Struct Explanation 

#[non_exhaustive]
pub struct Explanation {
    pub trace: QueryTrace,
    pub per_hit: Vec<PerHitExplain>,
}

0.8.8 EXP-OBS (Slice 5) — the opt-in retrieval explanation payload returned behind search_explained (the explain=true surface). Built from the engine’s OWN fusion/rerank machinery (fuse_three_arms per-arm ranks, ce_rerank blend components) — no parallel machinery (R-OBS-3). Carries a query-level QueryTrace plus a per-hit breakdown parallel to (and in the same order as) SearchResult.results.

Derives Clone, Debug, PartialEq but not Eq — scores are f64.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

trace: QueryTrace

per_hit: Vec<PerHitExplain>
