-Model selection plugin, browser half: TWO entries over ONE per-session directory owned by `ModelDirectoryResolver` (`ctx.modelDirectories`). For ordinary sessions, the `/model` popupSelect contribution (registered through `ctx.commandUi`) 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. `/model` applies the selected model's default effort, and the composer can then choose any advertised effort.
+Model selection plugin, browser half: TWO entries over ONE per-session directory owned by `ModelDirectoryResolver` (`ctx.modelDirectories`). For ordinary sessions, the `/model` popupSelect contribution (registered through `ctx.commandUi`) 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 and default. The menu renders model and effort names only; catalog descriptions remain available to other consumers. `/model` applies the selected model's default effort, and the composer can then choose any advertised effort.
 
 The Host-reported provider/model/reasoning `ModelSelection` is the single selection fact, but it is echoed only when the exact provider/model pair remains in the advertised groups; an absent catalog row leaves the routable selection intact while the trigger prompts `Select model`, no stale row is synthesized, and no Effort row is shown until the user picks an advertised model. 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 selection before display. Provider-local metadata failures list inline while usable groups stay selectable, and selection failures retain the prior selection and directory.

 Host 报告的 `ModelSelection` 是唯一的选择事实，其中包含提供方、模型与推理（reasoning）强度；但只有当该提供方／模型对仍在已公布分组中时才会回显。目录行缺席时，可路由的选择保持不变，但触发器会提示 `Select model`；系统不会合成陈旧行，且在用户选择已公布的模型之前不会显示 Effort 行。目录加载与选择共享一个代次计数器，旧响应不会覆盖新结果；连接重置会丢弃所有常驻目录投影，并在显示前重新拉取 Host 恢复的选择。各提供方的元数据获取失败会内联列出，同时可用分组仍可选择；选择失败会保留先前的选择和目录。
