核心语义反转：receive_cost_delta 为压价点数，收号比例 = 主站参考比例 R + 点数， 点数越大号主收号价越低；买家售价锚定主站参考比例推导，不再随收号价联动。 - 迁移 000072：distribution_sites 新增 receive_cost_delta（旧 receive_ratio_delta 保留只读） - receive_pricing：新增 Normalize/ApplySiteReceiveCostDelta；分站定价买家侧改用 R 锚点（referenceSellerCoinBasePrice），快照写入 site_receive_cost_delta 与 pricing_model 标记 - site_receive：新增 resolveSiteReceiveCostDelta 读取链路，旧 ResolveReceiveRatioDelta 保留 - 分成不变：压价差经结算层 profit 自动进入 35/40/25 三方分成池； 货架自主加价仍 100% 归分站，两条边界均以主站为锚 - 权限对齐旧字段：主站全局管理员与分站操作员均可设置 - 前端三端同步：主站 pricing.ts/usePricingCalculator 买卖解耦试算、 主站后台弹窗改「收号压价」价格语义文案、分销后台 SiteSettings 同步 - 测试：单测锚定 R=43 时 cost_delta=3 → 收号 217.4 / 卖价 263.2 不变 / markup 池 30.6→54.9
