 "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": "Helsinki Airport traffic was suspended on 15 May 2026 after a precautionary drone warning. At a later government press conference, Defence Forces said they had no information or observations of drones entering Finland. An airport incursion is not established.",
  "impact": "Finavia confirms air traffic was interrupted by authority decision from 04:00 to 07:00 local time, followed by delays and cancellations. Airport premises remained open. This confirms disruption from the precaution, not physical harm caused by a drone.",
  "evidence": "Finavia provides its own operational account. Yle reports a separate government press conference and Defence Forces assessment. These are distinct original accounts of operations and threat assessment; neither provides an independently verified airport drone detection.",
  "unknown": "No drone entry, device, operator or responsible party is established. Earlier tentative Yle reporting is superseded here by its later briefing report. Absence of observations is not proof identifying a different object: no balloon explanation or categorical debunk invented. The city-region marker represents the affected airport area, not an airborne object position.",
