    "prices":"以10万标准耐用品为计价锚，轻装为其40%；方便解释补购与损失，不对应真实枪甲配置。",

    "initial":"现金约支持2—4套标准耐用品；每人另有1套标准装备，期初资产分开记录。",
    "loot":"环境标准路线均值11万宝物，CV0.5；轻装恢复路线5万。需要用同地图、同目的完整出击样本校准。",
    "craft":"4材料可NPC卖8000，加2000制作费，产100发替代购入成本10000；净替代收益0，用于观察渠道替代，不预设套利。",
    "goal":"240000现金相当于20天×每天12000固定补给，再加24材料；日常消耗外需留22万现金，未积足则推迟成长。",
    "activity":"每份180发+4药，恰好覆盖2次标准行动消耗，固定价22000；日8—14发放，前一天至少出击1次且每日补给到账后的现金与物资固定估值低于30万。",
    "market":"只模拟标准/轻装耐用品玩家间成交；固定价、5%费率、NPC标准装备每日180套均为教学机制。无内生价格发现，不能推定实际通胀。",
    "target":"65%/80%等为本轮明确提出的设计目标，非官方指标或行业标准；结果不符时保留失败。"
