Lower-Christoffel / Sturmian word of slope log2(3): the balanced binary sequence s_i = floor((i+1)d) - floor(i*d) with d = 1/(1+log2(3)) ~ 0.3868 (the 1-density). Like the Fibonacci Word it has minimal complexity p(n) = n+1 (the fewest distinct length-n blocks an aperiodic sequence can have), but its irrational slope is log2(3) --- the growth constant of the Collatz / 3n+1 map --- rather than the golden ratio, making it the symbolic cycle/parity word of that dynamics. Stationary and non-monotone. Included as a contrast to the golden-slope Fibonacci Word: is the log2(3) slope geometrically special, or just another minimal-complexity Sturmian?
Standard analysis sees: bounded / light-tailed; few distinct values; anti-correlated (alternating); anti-persistent; blue spectrum (high-frequency power); strongly periodic; homoskedastic; monofractal; stationary. The atlas finds no named structure, but the source is distinctively extreme on H3 Icosahedral:nn_enrichment (+4.1z) — beyond what the standard bank predicts for it.
