high ≥ 0.90 · emerging ≥ 0.65 · 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.

evidence “The researchers described a particle interaction documented at the Sanford Underground Research Facility — built in a former gold mine in the state's Black Hills region — that may have involved a hypothesized particle called a WIMP, short for "weakly interacting massive particle." This is one of the proposed candidates for being a dark matter particle.” yahoo.com · read source
