feedback_rounds 테이블을 새로 만들고 open_feedbacks에 year 컬럼을 추가·category 컬럼을 삭제한다. OpenFeedback을 record로 전환하고 회차 자동 배정을 위한 FeedbackRound/FeedbackRoundOptions 도메인, Repository/Service 계층을 둔다.
GET /v1/feedbacks/{feedbackId}. Swagger 명세는 AppFeedbackApi 인터페이스에,
라우팅·바인딩은 AppFeedbackController에 둔다.
GET /v1/feedbacks. year/round 쿼리 파라미터로 필터링하고 PageParams로 페이지네이션한다.
POST /v1/feedbacks. 현재 접수 기간이 열려 있는 회차로 연도·회차를 자동 배정하고, 열려 있는 회차가 없으면 FEEDBACK_NOT_OPEN을 응답한다.
GET /v1/feedbacks/rounds. 목록 화면의 연도 드롭다운·회차 칩을 그리는 데 쓰는 연도 목록/회차 목록을 내려준다. year 생략 시 현재 연도 기준.

지금 다른 PR들과 flyway 번호가 겹치는데 머지할 때 신경써서 수정한 후에 머지해 주세요.
유효성 검사 부분에서는 반복되는 피드백을 주고 있는 거 같은데 피드백을 수용해서 다음 번에는 반영될 수 있게 노력해주시면 좋을 거 같습니다.

어디선 OpenFeedback으로 쓰고, 에러코드같이 접두사 붙이는 곳에서는 Feedback으로 쓰는데 이거 OpenFeedback을 Feedback으로 이름을 바꾸는 게 통일성 측면에서 좋을 거 같은데 어떻게 생각하시나요?

round에 대한 유효성 검사는 검색이라는 비즈니스 맥락과 관심사가 다르다고 생각합니다. 차라리 year과 round를 묶은 vo를 만들어서 거기 생성자나 정적 팩토리 메서드에서 유효성 검사를 진행해보시는 게 좋을 거 같아요

조회 메서드에 읽기 전용 트랜잭션을 선언하세요.
getById와 search에는 @Transactional(readOnly = true)가 없습니다. 두 메서드에 선언을 추가하세요. 변경되지 않은 getRoundOptions에도 같은 규칙이 적용됩니다. 경로 지침은 “조회 전용은 @Transactional(readOnly = true)”를 요구합니다.

조회 전용 Service 메서드에 읽기 전용 트랜잭션 경계를 추가하세요.
OpenFeedbackServiceImpl.getById, search, getRoundOptions는 조회 전용 메서드입니다. 클래스와 인터페이스에도 트랜잭션 선언이 없으므로 세 메서드가 Service 수준의 @Transactional(readOnly = true) 요구를 위반합니다. 이는 데이터 무결성 문제가 아니라 트랜잭션 경계 규칙 위반입니다.

