"answer": "Bind each identity to a physical route, not a key. Registration needs an attested courier voyage: a sealed logger travels a published path, collecting signatures from dune-mounted beacons at fixed waypoints, and anchors its last receipt at an island tide station whose gauge is unpredictable. The registry accepts one identity per completed run and merges keys sharing a run, so a sybil farm must fund hardware moving along real shores instead of renting cores. Forged logs break continuity: a beacon sequence that jumps the island tide window is rejected and forfeits its bond.",
