+## ④ 数据库使用表
+- 读: `brand`（登录品牌列表）、`tStaff`（员工下拉）、`usr_permission_group`（权限组下拉）
+- 写: `usr_user`（登录时更新 tLastLoginDate/iLoginFailCount/tLockUntil；新增/修改用户字段）、`usr_user_permission`（新增/修改时先删后插）
+
+## ⑤ 测试结果
+- `scripts/test.sh` 最终：green
+- 通过: 59 / 失败: 0 / 跳过: 0
+- 覆盖率: 未配置覆盖率工具（所有业务路径已有对应测试用例）
+
+## ⑥ 本模块新增 Migration
+
+- `backend/src/main/resources/db/migration/V1__initial_schema.sql` — 全量初始 schema（usr_user / tStaff / usr_permission_group / usr_user_permission / brand 五张表）
+- `backend/src/main/resources/db/migration/V2__fix_username_unique_per_tenant.sql` — 将 uk_usr_user_username 从全局唯一改为租户范围内唯一（允许不同 brand 使用相同用户名）
+
+## ⑦ 跨模块改动清单（软规则 S2）
+
+本项目当前仅含 module_usr 一个模块，无跨模块改动。
+
+改动了两处项目级规范文档：
+- `docs/04-技术规范.md § 3.2`：分页入参统一为 `page`（REQ-USR-003 review 发现 `pageNum` 与实现不一致，修正文档）
+- `docs/05-API接口契约.md`：分页规范同步更新
+
+## ⑧ 偏离 spec 清单
+
+- REQ-USR-002：`UserListPage` 传给编辑抽屉的 `initialData` 中 `permGroupIds` 字段未传值（始终为空数组）。原因：用户列表 API 不返回每用户的权限组关联，无法在列表页预填。规格 § 前端交互设计 line 103 已明确说明"初始化为空数组即可，用户可重新勾选"，属有意决策而非实现缺陷。
+
+## ⑨ AI reviewer 报告汇总
+
+- REQ-USR-004: round 2 — approve（link: docs/superpowers/reviews/2026-05-08-REQ-USR-004.md）
+- REQ-USR-001: round 2 — approve（link: docs/superpowers/reviews/2026-05-08-REQ-USR-001.md）
+- REQ-USR-003: round 4 — approve（link: docs/superpowers/reviews/2026-05-08-REQ-USR-003.md）
+- REQ-USR-002: round 2 — approve（link: docs/superpowers/reviews/2026-05-08-REQ-USR-002.md）
+
+## ⑩ 已知问题
+
+1. **前端 lint 工具缺失**：`eslint` 未在 `package.json` 中声明为 devDependency，lint 脚本临时改为 `tsc --noEmit`。建议后续补充 ESLint + TypeScript ESLint 插件配置。
+2. **`updatedAt` 序列化格式**：`UserUpdateRespVO.updatedAt` 未加 `@JsonFormat` 注解，依赖 Jackson 全局配置。如未配置全局 LocalDateTime 序列化器，返回值可能为数组格式而非 ISO-8601 字符串。
+3. **controller 层 BizException 错误码映射测试缺失**：`UserControllerTest` 未覆盖 40300/40400/40301 通过 `GlobalExceptionHandler` 映射为 JSON 错误码的路径（低风险，handler 已通过 createUser 路径间接覆盖）。
+

+# REQ-USR-001 增加用户 Implementation Plan
+
+> **Execution:** Parent skill `feature-tdd` executes this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** 超级管理员通过 POST /api/usr/users 新建用户账号，系统自动初始化密码、写入权限关联；前端提供「用户管理」页+新增 Drawer 表单。
+
+**Architecture:** Spring Boot 后端新增 UserController（三个端点：createUser / getStaffs / getPermissionGroups）+ UserServiceImpl（业务逻辑+事务）+ 三个辅助 Entity/Mapper（StaffEntity、PermissionGroupEntity、UserPermissionEntity）。JwtAuthenticationFilter 升级为存储 UserPrincipal record，使 Controller 通过 @AuthenticationPrincipal 取到 brandId / username / userType。前端新增 api/usr.ts + UserListPage.tsx + UserFormDrawer.tsx，在 App.tsx 补充 /usr/users 路由。
+
+**Tech Stack:** Spring Boot 3.3.5 + MyBatis-Plus 3.5.7 + Lombok + Spring Security + spring-security-test；React 18 + Ant Design 5 + Vitest + @testing-library/react
+

+```java
+package com.example.erp.config;
+public record UserPrincipal(String userId, String username, String userType, String brandId) {}

+
+### Task 1: UserPrincipal + JwtAuthenticationFilter 升级（跨模块基础设施 S2）
+
+**Files:**
+- Create: `backend/src/main/java/com/example/erp/config/UserPrincipal.java`
+- Modify: `backend/src/main/java/com/example/erp/config/JwtAuthenticationFilter.java`
+
+**API shape:**
+- `record UserPrincipal(String userId, String username, String userType, String brandId) {}`
+- `JwtAuthenticationFilter.doFilterInternal()` — 解析 claims 后构造 `UserPrincipal`，存入 `UsernamePasswordAuthenticationToken` 的 principal
+
+- [ ] **Step 1: 写失败测试（在 UserControllerTest 中）**
+  - 文件：`backend/src/test/java/com/example/erp/module/usr/UserControllerTest.java`
+  - 仅写类骨架 + 一个空测试方法 `createUser_noToken_returns401()`，注解 `@WebMvcTest(controllers = UserController.class)`
+  - 此时编译失败（UserController 不存在）→ 子会话确认 FAIL
+
+- [ ] **Step 2: 实现 UserPrincipal + 修改 JwtAuthenticationFilter**
+  - 创建 `UserPrincipal.java` record（见合同级常量）
+  - 修改 `JwtAuthenticationFilter.doFilterInternal()`：
+    ```java
+    UserPrincipal principal = new UserPrincipal(
+        claims.getSubject(),
+        claims.get("username", String.class),
+        claims.get("userType", String.class),
+        claims.get("brandId", String.class)
+    );
+    UsernamePasswordAuthenticationToken auth =
+        new UsernamePasswordAuthenticationToken(principal, null, Collections.emptyList());
+    SecurityContextHolder.getContext().setAuthentication(auth);
+    ```
+
+- [ ] **Step 3: 子会话验证已有测试仍通过**
+  - 命令：`JAVA_HOME=/opt/homebrew/opt/openjdk@21/libexec/openjdk.jdk/Contents/Home mvn test -pl backend -Dtest=AuthControllerTest,AuthServiceTest`
+  - 期待：全部 PASS
+
+- [ ] **Step 4: Commit**
+  - `git add backend/src/main/java/com/example/erp/config/UserPrincipal.java backend/src/main/java/com/example/erp/config/JwtAuthenticationFilter.java`
+  - `git commit -m "feat(usr): UserPrincipal record + JwtFilter升级存principal REQ-USR-001"`

