S&P 500, long/short SMA 50/200

FAIL — published anyway

A track record judged by the MIZAN gate inside a zero-knowledge proof: returns after costs, the out-of-sample split and the overfitting corrections recomputed in-circuit, the strategy never revealed. Anyone can verify this credential offline. Every verdict on the registry is published, including this one.

Strategy-archetype sweep, one control asset: long/short SMA 50/200 (short-capable golden cross) on the S&P — refused. Sharpe 0 against the 1.20 bar. Twelve archetypes exercising every DSL feature — indicators, long/short, regime gates, vol targeting, ensembles, crash brakes, leverage — twelve refusals. The gate does not care how the strategy is shaped.
