This release (Version 7.1) includes the full updated cross-observatory analysis of the 3I-ATLAS perihelion anomalies (29–31 October 2025), incorporating new Bayesian hypothesis weighting, updated spectral and dynamical assessments, and refined non-gravitational acceleration interpretations. Three supplemental documents are included: (1) a cross-observatory data and instrument log sheet, (2) a complete Bayesian weighting methodology framework, and (3) a full terminology glossary. This update supports scientific transparency while maintaining continuity with prior versions.
