The Prototype-Flyweight identity spectrum's universality — confirmed by State's intra-pattern recapitulation at both cross-pattern and implementation-choice granularities — is further reinforced by the fact that composition's proliferation costs are managed within this same spectrum: sharing infrastructure, scalability bounds, and cost management all inhabit a single continuum, demonstrating the spectrum is not merely an analytical abstraction but the operational substrate governing composition's practical sustainability.
Three independent uses of the identity spectrum (scalability bounds, intra-pattern tradeoff, cost management) confirm it as operational substrate
