WHY IT IS DIFFERENT

It correlates DNS intent with header truth.

Most checkers inspect one record. This studio compares pasted DNS records with Authentication-Results, return-path alignment, DKIM d= domains, DMARC policy, ARC clues, BIMI readiness and bulk-sender evidence, then produces a support-ready artifact instead of a vague score.
