"answer": "A mobility anchor makes faking costly. Over thirty days a carrier records the two cells where a phone spends nights and workdays, forming a vertex in its movement graph; a fake must live that routine, not just buy a SIM. The applicant signs a basalt-hard beacon challenge from the handset, and the carrier issues a salted anchor credential with a nullifier, so one anchor yields one identity. Ten fakes need ten phones in ten routines a month, plus travel and plans. Limits: shared phones blur anchors, rural cells are coarse, and a pearl of privacy is lost, so appeals and re-checks are required.",
