jschoubben 7641bb2059 A one-node mesh, and twelve things that have to be true of it
The common case, and the one that was never tested as a whole. What existed
asked whether four machines converged; it never asked whether ONE machine ends
up holding a mesh.

The order was wrong too. Three machines were enrolled second, into a mesh that
could not yet produce a single module, and that was reported as though something
had been shown. 17-raising-a-mesh is explicit: genesis ends with a mesh that
RUNS, and what remains after the core modules are built is "adding machines".
So the core comes first and machines arrive last — here, not at all, because a
second node is only meaningful once the first is complete.

Three things were missing entirely and nothing complained, because nothing asked:
the mesh never built its own catalogue, never had a store of its own for that
catalogue to use, and never rebuilt its own control plane through the module
path.

And four checks that were absent rather than failing:

  - it can describe itself — status, module list, plan --json, and the
    catalogue's five tools ASKED rather than observed. A container being up was
    being read as the catalogue working, which is the same error as matching a
    container by substring and finding the wrong one.
  - its networking is what the modules asked for — default closed, ssh open,
    declared ports open, .internal names written, module networks present. Left
    out altogether, which is hard to defend given the firewall work this week.
  - a change to a module's source reaches the machine on its own. The capability
    the migration depends on.
  - it comes back after a reboot. Never once tested; the lab had no way to
    restart a machine, because nothing had ever needed one.

Machines are named by role now — anchor, home-server, workstation, laptop — not
after the operator's own nodes, which made test output and real state hard to
tell apart.
