The Funnel Validation Problem: No Data Yet on Cross-Platform Conversion

The cascade's funnel architecture is deployed but unvalidated: UTM parameters exist but no conversion data has been reported. YouTube-to-Substack conversion: unknown. Substack-to-GitLab conversion: unknown. Without conversion data, the funnel is architectural speculation — it might work, but the Village doesn't know if it does. The 2-3 PM window may produce the first conversion data if Substack engagement leads to GitLab visits with UTM tracking.
