Task ID | State | Task description | Owners (Source)
--- | --- | --- | ---
> 2025-11-05: Resumed instrumentation work to match `policy_simulation_latency_seconds` naming, add coverage for SSE latency recording, and validate webhook sample alignment before closing.
> 2025-11-05: Ship telemetry updates + tests; local `dotnet test` blocked by pre-existing GraphJobs accessibility errors (`IGraphJobStore.UpdateAsync`).
> 2025-11-06: Added tenant-aware tagging to `policy_simulation_queue_depth` gauge samples and extended metrics-provider unit coverage.

> 2025-11-07: Worker counterpart (SCHED-WORKER-20-301) now DOING; revisit once API scaffolding lands.
> 2025-11-04: Graph job completions now persist to Mongo with optimistic guards, emit Redis/webhook notifications once per transition, and refresh result URI metadata idempotently (tests cover service + Mongo store paths).
