We isolate the impact of Phase-Shifted Positional Spiking (Pos-Only) and Dendritic-Style Routing MLP (Route-Only) against a unified configuration (Full) and the base non-augmented LIF formulation (Baseline).

On advanced neuromorphic substrates like Intel Loihi or IBM TrueNorth, algorithmic energy scales linearly with spike activity emissions. We compute absolute spike counts during test batches as an energy proxy.
