}

Result of a p99 prediction from the guard.

Fields

y_hat_us: f64

Base prediction (most recent frame time or EMA estimate) in µs.

upper_us: f64

Upper bound of the p99 prediction interval in µs.

budget_us: f64

Frame budget in µs.

exceeds_budget: bool

Whether the p99 upper bound exceeds the budget.

calibration_size: usize

Calibration sample count used.

fallback_level: u8

Fallback level from the underlying conformal predictor (0..=4). Level 4 means frame-guard fixed fallback was used.

state: GuardState

Current guard state.

interval_width_us: f64

Width of the prediction interval (upper - y_hat) in µs.

conformal: Option<ConformalPrediction>

Underlying conformal prediction (if calibrated).
