# Type Alias: UncheckedRef

```ts
type UncheckedRef = string & {
  [unchecked]: true;
};
```

Defined in: [registry.ts:176](https://github.com/simshanith/lit-ui-router/blob/6e47ef8d8a4b24e99c074fb5c8c9cfaddfdb36a4/packages/ui-router-registry/src/registry.ts#L176)

An explicit opt-out for a target the registry can't see, such as a name
built at runtime or a state registered at runtime: `name as UncheckedRef`.
Its params are loose. Nothing is unsafe at runtime; the target is just
unverified.
