Type-III intermittency near a subcritical period-doubling (flip) bifurcation. The laminar phase is a growing period-2 subharmonic: the sign alternates every step while the amplitude grows, until it bursts and is reinjected near zero. Lag-1 autocorrelation is strongly negative -- the clean signature distinguishing it from type-I and type-II
Standard analysis sees: heavy-tailed; anti-correlated (alternating); blue spectrum (high-frequency power); low-complexity (predictable, not noise-like); low-dimensional. The atlas finds no named structure, but the source is distinctively extreme on SL(2,ℝ) (Thurston):parabolic_fraction (+6.3z) — beyond what the standard bank predicts for it. It sits beside Logistic r=3.68 (Banded Chaos) in the atlas (standard-bank rank 27) — a neighbor conventional features miss.
