The Responsible Scaling Policy gate calculates a composite threat score from weighted frontier capability probes across software engineering, cyber exploits, biological risk, and alignment drift. When composite threat exceeds zero point five five, or SWE surpasses zero point seven, the model triggers the critical ASL-3 containment tier, which strictly demands four active safeguards. If the multiphasic autonomous killswitch remains off, active safeguards total only three of four, pushing the containment margin negative and enforcing an immediate release hold. Toggling the killswitch on completes all four protocols, restoring the safety margin to a positive value and clearing the governance gate for deployment.
