+# Phase 2 PC 消息中心通知验收
+
+> 日期：2026-10-30
+> 范围：PC 消息中心增加「通知」Tab，与移动端消息中心对齐。
+
+## 1. 交付内容
+
+- `frontend/src/features/messages/MessagesPage.tsx`
+  - 新增「会话 / 通知」Tabs。
+  - 通知列表展示标题、正文、相对时间与未读点。
+  - 点击单条通知调用 `POST /notifications/:id/read` 并刷新列表。
+  - 顶栏支持「全部已读」，调用 `PUT /notifications/read-all`。
+  - 未读通知数量展示在 Tab 与页面顶部。
+- `frontend/src/styles/pc-messages.css`
+  - 新增 `.pc-messages-tabs`、`.pc-notice-list`、`.pc-notice-row*` 样式。
+  - 未读通知使用朱砂色圆点与浅色光晕，保持现有品牌语言。
+
+## 2. 验证记录
+
+| 检查 | 结果 |
+|---|---|
+| `npx tsc --noEmit` | 见提交时结果 |
+| `npm run build` | 见提交时结果 |
+| `GET /api/notifications` | 现有接口，移动端已在用 |
+
+## 3. 说明
+
+- 通知点击目前只标记已读，不自动跳转业务详情；后续可按 `biz_type/biz_id` 映射订单、申诉或公告。
+- 通知分页沿用 React Query `useInfiniteQuery`，每页 20 条。
