Marsaglia's XorShift (2003) --- three shift-xor operations per step. Fast and passes most tests, but fails binary rank and linear complexity
Standard analysis sees: rich, high-entropy values; high-complexity (noise-like); homoskedastic; high-dimensional / space-filling. The atlas finds no named structure, but the source is distinctively extreme on Zipf–Mandelbrot (8-bit):zipf_r_squared (-2.9z) — beyond what the standard bank predicts for it.
