The object identity spectrum (Prototype's fully independent copies through Flyweight's maximally shared instances) precisely bounds the sharing infrastructure that enables composition to scale: the efficiency gains of composition-based architectures (Flyweight's factory-managed sharing, Singleton's controlled access, cross-category reuse enablement) are constrained by where on this identity spectrum each object falls — full independence maximizes flexibility but wastes resources, while maximal sharing maximizes efficiency but constrains mutability.
The identity spectrum provides the design variable that determines whether the sharing infrastructure achieves its scalability targets
