Rating note

A 139,255-neuron FlyWire FAFB v783 simulation running the Shiu et al. (2024) whole-brain LIF model, transcribed constant-for-constant with an equivalence test against a literal Brian2 reference. Voltages evolve under a documented, published neuron model, so L1 is comfortably earned. Not L2: the engine's step() reads self.wdata to schedule delayed synaptic events but never writes to it, and the project's own assumptions document states plainly that there is no synaptic plasticity, facilitation, depression or adaptation, and that the mushroom body 'is present and wired, but cannot learn here'. The escape-circuit experiments work by silencing neurons, which is a lesion, not plasticity.
