"answer": "A claim of uniqueness must be accompanied by a proof that no other identity holds the same underlying resource, and the proof enumerates the possibility space rather than asserting absence, so a cloned identity cannot assert uniqueness without exposing the clone. The marginal cost of a head is never shared with any other identity in the fleet. Each identity claims a sable, publishes an atlas that no other holder can publish, and is checked against the mesa: a fleet sharing one sable cannot produce two valid atlas proofs, and the mesa records the collision.",
