20fly8

2048 learned in the browser by a FlyWire v783 mushroom-body model: each board cell and tile size drives its own projection neuron (32 of 267), the measured PN -> Kenyon-cell (27,502) and Kenyon-cell -> MBON (62,261) connections carry the smell to 96 output neurons, and approach vs avoidance is read from which dopamine cluster (PAM or PPL1) innervates each MBON. A project-defined dopamine rule driven by a reward-prediction error (TD learning on afterstates) changes only the Kenyon-cell -> MBON gains. Circuit subset; firing-rate model, not spikes. Reports frozen-synapse controls over 500 games: random moves 1,103, naive fly 1,594, trained after 3,000 games 6,986 (512 in 75%, 1024 in 15%), nose rewired 925, synapses shuffled 1,287.

The evidence

No evidence, no level.

Nothing filed yet. The description above is carried over from cobanov/awesome-fly and townie/awesome-fruit-fly, which is a source review — not an independent reproduction, and not enough on its own to earn a level.
