Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

check_domain | Runs fresh, bounded public SPF, DMARC, MX and optionally specified DKIM-selector DNS checks. Changes the public saved snapshot. Rate limited. DNS findings do not prove message authentication. |
get_saved_resultread-only | Reads the last saved, timestamped public snapshot without making any DNS queries. Results expire after 90 days. |
