 "evidenceNote": "Each dossier separates three claims: drone presence, impact and attribution, each with its own evidence state and supporting sources. 'reported' means a source describes the claim without sufficient identification evidence; claims by parties to a conflict are never 'confirmed' on their own. Counts reflect dossiers in this curated archive, not all incidents worldwide. windowStart/windowEnd are reporting-window calendar bounds, not individual event days; legacy date remains the compatibility/sorting date for such records.",
 "locationNote": "lat/lon are the dossier's own approximate coordinates (see locationPrecision) and are empty when the incident location is unknown. referencePoint {lat, lon, level, name} is a display reference only: a fixed point in the named city (GeoNames), region (its administrative seat), sea or country (Natural Earth label point), derived at build time. It is not a geolocation, not an estimate of the incident location and may change when the dossier's place becomes more precise: reference point; incident location unknown.",
 "detailsNote": "media, followUp and archiveEntity are editorial, source-indexed additions. operationalEffects may also contain AI-assisted source-checked additions identified by autoEnrichments, with the dossier remaining review=auto. autoEnrichments preserves the literal quote, speaker, source publication cutoff and check provenance; a quote match is not editorial review or independent confirmation. Media is publisher-link only, has its own evidence status and never establishes drone presence or attribution. Debunked original-media links are removed; archived revisions omit media references. archivePattern is computed from mapped published event records at generated time, not a worldwide incident count. Null asOf means not established; publication time is not substituted.",
