2026-10-05: protocol-cpu.json (server3) and protocol-cpu-spark.json (spark) are WITHDRAWN without running.
Neither machine had a quiet window (server3 load 40-144 from other users; spark fully used by other builds), and the same engine met the target on stated hardware under protocol-cpu-desktop-2.json (1.69e9 life-months/s at 250M lives, identical on all 10 seeds).
No run was made under either protocol, so neither has a result.
