# Fast, focused supply-chain audit of every checked-in lockfile.
#
# Runs scripts/lockfile_supply_chain_audit.py on PRs that touch any
# npm or cargo lockfile, on push to main, and on a daily schedule so
# newly-published IOCs surface even when no PR opens.
#
# Default behavior is "advisory": only public indicator-of-compromise
# strings, known-malicious pinned versions, and structurally broken
# lockfiles fail the build. Structural anomalies (missing integrity,
# non-default registry, etc.) are emitted as GitHub Actions warnings
# but do not block merges. This deliberately keeps the noise floor
# low while still failing the moment a checked-in lockfile starts
# pointing at known-bad bytes.
#
# This workflow is intentionally separate from security-audit.yml:
#   - security-audit.yml is the umbrella job (pip-audit + npm audit +
#     cargo audit + OSV + Semgrep + secret scanning + SBOM + ...);
#     it takes ~25 minutes and runs only when dep manifests change.
#   - lockfile-audit.yml is a ~30 second pure-Python parse + grep on
#     the lockfiles themselves; it runs on every PR that even nudges
#     a lockfile so reviewers always see the audit result inline.
