 # 의사결정 이력

+## 2026-04-02 v1.4.15
+- 실제 운영 DB에서 마지막 500 원인을 먼저 재현해본 결과, 스키마 설계보다 MariaDB의 `SHOW ... LIKE ?` 플레이스홀더 비호환과 부분 마이그레이션 상태 재진입 이슈가 핵심이었으므로, 이 단계에선 구조 변경보다 기동 안정성을 먼저 회복하는 편이 맞다고 판단했다.
+- 마이그레이션 로직은 “처음 실행”뿐 아니라 “반쯤 적용된 상태에서 다시 실행”도 견뎌야 하므로, 컬럼 존재 확인과 조건 분기를 모두 공용 `information_schema` 검사로 모으는 편이 더 안전하다고 정리했다.
+
+## 2026-04-02 v1.4.14
+- 기존 `/games` 주소 호환은 alias보다 redirect가 더 맞다고 판단했다. 이번 단계에선 주소는 유지하되 라우트 파라미터 의미는 항상 `topicId`로 정규화해 Vue Router 경고와 내부 분기를 함께 줄였다.
+- 운영 DB에 직접 `RENAME TABLE`과 컬럼 `CHANGE`를 거는 방식은 실제 환경에서 실패 여지가 커서, 마지막 스키마 전환도 새 topic 스키마를 먼저 만들고 기존 game 데이터를 복사하는 비파괴 마이그레이션이 더 안전하다고 정리했다.
+
+## 2026-04-02 v1.4.13
+- 사용자 표면과 API 이름층까지 `topic/template`로 옮긴 뒤에는, DB 스키마도 실제로 따라오게 해야 이후 유지보수 비용이 덜 쌓이므로 `games` 계열 실명을 `topics` 계열로 마이그레이션하는 편이 맞다고 판단했다.
+- 다만 한 번에 응답 키까지 완전히 끊으면 프런트와 관리자 흐름이 너무 크게 흔들릴 수 있으므로, 이번 단계에서는 실제 저장 스키마는 `topic`으로 옮기고 응답의 `gameId / gameName`은 호환 키로 잠시 함께 유지하는 점진 마감이 가장 안전하다고 정리했다.
+
+## 2026-04-02 v1.4.12
+- 프런트 이름만 바꾸는 단계가 끝난 뒤에는, 백엔드도 새 `/api/topics`, `/api/admin/templates` 경로를 열고 기존 `/games`는 호환용으로 남기는 점진 전환이 가장 안전하다고 판단했다.
+
 ## 2026-04-02 v1.4.11
 - 백엔드 `/api/games` 경로를 바로 바꾸기보다, 프런트 API 객체에서 먼저 `topic/template` 의미 이름을 제공하고 호출부를 옮기는 편이 위험이 훨씬 낮다고 판단했다.

 # 할 일 및 이슈

 ## 단기 확인
+- `v1.4.15`에서 `ensureData()`가 실제 운영 DB 설정으로 `ok`까지 통과한 것은 확인했으므로, 이제는 브라우저에서 `/api/auth/me`, `/api/auth/meta`, `/api/topics` 500이 실제로 사라졌는지와 기존 세션 로그인 흐름이 복구됐는지 한 번 더 QA한다.
+- `v1.4.14`부터는 DB 마이그레이션이 rename 대신 복사 기반으로 바뀌었으므로, 실제 운영 DB에서 서버 재시작 후 `topics` 계열 테이블과 `tierlists.topic_id`, `template_requests.source_topic_id/target_topic_id`가 기대대로 채워지는지 먼저 확인한다.
+- 레거시 `/games/...`와 `/editor/:gameId/...`는 redirect로 남겼으므로, 오래된 북마크 진입 후 주소가 `/topics/...`, `/editor/:topicId/...`로 자연스럽게 정규화되는지 한 번 더 QA한다.
+- `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.

+- `db_init_failed`의 직접 원인은 MariaDB에서 `SHOW TABLES LIKE ?`, `SHOW COLUMNS ... LIKE ?` 플레이스홀더를 허용하지 않던 부분이었고, 이를 `information_schema` 조회 기반으로 바꿔 실제 운영 DB에서도 `ensureData()`가 정상 통과되게 고쳤다.
+- 중간 마이그레이션 상태에서 `template_requests.target_topic_id`가 이미 생긴 DB는 중복 컬럼 추가로 다시 실패할 수 있었으므로, 해당 확인도 `columnExists()` 기준으로 바꿔 부분 적용된 DB까지 안전하게 다시 기동되게 정리했다.
+
+## 2026-04-02 v1.4.14
+- `/games/:gameId`, `/editor/:gameId/...` 레거시 주소는 Vue Router alias 대신 redirect로 정리해, `topicId` 기준 라우트와 섞일 때 뜨던 param mismatch 경고를 제거했다.
+- 운영 DB에서 바로 `RENAME/CHANGE`를 치던 초기 마이그레이션은 위험도가 높아, `topics / topic_items / favorite_topics / topic_id` 스키마를 안전하게 만들고 기존 `games` 계열 데이터를 복사해 오는 방식으로 바꿨다.
+- DB 초기화 실패 시 원인을 바로 확인할 수 있도록 백엔드에서 `db_init_failed` 응답 전에 실제 에러를 서버 로그에 남기도록 보강했다.
+

+- 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.
