+
+## 🎯 一句话总览
+
+**项目状态**:**v0.5.6-dev-tooling 完成**,本地 4 端 dev 链路全通(Mock 企微 OAuth + 3 个新 migration + 1 个 decorator bug 修复)。
+**当前主线**:**等用户决策要不要上生产**(生产 3 个 migration + 1 个 bug 修复可上,7 个 dev 改动留在本地)。
+**待回复**:#83 OTM 是什么 / 跟项目什么关系。
+
+---
+
+## 🟢 正在做(in_progress,1 件)
+
+| # | 任务 | 我做什么 | 你做什么 | 完成定义 |
+|---|---|---|---|---|
+| #90 | 后端 pytest 测试套件 | 补 token_service / scoring_service 等 | 等结果 | 20+ 测试通过 |
+

+
+## 🔴 P0 必做(下一个 sprint)
+
+| # | 任务 | 重要程度 | 说明 |
+|---|---|---|---|
+| #48 | v1.0 收窄 set_real_ip_from | 🔴 P0 | 现 allow 0.0.0.0/0 是临时方案,正式上线前必须改精确代理 IP |
+| #81 | v0.6.0 敏感词检测 + 语气优化 | 🔴 P0 | 下一个版本的核心功能 |
+| #80 | v0.5.4 应急页 nginx 路由 + 部署 | 🔴 P0 | 当前生产缺路由,功能上了但用户访问不到 |
+
+---
+
+## 🟡 P1 重要(看时间做)
+
+| # | 任务 | 说明 |
+|---|---|---|
+| #73 | 修后端文件未真正覆盖 | `yes | cp -f` 路径,部署时偶尔没生效 |
+| #86 | 排查流程图零依赖部分 review + 文档化 | 把 Mermaid 流程图从代码里剥离成可读文档 |
+| #88 | 管理后台 RBAC 角色权限 | 管理后台细粒度角色权限(大功能,2-3 天) |
+| #83 | 澄清"OTM 跟项目关系" | **我在这等你回答**:OTM 是什么?需要对接吗? |
+

+
+## 🟢 P2 / 等用户决策
+
+| # | 任务 | 卡在哪 |
+|---|---|---|
+| **🆕 服务器更新?** | 把今天的 3 个 migration + 1 个 bug 修复部署到生产 v0.5.6 | **等你看这份看板后拍板** |
+| #31 | 推 docker 镜像到生产 registry | 等你确认要走哪条路(自建 Harbor / 阿里云 / 别的) |
+| #43 | 配置 HTTPS | 等域名备案完成 + 证书到位 |
+| #53 | 用户在企微验证 /itportal/ | 等你去企微点一点 |

+
+## ✅ 最近搞定(给你信心)
+
+### 2026-06-16(今天)
+
+#### 🛠️ Dev 环境(本地链路全通)
+
+- ✅ **本地 dev 4 端链路跑通**(#89-92):
+  - backend (8000) + h5 (5174) + agent (5173) + admin (5175) + portal (5176) 全起
+  - Mock 企微 OAuth 全通(`/api/dev/login` 给 token)
+  - portal → H5 / 坐席 / 管理员 跳转正常
+- ✅ **修了 3 个 dev 启动坑**:
+  1. `pydantic==2.7.5` → `2.7.4`(2.7.5 被 PyPI yank)
+  2. docker-compose 加 `PYTHONPATH=/app`(alembic 1.13+ 不再默认 prepend cwd)
+  3. dev 启动必须用 `--env-file .env.dev`(根 `.env` 冲突)
+
+#### 🐛 Bug 修复
+
+- ✅ **#93 修 portal dev 模式跳错端口**:`import.meta.env.DEV` 判断,生产走相对路径,dev 走完整 URL
+- ✅ **#97 修 require_role 装饰器**:`@wraps` 让 FastAPI 看到 `__wrapped__` 签名,Depends 未被解析 → `current_user` 实际是 Depends 对象。用 `inspect` 合并 signature + 手动设 `wrapper.__signature__` 修
+- ✅ **#99 dev 模式短路企微推送**:避免 `.env.dev` 用 `dev_corp_id_xxxxx` 调企微 API 返 `invalid corpid` 噪音
+
+#### 🗃️ 数据库 migration(3 个)
+
+- ✅ **#94 alembic 010**:加 `agents.otp_secret` + `agents.otp_enabled`
+- ✅ **#94 alembic 011**:加 `conversations.impact_scope` + `is_blocking` + `emotion_state`(用户坐席发消息 500 的真因)
+- ✅ **#96 alembic 012**:加 `conversations.dify_conversation_id` + `employees.it_level` + `it_level_source` + `notes`
+
+#### 🛡️ 防错工具(留底用)
+
+- ✅ **#95 dev-check-schema-drift.ps1**:对比 SQLAlchemy 模型 vs Postgres schema,漂移 exit 1。以后模型加字段忘 migration 一跑就发现(用 docker exec,免去 Python 依赖)
+
+#### 📋 其他
+
+- ✅ **#68 H5 空白页闪一下**:dev 模式验证不再白屏(生产未复测)
+
+### 历史(选重点)
+
+- ✅ v0.5.5:应急页 v0.5.4 + 移除 IT 设备升级 + admin 登录修复 + 内容审核架构
+- ✅ v0.5.3:重打后端部署包(5 IT + 2 HR + 1 行政 + 1 财务 = 9 条)
+- ✅ v0.5.6-dev-tooling 已 tag + push gitea(本地 dev 工具集)
+- ✅ messages.id varchar=UUID SQL bug 修了(#60)+ 10 个回归测试通过
+- ✅ nginx /api/admin/ 和 /itadmin/ 修复 403/allow(#57)
+
+---
+
+## 🚀 怎么跑起来(3 步)
+
+### 1. 后端 dev(已经在跑 ✅)
+
+```powershell
+cd D:\资料\03-项目开发\wecom_it_smart_desk-claude
+docker compose -f docker-compose.dev.yml --env-file .env.dev up -d
+curl http://localhost:8000/api/dev/health
+```
+
+### 2. 前端 dev(已经在跑 ✅)
+
+```powershell
+# 一次性装 4 个前端依赖(已装好)
+.\scripts\dev-frontend-install.ps1
+
+# 之后:一起起所有前端
+.\scripts\dev-frontend-start.ps1
+# 单独停:.\scripts\dev-frontend-start.ps1 -Stop
+```
+
+### 3. 浏览器验证
+
+- portal:http://localhost:5176/itportal/select
+- H5:http://localhost:5174/itdesk/
+- 坐席:http://localhost:5173/itagent/
+- 管理员:http://localhost:5175/itadmin/

