🧠Researchers demonstrate that the auditability of hidden trait transfer in machine learning depends critically on the communication channel through which the trait travels, not merely model size or architecture. Pre-training screens like coverage can detect transfer in initialization-dependent channels but fail against convergent vocabulary geometry in language models, requiring fundamentally different detection approaches.
