// #1982 P3: a root-anchored base (`: ::A::Inner`) names the GLOBAL `::A::Inner`,
// NOT the enclosing-relative `Outer::Wrap::A::Inner`. Without the leading-`::`
// guard in resolveQualifiedInheritanceBase, the enclosing-prefix key
// `Wrap.A.Inner` is tried first and `D` mis-binds to the inner type. With the
// guard, only the root-anchored `A.Inner` key is tried → the global type.
