# Unlike Bolt v5, the Jolt v2 format regrettably removes the legacy
# numeric ID from the response entirely. Therefore we generate it
# here using the algorithm from Neo4j's DefaultElementIdMapperV1;
# the final part of the element ID is identical to the legacy ID
# according to CypherFunctions in Neo4j 5.0-5.25.
# But this may break with future Neo4j versions.
