"""PLAN 472-6 6-B — 노선 바뀐 [저장]도 한 본문 · 다시 얹기 서버 Node(같은 TS).

  ① 넘김 — 브라우저 옛 길(세션 함수를 옛 `carryAfterRouteSave` → `saveCachedCrossPatches`
     차례로) 결과 == 서버 Node `stations.carry`(`routeCarryPatches`) 결과(patch · 버린 수) ·
     손 상단측 안 넘김(요구 274).
  ② 다시 얹기 — 관 · 구조물 초안(`rebasePipeDraft` · `rebaseStructureDraft`) ==
     Node `facility.rebase`.
  ③ 옛 코드 실패 — 한 본문이 `route` · `carry` 칸을 받음 · 브라우저가 노선 저장 창구를 안 부름.
  ④ 실제 창구(검증_sub8 DB · storage 는 임시 사본) — 노선 차례 뒤 실패(시험 갈래 · 넘김 실패)
     = 노선 행 · 자식 표 · storage(초기값 사본 포함) 그대로 · 정상 한 본문(교점 끌기) = 옛 차례
     (노선 저장 → 다시 얹기 → 횡단 저장)와 행 · 파일 같음 · 시설 수 그대로 · 초기값 그대로(493).
실DB(④)는 `AISLO_LIVE_DB=1` 일 때만 · 검증 프로젝트가 없는 자리(다른 PC · DB 없음)도 건너뜀.
