Expand description

Configuration for the VOI sampling policy.

Fields§

§alpha: f64

Significance level α for the e-process threshold (W* = 1/α). Default: 0.05.

§prior_alpha: f64

Beta prior α for violation probability. Default: 1.0.

§prior_beta: f64

Beta prior β for violation probability. Default: 1.0.

§mu_0: f64

Baseline violation rate μ₀ under H₀. Default: 0.05.

§lambda: f64

E-process betting fraction λ. Default: 0.5 (clamped).

§value_scale: f64

Value scaling factor for VOI. Default: 1.0.

§boundary_weight: f64

Weight for boundary proximity. Default: 1.0.

§sample_cost: f64

Sampling cost (in normalized units). Default: 0.01.

§min_interval_ms: u64

Minimum interval between samples (ms). Default: 0.

§max_interval_ms: u64

Maximum interval between samples (ms). 0 disables time forcing. Default: 250.

§min_interval_events: u64

Minimum events between samples. Default: 0.

§max_interval_events: u64

Maximum events between samples. 0 disables event forcing. Default: 20.

§enable_logging: bool

Enable JSONL-compatible logging.

§max_log_entries: usize

Maximum log entries to retain.
