Why this exists
DataByCounty is the trust layer behind the portfolio.
CountyScore tells you how a county performs. The vertical sites tell you what to do with a specific domain. DataByCounty answers the harder question: where did each number come from, how fresh is it, what changed it, and where can you inspect the original public source.

Next up: county patch notes.
The first release makes source receipts visible. The next release can snapshot metric changes between data builds, then label whether a county changed because reality moved, a source revised history, or a ByCounty transform improved.
