# Complete - m-iop-agent-chronos-extraction-decoupling/15+14_handoff_closure

## Completion Time

2026-08-02

## Summary

Completed five plan iterations (two superseded before implementation, two failed reviews, and one final PASS) by replacing the contradicted HANDOFF mapping evidence with an exact reproducible stable-receipt-enriched oracle.

## Loop History

| Plan | Review | Verdict | Notes |
|------|--------|---------|-------|
| `plan_local_G07_0.log` | `code_review_cloud_G07_0.log` | SUPERSEDED | Unstarted D02-era final-audit pair replaced after the D04 ownership boundary changed. |
| `plan_local_G08_1.log` | `code_review_cloud_G08_1.log` | SUPERSEDED | Unstarted pointer-chain design replaced before implementation evidence or a verdict existed. |
| `plan_local_G08_2.log` | `code_review_cloud_G08_2.log` | FAIL | The final receipt conflated the 300-row current manifest with the 303-row historical count and lacked a fail-closed mapping check. |
| `plan_cloud_G05_3.log` | `code_review_cloud_G05_3.log` | FAIL | The claimed stable-receipt enrichment was absent from the recorded command, which failed under fresh review. |
| `plan_cloud_G04_4.log` | `code_review_cloud_G04_4.log` | PASS | The exact corrected oracle reproduced all mapped values, digests, row counts, pinned identities, and audit markers. |

## Implementation/Cleanup

- Recorded one runnable HANDOFF-to-receipt mapping oracle that imports the stable receipt JSON and derives all six `real_state_export_*` and `bundle_*` comparison values.
- Preserved `HANDOFF.md` at SHA-256 `d3cc54cb07932f2b4b6cb78e03c17fbb58d040a8c19e4aba6b4d55bdcafb78b0` and `final-handoff-audit.log` at SHA-256 `8e14c350a0dc5cb11fc44a24a11de531f25e8a165d4787161fa373de8e787e7b`.
- Spec update not needed: this follow-up changes review evidence only and does not change runtime behavior or contracts.

## Final Verification

- `python3 - <<'PY' ... HANDOFF-to-receipt mapping oracle ... PY` - PASS; `handoff_receipt_mapping=PASS current_manifest_rows=300 historical_rows=303 stable_receipt_enriched=1`, empty stderr, exit code 0.
- `sha256sum --check ... && python3 - <<'PY' ... final audit marker check ... PY && git diff --check` - PASS; both pinned files reported `OK`, `final_handoff_audit=PASS`, empty stderr, exit code 0.

## Remaining Nits

- None.

## Follow-up Work

- None.
