A revision ledger helps readers and crawlers understand when a Mars Market address record changed and why the previous wording no longer applies.
Log the material change
Note whether the update involved source provenance, hostname spelling, redirect behavior or a status correction.
Routine style edits should not be represented as a fresh verification event.
Keep dates aligned
Match the visible change note, Article schema and sitemap lastmod date to the actual content revision.
Consistent dates make the record easier for Bing and readers to interpret.
Retain a neutral history
Explain the former status without republishing an unverified destination as current navigation.
Historical context can remain useful without becoming a new actionable claim.
