Drawdown-first.
On high-volatility assets — crypto, volatile equities — Delta holds portfolio drawdown to 1.4–3.2% where buy-and-hold takes 16–34%. The pipeline is integer-deterministic: identical input gives a bit-identical regime fingerprint on x86-64 and ARM.
stated openly
Not a broad-market alpha engine.
Delta underperforms buy-and-hold on returns and Sharpe in every out-of-sample regime. It is built for drawdown protection on volatile assets — avoid mature large-cap defensives and anything under ~15% annualised volatility. The decomposition mechanics stay sealed.
