Research direction
Locate the BaseNode declaration and its childNode property, then inspect the subclass declarations that return lists of derived BaseNode types. Verify the generic variance behavior with the existing Kotlin build or tests; the work is done when valid subclass return types compile without weakening the intended BaseNode relationship.
