 - 合并知识库导航入口：左侧导航仅保留“知识库”，文档知识库与图知识库在页面 header 中通过同一组轻量切换入口切换，保留原有列表与图谱内容区交互。
-- 抽象页面轻量切换 header：知识库与扩展管理页直接共用 `ViewSwitchHeader`，通过统一切换样式和 actions slot 收敛文档知识库、知识图谱、Tools、MCP、Subagents、Skills 等入口的信息层级；扩展管理各列表的刷新入口下沉到搜索框右侧，并统一搜索框与工具按钮的边框和圆角。
+- 抽象页面轻量切换 header：知识库与扩展管理页直接共用 `ViewSwitchHeader`，通过统一切换样式和 actions slot 收敛文档知识库、知识图谱、Tools、MCP、Subagents、Skills 等入口的信息层级；扩展管理各列表的刷新入口下沉到搜索框右侧，并统一搜索框与工具按钮的边框和圆角，同时强化切换项选中态的边框、阴影与字重层级，提升 header 中当前视图的辨识度。
 - 调整任务中心交互：入口移动到 GitHub 按钮下方，并将右侧抽屉展示改为居中弹窗，减少对主页面布局的占用。
 - 调整 backend Python 工作区依赖边界：将 `backend/package/yuxi` 明确为承载核心运行依赖的业务包，根 `backend/pyproject.toml` 仅保留工作区入口与开发/测试配置，减少依赖职责混淆。
 - 将 `yuxi` 从 uv workspace 成员调整为 `backend/package` 下可独立构建的本地 Python 包，backend 通过 path dependency 以已安装包形式发现依赖，移除对 `PYTHONPATH=/app/package` 的运行时耦合。

 - 修复对话摘要中间件的工具结果卸载链路：摘要触发时改为将大体积 `ToolMessage` 写入当前 agent 可见的 sandbox outputs 路径，修正 `summary_offload` 路径拼接错误、`messages` 触发条件下不会真正裁剪历史的问题，并避免将 system message 重复纳入摘要与最终消息列表；补充对应单元测试覆盖。
 - 调整智能体对话中的工具调用展示：连续工具调用默认折叠为“调用了 N 个工具”的轻量摘要，展开后改为弱化时间线样式，减少工具结果卡片对正文阅读节奏的干扰。
 - 调整聊天首页的智能体切换入口：在无历史对话时，智能体数量 `<= 3` 且 `chat-main` 宽度不小于 `380px` 时继续使用横向 segmented；当智能体数量 `>= 4` 或内容区宽度小于 `380px` 时自动收敛为“当前智能体 + 下拉按钮”形式。
+- 调整对话配置入口与侧边栏头尾交互：输入区配置按钮改为轻量 dropdown 触发器，默认保持透明、hover 才出现背景；下拉中直接提供配置切换、新建配置，以及查看/编辑当前配置的入口。配置侧边栏则移除头部配置切换和新建入口，改为仅显示当前配置名称、可点击星标和关闭图标，并将删除操作下沉到底部保存按钮右侧。
