 - **해결**: CSP의 `script-src`에 `'unsafe-inline'` 추가. Extension `setupApprovalObserver()`에 CSP 자동 패치 로직 영구 추가
 - **주의**: `style-src`에는 `'unsafe-inline'`이 있어 스타일은 동작 → 스크립트만 차단되는 것이 함정. `connect-src`에 `http://127.0.0.1:*` 존재하여 HTTP fetch는 허용됨 (CSP 통과 시 통신은 문제없음). 이 CSP 이슈는 **V8 CachedData 이슈와 동시에 존재**하여 진단이 매우 어려웠음
 
+### [2026-03-09] 중복 승인 요청 — DOM scan + Step probe 동시 발동
+- **증상**: Discord에 같은 명령에 대해 승인 요청이 2개 도착
+- **원인**: DOM Observer가 `RunAlt+↵` 버튼을 감지하여 pending 생성 + Step probe가 `CORTEX_STEP_STATUS_WAITING` 감지하여 pending 생성 → 동일 step에 대해 2개 파일
+- **해결**: `writePendingApproval()`에 15초 dedup 윈도우 추가 — 최근 DOM observer pending이 있으면 step probe pending 스킵
+- **주의**: DOM scan은 제거 불가 — `Allow Once`, `Allow This Conversation` 등 step probe가 감지 못하는 UI 버튼 존재. 버튼 텍스트도 `(Alt|Ctrl|Shift|Meta)\+.*` 정규식으로 키보드 단축키 정제
+
+### [2026-03-09] Step probe reject → ResolveOutstandingSteps가 AI 작업 취소
+- **증상**: Discord에서 거부 클릭 → AI의 현재 step뿐 아니라 진행 중인 작업 전체가 중단
+- **원인**: step probe 경로의 `tryApprovalStrategies(approved=false)` → `ResolveOutstandingSteps` RPC 호출 → 이것은 step을 **CANCEL**하는 파괴적 동작
+- **해결**: step probe 경로에서 reject 시 `tryApprovalStrategies` 호출 제거. reject은 로그만 남기고 파기적 동작 없음. DOM observer 경로만 실제 Reject 버튼 클릭 허용
+- **주의**: `ResolveOutstandingSteps`는 이름과 달리 "해결"이 아닌 "취소". 승인에 절대 사용 금지 (이전 이슈 #55~59 참조)
