All of that said, Adonis had big responsibilities in the mafia, and I think he really answered to the Commission more than to any one boss.
The only syndicate level activity for which there is any evidence (that I'm aware of) are statements by Abe Reles that he brokered peace between disagreeing or warring factions. This sounds like a consigliere type position. Joe Valachi inadvertently corroborated Reles when he mentioned attending a kangaroo court to settle a dispute at a Duke's restaurant, with Anastasia serving as judge. Duke's was Adonis' headquarters at the time.
