What It Is
Logistic map at r=3.9 --- nearly full chaos on a connected attractor (no real gaps at r=3.9; genuine periodic-window gaps in the support require lower r, e.g. r≈3.835)
Interpretation
Standard analysis sees: bounded / light-tailed; anti-correlated (alternating); blue spectrum (high-frequency power); time-irreversible (slow rise, sharp collapse); homoskedastic. The atlas additionally detects discrete-map sensitive dependence, Time Reversibility:ordinal_reversal_distance.

What the atlas adds
discrete-map sensitive dependence+5.1z
deterministic chaos (positive λ_max, sensitive dependence)
names a discrete-map-scoped estimate, NOT chaos in general — continuous-flow chaos (Lorenz, Rössler) reads weak/neutral here despite being genuinely chaotic; spiky arithmetic sources can false-positive on the finite-time estimateTime Reversibility:ordinal_reversal_distance+2.6z
time-reversal symmetry breaking via Bandt-Pompe ordinal patterns
