I'm leaning towards 'Yes', but I can't recall if it specifically mentions historical tasks in the documentation.

I feel like there might be another command for viewing historical tasks, but 'docker service ps' sounds familiar.

I think 'docker service ps http' should show the tasks, but I'm not entirely sure if it includes historical ones.

Wait, I'm a bit confused. Could it also be that the script debugging session is not active? I'll need to verify that as well.

Okay, let's see... I know Expedition is a migration tool, so I'll focus on the migration-related options.

I've got this! An authoritative record needs to have authenticity, integrity, reliability, and usability. That's option A, no doubt about it. I'm feeling good about this one.
