embabel ps

What this appliance has on the host, in the three groups that fail differently: its own containers, the deferred extras (allowed to be missing for the first quarter of an hour, and not a fault), and code sandboxes.

Sandboxes are the reason this verb exists. They are created by the server through the docker socket as siblings of the appliance rather than as compose services, so down does not take them and docker compose ps cannot see them. Until now they were visible only as one line inside doctor.