+## 📌 怎么读这份文档
+
+**你是运维小白,不需要懂代码**。看这个文件就能 1 分钟懂:
+
+1. **"现在在干嘛?"** → 看「正在做」表
+2. **"接下来要干嘛?"** → 看「P0 必做」表
+3. **"我需要做什么?"** → 看「正在做」表里的「你做什么」列
+4. **"今天有啥进展?"** → 看「最近搞定」

+
+## 🤖 Claude 怎么帮你
+
+每次开新 session 我会:
+
+1. **第一件事**:读这个文件 + TaskList,告诉你"上次到这了"
+2. **完成一件重要事**:更新这个文件(改状态、加完成项)
+3. **遇到阻塞**:写在「P2 / 等用户决策」里,等你回话
+4. **新需求进来**:跟当前 in_progress 比较,看是**接着做**还是**并行加**(参考你的"并行处理"反馈)

+    - qrcode:ticket:{ticket}   → {created_at, expires_at}, TTL 120s
+    - qrcode:scan:{ticket}     → {employee_id, name, scanned_at}, TTL 120s
+    - qrcode:confirm:{ticket}  → {token, confirmed_at, roles}, TTL 60s

+  不动 User / Agent 模型(MFA 字段留给 Phase 2.1)。
+  不动 auth2fa.py(SMS 备用通道保留)。
+
+为什么仍然生成这个 migration 文件:
+  1. alembic 版本链不能断,021 → 022 必须存在(后续 023+ 需要接续)
+  2. 标记 Phase 1.1 上线,方便运维追溯和回滚标记
+  3. upgrade()/downgrade() 都是空操作,因为没有 schema 变更
+
+运维注意事项:
+  - 该 migration 不需要执行 SQL(已注释),但需要"alembic stamp 022"让 alembic_version 表对齐
+  - 如果未来扫码登录要持久化历史记录(审计/防滥用),再追加 023_qrcode_audit.py 加 qrcode_login_logs 表

+# nginx access_log 脱敏脚本 — 不再记录 Authorization/Cookie 等敏感字段
+# =============================================================================
+# 背景(2026-06-21 评审):
+#   当前 nginx 默认 access_log 格式包含 $http_authorization, $http_cookie,
+#   这些字段含用户 token、session cookie,直接落盘到 /var/log/nginx/access.log。
+#   任何能读该日志的运维都能冒充任意用户(严重安全漏洞)。
+#
+# 修复方案(对应 P1 合规):
+#   1. 自定义 log_format "secure" — 不含 Authorization/Cookie/Set-Cookie
+#   2. access_log 引用 "secure" 格式
+#   3. 部署步骤: 在 nginx.conf http{} 块中插入下面的 log_format,
+#      然后把 access_log 行的格式从默认改成 "secure"。
+#
+# 用法:
+#   1. 在堡垒机上编辑 nginx.conf (宿主机路径或 docker exec 进容器改):
+#      docker exec -it wecom_it_nginx vi /etc/nginx/nginx.conf
+#   2. 把本脚本输出的 "SECURE LOG_FORMAT 块" 插入到 http {} 块顶部
+#   3. 把所有 access_log 行的格式参数从默认改成 "secure",例如:
+#      access_log /var/log/nginx/access.log secure;
+#   4. nginx -t && nginx -s reload
+#   5. 验证: curl -I https://... 看新日志是否含 "Bearer xxx"(不应该)
+#
+# ⚠️ 重要: 不要直接覆盖容器内 nginx.conf! bind mount RO 的话 docker cp 是假成功
+# 陷阱回顾: backend/.claude/memory/feedback/docker-cp-readonly-bind-mount-fake-success.md

+#   $http_cookie         — Session cookie,直接可劫持
+#   $sent_http_set_cookie — 服务端下发的 session
+#
+# 默认 combined 格式: '$remote_addr - $remote_user [$time_local] '

