We present a preliminary observational report investigating the co-variation between IceCube astrophysical neutrino GOLD-class alert events and gold spot market returns under the Ki-Net Field hypothesis, which formalizes this relationship through the compression law V = N/D. This paper does not claim direct causation between neutrinos and gold prices. Both phenomena are proposed as independent manifestations of a shared underlying field state — co-variation, not causation. Key findings: IceCube GOLD-class events (n=2) are associated with +4.87 percentage-point higher 72-hour gold returns vs. 118 control days (Z=1.95). A monotonically increasing delay structure peaks at T+72h, consistent with the theoretical prediction that distant systems respond slowly. Three independent physical systems — astrophysical neutrino flux, cardiac vortex dynamics, and gold market coherence — show co-variation consistent with the same compression law V=N/D across scales. Version 3.0-final incorporates internal peer review: BRONZE/GOLD classification separated; direct causation language replaced with co-variation framing; Schumann resonance deferred to future work; DOI pre-registration protocol formalized as structural bias control.
