Warning

Review limit reached

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

Next review available in: 5 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

SessionConfig::compact_threshold now normalizes values above 100 during default construction, builder updates, and serde deserialization. Tests cover these paths and valid values. The changelog documents the behavior.

Changes

Layer / File(s)	Summary
Construction and deserialization normalization src/config.rs, CHANGELOG.md	A shared clamp helper limits default and builder values to 100. A serde helper applies the same limit during deserialization and preserves deserialization errors. Tests cover defaults, high values, and valid values. The changelog documents the behavior.

Verify each finding against current code. Fix only still-valid issues, skip the
rest with a brief reason, keep changes minimal, and validate.

Inline comments:
In `@src/config.rs`:
- Around line 153-154: The documentation in src/config.rs lines 153-154 must
state that serialization remains a JSON number while out-of-range
compact_threshold values are normalized during deserialization, rather than
claiming identical round-tripping. Update CHANGELOG.md line 12 to remove the
“every construction path” wording and the claim that Default carries an
out-of-range value, and explicitly document that public struct literals bypass
normalization.
