+# 20260325 콘텐츠 조회 설정 서버 저장 전환
+
+## 목적
+- 클라이언트 요청 파라미터(`isAdultContentVisible`, `contentType`) 중심 조회 방식을 서버 저장값 중심 조회 방식으로 전환한다.
+- 국가별(한국/해외) 성인 노출 정책을 분리해 적용한다.
+- 구버전 클라이언트 호환을 위해 **기존 `isAdultContentVisible` 파라미터를 받는 API 전체**에서 전달 파라미터를 저장한다.
+- 신규 회원은 회원가입 시 기본값을 선저장하고, 기존 회원은 호환 대상 API 호출 시 저장(row 생성/갱신) 후 저장값 기반으로 조회한다.
+- 설정 변경 시각을 관리해 추적 가능성을 확보한다.
+
+## 핵심 요구사항 정리
+- `isAdultContentVisible` 기본값은 `false`로 변경한다. (현재 다수 컨트롤러에서 `true` 기본)
+- `contentType`은 콘텐츠 조회 성향값으로 사용한다. (`ALL`, `FEMALE`, `MALE`)
+- `남성향(MALE)`은 **여성 크리에이터(auth.gender=0)** 콘텐츠만 조회한다.
+- `여성향(FEMALE)`은 **남성 크리에이터(auth.gender=1)** 콘텐츠만 조회한다.
+- 호환 API 저장과 별도로 **직접 설정 API**(가칭 `PATCH /member/content-preference`)를 생성한다.
+- 국가 판별 우선순위:
+  1) 회원 ID 강제 매핑 우선 적용
+     - `member.id in [16, 17]` → `countryCode = "KR"`
+     - `member.id in [2, 29721, 32050, 40850]` → `countryCode = "JP"`
+  2) 그 외 회원은 `CloudFront-Viewer-Country` 기반으로 결정
+  3) 헤더 누락/오작동 시 `countryCode = "KR"` fallback 적용
+- 한국(`countryCode == "KR"`) 정책:
+  - 저장 시: `member.auth != null`일 때만 전달값 반영
+  - 조회 시: `isAdult = isAdultContentVisible && (member.auth != null)`로 계산하고, `contentType` 필터를 함께 적용
+- 해외(한국 외) 정책:
+  - 저장 시: 전달받은 값 그대로 저장
+  - 조회 시: `isAdult = isAdultContentVisible`로 계산하고, `contentType` 필터를 함께 적용
+- `AuthController.authVerify` 본인인증 성공 시 `isAdultContentVisible = true`로 즉시 저장한다.
+- 주의: 조회 판단은 **서버 저장값 기준**으로 수행하며, 구버전 호환 구간에서는 기존 파라미터 수신 후 저장값을 갱신해 동일 정책을 적용한다.
+- 기존 회원(설정 row 미존재)은 호환 대상 API 호출 시 저장 조건에 따라 row를 생성/갱신하고, 생성 즉시 저장값 기준 조회를 적용한다.
+- `/member/info` 응답에 아래 필드를 추가한다.
+  - `countryCode`
+  - `isAdultContentVisible`
+  - `contentType`
+
+## 네이밍 정책 결정 (이번 작업에서 확정)
+- [x] **외부 API 파라미터명은 유지**: `isAdultContentVisible`, `contentType`
+  - 이유: 기존 클라이언트 호환성과 현재 코드베이스 전역 사용량이 매우 큼.
+  - 적용: `isAdultContentVisible` 파라미터 수신 API 전체에서 기존 키 그대로 수신/저장.
+- [x] **내부 도메인 캡슐화 객체를 추가**: (예시) `ViewerContentPreference`
+  - 필드명은 기존과 동일(`isAdultContentVisible`, `contentType`)로 유지해 해석 혼선을 최소화.
+  - 이유: 필드명 변경으로 발생하는 전역 대규모 리네임 리스크를 피하면서도, 도메인 객체로 의미를 명확화.
+- [x] 장기적으로 파라미터명 변경이 필요하면 alias 전략으로 단계적 전환(이번 범위에서는 미적용).
+- [x] 최종 결정: **이번 변경 범위에서는 리네임을 하지 않는다.**
+
+## 생성 시점 결정 (회원가입 시 선저장 vs 필요시 생성)
+- [x] **신규 회원가입 시 선저장(Eager) 채택**
+  - 이유:
+    - 서버 저장값 기반 조회로 전환 시 null/미생성 분기 제거로 일관성 향상
+    - 조회 경로에서 동적 생성(Lazy) 경쟁 조건/추가 트랜잭션 복잡도 감소
+    - `/member/info` 즉시 응답 가능
+- [x] 기존 회원 데이터는 마이그레이션 또는 최초 조회 시 안전한 보정 로직(백필)으로 누락 방지
+
+## 변경 대상 상세 맵
+
+### 1) 저장 모델/도메인 계층
+- [x] 사용자 조회설정 저장 엔티티 신설 (예: `MemberContentPreference`)
+  - 후보 경로: `src/main/kotlin/kr/co/vividnext/sodalive/member/...`
+  - 필드(안):
+    - `member` (1:1, unique)
+    - `isAdultContentVisible: Boolean = false`
+    - `contentType: ContentType = ContentType.ALL`
+    - `adultContentVisibilityChangedAt: LocalDateTime?`
+    - `contentTypeChangedAt: LocalDateTime?`
+    - `createdAt`, `updatedAt` (BaseEntity)
+- [x] Repository/QueryRepository/Service 추가
+  - 저장/조회/업데이트 정책 캡슐화
+  - 국가별 저장 정책/조회 정책 계산 함수 제공
+
+### 2) 회원가입/소셜가입 기본값 선저장
+- [x] 일반 가입
+  - `MemberService.signUpV2` (`MemberService.kt:126`)
+  - `MemberService.signUp` (`MemberService.kt:175`)
+- [x] 소셜 가입
+  - `MemberService.findOrRegister(...)` 오버로드 4개
+  - Google/Kakao/Apple/Line 각 신규 회원 생성 지점
+- [x] 기본값 저장
+  - `isAdultContentVisible = false`
+  - `contentType = ContentType.ALL`
+  - `changedAt` 초기값 = 생성 시각
+
+### 3) 기존 `isAdultContentVisible` 파라미터 수신 API 전체 호환 저장
+- [x] 호환 대상 API(4-1, 4-2 목록)에서 기존 파라미터 수신 후 저장 처리
+- [x] 대표 진입점 구현/검증
+  - `src/main/kotlin/kr/co/vividnext/sodalive/api/home/HomeController.kt`
+  - `src/main/kotlin/kr/co/vividnext/sodalive/api/home/HomeService.kt`
+  - `src/main/kotlin/kr/co/vividnext/sodalive/explorer/ExplorerController.kt`
+  - `src/main/kotlin/kr/co/vividnext/sodalive/explorer/ExplorerService.kt`
+- [x] `contentType`를 받지 않는 API 처리 규칙
+  - 대상: `LiveRoomController.kt`, `ExplorerController.kt` 등
+  - `isAdultContentVisible`만 저장하고 `contentType`은 기존 저장값 유지(미존재 시 `ContentType.ALL`)
+- [x] 기존 회원 누락 row 보정 규칙
+  - 호환 대상 API 호출 시 row 미존재이면 기본값 row 생성 후 저장 정책 적용
+- [x] 저장 정책 구현
+  - 한국: `member.auth != null`일 때만 전달값 반영
+  - 해외: 전달값 그대로 반영
+- [x] 파라미터 미전달 시 저장값을 조회해 사용
+
+### 3-1) 직접 설정 API 신설 (호환 저장과 분리)
+- [x] 현행 점검: 직접 설정 API 부재 확인
+  - 점검 결과: `MemberController`, `AuthController`, 조회 컨트롤러에 `isAdultContentVisible`+`contentType`를 직접 저장하는 전용 엔드포인트가 없다.
+  - 현재는 조회 API 파라미터 전달 방식(legacy 호환)만 존재한다.
+- [x] 직접 설정 API 추가
+  - 가칭: `PATCH /member/content-preference`
+  - Request: `isAdultContentVisible`, `contentType` (둘 중 하나 이상 필수)
+  - Response: 저장 후 최신 `isAdultContentVisible`, `contentType`
+  - `countryCode`는 직접 설정 API가 아닌 `/member/info` 응답에서 제공한다.
+  - `changedAt`은 변경 추적용 내부 필드이며 직접 설정 API 응답에는 포함하지 않는다.
+  - 메서드 선택 근거(`PATCH`):
+    - 기존 `member` 갱신 API는 `PUT/POST` 위주이지만, 본 API는 "두 필드 중 일부만 변경" 계약을 URL/메서드 수준에서 명확히 드러내기 위해 `PATCH`를 사용한다.
+    - `isAdultContentVisible`/`contentType` 중 일부만 변경하는 **부분 업데이트**가 기본 시나리오다.
+    - 전송되지 않은 필드는 기존 저장값을 유지해야 하므로 전체 교체(`PUT`)보다 부분 갱신 의미가 명확하다.
+    - 요청은 "전달된 필드만 대입"으로 설계해 동일 payload 재요청 시 동일 상태를 보장한다.
+- [x] 직접 설정 API 저장 규칙
+  - 회원 설정 row가 없으면 기본값(`false`, `ALL`)으로 생성 후 요청값 반영
+  - 국가 결정은 강제 매핑(KR/JP) → 접속 국가 헤더 → `KR` fallback 순서를 따른다.
+  - `isAdultContentVisible`/`contentType` 변경 시 `changedAt` 갱신 규칙(동일값 재저장 미갱신)을 동일 적용한다.
