What It Is
Type-II intermittency near a subcritical Neimark-Sacker (Hopf) bifurcation. The laminar phase is a slow spiral: a rotation whose amplitude grows smoothly until it leaves the channel, bursts, and is reinjected near zero. Distinct from Pomeau-Manneville type-I (tangent bifurcation) and type-III (period-doubling); laminar length scales as epsilon^-1
Interpretation
Standard analysis sees: heavy-tailed. The atlas finds no named structure, but the source is distinctively extreme on Ordinal Partition:memory_order (+4.8z) — beyond what the standard bank predicts for it. It sits beside Bearing Inner in the atlas (standard-bank rank 48) — a neighbor conventional features miss.
