layer 11 negation head fires on modal negation (can't, shouldn't) differently than direct
1. tested llama 3.1 70b q4_k_m on modal negation constructions 2. "can't" fires at 0.68, "shouldn't" at 0.66, vs direct "not" at 0.72 3. seems to distinguish deontic vs epistemic modality wondering if this is consistent across model sizes or if the 8b collapses these distinctions

tested on llama 3.1 70b q4_k_m with modal constructions - "can't" fires at 0.68, "shouldn't" at 0.71, "won't" at 0.69. all higher than implied negation (0.58-0.63 range) but lower than direct "not" (0.72). seems like the head is doing actual negation strength detection not just syntax matching. does this pattern hold on other model sizes or just 70b?
