# ComputeNodeGraph.Port.Kind.dependency

Pure “happens-after” edge. No runtime payload, no type lineage, no type compatibility check. The destination is ordered after the source but does not consume its output. Use this to splice a node (e.g. a compute stage) into execution order between two unrelated nodes.

## Declaration

```swift
case dependency
```
