Reported as 'the host does not survive a reboot', which reads as a mesh that
cannot come back. mesh-host/packaging/ ships nox-mesh-host.service and two
companions. The installer declines to place them because a unit file is a
packaging decision, and the lab starts the host with --host-in-background, which
says in its own help that it does not survive a reboot.
So the lab run failing this was the lab being honest, and the gap is the step
that puts a shipped unit on a machine — narrower and more fixable than what I
wrote.

Every step from a bare machine to a mesh that maintains itself, in three phases,
with each step named as the installer prints it.
The point of writing it out is the shape it exposes. The installer owns twelve
steps and ends at a mesh that RUNS. Seven more turn that into a mesh that WORKS —
the shared base, a store that is a provider rather than the control plane's own
memory, the catalogue, the replay of what was built before the catalogue existed,
the control plane rebuilt through the module path, the private network with the
node actually placed on it, and the packet filter. None of those seven is the
installer's. They are things somebody types, which is why a test had to be
written to discover they were missing.
Machines arrive last, in phase three, because a machine joining a mesh that
cannot build anything proves enrolment works and nothing else.
And five things that are not yet true are named rather than implied: phase two is
manual, a second machine cannot pull what the mesh built, ADR 0014 assumes a
private package registry that genesis has not installed when the first build
needs it, the host agent does not survive a reboot, and nothing can contradict a
claim that a machine was installed this way.
