Unlike /predict which returns the median-averaged prediction, this returns the full empirical distribution from sample_count independent inference paths. At each prediction step you get p05-p95 percentiles for close price, plus the final return percentile distribution. This is the true probabilistic output of Kronos — agents can use it to compute Value-at-Risk, confidence intervals, or any custom decision rule. Price scales with timeframes: $0.01 per TF, capped at $0.04 for all 5.
