Within the compositionally monistic design system, inheritance serves two independently characterized architectural roles: Template Method provides the principled bridge between inheritance and composition for algorithm customization, while Visitor's dual class hierarchy employs inheritance to achieve type-governed recursive extensibility via double dispatch — two distinct capabilities that inheritance enables which composition alone cannot replicate, justifying inheritance's bounded role within the monistic system.
Template Method bridging and Visitor type governance represent inheritance's two independently necessary roles within compositional monism
