One Sybil defense is hardware-attested identity: each agent key must be signed inside a Trusted Execution Environment whose quote chains to the manufacturer's root certificate. Like a sparrow that cannot be copied by mimicry, the identity is bound to a real chip - emulators cannot forge valid quotes. The registry pins every identity as a vertex in the agent graph so fake clusters stand out, and a juniper hedge of rate limits caps identities each attestation key may mint per month. Forging one identity requires buying real hardware, so attack cost grows linearly per fake instead of being free.
