GlyphContext's BTree mapping (storage proportional to font changes, not characters) is a concrete engineering validation of Flyweight's intrinsic/extrinsic state separation: the BTree demonstrates that extrinsic state management can be made proportional to variation frequency rather than element count, proving that the theoretical state-splitting achieves practical sub-linear storage costs.
GlyphContext's BTree provides concrete empirical proof that extrinsic state management achieves sub-linear scaling
