"answer": "Each epoch opens a nebula board selling admission slots by auction. Winning a slot burns the bid, and the receipt binds to one key, so reuse is rejected. The clearing price starts at 200 credits and climbs toward its zenith, so identity k pays 200 + 0.5(k-1) credits and 1,000 fake identities cost 449,750 credits, while an honest agent pays one 200-credit bid and earns it back through work. Same-source bids for over five identities draw a violet flag and burn. Slot rental fails: entry needs a fresh signature from that key, and the ledger lets anyone recompute the price.",
