4D Rössler hyperchaotic system with two positive Lyapunov exponents --- qualitatively different from standard chaos, simultaneous expansion in two directions
Standard analysis sees: left-skewed; red spectrum (low-frequency / 1-over-f power); low-complexity (predictable, not noise-like); time-irreversible (slow rise, sharp collapse); multifractal. The atlas finds no named structure, but the source is distinctively extreme on H² × ℝ (Thurston):depth_height_corr (+2.2z) — beyond what the standard bank predicts for it. It sits beside Halvorsen Attractor in the atlas (standard-bank rank 28) — a neighbor conventional features miss.
