"summary": "A cyber questionnaire records what a company says its policy is. Claims investigation records what actually happened. The gap between them is where coverage disputes live.",
"lede": "An underwriter asks whether dual authorisation is enforced on wires above a threshold. The answer is yes, and it is true of the policy. Whether it was true of the wire that generated the claim is a different question, answered eighteen months later by lawyers.",
