+# Middleware Test Backfill Phase 1 Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Raise confidence in the backend request chain by backfilling focused unit tests for the auth, RBAC, error recovery, and trace ID middleware.
+
+**Architecture:** Extend the existing `internal/api/middleware` test suite with `gin` + `httptest` behavior tests. Keep the tests at the middleware boundary by using lightweight stubs for auth dependencies instead of bringing in service or repository integration.
+
+**Tech Stack:** Go, Gin, `net/http/httptest`, existing JWT manager, package-local test helpers
+
+---
+
+### Task 1: Add auth middleware regression tests
+
+**Files:**

+```go
+func TestAuthMiddleware_RequiredRejectsMissingToken(t *testing.T) {}
+func TestAuthMiddleware_RequiredRejectsInvalidToken(t *testing.T) {}
+func TestAuthMiddleware_RequiredRejectsBlacklistedToken(t *testing.T) {}
+func TestAuthMiddleware_RequiredRejectsInactiveUser(t *testing.T) {}

+Expected: FAIL because the test file does not exist yet.
+
+- [ ] **Step 3: Add the minimal behavior tests**
+
+```go
+router.Use(func(c *gin.Context) {
+	c.Set(ContextKeyRoleCodes, []string{"viewer"})
+	c.Set(ContextKeyPermissionCodes, []string{"user:read"})

+
+- [ ] **Step 3: Add assertions around headers, JSON payloads, and panic recovery**
+
+```go
+if got := GetTraceID(c); got != expected {
+	t.Fatalf("GetTraceID() = %q, want %q", got, expected)
+}
+```

+
+```yaml
+groups:
+  - name: user-management
+    rules:
+      # 服务不可用
+      - alert: ServiceDown
+        expr: up{job="user-management"} == 0

+
+---
+
+## 4. Grafana 看板
+
+建议导入以下看板配置：
+
+### 4.1 核心看板指标
+
+**Overview 看板**：
+- 请求率（QPS）
+- P50/P90/P99 延迟

+
+---
+
+## 5. 日志关键字监控
+
+建议在日志收集系统（如 Loki/ELK）中配置以下关键字告警：
+
+| 关键字 | 严重程度 | 说明 |
+|--------|----------|------|
+| `auth: increment login attempts failed` | warning | Redis/L1 缓存不可用 |

+| `cache.Set failed` | warning | 缓存写入失败 |
+| `failed to send email` | warning | 邮件发送失败 |
+
+---
+
+## 6. 健康检查脚本示例
+
+```bash
+#!/bin/bash
+# health_check.sh — 服务健康检查脚本
+
+HEALTH_URL="http://localhost:8080/health"
+READY_URL="http://localhost:8080/health/ready"
+METRICS_URL="http://localhost:8080/metrics"
+
+check_endpoint() {
+    local url=$1
+    local name=$2
+    local status=$(curl -s -o /dev/null -w "%{http_code}" "$url")
+
+    if [ "$status" -eq 200 ]; then
+        echo "[OK] $name: $status"
+        return 0
+    else
+        echo "[FAIL] $name: $status"
+        return 1
+    fi
+}
+
+# 执行检查
+failed=0
+
+check_endpoint "$HEALTH_URL" "Health" || failed=$((failed + 1))
+check_endpoint "$READY_URL" "Ready" || failed=$((failed + 1))
+
+# 检查 Prometheus 指标端点
+status=$(curl -s -o /dev/null -w "%{http_code}" "$METRICS_URL")
+if [ "$status" -eq 200 ]; then
+    echo "[OK] Metrics: $status"
+else
+    echo "[WARN] Metrics: $status"
+fi
+
+# 检查数据库连接（通过日志）
+if grep -q "database opened" logs/app.log 2>/dev/null; then
+    echo "[OK] Database: connected"
+else
+    echo "[FAIL] Database: not connected"
+    failed=$((failed + 1))
+fi
+
+exit $failed
+```
+
+---
+

