What It Is

Binary substitution sequence (0→01, 1→10) --- perfectly balanced yet aperiodic, with a singular-continuous, highly peaked Fourier spectrum (not flat like noise) despite being entirely deterministic

Interpretation

Standard analysis sees: bounded / light-tailed; few distinct values; anti-correlated (alternating); anti-persistent; blue spectrum (high-frequency power); monofractal; stationary. The atlas finds no named structure, but the source is distinctively extreme on H3 Icosahedral:temporal_coherence (+7.3z) — beyond what the standard bank predicts for it.
