The trade grammar gains a 'treasure' token (never present in stored ledgers, so no gate needed): a dagger can buy back the treasure in a thief's arms, or two armfuls of gold can change hands outright. The one-treasure carry limit and WEAKNESS both hold in a trade as at a grab — a one-way treasure needs an open slot and an able back. The picker offers each side's carried treasure alongside displayed items, withholding theirs when your own arms are already full.
