[Notifications & Telemetry] 170.B) Telemetry Depends on: Sprint 150.A - Orchestrator Summary: Notifications & Telemetry focus on Telemetry).

Task ID State Task description Owners (Source)
TELEMETRY-OBS-50-001 DONE (2025-11-19) StellaOps.Telemetry.Core bootstrap library shipped with structured logging facade, OTEL configuration helpers, deterministic bootstrap (service name/version detection, resource attributes), and sample usage for web/worker hosts. Evidence: docs/observability/telemetry-bootstrap.md. Telemetry Core Guild (src/Telemetry/StellaOps.Telemetry.Core)
TELEMETRY-OBS-50-002 TODO Implement context propagation middleware/adapters for HTTP, gRPC, background jobs, and CLI invocations, carrying trace_id, tenant_id, actor, and imposed-rule metadata. Provide test harness covering async resume scenarios. Dependencies: TELEMETRY-OBS-50-001. Telemetry Core Guild (src/Telemetry/StellaOps.Telemetry.Core)
TELEMETRY-OBS-51-001 TODO Ship metrics helpers for golden signals (histograms, counters, gauges) with exemplar support and cardinality guards. Provide Roslyn analyzer preventing unsanitised labels. Dependencies: TELEMETRY-OBS-50-002. Telemetry Core Guild, Observability Guild (src/Telemetry/StellaOps.Telemetry.Core)
TELEMETRY-OBS-51-002 TODO Implement redaction/scrubbing filters for secrets/PII enforced at logger sink, configurable per-tenant with TTL, including audit of overrides. Add determinism tests verifying stable field order and timestamp normalization. Dependencies: TELEMETRY-OBS-51-001. Telemetry Core Guild, Security Guild (src/Telemetry/StellaOps.Telemetry.Core)
TELEMETRY-OBS-55-001 TODO Provide incident mode toggle API that adjusts sampling, enables extended retention tags, and records activation trail for services. Ensure toggle honored by all hosting templates and integrates with Config/FeatureFlag providers. Dependencies: TELEMETRY-OBS-51-002. Telemetry Core Guild (src/Telemetry/StellaOps.Telemetry.Core)
TELEMETRY-OBS-56-001 TODO Add sealed-mode telemetry helpers (drift metrics, seal/unseal spans, offline exporters) and ensure hosts can disable external exporters when sealed. Dependencies: TELEMETRY-OBS-55-001. Telemetry Core Guild (src/Telemetry/StellaOps.Telemetry.Core)

Status notes (2025-11-19 UTC)

  • TELEMETRY-OBS-50-001 – DONE. Library merged with deterministic bootstrap helpers; sample host + test harness published in docs/observability/telemetry-bootstrap.md.
  • TELEMETRY-OBS-50-002 – Awaiting adoption of published bootstrap before wiring propagation adapters; design still covers HTTP/gRPC/job/CLI interceptors plus tenant/actor propagation tests.
  • TELEMETRY-OBS-51-001/51-002 – On hold until propagation middleware stabilizes; Security Guild still reviewing scrub policy (POLICY-SEC-42-003).
  • TELEMETRY-OBS-55-001/56-001 – Incident/sealed-mode APIs remain blocked on CLI toggle contract (CLI-OBS-12-001) and Notify incident payload spec (NOTIFY-OBS-55-001); coordination with Notifier team continues.
