# findContainmentViolations

[Source](https://github.com/konoe-akitoshi/shumoku/blob/main/libs/@shumoku/core/src/layout/invariants.ts#L110)

Find member nodes whose box is not fully inside their container's bounds (shrunk by \`pad\` on each side). Unknown member ids are ignored — membership resolution is the caller's concern.

```
findContainmentViolations(boxes: readonly BoxSpec[], containers: readonly ContainerSpec[], pad?: number): ContainmentViolation[]
```

## Parameters

| Parameter | Type | Description | Default |
| --- | --- | --- | --- |
| `boxes` | `readonly BoxSpec[]` | No additional description. | `—` |
| `containers` | `readonly ContainerSpec[]` | No additional description. | `—` |
| `pad` | `number` | No additional description. | `0` |

## Returns

```
ContainmentViolation[]
```