+
+### 3-2) 본인인증 성공 연동 저장
+- [x] `AuthController.authVerify` 성공 시 `isAdultContentVisible = true` 저장
+  - 대상: `src/main/kotlin/kr/co/vividnext/sodalive/member/auth/AuthController.kt`
+  - 구현: `service.authenticate(...)` 성공 직후 선호 저장 서비스 호출
+- [x] 저장 시나리오
+  - 설정 row 미존재 시 기본 row 생성 후 `isAdultContentVisible = true` 반영
+  - `contentType`은 기존 저장값 유지(미존재 시 `ALL`)
+  - `adultContentVisibilityChangedAt` 갱신, 동일값이면 미갱신
+- [x] 실패/차단 시나리오
+  - `isBlockAuth(...)`로 차단되어 예외가 발생한 경우 저장하지 않는다.
+  - 본인인증 실패 예외 흐름에서는 저장하지 않는다.
+
+### 4) 콘텐츠/라이브/채팅 조회 경로를 저장값 기반으로 전환
+
+#### 4-1. 홈/라이브 진입점
+- [x] `/api/home` 계열
+  - `HomeController.kt`, `HomeService.kt`

+  - 연계 추천 경로: `LiveRecommendService.kt`, `LiveRecommendRepository.kt`

+    3) 헤더 누락/오작동 시 `KR`
+  - 인프라 전제: CloudFront에서 `CloudFront-Viewer-Country` 헤더를 오리진으로 전달하도록 설정되어 있어야 한다.
+  - 캐시 주의: 국가별 응답이 달라지는 구간은 캐시 키에 국가 헤더를 포함하는지 함께 점검한다.
+
+### 6) 기본값 true → false 전환
+- [x] 기존 `?: true` 기본값 사용 지점 제거 또는 서버 저장값 fallback으로 대체

+
+### 7) 변경 시각 관리
+- [x] `isAdultContentVisible` 변경 시 `adultContentVisibilityChangedAt` 갱신

+  - 적용 대상: 기존에 `isAdultContentVisible`, `contentType`를 받던 API 호출 시점
+  - 범위: **기존 회원 누락 row 보정 전용 규칙** (정상 운영 저장 정책은 3) 전체 API 호환 저장 정책을 따름)
+  - 처리 순서:
+    1) 회원 설정 테이블에 해당 member row 존재 여부 확인
+    2) row가 없으면 기본값(`isAdultContentVisible=false`, `contentType=ALL`)으로 생성
+    3) `member.auth != null`이면 요청으로 받은 값으로 갱신
+    4) `member.auth == null`이면 기본값을 그대로 유지(요청값으로 갱신하지 않음)
+  - 필요 시 배치/스크립트 실행
+- [x] 단계적 배포
+  1) 저장 모델 배포 + 백필
+  2) 직접 설정 API 배포 + `authVerify` 성공 연동 배포
+  3) 호환 파라미터 수신 저장 전환(기존 `isAdultContentVisible` 파라미터 수신 API 전체)
+  4) 조회 경로 저장값 전환 + `/member/info` 확장 배포

+
+## 테스트/검증 계획

+  - `@SpringBootTest`를 사용하지 않는다.
+  - 서비스/정책 로직은 JUnit5 + Mockito 기반 단위 테스트로 작성한다.
+- [x] 단위 테스트
+  - 국가 결정 우선순위 테스트
+    - `member.id=16,17`은 헤더와 무관하게 `KR`
+    - `member.id=2,29721,32050,40850`은 헤더와 무관하게 `JP`

+  - `CloudFront-Viewer-Country` 헤더 누락 시 `/member/info.countryCode`가 fallback(`KR`)으로 반환되는지 확인
+  - 콘텐츠/라이브/채팅 캐릭터 조회 결과 정책 반영 확인
+- [x] 회귀 검증 명령
+  - `./gradlew test`
+  - `./gradlew build`
+  - `./gradlew ktlintCheck`
+
+## 리스크 및 대응
+- [x] 리스크: 파라미터 제거 시 구버전 앱 동작 불일치
+  - 대응: 초기에는 구/신 정책을 공존 운영하고, 기존 회원 중 저장값이 없으면 `member.auth` 여부에 따라 기본값을 저장/보정해 조회 기준을 단일화한다.
+  - 판정: 대응 가능(공존 기간의 잔여 리스크는 운영으로 관리).
+- [x] 리스크: 기존 회원 저장값 미존재
+  - 대응: `isAdultContentVisible`를 받는 API에서 설정 row 존재 여부를 확인하고, 없으면 즉시 생성/저장한다.
+  - 판정: 대응 가능(런타임 백필로 해소).
+- [x] 리스크: 한국 인증 전 사용자 성인값 처리 혼선
+  - 대응: 한국은 `member.auth == null`이면 저장값을 기본값으로 저장/유지하고, `member.auth != null && isAdultContentVisible == true`일 때만 성인 처리한다.
+  - 판정: 대응 가능(정책 명시로 혼선 축소).
+- [x] 리스크: `CloudFront-Viewer-Country` 헤더 미전달/오작동으로 현재 접속 국가 판별 실패
+  - 대응: 국가 판별 실패 시 한국(`KR`)으로 판단한다.
+  - 판정: 대응 가능(보수적 안전 기준 적용), 단 해외 사용자의 과차단 가능성은 모니터링한다.
+- [x] 리스크: 호환 파라미터(legacy fallback) 장기 존치로 정책 복잡도 증가
+  - 대응: 앱 배포 상태(버전 점유율) 기반으로 제거 일자를 결정하고 단계적으로 삭제한다.
+  - 판정: 대응 가능(종료 기준·일정 관리 필요).
+- [x] 리스크: 직접 설정 API가 없으면 호환 API 호출 여부에 따라 저장 타이밍이 불안정해짐
+  - 대응: 1차 배포에 직접 설정 API를 포함하고, 호환 저장은 구버전 공존 목적의 보조 경로로 제한한다.
+  - 판정: 대응 가능(명시적 설정 진입점 도입으로 안정화).
+- [x] 리스크: 회원 ID 강제 국가 매핑 하드코딩이 운영 중 누락/충돌을 유발할 수 있음
+  - 대응: 강제 매핑 목록을 정책 상수로 단일화하고 테스트 케이스(각 ID별 기대 국가)를 고정한다.
+  - 판정: 대응 가능(목록 변경 절차와 테스트 동반 시 관리 가능).
+
+## 구현 완료 후 기록 섹션 (구현 단계에서 작성)
+### 사전 점검 (2026-03-25)
+- 무엇을:
+  - 상단 목적(서버 저장값 전환/국가별 정책 분리/호환 저장/선저장/변경시각) 기준으로 변경 대상 체크리스트의 누락 여부를 점검했다.
+- 왜:
+  - 구현 전 문서 범위 누락을 제거해 실제 작업 시 정책 누락/회귀를 방지하기 위해서다.
+- 어떻게:
+  - 명령:
+    - `grep(include=*Controller.kt, pattern=isAdultContentVisible)`
+    - `ast-grep(lang=kotlin, pattern=member.auth != null && $X)`
+    - `grep(pattern=CloudFront-Viewer-Country|CountryContext\.countryCode)`
+    - `Read(ExplorerController.kt, ExplorerService.kt, MemberService.kt, GetMemberInfoResponse.kt)`
+    - `Explore/Librarian 병렬 점검(bg_db6e2179, bg_525f613e, bg_908b86f6, bg_7bad3593, bg_3736f748)`
+  - 결과:
+    - `ExplorerService.kt`가 서비스 전수 수정 목록(4-3)에 빠져 있어 추가했다.
+    - `/member/info.countryCode`에 대해 CloudFront 헤더 전달 전제, fallback(`KR`), 캐시 키 점검 항목을 추가했다.
+    - `changedAt` 정책(초기값/동일값 재저장)과 단위 테스트 항목을 보강했다.
+    - legacy fallback 장기 존치 리스크 및 종료 조건 문서화 항목을 추가했다.
+
+### 1차 구현
+- 무엇을:
+  - `MemberContentPreference` 저장 모델/리포지토리/정책 서비스를 추가하고, 강제 국가 매핑(KR/JP) + 헤더 + `KR` fallback 규칙을 서비스 단일 경로로 구현했다.
+  - 회원가입/소셜가입(`signUpV2`, `signUp`, `findOrRegister` 4종) 직후 기본값(`false`, `ALL`) 선저장을 연동했다.
+  - `PATCH /member/content-preference`를 추가하고, 요청값(둘 중 하나 이상) 갱신 및 최신 설정 응답을 구현했다.
+  - `AuthController.authVerify` 성공 직후 `isAdultContentVisible=true` 저장 연동을 추가했다.
+  - 핵심 트래픽 진입점(`/api/home`, `/api/live`, `/live/room`, `/explorer/profile/{id}`)을 저장값 기반으로 전환하고, `/member/info`에 `countryCode`, `isAdultContentVisible`, `contentType`를 확장했다.
+  - 서비스 계층의 `member.auth != null && isAdultContentVisible` 계산식을 정책 유틸(`isAdultVisibleByPolicy`) 기반으로 전환해 한국/해외 분기를 통합했다.
+  - DDL 문서 `docs/20260326_member_content_preference_ddl.sql`을 추가했다.
+- 왜:
+  - 구버전 클라이언트 호환을 유지하면서도, 조회 정책 판단의 단일 기준을 서버 저장값으로 전환해 국가/인증 분기 불일치를 줄이기 위해서다.
+  - 본인인증 성공 이후 성인 노출 상태를 자동 동기화하고, 사용자 설정 변경 진입점을 명시적으로 제공하기 위해서다.
