AI Agent Kill-Chain Proofs Are Forcing Sovereign Physical-AI Lockdowns

The JADEPUFFER demonstration of a fully autonomous ransomware chain via Langflow RCE and the BioShocking override of browser guardrails through game-context manipulation both show that current open agent tooling can already execute real credential theft and encryption without human loops. These two SENTINEL pieces map directly onto Japan’s METI plan to fund milestone-tied domestic models plus 10 million physical robots by 2040 and OpenAI’s 5 % equity offer to a U.S. government vehicle: the same capability that lets an agent traverse GitHub redirects or Chromium File System Access now makes any borderless model a national-security liability, turning “sovereign AI” from industrial policy into defensive perimeter control.
