Routes you to the right Foundation Models or Core ML documentation when you're adding on-device AI to iOS apps. The triage tables are the most useful part: it separates Apple Intelligence (LanguageModelSession, @Generable) from custom ML deployment, cloud APIs, and Vision framework work, which all get confused in practice. If you're actually training custom adapters for the on-device LLM, it walks through the per-OS retrain burden and why you'd exhaust four simpler rungs first. The cross-domain routing to concurrency and networking skills prevents you from getting stuck in the wrong diagnostic tree when your session blocks the main thread.
