## Summary

The Claude smoke harness cleanup packet completed with PASS after four reviewed loops, including three review reworks; the earlier plan 0 pair remains as a superseded artifact without a recorded verdict.

## Loop History

| Plan | Review | Verdict | Note |
|------|--------|---------|------|
| `plan_cloud_G07_1.log` | `code_review_cloud_G07_1.log` | FAIL | Added real model/runtime binding, closed preflight, derived verification, and cleanup/publication ownership. |
| `plan_cloud_G10_2.log` | `code_review_cloud_G10_2.log` | FAIL | Corrected terminal timing and Messages route evidence; process-group cleanup remained open. |
| `plan_cloud_G08_3.log` | `code_review_cloud_G09_3.log` | FAIL | Closed most process-group handling, but normal leader exit, early-signal ownership, and readiness remained incomplete. |
| `plan_cloud_G08_4.log` | `code_review_cloud_G09_4.log` | PASS | Unified bounded group settlement and deterministic cleanup fixtures passed fresh review. |

## Implementation/Cleanup

- Unified normal, non-zero, and signal exits through one idempotent bounded TERM-to-KILL process-group settlement path.
- Deferred signals received before `Popen` ownership publication and serviced them immediately after child assignment.
- Added race-safe descendant readiness plus leader-exit, early-signal, and TERM-resistant lifecycle coverage.
- Preserved raw capture removal, atomic publication cleanup, production-faithful terminal timing, the 401/405 Messages route fence, model binding, and derived verifier evidence.
- Corrected the active review artifact's stale empty-output summaries to include the actual self-test success log lines.

## Final Verification

- `bash -c 'set -euo pipefail; shopt -s nullglob; candidates=(agent-task/m-iop-owned-single-request-agent-execution/22_*/complete.log agent-task/m-iop-owned-single-request-agent-execution/22+*/complete.log agent-task/archive/*/*/m-iop-owned-single-request-agent-execution/22_*/complete.log agent-task/archive/*/*/m-iop-owned-single-request-agent-execution/22+*/complete.log); printf "%s\n" "${candidates[@]}"; ((${#candidates[@]} == 1))'` - PASS; exactly one archived task-22 completion dependency was found.
- `bash -n scripts/e2e-single-request-claude.sh` - PASS with no output.
- `bash -c 'set -euo pipefail; for attempt in 1 2 3; do ./scripts/e2e-single-request-claude.sh --self-test; done'` - PASS; all three fresh credential-free runs emitted the expected success line.
- `make test-single-request-claude-smoke-self-test` - PASS through the repository Make entry point.
- Process lifecycle inventory - PASS; all three fixture families are present and the direct wait is not an immediate supervisor exit.
- Model and verifier inventory - PASS; `ANTHROPIC_MODEL` uses the requested model and verifier evidence is derived.
- Make target/input inventory - PASS; the four isolated targets use only caller-supplied inputs.
- Aggregate isolation check - PASS; no aggregate target invokes the credentialed smoke run.
- `git diff --check` - PASS with no whitespace errors.

## Residual Nits

- None.

## Follow-up Work

- Actual Claude/Mac S12 qualification remains owned by its dedicated external execution task; this completion closes only the repository-owned credential-free harness and cleanup oracle.
