## Definition
Command Theater指挥剧场是 [[nexus-spatial-discovery]] 中 [[Nexus Spatial]] 产品定义的空间界面布局架构——以用户为中心的弧形"指挥剧场",将工作空间按功能分层布局于不同深度和角度。
## Architecture
```
OVERVIEW CANOPY
(pipeline topology)

## Four Zones
| 区域 | 深度范围 | 内容 | 透明度 |
|------|---------|------|--------|
| **Overview Canopy**(天幕) | 2.54.0m | 管线拓扑 + 健康热力图 | 4070% |
| **Focus Arc**(聚焦弧) | 1.22.0m | 主节点图工作区 | 100% |
| **Utility Rails**(工具轨) | 侧翼 | Agent 库、监控、日志 | 100% |
| **Shelf**(置物架) | 0.81.0m | 运行/停止、撤销、快捷工具 | 100% |
## Three-Layer Depth System
| 层级 | 深度 | 内容 | 透明度 |
|------|------|------|--------|
| Foreground前景 | 0.81.2m | 活跃面板、检测器、模态框 | 100% |
| Midground中景 | 1.22.5m | 节点图、连接线、工作区 | 100% |
| Background背景 | 2.55.0m | 概览地图、环境状态 | 4070% |
## Design Rationale
- **120 度聚焦弧**覆盖人眼自然视野中心区域
- **垂直分层**(天幕→聚焦→置物架)符合"最重要信息在视线中心,次要在下方"的直觉
- **侧翼工具轨**让主工作区保持无遮挡
- **深度层级**允许信息密度分层——背景展示概览,前景展示细节
