Explanation
Issue
#2479is active and directly linked. The reviewed code supports the main requirements:DeptServicefilters lists bystudent_yearwith the required fallback,StudentServicevalidates DB-backed departments and year mappings, preserves an omitted major, permits department-only records, and separates graduation recalculation. V17 and the reported tests support the schema and behavior. The reviewable change summary does not show the required staging apply, verification, and rollback SQL. The requesteddocs/sql/academic-programpath also returned no tracked files. The PR description and previous assessment do not prove that current-head SQL content exists.

32-55: 🗄️ Data Integrity & Integration | 🔵 Trivial | ⚡ Quick winExercise the fresh V16-to-V17 migration path.
migrate()createsacademic_program_yearby running the V17 SQL before Flyway targets V17. Because V17 usesCREATE TABLE IF NOT EXISTS, Flyway does not create the table in this fixture. The current assertions cover the manually created schema and rerun behavior, but a DDL regression that only affects creation on an absent table can pass.Keep the existing pre-created-table scenario and add a separate fresh V16 fixture, such as a second MySQL container, that runs Flyway directly from V16 to V17 and asserts that

학적 저장과 졸업 계산 분리
학번별 학부와 전공 목록 지원
academic_program_year테이블을 추가해 학번별 선택 목록을 관리합니다.GET /depts/major에student_year를 전달하면 해당 학번의 목록을 반환합니다.학부 검증을 DB 기준으로 통일
StudentDepartmentenum 검증을 제거하고department에 등록된 학부인지 확인하도록 합니다.기존 학적 보존과 새 학부 지원
NULL을 그대로 보존합니다.테이블 구조 (ERD)
학번 연도 + 학부 ID + 전공 ID를 연결해 해당 학번이 선택할 수 있는 조합을 관리하며,major_id = NULL이면 학부만 연결합니다.department_id와major_id를 계속 참조하고, 적용 SQL도 기존 행을 수정하거나 삭제하지 않고 새 행만 추가하므로 기존 학생의 소속이 유지됩니다.erDiagram department ||..o{ major : "학부에 속한 전공" department o|..o{ students : "학생의 학부" major o|..o{ students : "학생의 전공" department ||..o{ academic_program_year : "학번별 학부 연결" major o|..o{ academic_program_year : "학번별 전공 연결" department { int id PK varchar name "학부명" } major { int id PK int department_id FK varchar name "전공명, NULL 가능" } students { int user_id PK varchar student_number "학번" int department_id FK "NULL 가능" int major_id FK "NULL 가능" } academic_program_year { int id PK "신규 테이블" varchar student_year "학번 앞 4자리" int department_id FK "필수" int major_id FK "NULL 가능" int major_key "자동 생성, 중복 방지용" }💬 참고 사항
다음 학년도와 신설 학부 추가 절차 — 2027학년도 예시
1. 해당 학년도 요람과 기존 데이터 대조
2. 새 학년도 데이터 준비
department, 필요한 전공은major에 추가하고 해당 연도의 전체 선택 목록을academic_program_year에 등록합니다.student_year = '2027'로 등록하며, 전공 없이 학부만 연결할 때는major_id = NULL을 사용합니다.major_key는 DB가 자동 계산하므로 입력하지 않습니다.3. 스테이지에서 적용과 호환성 검증
GET /depts/major?student_year=2027로 목록을 확인합니다. 프런트엔드는 학생의 학번 앞 네 자리를 전달하도록 연결합니다.4. 프로덕션 반영과 이후 관리
GET /depts/major?student_year=2026처럼 학번 연도를 전달해야 합니다.✅ 검증
