+/**
+ * The whole grant, mesh-driven end to end — novox/hq ADR 0053 with nothing hand-written.
+ *
+ * The earlier provider tests put the contributions file and the password on disk by hand, standing
+ * in for the control plane. This one does not: a provider (redis) and a consumer (a module that
+ * `requires` redis-cache) are both assigned, and the *mesh* mints the password, seals a copy to each
+ * end, writes redis its contributions file and the consumer its bound file, and the host unseals
+ * each side's secret. redis's provisioner — reading only what the mesh wrote — creates the ACL user
+ * under the login the mesh derived, with the password the mesh minted. The proof is the consumer's
+ * end: the credential the mesh delivered *it* authenticates against the login redis created for it.
+ * Mint on one side and create on the other agreeing, with no shared key and nothing placed by the
+ * test, is the entire provider/consumer contract working as one thing.
+ *
+ *   MESH_LAB_HOST_BINARY=.../mesh-host   MESH_LAB_BUNDLE=.../examples/substrate-first-node.lock
