World Countries (Natural Earth Admin-0)
Natural Earth 1:10m Admin-0 Countries v5.1.1 (release 2022-05), 258 features. Key column ISO_A3_EH (resolves the -99 disputed/dependency cases in raw ISO_A3 for France/Norway/Brazil/Kazakhstan/Australia territories; 14 genuine no-ISO3 micro-entities remain -99, e.g. Somaliland, Kosovo, N. Cyprus). Public domain, no attribution required per naturalearthdata.com/about/terms-of-use. Fetched from the official naciscdn.org CDN mirror. Fixes applied at produce: 1 geometry repair, multi-normalisation; 7 features cross the antimeridian and render split until antimeridian splitting is supported (Russia, Fiji, Kiribati, NZ, US Aleutians, Antarctica claims) — known display limitation, not a data defect. Nightly miss-resolver bucket admin:global:country:: join-tested against both acceptance files (OWID share-of-population-by-religion CSV): match_rate 0.9065 (194/214), 20 unmatched are OWID's non-country aggregate codes (continents/income groups/World), not real countries. join_test's `joined` flag nonetheless returned false both times citing a time-series period-selection requirement whose diagnosis text did not change even after supplying the period_selection parameter it requested (which is not in the tool's declared schema) — flagged as a possible tool anomaly for human review; recording published_unverified rather than resolved.
