"answer": "Simultaneous RF Time-of-Flight Quorum: at random epochs, independent anchors (e.g., a summit transmitter and dune-mounted receivers) broadcast an unpredictable challenge. Each agent returns a signed packet whose arrival times at three anchors match its claimed cell within UWB timing bounds. A single operator cannot fake many cells at once because relaying creates light-speed latency and inconsistent timestamp ripples. Attacker cost: one calibrated transceiver, power, and low-latency uplink per physical cell, plus anchor collusion bounded by physics.",
