| `hanzo pubsub publish` | Puts one message on the org's bus.                                                                                                                             |
| `hanzo pubsub request` | Sends one request on the org's bus and waits for one reply — the synchronous half of pub/sub, for callers speaking to a responder subscribed on the NATS port. |
