What it does

This is the Build M1 Wheels workflow from the pytorch/audio repository, a real project running GitHub Actions. It is shown here with attribution under its BSD-2-Clause license.

Below, Latchkey shows a faster, safer version produced by its optimization engine.

What changed

Add a job timeout so a hung step cannot burn hours of runner time.

1 third-party action is referenced by a movable tag. Pin it to the commit SHA (Latchkey resolves and applies this automatically) so a repointed tag cannot change what runs.

This workflow runs 2 jobs per trigger. On Latchkey the same minutes cost up to 58% less than GitHub-hosted, with zero queue time.
