Warning

Review limit reached

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

Next review available in: 56 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.

📝 Walkthrough

Walkthrough

The build workflow removes the LLVM environment setting, adopts cachix/install-nix-action@v31, runs nix build, uploads the artifact, and limits the release dependency to the build job. The separate test-build workflow is removed.

Changes

Build workflow

Layer / File(s)	Summary
Nix build and release orchestration .github/workflows/build.yml	The build job uses the Cachix Nix installer and artifact upload without the LLVM environment setting or explicit flake check; release now depends only on build.

Estimated code review effort: 2 (Simple) | ~10 minutes

Poem

A rabbit hops through Nix’s bright stream,
Builds an artifact from a tidy dream.
The LLVM tag fades from sight,
Release follows one path just right.
“Hop, hop!” says Bunny, “CI takes flight!”

consistent with the names requested by the release job’s download steps. Update
the upload configuration near actions/upload-artifact@v7 or all corresponding
release download patterns so Linux and macOS artifacts resolve successfully,
preserving the existing OS and architecture naming scheme.
- Around line 28-30: Update the workflow steps using cachix/install-nix-action
and actions/upload-artifact to reference immutable commit SHAs instead of
mutable version tags. Preserve the current versions as comments if useful, while
keeping each action’s existing configuration unchanged.

Pin cachix/install-nix-action@v31 and actions/upload-artifact@v7 to immutable commit SHAs. Both are mutable tags, so keep the version only as a comment if needed.
