 - 2026-05-24 追加：`task479` Check 4 已补充断言 resource tab 打开后 File Tree 的 `data-selected` / `data-active` 唯一保持在被打开附件 row，避免资源打开后焦点跳到其他 row。
 - 2026-05-24 追加：`task479` Check 3 已补齐缺失真实附件后的点击行为断言。根因是 resource tab 已创建并标记 error 后仍返回 `false`，外层附件点击逻辑因此执行 `window.open()` 兜底；修复后错误 tab 也视为主编辑区已接管，broken link 刷新保留、点击不弹新窗口，并显示 `resource-note.md` 的 resource tab error state。
