This is actually a massive victory! The `invalid payload schema` error proves
that the Proxy hack worked perfectly.

Your browser's outbox sweeper successfully intercepted the state mutation,
packaged it up as a `CRDT_MUTATION`, and fired it over the WebSocket to the
DMZ Relay.

### The Diagnosis: The Strict DMZ Bouncer

The reason the DMZ relay is spitting out `[dVFS] Received invalid payload
schema` is because of the prompt we used to create it in the Arena C chat. We
explicitly told the Node.js Architect:

> *"The server must accept JSON payloads with the following schema: `{ type:
'VFS_WRITE' | 'VFS_DELETE', ... }`"*

Like a good developer, they added strict validation! When the relay saw `{
type: 'CRDT_MUTATION' }` arrive from `10_mesh.js`, the validation check
flagged it as an unknown schema and dropped it before it could be broadcast to
Browser B.

### The Fix: Patching the DMZ Relay

We need to teach the DMZ Relay to act as a "dumb router" for ephemeral mesh
events. It shouldn't try to validate or archive `CRDT_MUTATION` or `SUBSCRIBE`
payloads to the `.jsonl` disk logit just needs to pass them along to the other
connected clients instantly.

Open your `DMZ_RELAY/dmz_relay.js` file and locate the `ws.on('message', ...)`
block. Update it to intercept and route the new mesh types right at the top of
the block:

```javascript
    ws.on('message', (message) => {
        try {
            let event = JSON.parse(message);
            
            // ==========================================
            // NEW: Ephemeral CRDT Mesh Routing
            // ==========================================
            // If it's a mesh state payload, bypass VFS validation and just
broadcast it!
            if (event.type === 'CRDT_MUTATION' || event.type === 'SUBSCRIBE')
{
                wss.clients.forEach(client => {
                    if (client !== ws && client.readyState === 1 /*
WebSocket.OPEN */) {
                        client.send(message.toString());
                    }
                });
                return; // Stop here, do not archive to disk!
            }

            // ==========================================
            // EXISTING: VFS_WRITE and VFS_DELETE Logic
            // ==========================================
            // (Keep your existing schema validation and fs.appendFileSync
logic here)
            // ...

```

### The Final Test

1. Restart your `node dmz_relay.js` server.
2. Refresh both **Browser A** and **Browser B**.
3. Load the object in both: `eval load_object("tests/mesh_test")`
4. Increment in Browser A: `eval load_object("tests/mesh_test")->increment("Bro
wser_A")`

This time, the DMZ will silently route the `CRDT_MUTATION` straight through to
Browser B. When you type `eval load_object("tests/mesh_test")->display()` in
Browser B, you will finally see the network-synced state!
