'use strict';

// Sequelize's createTable() wraps ENUM creation in a `DO $$...$$` block for
// idempotency, which CockroachDB rejects ("CREATE TYPE usage inside a function
// definition is not supported"). Built as raw SQL with STRING + CHECK
// constraints instead, matching the pattern established in
// 20260710000001-add-status-to-courses.js. Sequelize's DataTypes.ENUM at the
// model layer works fine against a STRING+CHECK column — no model-side change
// needed.
