- (B) 종단도 기준(기울기 상한 · 최소고 강제 · 시작 측점) = 세션 초안 ?? 저장 노선 설정 — 두 보기가 그린 뒤 applyPageSettings 하나 · B06 이 받은 노선은 캐시에
- (C) 상세 강제 다시 받기 = 듣는 쪽 한 번(숨은 종단 보기 옛 객체 안 쥠) · [측점 만들기] 뒤 캐시 비우고 강제로 받음
- (D) [저장] 상단측 차례 = flushRouteParts 한 벌(노선 캐시 지표 조건 + 확정 지표면 id · 비정규 빈 목록) — 종단 보기를 열든 안 열든 같은 요청
- 시험 test_271_detail_notify · test_271_save_same · test_271_profile_settings · 옛 저장 시험 가짜 창구에 flushRouteParts
