- _PID_LINENO_FULL_RE: 7필드 고정 regex → 5~7필드 통합 (9차 P-9107-25A-F-n 등 미매칭 수정)
- _extract_pid_dxf_fast: 레이어 이름 하드코딩 제거 → FULL_RE 매칭 우선, LINENO 계열 레이어 힌트 보조
- MatchCategoryAsync: 배관번호 regex(_pipeLineNoRe) 체크를 prefix 룰보다 먼저 실행 → P-9117-20A-F-n 등이 power_equipment로 오분류되던 문제 수정
- pump extractor 프롬프트: 배관번호 SKIP/INCLUDE 예시 추가
- DB 기존 레코드 435건 pipings로 재분류 (직접 SQL)
- .claude/settings.json: LLM 모델명 하드코딩 제거
