 "notes": [
  "Seen tasks: the V2 core was trained on these three Arena games. The eval seeds were sealed and played once.",
  "Timing: V2 was played with the nominal 1-tick reply (the decision for tick t applies at t+1), justified by its measured latency gate L. The V1 and Jev numbers come from live realtime records, where a slow reply lands later.",
  "Snake Rush: V2 plays the SDK Snake search pack (20,000 simulations, horizon 12), which does not read the learned core. A predeclared rule chose it from dev seeds only, before the sealed look.",
  "Booster Gauntlet: V2 landed the first hop on 23/24 seeds; V1 on 0/24 and Jev on 0/24 (K3 = 0), so V1 vs Jev is all ties there. Game Arena v3's Board 1 documents V1's Booster pattern: flying under control until the first hop's landing deadline, without landing.",
  "Rotorwash-Ramp is a float64 engine. Re-checked here under Rosetta (no AVX/FMA), the Jev records recompute the recorded score on 24/24 seeds but replay state-hash-exactly on only 8/24. The recording job's own replay check on its x86-64 host passed on every seed. The release's V1 Rotorwash-Ramp check needed a real x86-64 CPU for the same reason.",
  "Not comparable with the Board 1 leaderboard below: different seeds (the release's sealed eval seeds here, Board 1's screen seeds there), Rotorwash-Ramp and Booster Gauntlet are scored by their K3 scores here and by survival time there, and Jev here is the single-stream re-play."
