PRD: AI UGC Platform 1 — 프로필 & 네비게이션
Executive Summary
UGC Platform Phase 1 (프로필 & 네비게이션) 구현 완료 — 하단 3탭 + MY 프로필 (편집/공유/3탭/랜딩 로직) + 타유저 프로필 + 콘텐츠 가시성 필터 API. 17 AC 중 15 fulfilled / 2 partially (Maestro 자동화 불가 AC-2.3, 7.4 — 수동 QA deferred). PRD amendment 4건 (DRIFT-01~04) 전부 반영. 2 PR 생성 (Backend #794, App #555).

Root Cause |
Resolution |
| 001 |
E2E 테스트가 nx testMatch 미매치로 실제 실행 안 됨 |
spec_ambiguity (contract §공통빌드품질 bullet 4 의 "실행" 요구 모호) |
Fix R2 — jest-e2e.json moduleNameMapper + project.json test-e2e target 추가 |
| 001 |
me-contents e2e cursor=anyjunk 가 @IsBase64() 에서 400 — 시나리오 논리 오류 |
spec_ambiguity |
Fix R2 — 유효 base64 aWdub3JlZA== 로 교체 |
| 002 |
generating-failed.screen.tsx:45 tag:'all' — Home route 타입 변경 후 TS2353 regression |
spec_ambiguity (completeness-003 grep scope 부족) |
Fix R1 — nested screen:"HomeTab", params:{tag:"all"} |
| 002 |
screen-params.ts::withGlobalScreenConfig 제네릭 incompat (nested path config) |
dependency |
Fix R1 — 제네릭 제약 PathConfigMap<object> 로 완화 |
| 003 |
SwipeFeed 양쪽 queryFn 무조건 fire (discriminated union variant 별 gate 부재) |
spec_ambiguity |
Fix R1 — enabled: isProfileVariant / !isProfileVariant 가드 |

Issue |
Resolution |
| 001 |
content.repository.ts:225 cursor $lt 사용 → CursorResponseDto 규약(extra item as cursor)과 불일치, page 2 마지막 항목 누락 |
inline $lte 1-char fix (commit 000fc8fd) |
Systemic Patterns
5건 식별 — 다음 스프린트 Contract 드래프팅 시 반영 필요:
Cursor $lt → $lte 규약 (frequency 2, correctness): Repository 커서 쿼리는 $lte 필수. Contract V-method 에 rg '_id:\\s*\\{\\s*\\$lt\\s*:' → 0 hit grep 추가.
Nx testMatch 누락 탐지 (frequency 1, completeness): 신규 e2e-spec.ts 추가 시 project.json + jest-e2e.json 검증 — nx test --listTests | grep e2e-spec 로 discovery 확인.
Route param 타입 변경 시 callsite 누락 (frequency 2, completeness): FE typecheck 결과를 grep -v '@wrtn/' 로 clean 측정. completeness-003 grep scope 를 src/ 전체로 widening.
Conditional query enabled gate 부재 (frequency 2, completeness): Discriminated union / parent-dependent query 는 반드시 enabled 옵션 필수. Contract completeness-002 에 명시.
Parent context 의존 payload 의 prop threading 누락 (frequency 1, completeness): Planner 가 Ground Rule 에서 "상위 컨텍스트 필요 여부" 명시 + Evaluator contract review 에서 Prop flow 수동 trace.

presentation/coming-soon/ — ComingSoonScreen (placeholder 3개 메뉴)
presentation/settings/ — 8 canonical 메뉴 + ComingSoonSettingsSection
app/navigation/root-tab-navigator.tsx — 3 탭 + testID (home-tab / explore-tab / my-tab)
shared/routes/route.types.ts::SwipeFeed — discriminated union (legacy | profile variant)

New API Endpoints (Backend)
GET /v2/me/profile — MY profile + auto-nickname lazy bootstrap + persona flag
PATCH /v2/me/profile — partial update (nickname / profileImageFileUuid / bio / link)
GET /v2/me/contents?visibility={public|private|liked}&cursor=&limit= — visibility filter
GET /v2/me/contents/counts — counts per visibility (landing tab 결정용)
GET /v2/users/:userId/profile — 404 gate + public projection (isPersona 필드 부재)
GET /v2/users/:userId/contents?cursor=&limit= — public contents only

Next Sprint Recommendation
--follow-up=ugc-platform-001 으로 ugc-platform-002 생성 권장 — UGC Platform Phase 2 (피드 인터랙션 & 페이백) 스프린트 예상. 본 스프린트의 follow-up 은 2건 partially_fulfilled (수동 QA) + 5건 Minor deferred 로 small~medium 규모.
Regression Guard 필수:
- 기존 22 flow + 신규 8 flow = 30 flow 전수 PASS 확인 (E2E 풀스위트 실행)
- SwipeFeed discriminated union legacy variant 경로 (filter-list-item, trending-filter-section-item, swipe-feed.yaml) 회귀 검증
- Visibility 필터 legacy 문서 ({isPublished: undefined} → $ne:true 매칭) 의 다음 스프린트 신규 쿼리 재활용 시 동일 규약 유지
