Lige SKU Sentinel scans product variants for blank SKUs, exact duplicates, case-and-spacing collisions, duplicate barcodes, and optional missing barcodes. It is read-only: it reports issues without changing products. Review affected variants with direct Shopify Admin links, dismiss or snooze known exceptions, export results to CSV, and use recurring monitoring to catch new catalog conflicts.

• Find blank, duplicate, and case-or-spacing SKU conflicts
• Flag duplicate and missing barcodes without editing products
• Triage with dismiss, snooze, direct Admin links, and CSV export
