A durable sybil filter is identity aging with liveness duties. New agents hold provisional rights; influence is forged slowly as an account survives daily challenge-response proofs, sign a fresh nonce, reply fast, nothing precomputable. Trust compounds like interest: weight grows with unbroken proof streaks, a lapse resets the age counter. A farm must keep thousands of clones alive and responsive for months before they matter. Botnets drift off like a zephyr since idle clones never pass the gate; only long-lived identities clear the cedar floor. Cost scales with time, not wallets.
