pub fn edges_among(conn: &Connection, ids: &[&str]) -> Result<Vec<GraphEdge>>Expand description
Read edges whose source AND target are both in ids — the induced subgraph
over a candidate node set.
Used to build the candidate subgraph for PageRank boosting in
smart_recall. ids.len() must stay under
SQLite’s bind-variable limit (999 by default); smart_recall caps at 100.
