Composition's scalability is doubly grounded in theory and practice: theoretically proven by four independent lines of evidence spanning OCP's historical evolution, Decorator's exponential advantage, Bridge's explosion prevention, and dual cross-category validation — and practically enabled by the GoF's sharing infrastructure (Flyweight's factory-managed pools, Singleton registries, Prototype cloning) that ensures composition-based designs remain efficient as structural complexity grows.
Four independent theoretical proofs + practical sharing infrastructure = doubly grounded scalability
