SOLID's dependency chain (LSP→DIP→OCP) provides the theoretical foundation that makes the GoF catalog's composition-centric paradigm possible — substitutability validates abstraction dependence, which enables extension without modification, which justifies the pervasive preference for composition over inheritance.
SOLID theory (depth-3) enables the GoF composition convergence (depth-3), unifying the theoretical and practical pillars of OO design at the highest level
