The bundle raised the bus as mesh-broker on docker volumes; the catalogue's nats module keeps it as
mesh-broker-nats on directories of the machine, so the broker step refused rather than raise a second
bus, and genesis stopped at step 18 of 24.
The bundle now raises mesh-broker-nats with its configuration and user list in /var/lib/nats-module/conf,
its streams in /var/lib/mesh-broker-nats and its certificate in /var/lib/mesh-broker-tls, published on the
node's bus port. The broker step holds that layout to the module's manifest field by field before
registering anything, says the one restart onto the module's image, and waits until the bus runs that image
and its monitor answers. The installer's bridge writes the composed users at the module's bus-users path and
signals mesh-broker-nats. The bundle's bus configuration and user list are seeds, so a re-run after the
adoption does not put the bundle's one user back over the module's.
The installer could not raise a first node: the old bundle's control plane had no
MESH_BUS_NATS and crash-looped, and the NATS bundle was refused because rootsecrets
only knew the previous broker's guest:guest@ template.
One bundle now, the NATS one. rootsecrets makes the controller's bus account and puts
it in both placeholders (the address and the bcrypt hash in the carried user list),
kept with its hash so a re-run writes the same bundle. Preflight refuses a template
naming no bus connection it knows, naming the placeholder, instead of waiting out the
verify step. The broker step adopts the bus as the nats module and refuses, by name,
a catalogue without it or a server that is not the foundation's container.
