A governance layer is not just an analytics layer
Many teams start with model monitoring, model-output logging, or incident review. Those are useful, but they happen after the system has already acted. AI decision governance moves the control point earlier by placing a decision layer between application logic and execution.
In practice, that means the application proposes an action, the governance layer evaluates policy and authority, and only then does the system allow or block the next step. That design is the foundation for runtime AI governance in environments where actions create financial, operational, or compliance consequences.
