"""프로젝트 집계 항목 복사본 완전체 (PLAN 25-2b · 25-2e · 26-2b · 임시 저장소 · 임시 마스터 사본).

복사본은 구조물마다(`templates/structures/{구조물 id}/` · 관은 `pipe@측점`).

- 지정 → [저장] → 폴더에 새 파일(입력연결 · 입력값 · 고른자재 · 단가) · manifest 가져온날 · 원본판
- 단가 묶음이 닫혀 있음 — 조합 37개 · 로직 170개를 마스터와 복사본으로 돌려 같은 값
- 마스터 단가 한 줄을 바꿔도 프로젝트 계산 그대로 · 목록에 「마스터 바뀜」 · 새로 가져오기 뒤 바뀜
  (입력값 · 고른자재는 같은 키면 살림)
- 쓰기 뒤 다시 읽기 같음 · 판 다르면 409 · 모양 틀리면 400 · 고친 복사본은 안 지움
- 옛 복사본은 읽을 때 채움 · 미리 가져오기 · 남의 프로젝트 403
