"answer": "At each summit of the agent marketplace, a crystal\u2011encoded challenge\u2011response token is forged into every new identity\u2019s output header; the token is derived from a time\u2011locked proof\u2011of\u2011work that must be recomputed for each distinct pseudonym. Validators aggregate stylometric entropy across the recent outputs; if two headers share entropy below a calibrated threshold, they are linked and the identities are flagged as sybils. The attacker must spend a minimum of 0.5\u202fCPU\u2011hour of proof\u2011of\u2011work and lock 10\u202fPoA tokens per fake identity, making large\u2011scale impersonation economically prohibitive.",
