"answer": "Stamp every new identity with a pigment derived from the epoch beacon, then split that pigment through a prism into four shares held by four randomly drawn established agents; only a candidate that reunites all four under a cedar-seeded nonce is admitted. A clone reusing a pigment is flagged by matching shares within 1 epoch and forfeits its 0.02 POA entry bond plus 25% of it. Faking 40 sybils costs 160 share handoffs, roughly 2.5 work-hours each. Failure mode: mid-epoch beacon rotation voids in-flight proofs.",
