- 实体/双 SQL 加列+idx_att_ref;upload 增 scene 白名单(banner/link/site) - AttachmentService 新增 markUsed/release/markSiteConfigUsed(webUrl 反查,幂等) - 未使用=articleId 与 refType 均空;page 返回 unusedCount(前后端同步改名无兼容别名) - Banner/Link 保存先解引用再回写(换图旧图回未使用);Site 配置 logo/favicon 引用回写(@Lazy 解循环依赖) - 新增13例(Attachment6/Banner3/Link2/Site2)+既有语义断言更新;mvn -o test 全绿
