Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jun 20, 2026. The linked authority identifier is Q4553170. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1777.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it.

Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
