 the formal verification is just that the authors found a single
example that failed.  whether they used formal verification to find
it, well, they didn't actually publish the source code of their
techniques, so big deal.

 and, if they formally verified a flawed design because they didn't
study and implement it properly, that means the paper is useless on
two counts.
