## 구현/정리 내용

- failover candidate를 현재 selected rank 이후의 unused eligible target으로 제한해 quota 회복 시 이전 rank로 bounce하지 않게 했다.
- selector와 dispatcher에 exhausted primary 때문에 alternate가 최초 선택된 뒤 primary가 회복되는 no-bounce 회귀를 추가했다.
- 재오픈 전후 Gemini 1회와 Laguna 9회의 동일 worker-stage 실패 예산, terminal count 10, production 성공 시 현재 stage만 reset되는 동작을 검증했다.
