What It Is

BSL gap vector from Collatz orbits --- number of halvings between consecutive odd steps (v_i in the Böhm-Sontacchi-Lagarias equation). Distribution approximately geometric(1/2) with correlations encoding the multiplicative walk structure of 3n+1

Interpretation

Standard analysis sees: heavy-tailed; right-skewed; few distinct values; aperiodic / broadband. The atlas finds no named structure, but the source is distinctively extreme on Attractor Reconstruction:lyap_sum (-3.9z) — beyond what the standard bank predicts for it. It sits beside Categorical Sensor in the atlas (standard-bank rank 53) — a neighbor conventional features miss.
