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。

Model selection plugin, browser half: TWO entries over ONE per-session directory owned by ModelService (ctx.models). For ordinary sessions, the /model popupSelect contribution (registered through ctx.command) and the composer's named conversation.input.model seat both load the session's advisory directory through session.models and submit through session.selectModel via the same ModelDirectory instance. The compact composer trigger opens a two-level Model/Effort menu: models stay provider-grouped, while the selected exact model supplies its adapter-owned effort names, descriptions, and default. The Host-reported provider/model/reasoning target is the single fact both entries echo; /model applies the selected model's default effort, and the composer can then choose any advertised effort. Directory loads and selections share a generation counter so an older response never overwrites a newer one; a connection reset drops every resident projection and repulls the Host-restored target before display. Provider-local metadata failures list inline while usable groups stay selectable, and selection failures retain the prior target and directory. Directories are per-session, resolved lazily through ctx.models.directoryFor(sessionId), and disposed with the session scope. Addressed subagent sessions expose neither entry, and their directory rejects loads, selections, and reconnect refreshes, because ordinary Agent-bound model RPCs would activate persisted child history outside the direct-parent continuation seam.
The /client export surface is the plugin body (apply/inject), ModelService, ModelDirectory with its state shape, and the seat's injected face type.
Model Experience
Indirectly, through the session.selectModel RPC available to ordinary sessions, both entries submit the provider/model/reasoning target that the Host snapshots at the next prompt-assembly boundary, so the following request uses the chosen route and effort while a running step keeps its assembled target; the selection becomes durable only when the existing request header records a request that consumes it, and menu interaction adds no prompt content.
KV Cache effect
Switching the route can reduce or invalidate provider-side cache reuse for subsequent requests; the prompt prefix itself is untouched.
Known Limitations and Deferred Work
- No create-time or addressed-subagent selection — both entries require an existing ordinary session's Agent; there is no draft-phase model choice to fold into session creation, and subagent continuation deliberately exposes no independent model-retargeting contract.
- Directory names are presentation-only — selection and persistence use provider/model/effort ids; a provider whose catalog or exact-model metadata lookup fails lists as an unselectable failure row until reload.
- No arbitrary effort input — the composer offers only the exact model's adapter-advertised levels; an adapter without reasoning metadata leaves the Effort row absent.
