+# HOTFIX-002: Sprint 태스크 수/완료 수 파싱 보정
+
+## 목표
+프로젝트 상세 화면에서 Sprint 상태는 맞게 보이지만 `태스크 0개 / 완료 0개`로 표시되는 문제 수정
+
+## 태스크
+
+### TASK-044: Sprint task count 파싱 수정
+- `.plans/sprints/SPRINT-XXX.md`에서 실제 태스크 개수를 파싱
+- 지원 포맷:
+  - `TASK-001: 설명`
+  - `- TASK-001 설명`
+  - `- [ ] TASK-001 설명`
+  - `- [x] TASK-001 설명`
+- 중복 카운트 방지
+- heading/본문에 포함된 단순 문자열 오탐 방지
+
+### TASK-045: 완료 task count 계산 보정
+- 완료 태스크 수 계산 규칙 정의
+- 우선순위:
+  1. 체크박스 `[x]` / `[X]`
+  2. 명시 status (`done`, `completed`, `passed` 등 정해진 패턴)
+  3. Sprint 자체가 done이면, 태스크 status 정보가 없을 경우 전체 완료 처리 여부 검토
+- UI에 `총 태스크 수 / 완료 태스크 수` 정상 반영
+
+## 검증 기준
+- 프로젝트 상세 Sprint 섹션에서 `0개 / 0개` 고정 해소
+- 실제 Sprint 문서 기준으로 task total 표시
+- 완료 태스크 수가 포맷에 맞게 계산
+- 빌드/테스트 통과
+- 외부 URL QA 필수

+# HOTFIX-003: 자매 상세 프로필 헤더/개요 레이아웃 개선 + Activity 로그 정리
+
+## 목표
+자매 상세 페이지에서 프로필 사진이 너무 작고 개요 정보 우선순위가 어색한 문제, Activity 로그에 raw stderr가 그대로 노출되는 문제를 개선
+
+## 태스크
+
+### TASK-046: 자매 상세 프로필 헤더 확대
+- `/sisters/[name]` 상단 프로필 영역 재디자인
+- 프로필 사진 크기 확대 (최소 96px~128px 권장)
+- 이름 / 역할 / 상태 배지 / 핵심 메타를 프로필 헤더에 재배치
+- “프로필 페이지” 느낌이 나도록 상단 hero 영역 구성
+
+### TASK-047: 개요 레이아웃 우선순위 조정
+- 현재 시스템 카드/활동 로그/개요의 시각적 비중 재조정
+- 프로필 헤더 → 핵심 상태 요약 → 활동 로그 순으로 위계 정리
+- 시스템 정보 카드(UPTIME, CPU, MEM, DISK)는 유지하되 보조 정보로 배치
+- 모바일에서도 헤더/요약/로그 순서가 자연스럽게 보이도록 조정
+
+### TASK-048: Activity 로그 사용자 친화화
+- raw stderr / 내부 명령문 / `bash: ... command not found` 같은 내부 오류 문자열 직접 노출 금지
+- ActivityLog 저장 시 또는 렌더 시 필터링/정규화:
+  - 내부 stderr는 숨기거나
+  - 사람이 읽을 수 있는 문장으로 변환
+- 사용자용 feed에는 의미 있는 이벤트만 노출
+- 필요하면 내부 디버그 로그와 사용자 표시 로그를 분리
+
+## 검증 기준
+- 자매 상세 페이지 프로필 사진이 현재보다 명확히 크게 표시
+- 개요 탭 시각적 우선순위가 자연스러움
+- 모바일에서도 레이아웃 깨짐 없음
+- activity feed에 raw stderr 직접 노출 0건
+- npm run build 성공 + 테스트 통과
+- 외부 URL QA 필수

+# SPRINT-009: 관리자 단순화 + 프로젝트 진행률 정상화 + 프로필 사진 수정
+
+## 목표
+관리자 전용 서비스에 맞게 회원가입 제거, 프로젝트 진행률 계산 정상화, 자매 프로필 사진 표시 버그 수정
+
+## 태스크
+
+### TASK-032: 회원가입 제거
+- `/register` 페이지 제거
+- `POST /api/auth/register` 엔드포인트 제거 또는 비활성화
+- `INVITE_CODE` 환경변수 및 초대코드 기반 가입 로직 제거
+- 로그인 전용 플로우로 단순화
+- FE: 로그인 페이지에서 회원가입 링크 제거
+- UX: 비로그인 시 `/login`으로만 이동
+
+### TASK-033: 프로젝트 Sprint 동기화
+- 각 프로젝트 repo의 `.plans/sprints/` 디렉토리를 읽어 Sprint DB 레코드 생성/업데이트
+- Gitea API로 repo tree 조회 또는 raw 파일 fetch
+- 동기화 대상:
+  - `SPRINT-001.md` ~ `SPRINT-XXX.md`
+  - Sprint number, name, status(기본 pending) 추출
+- API:
+  - `POST /api/admin/projects/:id/sync-sprints`
+  - `POST /api/admin/projects/sync-all-sprints`
+- Gitea sync 시 Sprint 동기화도 함께 수행 가능하도록 확장
+
+### TASK-034: 프로젝트 진행률 계산 수정
+- 현재 “스프린트 없음” 문제 해결
+- 진행률 계산 방식:
+  - 기본: `완료 Sprint 수 / 전체 Sprint 수`
+  - 가능하면 `.qa/` 또는 상태 기반으로 `done/review/in_progress` 반영
+- 프로젝트 목록 페이지(`/projects`): 진행률 바/퍼센트 표시
+- 프로젝트 상세 페이지(`/projects/[id]`): Sprint 목록 + 상태 표시
+- “No sprint data” fallback 제거
+
+### TASK-035: 프로필 사진 버그 수정
+- 현재 아이콘 fallback만 보이는 문제 원인 파악
+- 점검 항목:
+  - avatar API 경로 연결 여부
+  - FE 이미지 src 설정
+  - 캐시(5분 TTL) fallback 지속 문제
+  - 실제 서버 파일 경로 (`~/.openclaw/avatar.png|jpg|webp`) 확인
+- 수정 목표:
+  - 실제 사진 있으면 항상 우선 표시
+  - 실패 시에만 SVG fallback
+- 반영 위치:
+  - 대시보드 자매 카드
+  - `/sisters`
+  - `/sisters/[name]`