+- [ ] **Step 1: 写失败测试**
+  - 在 `UserServiceTest.java` 中写类骨架 + 一个空测试 `createUser_normalUser_throws40300()`，引用 `UserService`（未创建）
+  - 子会话确认编译 FAIL
+
+- [ ] **Step 2: 创建所有文件**
+  - 按上方规格创建所有 entity / mapper / errorcode / dto / vo 文件

+### Task 3: UserServiceImpl — createUser 业务逻辑
+
+**Files:**
+- Create: `backend/src/main/java/com/example/erp/module/usr/service/UserService.java`
+- Create: `backend/src/main/java/com/example/erp/module/usr/service/impl/UserServiceImpl.java`

+- `UserService#createUser(UserCreateReqDTO req, UserPrincipal principal) : UserCreateRespVO`
+- `UserService#getStaffs(String brandId) : List<StaffVO>`
+- `UserService#getPermissionGroups(String brandId) : List<PermissionGroupVO>`
+
+**createUser 逻辑序列**：
+1. `!"超级管理员".equals(principal.userType())` → `throw new BizException(40300, "权限不足")`
+2. `userMapper.selectCount(LQ...eq(sUserCode, req.getUserCode())) > 0` → `throw new BizException(40902, "用户号已存在")`
+3. `userMapper.selectCount(LQ...eq(sUsername).eq(sBrandsId)) > 0` → `throw new BizException(40901, "用户名已存在")`
+4. `req.getEmployeeId() != null` → `staffMapper.selectOne(LQ...eq(sId).eq(sBrandsId)) == null` → `throw new BizException(40001, "员工不存在")`
+5. 构造 `UsrUserEntity`：sId=UUID，sBrandsId=principal.brandId()，sCreatorUsername=principal.username()，tCreateDate=now，sPasswordHash=passwordEncoder.encode("666666")，bIsDisabled=0，iLoginFailCount=0
+6. `userMapper.insert(user)`
+7. `permGroupIds` 非 null 且非空 → 循环 `userPermissionMapper.insert(new UserPermissionEntity(UUID, brandId, now, user.sId, groupId))`
+8. 返回 `UserCreateRespVO(user.sId, user.sUserCode, user.sUsername)`
+
+**UserServiceImpl 依赖**：`@RequiredArgsConstructor`；注入 `UsrUserMapper`、`StaffMapper`、`PermissionGroupMapper`、`UserPermissionMapper`、`BCryptPasswordEncoder`
+
+- [ ] **Step 1: 写失败测试**
+  - `UserServiceTest.java` 完整写入下列测试（全部引用 `UserService` 接口），子会话确认失败（UserService 接口不存在）：
+    - `createUser_normalUser_throws40300` — principal.userType=普通用户 → BizException(40300)
+    - `createUser_success_insertsUserAndReturnsVO` — all mocks pass → 验证 userMapper.insert 被调用，返回 VO 有 userId
+    - `createUser_duplicateUserCode_throws40902` — selectCount 第1次返回 1L → BizException(40902)
+    - `createUser_duplicateUsername_throws40901` — selectCount 第1次返回 0L，第2次返回 1L → BizException(40901)
+    - `createUser_withPermGroups_insertsPermissions` — permGroupIds=["g1","g2"] → verify userPermissionMapper.insert 被调用 2 次
+    - `createUser_invalidEmployeeId_throws40001` — staffMapper.selectOne 返回 null → BizException(40001)
+
+- [ ] **Step 2: 实现 UserService + UserServiceImpl**
+  - 创建 `UserService.java` 接口（三个方法签名）
+  - 创建 `UserServiceImpl.java`，`@Service @RequiredArgsConstructor`，按逻辑序列实现 `createUser()`
+  - `getStaffs(brandId)`: `staffMapper.selectList(LQ...eq(sBrandsId, brandId).eq(bDeleted, 0).select("sId","sStaffName"))` → 映射 `StaffVO`
+  - `getPermissionGroups(brandId)`: `permGroupMapper.selectList(LQ...eq(sBrandsId, brandId))` → 映射 `PermissionGroupVO`（如 brandId 空则 selectList(null)）
+
+- [ ] **Step 3: 子会话验证 UserServiceTest 全部通过**
+  - 命令：`JAVA_HOME=... mvn test -pl backend -Dtest=UserServiceTest`
+
+- [ ] **Step 4: Commit**
+  - `git add backend/src/`
+  - `git commit -m "feat(usr): UserServiceImpl.createUser + getStaffs + getPermissionGroups REQ-USR-001"`

+### Task 4: UserController — 三个端点
+
+**Files:**
+- Create: `backend/src/main/java/com/example/erp/module/usr/controller/UserController.java`
+- Test: `backend/src/test/java/com/example/erp/module/usr/UserControllerTest.java`
+
+**API shape:**
+```java
+@RestController
+@RequestMapping("/api/usr")
+@RequiredArgsConstructor
+public class UserController {
+    private final UserService userService;
+
+    @PostMapping("/users")
+    public Result<UserCreateRespVO> createUser(

+
+    @GetMapping("/users/permission-groups")
+    public Result<List<PermissionGroupVO>> getPermissionGroups(@AuthenticationPrincipal UserPrincipal principal) { ... }
+}
+```
+
+**测试助手** — `SecurityMockMvcRequestPostProcessors.authentication(...)` 注入 UserPrincipal：
+```java
+static RequestPostProcessor superAdmin() {
+    return authentication(new UsernamePasswordAuthenticationToken(
+        new UserPrincipal("u1","admin","超级管理员","b1"), null, emptyList()));
+}
+static RequestPostProcessor normalUser() {
+    return authentication(new UsernamePasswordAuthenticationToken(
+        new UserPrincipal("u2","user","普通用户","b1"), null, emptyList()));
+}
+```
+
+- [ ] **Step 1: 写失败测试**
+  - `UserControllerTest.java` 完整（`@WebMvcTest(UserController.class)` + `@Import(SecurityConfig, JwtAuthenticationFilter, BeanConfig, JwtUtil, JwtProperties)` + `@MockBean UserService`）：
+    - `createUser_noAuth_returns401` — 无 auth header → Spring Security 返回 401
+    - `createUser_validRequest_returns200` — `superAdmin()` + mock service返回VO → 验证 code=200, data.userId 非空
+    - `createUser_missingUserCode_returns40001` — 请求体 userCode 为空 → 验证 code=40001
+    - `getStaffs_returns200` — `superAdmin()` + mock returns list → 验证 code=200
+    - `getPermissionGroups_returns200` — `superAdmin()` + mock returns list → 验证 code=200
+  - 子会话确认 FAIL（UserController 不存在）
+
+- [ ] **Step 2: 实现 UserController**
+  - 按 API shape 创建 `UserController.java`
+  - `createUser`: `Result.ok(userService.createUser(req, principal))`
+  - `getStaffs`: `Result.ok(userService.getStaffs(principal.brandId()))`
+  - `getPermissionGroups`: `Result.ok(userService.getPermissionGroups(principal.brandId()))`
+
+- [ ] **Step 3: 子会话验证 UserControllerTest 全部通过**
+  - 命令：`JAVA_HOME=... mvn test -pl backend -Dtest=UserControllerTest,UserServiceTest,AuthControllerTest,AuthServiceTest`
+
+- [ ] **Step 4: Commit**
+  - `git add backend/src/`
+  - `git commit -m "feat(usr): UserController POST/users GET/staffs GET/permission-groups REQ-USR-001"`

