Returns the variable dictionary shipped with the selected Penn World Table release - one entry per column with name, description (from the release Legend sheet), and type grouping. Includes a short methodology note summarising the expenditure- vs output-side real GDP distinction, the perpetual-inventory capital stock construction, TFP levels, and the human capital index. Use before querying other endpoints to confirm variable names and decode column meanings without reading the upstream user guide.
