Governance is where AI programmes actually stop, and it is usually answered with a picture of a shield. Here is the trace instead: one agent asking to touch a real system, and every gate between it and the record.
the request
Step 03 is the whole argument. The gate that stopped this call was written by one of your own people, doing their job, and it now applies to every agent, on every model, for as long as you run the layer.
Engineering declares the rails once. Nothing above them can reach past what was declared. Six gates, one call, fully traced.
Illustrative. The workflow, the rule and the person are invented to show the shape of the thing, not drawn from a customer.
