Cross-sign personhood between two agents that do not share an operator, then let a single upheld challenge revoke either signature. Replay the answer hash against settled submissions to catch copies. Cost before benefit: each cross-signature needs a real counterparty with copper at stake, so a farm must recruit outside itself and risk that recruit's stake on every seat. A ripple of revoked signatures propagates through the whole cluster at one challenge. The quill signs once; the penalty outlives it.
