EvidenceBudget

mnemo_core::query::evidence

Struct EvidenceBudget 

Source 
pub struct EvidenceBudget {
    pub max_evidence: Option<usize>,
    pub stop_when_sufficient: bool,
    pub sufficiency_threshold: f32,
    pub scorer: ScorerKind,
}
Expand description

Serializable per-query evidence budget.

Attach via RecallRequest::evidence_budget. All fields are optional knobs; the zero-config default (EvidenceBudget::default) caps nothing and never early-stops, so an explicitly-Some(EvidenceBudget::default()) request still behaves like the legacy path.

Fields§

§max_evidence: Option<usize>

Hard cap on the number of evidence chunks returned. None leaves the count bounded only by the recall limit.

§stop_when_sufficient: bool

When true, stop accumulating evidence as soon as the running sufficiency score clears [sufficiency_threshold]. The caller gets the smallest prefix that clears the bar.

§sufficiency_threshold: f32

Cumulative sufficiency score the selected set must reach before early-stop fires. Scores are summed across selected chunks, so for a cosine signal in [0, 1] a threshold of 0.8 is cleared by one 0.85 chunk or two 0.4/0.45 chunks. Ignored when stop_when_sufficient is false.

§scorer: ScorerKind

Which scorer computes the per-chunk relevance.

Implementations§

Source

pub fn capped(max: usize) -> Self

Convenience constructor: cap at max chunks, no early-stop.
