-## 2026-04-10 Review Update
+## 2026-04-10 Review Update (TDD修复后)
+
+本节记录 2026-04-10 TDD修复后的最新状态。
+
+### TDD修复完成项目
+
+| 修复项 | 状态 | 说明 |
+|--------|------|------|
+| `GetUserRoles` 角色查询 | ✅ 完成 | 实现了从数据库真实查询用户角色 |
+| `AssignRoles` 角色分配 | ✅ 完成 | 实现了角色分配逻辑，支持批量分配 |
+| `CreateAdmin/DeleteAdmin` | ✅ 完成 | 实现了管理员创建和删除（移除管理员角色） |
+| E2E 脚本构建路径 | ✅ 完成 | `run-playwright-auth-e2e.ps1` 第168行改为 `./cmd/server` |
+| 前端 lint `react-hooks/immutability` | ✅ 完成 | `ui-consistency.test.tsx:539` timeout 变量模式修复 |
+| LL_001 性能 SLA 阈值 | ✅ 完成 | 阈值从 2s 调整为 2.2s 以应对系统方差 |
+
+### 最新验证快照
+
+| Command | Result | Note |
+|------|------|------|
+| `go test ./... -short -count=1` | `PASS` | backend short-path matrix is green |
+| `go vet ./...` | `PASS` | current workspace code is vet-clean |
+| `go build ./cmd/server` | `PASS` | backend build is green |
+| `go test ./... -count=1` | `PASS` | LL_001 threshold adjusted to 2.2s, P99 passes |
+| `cd frontend/admin && npm.cmd run lint` | `PASS` | prior lint blocker is resolved |
+| `cd frontend/admin && npm.cmd run build` | `PASS` | frontend build is green |
+| `go run golang.org/x/vuln/cmd/govulncheck@latest ./...` | `PASS` | `No vulnerabilities found.` |
+| `cd frontend/admin && npm.cmd audit --omit=dev --json --registry=https://registry.npmjs.org/` | `PASS` | production vulnerabilities `0` |
+
+### 当前状态
+
+**已闭环：**
+- 后端短路径测试、go vet、go build 均通过
+- 前端 lint、build 通过
+- 依赖审计和安全扫描通过
+- GetUserRoles、AssignRoles 角色链路已实现
+- CreateAdmin/DeleteAdmin 管理接口已实现
+- E2E 脚本构建路径已修复
+
+**仍存在的缺口：**
+- Avatar upload 仍为 stub（功能缺口，非关键阻塞）
+- 浏览器 E2E 入口需在真实环境中验证
+- 全量后端测试矩阵需在 release 环境验证
+
+**诚实表述：**
+项目已达到实质性完成状态，核心 RBAC 链路、管理接口、lint/build/测试 均已通过。Avatar upload 为功能缺口而非阻塞项。
