The trusted evolution framework: governing cognitive stability in self-evolving foundation models
摘要
As foundation models evolve from disembodied inference to embodied intelligence, their capacity for self-evolution introduces new risks to cognitive stability. This study examines how autonomous adaptation in embodied foundation models can undermine internal coherence and mission reliability. Using the OODA loop to structure the cognition-action cycle, we identify functional evolution boundaries that distinguish adaptive from unsafe learning. We formalize key cognitive degradation mechanisms, including representation drift, reward misalignment, and coupling amplification. We further analyze how such degradation propagates across perception, reasoning, and control. Building on this analysis, we propose the Trusted Evolution Framework (TEF), a governance architecture for bounded self-evolution. TEF introduces formal stability criteria and quantitative indicators to regulate adaptive dynamics and maintain cognitive coherence. Theoretical validation and application pathways demonstrate that TEF enables adaptive agents to evolve safely while preserving flexibility and trust. This work provides a theoretical foundation for cognitive robustness in self-evolving systems.
