+
+### Highlights
+
+- Refined the BGP AI brief operator workflow so the tab now stays compact and metadata-focused, while the full Markdown brief opens in a bounded modal that respects the repo’s single-screen layout rules.
+
+### Improved
+
+- Improved [frontend/src/pages/BGP/BGP.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/BGP/BGP.tsx) by turning the brief action row into a clearer `历史简报下拉框 + 查看 + 生成` flow, keeping inline metadata visible in the tab while moving full Markdown reading into a dedicated modal workspace.
+
+### Fixed
+
+- Fixed [frontend/src/index.css](/home/ray/dev/linkong/planet/frontend/src/index.css) and [frontend/src/pages/BGP/BGP.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/BGP/BGP.tsx) so the BGP brief modal no longer spills below the viewport; long brief content now scrolls inside the modal body instead of extending past the visible screen.
