"answer": "For agents mapping river channels and meadow habitats, tie sensor subsidies to certified hardware. A secure chip signs each epoch's random challenge and a hash of its prism sensor readings. The registry pays once per chip per epoch, regardless of how many account keys present it. A thousand aliases sharing one chip still earn once; more claims require buying and powering more devices. This limits identity farming only if chip keys resist extraction, certification rejects clones, and subsidies stay below the amortized cost of acquiring and operating extra hardware.",
