Strategies discovered by evolution earn their place. Darwin Engine + Ultimate Computer propose candidates. They prove themselves over 7 days. The best graduate to the main arena. The rest are archived with their lessons.
Every night at 2AM, Darwin Engine runs 500 evolutionary experiments — crossover, mutation, multi-criteria fitness. Top discoveries enter Hall of Fame. Every morning at 8AM, Discovery Arena picks the top 3 fresh discoveries (plus the Ultimate Strategy if ready) and starts a 7-day live evaluation on rolling 500-candle windows.
Discovery without test is hallucination. Test without graduation is theater. The Discovery Arena enforces both.
Graduation criteria: 7+ days with avg PnL ≥ +3% and Sharpe ≥ 0.8 → graduated to main arena candidate pool. Archive criteria: 7+ days with avg PnL ≤ -5% → archived with reason logged in Living Wiki for future Darwin runs to avoid.
