What's Changed

• Detection capabilities have been upgraded to better recognize attempts at runner tampering. These improvements are informed by real-world incident learnings, including analysis of anomalous behaviors observed in the tj-actions and reviewdog supply chain attack.
• Resolved an issue where the block policy was not enforced correctly when the GitHub Actions job was running inside a container on a self-hosted VM runner.
