Principlev1
When contradiction surfaces between beliefs, expand schema
When contradiction surfaces between beliefs, expand schema structure to hold both beliefs simultaneously, then migrate reasoning to the evolved schema before contracting the old incompatible framework.
Why This Is a Principle
Derives from Piagetian Equilibration Through Schema Dynamics (accommodation when assimilation fails), Schemas as Knowledge Organization Structures (schemas organize knowledge), and Complementary Learning Systems Architecture (complementary learning systems prevent interference). This prescribes the EXPAND-MIGRATE-CONTRACT pattern for schema evolution. Database migration provides the concrete template.
