The GoF's recommended starter patterns (Abstract Factory, Factory Method, Adapter, Composite, Decorator, Observer, Strategy, Template Method) happen to include representatives from both behavioral subsystems of the empirically validated practitioner system — recursive structure (Composite, Decorator) and event-driven architecture (Observer, Strategy) — along with creational and structural bridging patterns. This overlap suggests the starter set may have been selected, at least in part, to introduce the system's dual behavioral infrastructure, though the antecedents do not establish that the selection was deliberately pedagogically structured to cover the system's full architectural breadth.
Starter patterns provide entry points across both behavioral subsystems plus supporting infrastructure
