 # 图片生成无法删除失败图片 BUG TODO
 
+> 最终状态：已完成（2026-07-16）
+>
+> 补充修复：三种图片生成模式的单图删除、失败格重跑与页面回填已统一。重跑图会绑定其替代的失败格；删除该补图后，对应失败格不会在刷新或切换页面后复活。历史补图记录也按原始批次张数回显，不会出现“最多 4 张却显示 5 张”。
+>
+> 验证：后端重跑关联回归测试通过；前端 TypeScript 与生产构建通过；单图仍进入原有资产垃圾桶，整批删除与“图片异常批次”流程保持不变。
+
 > 状态：Step 2 方案已确认，待进入实施
 > 页面：图片生成入口 `/asset-factory` 所进入的模特上身图、平台套图、图片创作
 > 协作规则：一次只执行一个 Step；在确认问题表现前，不排查、不修改代码。
