True if the connection edge represents still exists once some
IfcRel* instances may have been deleted. A deduped edge remembers every
IfcRel* that named the same (source, target, type) triple — the edge
survives a delete as long as any one of relationshipId or
shadowedRelationshipIds is still live. Shared by the CLI and MCP
backends so their delete-then-query logic can't drift out of sync with
each other or with the graph's own dedupe (#3782 review).
