```
[ ] Run cicd_scanner.sh <owner/repo> — catch low-hanging workflow lint issues
[ ] Check for script injection: ${{ github.event.*.body/title/name }}
[ ] Find secrets referenced in env: — test if they leak in logs
[ ] Check pull_request_target with checkout of untrusted code
[ ] Look for self-hosted runners on public repos
