공연·릴리즈 별점 평가(#163) 기능을 위한 Rating 엔티티, target_type enum, 마이그레이션, Repository, ErrorCode를 추가한다. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
RatingService와 DTO를 추가하고 ConcertController·ReleaseController에 PUT/GET(me)/DELETE 별점 엔드포인트를 붙인다. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Concert/ReleaseService가 RatingService 집계를 조회해 상세·목록 응답에 averageRating, ratingCount 필드를 채운다. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
- 100자 초과 라인 정리 - rating.exception.UnauthorizedException 중복 제거, concert 것 재사용 - EMPTY_RATING_SUMMARY 중복 제거, RatingSummary.empty() 팩토리로 통합 - SecurityConfig에 GET .../rating/me 인증 carve-out 추가 Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
FE에서 공연 상태가 ENDED일 때만 별점 입력 UI를 노출하도록 정책을 변경함에 따라, 서버 측에서도 concert.status가 ENDED가 아니면 별점 등록·수정을 거부하도록 검증을 추가했다. release 별점은 정책 변경 대상이 아니므로 기존과 동일하게 상태 검증 없이 항상 허용한다. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

Make the first-time rating write atomic.
When no rating exists, RatingService.upsert performs a lookup and then an insert. Concurrent PUT requests for the same user and target can both observe no row. The rating unique constraint then rejects one insert. GlobalExceptionHandler maps the unhandled exception to HTTP 500 (INTERNAL_ERROR), so one request fails instead of returning 200. A retry after the winning transaction commits can succeed, but the first request still fails.
Use PostgreSQL INSERT ... ON CONFLICT (user_id, target_type, target_id) DO UPDATE, or an equivalent atomic repository operation.

score 범위 검증(0.5~5.0)이 서비스 계층에서 빠져있어 컨트롤러 우회 시 잘못된 값이 저장될 수 있는 문제와, 조회 후 삽입 방식의 upsert가 동시 첫 등록 요청에서 유니크 제약 위반으로 500을 반환하던 레이스 컨디션을 DB 원자적 upsert(INSERT ... ON CONFLICT)로 해결했다. 아울러 rating 컨트롤러 테스트가 인증된 사용자 ID 전파를 검증하지 못하던 공백과 테스트 파일의 import 순서 컨벤션 위반도 함께 정리했다. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
GET /api/mentions/search가 permitAll 목록에 포함되어 인증 없이 호출 가능했다.
해당 API는 게시글 작성 시 멘션 자동완성 용도로 인증된 사용자만 사용해야 하므로,

Closes #125
변경 개요
공연·릴리즈 상세/목록에 별점 평가 기능을 추가한다. Rating 엔티티와 등록·조회·취소 API, 평균 별점·평가 개수 집계 필드를 공연·릴리즈 응답에 반영해 FE 별점 UI(프론트엔드 #163)의 실연동을 지원한다. 또한 FE 요청에 따라 공연 별점은
ENDED상태에서만 등록·수정할 수 있도록 서버 측 검증을 추가했다.변경사항

변경사항 요약
Rating 도메인(엔티티·리포지토리·서비스·DTO·예외) 신규 추가, 공연·릴리즈 컨트롤러에 별점 등록·조회·취소 API 3종 추가, 공연·릴리즈 상세/목록 응답에 평균 별점 필드 반영, 공연 별점에 ENDED 상태 검증 추가.
검토 결과
🟡 warning
rating/service/RatingService.java:upsert()가 "조회 후 없으면 insert" 방식이라, 같은 사용자가 같은 대상에 동시에 첫 별점을 등록하는 요청을 보내면user_id·target_type·target_id유니크 제약 위반(DataIntegrityViolationException)이 발생할 수 있음. 현재GlobalExceptionHandler에 해당 예외 전용 핸들러가 없어 catch-allException핸들러로 떨어져 일반 500 응답이 나감.→ 발생 빈도가 낮은 레이스 컨디션이라 이번 PR을 막을 정도는 아니지만, 후속 작업에서
DataIntegrityViolationException을 잡아 409/기존 값 업데이트로 처리하거나 DBON CONFLICT방식으로 전환하는 것을 검토 권장.🔵 suggestion
rating/service/RatingService.java:validateTarget()에서 CONCERT는findById로 엔티티 전체를 로드하지만 상태 필드만 필요함. 목록·상세 조회 경로가 아닌 단건 쓰기 경로라 성능상 문제는 없으나, 상태만 조회하는 프로젝션이 있다면 더 가벼움.문제로 볼 정도는 아니며, 전체적으로 배치 집계로 N+1을 피하고 도메인 검증을 서비스 계층에 적절히 분리한 구현입니다.
