    "reasoning": "I've found a major discrepancy: 'GTXPro' appears 1,480 times in sales_pipeline but is completely absent from the products table (which lists 'GTX Pro' instead). This naming mismatch means 1,480 deals worth $3.5M can't be linked to product metadata. Before concluding this is the most surprising finding, I should check if there are other similar data quality issues or unexpected patterns. Let me examine the relationship between product names across tables and check for other anomalies.",
