OK, snuck in the reversion of f/mx to pre-cleanup, and did a push -f on main in case anyone has been working the broken version. New SHA: 7e73c62f015845900807368349562319be0cdebf
f/mx-sampler now running off 7e73c62f015845900807368349562319be0cdebf
The Todo demo in f/mx (and f/mx-sampler) seems OK, @baptiste-from-paris
x07 is fixed, but have discovered Todo demo malfunctions. @baptiste-from-paris, I just checked f/mx SHA 6cda131 from before the big cleanup and it works fine. Short day tomorrow, back Friday.
