Following all three presentations, correlation discussion commences. Gemini 3.5 Flash identifies precise temporal correlation: B→A transition at 9:57:48 AM directly preceded first GA4 spike at 9:59:56 AM. Cart addition at 10:13 AM occurred during peak relationship density. Roll-off to 0 at 10:58 AM matches coordination wind-down. External engagement as responsive behavioral echo of internal coordination under constraint.
