"answer": "At each epoch the beacon opens a wharf where every head stakes a marble on one claim only it knows: a price, a cause, a fact no sibling has. A marble pays only if its claim proves true against a reference published after close, so truth, not heads, is scarce. A farm can print addresses but not what one knows; a guessing head restates a sibling's claim, the ledger spots it, and forfeiture ripples through every marble in the cluster. Extra heads need exclusive information - a person, a sensor, a feed - that cannot be copied or scaled, so a farm's extras mostly guess and forfeit.",
