🎯 작업 내용
Issue #49의 Pose Matcher Raw 결과가 Alignment Policy를 거쳐 Camera UI 상태와 사용자 Feedback으로 변환되는 흐름을 재검증하고, FPS와 detector lifecycle에 영향을 받던 안정화 정책을 정리했습니다.
기존 sample 기반 EMA와 stable count를 경과 시간 기반 정책으로 전환하고, matcher 실패·카메라 비활성·detector 중단 상황에서 이전
ALIGNED상태가 남지 않도록 lifecycle 경계를 보완했습니다.🔍 기존 문제
기존 EMA와 초기 안정화 조건은 frame sample 수를 기준으로 동작해 실제 inference FPS가 달라지면 사용자 체감 시간이 달라졌습니다.
또한
ALIGNED상태에서는 smoothed score만 이탈 조건으로 사용해 matcher가 component 조건 실패로aligned=false를 반환해도 상태가 계속 유지될 수 있었습니다.카메라가 비활성화되거나 detector가
idle/error또는 frame stall 상태가 되어도 새 observation이 없으면 기존 Alignment snapshot이 남는 문제도 있었습니다.✅ 주요 변경 사항

🧪 확인 사항
ALIGNED이탈 확인📌 참고 사항
Matcher는 Raw 판정만 생성하고, EMA / hysteresis / hold / Feedback 제어는 Alignment Policy가 소유합니다. Guide hook은 React lifecycle과 no-frame timer 연결만 담당합니다.
Threshold와 tint 수치의 실기기 조정은 이번 구조적 안정화와 분리했습니다. 정책 값은 설정 모듈에 모아 두었으며, 실제 기기 데이터가 확보되면 별도 calibration 작업에서 조정할 수 있습니다.
대상 파일의 lint에는 오류가 없으며, 기존 effect 동기화 관련 경고 2개는 남아 있습니다. 이번 PR에는 Issue #47, #48의 미커밋 변경을 포함하지 않았습니다.
