Status: IN
Pluggable Adapter's three implementation approaches and Abstract Factory's three implementation techniques independently recapitulate the identical three-mechanism reuse spectrum (inheritance → composition → parameterized types), providing convergent validation that the spectrum is exhaustive: two unrelated patterns from different GoF categories arriving at the same three alternatives independently is strong evidence for the taxonomy's completeness rather than an artifact of any single pattern's design constraints.
Two independent patterns from different categories recapitulating identical reuse spectra convergently validates the taxonomy
