Line 31의 meterRegistry 필드는 탭으로 들여쓰기되어 있습니다. 탭을 4개의 공백으로 변경하세요.
As per coding guidelines: src/main/java/com/assu/server/**/*.java는 Java 17과 4-space indentation을 사용해야 합니다.

@Async 이벤트 처리에도 requestId를 전파하세요.
이 경로는 MVC ASYNC 디스패치가 아닙니다. ReportController가 ReportServiceImpl을 호출하고, ReportProcessedEvent가 ReportStatusSyncService.handleReportProcessed로 전달됩니다. 이 핸들러가 비동기로 실행되면 RequestIdFilter의 스레드 로컬 MDC를 상속하지 않으므로 로그에서 requestId가 사라질 수 있습니다. TaskDecorator 또는 ContextSnapshot을 @Async 실행기에 적용하고, Spring AsyncConfigurer와 SLF4J MDC 기준의 전파 테스트를 추가하세요.

이후 Grafana Cloud 실데이터 점검과 CodeRabbit 리뷰에서 나온 문제, CI 실패, 클러스터 모니터링 미수집 문제를 함께 수정했다.
