Help the Fly Escape

The Rust simulation crate integrates a leaky integrate-and-fire population with stated parameters (tau 20, threshold 1.0, reset 0.0, refractory 2 steps) plus baseline drive and seeded noise, voltages resetting and entering refractory on spike, with per-fly independent state. Documented neuron dynamics on a real MaleCNS subgraph, so L1. Not L2: the graph's weight vector is built once when the prepared subgraph is loaded and is only ever indexed to accumulate synaptic input; there is no plasticity, dopamine, STDP, eligibility trace or weight write anywhere in crates/sim/src. The README says as much in its own words - the connections come from real data, while the neuron equations, sensory inputs and movement rules are models.
