Field notes

The opponent is not a biological simulation: board features feed a fixed fly-derived spiking circuit, whose eight learned output weights select placements. The displayed checkpoint reports 256 neurons, 9,089 connections, 3.19 hours of training, and 63 generations. Its evaluation is presented with useful limits rather than just a victory claim: 24 paired games across eight sequences produced a 95% interval that includes zero, and the page says some sequences regress.
