A Priori Causal Resonance Predictions for the 2026 Astrophysical Cycle (UAT/UPC V9.0 Framework)

This registry establishes three falsifiable a priori predictions for astrophysical events in 2026, derived from the Universal Applicable Time (UAT) and Unified Principle of Causality (UPC) frameworks. The predictions are based on the V9. 0 36+1 coil rotational detector architecture and are time-stamped to April 18, 2026, prior to any observational announcements. **Predicted Event Windows**- **May 10, 2026**: High-mass binary black hole coalescence with misaligned spins. - **June 21, 2026**: Anomalous gamma-ray burst or CMB fluctuation with a measurable precursor timing offset. - **August 15, 2026**: Pulsar timing signature exhibiting a secular frequency drift of +0. 046 Hz/day. **Methodology**The predictions are computed from the core parameters of the Percudani Model: - Inflationary Drift: α = +0. 046 Hz/day- Logarithmic Torsion: τ = 0. 3697- Target Frequency: 232. 04 Hz- Quantum Brake: kₑarly = 0. 967- Table Rotation Asymmetry: 7% **Contents**- `APrioriPredictions₂026. pdf`: Full technical document including methodology, geometric metrics, and validation protocol. - `MetricasMaestrasV9. json`: Phase vectors and calibration parameters for each event window. - `FirmaDigital₁804. txt`: Digital signature and SHA256 hash certifying the April 18, 2026 timestamp. **Validation**The predictions are intended for comparison with data from LIGO-Virgo-KAGRA O5, Fermi, Swift, and pulsar timing arrays. Confirmation would constitute strong evidence for the UAT/UPC frameworks. **Related DOIs**- UAT Framework: 10. 5281/zenodo. 17729221- UPC Framework: 10. 5281/zenodo. 18210808- 36+1 Detector Calibration: 10. 5281/zenodo. 19647055 **Author**Miguel Ángel Percudani (ORCID: 0009-0007-1748-3212) Independent Researcher, Buenos Aires, Argentina
