+## 2026-07-23 v1.11.3 — 구형 블록 에디터 파일을 제거한다
+
+Markdown-first 에디터가 현재 게시물 작성 흐름을 담당하고 있고, `AdminBlockEditor.vue`는 실제 코드에서 더 이상 참조되지 않는다. 이전 동작을 되돌리기 위한 맥락은 Git 이력과 문서에 남아 있으므로, 실행 경로에 연결되지 않은 큰 컴포넌트 파일을 계속 보관하기보다 제거해 관리자 에디터 구조를 단순하게 유지한다.
+
 ## 2026-07-22 v1.11.0 — v1.10 구간을 minor로 마감하고 패치 기준을 다시 잡는다
 
 v1.10.0부터 v1.10.88까지 이어진 보안·백업·미디어 카탈로그·검증 보강을 공개 기록 `v1.11`로 묶고 관리 버전을 `1.11.0`으로 올린다. 이후 일상 수정은 `1.11.1`부터 패치로 쌓아, minor 단위 공지와 개발 버전 번호를 다시 맞춘다.

+  - `pages/admin/settings/index.vue`: 설정 카드별 저장·상태·검증 로직을 카드 컴포넌트 또는 composable 단위로 정리.
+  - `components/content/ContentMarkdownRenderer.vue`: 파싱·블록 렌더링·라이브 편집 중개·라이트박스·광고 삽입 책임을 분리.
+  - `components/admin/AdminPostForm.vue`: 태그 입력, 대표 이미지 선택, 발행/초안 저장 상태, 우측 설정 패널 책임을 분리.
+  - `pages/admin/media/index.vue`: 미디어 목록, 폴더 트리, 상세 모달, 재생성 액션을 작은 단위로 분리.
+- 관리자 UI 공통 컴포넌트 정리.
+  - 모달 패널, 필터 팝오버, 행 메뉴, 페이지네이션 툴바의 radius·shadow·z-index·색상 규칙을 공통화.

+- 최근 브라우저 회귀 테스트 추가.
+  - 태그 추천 선택 후 다음 태그 후보가 포커스 해제 없이 유지되는지 확인.
+  - 관리자 미디어 대표 이미지/본문 이미지 탭 전환 중 역할 배지가 노출되지 않는지 확인.
+  - 단일 이미지 `{size=}` 너비가 사용자 뷰어와 라이브 모드에 동일하게 반영되는지 확인.
+- 미디어 카탈로그 전환 코드 수명 정리.
+  - 운영 `MEDIA_CATALOG_MODE=database` 안정화 후 `shadow`/`filesystem` 런타임 분기 축소 가능 여부 검토.
+  - fallback은 운영 안정성에 필요하므로 제거 전 reconcile·로그·테스트 기준을 먼저 정리.
+- 운영 의존성 보안 업데이트 검토.
+  - `sharp <0.35.0` audit 경고는 breaking change 가능성이 있어 별도 검증 브랜치에서 이미지 업로드·썸네일 생성·본문 이미지 백필까지 확인 후 업데이트.
+- 문서 구조 정리.
+  - `docs/update.md` 장기 누적 이력은 최신 작업 중심으로 유지하고 오래된 상세 이력은 역할에 맞게 분리하는 방안 검토.
