 测试使用独立临时站点及模拟构建器，不发布真实文章；本次没有人工批准生产稿件，AI服务尚未配置。
 
 2026-10-25生产接通：经白色机完成Git推送/明确提交部署；完整相册1篇/6图7526412字节进入ATOM私有存储，TTC签名预览成功，稿件停在awaiting_ai，AI仅预留接口。原TTC88篇文章未变，无人工批准或真实发布。三方当前提交、备份及图片流式响应修复见ATOM专题；已完成服务器侧验收，未做线上页面验收。
+
+2026-10-26扩展：ATOM为主要文章管理入口；AI仅预留，当前人工确认发布。新增独立HMAC频道拉取、三边删除墓碑/回执及失败恢复；具体接口、日期排序/完全重复折叠、测试和生产实际状态以ATOM内容中心专题为唯一正文。
