 - 现货柜台：每周刷新一批违禁品（游戏已有的 32 种，低 / 中 / 高三档随声望 10 / 40 / 80 放开；件数 4 + 声望/40），价格 = 游戏基础价 × 1.3，只收 PSC / CRT / CRA / Ponero，不收 CRC。付出去的币连同按比例的污点留在卖家那边，货放进储藏区，不带赃物标签。
 - Ponero 兑换处（声望 ≥ 30）：任意币兑入 Ponero 时这部分价值的污点留在原地，兑入、兑出各收 8%，每天额度 1000 信用点；Ponero 价 = PSC × 0.5。从 Ponero 兑出的币在出金审查里按"刚出混币器"加重。
 - 游戏内验证：声望 75 时上架 5 种；用 CRT 买一把左轮 312 点，余额 3000 → 2688，污点 2000 → 1875（按付款占钱包的比例）；5 PSC 兑入得 9.2 Ponero（500 × 0.92 / 50），当天额度剩 500。
-- 还没做：订单（托管、送货、死投点）、平台跑路、包裹截获、蜜罐、受控交付。
+- 订单：黑市页新增"订单"和"我的订单与情报"。目录每周刷新，4 个卖家（成交数、好评率公开，15% 是骗子，多半是新号，也有刷过好评的老号），价格 = 基础价 × 0.85。托管多付 5%，收货后放款，卖家跑路时退款（污点与成本一并还回，不能借退款洗钱）；提前放款再打九折，只有成交 ≥ 30 的卖家接受，骗子拿钱就跑。
+- 配送：送货上门 3 天，到货后开店时快递员作为顾客上门，对话结束把货放进储藏区；死投点 2 天，到货后晚上去垃圾场，货进外出背包。上门被截获 8%，死投 3%，死投另有 12% 被别人先挖走；镇压期间到期顺延、截获 +15%。
+- 平台跑路：每晚概率 0.2% + 在途款项每万信用点 0.4%（封顶 5%），跑路后在途款项归零、目录与现货清空、入口关闭 10 天。论坛情报：骗子卖家有一半概率被人点名，跑路风险升高时出现提币变慢的帖子。
+- 游戏内验证：下单后在途显示在"我的订单"；过夜到期，两单到货，一单骗子卖家托管退款（CRT +143，污点 +57）；快递员对话走完，货进储藏区，快递员自动离开。没有在游戏里验证：死投点取货（要去垃圾场）、平台跑路与截获的实际触发（只有单元测试）。
+- 还没做：蜜罐、受控交付（第三批）。
