Enum SourceOp 

pub enum SourceOp {
    Vector,
    Keyword,
    Fused,
    Reranked,
    Graph,
    Tree,
}

What kind of operator produced a RawHit. RRF fusion groups raw hits by this tag so per-branch rankings stay isolated when computing 1 / (k + rank_i).

Plan 02-03 added Reranked (cross-encoder pass output). Plan 03-02 added Graph (anchored graph traversal output). The Fused variant marks a RawHit that has already been through a fuse_rrf operator (so fuse_rrf of a fuse_rrf re-fuses on the fused tag, treating it as a single branch).

Variants

Vector

Keyword

Fused

Reranked

Graph

Plan 03-02 (D-15): Graph::anchored operator output. RRF fusion groups Graph hits as a separate branch from Vector/Keyword so reciprocal-rank contributions stay isolated. Per-hit score = 1.0 / (1 + bfs_rank) for rank-stability across hops (rank 0 → 1.0, rank 1 → 0.5, …).

Tree

N5/B2 (RAPTOR tree retrieval): leaf-chunk hits descended from a matched community summary node. The operator searches the "communities" vector index, then walks Community.members to collect leaf-chunk IDs. Score is inherited from the parent community’s cosine similarity. Hydration resolves chunk text normally — the id bytes are chunk ULIDs.
