Enum SearchArm 

pub enum SearchArm {
    Hybrid,
    Bm25Only,
    Explore,
}

Which retrieval pipeline an eval arm exercises (#686 default-flip decision).

Variants

Hybrid

Full default pipeline: BM25 + dense embeddings + SPLADE + RRF + rerank.

Bm25Only

Pure lexical BM25 — the conservative lower bound of the lean (dense_enabled = false) path, which additionally keeps graph proximity, reranking and SPLADE on top. If pure BM25 already matches hybrid, the real lean path is ≥ that, so flipping the default cannot regress quality.

Explore

FastContext-style ctx_explore: a bounded multi-turn loop (BM25 anchor + static graph BFS + AST symbols) returning path:line citations. Reported as a peer arm so the scorecard shows its recall and its citation-level token footprint — the value prop is locating the answer across files at a fraction of the tokens a body-read would cost.
