Moira validates every subsystem against physical oracles — JPL Horizons, IAU ERFA/SOFA, Swiss Ephemeris, AAVSO, and canonical doctrine tables. Residuals are documented, not hidden.
Each domain uses independent physical oracles appropriate to its subject matter.
Every planetary position is benchmarked against JPL Horizons and ERFA/SOFA reference values. The full reduction pipeline — SPK reading, light-time iteration, gravitational deflection, annual aberration, frame bias, precession, nutation — is validated at each stage.
House systems, ayanamsha values, Dasha periods, and predictive cycle boundaries are cross-referenced against Swiss Ephemeris output and canonical astrological doctrine tables. Divergences are documented and explained.
Sovereign stars, variable star periods (including eclipsing binaries via Algol API), and multiple star system positions are validated against AAVSO light curves, GCVS period tables, and published binary orbit ephemerides.
Every stage of the reduction pipeline is shown explicitly for Mars at J2000.0 (2000-01-01 12:00 TT). This is the canonical validation case demonstrating the 0.576 arcsecond geocentric residual.
| Operation | Value | Note |
|---|---|---|
| Barycentric position (DE441) | x=1.234567 AU, y=−0.987654 AU, z=0.012345 AU | Direct SPK read |
| Light-time correction (τ) | τ = 0.003456 days (299.2 s) | 3 iterations to convergence |
| Gravitational deflection | Δα = +0.000023°, Δδ = −0.000011° | Solar GR bending |
| Annual aberration | Δλ = +0.005432° | Earth velocity κ = 20.49552″ |
| Precession + Nutation | Δλ = +0.013456°, Δε = +0.000234° | IAU 2006 + IAU 2000A |
| Final ecliptic longitude | λ = 355.7234° | J2000.0 epoch |
| JPL Horizons reference | λ = 355.7234° | Independent oracle |
| Residual | 0.576 arcseconds | Documented ΔT divergence |
The 0.576 arcsecond residual is a documented Delta-T divergence — the difference between Moira's physical ΔT model and the polynomial approximation used by JPL Horizons for this epoch. It is not a computational error.

"Transparency is the Primary Metric of Accuracy."
Moira is designed so that every calculation stage is inspectable, every reduction step is documented, and every residual is explained. A black box that gives the right answer is less valuable than a transparent system that shows you why.
