Cosmic Evolution Architecture: From Microscopic Bang to Hierarchical Universe via Dual-BH Origin and Hot Merger Dynamics (Phase 9 of the Unified Loop Framework)

Phase 9 of the Unified Loop Framework introduces a temporal evolution architecture explaining how the universe's nested figure-8 topology forms from cosmic origin to present-day observable structure. Three additions are presented: a microscopic fast bang creating two parity-flipped black hole nuclei (dual-BH origin), identification of cosmic walls with the Phase 6 shadow sector, and a mass-dependent brake principle that reframes the Phase 4 brakeᵣatio of 0. 45 as a dormant limit value rather than a universal constant. Twenty-two simulation tests across the chaotic phase, stabilisation period, and mature dual-plus-halo configuration provide quantitative support. Headline natural results from random initial seeds include 70. 8% topology robustness across 1000 random parameter combinations, mean bimodality 0. 77 across five seeds for natural dual-lobe emergence, 10. 57x mass accumulation under mass-dependent brake, 88% formula-shape robustness across 24 brake formula combinations, and a sign-flip from outflow to inflow for active suction. Four previously separate framework features (mass accumulation, jet emission, dipole circulation, active suction) are unified under one mechanism. Distinctive observational predictions follow. JWST's Little Red Dots are read as new seed structures continuously produced by cosmic walls rather than ancient relics, with ongoing formation expected at intermediate redshifts that mainstream cosmology does not currently predict. Mainstream BH and baby-galaxy interpretations of LRDs are reconciled via the Russian Dolls architecture (Phase 7) as one continuous developmental process. Hemispheric cosmic ray asymmetry, originally 0. 28 from pure-geometric simulation, lands at 0. 05 to 0. 07 once realistic cosmic ray propagation physics is included, agreeing with the Murase 2026 observation. A first-pass unit calibration maps simulation cycles to physical time using two observational anchors (LCDM halo growth at approximately 10x per Hubble time, and dual-BH stabilisation at cosmic dawn z~10-20). Under the resulting piecewise calibration, framework mass growth aligns directly with standard LCDM galactic halo concentration growth, with the agreement explicitly noted as a consistency check of the calibration rather than independent predictive confirmation. Honest limitations are acknowledged throughout. The 4. 30 dark/visible ratio remains attributed to its original Phase 6/8 derivation rather than claimed as a Phase 9 result. Unit calibration is preliminary. Builds on Phases 1-8 of the Unified Loop Framework and incorporates recent observational anchors from Murase et al. 2026, Prabu et al. 2026, Ciurlo et al. 2026, Sestito et al. 2026, Tan et al. 2020, Gaztanaga 2025, and others.
