Begin with the source’s own compact description: “Contrahierbas” is mountain in Peru. The dossier treats that line as a proposition to test through Contrahierbas, mountain and Peru, not as a finished interpretation.
Why this record matters
The phrase “mountain in Peru” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Aug 11, 2026. The linked authority identifier is Q3689097. Authority coordinates are -9.106, -77.490. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
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.
How to read it
