The protocol doesn't consider that, and even if you could get such a clone to happen, it would be considered corrupt and a lot of things would be broken. Partial clone can be used to do something similar, but not completely the same. In such a case, you download stub objects that are filled in by a connection to the server on demand. What is most likely to have happened is that someone took a script that extracts the commits that touch a particular directory and created a new, entirely different repository and synthesized commits there with the same commit metadata. The two repositories are likely completely independent in terms of histories. Sorry there isn't a magic cool explanation for what's going on here, but it really is essentially a copy-and-paste into a different repo. -- brian m. carlson (he/him or they/them) Houston, Texas, US
