- 브라우저 다시 셈(Cross_Refresh_Calc) · 묶음 cross 단계(Cross_Stage) 의 좌 깎기 고정 폴백 걷음
  · cross 단계는 이미 있는 uphillSide(Pipeline_Detail) 다시 씀
- 서버 [저장] 두 길도 같은 규칙 — 파이썬 stored_section_mode(Router_Design 셋 · SampleExtend)
  · Node Cross_Save storedOptions · Node 에 측점 uphill_side 넘김(Server_Calc_Prebuild)
  · 화면만 상단측이면 [저장] 뒤 좌 깎기로 뒤집혀 같이 고침
- 값 바뀜 = section_mode 없는 설계뿐(지금 DB 16 측점 · 한 프로젝트) · 그 밖 0 차
- 거울 시험 test_472_8_section_mode_default(파이썬 = Node = 브라우저 · 없음 = 상단측 적음)

지움
- flushDesignStore(design_store · 부름 0) — 시험 344-4 의 flush 대조 한 줄도
- b_page_state 옛 세션 열쇠 옮김(legacy · migrate) · b_project_switch 옛 키 머리
  — 옛 열쇠는 세션 저장소(탭 닫으면 사라짐) · 지금 코드가 안 씀 · storage · DB 에 없음
  · 시험 290-1 · 401 · 384-1 의 옛 키 줄 뺌
- 시험만 부르던 TS — planFootprint(346-2 거울은 footprintRecord + slopePieces 로 그대로)
  · shiftSegment · shiftMovingPoints(쉬프트 단추는 09-02 지움 · min_cover_guard 쉬프트 시험 뺌)
  · dropStationsNear(test_b05_station_merge.mjs 지움) · createIrregularStationsSection(부름 0)
  · generalStations(234-1 은 기본 맞춤 값으로 같은 것 잼) · sameSummaryItem
- test_b05_b06_save_roundtrip + helper_b05_save_payload 둘 — 프로젝트 936be972 storage 없어 늘 skip
  · 같은 저장 왕복은 test_472_6_design_save(창구 원자성) · test_449_save_pipes(관 PUT)
    · test_238_1_save_keeps_structure_stations(구조물 측점)가 잼

남김
- migrateLegacyStations — 부르는 곳 있음(design_view_profile_sections) · storage 에 비정규 측점 남음
- common_util_excavation 셋 — 지금은 운영이 부름(design_calc_node)
