"""192-1 — 종단 계획선 숨은 꺾임(검증_랩탑메인 226fc805 · No.38+9).

까닭: 관을 769.28 → 769.38(0.1m) 옮김 → 「측점 있음」 판정 폭이 0.5m 라 측점이 옛 자리
769.28 에 남음 → B06(측점 769.28)과 B05(관 769.38) 두 자리에 계획고 편집이 남아 0.1m 사이
−465% 계단 · 769.38 은 측점선 없는 꼭짓점.
고침: 판정 폭 0.005m(측점 스냅 폭) · 측점을 다시 뜨면 사라진 측점의 꼭짓점 · 편집을 지움
(반올림 차이 0.006m 안은 옮김). 자료 = 고정 사본(fixtures/b05_192_1_moved_pipe_longitudinal.json ·
226fc805 종단 460~840m · 측점 769.28 인 192 이전 상태 · 213-2) — 사용자 storage 에 기대지 않음.
