Interface SchedulerDiagnosticsResponse

The scheduler diagnostics response the connector serves for GET /v1/scheduler (M98k).

sources lists every registered scheduler source in registration order under a session-local sourceId (s1…s16). state is unsupported when no source is registered; otherwise ready if any source is ready, then collection-failed, stale, no-data, disabled, unsupported in that priority order, with each individual state still visible in its entry.
