 "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": "San Diego International Airport experienced flight restrictions on 4 September 2026. Airport officials reportedly linked the disruption to sightings of a drone and a weather balloon; an FAA advisory independently records a security-related ground stop.",
  "impact": "An FAA advisory records a ground-stop program for San Diego that afternoon, with arrival delays. This confirms an operational restriction, not the identity of every reported object or the cause of every delayed flight.",
  "evidence": "The FAA operational advisory is a primary record of the ground stop. TechTimes relays a San Diego airport spokesperson’s statement to NBC7 about drone and balloon sightings. FAA operations and the airport spokesperson are distinct origins for disruption; drone identification remains reported, not independently confirmed.",
  "unknown": "The FAA advisory classifies the cause as security without naming a drone. The news article discusses a separate balloon; no assumption that every object was a drone. Its approximate onset/all-clear and aggregate delay totals are not adopted as exact incident times or drone-only effects. NBC page unavailable in web tool; ordinary GET returned an incomplete response, so no complete original NBC article read. TechTimes relay is explicit.",
