Canonical source versions, checksums, coordinate-quality boundaries, and data-product details are recorded in `.github/domains/fate-analysis/data-products/locations/sources.lock.json`, `manifest.json`, and `README.md` in the FateCat source repository. Coordinates are WGS84 administrative-area or city center points, not exact birth-location coordinates.
