Fed. R. App. P. 1(a)(1). See Dooley v. Tice, No. 17-4315, 2019 WL 6771732, at *1 (E.D. Pa. Dec. 12, 2019) (Rule 10(e)(2)(B) permits a district court to correct an omission or misstatement of the district court record and forward a certified supplemental record for use on appeal and because movant's case remained pending in the district court, Rule 10(e)(2)(B) is inapplicable). The Commonwealth asks us to supplement the record under Rule 10(e)(2)(B) — after our March 24, 2021 final decision granting habeas relief to Mr. Gaines — to consider a voir dire transcript never produced to us.
