Status: OUT
Decorator occupies a confirmed niche in the wrapping taxonomy — validated as the composition-based responsibility-augmentation mechanism differentiated from Adapter's interface conversion and Composite's structural aggregation, and positioned on the wrapping depth axis between Proxy's access control and Strategy's algorithm replacement — but this niche is operationally bounded: a decorated component is not identical to the original, and composition order affects behavior, constraining deployment in identity-sensitive contexts.
Decorator's taxonomic position is well-defined but practical deployment is constrained by identity semantics that break transparent substitution
