"""M02 흐름도 — 옛 로직 줄 → 흐름도 변환(M02_DF_Convert) 시험 (PLAN 36-2).

· 꼴 시험 — 견본 로직 몇을 옮겨 상자 · 선 · 규칙 · 자동 배치(겹침 없음)를 봄
· 전수 대조 — 사본 폴더(tmp/master_copy_36 · AISLO_MASTER_DIR)의 로직 1,472 마다
  옛 셈(master_formula.run) = 변환 흐름도 셈(Compute.run) · 입력 = check_master.시험입력(정함 ①)
  · 기본 입력(줄의 시험입력 뺌)도 같이 · 맞는 비율 · 안 맞는 까닭 → tmp/convert_report_36.json
· 조건 찾기 field 「키」(입력값으로 요소 고르기 · 정함 ②) · 표 값 식 글 → 수(정함 ③)는 서버 길로
  (Compute · Values · sub4) · 값 찾기(dv.one_value)는 같은 물음이면 한 번만 셈
