Inputs required to check quality gates.

This is a stateless struct that contains all the information needed to check quality gates, avoiding the need for mutable state or time tracking.

Fields

posterior: &'a Posterior

Current posterior distribution.

prior_cov_marginal: &'a Matrix9

Marginal prior covariance matrix Λ₀^marginal = 2σ²R (for ν=4). This is the unconditional prior variance of δ under the t-prior. Used by Gate 1 for the KL divergence check (spec §3.5.2).

theta_ns: f64

Effect threshold θ in nanoseconds (user’s requested threshold).

n_total: usize

Total samples per class collected so far.

elapsed_secs: f64

Elapsed time in seconds since adaptive phase started.

recent_kl_sum: Option<f64>

Sum of recent KL divergences (last 5 batches). Pass None if fewer than 5 batches have been collected.

samples_per_second: f64

Samples per second (throughput from calibration).

calibration_snapshot: Option<&'a CalibrationSnapshot>

Calibration snapshot for drift detection. Pass None to skip drift detection.

current_stats_snapshot: Option<&'a CalibrationSnapshot>

Current stats snapshot for drift detection. Pass None to skip drift detection.

c_floor: f64

Floor-rate constant (c_floor) from calibration. Used to compute theta_floor(n) = c_floor / sqrt(n).

theta_tick: f64

Timer tick floor (theta_tick) from calibration. The floor below which timer quantization dominates.

projection_mismatch_q: Option<f64>

Projection mismatch Q statistic (r^T Σ^{-1} r). Pass None if not yet computed.

projection_mismatch_thresh: f64

Projection mismatch threshold from bootstrap calibration.

lambda_mixing_ok: Option<bool>

Whether the Gibbs sampler’s lambda chain mixed well (v5.4). None if not using Gibbs sampler (mixture mode). When Some(false), indicates potential posterior unreliability.