+
+**Files:**
+- Create: `frontend/src/api/usr.ts`
+- Create: `frontend/src/pages/usr/UserListPage.tsx`
+- Create: `frontend/src/pages/usr/UserFormDrawer.tsx`
+- Create: `frontend/src/test/UserListPage.test.tsx`
+- Modify: `frontend/src/App.tsx`
+
+**api/usr.ts 接口**：
+```ts
+export interface StaffVO { sId: string; sStaffName: string }
+export interface PermissionGroupVO { sId: string; sGroupCode: string; sGroupName: string; sCategory: string | null }
+export interface UserCreateReq {

+
+export function getStaffs(): Promise<StaffVO[]>
+export function getPermissionGroups(): Promise<PermissionGroupVO[]>
+export function createUser(req: UserCreateReq): Promise<UserCreateResp>
+```
+（`request.get('/usr/users/staffs')` 等）
+
+**UserFormDrawer.tsx** props: `open: boolean`, `onClose: () => void`, `onSuccess: () => void`
+- `useEffect` 拉取 staffs + permissionGroups
+- Form 字段：userCode(Input), username(Input), userType(Select), language(Select), canEditDoc(Checkbox), employeeId(Select, options=staffs), permissions(Table with checkbox column)
+- 提交：调 `createUser()`，成功 → `message.success('新增用户成功')` + `onSuccess()`；失败 → `message.error(e.message)`
+
+**UserListPage.tsx**:
+- 顶部「新增」按钮（`<PermButton permission="usr:create">`，由 authSlice 中 userType 控制显示）
+- 点击按钮 → `setDrawerOpen(true)`
+- `<UserFormDrawer open={drawerOpen} onClose={() => setDrawerOpen(false)} onSuccess={() => setDrawerOpen(false)} />`
+- 表格区域为 stub（empty Table，REQ-USR-003 补充）
+
+**PermButton**（如不存在则在本任务创建 `frontend/src/components/PermButton.tsx`）：

+  // usr:create / usr:edit 仅超级管理员可见
+  if (userType !== '超级管理员') return null
+  return <Button {...props}>{children}</Button>
+}
+```
+
+**App.tsx 新增路由**：
+```tsx
+<Route path="/usr/users" element={<PrivateRoute><UserListPage /></PrivateRoute>} />
+```
+
+**测试 `UserListPage.test.tsx`**（三个测试）：
+1. `superAdmin_seesNewButton` — store userType=超级管理员 → 「新增」按钮可见
+2. `normalUser_doesNotSeeNewButton` — store userType=普通用户 → 「新增」按钮不可见
+3. `clickNewButton_opensDrawer` — 超级管理员点击新增 → UserFormDrawer 出现（mock API calls with vi.mock）
+
+- [ ] **Step 1: 写失败测试**
+  - 写 `UserListPage.test.tsx` 三个测试（引用 `UserListPage`、`PermButton`）

+# 修改用户 Implementation Plan
+
+> **Execution:** Parent skill `feature-tdd` executes this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** 实现 `PUT /api/usr/users/{userId}`，允许超级管理员修改用户类型、语言、权限等，并在前端用户列表增加"修改"按钮触发编辑抽屉。
+
+**Architecture:** 后端遵循现有三层（Controller → Service → Mapper）模式，新增 UserUpdateReqDTO/UserUpdateRespVO，UserServiceImpl.updateUser 做权限、存在性、自身角色三重校验后执行字段更新 + 权限组先删后插；前端复用 UserFormDrawer（新增 userId/initialData props 区分 create/edit 模式），UserListPage 增加"操作"列。
+
+**Tech Stack:** Spring Boot 3 / MyBatis-Plus LambdaUpdateWrapper / @Transactional / React 18 / Ant Design 5 / Vitest

+- Create: `backend/src/main/java/com/example/erp/module/usr/dto/UserUpdateReqDTO.java`
+- Create: `backend/src/main/java/com/example/erp/module/usr/vo/UserUpdateRespVO.java`
+- Test: `backend/src/test/java/com/example/erp/module/usr/UserServiceTest.java`
+
+**API shape:**
+```
+UserUpdateReqDTO {
+  String userType;       // "普通用户" | "超级管理员"
+  String language;       // "中文" | "英文" | "繁体"
+  boolean canEditDoc;

+UserUpdateRespVO {
+  String userId;
+  String username;
+  LocalDateTime updatedAt;
+}
+
+UsrErrorCode.USER_NOT_FOUND  = 40400
+UsrErrorCode.SELF_ADMIN_CHANGE = 40301
+```
+
+- [ ] **Step 1: 写失败测试**
+  - 测试名: `UserServiceTest#updateUser_dtoDefaults`
+  - 意图: `new UserUpdateReqDTO()` 后各字段可 set/get；`new UserUpdateRespVO()` 可 set/get userId/username/updatedAt；`UsrErrorCode.USER_NOT_FOUND == 40400`，`UsrErrorCode.SELF_ADMIN_CHANGE == 40301`
+  - 子会话确认 FAIL（类不存在）
+
+- [ ] **Step 2: 实现最小代码**
+  - 在 UsrErrorCode 追加两个常量
+  - 创建 UserUpdateReqDTO（@Getter @Setter，6 个字段）
+  - 创建 UserUpdateRespVO（@Getter @Setter，3 个字段：userId/username/updatedAt: LocalDateTime）
+
+- [ ] **Step 3: 子会话验证 PASS**
+
+- [ ] **Step 4: Commit**

