-## 즉시 확인 필요
-- 레거시 업로드 메타 백필은 가능해졌으므로, 필요하면 다음 단계에서 실제 파일 경로까지 `/uploads/assets/` 기준으로 재정렬하는 마이그레이션을 검토한다.
-- 관리자 기본 아이템 다중 업로드는 현재 파일명 기반 자동 라벨만 지원하므로, 필요하면 업로드 후 일괄 라벨 수정/정렬 UX를 추가 검토한다.
-- 사용자 커스텀 아이템 승격은 현재 수동 복제 방식이므로, 필요하면 중복 감지나 “비슷한 항목 추천” 같은 보조 UX를 검토한다.
-- 관리자 티어표 관리의 추가 아이템 승격은 현재 커스텀(origin=`custom`) 아이템 기준이므로, 필요하면 “기존 게임 아이템과 비교한 차집합” 기준으로 더 정교하게 확장할 수 있다.
-- 이미지 최적화 기록은 월별 조회/비우기까지 지원하므로, 운영 단계에서는 보관 기간 정책과 자동 아카이브 기준을 정한다.
-
-## 배포 전 작업
-- NAS 실제 도메인 기준으로 `VITE_API_ORIGIN`, `CORS_ORIGINS`, `SESSION_SECRET`, `SESSION_COOKIE_SECURE`, `TRUST_PROXY` 값을 설정한다.
-- MariaDB 접속 정보 `DB_HOST`, `DB_PORT`, `DB_USER`, `DB_PASSWORD`, `DB_NAME`를 설정한다.
-- HTTPS를 사용할 경우 `SESSION_COOKIE_SECURE=true`로 설정하고 리버스 프록시 헤더 전달을 확인한다.
-- `backend/uploads/`, `backend/.sessions/`, MariaDB 백업 정책을 정한다.
-- 로컬 docker compose와 NAS MariaDB 사이의 버전 차이가 크지 않도록 유지한다.
-
 ## 중기 개선
 - 관리자용 티어표 승인/숨김 처리, 아이템 정렬 UI를 추가한다.
-- 회원 검색/필터, 일괄 권한 변경 같은 관리 보조 기능을 추가한다.
+- 회원 일괄 작업(다중 선택, 일괄 비밀번호 초기화, 활동 저조 계정 정리) 같은 관리 보조 기능을 추가한다.
 - 티어 행 프리셋 저장, 색상 관리, 행 복제 같은 고급 편집 기능을 추가한다.
+- 로그인/회원가입/관리자 비밀번호 초기화에 요청 횟수 제한을 추가한다.
+- 업로드 파일은 MIME 타입뿐 아니라 파일 시그니처 기반 검증까지 확장한다.
+- production에서 SESSION_SECRET 누락 시 서버가 부팅되지 않도록 강제한다.
+- helmet 기반 보안 헤더와 업로드 정적 응답 헤더를 정리한다.

 # 업데이트 로그
 
+## 2026-04-01 v1.3.25
+- todo 문서에서는 운영 정책/배포 체크 성격 항목을 우선 제거하고, 제품/보안 후속 작업 중심으로 다시 정리함.
+- 관리자 게임 관리는 우측 셀렉트 박스 대신 검색 가능한 리스트와 최신순/오래된순 정렬로 바꿔, 게임 수가 많아져도 실제로 선택 가능한 구조로 개선함.
+- 로그인과 회원가입은 기존 세션을 그대로 덮어쓰지 않고 세션을 재생성한 뒤 사용자 정보를 저장하도록 바꿔, 세션 고정 공격 방어를 보강함.
+
+## 2026-04-01 v1.3.24
+- 게임 선택 후 보이는 공개 티어표 목록 그리드도 auto-fit 최대폭 방식 대신 4/3/2/1열 고정 반응형 규칙으로 바꿔, 넓은 화면에서 카드 한 장이 애매하게 다음 줄로 넘어가며 공백이 크게 남던 문제를 줄임.

+## 2026-04-01 v1.3.22
+- 내 티어표 카드는 게임 목록과 같은 상단 히어로/패널 문법으로 다시 맞추고, 깨진 썸네일은 alt 텍스트가 카드 폭을 밀지 않도록 플레이스홀더로 즉시 대체해 카드 수와 헤더 폭이 흔들리지 않게 보정함.
+- 오른쪽 사이드 광고 프레임은 별도 보더·패딩·배경을 제거해, 광고 자체가 가진 각진 형태와 색이 그대로 보이도록 더 담백하게 정리함.
+
+## 2026-04-01 v1.3.21
+- 내 티어표 카드는 게임 목록 화면과 같은 카드 폭/헤더/메타 배치 문법으로 맞춰, 화면 간 카드 크기와 정보 정렬이 더 통일된 인상으로 보이도록 정리함.
+
+## 2026-04-01 v1.3.20
+- 내 티어표 카드 그리드는 카드 최대폭 우선 규칙 대신 더 촘촘한 auto-fill 기준으로 조정해, 넓은 화면에서도 한 줄에 더 많은 카드가 자연스럽게 배치되도록 보정함.
