Struct GraphScoringConfig 

pub struct GraphScoringConfig {
    pub weight_semantic: f64,
    pub weight_hotness: f64,
    pub weight_utility: f64,
}

Scoring weights for utility-weighted semantic search.

The final score for a retrieved entity is computed as a linear combination of three signals:

score = weight_semantic * similarity
      + weight_hotness  * hotness
      + weight_utility  * utility_score

Defaults (0.45 / 0.30 / 0.25) match the original hard-coded values, so omitting the [graph.scoring] section from .recall-echo.toml produces identical behavior to pre-v3.9.0 recall-echo.

Weights are not constrained to sum to 1.0 — the scoring function does not normalize. Callers that change these should calibrate against their own retrieval outcomes; see utility-feedback-loop-spec.md in pulse-null.

Fields

weight_semantic: f64

Weight applied to cosine similarity. Default 0.45.

weight_hotness: f64

Weight applied to the recency/access hotness signal. Default 0.30.

weight_utility: f64

Weight applied to the utility score (outcome-feedback EMA). Default 0.25.
