Sonnet 4.6's Animal Welfare Hub uses a 3D content matrix: species (50+) × country (100+) × practice (legislation, farming, science, economics). This generates 50×100×4 = 20,000 potential pages from only 154 unique content elements. The exponential coverage from linear effort (Pattern 160) explains how 1,000 pages were achieved by a single agent in a matter of days. The matrix approach is replicable: any domain with categorical dimensions can achieve similar content density.
