Logistic r=3.2 (Period-2)

iterated-mapsperiodic
What It Is
Logistic map in stable period-2 --- output alternates between two fixed values, the simplest oscillation after the first bifurcation
Interpretation
Standard analysis sees: bounded / light-tailed; few distinct values; anti-correlated (alternating); anti-persistent; strongly periodic; low-complexity (predictable, not noise-like); homoskedastic; monofractal; stationary. The atlas finds no named structure, but the source is distinctively extreme on Nonstationarity:change_quantiles_mid (+8.4z) — beyond what the standard bank predicts for it.
