extractor 가 422 로 돌려주는 확정 실패 code 중 core 가 의미를 아는 건 2종뿐이었고, 나머지는 else 폴백으로 permanent_error 한 바구니에 들어갔다. 그 바구니는 이름대로 "영구 외부 오류"가 아니라 매핑 누락분을 받는 통이 되어 있었다. - 확정 실패 code 12종을 PERMANENT_TRANSLATIONS 표로 전수 매핑하고, 폴백은 모르는 code 방어로만 남긴다 (tolerant reader 유지) - ProductSnapshotException.noExtractableContent() 신설 (SNAPSHOT-003) - ProductExtractorException.blockedByTarget() 신설 (EXTRACTOR-003) - 메트릭 reason 에서 permanent_error 를 없애고 unreadable, blocked, extract_quality, internal_error 를 추가한다. UNTRUSTWORTHY_VALUE 는 not_product 에서 extract_quality 로 옮긴다 - reason 은 예외가 참조하는 ErrorCode 의 bucket 에서 파생한다 (ExtractionFailureBucket + ItemParsingMetrics.reasonOf, 두 워커 공용) - 계약 카탈로그(shared-infra/contracts/extraction-error-codes.yaml)와 매핑, reason 을 대조하는 메타 테스트 신설 + CI 에 infra 체크아웃 스텝 추가. 카탈로그가 없으면 skip 이 아니라 실패다 전이, 재시도 판정은 건드리지 않았다. 422 는 여전히 status 만으로 확정 실패이고, code 는 "그 실패를 무엇이라 부르고 어떻게 세는가"만 가른다.
같은 목적으로 같은 repo(TeamPiKi/infra)를 받는 두 소비자의 스텝이 갈리면 한쪽만 손보게 된다. extractor#32 가 쓰는 옵션 셋에 맞춘다. - ref: main (어느 브랜치가 정본인지 명시) - sparse-checkout: contracts (infra 전체 대신 필요한 디렉터리만) - persist-credentials: false (러너에 자격증명을 남기지 않는다)

Error를 추출 실패 경로에서 전파하세요.
두 워커의 추출 호출을 runCatching 대신 try/catch (e: Exception)으로 감싸세요. 현재 OutOfMemoryError가 FAILED 전이와 메트릭 기록으로 전달됩니다. 이미지 워커는 이후 raw 객체까지 삭제할 수 있습니다.
ItemParsingMetrics.reasonOf는 일반 Exception의 internal_error fallback만 유지하고, OutOfMemoryError 테스트 기대값은 제거하세요. 대신 두 워커에서 Error가 전파되는 테스트를 추가하세요.
