 "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.",

  "locationPrecision": "region",
  "summary": "Reported drone sightings led to a flight suspension at Hannover Airport on 26 December 2025, with disruption continuing into the following day.",
  "impact": "The airport operator reports seven diversions and two next-morning cancellations. NDR gives a start shortly before 21:00 and about 3.5 hours; dpa gives 21:47–00:16. The dpa page lead says over four hours, inconsistent with its own detailed times. Exact closure times and duration remain unresolved.",
  "evidence": "The airport operator is the original operational source quoted by NDR and dpa. NDR separately quotes police confirming reported sightings; this provides a second institutional origin, not a recovered-device identification. Repetition of the airport statement by different newsrooms is not independent drone corroboration.",
  "unknown": "No operator or motive established. The sources disagree on closure timing; no precise duration is selected. Details about individual medical staff or patients are omitted. No drone location or flight path is supplied.",
  "attribution": "No operator or responsible organisation established by these sources; no criminal charge or conviction is asserted.",
