+# React 路由迁移矩阵
+
+状态值：`inventory`、`building`、`verification`、`complete`。
+
+| 路由 | 页面 | 角色/公开范围 | 关键合同 | 状态 |
+| --- | --- | --- | --- | --- |
+| `/login` | 登录 | 公开 | 验证码、密码、TOTP、SSO 设置、会话落盘 | building |
+| `/dashboard` | 教务总览 | 已登录用户 | `GET /api/dashboard`、角色视图、待办和学期 | building |
+| `/account` | 个人账户 | 已登录用户 | TOTP、Passkey、恢复码、SSO 绑定 | inventory |
+| `/users` | 用户与权限 | SuperAdmin | 列表、筛选、分页、创建、重置密码、角色范围 | inventory |
+
+后续从 `web/src/router/index.ts` 逐条补全。只有关键合同和各状态验收完整后，状态才能更新为 `complete`。