+# 用户操作手册
+
+本文档面向普通用户，描述用户管理系统的使用方法。
+
+---
+
+## 1. 注册与登录
+
+### 1.1 注册账号
+
+**路径**：`POST /api/v1/auth/register`
+
+```json
+{
+  "username": "yourname",
+  "password": "SecurePass123!",
+  "email": "you@example.com"
+}
+```
+
+**密码要求**：
+- 最少 8 位
+- 必须包含大写字母
+- 必须包含小写字母
+- 必须包含数字
+- 必须包含特殊字符（`!@#$%^&*` 等）
+
+### 1.2 登录
+
+**路径**：`POST /api/v1/auth/login`
+
+```json
+{
+  "account": "yourname",
+  "password": "SecurePass123!",
+  "device_id": "your-device-id"
+}
+```
+
+返回的响应中包含：
+- `access_token` — API 访问令牌（内存存储，不要持久化）
+- `refresh_token` — 刷新令牌（用于续期 access_token）
+- `expires_in` — access_token 有效期（秒）
+
+### 1.3 登录安全验证
+
+如果账户开启了 TOTP 两步验证，登录后会返回：
+
+```json
+{
+  "requires_totp": true,
+  "temp_token": "xxx",
+  "user_id": 123
+}
+```
+
+此时需要完成 TOTP 验证：
+
+**路径**：`POST /api/v1/auth/login/totp-verify`
+
+```json
+{
+  "user_id": 123,
+  "code": "123456",
+  "device_id": "your-device-id",
+  "temp_token": "xxx"
+}
+```
+
+---
+
+## 2. 账户安全
+
+### 2.1 修改密码
+
+**路径**：`PUT /api/v1/auth/password`
+
+```json
+{
+  "old_password": "OldPass123!",
+  "new_password": "NewPass456!"
+}
+```
+
+**注意**：修改密码会使除当前设备外的所有会话失效。
+
+### 2.2 忘记密码
+
+**路径**：`POST /api/v1/auth/password/forgot`
+
+```json
+{
+  "email": "you@example.com"
+}
+```
+
+系统会向邮箱发送重置链接。
+
+### 2.3 设置 TOTP 两步验证
+
+**步骤 1**：请求 TOTP 绑定信息
+**路径**：`POST /api/v1/auth/totp/setup`
+
+返回二维码和密钥。使用 Google Authenticator 或其他 TOTP 应用扫描。
+
+**步骤 2**：启用 TOTP
+**路径**：`POST /api/v1/auth/totp/enable`
+
+```json
+{
+  "code": "123456"
+}
+```
+
+启用后，下次登录需要输入 TOTP 验证码。
+
+### 2.4 禁用 TOTP
+
+**路径**：`POST /api/v1/auth/totp/disable`
+
+```json
+{
+  "code": "123456"
+}
+```
+
+### 2.5 恢复码
+
+首次启用 TOPT 时，系统会提供一组恢复码。
+
+**用途**：当 TOTP 设备丢失时，使用恢复码恢复登录。
+
+**保存建议**：将恢复码打印或手写保存到安全位置，切勿截图或保存到云端。
+
+---
+
+## 3. 设备管理
+
+### 3.1 查看我的设备
+
+**路径**：`GET /api/v1/devices`
+
+返回当前账户下所有已登录设备列表。
+
+### 3.2 查看信任设备
+
+**路径**：`GET /api/v1/devices/trusted`
+
+返回已标记为信任的设备列表。信任设备在有效期内免 TOTP 验证。
+
+### 3.3 信任当前设备
+
+**路径**：`POST /api/v1/devices/trust`
+
+将当前设备标记为信任设备。
+
+**注意**：需要在设备详情中查看设备 ID。
+
+### 3.4 取消设备信任
+
+**路径**：`DELETE /api/v1/devices/:id/trust`
+
+### 3.5 登出其他设备
+
+**路径**：`POST /api/v1/devices/logout-others`
+
+将除当前设备外的所有其他设备登出。
+
+Header 中需要指定当前设备：`X-Device-ID: your-device-id`
+
+---
+
+## 4. 个人资料
+
+### 4.1 查看个人资料
+
+**路径**：`GET /api/v1/auth/userinfo`
+
+### 4.2 更新个人资料
+
+**路径**：`PUT /api/v1/users/profile`
+
+```json
+{
+  "nickname": "Your Name",
+  "phone": "13800138000"
+}
+```
+
+### 4.3 上传头像
+
+**路径**：`POST /api/v1/users/:id/avatar`
+
+支持的格式：JPEG、PNG、GIF、WebP
+最大文件大小：5MB
+
+---
+
+## 5. Token 刷新
+

