Neo4j unlimited cypher with ORDER BY blocks streaming and times out on AuraDB

A Hono endpoint streamed graph data from Neo4j to the browser via NDJSON. Phase 1 (25k nodes) streamed fine; phase 2 (67k edges, no LIMIT) returned zero records to the client and the connection closed mid-response. Locally against a Docker Neo4j it worked; against managed AuraDB it failed every time. Result: client received the full nodes phase, then 'done' was never emitted and the renderer rendered an empty graph.
