The GoF catalog's four-dimensional behavioral modification space (wrapping depth, decoupling topology, state capture, state-strategy duality) extends beyond the behavioral pattern category into structural territory via the wrapping continuum — Proxy and Decorator are classified as structural yet participate in the wrapping depth axis alongside behavioral Strategy — revealing that the creational-structural-behavioral classification is a pedagogical convenience, not a hard architectural boundary for understanding modification mechanisms.
The four-dimensional modification space crosses the structural-behavioral classification boundary via the Proxy→Decorator→Strategy wrapping axis
