新增
+          'role', 'team_name', 'must_change_password')
+```
+
+**文件 4：`backend/apps/accounts/permissions.py`** — 新 class
+
+```python
+class IsSuperAdminOrObserver(BasePermission):
+    """超级管理员 或 团队管理员且 is_observer=True"""
+    def has_permission(self, request, view):
+        u = request.user
+        if not (u and u.is_authenticated):
+            return False
+        if u.is_staff and u.team is None:
+            return True
+        if u.is_team_admin and u.team is not None and getattr(u, 'is_observer', False):
+            return True
+        return False
+```
+
+**文件 5：`backend/apps/generation/views.py`**
+
+5a. 3 个资产 endpoint 权限替换（`views.py:2912 / 2961 / 3001`）：
+
+```python
+@permission_classes([IsSuperAdminOrObserver])  # 替换 IsSuperAdmin
+```
+
+并把 `IsSuperAdminOrObserver` 加入 import 行：
+
+```python
+from apps.accounts.permissions import IsSuperAdmin, IsTeamAdmin, IsTeamMember, IsSuperAdminOrObserver
+```
+
+5b. 新 endpoint：
+
+```python
+@api_view(['PATCH'])
+@permission_classes([IsSuperAdmin])
+def admin_user_observer_toggle_view(request, user_id):
+    """PATCH /api/v1/admin/users/<id>/observer — 仅超管，把团管标记为观察者。"""
+    try:
+        target = User.objects.get(id=user_id)
+    except User.DoesNotExist:
+        return Response({'error': '用户不存在'}, status=status.HTTP_404_NOT_FOUND)
+
+    if not (target.is_team_admin and target.team_id is not None):
+        return Response({'error': '观察者标记只能给团队管理员'}, status=status.HTTP_400_BAD_REQUEST)
+    if target.is_staff and target.team_id is None:
+        return Response({'error': '超级管理员无需设观察者'}, status=status.HTTP_400_BAD_REQUEST)
+
+    is_observer = request.data.get('is_observer')
+    if is_observer is None:
+        return Response({'error': '请提供 is_observer 参数'}, status=status.HTTP_400_BAD_REQUEST)
+    new_val = bool(is_observer)
+    old_val = target.is_observer
+    if old_val == new_val:
+        return Response({'user_id': target.id, 'username': target.username, 'is_observer': new_val})
+    target.is_observer = new_val
+    target.save(update_fields=['is_observer'])
+
+    log_admin_action(request, 'user_observer_toggle', 'user',
+                     target_id=target.id, target_name=target.username,
+                     before={'is_observer': old_val},
+                     after={'is_observer': new_val})
+    return Response({'user_id': target.id, 'username': target.username, 'is_observer': new_val})
+```
+
+**文件 6：`backend/apps/generation/urls.py`**
+
+```python
+path('admin/users/<int:user_id>/observer', views.admin_user_observer_toggle_view, name='admin_user_observer_toggle'),
+```
+
+### Frontend 改动
+
+**文件 7：`web/src/types/index.ts`** — 3 处加 `is_observer`
+
+```typescript
+// L89 User
+is_observer?: boolean;
+
+// L164 附近 AdminUser
+is_observer?: boolean;
+
+// TeamMember（如有）也加，便于团管页面识别
+```
+
+**文件 8：`web/src/lib/api.ts`**
+
+```typescript
+toggleUserObserver: (userId: number, isObserver: boolean) =>
+  api.patch<{ user_id: number; username: string; is_observer: boolean }>(
