-- Sub 2 — Post-migration verification. Run on local dev DB after upgrade.
-- Every SELECT should return 0 rows (anomalies). If any return > 0, migration has gaps.

-- 1. No part should have an empty part_number
SELECT id, name FROM fp_part_catalog
WHERE (part_number IS NULL OR part_number = '') AND active = TRUE;

-- 2. No part should have an empty revision
SELECT id, name, part_number FROM fp_part_catalog
WHERE (revision IS NULL OR revision = '') AND active = TRUE;

-- 3. Every description-template row with text in `description` should have
--    both internal_description and customer_facing_description populated
SELECT id, name FROM fp_sale_description_template
WHERE description IS NOT NULL
  AND description <> ''
  AND (
      internal_description IS NULL OR internal_description = ''
      OR customer_facing_description IS NULL OR customer_facing_description = ''
  );

-- 4. Every SO line with a non-empty `name` should have x_fc_internal_description set
SELECT id, order_id FROM sale_order_line
WHERE (name IS NOT NULL AND name <> '')
  AND (x_fc_internal_description IS NULL OR x_fc_internal_description = '');

-- 5. Every part should have certificate_requirement set (default 'inherit')
SELECT id, name FROM fp_part_catalog
WHERE certificate_requirement IS NULL;

-- 6. Count summary (informational)
SELECT 'parts_total' AS metric, COUNT(*) AS value FROM fp_part_catalog
UNION ALL
SELECT 'parts_inherit_cert', COUNT(*) FROM fp_part_catalog WHERE certificate_requirement = 'inherit'
UNION ALL
SELECT 'description_templates_total', COUNT(*) FROM fp_sale_description_template
UNION ALL
SELECT 'description_templates_with_both', COUNT(*) FROM fp_sale_description_template
    WHERE internal_description IS NOT NULL AND customer_facing_description IS NOT NULL
UNION ALL
SELECT 'so_lines_with_internal_desc', COUNT(*) FROM sale_order_line
    WHERE x_fc_internal_description IS NOT NULL AND x_fc_internal_description <> '';
