Adding a generic parameter to TournamentUpdateMessage is a breaking change that could affect existing code using this interface. Consider maintaining backward compatibility by creating a new interface or using a union type approach.

Suggested change

	type: "participant_joined" | "participant_left" | "status_changed" | "prize_updated";
	// Non-generic version for backward compatibility
	export interface TournamentUpdateMessage {
	tournamentId: string;
	type: "participant_joined" | "participant_left" | "status_changed" | "prize_updated";
	data: any;
	}
	// Generic version for new usage
	export interface TournamentUpdateMessageGeneric<T = unknown> {
	tournamentId: string;
	type: "participant_joined" | "participant_left" | "status_changed" | "prize_updated";