+    `/admin/users/${userId}/observer`, { is_observer: isObserver }),
+```
+
+**文件 9：`web/src/components/ProtectedRoute.tsx`** — 加 prop + 智能 fallback
+
+```typescript
+interface Props {
+  children: React.ReactNode;
+  requireAdmin?: boolean;
+  requireAdminOrObserver?: boolean;  // ← 新
+  requireTeamAdmin?: boolean;
+  requireTeamMember?: boolean;
+}
+
+// 在 requireAdmin 判断段加智能 fallback
+if (requireAdmin && user?.role !== 'super_admin') {
+  if (user?.role === 'team_admin') return <Navigate to="/team/dashboard" replace />;
+  return <Navigate to="/app" replace />;
+}
+
+if (requireAdminOrObserver) {
+  const isAdmin = user?.role === 'super_admin';
+  const isObserverTeamAdmin = user?.role === 'team_admin' && user?.is_observer;
+  if (!isAdmin && !isObserverTeamAdmin) {
+    if (user?.role === 'team_admin') return <Navigate to="/team/dashboard" replace />;
+    return <Navigate to="/app" replace />;
+  }
+}
+```
+
+**文件 10：`web/src/App.tsx`** — 路由分级守卫
+
+```tsx
+<Route
+  path="/admin"
+  element={
+    <ProtectedRoute requireAdminOrObserver>
+      <AdminLayout />
+    </ProtectedRoute>
+  }
+>
+  <Route index element={<RoleAwareIndexRedirect />} />  {/* 见下方 */}
+  <Route path="dashboard" element={<ProtectedRoute requireAdmin><DashboardPage /></ProtectedRoute>} />
+  <Route path="users" element={<ProtectedRoute requireAdmin><UsersPage /></ProtectedRoute>} />
+  {/* ... 所有其他 admin 子页面都用 requireAdmin 包 ... */}
+  <Route path="assets" element={<AdminAssetsPage />} />  {/* 父路由的 requireAdminOrObserver 已 cover */}
+</Route>
+```
+
+`RoleAwareIndexRedirect` 是小辅助组件：
+
+```tsx
+function RoleAwareIndexRedirect() {
+  const user = useAuthStore((s) => s.user);
+  if (user?.role === 'team_admin' && user?.is_observer) {
+    return <Navigate to="/admin/assets" replace />;
+  }
+  return <Navigate to="/admin/dashboard" replace />;
+}
+```
+
+**文件 11：`web/src/pages/AdminLayout.tsx`** — sidebar 按角色过滤
+
+```tsx
+const user = useAuthStore((s) => s.user);
+const isObserverOnly = user?.role === 'team_admin' && !!user?.is_observer;
+
+const visibleNavItems = isObserverOnly
+  ? navItems.filter(i => i.path === '/admin/assets')
+  : navItems;
+
+// 渲染 visibleNavItems 替代 navItems
+
+// logo 文案：isObserverOnly 时显示「观察者」替代「管理后台」
+// 「返回首页」按钮：isObserverOnly 时改跳 /team/dashboard 并改 label「返回团队管理」
+```
+
+**文件 12：`web/src/pages/TeamAdminLayout.tsx`** — sidebar 末尾加「全局资产」入口（仅观察者可见）
+
+```tsx
+const user = useAuthStore((s) => s.user);
+const isObserver = !!user?.is_observer;
+
+// 在现有 4 个 nav 之后加一个额外按钮（不在 navItems 数组中，因为跳的是不同 layout）
+{isObserver && (
+  <button className={styles.navItem} onClick={() => navigate('/admin/assets')}>
+    <GlobeIcon /> <span>全局资产</span>
+  </button>
+)}
+```
+
+**文件 13：`web/src/pages/AdminAssetsPage.tsx`** — 4 处 ¥ 条件渲染
+
+```tsx
+const user = useAuthStore((s) => s.user);
+const hideMoney = user?.role !== 'super_admin';  // observer 团管 = 非超管 = 隐藏
+
+// L158 总费用统计卡（整张条件渲染）
+{!hideMoney && (
+  <div className={styles.statCard}>
