"""Area #2 W5 — 4 site state migration verification.

source-grep regression — 4 production files (asset_readiness / scene_reference_service /
detail_steps / render_prompt_card) 의 v12 legacy ``ca.get("gaze_target")`` 읽기 패턴
폐기 + ``is_immobilized_state(ca["subject_state"])`` 단일 SOT 전환 검증.

Gate 1 (semantic regex ban): code 가 literal tuple ``("dead", "unconscious",
"severely_injured")`` 로 semantic state 판단 금지 — helper 만 사용.
Gate 2 (active prompt 오염): line 936 의 ``"dead/unconscious bodies"`` 같은 prompt
오염 표현 중립화 의무.
Gate 4 (fail-fast): ``ca["subject_state"]`` direct read — silent ``.get(..., "")``
fallback 금지.
