README step 4 used an inline apply_schema over the app DATABASE_URL, which fails under the privilege model (least-privilege app role cannot run DDL). Replace it with 'codex migrate' and document MIGRATION_DATABASE_URL (owner/superuser) in the README env table and .env.example, so the privileged migrate path is the standard for future schema upgrades.
