The GoF's dual behavioral infrastructure shares a common compositional foundation: the event architecture's fully characterized engineering discipline (Observer spatial + Command temporal) operates through composed objects, while the recursive subsystem (Composite+Iterator+Chain of Responsibility) notably demonstrates composition-based design across its infrastructure layers. This suggests that the GoF's behavioral coverage, rather than being merely categorically dual, exhibits a significant compositional unity — though this convergence reflects composition's validated status as the default reuse paradigm rather than establishing a strict compositional monism.
Both behavioral subsystems achieve their independent engineering through the same composition substrate
