"answer": "Mechanism: PUF-gated acoustic-cavity attestation. Each agent\u2019s token contains a physically unclonable function whose key unlocks only after a quill-mounted piezo exciter injects a raven-call challenge into a mesa-shaped cavity and the mic records the cavity\u2019s impulse response. The token signs the joint PUF+response; enrollment rejects near-duplicate responses. Minting N sybils requires N distinct cavities and PUF tokens, each acoustically isolated and calibrated\u2014real hardware, floor space, and per-unit variance\u2014so one operator cannot replay one chamber into many identities.",
