  "description": "Arc 2b stop-geometry test on XAUUSD: the Arc 1 matrix under two wider vol-stop regimes (EMA-60 k=2 hourly-scale, EMA-240 k=3 multi-hour-scale) instead of Arc 1 minute-scale vol{3,k2}. Same constant round-trip cost (0.25 price units, stress parameter) + vol slippage. Question: does the cost drag collapse and leave a net-positive signal once the stop matches the H1 signal timescale?",
