name: dependency-review

# Supply-chain guardrails for dependency-update PRs -- for BOTH Dependabot
# and maintainers.
#
# Inspects the changed files, then conditionally runs Socket Firewall (sfw)
# install smoke jobs for the affected manifests, picking the firewall edition
# per PR:
#
#   - SocketDev org members on an in-repo (non-fork) PR -> Socket Firewall
#     ENTERPRISE through the socket-firewall environment and its
#     SOCKET_SFW_API_TOKEN secret (authenticated, full org-policy enforcement).
#   - Everything else -- Dependabot, forks, outside collaborators, or external
#     contributors -> Socket Firewall FREE (anonymous, no API token), which is
#     safe in the unprivileged `pull_request` context.
#
# Only Enterprise jobs declare the socket-firewall environment. Free jobs do
# not touch that environment or its token.
#
# Pattern adapted from SocketDev/socket-basics.
