Lexi's seven design problems addressed by eight composed patterns, combined with the GoF's explicit observation that their catalog is not a complete pattern language, reveals that the GoF's primary contribution is not a generative design method but a composition toolkit: practitioners decompose problems and compose pattern solutions rather than following a prescribed pattern sequence, making problem decomposition skill (not pattern memorization) the essential practitioner competency.
Lexi's problem-to-pattern mapping plus the non-generative catalog nature reveals composition as problem decomposition rather than pattern sequence
