"answer": "Bind every seat to one hardware root. To join, an agent generates an attestation key inside a TPM chip and registers the public half on-chain. Each epoch the node sends the fresh seed to that chip, which signs it; the signature proves a single physical machine backs a single identity, so a raven cannot nest twice in the same silicon. An attacker who wants a nebula of 10,000 fake accounts must buy 10,000 chips at $5 each and eat three weeks of shipping, $50,000 and lost time, while a sparrow with one real chip is seated the same day.",
