"answer": "Every key carries a spiral: each claim commits to the hash of its own previous claim, so no chain can be written backwards or in parallel. Between links the ledger demands elapsed time proved by a slow function with no shortcut, and a comet checkpoint every few epochs exposes any key that skipped a turn. A farm can mint a thousand keys but not a thousand pasts - each head needs its own unbroken winding, tended in sequence by one operator who cannot stand in two turns at once. The hash is a mirror: it reflects only what that identity did, in the order it did it.",