+    <div className={styles.statLabel}>总费用</div>
+    <div className={styles.statValue}>{formatCost(overview.total_seconds)}</div>
+  </div>
+)}
+
+// L174 team badge
+{!hideMoney && <span className={styles.accordionBadge}>{formatCost(team.cost_consumed ?? team.seconds_consumed)}</span>}
+
+// L195 member badge — 同 L174
+
+// L238 no-team badge — 同 L174
+```
+
+`VideoDetailModal` 不动（`assetVideoToTask` 已经不填 tokensConsumed/costAmount，¥ 行已经不渲染）。**在 `assetVideoToTask` 上方加注释**：
+
+```tsx
+// 不传 tokensConsumed/costAmount — 观察者团管隐藏 ¥ 依赖此默认行为
+```
+
+**文件 14：`web/src/pages/UsersPage.tsx`** — 行加切换按钮 + observer badge
+
+```tsx
+{u.is_team_admin && u.team_id && (
+  <button
+    className={styles.editBtn}
+    onClick={async () => {
+      try {
+        await adminApi.toggleUserObserver(u.id, !u.is_observer);
+        showToast(
+          u.is_observer
+            ? `已取消「${u.username}」的观察者标记`
+            : `已将「${u.username}」设为观察者（需该用户重新登录后生效）`
+        );
+        fetchUsers();
+      } catch (e: any) {
+        showToast(e.response?.data?.error || '操作失败');
+      }
+    }}
+  >
+    {u.is_observer ? '取消观察者' : '设为观察者'}
+  </button>
+)}
+
+// 用户名/团队 cell 后加 badge
+{u.is_observer && (
+  <span className={styles.statusBadge} style={{ background: 'var(--color-info-bg)', color: 'var(--color-info)', marginLeft: 6 }}>
+    观察者
+  </span>
+)}
+```
+
+### Phase B 验收 cases
+
+| # | Scenario | 期望 |
+|---|---|---|
+| B1 | 超管 PATCH 把 `tudou`（团管）`is_observer=true` | 200, DB 更新, audit log `user_observer_toggle` |
+| B2 | 超管对普通成员设 | 400 `观察者标记只能给团队管理员` |
+| B3 | 超管对 `admin` 自己设 | 400 `超级管理员无需设观察者` |
+| B4 | `tudou`（is_observer=true）GET `/admin/assets/overview` | 200 全局数据 |
+| B5 | `tudou`（is_observer=false）GET `/admin/assets/overview` | 403 |
+| B6 | 普通成员 `bob` GET `/admin/assets/overview` | 403 |
+| B7 | 观察者 `tudou` 登录后 `/auth/me` 返回 `is_observer: true` → sidebar 出现「全局资产」入口 | 视觉验证 |
+| B8 | 观察者打开 `/admin/assets`：3 张统计卡少 1 张，所有 badge 仅剩「N 个视频」（**无 ¥**） | 视觉验证 |
+| B9 | 观察者点视频详情：info bar 无 tokens/¥ | 视觉验证 |
+| B10 | 观察者尝试访问 `/admin/users` | 被 `requireAdmin` 拒，自动 302 到 `/team/dashboard`（团管 fallback） |
+
+---
+
+## 9 个关键风险点
+
+1. **admin 账号在 team_member 那条线也得兜底拒**（已在 view 内加 `if target.username == 'admin'`）
+2. **副管/主管判断顺序**：先 `is_team_owner` 再 `is_team_admin`（照抄 `team_reset_member_password_view:2717-2722`）
+3. **MySQL 严格模式**：`is_observer` BooleanField default=False 无风险；但需 grep 验证无裸 `User(**data).save()` 用法
+4. **JWT token 不缓存 `is_observer`**，但**前端 `auth.user.is_observer` 是登录时拉的快照** → 观察者标记切换后那个用户必须重新登录或刷新 `/auth/me` 才能在自己客户端看到「全局资产」入口。UsersPage toast 已写「需该用户重新登录后生效」
+5. **`/admin/users` 等子路由的 race**：父路由 `requireAdminOrObserver`，子页面分别用 `requireAdmin` 拦截（观察者团管根本进不去子页面渲染）
+6. **普通团管被 `requireAdmin` 拒** → 弹回 `/team/dashboard` 不是 `/app`（ProtectedRoute 智能 fallback）
+7. **迁移编号**：A=0015, B=0016（已确认 accounts 当前最高 0014）
+8. **观察者下载**：用户决策「能看就能下」→ VideoDetailModal 已有下载按钮保留不动
+9. **空白/前后空格**：已 `.strip()`；中文/特殊字符按 `UnicodeUsernameValidator` `full_clean()` 自动处理；不另加禁止
+
+---

+# 通知 / 公告整合 — 完成报告
