# Final handoff residual·sensitive closure

## For the Implementing Agent

`CODE_REVIEW-cloud-G07.md`의 implementation-owned 섹션 작성은 필수다. encoded predecessor의 exact PASS를 확인하고 이 child 범위만 구현·검증한다. active pair를 유지해 review 준비 완료를 보고하며 finalization은 code-review agent만 수행한다. 차단되면 질문하거나 상태를 분류하지 말고 blocker, 실제 명령/출력, 재개 조건만 evidence 필드에 기록한다.

## Background

receipt, migration cleanup, residual/sensitive scans와 lock condition을 최종 감사해 S05 handoff-ready evidence를 닫는다.

## Roadmap Targets

- Milestone: `agent-roadmap/phase/automation-runtime-bridge/milestones/iop-agent-chronos-extraction-decoupling.md`
- Milestone link: [Milestone 문서](agent-roadmap/phase/automation-runtime-bridge/milestones/iop-agent-chronos-extraction-decoupling.md)
- Task ids:
  - `handoff-gate`: 전체 state 이전, 양쪽 검증, rollback, downstream lock identity를 포함한 receipt 확정
- Completion mode: check-on-pass

## Analysis

### Files Read

- `agent-roadmap/phase/automation-runtime-bridge/milestones/iop-agent-chronos-extraction-decoupling.md`
- `agent-roadmap/sdd/automation-runtime-bridge/iop-agent-chronos-extraction-decoupling/SDD.md`
- `agent-task/m-iop-agent-chronos-extraction-decoupling/13+09,10_receipt_lock_audit/plan_cloud_G09_0.log`

### SDD Criteria

- SDD `agent-roadmap/sdd/automation-runtime-bridge/iop-agent-chronos-extraction-decoupling/SDD.md`는 `[승인됨]`, 잠금 `해제` 상태다.
- Target은 Acceptance Scenario `S05`와 Milestone Task `handoff-gate`; Evidence Map row는 전체 상태 fixture, final cross-repo matrix와 lock check를 거쳐 Completion-citable receipt를 요구한다.
- 이 closure child는 receipt provenance, active residual, sensitive fields, repository mutation 0과 canonical promotion pending을 최종 재검증해 `handoff-gate` 완료 evidence를 판정한다.

### Verification Context

- Handoff는 없다. Milestone, 승인 SDD와 보존된 parent plan을 읽었고 predecessor `14+13_remove_migration_surface`의 exact PASS `complete.log`는 missing이다.
- gap은 receipt/audit와 migration cleanup이 아직 완료되지 않았다는 점이다. sensitive scan은 receipt가 있는 child 13과 final audit child 15를 함께 검사한다.
- Chronos/canonical IOP는 read-only이며 import/unlock/mutation은 금지한다. Confidence는 medium-high이고 predecessor evidence가 모두 존재할 때 deterministic closure가 가능하다.

### Test Coverage Gaps

- Chronos import/build는 downstream 범위다. 이 child는 mutation 0과 canonical promotion pending을 검증한다.

### Symbol References

- runtime symbol 변경 없음.

### Split Judgment

- 이 closure child만 handoff-gate Roadmap Task를 닫는다.
- Predecessor `14`의 active/archived exact PASS `complete.log`는 missing이다. PASS evidence는 receipt provenance, active/sensitive residual 0, external mutation 0와 canonical promotion pending이다.

### Scope Rationale

- Milestone close, locks.yaml mutation, Chronos unlock/import는 수행하지 않는다.

### Final Routing

- `evaluation_mode=isolated-reassessment`, finalizer=`finalize-task-policy.sh`, mode=`pair`.
- Build closures 모두 true. Scores=`1,0,2,2,2`, grade=`G07`, base/route=`local-fit`, lane=`local`.
- Review closures 모두 true. Scores=`1,0,2,2,2`, route=`official-review`, lane=`cloud`, grade=`G07`.
- `large_indivisible_context=false`; positive loop risks=`boundary_contract` (1); `review_rework_count=0`; `evidence_integrity_failure=false`; capability gap 없음.
- Canonical files: `PLAN-local-G07.md`, `CODE_REVIEW-cloud-G07.md`.

## Dependencies and Execution Order

1. `14+13_remove_migration_surface` must each have exactly one matching PASS `complete.log`; all are currently missing.
2. Resolve only those exact predecessor completion artifacts, then implement this child scope.

## Implementation Checklist

- [ ] Refuse to start until predecessor 14+13_remove_migration_surface has an exact PASS complete.log.
- [ ] Recheck receipt/digest provenance and run the original final active-runtime, sensitive-data, repository, and lock audits.
- [ ] Record zero residuals, zero sensitive fields, zero Chronos mutations, and explicit canonical promotion pending in handoff-audit.log.
- [ ] Fill implementation-owned sections in CODE_REVIEW-*-G??.md with actual implementation notes and verification output.

### [TEST-4] Final residual/sensitive/closure audit

**Problem**

receipt가 완전해도 active source residual이나 sensitive value가 남으면 handoff-ready가 아니다.

```text
# State machine: decoupled -> handoff-ready
final receipt + lock synchronization evidence
```

**Solution**

active product/contract/spec/rule paths의 standalone workflow residual, Chronos application import, task artifact sensitive patterns, broken active links를 검사한다. governance Milestone/SDD/receipt의 historical names는 exact allowed references로 기록한다.

```text
# after: handoff-audit.log
active_runtime_residuals=0
sensitive_receipt_fields=0
chronos_mutations=0
lock_identity_match=1
canonical_promotion_pending_is_explicit=1
```

**Modified Files and Checklist**

- [ ] `agent-task/m-iop-agent-chronos-extraction-decoupling/15+14_handoff_closure/handoff-audit.log` — final exact outputs.
- [ ] `agent-task/m-iop-agent-chronos-extraction-decoupling/15+14_handoff_closure/CODE_REVIEW-cloud-G07.md` — actual evidence.

**Test Strategy**

- deterministic scans and fresh Go/readability checks; no cached result.

**Verification**

- `test -z "$(rg --sort path -n 'apps/agent|packages/go/agent(runtime|provider|task|state|config|guard|policy|workspace)|IopAgentPanel|iop-agent (serve|task-loop)|git\.toki-labs\.com/toki/chronos' apps packages cmd configs proto agent-contract agent-spec agent-ops/rules/project README.md)"`
- `test -z "$(rg --sort path -n '/home/|/Users/|state_root: /|overlay_root: /|token:|credential:|secret:|private_key:' agent-task/m-iop-agent-chronos-extraction-decoupling/13+09,10_receipt_lock_audit agent-task/m-iop-agent-chronos-extraction-decoupling/15+14_handoff_closure)"`
- `git diff --check`

## Final Verification

1. Confirm exact PASS `complete.log` for `14+13_remove_migration_surface`.
2. `test -z "$(rg --sort path -n 'apps/agent|packages/go/agent(runtime|provider|task|state|config|guard|policy|workspace)|IopAgentPanel|iop-agent (serve|task-loop)|git\.toki-labs\.com/toki/chronos' apps packages cmd configs proto agent-contract agent-spec agent-ops/rules/project README.md)"`

4. `git diff --check`

Commands containing `go test -count=1` require fresh output; all other checks are rerun against the current checkout.

After completing all code changes, fill implementation-owned sections in `CODE_REVIEW-*-G??.md`.
