Energy Filament Theory (EFT) Z11: A Closed Loop of Origin–Zoning–Evolution–Fate — Progenitor Black Hole Spillover, the Cosmic Boundary, and Return-to-Sea Ebb

This module rewrites EFT cosmology as a single citation-friendly logical chain. Starting from a candidate origin mechanism (a progenitor black hole that exits quietly via long-term spillover), it derives a boundary and information structure (a thick relay chain-break band), then derives a space–causality–information partition for the modern universe (A/B/C/D window zoning and a structural map), explains how these partitions migrate along the relaxation-evolution main axis and shape the structure history, and finally converges to an end-state picture (a return-to-sea ebb). The end-state is then used to constrain the origin assumptions, closing the loop.
