Warning

Review limit reached

@jongan69, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 91 minutes

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

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 PR replaces separate HTML entity replacements with unified named and numeric decoding. It also migrates package checks and CI installation to Bun 1.3.14 and pins GitHub Actions to commit SHAs.

Changes

Entity decoding and Bun CI migration

Layer / File(s)	Summary
Single-pass HTML entity decoding scripts/research/literature-search.mjs	Named entities use a shared lookup. Numeric entities use validated Unicode code points. Invalid entities remain unchanged.
Pinned Bun installation and checks .github/workflows/ci.yml, package.json	The project declares Bun 1.3.14. CI uses frozen-lockfile Bun commands, and GitHub Actions are pinned to commit SHAs.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to a3d43

The PR still leaves some valid HTML entities undecoded and permits invalid Unicode surrogate values, while its CI workflow preserves repository credentials for later commands. These create bounded correctness and security risks, so the changes are not merge-ready until both issues are fixed.
