## 요약

SURFACE_OBS provider-pool sideband/log/usage observation 보강 작업을 1회 리뷰 루프로 PASS 처리했다.

## 루프 이력

| Plan | Review | Verdict | 메모 |
|------|--------|---------|------|
| `plan_local_G07_0.log` | `code_review_local_G07_0.log` | PASS | service dispatch DTO, OpenAI log/sideband boundary, standard response no-sideband regression이 계획과 SDD S09를 충족했다. |

## 구현/정리 내용

- `RunDispatch`와 provider-pool candidate/dispatch 경로에 selected provider id/type 및 execution path 관측 필드를 추가했다.
- OpenAI provider-pool/direct tunnel logs와 sideband observation schema가 provider, adapter, target, execution path, queue reason을 기록하도록 보강했다.
- provider-pool standard Chat response에 `iop_sideband`, `iop.sideband`, `X-IOP-Response-Mode`가 섞이지 않는 회귀 테스트를 추가했다.
