## 요약

OpenAI-compatible response mode selector와 sideband public surface 제거 작업을 1회 리뷰 루프로 검증했고 최종 판정은 PASS다.

## 루프 이력

| Plan | Review | Verdict | 메모 |
|------|--------|---------|------|
| `plan_cloud_G07_0.log` | `code_review_cloud_G07_0.log` | PASS | caller-facing selector 제거, metadata route 불변성, sideband surface 제거, usage metric label 정리를 검증했다. |

## 구현/정리 내용

- Chat/Responses handler에서 caller metadata 기반 response mode parsing/rejection/branch와 sideband response path를 제거했다.
- Provider passthrough response surface에서 `X-IOP-Response-Mode`, sideband SSE event/envelope/body metadata injection을 제거하고, response path를 route/provider capability 기준으로만 정리했다.
- Selector-like metadata negative test, passthrough body immutability/no-extension test, internal `response_mode` metric label 문서를 갱신했다.
