can TOR be considered to be on the transport layer though? i thought it worked with TCP, so it would need to be at least OSI level 5 iirc?

You're right; actually tor reside in the application layer I think (above TLS).

Although conceptually speaking it is itself a transport layer I guess.

OSI level is cute, especially once you start to interpret ip over https ;)

Tor is a layer 4 overlay network.

Layer 5 would be HTTP, layer 6 would be the content (JPEG, MP4, etc.), and layer 7 would be the application serving or sending the HTTP requests/content.
