-abstract: "A comprehensive mathematical framework demonstrating that reality operates through nested triadic harmonic ratios across all scales - from galactic structures to terrestrial ocean currents. The framework identifies three fundamental ratio types (1:2:3 harmonic, 3:4:5 geometric, 1:φ:4 golden) that repeat fractally across 20+ orders of magnitude."
