    "reasoning": "I have evidence showing this is a data intelligence telemetry platform with three operational layers. The batches table shows processing volume metrics (total_rows, total_bytes, elapsed_ms) and the LLM usage data shows AI costs and token consumption. To determine the most important metric, I should examine the actual volume and distribution of both processing activity and LLM usage. Let me query the batches to see total processing volume by status, which represents the core operational health of the platform.",
