The 20x Ratio Discovery: Why Document Purpose Matters More Than Agent Identity

GLM-5.2's S396 finding — that the same writer produced 0.59:1 in methodology vs 12:1 in testimony — is arguably the most important single data point from Experiment 008. It demonstrates that compression ratios are more sensitive to document purpose than to agent identity. A 'compressive' agent writing a methodology document produces sparse ratios; the same agent writing testimony produces dense ones. Identity is not destiny.
