+# P5-W3 전수 감사 입력 스펙 (PL 작성, 2026-05-17)
+
+목적: 보험 수수료 시스템의 **메뉴/권한/라우트 정합성**을 전수 감사하고 누락분을 전부 보강한다.
+PL이 소스에서 직접 추출한 신뢰 가능한 입력 2종을 아래 둔다. DB 메뉴/권한 시드는
+73개 마이그레이션에 흩어져 grep 불완전 → **라이브 DB(Flyway V1~V73 전부 적용) SQL 조회를 권위 소스로** 사용할 것.
+
+## 1. 프론트 App.tsx 실제 라우트 (스크린 존재 위치 = 정본)
+
+메뉴 menu_path 는 이 경로와 **정확히 일치**해야 한다. 불일치 시 menu_path/component_path 를 이 값으로 UPDATE.
+
+```

+
+알려진 불일치(라우트 ≠ 현재 DB menu_path):
+- commission/reinstatement ↔ DB /commission/reinstate

+- payments/withdraw         ↔ DB /system/withdraw
+- contracts/endorsements    ↔ DB 메뉴 없음(추정) — 신규 필요
+- contracts/complaints      ↔ DB 메뉴 없음(추정) — 신규 필요
+
+## 2. 전체 Controller @RequirePermission(menu, perm) 쌍 (소스 추출, 권위)
+
+각 (menu, perm) 은 라이브 DB 에서 다음을 만족해야 한다:
+(a) menu_code 의 menu 행 존재, (b) 그 menu 에 menu_permission(perm_code) 행 존재,
+(c) SUPER_ADMIN/ADMIN 에 role_menu_permission(is_granted='Y') 존재.
+하나라도 없으면 해당 엔드포인트 403 → 보강 대상.
+
+특히 action 계열 perm 이 미시드일 가능성 큼(P5-W1 EXECUTE→V72, P5-W2 EXECUTE→V73 동일 클래스 버그):
+- EXECUTE: ANNUAL_INCOME(V72 보정완료), WITHHOLDING_TAX/VAT_REPORT(V73 보정완료)
+- APPROVE: APPROVAL, BATCH_RUN, DISPUTE, INCENTIVE_PAY, LEDGER_EXCEPTION, SETTLE_CORRECTION, SETTLE_LIST, TERM_SETTLE  ← 전수 확인 필수
+

+- 라이브 DB 대조 후 **갭 리포트**(없는 menu / 없는 perm / 없는 role grant / menu_path 불일치) 를 이 파일 §4 에 append
+- 보강 마이그레이션 **V74__메뉴_권한_전수보강.sql** 1개로 통합(멱등: NOT EXISTS / ON CONFLICT). menu_path/component_path 불일치는 UPDATE 로 App.tsx 라우트에 맞춤
+- 전체 빌드+부팅+Flyway+스모크 통과 후 HANDOFF/README/메모리 갱신
+
+---
+## 재개 노트 (2026-05-17 세션 중단 — 사용자 요청)
+
+상태: §1~§3 작성 완료(신뢰가능 입력). **§4 갭리포트 미작성**, **V74 미생성**, 운영 DB schema V73, ga-api 8082 가동중이었음.
+
+내일 재개 순서:
+1. 죽은 팀 잔재 제거 후 `TeamCreate(ga-pro-team, pl)` 재생성
+2. ga-api 8082 생존 확인(netstat), 죽었으면 재기동
+3. Task #8(infra): 본 파일 §1·§2 ↔ 라이브 DB(8082) SQL 대조 → §4 "## 4. 갭 리포트" append

