Oliver Kieselbach 5cb9b0b30b backend: storage SDK budgets under the agent timeout, ingest 503 on an exhausted budget, request-token fan-outs, single-flight factory budget, ProcessStall monitor (audit F09, D-203) ...

- StorageClientOptions: Table/Queue 8 s per attempt × 3 attempts + capped backoffs = 25.8 s < the
  agent's 30 s upload timeout (pinned by test); Blob 60 s × 4. Every production client takes its
  options from there. No Polly over the SDK.
- StorageErrors.IsTransient(Exception): OperationCanceled / IO / HttpRequest / Aggregate-of-those
  / RequestFailed status 0; the ingest answers 503 + Retry-After instead of 500.
- The ingest still takes no caller cancellation (a batch is a unit). GetAllSessionsPageAsync
  carries the request token down to BoundedFanOut (Global Admin list); SingleFlightCache hands its
  factory a 30 s budget token and evicts on timeout (tenant ids, app-summary snapshot, session stats).
- ProcessStallMonitor: 1 s tick drift ≥ 1 s ⇒ ProcessStall event (sampling bypass) + metric with
  cause gc / threadpool / unknown from GC.GetTotalPauseDuration and thread-pool counters;
  GcPauseMs on request rows ≥ 100 ms. Measures the instance-local 5–10 s pauses seen in production.
- Gitlinks: internal (plan, D-203, concept doc, B-9hf, lesson), .claude/commands (marker rows).

ProcessStallMonitor.cs

backend: storage SDK budgets under the agent timeout, ingest 503 on an exhausted budget, request-token fan-outs, single-flight factory budget, ProcessStall monitor (audit F09, D-203)

StorageDependencyFilterProcessor.cs

chore: bump .claude/commands (platform-health skill, backend-logs corrections) and internal (marker-catalog rule) gitlinks; drop stale index dual-write mention in the dependency filter comment

StorageMetrics.cs

backend: keep slow storage successes and count CAS conflicts as a metric (audit F10)
