SEC-178: pin GitHub Action refs to full SHAs#5
Merged
Conversation
Pins actions/checkout@v6 and actions/setup-python@v6 in ci.yml and publish.yml to the full commit SHAs of the v6 tags as of 2026-04-21. Required before the org-wide sha_pinning_required policy (rootlyhq/terraform-rootly#891) lands; otherwise this repo's CI would fail validation at the "Set up job" step on first run after apply. SHAs: actions/checkout@v6 -> de0fac2e4500dabe0009e67214ff5f5447ce83dd actions/setup-python@v6 -> a309ff8b426b58ec0e2a45f0f869d46889d02405 Linear: SEC-178 (follow-up to SEC-89).
