pub async fn sync_references(
store: &dyn IndexStore,
paper: &Paper,
) -> Result<(Vec<Paper>, usize, usize)>Expand description
Fetch, persist, and return the OpenAlex references of paper. Idempotent:
referenced papers dedupe against library entries by OpenAlex id then DOI,
and citation edges dedupe on their paper-id pair. Returns the resolved
reference papers, how many edges were newly inserted, and how many papers
were newly ingested.
