## Summary

Completed the fifth plan/review loop with a final PASS after pinning the current 300-row baseline, a 437-row effective disposition matrix, exact predecessor provenance, and a deletion-safe pre-deletion receipt without requiring a raw owner bundle.

## Loop History

| Plan | Review | Verdict | Note |
|------|--------|---------|------|
| `plan_cloud_G09_0.log` | `code_review_cloud_G09_0.log` | not reviewed | The initial receipt concept was superseded before implementation. |
| `plan_cloud_G09_1.log` | `code_review_cloud_G09_1.log` | not reviewed | The prior generic-node boundary assumption was superseded. |
| `plan_cloud_G09_2.log` | `code_review_cloud_G09_2.log` | not reviewed | The live-source-after-deletion design was superseded. |
| `plan_cloud_G09_3.log` | `code_review_cloud_G09_3.log` | FAIL | The review rejected the stale 303-row current baseline, prose-sensitive Task 09 verdict check, and unavailable raw owner-bundle requirement. |
| `plan_cloud_G09_4.log` | `code_review_cloud_G09_4.log` | PASS | Current-baseline copies, effective matrix, strict receipt, deletion-safe verifier, and audit evidence passed review. |

## Implementation and Cleanup

- Copied the six current source evidence files byte-for-byte into the task directory and generated seven canonical basename-only SHA-256 sidecars.
- Materialized the sorted 437-row effective disposition matrix from 300 manifest rows, 137 delta decisions, and 137 source-disjoint addendum rows.
- Added a strict English pre-deletion receipt binding current and historical provenance, Task 06 owner-transfer evidence, Task 10 import-audit evidence, rollback, promotion, and lock identities.
- Added fail-closed `materialize`, `check-live`, and deletion-safe `check-archived` verification modes plus deterministic audit markers with no raw owner bundle, host path, secret, or external mutation.

## Final Verification

- `go version && test "$(go env GOMOD)" = "$PWD/go.mod"` - PASS; Go 1.26.2 on linux/arm64 and the current workspace module were confirmed.
- `python3 scripts/verify_iop_agent_chronos_boundary_test.py` - PASS; all 17 boundary verifier tests passed.
- `python3 scripts/verify-iop-agent-chronos-boundary.py ... --check-only` - PASS; `manifest_rows=300 delta_rows=137 addendum_rows=137 state_records=12`.
- `python3 .../verify-pre-deletion-receipt-v1.py materialize --workspace . && python3 .../verify-pre-deletion-receipt-v1.py check-live --workspace . && python3 .../verify-pre-deletion-receipt-v1.py check-archived --workspace .` - PASS; all modes reported 300/137/137 inputs and a 437-row effective matrix.
- Isolated deletion-safe archive reproduction - PASS; `check-archived` succeeded in a temporary workspace containing no live fixture inputs, then rejected a one-byte matrix corruption with a digest mismatch.
- `go test -count=1 ./packages/go/execution ./packages/go/streamgate ./packages/go/config` - PASS.
- `make test` - PASS; all repository Go packages passed.
- `git diff --check` - PASS; no whitespace errors.
