min_total_out of asset_out across all routes.routes: the split ā each Route.amount_in of asset_in through its
own path. sum(amount_in) must equal total_amount_in - fee. A
path of more than one Step is a chained multi-hop (AāCāB): each hop
after the first swaps exactly what the previous hop deposited into the
router (its Step.amount_in is advisory only), so the intermediate
amount never has to be predicted at signing time.The fee skim is retained in the contract in the input asset and
swept/converted to the fee asset later by the owner (deferred ā avoids a
second in-band swap in every user transaction). fee_to is read from
storage, never the caller.
