 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.

 - **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-51-001** – DONE. Golden signal metrics (`GoldenSignalMetrics.cs`) with exemplar support and cardinality guards already existed. Added Roslyn analyzer project (`StellaOps.Telemetry.Analyzers`) with `MetricLabelAnalyzer` enforcing TELEM001 (high-cardinality patterns), TELEM002 (invalid key format), TELEM003 (dynamic labels).
+- **TELEMETRY-OBS-51-002** – DONE. Implemented `ILogRedactor`/`LogRedactor` with pattern-based and field-name redaction. Per-tenant overrides with TTL and audit logging. `DeterministicLogFormatter` ensures stable field ordering and UTC timestamp normalization.
 - **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.
