  "purpose": "Let a cold reader traverse one bounded assessment claim through its subject, obligation occurrence, evidence, applicability predicate, disposition, and reopening trigger without reconstructing the joins from prose.",
  "boundary": "This model preserves identifiers, relationships, time, authority, limitations, and unresolved work. A complete trace is not proof that a claim is true, evidence is sufficient, a PCI DSS requirement applies, an assessment result is warranted, or a compliance-accepting entity will accept the result.",
  "cold_reader_questions": [
    "What exact proposition is being asserted?",
    "Which stable subject and boundary does it describe?",
    "Which obligation and dated occurrence should produce support?",
    "What period does each evidence object actually represent?",
    "Which explicit predicate is being evaluated?",
    "Which authority may record the bounded disposition?",
    "Where must the conclusion stop today?",
    "What change, contradiction, or missed occurrence reopens it?"
