    "reasoning": "I have match counts by year showing the temporal evolution of World Cup tournaments. I can see clear structural breaks: tournaments grew from 18 matches (1930) to 64 matches (1998-2022), with notable jumps at 1958 (+3 matches), 1974 (+6), 1982 (+14), and 1998 (+12). To provide a complete temporal analysis, I should also examine the other temporal dimensions in the dataset: attendance patterns over time, FIFA ranking changes between the two snapshots, and the 2026 schedule. Let me query attendance trends from the world_cup table to see if there are notable spikes or dips in tournament attendance.",
