+
+### Highlights
+
+- Fixed the admin dashboard navigation so the dashboard no longer appears to hard-reload when operators click the current “仪表盘” entry.
+- Smoothed dashboard revisits by caching the last stats snapshot, reducing visible loading flashes even when the page is remounted by navigation flow.
+
+### Improved
+
+- Improved route ownership in [App.tsx](/home/ray/dev/linkong/planet/frontend/src/App.tsx) so the dashboard lives only at `/admin`, while `/` no longer opens the admin dashboard directly.
+- Improved sidebar navigation behavior in [AppLayout.tsx](/home/ray/dev/linkong/planet/frontend/src/components/AppLayout/AppLayout.tsx) by replacing direct link rendering with guarded programmatic navigation that ignores clicks on the already-active route.
+- Improved dashboard data reuse in [Dashboard.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/Dashboard/Dashboard.tsx) by caching the latest stats payload and reusing it on remount before the next refresh cycle completes.
+
+### Fixed
+
+- Fixed the dashboard menu entry switching between `/` and `/admin`, which caused the dashboard route to remount and replay its initial data-fetch/WebSocket bootstrap.
+- Fixed the most visible “reload” symptom on repeated dashboard clicks by preventing no-op navigation and avoiding an empty loading state when cached dashboard stats are available.