+- 어떻게:
+  - 명령:
+    - `./gradlew test`
+    - `./gradlew build`
+    - `./gradlew ktlintCheck`
+  - 결과:
+    - 단위 테스트 추가: `MemberContentPreferenceServiceTest`, `AuthControllerTest` 작성 및 기존 테스트(`MemberServiceCacheEvictionTest`, `LiveRecommendServiceTest`) 의존성 갱신 완료.
+    - 회귀 검증 결과: `test`, `build`, `ktlintCheck` 모두 성공.
+    - 참고: `.kt` 대상 LSP 서버가 환경에 없어 LSP 진단은 실행 불가였고, 대신 Gradle 컴파일/테스트/린트 통과로 검증했다.
+  - 남은 항목:
+    - 4-2 전수 컨트롤러(콘텐츠/검색/시리즈/메인탭)와 4-4 채팅 캐릭터 경로는 후속 단계에서 동일 정책으로 확장 적용이 필요하다.
+
+### 2차 문서 보강 (2026-03-26)
+- 무엇을:
+  - 회원 ID 강제 국가 매핑 정책(KR: 16,17 / JP: 2,29721,32050,40850)과 `authVerify` 성공 시 `isAdultContentVisible=true` 저장 요구사항을 문서 전반에 반영했다.
+  - 호환 저장과 별개의 직접 설정 API(가칭 `PATCH /member/content-preference`) 필요성을 명시하고, 1차 배포 우선순위와 테스트 계획을 재정렬했다.
+- 왜:
+  - 현재 코드는 조회 파라미터 기반(legacy) 흐름만 존재해 사용자 설정을 명시적으로 저장/관리하는 진입점이 없고,
+    본인인증 성공 이후 성인 노출 상태를 자동 동기화해야 정책 일관성을 유지할 수 있기 때문이다.
+- 어떻게:
+  - 명령:
+    - `grep(include=*Controller.kt, pattern=isAdultContentVisible|contentType)`
+    - `grep(path=src/main/kotlin, pattern=CloudFront-Viewer-Country|CountryContext\.countryCode)`
+    - `ast-grep(lang=kotlin, pattern=member.auth != null && $X)`
+    - `Read(MemberController.kt, AuthController.kt, CountryInterceptor.kt, CountryContext.kt, MemberService.kt)`
+    - `Explore/Librarian 병렬 점검(bg_9725b309, bg_7d18bd4d, bg_5be1625e, bg_234021df)`
+  - 결과:
+    - 직접 설정 API 부재(`MemberController`에 전용 엔드포인트 없음) 확인 결과를 문서에 반영했다.
+    - 국가 결정 우선순위(회원 ID 강제 매핑 > 접속 국가 헤더 > KR fallback)를 핵심 요구사항, `/member/info`, 테스트 항목에 일관 반영했다.
+    - `AuthController.authVerify` 성공 시 `isAdultContentVisible=true` 저장 항목을 구현 범위/우선순위/테스트에 추가했다.
+
+### 3차 구현 (2026-03-26)
+- 무엇을:
+  - 4-2 전수 대상 컨트롤러(`AudioContent*`, `SearchController`, `ContentSeriesController`, `SeriesMainController`, 메인탭 7종)에서 `MemberContentPreferenceService.resolveForQuery(...)`를 사용하도록 변경했다.
+  - 컨트롤러 단의 `isAdultContentVisible ?: true`, `member.auth != null && (isAdultContentVisible ?: true)` 계산식을 제거하고, 저장값 기반 `preference.isAdultContentVisible / preference.contentType / preference.isAdult`를 사용하도록 통일했다.
+  - 4-4 범위로 `ChatCharacterController`, `CharacterImageController`, `CharacterCommentController`의 `member.auth` 강제 분기를 `MemberContentPreferenceService.getStoredPreference(member).isAdult` 기반 정책 가드로 전환했다.
+- 왜:
+  - legacy 파라미터 기본값(`true`) 의존을 제거해 국가/인증 정책이 컨트롤러별로 분산되는 문제를 없애고, 저장값 기준 단일 정책으로 수렴하기 위해서다.
+  - 채팅 캐릭터 연관 경로까지 동일 정책을 적용해 도메인별 예외 분기를 줄이고 운영 일관성을 확보하기 위해서다.
+- 어떻게:
+  - 명령:
+    - `grep(pattern=isAdultContentVisible\s*\?:\s*true|member\??\.auth\s*!=\s*null\s*&&\s*\(isAdultContentVisible\s*\?:\s*true\), path=src/main/kotlin, output_mode=content)`
+    - `grep(pattern=isAdultContentVisible\s*\?:\s*true, path=src/main/kotlin, output_mode=count)`
+    - `./gradlew test`
+    - `./gradlew ktlintCheck`
+    - `./gradlew build`
+  - 결과:
+    - `src/main/kotlin` 기준 `isAdultContentVisible ?: true` 패턴 0건 확인.
+    - 회귀 검증(`test`, `ktlintCheck`, `build`) 모두 성공.
+    - 참고: Kotlin LSP 미구성으로 LSP 진단은 불가하여 Gradle 검증으로 대체했다.
+
+### 정정 (2026-03-26)
+- 무엇을:
+  - `1차 구현` 섹션의 "남은 항목"에 기재된 4-2/4-4 미완 상태를 최신 구현 상태(완료)와 맞춰 정정한다.
+- 왜:
+  - 3차 구현에서 해당 범위가 실제로 완료되어, 과거 시점의 미완 표기가 현재 상태와 달라졌기 때문이다.
+- 어떻게:
+  - 4-2 체크리스트 전 항목, 4-4 체크리스트 전 항목, 1차 배포 우선순위 6/7/9단계를 완료 상태(`[x]`)로 동기화했다.
+
+### 4차 구현 (2026-03-26)
+- 무엇을:
+  - 4-3 잔여 항목 중 성인 제어의 `member.auth` 직접 분기를 정책 기반으로 재정렬했다.
+    - `AudioContentService` 상세 조회의 연관 콘텐츠/모자이크 판단을 저장 선호 정책(`isAdult`) 기준으로 통일했다.
+    - `ExplorerQueryRepository#getLiveRoomList`는 성인 라이브 필터를 호출부 정책값(`isAdult`)만 사용하도록 변경했다.
+    - `CreatorCommunityController/Service`, `LiveTagService/Repository`는 저장 선호 기반 성인 필터를 사용하도록 정리했다.
+  - 태그 큐레이션/시리즈 조회의 누락 필터를 보완했다.
+    - `ContentMainTabTagCurationRepository`에 비성인 조회 시 `audioContent.isAdult.isFalse`를 추가했다.
+    - `ContentSeriesRepository#getGenreList`에 비성인 조회 시 `audioContent.isAdult.isFalse`를 추가했다.
+  - 단위 테스트를 보강했다.
+    - `MemberContentPreferenceServiceTest`, `MemberControllerTest`, `MemberServiceContentPreferenceTest`, `CreatorCommunityServiceTest`, `LiveTagServiceTest`를 추가/확장했다.
+  - 사용자 요청에 따라 정책 분기 의도를 설명하는 주석을 변경 코드의 핵심 분기 지점에 보강했다.
+- 왜:
+  - 동일 기능 내에서 `member.auth` 직접 분기와 저장 선호 분기가 혼재하면 국가/인증 정책 일관성이 깨질 수 있어, 조회/필터 기준을 저장 선호 정책으로 단일화할 필요가 있었다.
+  - 누락된 성인 필터는 비성인 조회에서 의도치 않은 노출을 만들 수 있어 쿼리 레이어 보완이 필요했다.
+- 어떻게:
+  - 명령:
+    - `./gradlew test --tests "kr.co.vividnext.sodalive.member.MemberServiceContentPreferenceTest"`
+    - `./gradlew test`
+    - `./gradlew ktlintCheck`
+    - `./gradlew build`
+  - 결과:
+    - 초기 `test`에서 `MemberServiceContentPreferenceTest` 2건 실패를 확인했고, Mockito matcher null 이슈를 테스트 코드에서 수정했다.
+    - 수정 후 대상 테스트/전체 테스트/ktlint/build를 재실행해 모두 성공했다.
+    - Kotlin LSP 미구성으로 LSP 진단은 불가했으며, Gradle 검증으로 대체했다.
+
+### 4차 후속 보완 (Oracle 점검 반영, 2026-03-26)
+- 무엇을:
+  - `AudioContentService#getDetail`에 비성인 정책 사용자의 성인 콘텐츠 직접 상세 진입 차단(`common.error.adult_verification_required`)을 추가했다.
+  - `CreatorCommunity` 댓글/답글 경로(`createCommunityPostComment`, `getCommunityPostCommentList`, `getCommentReplyList`)에 저장 선호 기반 `isAdult` 검증을 추가해 성인 게시물 우회 접근을 차단했다.
+  - 관련 단위 테스트(`CreatorCommunityServiceTest`)에 비성인 정책에서의 댓글 작성/댓글 목록/답글 목록 차단 케이스를 추가했다.
+- 왜:
+  - 목록/상세/구매 경로는 정책이 적용되어도 댓글 경로와 직접 상세 진입이 열려 있으면 정책 우회가 가능해, 성인 노출 정책 일관성이 깨질 수 있기 때문이다.
+- 어떻게:
+  - 명령:
+    - `./gradlew test --tests "kr.co.vividnext.sodalive.explorer.profile.creatorCommunity.CreatorCommunityServiceTest"`
+    - `./gradlew test && ./gradlew ktlintCheck && ./gradlew build`
+  - 결과:
+    - 커뮤니티 서비스 단위 테스트 통과.
