    "reasoning": "I've reviewed the evidence and found several interesting patterns, but I want to explore one particularly striking anomaly: GTX Pro appears in the products table with a sales price of $4,821, yet has ZERO deals in the sales pipeline (step-8), while GTXPro (no space) has 1,480 deals and $3.5M in won value (step-9). This suggests either a data quality issue (typo/naming inconsistency) or two genuinely different products where one is listed but never sold. I need to verify this is indeed two separate products by checking the products table directly and searching for any GTX Pro deals.",
