 "why_it_matters": "The flagship quiet failure. `p=none` is *monitor mode* — it publishes a record, generates reports, and instructs receivers to deliver forged mail anyway. It looks like DMARC in every compliance checklist and questionnaire while providing no protection. `malformed` is the same failure by accident.",
