*looks at the ticket and your approach*

Why not just run and query an Onionoo server? It seems silly to
duplicate this effort. You can still put that code in a separate daemon
if you want to minimise changes to the Facilitator itself, but it won't
have to handle any of the hard stuff. Just ping it a request like GET
http://onionoo.local/details?search= and parse the
returned JSON to check the exit policy.
