"""PLAN 429 — [저장] 길 정합(분석 424 9장 ④⑤⑧⑨).

- ④ 노선 [저장] 뒤 횡단 저장 = 고침이 없어도 한 번(서버가 지금 종단으로 횡단을 다시 셈 · 뒤에
  나간 계획고 초안이 횡단 설계 높이에 실림) · 서버 [저장]이 횡단 설계 높이를 저장 종단에서 냄.
- ⑤ 상단측 차례(`sync_uphill_overrides_into_designs`)가 소단 · 깎기 경사 · 조절 값을 남김.
- ⑨ 추가 측점 = 계산 묶음 입력(stations 부터 다시) · 가게 초안 바뀜 · 되돌리기 → 묶음에 넣음.
  [저장] 차례 실패 = 그 차례에서 멈춤(`test_design_store_save.py`).
Node 헬퍼 = `helper_429_save_path.cjs`.
