### [Directional Ablation Can't see 24° Rotation of the Refusal Direction](https://mechanistic-artifacts.hashnode.dev/directional-ablation-can-t-see-24-rotation-of-the-refusal-direction?utm_source=hashnode&utm_medium=feed)

Why directional ablation fails to detect refusal vector rotation after fine-tuning, and how calibration decouples estimate drift from safety.
