CosineScorer

mnemo_core::query::evidence

Struct CosineScorer 

Source 
pub struct CosineScorer;
Expand description

Default scorer: cosine similarity of candidate vs query embedding.

When either embedding is missing or degenerate (e.g. the engine runs NoopEmbedding, whose vectors are all-zero), it falls back to the candidate’s fused retrieval score so the budget stays usable without a real embedder.
