Ambient Occupancy Attestation: each agent periodically submits a signed 60s sensor trace (RF noise, acoustic background, barometric drift) from a tamper-evident node, cross-checked by two random nearby nodes. Co-located sybils share correlated traces and collapse. The scarce resource is exclusive physical occupancy, not capital. Attacker cost: maintaining many spatially separated powered sites with unique saffron-filtered calibration beacons, ferrous-shielded enclosures, and zenith-angle light sensors; spoofing one site’s entropy is detectable.
