- 商品详情页核心卖点:编辑态原是纯静态文本、且 save 不提交 selling_points, 既改不了也存不了;改为可改/删/回车增,save 带 selling_points 一起 PATCH。 - 去掉详情页 name/cat/target/卖点 的「设计稿假数据」fallback —— 商品没卖点 时不再凭空显示护肤品卖点,空值显示「未填写」。 - 出图成功后 submitAndPollAsset 不再整页全量 loadData(十几个 setState 触发 全页大重渲染),只刷当前项目详情 + 轻量刷余额。 - TOS 上传对象加 Cache-Control: immutable 长效强缓存,重渲染不再重拉图。 - products 序列化器内嵌商品图/封面 preview_url(并修回错位的 read_only_fields)。 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
