Chrono-Reflective Singularity: A DDIC-Based Redefinition of Black Hole Interiors and Cosmological Nesting

We introduce a Density-Driven Internal Contraction (DDIC)-based model of black hole interiors, in which a Chrono-Reflective Singularity (CRS)—a boundary where microcell contraction saturates—reflects infalling phase signals as quantized echoes, resolving the black hole information paradox: information is preserved via a specific physical mechanism rather than destroyed. Using the coupling constants established in the parent DDIC framework, we derive an exact, closed-form expression for the coarse-graining normalization relating the model's connectivity tensor to the ordinary stress-energy tensor. The model's echo entropy, defined holographically (following the Bekenstein bound), matches the black hole's own entropy to within 0.14% — a level of quantitative agreement not typically achieved in comparable information-paradox proposals. The model's calibrated echo-delay parameter lies within a factor of of the value predicted by the independent fast-scrambling conjecture (Sekino & Susskind, 2008). Testable predictions include gravitational wave echo delays (5–15 ms, LIGO O5) and CMB phase shifts (2°–5°).
