What proof do you have that governance happened?

Assurance in most AI deployments is architectural description: the vendor explains what the system does. Nothing in that can be independently checked, which is why governance claims survive procurement and fail audit.

In Centralpoint the governance dictionary is versioned content, skills and prompts are records with owners and history, and the Interaction Log retains which rules loaded and what was retrieved for each execution. The proof and the mechanism are the same artefacts, so a claim about governance resolves to a query rather than to a diagram.
