 ## Follow-ups
 
-- [ ] sut-prober JSON naming을 `JsonNamingPolicy.SnakeCaseLower`로 변경 (contract 엄격 준수). non-blocking.
-- [ ] diff-reporter: 실제 `diff-triager` 에이전트 통합 테스트 (현재 schema 단위 테스트로 대체, DoD #8 partial). non-blocking.
-- [ ] normalizer: `mask_volatile_settings` 규칙을 JSON-path 스코핑으로 제한 (현재는 필드명 전역 매칭). non-blocking risk.
-- [ ] normalizer: float epsilon 구성화 (현재 6 decimals 하드코딩). contract risks 섹션.

 - [ ] recorder/player: **라이브 SUT 수동 smoke test** — 60 FPS / 10회 중 9회 reliability DoD는 샌드박스 unit test 불가, 실제 환경에서 검증 필요.
 - [ ] player: `wait_for` UIA 이벤트 매핑 강화 (현재 host passthrough).
 - [ ] player: `UiaPlayerHost` uia_path resolver가 마지막 `@AutomationId`만 사용 — 전체 ancestor chain 지원 필요.
