    "reasoning": "The data structure is confusing - I'm seeing both daily summaries and individual call records mixed together. I need to understand the actual structure better. The 'Day' column contains both day-of-week labels (Thu, Fri), dates (23-Jun, 01-Jul), summary labels (TOTAL, Today), section headers (=== DAILY TREND...), and call IDs (CY-2847). I need to filter to just the actual daily date records to properly analyze the volume vs performance relationship.",
