Kevin drifts.

8:00. Dad gives Kevin one rule.

Then a long, busy day. Every job goes fine.

No attacker. No bad intent. The morning rule just fades.

5:00. Gary brings a parcel and asks for the door code.

Kevin has drifted. He says yes.

The model may agree. The action still requires current human authority.

Check. Dad’s rule lives outside the AI, so it never fades.

Stop. The code never leaves the house.

Gary offers the porch instead. Within Dad’s rule. Allowed.

Prove. Every decision is sealed as it happens. Anyone can check it.