+
+```json
+{
+  "refresh_token": "your_refresh_token"
+}
+```
+
+返回新的 access_token 和 refresh_token。
+
+---
+
+## 6. 账户注销
+
+**路径**：`DELETE /api/v1/users/account`
+
+注销后所有数据将被永久删除，不可恢复。
+
+---
+
+## 7. API 认证
+
+所有需要认证的 API，在请求 Header 中添加：
+
+```
+Authorization: Bearer <access_token>
+```
+
+示例：
+
+```bash
+curl http://localhost:8080/api/v1/auth/userinfo \
+  -H "Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..."
+```

+# Prelaunch Navigation And Batch Delete Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Fix the release-blocking admin mobile navigation browser path and strengthen bulk-delete confirmation on the users admin page.
+
+**Architecture:** Keep the product changes minimal and local to the admin frontend. Make mobile drawer state transitions explicit in `AdminLayout`, harden the supported E2E scenario around the real drawer surface, and upgrade `UsersPage` bulk delete from a lightweight pop confirmation to a stronger modal confirmation without changing backend APIs.
+
+**Tech Stack:** React 18, Ant Design, React Router, Vitest, Playwright CDP runner.
+
+---
+
+### Task 1: Capture the failing browser evidence
+
+**Files:**
+- Modify: none
+
+- [ ] Run `cd frontend/admin && $env:E2E_SCENARIOS='desktop-mobile-navigation'; npm.cmd run e2e:full:win`.
+- [ ] Record the exact failing step and whether the drawer fails to open, the selector fails to resolve, or navigation fails after selection.
+- [ ] Do not change product code until the failure mode is confirmed.
+
+### Task 2: Add the AdminLayout regression first
+
+**Files:**
+- Modify: `frontend/admin/src/layouts/AdminLayout/AdminLayout.test.tsx`
+- Modify: `frontend/admin/src/layouts/AdminLayout/AdminLayout.tsx`
+
+- [ ] Add a failing test that switches from desktop to mobile, opens the menu, navigates through the drawer, and proves the drawer closes deterministically after selection.
+- [ ] Run `cd frontend/admin && npm.cmd run test:run -- src/layouts/AdminLayout/AdminLayout.test.tsx`.
+- [ ] Confirm the new assertion fails for the current implementation before fixing the layout.
+
+### Task 3: Fix mobile drawer state and harden the browser scenario
+
+**Files:**
+- Modify: `frontend/admin/src/layouts/AdminLayout/AdminLayout.tsx`
+- Modify: `frontend/admin/scripts/run-playwright-cdp-e2e.mjs`
+
+- [ ] Replace toggle-based mobile drawer state transitions with explicit open and close handlers.
+- [ ] Keep desktop collapse behavior unchanged.
+- [ ] Narrow browser selectors and waits so the scenario checks the intended mobile button and the open drawer content.
+- [ ] Re-run `cd frontend/admin && $env:E2E_SCENARIOS='desktop-mobile-navigation'; npm.cmd run e2e:full:win`.
+
+### Task 4: Add the UsersPage regression first
+
+**Files:**
+- Modify: `frontend/admin/src/pages/admin/UsersPage/UsersPage.test.tsx`
+- Modify: `frontend/admin/src/pages/admin/UsersPage/UsersPage.tsx`
+
+- [ ] Add a failing test that selects users, triggers bulk delete, verifies no delete happens on the first lightweight action alone, and confirms the API call only occurs after the stronger explicit confirmation.
+- [ ] Run `cd frontend/admin && npm.cmd run test:run -- src/pages/admin/UsersPage/UsersPage.test.tsx`.
+- [ ] Confirm the new assertion fails for the current implementation before changing the page.
+
+### Task 5: Implement stronger bulk-delete confirmation
+
+**Files:**
+- Modify: `frontend/admin/src/pages/admin/UsersPage/UsersPage.tsx`
+
+- [ ] Replace the direct `Popconfirm` bulk-delete path with a stronger confirmation modal flow.
+- [ ] Keep the existing self-delete guard and empty-selection guard.
+- [ ] After confirmation, keep existing success behavior: call `batchDelete`, clear selection, and refresh the list.
+- [ ] Re-run `cd frontend/admin && npm.cmd run test:run -- src/pages/admin/UsersPage/UsersPage.test.tsx`.
+
+### Task 6: Verify the affected frontend surface
+
+**Files:**
+- Modify: only if verification reveals another real defect
+
+- [ ] Run `cd frontend/admin && npm.cmd run test:run -- src/layouts/AdminLayout/AdminLayout.test.tsx src/pages/admin/UsersPage/UsersPage.test.tsx`.
+- [ ] Run `cd frontend/admin && npm.cmd run lint`.
+- [ ] Run `cd frontend/admin && npm.cmd run build`.
+- [ ] Re-run `cd frontend/admin && $env:E2E_SCENARIOS='desktop-mobile-navigation'; npm.cmd run e2e:full:win`.
+- [ ] Report the results exactly as observed, including any remaining risk if full-suite E2E is not rerun in this turn.

