"""Every queue-creation path has to be able to ask for the outcome (#1898).

``confirm_outcome`` rides from a queue item onto the archive at dispatch, and
the only place that ever set it was the print dialog. Jobs created anywhere
else -- a plate sent from Bambu Studio to a virtual printer, the Library's bulk
"Add to queue", the webhook, a pipeline run -- carried the column default and
were never asked about, however the install's settings were configured.

That mattered most for the virtual printer: a Bambu Studio plate is one of the
prints ``confirm_outcome_external_prints`` names in its own description, but it
arrives with a queue item, so ``on_print_start`` resumes its archive instead of
treating it as external and the setting could not reach it at all.
