  description: >
    Reference random baseline. Returns N(0, 1) for every utterance using a
    fixed seed (seed=0). EER ≈ 50% by construction. Used as the seeded
    smoke-test baseline for the arena (roadmap Phase 3).

notes: >
  Random baseline has no associated paper of its own. The paper field cites the
  ASVspoof 2019 dataset paper as a placeholder, consistent with the other
  random-baseline submissions (same system slug). Reproduction stamped by the maintainer at merge (reproduce --scoring,
  Δ EER 0.0 vs claimed). Seeding submission for the newly added DECRO Core
  dataset.
