+- 新媒体路径只在状态为运行正常或等待首次探测、且仍有配置容量的分片中确定性分配；同一路径重复处理必须保持原归属。
+- 分片异常、停用或状态陈旧都不得自动改写已有路径归属。详情必须能定位受影响的设备、位置、Profile 和媒体路径，同时不返回 Control API、RTSP URI 或凭据。
+- 跨分片迁移预检是只读操作，只检查源状态、全部受影响路径和候选目标容量；即使预检通过也不授予执行权限。实际迁移必须另建高风险工单并取得人工确认。
+- 额外分片只能配置为 external，Control API 必须使用无用户信息、无查询参数、无路径的本机回环 HTTP 地址。Sense 不停止外部实例。

+主 MediaMTX 继续使用 `SENSE_MEDIAMTX_MODE`、`SENSE_MEDIAMTX_BINARY`、`SENSE_MEDIAMTX_CONFIG` 和 `SENSE_MEDIAMTX_API`。可选 `SENSE_MEDIAMTX_CAPACITY` 为正整数；留空时使用数据库中的当前统一配额。
+
+额外分片通过 `SENSE_MEDIAMTX_SHARDS_FILE` 指向仓库外 JSON 文件。相对路径按 Windows 交付包根目录解析；示例结构见包内 `config\mediamtx-shards.example.json`。每项必须包含唯一 id、名称、本机回环 Control API 和正容量，mode 只能为 external。文件不得包含摄像头账号、密码、数据库连接或其他秘密。
+
+额外 MediaMTX 进程由部署方独立启动并为各实例分配不冲突的 API、RTSP 及其他监听端口；Sense 只做健康探测和路径管理，不启停这些外部进程。升级后看不到“媒体分片”时，确认迁移 `2026082814000_media_shard.go` 成功并重新登录刷新动态菜单。
+
+页面“运行异常”表示最近一次 Control API 探测失败；“状态已陈旧”表示运行循环已超过 30 秒没有更新探测结果。故障时先在详情定位设备/Profile/路径，不要手工改数据库归属。迁移预检不会执行迁移；任何实际跨分片迁移都必须另建高风险工单和回退方案。