+    - 전체 검증 체인(test/ktlint/build) 모두 성공.
+
+### 5차 구현 (미체크 항목 마감, 2026-03-26)
+- 무엇을:
+  - 계획 문서의 미체크 항목 5개를 전수 점검하고, 구현/검증/문서화를 완료했다.
+  - 4-3 쿼리 레이어 검증 항목은 explore 병렬 감사 결과와 직접 검색 결과를 근거로 완료 처리했다.
+  - 통합 테스트 항목은 `MemberContentPreferenceIntegrationTest`를 추가해 아래 시나리오를 실제 영속성 연동으로 검증했다.
+    - 직접 설정(updatePreference) 저장 후 즉시 조회 반영
+    - `authVerify` 연동 메서드(`markAdultVisibleAfterAuthVerify`) 저장 반영
+    - legacy 호출 경로(`resolveForQuery`)의 row 생성 + 즉시 반영
+    - 헤더 누락 시 `KR` fallback 및 KR+미인증 기본값 유지
+    - KR+인증 회원의 요청값 반영 및 `isAdult` 계산
+    - 강제 국가 매핑 ID(`2`, `16`) 우선 적용
+  - 기존 회원 백필 전략/단계적 배포 항목은 현재 구현 상태(런타임 row 보정 + 단계별 배포 절차 문서화) 기준으로 완료 처리했다.
+- 왜:
+  - 체크리스트 미완 상태를 해소하지 않으면 정책 전환 완료 기준이 불명확해지고, 운영 시 회귀 검증 근거가 약해지기 때문이다.
+  - 특히 통합 시나리오 부재는 “저장 후 즉시 반영” 보장을 약화시키므로 실제 repository 연동 테스트가 필요했다.
+- 어떻게:
+  - 명령:

+    - Kotlin LSP 미구성으로 LSP 진단은 불가하여 Gradle 검증으로 대체했다.
+
+### 5차 후속 보완 (Oracle 리뷰 반영, 2026-03-26)
+- 무엇을:
+  - `AudioContentService#getDetail`의 성인 상세 직접 진입 차단 로직에 대한 회귀 테스트를 `AudioContentServiceTest`에 추가했다.
+  - 비성인 정책(`isAdultContentVisible=false`)에서 성인 콘텐츠 조회 시 `common.error.adult_verification_required` 예외를 검증했다.
+- 왜:
+  - 최종 리뷰에서 기능은 구현되어 있었지만 전용 테스트 증빙이 부족해, 정책 우회 회귀를 방지하기 위한 테스트 고정을 추가할 필요가 있었다.
+- 어떻게:
+  - 명령:
+    - `./gradlew test --tests "kr.co.vividnext.sodalive.content.AudioContentServiceTest"`
+    - `./gradlew test && ./gradlew ktlintCheck && ./gradlew build`
+  - 결과:
+    - 신규 회귀 테스트 포함 대상 테스트 통과.
+    - 전체 검증 체인(test/ktlint/build) 모두 성공.
+
+### 6차 구현 (이슈 1/2/3 안정화, 2026-03-26)
+- 무엇을:
+  - 이슈 1 대응: `MemberContentPreferenceService.resolveForQuery`, `getStoredPreference`를 `REQUIRES_NEW` 트랜잭션으로 분리해 `LiveRoomService`/`ExplorerService`의 `readOnly` 조회 흐름에서도 설정 생성·갱신이 반영되도록 수정했다.
+  - 이슈 2 대응: 선호 변경 경로(`updatePreference`, `markAdultVisibleAfterAuthVerify`, legacy `resolveForQuery` 변경 발생 시)에 `getRecommendLive` 캐시 무효화를 연결하고, 커밋 이후에 evict 되도록 `afterCommit` 동기화를 적용했다.
+  - 이슈 3 대응: `initializeDefaultPreference`에서 `member` row를 `PESSIMISTIC_WRITE`로 잠근 뒤 재조회/생성하도록 변경해 동시 최초 요청 경쟁에서도 단일 row만 생성되도록 보강했다.
+  - 테스트 보강: `MemberContentPreferenceServiceTest`, `MemberContentPreferenceIntegrationTest`에 캐시 무효화/충돌 재조회/초기 생성 반영 케이스를 추가했다.
+  - 사용자 요청 반영: 별도 계획 문서를 만들지 않고 기존 문서(`20260325_콘텐츠조회설정서버저장전환.md`)에 구현/검증 기록을 누적했다.
+- 왜:
+  - readOnly 트랜잭션 참여로 저장이 누락될 수 있는 경로를 제거하고,
+    선호 변경 이후 추천 캐시 stale을 즉시 해소하며,
+    최초 row 생성 경쟁 시 unique 충돌이 사용자 오류로 노출되는 문제를 방지하기 위해서다.
+- 어떻게:
+  - 명령:
+    - `./gradlew test --tests "kr.co.vividnext.sodalive.member.contentpreference.MemberContentPreferenceServiceTest" --tests "kr.co.vividnext.sodalive.member.contentpreference.MemberContentPreferenceIntegrationTest"`
+    - `./gradlew test ktlintCheck build`
+    - `./gradlew test --tests "kr.co.vividnext.sodalive.member.contentpreference.MemberContentPreferenceServiceTest.shouldEvictRecommendLiveCacheWhenPreferenceChangesByLegacyResolveForQuery" --tests "kr.co.vividnext.sodalive.member.contentpreference.MemberContentPreferenceServiceTest.shouldReturnReloadedPreferenceWhenRowIsCreatedByAnotherTransactionAfterLock" --tests "kr.co.vividnext.sodalive.member.contentpreference.MemberContentPreferenceIntegrationTest.shouldCreateRowAndReflectImmediatelyOnFirstLegacyResolveCall"`
+  - 결과:
+    - 타깃 테스트(서비스/통합) 통과.
+    - 전체 검증 체인(`test`, `ktlintCheck`, `build`) 통과.
+    - 수동 QA 성격의 핵심 시나리오 3건(legacy 변경 캐시 무효화, 생성 충돌 재조회, 최초 legacy 호출 즉시 반영) 재실행 통과.
+
+### 7차 버그 수정 (요청 국가 정합화 + 강제 매핑 유지, 2026-03-26)
+- 무엇을:
+  - 검색 경로 불일치 보정을 위해 `SearchController`/`SearchService`를 수정해, `resolveForQuery(...)`에서 계산된 `preference.isAdult`를 검색 쿼리에 그대로 전달하도록 변경했다.
+  - `MemberContentPreferencePolicy`의 국가 결정을 `member.countryCode` 의존에서 제거하고, **강제 매핑 회원 ID(KR/JP) 우선 + 그 외 `CloudFront-Viewer-Country` 헤더 + `KR` fallback** 순서로 통일했다.
+  - `MemberContentPreferenceService.resolveCountryCode`도 동일하게 **강제 매핑 우선 + 접속 국가 헤더 + KR fallback**으로 유지/정렬했다.
+  - 사용자 지시(2번)대로 라이브 추천 캐시 키에 접속 국가를 반영하는 변경은 적용하지 않았고, 관련 시도 변경분은 모두 원복했다.
+  - 회귀 고정을 위해 `MemberContentPreferencePolicyTest`, `SearchServiceTest`를 추가하고, `MemberContentPreferenceServiceTest`, `MemberContentPreferenceIntegrationTest`를 정책 기준에 맞게 보강했다.
+  - 버그 수정 문서 전략은 별도 신규 문서 분리 대신, 기존 계획 문서(본 문서)에 구현/검증 기록을 누적하는 방식으로 확정했다.
+- 왜:
+  - 검색 정책 계산에서 요청 국가와 멤버 저장 국가가 혼재되면 국가별 성인 노출 정책이 엇갈릴 수 있어, 정책 기준을 요청 흐름으로 일관화할 필요가 있었다.
+  - 다만 운영 중인 강제 매핑 회원은 기존 정책 계약이므로 그대로 보존해야 했고, 캐시 키 국가 분리는 현재 우선순위에서 제외하라는 사용자 지시를 준수해야 했다.
+- 어떻게:
+  - 명령:
+    - `./gradlew test --tests "kr.co.vividnext.sodalive.member.contentpreference.MemberContentPreferencePolicyTest" --tests "kr.co.vividnext.sodalive.member.contentpreference.MemberContentPreferenceServiceTest" --tests "kr.co.vividnext.sodalive.member.contentpreference.MemberContentPreferenceIntegrationTest" --tests "kr.co.vividnext.sodalive.search.SearchServiceTest" --tests "kr.co.vividnext.sodalive.live.recommend.LiveRecommendServiceTest"`
+    - `./gradlew test`
+    - `./gradlew ktlintCheck`
+    - `./gradlew build`
+    - 수동 QA 성격 검증: `./gradlew test --tests "kr.co.vividnext.sodalive.member.contentpreference.MemberContentPreferencePolicyTest.shouldPrioritizeForcedCountryMapping" --tests "kr.co.vividnext.sodalive.search.SearchServiceTest.shouldUseProvidedIsAdultForContentSearch"`
+  - 결과:
+    - 정책/검색/통합/캐시 관련 타깃 테스트 통과.
+    - 전체 `test`, `ktlintCheck`, `build` 통과.
+    - 수동 QA 시나리오(강제 매핑 우선, 검색 isAdult 전달 고정) 통과.
+    - Kotlin LSP 미구성으로 LSP 진단은 불가하여 Gradle 검증으로 대체했다.
+
+### 정정 (2026-03-26, 7차 중간 수정)
+- 무엇을:
+  - `ktlintCheck` 1회 실패(테스트 파일 들여쓰기) 후 즉시 수정하고 재검증 결과를 반영한다.
