"""기성 단계 — 계약 → 기성내역 · 기성 제잡비 계산서 **구조**가 서는가 (PLAN 12장 · 2026-09-14 배정).

⚠ 값이 맞는지는 못 잰다 — 기성 표본 0건(STmate 27번 §9 · 35번). 여기서 재는 것:
    ① ⭐ 제잡비 줄 = 금회직접공사비 × 계약잡비율(도급액 ÷ 계약 직접공사비)
       — 줄마다 밑수×요율 다시 안 셈
    ② 계약 · 전회(앞 회차 금회의 합) · 금회 · 누계 네 칸과 각 비율 · 기성(%) · 잔량
    ③ 부가세 넷 — 직접입력 · 공급가액 · 재료비 · 재료비+산출경비
    ④ 계약 줄(입력) 불변 · 분리발주 폐기물은 제잡비 밖 · 틀린 칸 거름
