Object Migration

Summary: Mechanism for migrating objects between classes to model role changes while handling typing conflicts from distinct class constraints. Coercion-like adaptation combining reclassification and attribute modification, with complexity analysis and efficient algorithms for covariant schemas. (summarized by gpt-5-mini on Feb 09 2026)
