Purchase more credits in the billing tab to continue. ⌛ How to resolve this issue?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 credits. 🚦 How do rate limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan refill rate. 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, the refill rate gradually slows as usage increases. The highest same-day bursts are limited more strictly.

fail() は Jest 27 以降でグローバルから削除されており、Jest 30（このプロジェクトで使用中）では ReferenceError: fail is not defined が発生してテストスイート全体が落ちます。expect(addButton).not.toBeNull() に置き換えることで同等のアサーションが安全に行えます。

実コンポーネント（PopularArticleCard.tsx 50〜55行）では isFullyCached フラグに関係なくキャッシュバッジが常にレンダリングされます。そのため isFullyCached: true のときにバッジが表示されることを確認しているように見えますが、isFullyCached: false でも同じテストが通ってしまいます。isFullyCached: false のケースを追加して、バッジが非表示になるかどうかを確認するか（コンポーネント側の修正も必要）、あるいはコメントで「常時表示が仕様」と明示することを推奨します。

**キャッシュバッジのアサーションが誤解を招く**

Greptile Summary
PopularArticleCardコンポーネントに対するユニットテストを新規追加するPRです。記事情報のレンダリング、カードクリックによる読み込み動作、プレイリスト追加ボタンのクリック動作の3ケースをカバーしています。fail()グローバル（Jest 27 以降で削除済み）を使用しており、Jest 30 環境下ではReferenceErrorが発生してテストスイート全体がクラッシュします。isFullyCachedフラグに関係なくキャッシュバッジが常にレンダリングされるため、isFullyCached: true限定の挙動を検証しているように見えるアサーションが実際には無条件に通過します。Confidence Score: 3/5
追加されたテストが Jest 30 環境下でクラッシュするため、そのままではCIが通りません。
fail()のランタイムエラーによりテストスイート全体が実行不能になります。修正は1行の置き換えで済みますが、修正前にマージするとCIが壊れます。packages/web-app-vercel/components/tests/PopularArticleCard.test.tsx の
fail()呼び出し（76〜78行付近）を重点的に確認してください。Important Files Changed
fail()グローバルを使用しているため実行時エラーが発生し、またisFullyCachedに連動しないキャッシュバッジアサーションが誤解を招く。Sequence Diagram