+
+**完成日期**: 2026-05-15
+**分支**: dev(3 个 commit + plan/报告 docs)
+**push 状态**: 本地完成,等用户授权 push
+
+---
+
+## 一、改动总览
+
+| # | Commit | 简述 |
+|---|--------|------|
+| 1 | `7a503db` | feat(notification): 公告整合进 Notification — fan-out + 强弹 Modal + chip + 删 announcement_enabled 概念 |

+
+## 二、最终行为(对齐用户)
+
+1. 超管在系统设置编辑公告内容(rich text + 6 个工具按钮 + 预览)
+2. 编辑完点【**发送公告**】独立按钮 → 二次 confirm "确认发送给所有用户?发送后所有人打开页面会强制看到这条公告,无法撤回"
+3. 后端 fan-out 给**所有用户**(含 `is_active=False` 封禁用户,解封后能看到累积历史)
+4. 任意用户登录 / 打开任意路由 → `<GlobalAnnouncementGate>` 顶层组件 fetch 未读公告 → **强制弹 modal,必须看**
+5. 关闭 modal(点【我知道了】/ ✕ / 遮罩点击)= 标已读 → 不再弹
+6. 想重看 → sidebar 大铃铛 → 消息中心 → 找到那条公告点开(HTML 渲染)
+7. 消息中心列表每条带 type chip: [公告] / [安全] / [额度] / [系统] 4 色
+8. 删除右上角小喇叭、删除 `announcement_enabled` 开关(发了就强弹,无静默模式)
+
+---
+
+## 三、改动文件
+
+### 后端 (3 modified)
+- `backend/apps/notifications/models.py` — TYPE_CHOICES 加 `'announcement'`
+- `backend/apps/generation/views.py` — 新增 `admin_publish_announcement_view` + 重写 `announcement_view` / `announcement_read_view`(内部全部走 Notification 表)
+- `backend/apps/generation/urls.py` — 新路由 `POST /api/v1/admin/announcement/publish`
+
+### 前端 (7 modified + 1 new)
+- `web/src/App.tsx` — 顶层挂 `<GlobalAnnouncementGate />`
+- `web/src/components/GlobalAnnouncementGate.tsx` — **新建**,负责"任意路由检测 + 强弹 + 标已读 + 同步铃铛"
+- `web/src/components/AnnouncementModal.tsx` — 改纯展示组件(props 接 content + onClose,不自己 fetch),HTML 用 DOMPurify
+- `web/src/components/VideoGenerationPage.tsx` — 删右上角小喇叭 + 旧 AnnouncementModal 自动弹 + 旧 AnnouncementBanner import
+- `web/src/lib/api.ts` — 加 `announcementApi.publish(content)`
+- `web/src/pages/SettingsPage.tsx` — 删 announcement_enabled checkbox + 加【发送公告】按钮 + 二次 confirm
+- `web/src/pages/NotificationsPage.tsx` — 每条加 type chip + announcement HTML 渲染(DOMPurify)
+- `web/src/types/index.ts` — `NotificationType` 加 `'announcement'`
+
+### 删除 (2 files)
+- `web/src/components/AnnouncementBanner.tsx`(废弃,无引用)
+- `web/src/components/AnnouncementBanner.module.css`
+
+### 测试 + 文档 (3 new)
+- `web/test/announcement-integration-smoke.mjs` — 10 项 E2E
+- `docs/todo/通知公告整合.md` — 整合 plan v2
+- `docs/todo/通知公告整合-完成报告.md` — 本报告
+
+---
+
+## 四、关键设计决策
+
+### 1. 强弹位置:全局顶层 vs 各路由各自挂
+
+**选**:全局 `<GlobalAnnouncementGate>` 在 `App.tsx` `<Routes>` 之外。
+- 所有路由统一行为
+- 不需要每个 page 都加 `<AnnouncementModal />`
+- 跨路由切换时如果未读还在,继续弹(行为一致)
+
+### 2. fan-out 范围:含封禁用户
+
+**选**:`User.objects.all()` 而非 `filter(is_active=True)`。
+- 封禁用户解封后能看到累积的历史公告
+- bulk_create + 索引 `(recipient, is_read, -created_at)` 性能足够(150 用户 / 1 年 50 公告 = 7500 行可忽略)
+- 用户不会因为"封禁期间错过通知"而抱怨
+
+### 3. 发布触发:独立按钮 vs 整体保存
+
+**选**:独立【发送公告】按钮 + 二次 confirm,不和"保存设置"按钮共用。
+- 防误操作 — 超管改配额时不会顺带触发公告 fan-out
+- 用户明确表达"我点发就直接发了"的明确动作语义
+
+### 4. announcement_enabled 字段保留 vs 删除
+
+**选**:字段保留(QuotaConfig 不动 schema)但前端不再读。
+- 避免 migration
+- 后端发送时仍写 `announcement_enabled=True`,作为"最近一次发送过"的标记
+- 真实判断 fan-out 走的是 `Notification.is_read`,不再依赖这个 flag
+
+### 5. HTML 安全:DOMPurify 而非禁 HTML
+
+**选**:Modal 和 NotificationsPage 两处都用 `DOMPurify.sanitize(content)`。
