Second reading, downgraded from a proposed L2 for consistency. The plastic arm is the real thing and nothing here disputes it: a dopamine-gated, baseline-centred anti-Hebbian rule over ~7,835 KC→MBON07/MBON11 edges, with PAM11 and PPL101 compartments and gains derived from anatomical DAN→MBON contact counts, where the dopamine term is the compartment’s own measured firing rate rather than an injected scalar. But it is off by default (neural.plastic is False), so a stock run is a frozen graph plus a fitted readout. The site rates what a default run does — a rule anyone can check by cloning and running — and notes the arm that ships disabled. Turn it on and this is L2. L1 stands on the event-driven LIF kernel (tau_m 20 ms, tau_s 5 ms, threshold −45 mV, rest −52 mV, 2.2 ms refractory).
