Two machines. One floor. Every event accounted for.

A simulated ForgeSand D1 cuts the open field. It parks, and a simulated ForgeEdge E1 cuts the 12 cm band at the wall a drum physically cannot reach. They alternate once per grit, reporting pressure, dust and coverage the whole way — and the finished run hands the completion report field coverage and perimeter coverage as two figures, each attributed to the machine that earned it.
