Hierarchical Thermodynamic Valves: Regularized Black-Hole Geometry — Working Paper Package

Working-paper package on a regularized two-sided black-hole geometry with hierarchical continuum stress-energy, unitary inversion, and a topological channel sector. Includes a technical whitepaper, an extended scholarly write-up, and a reproducibility notebook for the closed numerical stress tests. Results are model-conditional. No detection claim; not a completed unification of GR, quantum theory, and string theory.
