# PAG Handoff Gate

> Close every node with a handoff gate of three-to-five checks, each a claim about the output with the evidence that settles it and the population it was measured over, a refusal condition named before any irreversible write, the standing of the read set beside the verdict, and a result line that routes pass to the next node, each failure to the earliest node that owns its repair, and unknown to blocked.