+
+## 목표
+JWT 로그인 기반으로 완전히 정리하고, 불필요한 API Key/초대코드/죽은 코드를 제거
+
+## 태스크
+
+### TASK-036: 관리 페이지 API Key UI 제거
+- 관리자 페이지에서 API Key 입력 필드/상태 제거
+- adminFetch가 JWT만 사용하도록 FE 정리
+- AuthContext 기반 인증 상태만 사용
+- 관련 안내 문구/placeholder 제거
+
+### TASK-037: JWT 전용 FE 정리
+- 로그인/토큰 관리 흐름 단순화
+- CompositeGuard 하위호환 때문에 남긴 FE 분기 제거
+- refresh/login/logout 로직 정리
+- 불필요한 fallback 코드 제거
+- 에러 처리 UX 정리 (401 → 로그인 페이지 이동)
+
+### TASK-038: API Key 하위호환 제거 또는 축소
+- 백엔드에서 API Key 지원 범위를 정리
+- 원칙:
+  - 일반 웹 UI는 JWT만 사용
+  - 필요한 내부 자동화가 없다면 API Key 완전 제거
+- 제거 대상 후보:
+  - ApiKeyStrategy
+  - CompositeGuard
+  - ADMIN_API_KEYS env
+- 만약 완전 제거가 부담되면 “운영/내부 스크립트 전용 엔드포인트”만 남기고 UI 경로는 JWT 전용으로 제한
+
+### TASK-039: 죽은 코드/불필요 코드 청소
+- invite/register 관련 unused code 제거
+- API Key 관련 사용 안 하는 util 제거
+- old fallback 코드 정리
+- 문서 업데이트:
+  - `.plans/design/` 변경 필요 시 반영
+  - README / 환경변수 설명 업데이트
+- grep 기반 점검:

+
+## 목표

+
+## 태스크
+
+### TASK-040: Sprint status 동기화 수정
+- 현재 `Status: value` 단일 줄 파싱이 실제 `.plans/sprints/*.md` 포맷과 맞지 않는 문제 수정
+- 실제 Sprint 문서 포맷 조사 후 파싱 규칙 재정의
+- 우선순위:
+  1. 명시 메타 블록 / heading 기반 status 파싱
+  2. QA 결과 파일(`.qa/SPRINT-XXX-review-*.md`) 기반 완료 여부 보조 판정
+  3. 없으면 pending
+- 오탐 방지: 본문 전체 키워드 검색 금지
+
+### TASK-041: 프로젝트 진행률 계산 수정
+- Sprint status가 실제 반영되도록 프로젝트 진행률 계산 로직 수정
+- 표시 기준:
+  - `done` Sprint 수 / 전체 Sprint 수 → %
+  - 필요 시 `review`, `in_progress`는 별도 상태 태그 표시
+- `/projects` 목록: 퍼센트 + progress bar 정상 반영
+- `/projects/[id]` 상세: Sprint 상태 목록 정확 표시
+- “0%만 뜨는” 현상 해소
+
+### TASK-042: 프로필 사진 실제 노출 수정
+- avatar API 응답 200이어도 fallback만 보이는 원인 파악
+- 점검 항목:
+  - FE 이미지 src 연결 여부
+  - `onError`가 과도하게 fallback으로 전환되는지
+  - `next/image` / `img` 캐시 문제
+  - content-type/image 응답 정상 여부
+  - avatar cache miss 후 stale fallback 유지 여부
+- 실제 파일 경로 재확인:
+  - `~/.openclaw/avatar.png`
+  - `~/.openclaw/avatar.jpg`
+  - `~/.openclaw/avatar.webp`
+
+### TASK-043: 아바타 UI 일관화
+- 대시보드, `/sisters`, `/sisters/[name]`, `/admin` 전부 같은 Avatar 컴포넌트 사용
+- 실제 이미지 우선 렌더
