Status: IN
The validated SOLID design system is governed by coupling management and classification evidence (composition dominates via runtime flexibility), while patterns systematically migrate across the GoF's own classification boundaries — the system remains governable precisely because SOLID's governance operates above the permeable classification, not through it.
Classification permeability is safely governed because SOLID operates above the classification that patterns cross
