+## Implementation Status
+
+### Delivery Phases
+- **Phase 1 – Observability baselines:** Instrument writer/projector with metrics, structured logs, OTLP exporters, Grafana dashboards + alert rules
+- **Phase 2 – Determinism harness:** Finalize NDJSON fixtures for ≥5M findings/tenant, implement replay harness CLI, add CI pipeline jobs
+- **Phase 3 – Deployment & backup collateral:** Integrate ledger service into Compose/Helm, automate PostgreSQL migrations, document backup cadence
+- **Phase 4 – Provenance & air-gap extensions:** Ingest orchestrator run export metadata, extend ledger events for bundle provenance, store attestation pointers
+
+### Key Dependencies
+- AdvisoryAI Sprint 110.A completion (raw findings parity)
+- Observability schema approval to unblock Phase 1 instrumentation
+- QA lab capacity for 5M replay checkpoint
+- DevOps review of Compose/Helm overlays
+- Orchestrator export schema freeze for provenance linkage
+
+### Acceptance Criteria
+- Metrics/logging/tracing implementation merged with dashboards exported
+- Harness CLI + fixtures + signed reports committed
+- Compose/Helm overlays + backup/restore runbooks validated
+- Air-gap provenance fields documented + implemented
+- Sprint tracker and release notes updated after each phase