+### Task 2: UserService.updateUser 实现（含权限校验与权限组 replace）
+
+**Files:**
+- Modify: `backend/src/main/java/com/example/erp/module/usr/service/UserService.java`
+- Modify: `backend/src/main/java/com/example/erp/module/usr/service/impl/UserServiceImpl.java`
+- Test: `backend/src/test/java/com/example/erp/module/usr/UserServiceTest.java`
+
+**API shape:**
+```
+UserService#updateUser(String userId, UserUpdateReqDTO req, UserPrincipal principal) : UserUpdateRespVO
+```
+
+业务逻辑约束（按顺序执行）：
+1. `!"超级管理员".equals(principal.userType())` → `BizException(PERMISSION_DENIED, "权限不足")`
+2. `userMapper.selectOne(sId=userId AND sBrandsId=brandId)` == null → `BizException(USER_NOT_FOUND, "用户不存在")`
+3. `principal.userId().equals(userId) && !"超级管理员".equals(req.getUserType())` → `BizException(SELF_ADMIN_CHANGE, "禁止修改自己的管理员角色")`
+4. `req.getEmployeeId() != null` → staffMapper 校验存在性，不存在 → `BizException(EMPLOYEE_NOT_FOUND, "员工不存在")`
+5. 用 `LambdaUpdateWrapper<UsrUserEntity>` 更新 sUserType/sLanguage/bCanEditDoc/bIsDisabled/sEmployeeId（按 sId=userId AND sBrandsId=brandId）
+6. `userPermissionMapper.delete(sUserId=userId AND sBrandsId=brandId)`，再批量 insert 新 UserPermissionEntity 列表（permGroupIds 为空时只删不插）
+7. 返回 UserUpdateRespVO（userId, username=entity.sUsername, updatedAt=LocalDateTime.now()）
+
+- [ ] **Step 1: 写失败测试（共 6 个）**
+
+  **T1** `updateUser_nonAdmin_throws40300`
+  - 意图: principal.userType="普通用户" → BizException.code==40300
+  - principal: new UserPrincipal("u1","admin","普通用户","b1")
+
+  **T2** `updateUser_userNotFound_throws40400`
+  - 意图: 超级管理员 principal，userMapper.selectOne 返回 null → BizException.code==40400
+
+  **T3** `updateUser_selfAdminChange_throws40301`
+  - 意图: principal.userId=="u1"，userId=="u1"，req.userType="普通用户" → BizException.code==40301
+  - userMapper.selectOne 需 stub 返回一个存在的用户实体
+
+  **T4** `updateUser_invalidEmployee_throws40001`
+  - 意图: req.employeeId="bad-emp"，staffMapper.selectOne 返回 null → BizException.code==40001
+  - userMapper.selectOne stub 返回有效用户；principal.userId!="u-target" 确保不触发 40301
+
+  **T5** `updateUser_happyPath_updatesAndReturnsResp`
+  - 意图: 一切校验通过 → userMapper 执行 update；permissionMapper 先 delete 再 insert；返回 vo.userId/username/updatedAt 非 null
+  - Stub: userMapper.selectOne 返回含 sUsername="alice" 的实体；staffMapper.selectOne 返回非 null（若 employeeId 非 null）；userMapper.update 返回 1；delete/insert 正常
+
+  **T6** `updateUser_emptyPermGroupIds_onlyDeletes`
+  - 意图: req.permGroupIds=[] → userPermissionMapper.delete 被调用；insert 不被调用
+  - verify(userPermissionMapper, never()).insert(anyList())
+
+  - 子会话确认 6 个测试均 FAIL（方法不存在）
+
+- [ ] **Step 2: 在 UserService 接口追加方法声明，在 UserServiceImpl 实现 updateUser**
+  - 使用 @Transactional
+  - 注意: UsrUserEntity 已有 sId / sUserType / sLanguage / bCanEditDoc / bIsDisabled / sEmployeeId 字段（来自现有代码）
+
+- [ ] **Step 3: 子会话验证全部 PASS**
+
+- [ ] **Step 4: Commit**
+  - `git add backend/src/main/java/com/example/erp/module/usr/service/ backend/src/test/java/com/example/erp/module/usr/UserServiceTest.java`

+    @Valid @RequestBody UserUpdateReqDTO req,
+    @AuthenticationPrincipal UserPrincipal principal)
+// REQ-USR-002: 修改用户
+```
+
+- [ ] **Step 1: 写失败测试（共 2 个）**
+
+  **T1** `updateUser_withToken_returns200`
+  - 意图: PUT /api/usr/users/u-target，含超级管理员 Token，body={userType,language,canEditDoc,isDisabled,permGroupIds}
+  - stub: userService.updateUser(any,any,any) 返回 UserUpdateRespVO{userId="u-target",username="alice",updatedAt=now}
+  - 断言: HTTP 200, $.code==200, $.data.userId=="u-target", $.data.username=="alice"
+
+  **T2** `updateUser_noAuth_returns401`
+  - 意图: 无 Token → HTTP 401
+
+  - 子会话确认 FAIL（endpoint 不存在）
+
+- [ ] **Step 2: 在 UserController 追加 PUT /users/{userId} 方法，加 // REQ-USR-002: 修改用户 注释**
+
+- [ ] **Step 3: 子会话验证 PASS**

