  "statement": "No message may be sent to a number after a valid opt-out is received, whatever the campaign type.",
  "rationale": "This is the obligation every other opt-out rule exists to make achievable, and the way it is breached is almost never a decision: a send was already queued, a scheduled blast was built from a list exported yesterday, or the suppression check happens at list-build time rather than at send time. Political programmes get their own line in the carrier rules because operators assume the exemptions that cover consent also cover revocation. They do not.",

    "A CSV exported for a blast is a snapshot of consent at export time; every opt-out between export and send is invisible to it unless the platform re-checks."

  "notes": "Absorbs OPS-069 and MSG-268, which restate it for political programmes where the carriers call it out specifically. Undecidable before traffic. What the user has to verify is where in their send pipeline the suppression check sits — build time is the common answer and it is the wrong one.",
