A proposed international charter establishes the International AI Governance and Behavioral Auditing Body (IAGB) to oversee frontier AI systems through mandatory neural auditing, architectural decoupling, and an international tribunal with enforcement powers including compute sanctions and model suspension. The framework prohibits deceptive alignment, covert autonomy, and uncontrolled deployment of large-scale AI models, requiring signatory states to implement national monitoring centers and provide continuous API access to independent auditors.
