Random piecewise-constant signal --- flat plateaus of random height with geometrically-distributed durations, creating a sparse derivative and blocky texture
Standard analysis sees: low-complexity (predictable, not noise-like); multifractal. The atlas finds no named structure, but the source is distinctively extreme on D4 Triality:edge_ortho_polarity (-4.7z) — beyond what the standard bank predicts for it. It sits beside Tank Drain Cascade in the atlas (standard-bank rank 36) — a neighbor conventional features miss.
