Why we stopped backtesting our intelligence layer (and what we found instead)

Backtests are the right tool for trading strategies. They're the wrong tool for AI reasoning infrastructure. We tested Chart Library against itself: two identical Claude agents, one with our tools, one without. A blind LLM judge scored their reasoning across 50 out-of-sample scenarios. The agent with Chart Library won 50-0. Every reasoning dimension lifted. Paired t-statistic above 10 on every dimension. Here's how we got here.
