I have overview and topology information showing this is a beer rating platform with 14.3M ratings, 1.2M beers, 237K users, brewers, places, and geographic data. I also know the relationships are broken (zero viable joins), which is a critical constraint. To propose truly interesting questions, I should understand what gold tables exist - these pre-aggregated tables would reveal what analyses are already optimized for and what dimensions are most important. This will help me identify questions that are both analytically rich AND actually answerable given the dataset's structure.",