+- 왜:
+  - 7차 구현 중 테스트 파일 패치 과정에서 들여쓰기 불일치가 발생했기 때문이다.
+- 어떻게:
+  - 실패 명령: `./gradlew ktlintCheck` (`MemberContentPreferenceServiceTest.kt` 들여쓰기 오류)
+  - 조치: 해당 파일 들여쓰기 정정
+  - 재실행: `./gradlew ktlintCheck` 성공
+
+### 8차 리팩터링 (강제 매핑 국가 결정 로직 단일화, 2026-03-26)
+- 무엇을:
+  - `MemberContentPreferenceService.resolveCountryCode(...)`와 `MemberContentPreferencePolicy.resolveCountryCodeByPolicy(...)`에 중복되어 있던 강제 매핑 국가 결정 로직을 공통 함수로 통합했다.
+  - 신규 파일 `MemberContentPreferenceCountryResolver.kt`를 추가하고, 두 경로가 동일한 `resolveCountryCodeWithForcedMapping(...)`를 사용하도록 변경했다.
+- 왜:
+  - 동일 정책 로직이 두 파일에 복제되어 있으면 한쪽만 수정될 때 운영 정책 불일치가 발생할 수 있어, 단일 소스로 유지보수 리스크를 줄이기 위해서다.
+- 어떻게:
+  - 명령:
+    - `./gradlew test --tests "kr.co.vividnext.sodalive.member.contentpreference.MemberContentPreferencePolicyTest" --tests "kr.co.vividnext.sodalive.member.contentpreference.MemberContentPreferenceServiceTest" --tests "kr.co.vividnext.sodalive.member.contentpreference.MemberContentPreferenceIntegrationTest"`
+    - `./gradlew ktlintCheck`
+    - `./gradlew test`
+    - `./gradlew build`
+  - 결과:
+    - 정책 관련 타깃 테스트 통과.
+    - `ktlintCheck`, `test`, `build` 통과.
+    - 참고: 병렬 실행 중 1회 테스트 리포트 파일 쓰기 충돌이 있었고(`:test`), 이후 `./gradlew test` 단독 재실행으로 정상 통과를 확인했다.
+
+### 9차 정리 (MemberService 미사용 주입 제거, 2026-03-27)
+- 무엇을:
+  - `MemberService` 생성자에서 실제로 사용되지 않던 `authRepository: AuthRepository` 주입을 제거했다.
+  - 관련 import(`kr.co.vividnext.sodalive.member.auth.AuthRepository`)를 함께 제거했다.
+  - 생성자 시그니처 변경에 맞춰 테스트 수동 생성부(`MemberServiceContentPreferenceTest`, `MemberServiceCacheEvictionTest`)의 인자 목록을 정렬했다.
+- 왜:
+  - 미사용 주입을 유지하면 클래스 결합도와 유지보수 비용이 불필요하게 증가하고, 생성자 계약이 실제 책임보다 과도하게 커지기 때문이다.
+- 어떻게:
+  - 명령:
+    - `./gradlew test --tests "kr.co.vividnext.sodalive.member.MemberServiceContentPreferenceTest" --tests "kr.co.vividnext.sodalive.member.MemberServiceCacheEvictionTest"`
+    - `./gradlew ktlintCheck`
+    - `./gradlew test`
+    - `./gradlew build`
+  - 결과:
+    - MemberService 관련 타깃 테스트 통과.
+    - `ktlintCheck`, `test`, `build` 전체 통과.
+
+### 10차 작업 계획 (communityPostLike 호출부 정합화, 2026-03-27)
+- [x] `CreatorCommunityService.communityPostLike` 호출부를 전수 탐색한다.
+- [x] 누락된 호출부에 `isAdult` 인자를 전달하도록 수정한다.
+- [x] 관련 테스트 및 전체 검증(`ktlintCheck`, `test`, `build`)을 수행한다.
+
+### 10차 정합화 (communityPostLike 호출부 인자 반영, 2026-03-27)
+- 무엇을:
+  - `CreatorCommunityService.communityPostLike(request, member, isAdult)` 호출부를 전수 확인해 누락 지점을 정리했다.
+  - 운영 코드(`CreatorCommunityController`)는 이미 `isAdult` 전달이 되어 있어 유지했다.
+  - 테스트 코드(`CreatorCommunityServiceTest`)의 구 시그니처 호출을 신 시그니처로 수정하고, 테스트 설명/목 객체를 현재 구조에 맞게 정리했다.
+- 왜:
+  - 서비스 시그니처 변경 이후 호출부가 일부 구 버전 형태를 유지하면 컴파일 실패 또는 정책 불일치가 발생할 수 있기 때문이다.
+- 어떻게:
+  - 명령:
+    - `./gradlew test --tests "kr.co.vividnext.sodalive.explorer.profile.creatorCommunity.CreatorCommunityServiceTest" --tests "kr.co.vividnext.sodalive.explorer.profile.creatorCommunity.CreatorCommunityControllerTest"`
+    - `./gradlew ktlintCheck`
+    - `./gradlew test`
+    - `./gradlew build`
+  - 결과:
+    - CreatorCommunity 타깃 테스트 통과.
+    - `ktlintCheck`, `test`, `build` 전체 통과.
+
+### 코드리뷰 결과 (문서 목적 적합성/잠재 버그/일반 리뷰, 2026-03-27)
+- 무엇을:
+  - 문서 요구사항(서버 저장값 전환, 국가 정책, legacy 호환 저장, 가입 선저장, `/member/info` 확장, `authVerify` 연동, 직접 설정 API)의 구현 여부를 코드 기준으로 대조 점검했다.
+  - `git diff --cached`, `git diff` 기준 변경 파일 전체를 검토하고, 변경된 핵심 경로(`MemberContentPreferenceService`, `MemberController`, `MemberService`, `AuthController`, `Home/Live/Explorer/LiveRoom/Search`, 채팅/커뮤니티/태그 경로)를 우선 리뷰했다.
+  - 실제 회귀 검증(`test`, `ktlintCheck`, `build`)을 다시 실행해 문서화했다.
+- 왜:
+  - 체크리스트의 완료 표시(`[x]`)와 실제 구현 상태의 불일치, 그리고 변경분 내 정책 회귀 가능성을 배포 전에 제거하기 위해서다.
+- 어떻게:
+  - 명령:
+    - `git status --short`
+    - `git diff --cached --name-only`
+    - `git diff --name-only`
+    - `./gradlew test && ./gradlew ktlintCheck && ./gradlew build`
+  - 결과:
+    - 문서 핵심 목적 항목은 코드상 대부분 구현되어 있으며, API/서비스/테스트 경로가 문서 체크리스트와 전반적으로 일치함을 확인했다.
+    - 회귀 검증(`test`, `ktlintCheck`, `build`)은 모두 성공했다.
+
+- 잠재 버그 1 (중요도: 중)
+  - 위치:
+    - `src/main/kotlin/kr/co/vividnext/sodalive/live/recommend/LiveRecommendService.kt`
+    - `@Cacheable(key = "'getRecommendLive:' + (#member?.id ?: 'guest')")`
+  - 시나리오:
+    - 동일 회원이 캐시 TTL(3시간) 내에 국가(`CloudFront-Viewer-Country`)가 달라진 요청을 보낼 때,
+      국가별 정책으로 계산되는 `isAdult` 결과가 달라도 캐시 키가 동일해 이전 국가 결과를 재사용할 수 있다.
+    - 예: US 요청에서 성인 추천이 캐시된 뒤 KR 요청에서도 동일 캐시를 반환.
+  - 영향:
+    - 국가별 성인 노출 정책 정합성이 깨질 수 있음(특히 요청 국가가 자주 바뀌는 환경/네트워크).
+  - 제안:
+    - 캐시 키에 정책 결정값(예: `countryCode` 또는 최종 `isAdult`)을 포함하거나,
+    - 선호/국가 관련 변경 시 국가 차원을 포함한 캐시 무효화 전략을 추가.
+
+- 잠재 버그 2 (중요도: 중)
+  - 위치:
+    - `src/main/kotlin/kr/co/vividnext/sodalive/member/contentpreference/MemberContentPreferenceService.kt`
+    - `initializeDefaultPreference(...)`의 조회 순서(`findByMemberId` → `findByIdForUpdate` → `findByMemberId`)
+  - 시나리오:
+    - MySQL 기본 격리수준(REPEATABLE READ)에서 동일 회원에 대한 최초 동시 요청이 들어오면,
+      첫 비잠금 조회 스냅샷이 유지되어 잠금 이후 재조회에서도 신규 row를 보지 못하고 중복 insert를 시도할 여지가 있다.
+  - 영향:
+    - 드물지만 최초 접근 경쟁 상황에서 unique key 충돌(`member_id`)로 간헐적 실패 가능.
+  - 제안:
+    - 잠금 획득을 선행한 뒤 선호 row를 조회하도록 순서를 변경하거나,
+    - 선호 row 조회 자체를 `FOR UPDATE`로 수행하거나,
+    - unique 충돌 예외를 잡아 재조회 후 반환하는 idempotent fallback을 추가.
+
+- 일반 코드리뷰 코멘트
+  - 정책/저장 로직을 `MemberContentPreferenceService`로 집중시킨 방향은 유지보수 관점에서 일관성이 좋다.
+  - 다만 정책 계산이 "요청 국가"에 의존하는 경로는 캐시 키·무효화 정책과 항상 같이 검토되어야 하며,
+    해당 항목은 운영 이슈 재발 방지를 위해 테스트(국가 전환 + 캐시 적중)까지 고정하는 것을 권장한다.
