I'm not finding anything about this scenario in the wikis.
What do you mean? The responses have detailed a variety of situations, it boils down to the fact that you need to present an approved negative test prior to boarding a flight inbound the the USA. Of course people have presented alternatives but the crux of issue is you need to present a negative test.
I think the wiki covers this pretty well?
