Poem

🔒 Write access? Gone — just read will do,
The workflow locked down, neat and true.
Python six, artifact seven,
Maintenance upgrades feel like heaven.
Fallback paths now stay in lane,
Least privilege wins the security game! 🛡️

Warning

Review ran into problems

🔥 Problems

Stopped waiting for pipeline failures after 30000ms. One of your pipelines takes longer than our 30000ms fetch window to run, so review may not consider pipeline-failure results for inline comments if any failures occurred after the fetch window. Increase the timeout if you want to wait longer or run a @coderabbit review after the pipeline has finished.
