I wonder if it's useful to set a bound in the AWK file, so that once it sees a particular state hash, it exits, to prevent swapping valid balances

Also, init comment in PR should say how it was tested (per discussion last week)

Looking again, doesn't the Claimed message indicate where there's a swap? If the values aren't swapped, that message doesn't appear. That can be used to trigger calling the swapper, or not.
