How to Play
1. Inspect
Review issue markers, distributions, ranges, categories, and duplicates. Rare values are not always errors.
2. Clean
Apply focused tools. Preserve useful rows. Every action consumes time, actions, or budget.
3. Validate
Submit when quality is high. Your score balances correctness, retention, consistency, efficiency, speed, and reproducibility.
