Why this record matters
A short description can identify a subject without explaining its stakes. For “Ostyor, Russia”, the useful work is to connect “human settlement in Roslavlsky District, Smolensk Oblast, Russia” to the records capable of establishing context and consequence.
The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Sep 16, 2026. The linked authority identifier is Q4339185. Authority coordinates are 54.016, 32.803. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2002, 1989, 2004 and 1941.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. 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.
