Which sources we accept, in what order of authority, and what happens when two of them disagree.
We do not cite aggregator blogs, resellers or social posts as evidence for any published value. Where a copycat site mimics a free official service, the country record says so.
Every record has a next review date: quarterly for verified records, within 30 days for reviewed ones. Policy-monitor entries (the change log) are checked weekly, and the checker warns the moment a record ages past its review window.
When sources conflict, the record takes the highest authority and records the conflict in the source ledger. If the conflict cannot be resolved from official text, the record drops to verification required and displays the warning on every surface, including the checker.
Each value links to the owning authority, with jurisdiction, checked date and reviewer shown in the record's ledger block. Snapshots of cited pages are retained internally for audit.
