flybrain (MaleCNS pong-catch)

A ball-catching paddle driven by 4,706 MaleCNS neurons on a sensory-to-descending path (306k edges, sign from consensus neurotransmitter). Every synapse stays frozen anatomy; only a linear readout over descending-neuron rates is trained by the cross-entropy method. Chance is 33%; reading out the connectome alone reaches 54%, and a champion-restart refinement climbs to 84.4% on held-out seeds. The README also lists what failed: dopamine/RPE plasticity, elitist CEM, cross-seed weight averaging, and subsampling the circuit below about 3k neurons.
