 "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.",
