It highlights that BlueField-4 only-path-to-the-model guarantees apply in Vera Rubin POD designs and are unspecified for heterogeneous environments with third-party APIs or non-NVIDIA hardware. OpenShell is open source while full isolation is hardware-gated, making full-stack safety a tiered product. The piece contrasts OpenAI's reported detection-without-auto-termination gap with NVIDIA's millisecond isolation claim, noting coverage depends on traffic actually traversing the DPU, and asks who audits the auditor when the auditor is also the vendor.","sledRelevance":"Useful Pass B framing for SLED security architecture and procurement: treat OpenShell and Sentry as tiered controls, demand path-coverage evidence outside NVIDIA POD designs, and keep independent oversight of vendor-operated enforcement layers.","evidence":"Opened SUPERCRZY article dated September 29, 2026.
