"""★야외 보충 스텝은 중앙 CP 를 **앞**에 둔다 — 없으면 legacy 로 사지 않고 선다.

실측 canary 4398a55dc0bb (2026-09-03): step_manifest 에 `outdoor_structure_form_reference → reference_acquisition`
의존이 없어 닫힘(32 스텝)에 중앙이 빠졌고, `acquisition_owner` 가 OWNER_OUTDOOR 를 돌려줘 야외 스텝이 제 legacy
경로로 5라운드(제공자 4회)를 샀다. 보충 CP 0 · journal 0 · projected_from None."""
