- 新增国家级/用户级 Redis 写锁（token+Lua 安全释放），统一 country -> user 锁序 - 后台改国家码/名称时按 countryId 游标分批同步 RDS 与 mongo 全部国家冗余字段， 含注册国家码同事务重命名、团队区域重算（CAS + 投影回滚）与两次缓存失效 - 建团（BD 邀请/后台）、改用户资料、注册、编辑团队等写国家快照路径接入锁防竞态， 团队国家码一律取国家主表标准值 - 违规调整/账号状态改为仅写变更字段，防止旧快照覆盖同步结果 - 团队账单结算改用账单自身 region，配合团队迁区 - 补充 user_base_info (country_id,id) 索引与 mongo 复合索引迁移脚本 Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

-- 生产表当前约 1.4 万行/4.5 MB，使用 INPLACE + LOCK=NONE，且限制元数据锁等待避免影响在线请求。