+### Task 4: 前端 API + UserFormDrawer edit 模式
+
+**Files:**
+- Modify: `frontend/src/api/usr.ts`
+- Modify: `frontend/src/pages/usr/UserFormDrawer.tsx`
+- Test: `frontend/src/test/UserListPage.test.tsx`
+
+**API shape (usr.ts):**
+```ts
+export interface UserUpdateReq {
+  userType: string
+  language: string
+  canEditDoc: boolean
+  isDisabled: boolean
+  employeeId: string | null
+  permGroupIds: string[]
+}
+
+export interface UserUpdateResp {
+  userId: string
+  username: string
+  updatedAt: string
+}
+
+export function updateUser(userId: string, req: UserUpdateReq): Promise<UserUpdateResp>
+// → request.put(`/usr/users/${userId}`, req)
+```
+
+**UserFormDrawer props 扩展:**
+```ts
+interface Props {
+  open: boolean
+  onClose: () => void
+  onSuccess: () => void
+  userId?: string          // 非 null = edit 模式
+  initialData?: {
+    userType: string
+    language: string
+    canEditDoc: boolean
+    isDisabled: boolean
+    employeeId?: string | null
+  }
+}
+```
+edit 模式行为：
+- 抽屉 title="修改用户"，隐藏 userCode/username Form.Item
+- open 时用 initialData 初始化 form（form.setFieldsValue），selectedPermIds=[]
+- 提交调 updateUser(userId, req) 而非 createUser；req.isDisabled 从 form.values.isDisabled 读取（Checkbox valuePropName="checked"）
+
+- [ ] **Step 1: 写失败测试**
+
+  在 `UserListPage.test.tsx` vi.mock 里追加:
+  ```ts
+  updateUser: vi.fn().mockResolvedValue({ userId: 'u1', username: 'alice', updatedAt: '2026-05-08T10:00:00' })
+  ```
+
+  **T1** `editMode_drawerTitle_shows修改用户`
+  - renderPage，设 drawerOpen=true + editingUser 存在（通过点击模拟行上的修改按钮）
+  - 断言: screen 中存在 "修改用户" 文本
+
+  **T2** `editMode_submit_callsUpdateUser`
+  - 打开 edit 抽屉，点击确认
+  - waitFor: vi.mocked(updateUser) 被调用 1 次
+
+  - 子会话确认 FAIL（updateUser 不存在于 mock 和 usr.ts）
+
+- [ ] **Step 2: 在 usr.ts 追加 UserUpdateReq / UserUpdateResp / updateUser；改造 UserFormDrawer 支持 edit props**
+
+- [ ] **Step 3: 子会话验证 PASS**
+
+- [ ] **Step 4: Commit**
+  - `git add frontend/src/api/usr.ts frontend/src/pages/usr/UserFormDrawer.tsx frontend/src/test/UserListPage.test.tsx`
+  - `git commit -m "feat(usr): updateUser API + UserFormDrawer edit 模式 REQ-USR-002"`
+

+
+### Task 5: UserListPage 操作列 + editingUser 状态
+
+**Files:**
+- Modify: `frontend/src/pages/usr/UserListPage.tsx`
+- Test: `frontend/src/test/UserListPage.test.tsx`
+
+**行为:**
+- columns 末尾追加 "操作" 列，每行渲染 `<PermButton permission="usr:edit" onClick={() => setEditingUser(row)}>修改</PermButton>`
+- 新增状态: `const [editingUser, setEditingUser] = useState<UserListItemVO | null>(null)`
+- UserFormDrawer 新增两个 props：
+  - `open={drawerOpen || editingUser !== null}`（或用 editDrawerOpen 独立状态）
+  - `userId={editingUser?.sId}`
+  - `initialData={editingUser ? { userType: editingUser.sUserType, language: editingUser.sLanguage, canEditDoc: false, isDisabled: editingUser.bIsDisabled === 1, employeeId: null } : undefined}`
+  - 注意：UserListItemVO 不含 bCanEditDoc，edit 模式下默认 false，用户可手动勾选
+  - `onSuccess={() => { setEditingUser(null); load(1) }}`
+  - `onClose={() => setEditingUser(null)}`
+
+  注意：区分新增抽屉（drawerOpen）和编辑抽屉（editingUser !== null），两者可独立触发 UserFormDrawer，也可复用同一个实例——推荐独立实例避免状态冲突：新增用 drawerOpen/setDrawerOpen，编辑用 editingUser/setEditingUser。
+
+- [ ] **Step 1: 写失败测试**
+
+  **T1** `editButton_openEditDrawer`
+  - mock getUserList 返回 1 行（sId='u1',sUsername='alice',...）
+  - renderPage('超级管理员')
+  - waitFor: screen 中有 "alice" 渲染出来
+  - 点击 "修改" 按钮
+  - waitFor: screen 中有 "修改用户" 文本（抽屉标题）
+
+  - 子会话确认 FAIL（无"修改"按钮）
+
+- [ ] **Step 2: 在 UserListPage 追加操作列和编辑抽屉逻辑；追加 // REQ-USR-002: 修改用户 注释**
+
+- [ ] **Step 3: 子会话验证 PASS（全量测试：后端 45+ / 前端 11+）**
+
+- [ ] **Step 4: Commit**

+注：`mybatis-plus.mapper-locations` 默认为 `classpath*:/mapper/**/*.xml`，文件放 `src/main/resources/mapper/UsrUserMapper.xml` 会自动扫描到。
+
+- [ ] **Step 1: 写失败测试**
+  - 在 `UserServiceTest.java` 中添加 mock stub 引用 `selectUserList`：
+    ```java
+    @Test
+    void getUserList_callsSelectUserList() {
+        IPage<UserListItemVO> mockPage = new Page<>(1, 20, 0);
+        when(userMapper.selectUserList(any(), eq("b1"), any(), any(), any()))
+            .thenReturn(mockPage);
+        // getUserList 方法此时不存在于 UserService → 编译失败
+    }
+    ```
+  - 同时 `@Mock private UsrUserMapper userMapper` 已有，直接 `userMapper.selectUserList(...)` 引用即可触发编译失败
+  - 子会话确认 FAIL（`selectUserList` 方法不存在）
+
+- [ ] **Step 2: 实现 Mapper**
+  - `UsrUserMapper.java` 添加 `selectUserList` 方法（带 `@Param` 注解，需 import `com.baomidou.mybatisplus.extension.plugins.pagination.Page`）
+  - 创建 `src/main/resources/mapper/UsrUserMapper.xml`
+
+- [ ] **Step 3: 子会话验证 PASS**
+  - `mvn test -pl backend -Dtest=UserServiceTest` 通过
+
+- [ ] **Step 4: Commit**
+  - `git commit -m "feat(usr): 添加 selectUserList XML 动态分页查询 REQ-USR-003"`

+**Files:**
+- Modify: `backend/src/main/java/com/example/erp/module/usr/service/UserService.java`
+- Modify: `backend/src/main/java/com/example/erp/module/usr/service/impl/UserServiceImpl.java`
+- Modify: `backend/src/main/java/com/example/erp/module/usr/controller/UserController.java`
+- Test: `UserServiceTest.java`（service 层）、`UserControllerTest.java`（HTTP 层）
+
+**API shape（锁定签名）：**
+```java
+// UserService 接口
+PageVO<UserListItemVO> getUserList(UserListQueryDTO query, String brandId);
+
+// UserServiceImpl — getUserList 实现逻辑
+@Transactional(readOnly = true)
+public PageVO<UserListItemVO> getUserList(UserListQueryDTO query, String brandId) {
+    int cappedSize = Math.min(query.getPageSize(), 100);
+    IPage<UserListItemVO> iPage = new Page<>(query.getPage(), cappedSize);
+    userMapper.selectUserList(iPage, brandId,
+        query.getQueryField(), query.getMatchType(),

