  "readme": "Reference parcels for the correctness benchmark at https://urbankitstudio.com/benchmarks. Every row states which source established its canonicalApn. A row whose only source is the endpoint it grades carries selfVerified:true and is excluded from every metric that compares against canonicalApn. There is no owner-name field: this product keeps no owner database, and a committed file of names would be one. Schema and rules are enforced by scripts/validate-ground-truth.mjs.",
  "sampleBias": "Read every number computed from this file as an upper bound on a narrow sample, not as a national figure. Five biases are known. First, county concentration: Cook County, Illinois is 73 of the 146 rows, so a pooled percentage still leans heavily on one county, though it is no longer the only county with scorable rows. Second, parcel type: the first ten Cook rows are downtown Chicago civic and cultural landmarks, which are large, well mapped and single owner, and therefore easier than the residential lookups most callers run. The remaining Cook rows are ordinary parcels spread across sixteen municipalities. The rows added on 2026-08-17 for Denver, Hennepin, King, Travis and Wake are ordinary single family homes on ordinary streets, chosen to pull the sample away from that landmark bias; two Wake rows are shopping centres, kept for property type variety and flagged in their own notes because a large commercial site can be drawn as several polygons under one tax account. Third, resolvability: a row is only admitted when its address maps to exactly one parcel in the independent source, which excludes condo stacks and split parcels, the cases most likely to be answered wrongly. Fourth, verification independence: the county assessor is the only legal origin of a parcel number, so no source is independent of the assessor. What each row is independent of is the SERVING SYSTEM under test: the parcel number was read from the county's own record application or open data service, never from the ArcGIS layer this site queries. That is the circularity that would matter, and it is avoided. Fifth, geography and moment: five metropolitan counties in five states, measured in a single run on one machine, say nothing about rural counties or about any other day. Sixth, sampled-address provenance: the twenty-five rows added 2026-08-22 (Wake, Franklin, Denver, Hennepin, King) use candidate addresses drawn from county-published GIS data - the parcel layer itself for Wake, Franklin and Denver, and county address-point layers for Hennepin and King, whose parcel layers publish no site address - before each address was independently verified against the county's separate tax, auditor or open-data source. An address the layer already knows inflates radius recall relative to a truly blind sample; it does not affect resolution accuracy or the wrong-parcel rate, which measure picking correctly among what was retrieved.",
