English

Zero out the 56px rail the DSH left sidebar leaves behind when collapsed — while keeping the sidebar one click away. Pure browser-side CSS/DOM patch: no host API calls, no peer dependencies, effective immediately after restart.

The problem

DSH's collapsed-left-sidebar width is hard-coded in @deepseek-ai/dsh-client-ui-layout's AppFrame:

computeColumns(viewport, sidebar, rightbar, collapsedWidth = 56)
// collapsedWidth = darwin || html[data-windows-titlebar] ? 0 : 56

Only macOS (or desktop shells with a custom titlebar) collapse the sidebar to zero. On Windows/Linux the collapsed rail stays 56px wide and empty. This plugin zeroes it and gives the space back to the conversation pane.

Features

• First track only: rewrites only the leading segment of the frame's inline grid-template-columns (!important over inline styles); the right panel's track is untouched. A MutationObserver re-applies after every React re-render (guarded against feedback loops).
• Three-tier expand control — never duplicates an existing one:
  1. dsh-qol installed → uses its always-visible hamburger (.astb-sidebar-toggle); this plugin's own button hides itself. qol is never modified.
  2. No qol → clicks the official sidebar toggle (note its stateful aria-label: "打开侧边栏" when collapsed).
  3. Last resort → a tiny 26px floating "»" button top-left.
• Zero dependencies: requires no host module (sidesteps the 0.2.0 client-modules drift), pure DOM/CSS.
• Touches no DSH source or bundle files.

Install

# via npm registry (recommended):
dsh plugin --profile web add dsh-rail-zero
# or straight from GitHub:
dsh plugin --profile web add github:HelloQingTao/dsh-rail-zero

Restart dsh web to take effect. Uninstall restores everything.

Compatibility

Coexists cleanly with dsh-qol (reuses its hamburger), dsh-better-sidebar and dsh-sidebar-qa.

把 DeepSeek Harness 左侧会话栏收起后那条 56px 空轨道彻底清零，同时保证侧边栏仍然一键可展开。纯浏览器端 CSS/DOM 补丁，零宿主 API 依赖、零 peer 依赖，装上即生效。

解决什么问题

DSH 的左栏收起逻辑写死在 @deepseek-ai/dsh-client-ui-layout 的 AppFrame 里：

computeColumns(viewport, sidebar, rightbar, collapsedWidth = 56)
// collapsedWidth = darwin || html[data-windows-titlebar] ? 0 : 56

只有 macOS（或带自绘标题栏的桌面壳）收起后是完全隐藏；Windows/Linux 浏览器端收起后永远留一条 56px 的空轨道。本插件把这条轨道清成 0，把空间还给对话区。

特性

• 只清第一列：按段改写内联 grid-template-columns 的首段（!important 压过内联样式），右侧面板轨道不受影响；MutationObserver 对抗 React 重渲染（带守卫防循环）。
• 展开按钮三级复用，绝不重复造轮子：
  1. 装了 dsh-qol → 直接用它顶栏那个常驻汉堡（.astb-sidebar-toggle），本插件自己的按钮自动隐藏；
  2. 没有 qol → 点击官方 toggle（注意它收起态的 aria-label 是「打开侧边栏」）；
  3. 都没有 → 左上角浮出一枚 26px 的「»」小按钮兜底。
• 零依赖：不 require 任何宿主模块（避开 0.2.0 的 client-modules 漂移坑），纯 DOM/CSS。
• 不改 DSH 任何源码/ bundle。

安装

dsh plugin --profile web add dsh-rail-zero
# 或 GitHub 直装：
dsh plugin --profile web add github:HelloQingTao/dsh-rail-zero

重启 dsh web 生效。卸载即完全还原。

兼容性

与 dsh-qol 完全共存（复用其汉堡按钮）；与 dsh-better-sidebar、dsh-sidebar-qa 无冲突。