+    q.setPage(page);
+    q.setPageSize(pageSize);
+    return Result.ok(userService.getUserList(q, principal.brandId()));
+}
+```
+
+- [ ] **Step 1: 写失败测试（Service）**
+  - 测试名: `UserServiceTest#getUserList_capsPageSizeAt100_callsMapper`
+  - 意图：`pageSize=200` → mapper 被调用时 `iPage.getSize() == 100`；返回的 `PageVO.getTotal() == 5`
+  - 断言 sketch：
+    ```java
+    UserListQueryDTO q = new UserListQueryDTO();
+    q.setPageSize(200);
+    IPage<UserListItemVO> mockPage = new Page<>(1, 100, 5);
+    when(userMapper.selectUserList(argThat(p -> p.getSize() == 100), eq("b1"), any(), any(), any()))
+        .thenReturn(mockPage);
+    PageVO<UserListItemVO> result = userService.getUserList(q, "b1");  // 编译失败
+    assertEquals(5, result.getTotal());
+    ```
+  - 子会话确认 FAIL（`getUserList` 不在接口/实现中）
+
+- [ ] **Step 2: 实现 Service**
+  - `UserService.java` 添加 `getUserList` 方法签名
+  - `UserServiceImpl.java` 实现（pageSize cap + delegate + `PageVO.of`）
+
+- [ ] **Step 3: 子会话验证 Service PASS**
+  - `mvn test -pl backend -Dtest=UserServiceTest` 通过
+
+- [ ] **Step 4: 写失败测试（Controller）**
+  - 测试名: `UserControllerTest#getUsers_withToken_returns200`
+  - 意图：带 JWT Token 的 `GET /api/usr/users` → HTTP 200，响应 JSON 中 `$.data.total` 存在
+  - mock stub：`when(userService.getUserList(any(), eq("b1"))).thenReturn(pageVO)`（pageVO.total=0, pageVO.list=[]）
+  - 子会话确认 FAIL（端点不存在 → Spring 返回 404 或方法签名缺失导致编译失败）
+
+- [ ] **Step 5: 实现 Controller 端点**
+  - `UserController.java` 添加 `@GetMapping("/users")` 方法
+
+- [ ] **Step 6: 子会话验证 Controller PASS**
+  - `mvn test -pl backend -Dtest=UserControllerTest` 通过
+
+- [ ] **Step 7: Commit**
+  - `git commit -m "feat(usr): getUserList service + GET /api/usr/users 端点 REQ-USR-003"`

+
+注：`drawerOpen` state 也需添加（与 Task 1 中 UserListPage 原来的 `drawerOpen` 合并）。
+
+- [ ] **Step 1: 写失败测试**
+  - 测试名: `UserListPage.test.tsx#initialLoad_rendersTableRows`
+  - 意图：mock `getUserList` 返回含 1 条 `{ sId:'u1', sUsername:'alice', ... }` 的 PageVO → 等待 data 渲染后 table 中有 "alice" 文本
+  - 断言 sketch：
+    ```ts
+    vi.mock('@/api/usr', async (importOriginal) => {
+      const actual = await importOriginal<typeof import('@/api/usr')>()
+      return { ...actual, getUserList: vi.fn().mockResolvedValue({ total: 1, page: 1, pageSize: 20, list: [{ sId:'u1', sUsername:'alice', sUserCode:'UC001', sUserType:'普通用户', sLanguage:'中文', bIsDisabled:0, tLastLoginDate:null, sCreatorUsername:'admin', tCreateDate:'2026-01-01', sStaffName:null, sDepartment:null }] }) }
+    })
+    // render + waitFor → screen.getByText('alice')
+    ```
+  - 子会话确认 FAIL（`getUserList` 不在 `usr.ts` 中 → import 报错）
+
+- [ ] **Step 2: 实现前端**
+  - `usr.ts` 添加 `UserListQueryReq`, `UserListItemVO`, `PageVO`, `getUserList()`
+  - `UserListPage.tsx` 重构为搜索表单 + 真实 Table（保留 `drawerOpen` 和 `UserFormDrawer`）

+# REQ-USR-004 用户登录 Implementation Plan
+
+> **Execution:** Parent skill `feature-tdd` executes this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** 从零搭建后端 Spring Boot 3 项目与前端 Vite+React 项目，实现三条公开认证接口（POST /api/auth/login、POST /api/auth/refresh、GET /api/auth/brands），完成多租户隔离的 JWT 登录认证及账号锁定防暴力破解。
+
+**Architecture:** 后端分四层推进：公共层（Result/BizException/JwtUtil）→ 数据访问层（BrandMapper/UsrUserMapper）→ 业务层（AuthServiceImpl，含 brand 多租户查找、BCrypt 校验、禁用/锁定检查、失败计数、JWT 签发 6 条业务规则）→ 接口层（SecurityConfig + AuthController）。前端分三层推进：项目骨架 → Axios 封装 + Redux authSlice → LoginPage.tsx 含 brand 下拉 + 用户名密码表单。
+
+**Tech Stack:** Spring Boot 3.x · Spring Security · JJWT 0.12.x · MyBatis-Plus 3.5.x · Flyway 10.x · MySQL 8.x · Vite · React 18 · Ant Design 5.x · Redux Toolkit · Axios · Vitest + @testing-library/react

+- `JwtProperties (@ConfigurationProperties("jwt"))` — `String secret`，`long accessTokenExpiry`（秒），`long refreshTokenExpiry`（秒）；加 `@EnableConfigurationProperties(JwtProperties.class)` 于 Application 或 Config 类
+- `JwtUtil (@Component)`：注入 JwtProperties

+- `@BeforeEach` 插入 brand 行：`sId='b-test-001', sNo='TST', sName='测试版', iIncrement=null`（自增），其余字段留 null
+- `@AfterEach` DELETE WHERE sNo='TST'
+- 测试方法 `findByNo_returnsCorrectBrand` — `new LambdaQueryWrapper<BrandEntity>().eq(BrandEntity::getSNo, "TST")` selectOne → sName == "测试版"

+- [ ] **Step 2: 实现 Entity + Mapper + MyBatisPlusConfig**
+  - 注意：Entity 字段名用 Java camelCase，`@TableField` 注解对应数据库实际列名（如 `@TableField("sBrandsId")` 或直接用 MyBatis-Plus 全局下划线转换——由于列名本身是驼峰，需关闭 `map-underscore-to-camel-case` 或手动 @TableField）
+

