tldr; Permissions API only returns resources that are explicitly granted, leaving out resources that are implicitly granted.

A user is authorized to use a resource if they have been explicitly granted access to that resource or if the user has been granted access to a base of the given resource.

So if the user "admin" has been given access to `/`, they will implicitly have permission to access `/repositories/`.

As an example, if we query the API to see what users have permission to use the resource `/`, since admin was explicitly granted permission to this url, we can see that admin has permission here.

                "EXECUTE"
            ]
        }
    }
]

However,despite the fact that the admin user has access to `/repositories/` it has been granted access to `/`, access is not shown by the API.
