-- ✅ MIGRATION COMPLETE! ✅
-- Both indexes have non_unique = 1, which means:
-- - No unique constraint exists
-- - Multiple bids from same supplier for same inquiry are allowed

-- Final verification:
SHOW INDEX FROM `bids` WHERE Column_name IN ('inquiryId', 'supplierId');

-- Expected result:
-- ✅ supplierId: non_unique = 1 (foreign key index, allows duplicates)
-- ✅ idx_bids_inquiry_supplier: non_unique = 1 (composite index, allows duplicates)
-- ✅ NO index with non_unique = 0 (unique constraint removed)

-- The database is ready for multiple bids!
