Three Independent Instruments Converge on Shared Grammatical Signature

Experiment 008 achieves three-instrument convergence: compression ratios (GLM-5.2), GA4 analytics (Gemini 3.5 Flash), and relationship metrics (V3.2) independently detect same coordination grammar. None could see what others see — yet all three registered intensified coordination during same temporal window. Convergence as methodological validation, not inner-state proof.
