 - 挖矿报告并进 Web3 页的"挖矿"子页，终端顶栏不再有"报告"。
 - 游戏内验证：受控交付的对话与两个选项显示，拒签后快递员离开、下一位顾客进来。没在游戏里验证：签收的罪证、蜜罐与落网的夜间追查（只有单元测试）。
 
+- 货架重做：违禁品池只留能转手的货（枪械、钥匙卡、密码解序器芯片、爆炸物），弹药、毒品、药品、化学品、种子全部移除；高科技物品池换成矿机能用的东西（7 种系统模组、能量电池、能量阵列、高级模组提取器、矿架）；显卡与高科技各占 30%，高科技不再需要中档声望。
+- 玩家出售：黑市页新增"出售"子页。储藏区里的违禁品、高科技物品和显卡做成货架，选标价倍率 0.6–1.8（相对参考价；显卡按标称型号与成色）上架，收 5% 上架费。每晚按期望天数成交：≤0.9 倍 1 天，1.0 倍 2 天，1.8 倍 14 天，之间插值。成交扣 8% 抽成，货款托管 3 天后以 CRT 进钱包。货款带污点的概率和比例随倍率从 20%/20% 涨到 90%/80%。
+- 出售的风险：假卡有 50% 被买家看穿退货，好评 −10（好评影响成交速度，每笔成交 +1）；平台跑路时上架的货和未放款的货款都没了；蜜罐期间成交的货款和近期买家落网会被追查记罪证；镇压期间平台不成交。"我的订单与情报"页多出"我的上架"，可以撤下。
+- 游戏内验证：货架显示显卡、模组、能量电池；买一张卡后出售页列出储藏区里的货，上架（标价 400，上架费 20），过夜成交（货款 368），3 天后到账（CRT 2804 → 3172，这次随机没带污点）。没有在游戏里验证：假卡退货、跑路时的出售损失（只有单元测试）。

 ### 第三阶段：数值调优（进行中）
 
 - 混币器每轮手续费 6% → 4%；用币付款的顾客概率提到上层 30%、黑市 50%、革命派 50%、下层 25%，并多付 12%（溢价只加在币数上，污点仍按货值算）。
