# This workflow uses actions that are not certified by GitHub.

# documentation.

# OSV-Scanner for detecting vulnerabilities in dependencies.
# Runs on PRs to catch vulnerable dependencies before merge (shift-left security).
#
# NOTE: This workflow is NOT included in release-gate.yml because
# GitHub Actions limits reusable workflow nesting to 2 levels. Since this
# workflow calls google/osv-scanner-reusable.yml, including it in the gate
# would create 4 levels of nesting and cause startup_failure:
#   release.yml → release-gate.yml → osv-scanner.yml → google/osv-scanner-reusable.yml
#
# For more examples and options, including how to ignore specific vulnerabilities,
# see https://google.github.io/osv-scanner/github-action/

# killed in-progress PR runs before they produced useful results.
# Future iteration could safely add concurrency for scheduled/push-only
# triggers (where head_ref is empty and runs get unique groups).
