OrderAlreadyProcessed

The object or state already exists; treat the goal as met or pick a different target

The order id already has a terminal status: execution found it fulfilled, or cancel_order found any existing status for it. Check the Orders storage map under the blake2-256 hash of the SCALE-encoded VersionedOrder.

Declared by the LimitOrders pallet; it classifies to the semantic code already_exists.