+
+## 2026-04-01 v1.3.19
+- 관리자 Image Optimization 기간 선택은 연도/월을 가로로 나란히 두고, 연도를 고르기 전에는 월 셀렉트를 숨겨 비어 있는 박스처럼 보이던 상태를 없앰.
+- 전체 초기화 버튼도 실제 월이 선택된 경우에만 보이도록 정리해, 사이드바 상단 필터 줄이 더 단정하게 보이도록 보정함.
+
+## 2026-04-01 v1.3.18
+- 커스텀 아이템 기본 이름은 파일명 전체를 그대로 쓰지 않고 확장자 제거·공백 정리·60자 제한을 먼저 적용하도록 바꿔, 템플릿 요청 전에 커스텀 업로드가 길이 제한으로 실패하던 흐름을 줄임.
+- 템플릿 요청 실패 안내는 커스텀 이미지 업로드 실패와 일반 bad request를 구분해, 사용자가 제목/설명/아이템 이름 길이 제한 문제를 더 쉽게 파악할 수 있게 보강함.
+- 관리자 Image Optimization 월 필터는 기본 month input 대신 연도/월 셀렉트와 전체 초기화 버튼으로 바꿔, 기간 선택을 더 직관적으로 조작할 수 있게 정리함.
+
+## 2026-04-01 v1.3.17
+- 티어 에디터 열 헤더 입력창과 행 라벨은 좌우 패딩을 대칭으로 다시 잡아, 드래그 핸들과 삭제 아이콘이 있어도 제목이 한쪽으로 쏠려 보이지 않도록 보정함.
+- 열 삭제도 이제 행 삭제와 같은 확인 모달을 거쳐 진행되도록 바꿔, 실수로 즉시 제거되던 문제를 막음.
+- 내보내기 보드는 여전히 960px 고정 폭이라 열 수가 늘수록 각 칸 폭이 줄어드는 구조라는 점을 기준으로 정리했고, 현재 보정은 헤더 정렬 문제를 우선 해결하는 쪽에 맞춤.
+
+## 2026-04-01 v1.3.16
+- 티어 에디터의 행 삭제와 열 삭제는 다시 작은 X 아이콘 액션으로 정리해, 행/열 이름 주변의 반복 텍스트 때문에 보드가 답답해 보이던 문제를 줄임.
+- 열 헤더 편집 영역은 입력창 오른쪽에 아이콘 삭제만 남기고, 행 라벨도 상단 우측의 작은 제거 버튼으로 맞춰 더 압축된 편집 밀도를 유지하도록 조정함.
+- 저장 이미지에서 열 제목이 살짝 위로 떠 보이던 문제는 내보내기 헤더의 비대칭 패딩을 제거하고 flex 중앙 정렬로 바꿔, 시각적으로 정확한 중앙에 오도록 보정함.
+
+## 2026-04-01 v1.3.15
+- 티어 에디터의 열 이름은 각 행 안에서 반복 렌더링되지 않도록 공통 상단 헤더로 분리해, 행 제목과 같은 구조로 더 또렷하게 구분되도록 수정함.
+- 행 추가/열 추가 액션은 새 SVG 아이콘 버튼으로 압축해, 텍스트 때문에 보드 상단 툴바 높이가 과하게 커지던 문제를 정리함.
+- 미리보기와 삭제 모달 문구도 행/열 기준으로 함께 정리해, 전체 티어 에디터 흐름을 더 일관된 용어와 레이아웃으로 다듬음.
+
+## 2026-04-01 v1.3.14
+- 티어 에디터를 단일 세로 랭크형에서 행/열 혼합 보드로 확장해, 공격·방어·지원 같은 가로 열을 추가하고 각 열 이름도 직접 입력할 수 있게 함.
+- 에디터 액션 문구를 `행 추가 / 열 추가` 기준으로 정리하고, 행 라벨 폭과 드래그 아이콘 위치를 다듬어 실제 사용 빈도에 맞는 더 압축된 보드 레이아웃으로 보정함.
+- 이름 오버레이 정렬과 저장용 미리보기 보드도 함께 손봐서, 이미지 다운로드 시 라벨 텍스트가 하단 중앙에 더 안정적으로 배치되도록 수정함.
+
+## 2026-04-01 v1.3.13
+- 템플릿 등록/업데이트 요청 모달은 이제 현재 티어표 제목·설명을 기본값으로 가져오고, 비어 있더라도 모달 안에서 바로 작성해 요청할 수 있도록 흐름을 단순화함.
+- 템플릿 요청 시 `내 티어 리스트에도 저장` 토글을 추가해, 요청 스냅샷만 관리자에게 전달할지 아니면 현재 양식도 내 티어표로 함께 저장할지 분리함.
+- 관리자 템플릿 요청 관리는 더 이상 원본 티어표 링크에 의존하지 않고, 요청 시점의 그룹/아이템/이름표시 상태를 그대로 담은 스냅샷 미리보기를 직접 열어 확인할 수 있게 확장함.
