pub fn missing_current_facts<'a>(
index: &KnowledgeEmbeddingIndex,
knowledge: &'a ProjectKnowledge,
cap: usize,
) -> Vec<&'a KnowledgeFact>Expand description
Current facts that have no vector in the side-car index, most valuable
first (same ordering as embeddings_reindex: confidence, then recency).
Engine-free so the selection is unit-testable with raw indices.
