Struct RetrievalStats 

pub struct RetrievalStats {
    pub served: u64,
    pub with_hit: u64,
    pub hit_rate: Option<f64>,
    pub avg_top_score: Option<f64>,
}

C1 — retrieval hit-rate. Populated once C7 lands context.served events; all fields are stub values / None for now.

Fields

served: u64

Total context.served events in the window (C7).

with_hit: u64

Served events whose bundle contained ≥1 capsule (C7).

hit_rate: Option<f64>

with_hit / served; None until C7 populates served.

avg_top_score: Option<f64>

Average top_score across served events (C7).
