"What do we do with this information?"

Tell the lab to stop gain of function research.

Any kind of gain of function research lab needs to run under continuous international supervision from now on.

International Space Station (ISS) could serve as a good analogy here: have scientists and auditors from many countries in there so that we know what goes on day-to-day.

After that? Hold any country doing independent gain of function research responsible (from potentially building a bioweapon)
