What's this about?
Nvidia introduced OpenShell to constrain an agent's permissions and Sentry to monitor behaviour on separate networking hardware. It says independent controls are needed because model-level instructions cannot reliably govern every action.
What exactly is an independent trust layer?
It is a guard outside the agent's own reasoning, like a building access card system that can block a door even if the person asking to enter sounds convincing.

- Many joked that a chip company naturally solved the problem by proposing another chip.
- Security-minded commenters asked what this adds beyond least-privilege accounts, sandboxes and policy gateways.
- Others welcomed hardware-separated monitoring but stressed that voluntary controls still fail when operators misconfigure them.
