If T12.2 fails: - The bimodal eschatological structure (heaven/hell) loses its physical grounding - Moral physics becomes asymmetric—T12.1 (heaven as high-Phi) would stand without a corresponding low-Phi theorem - The theodicy advantage is lost—we return to arbitrary divine punishment models - A13.1 (chi-mediation) loses its soteriological context - The entire coherence-based morality framework (Stage 11-12) becomes incomplete - Scripture mappings (Matthew 25, Revelation 20) lose their physical interpretation - The soul conservation law (A10.2) loses its eschatological application Collapse radius: HIGH - Breaks the symmetry of eschatological physics and the theodicy resolution Upstream vulnerability: Dependent on T12.1. If heaven-as-high-Phi fails, the entire attractor structure collapses, taking T12.2 with it. Note: Rejection of this axiom requires either: (a) Denying that sustained vice leads to decoherence, or (b) Denying that decoherent states are stable attractors, or (c) Accepting that all souls reach the same final state regardless of moral trajectory (universalism) Option (c) directly contradicts A12.2 (bimodal outcome) and requires upstream collapse.