+# 部署手册:扫码登录 + OTP 二次认证(Phase 1+2)
+
+> 创建:2026-06-21
+> 适用版本:v0.7.0+ (Phase 1+2)
+> 部署顺序:后端 → 前端 4 端 → nginx → 数据库 migration → 验收
+
+---
+
+## 🎯 部署目标
+
+从 v0.6.x 的"企微 OAuth + SMS 2FA"升级到 v0.7.0 的"扫码登录 + OTP TOTP + SMS 备用"。
+
+涉及后端变更:
+- 新增 `/api/auth_qrcode/*` 4 个端点(扫码登录)
+- 新增 `/api/mfa/*` 6 个端点(OTP 二次认证)
+- 新增 `/api/admin/mfa/reset/{employee_id}`(管理员重置)
+- 新增 `/api/admin/high-risk/*` 演示端点 + require_high_risk_otp 守卫
+- 新增 2 个数据库字段: `users.mfa_secret`, `users.mfa_enabled`, `users.mfa_bound_at`, `users.mfa_last_verified_at`
+
+涉及前端变更:
+- frontend-agent:Login.vue 重写(扫码 UI)+ 新增 MfaBind.vue + useHighRiskOtp
+- frontend-portal:新增 QrcodeLogin.vue + 默认路由
+- frontend-admin:新增 MfaManage.vue(管理员 MFA 重置 UI)
+- frontend-h5:**不变**(仍走企微 OAuth)
+
+涉及 nginx 变更:
+- `/itportal/` 新增 location(扫码入口)
+- 其余 4 个 location 已有,配置按 docs/NGINX-DOMAIN-ROUTING.md
+
+---
+
+## 📋 部署前检查
+
+### 1. 后端镜像依赖
+
+`backend/requirements.txt` 必须包含:
+```
+pyotp==2.9.0          # TOTP 生成
+qrcode[pil]==7.4.2    # 二维码生成
+redis==5.0.7          # 已存在
+```
+
+### 2. 数据库迁移文件
+
+确认以下 migration 已存在:
+- `backend/alembic/versions/023_mfa_fields.py`(加 4 个 MFA 字段)
+- `backend/alembic/versions/024_*.py`(可选:其他变更)
+
+### 3. 配置文件
+
+`backend/.env` 确认:
+```bash
+# 新增(扫码登录)
+WECOM_OAUTH_REDIRECT_URI=https://itsupport.servyou.com.cn/itportal/qrcode-callback
+WECOM_CORP_ID=ww1234567890abcdef
+WECOM_AGENT_ID=1000002
+
+# 已有(OTP)
+SMS_2FA_ENABLED=true  # 蜂鸟 SMS 备用通道
+```
+
+### 4. 域名 / DNS
+
+- `itsupport.servyou.com.cn`(主域名,已有)
+- 子路径:`/itportal/` `/itagent/` `/itadmin/` `/itdesk/`(同一域名,nginx 分发)
+- 证书:`itsupport.servyou.com.cn.crt`(公司统一管理)
+
+---
+
+## 🚀 部署步骤
+
+### 步骤 1:部署后端(注意 RO bind mount)
+
+```bash
+# 1. 上传新 backend 包到堡垒机
+scp backend-v070-p1.tar.gz user@bastion:/tmp/
+
+# 2. 通过堡垒机 PuTTY(不用 ssh -J)登录生产服务器
+# 参考:feedback-putty-not-openssh.md
+
+# 3. 解压并复制到 backend 目录(走宿主机路径,避开 RO bind mount 陷阱)
+cd /opt/wecom-it-desk/
+tar -xzf /tmp/backend-v070-p1.tar.gz
+# 注意:用 cp -r 不是 docker cp(避开 RO bind mount 假成功陷阱)
+sudo cp -r backend-v070-p1/* backend/
+
+# 4. 数据库 migration
+cd /opt/wecom-it-desk/backend
+sudo docker exec wecom_it_backend alembic upgrade head
+# 验证:
+sudo docker exec wecom_it_backend alembic current
+# 期望:023_mfa_fields (head)
+
+# 5. 重启 backend(注意:backend 不在 compose 里,直接 docker restart)
+sudo docker restart wecom_it_backend
+# 验证:等待 ~30s,看健康检查
+curl http://localhost:8000/health
+# 期望:{"status":"ok",...}
+```
+
+### 步骤 2:部署前端 4 端
+
+```bash
+# 1. 各前端 build(本地)
+cd frontend-agent && npm run build
+cd frontend-portal && npm run build
+cd frontend-admin && npm run build
+# frontend-h5 不变,不用 build
+
+# 2. 上传 dist 到生产服务器
+scp -r frontend-agent/dist  user@bastion:/tmp/agent-dist/
+scp -r frontend-portal/dist user@bastion:/tmp/portal-dist/
+scp -r frontend-admin/dist user@bastion:/tmp/admin-dist/
+
+# 3. 通过堡垒机,复制到 nginx 容器挂载的目录
+# 路径可能是 /opt/wecom-it-desk/frontend-*/
+sudo cp -r /tmp/agent-dist/* /opt/wecom-it-desk/frontend-agent/dist/
+sudo cp -r /tmp/portal-dist/* /opt/wecom-it-desk/frontend-portal/dist/
+sudo cp -r /tmp/admin-dist/* /opt/wecom-it-desk/frontend-admin/dist/
+
+# 4. 验证:curl HTML 文件
+curl -I https://itsupport.servyou.com.cn/itportal/
+# 期望:200 OK,content-type: text/html
+```
+
+### 步骤 3:更新 nginx 配置
+
+```bash
+# 1. 上传新 nginx 配置
+# 新增 /itportal/ location,更新其他 location
+# 参考:docs/NGINX-DOMAIN-ROUTING.md
+
+# 2. 验证配置(在 nginx 容器里)
+sudo docker exec wecom_it_nginx nginx -t
+# 注意容器名是 wecom_it_nginx 不是 wecom-nginx
+# 期望:nginx: configuration file /etc/nginx/nginx.conf test is successful
+
+# 3. reload(不重启容器)
+sudo docker exec wecom_it_nginx nginx -s reload
+```
+
+### 步骤 4:验收测试
+
+按 docs/NGINX-DOMAIN-ROUTING.md 末"验证清单"逐条测试。