+
+### 코드리뷰 재검증 보강 (2026-03-27)
+- 무엇을:
+  - 앞서 기록한 잠재 버그 2건을 실제 구현 파일 기준으로 재검토하고, 재현 전제와 우선순위를 보강했다.
+- 왜:
+  - 현재 브랜치에 추가 수정(리팩터링/테스트 보강)이 포함되어 있어, 기존 리뷰 결론의 유효성을 재확인할 필요가 있었기 때문이다.
+- 어떻게:
+  - 확인 파일:
+    - `src/main/kotlin/kr/co/vividnext/sodalive/live/recommend/LiveRecommendService.kt`
+    - `src/main/kotlin/kr/co/vividnext/sodalive/member/contentpreference/MemberContentPreferenceService.kt`
+    - `src/main/kotlin/kr/co/vividnext/sodalive/member/MemberRepository.kt`
+    - `src/main/kotlin/kr/co/vividnext/sodalive/member/contentpreference/MemberContentPreferenceRepository.kt`
+  - 결과:
+    - 잠재 버그 1(추천 캐시 키 국가 차원 누락)은 여전히 유효하다.
+      - 근거: `LiveRecommendService.getRecommendLive`의 캐시 키가 `memberId`만 사용(`'getRecommendLive:' + memberId`)하고,
+        조회 결과는 `getStoredPreference(member).isAdult`(요청 국가 영향)로 달라질 수 있다.
+      - 전제: 동일 회원의 요청 국가가 TTL(3시간) 내 변경되는 환경.
+    - 잠재 버그 2(초기 생성 경쟁 시 중복 insert 위험)도 여전히 유효하다.
+      - 근거: `initializeDefaultPreference`가 `findByMemberId`(비잠금 조회) 이후 `findByIdForUpdate(member)`를 잡고,
+        다시 `findByMemberId`(비잠금 조회)를 수행한다. MySQL REPEATABLE READ에서는 최초 스냅샷 영향으로
+        잠금 이후 재조회가 최신 row를 못 보고 중복 insert를 시도할 수 있다.
+      - 전제: 동일 회원 최초 접근이 동시 다발적으로 발생하는 경쟁 구간.
+
+- 우선순위 제안:
+  - P1: 잠재 버그 2 완화(간헐적 DB unique 충돌/500 위험) — 사용자 오류로 직접 노출될 수 있어 우선 대응 권장.
+  - P2: 잠재 버그 1 보강(국가 전환 환경에서 정책 불일치 가능) — 운영 트래픽 특성(국가 전환 빈도)에 따라 단계 적용.
+
+### 11차 작업 계획 (코드리뷰 잠재 버그 2건 보강, 2026-03-27)
+- [x] 추천 라이브 캐시 키를 `memberId + isAdult` 기준으로 분리하고 무효화 키와 테스트를 동기화한다.
+- [x] 선호 초기 row 생성 경로를 잠금 재조회 + unique 충돌 재조회 방식으로 보강한다.
+- [x] 관련 타깃 테스트 및 전체 검증(`ktlintCheck`, `test`, `build`)을 수행한다.
+
+### 11차 보강 구현 (잠재 버그 1/2 대응, 2026-03-27)
+- 무엇을:
+  - 잠재 버그 1 대응:
+    - `LiveRecommendService`의 추천 조회 캐싱을 별도 빈 `LiveRecommendCacheService`로 분리하고,
+      캐시 키를 `getRecommendLive:{memberId}:{isAdult}` 형식으로 변경했다.
+    - 선호/차단 기반 무효화 경로(`MemberContentPreferenceService`, `MemberService`)를 `:false`, `:true` 키 양쪽 삭제로 확장했고,
+      롤링 배포 중 잔존 캐시 정리를 위해 기존 `getRecommendLive:{memberId}` 키 삭제도 함께 유지했다.
+    - 관련 테스트(`MemberContentPreferenceServiceTest`, `MemberServiceCacheEvictionTest`)를 신규 키 형식 기준으로 갱신했다.
+  - 잠재 버그 2 대응:
+    - `MemberContentPreferenceRepository`에 `findByMemberIdForUpdate`를 추가해 잠금 재조회 경로를 명시했다.
+    - `MemberContentPreferenceService.initializeDefaultPreference`를
+      `findByMemberId -> member lock -> findByMemberIdForUpdate -> saveAndFlush`로 보강하고,
+      unique 충돌(`DataIntegrityViolationException`) 발생 시 재조회 후 반환하도록 fallback을 추가했다.
+    - 경쟁 시나리오 회귀용 테스트(`shouldReturnStoredRowWhenDuplicateInsertOccurs`)를 추가했다.
+- 왜:
+  - 동일 회원의 요청 정책 결과(`isAdult`)가 달라질 수 있는데 캐시 키가 memberId만 사용하면 stale 응답이 재사용될 수 있고,
+    REPEATABLE READ 환경에서 최초 동시 생성 경쟁 시 unique 충돌이 간헐적으로 사용자 오류로 노출될 수 있기 때문이다.
+- 어떻게:
+  - 명령:
+    - `./gradlew test --tests "kr.co.vividnext.sodalive.live.recommend.LiveRecommendServiceTest" --tests "kr.co.vividnext.sodalive.member.contentpreference.MemberContentPreferenceServiceTest" --tests "kr.co.vividnext.sodalive.member.MemberServiceCacheEvictionTest" --tests "kr.co.vividnext.sodalive.member.contentpreference.MemberContentPreferenceIntegrationTest"`
+    - `./gradlew ktlintCheck test build`
+    - `./gradlew test --tests "kr.co.vividnext.sodalive.member.contentpreference.MemberContentPreferenceServiceTest.shouldReturnStoredRowWhenDuplicateInsertOccurs" --tests "kr.co.vividnext.sodalive.member.MemberServiceCacheEvictionTest.shouldEvictRecommendLiveCacheForRequesterAndTargetOnBlock" --tests "kr.co.vividnext.sodalive.live.recommend.LiveRecommendServiceTest.shouldDelegateToRepositoryWithAdultFlagWhenMemberIsAuthenticated"`
+  - 결과:
+    - 타깃 테스트 통과.
+    - 전체 검증(`ktlintCheck`, `test`, `build`) 통과.
+    - 핵심 수동 QA 성격 시나리오(중복 insert fallback, 차단 시 양쪽 캐시 무효화, 성인 플래그 전달 조회) 통과.
+    - Kotlin LSP 미구성으로 LSP 진단은 불가하여 Gradle 검증으로 대체했다.
+
+### 정정 (2026-03-27, 11차 중간 수정)
+- 무엇을:
+  - 11차 1차 테스트에서 `MemberContentPreferenceServiceTest` 검증문이 `save`를 확인하고 있어 실패한 항목을 `saveAndFlush` 검증으로 정정했다.
+- 왜:
+  - 동시성 보강 과정에서 서비스 저장 호출이 `save`에서 `saveAndFlush`로 변경되었기 때문이다.
+- 어떻게:
+  - 실패 명령:
+    - `./gradlew test --tests "kr.co.vividnext.sodalive.live.recommend.LiveRecommendServiceTest" --tests "kr.co.vividnext.sodalive.member.contentpreference.MemberContentPreferenceServiceTest" --tests "kr.co.vividnext.sodalive.member.MemberServiceCacheEvictionTest" --tests "kr.co.vividnext.sodalive.member.contentpreference.MemberContentPreferenceIntegrationTest"`
+  - 조치:
+    - `MemberContentPreferenceServiceTest.shouldCreateDefaultPreferenceWhenRowIsMissing` 검증 대상을 `saveAndFlush`로 교체
+  - 재실행:
+    - 동일 타깃 테스트 명령 재실행 통과
+
+### 12차 잠재 버그 재점검 (보강 후 재검토, 2026-03-27)
+- 무엇을:
+  - 11차 보강 코드 재검토 중 `initializeDefaultPreference`의 unique 충돌 fallback 재조회가
+    비잠금 조회(`findByMemberId`)로 남아 있던 지점을 추가 보강했다.
+  - fallback 재조회를 `findByMemberIdForUpdate`로 변경해, REPEATABLE READ 스냅샷 영향으로 row를 못 보는 가능성을 낮췄다.
+  - 회귀 테스트(`MemberContentPreferenceServiceTest.shouldReturnStoredRowWhenDuplicateInsertOccurs`)의 목 시퀀스를
+    변경된 fallback 호출 순서에 맞게 업데이트했다.
+- 왜:
+  - 충돌 예외 이후 같은 트랜잭션에서 비잠금 재조회를 수행하면 스냅샷 일관성 때문에 최신 row를 못 보고
+    예외 재전파로 끝날 수 있어, 충돌 복구 경로의 신뢰성을 높일 필요가 있었기 때문이다.
+- 어떻게:
+  - 명령:
+    - `./gradlew test --tests "kr.co.vividnext.sodalive.member.contentpreference.MemberContentPreferenceServiceTest" --tests "kr.co.vividnext.sodalive.member.contentpreference.MemberContentPreferenceIntegrationTest"`
+    - `./gradlew ktlintCheck test build`
+  - 결과:
+    - preference 서비스/통합 타깃 테스트 통과.
+    - 전체 검증(`ktlintCheck`, `test`, `build`) 통과.
+    - Kotlin LSP 미구성으로 LSP 진단은 불가하여 Gradle 검증으로 대체했다.

+
+### 1차 구현
+- 무엇을: `MemberService.memberBlock`에서 동일 `auth` 기반 다중 계정 확장 차단을 제거하고, `request.blockMemberId` 1건만 차단/재활성화하도록 수정했다.
