"""PLAN 472 덧 (요구 272) — 관 파일 누가거리를 그대로 읽던 남은 서버 자리 = 지금 노선 관 자리.

관 지점 정본의 노선 지문이 지금 노선과 어긋난 저장분(옛 노선 누가거리 · 좌표는 지금 노선) —
측점 계획(`_load_pipe_points`) · 관 지점 GET · 화면 · 서버 상세 얹기(`attach_saved_shapes`)는 좌표로
얹는데 세월교 노면 하강(`ford_surface_drops`) · 물넘이포장 구간(`ford_pavement_ranges` ·
`tilt_ranges`) · 카드 이름(`relabel_pipe_stations`) · B07 관 글 재료(`load_note_sources`)는
파일 누가거리로 읽어 [저장] 재계산 · 상세 값이 화면과 갈렸음.
관 = 좌표 주인 · 파일 지문이 어긋나도 같은 값.
