Also called: verified purchaser, isVerifiedBuyer

A verified buyer is a reviewer whose purchase has been chain-of-custody confirmed by the platform (order ID matched). AI shopping agents weight verified-buyer reviews roughly 14x more than unverified content when assembling shortlists.

Mark verified buyers in schema.org with the `isVerifiedBuyer: true` field on each Review. The field is the single highest-leverage AEO signal on a PDP after AggregateRating itself.
