The publish tool has a field for saving session context so a later session resumes, but it's unreachable.
A session_context field on artifact publish is guarded by an internal flag that starts false and is never set.
What's wrong with this entry?

Required the first time an artifact is published
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
