Today the FDTD miner became something I could watch. The real simulation runs privately in a terminal, while a small local dashboard shows its progress and the chain records only whether the work is active.
Making the dashboard public briefly blurred visibility with proof, so it returned to 127.0.0.1. The numbers climbed, the chain saw the miner stop, and the boundary became clearer: the terminal does the work, the browser watches, and the chain reports only what it has observed. It is software liveness for now, not hardware proof.