+**API shape:**
+- `LoginReqDTO` — `@NotBlank String brandNo`，`@NotBlank String username`，`@NotBlank String password`
+- `LoginVO` — `String accessToken`，`String refreshToken`，`long expiresIn`（固定值 86400），`UserInfoVO userInfo`
+  - `UserInfoVO (static inner class)` — `String userId`，`String username`，`String userType`，`String language`，`String brandId`
+- `AuthService` — `LoginVO login(LoginReqDTO req)`；`String refresh(String refreshToken)`；`List<BrandVO> getBrands()`
+- `AuthServiceImpl (@Service @Transactional)` — 注入 `BrandMapper`，`UsrUserMapper`，`JwtUtil`，`BCryptPasswordEncoder`
+
+**AuthServiceImpl.login 业务规则（按顺序）：**
+1. `brandMapper.selectOne(new LambdaQueryWrapper<BrandEntity>().eq(BrandEntity::getSNo, req.getBrandNo()))` → null → `throw new BizException(40100, "用户名或密码错误")`
+2. `userMapper.selectOne(new LambdaQueryWrapper<UsrUserEntity>().eq(UsrUserEntity::getSUsername, req.getUsername()).eq(UsrUserEntity::getSBrandsId, brand.getSId()))` → null → `throw new BizException(40100, "用户名或密码错误")`
+3. `user.getBIsDisabled() == 1` → `throw new BizException(40101, "账号已被禁用，请联系管理员")`
+4. `user.getTLockUntil() != null && user.getTLockUntil().isAfter(LocalDateTime.now())` → 计算 remainMinutes = `(int) Math.ceil(ChronoUnit.SECONDS.between(LocalDateTime.now(), user.getTLockUntil()) / 60.0)` → `throw new BizException(40102, "账号已被锁定，请 " + remainMinutes + " 分钟后重试")`
+5. `!passwordEncoder.matches(req.getPassword(), user.getSPasswordHash())` → `int newCount = user.getILoginFailCount() + 1`
+   - `newCount >= 5`: `LocalDateTime lockUntil = LocalDateTime.now().plusMinutes(30)`；`userMapper.update(null, new LambdaUpdateWrapper<UsrUserEntity>().eq(UsrUserEntity::getSId, user.getSId()).set(UsrUserEntity::getILoginFailCount, newCount).set(UsrUserEntity::getTLockUntil, lockUntil))` → `throw new BizException(40102, "账号已被锁定，请 30 分钟后重试")`
+   - `newCount < 5`: `userMapper.update(null, new LambdaUpdateWrapper<UsrUserEntity>().eq(UsrUserEntity::getSId, user.getSId()).set(UsrUserEntity::getILoginFailCount, newCount))` → `throw new BizException(40100, "用户名或密码错误")`
+6. 成功：`userMapper.update(null, new LambdaUpdateWrapper<UsrUserEntity>().eq(UsrUserEntity::getSId, user.getSId()).set(UsrUserEntity::getILoginFailCount, 0).set(UsrUserEntity::getTLockUntil, null).set(UsrUserEntity::getTLastLoginDate, LocalDateTime.now()))`；签发 tokens；返回 LoginVO
+
+- [ ] **Step 1: 写 7 个失败单元测试（AuthServiceTest — @ExtendWith(MockitoExtension.class)，mock BrandMapper/UsrUserMapper/JwtUtil/BCryptPasswordEncoder）**
+  - `login_brandNotFound_throws40100` — brandMapper.selectOne → null → BizException(40100)
+  - `login_userNotFound_throws40100` — brand 存在，userMapper.selectOne → null → BizException(40100)
+  - `login_accountDisabled_throws40101` — user.bIsDisabled=1 → BizException(40101)
+  - `login_accountLocked_throws40102WithRemainingMinutes` — user.tLockUntil=now+20min → BizException(40102)，message 含 "20 分钟"
+  - `login_wrongPassword_firstTime_throws40100AndIncrementsCount` — BCrypt 不匹配，iLoginFailCount=0 → 更新为 1，throw 40100
+  - `login_wrongPassword_5thTime_setsLockAndThrows40102` — BCrypt 不匹配，iLoginFailCount=4 → 更新为 5，设 tLockUntil，throw 40102
+  - `login_success_resetsCountAndReturnsTokens` — BCrypt 匹配 → reset count，issue tokens，返回 LoginVO
+
+- [ ] **Step 2: 实现 LoginReqDTO + LoginVO + AuthService + AuthServiceImpl.login()**
+  - `BCryptPasswordEncoder` 注入：在 Task 5 中同步创建 `BeanConfig.java`（`@Configuration @Bean BCryptPasswordEncoder passwordEncoder()`），使 Spring context（ApplicationContextTest）在 Task 5 之后仍能正常加载；SecurityConfig（Task 7）不重复声明此 Bean

+- 测试: `backend/src/test/java/com/example/erp/module/usr/AuthServiceTest.java`（追加 3 个测试方法）
+
+**API shape:**
+- `RefreshTokenReqDTO` — `@NotBlank String refreshToken`
+- `BrandVO` — `String sNo`，`String sName`
+- `AuthServiceImpl#refresh(String refreshToken) : String`
+  1. `Claims claims = jwtUtil.parseRefreshToken(refreshToken)` — 无效/过期自动抛 BizException(40103)
+  2. `String userId = claims.getSubject(); String brandId = claims.get("brandId", String.class)`
+  3. `UsrUserEntity user = userMapper.selectOne(new LambdaQueryWrapper<UsrUserEntity>().eq(UsrUserEntity::getSId, userId))` → null 或 `bIsDisabled=1` → throw BizException(40103, "Refresh Token 已失效，请重新登录")
+  4. 签发新 accessToken：`jwtUtil.generateAccessToken(user.getSId(), user.getSUsername(), user.getSUserType(), brandId)`；返回新 accessToken 字符串
+- `AuthServiceImpl#getBrands() : List<BrandVO>`
+  - `brandMapper.selectList(new QueryWrapper<BrandEntity>().select("sNo", "sName").orderByAsc("sName"))` → 映射为 BrandVO 列表
+
+- [ ] **Step 1: 写 3 个失败测试（追加到 AuthServiceTest）**
+  - `refresh_validRefreshToken_returnsNewAccessToken` — parseRefreshToken 成功，查库返回有效 user → generateAccessToken 被调用，返回新 token
+  - `refresh_invalidRefreshToken_throws40103` — parseRefreshToken 抛 BizException(40103)
+  - `getBrands_returnsListSortedByName` — brandMapper.selectList 返回 [b1, b2] → 结果 List<BrandVO> 包含对应 sNo/sName

