Email-authentication posture across a market or an operator's book — SPF and
DMARC adoption and, more importantly, STRICTNESS: how much of the published policy actually rejects
spoofed mail rather than merely monitoring it.
Arguments: market grain ('global', 'europe', or a European TLD) is open; operator-book grain is a
named-provider feature.
Population: the mail-carrying part of the active-domains book — every percentage is of the active domains
that carry mail, not of all websites. A count of policies published in the wrong place is reported
separately as a misconfiguration, never as adoption.
Field definitions and the 'protection theatre' reading: definitions(section='email_security').
