eomsangdonandClaude Opus 5 704a10b648 knowledge(제비율): 요율 옆에 밑수·처리 규칙을 실음 + 코드와 맞대는 거울 시험 
요율 숫자만으로는 그 데이터를 보고 금액을 되짚을 수 없었음. 밑수를 무엇으로 잡고
어떻게 자르는지가 코드에만 있어, 데이터를 갈아 끼운 사람이 규칙이 바뀐 줄 모름.

- 빠져 있던 밑수 한 칸(건설기계대여대금 지급보증수수료)을 채움.
- 처리 규칙을 데이터에 실음 — 자르는 법(줄 버림·관급자재대 천원 올림) · 안전관리비
  A·B 두 식과 1.2·1.1 · 조달수수료 차감 없음 · 이윤 밑수 · 규모 구간 판정.
- 거울 시험 6개 — 한쪽만 바뀌면 멈춤. 금액은 안 바뀜(1208 통과·실패 0).
