Adding Hazmat under Command-line tools.
Hazmat is a macOS containment CLI for AI coding agents and risky local scripts. The work runs under its own UID (not the admin's), under a Seatbelt policy applied via
sandbox_init()from a small privileged helper (notsandbox-exec), with PF anchors and DNS blocklists for per-session network policy, plus backup/rollback for reversible host setup.The design is checked in TLA+ across nine specs (~44,795 states) covering setup/rollback ordering, seatbelt credential-deny policy, backup safety, version migration, Tier 2/Tier 3 policy equivalence, session-time host permission repairs, harness lifecycle, and helper fd hygiene before
sandbox_init.https://github.com/dredozubov/hazmat