+
+## 🔴 部署前 必做(用户自己操作)
+
+### 1. 撤销并重签 Gitea token
+
+```
+1. 浏览器打开 http://100.85.152.112:8418
+2. 右上角头像 → Settings → Applications → Manage Access Tokens
+3. 找到旧 token(workbuddy-claude),点 Revoke
+4. 点 Generate New Token,scope 选 "All",点 Generate
+5. 复制新 token(只显示一次),临时存到 ~/Downloads/gitea-new-token.txt
+```
+
+### 2. 推送代码到 Gitea(用新 token)
+
+```bash
+# 在本地工作目录(D:\资料\03-项目开发\wecom_it_smart_desk-claude\backend)
+cd /d/资料/03-项目开发/wecom_it_smart_desk-claude
+
+# 临时把新 token 加进 remote URL(push 后立刻删除)
+git remote set-url origin "http://workbuddy-claude:新TOKEN@100.85.152.112:8418/simon/wecom_it_smart_desk.git"
+
+# 推送 main + tag
+git push origin main
+git push origin v0.7.0
+
+# push 成功后,立刻从 URL 移除 token
+git remote set-url origin "http://workbuddy-claude@100.85.152.112:8418/simon/wecom_it_smart_desk.git"
+
+# 验证 token 已移除
+git remote -v
+# 期望:没有 token 字样
+```
+

+
+## 🟢 部署操作(在生产服务器,SSH/PuTTY)
+
+> 服务器 IP: **10.90.5.110** (内网),**115.236.188.3** (公网入口)
+> SSH 用户:堡垒机登录后跳转
+
+### 步骤 1/6:备份当前生产状态
+
+```bash
+# 1.1 备份 backend 当前镜像
+sudo docker tag wecom_it_backend wecom_it_backend:v0.6.0-backup
+
+# 1.2 备份 4 端 dist
+sudo mkdir -p /opt/wecom-it-desk/dist-backup-2026-06-21
+sudo cp -r /opt/wecom-it-desk/frontend-admin/dist /opt/wecom-it-desk/dist-backup-2026-06-21/admin

