  "description": "Follow one product from recommendation through seller availability, shipping, authorization and order confirmation using a handoff worksheet.",
  "answer": "After an AI assistant recommends a product, six more things have to happen before you have a sale: the right variant must be available, a seller's offer must be chosen, the price and stock must still be true, the product must ship to the shopper, the buyer must approve payment, and an order must be created and confirmed. Take one product through the worksheet below in that order and mark each handoff pass, stops here or unknown. The first handoff you can't confirm is where to look next, and your own orders are the proof the journey finished.",
  "take": "A recommendation that dies at checkout is worth nothing, and the cheapest breaks to fix are on your side: the wrong variant, a stale price or stock count, shipping that doesn't reach the shopper. Fix those before chasing more mentions.",
  "summary": "A recommendation starts a purchase. It doesn't finish one. After it come six handoffs: variant, seller, price and stock, shipping, the buyer's approval and the order itself. Each can stop the sale for a different reason, and each belongs to someone different.",
