One way I prevent possible catastrophic fuckups is that the 'doing code work' box that runs opencode or pi or whatever, is its entirely own separate VM and desktop environment (running as a xen or kvm guest and with its own LVM logical volume as boot/root and /home disk), than the machine running llama-server itself.

The harness gets the openai-compatible endpoint fed into it to talk to llama-server across the network, but the VM has no access whatsoever to my personal files, mail, backups/deep storage, fileserver, Documents folder, etc.
