The accessor returned (result, span) tuple — sole exception among all indicators. Strategy loops expecting Series | DataFrame broke with AttributeError. Removed _mp_worker ichimoku special-case. Updated class docstring and indicators reference page to clarify function returns two DataFrames while accessor returns one. Added accessor return-type conformance test validating all 232 indicators return Series | DataFrame. BREAKING CHANGE: df.ta.ichimoku() no longer returns (DataFrame, DataFrame). Access callers needing forward Span must use pandas_ta.ichimoku() directly.