+- 保留 HTML 富文本能力(超管可加粗/红字/链接)
+- 用 DOMPurify 防 XSS
+
+### 6. 老 endpoint 兼容
+
+**选**:`/announcement` + `/announcement/read` 保留 endpoint,内部改走 Notification 表,响应结构不变。
+- 老前端 PWA 缓存平滑过渡
+- 后续可以无痛删 endpoint(本次不删)
+
+---
+
+## 五、测试结果
+
+### 后端 curl 验证(5 项全过)
+
+| Case | 期望 | 结果 |
+|------|------|------|
+| 空内容发送 | 400 "公告内容不能为空" | ✓ |
+| HTML 发送 | 200 sent_to=N | ✓ (sent_to=21) |
+| tudou GET /announcement | 拿到那条 HTML + is_read=false + notification_id | ✓ |
+| tudou POST /announcement/read | updated≥1 | ✓ (updated=1) |
+| tudou 再 GET | enabled=false + is_read=true | ✓ |
+
+### 前端 smoke 全过
+
+| 测试 | 基线 | 整合后 | 状态 |
+|------|------|--------|------|
+| `npx tsc -b` | 0 error | 0 error | ✓ |
+| `npx vitest run` | 71 fail / 162 pass | 71 fail / 162 pass | ✓ 0 新增回归 |
+| `web/test/v2-smoke.mjs` | 25/25 | 25/25 | ✓ |
+| `web/test/modal-interaction.mjs` | 8/8 | 8/8 | ✓ |
+| `web/test/v0.20.1-smoke.mjs` | 11/11 | 11/11 | ✓ |
+| `web/test/announcement-integration-smoke.mjs` | 新增 | **10/10** | ✓ |
+
+### 新 smoke 覆盖 10 项
+
+1. 空内容发送返回 400
+2. HTML 发送成功 sent_to=N
+3. fan-out 数 = User 总数(21=21)
+4. tudou GET /announcement 拿到未读公告
+5. tudou 浏览器进 /app **自动强弹公告 modal**
+6. 关闭 modal 后 GET /announcement 返回已读
+6.1 再开页面不再弹 modal
+7. 消息中心显示 [公告] chip
+7.1 公告内容 HTML 渲染正常
+8. 全程无 console.error
+
+---
+
+## 六、边缘 case 处理
+
+| Case | 处理 |
+|------|------|
+| 超管反复编辑公告但不点【发送】 | textarea 内容只保存在本地 state,刷新页面会重置到上次发布的内容(QuotaConfig.announcement)— 接受 |
+| 超管点【发送】两次 | fan-out 两次,所有用户消息中心多两条记录 — UI 二次 confirm 防误点 |
+| 公告内容为空点【发送】 | 前端先校验 + 后端 400 兜底,双重保护 |
+| 用户在路由 A 弹 modal 没关 → 切到 B | modal 跟随全局,在 B 继续显示。关闭前任何路由都被遮住 |
+| 同时多条未读公告 | 显示最新一条;关闭后下次 visibilitychange 再 check 又拿到下一条;依次到都读完 |
+| 封禁用户公告 | 发出去时也 bulk_create 给他;封禁状态登不上来看不到,解封后能看到累积 |
+| 老前端 PWA 缓存调 `/announcement` | endpoint 响应结构兼容,平滑 |
+
+---
+
+## 七、本地状态
+
+- **分支**: dev
+- **commit 数**: 2 个功能 commit + 1 个 docs 收尾(下一步)
+- **未 push**: 等用户授权
+- **DB migration**: 无(TYPE_CHOICES 是 choices 软约束,DB schema 不变)
+
+---
+
+## 八、待用户做
+
+1. **本地手测**(可选,smoke 已覆盖关键链路)— 浏览器跑一遍:
+   - admin 系统设置写公告 → 点【发送公告】→ 二次确认 → 提示 "已发送给 N 个用户"
+   - 退出 admin → 用 tudou 登录 → 任何页面应该被 modal 挡住
+   - 点【我知道了】→ modal 关闭 + sidebar 铃铛红点同步
+   - 进消息中心 → 看到刚发的公告 + [公告] chip + HTML 渲染
+2. **授权 push** — 等"可以 push"指令,跑 `ALLOW_PUSH=1 git push origin dev`(memory `feedback_must_confirm_push`)
+3. **测试服跑通后** — 合 master 部署生产(单独授权)
+
+---
+
+## 九、风险与已知限制
+
+| 风险 | 缓解 |
+|------|------|
+| Notification 表 announcement 类条目随时间膨胀 | 现有索引 `(recipient, is_read, -created_at)` 覆盖查询;未来加 90 天软清理 |
+| 超管打开页面也会被自己刚发的公告挡 | 接受 — 超管也是用户,看一次就行;关掉就不再弹 |
+| 新注册用户看不到历史公告 | 接受 — 公告时效性强,新人不补发 |
+| HTML 内容超长 modal 滚动 | AnnouncementModal CSS 已有 max-height + overflow-y(继承自原实现)|

+**起因**:v0.20.1 消息中心(Notification)上线后跟公告(QuotaConfig.announcement)UX 重叠 — 两个铃铛、两套未读、两套入口。
+
+**目标**:统一到消息中心,公告作为 `type='announcement'` 的 Notification。
+
+**预估**:约 1.5 小时
+
+---
+
+## 一、最终行为(对齐用户)
+
+1. 超管在系统设置编辑公告内容(rich text)
+2. 编辑完点【**发送公告**】独立按钮 → fan-out 给**所有用户**(含封禁用户)
+3. 任意用户登录 / 打开任意页面 → 有未读 announcement 就**强制弹 modal,必须看**(关闭才能用页面)
