+# DB Table Catalog
+
+## Purpose
+
+이 문서는 `8081 / work-8081` 기준 현재 PostgreSQL 테이블 27개를 역할별로 분류한 운영 기준 문서다.
+
+핵심 원칙:
+
+- 테이블 수가 많다고 바로 줄이지 않는다.
+- 먼저 `유지 / 주의 / 원본·추적 / 정리 후보`로 나눈다.
+- 실제 운영 화면과 저장 흐름에 필요한 것은 유지한다.
+- 의미가 불분명하거나 중복 역할만 하는 것은 후보로 남겨두고, 실제 삭제는 별도 검증 후 진행한다.
+
+## Summary
+
+- 전체 테이블: `26`
+- 유지: `16`
+- 주의: `6`
+- 원본·추적: `4`
+- 정리 후보: `0`
+
+## 1. 유지
+
+현재 운영 화면, 인증, 이력, 적재 흐름에서 계속 필요하다.
+
+- `auth.users`
+- `auth.sessions`
+- `auth.login_audit_logs`
+- `public.members`
+- `public.member_versions`
+- `public.history_revisions`
+- `public.seat_maps`
+- `public.seat_slots`
+- `public.seat_positions`
+- `public.seat_assignment_versions`
+- `public.integration_import_batches`
+- `public.integration_projects`
+- `public.integration_work_logs`
+- `public.integration_work_log_segments`
+- `public.integration_vouchers`
+- `public.integration_binary_sources`
+
+설명:
+
+- `members`, `seat_*`는 조직현황/자리배치도 핵심
+- `member_versions`, `seat_assignment_versions`, `history_revisions`는 as-of 조회와 이력 비교 핵심
+- `integration_*` 표준화 결과는 프로젝트별 분석 / 팀·개인별 분석 핵심
+- `integration_binary_sources`는 사업관리대장 같은 바이너리 원본 보관용
+- `auth.*`는 로그인과 권한 운영 핵심
+
+## 2. 주의
+
+현재도 역할은 있지만, 실제 운영에서 얼마나 계속 필요한지 주기적으로 점검해야 한다.
+
+- `public.member_overrides`
+- `public.member_retirements`
+- `public.member_aliases`
+- `public.integration_project_aliases`
+- `public.integration_project_category_mappings`
+- `public.integration_project_pm_assignments`
+
+설명:
+
+- 이 테이블들은 핵심 마스터라기보다 “보정/매핑/예외 처리” 성격이 강하다.
+- 운영상 필요할 수 있지만, 남용되면 기준 데이터가 흐려진다.
+- 사용 규칙과 관리 책임을 분명히 해야 한다.
+
+## 3. 원본·추적
+
+원본 적재와 검증을 위해 필요하다. 직접 서비스 화면의 주 출력원이 아니라, 적재 근거와 추적용이다.
+
+- `public.integration_raw_organization_rows`
+- `public.integration_raw_mh_rows`
+- `public.integration_raw_mh_pm_rows`
+- `public.integration_raw_payment_rows`
+
+설명:
+
+- 원본 파일을 바로 표준화 테이블에만 넣으면, 나중에 적재 오류를 추적하기 어렵다.
+- raw row 보관은 import 검증과 재현성 측면에서 의미가 있다.
+- 단, 장기 보관 정책과 용량 관리는 별도 필요하다.
+
+## 4. 정리 후보
+
+현재 기준 정리 후보 테이블은 없다.
+
+## Domain Map
+
+### 인증
+
+- `auth.users`
+- `auth.sessions`
+- `auth.login_audit_logs`
+
+### 조직 / 구성원
+
+- `public.members`
+- `public.member_overrides`
+- `public.member_retirements`
+- `public.member_aliases`
+
+### 자리배치도
+
+- `public.seat_maps`
+- `public.seat_slots`
+- `public.seat_positions`
+
+### 이력
+
+- `public.history_revisions`
+- `public.member_versions`
+- `public.seat_assignment_versions`
+
+### integration 표준화
+
+- `public.integration_import_batches`
+- `public.integration_projects`
+- `public.integration_project_aliases`
+- `public.integration_project_category_mappings`
+- `public.integration_project_pm_assignments`
+- `public.integration_work_logs`
+- `public.integration_work_log_segments`
+- `public.integration_vouchers`
+- `public.integration_binary_sources`
+
+### integration raw
+
+- `public.integration_raw_organization_rows`
+- `public.integration_raw_mh_rows`
+- `public.integration_raw_mh_pm_rows`
+- `public.integration_raw_payment_rows`
+
+## Operational Guidance
+
+### 바로 줄이지 말아야 하는 것
+
+- `integration_raw_*`
+- `member_versions`
+- `seat_assignment_versions`
+- `auth.*`
+
+이건 지금 구조상 “많아 보여도 필요한 층”이다.
+
+### 먼저 점검할 것
+
+- `member_overrides`, `member_aliases`, `project_aliases`의 실제 운영 빈도
+- `seat_maps`의 과거 실험 도면 정리 기준
+
+### 정리 원칙
+
+1. 테이블을 없애기 전에 실제 읽는 API/화면/스크립트를 확인한다.
+2. 원본 추적용 테이블은 운영 출력용 테이블과 구분해서 판단한다.
+3. 테이블 삭제보다 먼저 “사용 안 함” 상태를 문서화한다.
+4. 삭제는 백업과 검증 절차가 준비된 뒤에만 한다.
+
+## Recommended Next Checks
+
+1. `seat_maps` 과거 DXF 시도본 정리 기준 수립
+2. `주의` 그룹 테이블의 입력/수정 주체 명확화
+3. `DB 상태` 화면에서 이 분류를 기준으로 계속 설명 유지

+- 이 디렉터리는 `frontend/apps/db-status` publish 결과물만 둔다.
+- backend `/admin/db-status`는 여기의 `index.html`만 서빙한다.
+- 수정은 직접 여기서 하지 말고 `./scripts/publish_db_status_app.sh`를 사용한다.
