## Summary

Completed the CAS-backed project-log journal and exactly-once archive reconciliation child task after five review loops; final verdict: PASS.

## Loop History

| Plan | Review | Verdict | Notes |
|------|--------|---------|-------|
| `plan_local_G08_0.log` | `code_review_cloud_G08_0.log` | FAIL | Required journal-owned sequence assignment, complete archive verification, concurrent-suffix pruning, and collision-safe journal identity. |
| `plan_local_G08_1.log` | `code_review_cloud_G09_1.log` | FAIL | Required pre-prune artifact verification and strict persisted journal validation. |
| `plan_cloud_G09_2.log` | `code_review_cloud_G09_2.log` | FAIL | Required exclusive archive ordinal ownership and typed malformed-intent rejection. |
| `plan_cloud_G09_3.log` | `code_review_cloud_G09_3.log` | FAIL | Required typed rejection for checksum-admitted malformed JSONL. |
| `plan_cloud_G05_4.log` | `code_review_cloud_G05_4.log` | PASS | Confirmed typed malformed-JSONL conflict handling, exact no-mutation regressions, and the full declared verification matrix. |

## Implementation and Cleanup

- Implemented the CAS-backed append-only project-log journal with validated project/workspace identity, monotonic sequence assignment, bounded conflict retry, and replay.
- Implemented terminal archive intent, redacted JSONL/timeline, manifest verification, exact-prefix CAS pruning, restart reconciliation, and immutable ordinal reuse under a shared advisory lock.
- Classified persisted archive corruption through typed incomplete/conflict errors, including malformed intent and checksum-admitted malformed JSONL, without rewriting artifacts or journal evidence.
- Added deterministic Archive/Reconcile, corruption, concurrent append, concurrent archive, retry, multi-ordinal, and byte/revision retention regressions.

## Final Verification

- `go test -count=1 ./apps/agent/internal/projectlog -run 'Test(Archive|Reconcile)RejectsMalformedJSONLWithMatchingIntentChecksum'` - PASS; `ok iop/apps/agent/internal/projectlog 0.108s`.
- `gofmt -w apps/agent/internal/projectlog/store.go apps/agent/internal/projectlog/store_test.go` - PASS; no output.
- `go test -count=1 ./apps/agent/internal/projectlog -run 'TestStore|TestArchive|TestReconcile'` - PASS; `ok iop/apps/agent/internal/projectlog 0.535s`.
- `go test -count=1 ./apps/agent/internal/projectlog` - PASS; `ok iop/apps/agent/internal/projectlog 0.497s`.
- `go test -count=1 -race ./apps/agent/internal/projectlog ./packages/go/agentstate` - PASS; `projectlog 2.222s`, `agentstate 1.107s`.
- `go vet ./apps/agent/internal/projectlog` - PASS; no output.
- `test -z "$(gofmt -d apps/agent/internal/projectlog/store.go apps/agent/internal/projectlog/store_test.go)"` - PASS; no output.
- `git diff --check` - PASS; no output.

## Remaining Nits

- None.

## Follow-up Work

- None for this child task. EventSink mapping, WORK_LOG projection, and the complete S12 dynamic frontier remain owned by later milestone children.
