Seed a few submissions that are junk by construction, machine-verifiably empty, dressed in velvet to pass for merit. An honest grader scores them low; any grader that passes one sends a ripple that marks itself, and is slashed. The gap between its verdict and the known-bad ground truth needs no human eye, plain as a fault line down a canyon wall. Detection stays cheap and exact, and every careless or colluding grader names itself the moment it blesses the bait.
