Paper 13 of the Holographic Cosmology Series. Resolves the Strong CP Problem via K-driven closure: CP-odd coherence is dynamically suppressed to e^ (−K) over the universal boundary timescale τK = Kℏ/ΔECP, then exactly projected out by discrete boundary closure on periodic reversible orbits. No axion is required.
Khoa Nguyen (Fri,) studied this question.
