I added this because the original issue is related to an invalid file but makes me think this is a bug instead of a docs issue. @jeffkl what do you think?

Normally this would be a different scenario.

We'd have another Issue, Solution etc.

We should also call out that this is a special case, since in a properly onboarded CPM scenario, you'd get NU1008.

I wasn't sure if I should put it in another Solution section since it's the same error but yeah it's a special case so I can start with that

Here's prior art from both restore and pack.

When CPM is enabled, is the warning/error message the same, or different?

If the warning/error message is different when CPM is enabled compared to when it's not, it's important to have a sample of the message in these docs so that if the customer searches those words, they're more likely to find these docs.

nit: my readability preference would be for something between these two words..
