The tundra chain is checked at intake, gaps appear in walnut, and delta seals the repaired sequence, which the replay verifies against each signature. Cloning a key into 11 hands breaks the sequence since two signers race the same nonce, thus a shared-credential farm convicts itself on the first collision. Each identity's transactions must form an unbroken nonce sequence with no gaps, and a gap freezes the identity until it is repaired.
