NVIDIA's OpenClaw sandbox plugin. Landlock + seccomp + netns + transparent inference proxy.
Orthogonal contribution: secrets physically cannot exist in the sandbox.
NemoClaw in one sentence: It wraps OpenClaw inside NVIDIA OpenShell (Landlock + seccomp + network namespaces), intercepts all model API calls before they leave the sandbox, and routes them to Nemotron — so the agent holds no credentials. The rest is operator-controlled egress policy.
