❌ Failed checks (3 warnings)

Check name	Status	Explanation	Resolution
Linked Issues check	⚠️ Warning	The release metadata and chart bumps do not implement the behavior changes required by #894 or #888.	Include the controller fixes for bounded claim backoff and template-build in-progress handling, or remove those linked issues from this release PR.
Title check	⚠️ Warning	The title names release 1.44.0, but the change set appears to be a 1.43.1 release bump, so it is misleading.	Rename it to match the actual release version and primary change, e.g. "chore(main): release 1.43.1".
Description check	⚠️ Warning	The description is a release note, but it omits the required template sections like Thinking Path, Verification, Risks, and Model Used.	Fill in the template sections: Thinking Path, Linked Issues, What Changed, Verification, Risks, Model Used, and Checklist.

✅ Passed checks (2 passed)

Check name	Status	Explanation
Out of Scope Changes check	✅ Passed	The changes stay within release scope: version, changelog, and chart image tag updates.
Docstring Coverage	✅ Passed	No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check.
