Signed but not delegated securely

The zone is signed but the parent has no DS record, so the signatures are not used. Publish the DS record at your registrar.

NSEC3 with extra iterations or salt

NSEC3 uses 7 iterations and a 8-byte salt. RFC 9276 recommends 0 iterations and no salt: extra iterations cost resolvers CPU and add no real protection, and some validators treat high counts as insecure.
