### Path parameters

<ParamField path="id" type="string (uuid)" required>
  Sandbox identifier
</ParamField>

### Query parameters

<ParamField query="path" type="string">
  Directory to watch (default /workspace)
</ParamField>

### Response

Returns `text/event-stream` — Server-sent event stream. Opens with one `snapshot` event whose data is `&#123;files: string[], path&#125;` (an `ls -R` listing of the watched directory), then a `change` event with `&#123;added: string[], removed: string[]&#125;` whenever the listing differs on the 5-second poll, with `: heartbeat` comments every 15s.
