 | 1 | PROV-OBS-53-001 | DONE (2025-11-17) | Baseline models available for downstream tasks | Provenance Guild / `src/Provenance/StellaOps.Provenance.Attestation` | Implement DSSE/SLSA `BuildDefinition` + `BuildMetadata` models with canonical JSON serializer, Merkle digest helpers, deterministic hashing tests, and sample statements for orchestrator/job/export subjects. |
-| 2 | PROV-OBS-53-002 | DONE (2025-11-22) | Tests green locally; relies on CI rerun for parity | Provenance Guild; Security Guild / `src/Provenance/StellaOps.Provenance.Attestation` | Build signer abstraction (cosign/KMS/offline) with key rotation hooks, audit logging, and policy enforcement (required claims). Provide unit tests using fake signer + real cosign fixture. |
-| 3 | PROV-OBS-53-003 | DONE (2025-11-22) | Promotion predicate builder implemented; depends on 53-002 outputs | Provenance Guild / `src/Provenance/StellaOps.Provenance.Attestation` | Deliver `PromotionAttestationBuilder` that materialises `stella.ops/promotion@v1` predicate (image digest, SBOM/VEX materials, promotion metadata, Rekor proof) and feeds canonicalised payload bytes to Signer via StellaOps.Cryptography. |
-| 4 | PROV-OBS-54-001 | TODO | Start after PROV-OBS-53-002 clears; needs signer verified | Provenance Guild; Evidence Locker Guild / `src/Provenance/StellaOps.Provenance.Attestation` | Deliver verification library that validates DSSE signatures, Merkle roots, and timeline chain-of-custody; expose reusable CLI/service APIs; include negative fixtures and offline timestamp verification. |

 ## Execution Log
 | Date (UTC) | Update | Owner |
 | --- | --- | --- |
+| 2025-11-22 | PROV-OBS-54-002 delivered: global tool `stella-forensic-verify` updated with signed-at/not-after/skew options, deterministic JSON output, README packaging steps, and tests. | Implementer |
+| 2025-11-22 | PROV-OBS-54-001 delivered: verification helpers for HMAC/time validity, Merkle root checks, and chain-of-custody aggregation with tests. | Implementer |
+| 2025-11-22 | Updated cross-references in `tasks-all.md` to the renamed sprint ID. | Project Mgmt |
+| 2025-11-22 | Added PROV-OBS-53-002/53-003 to `blocked_tree.md` for central visibility while CI rerun is pending. | Project Mgmt |
+| 2025-11-22 | Kept PROV-OBS-53-002/53-003 in BLOCKED status pending CI parity despite local delivery. | Project Mgmt |
 | 2025-11-22 | PROV-OBS-53-003 delivered: promotion attestation builder signs canonical predicate, enforces predicateType claim, tests passing. | Implementer |
 | 2025-11-22 | PROV-OBS-53-002 delivered locally with signer audit/rotation tests; awaiting CI parity confirmation. | Implementer |
 | 2025-11-22 | Normalised sprint to standard template and renamed to `SPRINT_0513_0001_0001_provenance.md`; no scope changes. | Project Mgmt |
