# Keep the SHA-pinned GitHub Actions current (security fixes land silently behind a pin).
# Scope is github-actions ONLY: Dependabot has no Nix flake ecosystem, so flake.lock stays
# owned by the weekly flake-update.yml workflow. Bumps open as manual-review PRs (consistent
# with this repo's no-auto-merge posture) and trigger flake-check via pull_request.

day: monday # lands alongside the weekly flake-update PR
# Supply-chain hardening: don't adopt a brand-new release the instant it lands (the window
# where a compromised/yanked release is most likely still live). Applies to version updates
# only — GHSA-driven security updates still open immediately.
