    "Four separate machines completing a real internet match and rematch. Neither same-host simulation nor a Wine/container test establishes this.",

    "Native Windows RetroArch/CMD/PowerShell5.1 and a native Linux desktop/frontend session. Windows DLL smoke used Wine; installer tests used PowerShell7 on macOS.",
    "Full stock roster/forms, every move and lifecycle boundary, and worst-case CPU/object budgets.",
    "Physical CPS2 cabinets and four-player Fightcade/GGPO. No hardware address expansion was used; this does not certify cabinet wiring.",
