+# 应用接入页面设计验收
+
+- 源视觉依据：`/var/folders/hn/vg5lxj0j60d2cp0k6vv_k0mw0000gn/T/codex-clipboard-70a7e9c2-c058-4665-b236-e73ccef6d2b0.png`
+- 浏览器实现截图：`development_records/ui-evidence/sso-integration-2026-08-03/implementation.png`
+- 同屏对比图：`development_records/ui-evidence/sso-integration-2026-08-03/comparison.png`
+- 验收地址：`http://localhost:5174/`
+- 状态：管理员已登录，进入“应用接入”，打开“新增接入应用”弹窗
+- 视口：1380 × 900 CSS px，设备像素密度 1
+- 源图像素：1380 × 1026；实现图像素：1380 × 900
+- 归一化方式：保持两张图 1380 px 等宽，不缩放；对比图仅将实现图底部补白至 1026 px，避免密度或缩放造成误判
+
+## 全视图对比证据
+
+- 原界面将基础字段、回跳地址、自动注册和启用开关连续堆叠，字段说明与控件边界不清，底部留白失衡。
+- 新界面拆分为“基本信息”“登录后回跳”“访问与账号策略”三个语义区，主次关系、上下间距与操作路径清晰。
+- 应用列表合并重复维度并限制列宽；在容器宽度不足时切换为卡片布局，不再依赖横向滚动。
+
+## 聚焦区域对比证据
+
+- 表单区：输入框高度、标签间距、两列表单对齐、文本域高度均保持一致；说明文字从占位符中分离，阅读层级更稳定。
+- 策略区：“启用应用”和“自动注册新学员”采用同一行式设置组件，开关右对齐；自动注册开启后才展示默认权益，减少无关内容。
+- 标签页：在 1380 px 视口下，页面、标签内容和表格的 `scrollWidth` 均等于 `clientWidth`；无页面级横向滚动。
+
+## 发现项
+
+- 未发现仍需处理的 P0、P1 或 P2 问题。
+- P3：后台整体框架在小于约 1180 px 的窗口仍有全局最小宽度限制；该行为不是本次应用接入页面引入，且不影响当前桌面端验收范围。
+
+## 交互与运行验证
+
+- 已验证进入应用接入、切换“接入应用 / 账号绑定 / 登录审计”、打开与关闭新增应用弹窗；自动注册开关可正常显示和隐藏默认权益配置。
+- 已验证 1380 × 900 与 1280 × 720 桌面视口；弹窗内容过高时仅弹窗正文区域滚动，头部和底部操作保持可见。
+- 已检查浏览器控制台，新增错误和警告为 0。
+- 已执行前端类型检查与生产构建，构建通过。
+
+## 对比历史
+
+1. 初始问题：弹窗内容拥挤、策略控件分散；应用列表固定列宽总和过大，引发横向滚动。
+2. 修复：分区重构弹窗；合并列表信息列；补充容器宽度约束和窄容器卡片布局。
+3. 复验：同屏对比中信息层级与留白已改善；桌面视口下页面级横向滚动已消除。
