Validation Status	⚠️ Bogus — the parent still publishes a DS record, but the delegated nameservers don't answer, so no signed answer can be fetched. The zone isn't serving broken signatures; it isn't serving at all.
AD Flag (resolver validates)	✗ Not set
DS Record	✓ Found
DNSKEY Record	✗ Not found
Flags	resolution failed: failure

🏷️ SOA#
