// 저장 왕복 시험용 — 화면 TS 를 node 로 묶어 저장 본문을 만든다.
// node helper_b05_save_payload.mjs <저장소 뿌리>  · 표준입력 = 작업 목록(JSON) · 표준출력 끝 줄 = 결과 목록
//   {op:"attach", entries:[관 응답], moves:[[옛, 새]], points:[{chainage_m, source}]} → attach 결과

//   {op:"culvert", server:[관 응답], pending:{측점:조각}, moves:{측점:새 측점}} → PUT 본문 points 또는 null
