low below — calibrated against hand-rated
truth (single-source .44 · two-source .62 · production-typical .70), so a band
is a measurement, not a promise. High is rare by design: it needs both a
supported assertion and an evidence sentence. A confirmed
or contradicted chip is a Wikidata cross-check;
no chip means Wikidata has no value for that property — the ordinary case
here, and it says nothing either way. A confirm-only
note marks a property whose check can never disagree (Wikidata's border and
capital data is not exhaustive), so silence there is a limit of the check, not of
the claim.

From open datasets, joined by identifier and shown only for properties Wikidata
does not state on this entity — except where the dataset is the registry authority
for the fact (ClinicalTrials.gov on trial registration data): there its value is
shown instead, with Wikidata's noted beside it. Every row carries its dataset
edition and licence.
