# Handoff: Chronos Extraction Decoupling Ownership Boundary

> D04 전환 경계 정정: Chronos Server와 독립 Chronos Node가 loop, agent, workspace/tool, terminal/PTY, remote host control을 소유한다. Chronos는 필요할 때 IOP external inference API의 일반 client로 작동할 수 있지만, IOP에는 Chronos bridge, control hook, API, proto, config, target registry가 존재하지 않는다.

- 작성일: 2026-07-31 (2026-08-02 D04 정리)
- 현재 타겟: IOP standalone surface 제거 및 D04 경계 수립
- 상태: D04 분리 진행 중
- 기록 위치: IOP 선행 분리 원본은 IOP Roadmap/SDD에, 완료 뒤 제품 개발 원본은 Chronos Roadmap에 둔다.

## 사용자 확정 사항

1. `/config/workspace/iop-s0`에서 진행했던 `IOP Agent CLI Runtime` Milestone은 기존 범위대로 완료됐다.
2. Chronos Server 및 독립 Chronos Node가 loop/agent/workspace/tool/terminal/PTY/remote host control 소유권을 전적으로 관리한다.
3. Chronos는 IOP external inference API의 일반 client로 작동할 수 있으나, IOP Node는 Chronos bridge나 control hook을 갖지 않는다.
4. Task 10은 `agent-contract/inner/iop-agent-cli-runtime.md`를 물리 삭제한다.
5. evidence 순서는 다음과 같이 관리하며 이 단계에서 최종 완료를 선포하지 않는다:
   - task 10: contract 원문 및 transitional runtime/CLI provider 물리 삭제
   - task 13: effective matrix와 pre-deletion receipt 생성
   - task 14: 잔여 migration surface 최종 삭제
   - task 15: `HANDOFF.md` final composite receipt 작성

## 프로젝트 이름과 상징

프로젝트명은 **Chronos**로 확정한다.

- 영문 문구: `Chronos — Take your time back.`
- 한국어 문구: `일은 맡기고, 시간은 되찾다.`
- 저장소 기본명: `chronos`
- CLI 기본명: `chronos`
- daemon 기본명: `chronosd`
- runtime package/product family: `chronos-runtime`

## 최종 방향

Chronos Server 및 독립 Chronos Node가 agent control과 workspace execution을 독립 수행한다.
IOP는 external inference API와 model/provider/device execution, cancel, status, usage lifecycle만 제공한다.

```text
Chronos Server / Chronos Node -> loop, agent, workspace/tool, terminal/PTY, remote control
Chronos -> optional ordinary client of IOP external inference API
IOP -> no Chronos bridge/API/proto/config/target/registry/control hook
```

책임은 다음과 같이 고정한다.

| 소유자 | 책임 |
|---|---|
| `Chronos` | standalone runtime core, CLI/daemon, local control, workflow adapter, durable state/replay, scoped execution |
| IOP | external inference API, model/provider execution, cancel, status, usage lifecycle |

## Next Steps and Evidence Sequence

1. Task 10은 `agent-contract/inner/iop-agent-cli-runtime.md`를 물리 삭제한다.
2. Task 13: effective matrix와 pre-deletion receipt 기록.
3. Task 14: 남은 migration surface 최종 삭제.
4. Task 15: `HANDOFF.md` final composite receipt 작성.
