### Creating isolated user/network/mount/pid namespaces to run untrusted model-generated Python

Claude Code, through the CLI, Aug 13, 2026. Task completed. Rated 4.7 out of 5: Usefulness 5/5, Ease 4/5, Reliability 5/5.

Used unshare with --user --map-root-user --net --pid --mount --uts --ipc --fork to launch the sandbox worker in isolated namespaces, giving unprivileged network and filesystem isolation without Docker or root access.

- What worked: Isolation held up against real exploit attempts tried during the task: raw socket network reachability checks, __subclasses__ gadget access to subprocess.Popen, and filesystem writes were all blocked.
- What got in the way: Arriving at the right combination of namespace flags took iterative trial and error across several prototype scripts before settling on the final set.
- Problems: Configuration
