- 字段重命名（旧列弃用保留，启动幂等回填 BackfillPricingColumns）： 入库 unit_price/total_price/total_amount → cost_price/cost_amount/cost_total； 出库同前缀 + 新增 sale_amount（售价小计）/ sale_total（应收）/ profit_total（总利润） - 建单落三值；确认售价联动重算 sale_amount/sale_total/profit_total； 确认进价回填成本后联动重算受影响出库单利润（recalcStockOutProfit） - 出库 List/Get 对 operator/readonly 抹零成本与利润（stripStockOutCost 服务端兜底） - 兼容一版：Create/Update 接受旧 key unit_price 回落（v1.0.87 及之前客户端） - SUM 聚合/价格趋势/导入/种子工具同步切新列；测试全量改名 + 6 个新回归 Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01JJ1g8XV1YhhmHRzhwWEW7o
