Pins every GitHub Actions
uses:reference to an immutable 40-char commit SHA (keeping# vX.Y.Zcomments so Renovate/Dependabot can still propose updates), pins internalopus-pro/*refs that pointed at mutable branches, and adds a shell-onlyactions-pinned-checkworkflow that fails any PR reintroducing an unpinned ref.Why: mutable tags don't pin — an attacker with a maintainer token repoints the tag at a malicious commit (CVE-2025-30066, 23,000+ repos hit via
tj-actions). We had 100+ builds referencingtrivy-action@masterinside that action's ~12-hour compromise window.The check job is deliberately plain shell with
permissions: {}— the gate itself must not add another supply-chain dependency.Part of SEC-254.
