The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 25, 2025. The linked authority identifier is Q2704721. Authority coordinates are 0.000, 13.000. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.

The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
