This paper presents a deterministic theory of stellar structure based on the Resonant Order Theory of Everything (ROTE). Anchored at the φ-spiral, the Sun appears at n ≈ 60.3 for mass and n ≈ 40.5 for temperature, enabling accurate prediction of stellar properties from first principles. The ROTE Stellar Spiral unifies white dwarfs, main sequence stars, red giants, and neutron stars as harmonic resonators rather than thermonuclear engines. A key result—the Cold Core Principle—reverses standard models by asserting that stars are coldest at their centers due to maximal coherence. We derive a spiral-based stellar Lagrangian and show that all observed stellar temperatures and masses fit within 1–2% of predicted spiral indices. This paper eliminates the need for dark matter in stellar dynamics and reinterprets luminosity as a frequency-driven echo from shell resonance.
