Enum RankReason 

pub enum RankReason {
    ExactTopic,
    Recency,
}

Why the provider ranked a record into the contribution (spec §6.5, §10.4 explainability). Minimal closed set until task B1.

Variants

ExactTopic

Exact topical match against the recall query.

Recency

Recency-weighted selection.

Implementations

impl RankReason

pub fn phrase(self) -> &'static str

Plain-words /memory why phrase (task B5, spec §10.4). Exhaustive match with NO wildcard arm — adding a wire variant without a phrase is a compile error, never a silently unexplained selection.
