-**只要 PR 涉及可见 UI 改动、UI 交互改动，或以 UI 测试作为主要验收依据，就必须在 PR 中提供截图证据。**
+**只有 PR 导致用户可见的 UI 样式、布局、组件外观、文案呈现或可见状态发生变化时，才要求提供截图。**
 
-最低要求：
+例如以下情况需要截图：
+
+- 页面、弹窗、卡片、按钮、表格等外观或布局发生变化；
+- 新增可见组件、页面或状态；
+- loading / success / error / empty 等可见状态样式发生变化；
+- 字体、颜色、间距、图标、格式化显示等视觉结果发生变化。
+
+以下情况**不要求截图**，只需在 PR 中注明“无可见 UI 变化”：
+
+- 纯交互逻辑调整，但最终视觉表现不变；
+- URL / 输入校验、安全策略、权限判断等 UI 层逻辑修复；
+- 数据绑定、状态机、事件处理、后台 IPC、缓存、持久化等内部行为变化；
+- 仅增加或修改 UI 单元测试，但没有改变实际视觉结果；
+- 纯内部重构。
+
+需要截图时，最低要求：
 
 - 至少提供一张 **修改后的 UI 截图**；
 - 如果是在修改已有界面，优先提供 **Before / After 对比截图**；
 - 如果是新增页面、弹窗、状态或组件，没有 Before 场景时，只提供 After 截图即可；
-- 如果 PR 修改了多个关键状态（例如 loading / success / error / empty），应覆盖最关键的状态截图；
-- 纯内部重构且确认没有任何视觉变化，可以在 PR 中注明“无 UI 变化”，无需截图。
+- 如果 PR 修改了多个关键可见状态，应覆盖最关键的状态截图。
