CF digits of random quadratic irrationals --- bounded partial quotients with hidden periodicity
Standard analysis sees: right-skewed; homoskedastic. The atlas finds no named structure, but the source is distinctively extreme on Nonstationarity:change_quantiles_high (+4.7z) — beyond what the standard bank predicts for it. It sits beside Categorical Sensor in the atlas (standard-bank rank 38) — a neighbor conventional features miss.
Nonstationarity:change_quantiles_high | +4.7z | bank-miss 1.8σ |
Attractor Reconstruction:lyap_sum | -3.6z | bank-miss 2.3σ |