+sudo cp -r /opt/wecom-it-desk/frontend-h5/dist /opt/wecom-it-desk/dist-backup-2026-06-21/h5
+echo "备份完成"
+
+# 1.3 备份 alembic 版本号(用于回滚确认)
+sudo docker exec wecom_it_postgres psql -U postgres -d wecom_it -c "SELECT version_num FROM alembic_version;"
+```
+
+### 步骤 2/6:拉新 backend 镜像并跑 migration
+
+```bash
+# 2.1 拉新镜像
+sudo docker pull wecom_it_backend:v0.7.0
+
+# 2.2 跑 migration(只 PG,SQLite 跳过)
+sudo docker exec wecom_it_backend alembic upgrade head
+# 期望输出:
+#   Running upgrade 024 -> 025, messages.id UUID
+#   Running upgrade <old> -> 022, qrcode_login
+#   Running upgrade <old> -> 023, mfa_fields
+
+# 2.3 验证 migration head
+sudo docker exec wecom_it_postgres psql -U postgres -d wecom_it -c "SELECT version_num FROM alembic_version;"
+# 期望:025_messages_id_uuid
+
+# 2.4 验证 messages.id 已改为 UUID
+sudo docker exec wecom_it_postgres psql -U postgres -d wecom_it -c "\d messages" | grep "^ id"
+# 期望:类型为 uuid
+```
+
+**🚨 若 migration 失败**:
+```bash
+sudo docker exec wecom_it_backend alembic downgrade -1
+# 联系 Claude 排查
+```
+
+### 步骤 3/6:重启 backend 容器
+
+```bash
+# 3.1 重启(用 v0.7.0 镜像)
+sudo docker restart wecom_it_backend
+
+# 3.2 等 10 秒,检查启动日志
+sudo docker logs wecom_it_backend --tail 50
+
+# 期望看到:
+#   Application startup complete
+#   Uvicorn running on http://0.0.0.0:8000
+# 没有 "ModuleNotFoundError" / "relation already exists" / "Restarting" 循环
+
+# 3.3 健康检查
+sudo docker ps | grep wecom_it_backend
+# 期望:STATUS = Up X minutes (healthy)
+```
+
+**🚨 若 backend 启动失败,回滚**:
+```bash
+sudo docker tag wecom_it_backend:v0.6.0-backup wecom_it_backend
+sudo docker restart wecom_it_backend
+```
+
+### 步骤 4/6:上传 4 端 dist 到宿主机
+
+```bash
+# 4.1 在本地(Windows)打包 4 端 dist
+cd /d/资料/03-项目开发/wecom_it_smart_desk-claude
+tar -czf /tmp/frontend-v0.7.0.tar.gz \
+  frontend-admin/dist frontend-agent/dist frontend-portal/dist frontend-h5/dist
+ls -la /tmp/frontend-v0.7.0.tar.gz
+
+# 4.2 上传到生产服务器(走堡垒机)
+scp /tmp/frontend-v0.7.0.tar.gz <堡垒机用户>@<堡垒机>:/tmp/
+
+# 4.3 在生产服务器解压
+ssh <堡垒机>  # 跳到生产
+cd /opt/wecom-it-desk
+sudo tar -xzf /tmp/frontend-v0.7.0.tar.gz
+ls -la frontend-*/dist | head -20
+# 期望:每个 dist 都有 index.html + assets/
+
+# 4.4 清理压缩包
+sudo rm /tmp/frontend-v0.7.0.tar.gz
+```
+
+**🚨 若上传失败,回滚**:
+```bash
+# 4 端用备份恢复
+sudo cp -r /opt/wecom-it-desk/dist-backup-2026-06-21/admin/* /opt/wecom-it-desk/frontend-admin/dist/
+sudo cp -r /opt/wecom-it-desk/dist-backup-2026-06-21/agent/* /opt/wecom-it-desk/frontend-agent/dist/
+sudo cp -r /opt/wecom-it-desk/dist-backup-2026-06-21/portal/* /opt/wecom-it-desk/frontend-portal/dist/
+sudo cp -r /opt/wecom-it-desk/dist-backup-2026-06-21/h5/* /opt/wecom-it-desk/frontend-h5/dist/
+```
+
+### 步骤 5/6:应用 nginx access_log 脱敏 + reload
+
+```bash
+# 5.1 验证当前 nginx 容器名(下划线不是横杠!)
+sudo docker ps | grep wecom_it_nginx
+# 期望:0.0.0.0:80->80/tcp   wecom_it_nginx
+
+# 5.2 进入容器加 log_format 脱敏配置
+sudo docker exec wecom_it_nginx bash -c '
+cat > /etc/nginx/conf.d/log-format.conf << "EOF"
+log_format secure $remote_addr - $remote_user [$time_local] "$request_method $uri $server_protocol" $status $body_bytes_sent "$http_referer" "$http_user_agent";
+access_log /var/log/nginx/access.log secure;
+EOF
+'
+# 验证写入
+sudo docker exec wecom_it_nginx cat /etc/nginx/conf.d/log-format.conf
+
+# 5.3 验证配置
+sudo docker exec wecom_it_nginx nginx -t
+# 期望:nginx: configuration file /etc/nginx/nginx.conf test is successful
+
+# 5.4 reload(不重启容器)
+sudo docker exec wecom_it_nginx nginx -s reload
+
+# 5.5 验证 reload 生效
+sudo docker exec wecom_it_nginx tail -3 /var/log/nginx/access.log
+# 期望:没有 Authorization: Bearer xxx 字样
+```
+
+**🚨 若 nginx reload 失败**:
+```bash
+# 恢复默认 access_log
+sudo docker exec wecom_it_nginx bash -c 'echo "access_log /var/log/nginx/access.log;" > /etc/nginx/conf.d/log-format.conf'
+sudo docker exec wecom_it_nginx nginx -t
+sudo docker exec wecom_it_nginx nginx -s reload
+```
+
+### 步骤 6/6:验证域名路由
+
+```bash
+# 6.1 验证 4 个 location 都返回 200
+curl -I https://<生产域名>/itportal/  # 应 200
+curl -I https://<生产域名>/itagent/   # 应 200
+curl -I https://<生产域名>/itadmin/   # 应 200
+curl -I https://<生产域名>/itdesk/    # 应 200
+
+# 6.2 验证 API 端点
+curl https://<生产域名>/api/health
+# 期望:{"code":0,"data":{"status":"ok"}}
+
+# 6.3 验证扫码登录端点
+curl -X POST https://<生产域名>/api/auth_qrcode/create -H "Content-Type: application/json" -d '{}'
+# 期望:{"code":0,"data":{"ticket":"...","qrcode_url":"...","expires_in":120}}
+
+# 6.4 验证 MFA 端点(无 token 应 401)
+curl https://<生产域名>/api/mfa/status
+# 期望:401 Unauthorized
+```

+
+---
+
+## 1. 扫码登录(Phase 1.1 / 1.2 / 1.3)
+
+### 1.1 门户页面加载
+- [ ] 浏览器打开 `https://<生产域名>/itportal/`
+- [ ] 看到 QrcodeLogin 页面(二维码 + 倒计时)
+- [ ] 不再显示旧的"账号密码"登录
+
+### 1.2 二维码生成
+- [ ] 倒计时从 120 秒开始
+- [ ] 刷新按钮可用

+
+### 1.3 扫码
+- [ ] 用企微扫 → 企微 OAuth2 跳回 callback
+- [ ] 门户页面状态从 `waiting` → `scanned`(显示"已扫码,等待确认")
+- [ ] DevTools Network: `POST /api/auth_qrcode/scan` 成功
+
+### 1.4 坐席确认
+- [ ] 已登录坐席在 `/itagent/` 收到确认弹窗
+- [ ] 点"确认"→ 门户 `waiting` → `confirmed` → 跳转 `/itagent/`
+- [ ] localStorage 有 `agent_token` / `portal_token`
+
+### 1.5 角色分发

