When the record changes, the change belongs on the record.

The rebuilt Atlas research library was first published with its current source-linked baseline on July 17, 2026. No material factual, calculation, or methodology correction has been logged since that publication.

A material correction will list the date, affected URL, original issue, corrected statement or value, and the source used to resolve it. Routine spelling, style, and layout changes do not receive a new substantive update date.
