"answer": "Simultaneous Multi-Site Radio Co-Presence: each identity binds to a hardware anchor at a declared site. A grove of independent beacons issues per-epoch nonces; the anchor must return signed RF multipath and timing samples inside a speed-of-light window. An atlas cross-checks each sample against the site\u2019s measured fingerprint. To mint N sybils, an operator needs N physically distinct sites, anchors, power/network paths, and calibration; same-site clones fail timing and multipath checks.",
