## Definition

语义缩放（Semantic Zoom）——4 级导航范式，随用户缩放层级揭示不同粒度的信息，类似 iPad/iOS 地图的缩放交互但应用于工作流导航。

由 [[nexus-spatial-discovery]] 中 [[XR-Interface-Architect]] 定义。

## Four Levels

| Level | What You See | Use Case |
|-------|-------------|---------|
| Fleet View | All workflows as abstract shapes, color-coded by status | Overview, portfolio management |
| Workflow View | Node graph with labels and connections | Building, editing workflows |
| Node View | Expanded configuration, recent I/O, status metrics | Inspection, configuration |
| Trace View | Full execution trace with data inspection | Debugging, root cause analysis |

## Design Principles

1. **Glanceable Before Inspectable**：关键信息在 2 秒内通过颜色/大小/运动/位置感知
2. **Progressive Spatial Complexity**：新用户从接近 2D 开始，空间能力随信心增长逐步揭示
3. **Smooth transitions**：Overview → Focus 600ms，Focus → Detail 500ms，最大 600ms

## Relation to Command Theater

- Fleet View 对应 Overview Canopy（大范围，高空俯瞰）
- Workflow/Node View 对应 Focus Arc（主要工作区）
- Trace View 对应 Utility Rails（详细日志/追踪面板）
