- 资产 preview_url 从「逐图签发预签名 URL」改为虚拟主机式公读直链 (https://{bucket}.{host}/{key})。桶公读已验证免签可访问;直链稳定可被浏览器/CDN 缓存,而签名链每次都变、1h 过期反而打不到缓存。boto3 也移出序列化热路径。 - allNotifications 不再逐页翻全部(原 O(N) 随消息增长拖慢每次刷新),只取首页 100 条 (侧边栏徽标 unread_count + 团队动态仅展示最近 6 条已足够);「共 N」改用后端真实 count。 - perf-probe:page_size 由 API 级硬闸确定性守住后,浏览器端「资产翻页」降为提示 (翻 1~2 页是资产真超 200 的合法分页,仅 ≥3 页才疑似 page_size 失效)。 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
