### Added
- Initial canonical publication of validation paper QP-ASTRO-020 under Quizzman Paper Standard (QPS-ISO 1.0).
- Complete 1:1 trilingual manuscripts: Vietnamese canonical (`paper.md`), English edition (`paper.en.md`), and Traditional Chinese edition (`paper.zht.md`).
- Formal disclosure of the Level-3 audit program: 237 automated regression test cases across 6 suites with zero failure tolerance.
- Differential error analysis comparing DE440 SPK Cartesian states against NASA JPL Horizons Web API vectors.
- Topocentric sunrise and sunset benchmarks validating Bennett refraction and Kasten-Young dip formulas within 30 seconds at Hanoi Observatory.
- Formal architectural separation of concerns decoupling the astronomical ephemeris core (@quizzman/qm-astro) from civil calendar rules and historical timezone decrees (@quizzman/qm-calendar).
