  • Extend ValueTensorLiteral lowering so DenseResourceElementsAttr integers are rebuilt with signless element types before emitting tosa.const, matching the converted tensor type.
  • Add lit coverage for resource-backed i32/i64 vtensor literals.
  • Add FX importer e2e tests that return constant int32/int64 tensors.