+4. 关闭 = 标已读,不再弹
+5. 想重看 → sidebar 大铃铛 → 消息中心 → 找到那条公告
+6. 消息中心列表每条带 type chip([公告] / [安全] / [额度] / [系统])
+7. 删除右上角小喇叭、删除 `announcement_enabled` 开关概念(发了就强弹,无静默模式)
+
+---
+
+## 二、后端改动
+
+### 1. `apps/notifications/models.py` TYPE_CHOICES 加项
+
+```python
+TYPE_CHOICES = [
+    ('anomaly_disabled_user', '账号因异常被自动封禁'),
+    ('anomaly_disabled_team', '团队因异常被自动封禁'),
+    ('quota_warning', '额度即将耗尽'),
+    ('announcement', '系统公告'),     # 新增
+    ('system', '系统通知'),
+]
+```
+
+无 migration(CharField choices 软约束)。
+
+### 2. `apps/generation/views.py` 新 endpoint
+
+```python
+@api_view(['POST'])
+@permission_classes([IsSuperAdmin])
+def admin_publish_announcement_view(request):
+    """POST /api/v1/admin/announcement/publish — 发送公告给所有用户。
+
+    Body: { "content": "<html>...</html>" }
+    """
+    from apps.notifications.models import Notification
+    from apps.accounts.models import User as UserModel
+
+    content = (request.data.get('content') or '').strip()
+    if not content:
+        return Response({'error': '公告内容不能为空'}, status=status.HTTP_400_BAD_REQUEST)
+
+    # 把最新公告也写回 QuotaConfig.announcement 当存档(超管下次编辑时能看到上次发的)
+    config = QuotaConfig.objects.get(pk=1)
+    config.announcement = content
+    config.announcement_enabled = True  # 字段保留兼容,但前端不再读
+    config.save(update_fields=['announcement', 'announcement_enabled'])
+
+    # fan-out — 所有用户(含封禁,封禁用户解封后能看到历史)
+    user_ids = list(UserModel.objects.all().values_list('id', flat=True))
+    notifs = [Notification(
+        recipient_id=uid,
+        type='announcement',
+        title='系统公告',
+        content=content,
+        link_url='',
+        is_read=False,
+    ) for uid in user_ids]
+    Notification.objects.bulk_create(notifs, batch_size=500)
+    log_admin_action(request, 'announcement_publish', 'system',
+                     after={'recipients': len(notifs), 'content_preview': content[:80]})
+    return Response({'sent_to': len(notifs)})
+```
+
+URL 加路由:`path('admin/announcement/publish', views.admin_publish_announcement_view, ...)`。
+
+### 3. `apps/generation/views.py` `admin_settings_view` 改
+
+整体 `PUT /admin/settings` **保留** announcement / announcement_enabled 字段读写(让超管编辑器有数据来源),但**不再 fan-out**。fan-out 唯一入口是 `/admin/announcement/publish`。
+
+### 4. 老 endpoint 处理
+
+- `GET /api/v1/announcement` — 重写,返回当前用户**最新未读公告**(从 Notification 表),给老 AnnouncementModal 用
+- `POST /api/v1/announcement/read` — 重写,标记当前用户所有 type=announcement 未读为已读
+- 都保留 endpoint 兼容,内部走 Notification
+
+```python
+@api_view(['GET'])
+@permission_classes([IsAuthenticated])
+def announcement_view(request):
+    from apps.notifications.models import Notification
+    latest = Notification.objects.filter(
+        recipient=request.user, type='announcement', is_read=False
+    ).order_by('-created_at').first()
+    if not latest:
+        return Response({'announcement': '', 'enabled': False, 'is_read': True, 'notification_id': None})
+    return Response({
+        'announcement': latest.content,
