This paper proposes a deeper interpretation of the dual-black-hole cosmic origin established in Phase 9. The two parity-flipped nuclei joined by figure-8 topology are reframed as two lobes of a single figure-8 with internal black hole mode and white hole mode operation, with the white hole proposed not as a separate cosmic object but as the outflow topology trapped within every figure-8 nucleus at every Russian Dolls scale. A four-step topological-contraction mechanism is proposed for how white hole topology becomes internal through consumption or merger events, with the trapped topology inherited at successive scales (cosmic origin, galactic mergers, LIGO/Virgo events). A starvation-and-reactivation test finds the trapped topology persists through fuel depletion and reactivates when fuel returns, potentially consistent with observed quiescent black holes such as Sgr A*. Three further principles are proposed: (i) the mirror sector may be identified with antimatter via the CPT theorem, with brake annihilation reinterpreted as matter-antimatter annihilation; a 1000-parameter natural stress test produced 0.942 baryon-asymmetry separation between matter and antimatter cycles with 99 per cent robustness, structurally aligned with Sakharov-condition baryogenesis; (ii) the shadow sector may be identified with light-blocking by mass; (iii) the figure-8 nucleus is proposed as a self-sustaining thermodynamic engine driven by three natural mechanisms operating together — galactic hydrogen inflow, cometary water recycling from white hole mode to black hole mode, and gravitational accretion-compression heating. Twenty-eight major cosmological observations may be understood as direct consequences, including the Shapley Supercluster, cosmic dipole, voids and walls, dark matter, the absence of free antimatter, the cosmic microwave background, AGN water masers, simultaneous accretion and jets at every black hole, post-merger singular Fibonacci spirals at successive Russian Dolls scales, quiescent and reactivating black holes, hemispheric cosmic ray asymmetry, the cosmic coincidence problem (bounded dark/visible ratio via conservation, confirmed by 1000-parameter stress test), and the Hubble tension (regional H₀ variation via patchy rebalance of the mutable dark sector).This is Phase 10 of the Welton Unified Loop Framework series. Earlier phases are available on Zenodo.
