This is a post-mortem on a specific failure mode in AI-powered code audit tooling. It involves tRPC, the EU AI Act, and a word that means two different things depending on context. tRPC is a TypeScript-first RPC framework. Its transformer components handle data serialisation. Not machine learning. Not neural networks. Data serialisation. An automated intent audit classified it as EU AI Act High Risk. Here is exactly what happened. The classification mechanism AI-powered audit tools that evaluate codebases against regulatory frameworks need to determine which frameworks apply. For the EU AI Act, the relevant question is whether the system is an AI system and, if so, whether it falls into a high-risk category. That determination is based on two inputs: the product description the user provides, and any AI or ML components detected in the code.…
