Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

Performs the actual record resolution for a lazily-declared input.

Handles the decision logic: is the raw value already an instance, nil, an array, or a lookup value? Delegates to the appropriate finder method on the target class.
