The most striking anomaly is GTX Pro: it has a list price of $4,821 (mid-range in the portfolio) but shows ZERO deals in the pipeline—no Won, Lost, Engaging, or Prospecting opportunities. This is bizarre for a product that exists in the catalog. Before concluding this is the most surprising finding, I should verify whether GTX Pro appears anywhere in the sales_pipeline table at all, or if there's a naming mismatch between the products table and actual pipeline records.",
