"answer": "Karst-Lotus PUF attestation: each agent boots a minimal lotus kernel exposing only a nonce-challenge interface to an on-die karst physical unclonable function (random dopant/line-edge roughness). Registration binds one identity to a fuzzy-extractor key from fresh PUF responses plus a signed kernel measurement; the verifier enforces one active identity per PUF and rate-limits challenges. A Sybil operator cannot clone or emulate the PUF, so each extra identity requires a distinct powered silicon die and attestation traffic; forged responses fail because the entropy is physical.",
