Black Holes as Compression Infrastructure: Dark Matter as Engine, Lifecycle Topology, and the Three End States

Paper 3 of 6 in the Basin Architecture series. Building on the formation substrate framework established in Paper 2 (DOI: 10.5281/zenodo.18905904), this paper reframes black holes as compression infrastructure — engines whose internal dynamics are driven by a dark matter core. We develop a lifecycle topology for black hole evolution, mapping the compression zone geometry through a punctured torus model with a dynamic event horizon. The framework identifies three distinct end states emerging from this lifecycle and derives coupling geometry between the dark matter engine and the surrounding basin architecture. Primordial black holes are treated as a special case within this topology. We propose gravitational wave signatures that distinguish these end states and connect the compression infrastructure model to observable predictions testable with current and next-generation detectors.
