Why this record matters
“September 28” is worth following because a concise public description often conceals a longer documentary argument. Here, September and year provides the most credible route into that argument.
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 Sep 22, 2026. The linked authority identifier is Q2883. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1600, 1066, 1106 and 1213.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. 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.
