## Definition

命令剧院（Command Theater）——以用户为中心的空间界面布局范式，以弧形剧场形式围绕用户组织内容。源自 [[nexus-spatial-discovery]] 中 [[XR-Interface-Architect]] 的设计。

## Architecture

```
                        OVERVIEW CANOPY
                     (pipeline topology)
                    ~~~~~~~~~~~~~~~~~~~~~~~~
                   /                        \
                  /     FOCUS ARC (120 deg)   \
                 /    primary node graph work   \
                /________________________________\
               |                                  |
    LEFT       |        USER POSITION             |       RIGHT
    UTILITY    |        (origin 0,0,0)            |       UTILITY
    RAIL       |                                  |       RAIL
               |__________________________________|
                \                                /
                 \      SHELF (below sightline) /
                  \   agent status, quick tools/
                   \_________________________ /
```

## Four Zones

| Zone | Position | Content |
|------|----------|---------|
| Focus Arc | 120°, 1.2-2.0m | Primary node graph workspace |
| Overview Canopy | above, 2.5-4.0m | Miniature pipeline topology + health heatmap |
| Utility Rails | left/right flanks | Agent library, monitoring, logs |
| Shelf | below sightline, 0.8-1.0m | Run/stop, undo/redo, quick tools |

## Three-Layer Depth System

| Layer | Depth | Content | Opacity |
|-------|-------|---------|---------|
| Foreground | 0.8-1.2m | Active panels, inspectors, modals | 100% |
| Midground | 1.2-2.5m | Node graph, connections, workspace | 100% |
| Background | 2.5-5.0m | Overview map, ambient status | 40-70% |

## Design Rationale

- 用户处于中心，信息按重要性和使用频率分层
- z-axis（深度）对应执行顺序：input nodes 最远，output nodes 最近
- 减少晕动症：所有交互发生在 0.8-2.5m 范围
- 与 [[Semantic-Zoom]] 配合实现渐进式空间复杂度
