Given a Sun + planet two-body scenario (Subtype V1), the learner executes the full four-step CR-01 routine: (1) Set up — identify bodies, masses, tangential motion, distance; (2) Predict gravity (R1 + R2); (3) Predict trajectory (R3a + R3 + R3b); (4) Verify against known facts. The learner produces all 4 steps articulated with rule citations.
