 "about": "Zach Landes's trolley benchmark (Jev Meets the Trolley Problem, 2026-10-14; zachlandes/trolley-bench at cde97d7, 5,240 setups in eleven families, 24 wordings a family, both description orders), scored by hanzo-inc/kai bench/trolley/score.py, which reproduces the article's own numbers from the repository's recorded answers before any Kai answer is scored. Kai is kai-1.8 deciding through its Nio policy (nio/harm@1) over the counts it grounds from each setup at floor .9, every setup once on evo's x86-64 CPU, 2026-10-20 (hanzo-inc/kai results/ground/run12r/trolley.score.json). Jev and GPT-6 Luna are the repository's recorded answers, never called. Every check lower is better. The sealed read is ground-8, two registers no run was trained on or read on before (quarry, piste), hashed before the model was frozen and read once at floor .9 (results/ground/run12r/README.md).",
