# No-Chronos connection과 provider-only Node final closure

## For the Implementing Agent

`CODE_REVIEW-cloud-G08.md`의 implementation-owned 섹션 작성은 필수다. encoded predecessor의 exact PASS와 HANDOFF의 durable receipt pointer를 확인한 뒤 product tree와 receipt를 read-only로 감사하고 fresh verification output을 기록한다. active pair를 유지해 review 준비 완료만 보고하며 finalization은 code-review agent만 수행한다. 차단되면 사용자에게 묻거나 다음 상태를 분류하지 말고 exact blocker, 시도한 명령/출력, 재개 조건만 implementation-owned evidence에 기록하며 archive, `complete.log`, roadmap/lock mutation이나 control-plane stop file을 만들지 않는다.

## Background

IOP 완료 조건은 단순히 agent-named directory를 지우는 것이 아니라 effective matrix의 모든 `transfer-remove` 경로가 사라지고, 남은 Node가 model/provider/device operation만 수행하며 Chronos 연결·agent/terminal/workspace 제어 surface를 갖지 않는 것이다. 이 final gate는 receipt provenance, live-tree disposition, fresh provider/Node regressions와 formal lock identity를 한 번 더 결합해 Milestone handoff evidence를 만든다.

## 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 상태·양쪽 검증·rollback·downstream lock identity를 추적하는 final transfer receipt
- Completion mode: check-on-pass

## Archive Evidence Snapshot

- `agent-task/m-iop-agent-chronos-extraction-decoupling/15+14_handoff_closure/plan_local_G07_0.log`와 `code_review_cloud_G07_0.log`는 D02 generic Node control 기준의 미착수 final audit pair다. implementation evidence와 verdict가 없고 D04가 경계를 대체했다.
- Required/Suggested/Nit finding이나 Roadmap completion은 없다. receipt provenance, external mutation 0, canonical promotion pending이라는 audit 구조만 승계한다.

### SDD Criteria

- SDD는 `[승인됨]`, 잠금 `해제`이며 direct target은 S05 / Milestone Task `handoff-gate`다.
- S05 Evidence Map은 전체 상태 이전 fixture, final cross-repo matrix와 lock check를 Roadmap Completion에서 인용 가능한 receipt로 요구한다.
- S01-S04의 upstream closure도 최종 receipt의 유효 조건이다. Task 10 PASS가 S03 `decouple`과 S04 `retain-node`를 함께 닫고 task 13이 S01 `inventory`를 닫으며, task 14는 receipt 이후 migration surface를 제거한다. 따라서 effective matrix live-tree audit, bundle/state/provenance digest, removed path 0, provider-only Node regression, Chronos connection 0과 external mutation 0을 하나의 TEST-1 gate로 검증한다.

### Verification Context

- Handoff는 없다. active/archive candidate에서 predecessor `14+13_remove_migration_surface`의 exact `complete.log`를 확인했으나 현재 missing이다.
- 14가 만드는 `HANDOFF.md` stable fields에서 exact archived 13 receipt를 resolve한다. receipt는 original manifest, boundary delta, effective matrix, bundle/state digest와 matrix path를 제공하며 canonical promotion은 pending이다.
- Local test profiles는 current checkout, Go module, no external service/credential의 Node/provider/full regressions를 요구한다. cache를 사용하지 않으며 `go test -count=1`을 fresh 실행한다.
- External preflight는 `/config/workspace/chronos`, canonical `/config/workspace/iop`, lock registry의 branch/HEAD/status를 read-only로 capture한다. `iop-s1:` checker result는 `none`, formal `iop:` result는 `rely-on:chronos:chronos-architecture-ownership-boundary`가 expected다. promotion/unlock/import는 수행하지 않는다.
- Linux aarch64, Go `go1.26.2`; 외부 runtime, port, device, credential은 필요 없다. Confidence는 high이며 task 14 PASS만 execution precondition이다.

### Test Coverage Gaps

- 기존 Node/provider tests가 execute/cancel/status/usage/lifecycle와 Edge wire를 검증한다. 어떤 exact retained package가 최종 경계인지 task-10 delta/effective matrix가 source of truth다.
- 부재 불변조건은 unit test만으로 닫히지 않으므로 effective matrix-to-live-tree audit와 deterministic forbidden-reference scan을 추가한다.
- Chronos Server/Node/loop/agent/terminal은 downstream 미구현 범위이므로 이 task는 ownership 문구와 no-mutation만 검증한다.

### Symbol References

- Forbidden product paths/symbols: `apps/agent`, `packages/go/agent*`, `packages/go/provider/cli`, `proto/iop/agent.proto`, `CLIAdapterConfig`, `CLIProfileConfig`, `AgentUsageStatus`, `persistent_terminal`, `persistent_process`, `TERMINATE_SESSION`, `SESSION_LIST`, `USAGE_STATUS`, `codex-app-server`, `opencode-sse`, `quota-probe`.
- Forbidden Chronos connections/imports: `git.toki-labs.com/toki/chronos`, `agent_bridge`, Chronos bridge/control/connector/gateway/target/registry/server/node product symbols or config/proto fields.
- Allowed boundary는 effective matrix의 `retain-rewrite+iop` final paths와 model/provider/device execute/cancel/status/usage/lifecycle vocabulary뿐이다.

