 - 订单改成商家货架（用户意见）：黑市页"订单"改名"商家"，每周从 6 种类型里抽 5 家（全新矿卡经销商、二手矿卡贩子、模组高科技、军火、证件芯片、药物），另有 25% 的周出现一家大宗商家（库存 10–25 件、价格系数 0.55–0.75、送货 6 天）。每家有自己的价格系数（订单价 = 基础价 × 系数，一般 0.70–0.95，全新卡 0.85–1.00，二手卡 0.65–0.90），每家 4 种货、库存 3–6 件。一次订 5 件以上 95 折、10 件以上 9 折。界面：件数按钮 ×1 / ×5 / ×10，商家按钮，所选商家的货架。药物（药片、梦尘、管制化学品）只在药物商家和大宗商家出现，也能转手出售。每周货架总值在游戏里抽样 60 周平均 13.2k（目标 1.4 万）。
 - 商家类型扩到 18 种 + 大宗（用户意见，对照游戏的物品目录和玩家职业）：全新矿卡经销商、二手矿卡贩子、矿架与能源、模组、军火（枪、手雷、炸药、刀具、电击枪）、枪匠配件（枪械配件、3D 打印芯片与模组、枪械零件）、证件芯片、药物（药片、注射器、血袋、手术工具）、化学品（化学用品、助熔剂、化学设备模组、量筒试剂瓶）、酿酒（酵母、荧光莓、啤酒、酒瓶）、水培农场（种子、水培模组、植物分析仪）、养殖（鱼卵、鱼子酱、循环水养殖系统、血清、屠宰机）、矿工（矿石、金属锭、电子元件、拾荒扫描仪）、水务（滤水、净水、储水、检测）、仓储（走私暗格、储藏区扩建、军用背包）、工具（涡轮增压器、等离子切割机、X 射线扫描仪、心智重编程器）、奢侈品（香水、精华液、香烟）。每周 7 家：2 家从矿卡 / 矿架 / 模组 4 类里抽（保证矿工路线总有货），其余 5 家从其余类型里抽；每家 3 种货，库存 2–5 件，单件基础价超过 4000 的不上。游戏里抽样 60 周货架总值平均 13.2k（目标 1.4 万）。药物改成并入药物商家，现货柜台的货不变。所有货都能转手出售。
 - 尖端店铺与个人卖家（用户意见）：贵货（单件基础价 ≥ 2000：超科技涡轮增压器、超科技储藏区、心智重编程器、顶级显卡等）不再被一刀切掉，改由"尖端店铺"卖：每周只有 15% 的概率出现，2 种货、库存 1–2 件、价格系数 0.85–1.00、送货 5 天；顶级全新显卡也在这里。个人卖家：每周固定 2 位，什么都卖（可能是药、模组、显卡、仍有 10% 混进贵货），每件价格系数各自随机 0.50–1.20（捡漏或被宰），库存 1–2 件，是骗子的概率 25%，都是新号所以只接受托管。常规商家仍只卖基础价 ≤ 4000 的货。
+- 黑市标签整理（用户意见）：原来的"现货柜台 / 商家 / 出售 / 我的订单与情报 / Ponero 兑换处"改成三个对称的标签"买货 / 卖货 / 订单"。买货页里平台现货是第一家卖家（"[平台] 0x…"，立即到货，选它时不显示托管 / 提前放款），后面是各商家，件数按钮 ×1 / ×5 / ×10 现货也适用（一次买多件走一次付款确认）；论坛情报放到买货页最下面；订单页分"买入"（订单）和"卖出"（上架、改价、撤下）上下两块。Ponero 不再是黑市里的标签：并进 Web3"交易"页的右栏，作为一个带"[匿名币]"标签的通用兑换块（选 PSC / CRT / CRA，兑入 / 兑出，要黑市声望，仍有每日额度和手输地址确认）。游戏内验证：新的三个标签和平台现货货架、订单页、交易页的 Ponero 块，兑入进入付款确认。
 - 定价改成直接输价格（用户意见）：点货架上的"上架"或"我的订单"里的"改价"，出现"设定标价"页，显示参考价（真实价）和输入框；×0.6–×1.8 档位只是帮忙把价格填进输入框，也可以手输整数，输入后显示"标价 83（×1.38）"；价格要在参考价的 0.6–1.8 倍之间（显示可输范围），确定后走付款确认（上架费 5% / 改价费 2% 按新标价算）。成交速度和货款污点都按 标价 ÷ 参考价 的实际比例连续计算（不再只有档位）。"我的订单"里每件上架的货显示"参考 60　标价 83（×1.38）"，下面是"改价"和"撤下"。出售页顶上的档位按钮保留，作为默认倍率（预填价格、"全部上架"用）。游戏内验证：档位填价（×1.5 → 90）、手输 83（×1.38，上架费 5）、范围外（200）被拒并提示 36–108。
 - 自己的储藏区和背包不再出现在可上架的货里，有内容的容器也不行（之前储藏区（扩建）会被列出来，上架会把里面的东西一起带走）。
 - 上架后可以改价（用户意见）："我的订单与情报"页每件上架的货下面一排倍率按钮（0.6–1.8，当前的带方括号）和"撤下"，点倍率先走付款确认（改价费 2%，`BmRepriceFee`，手输平台地址），标价按参考价重算，成交概率按新倍率走，上架日不变。游戏内验证：0.6 倍的 RTX 70 改成 ×1.2，改价费 12，标价 600。蜜罐基础概率维持 1%（模拟里进取策略罪证 ≥ 300 约 48 天，用户认为可接受）。
