+### [2026-03-21] Idle→Resume 신호 소실 — 3중 버그
+- **증상**: AG 장시간 idle 후 작업 재개 시 Discord 승인 신호가 전달되지 않음
+- **원인**: (1) `ws-client.ts` `auth_fail` 시 `shouldReconnect=false` — JWT 24h 만료 시 WS 영구 종료. (2) `hub.py` `_disconnect`에서 유일 연결 시 `pending_owners` 삭제 — 재연결 후 Discord 버튼 무효. (3) `step-probe.ts` `stallProbed=true` + `lastPendingStepIndex=N`이 WS 재연결 시 리셋 안 됨 — WAITING step 재전송 영구 차단
+- **해결** (v0.5.2): (1) `auth_fail` → `registrationCode` 재시도. (2) `pending_owners` orphan 마커로 보존+재할당. (3) `resetPendingStateForReconnect()` + `onConnected`에서 호출
+- **주의**: WS `onConnected`에서 반드시 step-probe 상태 리셋 필수. `stallProbed`/`lastPendingStepIndex`는 TTL 없는 영구 값
