 - 浏览器：转出、转入分成两列，按列宽显示完整地址和名称，放不下时先去名称、再用缩写，鼠标悬停显示完整地址和名称。
 - RatDigg 矿机的状态面板加了算力（GH/s）、耗电和成色（烧毁显示“已烧毁”），和矿架一致。
 - 矿机、矿架状态面板里的收款地址在读档、睡觉之后会按标签重新读取，不再显示成“未设置”（地址本来就保存在物品标签里）。
+- 操纵检出：免查线 2% → 15%，斜率 6 → 3。池加深之后，推价幅度 15% 约对应第 0 天 7,000 信用点的现货单（深度随天数增长，免查额度也跟着涨）；超线后被查概率 = 25% + 3 × (幅度 − 15%)，推价约 30%（现货约 14,000）时约 70%。
 - 市场深度：现货池基础深度 50,000 → 120,000，永续成交深度倍数 3 → 5。大额现货单和永续单的滑点明显变小（永续 20,000 名义价值的单边滑点约 3%，原来约 12%；现货买 20,000 价格约涨 36%，原来约 83%）。
