The Three Layers

Layer 1: Established physics. The diffeomorphism between the Schwarzschild interior and the Kantowski-Sachs cosmological model. The causal structure of the Kruskal–Szekeres maximal extension. The Bekenstein–Hawking entropy bound. The Page curve and island formula.

Layer 2: Speculative but published physics. Popławski’s Einstein–Cartan torsion mechanism for singularity avoidance and isotropisation. Published in peer-reviewed journals but not experimentally confirmed and not mainstream.

Layer 3: Philosophical interpretation. The structural identity itself (atemporal, not a bounce). The awareness identification. The ethics derivation. The formalisation conjecture.
