The prediction and assertions are the 7 claims: statements the public record can support or contradict. 2 are resolved, 2 are not yet assessed, and 3 name no date, number or outcome precise enough to check. Everything else (opinions, insights, what ifs, disclosures) can never be settled by the record, so it carries no assessment.
