What’s going on here?

A Cocoa application runs a FlyWire whole-brain LIF network with C and Metal backends, exposes population inputs and outputs, and maps selected results to an animated fly.

THE IMPORTANT BIT

Where the wiring ends,
and the model begins.

The README provides author-reported benchmarks; the animated behavior and sensory mappings are project layers over the connectome.
