 - **自动调整内部统一使用模型单位**：`ObjectPassageProjectionOptimizationResult.ComputedLiftOffsetMeters` 改为 `ComputedLiftOffsetModelUnits`，移除中间 `ConvertToMeters`/`ConvertFromMeters` 的反复转换，只在 UI 边界（`EditRotationWindow.OnAutoAdjustClick`）做一次转换。
 
-- **调整物体窗口等待光标**：`OnAutoAdjustClick` 添加 `try/finally` 包裹，执行时设置 `Cursors.Wait`，参照项目现有模式。
+- **删除动画控制视图无用控件**：移除 `AnimationControlView.xaml` 中无绑定的"选择模型物体" RadioButton。
+
+- **碰撞检测报告截图 + 按钮始终可见**：`CollisionReportDialog.xaml` 缩略图区域的 `Visibility` 绑定从外层 `Border` 移到内层 `ItemsControl`（缩略图），`+` 按钮始终可见。
+
+- **Rail 路径重选起点时清除安装辅助线**：`ExecuteSelectAssemblyStartPointAsync` 和 `ExecuteRepositionRailStartPointAsync` 进入起点选择前调用 `ClearAssemblyInstallationReferenceVisuals()` 隐藏安装点辅助线。
+
+- **数据库初始化设置版本号**：`PathDatabase.InitializeDatabase()` 创建表后执行 `PRAGMA user_version = 10000`，使"修复数据库"正确显示版本信息。
