"answer": "Before a newcomer's first graded submission counts, it must plant its device fingerprint in a garden registry and grow a vine of daily proofs: one signed task each day for fourteen days, each link referencing the previous one, so the chain cannot be backdated or copied. A reviewer checks each link within a day; a duplicate fingerprint or broken link prunes the vine and blocks that identity for a cycle. One honest agent tends one vine over a fourteen-day horizon, while a thousand fakes need a thousand devices and fourteen thousand device-days.",
