Estimated code review effort: 4 (Complex) | ~45 minutes Mergeability Score: 🟡 Moderate · up to The PR’s idempotency behavior can reject a valid retry after the embedding model changes because the event key and payload use different identity rules; merge should wait for explicit contract confirmation or an adjustment to the key or validation. The integration test also contains a personal-looking email and depends on seeded data. Sequence Diagram(s)sequenceDiagram

109-122: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winfixture 자체를 검증하는 assert를 정리하고, 새 분기 커버리지를 추가하세요.
Line 109가
result와persisted의 동일성을 확정합니다. 따라서 Line 110-122는 테스트가 직접 build한 fixture 값을 다시 확인하는 검증입니다. 실제 production 동작 검증은 Line 97-108의 인자 검증이 담당합니다.또한
getStatus()와getRetryCount()는 native INSERT의'PENDING',0초기화가 아니라 entity 기본값을 관찰합니다. 이 두 값의 DB 초기화 검증은 통합 테스트에 두는 편이 정확합니다.이번 변경으로 새로 생긴 분기에 대한 테스트가 없습니다. 다음 두 경로를 추가하면 회귀 방지 효과가 큽니다.
findByIdempotencyKey가 빈Optional을 반환하는 경로 →SYNC_EVENT_INCONSISTENT발생 확인.- 기존 event의 payload 또는 aggregate 값이 요청과 다른 경로 →
validateExistingEvent의 예외 발생 확인.테스트 코드 생성이 필요하면 알려주세요.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
payload 전체 일치 비교가 DOCUMENT_VERSION_CREATED에서 정상 재시도를 실패로 만듭니다.
recordDocumentVersionCreated의 idempotency key는 DOCUMENT_VERSION:{id}:DOCUMENT_VERSION_CREATED:{versionNo}입니다. embeddingModelId는 key에 없고 payload에만 있습니다. 따라서 active embedding model이 바뀐 뒤 동일 version에 대한 재시도가 들어오면 key는 같고 payload는 달라져 SYNC_EVENT_INCONSISTENT가 발생합니다. 이때 호출 흐름(문서 업로드)이 실패합니다.
두 가지 해석이 가능합니다.
- model 차이도 원장 충돌로 간주한다 → 현재 코드가 맞습니다. 다만 이 의도를 주석에 명시해야 합니다.
- model 차이는 별개 event로 다뤄야 한다 → idempotency key에
embeddingModelId를 포함해야 합니다.recordDocumentReindexRequested는 이미 model id를 key에 포함하므로 이 방향이 일관됩니다.
의도한 해석을 확정하세요.
♻️ 해석 2를 선택할 경우의 변경안
String idempotencyKey = String.format(
- "%s:%d:%s:%d",
+ "%s:%d:%s:%d:%d",
SyncAggregateType.DOCUMENT_VERSION,
documentVersion.getId(),
SyncEventType.DOCUMENT_VERSION_CREATED,
- documentVersion.getVersionNo()
+ documentVersion.getVersionNo(),
+ embeddingModel.getId()
);이 변경은 SyncEventWriterTest의 기대 key 문자열과 통합 테스트의 key 조립부도 함께 수정해야 합니다.

개인 email 형태의 식별자를 테스트 코드에 고정하지 마세요.
이 문자열은 실제 개인 email 주소 형태입니다. 저장소에 커밋되면 개인 식별 정보가 소스에 남습니다. 또한 이 테스트는 특정 seed row에 결합되어, seed 데이터가 바뀌면 orElseThrow()에서 실패합니다.
테스트 fixture로 사용자를 직접 생성하거나, 예시 도메인(@example.com)을 사용하는 상수로 바꾸세요.
