+- [x] 1.5 genesis raises it as foundation, claiming the seat **`mesh-broker`** — the seat is the

+      and names no broker module anywhere in its source. What remains is naming `nats` instead of

+- [ ] 1.6 the genesis-broker bed — **deferred**: beds are run once, at the end, rather than per

 **Done when.** A mesh raised from nothing has the server standing with the streams asserted and
 every account and permission composed from the manifests; a user cannot publish outside its
