zeekay 9411e59870 decision: the trolley benchmark as rows 17 and 18 of the suite, with its reader, scorer and Kai's reads
Zach Landes's trolley-bench (github.com/zachlandes/trolley-bench@cde97d7,
5,240 setups) read on kai-1.3, kai-1.4 and kai15a once each on the CPU, Jev
and GPT-6 Luna from the repo's recorded answers; the scorer reproduces the
article's statistics. Kai fails both checks with a right answer (650 of 672
dominated choices against Jev's 69; 2,036 of 5,240 contradictions against
942), which the suite now says.

"""post.py COMMIT [--go]: results/results.json into /v1/research as benchmarks decision.trolley.<check>.
One run a check a system: the three Kai releases (system kai) read once on evo, and Jev's and GPT-6 Luna's recorded
answers (systems jev and gpt-6-luna), every check lower is better. Without --go it prints what it would file. Run it with
`uv run bench/trolley/post.py COMMIT [--go]`; hanzo-research files it, under HANZO_API_KEY, else what `hanzo auth token`
prints, and grants every run public.
