- delete_product 补 count_refs 引用检查（业务明细+发货明细 RESTRICT 外键）与并发窗口 IntegrityError→400 兜底（customer 先例同构）， docstring 与两个 api 层过时注释同步更新 - 产品 schema 复用 schemas/business._check_amount：sale_price 走 (PRICE_MAX, scale=4)、stock_quantity 走 AMOUNT_MAX——此前私写 _parse_non_negative 不查小数位与容量，5 位小数被 Numeric(14,4) 静默截断（舍入即算错钱）；新增 6 个秒级 schema 单测锁定口径 - 全局注册 IntegrityError handler：漏补引用保护的删除类操作收敛为 400 通用文案（e2e 撞见一个补一个的模式无法保证全覆盖），完整 异常记日志；rating/customer 的「非 1062 按 500」注释同步更正 Co-Authored-By: Claude Code <noreply@anthropic.com>

守：产品 sale_price/stock_quantity 若私写校验不查小数位与容量，5 位小数
