  "rationale": "This is the one element every provider screens for mechanically, because it is the consumer's exit and the thing a complaint is measured against. Terms drafted as a legal document rather than as instructions often describe the right to withdraw consent without naming the keyword, which reads as compliant to the author and fails the string match.",

  "notes": "The catalog exempts single-message programmes and lets T-Mobile accept the opt-out in the advertisement instead of the terms for print CTAs. Neither exemption is expressible as a tag we hold, and both are narrower than the registrations this registry is aimed at, so the rule fires universally.",
