# 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 in Cargo.lock, and keeps one pull
# request — deps/security-cargo — 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
# and packages.yml's build and tests) is what shows the fixes landed.
#
# Only the lockfile moves: a fix that needs a new major version in
# Cargo.toml, or code changed to suit it, is listed in the pull request
# and left for a person.
#
# Daily, before the nightly audit, and by hand from the Actions page
# (`gg ci dispatch dependency-updates`).
