  "title": "Number pooling must be declared consistently with the campaign scale",
  "statement": "The number-pool attribute must reflect whether the campaign will actually send from multiple numbers.",
  "rationale": "Number pooling is a filtering signal: sending similar content across many numbers without declaring a pool is the definition of snowshoeing, which carries a four-figure pass-through fee. Declaring a pool you do not use is harmless by comparison, so the asymmetry favours declaring.",
