 "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, operationalEffects, followUp and archiveEntity are editorial, source-indexed additions. 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.",

  "summary": "A suspected-drone alarm interrupted flights at Gothenburg Landvetter Airport on 6 November 2025. The investigation was later closed because there was insufficient evidence establishing drone presence.",
  "impact": "Swedavia announced reopening around 21:30 local time after an alarm shortly before 18:00. Flights diverted and departures were postponed or cancelled. Three next-morning cancellations were an interim airport count just after 06:00, not a final incident total.",
  "evidence": "Swedavia independently confirms operational disruption through SVT; police investigated witness reports. SVT reports uncertainty, and Härryda-Posten relays GP on the later closure and lack of secure observations or technical evidence. Inconclusive does not establish a particular star, aircraft or hoax.",
  "unknown": "Exact closure boundaries, final affected-flight totals, object identity and operator remain unknown. The original SVT timestamp precedes late-added reopening and next-morning updates. The point represents Landvetter locality rather than airport or object coordinates.",
  "attribution": "No operator or responsible organisation established by these sources; no criminal charge or conviction is asserted.",
