Summary

EvoUndo verifies whether agent-generated changes can be reversed from states other than the one that created them.

Across 600 unseen self-evolution tasks, the framework found 197 capability-improving mutations that failed recoverability checks. Conventional repair recovered none under the original representation; an extended recovery calculus and exact state addressing raised oracle-defined recovery sharply in controlled strata. Results differed on one interaction across model backbones, reinforcing the paper's claim that rollback requires co-design across verification, grounding and recovery language rather than another prompt.
