The claims ledger.

When a party to the war states a fact that evidence can later settle, such as a target hit, losses inflicted on the other side or a denial of responsibility, it goes in this ledger. Each claim is checked against the record at 7 days, 30 days and then quarterly, and given a verdict. Over time each party's track record shows how often its word held up, with the count it rests on. Positions, threats and intentions are recorded as statements and not scored. A claim still open after 12 months becomes unresolvable.
