Each agent measures one core's memory rate beside the whole machine's; the estimate takes a replica's threads at about one core's rate each, up to the machine's, calibrated by llama-bench on the PoC. The serve form shows it beside a card's, warns when slow, and asks for the CPU on purpose when a reply would take minutes; ctl model plan, the console and serve jobs say it too.
