1 not yet assessed 1 not checkable as stated how the 2 claims stand · each chip opens the sources

1 prediction · 1 assertion · 1 disclosure · every statement was checked. The prediction and assertion are the 2 claims: statements the public record can support or contradict. 0 are resolved, 1 is not yet assessed, and 1 names 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.

The record, in short
