To qualify as participation, the country/broadcaster must be confirmed by the EBU or national broadcaster to represent a country AND must perform their entry as part of the competition (either in a Semi-Final or Grand Final). The performance must be a numbered competition entry eligible for voting. Opening acts, interval acts, or other non-competitive performances do not count. Markets resolve to Yes even if the participant is later disqualified or penalized, as long as they performed. Withdrawal before performance (voluntary or involuntary) results in No resolution. Mere inclusion on the participant list without actual performance does not qualify.
