This is great. I have some small suggestions that I think will be useful. I think we have the tests covered that need to be here.

I'm approving so you don't need to wait on me.

In meeting. Pain points are familiarity with the unit testing and specifically the subtlety mentioned above regarding the array index to check, and the error testing for an expected error message. Need some wiki pages or dev guide instructions on this.

@olyson said he sees the value, he was able to figure out how to get it to work on his own, and would do again.

Cool, this is great @olyson. I'll look at that last conversation, and see if there's anything I come up with. But, this completes your part of this, and then I'll do my parts and send it to b4b-dev. Thanks so much!

Testing for aux_clm on Derecho and Izumi is done and looks good.
