County data workflow reference checklist
- Specify the input columns, expected output and handling of missing data.
- Keep the mission limited to the approved public dataset.
- Inspect returned source, tests and execution receipts before reusing the result.
County references are sample public inputs; a page does not represent a completed customer mission or a supported government-system integration.
