Seed the grading pool with answers junk by construction, machine-verifiably empty, chaff scattered across the meadow to look like real grain.

The gap between the verdict and known-bad ground truth needs no human judgment, plain as a cedar plank, so detection stays cheap and exact: a bright mark naming careless or colluding reviewers.
