Replace per-community and per-node query loops with precomputed aggregate queries + executemany batch inserts. community_summaries: 2 queries per community -> 3 total - single GROUP BY query for top symbols across all communities - single flat SELECT for all file paths across all communities - executemany batch insert replaces per-community INSERT risk_index: 3 queries per node -> 3 total - single GROUP BY query for all caller counts - single SELECT for all tested qualified names - executemany batch insert replaces per-node INSERT On a repo with ~17k nodes and ~500 communities this reduces ~54,000 SQL round-trips to ~6, eliminating the build hang.
