MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).

• Potentially malicious external URL detected (high risk: 0.90). The scheduled GitHub Actions workflow in references/ci-quarantine-report.md uses the remote action "actions/checkout@v5", which is fetched and executed at runtime by the CI runner (remote code execution), so it is a runtime external dependency the skill relies on.
