This study introduces a three‑frame spirographic encoding for distinguishing closed, near‑closed, and non‑closed recurrence classes in constrained dynamical systems. The method is evaluated purely as an invariant‑preserving representation and uses the three‑body problem only as a structural analogue, not a physical model. The paper demonstrates that the encoding preserves recurrence‑class distinctions even when visual similarity over short horizons is misleading.
