 - 선박: 선박 검색 범위를 전체 캐시 대상으로 확대
 - HNS: 정보 레이어 패널 통합 (레이어 표시/불투명도/밝기/색상 제어)
 - HNS: 분석 생성 시 유출량·단위·예측 시간·알고리즘·기준 모델 파라미터 전달
+- HNS/사건사고: 분석 전용 뷰 모드에서 지도 오버레이 UI 요소 조건부 숨김 처리
 
 ### 변경
 - InfoLayerSection을 공통 컴포넌트로 이동 (prediction → common/layer)
 - 기상 탭: 지도 오버레이 컨트롤 위치 우측 상단으로 조정
+- 지도 공통: 컨트롤 버튼 패널(줌 등) 위치 우측 → 좌측으로 변경
 
 ### 수정
 - 선박: 라우터 전체에 requireAuth 미들웨어 추가