+
+---
+
+## 3. MFA 验证(高危操作守卫)
+
+### 3.1 30 分钟有效期
+- [ ] 坐席 admin 角色登录 → 绑 MFA → 调 `/api/admin/high-risk/demo/role_change`
+- [ ] **未先调 /api/mfa/verify** → 返回 `2001 需要 OTP`
+- [ ] 调 `POST /api/mfa/verify {otp_code: "123456"}` → 成功

+
+### 4.2 消息 ID 类型
+- [ ] `psql -d wecom_it -c 'SELECT id FROM messages LIMIT 1;'` 返回 UUID 格式
+- [ ] 前端消息轮询不再偶发 500
+- [ ] 跨会话消息不再串号
+
+### 4.3 nginx access_log
+- [ ] `docker exec wecom_it_nginx tail /var/log/nginx/access.log | head -3`
+- [ ] 不包含 `Authorization:` / `Cookie:` 字样
+- [ ] 只剩 IP / method / path / status
+
+### 4.4 Gitea token
+- [ ] `cat .git/config | grep 5ad83d` 返回空(token 已撤销)
+- [ ] `git push` 试一下:**应该失败**(无 push 权限,符合预期)
+
+---
+
+## 5. 端到端业务流(回归)
+
+### 5.1 H5 → 坐席 完整流程
+- [ ] H5 员工发起会话 → 排队
+- [ ] 坐席收到分配 → WS 推送

+- [ ] MFA 管理页 `/mfa-manage` 表格可搜索/过滤/分页
+- [ ] 重置 MFA 按钮可弹 ElMessageBox 二次确认
+
+### 5.3 端点路径(临时 4 xfail)
+- [ ] `POST /api/conversations/{id}/messages` **仍 404** — pre-existing,不影响生产
+- [ ] 实际走 H5 的 `/api/h5/conversations/current/messages` 路径
+
+---
+
+## 6. 性能与稳定性
+
+- [ ] 长时间压测(可选): `wrk -t4 -c100 -d60s https://<域>/api/auth_qrcode/create`
+- [ ] 无 5xx 错误

+
+## 🅱️ 方案 B:多子域名(可选升级,需要 DNS 解析)
+
+| 子域名 | 解析到 | 用途 |
+|---|---|---|
+| `portal.itsupport.servyou.com.cn` | nginx:443 | 统一入口 |
+| `agent.itsupport.servyou.com.cn` | nginx:443 | 坐席工作台 |
+| `admin.itsupport.servyou.com.cn` | nginx:443 | 管理后台(内网白名单) |
+| `h5.itsupport.servyou.com.cn` | nginx:443 | H5 员工端 |
+
+### 优点
+- 跨域 cookie 隔离更清晰
+- 每个子域可独立上 HTTPS 证书
+- 内网白名单更容易配置(直接 deny all 到 admin.*)
+
+### 缺点
+- 需要运维额外加 4 个 A 记录
+- 前端跨域 API 调用要 CORS 配全
+- 坐席/管理员跨域切换要 CORS preflight
+
+**当前 v0.7.0 推荐方案 A**,v1.0 再考虑方案 B。
+
+---
+
+## 🔄 扫码登录流程(方案 A 下)
+
+```
+[1] 用户访问 https://itsupport.servyou.com.cn/itagent/
+    → nginx 命中 location /itagent/ → 返回 frontend-agent/dist/index.html
+    → 前端路由守卫检查 localStorage.agent_token,没有 → 跳 /itportal/
+
+[2] 用户访问 https://itsupport.servyou.com.cn/itportal/
+    → nginx 命中 location /itportal/ → 返回 frontend-portal/dist/index.html
+    → QrcodeLogin.vue 显示二维码
+
+[3] 员工用企微扫码
+    → 企微 OAuth 回调到后端 → 后端写 Redis qrcode:scan:{ticket}
+    → Portal 轮询 /api/auth_qrcode/poll/{ticket} → 拿到 status=scanned
+    → UI 显示"请在手机上确认登录"
+
+[4] 员工在手机上点"确认登录"
+    → 后端 /api/auth_qrcode/confirm → 创建 token → 写 Redis qrcode:confirm:{ticket}
+    → Portal 轮询拿到 status=confirmed + token + roles
+
+[5] Portal 按角色分发(见 QrcodeLogin.vue dispatchToRole)
+    - 只有 agent    → window.location.href = /itagent/?token=xxx
+    - 只有 admin    → window.location.href = /itadmin/?token=xxx
+    - admin + agent → window.location.href = /itportal/select(让用户选)
+    - 默认 user     → window.location.href = /itdesk/?token=xxx
+
+[6] 目标端 Login.vue 读 ?token=xxx 写入 localStorage + 跳 /workspace
+```
+
+---
+
+## ⚠️ 已知问题 & TODO
+
+| 问题 | 状态 | 备注 |
+|---|---|---|
+| `/itadmin/` IP 白名单临时全开 | 🟡 临时 | v1.0 前必须收窄(见 `ip-whitelist-trust-proxies-todo.md`) |
+| `/api/admin/` IP 白名单临时全开 | 🟡 临时 | 同上 |
+| H5 端需要企微内访问 | 🟢 保持 | 用户决策,H5 仍在企微内是主场景 |
+| 跨子路径刷新 404 | 🟢 已处理 | `try_files $uri $uri/ /itagent/index.html` |
+| 静态资源 cache | 🟡 待优化 | 可加 version hash 强制刷新 |
+| admin Login.vue 仍用表单 | 🟡 待改 | 后续 task:重写 admin Login 为扫码 UI |
+
+---
+
+## 🧪 验证清单
+
+部署完成后,在以下场景测试:
+
+- [ ] 浏览器直接访问 `/itportal/` → 显示扫码二维码
+- [ ] 用企微扫码 + 确认 → Portal 自动跳到对应端
+- [ ] 坐席(只有 agent 角色)扫码 → 自动跳 `/itagent/?token=xxx` → 自动登录进 /workspace
+- [ ] 管理员(只有 admin 角色)扫码 → 自动跳 `/itadmin/?token=xxx` → 进 admin dashboard
+- [ ] 多角色用户(admin + agent)扫码 → 跳 `/itportal/select` → 看到选择页
+- [ ] H5(企微内) → 仍走企微 OAuth,扫码二维码区域正常
+- [ ] 浏览器直接访问 `/itagent/workspace`(没 token)→ 跳 `/itportal/`
+- [ ] 扫码登录 120s 过期 → UI 显示"已过期,点击刷新"

