- 표지 = 기계 줄 맨 위 칸 `비활성: true`(없음 = 켜짐 · 값 묶음 밖) · 틀 검사 = 기계 줄에만 true(check_master OFF)
- M01 기계 목록 = 끝 열 「사용」 스위치(초안 → 페이지 [저장] · 자동저장 없음) · 끈 줄 흐림 · 머리 「비활성 같이 보기」(끄면 서버 rows state 「켜짐」)
- 뺌 = 요소 찾기 창(elements · 찾아 넣기 · 단가산출 기계 창) · logic-lib rows · M01 시험 계산 기계 고르기 표 · 내 기계 「비슷한 기계에서 시작」 ·
  불러오기 기계 잇기(M02_Machine_Find 표) · 기계경비식 「기계」 옵션(새 GET /api/m02/df/machine-off · 고른 값은 남기고 「· 비활성 기계」 꼬리)
- 셈 길은 그대로 — 끈 기계를 쓰던 단가산출 · 사본 값 같음
- 자료 = 해상장비 79 대(펌프 준설선 13 · 그래브 준설선 10 · 하천골재채취선 7 · 기중기선 5 · 예선 9 · 양묘선 11 · 토운선 6 · 이우선 2 · 대선 16) 끔
- 시험 = test_842_2_machine_off 새로 · test_804_10 옵션 글 단언을 새 글로 고침(끈 기계 거름이 들어간 줄)
