+편집 창 [노선 추천]의 점수 · 미리 보기에만 쓴다 — 파일 · 캐시 · initial_snapshot · 확정 종단을
+바꾸지 않는다. 확정 체인의 종단 규칙(1차 계획고 = 지반고 · 2026-09-02 사용자 확정)은 그대로다.
+
+계산 자리 = 서버 단독(③) — 화면은 받은 측점 · 지반고 · 계획고를 그리기만 한다.
+
+방법:
+  1. 측점(20 m)마다 지반 횡단(±20 m · 0.5 m)을 DEM 에서 뜬다 — B05 측점 생성과 같은 꼴
+     (좌 = +offset · 상단측 = 좌우 평균 표고가 높은 쪽 · 그쪽 절토).
+  2. 측점마다 계획고 ±Δ 의 절 · 성 단면적 곡선 — B06 `compute_cross_design` 그대로(지반유형
+     리핑암 = B06 기본값) · `AREA_STEP_M` 간격으로 재고 사이는 직선 보간.
+  3. 동적계획(앞 두 측점 상태)으로 측점 계획고를 고른다 — 목표 = 절토(다짐 환산) + 성토 ㎥ +
+     λ × (성토 − 절토). λ 를 이분해 |절 − 성| / 큰 쪽이 허용(10 %) 안인 가장 작은 λ.
+     · 종단기울기 상한 — 넘지 못함.
+     · 종단곡선 — 측점마다 변화점(20 m)이라 곡선 반쪽이 직선의 0.45 를 못 넘어 L ≤ 18 m <
+       법정 최소 L(20 m 이상). 그래서 대수차가 곡선 생략 한도(비포장 5 %) 안이어야 함 — 넘으면
+       벌점(지형상 못 지킬 때만 넘음) · 넘은 변화점 수를 낸다.
+  4. 배관 덮개 — 제약은 끈 채(확정 체인과 같음) 관 자리 계획고 − 지반고 < 덮개 여유인 관 수만.
