Summary
uses:reference in workflows to a specific commit SHA@v4→ latest v4.x.y SHA) to avoid breaking changesWhy
Mitigates supply-chain attacks where a tag could be retargeted to malicious code. Pinning to a SHA is the recommended hardening practice.
Notes for reviewers
SiaFoundation/workflows@masteranddtolnay/rust-toolchain@stable|nightly(which use a branch ref intentionally), the pin uses the current branch tip SHA — future updates will require a follow-up PR