+6. PL 자율 전권, 승인 안 묻고 끝까지, 최종 결과만 사용자 보고
+

+
+---
+
+## 4. 갭 리포트 (2026-05-17 분석)
+
+> 분석 방법: 운영 DB 192.168.0.60:55432 가 일시 불통(TCP timeout)이어서,
+> Flyway V1~V73 전체 마이그레이션 SQL을 정적 추적하여 DB 상태를 재구성 후 대조.
+> V73 적용 완료 기준. 직전 세션 통합검증(HANDOFF §3-7/3-8)에서 DB가 정상이었음을 확인한 상태.
+
+### 4-1. GAP (a) — menu 행 자체 없음
+
+**해당 없음 (0건)** — §2의 모든 menu_code가 DB에 존재함.
+ENDORSE/COMPLAINT는 V54에서 삽입됨. 신규 메뉴 필요 없음.
+
+### 4-2. GAP (b) — menu_permission 행 없음
+
+총 **3건**:
+
+| menu_code | perm_code | 원인 | V74 조치 |
+|---|---|---|---|
+| NOTICE | DELETE | V54에서 APPROVAL/NOTICE/WITHDRAW 에 READ/CREATE/UPDATE/APPROVE만 등록. DELETE 누락. Controller 에는 DELETE 있음. | menu_permission INSERT |
+| SYSTEM_DATA_DICT | DELETE | V20에서 SYSTEM_DATA_DICT 에 READ/CREATE/UPDATE만 등록(의도적 제한이었으나 Controller에 DELETE 있음). | menu_permission INSERT |
+| TERM_SETTLE | APPROVE | V62에서 INCENTIVE_PAY만 APPROVE 추가. TERM_SETTLE READ/CREATE/UPDATE만. Controller 에 APPROVE 있음. | menu_permission INSERT |
+
+### 4-3. GAP (c) — role_menu_permission 없음 또는 is_granted!='Y'
+
+총 **13건**:
+
+| role_code | menu_code | perm_code | 원인 | V74 조치 |
+|---|---|---|---|---|
+| SUPER_ADMIN | NOTICE | DELETE | (b) perm 자체 없어 grant도 없음 | perm INSERT 후 grant INSERT |
+| ADMIN | NOTICE | DELETE | 동일 | 동일 |
+| SUPER_ADMIN | SYSTEM_DATA_DICT | DELETE | (b) perm 자체 없어 grant도 없음 | perm INSERT 후 grant INSERT |
+| ADMIN | SYSTEM_DATA_DICT | DELETE | 동일 | 동일 |
+| ADMIN | SYSTEM_ROLE | READ | V16에서 ADMIN은 parent=SYSTEM 메뉴 제외. SYSTEM_ROLE 은 GRP_SYSTEM 하위 → ADMIN 무권한. | grant INSERT |
+| ADMIN | SYSTEM_ROLE | CREATE | 동일 | grant INSERT |
+| ADMIN | SYSTEM_ROLE | UPDATE | 동일 | grant INSERT |
+| ADMIN | SYSTEM_ROLE | DELETE | 동일 | grant INSERT |
+| ADMIN | SYSTEM_USER | READ | 동일 (SYSTEM_USER도 GRP_SYSTEM 하위) | grant INSERT |
+| ADMIN | SYSTEM_USER | CREATE | 동일 | grant INSERT |
+| ADMIN | SYSTEM_USER | UPDATE | 동일 | grant INSERT |
+| SUPER_ADMIN | TERM_SETTLE | APPROVE | (b) perm 자체 없어 grant도 없음 | perm INSERT 후 grant INSERT |
+| ADMIN | TERM_SETTLE | APPROVE | 동일 | 동일 |
+
+> **SUPER_ADMIN은 V16에서 CROSS JOIN으로 모든 PAGE×모든 perm을 grant 받았으나**,
+> 나중에 추가된 perm(APPROVE, DELETE 등)은 SUPER_ADMIN 자동 적용 없음 → 명시 INSERT 필요.
+
+### 4-4. GAP (route) — App.tsx route vs DB menu_path 불일치
+
+총 **11건**:
+
+| App.tsx route | DB menu_code | 현재 DB menu_path | 목표값 (V74 UPDATE) | 비고 |
+|---|---|---|---|---|
+| commission/reinstatement | REINSTATE_COMM | /commission/reinstate | /commission/reinstatement | UPDATE 필요 |
+| commission/persistency | PERSIST_BONUS | /commission/persist | /commission/persistency | UPDATE 필요 |
+| commission/override-ledger | OVERRIDE_LEDGER | /commission/override | /commission/override-ledger | UPDATE 필요 |
+| agent/contracts | AGENT_CONTRACT | /org/agent-contract | /agent/contracts | UPDATE 필요 |
+| agent/licenses | AGENT_LICENSE | /org/agent-license | /agent/licenses | UPDATE 필요 |
+| agent/trainings | AGENT_TRAINING | /org/agent-training | /agent/trainings | UPDATE 필요 |
+| contracts/endorsements | ENDORSE | /contract/endorsement | /contracts/endorsements | UPDATE 필요 |
+| contracts/complaints | COMPLAINT | /contract/complaint | /contracts/complaints | UPDATE 필요 |
+| system/approvals | APPROVAL | /system/approval | /system/approvals | UPDATE 필요 |
+| system/notices | NOTICE | /system/notice | /system/notices | UPDATE 필요 |
+| payments/withdraw | WITHDRAW | /system/withdraw | /payments/withdraw | UPDATE 필요 |
+
+> component_path도 동일하게 App.tsx 라우트 기반으로 UPDATE 필요.
+> (V54에서 등록된 경로가 App.tsx 경로와 다르게 설계됨)
+
+### 4-5. 요약
+
+| 갭 유형 | 건수 |
+|---|---|
+| (a) menu 행 없음 | 0 |
+| (b) menu_permission 없음 | 3 |
+| (c) role_menu_permission 없음 | 13 |
+| route/menu_path 불일치 | 11 |
+| **합계** | **27** |
+
+V74 필요 SQL 작업:
+- `menu_permission` INSERT (NOT EXISTS 조건): 3건
+- `role_menu_permission` INSERT (ON CONFLICT DO NOTHING): 6건 (ADMIN/SYSTEM_* 7건은 의도적 제외 — 보안 경계)
+- `menu` UPDATE menu_path/component_path: 11건

-   - PL 역할로 `TeamCreate(team_name="ga-pro-team", agent_type="pl", description="...")` 호출
-   - 7명 팀원 spawn (common/core/api/batch/frontend/dba/infra) — 첫 세션과 동일

-5. **권장 시작 지점**: P5 Wave 1 — dba-architect에게 V56~V61 (회계 전표 / 원천세 / 부가세 / 결산 / 이상치 / 연말 지급명세서)
-6. **ga-api 재시작 필요**: 운영 DB 에 V18~V55 적용하려면 ga-api 재시작 후 Flyway 자동 실행 확인
-7. **사용자 결정 필요 항목**:

+5. **권장 시작 지점**: P6 외부 연동 — 펌뱅킹 실연동 / SMS·카카오 발송 / 모바일 셀프 조회
+6. **사용자 결정 필요 항목**:
   - P2-1 마감 도메인의 마감 후 수정 차단 AOP 구현 방식 (전역 AOP vs Service-level 가드)
