Struct ServerProbePolicy 

pub struct ServerProbePolicy {
    pub probe_count: u32,
    pub min_hit_rate_pct: f32,
}

Policy for probing backup servers before committing all missing articles to them.

When an article cascades past the highest-priority server, the dispatcher sends a small sample of missing articles as “probes” to the next-priority server instead of immediately routing the full backlog. Only if the probe hit-rate meets the threshold is the server approved for all remaining cascade articles. If not, the server is rejected for this job and remaining articles cascade further or fail fast.

This avoids the O(N × servers) cascade cost for fail-heavy NZBs where backup servers are equally unhelpful (e.g. DMCA-removed or out-of-retention content that no provider carries).

Fields

probe_count: u32

How many articles to probe before deciding whether a backup server is useful for this job. Default: 10.

min_hit_rate_pct: f32

Minimum percentage (0–100) of probed articles that must succeed for the server to be approved. If the hit-rate falls below this, the server is rejected for this job and the remaining cascade articles skip it. Default: 10.0 (at least 1 out of every 10 probes must succeed).
