I have orientation from the overview (step-0) showing this is Titanic passenger data with survival outcomes, demographics, ticketing, and cabin info. I also have the gold tables list (step-1) showing pre-aggregated breakdowns by Sex, Pclass, Survived, Cabin, Parch, and combinations. To identify the most interesting questions, I should understand what dimensions and measures are available and what patterns might be analytically rich. Let me inspect the raw table's columns to see the full attribute set and data quality, which will help me propose questions grounded in what the data actually contains.",
