 "_note": "Raw per-run output behind the multi-node full-topology baseline in docs/efficiency.md. Produced by benchmarks/nexmark_compare/cloud/full-run.sh; not hand-edited. One row per run: one engine, one query, one trial, parallelism 12 across three worker nodes, CPU and memory summed over every engine node (control + 3 workers).",
 "_premise": "NEW BASELINE, not comparable row-for-row to the split-rig rounds: 5 nodes (control ccx13 + 3x ccx23 workers + ccx23 broker), parallelism 12, every keyed shuffle crossing real hosts. taskmanager.memory.process.size EXPLICITLY 6g (image default is 1728m, which every earlier round ran) - required, because at 1728m Flink's q18/q19 source stalls deterministically (~1.08M of 9.2M) and never drains; at 6g it drains. Flink's memory column therefore reflects the raised setting and must not be compared to earlier rounds. clink workers ran --slots=48 (a scheduling cap; 16 made q5's 120-task plan unschedulable).",
