Short summary

Language models confidently emit wrong financial numbers when they compute them. Databricks Cost Leak Hunter demonstrates the architectural fix: SQL joins are the single source of truth for every dollar figure, while the LLM only analyzes and explains. This pattern prevents the failure mode of clean, well-formatted, completely wrong reports.
