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.

147-222: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winDuplicate code-fence/blockquote tracking between
get_description_violationsandget_attribution_violations.Both functions independently reimplement the same line-classification state machine (fence-toggle detection, in-code-block tracking, blockquote skip). Extracting a shared line iterator/helper would reduce duplication and the risk of the two implementations drifting apart as the policy evolves.