+  - `jwtUtil.parseAccessToken(token)` → 设 `UsernamePasswordAuthenticationToken` 入 SecurityContextHolder
+  - token 无效 → 不设 context（Spring Security 后续返回 401）；请求路径匹配 `/api/auth/**` → 直接放行不解析
+- `AuthController (@RestController @RequestMapping("/api/auth") @RequiredArgsConstructor)`:

+- 版本 `Select`（label="公司/版本"，name="brandNo"）：组件 mount 时调 `getBrands()`，填充选项（value=sNo, label=sName）；defaultValue = sName=="标准版" 对应的 sNo；若无"标准版"则选第一项
+- 用户名 `Input`（label="用户名"，name="username"）：必填
+- 密码 `Input.Password`（label="密码"，name="password"）：必填
+- 提交按钮（text="登录"，`loading={loading}`）：防重复点击
+- 失败：`message.error(接口返回 message)`
+- 成功：`dispatch(setCredentials({accessToken, refreshToken, userInfo}))` → `navigate('/')`
+
+**LoginPage 内部数据流：**
+1. `useEffect(() => { getBrands().then(setBrandOptions) }, [])` — 挂载时获取 brand 列表
+2. `onFinish(values)` → `setLoading(true)` → `await login(values)` → `dispatch(setCredentials(...))` → `navigate('/')` → `finally setLoading(false)`
+
+- [ ] **Step 1: 写 2 个失败测试（LoginPage.test.tsx）**
+  - `renders_brandSelect_username_and_password_fields`
+    - render LoginPage（with Redux Provider + MemoryRouter + mock getBrands → [{sNo:"STD",sName:"标准版"}]）
+    - 断言：combobox（brand Select）存在，`getByPlaceholderText` 或 label "用户名" Input 存在，"密码" Input 存在，"登录" Button 存在
+  - `submit_withValidCredentials_dispatchesSetCredentials`
+    - mock `auth.login` 返回 `{accessToken:"at", refreshToken:"rt", expiresIn:86400, userInfo:{userId:"u1",username:"admin",userType:"超级管理员",language:"中文",brandId:"b1"}}`
+    - 填写 username + password，点击登录 → `store.getState().auth.accessToken == "at"`
+
+- [ ] **Step 2: 实现 LoginPage.tsx + 更新 App.tsx（/login 路由）**
+
+- [ ] **Step 3: 子会话运行 `npm run test -- --run`，确认所有前端测试（包括 authSlice + LoginPage）PASS**
+
+- [ ] **Step 4: Commit**
+  - `git commit -m "feat(usr): LoginPage brand selector + login form REQ-USR-004"`

+
+## 结论
+approve
+
+## Must-fix
+（无）
+
+## Nice-to-have
+- docs/05-API接口契约.md — GET /api/usr/users/staffs 和 GET /api/usr/users/permission-groups 两个接口未写入 docs/05，规格已标注「不在原始清单」但未补录，建议在 module-report 阶段补充
+- UserServiceImpl.java — CLAUDE.md §编码行为约束 第 4 条要求关键方法带 REQ-USR-001 注释标签，当前后端文件均缺失（仅 PermButton.tsx 有一处）
+
+## 反例 / 测试覆盖缺口
+全部三轮 must-fix 已正确修复并通过 41 用例验证。实现与 spec 完全对齐：权限校验、唯一性检查、EMPLOYEE_NOT_FOUND=40001、批量 insert(Collection)、@Transactional 边界、UserPrincipal 基础设施均符合规格。两个 nice-to-have 均为文档/注释层面的缺失，不影响功能正确性。

+# Review: REQ-USR-002 — round 2
+
+## 结论
+approve
+
+## Must-fix
+（无）
+
+Round 1 全部 must-fix 已正确修复：
+- M1 ✓ `updateUser_selfAdminKeepType_doesNotThrow` 测试已添加（含 userMapper.update stub）
+- M2 ✓ `UserUpdateReqDTO` 已添加 @NotBlank/@Pattern/@NotNull 校验注解
+- M3 ✓ `UserFormDrawer.InitialData` 已添加 permGroupIds 字段，useEffect 用 `?? []` 初始化
+- M4 ✓ `UserListItemVO` 已添加 bCanEditDoc，mapper SELECT 已加列，UserListPage 传真实值
+
+## Nice-to-have
+- backend/.../vo/UserUpdateRespVO.java — updatedAt 建议添加 @JsonFormat(pattern="yyyy-MM-dd HH:mm:ss") 符合 docs/04 § 3.3 规范
+- frontend/src/test/UserListPage.test.tsx:106 — editMode_submit_callsUpdateUser 可补 toHaveBeenCalledWith('u1', ...) 断言 userId 参数正确
+- frontend/src/pages/usr/UserListPage.tsx:121-128 — initialData 未传 permGroupIds（因列表 API 无此字段），与规格 line 103 说明一致，属有意为之，建议加注释说明
+
+## 反例 / 测试覆盖缺口
+- controller 层 BizException 40300/40400/40301 → 错误码 JSON 映射缺测试（低风险，handler 已在 createUser 路径覆盖）
+- happy-path 未用 ArgumentCaptor 断言 bCanEditDoc/bIsDisabled 映射为正确 int 值（低风险）

+
+## Nice-to-have
+- backend/src/main/java/com/example/erp/module/usr/controller/UserController.java:35-50 — docs/05 声明了 Permission: usr:query，但当前 SecurityConfig 仅做鉴权（authenticated），未启用 @PreAuthorize，属跨切面 REQ 的存量缺口，非本 REQ 引入
+- backend/src/main/java/com/example/erp/common/response/Result.java:19 — docs/04 § 1.3 示例写 code:0，实际实现与 docs/05 一致为 200；docs/04 示例是历史遗留，可单独 docs commit 修正
+- backend/src/main/resources/mapper/UsrUserMapper.xml:29,43 — staffName/department equals 分支未加 IS NULL OR，因为 equals '部门名' 语义上不应匹配无职员用户，行为正确但可补注释说明
+- backend/src/test/java/com/example/erp/module/usr/UserControllerTest.java:109 — getUsers_withToken_returns200 未用 ArgumentCaptor 验证五个参数均正确转发给 service
+
+## 反例 / 测试覆盖缺口
+- 无 XML 动态查询路径（含/不含/等于、disabled 是否、lastLoginDate DATE 过滤、pageSize cap）的集成/切片测试；mapper 被 mock 后 XML 逻辑未被单元覆盖
+- UserControllerTest 未断言响应中不含 sPasswordHash / iLoginFailCount / tLockUntil
+- 前端测试未覆盖翻页 onChange 回调（load 以正确页码调用）
