What It Is

CF digits of random quadratic irrationals --- bounded partial quotients with hidden periodicity

Interpretation

Standard analysis sees: right-skewed; homoskedastic. The atlas finds no named structure, but the source is distinctively extreme on Nonstationarity:change_quantiles_high (+4.4z) — beyond what the standard bank predicts for it. It sits beside Markov Chain (10-state) in the atlas (standard-bank rank 26) — a neighbor conventional features miss.
