"""PLAN 322-0 전수 표 시험 — 구조물 42종 × 견본마다 일곱 갈래 결과를 기록(`golden_322_structures.json`)과 맞춤.

갈래 = 심는 측점(TS `structureStationMarks` · `pipeStationMarks` · 파이썬 `resolve_extra_stations`) · 카드 이름
(파이썬 측점 이름 · TS 미리 뜬 횡단 이름 · 표시 이름) · 형상 얹기 열쇠(파이썬 attach 차례 · TS `Section_Store` 초안 얹기)
· 3D 몸체 · 알약 띠 · 고르기 목록(B05 · B06 `pickGroups`) · 옹벽 물빼기.
견본 = 종류마다 기본값 한 벌(main) · 빈칸(blank) · 배관은 흄관(hume) 하나 더 — 점형 · 부지형 = 101 m · 구간형 = 93 ~ 113 m
(기준 101) · 관 지점 = 101 m(기슭막이 96 ~ 106 m) · 격자 = 0 ~ 200 m 20 m 마다.

기록 다시 쓰기 = `GOLDEN_322_RECORD=1` · ★ = 계획(PLAN_구조물표 4장)대로 바뀔 칸 — 기록에 「지금 → 다음」을 적고
`STAGE` 가 그 단계를 넘으면 다음 값과 맞춤. TS 쪽 = `helper_322_0_golden.cjs`(Node).
