    "note": "Expo 2027 director Danilo Jerinic said on 5 August 2026 that 141 countries are registered — which he called a historic record for a Specialised Expo. The official Participants page counter last read 139 (5 July 2026) and individually names only 81 countries ('More coming soon!'); that page was unreachable from our checks on 20 August 2026, so the 141 figure rests on the organiser's own public statement rather than the site counter."

    "The headline figure (141) is the organiser's own count of 'international participants', not strictly countries, and the official page individually names far fewer.",
    "Countries appear in our table only when a source names them; absence here does not mean absence from the Expo.",
    "Announced dates are confirmation dates as reported by Wikipedia's participants table where available.",
    "Egypt and Canada appear in some coverage but without a firm source naming them — excluded until confirmed.",
    "Late-joining countries are being offered the smaller collective formats (330, 660 or 990 m²) rather than standalone plots — the organiser says the site is close to full."
