# Security updates as pull requests: scripts/dependency-update finds the
# dependencies with a known vulnerability (osv-scanner, against OSV) that
# a newer version fixes, bumps them, and keeps one pull request —
# deps/security-cargo, for code/Cargo.lock — refreshed in place, closing
# it once there's nothing left to fix. The pull request is opened by the
# forge's CI account (gg-security) with this job's own token; its CI
# (audit.yml) is what shows the fixes landed. Merging it to master
# deploys, as any push there does (image.yml).
#
# Daily, before the nightly audit, and by hand from the Actions page (`gg ci dispatch
# dependency-updates`).