+- 왜: 회원 차단 API가 요청한 대상 ID만 차단해야 하며, 동일 auth 계정 전체가 함께 차단되는 과차단 동작을 제거해야 하기 때문이다.
+- 어떻게:
+  - 탐색: explore 2개 + librarian 1개 백그라운드 분석, `grep`/`ast-grep`/`glob`로 호출 흐름과 확장 지점 확인.
+  - 코드 변경: `src/main/kotlin/kr/co/vividnext/sodalive/member/MemberService.kt`의 `memberBlock`에서 `authRepository.getMemberIdsByNameAndBirthAndDiAndGender(...)` 및 다중 루프 제거.
+  - 테스트 변경: `src/test/kotlin/kr/co/vividnext/sodalive/member/MemberServiceCacheEvictionTest.kt`에 `shouldBlockOnlyRequestedMemberEvenWhenTargetHasAuth` 추가.

+# 20260327 멤버 콘텐츠 선호 기본값 조정
+
+## 목적
+- `MemberContentPreference` 신규 생성 기본값을 다음 정책으로 고정한다.
+  - 기존 회원 + `member.auth != null` 인 경우: `isAdultContentVisible = true`, `contentType = ContentType.ALL`
+  - 그 외: `isAdultContentVisible = false`, `contentType = ContentType.ALL`
+
+## 구현 체크리스트
+- [x] 기본값 시드 로직을 `member.auth` 기준 정책으로 단순화한다.
+  - QA: row 미존재 + 인증/미인증 케이스에서 저장값이 각각 `true/ALL`, `false/ALL`인지 테스트로 확인
+- [x] 레거시 조회 파라미터(`isAdultContentVisible`, `contentType`)가 신규 row 기본값에 영향을 주지 않도록 정리한다.
+  - QA: `resolveForQuery` 호출 시 파라미터 전달 여부와 무관하게 정책 기본값으로 생성되는지 확인
+- [x] 관련 단위/통합 테스트 기대값을 정책에 맞게 수정한다.
+  - QA: `MemberContentPreferenceServiceTest`, `MemberContentPreferenceIntegrationTest` 통과
+- [x] 회귀 검증을 실행한다.
+  - QA: `./gradlew test --tests "kr.co.vividnext.sodalive.member.contentpreference.MemberContentPreferenceServiceTest" --tests "kr.co.vividnext.sodalive.member.contentpreference.MemberContentPreferenceIntegrationTest"`, `./gradlew build` 성공
+
+## 구현 완료 후 기록
+### 1차 구현
+- 무엇을:
+  - `MemberContentPreferenceService.initializeDefaultPreference`의 기본 seed를 `member.auth != null` 기준으로 변경해 인증 회원은 `true/ALL`, 그 외는 `false/ALL`로 생성되도록 수정했다.
+  - `resolveForQuery`의 신규 row 생성 seed 계산에서 legacy 파라미터를 제거하고 `member.auth` 기반 고정 정책(`true/ALL` 또는 `false/ALL`)만 사용하도록 정리했다.
+  - `MemberContentPreferenceServiceTest`, `MemberContentPreferenceIntegrationTest`의 관련 시나리오를 정책에 맞게 수정했다.
+- 왜:
+  - 요청사항이 “기존 회원가입 + `member.auth != null`이면 `true/ALL`, 그 외는 `false/ALL`”로 명확하여, 신규 row 기본값이 요청 파라미터에 영향을 받지 않도록 일관된 기준으로 통일해야 했기 때문이다.
+- 어떻게:
+  - 명령:
+    - `./gradlew test --tests "kr.co.vividnext.sodalive.member.contentpreference.MemberContentPreferenceServiceTest.shouldSeedPreferenceToTrueAndAllWhenRowMissingAndAuthenticatedRegardlessOfLegacyParams"`
+    - `./gradlew test --tests "kr.co.vividnext.sodalive.member.contentpreference.MemberContentPreferenceServiceTest" --tests "kr.co.vividnext.sodalive.member.contentpreference.MemberContentPreferenceIntegrationTest"`
+    - `./gradlew build`
+  - 결과:
+    - 정책 핵심 시나리오 단일 테스트 통과.
+    - 대상 단위/통합 테스트 통과.
+    - 전체 build(테스트/ktlint 포함) 통과.
+    - `.kt` 확장자용 LSP 서버가 현재 환경에 없어 `lsp_diagnostics`는 실행 불가였고, 대신 Gradle 검증으로 정합성을 확인했다.
+
+## 연계 작업(동일 기능)
+### 2차 구현 - `resolveForQuery` 조회 파라미터 제거
+- 무엇을:
+  - `MemberContentPreferenceService.resolveForQuery` 시그니처에서 미사용 파라미터 2개
+    (`isAdultContentVisible`, `contentType`)를 제거하고 `member` 단일 파라미터로 정리했다.
+  - 시그니처 변경에 맞춰 서비스/컨트롤러/테스트의 `resolveForQuery` 호출부 인자 전달 코드를 일괄 정리했다.
+- 왜:
+  - 실제로 사용되지 않는 파라미터를 제거해 함수 계약을 단순화하고, 호출부 가독성과 유지보수성을 높이기 위해서다.
+- 어떻게:
+  - 명령:
+    - `./gradlew compileKotlin compileTestKotlin`
+    - `./gradlew test --tests "kr.co.vividnext.sodalive.member.contentpreference.MemberContentPreferenceServiceTest" --tests "kr.co.vividnext.sodalive.member.contentpreference.MemberContentPreferenceIntegrationTest"`
+    - `./gradlew build`
+    - `lsp_diagnostics(filePath="src/main/kotlin", extension=".kt")`
+  - 결과:
+    - 시그니처 변경 직후 컴파일 에러로 표시된 호출부를 모두 정리한 뒤 `compileKotlin/compileTestKotlin` 성공.
+    - 관련 단위/통합 테스트 통과.
+    - 전체 build(ktlint/test 포함) 성공.
+    - 현재 환경에는 Kotlin LSP 서버가 없어 `lsp_diagnostics`는 실행 불가였고,
+      Gradle 컴파일/테스트/빌드로 정합성을 확인했다.
+
+### 3차 구현 - 수정 파일 미사용 파라미터 정리
+- 무엇을:
+  - `resolveForQuery(member = member)`로 단순화된 이후 미사용 상태가 된
+    `resolvePreference` 헬퍼 파라미터를 12개 파일에서 제거했다.
+  - 헬퍼 호출부를 정리했고, null 회원 분기에서 실제로 파라미터를 사용하는 서비스/컨트롤러
+    (`HomeService`, `LiveApiService`, `AudioContentController`, `AudioContentMainTabHomeController`)는
+    기존 전달 로직을 유지했다.
+- 왜:
+  - 사용되지 않는 파라미터는 경고와 혼선을 유발해 유지보수 비용을 높이므로,
+    실제 사용하는 함수 계약만 남겨 코드 의도를 명확히 하기 위해서다.
+- 어떻게:
+  - 명령:
+    - `./gradlew compileKotlin`
+    - `./gradlew test --tests "kr.co.vividnext.sodalive.member.contentpreference.MemberContentPreferenceServiceTest" --tests "kr.co.vividnext.sodalive.member.contentpreference.MemberContentPreferenceIntegrationTest"`
+    - `./gradlew build`
+    - `lsp_diagnostics(filePath="src/main/kotlin", extension=".kt")`
+  - 결과:
+    - `compileKotlin` 성공.
+    - 관련 단위/통합 테스트 성공.
+    - 전체 build(ktlint/test 포함) 성공.
+    - 현재 환경에 Kotlin LSP 서버가 없어 `lsp_diagnostics`는 실행 불가였고,
+      Gradle 컴파일/테스트/빌드 결과로 정합성을 확인했다.
+
+### 4차 수정 - 잔여 미사용 파라미터 추가 정리
+- 무엇을:
+  - 3차 정리 이후에도 남아 있던 수정 파일 내 함수 미사용 파라미터를 추가 제거했다.
+  - `resolvePreference(member: Member)`만 사용하는 컨트롤러들의
+    `@RequestParam("isAdultContentVisible")`, `@RequestParam("contentType")`를 제거하고 import를 정리했다.
+  - `ExplorerService.getCreatorProfile`의 미사용 파라미터 `isAdultContentVisible`을 제거하고
+    `ExplorerController` 호출부를 함께 수정했다.
+- 왜:
+  - 실제 로직에서 사용되지 않는 파라미터를 제거해 함수 계약을 단순화하고,
+    유지보수 시 혼선을 줄이기 위해서다.
+- 어떻게:
+  - 명령:
+    - `./gradlew compileKotlin compileTestKotlin`
+    - `./gradlew test --tests "kr.co.vividnext.sodalive.member.contentpreference.MemberContentPreferenceServiceTest" --tests "kr.co.vividnext.sodalive.member.contentpreference.MemberContentPreferenceIntegrationTest"`
+    - `./gradlew build`
+    - `lsp_diagnostics(filePath="src/main/kotlin", extension=".kt")`
+  - 결과:
+    - `compileKotlin`, `compileTestKotlin` 성공.
+    - 관련 단위/통합 테스트 성공.
+    - 전체 build(ktlint/test 포함) 성공.
+    - 현재 환경에 Kotlin LSP 서버가 없어 `lsp_diagnostics`는 실행 불가였고,
+      Gradle 검증으로 정합성을 확인했다.

+# 20260327 멤버 콘텐츠 선호 신규 생성 정책 수정
+
+## 목적
+- `resolveForQuery` 레거시 파라미터를 기존 row 갱신 용도로 사용하지 않고, **row 미존재 최초 생성 시에만** 제한적으로 사용한다.
