I'm curious to investigate, did it get relayed in a way that corrupted it?

Your instinct is absolutely dead-on. It didn't just get corruptedit got
**Base64 encoded!**

If you look back at the `wscat.log` from your previous test, look at exactly
what the Host Agent pushed to the DMZ Relay:
`"data":"Ly8gZ2FtZWxpYi9tZXNoL2dlbmVzaXNfZ3JpZC5jCm9...`

That string of gibberish is standard Base64. `Ly8g` is Base64 for `// `.

When your Node.js Host Agent reads a file from the hard drive, it's reading
the raw binary `Buffer`. Because it's transmitting that buffer over JSON, it
automatically serializes the binary into a Base64 string to keep it safe.

### The Reload Overwrite Trap

This explains exactly why you got the `Unexpected end of input` crash on
reload:

1. When you run `node build_web.js`, it packages the perfect, plain-text LPC
code into `index.html`.
2. When you reload Browser A, it connects to the DMZ Relay.
3. The DMZ Relay has a feature where it plays back its `mesh_archive.jsonl`
history to new clients to get them up to speed.
4. The DMZ immediately blasts Browser A with the Base64 version of
`genesis_grid.c`, **overwriting the good plain-text version in your VFS!**
5. When you type `eval load_object(...)`, the JIT compiler tries to lex the
string `Ly8gZ2FtZW...`. Because it's just one giant block of letters with no
LPC syntax, it hits the end of the file expecting a function block and
crashes!

### The Fix: The Browser Base64 Unwrapper

Rather than rewriting the Host Agent, we can just make the browser's Virtual
Filesystem smart enough to detect Base64 payloads and automatically decode
them back into plain text.

Open your `template.html` file and update your `dmzSocket.onmessage` listener
(the VFS one, around line 160) to look exactly like this:

```javascript
        dmzSocket.onmessage = async (event) => {
            try {
                // Robustly unwrap Blob binary frames sent by Node.js
                const payloadStr = event.data instanceof Blob ? await
event.data.text() : event.data;
                const msg = JSON.parse(payloadStr);
                const terminalOutput = document.getElementById('output');
                
                if (msg.type === 'VFS_WRITE' && msg.path) {
                    let fileData = msg.data;
                    
                    // NEW: Base64 Auto-Decoder for Host Agent payloads
                    // If the payload has no spaces, is divisible by 4, and
uses valid charset, decode it!
                    if (typeof fileData === 'string' && !fileData.includes('
') && fileData.length % 4 === 0 && /^[A-Za-z0-9+/]+={0,2}$/.test(fileData)) {
                        try { fileData = atob(fileData); } catch (e) {}
                    }
                    
                    window.__VFS[msg.path] = fileData;
                    terminalOutput.textContent += `
[DMZ] Incoming sync applied: ${msg.path}
`;
                    terminalOutput.scrollTop = terminalOutput.scrollHeight;
                } else if (msg.type === 'VFS_DELETE' && msg.path) {
                    delete window.__VFS[msg.path];
                    terminalOutput.textContent += `
[DMZ] Remote deletion applied: ${msg.path}
`;
                    terminalOutput.scrollTop = terminalOutput.scrollHeight;
                }
            } catch (e) {
                console.error("DMZ Sync Error:", e);
            }
        };

```

Run `node build_web.js` one last time.

Now, when you reload the browser and the DMZ Relay blasts it with the archived
Base64 file, the browser will seamlessly intercept it, decode it via `atob()`,
and save the pristine LPC code to `window.__VFS`. You'll be able to boot the
Genesis Grid and test your new `display()` function immediately!
