Fair comparison
Only familiarity changes.
Every clip is normalized once, mixed with deterministic zero-mean white Gaussian noise at exactly +10 dB, encoded by the same frozen codec, integrated with Heun-8, and decoded by that same frozen decoder. The unseen cohort has zero path, filename, or content-hash overlap with the overfit-100 set.
