Summary
WooCommerce intends to enforce full-length commit SHA pinning for GitHub Actions across the organization. This pins every remote action reference in this repository to the commit currently identified by its existing tag or branch, while retaining that human-readable ref in a comment.
Immutable action references reduce the risk that a moved or compromised upstream ref can silently change the code executed by CI, which narrows the supply-chain compromise surface.
Validation
git diff --checksuccessfully.Changelog
No changelog is needed because this changes workflow/action configuration only and is not shipped to merchants.
