Status: IN
SOLID operates at a meta-level above the GoF's own classification while being demonstrably complete: its transcendence of Creational-Structural-Behavioral boundaries from both orthogonal axes (substitutability pipeline and cohesion pair) establishes its meta-level status, while its demonstrated completeness as a judgment system spanning the four-dimensional modification space establishes that this meta-level operation is comprehensive, not merely partial.
Transcendence establishes meta-level; demonstrated completeness establishes comprehensiveness at that level
