What is the test for a motion to vacate, set aside or correct a sentence under section 2255 of the Criminal Code?

"Pursuant to 2255, a federal prisoner may move to vacate, set aside, or correct his sentence on four grounds: (1) that the sentence was imposed in violation of the Constitution or laws of the United States, or (2) that the court was without jurisdiction to impose such sentence, or (3) that the sentence was in excess of the maximum authorized by law, or (4) is otherwise subject to collateral attack." United States v. Hoskins, 905 F.3d 97, 102 (2d Cir. 2018) (internal quotation marks and brackets omitted). Our Court has repeatedly held "that the scope of review on a 2255 motion should be narrowly limited in order to preserve the finality of criminal sentences and to effect the efficient allocation of judicial resources." Graziano v. United States, 83 F.3d 587, 590
