TraceError Where a deferred definition reaches itself, or the target is deferred and the definition it states doesn't narrow the target of the link it overrides
Resolves the resource shape a shape points at.
Crosses a reference to the shape it points at and takes a resource shape to itself, so that a caller reaching for the members behind a shape needs not tell a link from a resource carried inline. A shape describing a plain or localised value, or a union, points at no resource and yields nothing.
