The runner user is not root, so the host chown failed and `|| true` hid it.
The app (uid 1000) then could not unpack the declared module into ./modules,
came up healthy with no module, and seed:demo refused the fixture's
rust.command.run event (website run 358, the first scheduled wipe).
A throwaway container runs as root and the runner is in the docker group, so
the chown now happens there, and a failure stops the run at that step.
