I know you use a query of some sort to fetch the assertion using the
artifact, but I can't recall if that's a Query or just a Request with
the artifact in it. I didn't implement it, so I'm not sure.

No, session-related timeouts are not part of the profile. Queries are
generally used to fetch additional assertions with attributes or request
authz decisions.
