What It Is

Bak-Tang-Wiesenfeld sandpile --- self-organized criticality produces power-law avalanche sizes without parameter tuning. Slow buildup with sudden cascading collapses

Interpretation

Standard analysis sees: right-skewed; aperiodic / broadband; homoskedastic; multifractal. The atlas finds no named structure, but the source is distinctively extreme on Attractor Reconstruction:lyap_sum (-4.0z) — beyond what the standard bank predicts for it. It sits beside Categorical Sensor in the atlas (standard-bank rank 33) — a neighbor conventional features miss.
