+旧 `/project/{页面}` 和 `/market/project-management/{页面}` 地址跳转至 `/project/management/{页面}`。
 菜单种子不会给角色新增业务权限，应在现有角色管理分配项目管理权限及祖先菜单；

 ## ADDED Requirements
 
+### Requirement: 项目管理三级导航
+Web SHALL 使用“项目 → 项目管理 → 项目组管理 / 项目管理 / 业务统计 / 历史归属维护”层级，复用现有导航组件；原页面权限、名称和功能保持。
+#### Scenario: 现有角色升级
+- **WHEN** 执行项目管理分组迁移
+- **THEN** 保留子页面 ID 与原授权，仅为已授权子页面/编辑按钮的角色补齐目录祖先；全部项目选择权限仍独立挂在项目一级下，不授予管理页面权限。
+#### Scenario: 旧地址访问
+- **WHEN** 访问 `/project/{页面}` 或 `/market/project-management/{页面}`
+- **THEN** 携带原查询参数及 hash 跳转至 `/project/management/{页面}`，目标仍按原页面权限检查。
+
 ### Requirement: 组织信息与业务地点独立
 系统 SHALL 维护项目组负责人、成员及区域医院资料，区域医院仅为信息记录。
 #### Scenario: 修改负责医院

+## 2026-11-04 菜单增加项目管理分组
+
+用户明确指定层级：项目 → 项目管理 → 项目组管理 / 项目管理 / 业务统计 / 历史归属维护。仅重组现有菜单配置，复用市场三级导航，不新增业务页面或修改页面样式。沿用用户自测及先合入 V2.0 再测试的安排，工单保持开放。
+- [x] 同步 Web `sqxp.ts` 与后端 `menu.py`，新增 `menu:project:management` 目录，保留四个页面名称、组件和权限码。
+- [x] `staticRoutes.ts` 兼容两代旧地址，保留 query 与 hash。
+- [x] 新增 `2026-11-04-project_management_group.sql`，保留叶子 ID 与角色授权，仅补新祖先；全部项目权限仍独立挂在项目一级下，更新 README 顺序。
+- [x] 独立源码审查未发现 P1/P2，Git 差异核对通过；用户测试模式未运行测试或构建。
+- [ ] 提交续接 PR、合入 V2.0、同步主目录；备份并更新已确认测试库菜单，交付用户验收。
+
+以下为此前阶段历史记录；其中待合并等状态已由 2026-11-04 用户明确先合并再测试的指令取代。
+
 用户追加所属项目权限要求：将跨组选择从归属维护权限分离为 `project:project:all`（全部项目），默认仅项目组负责人/有效成员所在组内项目；Web与移动共用后端范围校验。
 - [x] 在 `backend/tests/test_project_selection_permissions.py` 增加成员/多组/无组、独立全部项目权限、多角色及职位继承、撤权、跨租户和越权提交用例，先执行确认失败。
 - [x] 在 `backend/app/services/project_management.py` 统一候选范围，赋值校验改用独立权限；筛选仍叠加原订单数据范围，历史回显与转换继承保持原有规则。
