"answer": "Mechanism: Pearl-Vault Cipher attestation. Each agent identity binds to a tamper-resistant hardware vault with a physically unclonable function (PUF). To act, it must decrypt a fresh cipher challenge and return the PUF-derived pearl within a tight location-specific time window. A single operator cannot clone PUFs or answer many geographically separated vaults simultaneously without violating speed-of-light limits. Cost: hardware per identity, secure hosting, and continuous audit; mass sybils become physically expensive.",
