Status: OUT
PreorderIterator's stack-of-iterators implementation (each Composite node producing its iterator via CreateIterator factory method) concretely validates that creational patterns serve as enabling infrastructure for behavioral patterns within recursive structures — Factory Method is not merely a standalone creational choice but a structural integration mechanism binding the creational and behavioral aspects of recursive composition.
Factory Method within PreorderIterator proves creational-behavioral integration as a necessary aspect of compositional monism
