• Artifact service is going to be global for a given instance, ultimately.
• Docker is orchestrated with client API instead of command line tool.

Ah dang it. This is not yet ready. Please disregard.

This should be OK to look at now.

I could make the artifact handling more robust (and not a memory leak), or even set up "prism runner w/container" runs as a pre commit, but I think I'd like those as separate PRs.

I don't love the current test coverage, but it seems tricky to do for the time being, and that gets covered by adding the full suite runs.
