- 项目卡封面:废弃「项目名关键词→静态 mock 假图」映射(与真实数据脱节,导致全是假面膜图), 改用后端 cover_preview_url(取商品 cover_asset 主图);无商品图 → 干净占位 - 资产库 queryset/summary/facets 补 is_deleted=False:软删资产不再出现在资产库与 tab 计数 (此前 is_deleted 字段在资产库未生效,软删无效) - 单测 AssetSoftDeleteTests:列表 + 计数均排除软删 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
