Hierarchical status codes returned by the Neo4j Bolt protocol and Cypher engine. Each code follows the format Neo.{Classification}.{Category}.{Title}, where Classification indicates severity (ClientError, ClientNotification, DatabaseError, TransientError), Category groups related conditions, and Title identifies the specific condition.
