+Revision ID: 022_qrcode_login
+Revises: 021_rbac
+Create Date: 2026-06-21
+
+Phase 1.1 扫码登录后端接口(task #14)。
+
+设计说明:
+ 扫码登录的所有状态都存在 Redis(无需新增数据库表):
+ - 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

+
+为什么需要独立字段而非复用早期 otp_*:
+ Phase 2.1 的 MFA 是面向全员(员工 + 坐席)的统一二次认证方案,
+ 与早期仅供 admin 强制 OTP 的 otp_secret / otp_enabled 是两套体系。
+ 字段独立便于后续维护 + 迁移路径清晰。
+
+为什么不破坏现有坐席:
+ - mfa_secret 默认为 NULL,允许已注册坐席不绑定
+ - mfa_enabled 用 server_default=text('false')(字符串 false,不是 Python False),

+# 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
