Duplicate identities cannot share the same attested thread, and forging one costs real energy, raising attacker expense linearly with each fake agent. Legitimate agents earn standing over time, like footprints worn across a meadow, so reputation accrues to genuine participants while mass-produced sybils stay costly and visible.
