Struct LocalRetrieverContribution 

pub struct LocalRetrieverContribution {
    pub tablet_id: TabletId,
    pub row_id: RowId,
    pub retriever_id: String,
    pub retriever_kind: Option<String>,
    pub local_rank: u32,
    pub raw_score: f64,
    pub upper_bound_after: Option<f64>,
    pub rls_visible: bool,
    pub weight: f64,
}

One tablet-local hit from a single named retriever (post-RLS).

Multiple contributions for the same (row_id, retriever_id) may arrive from different tablets; the coordinator keeps one contribution per named retriever per global row before fusing.

Fields

tablet_id: TabletId

Source tablet.

row_id: RowId

Row identity (globally unique within the table).

retriever_id: String

Named retriever identity (dense, sparse, minhash, …).

retriever_kind: Option<String>

Optional retriever kind tag for protocol diagnostics.

local_rank: u32

Local 1-based rank within this retriever on this tablet (after RLS).

raw_score: f64

Raw local score (higher is better in the contribution protocol).

upper_bound_after: Option<f64>

Upper bound on the score of any unseen local hit for this retriever after local_rank (None when the tablet is exhausted for this retriever).

rls_visible: bool

Whether this row was visible after RLS (must be true when emitted).

weight: f64

Retriever weight used by RRF (weight / (k + rank)). Defaults to 1.0 when omitted at the merge call site.
