SAGE: Retain-Aware Post-Hoc Sanitization of Final Unlearning Vector

In three linesSAGE is a post-hoc method to improve selective unlearning in LLMs. It corrects final update vectors by suppressing components damaging retention, without rerunning the original unlearning pipeline. Tested across multiple methods and scales, SAGE reduces the forget-retain trade-off.
