What It Is
Wolfram Rule 30 center column --- produces output indistinguishable from random despite simple local rules. Used as Mathematica's default random generator
Interpretation
Standard analysis sees: bounded / light-tailed; few distinct values; monofractal; stationary. The atlas finds no named structure, but the source is distinctively extreme on S² × ℝ (Thurston):height_drift (+5.5z) — beyond what the standard bank predicts for it. It sits beside Symbolic Lorenz in the atlas (standard-bank rank 39) — a neighbor conventional features miss.