### Split Judgment

- Predecessor 14의 active/archive exact PASS `complete.log`는 missing이다.
- Stable invariant는 receipt의 effective dispositions가 live tree와 일치하고 IOP Node가 provider-only이면서 모든 Chronos/agent/terminal/workspace connection surface가 0인 것이다.
- receipt integrity, tree absence, focused/full regression과 external lock identity가 함께 있어야 handoff-ready를 판정할 수 있으므로 더 나누지 않는다. PASS evidence는 digest match, transfer-remove residual 0, retained-path mismatch 0, forbidden surface 0, fresh test PASS, external mutation 0이다.

### Scope Rationale

- 이 task는 evidence-only final gate다. product code, README/HANDOFF, contracts/specs, roadmap/SDD, external repositories와 lock registry를 수정하지 않는다.
- Canonical IOP promotion, Milestone 상태 동기화와 Chronos lock 해제는 reviewed commit 이후 runtime/update-roadmap 책임이다.
- Chronos Server/Node/loop/agent/terminal 설계·구현과 bundle import는 downstream Chronos Milestone 범위다.

### Final Routing

- `evaluation_mode=isolated-reassessment`, finalizer=`finalize-task-policy.sh`, mode=`pair`.
- Build closures 모두 true. Scores=`2,0,2,2,2`, grade=`G08`, base/route=`local-fit`, lane=`local`.
- Review closures 모두 true. Scores=`2,0,2,2,2`, route=`official-review`, lane=`cloud`, grade=`G08`.
- `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-G08.md`, `CODE_REVIEW-cloud-G08.md`.

## Dependencies and Execution Order

1. `14+13_remove_migration_surface` must have exactly one matching PASS `complete.log`; it is currently missing.
2. Resolve HANDOFF -> archived receipt -> effective matrix and verify the complete provenance chain.
3. Audit live-tree disposition, provider-only Node regressions, forbidden product surfaces and external identities read-only.
4. Write only this task's final audit log and implementation-owned review evidence.

## Implementation Checklist

- [ ] Refuse to start until predecessor 14+13_remove_migration_surface has an exact PASS complete.log and HANDOFF resolves one durable archived receipt/effective matrix.
- [ ] Verify task-13 pre-deletion original/bundle/state digest-match evidence, independently recompute the archived delta/effective digests, then audit every effective transfer-remove and retain-rewrite path against the live IOP tree.
- [ ] Run fresh provider/Node/full regressions plus exact no-Agent, no-terminal/workspace-control, and no-Chronos-connection/import scans.
- [ ] Record provider-only ownership, zero residual/connection/external mutation, rollback, formal lock identity, and canonical-promotion-pending results in the final audit log.
- [ ] Fill implementation-owned sections in CODE_REVIEW-*-G??.md with actual implementation notes and verification output.

### [TEST-1] S01-S05 final handoff gate

**Problem**

Individual predecessor PASS logs do not alone prove that the receipt still matches the live tree or that a retained neutral package did not preserve CLI agent/session/terminal/workspace or Chronos connection semantics.

```text
# SDD handoff-ready
effective dispositions match live IOP
IOP Node owns model/provider/device operations only
Chronos connections and repository mutations are zero
```

**Solution**

HANDOFF pointer에서 receipt/effective matrix를 resolve하고 모든 digest와 row counts를 다시 확인한다. `transfer-remove` original paths는 모두 absent, `retain-rewrite+iop` final paths는 모두 present이며 허용된 provider boundary만 포함해야 한다. focused/full tests와 forbidden-reference scan, formal lock/canonical identities를 한 audit log에 actual stdout/stderr로 기록한다.

```text
# after: handoff-audit.log
effective_matrix_digest_match=1
transfer_remove_residuals=0
retained_path_mismatches=0
iop_node_owner=model-provider-device
chronos_connection_surfaces=0
cli_agent_terminal_workspace_surfaces=0
chronos_repository_mutations=0
canonical_promotion=pending
```

**Modified Files and Checklist**

- [ ] `agent-task/m-iop-agent-chronos-extraction-decoupling/15+14_handoff_closure/handoff-audit.log` — final receipt/tree/test/lock evidence.

**Test Strategy**

- Effective matrix path audit and deterministic forbidden scan cover negative ownership conditions. Existing fresh Node/provider/full Go suites cover retained behavior and Edge wire compatibility.

**Verification**

- Resolve one HANDOFF receipt/effective matrix, verify task-13 pre-deletion original/bundle/state digest-match evidence, and independently recompute the archived delta/effective digests and stable receipt fields.
- Audit every `transfer-remove` original path absent and every `retain-rewrite+iop` nonempty final path present; require residual/mismatch/unclassified/duplicate counts 0.

## Final Verification

1. Confirm exactly one PASS `complete.log` for encoded predecessor `14+13_remove_migration_surface` and resolve exactly one workspace-relative HANDOFF receipt/effective matrix chain.
2. Verify task-13 pre-deletion audit recorded original manifest, bundle, state schema and state fixture `*_digest_match=1`; independently recompute and compare the still-archived boundary delta and effective matrix digests.
3. Audit every effective `transfer-remove` original path as absent and every `retain-rewrite+iop` nonempty final path as present; require `transfer_remove_residuals=0`, `retained_path_mismatches=0`, `unclassified_paths=0`, `duplicate_paths=0`.
