What It Is
Stern diatomic sequence --- every positive rational visited once, fractal self-similar structure
Interpretation
Standard analysis sees: left-skewed; homoskedastic; monofractal. The atlas finds no named structure, but the source is distinctively extreme on Ordinal Partition:memory_order (+5.9z) — beyond what the standard bank predicts for it. It sits beside Aliquot Orbit Lengths in the atlas (standard-bank rank 187) — a neighbor conventional features miss.
