Hello, I have a strange behaviour which might turn out not to be a bug but I have no way to tell. On my installation if I do:

$ ./bin/repository list-paths | grep -i gcc
| rGCC        | /var/repo/GCC/        |
$ ls /var/repo/GCC/
ls: cannot access '/var/repo/GCC/': No such file or directory

This is surprising because I expected all repositories to be valid. I can see this project in diffusion.
It's currently Importing (95.38%)... and in Policies it says:

Visible To
    All Users 
Editable By
    Administrators 
Pushable By
    Not a Hosted Repository

Note the Not a Hosted Repository. I wonder if this repository existed in the past (this is a phabricator installation from 2015), then I made it observe Phabricator deleted the repo from the filesystem but left something somewhere such that bin/repository list-path still lists it.
Can I post something else to help with understanding this bug? I am not sure myself what more I can offer for reproduction since it might just be an artifact of how old this phabricator instance is.
