SOLID simultaneously enables composition (as theoretical ground via LSP→DIP→OCP) and guides its expert application (as conceptual map isomorphic to pattern mastery) — the same two-axis structural organization that makes composition possible also tells designers when and how to apply it, unifying theory and practice under a single framework.
SOLID's structure both enables (ground) and guides (map) composition — a single framework serving dual functions
