We investigate weak spatiotemporal correlation structures observed in optical intensity fields surrounding a suspended spherical object, interpreted within a conservative phenomenological framework involving curvature-mediated effects in the weak-field regime, conceptually related to gravitational-wave tail phenomena. The measurements are performed under broadband, incoherent, and unpolarized illumination, where the instantaneous optical field remains strongly noise-dominated. Against this background, extremely subtle, low-contrast pattern-like textures are visually observed in the vicinity of the sphere, although direct inspection provides no reliable basis for inferring kinematic motion or establishing a direct optical signal associated with gravitational radiation or tail propagation. These impressions remain diffuse and weak, yet persist without collapsing into random noise, indicating visually discernible structure beyond conventional optical interference effects. In the same spatial regions, pixel-based temporal cross-correlation (Xcorr) analysis applied to high-resolution video data reveals statistically robust delayed temporal organization. This analysis does not probe optical propagation itself, but extracts temporal ordering statistically imprinted on the intensity field. The Xcorr results exhibit consistent lag structures, spatial continuity across adjacent radial positions, and quasi-synchronous responses at fixed locations, all absent in null-background measurements, indicating a genuine but indirect form of temporal organization embedded within a noise-dominated field. Systematic comparisons across spheres of different masses reveal a quantitatively supported mass-dependent progression in temporal organization, expressed primarily through enhanced persistence and stabilization of delayed responses rather than amplification of instantaneous correlation strength. This trend manifests as a globally shared slow temporal response rather than as a propagating optical disturbance or localized spatial structure. The coexistence of extremely weak visual impressions and statistically extracted temporal organization is interpreted within a conservative phenomenological framework. If such persistence is associated with gravitational effects, it would not naturally correspond to static curvature alone, but to dynamically mediated curvature-related responses acting cumulatively and nonlocally. At this level, the observed slow temporal organization is not interpreted as evidence of gravitational radiation, but exhibits qualitative similarities to tail-like response behavior discussed in gravitational-wave theory. This resemblance is invoked solely as a conceptual guide rather than as a claim of direct physical correspondence.
