    "reasoning": "I have daily call volume and AI resolution data, but to find the most surprising pattern I need to look deeper at the unnamed columns (_unnamed_7, _unnamed_8, _unnamed_9) which appear to contain additional metrics. The inspect_columns results show these have high distinct counts (117, 142, 5 respectively) and ranges that mention 'Duration', 'Sentiment Score', and 'Sentiment Label'. I should query a sample of rows to see what these columns actually contain, as they may reveal counterintuitive patterns about call handling that aren't visible in the aggregate metrics.",
