The wrapping depth axis (Proxy→Decorator→Strategy) crosses the GoF's structural-behavioral classification boundary: Proxy and Decorator are structural patterns providing access control and responsibility addition, while Strategy is a behavioral pattern providing algorithm replacement — revealing that structural and behavioral categories form a continuum rather than a partition along the modification-depth dimension.
Structural patterns classify Proxy/Decorator as wrapping patterns; the wrapping taxonomy extends the same axis into behavioral territory (Strategy), so the GoF category boundary is porous
