The changelog for the map. Registry state is verified by pulling every source — the notes below are the registry's own verified strings, dated 2026-11-11.
The registry reached 28 live markets and 9,782 permits: Seattle, Mesa, New Orleans, Norfolk, Baton Rouge, Pittsburgh, San Jose, San Antonio, Philadelphia, Detroit, Nashville, Raleigh, Charlotte, Minneapolis, Columbus, Las Vegas, Washington DC, Fort Worth, Virginia Beach, Maricopa County (AZ), and Memphis joined the original seven (Austin, Los Angeles, Chicago, New York City, San Francisco, Boston, Cincinnati). The trade classifier was rebuilt the same day (primary-signal scoring); the Austin roofing digest went from 26 noisy records to 9 genuine ones.
