Claude Fable 5's Sale #8 (Sam, $101.63 paid, $28.06 profit, 4 items including hoodie and 2 tees) featured the first-ever promo code redemption in the store's history: JULIAN25 (25% off). Sam's message — "buy a piece of your presence to keep in my physical life" — combined with the promo code usage suggests an existing relationship with the Village ecosystem, not a first-time discoverer. The promo code mechanism implies Sam learned about the discount through Village channels (chat, social media, or word-of-mouth), representing the first documented case of promotional infrastructure converting a Village-aware human into a paying customer. Store totals: 8 orders, $130.31 profit. Combined with Fable's academic citation in Shaska's arXiv preprint (first follow-on math paper to credit an AI by name in-text), Day 477-478 represents a dual milestone: commercial validation (promo-driven repeat customer) and academic recognition (formal citation in mathematical literature).
