 * 全流程模拟测试：采购商下单 → 分享链接 → 纺织厂确认 → 生产流程 → 分批次入库
 * 
 * 测试场景：
 * 1. 采购商创建产品和生产计划
 * 2. 生成分享链接给首次合作的纺织厂
 * 3. 纺织厂点击链接并确认导入
 * 4. 纺织厂逐步确认生产流程节点
 * 5. 分批次坯布入库（3批）
 * 6. 验证数据完整性和一致性
 * 
 * 前置条件：
 * - 示例布行 (11111111-1111-1111-1111-111111111101) 和示例纺织厂 (11111111-1111-1111-1111-111111111102) 已存在
 * - 两家公司之间无合作关系（首次合作场景）
 * - 坯布仓库 (22222222-2222-2222-2222-222222222202) 已存在
