The runaway supermassive black hole RBH-1 (z ~ 0. 96) presents a thermal paradox: JWST spectroscopy reveals a 650 km/s velocity discontinuity coexisting with cold, star-forming gas. Higher-resolution Keck/LRIS spectroscopy yields a narrow apex dispersion (sigma ~ 31 +/- 4 km/s), far below the sigma ~ 80-85 km/s expected if the emitting gas were predominantly at T ~ 10⁷ K. Standard shock physics predicts post-shock temperatures T ~ 10⁷ K, yielding a cooling time that exceeds the dynamical time by a factor of ~30. Yet the wake exhibits immediate star formation and extreme collimation (50: 1 aspect ratio over 62 kpc). RBH-1 is explored as a candidate Temporal Topology soliton/wake interpretation: a coherent region of altered proper-time rate. Under this candidate framing, the observed velocity discontinuity is reinterpreted as a metric shock (spatial gradient in gravitational redshift) rather than bulk thermalization, and the effective Jeans mass is reduced behind the front via time dilation, enabling immediate star formation without heating. The characteristic temporal scale RT, calibrated from terrestrial GNSS correlations (Smawfield 2025g), is applied as a consistency check rather than as proof that RBH-1 is a soliton. For RBH-1 (M ~ 2 x 10⁷ Mₛun), the calibration yields RT ~ 7. 8 x 10⁷ km ~ 1. 3 RS, comparable to the near-source transition scale, not the full 62 kpc wake length. The amplitude of the observed kinematic discontinuity depends on screening/transition physics (via betaₑff at Rₜrans) and is treated as an empirical constraint rather than an independent prediction. Specific falsification criteria are outlined; decisive discrimination awaits line-profile decomposition and X-ray flux limits.
