Use at the start of any session running inside the sandbox VM. Signals you are inside the VM — env var SANDBOX_VM=1, file /etc/sandbox-vm-release, or hostname sandbox. Covers the disposable NixOS environment, nix profile installs, docker, host directories mounted at ~/mnt/<name>, and the $SANDBOX_VM_STATE convention for routing tool-managed state (venvs, node_modules, target/, .gradle/, test/lint caches) out of host-mounted projects.