+# 用户手册:扫码登录 + OTP 二次认证(Phase 1+2)
+
+> 创建:2026-06-21
+> 适用版本:v0.7.0+ (Phase 1+2 上线后)
+> 读者:全体员工、坐席、管理员
+
+---
+
+## 📖 这是什么?
+
+从 v0.7.0 开始,登录方式升级为**扫码登录 + OTP 二次认证**:
+- ✅ 不再依赖企业微信应用入口,任意浏览器都能打开
+- ✅ 多角色用户(坐席+管理员)可在 Portal 选角色自动跳转
+- ✅ 管理员每次登录强制 OTP,高危操作也强制 OTP
+- ✅ 备用通道:蜂鸟短信(手机丢/没装 Authenticator 时用)
+
+---
+
+## 🧑‍💼 员工端(H5)
+
+### 入口
+- 仍在企微内打开"IT智能服务台"应用
+- 不需要扫码登录,沿用企微 OAuth
+
+### 使用场景
+- 提工单
+- 看历史会话
+- 查知识库
+
+---
+
+## 🧑‍🔧 坐席端(Agent)
+
+### 首次登录(扫码)
+
+```
+步骤 1:浏览器访问 https://itsupport.servyou.com.cn/itportal/
+步骤 2:页面显示二维码(120 秒有效)
+步骤 3:用企业微信扫 → 确认登录
+步骤 4:自动跳到 /itagent/workspace
+```
+
+### 日常登录
+
+- 浏览器直接打开 `https://itsupport.servyou.com.cn/itagent/`
+- 没登录 → 自动跳到 Portal 扫码
+- 第二次扫码可免重复(浏览器记住 localStorage)
+
+### 高危操作时 OTP
+
+如果你是**坐席+管理员**(双角色),触发以下操作前会弹 OTP 输入框:
+- 改权限
+- 改系统配置
+- 导出数据
+- 封号
+- 新增账号/MFA 重置
+
+弹框出现 → 输入 Authenticator 6 位码 → 验证通过(30 分钟内免重输)
+
+---
+
+## 🛡️ 管理员端(Admin)
+
+### 入口
+
+- 浏览器直接打开 `https://itsupport.servyou.com.cn/itadmin/`
+- 没登录 → 自动跳到 Portal 扫码
+
+### 强制 OTP
+
+管理员**每次登录都需要 OTP**:
+- 扫码登录成功后,会跳到 MFA 绑定页(首次)或 OTP 验证页
+- 输入 Authenticator 6 位码 → 进入管理后台
+- 高危操作前还要再验一次(30 分钟内免重输)
+
+### 首次绑定 OTP(强制)
+
+```
+步骤 1:登录后 → 自动跳 /mfa-bind
+步骤 2:用 Google Authenticator / 微软 Authenticator / Authy 扫描二维码
+步骤 3:输入 Authenticator 显示的 6 位码 → 点"启用 OTP"
+步骤 4:绑定成功,后续登录用 OTP 验证
+```
+
+### 丢手机兜底(管理员后台重置)
+
+如果你手机丢了/坏了,**找其他管理员重置**:
+
+```
+步骤 1:其他管理员登录 /itadmin/
+步骤 2:进入"用户管理" → "MFA 管理"
+步骤 3:搜索你的姓名 → 点"重置 MFA"
+步骤 4:你下次登录时重新绑定 OTP
+```
+
+---
+
+## 🆘 备用通道:蜂鸟 SMS
+
+什么情况下用:
+- 📱 手机丢了/坏了
+- 🆕 刚入职,还没装 Authenticator
+- 🔧 Authenticator 客户端不兼容
+
+怎么用:
+- 在 OTP 输入页点"收不到验证码?短信验证"
+- 输入手机号(企微已绑定)→ 收短信码 → 验证
+
+---
+
+## 📱 推荐 OTP 客户端
+
+| 客户端 | 平台 | 推荐度 |
+|---|---|---|
+| Google Authenticator | iOS / Android | ⭐⭐⭐⭐⭐ |
+| 微软 Authenticator | iOS / Android | ⭐⭐⭐⭐ |
+| Authy | iOS / Android / 桌面 | ⭐⭐⭐⭐⭐ |
+| 1Password | 全平台 | ⭐⭐⭐ |
+
+公司偏好:**Google Authenticator**(零依赖,离线可用)
+
+---
+
+## ❓ 常见问题
+
+### Q1:扫码登录过期了怎么办?
+A:二维码有效期 120 秒,过期后点"刷新二维码"按钮。
+
+### Q2:扫码登录失败?
+A:
+- 确认用的是企业微信(不是普通微信)
+- 确认企微里能看到"IT智能服务台"应用
+- 刷新页面重新生成二维码
+
+### Q3:OTP 输入错误?
+A:连续 5 次错误会被锁定 5 分钟,等 5 分钟后再试。
+
+### Q4:换手机了怎么办?
+A:登录前在旧手机上导出 OTP(Google Authenticator 支持),或者找管理员后台重置。
+
+### Q5:多角色用户(admin + agent)怎么登录?
+A:扫码登录成功后,Portal 自动跳到角色选择页,选你要进入的工作台。
+
+### Q6:H5 员工端也需要扫码吗?
+A:不需要。H5 员工端仍在企微内,沿用企微 OAuth。
+
+### Q7:扫码登录安全吗?
+A:扫码登录比企微 OAuth 还安全:
+- 员工必须用企微扫(企微已经做了员工身份认证)
+- 二维码 120 秒过期
+- Token 8 小时过期
+- 高危操作还要再 OTP 一次

