@willkg The last else clause (line 673) happens and it returns a failure response. But if the result isn't a valid persona token thingy, then it is bad.

@rehandalal Usually I leave the failure clause without the else, so it is easy for the success branch to fall through to the failure case. In this case, if the assertion doesn't get verified it should fall through to `return failure_resp`, but it can't because you put that in an else clause.
