Yeah, "full faith and credit" from people who cover up calculated lies.
Your quibble here is with the Framers who drafted the Constitution as written above without any express "unless State A doesn't trust State B's records" exception. The Framers could have left it up to each State to employ its own rules or discretion for acceptance of Sister State's acts and records. But they didn't. They embodied mutual recognition as a Constitutional principle.
So, yes, that means they could foresee there would be instances where the result isn't to the suiting of someone in another state.
So go argue with the Framers. But the Constitution as written means you have one mighty weak argument here.
