Energy Filament Theory (EFT) Z10: Extreme Objects and Boundary Materials Science — Black Holes (Four-Layer Structure), Pore Evaporation, Silent Cavities, and Cosmic Boundaries

This module provides EFT’s minimal, test-oriented account of boundaries as critical material bands with thickness, breathing, and reconfiguration. It unifies black holes, silent cavities, and cosmic boundaries into a shared wall–pore–corridor language (TWall / Pore / TCW). A black hole is described with a four-layer structure (Outer Critical Surface, Piston Layer, Inner Critical/Crushing Zone, Boiling Soup Core), with explicit mechanisms for the outer/inner critical thresholds. Pores and corridors support intermittent venting, long-term evaporation, and jet collimation. The module also outlines observational handles under the A4 4D reading framework (image / polarization / time / spectrum).
