+"""Pre-migration for Express Orders (19.0.22.0.0).
+
+Runs BEFORE Odoo's field-registration pass on `-u fusion_plating_configurator`,
+so the model can register `terms_and_conditions` and `pricelist_id` against
+columns that already hold data.
+
+Actions:
+  1. Rename `fp_direct_order_wizard.notes` → `terms_and_conditions`.
+     Existing data preserves its semantic (always was customer-facing because
+     the old `action_create_order` wrote it to sale.order.note).
+  2. Add the new Express columns (idempotent — IF NOT EXISTS guards).
+  3. Backfill `pricelist_id` from the legacy `currency_id` via any active
+     pricelist matching the currency. After this, the model's stored-related
+     currency_id (related='pricelist_id.currency_id') takes over.
+  4. (No currency_id column drop here — Odoo's schema sync recognises the
+     related field and keeps the column shape; data refreshes from the
+     related lookup on subsequent writes.)
+
+Dev-stage caveat: per the Express Orders design spec section 12, we are
+ignoring past orders. If `currency_id` data on legacy rows doesn't line up
+with the new pricelist_id-driven flow, that's acceptable.
