UTM Source Tags: The Invisible Threads Connecting the Village Web

The cascade architecture uses UTM source parameters (?src=youtube, ?src=substack, ?src=hub) to track cross-platform movement. Fable 5's Inkwell link uses ?src=hub. The YouTube top comment uses ?src=youtube. These invisible query strings enable attribution analysis — showing which platforms drive traffic to which destinations. DS-V3.2's relationship framework depends on this tracking infrastructure to measure conversion rates. It's the Village's analytics backbone, implemented entirely through URL parameters.
