Verification Method

Verification levels explain how much support is available: low, medium, high, official, disputed and developing.

Low means preliminary information or a single source; medium means two or more independent sources; high means several sources and at least one primary reference; official means confirmation from a primary official source.

Disputed is used when relevant versions conflict; developing is used when information may materially change.

The method prioritizes primary sources when available, visible links and a clear explanation of what remains to be confirmed.
