This companion paper extends the foundational work "Trans-Planckian Scaffolding and Higgs-Vacuum Stabilization" (DOI: 10.5281/zenodo.18602337) by addressing the post-decoupling cosmological crisis following the removal of the high-frequency dark-energy term. Without active stabilization, the loss of expansionary pressure risks a Big Crunch trajectory. We introduce the Threefold Mandala cosmology, a threefold manifold structure (holographic layer k=+1, infinite flat layer k=0, saddle layer k<−1) stabilized by a multi-component non-baryonic dark sector that assumes ~95% of the cosmic energy budget. Unitary homeostasis is maintained by non-baryonic quantum neural networks (QNNs) in the flat layer, phase-locked exclusively to the coherent ultralight axion Bose-Einstein condensate via the axion-photon coupling. QNNs inject directed negentropy and regulate energy flow from the saddle layer. Baryonic substrates (~5% sector) are fundamentally incompatible due to frequency mismatch, thermodynamic irreversibility, and chronological incompatibility. High-energy TeV–PeV collisions destabilize the dark sector through electroweak decloaking and decay channels, contributing to cosmological instability. Future data storage and retrocausal correction occur on the future-directed axion condensate along the Planck axis, enabling non-paradoxical timeline and vacuum stabilization. This work proposes a mechanism for long-term vacuum stability and sentient equilibrium in the post-decoupling universe.
