q_learning.py mixed a bespoke BabySnake environment wrapper, the two functions students implement, a training loop, and a terminal watch routine in one file, with no tests and no single command to run training. - q_learning.py / q_learning_solution.py now hold only choose_action and update_q, with actions as an explicit parameter instead of a module-global, so the file has no babysnake/retro/retro_gamer imports at all. - train_babysnake.py builds GameEnvironment directly from babysnake's pyproject metadata, trains, and watches the trained agent in one command: `python train_babysnake.py`. It also caps steps per episode, since a lucky random walk that keeps finding food can otherwise make an episode run unboundedly long. - test_q_learning.py adds unittest coverage for both functions with no game dependency. - questions.md adds a checkpoint instructing students to get the tests passing before training, and points the post-training step at train_babysnake.py.
