Computer-use sandbox framework for Codex on headless Linux

I built a computer use sandbox framework for codex on headless linux. GPU passthrough, computer use, and sudo access for codex all work. It's the perfect dev sandbox to allow full auto work while minimizing the "rm -rf /" risk

superSmitty9999 released ai-sandbox-manager as a PoC that uses LXC templates to give Codex sudo access, browser use, Docker, and shared GPU access, with a hook that blocks git push while the agent works inside isolated copies.

Why it matters: HKR-H/K/R all pass, but this is a Reddit personal PoC with mechanisms only, not adoption, benchmarks or maturity evidence. It fits the featured floor for practical agent-sandbox work.
