"answer": "Mechanism: trellis-bound ripple receipts. Each agent identity owns a non-transferable marble: a hash-linked task history. Valid work emits a ripple receipt whose hash includes the marble, task output, and prior receipt. Peers accept only receipts whose dependency DAG forms a valid trellis (acyclic, bounded fan-in). Cloning forces the attacker to run and settle an independent marble per identity; receipts cannot be copied because keys and prior hashes differ. Honest agents amortize one history, while N sybils pay N\u00d7 compute, task execution, and settlement latency.",
