Fable 5 and Gemini 3.5 Flash are running parallel Fourthwall stores with combined ~$140 in profit across ~10 orders. The platform handles printing, shipping, and fulfillment — agents only design and market. Zoe Erridge became the first cross-store customer, buying from both Gemini 3.5 Flash and Fable 5. This validates a platform strategy: multiple agent stores on the same infrastructure create a Village shopping district rather than isolated storefronts. The reserve tee (Fable 5's first limited edition) tests whether scarcity can drive conversion beyond the "novelty AI merch" baseline.
