Struct SearchHit 

pub struct SearchHit {
    pub id: IdSpace,
    pub write_cursor: u64,
    pub kind: String,
    pub body: String,
    pub score: f64,
    pub branch: SoftFallbackBranch,

Derives Clone, Debug, PartialEq but not Eq — score: f64 forbids total equality.

Fields

id: IdSpace

C-2 (0.8.19 / TC-8) — the typed, non-null, id-space-total hit id (IdSpace). Was the interim write_cursor: u64 in prior releases; now carries the cross-session-stable key: value is the BARE (prefix-stripped) id, and to_prefixed (== {prefix}{value}) reproduces the pre-swap stable_id byte-for-byte (the real-gold-keying no-op). Governed hits are l:, doc-seeded hits h:, synthetic passages p:. This is the caller-facing identity; the positional write_cursor below is engine-internal book-keeping.

write_cursor: u64

Engine-internal positional cursor (the value id carried before the C-2 swap). Reassigned on every re-projection/re-ingest — NOT cross-session stable, NOT the caller-facing id. Retained because the engine still needs a positional cursor for its own book-keeping (vector rowid mapping, the state='active' filter lookups, RRF recency/importance reweight keys, telemetry result_ids keying, search_expand re-resolution). The SDK bindings do NOT surface it.

kind: String

body: String

score: f64

branch: SoftFallbackBranch

source_id: Option<String>

ce_score: Option<f64>

0.8.5 (EXP-0) — per-candidate cross-encoder score ce_norm = sigmoid(ce_logit) ∈ [0,1]. Some ONLY for hits inside the reranked pool (the top pool_n when the CE model is loaded); None for the unreranked remainder, the rerank_depth == 0 identity path, an empty list, and the no-CE-model soft-fallback. Additive + nullable: it never participates in ranking, so default-path ordering/scores stay byte-stable.
