Integrate-and-fire neuron model --- quiescent charging with sudden discharge spikes
Standard analysis sees: heavy-tailed; left-skewed; time-irreversible (slow rise, sharp collapse). The atlas finds no named structure, but the source is distinctively extreme on S² × ℝ (Thurston):height_drift (+2.5z) — beyond what the standard bank predicts for it. It sits beside Network Packet Sizes in the atlas (standard-bank rank 109) — a neighbor conventional features miss.
