Merge the runner sandbox: g1t-runner sandbox up makes a person's own computer a self-hosted runner that nothing a job runs can get out of. Linux jobs run in a Linux VM of the runner's own (a WSL 2 distribution with no host mounts, interop or Docker socket on Windows; vfkit on macOS; Sysbox, or QEMU and KVM, on Linux), each in a fresh container under Sysbox inside it; on Windows 11 Pro and up, Windows jobs each run in a Windows Sandbox discarded after the job. Runners report their isolation, and the Runners page shows it.1//! Jobs native to the runner's own OS, each in a throwaway virtual machine
2//! made for it and destroyed after: `vm` isolation (sandbox.rs).
3//!
4//! - **Windows: Windows Sandbox**, through its command line (`wsb`, in
5//! Windows 11 24H2 and later). Each job gets a fresh sandbox: a Hyper-V
6//! VM with its own kernel, started from the machine's own Windows image
7//! and discarded, disk and all, when it stops. Its configuration turns
8//! off everything that reaches the machine: no GPU, no clipboard, no
9//! printers, no microphone or camera, and one folder mapped read-only,
10//! which holds only a copy of the harness and the job's script. The
11//! runner on the machine starts the sandbox, runs the script in it as
12//! SYSTEM (`wsb exec`, which waits and returns the exit code) and stops
13//! it. Windows Sandbox needs Windows 11 Pro, Enterprise or Education
14//! with the Windows Sandbox feature on; it is not in Home.
15//!
16//! Chosen over Hyper-V-isolated Windows containers, which need the
17//! Containers and Hyper-V features (Windows 11 Pro or Enterprise, and an
18//! administrator to turn them on), a container engine in Windows
19//! containers mode, and an image matching the machine's Windows build.
20//! A Windows Sandbox needs none of that, only the one feature, and its
21//! disposable VM is the same kind of wall.
22//!
23//! - **macOS: a cloned macOS VM** (designed, not run on a Mac yet). Each
24//! job gets an APFS clone of a signed macOS image, booted with Apple's
25//! Virtualization framework through `tart` with no display, no audio,
26//! no clipboard and no shared folder, and deleted after. Apple's licence
27//! allows two macOS VMs per Mac at once ([`MacVm::MAX_VMS`]); a runner
28//! runs one job at a time, so a Mac runs at most two such runners.

Merge the runner sandbox: g1t-runner sandbox up makes a person's own computer a self-hosted runner that nothing a job runs can get out of. Linux jobs run in a Linux VM of the runner's own (a WSL 2 distribution with no host mounts, interop or Docker socket on Windows; vfkit on macOS; Sysbox, or QEMU and KVM, on Linux), each in a fresh container under Sysbox inside it; on Windows 11 Pro and up, Windows jobs each run in a Windows Sandbox discarded after the job. Runners report their isolation, and the Runners page shows it.423 fn wsb_output_reads() {
