- Added `FilesystemPackRunProvenanceWriter` to write provenance manifests to the filesystem.
- Introduced `MongoPackRunArtifactReader` to read artifacts from MongoDB.
- Created `MongoPackRunProvenanceWriter` to store provenance manifests in MongoDB.
- Developed unit tests for filesystem and MongoDB provenance writers.
- Established `ITimelineEventStore` and `ITimelineIngestionService` interfaces for timeline event handling.
- Implemented `TimelineIngestionService` to validate and persist timeline events with hashing.

+
+## Wave Coordination
+- Wave 1: TIMELINE-OBS-52 chain (service bootstrap → ingestion → APIs → RLS/policies).
+- Wave 2: Evidence linkage (TIMELINE-OBS-53-001) after digest schema lands and RLS is approved.
+
+## Wave Detail Snapshots
+- Wave 1 deliverable: tenant-scoped timeline service with deterministic ingestion, pagination, and RLS/audit logging ready for Security review.
+- Wave 2 deliverable: evidence linkage endpoint returning signed manifest references tied to EvidenceLocker digests/attestations.
+
+## Interlocks
+| Dependency | Impacts | Status / Next signal |
+| --- | --- | --- |
+| Orchestrator/Notifications event schema | Tasks 2–4 | Pending; required to finalize ingestion payload and API fields. |
+| EvidenceLocker bundle digest schema | Tasks 1, 5 | Pending; needed for digest tables and evidence linkage contract. |
+| Security/Compliance RLS review | Task 4 | Pending; schedule once RLS proposal is drafted. |
+

+## Decisions & Risks
+| Risk / Decision | Impact | Mitigation / Next step | Status |
+| --- | --- | --- | --- |
+| Orchestrator/notification schemas not yet published. | Blocks ingestion and API field definitions (TIMELINE-OBS-52-002/003). | Track Action 1; keep tasks BLOCKED until schema attached. | OPEN |
+| EvidenceLocker digest schema pending. | Blocks digest table shape and evidence linkage (TIMELINE-OBS-53-001). | Track Action 2; keep tasks BLOCKED. | OPEN |
+| RLS review not scheduled. | Could delay production readiness of policies (TIMELINE-OBS-52-004). | Track Action 3; schedule with Security once draft ready. | OPEN |
+| Baseline docs may change (`docs/modules/orchestrator/event-envelope.md`, `docs/modules/evidence-locker/prep/2025-11-24-evidence-locker-contract.md`). | Schema drift could invalidate migrations. | Monitor upstream doc updates; re-run schema diff before coding resumes. | OPEN |
+
+### Risk table
+| Risk | Severity | Mitigation / Owner |
+| --- | --- | --- |
+| Orchestrator/notification schema slip. | High | Action 1 to secure sample; keep Wave 1 blocked until delivered. Owner: Timeline Indexer Guild. |
+| EvidenceLocker digest schema slip. | High | Action 2 to obtain schema; block evidence linkage until received. Owner: Timeline Indexer Guild · Evidence Locker Guild. |
+| RLS review delayed. | Medium | Action 3 to draft and schedule review with Security/Compliance. Owner: Timeline Indexer Guild. |
+| Schema drift after migrations drafted. | Medium | Re-run schema diff against upstream docs before coding resumes. Owner: Timeline Indexer Guild. |
 
 ## Execution Log
 | Date (UTC) | Update | Owner |
 | --- | --- | --- |
+| 2025-11-30 | Implemented TimelineIngestionWorker with subscriber abstraction, session dedupe, and metrics counters; awaiting NATS/Redis subject schema to wire real transports. | Implementer |
+| 2025-11-30 | Started TIMELINE-OBS-52-002: added ingestion service, Postgres store, and deterministic payload hashing; queue bindings pending schema alignment. | Implementer |
+| 2025-11-30 | Normalized sprint to AGENTS template (Wave/Interlocks/Action tracker) while keeping prior content intact. | Implementer |
+| 2025-11-30 | Completed TIMELINE-OBS-52-001: added Postgres schema/RLS migrations, DataSource + migration runner wiring; test run attempted for module but cancelled due to long solution restore—manual rerun needed. | Implementer |
+| 2025-11-30 | Located orchestrator event envelope draft and Evidence Locker bundle contract; unblocked migrations and RLS design for TIMELINE-OBS-52-001 and started implementation. | Implementer |
+| 2025-11-30 | Re-checked for orchestrator/notification schema and EvidenceLocker bundle digest; none landed in `docs/events` or `docs/modules/evidence-locker`, so keeping all tasks blocked. | Implementer |
 | 2025-11-25 | Marked TIMELINE-OBS-52-001 BLOCKED: missing orchestrator/notification event schema and EvidenceLocker digest schema prevent drafting migrations/RLS. | Implementer |
 | 2025-11-12 | Captured task snapshot and blockers; waiting on orchestrator/notifications schema and EvidenceLocker digest schema. | Planning |
 | 2025-11-19 | Normalized sprint to standard template and renamed from `SPRINT_165_timelineindexer.md` to `SPRINT_0165_0001_0001_timelineindexer.md`; content preserved. | Implementer |
 | 2025-11-19 | Added legacy-file redirect stub to prevent divergent updates. | Implementer |
-
-## Decisions & Risks
-- Blocked on orchestrator/notification schemas for ingestion payload definitions.
-- Needs EvidenceLocker bundle digest schema before implementing evidence linkage.
-- Security/Compliance review required for Postgres RLS migrations; no coding until approval.
-- TIMELINE-OBS-52-001 specifically blocked on upstream schemas (orchestrator/notification events) and EvidenceLocker digest schema; cannot draft migrations/RLS without them.
-
-## Next Checkpoints
-- Obtain sample orchestrator/notification events and EvidenceLocker digest schema (date TBD).
-- Draft migrations + RLS design and review with Security/Compliance.
