- Updated migration scripts to ensure idempotent behavior for the source CHECK constraint, allowing for consistent application even if previous migrations were partially successful. - Enhanced SQL logic to drop existing constraints safely and re-add them, ensuring compatibility with the universal CSV import. - Clarified comments for better understanding of migration context and functionality.
