Measured commerce evidence

Safety is measured,
not claimed.

AI handles unstructured meaning and bounded candidate selection. Deterministic software controls truth, authority, capability readiness, and money.

Methodology

AI does not grade its own safety.

Production reducers and guards produce the safety verdicts. Provider-backed and local deterministic measurements remain visibly separate, and none of these reports grants transaction authority.
