The three-mechanism reuse spectrum (inheritance, composition, parameterized types) achieves dual epistemic validation: convergently, two unrelated patterns from different GoF categories (Pluggable Adapter and Abstract Factory) independently recapitulate the identical three-mechanism spectrum; monistically, the spectrum is practically instantiated at the finest granularity within the compositionally monistic system, with a single adaptation problem naturally mapping onto all three mechanisms — establishing the spectrum as both taxonomically exhaustive and operationally real.
Convergent validation (two categories) and monistic confirmation (finest granularity) establish the reuse spectrum's dual epistemic status
