Next review available in: 34 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 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. Review details⚙️ Run configurationConfiguration used: Organization UI Review profile: CHILL Plan: Pro Plus Run ID: 📒 Files selected for processing (3)

Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The publisher now uses atomic branch leasing and structured PR publication, but its failure cleanup can still close a PR without revalidating its marker, proposal head, and base. If those values change, the workflow could close a changed PR owned by another actor, so this should be fixed or explicitly accepted before merging. Sequence Diagram(s)sequenceDiagram

main2db716d7252603689b2cc18b700bac25e872b28fstill publishes the hourly NVIDIA NIM proposal branch with a check-then-actgit ls-remotefollowed by an unguarded push, and error cleanup deletes the branch by name. That can overwrite or later delete a same-name ref owned by another actor.This is a clean current-main successor for only the unique atomic publisher behavior from stale Draft #80. No predecessor checks, reviews, or scanner evidence transfer.
Test-first RED
test/hourly-product-development-publisher-lease.test.tsfirst requires:The protected-main publisher fails that contract because it uses
git ls-remote, unguardedgit push origin HEAD:...,git push origin --delete, andgh pr create.GREEN implementation
The trusted publisher now captures the exact proposal commit and uses explicit
--force-with-lease=<ref>:<expect>compare-and-swap semantics for both expected-absence creation and exact-head cleanup. Pull-request publication uses GitHub REST with a 256-bit correlation marker, recoverable numeric identity, exact server-side head/base revalidation, and full pagination before success is reported.The current #366 authority split is preserved: the NVIDIA credential-bearing proposer still has
bash: deny; the immutable proposal is executed only by the separate uncredentialed verifier; publication remains a credential-bearing non-executing Maintainer App stage.Evidence and references
docs/doctoring/atomic-product-publisher-lease.mdrecords the threat model, ordering invariant, rollback boundary, and APA 7 primary references. Git 2.55.0 documents explicit--force-with-lease=<refname>:<expect>semantics; GitHub's current Pull Requests REST API supplies structured create/get/list and pagination; NIST SP 800-218 provides the secure-development integrity/least-authority rationale.Requested exact-head verification: application
ci,reviewer-ci, eligible protected-base centralSecurity Scan, configured 100% owned production statement/branch/function/line coverage, package/security/SBOM/provenance gates, and current review/thread state.Version / release decision
No version bump, release, deployment, license choice, KPI/revenue claim, or acquisition-readiness claim. Release inventory is still empty and operational/legal/commercial acceptance remains separate.
