 ## Alternatives considered
 
+**Keep `input` editable only in the settings document.** The [earlier pi-ai modality decision](../../archived/architecture/2026-08-12-pi-ai-route-default-input-modalities.md) kept this field outside the model-list editor. That leaves users who add custom vision models through the UI unable to enable their image input there. Per-row editing supplies that configuration while the default choice preserves catalog inheritance.
+
 **A two-state switch.** Treating an absent pi-ai declaration as disabled would misrepresent inherited vision support and encourage overwriting catalog defaults. The explicit Default choice preserves the adapter's existing resolution rules.
 
 **Keep image limits when disabling DeepSeek images.** This leaves a configuration that the adapter refuses to save. Clearing the image-specific limits makes the selected text-only state valid while preserving unrelated model fields.

 ## 考虑过的替代方案
 
+**仅允许在设置文档中编辑 `input`。** [早期 pi-ai 输入模态决策](../../archived/architecture/2026-08-12-pi-ai-route-default-input-modalities.md)将该字段留在模型列表编辑器之外。这使通过 UI 添加自定义视觉模型的用户无法在同一界面启用图片输入。逐行编辑提供了该配置，而默认选项保留模型目录继承。
+
 **两态开关。** 将缺省的 pi-ai 声明视为禁用，会错误表达继承的视觉能力，并促使用户覆盖模型目录的默认值。显式「默认」选项保留适配器现有的解析规则。
 
 **禁用 DeepSeek 图片时保留图片限制。** 这会留下适配器拒绝保存的配置。清除图片专属限制，使选择的仅文本状态有效，同时保留无关模型字段。
