What It Is
Partial sums of the Rudin-Shapiro ±1 sequence --- a deterministic random walk (the flat-spectrum property belongs to the ±1 increments; the emitted partial-sum walk is red, ~1/f²)
Interpretation
Standard analysis sees: smooth / autocorrelated; long-range memory (persistent); volatility-clustering (bursty). The atlas additionally detects Nonstationarity:adf_pvalue.
