Read-only DKIM check for a domain. Without selector, heuristically queries 50 common selectors and explicitly reports that a miss is inconclusive because DKIM has no enumeration protocol. With selector, performs one authoritative exact lookup for a selector obtained from a DKIM-Signature header or mail provider. Returns discovery method, coverage note, parsed key tags, public-key strength, and warnings. Use exact mode whenever the selector is known; use check_email_security for the broader SPF/DKIM/DMARC overview. No auth or destructive actions.
