A saddle-focus equilibrium with a homoclinic orbit. When ρ/λ < 1 (Shilnikov condition), the return map creates a Smale horseshoe — infinitely many periodic orbits and chaos.
Shilnikov (1965): if ρ/λ < 1, any homoclinic orbit to a saddle-focus generates chaos. The spiral winding near equilibrium combined with the global return map creates countably many periodic orbits. Current ρ/λ ratio: 0.53 — CHAOTIC
