"""M02 일위대가 맞춤 — 블록 하나 셈 · 판정(PLAN 338-1 · 설계 2-1 · 2-6 · 3-2).

블록 + 줄 → 엑셀 지문(`Finger`) → 이름 · 근거 차례(`Match.b_order`) → 지문 순위 섞기(`Fit`) ·
같음 1위 고정(딱 맞음이 이김) → 섞인 줄 몫 먼저 · 조합(`Combine.solve` · 근거 안 닿은 덧 = 후보 끝)
→ 위 다섯 옵션 거꾸로(`Option`) →
위 다섯 가운데 딱 맞음(옵션까지)이 있는데 1위가 아니면 그것이 1위(조합 없는 줄) →
판정 맞음 · 다른 점 · 후보 + 후보 다섯(로직마다 옵션 판정 꼬리표).
