## 완료 일시

2026-06-20

## 요약

Runner socket session lifecycle 보강을 2회 리뷰 루프로 완료했다. 최종 판정은 PASS다.

## 루프 이력

| Plan | Review | Verdict | 메모 |
|------|--------|---------|------|
| `plan_cloud_G07_0.log` | `code_review_cloud_G07_0.log` | FAIL | duplicate runner client replacement에서 old client close가 server mutex 재진입 deadlock을 만들 수 있어 follow-up 필요 |
| `plan_local_G06_1.log` | `code_review_local_G06_1.log` | PASS | old client close를 mutex 밖으로 이동하고 production-style disconnect listener 재진입 테스트로 고정 |

## 구현/정리 내용

- `services/core/internal/runnersocket.Server.setClient`가 새 client를 map에 저장하고 lock을 해제한 뒤 old client를 닫도록 정리했다.
- duplicate replacement 중 old client disconnect listener가 `removeClient`로 재진입해도 current client와 registry 상태를 덮지 않는 테스트를 추가했다.
- Go/Dart socket session lifecycle 검증으로 SDD `S02` evidence를 충족했다.

## 최종 검증

- `cd services/core && go test -count=1 ./internal/runnersocket` - PASS; `ok github.com/toki/oto/services/core/internal/runnersocket 0.048s`
- `cd services/core && go test -count=1 ./...` - PASS; core packages all passed, including `internal/runnersocket`
- `cd apps/runner && dart test test/oto_agent_registration_test.dart test/oto_server_connection_smoke_test.dart` - PASS; `00:07 +50: All tests passed!`
- `cd apps/runner && dart analyze` - PASS; `No issues found!`
