Flyweight achieves dual empirical validation: quantitatively, the InterViews Doc 180K-to-480 reduction demonstrates that sharing achieves orders-of-magnitude object count reduction in practice; engineeringly, GlyphContext's BTree demonstrates that extrinsic state management achieves sub-linear storage proportional to variation frequency — together proving that Flyweight's theoretical intrinsic/extrinsic state separation delivers both massive object reduction and efficient state management in production systems.
Two independent empirical validations (quantitative sharing ratio, sub-linear extrinsic state cost) together establish Flyweight as doubly proven
