"""W22 직행 place-continuity (2026-07-10, Codex BLOCKING_1) — 결정론 잠금.

2회차 E2E 육안: 같은 장소 직행 샷 간 외형 drift. prev 연속성 ref 재도입 시
기본 previous_shot_continuity 지시(조명/무드만 사용)는 구조 일관성 신호가
아니고 TIME_LOCK 과 충돌 — 직행 전용 metadata
``outdoor_direct_place_continuity`` 로 전용 consumer 분기를 탄다:
- 캐논 실사/맵 = 장소 identity·topology 1차 SOT
- prev = 겹치는 영역의 stable visible details 연속성
- 본문(shot text) = 시간/조명/카메라/액션 SOT (prev 조명 복사 금지)
- prev 의 인물/포즈/구도 복사 금지