#️⃣연관된 이슈
🎯 해결하려는 문제가 무엇인가요?
학생이 열린피드백 게시판에 질문을 등록하고, 회차별로 질문/답변 목록을 조회할 수 있는 학생 앱 API가 없다.
❓ 왜 해결해야 하나요?
Figma에 이미 화면(목록/상세/작성, 연도 드롭다운+회차 칩)이 나와 있고 프론트 개발이 이어질 예정이라, 그에 맞는 API가 먼저 필요하다.
⭐ 어떻게 해결했나요?
feedback_rounds테이블을 새로 추가해 관리자가 여는 접수 회차(연도+회차+오픈/마감 시각)를 관리한다. 회차는 연도별로 1차부터 다시 시작한다.open_feedbacks에year컬럼을 추가하고, Figma 작성 화면에 선택 UI가 없는category컬럼은 제거했다.OpenFeedback을record로 전환하고, 정적 팩토리로create()(신규 등록)/of()(DB 복원)를 분리했다.GET /v1/app/feedbacks(목록, year/round 필터+페이지네이션),GET /v1/app/feedbacks/{feedbackId}(상세),POST /v1/app/feedbacks(질문 등록, 현재 열린 회차 자동 배정),GET /v1/app/feedbacks/rounds(연도/회차 필터 옵션) 4개 엔드포인트를 추가했다.AppFeedbackApi인터페이스에 모으고(@Tag/@Operation/@ApiErrorCode/@ParameterObject),AppFeedbackController엔 라우팅·바인딩만 남겼다.🧩 이 PR의 한계 & 트레이드오프
feedback_rounds등록/수정)와 답변 등록 API는 이번 범위에 없다 — 별도 이슈로 분리한다. 즉 이 PR만으로는POST /v1/feedbacks를 실제로 호출하려면 DB에 회차 행을 직접 넣어야 한다.INVALID_FEEDBACK_ROUND는round <= 0인 형식 오류만 검증하고, "그 회차가 실제로 존재하는지"까지는 검증하지 않는다(존재하지 않으면 빈 목록 반환).⛓️ 기존 기능에 미치는 영향
open_feedbacks는 이미V3마이그레이션으로 머지돼 있어 그 파일은 손대지 않고V9에서ALTER TABLE로 이어서 변경했다(컬럼 추가/삭제).gradle :bootstrap:test(ArchUnit + Modulithverify()) 통과 확인.🔀 Edge Case & 실패 시나리오
POST /v1/feedbacks→FEEDBACK_NOT_OPEN(409).feedbackId상세 조회 →FEEDBACK_NOT_FOUND(404).BaseTimeEntity.createdAt(insertable=false, DBDEFAULT CURRENT_TIMESTAMP)은save()직후 자바 객체에 반영되지 않는다는 걸 확인해서, 등록 응답에 바로 필요한questionedAt은 별도 컬럼으로 두고 애플리케이션이 직접 채우도록 했다(로컬 DB로 등록 직후 값이 정상 반영되는 것까지 확인).📋 검토한 대안과 선택 이유
questioned_at을created_at재사용 대신 별도 컬럼으로 둔 이유:created_at은 DB가 기본값으로 채우는 컬럼이라save()직후 자바 객체엔 반영되지 않아, 등록 응답에서만 값이 비어 보이는 문제가 있었다.year/round/page/size를 전부 묶는 대신,year/round는 낱개@RequestParam으로 두고 페이지네이션만 공용PageParams로 묶었다(기존AdminFeeController패턴과 통일).OpenFeedbackServiceImpl의 조회 메서드 3개(getById/search/getRoundOptions)에@Transactional(readOnly = true)를 붙이지 않은 이유:coding-style.md2-9절 예시를 그대로 따라 처음엔 셋 다 붙였는데, 리뷰 과정에서 재검토했다.readOnly = true가 실제로 아끼는 건 커밋 시점 Hibernate dirty-checking(flush) 하나뿐이고, 그 대가로REQUIRED전파가 새 트랜잭션을 여는 SET/COMMIT 왕복 비용을 낸다(SELECT 1개짜리 메서드에 SET/COMMIT 문 6개가 따라붙는 걸 로컬 general log로 실측함, 기존 회비 도메인 작업 때 확인). 이 트레이드오프가 의미 있으려면 애초에 "이 메서드가 트랜잭션을 열어야 할 이유"가 있어야 하는데, 세 메서드 다 그 이유가 없었다.getById(): 엔티티 하나 읽고 그대로 반환 — dirty-checking으로 아낄 게 없다.getRoundOptions():findDistinctYears()/findRoundsByYear()두 조회가 같은 트랜잭션 스냅샷을 공유해야 할 비즈니스 요구가 없고(연도 목록과 회차 목록이 아주 근소하게 다른 시점 값이어도 문제 없음), 반환 타입도List<Integer>라 관리 대상 엔티티 자체가 없다.search(): 페이지당 최대 수십 건을 읽지만, "row가 많으면 readOnly=true가 이득"이라는 논리는 "트랜잭션을 이미 열기로 정한 상태에서 readOnly=false(커밋 시 dirty-check) vs readOnly=true(스킵)"를 비교할 때만 성립한다.search()는 리포지토리 호출이 하나뿐이라 애초에 트랜잭션을 열 이유(다른 조회와 스냅샷 공유, 여러 Service 조합)가 없다. 트랜잭션을 아예 안 열면 SET/COMMIT 왕복 비용과 dirty-checking 대상이 둘 다 사라지므로 — "안 열기"가 "열고 readOnly로 스킵하기"를 비용 면에서 완전히 포함(strictly dominate)한다. 즉 row 수가 20건이든 20,000건이든 결론이 바뀌지 않는, 트레이드오프 없는 선택이다.@Transactional을 안 붙여도 나중에 이 메서드를 트랜잭션 안에서 호출하는 상위 코드(UseCase 등)가 생기면 자동으로 그 트랜잭션에 합류한다.create()만@Transactional(readOnly 아님)을 유지한다.💬 리뷰 포인트
[r]FeedbackRoundRepository가 "연도 목록"/"회차 목록"을 따로 반환하고 Service에서 조합하는 구조가 맞는지[c]OpenFeedback을record(불변)로 만든 것 — 상태 전이 메서드가 없어서coding-style.md2-1절 기본 규칙을 그대로 따랐다[a]GET /v1/app/feedbacks/rounds와GET /v1/app/feedbacks/{feedbackId}경로가 겹치지 않는지(리터럴 vs 변수 경로 매칭 우선순위로 확인함)
