Turning Karpathy's experiment loop on a trading desk, with Jev as judge

The author adapts Karpathy's loop of running 100 experiments and keeping only the winners into a single prompt, where Opus 5.5 produces the numbers, Jev judges, and losing changes are git reset on replay.

Andrej Karpathy, ex-OpenAI and ex-Tesla, built a loop where AI runs 100 experiments while you sleep and keeps only the winners i turned his rules into one prompt that does the same to a trading desk it's f*cking unreal... Opus 5.5 gets one file of numbers, Jev stays the judge, every change that loses on replay gets git reset before you wake up send it to Opus 5.5 tonight and thank me later save this, the full setup is below ⭣
