+- 网页工作台进一步回归清爽白色界面：助手回复改为开放式文档流，工具调用与结果合并成可展开的紧凑活动项；同时修复语音输入停止后按钮仍显示“停止”的问题。
+
 ## 0.60.10 — 2026-07-29
 
 - 网页工作台恢复清爽的中性白色配色，助手回复回到左侧阅读轴；手机端进一步缩小顶部页签、操作按钮和输入区，并移除默认的文件保存位置提示，为对话正文留出更多空间。

 ### 2026-07-29
 
+- **07-29 / 0.60.11 / Web 对话流去卡片化 + 工具活动合并 + 语音状态修复**:工作台背景统一以纯白为主，浅灰仅保留在 hover、代码块等局部状态；助手历史/实时回复移除重复角色标签、大卡片边框、左色条与运行态红框，改为左锚开放文档流。历史态按 `tool_call_id` 将 assistant 调用与 tool result 合并，实时态复用同一 details 原位更新结果，统一为默认折叠单行活动项（执行中/成功/失败状态明确），产物 chip、媒体 banner 与后台进程活化继续保留；顶部 task progress dock 的位置和逻辑未改。另修短按语音转连续录音时直接覆写按钮 `textContent`、销毁 SVG/label 导致停止后无法恢复“语音”的问题，收口为 class/label/ARIA 状态函数。相关 Python 24 项 + Node 5 项及 JS 语法、diff 格式检查通过；无 API、schema、migration 或依赖变化。
 - **07-29 / 0.60.10 / Web 工作台移动端空间优化**:根据第二轮手机实图反馈把暖白/浅米灰改回中性白色，桌面助手回答、工具卡与任务进度恢复左侧阅读轴；手机端压缩顶栏、Tab、任务操作区、模型区、消息间距和 composer，高频操作键由 44px 收至 40px、输入框最低高度由 64px 收至 52px，并隐藏空闲态“请选择文件保存位置/就绪”占位行，运行、上传与错误等有效状态提示继续按需显示。相关 Python 21 项 + Node 5 项及 JS 语法、diff 格式检查通过；无 API、schema、migration 或依赖变化。
 - **07-29 / 0.60.9 / Web 工作台视觉复核修正（桌面 + 手机实图）**:据上线截图把冷蓝灰改为暖白/浅米灰；任务与文件行恢复明确分隔，助手消息收进居中 52rem 文档型回答块，工具与进度对齐同一阅读轨道；同时修掉 `task_progress`-only assistant 被过滤工具后仍留下空“助手”壳。手机端 composer 改为独立状态行 + 3 个 44px SVG 图标键 + 发送键，缩短 placeholder、加入安全区并压缩操作/模型区；录音与润色状态改只更新 label/ARIA，不再覆盖 SVG DOM。相关 Python 21 项 + Node 5 项及 JS 语法、HTML/SVG 结构、CSS 括号检查通过；无 API、schema、migration 或依赖变化。
 - **07-29 / 0.60.8 / Web 工作台 Visual Polish v1**:新增零构建 `web/static/ui.css` 作为内部轻量视觉基础层，集中颜色、间距、圆角、阴影与 focus/disabled 等控件状态；收敛三栏层级、任务/资源导航、对话正文与工具过程块、输入区、文件栏、modal/toast 及 ≤640px 触控尺寸，不改 DOM 契约、API 或业务交互。新增 CSS 文件接入、MIME 与 `no-cache` 回归测试；相关 Python 20 项 + Node 5 项通过，浏览器连接不可用故截图级视觉验收留真实页面复核。
