            `outcome_side` describes directional exposure only; it does not change the order''s price. An order at price `p` with `outcome_side=no` is matched by an order at the same price `p` with `outcome_side=yes` — both parties trade at the same price, just on opposite directions.


            `outcome_side` and `book_side` will become the canonical way to determine order direction. The legacy `action`, `side`, and `is_yes` fields will be deprecated in a future release — please migrate to these new fields.
