+/**
+ * The mesh assigns a SECOND wave of modules to one node in a single push — the ones converted this
+ * session — and they resolve and come up together. catalogue-small's sibling, a heavier group.
+ *
+ * The four exercise the three converted shapes (novox/hq ADR 0039/0048/0052):
+ *   - mongodb  — a database PROVIDER shaped like postgres: a server and a broker-bound runtime
+ *     (carrying `mongosh`) on the private mongodb network, the runtime running the provisioner over
+ *     the ADR-0048 MESH_RECEIVES contract. Its consumer proves the provisioner ran by connecting
+ *     with the mesh-minted credential.
+ *   - unifi    — a tooled APP shaped like plex: a server and a broker-bound runtime that serves the
+ *     module's tools under a scoped account. No provisioner. (Lab credentials are set on the runtime
+ *     so unifi's client constructs and its tools register — as plex is given a lab token.)
+ *   - marrytts — a manifest-only PLAIN container: no runtime, no tools, no broker account. The proof
+ *     is simply that its container comes up under the co-resident push.
+ *   - postgres — the known-good provider control, verbatim from catalogue-small, so a mongodb-only
+ *     provisioning failure is unmistakable against a provider that is already proven.
+ *
+ * All are assigned to the one anchor, pushed ONCE, and the node converges ONCE with every one up.
+ *
+ *   MESH_LAB_HOST_BINARY=.../mesh-host   MESH_LAB_BUNDLE=.../examples/substrate-first-node.lock
