A 668-neuron FlyWire v783 circuit (LC4/LPLC2 looming detectors, the Giant Fiber pair, DNa01/DNa02 steering, DNp09, DNg11, MDN and their strongest partners) with 18,968 real signed connection rows runs as a 1 kHz leaky integrate-and-fire simulation - 20 ms membrane tau via a 0.9512 per-ms decay, unit threshold, 2 ms refractory, delayed inhibition queue - plus a 1,045-neuron MaleCNS brain-to-leg extract driving articulated joints. Documented neuron dynamics on real connectivity is L1. Not L2: the weight array is filled once while building the CSR from the connectome file and is only read inside the propagation loop; a repository-wide grep for plasticity, STDP, dopamine or any learning rate returns nothing in the Swift or JS sources. EVALUATION.md states the locomotor upgrade does not add learning.
