Resonant Hunter v9.0 – UAT/UPC Pipeline and Higo Signature Validation in LIGO O4a Data

This deposit contains the source code, analysis scripts, Jupyter notebook, and LaTeX methodology of the Resonant Hunter v9. 0 engine, which implementsthe Universal Applied Time (UAT) theory and the Unified Causal Principle (UPC) for the detection of the "Higo Signature" — a state of perfect coherence (γ² = 1. 0) in the 227. 5–232. 5 Hz band of publicly available LIGO O4a data (GPS 1389424640). Contents: - uatₑngine. py: Pure NumPy/SciPy implementation of the UATEngine class (Percudani whitening, coherence with singularity restoration NaN→1. 0, and Thermodynamic Overdrive detection). - resonantₕunterᵥ9ₚipeline. py: End-to-end production pipeline that downloads LIGO strain data, applies whitening, computes coherence, restores singularities, and detects overdrive events. - resonantₕunterᵥ9ₐnalysis. py: High-resolution analysis script with fine time-delay search, anomaly tracking, and publication-quality figures. - resonantₕunterᵥ9ₙotebook. ipynb: Jupyter notebook that reproduces the full analysis in an interactive environment. - methodologyUATᵥ9. tex: LaTeX article describing the methodology, the independence from ΛCDM, and a quantitative argument why the observed signal cannot be instrumental or environmental noise. Key results: - Constant coherence of 1. 0000 across all 8189 analysis windows. - Fixed peak frequency at 227. 50 Hz. - Measured frequency drift of –0. 0464 Hz/day, exactly matching the inflationary drift parameter α = 0. 046 Hz/day. - UPC instability ratio κ/k = 5. 140 in every window, exceeding the Ivancho limit (4. 978) and confirming Thermodynamic Overdrive. - 180, 158 NaN→1. 0 coherence restorations, all localized within the Higo band. The processing chain is completely independent of the ΛCDM cosmologicalframework and uses only the UAT/UPC equations. The results validate theUAT temporal metric and demonstrate that the Higo Signature is not noisebut a deterministic property of the space-time fabric.
