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.

- Around line 179-185: Update the normalization and matches-export flow to load
candidate issues from existing.json and retain only model-provided IDs matching
canonical issue numbers from that data, while still excluding the current issue
and limiting results to five. Apply this validation to both duplicates and
related before writing GITHUB_OUTPUT, preserving the existing reason and
empty-result behavior.
