    "No live multiplayer/combat performance measurement; no publication or server deployment.",
    "After the successful crossing run, added a conservative wait outside the danger circle for an unreachable destination inside it. This final small safeguard was native-compiled, not subjected to another full movement trial. The measured pre-safeguard source and final source are both archived."
