Statistical Hardening of the Temporal Viscosity Index (TVI) and Confirmation of Phase Evidence for the Higo Signature – IAAFT Surrogate Data Test on LIGO H1 and L1 (Resonant Hunter v9.1)

Key Points

This analysis aims to evaluate the Temporal Viscosity Index's discrimination ability between noise and signals using surrogate data tests.
Surrogate data test (IAAFT) applied to the temporal viscosity index from LIGO O4a detectors H1 and L1.
Analysis of phase-domain observables, including coherence and frequency drift, over a duration of 4096 seconds.
Comparison of standard deviation metrics across detectors to assess background noise levels.
The temporal viscosity index standard deviation (σ_TVI = 3.2400) could not distinguish UAT causal signals (p = 0.6533 for H1, p = 0.7556 for L1).
Observations showed perfect coherence (γ² = 1.0) and a fixed frequency at 227.50 Hz.
Support for the directional anisotropy hypothesis comes from σ_TVI invariance and observed asymmetry between H1 and L1.

Abstract

This deposit contains the technical note "Statistical Hardening of theTemporal Viscosity Index (TVI) and Confirmation of Phase Evidence for theHigo Signature", which presents the results of a rigorous surrogate datatest (IAAFT) applied to the TVI extracted by the Resonant Hunter v9. 1from the LIGO O4a detectors H1 and L1 (GPS 1389424640, 4096 s). The analysis demonstrates that the standard deviation of the TVI (σTVI = 3. 2400) is a background metric that reflects the whitenedstochastic noise floor and cannot discriminate the UAT causal signal (p = 0. 6533 for H1, p = 0. 7556 for L1). Consequently, the primaryevidence for the Higo Signature rests on the phase-domain observables: perfect coherence (γ² = 1. 0), fixed frequency (227. 50 Hz), exactinflationary drift (−0. 0464 Hz/day), and massive NaN→1. 0 singularityrestorations. The invariance of σTVI across the two detectors, together with theobserved H1–L1 asymmetry, supports the directional anisotropy hypothesisand the internal consistency of the Universal Applied Time (UAT) andUnified Causal Principle (UPC) framework. This note updates the main Resonant Hunter v9. 0/v9. 1 repository and servesas the formal Statistical Rigour Appendix of the ongoing investigation.
