Thanks for opening a backport.

Before merging, please confirm that it falls into one of the following categories (select one):

• Non-production code changes OR fixes for serious issues. Non-production includes test-only changes, build system changes, etc. Serious issues are defined in the policy as correctness, stability, or security issues, data corruption/loss, significant performance regressions, breaking working and widely used functionality, or an inability to detect and debug production issues.
• Other approved changes. These changes must be gated behind a disabled-by-default feature flag unless there is a strong justification not to. Reference the approved ENGREQ ticket in the PR body (e.g., "Fixes ENGREQ-123").

Add a brief release justification to the PR description explaining your selection.

Also, confirm that the change does not break backward compatibility and complies with all aspects of the backport policy.

All backports must be reviewed by the TL and EM for the owning area.

✅ PR #164783 is compliant with backport policy

Confidence: high
Backward compatible: true
Explanation: The PR is compliant based on the release justification provided in the PR body, which states that it is a 'non-production (release infra) change.' This aligns with the backport policy's exception for non-production and test-only changes. Moreover, the file changed, 'pkg/build/version.txt', falls under the category of development tools which are considered non-production files as per the policy.

❌ ENGREQ Check Failed: Please check one of the backport category checkboxes.
