Walk the graph and ensure every link endpoint references an existing \`NodePort\`. Idempotent — graphs that already comply pass through unchanged (modulo deep-copy).

```
ensurePorts(graph: NetworkGraph): NetworkGraph
```

## Parameters

| Parameter | Type | Description | Default |
| --- | --- | --- | --- |
| `graph` | `NetworkGraph` | No additional description. | `—` |

## Returns

```
NetworkGraph
```
