💡 What: App.tsx에서 활성화된 검색 필터가 있을 때 React Flow가 노드를 다시 그리는 것을 막기 위해 visibleNodes의 객체 재생성을 WeakMap을 사용하여 캐시했습니다.
🎯 Why: nodes.map()을 사용하여 매번 새로운 객체를 반환하면 React Flow의 얕은 비교(shallow memoization)가 깨져 노드 이동 시 매 프레임마다 전체 트리가 다시 렌더링(re-render)되고 프레임 드롭(16ms 오버)이 발생합니다.
📊 Impact: 그래프 이동 중 불필요한 DOM 재렌더링을 방지하여 60fps 상호 작용 성능을 유지합니다.
🔬 Measurement: 검색 필터가 활성화된 상태에서 노드를 드래그할 때 React DevTools Profiler를 통해 렌더링 비용(Render duration)이 크게 감소하는 것을 확인할 수 있습니다.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request.

When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down.

I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job!

For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with @jules. You can find this option in the Pull Request section of your global Jules UI settings. You can always switch back!

New to Jules? Learn more at jules.google/docs.


For security, I will only act on instructions from the user who triggered this task.

Warning

Review limit reached

@seonghobae, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 29 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

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.

Please refer docs for additional details.

Superseded by #693, which implements the same WeakMap-cached visibleNodes data decoration in App.tsx plus the snapshot-polling race fix and the focused tests. Closing as duplicate.
