- 图源映射统一:热点采集与 Pinterest 模式均走 config.product.mark_dirs 配置,按任务序号随机抽模特图/平铺图 - 商品产地固定:统一为「中国大陆」+「产地省份=广东省」(不再读站点/字典映射) - 模板 SKU 字段检测:按建议售价同一套路检测 SKU分类/SKU数量/SKU数量单位,必填时填入单品/1/件 - 多模态分析提示词可配置:prompts/pinterest_analyze_system.md + user.md,支持国家覆盖,不丢文件回退内置 - 自定义图片模式:新增 pinterest_custom_load_node,图片数量硬校验,选品清单 ≤ 有效图片数 - 模板导出优化:写入前按货号末 3 位升序排序,不再产生空白 xlsx - 修复 v90 project review 10 项(503 致命终止、线程安全、原子写入等)
