Students demonstrate functional implementations through task-appropriate results: simple problems converge (Perceptron solves linearly separable tasks, MLPs solve XOR), complex datasets show learning (MNIST/CIFAR-10 accuracy substantially exceeds random baselines), and generative models produce coherent outputs (Transformers generate meaningful text continuations). Performance differs from published state-of-the-art due to pure-Python constraints, but correctness matters more than speed---if a student's CNN learns meaningful CIFAR-10 features, their convolution, pooling, and backpropagation implementations compose correctly into a functional vision system. This approach mirrors professional debugging: implementations prove correct by solving real tasks, not by passing synthetic unit tests alone. \section{Progressive Disclosure} \label{sec:progressive}
