What it reads
The CAA records in your DNS. An issue tag passes. No records warn, and so do records with only a reporting contact, or only issuewild, which covers wildcard certificates alone.

What the check does, and where it stops.
Why it matters
Without CAA, any certificate authority in the world can issue a certificate in your name.
What a failure looks like
A failure is a finding in your result. The check is scored, so it can lower your score, and the Full Report gives every finding its severity and a fix. If the check cannot finish, it is recorded as unknown: it carries no penalty, and it is never a pass.
Where its limits are
None.
