Inventory reconciliation by SKU — demonstration

Synthetic-data demonstration of matching a product catalog to a stock file by SKU. The workflow matches A01 and A02, flags A03 as missing a stock record, and separately reports A04 as a stock record without a catalog match.

Zero stock is preserved as zero, while missing stock remains unknown. This avoids hiding discrepancies or inventing inventory quantities. Outputs include a reconciled table and exception list for review. An Arratz demonstration, not a client commission.
