1. 统一会话列宽度轴：新增 --dsh-chat-content-width（748px），输入框、todo、goal、queue、approval、plan review、ask question 等容器的宽度与边距全部由该变量推导，消除各面板之间的像素漂移，窄视口下的边缘留白也保持一致。 2. 输入框自适应与细节：控制行改为容器查询（460px 阈值以下权限选择器只显示图标+下拉，隐藏文字）；卡片圆角 20→22、行内边距调整并整体下移 2px（发送按钮除外）；permission/model 触发器统一 24px 圆角；Plan 与 Read Only 间距 +8。 3. 修复浮层菜单溢出：slash 菜单与命令弹层钳制到输入卡片宽度，超长行以省略号截断；Tooltip 增加 12px 视口边缘安全距离。 4. 增加与替换图标：Add provider 改用输入框同款加号图标（IconPlusOutline16），统一图标尺寸与字号。 5. 统一 Settings → Models 组件：补齐按钮 hover 态、select 下拉箭头不再贴边、标题区与 provider 卡片间距 +12。 6. 侧边栏交互：add workspace / group by / create session / 收起侧边栏四个图标按钮增加 500ms 延迟 tooltip（前两个向下弹出）；展开态的 New Session 不再重复显示 tooltip；侧边栏窄屏自适应收起逻辑微调。 7. 其他：hero 区 workspace 徽章右移对齐；附带 Agent Note（中英双语）记录共享宽度轴与容器查询的设计取舍。

Shell plugin: three-column AppFrame (drag handles and concession chain) plus the ctx.layout panel-geometry service; it registers into the runtime-owned root slot and declares sidebar, conversation, details, and conversation.empty. The sidebar resize boundary is an invisible hit strip, while the details boundary retains its floating pill; only details shrinks during concession and then auto-closes. A closed sidebar retains a 56px control rail while details closes to zero width. The package also seats the theme presenter: it consumes resolved ctx.theme snapshots and projects them onto the document (html { color-scheme } for native UA chrome, body[data-ds-dark-theme] from the active color scheme, plus the theme's alias tokens as inline variables on body).
AppFrame always mounts the conversation and details columns; a connected Session renders through SessionProvider. The transient layout store starts the sidebar at its default width and details closed, and it never reads or writes localStorage. Hero and other unselected states also derive a zero rendered details width without changing that stored preference. AppFrame retains the last non-blank Session id across those states: the first Session remains closed, an explicit details action opens the contract default width, returning to the same Session restores its unchanged width, and selecting a different Session closes details before paint. The conversation owner share is empty, while the sidebar owner share contains only collapsed and width; registrants obtain business data from standard hooks and actions from their own inject faces.
The /client export surface is the plugin body (apply/inject), LayoutService, and the four owner-share interfaces. AppFrame, the panel store, and the concession solver remain package-internal; tests import internals through /src.
Model Experience
None, as the layout shell manages browser viewing state; nothing here reaches a model request.
KV Cache effect
None; this package neither assembles nor sends a provider request.
Known Limitations and Deferred Work
- Panel geometry is transient — reload restores the sidebar default and details closed; switching between distinct Session ids also closes details and forgets its dragged width, while unselected surfaces render details at zero width without modifying geometry.
- Concession-chain auto-close derives a zero width without touching the preferred width — the panel restores itself when the window widens; consumers must not read the stored details width as the rendered truth.
- Scroll anchoring during squeeze reflow is not implemented — deferred with the virtualized-list project.
