Task 2: Idempotent backfill script (migrate-services.ts) - Migrates service_catalog (21 rows) → services with migrated_from='service_catalog' - Migrates offer_services (35 rows) → services with migrated_from='offer_services' - Name collision detection: appends ' (Offer)' suffix to prevent overwrites - Idempotent via (migrated_from, migrated_id) lookups — re-runs are safe no-ops - Categorizes services: 'catalog' for operational pricing, 'offer' for marketing pricing - Maps service_catalog.description → services.description - Maps offer_services.transformation_description → services.description - Maps service_catalog.unit_price → services.unit_price - Maps offer_services.price → services.unit_price Task 3: Validation script (validate-services-migration.ts) - Check 1: Row counts match (service_catalog/offer_services rows == migrated rows) - Check 2: No orphaned migrated_id references (all point to existing source rows) - Check 3: Existing quote_items.service_id FKs remain valid (untouched) - Check 4: Existing offer_micro_services.service_id FKs remain valid (untouched) - Check 5: Report any unresolved name collisions (post-migration integrity) - Exits 0 only if all checks PASS Plus: push-services-migration.ts helper for direct SQL execution when drizzle-kit unavailable.
