Did you do a "mv" somewhere in there?  Or just forget to paste it?

I'm still biased to think it's probably fine.  Although Jonathan had one
test which produced a bad result, the assumption was that it would have been
good.  And given that Adam had a good result, it's probably just something
weird and specific to something that Jonathan unfortunately has right now
...

Still, Tom, there's no harm in actually doing the test, if you'd care to
repeat it or paste it or whatever.  Cuz it's not shown below.
