An address repeated by many pages may still originate from one unsupported post. Provenance asks where a claim began and how it was carried forward.
Find the earliest attributable source
Start with the oldest source that clearly identifies who published the Mars Market address claim. Copies that omit authorship or dates add volume, not independent confirmation.
When the original source cannot be identified, label the address as unverified and avoid treating downstream repetition as evidence.
Distinguish ownership from commentary
A commentator can describe a claim without controlling the service or domain. Look for evidence that connects the publisher, the domain and the stated update process.
Brand names, logos and familiar wording are easy to reproduce and do not establish authority on their own.
Follow the claim through later updates
A reliable source should correct or retire outdated information visibly. Compare later notices with the original claim and note whether the destination, status or verification method changed.
Silent edits reduce traceability because readers cannot tell what was previously asserted.
Require independent corroboration
Two pages copying the same sentence are not two sources. Independent corroboration should come from separately maintained records with their own dates and evidence.
Agreement is useful only when the sources are not simply echoing one another.
Document uncertainty honestly
If provenance is incomplete, record the missing link in the evidence chain. A transparent “verification pending” label is more useful than an unsupported official claim.
Clear uncertainty protects users and gives future reviewers a precise question to resolve.
