Excellent! The relay node perfectly picked up the configuration from your
parent directory (`../dmz_relay_cfg.json`), bypassed the port 8080 conflict,
and successfully bound to port 1777. The append-only journal is initialized
and ready.
To verify that the dVFS is correctly tracking state and appending to the log,
your next step is to test it with a client connection.
If you have `wscat` installed globally (`npm install -g wscat`), you can
connect a couple of terminal windows to see the mesh in action:
**1. Connect Client A:**
```bash
wscat -c ws://127.0.0.1:1777
```
**2. Send a Write Event (from Client A):**
Paste this JSON payload into the `wscat` prompt and hit Enter:
```json
{"type": "VFS_WRITE", "path": "/mud/areas/town_square.json", "data":
"{\"mobs\":[\"guard_1\"]}", "timestamp": 1725535000000}
```
*You should see the relay node's console log the processed event.*
**3. Connect Client B:**
Open a third terminal and connect another client:
```bash
wscat -c ws://127.0.0.1:1777
```
*Because of our "sync on connect" logic, Client B will immediately receive the
`town_square.json` payload you just pushed from Client A, and the
`mesh_archive.jsonl` file will now contain that event permanently.*
Let me know when you are ready to move on to the next phase of the MUD engine
architecture, or if you need to build the client-side dVFS adapter next!
