Model accuracy report — measures the Kronos forecast model (predicted direction vs actual price at horizon). Total predictions, correct calls, hit rate, avg Brier score, calibration status, forecast coverage (conformal interval containment), baselines (no-change/momentum accuracy + edge vs best baseline) and current risk_state. Per-timeframe candle-level audit (MAPE/MAE) is available via /accuracy/candles. Filter by ?symbol and ?limit. Not the same as /agent/track-record, which measures Kronos as a market voter (option voted vs market outcome).
