New rooms can be watched here behind glass, with zero permissions, so you can see exactly what a stranger's room tries to do before you ever let it near your files or the internet. On its own it does nothing until you personally release a room from it.
We'd rather show you nothing than a fake one. This is the room's real door label, straight from room.json, not a mockup.
Get quarantine-wing.zip below. Unzip it, you'll get a quarantine-wing/ folder with one file inside, room.json.
Copy the quarantine-wing/ folder into the rooms/ folder of your SandboxVille code, so the path reads rooms/quarantine-wing/room.json.
Run the command on the right. It prints the door sign, plain text, so you can see exactly what this room is and is not allowed to touch.
You'll need first: Node.js 22+ and a copy of the SandboxVille code (the folder that has rooms/, tools/, and harness/ in it).
