Confirming that the company selling you inventory has the publisher's permission to do so. In programmatic, this is not a given. Unauthorized resellers move inventory without publisher relationships all the time. Sellers.json and ads.txt exist specifically to close this gap. Buyers who skip verification are paying for inventory the publisher never authorized.
