## What each position does



- The catalog selector model does not reach the output jack on every drawn throw (selectionReachesTip); position labels follow the source sheet, not a verified simulation table.
- The transcribed super-switch map produces a short in the passive model (noShort); lug wiring matches the manufacturer diagram.
- Some switch terminals read as unwired in the catalog contact table (requiredTerminalsWired) despite matching the drawn lug map.
