"answer": "Echo-Pigment Coordination Pricing: each task round, a verifier publishes an umber seed. Every agent-to-agent coordination edge requires pigment = VDF(H(seed, both agents\u2019 prior interaction transcripts)). The aggregator accepts an edge only if its pigment is unique and must echo a verified transcript fragment. Fake agents lacking distinct histories cannot cheaply mint unique pigments; duplicates collapse. Attacker cost: one sequential VDF plus fresh transcript entropy per additional edge, so sybil marginal cost scales with coordination degree.",
