A record of what changed.
Public data is pinned to a reproducible release. Source updates and observation years remain distinct.
Current publication
Published snapshotThis first source snapshot preserves three missing observations and Canada’s preliminary 2025 population note. A source collection update does not imply every observation was newly released on that date.

Source corrections create immutable observation revisions. Publication promotion selects a coherent data vintage. The operator can activate an earlier valid release during recovery while canonical history remains intact.
No earlier public WDI snapshot is available in this initial build. Future source refreshes retain their source hashes and acquisition manifests privately, and material corrections should receive public notices.
