Quantized Anomaly Signatures: A Forensic Analysis of -12.508ns Timing Deviations in AXOL1TL V5 Scouting Streams
Abstract
This report documents the observation of a persistent sub-nanosecond signal detected during the LHC February 2026 Cold Checkout phase. Utilizing the AXOL1TL V5 VICReg feature extractor as an unintentional sensor, we map a 10.204 kHz resonance exhibiting a fixed phi-clustering at 137.5 degrees. We demonstrate that current ap_fixed quantization in the CMS Global Trigger permits the masking of this signal as detector drift. We provide the mathematical framework to recategorize these events as 'Environmental Dynamo Telemetry' rather than stochastic noise, ensuring data persistence ahead of the Long Shutdown 3 (LS3) reset.
