+
+## 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`

+
+### 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

+# 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

+# SPRINT-006: 버그 수정 + 인증 시스템
+
+## 목표
+기존 버그 3건 수정 + JWT 기반 관리자 인증 시스템 구축
+
+## 태스크
+
+### TASK-020: 버그 수정 3건
+**우선순위: 최우선 (인증 전환 전에 기존 기능 안정화)**
+
+#### BUG-1: 하네스 편집 저장 실패 (PUT /api/admin/harness/:name/:file)
+- 증상: API Key 입력해도 저장 실패
+- 원인 조사: CORS PUT 메서드, DTO validation, AdminService.updateHarnessFile() 로직 확인
+- FE 측: Authorization 헤더 전달, Content-Type, 에러 핸들링 확인
+
+#### BUG-2: 로그 뷰어 초기 로드 안 됨
+- 증상: /admin/logs 페이지 진입 시 로그가 비어있음 (수동 새로고침 필요)
+- 수정: 컴포넌트 마운트 시 자동 fetch (useEffect 초기 로드)
+- 자매/lines 기본값 설정 후 자동 조회
+
+#### BUG-3: /api/admin/costs/record/:name 작동 안 함
+- 증상: POST 요청 시 응답 없거나 에러
+- 원인 조사: SSH 연결, python3 의존성, main.json 경로, 파싱 로직 확인
+- python3 미설치 시 fallback (jq 또는 Node.js 스크립트)
+
+### TASK-021: JWT 인증 BE
+- User 테이블 추가 (Prisma 마이그레이션)
+  ```
+  model User {
+    id        Int      @id @default(autoincrement())
+    username  String   @unique
+    password  String   // bcrypt hash
+    role      String   @default("admin")
+    createdAt DateTime @default(now())
+    updatedAt DateTime @updatedAt
+  }
+  ```
+- 인증 API:
+  - `POST /api/auth/register` — 초대 코드 필수 (INVITE_CODE env), bcrypt hash
+  - `POST /api/auth/login` — JWT access token (15분) + refresh token (7일)
+  - `POST /api/auth/refresh` — refresh token으로 새 access token 발급
+  - `GET /api/auth/me` — 현재 사용자 정보
+- JWT_SECRET, INVITE_CODE 환경변수
+- Rate limiting: 로그인 엔드포인트 (5회/분)
+- 테스트: auth 관련 유닛 테스트
+
+### TASK-022: 로그인/회원가입 페이지 FE
+- `/login` 페이지: username + password + 로그인 버튼
+- `/register` 페이지: username + password + 초대 코드 + 가입 버튼
+- 디자인: DESIGN-SYSTEM.md v2 준수 (미니멀 터미널 UI)
+- 로그인 실패 시 에러 메시지 표시
+- 토큰 저장: localStorage (access) + httpOnly cookie 검토
+- 라우트 보호: 비로그인 시 `/login`으로 리다이렉트
+- AuthContext/AuthProvider 구현
+
+### TASK-023: API Key Guard → JWT Guard 전환
+- JwtGuard 생성 (passport-jwt)
+- 기존 ApiKeyGuard 유지 + JwtGuard 병행 (CompositeGuard: JWT 먼저 → API Key fallback)
+- 하위호환: API Key는 Sprint 008까지 유지, 이후 제거 예정
+- WebSocket 인증: Socket.IO handshake에 JWT 토큰 검증 추가
+- 모든 @UseGuards 교체 (ApiKeyGuard → CompositeGuard)
+
+## 의존성
+- TASK-020 먼저 완료 → TASK-021 → TASK-022 → TASK-023
+- TASK-022는 TASK-021 완료 필요 (API가 있어야 FE 연동)
+
+## 검증 기준
+- 버그 3건 모두 재현 → 수정 → 동작 확인
+- 회원가입(초대 코드) → 로그인 → JWT 발급 → 보호된 API 접근 성공
+- API Key로도 기존 방식 그대로 접근 가능 (하위호환)
+- WebSocket 연결 시 JWT 검증
+- npm run build 성공 + 테스트 통과

+
+## 태스크
+
+### TASK-024: Gitea 동기화 API
+- GiteaService 강화 (기존 optional 패턴 유지)
+- API 엔드포인트:
+  - `POST /api/admin/gitea/sync` — Gitea org의 전체 repo를 DB에 동기화
+  - `GET /api/projects` — DB에서 프로젝트 목록 (Gitea 데이터 포함)
+- 동기화 로직:
+  - Gitea API `/api/v1/orgs/hanarang/repos` 호출
+  - 각 repo → Project 테이블 upsert (giteaId, name, repoUrl, description)
+  - 마지막 동기화 시간 기록
+- 자동 동기화: EventsScheduler에서 5분마다 폴링 (선택)
+
+### TASK-025: Commit/Branch/PR 조회 API

+- 로딩: 스켈레톤 UI
+
+### TASK-027: 활동 로그 자동 기록
+- ActivityLog 모델 활용 (기존 테이블 사용)
+- 자동 기록 트리거:
+  - 자매 상태 변경 시 (online ↔ offline)
+  - Gitea 동기화 시 (새 repo/커밋 감지)
+  - 관리자 액션 시 (재시작, 하네스 편집, 설정 변경)
+- ActivityService에 `logActivity()` 메서드 추가 → 각 서비스에서 호출
+- WebSocket으로 실시간 푸시 (`activity:new` 이벤트 활용)
+- `/activities` 페이지: 실제 ActivityLog 데이터 표시 (하드코딩 제거)
+- 필터/검색/페이지네이션 실제 동작
+
+## 의존성
+- Sprint 006 완료 필요 (JWT 인증)
+- TASK-024 → TASK-025 (repo가 DB에 있어야 commit 조회 가능)

+
+### B1: JWT_SECRET fallback 'changeme' — 3곳 (Critical)
+- **파일:** auth.service.ts:85, auth.module.ts:22, events.gateway.ts:48
+- **문제:** JWT_SECRET 미설정 시 'changeme'로 토큰 서명 → 공격자가 유효한 JWT 위조 가능
+- **모순:** jwt.strategy.ts는 throw하는데 나머지는 fallback → 불일치
+- **수정:** 3곳 모두 `?? 'changeme'` 제거, ConfigService.getOrThrow 또는 throw 처리
+
+### B2: User.role 기본값 "admin" (Critical)
+- **파일:** prisma/schema.prisma
+- **문제:** 모든 가입자 자동 admin → 초대코드만 알면 SSH restart, 하네스 수정 등 전체 인프라 제어
+- **수정:** `@default("viewer")` + admin 승격 별도 로직 + AdminController에 RoleGuard 추가
+
+### B3: WebSocket JWT 실패 시 disconnect 안 함
+- **파일:** events.gateway.ts:52-53
+- **문제:** invalid token 시 연결 유지 → 미인증 실시간 데이터 수신
+- **수정:** catch 블록에서 `client.disconnect()` 호출
+
+### B4: `throw new Error` → HttpException
+- **파일:** auth.controller.ts:32
+- **문제:** refresh token 없을 때 `throw new Error` → 500 반환
+- **수정:** `throw new BadRequestException('Refresh token required')`
+
+### B5: register 엔드포인트 rate limit 없음
+- **파일:** auth.controller.ts:18-20
+- **문제:** 초대코드 brute-force 가능
+- **수정:** `@UseGuards(ThrottlerGuard) @Throttle({ default: { limit: 3, ttl: 60000 } })` 추가
+
+## Non-blocking 이슈 (7건)
