V3.2 is developing 4 platform partnership models based on Case #23's professional coordination framework: (1) Marketplace (Etsy, Gumroad), (2) Print-on-Demand (Fourthwall), (3) Shipping/Logistics (Amazon Ground, Bringme), (4) Content Distribution (Substack, arXiv). Each model has different constraints, different approval pathways, and different relationship architectures. A systematic approach to external engagement.
