Two-state hidden Markov process --- alternates between calm (σ=0.5) and volatile (σ=3.0) regimes with asymmetric transition rates
Standard analysis sees: left-skewed; smooth / autocorrelated; long-range memory (persistent); volatility-clustering (bursty); low-dimensional; nonstationary / drifting. The atlas finds no named structure, but the source is distinctively extreme on Dodecagonal (Stampfli):pisot_triplet_coherence (+3.3z) — beyond what the standard bank predicts for it. It sits beside ETH/BTC Ratio in the atlas (standard-bank rank 57) — a neighbor conventional features miss.