+
+## 2026-04-01 v1.3.12
+- 관리자 회원 관리 상단에 정렬 방향 선택을 추가해, 최근 활동순·가입순·작성 티어표순을 각각 오름차순/내림차순으로 다시 볼 수 있게 확장함.
+- 회원 정보 수정, 새 게임 생성, 비밀번호 초기화 모달은 Settings 톤 입력 스타일을 유지하면서 각 입력칸에 글자 수 피드백을 함께 보여주도록 정리함.
+- 로그인, 설정, 티어 에디터 제목·설명·요청 제목·요청 설명·티어 행 이름에도 최대 길이와 현재 입력 길이 안내를 붙여, 제출 전에 제한을 바로 인지할 수 있게 개선함.
+
+## 2026-04-01 v1.3.11
+- **회원 관리 편집 모달 전환**: 관리자 회원 카드를 읽기 전용 정보 카드로 바꾸고, `회원 정보 수정` 버튼으로 Settings 톤의 편집 모달에서 이메일/닉네임/운영자 권한을 저장하도록 재구성
+- **회원 검색/정렬 추가**: 회원 관리 상단에 이메일/닉네임 검색과 `최근 활동순`, `가입순`, `작성 티어표 많은 순` 정렬을 추가해 운영자가 원하는 기준으로 목록을 다시 볼 수 있도록 확장
+- **최고 관리자 보호 도입**: 가장 먼저 생성된 관리자 계정을 `최고 관리자`로 구분하고, 운영자는 최고 관리자 권한/아바타/비밀번호/삭제를 변경할 수 없도록 백엔드 보호 로직과 역할 메타데이터를 추가
+
+## 2026-04-01 v1.3.10
+- 게임 허브 공개 티어표 카드 그리드는 최소/최대 폭을 고정해, 목록이 1~2장뿐일 때도 카드가 화면 전체를 먹으며 과하게 커지지 않도록 보정함.
+- 티어표 행 삭제는 상단 아이콘 대신 우측 하단의 작은 텍스트 액션으로 바꿔, 랭크 카드 안에서 더 조용하고 정돈된 편집 흐름으로 정리함.
+- 공통 `SvgIcon` 컴포넌트를 추가하고 앱 셸, 홈 즐겨찾기, 관리자 회원 액션 같은 UI 아이콘은 `img` 대신 SVG 아이콘 컴포넌트로 렌더링하도록 전환함.
+
+## 2026-04-01 v1.3.9
+- 관리자 오른쪽 사이드의 Image Optimization 패널은 이제 기본 탭인 목록 관리에서만 노출되도록 줄여, 게임/아이템/티어표/회원 관리 화면에서는 실제 작업 패널에 더 집중할 수 있게 정리함.
+- 커스텀 아이템 상세의 '이미 사용 중인 게임' 목록에서는 개인 보드용 freeform 템플릿을 제외하고, 실제 템플릿에 연결된 게임만 보이도록 다듬음.
+- 티어표 행 삭제는 큰 버튼 대신 우측 상단의 작은 x 아이콘으로 바꾸고, 삭제 시 아이템이 풀 영역으로 돌아간다는 안내를 포함한 확인 모달을 거친 뒤 삭제되도록 개선함.
+
+## 2026-03-31 v1.3.8
+- 홈 화면 게임 즐겨찾기 버튼은 일반 문자 별 대신 'kid_star.svg' 아이콘을 사용하도록 바꿔, 기존 아이콘 시스템과 같은 문법으로 정리함.
+- 실제로 더 이상 참조되지 않는 예전 업로드 파일을 정리하는 레거시 업로드 클린업 스크립트를 추가하고, 루트/백엔드 실행 스크립트도 함께 연결함.
+- todo 문서도 이제 운영 반영 후 레거시 파일 정리 배치를 주기화하는 쪽으로 기준을 갱신함.
+
+## 2026-03-31 v1.3.7
+- 현재 참조 중인 레거시 업로드를 다시 최적화 자산 경로로 편입하고 DB 참조를 일괄 교체하는 1회 마이그레이션 스크립트를 추가함.
+- 아바타/썸네일/아이템 역할에 따라 기존 업로드를 512px 또는 1280px 규격으로 다시 정리해, 실제 참조 경로도 '/uploads/assets/' 체계에 점진적으로 수렴시킬 수 있게 함.
+- 루트와 백엔드에 레거시 마이그레이션 실행 스크립트를 연결하고, todo 문서도 다음 단계 기준으로 갱신함.
+
 ## 2026-03-31 v1.3.6
 - 현재 참조 중인 레거시 업로드 파일을 'image_assets' 메타에 안전하게 편입하는 1회 백필 스크립트를 추가해, 과거 이미지도 최적화 대시보드와 같은 통계 체계 안에서 집계할 수 있게 함.
 - 루트와 백엔드에 백필 실행 스크립트를 연결해 운영 중 필요할 때 즉시 재실행할 수 있도록 정리함.
