LIVE ENDPOINT METADATA

Email authentication posture check: parses SPF, DMARC and DKIM plus MX for any domain and grades deliverability/anti-spoofing gaps (SPF +all, SPF >10 lookups, DMARC p=none, missing DKIM). Clean JSON for deliverability and security-ops automation.

METADATA PROVENANCE

Source catalog records are retained separately from live endpoint observations. Sonar score, uptime, and latency are advisory metrics. CDP indexing is not inferred from validation.
