What the centroid can support
The latitude and longitude represent a postal centroid from the source snapshot. They are useful for approximate map previews, nearby-record review, deduplication checks, and distance-based QA.
They should not be treated as an official delivery boundary, address-level geocode, tax boundary, or service-area guarantee.
