Three jurisdictions with explicit product limits.

The authenticated resolver covers 47,543 current representative facility records. A separate 100-facility research set carries deeper event history for the public evidence demo. Neither dataset represents national coverage.

What passed

NYC states there are no restrictions on Open Data use. Wake County publishes under CC BY 4.0. King County permits reuse and derivatives with a required attribution legend and revocable access.

What stayed out

Los Angeles County and Chicago are not in this demo because the audited pages did not provide reuse terms as clear as the three selected jurisdictions.
