Merged
Conversation
Automated supply-chain hardening (OWASP CICD-SEC-4). Every action uses: is repinned from its mutable tag to the 40-char commit SHA it resolves to today (identical code, immutable). Original tag kept as # <tag> comment for Dependabot. Pinned 8 reference(s). No behavioural change.

What
Automated supply-chain hardening: repins every GitHub-Action
uses:(workflows + composite actions) from a mutable tag/branch to the full 40-char commit SHA it resolves to right now, keeping the tag as a# <tag>comment.Pinned 8 reference(s).
Why
A
@v4tag is mutable — whoever controls it can repoint it at different code that then runs in CI with our secrets (OWASP CICD-SEC-4). A SHA is immutable. Prerequisite for the org-wide 'require actions pinned to a full-length commit SHA' policy.Safety
