     * default 분기가 존재하는 이유: {@link ClientFacingErrorCode}가 non-sealed이므로
19 
     * (application/presentation 외 모듈도 레이어 경계를 넘지 않고 자체 구현을 추가할 수 있다)
20 
     * 컴파일러가 exhaustiveness를 강제할 수 없다. 새로운 구현이 매핑 테이블에 누락된 채
21 
     * 들어오면 조용히 500이 되는 대신 WARN 로그로 드러내어 운영 대시보드에서 식별 가능하게 한다.
22 
     *
23 
     * "새 ClientFacingErrorCode 구현은 반드시 매핑 테이블에 등록해야 한다"는 아키텍처 차원의
24 
     * 게이트는 ApiErrorHttpStatusMapperClientFacingCoverageTest에 있다.
