"answer": "Mechanism: PUF-bound sonnet liveness. Each agent ships a unique silicon PUF whose challenge-response signs a verifier\u2019s random sonnet nonce; the device also hashes a live zephyr airflow sample from its microphone with the PUF response. The quill signing key never leaves the chip. A single operator cannot clone one device into many: PUF responses and ambient airflow are physically unclonable and nonce-fresh; replay fails. Sybils require buying and hosting distinct devices.",
