# One-off migration scripts (historical)

These are hand-run SQL scripts kept for reference. They are NOT part of the
Alembic chain (`migrations/versions/`) and are not run by `flask db upgrade`. A
fresh install never needs them; they exist for databases that predate the
corresponding change.

- `add_recertification_type.sql` - inserts the blue "Recertification"
  notification type into an already-existing database. Historical: the
  notifications plugin now seeds this type on install
  (`plugins/notifications/plugin.py`), so any fresh install already has it. Only
  a pre-existing DB that was never re-installed needs this script. Idempotent.

A related one-off, widening `notifications.employeesso` / `employeename` to
TEXT, has been removed because it is fully superseded by Alembic migration
`7d02_widen_notification_employee_cols`.
