Struct SparseTermDf 

pub struct SparseTermDf {
    pub term: String,
    pub df: u64,
}

Per-shard raw BM25 sparse inputs, returned alongside sparse_inputs when return_inputs=true so the gateway can rescore every candidate against CORPUS-WIDE statistics (global N / df / avgdl) instead of fusing scores that were each computed with shard-local statistics and so are not comparable.

sparse_local_n / sparse_local_sum_dl are this shard’s contribution to the global document count and document-length sum (the gateway sums them to get global N and avgdl). sparse_term_df is this shard’s per-query-term document frequency (summed to global df). sparse_doc_inputs carries, per candidate doc, its length and its per-term term frequencies so the gateway can apply the exact BM25 formula with the aggregated stats.
