```
selection.decodeWhereDocument(input: : unknown) -> WhereDocumentV1
```

Validate a WHERE document and restore camelCase criteria names.

The returned document is canonical and deeply frozen.

## Raises

- `QueryValidationError` — when the document or its criteria are invalid.

## Example

```ts
import { decodeWhereDocument } from "libtmux/selection";
const document = decodeWhereDocument(
  JSON.parse('{"model":"pane","version":1,"where":{"pane_title":"logs"}}'),
);
if (document.model === "pane") snapshot.panes.where(document.where);
```
