Evidence Quality
Primary source — official Microsoft open-source GitHub repository. Public-preview state (may have breaking changes before GA). Installing any framework integrations or policy engine components from PyPI/npm/NuGet should be done with normal supply-chain hygiene (verify package hashes, review code).
Follow-Up
- Add as a related control from existing hardening/detection/agentic AI entries
- Cross-link with any OWASP Agentic Top 10 or NIST AI RMF entries
- Monitor for production GA release and updates to coverage claims
