Summary#
외부 스키마, 락파일, 플랫폼 식별자, 직렬화 입력처럼 시스템 바깥에서 들어오는 값은 작은 드리프트만 있어도 캐시 오염, 잘못된 결과, 치명적 크래시로 이어진다. 내부 로직 깊숙이 넘겨서 가정이 깨지게 두지 말고, 경계에서 현재 기대치와 맞는지 검증한 뒤 안전하게 거부하거나 null/skip으로 처리하는 편이 낫다. 가능하면 에러 메시지에는 바로 취할 수 있는 복구 방법도 함께 담아라.
Problem#
의존성 버전 변화, stale lockfile, 잘못된 shape index, 변경된 API 필수 필드 같은 입력 드리프트가 조용한 오동작이나 뒤늦은 런타임 실패를 만든다.
Solution#
캐시 키 계산, 역직렬화, 외부 API 매핑, 빌드/실행 전 단계에서 입력과 환경을 선검증하고, 불일치 시 안전하게 중단하거나 완화된 반환값을 사용한다.
Failure Modes#
- stale lockfile이나 플랫폼 차이를 무시해 잘못된 캐시 아티팩트를 재사용함
- malformed input을 내부 자료구조까지 전달해 CHECK/ASan 수준의 실패를 유발함
- 외부 라이브러리 스키마 변경을 그대로 받아 ValidationError나 빌드 파손이 발생함
