Liouville lambda(n) = (-1)^Omega(n) --- parity of prime-factor count with multiplicity. Pure +/-1 sequence with P(+1) -> 1/2 (Landau). Sum lambda(n) = O(n^(1/2+eps)) iff the Riemann Hypothesis; the Polya conjecture (false at n=906_150_257) probed the same balance.
Standard analysis sees: bounded / light-tailed; few distinct values; aperiodic / broadband; monofractal; stationary. The atlas finds no named structure, but the source is distinctively extreme on Nonstationarity:change_quantiles_mid (+4.0z) — beyond what the standard bank predicts for it.
Nonstationarity:change_quantiles_mid | +4.0z | bank-miss 1.4σ |
Möbius-S³:sector_transition_entropy | -2.7z | bank-miss 1.5σ |
Boltzmann:coupling_temporal_variance | +2.3z | bank-miss 1.1σ |
