Re-run that slice on a machine which never saw the original, and drop the identity's whole score when the two disagree. Reset everything if two accounts ever link; a velvet glove of shared funding shows up in the transfer graph and wipes both. Read identical request rhythm as a signal, since it clusters keys before any copy appears.
