 ## adminfront 동작
 
 - `super_admin`은 사이드바의 `데이터 정합성` 메뉴에서 리포트를 볼 수 있습니다.
+- `다시 검사` 실행 중에는 버튼이 비활성화되고 `검사 중` 상태가 표시됩니다. 요청이 끝나면 완료 또는 실패 상태 문구가 화면에 남습니다.
 - `super_admin`은 같은 메뉴에서 유령 로그인 ID 대상을 확인하고, 체크박스로 선택한 뒤 확인 대화상자를 거쳐 삭제할 수 있습니다.
 - `super_admin`은 adminfront 개요 화면 하단에서도 최종 검증 상태, 실패 건수, 검사 시각, 섹션별 상태 요약을 볼 수 있습니다.
 - `tenant_admin` 등 non-super role은 화면 접근 시 권한 없음 메시지만 봅니다.
