  "statement": "The customer-profile and A2P bundle identifiers must be distinct, belong to the same account, and not be swapped.",
  "rationale": "The two identifiers have the same prefix and the same length, sit next to each other in the request, and describe different objects — so transposing them produces a submission that validates structurally and fails on a message about bundle validation. It is one of the very few brand errors that is genuinely a typo rather than a misunderstanding.",
