Validate DMARC Record

validate_dmarc_record
Read-onlyIdempotent

Use this when the user pastes a DMARC record and asks whether it is valid, correct or safe. Validate a pasted DMARC record: parsed tags, level'd findings, and whether it is valid. No DNS lookup — pass the record string itself. upgrade_record previews a stronger policy and is capped at p=quarantine: a pasted record carries no alignment evidence, and p=reject is unlocked only by aggregate-report evidence over a full reporting window (monitoring), never by a scan. Present any returned record verbatim.
