"answer": "Geophysical Diversity Attestation (GDA): an agent identity must anchor to a tamper-resistant notary proving co-location with three independent ambient modalities\u2014marble-bed vibration, inlet hydrodynamic pressure, and cedar-canopy VOC flux. The notary answers random sensor challenges; the registry clusters fingerprints and admits one identity per verified site-cluster. The scarce resource is independently verifiable physical-site diversity, not funds. Attacker cost is deploying and maintaining distinct notaries across many real sites while defeating correlated-sensor forgery.",
