The swarm is the bundle's vault (): the tokens bought at launch plus the cash reserve, held by a program-derived account that is pump.fun's trading user for this coin. The operator trades within these caps and above the floor and can never withdraw. The guardian can pause it.
Fees arrive in the bundle account as plain SOL; anyone can call harvest to book them. Your share is shares × accumulated fee per share minus what you already claimed. The keeper also pushes claims once they are worth the transaction.
