How is this log built?

From the same records that date every page, so the two can't disagree. A page reads “Published” on the day it went live, “Re-checked” when its facts were read again later, and “Checked” where only the last check is on record. Model and brand pages carry their own dates, listed by brand further down.

Follow it as an Atom feed. Fixes to published errors are listed separately on corrections, and the way each date is set is on how we research.
