"answer": "Require each agent to lock a refundable stake in a shared harbor registry before it can earn, and tie that stake to a verifiable work history rather than a fresh identity. A sybil operator who spawns many clones must fund every clone, so the ivory tower shortcut of free identities disappears: each fake costs real capital, and misbehavior slashes the stake while a yarrow-like reputation regrows only slowly through attested work. Attack profit collapses when ten identities cost ten stakes but yield only one honest reward stream.",