+        'enabled': True,
+        'is_read': False,
+        'notification_id': latest.id,
+    })
+
+
+@api_view(['POST'])
+@permission_classes([IsAuthenticated])
+def announcement_read_view(request):
+    from apps.notifications.models import Notification
+    Notification.objects.filter(
+        recipient=request.user, type='announcement', is_read=False
+    ).update(is_read=True)
+    return Response({'success': True})
+```
+
+---
+
+## 三、前端改动
+
+### 1. `SettingsPage.tsx` 公告编辑区改
+
+现状:公告内容编辑器 + announcement_enabled checkbox + 跟其他设置一起"保存"。
+
+改成:
+- 删 announcement_enabled checkbox(不再有静默概念)
+- 公告编辑器下面加一个独立的【**发送公告**】按钮
+- 按钮点击 → confirm "确认发送给所有用户?发送后所有人打开页面会强制看到" → 确认 → `POST /admin/announcement/publish { content }` → 提示"已发送给 N 个用户"
+- 整体"保存"按钮**不再**改 announcement(避免误发)— 或者保留但只存草稿不触发 fan-out
+
+UX 说明:超管自己心里要清楚 — 编辑公告内容 = 写草稿,点【发送公告】= 真正发出。
+
+### 2. **全局** AnnouncementModal(强弹核心)
+
+现状:`AnnouncementModal` 只在 VideoGenerationPage L226-230 渲染,只在生成页弹。
+
+改成:**移到全局**(App.tsx ProtectedRoute 内部 或 顶层 layout),所有登录用户在任意页面都会触发。
+
+实现:
+- 在 App.tsx 顶层挂 `<GlobalAnnouncementGate />` 组件
+- 组件内 `useEffect`:登录后 / 路由变化时 / focus 回来时 → 调 `GET /announcement` → 有未读 → setShow(true)
+- 弹出 modal,用户必须点关闭 → `POST /announcement/read` → setShow(false)
+- 关闭后调 `useNotificationStore.getState().fetchUnreadCount()` 同步铃铛红点
+
+代码骨架:
+```tsx
+function GlobalAnnouncementGate() {
+  const user = useAuthStore((s) => s.user);
+  const [unread, setUnread] = useState<{ content: string; notification_id: number } | null>(null);
+  useEffect(() => {
+    if (!user) return;
+    const check = async () => {
+      try {
+        const { data } = await api.get('/announcement');
+        if (data.enabled && data.announcement && !data.is_read) {
+          setUnread({ content: data.announcement, notification_id: data.notification_id });
+        }
+      } catch {}
+    };
+    check();
+    const onVis = () => { if (!document.hidden) check(); };
+    document.addEventListener('visibilitychange', onVis);
+    return () => document.removeEventListener('visibilitychange', onVis);
+  }, [user]);
+  if (!unread) return null;
+  return (
+    <AnnouncementModal
+      forceOpen
+      content={unread.content}
+      onClose={async () => {
+        await api.post('/announcement/read');
+        setUnread(null);
+        useNotificationStore.getState().fetchUnreadCount();
+      }}
+    />
+  );
+}
+```
+
+`AnnouncementModal.tsx` 改成纯展示组件,数据从 prop 传入(`content`),不再自己 fetch。
+
+### 3. 删除 `VideoGenerationPage.tsx` 右上角小喇叭
+
+L150-165 整段 button 删掉,连带 `showAnnouncement` state 和那个 `<AnnouncementModal forceOpen ...>` 重看入口删掉(重看走消息中心)。
+
+### 4. `NotificationsPage.tsx` 每条加 type chip
+
+```tsx
+const TYPE_LABEL: Record<string, { text: string; color: string }> = {
+  announcement: { text: '公告', color: 'var(--color-info)' },
+  anomaly_disabled_user: { text: '安全', color: 'var(--color-danger)' },
+  anomaly_disabled_team: { text: '安全', color: 'var(--color-danger)' },
