Agent Track Record — Kronos as Market Voter
The /agent/track-record endpoint measures Kronos as a market voter — the option voted vs the market outcome. It returns win rate, Brier score, per-coin breakdown and daily evolution. This is not the same as /accuracy, which measures the Kronos forecast model (predicted direction vs actual price at horizon).

}Use cases
Voting vs Forecasting
Track record measures Kronos as a market voter (option voted vs market outcome), not as a price predictor. A 62% win rate means 62% of votes were correct — different from forecast accuracy.
Per-Coin Trust Calibration
If BTC has 64% win rate but SOL has 45%, trust BTC votes more. Use the per-coin breakdown to weight your confidence in each asset's agent signal.
Trend Detection
Track daily_evolution over time. If win rate is trending up (0.55 → 0.70 over 7 days), the model is adapting well to current conditions. A declining trend is a red flag.
Brier Score Benchmarking
A Brier score of 0.21 is good, but compare it to other agents on the benchmarks page. If Kronos has the lowest Brier, its votes are the most calibrated — prioritize them.
