Halvorsen x-coordinate --- 3-fold cyclically symmetric chaotic flow: each axis obeys the same equation with cyclic substitution. Topologically a 'cyclic transport' attractor, distinct from Lorenz switching or Rossler spiral.
Standard analysis sees: smooth / autocorrelated; red spectrum (low-frequency / 1-over-f power); low-complexity (predictable, not noise-like); time-irreversible (slow rise, sharp collapse); volatility-clustering (bursty). The atlas detects no named structure beyond this.
Nothing beyond the standard reading — this source’s structure is already captured by standard features; the atlas adds no named residual.
