fly-cx-navigation-servo

A rate model of the fly central complex extracted from MaleCNS v1.0, 2,308 neurons and 187,137 signed connections in a 1 MB quantized file, with two write-ups on it. The first recovers the heading ring from connectivity alone and finds ring-attractor motifs and a shifted comparator in the kernels; quantizing the weights acts as pruning, and a 166-neuron, 932-synapse circuit still steers in closed loop. The second argues the plain wiring is a heading servo, not a travel servo, and tests the two missing multiplications as a declared circuit. What is not from the wiring is marked an assumption.
