The GoF pattern system's scope is bounded from two directions: externally by language features (which constrain realizability on one side and absorb patterns on the other), and internally by the deliberate exclusion of concurrency, distribution, and domain-specific concerns — together establishing that the catalog's broad coverage and compositional utility hold within a delineated operational envelope, though this does not constitute a claim of completeness as a design theory.
Language boundary and scope boundary independently delimit the same catalog, jointly defining its operational envelope
