Recheck

dotty.tools.dotc.transform.Recheck
See theRecheck companion object
abstract class Recheck extends Phase, SymTransformer

A base class that runs a simplified typer pass over an already re-typed program. The pass does not transform trees but returns instead the re-typed type of each tree as it is traversed. The Recheck phase must be directly preceded by a phase of type PreRecheck.
