Execution budget of the concrete powered-row field plan

The cost is the sum of the actual relation and endpoint-comparison transition counts. Each fixed command scans only the serialized input graph. The execution certificates below instantiate the concrete plan trace; no execution witness or running-time bound is assumed.