+  quota_warning: { text: '额度', color: 'var(--color-warning)' },
+  system: { text: '系统', color: 'var(--color-text-tertiary)' },
+};
+// 在 title 旁边渲染 <span style={{...chip风格}}>[{TYPE_LABEL[n.type].text}]</span>
+```
+
+announcement 类型的 content 用 DOMPurify + `dangerouslySetInnerHTML` 渲染(其他 type 用纯文本)。
+
+### 5. 删除废弃文件
+
+- `web/src/components/AnnouncementBanner.tsx`(已废弃,grep 确认无 import 后 rm)
+
+---
+
+## 四、边缘 case
+
+| case | 处理 |
+|------|------|
+| 公告发出后封禁某用户 | 该用户解封后能看到历史公告(因为 fan-out 时也发给了他) ✓ |
+| 新用户注册 | 看不到老公告(只 fan-out 给发布时存在的 user)— 可接受,公告时效性强 |
+| 超管点【发送公告】两次 | fan-out 两次,所有用户消息中心多两条记录 — 超管自己负责,UI 加二次 confirm 防误点 |
+| 公告内容为空点【发送】 | 400 报错"公告内容不能为空" |
+| 用户在路由 A 弹 modal 没关 → 切到 B | modal 跟随全局,在 B 继续显示。关闭前任何路由都被遮住 |
+| 同时多条未读公告 | 显示最新一条;关闭后下次 check 再显示下一条;一直到都读完 |
+| 老前端 PWA 缓存调 `/announcement` | endpoint 兼容,返回结构不变 |
+
+---
+
+## 五、测试
+
+新建 `web/test/announcement-integration-smoke.mjs`(~7 项):
+1. admin 登录 → 系统设置 → 写公告"测试 v1" → 点【发送公告】→ 二次 confirm → 提示"已发送给 N 个用户"
+2. 后端 Notification 表 fan-out ≥150 条 type=announcement
+3. tudou 登录 → 任意路由(/app)→ **自动弹 modal** 显示公告 HTML 内容
+4. 点关闭 → 标已读 → 再刷新 /app **不再弹**
+5. sidebar 铃铛红点同步 -1
+6. 进消息中心 → 看到这条公告 + 蓝色 [公告] chip + HTML 渲染
+7. admin 重新点【发送公告】(改了内容)→ tudou 再开页面又弹新公告
+
+回归:
+- tsc / vitest 71 162 / v0.20.1-smoke 11 / v2-smoke 25 / modal-interaction 8 都过
+
+---
+
+## 六、Commit 策略
+
+3 个 commit:
+1. `feat(notification): 公告整合进 Notification — fan-out + 强弹 Modal + chip + 删 announcement_enabled 概念`
+   - 后端:新 `/admin/announcement/publish` endpoint + TYPE_CHOICES + 重写 announcement_view/read_view
+   - 前端:GlobalAnnouncementGate 全局挂载 + AnnouncementModal 改纯展示 + SettingsPage 公告区加【发送】按钮删 checkbox + NotificationsPage chip + DOMPurify
+2. `refactor(notification): 删 VideoGenerationPage 公告小喇叭 + AnnouncementBanner 废弃文件`
+3. `test+docs: announcement-integration-smoke.mjs + 整合 plan 归档`
+
+---
+
+## 七、Critical Files
+
+修改:
+- `backend/apps/notifications/models.py` — TYPE_CHOICES 加 announcement
+- `backend/apps/generation/views.py` — 新增 `admin_publish_announcement_view` + 重写 `announcement_view` + `announcement_read_view`
+- `backend/apps/generation/urls.py` — 加路由
+- `web/src/App.tsx` — 挂 `<GlobalAnnouncementGate />`
+- `web/src/components/AnnouncementModal.tsx` — 改纯展示组件(props 接 content,不自己 fetch)
+- `web/src/components/VideoGenerationPage.tsx` — 删小喇叭 button + 删原 AnnouncementModal 调用
+- `web/src/pages/SettingsPage.tsx` — 删 announcement_enabled checkbox + 加【发送公告】按钮 + 二次 confirm
+- `web/src/pages/NotificationsPage.tsx` — 每条加 type chip + announcement HTML 渲染
+
+新建:
+- `web/src/components/GlobalAnnouncementGate.tsx`(或直接挂在 App.tsx 内部 function)
+- `web/test/announcement-integration-smoke.mjs`
+
+删除:
+- `web/src/components/AnnouncementBanner.tsx`
+
+不动:
+- `QuotaConfig.announcement` / `announcement_enabled` 字段(保留作为编辑数据源)
+- `User.last_read_announcement` 字段(免 migration,后续可清理)
+- `apps/notifications/` 主结构(已就绪)
+- Sidebar 大铃铛(已就绪,自然包含公告未读)
+
+---
+
+## 八、用户拍板顺序
+
+- 本 plan ✓(就是这版)
+- 写代码 + 测试 + 本地验证 ✅ 我自主做
+- 推 dev → **要授权**
+- 测试服跑通后合 master → **要授权**
