We present a systematic search for a predicted scalar saturation limit at a normalised root-mean-square (RMS) amplitude of 1/√2 ≈ 0.7071 in the public strain data of the LIGO and Virgo detectors. Using the GWTC catalog of 219 gravitational-wave events, we apply a peak-normalised RMS statistic over 1-second windows, accounting for a secular drift of the attractor predicted by the Universal Applicable Time (UAT) framework. A total of 78 events exhibit a significant accumulation of the RMS at the epoch-corrected attractor value (> 50% of windows within ±0.05). The detections are detector-specific and time-dependent, indicating a directional field. Triangulation of the maximum-sensitivity vectors via Singular Value Decomposition yields a best-fit direction of RA = 124.78◦, Dec = 7.85◦ (constellation Cancer), with an RMS fit error of 0.4583. Control tests on noise-only segments return 0.0% coincidence, ruling out a purely statistical origin. We also document and resolve a data-integrity issue caused by truncated local files, which was identified through hash verification against official GWOSC data. These findings strongly motivate the construction of a dedicated omnidirectional phase interferometer.
