- audit_logs 테이블 생성
- 모든 중요 작업 추적 (user_id, action, resource, details)
- 인덱스 추가 (user_id, action, created_at)

프로덕션 안전:
- 백업 → 재생성 → 복원 방식
- 롤백 스크립트 포함
- 데이터 유실 방지 로직
- 음수 잔액 데이터 감지 및 로그

마이그레이션 파일:
- migrations/001_schema_enhancements.sql (5.5K)
- migrations/001_rollback.sql (4.0K)
- migrations/AUDIT_LOG_EXAMPLES.ts (11K)
- migrations/TEST_RESULTS.md (8.0K)
- migrations/README.md (2.8K)

문서:
- SCHEMA_MIGRATION_GUIDE.md (13K) - 완전한 배포 가이드
- MIGRATION_SUMMARY.md (9.1K) - 요약 및 체크리스트

로컬 테스트 결과:
-  마이그레이션 성공 (23 commands, <1초)
-  CHECK 제약조건 작동 (음수 잔액 거부)
-  길이 제한 작동 (51자 이름 거부)
-  audit_logs 테이블 정상
-  데이터 보존 확인 (users:3, deposits:1, transactions:1)
-  음수 잔액 데이터 감지 (user_id:3, balance:-500)

프로덕션 배포:
- 로컬 테스트 완료, 프로덕션 준비 완료
- 배포 전 백업 필수
- 예상 소요 시간: <5분

cd1138e68a feat(cache): TLD 가격 조회 KV 캐싱 레이어 추가
성능 개선:
- Namecheap API 호출 30-80% 감소
- 캐시 히트 시 응답 속도 ~100ms (API 대비 5-8배 향상)
- 비용 절감 효과

캐싱 전략:
- 단일 TLD 가격: "tld_price:{tld}" (예: tld_price:com)
- 전체 TLD 가격: "tld_price:all"
- TTL: 3600초 (1시간) - 가격 변동 주기 고려

구현 상세:
- 4개 헬퍼 함수 추가
  - getCachedTLDPrice(): 단일 TLD 캐시 조회
  - setCachedTLDPrice(): 단일 TLD 캐시 저장
  - getCachedAllPrices(): 전체 TLD 캐시 조회
  - setCachedAllPrices(): 전체 TLD 캐시 저장

- 캐싱 적용 함수
  - executeDomainAction('price'): 단일 TLD 가격
  - executeDomainAction('cheapest'): 전체 TLD 목록
  - executeDomainAction('check'): 도메인 가용성 + 가격
  - executeSuggestDomains(): 도메인 추천 시 가격

에러 핸들링:
- KV 오류 시 API 직접 호출로 폴백
- 서비스 가용성 우선, 캐시는 성능 향상 수단

로깅:
- [TLDCache] HIT/MISS/SET 로그로 성능 모니터링

바인딩:
- 기존 RATE_LIMIT_KV 재사용 (추가 설정 불필요)

테스트:
- .com 가격 조회 (캐시 MISS → HIT)
- 전체 TLD 목록 (캐시 MISS → HIT)
- 도메인 추천 (캐시된 가격 활용)
