Summary by cubic

Enable Codecov PR comments so coverage changes show up directly on pull requests by granting pull-requests: write in .github/workflows/ci.yml and updating codecov.yml (layout: "header, diff, flags, files"; require_base/head: true). require_changes: false is set temporarily to verify visibility and will be reverted in #8 after confirmation.

^{Written for commit fbdc61a. Summary will update on new commits.}

Warning

Review limit reached

@yk-lab, we couldn't start this review because you've reached your PR review rate limit.

More reviews will be available in 9 minutes and 14 seconds. Learn how PR review limits work.

Your organization has used up its prepaid credits, and credit purchases are no longer available. Enable the review add-on in the billing tab to keep reviews running — you're only billed for reviews past your plan's rate limits ($0.25/file).

⌛ How to resolve this issue?

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 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.

Please see our Fair Usage Limits Policy for further information.
