+
+## 검증 기록
+
+### 1) 작업계획 문서 작성
+- 무엇: 프로필 SNS 필드 전환 및 프로필 수정 UI 변경 작업을 단계별 체크리스트로 정의.
+- 왜: 일부만 반영된 상태에서 누락 파일 없이 일관되게 마이그레이션하기 위함.
+- 어떻게:
+  - `websiteUrl`, `blogUrl`, `kakaoOpenChatUrl`, `et_website`, `et_blog` 키워드 기준으로 Kotlin/XML 사용처를 탐색.
+  - 단계별로 실제 수정 후보 파일 경로를 체크리스트에 연결.
+- 결과:
+  - 계획 문서 `docs/20260224_프로필SNS오픈채팅전환.md` 생성 완료.
+  - 구현은 아직 미수행(체크박스 전체 미완료 상태 유지).
+
+### 2) 프로필 SNS 필드/수정 UI 오픈채팅 전환 구현
+- 무엇: SNS 필드 규격을 `instagram`, `youtube`, `kakaoOpenChatUrl`, `fancimm`, `x`로 통일하고 프로필 수정 UI에서 Website/Blog 입력을 제거 후 Open Chat 입력으로 대체.
+- 왜: 서버/클라이언트 모델 및 UI의 SNS 항목을 동일 스펙으로 맞추고, 부분 반영 상태를 해소하기 위함.
+- 어떻게:
+  - 모델/요청/뷰모델(`ProfileUpdateRequest`, `ProfileResponse`, `ProfileUpdateViewModel`)의 `websiteUrl`/`blogUrl` 사용부를 `kakaoOpenChatUrl`로 변경.
+  - 프로필 수정 화면(`activity_profile_update.xml`, `ProfileUpdateActivity.kt`)에서 `et_website`/`et_blog` 제거 후 `et_open_chat` 입력으로 교체.
+  - 조회 응답 모델(`GetCreatorProfileResponse`, `GetLiveRoomUserProfileResponse`, `GetRoomDetailResponse`, `MyPageResponse`) 필드명 통일.
+  - 노출 UI(`fragment_live_room_detail.xml`, `layout_user_profile.xml`)와 클릭 처리(`LiveRoomDetailFragment.kt`)를 오픈채팅 기준으로 변경.
+  - 문자열 리소스(`values/strings.xml`, `values-en/strings.xml`, `values-ja/strings.xml`)에서 Website/Blog 문구 제거 후 Open Chat 문구 추가.
+- 결과:
+  - app/src/main 기준 `websiteUrl`, `blogUrl`, `et_website`, `et_blog`, 관련 문자열 키가 제거되고 `kakaoOpenChatUrl`/`et_open_chat`/`screen_profile_update_open_chat_*` 기준으로 정렬됨.
+
+### 3) 진단/테스트/빌드 검증
+- 무엇: 변경 파일 정합성과 빌드 안정성을 검증.
+- 왜: 필드명/뷰 ID/바인딩 변경으로 인한 컴파일 오류를 사전에 확인하기 위함.
+- 어떻게:
+  - `lsp_diagnostics`를 수정된 Kotlin/XML 파일 전체에 실행 시도.
+  - `./gradlew :app:testDebugUnitTest :app:assembleDebug` 실행.
+- 결과:
+  - LSP: 현재 환경에서 Kotlin/XML LSP 미설정으로 진단 도구 사용 불가(`No LSP server configured for extension: .kt/.xml`).
+  - Gradle: `BUILD SUCCESSFUL` (unit test + debug assemble 통과).
+
+### 4) `fancimmUrl`/`xUrl` 필드 추가 반영
+- 무엇: 기존 SNS URL 필드가 정의된 응답 모델 구간에 `fancimmUrl`, `xUrl`를 추가.
+- 왜: SNS URL 필드 스키마를 모델 간 일관되게 유지하고, 서버 응답 확장 시 누락 파싱을 방지하기 위함.
+- 어떻게:
+  - `GetCreatorProfileResponse.CreatorResponse`, `GetLiveRoomUserProfileResponse`, `GetRoomDetailManager`, `MyPageResponse`에 `@SerializedName("fancimmUrl")`, `@SerializedName("xUrl")` 필드를 추가.
+  - `grep`으로 `fancimmUrl|xUrl` 사용처를 재탐색해 대상 파일에 반영 여부 확인.
+  - `lsp_diagnostics` 실행 시도 후 `./gradlew :app:testDebugUnitTest :app:assembleDebug` 수행.
+- 결과:
+  - 대상 4개 모델 파일에 `fancimmUrl`, `xUrl` 필드 추가 완료.
+  - LSP: Kotlin LSP 미설정으로 진단 도구 사용 불가(`No LSP server configured for extension: .kt`).
+  - Gradle: `BUILD SUCCESSFUL` (unit test + debug assemble 통과).
