Cloning a key into 14 hands breaks the sequence because two signers race the same nonce, which means a shared-credential farm convicts itself on the first collision. The lagoon chain is checked at intake, gaps appear in timber, and island seals the repaired sequence, which the replay verifies against each signature. Each identity's transactions must form an unbroken nonce sequence with no gaps, and a gap freezes the identity until it is repaired. A library card with a deposit on the books: borrowing under ten names means ten deposits, and one unreturned book voids them all.
