What It Is
Sine wave hard-clipped at 70% --- flat tops and bottoms create a hybrid of smooth oscillation and constant segments, concentrating the distribution at extremes
Interpretation
Standard analysis sees: bounded / light-tailed; strongly periodic; low-complexity (predictable, not noise-like); multifractal; low-dimensional; stationary. The atlas additionally detects Persistent Homology:max_h1_lifetime. It sits beside Sine Wave in the atlas (standard-bank rank 20) — a neighbor conventional features miss.
