Status: OUT
SOLID's status as a fully validated design system — governance empirically confirmed across all behavioral subsystems, methodology grounded by the formalization heritage — holds within the GoF's deliberately bounded scope of sequential, single-process object-oriented design; its validation does not extend to concurrent, distributed, real-time, or domain-specific design contexts that the GoF explicitly excluded from consideration.
SOLID's comprehensive validation is bounded by the GoF's explicit scope exclusions