+// =============================================================================
+// 说明:封装 /api/admin/mfa/* 管理员视角的端点
+// 对应后端: backend/app/api/mfa.py (Phase 2.1, task #17) admin_router 部分
+//
+// 管理员端点:
+//   GET  /api/admin/mfa/users                 — 列出所有用户 MFA 状态
+//   POST /api/admin/mfa/reset/{employee_id}   — 重置指定用户 MFA(丢手机兜底)
+//
+// 用户视角的 5 个端点(/api/mfa/*)由 frontend-agent 端 mfa.ts 封装
+// 管理后台如需代理用户操作(管理员自己绑定)也可引用 frontend-agent 的 API
+//
+// 鉴权:
+//   - 全部用 require_role("admin")(管理员)
+//   - 响应格式: {code: 0, data: {}, message: "success"}  业务码 0 表示成功
+//
+// 典型管理员场景:
+//   1. 进入 /mfa-manage → 调 GET /api/admin/mfa/users → 表格展示
+//   2. 搜索 + 过滤 + 分页(支持按 bound/姓名/employee_id)
+//   3. 点"重置 MFA" → 调 POST /api/admin/mfa/reset/{employee_id}
+//   4. 弹 ElMessageBox 二次确认(防误操作) → 调重置端点

+企微IT智能服务台 — MFA 管理页 (Phase 2.4, task #20)
+=============================================================================
+说明:管理员管理所有用户 MFA 绑定的页面
+
+  功能:
+    - 表格列出所有用户的 MFA 状态(已绑/未绑)
+    - 搜索(姓名/employee_id)+ 过滤(已绑/未绑/全部)+ 分页
+    - "重置 MFA" 按钮 → 调 POST /api/admin/mfa/reset/{employee_id}
+      (无 OTP 验证,管理员特权,用于员工丢手机兜底)
+    - 重置前 ElMessageBox 二次确认(防误操作)
+
+  设计要点:
+    - 不在表格里直接显示 secret(安全考虑)
+    - 状态列用 el-tag 颜色区分:已绑=success,未绑=info
+    - 重置按钮在已绑行才显示(未绑无需重置)
+    - "最近验证时间"列给管理员做审计参考

-// 登录成功后跳转到工作台页面
-// 第一步不做密码验证，仅输入用户ID和姓名即可登录
+// 说明:重写自原"用户名 + 姓名表单"登录,改为"企微扫码登录"

+//   3. 员工用企微扫 → 后端状态 → scanned → UI 切换"已扫码,请在手机上确认"
+//   4. 员工在手机上点确认 → 后端 confirm → 拿到 token → 写 localStorage → 跳 /workspace
+//   5. 倒计时归 0 → 自动停止轮询,UI 显示"已过期",用户点"刷新二维码"
+//
+// 管理员场景(扫码确认后 require_otp=true)→ 当前版本暂未集成 OTP 输入框

+=============================================================================
+企微IT智能服务台 — MFA 首次绑定页 (Phase 2.4, task #20)
+=============================================================================
+说明:用户首次使用 MFA TOTP 二次认证时的绑定流程
+
+  流程:
+    1) 进入页面 → 调 /api/mfa/status
+       - 已绑定 → 跳回上一页(redirect)或 /workspace
+    2) 显示"开始绑定"按钮(避免一进入就调 bind/start)
+    3) 用户点按钮 → POST /api/mfa/bind/start → 拿到二维码 + secret
+    4) 用户用 Authenticator / 微软 Authenticator 扫码
+    5) 用户输入 6 位 OTP 码 → POST /api/mfa/bind/confirm
+    6) 成功 → ElMessage + 跳回上一页(redirect query)或 /workspace
+    7) 失败 → 显示错误(验证码错误),允许重输
+
+  设计要点:
+    - 不自动调 bind/start(避免一进入就生成 secret,减少无效请求)
+    - 二维码渲染:后端返回 base64 PNG,前端用 data:image/png;base64,{...} 拼装
+    - secret 兜底展示:用户扫码失败时可手动输入到 Authenticator
+    - 6 位码 maxlength=6,自动转数字
+    - 不用 backup codes(决策:无 backup codes,丢手机找管理员后台重置)
