목적:
- 본 PM 가설 4회 누적 부정확 + 회귀 1회 → feedback_pm_root_diagnosis_priority 의무 적용
- 가설 즉시 중단·실측 우선 진단 도구 추가
- PD Play 영역 Console [Projectile] prefix 필터 → 호출 여부·other 정보·각 분기 reach·return 시점 정확 진단

진단 Debug.Log 영역 (prefix [Projectile][...] 통일·grep 영역):
- [Enter] OnTriggerEnter2D 진입 영역 (other.name·layer·t)
- [Return] _hitTargets duplicate
- [Return] PlayerController detected
- [LayerCheck] enemyLayer·otherLayer·hasEnemyController·isEnemy
- [Return] not Enemy
- [Return] Health component missing
- [Return] Health not alive (hp 정보)
- [Hit] damage 적용

회수 의무:
- PD Console 결과 수령 + 근본 fix 적용 후 본 진단 Debug.Log 일괄 제거 (대화로그 영역 명시)

PD 결정 (2026-05-09): "A 안으로 해" — 진단 Debug.Log 즉시 추가.
pm-auditor 통과 (조건부) + 권고 4종 수용.
