The underlying report pressure-tested its own claims and sorted them into three tiers. This page shows all three — including the ones it concluded were unsupported.
The editorial standard in the source report puts it plainly: a documented finding placed next to an unsupported claim means a journalist dismisses the entire document. That is not caution for its own sake — it is the practical reason most political material never gets used by anyone who could act on it.
So the third tab is not an afterthought. Publishing the claims that failed, by name, next to the ones that held is the only thing that makes the first tab worth reading.