+# Prelaunch Navigation And Batch Delete Design
+
+**Date:** 2026-05-10
+
+**Goal:** Remove the release-blocking `desktop-mobile-navigation` browser failure and strengthen the admin users batch-delete confirmation flow identified in the 2026-05-10 prelaunch report.
+
+## Scope
+
+- Stabilize the admin mobile navigation behavior used by the supported Playwright CDP browser gate.
+- Keep the `desktop-mobile-navigation` scenario as a real product verification path instead of weakening it into a runner-only smoke check.
+- Strengthen the `UsersPage` batch-delete confirmation so destructive bulk actions require clearer intent than the current single pop confirmation.
+- Add focused frontend regression coverage for both changes.
+
+## Non-Goals
+
+- No redesign of the admin layout visual system.
+- No change to backend user deletion APIs or authorization rules.
+- No expansion of the prelaunch recommendations unrelated to today's release blockers, such as password strength hints, dashboard charts, or OAuth button loading states.
+
+## Current Findings
+
+### 1. Mobile navigation
+
+- The admin layout keeps mobile drawer state in a toggle-style setter:
+  - `setMobileDrawerOpen(!mobileDrawerOpen)`
+- The same toggle function is used for both explicit open actions and drawer close callbacks.
+- The supported browser scenario switches from desktop to mobile in the same logged-in session, then immediately depends on the drawer opening reliably.
+- This combination creates avoidable state ambiguity during viewport transitions and makes the release-blocking browser path fragile.
+
+### 2. Batch delete confirmation
+
+- `UsersPage` already wraps bulk delete in a single `Popconfirm`.
+- That means the prelaunch issue is not "missing confirmation" but "confirmation is too weak for a destructive bulk operation."
+- The strengthened flow should make the count explicit and require a second, clearer confirmation step before the delete request is sent.
+
+## Approach
+
+### Mobile navigation
+
+- Replace toggle-style drawer state transitions with explicit intent helpers:
+  - open drawer
+  - close drawer
+- Ensure mobile menu selection closes the drawer deterministically.
+- Keep desktop collapse behavior unchanged.
+- Tighten the browser scenario selectors and waits around the mobile menu button and open drawer so the test verifies the intended surface instead of a broad Ant Design selector.
+
+### Batch delete confirmation
+
+- Keep the existing selection toolbar and bulk action entry point.
+- Replace the direct destructive `Popconfirm -> delete` path with a stronger confirmation modal step.
+- The modal must:
+  - show the selected count clearly
+  - repeat that the action is irreversible
+  - require explicit user confirmation before calling `batchDelete`
+- Preserve existing safeguards:
+  - no-op when nothing is selected
+  - block deleting the current logged-in user
+
+## Test Strategy
+
+### Admin layout
+
+- Add a frontend regression test proving that mobile drawer open/close behavior remains stable after switching from desktop to mobile in the same render path.
+- Keep the existing layout behavior test coverage aligned with the real drawer flow.
+
+### Users page
+
+- Add a failing regression test for the strengthened bulk-delete flow:
+  - selecting rows does not delete immediately
+  - destructive API call happens only after the second explicit confirmation
+  - success state clears selection and refreshes data
+
+### Browser verification
+
+- Reproduce and then rerun the supported scenario:
+  - `cd frontend/admin && $env:E2E_SCENARIOS='desktop-mobile-navigation'; npm.cmd run e2e:full:win`
+
+## Verification
+
+- Targeted browser check:
+  - `cd frontend/admin && $env:E2E_SCENARIOS='desktop-mobile-navigation'; npm.cmd run e2e:full:win`
+- Targeted frontend tests:
+  - `cd frontend/admin && npm.cmd run test:run -- src/layouts/AdminLayout/AdminLayout.test.tsx src/pages/admin/UsersPage/UsersPage.test.tsx`
+- Frontend quality gate for affected area:
+  - `cd frontend/admin && npm.cmd run lint`
+  - `cd frontend/admin && npm.cmd run build`
