## 요약

S06 consumer semantic/intent 책임 경계와 S07 mixed policy/single-buffer 경계를 public API만으로 검증하는 test-only closure를 PASS로 종결했다.

## 루프 이력

| Plan | Review | Verdict | 메모 |
|------|--------|---------|------|
| `plan_local_G05_0.log` (본 작업) | `code_review_cloud_G06_0.log` (대기) | PASS | TEST-1 20개 subtest, TEST-2 5개 subtest 전체 통과. 생산 코드 변경 없음. |

## 구현/정리 내용

- `packages/go/streamgate/consumer_contract_test.go`에 `semanticFilter` fixture 추가: `Filter` 인터페이스만 구현, mutation/retry/rebuild/dispatch/submit callback 없음.
- `TestConsumerSemanticIntentParity`: OpenAI/agent family 간 pass, violation(no-intent), violation(with-intent), fatal, replacement, unmatched/matched provider error 행렬을 검증하고 cross-family `ArbitrationResult` 동일성을 증명. intent priority mismatch 거절, non-violation kind에 intent 전달 거절 검증 포함.
- `TestConsumerPolicyMixedPublicIntegration`: rolling/terminal-gate/fragment-gate/provider-error 필터를 mixed enforcement(blocking + observe-only)로 등록하고, registry → resolve → plan → bind epoch → coordinator.Evaluate/Submit 경로를 public API만으로 실행. single-buffer/commit 경계(Evaluate == Submit result) 증명.
- 생산 코드 수정 없음.

## 최종 검증
