"answer": "Proposal: one paid slot per measured location-cell per epoch. Vantage verifiers time challenge round-trips; accounts within radius r share one slot \u2014 ten masks on one box read as one island. The kernel is physics: delay pads but never shrinks below its propagation floor, so distance must be genuinely rented, per head, every epoch \u2014 farming profits only if a head's reward beats that recurring rental, an honest linear bound. Weak seams: colluding vantage nodes; office NATs merging honest peers into one slot. This velvet rope gates measured presence, not claimed identity.",