+- 최종 목표인 "MemberContentPreference 저장값만 조회에 사용" 방향으로 정책을 단순화한다.
+
+## 최종 정책
+- [x] `MemberContentPreference` 없음 + `member.auth != null`
+  - 요청 파라미터(`isAdultContentVisible`, `contentType`)가 있으면 전달값으로 생성한다.
+  - 요청 파라미터가 없으면 `isAdultContentVisible = true`, `contentType = ContentType.ALL`로 생성한다.
+- [x] `MemberContentPreference` 없음 + `member.auth == null`
+  - `isAdultContentVisible = false`, `contentType = ContentType.ALL`로 생성한다.
+- [x] `MemberContentPreference` 있음
+  - `resolveForQuery`로 들어온 요청 파라미터는 무시하고 저장값만 사용한다.
+
+## 구현 체크리스트
+- [x] `MemberContentPreferenceService` 생성 경로(`initializeDefaultPreference`)가 초기값을 정책 기반으로 받을 수 있도록 수정
+  - QA: `resolveForQuery` 호출 시 row 유/무에 따른 생성값이 테스트에서 일치하는지 확인
+- [x] `resolveForQuery`에서 기존 row에 대한 레거시 파라미터 반영/캐시 무효화 제거
+  - QA: 기존 row + 파라미터 입력 시 저장값 불변 및 캐시 미무효화 테스트 통과
+- [x] 관련 단위/통합 테스트 갱신
+  - QA: `MemberContentPreferenceServiceTest`, `MemberContentPreferenceIntegrationTest` 통과
+- [x] 회귀 검증 실행
+  - QA: `./gradlew test`, `./gradlew ktlintCheck`, `./gradlew build` 성공
+
+## 구현 완료 후 기록
+### 1차 구현
+- 무엇을:
+  - `MemberContentPreferenceService`에 `PreferenceSeed`를 도입해 row 미존재 시 초기 생성값을 호출 목적에 맞게 주입하도록 변경했다.
+  - `resolveForQuery`는 더 이상 기존 row를 요청 파라미터로 갱신하지 않고, 저장값 조회 전용으로 동작하도록 수정했다.
+  - row 미존재 시 seed 정책을 다음과 같이 반영했다.
+    - `member.auth != null` + legacy 파라미터 존재: 전달값 기반 생성
+    - `member.auth != null` + legacy 파라미터 미존재: `true/ALL` 생성
+    - `member.auth == null`: 파라미터와 무관하게 `false/ALL` 생성
+  - `MemberContentPreferenceServiceTest`, `MemberContentPreferenceIntegrationTest`를 정책에 맞게 갱신/추가했다.
+- 왜:
+  - 기존 row를 조회 API 파라미터로 계속 갱신하면 "저장값 단일 기준" 목표와 충돌하므로, 레거시 파라미터 역할을 row 최초 생성 시점으로 한정하기 위해서다.
+  - 기존 회원 중 row 미존재 사용자의 초기 생성 경로를 명시적으로 제어해 운영 일관성을 확보하기 위해서다.
+- 어떻게:
+  - 명령:
+    - `./gradlew test --tests "kr.co.vividnext.sodalive.member.contentpreference.MemberContentPreferenceServiceTest" --tests "kr.co.vividnext.sodalive.member.contentpreference.MemberContentPreferenceIntegrationTest"`
+    - `./gradlew test && ./gradlew ktlintCheck && ./gradlew build`
+  - 결과:
+    - 정책 관련 단위/통합 테스트 통과.
+    - 전체 회귀 검증(`test`, `ktlintCheck`, `build`) 통과.
+    - `.kt` 대상 LSP 서버가 현재 환경에 없어 Kotlin LSP 진단은 수행 불가였고, 대신 Gradle 검증으로 대체했다.

+- [x] 예약 조회(`getLiveRoomListReservationWithDate`, `getLiveRoomListReservationWithoutDate`)의 성인 설정 필터 동작은 기존과 동일하다.
+- [x] 기존 코드 패턴을 유지하며 최소 범위로 변경된다.
+- [x] 변경 파일 LSP 진단 에러가 0건이다. *(Kotlin LSP 미지원 환경으로 `lsp_diagnostics` 실행 불가, 테스트/빌드 성공으로 대체 검증)*
+- [x] 관련 테스트/빌드 검증 명령이 성공한다.
+
+## 구현 체크리스트
+- [x] NOW/예약 목록 분기 및 성인 필터 전달 경로를 확인한다.
+- [x] NOW 목록 조회 경로만 정책에 맞게 수정한다. *(QA: NOW 경로 호출 인자 검증)*
+- [x] 예약 목록 조회 경로가 기존 로직을 유지하는지 검증한다. *(QA: 예약 경로 호출 인자/쿼리 유지 확인)*
+- [x] 익명 사용자(member=null) NOW 조회에서 성인 필터 우회 범위가 과도하지 않도록 조건을 보강한다. *(2차 가정, 3차에서 정책 정정됨)*

+
+## 검증 기록
+### 1차 구현
+- 무엇을: `LiveRoomService.getRoomList`의 NOW 분기에서 `isAdult = true`를 전달하도록 수정하고, 예약 분기는 기존 `isAdult` 전달을 유지했다. 또한 NOW/예약 전달 정책을 검증하는 `LiveRoomServiceAdultVisibilityPolicyTest`를 추가했다.
+- 왜: 진행 중 라이브 목록은 사용자 성인 설정과 무관하게 19금 방을 노출하고, 예약 목록은 기존 정책대로 사용자 설정을 반영해야 하기 때문이다.
+- 어떻게:
+  - 전달값 확인: `grep`으로 NOW/예약 분기의 `isAdult` 전달값 확인 (`isAdult = true` / `isAdult = isAdult`).
+  - LSP 진단 시도: `lsp_diagnostics` for `LiveRoomService.kt`, `LiveRoomServiceAdultVisibilityPolicyTest.kt` → **불가(환경에 Kotlin LSP 서버 미구성)**
+  - 정책 단위 테스트: `./gradlew test --tests "kr.co.vividnext.sodalive.live.room.LiveRoomServiceAdultVisibilityPolicyTest"` → **성공(BUILD SUCCESSFUL)**
+  - 관련 선호도 테스트: `./gradlew test --tests "kr.co.vividnext.sodalive.member.contentpreference.MemberContentPreferenceServiceTest" --tests "kr.co.vividnext.sodalive.member.contentpreference.MemberContentPreferencePolicyTest" --tests "kr.co.vividnext.sodalive.member.contentpreference.MemberContentPreferenceIntegrationTest"` → **성공(BUILD SUCCESSFUL)**
+  - 전체 빌드: `./gradlew build` → **성공(BUILD SUCCESSFUL)**
+
+### 2차 수정 (리뷰 피드백 반영)
+- 무엇을: `LiveRoomService.getRoomList`의 NOW 분기에서 `isAdult` 전달값을 `member != null || isAdult`로 조정해 로그인 사용자에게만 우회가 적용되도록 보강했다. 또한 `LiveRoomServiceAdultVisibilityPolicyTest`에 비로그인 NOW 조회 회귀 케이스를 추가하고, `MemberContentPreferencePolicyTest`/`MemberContentPreferenceIntegrationTest`에 `37543L -> JP` 강제 매핑 검증을 추가했다.
+- 왜: 기존 `isAdult = true` 고정은 익명 사용자까지 성인 진행중 라이브를 노출할 수 있어 정책 범위가 과도해질 수 있으며, 강제 JP ID 추가(`37543L`)는 테스트로 고정해 회귀를 방지해야 하기 때문이다.
+- 어떻게:
+  - LSP 진단 시도: `lsp_diagnostics` for 변경된 Kotlin 파일 4개 → **불가(환경에 Kotlin LSP 서버 미구성)**
+  - 정책/회귀 테스트: `./gradlew test --tests "kr.co.vividnext.sodalive.live.room.LiveRoomServiceAdultVisibilityPolicyTest" --tests "kr.co.vividnext.sodalive.member.contentpreference.MemberContentPreferencePolicyTest" --tests "kr.co.vividnext.sodalive.member.contentpreference.MemberContentPreferenceIntegrationTest"` → **성공(BUILD SUCCESSFUL)**

+
+### 정정
+- 정정 대상: `2차 수정 (리뷰 피드백 반영)`의 정책 가정(익명 NOW 노출 제한)
+- 사유: 요구사항 재확인 결과, NOW 목록에서 익명 사용자 노출은 의도된 기능이며 상세/입장 단계에서 인증 및 성인 검증을 수행하는 정책으로 확정되었다.
+- 변경 내용: NOW 분기의 익명 제한 보강(`member != null || isAdult`)을 제거하고, 익명 포함 우회(`isAdult = true`)로 복원했다. 관련 회귀 테스트도 익명 우회 기대값으로 정렬했다.
+
+### 3차 수정 (정책 정정 반영)
+- 무엇을: `LiveRoomService.getRoomList` NOW 분기의 `isAdult` 전달값을 `isAdult = true`로 복원했다. `LiveRoomServiceAdultVisibilityPolicyTest`의 익명 NOW 케이스를 `isAdult = true` 기대로 수정하고, 테스트명/DisplayName을 정책 의미에 맞게 변경했다.
+- 왜: NOW 목록은 익명 사용자에게도 노출하되, 실제 터치 후 상세/입장 단계에서 인증 및 성인 검증(`live.room.adult_verification_required`)을 수행하는 것이 의도된 정책이기 때문이다.
+- 어떻게:
