 # 할 일 및 이슈
 
 ## 단기 확인
+- `v1.4.13`부터 DB 실명도 `topics / topic_items / favorite_topics / topic_id` 기준으로 옮겼으므로, 기존 운영 DB에서 서버 재시작 후 자동 마이그레이션이 한 번만 자연스럽게 수행되는지 먼저 확인한다.
+- 백엔드 응답은 현재 `topicId / topicName`과 `gameId / gameName`을 함께 내려주고 있으므로, 다음 단계에서는 실제 프런트/관리자에서 더 이상 `gameId` fallback이 필요 없는 지점을 확인해 호환 키 제거 순서를 정한다.
+- 티어표 공개 목록, 관리자 전체 티어표 관리, 저장/요청 API는 `topicId`를 우선 받도록 바꿨으므로, 실제 브라우저에서 검색/저장/공유/관리자 필터가 모두 같은 파라미터 체계로 자연스럽게 이어지는지 한 번 더 QA한다.
+- `/api/topics`, `/api/admin/templates` alias를 연 뒤 프런트 호출도 새 경로로 옮겼으므로, 실제 브라우저에서 주제 목록/즐겨찾기/주제 상세/관리자 템플릿 관리가 모두 같은 세션으로 자연스럽게 동작하는지 한 번 더 QA한다.
+- 프런트 API 호출부는 `topic/template` 의미 이름으로 옮겼으므로, 다음 단계에서는 `api.js` 안의 레거시 alias를 얼마나 더 유지할지와 백엔드 API 경로를 실제로 바꿀지 범위를 정한다.
+- 관리자 템플릿/주제 화면과 홈·에디터·즐겨찾기에서 새 API 이름층으로 바뀐 뒤에도 저장, 즐겨찾기, 템플릿 생성, 아이템 정렬 흐름이 자연스러운지 한 번 더 QA한다.
 - `topicHub / topicId`를 기본 라우트 기준으로 세웠으므로, 기존 `/games/...` 북마크와 새 `/topics/...` 주소 양쪽에서 주제 상세와 에디터 진입이 모두 자연스럽게 이어지는지 한 번 더 QA한다.
 - 다음 단계에서는 `api.getGame`, `listGames`, `favoriteGame`처럼 남아 있는 프런트 API 이름을 어느 수준까지 `topic/template` 의미로 감쌀지 정리한다.
 - 경로 헬퍼를 사용자 주요 화면에 연결했으므로, 로그인 리다이렉트·공유 프리뷰·복사본 이동·주제 복귀 흐름이 실제 브라우저에서 모두 같은 주소 체계로 자연스럽게 이어지는지 한 번 더 QA한다.

+- DB 실명 변경 마지막 단계로 `games / game_items / favorite_games`를 `topics / topic_items / favorite_topics` 기준으로 자동 마이그레이션하도록 정리하고, `tierlists.game_id`, `template_requests.source_game_id/target_game_id`도 각각 `topic_id`, `source_topic_id/target_topic_id`로 옮기게 했다.
+- 백엔드 저장/조회 쿼리는 이제 새 topic 스키마를 기준으로 동작하고, 응답에는 `topicId / topicName`을 기본으로 내려주되 기존 프런트가 바로 깨지지 않도록 `gameId / gameName`도 잠시 함께 유지했다.
+- 티어표 공개 목록, 관리자 전체 티어표 관리, 티어표 저장/요청 API는 `topicId`를 우선 받도록 정리하고 기존 `gameId`는 호환 입력으로만 남겨, 외부 표면과 실제 저장 스키마가 한 단계 더 가까워지게 맞췄다.
+
+## 2026-04-02 v1.4.12
+- 백엔드에 `/api/topics`와 `/api/admin/templates` alias 경로를 추가하고, 주제/템플릿 응답도 `topic/topics`, `template/templates` 키를 함께 내려주도록 정리했다.
+- 프런트의 새 의미 이름은 이제 실제로도 `/api/topics`, `/api/admin/templates`를 타도록 연결해, 경로 이름과 호출 이름이 다시 어긋나지 않게 맞췄다.
+
+## 2026-04-02 v1.4.11
+- 프런트 API 이름층을 한 단계 더 정리해 `listTopics / getTopic / favoriteTopic`, `updateAdminTemplate*`, `searchPublicTierListsByTopic` 같은 의미 기반 이름을 추가하고 실제 호출부도 이 기준으로 옮겼다.
+- 백엔드 경로와 응답 구조는 그대로 유지한 채 프런트에서 읽는 이름만 먼저 바꿔, 다음 단계의 API/모델 리네이밍 부담을 더 줄였다.
+
 ## 2026-04-02 v1.4.10
 - 주제 상세 라우트 이름을 `topicHub`로, 기본 경로 파라미터를 `topicId`로 바꾸고 기존 `gameId` 주소는 alias로 유지했다.
 - 앱 셸, 주제 상세, 티어표 편집기는 이제 내부에서 `topicId`를 우선 읽고, 레거시 주소로 들어온 경우에만 `gameId` fallback을 쓰도록 정리했다.
