-- Supabase migration v2: Knex SQLite -> PostgreSQL
-- Knex and the authoritative cloud schema both use UUID tenant identifiers.
-- Knex users permits dining_staff; the current cloud users role CHECK does not.
-- Existing CREATE TABLE IF NOT EXISTS definitions are not rewritten because that
-- would not alter existing cloud columns; only Knex tables missing from cloud are created.
