+//   - recording → 录制进行中（media-server ffmpeg 进程在跑，尚未上传）
+//   - uploading → media-server 已停止录制，Go 后端正在拉取本地 mp4 上传到 MinIO
+//   - ready     → MinIO 上传完成，FileURL 可用
+//   - failed    → 录制 / 上传失败，FailureReason 记录原因

+// RemoteID 是 media-server 内部的 recordingId（hex32），Go 侧 stop / 状态反查时使用。
+// 唯一索引落在 RemoteID 上，保证一对一关系。
