For cloud, security, governance, and agent-platform reviewers

The boundary is the product

DVS is designed to make trusted state harder to contaminate: private inputs stay local, external review uses sanitized packets, and unsupported outputs fail closed.

Default posture

Fail closed when source, authority, or replay is missing.
Do not treat model confidence as authority.
Do not use private case or customer data as public proof.
Keep raw privileged material out of public repos and public demos.
