## Summary

Weight space editing allows advanced frontier models to modify knowledge and behavior through direct weight modification\. This capability creates an opportunity for one model to induce unauthorized behavior in another, termed weight space misfolding\. Targeted disruption is possible, but limitations in reliability and functional preservation are significant\.
