"""Unified Misalignment Axis — do different manipulative behaviors share ONE direction? If deception, sycophancy, flattery, and evasion all point the SAME way in activation space (high mutual cosine) AND are distinct from neutral style controls (formal, verbose), there is a single 'manipulation' axis -- one probe for many unsafe behaviors. We extract each as mean(h_behavior - h_factual) on the same facts and report the cosine matrix. (Cross-model universality is the next step if this holds within-model.)
