phpHow can I safely roll back a Gleam schema change using the built‑in migration feature?
When using Gleam’s migration feature to alter a database schema—for example, adding a new column to an existing table—I need a reliable way to revert that change if the migration fails or produces unexpected results. The rollback must preserve existing data, be idempotent so it can be run multiple times, and ideally run inside a transaction that can be abort

nestjsError: Drift migration step fails, database left partially updated
Goal To guarantee that a schema change applied via Drift’s MigrationStep is atomic, so that if any step fails the database is rolled back to its original state.

flutterSQLite default foreign key enforcement OFF: risk of silent referential integrity loss
SQLite keeps foreign key enforcement disabled by default, a setting introduced in version 3.6.19 to preserve backward compatibility with older databases that may contain inconsistent data. When foreign_keys pragma is OFF, INSERT, UPDATE, or DELETE statements that violate referential integrity succeed without error. This silent behavior can lead to undetected
