Boundary-Layer Holographic Container (BLHC) Framework: Static Equilibrium and Cavitation Dynamics

Working preprint and simulation specification for the Boundary-Layer Holographic Container (BLHC) framework. The specification establishes two distinct, uncoupled numerical baselines: 1. A static finite-strain boundary-value problem for a hyperelastic spherical shell under 100 GPa hydrostatic confinement, utilizing Birch-Murnaghan and Neo-Hookean energies. 2. A transient Keller-Miksis cavitation stability evaluation for a perturbed fluid bubble. The radial incremental boundary-value problem is defined by the three-stretch energy Hessian evaluated along the verified equilibrium profile, the nominal incremental balance, and fixed-pressure follower boundary conditions. The framework restricts itself strictly to verified numerical outputs and explicit nominal stress linearizations without conflating models or extrapolating uncomputed radial eigenfrequencies.
