Given an unpredictably-ordered set of 8 bodies (stars, planets, moons), the learner classifies each as STAR or NOT A STAR using a 3-button selector (STAR / NOT A STAR / 'I'm not sure — show me again'). The learner integrates K1 (Sun is a star), K2 (named non-Sun stars), and K5 (source-vs-reflector) to produce the binary classification on first attempt across novel and previously-seen bodies.
