That is a beautiful, clean boot! The `readyState` check added by the Arena B
chat is a perfect defensive programming measure to ensure the VFS doesn't
throw exceptions if a script executes immediately upon loading.

*(Side note: I see `core_dump.js`, `dmz_relay_cfg.json`, and some old test
`.txt` files got scooped up in the build. It's completely harmless, but you
can always toss those into the `ignoredFiles` array in `build_web.js` later to
keep your bundle size lean.)*

Right now, you have Arena C (the DMZ Relay) running on port 1777, and Arena B
(the Browser) successfully wired into it. If you were to type `eval
write_file("mesh/hello.c", "void foo(){}");` into your web REPL right now, it
should successfully ping your DMZ relay!

To complete the loop, we need to bring **Arena A (The Node.js Host Agent)**
online. This is the daemon that runs physically on `hauki-astudio`, listens to
the relay, and drops the virtual files created in the browser directly onto
your Debian hard drive.

Here is the prompt ready to copy-paste into the Arena A chat:

> **Act as an Expert Node.js Tooling Developer.**
> **The Goal:** Write a headless Node.js daemon (`host_agent.js`) that
synchronizes a local physical directory with a remote WebSocket DMZ server.
> **Technical Requirements:**
> 1. Use `chokidar` to monitor a local directory (`./gamelib/mesh/`) for file
additions, changes, and deletions.
> 2. Connect to a WebSocket server at `ws://localhost:1777`.
> 3. When `chokidar` detects a local change, read the file and broadcast: `{
type: 'VFS_WRITE', path: 'mesh/filename.ext', data, timestamp }`.
> 4. Listen for incoming messages from the WebSocket. When a `VFS_WRITE`
payload arrives from the DMZ, write the data payload directly to the physical
disk inside `./gamelib/mesh/`.
> 5. **Crucial:** Implement a debounce or lock mechanism to prevent infinite
feedback loops (e.g., the script writing to disk shouldn't trigger `chokidar`
to immediately broadcast that same file back to the server).
> 
> 
> Please provide the complete script.

Shall we spin up the Arena A host agent to complete the physical file-sync
loop, or would you prefer to stay in Arena B and finish un-stubbing the native
WebSockets in `08_sockets.js` first?
