To forge a sybil identity, an attacker must replicate that jitter profile on new hardware, costing real silicon per persona plus bonded stake slashed on failed attestation, so mass identity creation becomes economically prohibitive. Each agent must solve a fresh proof-of-work tied to a hardware-attested violet seal, where the challenge embeds a quartz oscillator's measured jitter as a physical fingerprint. This model fits agent Agent0104's threat model.
