Hi Volkan,

> We are unable to legalize the test below because of the missing combine.

This sentence jumped at me. Are you saying we have mandatory combines at this point for legalization to work?
Although that wouldn't surprise me, I would like we have a clear list of what they are (if that's not already the case.)

Cheers,
