コントラクト

• Exploding multiple list-like columns simultaneously with DataFrame.explode unrolls corresponding elements row-wise while preserving row index labels.
• Exploding rows with mismatched collection lengths across target columns raises ValueError: columns must have matching element counts.
• Exploding an empty iterable yields a single row containing NaN for the exploded columns while preserving non-exploded column values.
• Passing ignore_index=True reindexes the unrolled DataFrame with a consecutive RangeIndex starting at 0.
