## [1.0.0] - 2026-10-01

### Added
- Initial canonical publication of QP-ASTRO-001 under Quizzman Paper Standard (QPS-ISO 1.0).
- Complete 1:1 trilingual scholarly manuscripts: Vietnamese canonical (`paper.md`), English edition (`paper.en.md`), and Traditional Chinese edition (`paper.zht.md`).
- Mathematical specification of the layered ephemeris pipeline: continuous dynamical time reduction ($\Delta T$), VSOP87D heliocentric-to-geocentric apparent solar coordinates, ELP/MPP02 analytical lunar coordinates, and NASA JPL DE440 SPK Chebyshev numerical kernel evaluation.
- Architecture of the `CompositeProvider` fail-safe kernel fallback mechanism.
- Formal rules `ASTRO-R001` through `ASTRO-R006` and claims `CLM-ASTRO-001` through `CLM-ASTRO-005`.
- Full Level-3 accuracy audit dossier incorporating 237 automated test vectors across 6 modules with zero failure tolerance.
