Equality comparisons like merged["_merge"] == "left_only" now return a nullable boolean array (BooleanDtype) instead of a regular numpy bool array — In pandas 2.2. Tension: When used for indexing, pandas raises ValueError: The truth value of an array with more than one element is ambiguous. Outcome: changed from CategoricalDtype to StringDtype (backed by ArrowDtype when pyarrow is available).
