 So adoption is not only an upgrade path. It is two rows of a mesh's module list becoming one,
 twice.
 
+## And it is one SERVER each, not two
+
+**The broker duplication is running today, not just latent.** The lavinmq module raises its own
+`server` container and points its provisioner at `http://lavinmq:15672` — a second LavinMQ,
+separate from the substrate's `mesh-broker`. A mesh with the module assigned runs both.
+
+This is not how LavinMQ is meant to be used, and the module's own provisioner says so: a consumer
+is given a *vhost* named for its login, isolated from every other consumer's by the vhost boundary
+— *"the exact analog of postgres's database-per-login"*. One server hosts the mesh's own control
+traffic on the `/` vhost and every consumer's broker as a vhost beside it. Two servers is the same
+mistake as two postgres containers, wearing AMQP.
+
+So adoption means the lavinmq module does not run a `server` of its own. Its server IS the
+substrate broker, adopted; the module contributes the provisioner, the tools, the event consumer
+and the run-once bootstrap that configures it — all against the one broker. Same for postgres: one
+server, the control plane's records in their databases and every module's database beside them.
+
+**The provisioner already assumes this** — it creates a vhost, not a broker — so the change is
+removing the second server, not building a new isolation model. What has to be designed is only the
+adoption itself: raising the one broker at genesis because nothing else can, then holding it as the
+module, over the broker it is.

 ## What makes this harder than it looks
 
 **The recursion is real, not incidental.** The control plane learns what modules exist by reading
