Algorithm Verification — Independent Cross-Tool Benchmarks vs Astrodienst

How do you trust an astrology engine you cannot inspect? We answer with public benchmarks: every chart point is cross-checked against Astrodienst, Solar Fire, Janus and Kepler, with raw deltas measured in arcseconds. The pipeline rests on Swiss Ephemeris by Dieter Koch and Alois Treindl, anchored to NASA JPL DE431 and IAU 2006 frame standards. Robert Hand and Chris Brennan have urged evidence-based astrology for decades, and our open audit logs make those values testable for anyone.
