 A card stages what the user types and writes it only when they save. Each control renders staged text, so what is on screen is exactly what a save would store; **Discard** drops the drafts, and a card holding unsaved edits says so on its header even while collapsed. A successful save collapses the card after the read-back confirms the writes; a failed save keeps the card open, reports the failure, and retains the drafts for correction. A reset stages the composed default rather than writing immediately, and a draft the field does not accept blocks the save instead of being dropped. The Host is the only authority on whether a value was accepted.
 
-The **Subagent** card groups delegation limits and model selection under one disclosure and one save/discard footer. **Maximum recursion depth** and **Subagent count limit** appear side by side, stacking on narrow screens. Information buttons reveal a two-row depth example and the shared count rule; validation errors remain visible below the input. Depth retains explicit tool overrides. Capacity counts live continuable descendants across all recursion levels, including waiting children and excluding the root, one-shot runs, and external providers. Saving applies to later delegation attempts; lowering capacity does not stop existing children.

Saving applies to later delegation attempts; lowering capacity does not stop existing children.
 
 The model selection section stages its permission switch and exact model checkboxes together. Enabling requires at least one selected adapter route. Saving submits `enabled` and `allowedModels` in one mutation fenced by the revision where that draft began; a newer Host revision marks the draft failed instead of restoring a revoked route. Disabling retains the selected routes for later reuse. Available models are grouped by provider, while saved routes absent from the current catalog appear last and remain removable. Adapter names and model descriptions remain live directory metadata and are not stored, and the card refreshes them after adapter changes, settings commits, and reconnects.

 模型选择分区会同时暂存其权限开关与精确模型复选框。启用时必须至少选择一条适配器路由。保存会在一次 mutation 中提交 `enabled` 与 `allowedModels`，并以草稿开始时的 revision 设栅；Host revision 更新后，草稿会标记为失败，而不会恢复已撤销的路由。关闭时会保留已选路由供以后重新使用。可用模型按提供方分组；当前目录中缺失的已存路由排在末尾，且仍可移除。适配器名称与模型描述仍属于实时目录元数据，不会存储；适配器变化、设置提交和重连后，卡片会刷新这些元数据。
