 - 必须设置连接超时、查询超时、慢查询冷却和连接失败熔断；一次失败后进入冷却，已有旧快照时继续提供本地数据，不得连续重试。
 - 上游 API 必须保留 `X-Caiwu-Data-Status` 和 `X-Caiwu-Data-Synced-At` 响应头；验收同时检查数据状态和同步时间，不能只看 HTTP 200。
 - `JIANSUN_ENABLED` 默认关闭；只允许在现有只读访问方式完成受控连通性和单查询探测后，通过服务器私有 `runtime/.env` 开启。
+- 首次启用必须同时设置 `JIANSUN_ALLOWED_SCOPES`，先开放已完成探测的小表范围；不得用 `*` 跳过核心大表的独立验证。
 - 当前方案是近实时查询快照，不得冒充完整行级增量复制。没有可靠变更标记时，禁止定时全表扫描；历史一致性只能采用低频、小批量、可中止的核对。
 - 首次全量历史数据同步必须单独评估行数、时间窗口和上游低峰期，不得在日常发布时自动执行。
 - 上游地址、账号、密码只允许存在于服务器私有环境配置；代码、提交、PR、共享文档和日志中一律不得出现真实值。

 这套策略提供的是近实时查询快照，不等同于复制上游全库。对于没有可靠更新时间或删除标记的旧表，不能声称实现了完整行级增量；禁止为了追求秒级实时而周期性扫描数百万行。页面实时性依靠本地快照和一分钟后台刷新，历史一致性只能通过低频、小批量、可随时停止的核对补齐。
