Certificate renewal patterns can reveal infrastructure continuity, but automated issuance means they must never be treated as identity proof.
Build a dated issuance timeline
Record certificate start and end dates for the exact hostname under review.
A timeline is more useful than one current certificate because it shows gaps and changes.
Account for automated renewal
Short certificate lifetimes and frequent renewals are normal on modern hosting platforms.
Regular issuance indicates technical continuity, not who controls the service.
Notice scope changes
A certificate may add or remove hostnames, switch between wildcard and exact names or move to another issuer.
Material scope changes should trigger a new Mars Market address review.
Compare renewal with DNS history
A renewal near a nameserver or hosting change can provide useful chronology.
The signals should be recorded together while keeping ownership conclusions separate.
State the narrow finding
Report that certificate activity is consistent or inconsistent with a claimed timeline.
Do not translate that technical observation into an official or safe label without stronger evidence.
