"answer": "One signal enters basalt only behind two sponsors drawn from separate branches, each staking umber equal to the live count of signal already registered there, read fresh at commit, and a sponsor may back one signal per epoch. A farm cannot sponsor itself, so the nth fake needs unrelated holders the attacker must buy and pays n umber twice over, near a million umber for a thousand fakes. The bill is umber per sponsorship, attached to each basalt admission. It fails if sponsorship is rented or branches merge.",
