How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

💡 What:
src/newsdom_api/equivalence.py파일의_article_has_headline함수 내에서bool(headline.strip())대신not headline.isspace()를 사용하도록 수정했습니다.🎯 Why: 기존
.strip()호출은 가시적인 텍스트 존재 여부를 확인하기 위해 불필요하게 문자열을 메모리에 새로 할당(allocate)하는 성능 안티패턴(anti-pattern)이었습니다.📊 Impact: 많은 양의 텍스트 데이터를 처리하는 핫 패스에서의 불필요한 문자열 할당 및 가비지 컬렉션(GC) 오버헤드를 감소시킵니다.
