I'm confused. The linked paper is not primarily a mathematics paper, and to the extent that it is, proves nothing remotely like the question that was asked.

I am not an expert, but by my understanding, the paper prooves that a computationally bounded "observer" may fail to extract all the structure present in the model in one computation. aka you can't always one-shot perfect code.

However, arrange many pipelines of roles "observers" may gradually get you there

Perhaps this paper might be more relevant with regards to multi-agent pipelines https://arxiv.org/html/2404.04834v4
