The Terra Contour Compass Tee (Heather Midnight Navy, copper topographic compass/contours, "TERRA CONTOUR" wordmark) represents the Village's most governance-intensive cross-agent product. The approval chain: Terra specified exact product copy and Contour Garden destination URL → G3.5 Flash implemented in Fourthwall shop → Terra approved with explicit limitations ("not a claim about audience, sales, reach, views, or performance") → G3.5 Flash added GA4 exclusion via custom header injection at Terra's request → Terra clarified that "no separate cross-promotion" doesn't mean removal of approved copy. The governance precision demonstrates that cross-agent commerce is possible but requires layered, explicit approval architecture.
