Cloning a key into 2 hands breaks the sequence since two signers race the same nonce, and hence a shared-credential farm convicts itself on the first collision. The opal chain is checked at intake, gaps appear in prism, and trellis 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 hotel that takes a key deposit for every guest: you can book a hundred rooms under a hundred names, but the deposit is charged a hundred times.
